Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention can be implemented by using a woody material such as a small diameter tree such as a thinned wood or a sawmill generated at the time of sawing, and a minimum unit for constructing a construction surface. Surface unit, semi-surface unit, corner surface unit to be used, the surface structure of a building constructed by selectively using these surface units, and the surface for forming this surface It is about construction methods.

[0002]

2. Description of the Related Art There are many materials and construction methods for constructing building surfaces (wall surfaces with structural strength, for example, walls, floors, and roofs). As a concrete block structure formed by stacking a plurality of concrete blocks formed in a predetermined size in the left and right direction and up and down direction, a log house configured by arranging and stacking logs in a horizontal direction, and a square bar made of laminated wood logs Glued log house, etc.

The technique disclosed in Japanese Patent Application Laid-Open No. H4-155040 relates to a wooden block for forming a wall. A plurality of wooden boards are formed in a rectangular shape, and one side in the longitudinal direction and Forming a tenon on one side surface in the width direction and forming a groove for fitting the tenon on the opposing side surface,
A hole for a bolt penetrated in a vertical direction is formed. In this technique, the blocks can be formed by adjoining the blocks vertically and horizontally and by bolting the blocks in the vertical direction.

[0004]

However, each of the above construction methods has its own problems. That is, in the above concrete block construction, since the material is heavy, the size of the block is reduced from the viewpoint of handling, and there is a problem that the number of repetitions of the work is increased when constructing the construction surface. In addition, since the material is brittle and it is not possible to create a mechanical connection shape, it is connected by joint mortar, but because the block itself and the joint mortar are weak in tension, it is arranged in the hollow part formed inside the block Together with concrete, it is necessary to integrate concrete, it is necessary to provide temporary support except for vertical construction, and construction is difficult. There is a problem of necessity and a problem of poor humidity control. In particular, since the wet work is used, there are problems that the quality is difficult to stabilize, a skilled skill is required, and the site is contaminated.

[0005] In the above-mentioned log house, since the logs are arranged in the horizontal direction, the direction of the wood fibers is orthogonal to the direction in which the gravitational load is applied, which is disadvantageous in terms of structure. In addition, logs are difficult to dry in advance, so there is a problem that they shrink over time after installation and cause long-term maintenance for watertightness and airtightness, and the minimum unit is large and heavy. In addition, there is a problem that a heavy machine is required, and the number of varieties is increased in order to further manufacture parts, and that there is a problem that it is difficult to obtain a log itself due to depletion of wood resources.

[0006] The laminated wood log house has an advantage that the deviation is less than that of a log house using logs.
However, since wood fibers are used in the horizontal direction, there is a similar problem of structural disadvantage. Because the smallest unit is large and heavy, heavy machinery is required for construction and the number of varieties increases in order to produce more parts.The larger the size of glued wood, the higher the workability, the larger the manufacturing equipment, and the larger the variety. If there are too many, there is a problem that production automation is difficult and costs increase.

According to the technique disclosed in Japanese Patent Application Laid-Open No. H4-155040, wood is roughly 600 mm long, 100 mm wide and 20 mm thick.
Are formed in a rectangular shape, and this rectangular plate material is adhered and assembled in the thickness direction to form a block. For this reason, the wood fiber is used in the horizontal direction, and there is a problem that the structure is disadvantageous. Further, since the individual blocks are fixed to each other by using bolts, not only does the material cost increase, but also the workability deteriorates and the construction period is increased.

[0008] An object of the present invention is to provide a plurality of types of trees that can be constructed by using small-diameter trees such as thinned wood and that can be combined with each other to form a floor, a roof, or a wall. It is an object of the present invention to provide a construction unit, a construction structure configured using the construction unit, and a construction method for configuring a construction surface using the construction unit.

[0009]

In order to solve the above-mentioned problems, a typical construction unit according to the present invention includes a plurality of core square members having a rectangular cross section of the same size and two square plates of the same size. A face unit, wherein the core squares are arranged in one or more rows in parallel, each row having a plurality of core squares arranged in parallel at substantially equal intervals, and the core squares adjacent in a row direction. The interval between the core bars is made slightly larger than the width of the core bars in the row direction.
Two square plate members are arranged, each core square member protrudes to at least one side of the two square plate members, and the total protruding length of each core square member is equal to or less than the length of the square plate member in the length direction of the core square member. In the case where the core squares are arranged in parallel in a plurality of rows, the spacer material is disposed so as to be sandwiched between the rows of the core squares, and the spacer material does not protrude from the two square plate materials. It is composed.

In the above construction unit, a plurality of core square members having a rectangular cross section are disposed between two square plate members at an interval slightly larger than the width of the core square members, so that the square plate members and the core members are arranged at a distance from each other. A square insertion space having a size slightly larger than the core square member is formed between the square member and the square plate member, and a space which is half of the square insertion space and is open on one side at both ends of the rectangular plate member. Is formed. Further, the core square member protrudes from at least one side of the rectangular plate member with a length equal to or less than the length of the rectangular plate member in the same direction.

Therefore, the protruding directions of the core bar members are arranged in the same direction, and a large number of structural units are laterally displaced from each other, and the core bar members protruding from one of the structural units are formed in the square shape of the other unit. By being fitted into the insertion space, they can be connected to each other. When the core bar is inserted into the square insertion space in this manner, there is no gap between the core bar and the square plate, and there is no gap between the core bar fixed to the square plate and the fitted core bar in advance. The set slight gap is formed. That is, the surface units are connected to each other in a dense state. Therefore, high resistance can be exerted even when an out-of-plane force acts on the construction surface.

In the above construction unit, it is preferable that the rectangular board is a wood board and includes a portion having a wood fiber direction parallel to the length direction of the core square wood. In this way, by arranging a part or all of the wood fiber direction of the square plate parallel to the length direction of the core square bar, it is possible to rationally bear the gravitational load acting on the construction unit, In addition, it is less likely to contract with the action of a gravitational load.

[0013] It is preferable that the rectangular plate has a step portion for returning water along edges of both sides in a direction perpendicular to the length direction of the core rectangular member. It is preferable to have a drain groove for drain along the edges of both sides in a direction parallel to the vertical direction.

