Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base structure for a building, and more particularly to a base structure for a floor, a wall or a ceiling in a structure.

[0002]

2. Description of the Related Art For example, as a floor base structure for a building, there is one using a Japanese industrial standard JIS A6519 steel floor base material for a gymnasium. Further, there is also known a floor base material having a special structure developed for an OA floor such as a computer room. Further, as a floor substructure of a building (particularly for general houses), a wooden Daibiki is arranged on an underfloor slab, a wooden joist is arranged on the Daibiki, and a floor material is arranged on the wooden joist. In this case, as a measure against termites, it is often the case that wooden daiiki and joists are soaked with a chemical for termite control.

By the way, in recent years, attempts have been made to increase the number of effective floors by reducing the height of each floor in a building (in particular, a high-rise building). Is required.

However, in the case of the above-mentioned floor substructure using the steel floor substructure for a gymnasium, since it is limited to a gymnasium, it is difficult to lower the floor because of its structure, and it lacks versatility. There is a problem that it is generally difficult to spread because of its high cost.

Further, in the OA floor, many supporting members having a complicated structure are provided between the underfloor slab and the floor material, and the connecting portion between each supporting member and the floor material is arranged. Is a structure in which the lower surface of the floor material is specially processed and the upper end of the support member is fitted, so the structure is inevitably complicated and the number of parts and processing man-hours increase, which inevitably leads to cost increase. There is a problem. In addition, workability is deteriorated because it takes a lot of time and effort to adjust the height of each support member. Moreover, since it is exclusively for the OA floor, it lacks general versatility, and there is a problem that it is difficult to popularize it in general.

[0006] Further, when a floor substructure is constructed by a combination of wooden haul and joists, there is a limit to lowering the floor substructure, and the construction itself becomes complicated, and the assembling work must be complicated. There is a problem of not getting. Moreover, there is also a problem that simply impregnating the used wood with chemicals is not a complete countermeasure against termites.

[0007] One of the main reasons why metal floor substrata are not used in general houses is that carpenters do not like to use them due to their complicated structure and construction method.

As a base structure for puffed walls in a building, a W bar used for a ceiling or the like is fitted at a predetermined interval into a pair of runners arranged vertically along a wall slab, and an intermediate portion of each double bar. Is fixed by shaving or using screws with a metal fitting, and multiple fixing devices for fixing the W bar to the wall slab without using a runner are arranged at points in a predetermined position and placed on a straight line. W-bars are fixed to the fixing devices lined up in line with each other, conventional steel square pillars are fitted to the upper and lower runners, and the special-structure rails are fixed orthogonally to the wall slab corresponding to the middle part, A special clip fitted to the rail and a conventional steel square column are fixed with screws, a wall slab is pasted with glue, and a top board is directly pasted onto it (generally called the GL method) ing There is.

However, in the case of the conventional puffer wall base structure described above, all of the prior arts (1) to (3) require a lot of time and labor for the construction work, and the cost increase is avoided because various parts must be combined. There is a problem of difficulty. Moreover, in the foundation structure for puffed walls, it is desirable to make the puffed width from the wall slab (that is, the distance between the wall slab and the overlaid board) as small as possible. There is also a problem that there is a limit. In addition, in the above-mentioned conventional technique, although the puff width can be made small, since the glue is used, if the drying time is not taken long, there is a problem that mold is generated on the surface of the top-pasted board and the wall surface is leveled. Also has the problem of requiring skill.

As a base structure for a ceiling in a building, a hanging bolt is screwed into an insert already installed in a ceiling slab, a hanger is fixed to the lower end of the hanging bolt, and a hoop receiver (that is, a channel) is attached to the hanger. Which are fitted to each other and fix single or double fields to the field frame with clips, and a conventional steel square column for a pair of runners arranged at both ends of the ceiling slab. There is one that fits at a predetermined interval.

However, in the case of the above-mentioned conventional base structure for a ceiling, in the prior art, the assembly process is extremely complicated,
There is a problem that the number of types of parts is inevitably large, the construction requires a lot of labor, and the construction requires considerable skill. Further, in recent condominium construction and the like, a shallow ceiling is required to increase the room area as much as possible, but the conventional technique has a problem in that the ceiling cannot be made shallow due to structural limitations. Further, in the prior art, since there is no fixing means in the middle part, it can be applied to a narrow ceiling width (for example, within about 1.5 m), but when the ceiling width becomes wider, the middle part is lowered. There is a problem that it may drip and it is difficult to apply.

