BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a pad for a foundation of a wooden building of the present invention will be described below with reference to FIGS.

FIG. 1 shows a foundation pad 1. As shown in FIG. 2, this foundation pad 1 is interposed between a cloth foundation 2 and a wooden base 3 placed and fixed thereon, and has a rectangular shape made of a metal plate. A flat plate-shaped body 4,
The gap forming projection 5 is provided. The gap forming projections 5 include small-diameter projections 6 at the four corners of the flat plate-shaped body 4, large-diameter projections 7 that can be inserted through anchor bolts 17 provided in the central portion of the flat-plate-shaped main body 4, and between them. It is composed of a plurality of bowl-shaped protrusions 9 which are dispersed in the region. These small diameter protrusions 6,
The large-diameter protrusion 7 and the bowl-shaped protrusion 9 are integrally bulged downward from the flat plate-shaped body 4 in order to form a substantially constant gap between the cloth foundation 2 and the wooden base 3. Small diameter protrusion 6
Is composed of a bottomed cylindrical projection 8 having an annular wall, and a through hole 10a is formed in the center of the bottom wall 8a. The large-diameter projection 7 is formed by opening a large part of the bottom wall 8a of the bottomed cylindrical projection 8 as a large-diameter through hole 7a through which the anchor bolt 17 penetrates. Bowl-shaped protrusion 9
Is composed of a protrusion having an inclined peripheral wall integrally formed by projecting from the flat plate-shaped body 4 toward the cloth foundation 2 side. In the illustrated example, the planar shape is formed into an ellipse, and a large number of the inclined peripheral walls are formed. The thin through holes 10b are dispersedly formed.

The small-diameter projection 6 consisting of the bottomed cylindrical projection 8 and the hollow 5a formed inside the bowl-shaped projection 9 accommodate a filler 11 containing charcoal powder as a main component. Has been done. If necessary, a suitable chemical agent can be added to the filler 11 in order to enhance the hygroscopic action, bactericidal action and pest repellent action. The filler 11 may be made of powder or granules, or may be made of a molded body.
It is necessary to form a large number of thin through-holes so that the powder or granular material does not fall off.
It is only necessary to form a through hole such as the through hole 10a at the center of the bottom wall 8a, which does not allow the molded body to fall off.

On one short side of the rectangular flat plate-shaped main body 4 is formed a downwardly extending bent piece 12 over substantially the entire length excluding both ends, and on the remaining three sides, the downwardly bent piece is formed. A fitting groove 13 into which 12 can be fitted and engaged from above is formed over substantially the entire length of each side. More specifically, the other short side is formed over substantially the entire length excluding both ends, and the pair of long sides is formed over the substantially entire length except for one end on the side where the bent piece 12 is formed. The bent piece 12 constitutes the fitting portion 14, and the fitting groove 13 constitutes the fitted portion 15, respectively.
The fitting portion 14 and the fitted portion 15 constitute a connecting means 16 for arbitrarily connecting the flat plate-shaped main bodies 4 to each other in the series direction or the right angle direction.

In general use of the foundation pad 1 having the above structure, as shown in FIG. 2, the position of the anchor bolt 17 on the cloth foundation 2 and the position immediately below the wooden column 3a,
Other than that, the single foundation pads 1 are arranged at appropriate intervals L, and the wooden base 3 is arranged thereon. The appropriate distance L is appropriately about 1 m at maximum. When arranging the foundation pad 1, if necessary, the small-diameter projection 6 of the foundation pad 1 can be used to temporarily fix the foundation pad 1 to the upper surface of the cloth foundation 2 with concrete nails, or the wooden foundation 3 Similarly, the small-diameter projection 6 can be used on the bottom surface for nailing.

In addition, at the position where the anchor bolt 17 is arranged, as shown in detail in FIG.
Through the large-diameter projection 7 and the anchor bolt hole 19 of the wooden base 3 and tightened with a nut 18 to fix the wooden base 3 to the cloth foundation 2.

Thus, in the state where the wooden base 3 is placed and supported on the cloth foundation 2 via the foundation pad 1, the load acting on the wooden base 3 causes the plate-shaped main body 4 of the foundation pad 1 and the gap forming projections. 5 (6, 7, 9) is supported by the cloth foundation 2 so that there is a gap 20 between the cloth foundation 2 and the wooden base 3.
A stable supporting state can be obtained while forming the. Moreover,
Since air freely flows between the gap forming projections 5 and 5 even in the pad 1, the air permeability is ensured, and the thickness of the foundation pad 1 is not increased more than necessary. It is possible to secure an opening area required for underfloor ventilation while making the gap 20 between the wooden base 3 and the space 3 relatively small, and it is effective in preventing the wooden base 3 from decaying.

A large load is often applied to the T-shaped crossing portion of the cloth foundation 2, and in that case,
As shown in FIG. 4, the first and second foundation pads 1, 1 are connected in series by the connecting means 16, and the third foundation pad 1 is connected in a direction perpendicular to the connecting portion. As a result, the load can be dispersed and supported by the three foundation pads 1 that are connected to each other in a T shape. Or
As shown in FIG. 5, by connecting the second foundation pad 1 at right angles to the central portion of the long side of the first foundation pad 1, the load is dispersed by the two foundation pads 1. You can also support. In addition, even if a plurality of foundation pads 1 and 1 are connected in this manner, air freely flows between the gap forming projections 5 and 5 in the portion of the pad 1 as described above to ensure air permeability. Therefore, it is possible to prevent the wooden base 3 from decaying. Although not shown, the same applies to the cross-shaped intersection.