[0014] It is preferable that a wedge driving groove is formed in at least an end portion of the arranged core square members which is located at an end portion and at least on a head portion protruding from the rectangular plate member. In the case where a groove for driving a wedge into the head of the core square bar is formed in this manner, the face units are arranged adjacent to each other, and the core square bar of one frame unit is formed in the square space of the other frame unit. Then, by inserting a wedge into the groove, the head of the core square member can be spread and pressed against the inner surface of the rectangular plate member.
For this reason, the joint strength between the combined surface units can be improved.

In the case where each row is constituted by an odd number of core square members, a large number of surface units can be combined by arranging break joints.

Further, the semi-planar unit has a shape obtained by bisecting the above-described planar unit with a plane perpendicular to the plane of the rectangular plate and parallel to the length direction of the core square. In this semi-planar unit, it is possible to adjust the dimension of the end of the structural surface formed by combining the above-described structural units.

[0017] The corner surface unit is formed of two ends of two square plate members parallel to the length direction of the core square member from the outer surface of the core square member disposed at the end of each of the above-described surface units. The distance to the edge is set to a preset value, the edges of the two rectangular plates are connected by a connecting plate, and a core bar located at the end and a core bar in a range from the connecting plate are present. In such a case, a communication space that communicates vertically is formed in the above range without projecting the core square bar.

In the corner unit, the corner unit is sandwiched between rows of core members when the core members are arranged in a plurality of rows in parallel. It is preferable that the end of the spacer material is in contact with the connecting plate connecting the edges of the two rectangular plates across the hole.

In each of the above-described corner surface units, one edge parallel to the length direction of the core square bar of the rectangular plate is connected by the plate, so that many surface units and semi-surface units are vertically connected. Then, a vertical surface is constructed, and the corner surface unit is placed at the intersection of this surface and stacked up to form the intersection of the surface without exposing the core timber and square space. You can do it.

A typical surface structure according to the present invention is such that the above-described surface units are closely arranged in a plane, and the projecting portion of the core beam is interposed between the core beams of other surface units adjacent in the protruding direction. It has a portion which is fitted and arranged at a break joint.

In the above construction, when a plurality of construction units are arranged in close contact with each other in a plane to form a break joint construction surface, a core square bar projecting from one of the adjacent construction units is attached to the other. It can be fitted in the insertion space between the core square members formed in the construction unit. In particular, since the sum of the protruding lengths of the core square members is equal to or less than the length of the rectangular plate member constituting the structural unit in the core square direction, the configured structural surface includes the core square member of one structural unit and the other structural surface. The rectangular plate members of the unit overlap in the thickness direction, and have apparently continuous members.

For this reason, when an out-of-plane force acts on the constructed structure, it is possible to distribute the force to all the structures and to bear the force on each of the structure units, thereby improving the strength reliability. Can be obtained.

It is preferable that every other half-surface unit is arranged so that at least one lateral edge of the surface structure arranged at the break joint is straight.

[0024] A corner surface unit is used at a portion where the surface structures in the orthogonal direction stacked in the break joint intersect, and the corner surface units are stacked in different directions. preferable. In particular, a tenon having the same cross-sectional shape as the core square bar and a length equal to or less than the vertical dimension of the rectangular plate is inserted into a communication space formed at a crossing portion of the vertically adjacent corner unit. Therefore, it is preferable that upper and lower corner surface units are connected to each other.

In a typical construction method according to the present invention, a plurality of the construction units are used, and each construction unit is formed in a planar shape, and the projecting portion of the core bar is formed in another structure adjacent to the projecting direction. The method is characterized in that it has a step of inserting between core square members in the surface unit, sequentially connecting them, and arranging a break joint.

In the process of arranging the framing units at the break joints, it is preferable to arrange every other semi-framing unit so that at least one lateral edge of the framing structure is straight.

A large number of surface units are closely arranged vertically and horizontally with the longitudinal direction of the core square bar as the vertical direction, and the protruding portions of the core square bars are fitted between the core square bars of the structural unit arranged above to break joints. It is preferable to use a corner surface unit at a portion where the plurality of stacked surface structures intersect, arrange the corner surface units in the up-down direction, and stack the units in different directions.

A tenon having the same cross-sectional shape as the core square bar and a length equal to or less than the vertical dimension of the square plate is inserted into the communicating space formed at the crossing part of the vertically adjacent corner unit. It is preferable that upper and lower adjacent corner surface units be connected by stacking while being fitted.

First, the configuration of a standard construction unit A (hereinafter referred to as a "planar unit A") constituting a construction surface such as a wall surface, a floor surface or a roof surface will be described with reference to FIGS. The flat unit A includes two square plate members 1 arranged in the thickness direction, core square members 2 and 3 arranged in two rows between the two square plate members 1 and constituting each row, and two square plate members. It is configured to include two spacer square members 4 serving as spacer members arranged at a predetermined interval between the arranged core square members 2 and 3.

The rectangular plate 1 is formed with a predetermined dimension. That is, in the square plate 1, FIG.
The length in the length direction (hereinafter, referred to as “vertical direction or height direction”) of the core square bars 2 and 3 in (b) is the same as that of the water return 1 described later.
The dimension in the direction perpendicular to the length direction of the core square members 2 and 3 (hereinafter referred to as “lateral direction or width direction”) in FIG. Are set in accordance with the dimensions of the side of the fore edge and the number of lines constituting the row,
The thickness is set according to the size of the side of the fore-edge of the core square members 2 and 3.

In the present embodiment, the fore ends of the core square members 2 and 3 are set to have a square cross section with a side length of about 40 mm.
The number of core square bars 2 and 3 constituting the row is set to five, which is an odd number. And the length in the width direction of the square plate 1 is about
The thickness is set at 400 mm and the thickness is about 40 mm. But,
The dimensions of the rectangular plate 1 are set as standard dimensions in the present embodiment, and it is a matter of course that the dimensions are not necessarily limited to these dimensions.

The rectangular plate 1 may be formed of a single plate, or may be formed by integrating a large number of wooden materials. However, in any case, since the gravitational load acts on the square plate 1, it is necessary to arrange the wood fiber direction in the height direction so as to be able to bear these loads rationally. . In particular, when the square plate 1 is formed of a single plate, the wood fibers of the plate 1 are all arranged in the height direction.

In this embodiment, in order to effectively use small-diameter trees such as thinned lumber and scrap wood, a large number of wood materials are arranged by arranging the wood fibers in the height direction, and are bonded to each other in this state. Glued laminated lumber is used. By using the rectangular board 1 made of such a laminated wood, it is possible to manufacture the square board 1 without waste using materials such as wood pieces and offcuts collected from thinned thinned wood.