[0012]

Under the circumstances described above, a metal base material fixed to the slab by fixing pins is provided between the interior material and the slab in a parallel state at a predetermined interval. Expectations are increasing for a groundwork structure for buildings constructed by interposing.

This foundation structure for a building has a very simple structure and can be constructed at a low cost without requiring any special technique, but it is technically difficult to make the surface of the slab flat, A member for filling the gap between the base material and the slab and for horizontally adjusting or vertically adjusting the base material is required.

It is conceivable to prepare a plurality of plate materials having different thicknesses as the above-mentioned horizontal or vertical adjusting members and perform horizontal adjustment or vertical adjustment by combining these, but many plate materials having different thicknesses are prepared in advance. There is a problem that the number of parts must be increased and the combination of the plate materials must be decided on site, resulting in poor workability.

The present invention has been made in view of the above points, and in a building structure for a floor, a wall or a ceiling, horizontal adjustment or vertical adjustment of a base material is performed.
It is an object of the present invention to make it possible to carry out extremely easily and with good workability with a small number of parts.

[0022]

In the basic configuration of the present invention, the following actions can be obtained by the above means.

That is, with the base material 3 placed on the slab 2, the adjustment piece 1 is placed in the gap between the base material 3 and the slab 2.
By disposing 1, 12 and sliding both adjusting pieces 11, 12 along the tapered surfaces 11a, 12a, the contact state between the two (that is, the degree of polymerization of the tapered surfaces 11a, 12a)
Accordingly, fine adjustment of the gap (that is, horizontal adjustment or vertical adjustment of the base material 3) can be easily performed. At this time, the adjusting pieces 11 and 12 are prevented from being displaced in a direction other than the sliding direction due to the fitting sliding action of the convex strip 15 and the concave groove 16, and smooth slide adjustment can be performed.

That is, of the adjusting pieces 11 and 12, the adjusting piece 11 located on the side of the base material 3 has a mark reference end 17 formed at the leading end in the sliding direction and partially cut away so as to be orthogonal to the sliding direction. , The mark reference end 1
In the case where the positioning projection 18 which is projected from 7 and serves as a fastening portion of the positioning fastening piece 19 that joins the both adjustment pieces 11 and 12 is formed, after the horizontal adjustment or the vertical adjustment by the adjustment pieces 11 and 12. Therefore, before co-sewn with the fixing pin 8, the positioning reference mark is marked on the adjustment piece 12 located on the slab 2 side based on the mark reference end 17, and then the positioning reference mark and the mark reference end 17 are aligned for positioning. By connecting the adjusting pieces 11 and 12 from the protrusion 18 with the positioning stoppers 19, the positioning of the adjusting pieces 11 and 12 can be easily performed.

Further, on the back side of both the adjusting pieces 11 and 12, concave portions 34 and 30 formed by hollowing out the central portions thereof are formed.
When each is formed, it is possible to prevent the adjustment pieces 11 and 12 from being cracked, which may be caused by an impact force when the fixing pin 8 is driven.

A robust base structure can be obtained by the structure and the work.

Further, the base material 3 has a U-shaped cross-sectional shape in which the slab 2 side is opened and the width of the slab 2 side from the interior material 1 side is narrowed, and the base material 3 is elongated at both ends on the slab 2 side. When a metal member having flanges 25, 25 for mounting fixed pins that are continuous in the direction is formed, the width of the base material 3 on the slab 2 side is narrow, so the length of the adjustment pieces 11, 12 in the sliding direction is reduced. The adjustment slide amount (in other words, the height adjustment amount) can be secured without increasing the length, and the flange portion 2
The base material 3 can be easily fixed by driving the fixing pins 8 into 5, 5, and a solid base structure can be obtained by an extremely simple structure and work.

Further, the base material 3 is a metal square tube having an opening 26 continuous in the longitudinal direction on the end face 3b on the slab 2 side, and a fixing pin straddling the longitudinal edge of the opening 26. Mounting plates 27 for mounting are arranged at predetermined intervals, and a plurality of cutout holes 7 used as working holes are formed in the end face 3a of the base material 3 on the side of the interior material 1 corresponding to the mounting plate 27. In this case, by using the cutout hole 7 as a work hole, the base material 3 and the slab 2 are joined by the fixing pin 8 via the mounting plate 27 at a position corresponding to the cutout hole 7 by an extremely simple structure and work. A solid foundation structure can be obtained.