Similarly, in the L-shaped corner portion of the cloth foundation 2, as shown in FIG. 6, one end side where the bent piece 12 of the first foundation pad 1 is arranged is a corner portion. And the second foundation pad 1 is connected to the one end side thereof at a right angle so that the load is dispersed and supported by the pair of foundation pads 1 connected to each other in an L shape. You can

Since the fitting groove 13 along the long side of the foundation pad 1 is not formed at one end where the bent piece 12 is formed, the foundation pads 1 and 1 are connected at a right angle. In doing so, the fitting grooves 13 do not interfere with each other.

Further, in this embodiment, the gap forming projections 5 are composed of a plurality of small diameter projections 6 around the flat plate-shaped body 4, a large diameter projection 7 at the center and a bowl-shaped projection 9. Because
The load can be dispersed and supported by the entire flat plate-shaped body 4, the central large-diameter projection 7 can be used as an insertion hole for the anchor bolt 21, and when an impact load is applied during an earthquake or the like, The small-diameter projections 6 and the large-diameter projections 7 in the portions to which an excessive load is applied bite into the cloth foundation 2 so that the bowl-shaped projections 9 having the inclined peripheral wall are elastically deformed and finally buffered by buckling deformation. The fatal damage of the wooden structure can be prevented by dispersing and absorbing the excessive load.

In addition, since the filler 11 containing the charcoal powder as the main material is housed in the hollow portion 5a of the gap forming protrusion 5, the wooden base 3 and the flat plate-shaped body 4 are filled with the filler 11. Even if dew condensation occurs on the contact surface, it can be dried by the hygroscopic effect of charcoal powder, and it also has antiseptic and pest repellent effects, so it is corroded by corrosive bacteria and pests form nests. Can be reliably prevented. Furthermore, it is more effective if a drug that enhances their action is added.
Of course, the fillers 11 having different functions may be housed in the hollow portions 5a of the gap forming protrusions 5, respectively. Further, depending on the place of use, only the filler 11 having any one of the functions of moisture proof, antiseptic, and pest repellent may be housed in the hollow portions 5a of all the gap forming projections 5. Further, since the through hole 10a is formed in the small diameter protrusion 6 and the through hole 10b is formed in the bowl-shaped protrusion 9, it is possible to effectively release the absorbed moisture and the medicinal component to the surroundings.

In the above embodiment, the flat plate-shaped main body 4 has a rectangular shape, and the fitting portion 14 including the bent piece 12 on one short side thereof.
Although the example in which the fitted portion 15 including the fitting groove 13 is formed on each of the remaining three sides is shown, the specific configurations of the fitting portion 14 and the fitted portion 15 are limited to these. Alternatively, the fitting portion 14 may be formed on any one side of the rectangular flat plate-shaped body 4 and the fitted portion 15 may be formed on at least one of the remaining three sides.

Further, in the above-mentioned embodiment, the example in which the foundation pad 1 is interposed between the wooden base 3 and the cloth foundation 2 is shown, but the wooden pillar 3a is directly attached to the wooden foundation 3 instead of the wooden base 3 or a part thereof. Even in a support structure that is placed on and supported by 2
By similarly interposing the foundation pad 1 between the wooden pillar 3a or the wooden foundation 3 and the cloth foundation 2, the same operation and effect can be obtained.

[0022]

The foundation pad member of the present invention can be embodied as described above, and includes a rectangular flat plate-like main body, a gap forming projection protruding from the flat plate-like main body, and a flat plate-like body. Since it has a connecting means for connecting the main bodies to each other in a serial direction or a right-angled direction, a plurality of connecting means are connected to the area where a large load acts between the wooden base or the wooden pillar and the cloth foundation by the connecting means. By interposing the foundation pads, the load can be effectively dispersed and supported by the plurality of foundation pads connected to each other, and since the flat plate-shaped main bodies are connected to each other by the connecting means, a plurality of base pads are connected. The foundation pads can be handled together and easily and properly positioned.

Further, the connecting means has a fitting portion formed on one side of the flat body and a fitted portion formed on at least one of the remaining three sides, Since they are fitted and connected to each other, they can be easily connected.Because the gap forming projections are projected from the flat body, air freely flows between the gap forming projections. , Even if a plurality of foundation pads are connected and arranged as described above, the air permeability is ensured at those pads, so make the thickness of the foundation pad thicker than necessary and between the foundation and the cloth foundation. The opening area required for underfloor ventilation can be secured without increasing the gap between the floor and the wooden base etc. does not easily corrode at the contact area with the pad due to poor ventilation. The effect such as being able to be exhibited.

Further, the flat plate-shaped main body is rectangular, the fitting portion of the connecting means is formed on the short side of the main body, and the fitted portion is formed on each of the remaining three side sides of the main body. It is possible to connect to any shape along the L-shaped corner portion or the T-shaped or cross-shaped crossing portion by using the above-mentioned foundation pad.

The fitting portion is formed by a downward bent piece on the side of the flat plate-shaped body, and the fitted portion is formed by a fitting groove of the downward bent piece formed on the side of the flat body. With this configuration, it is possible to connect the side edges of the flat plate-shaped body by simply stacking them on top of each other, and it is possible to easily form the flat plate-shaped body at the time of molding.