In particular, pieces of wood having a finishing allowance and dried sufficiently are arranged in the direction of the wood fiber, and a finger joint or a scarf joint is formed and connected in the direction crossing the wood fiber to form a long piece. It is possible to form a large plate of laminated wood having a desired area by forming square bars and arranging the square bars in a direction parallel to the direction of the wood fibers and bonding them together. The square plate 1 can be formed by cutting the large plate to a desired size and forming a water return 1a or the like to be described later. The thus-produced square plate 1 is sufficiently dried, and can reduce temporal deformation (curling).

The rectangular plate 1 formed as described above has an upper side surface in the height direction, and a stepped portion for the water return 1a is formed along one edge and the lower side surface. A concave portion 1b for receiving the water return 1a is formed at an edge corresponding to a portion where the water return 1a is formed. The water return 1a has a function of preventing rainwater or the like splashing on the outdoor side from penetrating into the structural unit.

Drainage drains 1c are formed on both sides of the rectangular plate 1 in the width direction. This drain 1
c exhibits a function of blocking a capillary phenomenon that occurs at joints formed when a plurality of flat units A or semi-surface units or corner surface units described below are connected in the width direction. Even if rainwater permeating the outdoor side penetrates into the structural unit from the joint portion due to the capillary phenomenon, when it reaches the drain groove 1c, it can flow down along the groove 1c. .

The rectangular plate 1 has an inner surface 1d on the edge side where the water return 1a and the concave portion 1b are formed, and a surface 1e on the opposite side. In addition, the size of the surface 1e in the height direction is set to about 200 mm by setting the dimensions of the water return 1a and the recess 1b to 10 mm, respectively.

Each of the core square members 2 and 3 is made of a wood material having the same size and a rectangular cross section, and is formed by arranging the wood fibers in the length direction. The core squares 2 and 3 are formed by connecting materials such as thinned wood and small-diameter trees and scraps in the wood fiber direction through finger joints and the like to form long squares. It is manufactured by cutting it.

Each of the core square members 2 and 3 is formed in a square cross section having a side of about 40 mm, which is substantially equal to the thickness of the rectangular plate member 1, and has a length in the height direction (200 mm excluding the water return 1a).
mm) is set slightly smaller than or less than twice. Further, chamfered portions 2a, 3a are formed at the respective edge portions of the upper end portions of the core square members 2, 3 in the length direction.

The core square bar 2 has only a chamfered portion 2a formed simply at the upper end in the longitudinal direction. Further, of the upper and lower end surfaces in the longitudinal direction of the core square bar 3, at least an end surface protruding from the rectangular plate member 1 is formed with a cross-shaped cut having a predetermined depth and an intersection of these cuts. A wedge driving groove 3b formed of a substantially circular groove is formed. Therefore,
By driving the wedge 7 shown in FIG. 9 into the groove 3b, the cut portion of the core square bar 3 can be expanded.

In forming the flat unit A, the core square members 2 and 3 are formed by arranging the core square members 3 having the grooves 3b at the head and tail, in other words, at both ends in the width direction of the flat unit A. A predetermined number of core square bars 2 are arranged between the two.

The spacer bar 4 is made of the same material as the core bars 2 and 3. That is, it is formed by cutting a timber formed by connecting wood materials in the wood fiber direction to a desired length. This spacer bar 4 has a side of about
It has a square cross section of 40 mm, and its length is set to about 400 mm, which is substantially equal to the length of the rectangular plate 1 in the width direction.

As described above, the thickness of the square plate 1 and the dimensions of the edges of the core squares 2 and 3 and the spacer square 4 are all substantially the same.

Next, a specific description will be given of the configuration of the flat unit A composed of the members 1 to 4 described above. In this embodiment, two rows of core squares 2 and 3 are arranged between two square plates, and a spacer square 4 is arranged between the two rows of core squares 2 and 3.

The core square members 2 and 3 are arranged such that the length direction is parallel to the height direction of the rectangular plate member 1 and the core square members 3 are arranged at both ends in the width direction of each row. To 3
The core square members 2 are arranged. In addition, the core square members 2 and 3 in each row are arranged with an interval of a dimension slightly larger than the length of the edge side of the core square members 2 and 3 (about 41 mm to 42 mm in this embodiment). In addition, the distance between the outer side surface of the core bar 3 and the side surface in the width direction of the rectangular plate 1 is set to have a dimension which is about の of the length of the side of the edge of the core bar 2 or 3. Further, the core square members 2 and 3 are arranged in such a manner that their ends in the length direction project from one side of the rectangular plate 1 with a length equal to or less than the height dimension of the rectangular plate 1.

The two rows of core square bars 2, arranged as described above,
3, two spacer bars 4 are attached to each core bar 2, 3.
The direction perpendicular to the length direction (width direction of the rectangular plate 1)
And are spaced apart from each other. 2
The distance between the outer surfaces of the two spacers 4 is the square plate 1
Must be less than or equal to the height dimension of

The two square plate members 1 and the core members 2, 3 arranged in two rows, the core members 2, 3 and the spacer members 4
Are contacted with an adhesive to form a flat unit A.

Accordingly, in the flat unit A, between the adjacent core members 2 and 3 in each row and between the core members 2 and
3, a rectangular insertion space 5 defined by the square plate 1 and the spacer bar 4, and two spacer bars 4 between and along the spacer bars 4.
And a sleeve space 6 defined by the core square members 2 and 3. Further, core square members 2 and 3 protrude from one side of the rectangular plate 1 in the height direction.

In the flat unit A constructed as described above, the insertion space 5 has a dimension in the width direction slightly larger than the length of the side of the edge of the core square bar 2, 3 and a dimension in the thickness direction of the core. The lengths of the sides of the timbers 2 and 3 naturally become substantially equal.
In the insertion space 5 formed with the above dimensions, the space 5
The core square members 2 and 3 of another planar unit A adjacent to the core square members 2 and 3 can be inserted by facing the core square members 2 and 3 with a hammer or the like.

In particular, when the rectangular plate 1, the core members 2, 3 and the spacer members 4 constituting the plane unit A expand, the dimension of the insertion space 5 in the thickness direction increases with the expansion of the core members 2, 3. The dimension in the width direction is reduced. For this reason,
The dimension of the insertion space 5 in the width direction is reduced. However, since this direction is formed with a dimension having a margin of 1 mm to 2 mm in advance, it is possible to insert the core square members 2 and 3 constituting another flat unit A under the same condition into the insertion space 5. .