Tapered surfaces 11a, 1 of the two adjusting pieces 11, 12
Since the ridge 15 and the concave groove 16 which extend in the sliding direction and are slidably fitted to each other are formed on the 2a, both adjustments are performed while utilizing the fitting sliding action of the ridge 15 and the concave groove 16. The pieces 11 and 12 are tapered surfaces 11a,
By sliding along 12a, the contact state between the two (that is, the degree of polymerization of the tapered surfaces 11a, 12a of each other)
Therefore, fine adjustment of the gap (that is, horizontal adjustment or vertical adjustment of the base material 3) can be easily performed, and smooth slide adjustment can be performed while preventing deviation of the both adjustment pieces 11 and 12 in directions other than the slide direction. There is an excellent effect that it can be done.

Further, since the adjustment can be performed only with the pair of adjusting pieces 11 and 12, the number of parts can be reduced as compared with the prior art, and the working time and cost required for the construction can be greatly reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1 FIGS. 1 to 8 show a building base structure according to Embodiment 1 of the present invention.

The building base structure of the present embodiment is a floor base structure, and as shown in FIGS. 1 and 2, is made of an interior material (hereinafter referred to as a floor material) 1 and concrete. It is configured by interposing a base material 3 made of a hollow metal square tube between the floor slab 2 and the floor slab 2 at a predetermined interval in a horizontal state in a parallel state.

The base material 3 is formed by bending a metal plate cut into a predetermined width into a square tube shape so that both ends contact each other at one corner, and one end of the metal plate is provided. Is provided with an inverted J-shaped bent portion 5 formed by bending the inside of the base material 3 and further bending the tip end of the inside toward the outside. The other end of the metal plate has an inside An inverted U-shaped bent portion 6 formed by being bent in an inverted U shape is provided, and both are continuously fitted and pressure-bonded to each other to form a corner-type connecting portion 4 which is continuous in the vertical direction. And this base material 3
Is arranged so that the corner-type connecting portion 4 is located above,
The floor material 1-side end surface (hereinafter, referred to as an upper surface in this embodiment) 3a is a surface to which the floor material 1 is attached, and the slab 2-side end surface (hereinafter, referred to as a lower surface in this embodiment) 3b is an adjustment piece 11, 1 described later.
It is supposed to be a connecting surface with the slab 2 via 2. According to this structure, since the base material 3 can be composed of a thin metal plate, a lightweight, robust, and low-cost floor base structure can be obtained, and the impact when the base material 3 and the slab 2 are joined is a corner type. The connection portion 4 is less affected.

On the upper surface 3a of the base material 3, a plurality of cutout holes 7 are formed at predetermined intervals in the longitudinal direction. The notch hole 7 is used as a working hole for inserting a nailing gun for driving a fixing pin (concrete pin 8 in this embodiment) when the base material 3 and the slab 2 are joined. It is sufficient that the opening area is such that a nail gun can be inserted, and the shape thereof can be appropriately selected from the rectangular shape shown in the figure. At both ends of the base material 3, the end face openings 9 in the corresponding portions are used as working holes.

A plurality of lower surfaces 3b of the base material 3 and the slabs 2 are provided at the rim of the end face opening 9 and below each of the notched holes 7 (in the present embodiment, orthogonal to the longitudinal direction of the base material 3). The concrete pins 8 are connected through two concrete pins 8 arranged in the direction
Between the head portion 8a and the lower surface 3b of the base material 3, a metal pressing plate 13 and a buffer plate 14 made of hard synthetic rubber, which are common to the concrete pins 8 and 8, are provided. The metal pressing plate 13 has a width substantially the same as the width of the lower surface 3b of the base material. When the concrete pin 8 is driven, the metal pressing plate 13 receives the head 8a of the concrete pin 8 and the lower surface 3b of the base material. It acts to hold down and contributes to strengthening the degree of bonding between the base material 3 and the slab 2. Further, the buffer plate 14 has a function of preventing the generation of floor squeezing which may occur due to contact between metals.

Further, in this embodiment, the base material 3 is used.
A plurality of beads 10 extending in the vertical direction are formed on both side surfaces 3c, 3d of the same at predetermined intervals in the longitudinal direction. The beads 10, 10, ... Are the side surfaces 3c, 3 of the base material.
It is composed of a vertically elongated groove formed by indenting a part of d. With such a configuration, the load resistance of the base material 3 is improved, and the one that can withstand the same load can be made thin, and the one having the same thickness can increase the force to withstand the vertical load, resulting in cost reduction. It leads to reduction. The bead 10 need not be formed when the rigidity of the base material 3 is sufficiently obtained.

