Description

The present invention relates to a base cover installation structure and removal method.

A building such as a house is constructed on a foundation that is cast and formed in advance on a site.

Since it takes a certain amount of time to construct a building after the foundation is poured, it is necessary to protect the inside of the foundation from rainwater during that period (or to protect it from the rain).

In general, when raining on a foundation, the foundation cover is placed directly on the foundation, and the entire surface of the foundation is simply covered with the foundation cover from above. The base cover is fixed to the ground with pegs around the perimeter.

In addition, there is a large-scale one that accommodates the foundation inside the dome-shaped foundation cover by erecting pillars inside the foundation and using the pillars to stretch the foundation cover in a dome shape. (See Patent Document 1, for example).

JP-A-11-311028

When the periphery of the base cover is fixed to the ground with pegs, the pegs alone do not provide a sufficient fixing force, so there is a risk that the pegs will come off and the base cover will be blown away by the wind.

Also, when the foundation is accommodated inside the dome-shaped foundation cover, there is a risk that the support will fall and the foundation cover will be crushed or blown away by the wind.

Therefore, the main object of the present invention is to contribute to the improvement of the above-described problems.

In response to the above problems, the present invention
A foundation cover is provided to cover the foundation of the building from above,
The base cover is held by a bolt member protruding from the base via a mounting bracket or a rod-shaped member attached to the mounting bracket,
The mounting bracket includes a water fitting installed on the water side of the foundation and an underwater metal fitting installed on the water side of the foundation,
The water fitting is higher than the water fitting,
The rod-shaped member is
a horizontal horizontal member disposed along the side of the water side and supported by the water fitting;
a vertical diagonal member arranged perpendicular to the lateral horizontal member and supported downwardly by the above-mentioned water fitting and the above-mentioned water fitting;
Further, the basic cover installation structure is characterized by having an upper pressing bar disposed between the vertical diagonal members and parallel to the vertical diagonal members and placed on the basic cover from above.

According to the present invention, with the above configuration, it is possible to prevent the base cover from scattering due to the wind.

Hereinafter, this embodiment will be described in detail with reference to the drawings.
1 to 25 are for explaining this embodiment.

<Construction> The construction of this embodiment will be described below.

A building 1 such as a detached house or collective housing is provided. The building 1 may have any structure, but in this embodiment, for example, it is a unit building as shown in FIG.

As shown in FIG. 2, a box-shaped (rectangular parallelepiped) building unit 2 is manufactured in advance at a factory, transported to a construction site, and assembled and installed at the construction site as shown in FIGS. 3 and 4A. This is the building 1 that can be constructed in a short period of time.

At the construction site, the building unit 2 of the lower floor L is installed side by side on the foundation 3 (Fig. 3), and the building unit 2 of the upper floor H is installed side by side on the building unit 2 of the lower floor L. Constructed such as by side-by-side installation (FIG. 4A).

Each building unit 2 has a unit frame with a box frame structure in its skeleton portion. As shown in FIG. 2, the unit frame connects four metal ceiling beams 2b in a rectangular shape between the upper ends of four metal columns 2a, and between the lower ends of the four metal columns 2a. It has a structure in which four metal floor beams 2c are connected in a rectangular shape. An exterior wall material 2d or the like is attached to the side surface of the unit frame which is the outdoor side.

The foundation 3, as shown in FIG. 1, is a structure made of reinforced concrete for installing the building 1 at a position higher than the ground. The foundation 3 has at least an outer perimeter raised portion extending along the perimeter of the building 1 . For example, the outer periphery rising portion has a substantially closed frame shape and extends in the circumferential direction of the building 1 with a substantially constant width. The outer circumference rising portion is raised from the ground with a predetermined height h1 in the vertical direction 4. - 特許庁The outer peripheral raised portion is formed at a height of about 300 to 500 mm, preferably about 400 mm, from the ground.

The outer perimeter raised portion is formed to have substantially the same shape and size as the outer shape of the building 1 . In the case of a unit building, the outer periphery riser has the same shape and size as the outer shape of the lower floor L of the building 1 formed by arranging a plurality of building units 2 of the lower floor L. The foundation 3 may be a continuous foundation consisting only of the raised portion including the outer peripheral raised portion, or a solid foundation covering the ground inside the outer peripheral raised portion, but either of them may be used.

In this embodiment, the base 3 has a substantially rectangular shape in a plan view having a pair of parallel long sides 3a and 3b and a pair of parallel short sides 3c and 3d at the outer periphery raised portion. A plurality of building units 2 each having the same size are arranged side by side on the foundation 3 . The building units 2 are installed side by side so that the short sides are aligned along the long sides 3 a and 3 b of the foundation 3 . Therefore, the long sides 3 a and 3 b of the foundation 3 are approximately integral multiples of the short sides of the building unit 2 . The short sides 3c, 3d of the foundation 3 have the same length as the long sides of the building unit 2.

Assuming that the direction of the short side of the substantially rectangular shape is the width direction and the direction of the long side is the longitudinal direction, the above arrangement makes the width direction of the foundation 3 the longitudinal direction of the building unit 2, and the longitudinal direction of the foundation 3 the building unit. 2 width direction.

For example, the building units 2 are installed on the foundation 3 in order from one short side 3c of the foundation 3 to the other short side 3d (installation direction 5 of the building unit 2). ). However, the arrangement of the building units 2 and the shape of the outer perimeter rising portion are not limited to those described above.

For the base 3 having a rectangular shape in plan view as described above, one long side 3a is the side on the water side, and the other long side 3b is the side on the water side. One short side 3c on which the building unit 2 is installed earlier is the side upstream in the installation direction 5, and the other short side 3d on which the building unit 2 is installed later is downstream in the installation direction 5. side edge.

One long side 3a may be the underwater side, and the other long side 3b may be the underwater side. It is preferred that the side be the water side.

Hereinafter, when simply referred to as the foundation 3 , the foundation 3 mainly refers to the outer periphery raised portion of the foundation 3 .

In addition, as shown in FIG. 3, a side cover 6 is attached to the opening of the side of the building unit 2 which is the indoor side to cover the opening from drizzle. A ceiling cover (upper surface drizzle sheet or drizzle sheet 7) for drizzling the top surface is attached to the ceiling). In addition, a heat insulating material 9 is constructed inside the foundation 3 (upper peripheral portion thereof).

The temporary rain cover sheet 7 covering the upper surface of the building unit 2 on the lower floor L is, for example, as shown in the parts diagram of FIG. 4B.

That is, the temporary rain cover sheet 7 is formed so as to protrude from each of the four sides of the rectangular sheet main body covering the upper surface of the building unit 2 to cover the upper part of the four side surfaces of the building unit 2 respectively. It has two side upper cover portions 7a.

The side upper cover portions 7a are bent downward along the four side surfaces of the building unit 2, and are connected to adjacent side upper cover portions 7a by connecting portions 7b.

In addition, on the back surface of the side upper cover part 7a, the side upper cover part 7a of another temporary rain finishing sheet 7 installed on the upper surface of the building unit 2 installed adjacently, and the side upper cover part 7a that is bent upward. A second connecting portion 7c is provided that can be connected and separated from each other.

The upper side cover portion 7a having the second connecting portion 7c has, at the intermediate width portion thereof, a folding auxiliary line portion 7d extending along the longitudinal direction for assisting the folding of the upper side cover portion 7a. .

At this time, the temporary rain cover sheet 7 is formed of, for example, a flexible synthetic resin sheet made of polyethylene (polyethylene waterproof laminate sheet). The side upper cover portion 7a should be provided at least on the side where the adjacent building unit 2 exists in order to connect with the adjacent temporary rain sheet 7. As shown in FIG. The connecting portion 7b and the second connecting portion 7c are, for example, hook-and-loop fasteners. The connecting portion 7b and the second connecting portion 7c are provided at least at both ends of the side upper cover portion 7a. The folding auxiliary line portion 7d is formed by a seam line, a welding line, or attachment of a tape-like member.

In this embodiment, as shown in FIG. 5A (FIG. 5B, FIG. 6), a base cover 8 is attached to the base 3 to protect against temporary rain. Temporary rain protection is to temporarily protect the inside of the foundation 3 from rainwater during the period from when the foundation 3 is being cured or after completion until immediately before the building unit 2 is installed. If there is no risk of rainfall during the above period, no drizzle is necessary.

(Regarding basic cover 8)

The base cover 8 may have the following configuration.

(A1) A foundation cover 8 that covers the foundation 3 of the building 1 from above with a cover member 11,
The cover member 11 is divided into a plurality of cover pieces 12 according to the sizes of the building units 2 arranged side by side on the foundation 3 . Alternatively, the cover member 11 is composed of a plurality of cover pieces 12 formed according to the size of the building unit 2 .

Here, the base cover 8 is a flexible sheet-like member for covering the entire foundation 3 from above and performing a temporary rain finish inside the base 3. - 特許庁The foundation cover 8 is temporary and removed during installation of the building unit 2 .

The base cover 8 is mainly composed of a cover member 11. As shown in FIG. The cover member 11 is composed of a thin and flexible planar member (sheet or film) that can be folded or rolled. The cover member 11 is sized to cover at least the entire surface of the base 3 .

The cover member 11 is formed of, for example, a synthetic resin sheet made of polyethylene (polyethylene waterproof laminate sheet). Since this synthetic resin sheet is waterproof, inexpensive, lightweight, durable and easy to use, it is used for various purposes as a construction work sheet at construction sites and the like. This work sheet is made of the same material that is effectively used as a multi-purpose sheet in various fields such as outdoor activities, leisure activities, and disaster prevention.

Dividing according to the size of the building unit 2 means that the part of the cover member 11 that is inside the foundation 3 is divided by the position between the adjacent building units 2 so that each building unit 2 is separated. That is. Thereby, the cover piece 12 has at least a portion of the same shape and size as the building unit 2 . As will be described later, each cover piece 12 is actually slightly larger in shape and size than the building unit 2 .

The cover piece 12 is a planar member having a required size that constitutes the cover member 11 . By making the size and shape of the cover piece 12 substantially match the building unit 2 or the size and shape of the portion of the foundation 3 on which the building unit 2 is installed, the cover piece 12 is substantially rectangular in plan view. shape. Then, the cover member 11 can be removed from the foundation 3 while being turned over by the size of the building unit 2, and is easy to handle.

In order to turn over the cover pieces 12 well from the foundation 3, the cover pieces 12 are arranged on the foundation 3 in order in a direction opposite to the installation direction 5 of the building unit 2 (cover Installation direction 13) of piece 12).

As a result, the installation direction 5 of the building unit 2 and the installation direction 13 of the cover piece 12 are opposite to each other between the upstream side and the downstream side. That is, with respect to the installation direction 13 of the cover piece 12, the other short side 3d of the foundation 3 is the upstream side, and the one short side 3c of the foundation 3 is the downstream side. Hereinafter, in order to avoid confusion, the term "short side 3c side" and "short side 3d side" may be used.

Then, the cover pieces 12 are placed in order from the other short side 3d of the foundation 3 toward the one short side 3c of the foundation 3, partially overlapping each other (FIG. 8). At this time, the other side edge in the width direction (short side 3d side) of the later cover piece 12 is placed on one side edge in the width direction (short side 3c side) of the previously installed cover piece 12. be superimposed.

For example, as shown in FIG. 7, the cover piece 12 includes an inner surface covering portion 14 that mainly covers the inner portion (inner surface) of the base 3, and side surfaces integrally formed at both ends of the inner surface covering portion 14 in the longitudinal direction. and a covering portion 16 . The inner surface covering portion 14 is at least a surface having a substantially rectangular shape in a plan view with substantially the same size and shape as the bottom surface of the building unit 2, or a surface larger than that. The side surface covering portion 16 is a surface that covers the side surfaces of the waterside and waterside sides (long sides 3a and 3b) of the foundation 3 from the outside. Although the boundary between the inner surface covering portion 14 and the side surface covering portion 16 is not necessarily clear, it appears as a crease when the foundation 3 is covered.

Moreover, the cover piece 12 has overlapping portions 18 and 19 that overlap the adjacent side edge portions of the adjacent cover pieces 12 . The overlapping portions 18 and 19 preferably extend to a length reaching the installation position of the building unit 2 covered by the adjacent cover strips 12 or to a length exceeding the installation position of the building unit 2 . The boundary position between the overlapping portions 18 and 19 in the inner surface covering portion 14 is not necessarily clear, but appears when the cover pieces 12 are overlapped with each other.

Furthermore, some of the cover pieces 12 are provided with a side covering portion 17 that covers the side surfaces of the short sides 3c and 3d of the base 3 from the outside at one side edge. The boundary between the inner surface covering portion 14 and the side surface covering portion 17 is not necessarily clear, but appears as a crease when the foundation 3 is covered.