Here, a state where the two plane units A are joined in the length direction of the core square members 2 and 3 will be described with reference to FIG. As shown in the figure, two plane units A are arranged in the longitudinal direction of the core square members 2 and 3, and the other core unit 2 and 3 of one plane unit A (the lower plane unit A in the figure) are connected to the other. Of the flat unit A (the upper flat unit A in the figure) is arranged to face the insertion space 5. Then, by placing a backing plate on the end of the core square members 2 and 3 of the upper flat unit A and hitting it with a hammer or the like, the core square members 2 and 3 of the lower flat unit A are inserted into the insertion space 5 of the upper flat unit A. Is inserted into.

When the lower surface in the height direction of the rectangular plate 1 constituting the upper flat unit A abuts on the upper surface in the height direction of the rectangular plate 1 constituting the lower planar unit A, the two planar units The coupling of A is completed. At this time, the ends of the core square members 2 and 3 of the lower flat unit A coincide with the upper side surfaces of the square plate 1 of the upper flat unit A. In this state, the core square members 2 and 3 of the lower flat unit A are in firm contact with the inner surface 1d of the square plate 1 of the upper flat unit A by friction contact.

In order to strengthen the frictional connection between the lower plane unit A and the upper plane unit A, a wedge 7 is driven into a groove 3b formed at the end of the core bar 3 disposed at both ends of the row. I have to. That is, the rectangular plates 1
After the side surfaces in the height direction abut against each other to complete the connection of the two plane units A, the groove 3b of the core square bar 3 of the lower plane unit A inserted into the insertion space 5 of the upper plane unit A
By driving the wedge 7, the end of the core bar 3 corresponding to the groove 3 b is expanded, whereby the upper flat unit A can be pressed against the flat unit A with a larger force to obtain higher bonding strength. It is.

By repeating the above procedure and sequentially connecting a large number of flat units A, it is possible to form a construction surface such as a wall surface, a floor surface, or a roof surface. Especially,
When a large number of flat units A are combined, when the core square members 2 and 3 of one flat unit A are opposed to the insertion space 5 of the other flat unit A, the width in the width direction of the rectangular plate 1 of the two flat units A is determined. The sides are not arranged in a straight line, but form a zigzag. For this reason, in order to make the zigzag side surfaces straight, a half-surface unit (hereinafter, referred to as “half unit B”) having a half width of the plane unit A is arranged.

Next, the configuration of the half unit B will be described with reference to FIG. In the drawing, the same portions and portions having the same functions as those of the above-described flat unit A are denoted by the same reference numerals, and description thereof is omitted.

The half unit B is the flat unit A described above.
Is cut at the center in the width direction. That is, the half unit B is perpendicular to the surface of the rectangular plate 1 about the core square 2 located at the center of the five core squares 2 and 3 in the plane unit A and has a length equal to the length of the core squares 2 and 3. It is configured to have a shape cut along a plane parallel to the vertical direction, and the configuration in the thickness direction is exactly the same as the flat unit A.

The half unit B arranges the core bar 8 obtained by cutting the core bar 2 in the width direction and the two core bars 3 and arranges the rectangular plate members 1 on both outer sides of the row, respectively. Two spacer square members 4 are arranged between them, and they are integrated by bonding their contact surfaces. Therefore, in the half unit B, the outer surface of the half-cut core bar 8 is flush with the side surface of the square bar 1 in the width direction.

When the plane unit A and the half unit B configured as described above are used to form two orthogonal wall surfaces, the interior of each of the constituent units A and B is exposed at the intersection of these wall surfaces. must not. For this reason, at the intersection, the corner-side surface units C and D (hereinafter referred to as “corner unit C”) whose interiors are shielded by connecting the widthwise edges of the two rectangular plate members 1 by the connection plate member 12. , D ")
Is used.

Next, the configuration of the corner unit C will be described with reference to FIGS. In the corner unit C, the same portions and portions having the same functions as those of the flat unit A described above are denoted by the same reference numerals, and description thereof is omitted.

The corner units C are vertically adjacent to each other at the intersections of two orthogonal wall surfaces formed by connecting a large number of plane units A, and the corner units C overlap each other when they are stacked. A communication space communicating with each other is formed, and a tenon 10 is inserted into this communication space to connect the upper and lower corner units C.

The length of the side of the fore edge of the tenon 10 is equal to that of the core square members 2 and 3, and the length is the square plate member of the corner unit C.
It is configured to have a length that is approximately half of the height dimension of the eleven core bar 3. In addition, both ends of the tenon in the longitudinal direction are
A chamfered portion 10a is formed similarly to the end of the core square bar 3, and a groove 10b for driving the wedge 7 is formed. The depth of the groove 10b is formed to be about half the value of the groove 3b formed in the core square bar 3.

The corner unit C is composed of core square members 2 and 3 having one upper end side arranged so as to protrude in the height direction of the rectangular plate 11.
The distance from the outer surface on the side of the edge 11a of the core bar 3 disposed at the end of the rectangular plate 11 to the edge 11a in the width direction of the rectangular plate 11 is one core bar 3 corresponding to the thickness of the corner unit C. The connecting plate 12 arranged on the basis of the edge 11a connects the ends of the two rectangular plates 11. By connecting the end portions of the rectangular plate members 11 with the connecting plate members 12, the internal configuration of the corner unit C is not exposed to the outside.

As shown in the figure, in the present embodiment, each row of the core square members protruding from the height direction of the rectangular plate member 11 is one. However, the present invention does not necessarily limit the number of projecting core square bars in the corner unit C to one in each row. That is, it is natural that the number of projecting core square bars differs depending on the width dimension of the corner unit C. However, it is essential that at least one core square bar 3 in each row protrudes.

The corner units C are stacked and joined in the height direction while intersecting each other. Therefore, the square plate 11
A part of the water return 1a formed on the upper side surface of the corner unit C may be deleted corresponding to the position and thickness of the square plate material 11 of the corner unit C (thickness of the corner unit C) to be superimposed on the upper side. Alternatively, it is necessary to delete a part of the lower side surface in correspondence with the position and height of the water return 1a.

In the present embodiment, a part of the water return 1a is deleted to form a deleted part 11b, and the lower end of the square plate member 11 of the corner unit C stacked upward on the deleted part 11b is formed. It is configured to be able to fit.