Between the lower surface 3b of the base material 3 and the slab 2, a pair of upper and lower adjusting pieces 11 and 12 which are sewn together by the concrete pin 8 and contact each other with tapered surfaces 11a and 12a are slidable. Is installed in. The adjustment pieces 11 and 12 have tapered surfaces 11a and 12
The lower adjustment piece 12 positioned on the slab 2 side has a wedge shape in which the anti-tapered surfaces are abutted against each other at a and parallel side surfaces 11b and 12b are parallel to each other.
It is preferable to paste the slab 2 in advance. The material of the adjusting pieces 11 and 12 is the tapered surface 1 of both.
It is desirable to use a hard low-foam synthetic resin plate because the sliding contact resistance at 1a and 12a can be reduced. This adjustment piece 1
Reference numerals 1 and 12 serve to horizontally adjust the base material 3 by filling a gap between the slab 2 and the base material 3 by a slide polymerization degree in a state where the tapered surfaces 11a and 12a are in contact with each other.

At both ends of the adjusting pieces 11 and 12 in the sliding direction, the ridges 15 and 15 and the groove 1 extending in the sliding direction and slidably fitted to each other are formed.
6 and 16 are formed (see FIG. 3). Further, in the case of the present embodiment, the lengths of both adjusting pieces 11, 12 in the sliding direction are the same, and the upper adjusting piece 1
At the tip of the slide direction 1, mark reference ends 17, 17 are formed by partially cutting both side ends of the slide direction so as to be orthogonal to the slide direction, and a positioning projection protruding from the mark reference ends 17, 17. And 18 are formed. The slide-direction rear end of each of the ridges 15 is formed as a horizontal portion 15a that is cut off horizontally, so that the ridges 15 and the slab 2 come into contact with each other at the initial sliding stage of the upper adjustment piece 11. It is supposed to be avoided.

The mark reference ends 17 and 17 are references for providing positioning reference marks on the lower adjustment piece 12 when the alignment of the upper and lower adjustment pieces 11 and 12 is completed during horizontal adjustment by the upper and lower adjustment pieces 11 and 12. It will be. On the other hand, the positioning projection 18 is for connecting both adjustment pieces 11 and 12 by screwing a screw 19 which is a positioning stopper from the positioning projection 18 after positioning the both adjustment pieces 11 and 12. Is.

On the back surface of the upper adjusting piece 11, as shown in FIG.
As shown in FIG. 5, a recess 34 is formed by hollowing out the central portion into a rectangular shape while leaving the outer peripheral portion (in other words, the outer peripheral portion as the parallel surface 12b). In the case of the present embodiment, the positioning projection 18 in the recess 34 is
The side is open.

On the other hand, on the back surface of the lower adjusting piece 12, as shown in FIG. 5, the outer peripheral portion is left (in other words,
A concave portion 30 is formed by hollowing out the central portion into a rectangular shape (with the outer peripheral portion serving as the parallel surface 12b). Due to the presence of the recess 30, even if the surface of the slab 2 is not flat, the contact state by the parallel surface 12b can be well ensured. Further, since the recesses 34 and 30 formed on the back surfaces of both the adjusting pieces 11 and 12 can obtain an average wall thickness, it is possible to prevent cracking when the concrete pin 8 is driven.

Further, at the central portions of both ends of the lower adjusting piece 12 in the sliding direction, center positioning 31, 32 for setting the center of the lower adjusting piece 12 is provided. Reference numeral 33 is an air vent groove for venting air from the recess 30.

With the above construction, when the vertical adjustment pieces 11 and 12 are slid on each other, the projections 15 and 15 and the recessed grooves 16 and 16 are fitted and slid to each other in a direction orthogonal to the sliding direction. The positional deviation can be prevented, the horizontal adjustment of the base material 3 can be smoothly and quickly performed by the vertical adjustment pieces 11, 12, and the positioning and the positioning projections 18 by the mark reference ends 17, 17 can be performed.
The horizontal adjustment of the base material 3 becomes extremely easy by the positioning connection of the vertical adjustment pieces 11 and 12 by.

Next, a procedure for assembling the base structure according to this embodiment will be described.

First, a plurality of base materials 3 are arranged on the slab 2 in parallel at a predetermined interval, and the base material 3 is made from the end face opening 9 and the notch hole 7 with a concrete pin 8 using a nailing gun.
Is fixed on the slab 2, but at this time, the base material 3
Is adjusted in advance by the following procedure using the vertical adjustment pieces 11 and 12.

The above-mentioned horizontal adjustment is performed by the procedure shown in FIG.