All the cover pieces 12 are provided with side covering portions 16 that cover the side surfaces of the long sides 3 a and 3 b of the base 3 . On the other hand, the side covering portions 17 covering the side surfaces of the short sides 3c and 3d of the foundation 3 are provided only on the cover pieces 12 installed first and last.

FIG. 7 shows an example of the basic cover 8 having the most basic configuration. The base cover 8 comprises a first cover piece 12 (Fig. 7(c)) installed first, a single or a plurality of second cover pieces 12 (Fig. 7(b)) installed in the middle, The third cover piece 12 (FIG. 7(a)) installed last and three different types of cover pieces 12 are provided. The first cover piece 12 and the third cover piece 12 are integrally provided with side covering portions 17 on side edge portions on different sides, and the second cover piece 12 is not provided with the side covering portions 17. are the main differences.

Of these, the side covering portion 16 is provided with a constant width along both longitudinal end edges (short sides) of each cover piece 12 . In addition, the side covering portion 17 is provided with a constant width or different widths along one side edge (long side) of the first and last cover pieces 12 on the side where the adjacent cover pieces 12 are absent. .

The overlapping portions 18 and 19 are formed at least at the portions of the side edges (long sides) of each cover piece 12 that overlap the adjacent cover pieces 12 . A portion of the side edge (long side) of each cover piece 12 that does not overlap with the adjacent cover piece 12 is a non-overlapping portion. The non-overlapping portion is narrower than the bottom surface of the building unit 2 due to the presence of the overlapping portions 18 and 19 .

Among them, the overlap portion 18 is a portion above the overlap, and is provided on the side edge portion of the cover piece 12 on the side of the short side 3 d of the foundation 3 . The overlapping portion 18 is provided at least in the area of the inner surface covering portion 14 but may be sized to extend to the side surface covering portion 16 . The overlapping portion 18 is not provided on the first installed cover piece 12 .

The overlapping portion 19 is a portion below the overlap, and is provided on the side edge portion of the cover piece 12 on the side of the short side 3c of the base 3 . The overlapping portion 19 is provided at least in the area of the inner surface covering portion 14 but may be sized to extend to the side surface covering portion 16 . The overlapping portion 19 is not provided on the cover piece 12 that is installed last.

In addition, as shown in FIG. 5B, the cover piece 12 has one or a plurality of attachment holes 22 through which a string-like member 21 such as a band is passed, and an attachment auxiliary portion 23 . The attachment auxiliary portion 23 can be, for example, a packet (string threading piece) having an attachment hole 22 or a loop-shaped band. The attachment auxiliary portion 23 is mainly provided on the back surface side (lower surface side) of the cover piece 12 . The string-like member 21 may be used to directly fix to the foundation 3 or the like, or may be used to fix to the ground with a peg 24 or the like. The mounting holes 22 are appropriately provided at positions such as the edge portions of the side covering portions 16 and 17 . The attachment auxiliary portion 23 is appropriately provided at a position around the edge portion of the inner surface covering portion 14 or the like. The cover piece 12 and the mounting hole 22 of the bucket may be reinforced with an eyelet.

Note that the configuration of the base cover 8 is not limited to the above, and can be modified, for example, as shown in FIGS. 24A to 24E. This modification will be described later.

(A2) As shown in FIG. 7, the cover piece 12 has connecting portions 32 and 33 that can be connected to each other at the side edge portions located at the boundaries 31 (for example, FIG. 3) between the building units 2. Also good.

Here, the boundary portion 31 is a position that is substantially directly below the mutually adjacent lower sides (adjacent floor beams 2c) of the building units 2 that are installed adjacently on the foundation 3 .

The side edges of the cover piece 12 (on which the connecting portions 32 and 33 are provided) are the side edges that become the overlapping portions 18 and 19 . The connecting portions 32 and 33 are not particularly required at the side edge portions where the adjacent cover pieces 12 do not form the overlapping portions 18 and 19 .

If the connecting portions 32 and 33 are not provided, the cover pieces 12 are simply installed by arranging or superimposing them so that there is no gap. is preferred.

The connecting portion 32 is attached to the overlapping portions 18 and 19 along the side edges of the cover piece 12 or the vicinity thereof. The connecting portion 32 is mainly provided within the range of the inner surface covering portion 14, but may be provided so as to extend to the side surface covering portions 16 on both sides.

The connecting portions 33 are mainly provided between the side covering portions 16 of adjacent cover pieces 12 or between the side covering portions 16 and 17 of the same cover piece 12 .

The connecting portions 32 and 33 may be of any type as long as they can connect the adjacent cover pieces 12, and may be, for example, a fastener portion or hook-and-loop fastener. In this embodiment, one connecting portion 32 of the connecting portions 32 and 33 is a fastener portion, and the other connecting portion 33 is a hook-and-loop fastener.

The fastener portion is provided at the side edge portion of the cover piece 12 as a connector (connecting member) for connecting at least the inner surface covering portions 14 of the cover piece 12 to integrate them.

The fastener portion mainly has a ribbon tape 32a having a large number of meshing portions called "mushi" along one side edge portion. The fastener portion is a combination of two ribbon tapes 32a and an operating slider 32b for engaging and separating the coupling teeth.

In this embodiment, slider 32b is attached to one ribbon tape 32a. One ribbon tape 32a to which the slider 32b is attached serves as a male fastener, and the other ribbon tape 32a to which the slider 32b is not attached serves as a female fastener. A lead string 32c may be attached to the handle of the slider 32b. It is preferable that the length of the lead string 32c is approximately the same as the short sides 3c, 3d of the base 3 or longer.

The hook-and-loop fastener is used as a connector (connecting member) for connecting and integrating the side covering portions 16 of the adjacent cover pieces 12 and the side covering portions 16 and 17 of the same cover piece 12. , are provided at respective portions of the cover piece 12 .

A hook-and-loop fastener is a flexible surface-fixing member for directly attaching surfaces to each other by a hooking force. There are two types of hook-and-loop fasteners: a first ribbon tape 33a (female) having many loops on its surface and a second ribbon tape 33b (male) having many hooks on its surface. By combining the first ribbon tape 33a and the second ribbon tape 33b one-to-one, a hook-and-loop fastener as a connector is constructed.

The fastener part and the hook-and-loop fastener are sewn at positions overlapping each other between the upper surface of the side edge of the cover piece 12 that is installed earlier and the lower surface of the side edge of the cover piece 12 that is installed later. At this time, the pair of ribbon tapes 32a (male/female) of the fastener part and the ribbon tape 32a and the ribbon tape 32a of the hook-and-loop fastener are separately installed on either the upper surface or the lower surface.

In addition, as shown in FIG. 8, the cover piece 12 may form a fastener cover 35 for covering the connecting portions 32 and 33 from above in the overlapping portion 18 of the overlapping cover piece 12, if necessary. In addition, a backing sheet 36 may be welded to the rear side of the underlying cover piece 12 to cover (the seams of) the mounting portions of the connecting portions 32 and 33 from the rear side. As a result, leakage of rainwater from the connecting portions 32 and 33 can be prevented more effectively.

(A3) As shown in FIG. 8, the cover piece 12 may have a magnet 41 that can be magnetically attracted to the building unit 2 at the side edge.

Here, the magnet 41 is a magnetic body (permanent magnet) that is attracted to metal by magnetic force. The magnet 41 is attracted to the lower side (floor beam 2c) of the metal unit frame that constitutes the building unit 2 and the like. The magnet 41 is installed on the side edge of the cover piece 12 that is covered by the cover piece 12 installed later, or around it.

At this time, the cover piece 12 extends the overlapping portion 19 formed on the side edge portion until it reaches the lower edge portion of the building unit 2 installed at the position of the cover piece 12 installed later. A magnet 41 is attached to the leading edge of the extended overlapping portion 19 or its periphery. The magnet 41 may be sewn or glued to the tip edge of the overlapping portion 19, or the tip edge may be formed into a cylinder and inserted into the interior thereof.

The magnets 41 may be provided at least at the positions of both ends of the inner surface covering portion 14 with respect to the side edges of the cover piece 12, but may be provided continuously or discontinuously along the side edges. . The magnet 41 may be, for example, granular or lumpy, or may be rod-shaped.

(A4) As shown in FIG. 5A (FIG. 5B),
The cover member 11 may be supported in an inclined state with one end side higher than the other end side by a bar member 51 installed on the base 3 (FIG. 6).
The cover piece 12 may be provided with a rod-passing portion 52 (FIG. 8) through which the rod-shaped member 51 is passed.

Here, the cover member 11 may be installed on the foundation 3 using the rod-shaped member 51 so that the inner surface covering portion 14 is in a substantially horizontal state, but the inner surface covering portion 14 may be inclined. It is preferable to install The cover member 11 is inclined from one end side (upper side of the water) toward the other end side (under the water) so as to form a downward slope of at least about the drainage slope or more.

When the cover member 11 is inclined, the width of the side covering portions 16 and 17 is sized to match the inclination of the cover member 11 so that the side covering portions 16 and 17 can cover almost all of the side surfaces of the base 3 or at least the upper portion thereof. to form.

That is, in the cover member 11, the raised side surface covering portion 16 on one end side is made wider than the side surface covering portion 16 on the other end side by the amount to be lifted.

Specifically, as shown in FIG. 6, the width of the side covering portion 16 on the underwater side (or the vertical dimension at the time of installation) is approximately the same as or slightly higher than the height h1 of the foundation 3. is preferred (height h1±α). The width of the side covering portion 16 on the underwater side is at least around the upper portion (top) of the foundation 3, or at least the extent to cover the upper side of the side surface of the foundation 3 (for example, about half or more of h1). It is good enough to be in contact with the ground at most, so it is appropriately set within that range.

Therefore, the width of the side covering portion 16 on the water side is the width of the side covering portion 16 on the water side (height h1±α) plus the height h2 for lifting the water side above the top of the foundation 3. to some extent. As a result, the entire side surface of the foundation 3 or at least the periphery of the upper portion thereof can be covered by the side surface covering portions 16 on the underwater side and the water side without any problem.

Along with this, in order to absorb the difference in the width of the side surface covering portions 16 on the water side and the water side, and to cover at least the upper portions of the side surfaces on the short sides 3c and 3d of the foundation 3 without hindrance. , the side covering portion 17 is trapezoidal (FIG. 7).

The rod-like members 51 are frameworks or support rods attached to the base 3 to keep the cover member 11 in an inclined arrangement with one end higher than the other end and one end higher than the other end. be. A plurality of types of rod-shaped members 51 exist. The rod-shaped member 51 will be described later.

The rod-passing portion 52 is a cylindrical portion through which the rod-shaped member 51 is passed. The rod through portions 52 are attached to and integrated with the cover pieces 12 that constitute the cover member 11 . The rod through portion 52 will be described later. At least one rod through portion 52 is installed, for example, in the vicinity of the position of the connecting portion 32 and the magnet 41 in the cover piece 12 so as to avoid them.

The height h2 from the base 3 on the one end side of the cover member 11 should be higher than the base 3, but is preferably as follows.

(A5) As shown in FIG. 6, the height h2 of one end of the cover member 11 from the foundation 3 may be higher than the carry-in height h3 of the underfloor equipment 61 installed in the foundation 3 .

Here, the underfloor equipment 61 is equipment installed under the floor, and includes, for example, an indoor unit of an air conditioner, an underfloor heating system, and the like.

The carry-in height h3 is the dimension in the vertical direction 4 necessary for the underfloor equipment 61 to pass through. The carry-in height h3 is the sum of the vertical dimension of the underfloor equipment 61 and the required working space. The carry-in height h3 can be set to, for example, 450 mm to 600 mm, preferably about 600 mm.

A rod-shaped member 51 is installed on the water side (long side 3a) of the foundation 3 at an upper position along the long side 3a so as to be higher than the carry-in height h3. The bar member 51 is covered with the cover member 11 from above. As a result, one end side of the cover member 11 installed on the foundation 3 is lifted up to the above height h2, and a work space for carrying in the underfloor equipment 61 is secured between the upper part of the foundation 3 and the rod-shaped member 51. be done. The height h2 described above can be, for example, 600 mm to 800 mm, preferably about 700 mm.

Along with this, the width (or the vertical dimension when installed) of the side surface covering portion 16 on the one end side (the water side) of the cover member 11 is increased by the height h2 which is larger than the dimension of the carry-in height h3. is wider than the width of the side covering portion 16 on the other end side (underwater side).