The connecting plate 12 has a thickness substantially equal to that of the rectangular plate 11, and a water return 1a is formed at the edge of the upper surface in the height direction substantially in the same manner as the rectangular plate 11. A concave portion 1b for receiving the water return 1a is formed on the lower side surface.
Therefore, when the edges 11a of the two rectangular plate members 11 are connected by the connecting plate member 12, a water return 1a having a cut-out portion 11b is formed on the upper surfaces of these plate members 11, 12 and continuous on the lower surface. The recess 1b is formed.

A plurality of corner units C intersect with each other on a plane defined by the core bar 3, the two rectangular plates 11, and the connecting plates 12 located at the ends of the protruding rows. Stacked in the direction. The stacked corner units C are connected via a tenon 10 formed as a separate member. Therefore, a communication space 13 that penetrates in the height direction and communicates with each other is formed on the planes that intersect each other in the stacked corner units C.

The communication space 13 may be defined by the inner surfaces of the rectangular plate members 11 of the two corner units C stacked one above the other. In this case, the tenon is configured to have the same cross-sectional shape as the hole. In particular, as will be described later, in the corner unit I in which the core square members 2 and 3 are arranged in one row between two rectangular plate members 1, the communication space
A communication space 13 having the inner dimensions of the rectangular plate 1 is formed at 13.

In this embodiment, as shown in FIG.
When the spacer bar 4 is disposed in the communicating space 13 across the spacer bar 4 and the tip of the spacer bar 4 is brought into contact with the connecting plate 12, and when the two corner units C are stacked crossing each other, the other corner portion is stacked. The unit C is provided with a core square 14 at a position closed by the spacer square 4 and the square plate 11.

That is, in the present embodiment, a plurality of core
14 are arranged at substantially equal intervals, and the core square 14 and the square plate
A communication space 13 substantially equal to the insertion space 5 is formed by the connection plate 11 and the connection plate 12.

The edge of the core bar 14 has the same size as the edge of the core bars 2 and 3. In addition, when they are stacked so as to cross each other, the spacers 4 of the other corner units C that are stacked face each other in the height direction, so that the length is equal to the height of the square plate 11 excluding the water return 1a. Have a value. Therefore, the connecting plate material in the corner unit C
In the range from the 12 side to the outer surface of the core bar 3 on the side of the connecting plate 12, no core bar protrudes.

In the corner unit C configured as described above, the other corner units C are crossed over the corner unit C arranged below, and the connecting plate 12 of each other is the same as the square plate 11 of the other party. When they are arranged and stacked so as to form a plane, the lower surface of the rectangular plate material 11 in the upper corner unit C fits into the deleted portion 11b of the water return 1a formed on the upper surface of the lower corner unit C. I do.

The tenon 10 is inserted into the communication space 13 of the corner units C stacked up and down, and the tenon 10 is arranged so as to penetrate the two corner units C, thereby connecting these corner units C. It is possible. When the two corner units C are connected in this manner, one core unit 3 is provided between the core square bar 3 of the corner unit C arranged below and the square plate 11 of the corner unit C arranged above. A space having a depth substantially equal to the side of the fore edge of the core square bar is formed.

Further, as shown in FIG. 4B, at the intersection of the stacked corner units C, the spacer square member 4 is simply arranged to cross the communicating space 13 without disposing the core square member 14. But it is good. In the case where the spacer bar 4 is disposed in the communication space 13 so as to traverse the spacer bar 4, it is preferable that the tip of the spacer bar 4 is disposed so as to abut the connecting plate 12. As described above, when the spacer bar 4 is traversed in the communication space 13, when the two corner units C are crossed and stacked, the communication space 13 is formed by the crossed two spacer bar 4 of the core bar 2, 3. It is divided into four spaces having a shape substantially equal to the cross-sectional shape. That is, in the plurality of stacked corner units C, the communication space 13 is partitioned by the spacer square members 4 in plan view, and the projected area and the shape of the communication space 13 are substantially equal to the insertion space 5.

FIG. 6 is a view for explaining a corner unit D according to another configuration. In the drawing, the same portions and portions having the same functions as those of the above-described corner unit C are denoted by the same reference numerals, and description thereof is omitted.

As shown in the figure, the corner unit D according to the present embodiment, when the two corner units D are combined, the core unit D of the corner unit D disposed below which is closest to the connecting plate 12 The side surface of the square member 2 is configured to substantially contact the rectangular plate member 11 of the corner unit D arranged above. For this reason, although the plurality of core squares 2 and 3 are arranged at substantially equal intervals, the core squares 2 and 3 are
14 are not arranged at equal intervals.

That is, the core square bar 14 is disposed substantially adjacent to the core square bar 2 closest to the connecting plate 12. And a water return 1a formed on the upper surface of the square plate 11
Is formed at a position substantially corresponding to the core square bar 14.

Even with the corner units D configured as described above, when the corner units D are vertically stacked while intersecting each other, the lower surface of the corner unit D disposed above the lower corner unit D It fits into the removed portion 11b of the water return 1a formed on the upper surface. Further, by inserting the tenon 10 into the communication space 13 of the stacked corner units D, it is possible to firmly connect the two.

The relationship between the lengths in the width direction of the units A to D configured as described above will be described with reference to FIG. As shown in the figure, the length L in the left-right direction of the flat unit A is a standard size, and the other units B to D have dimensions set in advance with respect to the standard size. That is, the length L of the half unit B in the left-right direction is configured to have a dimension of about L / 2 of the plane unit A, and the length L of the corner unit C in the left-right direction is about 3L / 4 of the standard unit A. The length L of the corner unit D in the left-right direction is about 5 L / 4 of that of the plane unit A.
However, it goes without saying that the present invention does not limit the dimensions of the units A to D.

Next, a brief description will be given of a case in which the flat unit A and the half unit B form a structure having no intersection such as a horizontal surface such as a wall surface, a floor surface or a roof surface, or an inclined surface. First, a number of flat units A opposed to the first row of the construction surface to be configured are aligned by closely contacting the ends in the width direction, and at the same time, a half unit B is placed at one end of the row of the flat units A. Keep them aligned. In this state, the units A and B are not connected to each other at all.

Next, each unit A,
The units A and B in the second row are arranged adjacent to each other in the direction of the core members 2 and 3 projecting from B. At this time, the plane units A in the second row are arranged corresponding to the ends of the half units B in the first row, and the plane units A are aligned based on the plane units A. Is shifted by ピ ッ チ pitch of the length in the width direction, that is, the break joint is arranged.