First, as shown in FIG. 6A, the base material 3
Are fixed to the slab 2 in the vicinity of the end face openings 9 and 9 and between the cutout hole 7 and the slab 2 in advance by gluing or adhering, and are positioned at both ends of the base material 3. The upper adjusting piece 11 is slid to fit the ridges 15 and 15 of the upper adjusting piece 11 into the concave grooves 16 and 16 of the lower adjusting piece 12, and the base material 3
And the slab 2 are filled in and the horizontal adjustment of the base material 3 is performed. Then, when the horizontal adjustment of the base material 3 is completed, a positioning reference mark is marked on the tapered surface 12a of the lower adjustment piece 12 with the mark reference ends 17, 17 of each upper adjustment piece 11 as references. At this time, the metal pressing plate 13 and the cushioning plate 14 are fixed to the places defined as a set by lapping or bonding.

Next, as shown in FIG. 6B, the vertical adjustment pieces 11 and 12 located at both ends of the base material 3 are positioned while aligning the mark reference ends 17 and 17 with the positioning reference mark. They are joined by screws 19 screwed from the projecting portion 18, and the concrete pin 8 is driven from the rear end face opening 9 using a nailing gun from above the metal pressing plate 13 to slab the base material 3 together with the adjusting pieces 11 and 12. Co-sew on top of 2. At this time, since the upper and lower adjusting pieces 11 and 12 are coupled by the screw 19, even if an impact from a nailing gun is applied, the adjusting pieces 11 and 1 are adjusted.
2 does not shift in the sliding direction, and horizontal adjustment does not occur.

When the base material 3 can be horizontally adjusted as described above, as shown in FIG. 6C, the lower part of the cutout hole 7 in the base material 3 and the lower adjusting pieces 12, 12 ,. Each lower adjustment piece 1 so as to fill each gap created between
The upper adjustment piece 11 is slid while fitting the ridges 15 and 15 into the concave grooves 16 and 16 of the second reference mark 1
Fill in the positioning reference marks by 7 and 17.

Next, as shown in FIG. 6D, the vertical adjustment pieces 11 and 12 located below the cutout hole 7 are positioned and joined in the same manner as described above, and then a nail gun is used from the cutout hole 7. The concrete pin 8 from above the metal pressing plate 10 and the base material 3 is adjusted vertically.
Together with 1 and 12, they are sewn together on the slab 2.

In the above procedure, the metal pressing plate 13 presses the lower surface 3b of the base material 3 by the impact force applied to the head 8a of the concrete pin 8 and the compressing force acts on the buffer plate 14, but the buffer plate 14 is buffered after the connection. The reaction force from the plate 14 acts on the concrete pin head 8a, so that the coupling force by the concrete pin 8 is increased. Moreover, in the case of this embodiment, the vertical adjustment piece 1
The ridges 15 and 15 and the ridges 16 and 16 are formed at both end portions in the sliding direction of the ridges 1 and 12, and the recesses 34 and 30
Since the averaging of the wall thickness is achieved by forming the, the upper adjusting piece 11 will not be cracked by the impact force when the concrete pin 8 is driven.

As shown in FIG. 7A, the height adjustment range of the upper and lower adjustment pieces 11 and 12 is as shown in FIG.
The height Tmax in a state where 1, 12 are superposed over the entire length in the sliding direction (that is, a state in which the tip of the positioning projection 18 coincides with the end of the lower adjustment piece 12 in the sliding direction),
As shown in FIG. 7B, the height Tmin is a range in which the mark reference end 17 of the upper adjustment piece 11 is aligned with the side surface 3d of the base material 3.

As shown in FIG. 8, when a base material 3 having a low height H is used, it is difficult to insert a nailing gun from the end face opening 9, so that the floor of the base material 3 is difficult to insert. A notched hole 7 having an open end is formed as a working hole at the end in the longitudinal direction of the end face on the material side (that is, the upper surface 3a).
The concrete pin 8 may be driven in by inserting a nailing gun from above.

As described above, in the base structure of the present embodiment, horizontal adjustment of the base material 3 can be extremely easily obtained by the degree of polymerization of the pair of adjusting pieces 11 and 12, and the ridges 15 can be obtained.
Since the displacement of the sliding operation can be prevented by the fitting sliding action of the groove 16 and the groove 16, the horizontal adjustment can be easily and quickly achieved with an extremely small number of parts.

Further, the base structure obtained as described above can be completed by an extremely simple structure and work, and is robust and low in cost. In addition, even a worker (for example, a carpenter) who does not have a special technique can easily perform the construction, and the floor can be easily reduced.