(Regarding the installation structure of the base cover 8)

The installation structure of the base cover 8 may be any structure, but for example, it is as follows.

(B1) As shown in FIG. 5A (FIG. 5B), the foundation 3 of the building 1 is provided with a foundation cover 8 that covers the foundation 3 from above.
The base cover 8 is held by a bolt member 71 protruding from the base 3 via a mounting bracket 72 or a bar member 51 attached to the mounting bracket 72 .

Here, the installation structure of the base cover 8 is a structure for installing the base cover 8 on the foundation 3 .

For the bolt member 71, for example, it is preferable to use an anchor bolt embedded in (the outer peripheral raised portion) of the foundation 3 so as to protrude upward from the upper portion of the base 3 (the upper surface of the outer peripheral raised portion). However, apart from the anchor bolts, a dedicated bolt member 71 for installing the foundation cover 8 can be attached to the foundation 3 and used. In the case of a unit building, the anchor bolts are installed at least at or near the four corners (columns 2a) of each building unit 2 when the building unit 2 is installed on top of the foundation 3. . Anchor bolts are also appropriately installed at intermediate portions of the short sides 3c and 3d of the foundation 3, and the like.

As shown in FIG. 9 (FIG. 10), the mounting bracket 72 is a metal fitting (supporting rod mounting bracket) that is installed on the bolt member 71 and fixes the rod-shaped member 51 to the bolt member 71. , has a bolt attachment portion 73 that can be attached to the bolt member 71 .

The bolt attachment portion 73 may be, for example, a nut portion 73 a that can be directly screwed onto the bolt member 71 .

The nut portion 73a may be configured by combining a plurality of types of nut members such as a hexagonal nut, a tall nut, and a hexagonal nut.

The mounting bracket 72 has, at least on its upper portion, a clamp portion 74 capable of fixing the rod-shaped member 51 . The clamp portion 74 is attached to the clamp support portion 75 .

The clamp part 74 has, for example, a structure in which one side (upper side) of two half-cylindrical clamp pieces 74a and 74b is connected by a hinge part 74c so as to be openable and closable. The other sides (lower sides) of the clamp pieces 74a and 74b are fixed to the clamp support portion 75 by fastening fixing members 74d such as bolts and nuts. A wing nut (FIG. 10(c)) is preferably used as the nut of the fastening member 74d so that it can be operated by hand.

The mounting bracket 72 has a height setting member 76 interposed between the lower bolt mounting portion 73 and the upper clamp support portion 75 . The height setting member 76 is a member that defines the height of the mounting bracket 72 . For the height setting member 76, for example, a threaded bolt extending in the vertical direction 4 or a rod having threaded portions at both upper and lower ends can be used.

A plurality of types of mounting brackets 72 are used according to the installation position with respect to the foundation 3 . The mounting bracket 72 will be described later.

The rod-shaped member 51 is an elongated rod-shaped member that serves as a framework for keeping the base cover 8 covering the upper portion of the foundation 3 . For the bar member 51, it is preferable to use, for example, a metal hollow pipe member (support pipe) so as to obtain appropriate weight and necessary strength.

A plurality of types of rod-like members 51 are used according to the installation position with respect to the foundation 3 . The rod-shaped member 51 will be described later.

The base cover 8 is indirectly fixed to the base 3 by being connected and fixed to the mounting bracket 72 attached to the bolt member 71 or the rod-shaped member 51 at at least one point. Therefore, a strong fixed state using the foundation 3 can be obtained. However, the base cover 8 may have portions directly fixed to the bolt members 71 .

(B2) The mounting bracket 72 includes a water fitting 81 (FIG. 9) installed on the water side of the foundation 3, an underwater fitting 82 (FIG. 10) installed on the water side of the foundation 3, may be provided.
The water fitting 81 is higher than the water fitting 82 .
The rod-shaped member 51 is arranged along the side on the water side and supported by the water fitting 81 , and is arranged substantially perpendicularly to the water fitting 81 and the water fitting 82 . and a vertical diagonal 84 supported downhill by the .
Further, an upper pressing bar 85 (FIG. 5A) may be provided between the vertical diagonal members 84 and parallel to the vertical diagonal members 84 and placed on the base cover 8 from above.

Here, the side on the water side is one of a pair of parallel long sides 3a and 3b of the foundation 3, and is the long side 3a in this embodiment.

As shown in FIG. 9, the water fitting 81 has two clamps 74 (first clamps portion 86, second clamping portion 87).

The clamp support portion 75 is an L-shaped angle bracket or the like having a horizontal surface 75a and a vertical surface 75b. direction).

The clamp part 74 is attached to the horizontal surface 75a and the vertical surface 75b at different heights.

On the horizontal surface 75a at a lower position, the clamp portion 74 (first clamp portion 86) of the horizontal horizontal member 83 is attached so as to face the extending direction of the horizontal horizontal member 83 (the direction parallel to the long side a of the foundation 3). be done.

A clamp portion 74 (second clamp portion 87) of the vertical diagonal member 84 is attached to the upper portion of the vertical surface 75b higher than the horizontal surface 75a so as to face the direction in which the vertical diagonal member 84 extends.

The position of the lower portion of the first clamp portion 86 (approximately the mounting position with respect to the horizontal horizontal member 83) is set to be at least approximately the same as or slightly higher than the carry-in height h3 of the underfloor equipment 61 described above. The water side portion of the base cover 8 is placed over the vertical diagonal member 84 fixed to the second clamp portion 87 which is higher than the first clamp portion 86 .

A height setting member 76 provided between the lower bolt mounting portion 73 of the water fitting 81 and (the horizontal surface 75a of) the upper clamp support portion 75 is a long strut-like member that defines the height of the water fitting 81. be. The height setting member 76 has its lower end screwed onto (the nut portion 73a of) the bolt mounting portion 73, and its upper end portion is fastened and fixed to the clamp support portion 75 using a hexagonal nut.

The side on the underwater side is the other of a pair of parallel long sides 3a and 3b of the foundation 3, and is the long side 3b in this embodiment.

As shown in FIG. 10, the submerged metal fitting 82 has one clamp portion 74 (third clamp portion 88) capable of fixing the rod-shaped member 51 (vertical diagonal member 84) on its upper portion.

The clamp support portion 75 is an L-shaped angle bracket or the like having a horizontal surface 75a and a vertical surface 75b.

The clamp portion 74 is attached to the upper portion of the vertical surface 75b so as to face the extending direction of the vertical diagonal member 84. As shown in FIG. The portion of the base cover 8 on the underwater side covers the vertical diagonal member 84 fixed to the third clamp portion 88 so as to be slightly higher than the foundation 3 from above the vertical diagonal member 84 .

A height setting member 76 provided between the lower bolt mounting portion 73 of the underwater fitting 82 and the upper clamp support portion 75 (the horizontal surface 75a thereof) is a short strut-like member that defines the height of the underwater fitting 82. is. The height setting member 76 of the underwater fitting 82 is shorter than the height setting member 76 of the underwater fitting 81 (by the amount corresponding to the inclination angle of the vertical diagonal member 84). The clamp support portion 75 of the underwater fitting 82 is supported at a position slightly higher than the upper portion of the foundation 3 by a height setting member 76 . The height setting member 76 has its lower end screwed onto the bolt mounting portion 73 and its upper end fastened and fixed to the clamp support portion 75 using a hexagonal nut.

Since the height setting member 76 of the underwater fitting 82 may be short, the clamp support portion 75 itself may be shaped to extend downward to have the function of the height setting member 76 . For example, the clamp support portion 75 may extend the vertical surface 75 b by the height setting member 76 and directly fix the horizontal surface 75 a to the bolt member 71 . In addition, by arranging the two surfaces of the L-shaped angle metal fitting of the clamp support part 75 in the vertical direction 4 and arranging it with a required length, the clamp support part 75 has the function of mounting the clamp part 74 and high It is possible to combine the function with the thickness setting function.

Furthermore, fixing metal fittings 91 (FIG. 11) may be installed on other sides of the foundation 3 . Other sides are a pair of parallel short sides 3c and 3d of the base 3. As shown in FIG. The fixing bracket 91 is attached to at least one or more or all of the bolt members 71 provided on the short sides 3c and 3d of the foundation 3. As shown in FIG.

The fixing metal fittings 91 are post-shaped metal fittings (cover mounting metal fittings) for fixing the periphery of the side edge of (the inner surface covering portion 14 of) the base cover 8 to the short sides 3c and 3d of the foundation 3. As shown in FIG. The fixing bracket 91 is not the mounting bracket 72 for supporting the rod-shaped member 51 . However, by providing the fixing metal fittings 91, the foundation cover 8 is given tension in the installation direction 13, and the influence of the wind force acting on the vertical diagonal member 84 positioned closest to the short sides 3c and 3d of the foundation 3 is reduced. can be mitigated.

The fixing bracket 91 is, for example, a corner bracket having a substantially triangular shape in a side view, having a horizontal surface 91a, a vertical surface 91b, and a triangular side plate portion 91c. The horizontal surface 91a is strip-shaped and extends in the width direction of the short sides 3c and 3d of the foundation 3. As shown in FIG. The vertical surface 91b has a belt-like shape, and its width direction is oriented in the extension direction of the short sides 3c and 3d of the foundation 3. As shown in FIG. The side plate portion 91c connects one side surface of the horizontal surface 91a and the vertical surface 91b.

A horizontal surface 91 a located at the lower portion of the fixing bracket 91 serves as a bolt mounting portion 73 having a surface (mounting surface) that directly contacts the upper portion of the foundation 3 . A bolt insertion hole 73b is formed in the horizontal surface 91a, and a bolt member 71 can be passed through the bolt insertion hole 73b and fastened and fixed to the foundation 3 with a nut member from above.

A height adjusting plate 92 is attached to the upper portion of the vertical surface 91b so as to be slidable in the vertical direction 4. As shown in FIG. The height adjustment plate 92 is a rectangular plate member that has substantially the same width as the vertical surface 91b and extends in the vertical direction 4, and has a surface parallel to the vertical surface 91b. The height adjustment plate 92 is adjusted to a height corresponding to its installation position so that it is at the same height as or slightly lower than the portion of the vertical diagonal member 84 adjacent to the fixture 91 .

The vertical surface 91b and the height adjustment plate 92 are formed with bolt insertion holes 94a and 94b for passing fastening fixtures 93 such as bolts and nuts, respectively. be.

At least one of the bolt insertion holes 94a and 94b is an elongated hole extending in the vertical direction 4. As shown in FIG. In this embodiment, the elongated holes are the bolt insertion holes 94b of the height adjustment plate 92. As shown in FIG. The height adjustment plate 92 has a mounting hole 92a for mounting the base cover 8 on its top.

The base cover 8 is attached to the upper end portion (mounting hole portion 92a of the height adjustment plate 92) of the fixing bracket 91 with a string-like member 21 such as a band using the mounting hole 22 of the mounting auxiliary portion 23 (string threading piece). It is fixed (for example, FIG. 19(b)). Therefore, the auxiliary attachment portion 23 and the attachment hole 22 are at least positioned near the upper end portion of each height adjustment plate 92 in the base cover 8 and each bolt member 71 (in the direction of the long sides 3a and 3b of the base 3, position close to the direction of the short sides 3c and 3d).

A horizontal horizontal member 83 and a vertical diagonal member 84 as the rod-shaped members 51 are attached to the foundation 3 and serve as a main framework for supporting the foundation cover 8 from below. The "horizontal" of the horizontal horizontal member 83 and the "vertical" of the vertical diagonal member 84 refer to the directions of the long sides 3a, 3b and the short sides 3c, 3d when the upper part of the foundation 3 is viewed in plan. is.

The horizontal horizontal member 83 is a rod-shaped member 51 that connects and integrates the upper parts of the water fittings 81 . The horizontal horizontal members 83 are installed between the plurality of water fittings 81 so that the intermediate portions other than both ends are substantially out of contact with the base cover 8 . The horizontal horizontal member 83 has approximately the same length as the waterside side (long side 3a) of the foundation 3, and is located at a high position above (directly above or in the vicinity of) the waterside side (of the foundation 3). It is installed substantially horizontally at a position higher than the upper part by the carry-in height h3 of the underfloor equipment 61 described above. The lateral horizontal members 83 are attached so that both ends slightly protrude from the clamp portions 74 of the water fittings 81 located on the outermost side. Thereby, the base cover 8 can be expanded in the direction of the long sides 3 a and 3 b of the base 3 .