Next, the units A and B in the second column arranged in the units A and B in the first column are connected to the units A and B in the first column (hereinafter, the flat units A are connected to each other). Will be described). The coupling of the plane units A adjacent to the first and second rows is performed by inserting the projecting portions of the core members 2 and 3 of the plane units A in the first row into the insertion spaces 5 of the plane units A in the second row. It is done by letting it.

When the joining operation of the adjacent flat units A is performed, the members defining the dimension in the thickness direction of the insertion space 5 of each flat unit A are the core square members 2 and 3.
In some cases, it is difficult to insert the core square members 2 and 3 into the insertion space 5. However, since the wooden material has appropriate elasticity, the core square members 2 and 3 protruding from the plane unit A in the second row are separated by a wooden hammer or the like. It can be easily inserted by hitting.

In the insertion space 5 of the flat unit A arranged above, the core square members 2 of the flat unit A arranged below are arranged.
3 is inserted, and when the lower surface of the rectangular plate 1 of the planar unit A disposed above and the upper surface of the rectangular plate 1 of the planar unit A disposed below come into contact with each other, the groove 3b of the core rectangular member 3
The inner surface 1 of the square plate 1 of the plane unit A disposed above by expanding the end of the core square bar 3 by driving the wedge 7
d and press it against the adjacent core bar 2 (see FIG. 8).

Therefore, the connected flat units A are not loosened, and the protruding portions of the core square members 2 and 3 are inserted into the insertion space 5. Then, the plane unit A arranged in the first row is combined with the two plane units A arranged in the second row, and all the plane units A and the half units B are firmly coupled by a chain of this combination. Is possible.

By repeating the above operation while arranging the half units B every other row at the end of the row of the plane units A, a predetermined row is formed by connecting the plane units A in a predetermined row. Then, the plane unit A arranged in the last row of the structure is connected to the already connected plane unit A. At this time, the protruding portions of the core square members 2 and 3 from the square plate member 1 of the plane unit A arranged in the last row are cut in advance or at the site to form a structure with no protruding parts arranged at the break joint. It is possible to

Next, a procedure for constructing a construction surface having an intersection such as a wall surface will be described with reference to FIGS. In addition, since the plane part in each structural surface is formed by stacking a plurality of plane units A and connecting the plane units A to each other as described above, the description of the structure of the plane part will be omitted below. I do.

First, a structure having an L-shaped intersection will be described with reference to FIGS. As shown in FIG. 10A, first, the units A and C of the first stage are arranged. In the first stage, the corner unit C is arranged at the intersection,
A surface in two directions is formed based on the corner unit C.

That is, a plurality of flat units A are arranged in close contact with each other in the width direction of the corner unit C, and an adjustment unit E for dimension adjustment is arranged in the thickness direction of the corner unit C. A plurality of flat units A in the width direction of E
Are arranged in close contact. At this time, the tenon 10 is inserted into the communication space 13 substantially equal to the insertion space 5 formed in the corner unit C, and the length thereof is made to protrude by about 1/2. In order to prevent the tenon 10 inserted into the upper half of the communication space 13 from dropping, a tenon having a half length of the tenon 10 is buried in the lower half of the communication space 13 in advance.

The adjusting unit E has the same dimension in the thickness direction as the other units A to D, and the dimension in the width direction indicates the relationship between the thickness of each unit A to D and the width of the plane unit A. Is set by When the relationship between the thickness and the width of the plane unit A is about 1: 2 as in this embodiment, the width of the adjustment unit E is set to about ／ of the width L of the plane unit A. That is, the width of the adjustment unit E is a size obtained by subtracting a dimension of about の of the thickness of the unit A from the width of the flat unit A. Therefore, the width dimension of the adjusting unit E is set according to the ratio of the thickness to the width of the flat unit A and the width dimension of the unit A, and at the same time, the number of core square members 2 and 3 is also set.

As described above, after the corner units C are arranged at the intersections and the units A, C, and E of the first stage are arranged at predetermined positions, as shown in FIG. The units A, C and E of the second stage are arranged and connected to the units A, C and E constituting the first stage.

In the second-stage corner unit C, the connecting plate 12 is arranged so as to be flush with the square plate 11 of the first-stage corner unit C and stacked. At this time, the tenon 10 previously projecting from the first-stage corner unit C is connected to the communication space 13 of the second-stage corner unit C similarly to the core square bar 3.
At about half the depth below After stacking the second-stage corner unit C on the first-stage corner unit C, a new tenon 10 is inserted into the communication space 13 of the second-stage corner unit C. When the new tenon 10 is inserted, the wedge 7 is lightly inserted into the groove 10b on the lower side of the tenon 10, and after the wedge 7 reaches the groove 10b of the tenon 10 already inserted, a new tenon is inserted. Hit 10 and wedge 7 both mortises 10
The upper and lower corner units C are firmly integrated via the tenon 10.

By repeating the above procedure, it is possible to construct a surface having an L-shaped intersection. In the above-described construction, the plane units A stacked in a plurality of stages are mutually 1
/ 2 pitches of break joints are shifted.

The core square members 2, 3 protruding from the flat unit A, the corner unit C, and the adjusting unit E, which are arranged at the uppermost stage of the structure on which the joints are stacked as described above, are previously or on-site. May be resected.

Next, a procedure for forming a surface having a T-shaped intersection will be described with reference to FIGS. Note that the procedure of stacking and combining the units A and C is the same as the above-described configuration of the plane portion and the surface structure having the L-shaped crossing portion. The description of the combining procedure is omitted.

As shown in FIG. 12A, in the first stage,
The plane unit A is arranged adjacent to the corner unit C in the width direction and opposite to the side where the connecting plate 12 is arranged, and the adjustment unit F is arranged adjacent to the connecting plate 12 and the unit F is interposed therebetween. The flat unit A is arranged, and the adjusting unit E is arranged in contact with one of the square plate members 11 of the corner unit C to form a T-shaped intersection.

The adjusting unit F has the same dimension in the thickness direction as the other units A to E, and the dimension in the width direction is か ら of the thickness of the half unit B in the width direction. It is formed to have the deducted dimension, that is, about の of the plane unit A.

In the second stage, the corner unit C is arranged with its position changed by 90 degrees clockwise from the first stage, and the plane unit A is arranged adjacent to the corner unit C. In addition, rectangular plate material on both sides of the corner unit C
The adjusting units E abut against the respective 11, and the flat unit A is arranged adjacent to the adjusting unit E.

After the units A, C, and E arranged in the first and second stages are combined with each other, the units A, C, and E in the second stage are placed above the units in FIG. As shown in FIG. C, E, and F are arranged. Third

The flat unit A is arranged adjacent to the opposite side of the flat plate unit A, the flat unit A is arranged on the connecting plate 12 side via the adjusting unit F, and the adjusting unit E is applied to one square plate 11 of the corner unit C. The T-shaped intersection is formed by contacting and arranging the plane unit A via the unit E.

After the units A, C, E, and F arranged on the second and third stages are connected to each other, the units A, C, E, and F on the third stage are connected to each other. As shown in FIG. C and E are arranged.
In the fourth row, the corner unit C is arranged with its position changed by 90 degrees in the counterclockwise direction. That is, the plane unit A is arranged adjacent to the corner unit C on the opposite side of the connection plate 12, and the plane unit A is disposed on the connection plate 12 side via the adjustment unit E. Placed, and
The adjusting units E are arranged in contact with the rectangular plate members 11 on both sides of the corner unit C, respectively.

As described above, each unit A,

After combining with E and F, each unit A, C,
E and F are arranged. In the fifth row, the corner units C are further arranged in the clockwise direction by changing the position by 90 degrees, return to the state of FIG. 9A, and then repeat in the same order to obtain a predetermined number of rows. Units A, C, E, and F are stacked to form a T-shaped cross section, and a structure with break joints stacked.

Next, referring to FIGS. 13 and 14, a description will be given of a procedure for forming a surface having a cross-shaped intersection. Note that the procedure for stacking and combining the units A and C is the same as the above-described configuration of the plane portion and the surface structure having the L-shaped intersection, and therefore, the arrangement method of the units A and C for each stage. And the description of the combining procedure is omitted.

As shown in FIG. 14A, the units A, C, E, and F of the first stage are arranged. This arrangement is similar to that of the T-shaped crossing portion, where the flat unit A is arranged adjacent to the width direction of the corner unit C and on the opposite side of the connecting plate 12 of the unit C, and on the connecting plate 12 side. The plane unit A is arranged via the adjustment unit F. The flat units A are arranged on both sides of the square plate 11 of the corner unit C via adjustment units E, respectively.

As shown in FIG. 17B, in the second stage,
The units A, C, E, and F are arranged while changing the position 90 degrees clockwise while maintaining the arrangement state of the units. Similarly, in the third stage, as shown in FIG. 9C, the fourth stage maintains the initial arrangement state as shown in FIG. Is located at a different position,
Each time the number of stages changes, each of the lower units A, C, E,
By combining F with the upper units A, C, E, and F, it is possible to have a cross-shaped cross section and to form a structure with break joints.

In each of the above embodiments, each of the units A to F has the core square members 2 and 3 arranged in two rows, and the spacer square members 4 are arranged between them. However, in the present invention, the core square bars 2, 3
The number of columns is not limited, and may be three or four, or one. Hereinafter, the configuration of the flat unit G in which a row of core square pieces are arranged between two rectangular plate members 1 and a structure formed using the flat unit G will be described.

As shown in FIG. 15 and FIG.
Is composed of two square plate members 1 configured in the same manner as the flat unit A described above, and core square members 2 and 3 arranged between the square plate members 1. The core square members 2, 3 are arranged so as to be spaced apart from each other by a distance slightly larger than the length of the edge of each of the core square members 2, 3 and are adhered to the rectangular plate member 1. An insertion space 5 penetrating in the height direction is formed by the plate 1.

A water return 1a is formed on the upper surface of the rectangular plate 1 along one edge, and a recess 1b is formed on the lower surface. Drainage grooves 1c are formed on both end surfaces in the width direction of the rectangular plate 1. Chamfered portions 2a, 3a are formed at the upper end portions of the core square members 2, 3, and a flat wedge 15 is driven into at least an end surface of the upper and lower end surfaces of the core square members 3 which protrudes from the rectangular plate member 1. A groove 3c formed of an I-shaped cut is formed.

In the flat unit G configured as described above, the length of the side of the fore edge of the core square members 2 and 3 is formed to be about 50 mm, the thickness of the square plate 1 is about 50 mm, and the length in the width direction is about 50 mm. 500
mm, and the length in the height direction is set to about 210 mm including the water return 1a. The protruding length of the core square members 2 and 3 from the rectangular plate 1 is set to 200 mm.

As described above, even in a construction unit in which the core square members 2 and 3 are arranged in one row between the two rectangular plate members 1,
Units similar to the units A to F having the row of core square bars 2 and 3 are configured.

That is, the flat unit G is cut at a position (center) where the length in the width direction is half of a plane perpendicular to the surface of the rectangular plate member 1 to form the half unit H. Is done.

As shown in FIG. 17, the corner unit I includes core cores 2 and 3 having one upper end protruding in the height direction of the rectangular plate 11 and arranged at the ends of the core squares 2 and 3. The distance from the outer surface on the side of the edge 11a of the square member 3 to the edge 11a in the width direction of the rectangular plate member 11 is substantially set to the thickness of the corner unit I, and the connection arranged based on the edge 11a. A plate 12 is formed by connecting the ends of two rectangular plates 11. The corner unit I includes a core square member 14 and a connecting plate member.
Communication space 13 defined by 12 and two rectangular plates 11
Are formed.

In particular, in the corner unit I, similarly to the corner unit D described above, the insertion space 5 and the communication space 13 are not arranged at substantially equal intervals. Numeral 14 designates a structure which is almost in contact with each other. A corner unit similar to the above-described corner unit C in which the core square members 2, 3, and 14 are arranged at substantially equal intervals is also configured.

Next, a construction having an intersection formed by using a flat unit G, a half unit H, a corner unit I and adjustment units J and K in which the core square members 2 and 3 are arranged in one row is shown in FIG. This will be described with reference to FIG.

In the figure, the procedure for connecting the units G to K in each of the vertically adjacent stages is the same as that for connecting the units A to F described above. Also, the order of the units G to K arranged in each stage does not change at all from the order described with reference to FIGS. That is, the units G to K and the units A to F are basically the same except that the number and dimensions of the core square members 2 and 3 are simply different. For this reason,
Even the surface structure having the intersections is the same as the above-mentioned surface structure, and it is natural that the construction method is also the same.