The vertical diagonal members 84 are rod-shaped members 51 that directly support the base cover 8 from below. The vertical diagonal member 84 has a length that is substantially the same as the pair of short sides 3c and 3d of the foundation 3 (or longer than the short sides 3c and 3d by the amount of inclination). One or more vertical diagonal members 84 are located above (directly above or in the vicinity of) the short sides 3c and 3d and at appropriate positions inside the foundation 3. is installed in In the case of a unit building, the vertical diagonal members 84 inside the foundation 3 are installed one by one in the vicinity of the positions that are substantially the boundaries 31 between the building units 2 adjacent to each other. The vertical diagonal members 84 are attached so that both ends slightly protrude from the clamp portions 74 (the second clamp portion 87 and the third clamp portion 88) of the water fitting 81 and the water fitting 82, respectively. Thereby, the base cover 8 can be expanded in the direction of the short sides 3c and 3d of the base 3. As shown in FIG.

The upper pressing bar 85 is a frame (middle frame) placed on the base cover 8 to hold down the base cover 8 from above. The upper pressing bar 85 is not used as a framework for supporting the base cover 8 from below and is not directly connected to other frameworks. Therefore, although the upper pressing bar 85 is detached from the rod-like member 51 in a narrow sense, it supports the base cover 8 as a whole, so in a broad sense it can be included in the rod-like member 51 as part of the framework.

The upper pressing bar 85 has approximately the same length as the vertical diagonal members 84 and is installed approximately in parallel with the vertical diagonal members 84 at approximately the middle position between the adjacent vertical diagonal members 84 . In the case of a unit building, the upper pressing bar 85 is installed at a position near the center of the width of each building unit 2 . In this embodiment, the upper pressing bar 85 is installed so that one end is positioned above the horizontal horizontal member 83 and the other end is positioned above the water side (long side 3b) of the foundation 3. .

By installing the upper pressing rod 85, the weight of the upper pressing rod 85 causes the entire position of the upper pressing rod 85 to be recessed, thereby forming a downward-sloping drainage groove 89 (FIG. 8). be done.

The other end of the upper presser bar 85 may be directly grounded to the upper surface of the long side 3b by being lower than the other end of the vertical diagonal member 84 (approximately 200 mm in height). It may be in a state of slightly floating from the long side 3b.

At this time, the base cover 8 has a mountain-and-valley shape with the position of the vertical diagonal member 84 as the top of the mountain and the position of the upper pressing bar 85 as the bottom of the valley. will be pulled to In addition, by setting the connecting portion 32 between the cover pieces 12 at a relatively high position near the peak between the peak (vertical diagonal member 84) and the valley (upper pressing bar 85), rainwater can be prevented from the connecting portion 32. becomes difficult to enter. In this embodiment, the connecting portion 32 is provided at a position slightly closer to the short side 3 d than the vertical diagonal member 84 .

The horizontal horizontal member 83, the vertical oblique member 84, and the upper pressing bar 85 can all have the same diameter and thickness. You can allow it. In this embodiment, the vertical diagonal member 84, which directly supports the base cover 8 and requires the highest strength, has the largest diameter and the largest wall thickness. The upper presser bar 85, which is placed on the base cover 8 and does not require much strength, has the smallest diameter and the thinnest wall. The horizontal horizontal member 83 has the same diameter as the vertical diagonal member 84 or has an intermediate diameter and thickness between the vertical diagonal member 84 and the upper pressing bar 85 .

(B3) As shown in FIG. 12, the rod member 51 may be adjustable in length.

Here, "adjustable length" means that the length can be changed. The rod-shaped member 51 may be one whose length cannot be adjusted, but it is preferable that the length is adjustable. For length adjustment, the rod-shaped member 51 may, for example, consist of a plurality of short metal pipe pieces 51a and a metal threaded joint 51b.

In this case, the rod-shaped member 51 is made to have a desired length by connecting a plurality of short pipe pieces 51a with a threaded joint 51b. Conversely, by removing the pipe piece 51a at the position of the threaded joint 51b, the bar member 51 is disassembled into a plurality of short pipe pieces 51a. The pipe pieces 51a may all have the same length, or different lengths may be mixed. If all the pipe pieces 51a have the same length, the length of the rod-shaped member 51 is an integral multiple of the length of one pipe piece 51a.

The pipe piece 51a has a male screw portion 51c on the outer peripheral surface of both ends. The threaded joint 51b is a single tubular member having an inner diameter that can be fitted onto the end of the pipe piece 51a, and has a female threaded portion 51d to which the male threaded portion 51c can be screwed on its inner peripheral surface.

The threaded joint 51b may be configured as a separate member from the pipe piece 51a, or may be fixed to one end of the pipe piece 51a and integrated with the pipe piece 51a.

At least one of the horizontal horizontal member 83, the vertical diagonal member 84, and the upper presser bar 85 may be adjustable in length, but it is preferable to make all of them adjustable in length. FIG. 12 shows an example of the vertical diagonal member 84, but the horizontal horizontal member 83 and the upper pressing bar 85 can also be provided with a similar length adjusting structure (or connecting structure).

Specifically, in the case of a unit building, the main pipe piece 51a that constitutes the horizontal horizontal member 83 is preferably formed to have a length that is an integer fraction of the short side of the building unit 2 .

In addition, in the case of a unit building, the main pipe piece 51a that constitutes the vertical diagonal member 84 and the upper pressing bar 85 is preferably formed to have a length that is an integer fraction of the long side of the building unit 2. As shown in FIG.

The pipe pieces 51a forming the vertical oblique member 84 and the upper pressing bar 85 may have any length, but may be made to have the same length as the pipe pieces 51a forming the horizontal horizontal member 83. However, the horizontal horizontal member 83, the vertical diagonal member 84, and the upper pressing bar 85 may have pipe pieces 51a having different lengths.

In addition, the length adjustment mechanism of the rod-shaped member 51 is not limited to the above. For example, various joint structures other than the screw type joint 51b, splicing structures using spigot joints, telescoping structures using nested multiple cylinders, etc. are adopted. You can However, in terms of strength, it is most preferable to use the screw joint 51b in order to secure the required wind resistance. Also, structurally, the screw type joint 51b is preferable because it is the simplest.

(B4) The rod-shaped member 51 may be installed through a rod-passing portion 52 (FIG. 12) provided in the base cover 8 .

Here, the rod-passing portion 52 is a cylindrical portion through which the rod-shaped member 51 is passed, and at least one rod-passing portion 52 is provided on the base cover 8 . The rod through portion 52 preferably has a diameter slightly larger than that of the rod-shaped member 51 and is preferably a cylindrical body having a length substantially equal to or slightly shorter than that of the rod-shaped member 51 . The rod through portion 52 is preferably made of substantially the same material as the base cover 8 . The rod through portion 52 is attached to the installation position of the rod-shaped member 51 in the base cover 8 so as to extend continuously in the installation direction of the rod-shaped member 51 .

The foundation cover 8 may be a single large-sized one that can cover the entire foundation 3 at the same time. is preferably divided into In this case, at least one rod through portion 52 is provided for each cover piece 12 (FIG. 7). In this embodiment, each cover piece 12 is provided with a bar through portion 52 through which a vertical diagonal member 84 and an upper pressing bar 85 are passed and fixed.

Although the rod through portion 52 for the horizontal horizontal member 83 is not provided, the rod through portion 52 for the horizontal horizontal member 83 can be provided as required.

(B5) As shown in FIG. 7 (FIG. 8), the rod through portion 52 is
a lower surface side through portion 52a provided on the lower surface side of the base cover 8;
and an upper surface side through portion 52b provided on the upper surface side of the base cover 8 may be provided.
As shown in FIG. 8, the vertical diagonal member 84 may be installed on the lower surface side of the base cover 8 through the lower surface side through portion 52a.
The upper pressing bar 85 may be installed on the upper surface side of the base cover 8 through the upper surface side through portion 52b.

Here, the lower-surface-side through portion 52 a is for holding and fixing the rod-shaped member 51 to the base cover 8 by passing the rod-shaped member 51 (vertical diagonal member 84 ) under the base cover 8 . The lower surface side through portion 52a is attached to the lower surface side of the base cover 8 by sewing, welding, or the like. The lower surface side through portion 52 a is provided at a position between the second clamp portion 87 of the water fitting 81 and the third clamp portion 88 of the water fitting 82 in the inner surface covering portion 14 of the cover piece 12 . The lower surface side through portion 52a is formed to have a length substantially equal to or shorter than the distance between the second clamp portion 87 and the third clamp portion 88. As shown in FIG.

The upper surface side through portion 52b is for holding and fixing the rod-shaped member 51 to the base cover 8 by passing the rod-shaped member 51 (upper pressing rod 85) through the upper side of the base cover 8. As shown in FIG. The upper surface side through portion 52b is attached to the upper surface side of the base cover 8 by sewing, welding, or the like. In addition, the upper surface side through portion 52b is formed in the inner surface covering portion 14 of the cover piece 12 so as to be substantially the same as or shorter than the short sides 3c and 3d of the base 3. As shown in FIG.

When the base cover 8 is divided into cover pieces 12 each having a size for each unit building, each cover piece 12 has at least one vertical diagonal member 84 and one upper pressing bar 85 passing therethrough. Two through parts 52 are provided in total.

The two rod through portions 52 are installed at one side edge of the cover piece 12 (on the side of the short side 3c of the base 3) and at the center of the width (or in the vicinity thereof). The rod-passing portion 52 on one side edge serves as a lower surface-side passing portion 52a through which a vertical diagonal member 84 is passed. The rod-passing portion 52 at the center of the width serves as a top-side passing portion 52b, through which the upper presser bar 85 is passed. However, for the cover piece 12 that is installed first, the other side edge (on the short side 3d side of the foundation 3) also has a bar through portion 52 for the vertical oblique member 84 near the short side 3d of the foundation 3 ( A lower surface side through portion 52a) is provided.

The installation structure of the foundation cover 8 described above can be applied not only to the foundation 3 of the unit building but also to the foundation 3 of a general building 1.

The installation method of the basic cover 8 based on the installation structure of the basic cover 8 is as follows.

(B1) As shown in FIG. 5A (FIG. 5B), the foundation 3 of the building 1 is covered with a foundation cover 8 from above. At this time, the base cover 8 is held (to the base 3 ) by bolt members 71 projecting from the base 3 via mounting brackets 72 or rod-shaped members 51 attached to the mounting brackets 72 .

(B2) As the mounting bracket 72, a water fitting 81 (FIG. 9) is installed on the water side of the foundation 3, and a water fitting 82 (FIG. 10) lower than the water fitting 81 is installed on the water side of the foundation 3. ). As the rod-shaped member 51, a horizontal horizontal member 83 is arranged along the water side and supported by the water fitting 81, and a vertical diagonal member 84 substantially perpendicular to the horizontal horizontal member 83 is attached to the water fitting 81 and the water fitting. Support downhill by 82 . The base cover 8 obliquely covers the base 3 from above (installed in an inclined state) so that the water side is raised and the water side is lowered by the mounting bracket 72 and the rod member 51 . Then, an upper pressing bar 85 (FIG. 5A) parallel to the vertical diagonal members 84 is placed on the base cover 8 from above at a position between the vertical diagonal members 84 to form a drainage groove 89 in the base cover 8 .

(B3) As shown in FIG. 12, a member whose length can be adjusted is used as the rod-like member 51 . The rod-like member 51 is attached to the foundation 3, the foundation cover 8, etc., or detached, while adjusting the length, depending on the situation.

(B4) The rod-like member 51 is passed through the rod-passing portion 52 (FIG. 12) provided in the base cover 8 and installed.

(B5) At this time, as shown in FIG. 7 (FIG. 8), the rod passing portion 52 is divided into a lower side passing portion 52a provided on the lower side of the base cover 8 and an upper side passing portion 52a provided on the upper side of the base cover 8. It is referred to as a through portion 52b. As shown in FIG. 8, the vertical diagonal member 84 is installed on the lower surface side of the base cover 8 through the lower surface side through portion 52a. The upper pressing bar 85 is installed on the upper surface side of the base cover 8 through the upper surface side through portion 52b.

Moreover, the method of putting away the building 1 with a drizzle using the base cover 8 is as follows.

(A1) The foundation 3 of the building 1 is covered with the cover member 11 from above. At this time, the cover member 11 is divided and a plurality of cover pieces 12 matching the size of the building unit 2 are provided. Alternatively, the cover member 11 is composed of a plurality of cover pieces 12 formed according to the size of the building unit 2. - 特許庁A plurality of cover pieces 12 are installed side by side on the foundation 3 according to the arrangement (installation position) of the building unit 2 (relative to the foundation 3).

(A2) As shown in FIG. 7, a connection in which cover pieces 12 (a plurality of cover pieces 12 are arranged side by side on the foundation 3) are provided at the side edges located at the boundaries 31 (for example, FIG. 3) between the building units 2. The parts 32 and 33 are connected to each other. Thereby, the cover piece 12 becomes the integrated cover member 11 .

(A3) As shown in FIG. 8, the cover piece 12 is magnetically attracted to the building unit 2 by the magnets 41 provided on the side edges. As a result, the gap between the side edge of the cover piece 12 and the building unit 2 is eliminated to prevent rainwater from entering through the gap.

(A4) When installing the cover piece 12 on the foundation 3, as shown in FIG. 5A (FIG. 5B), the cover member 11 is tilted so that one end is higher than the other end by means of a bar member 51 installed on the foundation 3. Support (Fig. 6). Then, the rod-shaped member 51 is passed through the rod-passing portion 52 ( FIG. 8 ) provided in the cover piece 12 . Alternatively, the rod-like member 51 is held by the cover piece 12 by passing it through the rod-passing portion 52 .
(A5) At this time, as shown in FIG. 6, the height h2 of one end of the cover member 11 from the foundation 3 is made higher than the carry-in height h3 of the underfloor equipment 61 installed in the foundation 3 .

(A6) In the above, when the building units 2 are installed in order on the foundation 3, the cover member 11 floats the building unit 2 to be installed above the foundation 3. The cover piece 12 positioned below 2 is removed (eg, by turning over). This prevents rainwater from entering the foundation 3 through the portion where the cover piece 12 is removed.

(A7) After installing the building unit 2 at the position from which the cover piece 12 has been removed, the side edge of another cover piece 12 adjacent to the removed cover piece 12 is pulled by the magnet 41 provided on the side edge. It is magnetically attracted to the installed building unit 2 .

(A8) The cover piece 12 is provided with overlapping portions 18 and 19 on the side edges thereof. Then, the cover piece 12 is placed on the foundation 3 from the later side of the installation order of the building unit 2 to the earlier side while overlapping the side edge portion (overlapping the overlapping portion 18 on the overlapping portion 19). installed in order. On the contrary, the cover pieces 12 are removed from the foundation 3 in order from the early side to the late side of the installation order of the building unit 2. - 特許庁

(A9) Then, when installing the building unit 2 on the foundation 3, the upper surface of the building unit 2 is (preliminarily) covered with the temporary rain cover sheet 7, and another building unit 2 is placed next to the building unit 2. is installed, the temporary rain finishing sheets 7 on the upper surfaces of the building units 2 adjacent to each other are connected to each other.

(A10) When the building unit 2 of the upper floor H is installed on the building unit 2, the temporary rain cover sheet 7 covering the upper surface of the building unit 2 is used to cover the building unit 2 of the upper floor H above the building unit 2. Remove (by turning over) the temporary rain sheet 7 positioned under the floating building unit 2 on the upper floor H.

(A11) Form the side upper cover part 7a which covers the upper part of the side surface of the building unit 2 in the temporary rain cover sheet 7. As shown in FIG. Then, the adjacent drizzle sheets 7 connect the upper side cover portions 7a with the upper side cover portions 7a bent upward, and the connected upper side cover portions 7a are doubled in the connected state. Bend it once.

(A12) As described above, the bolt member 71 protruding from at least the side (long side 3a) on the water side of the foundation 3 of the unit building (building 1) is attached to the water side via the water metal fitting 81. A horizontal horizontal member 83 extending along the side (long side 3a) is attached. A foundation 3 on which a horizontal member 83 is installed so as to be higher than the water side (long side 3a) is obliquely covered from above with a foundation cover 8. - 特許庁The peripheral edge of the base cover 8 is fixed to the ground by a string-like member 21 or a peg 24, and is also fixed to a bolt member 71 projecting from the base 3 or to a fixture 91 attached to the bolt member 71. - 特許庁In this state, in the method of removing the foundation cover 8, immediately before installing the first building unit 2 on the foundation 3, the string-like members 21, the pegs 24, the fixtures 91, and the lateral horizontal members 83 are first removed from the building. Remove the part where the unit 2 is installed.

Hereinafter, more specific methods of using the base cover 8 will be described separately for the installation method and the removal method.

(Regarding how to install the base cover 8)

A foundation cover 8 is installed on the foundation 3 so as to cover the entire foundation 3. - 特許庁The work flow at that time will be described.

First, as shown in FIG. 13, mounting brackets 72 and the like are attached to the bolt members 71 of the foundation 3 (mounting bracket installation step).

At this time, a water fitting 81 is attached to the water side (long side 3a) of the foundation 3, and a water fitting 82 is attached to the water side (long side 3b). In addition, fixing metal fittings 91 are attached to other sides (short sides 3c and 3d). The fixing bracket 91 is adjusted to a height approximately equal to the portion near the vertical diagonal member 84 . Adjustments may be made at the time of installation or after the vertical diagonals 84 are installed.

In the case of a unit building, the bolt members 71 (anchor bolts) are installed at least at the four corners of the building unit 2 or in the vicinity of the positions where the building units 2 are installed on the foundation 3 . Therefore, at the position of the boundary 31 of the adjacent building unit 2, two bolt members 71 for the adjacent building unit 2 are installed side by side relatively close to the long sides 3a and 3b of the foundation 3. be. In this case, the mounting bracket 72 (the underwater bracket 82 and the underwater bracket 81) is attached to either one of the two bolt members 71. As shown in FIG.

In this embodiment, of the four bolt members 71 provided at the installation position of each building unit 2 with respect to the foundation 3, the bolt member 71 is located on the earlier side of the installation order of the building unit 2 (in this embodiment, on the side of the short side 3c). The mounting bracket 72 is attached to the two bolt members 71 to be connected. The remaining two bolt members 71 are basically not attached with the fittings 72 . Therefore, of the two bolt members 71 installed side by side at the position of the boundary portion 31, the one positioned on the short side 3d side is used for mounting the mounting bracket 72. As shown in FIG.

As for the position of the building unit 2 whose installation order is the last, the mounting brackets 72 are attached to all the bolt members 71 at the four corners.

The mounting metal fittings 72 are mounted by making a pair of the water metal fittings 81 and the water metal fittings 82 .

Then, using the mounting bracket 72 attached to the bolt member 71, the rod-shaped member 51 is installed above the foundation 3 (first support rod installation step).

First, the horizontal horizontal members 83 are installed substantially horizontally between the upper ends of the water fittings 81 , and all the water fittings 81 are connected by the horizontal horizontal members 83 . The horizontal horizontal member 83 may be installed after being connected and lengthened in advance, or may be installed while being connected and lengthened. The horizontal horizontal member 83 is installed at a relatively high position above the water side of the foundation 3 .

After the horizontal horizontal member 83 is installed above the foundation 3, the foundation cover 8 is put on the horizontal horizontal member 83 to cover the foundation 3, as shown in FIG. As a result, the base cover 8 is held in shape by the both ends of the horizontal members 83 so that the water side can extend in the extending direction of the long side 3 a of the base 3 to cover the short sides 3 c and 3 d of the base 3 .

At this time, the base cover 8 is installed so that one side of the base 3 can be covered with the inner surface covering portion 14 and the long sides 3 a and 3 b of the base 3 can be covered with the side covering portion 16 . The first and last cover pieces 12 are installed in such a manner that the short sides 3c and 3d of the foundation 3 can be covered with the side covering portions 17. As shown in FIG.

The base cover 8 may be installed in a state in which a plurality of cover pieces 12 are connected in advance and enlarged. Alternatively, as shown in FIG. The cover pieces 12 may be connected together by connecting portions 32 and 33 later to increase the size.

When connecting the cover pieces 12 later, the cover pieces 12 are installed in order from the later side of the building unit 2 (in this embodiment, the side of the short side 3d of the foundation 3) to the earlier side. . The cover pieces 12 are installed one by one in order so that part of the adjacent side edge (overlapping portion 18) overlaps on the side edge (overlapping portion 19) of the previously installed cover piece 12. (See Figure 8).

Each time the cover piece 12 is installed, the vertical diagonal member 84 is passed through the bar through portion 52 (lower surface side through portion 52a) to integrate the vertical diagonal member 84 and the cover piece 12 into one. A material 84 keeps one side edge straight and taut. Both ends of the vertical diagonal member 84 are fixed to the water fitting 81 and the water fitting 82 to support the vertical diagonal member 84 downward. As a result, the water side and the water side of the portion (inner surface covering portion 14) covering the inside of the foundation 3 of the cover piece 12 are expanded in the extending direction of the short sides 3c and 3d by the both ends of the vertical diagonal member 84. .

As described above, the cover piece 12 spreads in a downwardly inclined state from the water side to the water bottom side, and a prototype of a shape in which rainwater does not accumulate on the cover piece 12 is formed (second support rod installation step). .

Note that the cover piece 12 may be installed on the foundation 3 in order after the vertical diagonal members 84 are first passed through the rod-passing portion 52 (lower side passing portion 52a). As a result, when the cover piece 12 is turned upside down so that the lower surface faces upward, the vertical oblique member 84 can be passed through the rod threading portion 52 which has been turned upward, so that the workability of threading the rod can be improved. can.

The vertical diagonal member 84 may be connected in advance and lengthened, and then passed through the rod through portion 52 (lower side through portion 52a) and fixed at both ends to the water fitting 81 and the water fitting 82, or may be made long by being connected. Both ends may be fixed to the water fitting 81 and the water fitting 82 by passing through the rod through portion 52 .

Then, when all the cover pieces 12 installed on the foundation 3 are fixed through the vertical diagonal member 84, the adjacent cover pieces 12 are connected by the connecting portions 32 and 33 at the overlapped portions of the side edges of the adjacent cover pieces 12, as described above. Connect and unify. This makes it difficult for rainwater to leak from between the side edges of the adjacent cover pieces 12 .

When the connecting part 32 is a fastener, the fastener is attached to one side (for example, the underwater side) of the cover piece 12, and the lead string 32c is pulled from the other side (for example, the underwater side). As a result, the cover piece 12 (the inner surface covering portion 14 thereof) is connected by the fastener without entering the foundation 3 . It is preferable to return the tip of the lead string 32c to one side (for example, the underwater side) after the connection.

In addition, when the connecting portion 33 is a hook-and-loop fastener, the hook-and-loop fastener is joined simply by overlapping the side edges of the adjacent cover pieces 12 (the side covering portions 16 thereof) and pressing them from above. The connection portion 33 (hook-and-loop fastener) between (the side covering portion 16 and the side covering portion 17 of) the same cover piece 12 is similarly connected at an appropriate timing.

As shown in FIGS. 16 and 17, after connecting the cover pieces 12 to form one base cover 8, an upper pressing bar 85 is installed on the base cover 8 (third support bar installation step). In this embodiment, the upper pressing bar 85 is inserted from above the water to below the water, but it may be inserted from either side.

The upper presser bar 85 may be connected and lengthened in advance and then passed through the bar passing portion 52 (upper side passing portion 52b). Also good. As a result, the upper pressing bar 85 and the cover piece 12 are integrated.

The upper pressing bar 85 has its water side end positioned above the horizontal horizontal member 83 and its water side end positioned above the upper surface of the foundation 3 (the long side 3b thereof).

By placing the upper pressing bar 85 on the cover piece 12 in this way, the cover piece 12 is dented downward by the weight of the cover piece 12, and as shown in FIG. 18 from the state shown in FIG. becomes a steep downward slope.

At this time, the cover piece 12 is pressed from above by the weight of the upper pressing rod 85, and is recessed downward around the position of the upper pressing rod 85, increasing the overall tension. In particular, the underwater side of the cover piece 12 is held at the upper end of the underwater fitting 82 by a vertical diagonal member 84, and is lowered by an upper pressing rod 85 to a position above or slightly above the foundation 3. Since it is lower than the lower metal fitting 82, it has a relatively large mountain-valley shape.

As a result, the cover piece 12 is formed with a downward-sloping drainage groove 89 along the upper pressing bar 85 between the vertical diagonal members 84 . This drainage groove 89 gradually becomes larger and deeper from the water side toward the water side.

Then, as shown in FIG. 19, while checking and adjusting the tension of the base cover 8, each part (the position of the mounting hole 22) of the peripheral edge of the base cover 8 is tightened with a string-like member 21 such as a band. , the mounting metal fittings 72, the fixing metal fittings 91, the bolt members 71 of the foundation 3, and the like.

When the bar member 51 and the upper pressing bar 85 are fixed to the base cover 8, they may be bound by directly winding a string member 21 such as a band. Also, as shown in FIG. 17B, a cap 95 having a through hole 95a is attached to the end of the rod-like member 51, and the through hole provided in the cap 95 is used to attach the string-like member 21 such as a band to the base. It may be passed through the mounting hole 22 of the cover 8 and fixed.