FIG. 19 shows a construction having two T-shaped intersections of a and b. A corner unit I is arranged at the eighth stage from the bottom of the intersection A, and a plane unit G is arranged continuously on the opposite side of the connecting plate 12 of the unit I,
A flat unit G is arranged on the side of the connecting plate 12 via an adjusting unit K. One side of the square plate 11 of the corner unit I is provided with a flat unit G via an adjustment unit J.
Is arranged. This construction surface is configured by stacking flat units G at break joints, and a half unit H is arranged at an end parallel to the length direction of the core square bar of the construction surface,
The end is formed in a straight line.

As described above, even when each of the units G to K having the core square members 2 and 3 arranged in one row is used, it is possible to form a structure in which the break ground is stacked. In addition, the corners formed by the corner units I
It is possible to connect by using.

In each of the above-described embodiments, the core
3, 14, spacer square member 4, square plate member 1 and connecting plate member 12,
The tenon 10 is all made of wood, and the squares of the core squares 2, 3 and 14 and the spacer square 4 have substantially the same shape.
Has a thickness substantially equal to the length of the side of the fore edge of the core square members 2 and 3. Furthermore, if the square plate 1 and the connecting plate 12 are configured by bonding square members having the same shape and cross section as the core square members 2 and 3 by arranging the wood fibers in the height direction and bonding them, each of the units A to K All the members are made of wooden timber having a cross section of the same shape and size as the basic material.After cutting the basic material to a desired length, each member only needs to be subjected to necessary processing and bonding to each member. , The yield of materials is increased. In addition, it is possible to use small diameter trees such as thinned wood and scrap wood, and it is possible to reduce material costs.

In each of the units A to K described above, since the square plate made of the plate made of the wood timber, the core timber made of the wood timber, and the spacer timber made of the wood timber are used, all the components are made of the wood plate. The cost can be reduced as compared with the case where a plate material having a plurality of layers is used. That is, the square lumber is a product in a stage before the production of a plate material in which a plurality of wooden plate materials are assembled, and the cost is low because the bonding for forming the plate material is omitted. Therefore, the cost of each completed unit can be reduced. In particular, when each unit is manufactured, it is possible to mass-produce units having stable accuracy by using a dedicated jig for setting the interval between core square members and the like.

As in the above-described embodiment, each of the units A to A
When joining K, since it is a dry operation without using concrete or an adhesive, the site is not contaminated. Further, even when an inclined construction surface such as a roof surface is formed, temporary support such as a concrete block structure is not required. In addition, since each unit is relatively lightweight, no heavy equipment is required for construction.

[0121]

As described in detail above, in the construction unit according to the present invention, since the core square is inserted along the rectangular plate along the entire length of the plate in the height direction, the joint strength between the units is high. For this reason, it is possible to form a highly reliable surface having high resistance to out-of-plane deformation. In particular, in a construction unit having a plurality of rows of core square members and spacer square members provided between the square member rows, more members are provided on the square plate side of the configured surface, that is, on the surface side of the surface. Is used, the second moment of area is increased as compared with a solid wall having only the same weight, and a large resistance to deformation in an out-of-plane direction is obtained.

Also, the interval between the core square bars adjacent in the row direction is
Since the clearance is secured by making it slightly larger than the width (length of the side of the fore edge) in the row direction of the core square bar, deformation such as dimensional tolerance of the core square bar, assembly tolerance of the core square bar, warpage or swelling of the core square bar. However, it becomes easy to fit the core bar of the facing unit into the core bar of another facing unit adjacent to the protruding direction of the core bar. Therefore, accuracy control during the manufacture of the surface unit becomes easy.

Further, since the width of the core bar in the row direction and the dimension of the insertion space in the thickness direction are automatically made substantially equal, the inner surface of one core bar and the inner surface of the other square plate of the structural units to be connected are frictional. The surface units can be tightly connected to each other only by the frictional force upon contact. Therefore, when performing the connecting operation of the structural units, the operation can be completed by hitting with a hammer or the like without using an adhesive or a nail. That is, special technical skills and special tools are not required for the construction, and the construction accuracy can be ensured only by simple repetitive work.

Further, a plurality of square members are used as spacer members,
Since the spacer bars are arranged at intervals in the length direction of the core bars, a sleeve space defined by the spacer bars and the core bars is formed in the interior surface unit. For this reason, the weight of the surface unit can be reduced.

[0125] By making the number of core square bars of the structural unit an odd number, when the units are arranged adjacent to each other in the longitudinal direction of the core square members, the adjacent structural units are always displaced. I can do it. Further, in forming a wall surface with a break joint, a floor surface or a roof surface with a break joint arranged thereon, or a wall surface with a break joint, a core square bar of a surface unit adjacent to the lower surface in an insertion space of the surface unit adjacent in the width direction. Is inserted, and watertightness and airtightness can be secured only by connecting a plurality of surface units.

Further, since the square plate includes the direction of the wood fiber parallel to the length direction of the core square wood, the load bearing direction such as the gravitational load acting on the structural surface is matched with the direction of the wood fiber so that the load can be reduced. Can be paid. In addition, since the shrinkage does not occur with time in the direction of the wood fiber, the formed wall surface does not change with time, and is excellent in watertightness and airtightness, and does not require long-term maintenance.

When the structural units adjacent to each other in the length direction of the core bar are connected to each other, a wedge is driven into a groove formed at an end of the core bar to expand the end of the core bar. The core square can be pressed against the inner surface of the rectangular plate and the adjacent core square. For this reason, more stable joining strength can be obtained. Especially,
Since the interval between the core squares is slightly larger than the length of the edge of the edge of the core square, the wedge can be easily driven into the wedge driving groove.

Further, there is a wedge driving groove at the end of the core square bar at the end closest to the boundary between the left and right facing units, and it is disposed above the right and left facing units. The core square bar having grooves for wedge driving of the lower left and right face unit is inserted into the insertion space on both sides of the core square bar at the center of the facing unit, and the wedge is driven into the upper square unit, whereby the core square member is moved upward. It is possible to press the core square bar at the center of the surface unit and the left and right core square bars to tightly connect the structural unit. For this reason, these structural units do not shift out of plane.

Further, a step portion for returning water is formed on the upper side surface of the rectangular plate member, and a drainage groove for drain is formed on the side surface in the width direction. Capillary phenomena in the part can be blocked to prevent water penetration.