Further, the peripheral edge of the base cover 8 may be supplementarily fixed to the ground using a string member 21 such as a band and a peg 24 so that the peripheral edge of the base cover 8 is not flapped by the wind. The peg 24 is driven in at a position as close to the base 3 as possible.

Finally, it is preferable to perform a water resistance test by pouring water over the base cover 8 .

Installation of the foundation cover 8 to the foundation 3 is completed by the above. By firmly fixing the base cover 8 to the bolt members 71 of the base 3 via the mounting brackets 72 and the rod-like members 51, the base cover 8 can be reliably prevented from being blown away by the wind.

(How to remove the base cover 8)

Next, how to install the building unit 2 on the foundation 3 when it rains and how to remove the foundation cover 8 at that time will be described.

Normally, the building unit 2 is not installed on the foundation 3 when it rains, but in this embodiment, the building unit 2 can be installed even when it rains.

Before installing the building unit 2, make sure that the foundation cover 8 is free of rainwater. When rainwater is accumulated on the base cover 8, the accumulated rainwater is forcibly drained by, for example, a pump (rainwater removal step).

First, string-like members 21 such as bands and pegs 24 that are fastened to the ground, bolt members 71, fixing metal fittings 91, mounting metal fittings 72, etc., and rod-like members 51, etc., are removed from the peripheral portions of the base cover 8. By removing it, the peripheral portion of the base cover 8 is released from the lashing state (peripheral portion releasing step). When it is not raining, the entire base cover 8 can be removed at once. This work is done just before installing the first building unit 2 on the foundation 2 . "Just before the first building unit 2 is installed" generally refers to the period from before and after the arrival of the first building unit 2 to the construction site on the day of installation until the first building unit 2 is lifted onto the foundation 2. is preferred.

Then, the building units 2 are sequentially installed one by one in the installation direction 5 from the short side 3c side toward the short side 3d side with respect to the foundation 3. As shown in FIG. At this time, as shown in FIG. 20, only the upper pressing bar 85 and the rod-shaped member 51 (a part of the horizontal horizontal member 83 and the vertical diagonal member 84) installed at the position where the building unit 2 is installed on the foundation 3 are removed. Remove from base 3. Also, the mounting metal fittings 72 (underwater metal fittings 82 and water metal fittings 81) installed in that portion are also removed from the foundation 3. If there is a fixing metal fitting 91 in that portion, the fixing metal fitting 91 is also removed (partial removal step of rod-shaped member, etc.). As for other parts of the foundation 3, the rod-shaped member 51, the mounting bracket 72, etc. are still left.

At this time, the upper pressing rod 85 is completely pulled out from the rod passing portion 52 . The upper presser bar 85 may be removed by pulling out the whole from the bar through portion 52 (upper side through portion 52b) at once. Also, the upper pressing bar 85 may be pulled out from the bar through portion 52 while removing the threaded joint 51b and disassembled into short pipe pieces 51a. It should be noted that it is not necessary to disassemble the upper pressing rod 85 into individual pipe pieces 51a. It is most efficient to disassemble the upper pressing rod 85 into lengths that do not protrude from the premises, and the work can be completed in a short period of time. (The same applies to other rod-shaped members 51).

As for the vertical diagonal member 84, if it is removed from the mounting bracket 72 (underwater bracket 82, above water bracket 81), it will be removed from the foundation 3. You can leave it.

The horizontal horizontal member 83 may be removed in any way as long as only the portion where the building unit 2 is installed can be removed. The horizontal horizontal member 83 is, for example, disassembled at one threaded joint 51b between the removed portion and the remaining portion, and the removed portion is placed on the earlier side of the building unit 2 in the order of installation (in this embodiment, the shorter side). 3c side)). On the other hand, for example, at the position on the later installation order side of the building unit 2 (in this embodiment, on the side of the short side 3d), horizontal horizontal members are installed by the length of one short side 3c, 3d of the building unit 2. 83 may be pulled out. On the side of the short side 3d, the portion of the horizontal horizontal member 83 pulled out from the mounting bracket 72 (water fitting 81) is disassembled into pipe pieces 51a and removed. In this case, the clamp portions 74 of all the water fittings 81 are loosened so that the lateral horizontal members 83 can slide within the clamp portions 74 . Alternatively, after disassembling at one screw joint 51b between the part to be removed and the part to be left, disassemble at one screw joint 51b located in the middle of the part to be removed to divide the part to be removed into two parts. may be pulled out toward the inside. The horizontal members 83 are left as they are on the foundation 3 in the portion where the building unit 2 is not yet installed.

Then, the mounting bracket 72 and the fixing bracket 91 from which the rod member 51 is removed are removed from the bolt member 71 and collected as described above.

In such a state, the building unit 2 is lifted by a crane, and as shown in FIG. (partial removal process for rod-like members, etc.). The building unit 2 is made to float at a height suitable for removing the cover piece 12, neither too high nor too low.

In this state, only the cover piece 12 under the raised building unit 2 is turned over toward the short side 3d of the foundation 3, and the base cover 8 is temporarily placed so as to overlap the adjacent cover piece 12. (Cover piece removing step). Then, as shown in FIG. 21(b), the building unit 2 is installed (building unit installation process).

At this time, the magnets 41 attached to the side edges (or overlapping portions 19) of the adjacent cover pieces 12 on the building unit 2 side are attached to the bottom (floor beams 2c of) of the installed building unit 2, and the building unit is assembled. 2 and the side edges of the adjacent cover pieces 12 are quickly closed (side edge suction step). The magnet 41 is attached at a position higher than the vertical diagonal member 84 .

After installing the building unit 2 in this manner, preparations for installing the next building unit 2 are made. In the meantime, as shown in FIG. 22A(a), the connecting portions 32 and 33 between the cover piece 12 that has been turned over and the adjacent cover piece 12 are removed, and the cover piece 12 that has been turned over is separated from the adjacent cover piece 12. (cover piece separation step). Adjacent cover strips 12 are left intact on the foundation 3 .

When the connecting part 32 is a fastener, the fastener is removed without entering the foundation 3 by pulling the lead string 32c from one side (for example, the underwater side) of the cover piece 12, and the flipped cover piece 12 is removed. separated.

Also, when the connecting portion 33 is a hook-and-loop fastener, the side edge portions of the cover piece 12 (the side covering portions 16 thereof) are peeled off. Note that the hook-and-loop fastener of the side covering portion 16 may be peeled off when the cover piece 12 is turned over.

If the vertical diagonal member 84 is left in the rod-passing portion 52 of the cover piece 12 that has been turned over, as shown in FIG. After that, the vertical oblique member 84 is pulled out from the bar through portion 52 of the cover piece 12 . In this embodiment, the vertical diagonal members 84 are pulled out to the underwater side, but they may be pulled out to either side. The method of pulling out the vertical diagonal member 84 is the same as that of the upper pressing bar 85 described above. The reason why the vertical diagonal member 84 is left on the cover piece 12 until the cover piece 12 is turned over is that the cover piece 12 can be quickly and neatly turned over by holding the vertical diagonal member 84 and operating it.

After the cover pieces 12 are separated and the vertical diagonal members 84 are removed, as shown in FIG. 22B, the cover pieces 12 are folded over the rest of the base cover 8 and rolled up to be collected (cover piece collection step). .

After that, the above is performed in order until the installation of all the building units 2 on the lower floor L is completed.

As described above, the building unit 2 on the lower floor L can be installed without wetting the inside of the foundation 3 even when it rains, and the foundation cover 8 can be removed from the foundation 3 in a well-organized manner.

The connection and detachment of the temporary rain cover sheet 7 will be described below.

(Regarding the connection of the sheet 7 after drizzle)

Next, when installing the building unit 2 of the lower floor L adjacently on the foundation 3, the adjacent side upper part of the temporary rain finishing sheet 7 attached (in advance) to the upper surface of the building unit 2 of the lower floor L The cover portions 7a (FIG. 23A(a)) are respectively bent upward (FIG. 23A(b)), and the back surfaces of the upper side cover portions 7a are brought together and connected by the second connecting portion 7c (side surface Upper cover portion connecting step, FIG. 23B(a)).

The connected upper side cover portion 7a is folded in half at the position of the folding auxiliary line portion 7d so that the upper edge of the upper side cover portion 7a faces downward and is hidden inside the folded upper side cover portion 7a ( Double-folding step, FIG. 23B(b)). This prevents rainwater from entering between the upper side cover portions 7a from the (upper) edges of the upper side cover portions 7a.

Then, the side upper cover portion 7a that has been folded in half is brought down to the side of the adjacent temporary rain sheet 7 so that it is laid down (FIG. 23C(a)). The laid side upper cover portion 7a is fixed to a scaffold or the like using a binding member such as a band as necessary (FIG. 23C(b)).

After that, the above is repeated until all the building units 2 of the lower floor L are installed on the foundation 3 . As a result, all the sheets 7 for finishing with a drizzle are connected and integrated, and the upper surface of the building unit 2 on the lower floor L is finished with a drizzle.

(Regarding removal of sheet 7 after drizzle)

Next, the building units 2 of the upper floor H are placed on top of the building units 2 of the lower floor L in order from the end (Fig. 4A). At that time, the building unit 2 on the upper floor H is temporarily held above the building unit 2 on the lower floor L, and the building unit 2 on the upper floor H is used to lift the building unit 2 on the lower floor L. cover the top.

Then, the temporary rain end sheet 7 located under the raised building unit 2 of the upper floor H is turned over, temporarily placed on the adjacent temporary rain end sheet 7 and removed, and the upper floor H is placed on the turned up part. The building unit 2 is installed (Fig. 23D(a)). After that, the peeled-up sheet 7 for finishing with a drizzle is separated from the adjacent sheets 7 for finishing with a drizzle, folded, collected and reused. The adjacent temporary rain sheet 7 is left on the building unit 2 of the lower floor L in almost the same state, and the side upper cover part 7a is folded in half to the opposite side and installed. 23D (a). The side upper cover portion 7a is fixed to a scaffold or the like using a binding member such as a band, if necessary. Thereby, the gap between the building unit 2 on the upper floor H and the side upper cover portion 7a of the adjacent temporary rain finishing sheet 7 is eliminated to prevent rainwater from entering.

Thereafter, the above is repeated until all the building units 2 of the upper floor H are installed on the building units 2 of the lower floor L. As a result, all the temporary rain stopping sheets 7 are efficiently removed, and the building unit 2 of the upper floor H is installed on the building unit 2 of the lower floor L while preventing rainwater from entering.

<Effects> According to this embodiment, the following effects can be obtained.

The effect of the base cover 8 will be described below.

(Effect A1) In the base cover 8, the cover member 11 may be divided into cover pieces 12 having portions of substantially the same size and shape as the building unit 2 and provided. A plurality of the cover pieces 12 are arranged and installed on the foundation 3 according to the arrangement and orientation of the building unit 2.例文帳に追加Then, when the building unit 2 is installed on the foundation 3 by using a crane, only the cover piece 12 installed at the part of the foundation 3 where the building unit 2 is installed is turned over to expose the foundation 3 at that part.

This work is carried out while the building unit 2 is floated above the portion of the foundation 3 to be installed, and the portion is protected from rainwater. Further, other portions of the foundation 3 (portions not installed) are left covered with the other cover pieces 12 .

Then, the cover piece 12 is turned over and the building unit 2 is installed on the part where the foundation 3 is exposed. The cover piece 12 that has been turned over is removed, folded and collected. Thereafter, similarly, the building unit 2 is installed while turning over the cover pieces 12 one by one.

By doing so, even when it rains, the building unit 2 can be installed while maintaining a state in which rainwater does not enter the foundation 3 from other locations.

Also, regarding the place where the building unit 2 is installed, when the building unit 2 comes over that place, the cover piece 12 below it is turned over while the building unit 2 is floating above the foundation 3. ing. This makes it difficult for rainwater to enter the foundation 3 from the part where the cover piece 12 is turned up. Therefore, as a whole, the cover piece 12 can be removed while effectively preventing rainwater from entering.

By dividing the cover member 11 into a plurality of cover pieces 12, each cover piece 12 can be handled, which makes handling much easier than when the cover member 11 is formed of a single large-sized member. can be

(Effect A2) In the base cover 8 , the side edge portions of the cover pieces 12 positioned at the boundaries 31 between the building units 2 may be provided with connecting portions 32 and 33 . As a result, the cover pieces 12 are arranged without gaps on the foundation 3 according to the arrangement of the building units 2, and the adjacent cover pieces 12 are easily connected by the connection parts 32, 33 to be integrated. can do. On the contrary, the cover piece 12 can be easily separated (from the integrated state) by removing the connecting portions 32 and 33 . By connecting the cover pieces 12 with the connecting portions 32 and 33, the cover pieces 12 can more effectively suppress and prevent rainwater from entering from between them.

At this time, for example, the connecting portions 32 and 33 are used as fastener portions, and a lead string is tied to the slider 32b of the fastener portion and led to the side opposite to the slider 32b. As a result, by engaging the fastener part on one side of the cover piece 12 and pulling the lead string 32c from the other side, the fastener part can be easily joined (coupling of the cover piece 12) without entering the foundation 3. can be done. Further, after connecting, by guiding the lead string to the opposite side (one side) of the cover piece 12 to the slider 32b, the lead string 32c can be pulled from one side without entering the foundation 3. , the fastener portion can be easily removed (the cover piece 12 can be separated).

In addition, for example, by using hook-and-loop fasteners for the connecting portions 32 and 33, the hook-and-loop fasteners can be easily joined without entering the foundation 3 simply by overlapping and pressing the side edges of the cover pieces 12.例文帳に追加Conversely, it is easy to remove the hook-and-loop fastener.

(Effect A3) In the base cover 8, the cover member 11 may have magnets 41 on the side edges. After the building unit 2 is installed on the foundation 3, the magnets 41 provided on the side edges of the cover member 11 attract and fix the side edges of the cover member 11 to the lower part of the building unit 2 immediately after installation. to The magnets 41 are those of the side edges of the cover pieces 12 adjacent to the installed building unit 2 among the cover members 11 left on the foundation 3 and adjacent to the building unit 2 . As a result, the gap between the installed building unit 2 and the cover member 11 can be quickly closed immediately after the building unit 2 is installed, and rainwater can be prevented from entering through the gap.

(Effect A4) In the base cover 8, the cover member 11 may be supported with respect to the base 3 by the rod-shaped member 51 in an inclined state in which one end side is higher than the other end side. As a result, rainwater can be naturally drained to the outside of the foundation 3 from above the inclined cover member 11 . Therefore, it is possible to prevent rainwater from accumulating on the cover member 11 .

For example, the cover member 11 is supported in an inclined state simply by placing it on the upper side of the rod-like member 51 (horizontal horizontal member 83) installed above one side (for example, the long side 3a) of the foundation 3. can do.

By providing the rod-shaped member 52 in the cover member 11 , the cover member 11 and the rod-shaped member 51 can be integrated simply by passing the rod-shaped member 51 (the vertical oblique member 84 and the upper pressing rod 85 ) through the rod-shaped member 52 . be. The bar member 51 holds the cover member 11 in a straight state. Therefore, the bar member 51 can stably hold the cover member 11 in the inclined state.

By passing the rod-shaped member 51 (vertical diagonal member 84) through the rod-shaped member 52 of the cover member 11 and integrating it, the wind force acting on the cover member 11 is transmitted to the rod-shaped member 51, and furthermore, the rod-shaped member 51 , can be transmitted to the foundation 3 via the fixing bracket 91 and the anchor bolt.

(Effect A5) In the base cover 8, the cover member 11 may be installed so that the height h2 of one end side from the base 3 is higher than the carry-in height h3 of the underfloor equipment 61. FIG. As a result, even after the cover member 11 is installed on the foundation 3, the underfloor equipment 61 can be carried into the foundation 3 at any time before the building unit 2 is installed.

In addition, by utilizing the space under the one end side of the cover member 11 that is lifted up high, even if the cover member 11 is present, the heat insulating material 9 (heat insulating material for foundation) can be applied to the inside of the foundation 3. It is also possible to perform pre-piping.

(Effect A6) In the above, when building units 2 are sequentially installed on the foundation 3, the cover member 11 floats the building unit 2 to be installed above the foundation 3, and the building unit floats. The cover piece 12 located under 2 is removed. By removing the cover member 11 from under the floating building unit 2 in this way, it is possible to prevent the lower part of the foundation 3 from getting wet with rainwater.

(Effect A7) After the building unit 2 is installed in the part from which the cover piece 12 has been removed, the side edge is pulled by the magnet 41 provided on the side edge of another cover piece 12 adjacent to the removed cover piece 12. It is magnetically attracted to the installed building unit 2 . As a result, the space between the building unit 2 and the side edge of the separate cover piece 12 can be quickly closed to prevent rainwater from entering.

(Effect A8) Overlapping portions 18 and 19 are provided on the side edges of the cover piece 12, and the cover piece 12 is placed on the foundation 3 while overlapping the side edges (overlapping over the overlapping portion 19). While overlapping the parts 18), the building units 2 are installed in order from the late side to the early side in the installation order, and the cover pieces 12 are removed in order from the early side to the late side in the installation order of the building unit 2.例文帳に追加Thereby, the cover piece 12 can be efficiently installed and removed from the foundation 3 .

(Effect A9) When the building unit 2 is installed on the foundation 3, the upper surface of the building unit 2 is covered with the temporary rain cover sheet 7, and another building unit 2 is installed next to the building unit 2. , the temporary rain finishing sheets 7 on the upper surfaces of the building units 2 adjacent to each other are connected. As a result, it is possible to protect the upper surface of the building unit 2 from rain by using the rain protection sheet 7.例文帳に追加By connecting the temporary rain sheets 7 together, it is possible to integrate the temporary rain sheets 7 and prevent rainwater from entering from between the temporary rain sheets 7.例文帳に追加

(Effect A10) When the building unit 2 of the upper floor H is installed on the building unit 2, the temporary rain cover sheet 7 covering the upper surface of the building unit 2 prevents the building unit 2 of the upper floor H from being attached to the building unit 2. A temporary rain finishing sheet 7 positioned under the floating building unit 2 on the upper floor H is removed in a state of being floated upward. By removing the temporary rain sheet 7 from under the floating building unit 2 on the upper floor H in this way, it is possible to prevent the upper surface of the lower building unit 2 from getting wet with rainwater.

(Effect A11) The side upper cover portion 7a that covers the upper side of the building unit 2 is formed on the rain shower sheet 7. As shown in FIG. Then, the adjacent drizzle sheets 7 connect the upper side cover portions 7a with the upper side cover portions 7a bent upward, and the connected upper side cover portions 7a are doubled in the connected state. Bend it once. In this way, by folding the upper side cover portion 7a that is bent upward and connected in two, the end portion of the upper side cover portion 7a is hidden inside. Infiltration of rainwater from between the closing sheets 7 can be prevented.

(Effect A12) As a method for removing the base cover 8, the parts of the string members 21, the pegs 24, the fixing metal fittings 91, and the lateral horizontal members 83 on the periphery of the base cover 8 are removed first. The periphery of the base cover 8 is now released and ready for removal of the base cover 8 from the base 3 . By performing this preparatory work immediately before installing the first building unit 2 on the foundation 3, the preparatory work and the work of actually removing the foundation cover 8 become a series of work, eliminating waste in the work. , the time from the preparation work to the start of the removal work is shortened, and the setup can be improved. By improving the preparation of the work, the amount of rainwater entering the foundation 3 from between the foundation cover 8 and the building unit 2 can be reduced. In addition, by improving work arrangements, work can proceed smoothly even in bad working environments such as when it rains, so it is possible to reduce the occurrence of mistakes.

The effect of the installation structure of the base cover 8 will be described below.

(Effect B1) In the installation structure of the base cover 8 , the base cover 8 may be held by bolt members 71 protruding from the base 3 via mounting brackets 72 and rod-shaped members 51 . Thus, the bolt members 71 provided on the foundation 3 can be used to firmly hold the foundation cover 8 on the foundation 3 . Therefore, it is possible to reliably prevent the base cover 8 from being scattered by the wind, and improve the wind resistance performance of the base cover 8 installed on the base 3. - 特許庁In addition, by effectively utilizing the bolt members 71 provided on the foundation 3, the installation structure of the foundation cover 8 can be simplified, for example, there is no need to provide a large-scale structure such as providing an installation structure separate from the foundation 3. .

(Effect B2) In the installation structure of the foundation cover 8, the mounting brackets 72 are composed of a water fitting 81 installed on the water side of the foundation 3 and a water fitting 82 installed on the water side of the foundation 3. , may be provided. The water fitting 81 may be higher than the water fitting 82 . The rod-like members 51 are arranged along the water side and are supported substantially horizontally by the water fittings 81, and are arranged perpendicular to the horizontal members 83 to support the water fittings 81 and the water bottom. A vertical diagonal member 84 that is supported downwardly toward the underwater side by metal fittings 82 may be provided.

As a result, the horizontal horizontal member 83 can be installed at a high position along the side on the water side by the water fitting 81 . In addition, the vertical diagonal members 84 can be installed vertically with the horizontal members 83 with a downward slope by the water fittings 81 and the water fittings 82 .

A base cover 8 is installed on the base 3 so as to cover the base 3. - 特許庁As a result, the water side of the base cover 8 is raised by the water side ends of the water side fittings 81, the horizontal horizontal members 83 and the vertical diagonal members 84, and the water side ends of the water side metal fittings 82 and the vertical diagonal members 84 make it The underwater side becomes lower. The vertical diagonal member 84 allows the base cover 8 to be stretched from the water side toward the water side so that the shape is maintained in a downward slope.

Further, the installation structure of the base cover 8 may be provided with an upper pressing bar 85 arranged between the vertical diagonal members 84 in parallel with the vertical diagonal members 84 and placed on the base cover 8 from above.

Then, the upper pressing bar 85 is placed on the base cover 8 between the vertical diagonal members 84 . As a result, the portion of the base cover 8 on which the upper pressing bar 85 is placed is dented by the weight to strengthen the tension of the base cover 8 and to form a drainage groove 89 on the base cover 8.例文帳に追加The edge of the base cover 8 on the underside of the water is formed into a ridge-and-valley shape by the upper pressing rod 85 and the vertical diagonal member 84, with the vertical diagonal member 84 positioned higher and the upper pressing rod 85 positioned lower. A groove 89 is clearly formed.

(Effect B3) In the installation structure of the base cover 8, the rod member 51 may be adjustable in length. This makes it easier to handle the rod-shaped member 51, and makes it possible to easily handle the rod-shaped member 51 regardless of the condition of the site.

(Effect of screw type joint 51b)

Specifically, at least one of the rod-like members 51 may be capable of connecting and separating a plurality of pipe pieces 51a via a threaded joint 51b. As a result, the horizontal horizontal member 83, the vertical diagonal member 84, and the bar members 51 such as the upper pressing bar 85 can be adjusted in length by the length of the pipe piece 51a. By adopting a structure in which the pipe pieces 51a are connected and separated by the threaded joints 51b, the rod-shaped member 51 can ensure high wind resistance performance.

Among the horizontal horizontal member 83, the vertical diagonal member 84, and the upper pressing bar 85, the bar member 51 that can be connected and separated by the screw joint 51b is composed of a plurality of pipe pieces 51a. Therefore, by separating the pipe piece 51a, the rod-shaped member 51 can be easily handled during transportation, installation, removal, and the like, and can be easily handled regardless of site conditions.

That is, the horizontal horizontal member 83, the vertical diagonal member 84, and the upper pressing bar 85 can be adjusted in length by connecting the pipe pieces 51a with the threaded joints 51b. Therefore, the rod-shaped member 51 can be adapted to foundations 3 of various sizes.

When the building unit 2 is installed on the foundation 3, the horizontal horizontal member 83, the vertical diagonal member 84, and the upper pressing bar 85 are shortened while removing the pipe piece 51a at the screw joint 51b for each building unit 2. It is easy to operate and convenient because it can be removed.

(Effect B4) In the installation structure of the base cover 8 , the rod-like member 51 may be installed by passing through the rod-passing portion 52 provided in the base cover 8 . Accordingly, by passing the rod-shaped member 51 through the rod-passing portion 52, the base cover 8 is stretched and its shape is retained.

By passing the rod-shaped member 51 through the rod-passing portion 52, the base cover 8 and the rod-shaped member 51 are integrated. Therefore, the wind force applied to the base cover 8 can be reliably transmitted to the rod-shaped member 51 via the rod-passing portion 52 .

Further, by fixing the rod member 51 to the foundation 3 via the mounting bracket 72 and the bolt member 71, the foundation cover 8 can be indirectly attached to the foundation 3. As shown in FIG. Therefore, the force transmitted to the rod-shaped member 51 is transmitted to the foundation 3 via the mounting bracket 72 and the bolt member 71 .

(Effect B5) In the installation structure of the base cover 8, the rod through portion 52 includes a lower surface side through portion 52a provided on the lower surface side of the base cover 8, an upper surface side through portion 52b provided on the upper surface side of the base cover 8, may be provided. The vertical diagonal member 84 may be installed on the lower surface side of the base cover 8 through the lower surface side through portion 52a, and the upper pressing bar 85 may be installed on the upper surface side of the base cover 8 through the upper surface side through portion 52b.

By passing the vertical diagonal member 84 through the lower surface side passage portion 52a and the upper pressing bar 85 through the upper surface side passage portion 52b in this way, each rod-like member 51 can be easily and reliably positioned at the correct position with respect to the base cover 8. can be set. The rod-shaped member 51 and the base cover 8 can be reliably assembled on the foundation 3 in a short period of time with less labor simply by passing the rod-shaped member 51 through the predetermined rod-passing portion 52.例文帳に追加

The vertical diagonal members 84 support the basic cover 8 from below, and the upper pressing rods 85 press the basic cover 8 from above.

<Modification>

Modified examples of the base cover 8 will be described below. 24A to 24E show modifications of the base cover 8. FIG.

The base cover 8 of this modification shown in FIG. 24A is used when a plurality of building units 2 all having the same size and shape are installed on the base 3 . 24A(a) shows a case where four building units 2 are installed, and FIG. 24A(b) shows a case where three building units 2 are installed.

In this modification, the base cover 8 has cover pieces 12 that are symmetrical in the width direction. Two types of cover pieces 12 having such a symmetrical structure are prepared: narrow width N cover pieces 12 (FIG. 24B) and wide width W cover pieces 12 (FIG. 24C).

Further, the side surface covering portion 17 is configured entirely or partially (lower portion) separately from the cover piece 12 so that it can be attached to and detached from the cover piece 12 .

Of these, only one cover piece 12 with a narrow width N shown in FIG. 24B is used first. Moreover, the wide width W cover piece 12 shown in FIG. 24C is used for all of the second and subsequent (to the last) pieces.

Since the cover piece 12 with the narrow width N in FIG. 24B is installed at the bottom, the width dimension is narrower than the others. Since the wide width W cover piece 12 in FIG. 24C is placed on top of the cover piece 12, the width dimension is wider than the narrow width N cover piece 12 in FIG. 24B by the amount of the overlapping. The overlapping portions 18 and 19 of both cover pieces 12 are formed to have the same width, and the width dimension is adjusted by the width of the non-overlapping portion at the center of the width.

24E(a) and (b) cover either of the short sides 3c and 3d of the base 3, and have a shape and structure with opposite hand. Therefore, regardless of which of the long sides 3a and 3b of the foundation 3 is on the water side, these two sheets can be used properly.

In order to make the cover piece 12 symmetrical in the width direction, the cover piece 12 has the following configuration.

That is, the cover piece 12 has an upper surface side through portion 52b at the width center position. The overlapping portions 18 and 19 formed on both side edges of the cover piece 12 are made to have the same shape (width and length) and have the same configuration (connecting portions 32 and 33, lower surface side through portion 52a, magnet 41, etc.) are provided in the opposite direction.

In addition, the cover piece 12 is provided with one lower surface side through portion 52a at the position of the width center of the overlapping portion 18 and the overlapping portion 19, respectively. Further, the mounting holes 22 and the auxiliary mounting portions 23 having the mounting holes 22 are arranged symmetrically with respect to each portion such as the peripheral edge portion of the overlapping portion 18 and the overlapping portion 19 .

As described above, the cover piece 12 has a symmetrical structure in the width direction.

At this time, the overlapped portion 18 and the overlapped portion 19 are each provided with a male fastener extending over the entire area along the side edge portion as the connecting portion 32 at the side edge portion. In addition, the overlapping portion 18 and the overlapping portion 19 are provided with female fasteners (parallel to the male fasteners) as separate connecting portions 32 at positions inside the edge portions (boundaries with the non-overlapping portions). to). That is, each of the overlapping portion 18 and the overlapping portion 19 has two types of connecting portions 32 .

A lower surface side through portion 52a is provided in parallel with each of the first connecting portion 32 and the second connecting portion 32 which are installed parallel to each other at equal intervals in the middle portion in the width direction. The length of the lower-surface-side through portion 52a extends substantially to the range of the inner surface covering portion 14 so as not to reach the both end edges of the cover piece 12. As shown in FIG.

One ribbon tape 33a and the other ribbon tape 33b of the hook-and-loop fastener as the connection portion 33 are separated into front side and back side at the same position on the extension line of both ends of the lower surface side through portion 52a. installed individually. One ribbon tape 33a and the other ribbon tape 33b are formed so as to reach both end edges of the cover piece 12 in the portion that will be the side covering portion 16. As shown in FIG. Incisions along the ribbon tapes 33a and 33b are formed on the sides of the connecting portion 33 (hook-and-loop fastener).

Two plate-shaped magnets 41 are attached to the edges of the overlapped portion 18 and overlapped portion 19 of the cover piece 12 near the male fasteners at positions corresponding to both ends of the inner surface covering portion 14, respectively. ing.

As described above, the overlapped portion 18 and the overlapped portion 19 have a symmetrical structure in the width direction down to the smallest detail.

The side covering portion 17 in FIG. 24E has a trapezoidal shape, and folded portions 17a having the shape of a right-angled isosceles triangle having the same sides as the width of the side covering portion 16 are formed at both ends in the longitudinal direction. have as one.

The folded portion 17a is folded in half along the perpendicular bisector at the center of the bottom side so that the equal sides overlap each other. A first ribbon tape 33a and a second ribbon tape 33b, which constitute the connecting portion 33, are attached along the equilateral surfaces. As a result, the folded portion 17a is folded in two and connects the first ribbon tape 33a and the second ribbon tape 33b, thereby forming a three-dimensional shape that fits the corner portion of the base 3. As shown in FIG.

The length of the side covering portion 17 to the folded portions 17a at both ends is the same as the length of the side edge portion of the cover piece 12, and the upper edge portion is connected so as to extend over the entire length. A ribbon tape 32a that serves as the female side of the portion 32 is provided.

Other configurations are substantially the same as those shown in FIG.

Then, each cover piece 12 and the side covering portion 17 are installed on the foundation 3 in the same manner as in the above embodiment, as shown in FIG. 24A(b).

The cover piece 12 is installed so that the wider side of the side covering portion 16 faces the water side. Also, the side covering portion 17 is installed so that the larger folded portion 17a faces the water side.

At this time, the cover piece 12 that is first installed on the foundation 3 is the narrow width N cover piece 12 shown in FIG. 24B. The upper edge (female fastener) of one side covering portion 17 shown in FIG. .

After that, one or a plurality of cover pieces 12 having a wide width W shown in FIG.

That is, the side edge portion (overlapping portion 19) on the short side 3c side of the base 3 of the narrow width N cover piece 12 in FIG. The side edges (overlapping portion 18) are overlapped. The male fastener of the overlapping portion 18 of the cover piece 12 of the wide width W is connected to the female fastener of the overlapping portion 19 of the cover piece 12 of the narrow width N.

After that, the side edge (overlapping portion 19) on the short side 3c side of the base 3 of the wide width W cover piece 12 in FIG. The side edges (overlapping portion 18) are overlapped. The male fastener of the overlapping portion 18 of the cover piece 12 of the wide width W is connected to the female fastener of the overlapping portion 19 of the cover piece 12 of the narrow width N. Further, this operation is repeated as many times as necessary to cover the entire foundation 3 .

Then, when the last cover piece 12 with the wide width W shown in FIG. 24C is installed, the side edge (male fastener) of the last cover piece 12 with the wide width W on the short side 3c side of the base 3 is attached with the fastener shown in FIG. 24E. The upper edge portion (the female fastener of) of the other side surface covering portion 17 is connected. Other installation methods are the same as those of the above embodiment.

As described above, the base cover 8 is installed on the base 3 without any trouble.

According to the base cover 8 of this modified example, the cover piece 12 and the side surface covering portion 17 have a symmetrical structure, so that regardless of whether the long side 3a or 3b of the base 3 is on the water side, the above four types of members The versatility of the cover piece 12 is enhanced. Other than that, it can have the same configuration as the above embodiment, and can obtain the same action and effect.

FIG. 25 is for explaining this embodiment. The parts different from the above embodiment will be described below. Other than that, it is almost the same as the above embodiment, so the description of the above embodiment can be used as the description of this embodiment.

<Construction> The construction of this embodiment will be described below.
In this embodiment, the cover member 11 has a concave portion 101 in the base 3 that slopes down from one end side to the other end side.
The recess 101 may have at its lowest part a drainage nozzle 103 which is inserted into a foundation-penetrating sleeve 102 provided in the foundation 3 .

Here, the concave portion 101 is a depression formed so as to be lower than the upper portion of the foundation 3 by pressing a portion of the cover member 11 that is inside the foundation 3 from above to dent it downward. When the cover member 11 is divided into a plurality of cover pieces 12 , the recess 101 is formed in each cover piece 12 .

Any object may be used to dent the cover member 11, but for example, a rod-like member 51 such as an upper pressing rod 85 (not shown in FIG. 24) is placed from above in the same manner as in the above embodiment. Thus, the weight of the upper presser bar 85 may be used to dent it. The upper pressing bar 85 is so short that the other end does not reach the top of the side (long side 3b) of the foundation 3 on the water side.

One end is positioned above the water side (long side 3a) of the foundation 3, and the other end is positioned in front of the water side (long side 3b) of the foundation 3 and inside the foundation 3. An upper pressing bar 85 is installed so as to be positioned above the bottom surface. In this case, the upper pressing bar 85 may be linear, or may be curved to match the ideal shape of the recess 101 .

As a result, the cover member 11 covers the underside of the foundation 3 (the long side 3b) with the other edge and the side covering portion 16, and the inner portion of the foundation 3 is covered from one end side. It is recessed downward toward the other end (to be lower than the top of the foundation 3). The concave portion 101 has the same drainage function as the drainage groove 89 of the above embodiment.

The base penetrating sleeve 102 is a tubular member that is embedded in the other end of the base 3 and communicates between the inside and outside of the base 3 . In this embodiment, the foundation penetrating sleeve 102 is positioned approximately horizontally or slightly downward toward the outside in the middle or lower position in the vertical direction 4 on the underwater side (long side 3b) of the foundation 3. It is buried so as to form a slope. In this embodiment, the base penetrating sleeve 102 is embedded at the lowermost position of the outer peripheral raised portion of the base 3 .

Note that the foundation penetration sleeve 102 may be used to pass, for example, piping such as water supply pipes and drain pipes, and wiring such as electric wires and signal cables after the rain is over. In this way, wiring and piping are carried out through the foundation penetrating sleeve 102 embedded in the foundation 3, so that maintenance of the wiring and piping arranged through the foundation 3 can be performed without destroying the foundation 3. . The base penetrating sleeve 102 is closed when wiring and piping are not performed.

The fact that the drain nozzle 103 at the bottom of the recess 101 is inserted into the base penetrating sleeve 102 means that the recess 101 slopes downward toward the base penetrating sleeve 102 . In addition, the recess 101 is recessed in such a shape that the end point (lowest part) of the downward slope matches the base penetrating sleeve 102 . Then, the drain nozzle 103 provided at the bottom of the recess 101 enters the base penetrating sleeve 102 .

The drain nozzle 103 is a drain port forming member attached to a through-hole penetrating between the front and back of the cover member 11 . The drain nozzle 103 is attached to the cover member 11 in advance or can be attached on site. The drainage nozzle 103 may be inserted at least into the base penetrating sleeve 102 , but preferably has a length that protrudes outside the base penetrating sleeve 102 . The drain nozzle 103 may have a clogging prevention strainer at the inlet.

As for the water side of the cover member 11, a horizontal horizontal member 83 and a vertical diagonal member 84 are attached to the water metal fittings 81 in the same manner as in the above embodiment so that the water side portion is lifted higher than the upper surface of the foundation 3. You can do it.

Moreover, since the water side of the cover member 11 only needs to be higher than the base penetrating sleeve 102 , for example, the horizontal horizontal member 83 may not be provided, and the height may be approximately the same as the top of the base 3 . In this case, instead of the vertical diagonal member 84, a vertical member 104 or the like may be provided. The vertical member 104 is a rod-shaped member 51 extending substantially horizontally or gently downward from the water side to the water side at a height substantially equal to or slightly higher than the upper portion of the foundation 3 .

The vertical members 104 may be attached to the bolt members 71 provided on the long sides 3a and 3b on the water side and the water side of the foundation 3 using low mounting metal fittings 72 similar to the underwater metal fittings 82. good.
