DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for a building base.

[0002]

2. Description of the Related Art Conventionally, a pad made of a rubber material or a piece of wood is interposed between a cloth foundation and a base of a wooden building.
A gap is formed between the fabric foundation and the base, and the underfloor ventilation holes to be installed on the fabric foundation are omitted, and this gap provides effective underfloor ventilation and prevents absorption of water and moisture from the foundation concrete. The base was quickly dried to prevent corrosion of the base.

[0003] However, such a conventional pad has a drawback that stable support of a base and a buffering effect at the time of an earthquake or the like cannot be combined.

[0004] In order to eliminate such defects, for example, Japanese Patent Application Laid-Open Nos. 9-67871 and 9-1.
No. 25535, JP-A-9-125536, JP-A-9-125
JP-A-137514, JP-A-9-137515, JP-A-9-137
Japanese Patent Application Laid-Open No. 296455/1998 and Japanese Patent Application Laid-Open No. 10-219856 have been made, but these spacers have relatively complicated structures and are expensive.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a spacer which has eliminated the disadvantages of the above-mentioned known example.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a substrate having a predetermined shape, wherein a hook portion is provided at one end of the substrate and a hook portion is provided at the other end of the substrate. A number of convex portions having a concave shape with an inclined surface formed around the bottom surface are provided. A drain hole and a lower protrusion are provided on the bottom portion of each of the convex portions, and an upper protrusion is provided between the convex portions of the substrate. Is provided.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Now, a main board and a sub board are arranged at predetermined positions on a cloth foundation concrete. The main board and the sub-board are connected to each other at the right place on the base concrete by the hooking part and the hooking part, and the anchor bolt holes at the center of each board are erected on the base concrete. Insert the anchor bolt.

[0008] Under such a condition, a base wood may be placed on each substrate.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a main substrate having a rectangular shape as a whole. A hook portion 2 is provided at one end in the longitudinal direction of the main substrate, and a hook portion 3 is provided at the other end.

Reference numerals 4 and 4 denote reinforcing bent portions provided on both lateral ends of the main substrate 1 in the lateral direction.

5, 5,... Are projecting portions provided at equal intervals in two rows in the longitudinal direction of the main substrate 1, and the projecting portions form an inclined surface around from the flat surface to the bottom surface. It has a concave shape.

Reference numeral 6 denotes a drain hole provided on the bottom surface of each protruding portion 5 of the main substrate 1, and lower projections 7, 7 projecting downward across the drain hole are provided. The lower protrusion naturally penetrates into the foundation concrete portion a depending on the weight of the building.

Reference numeral 8 denotes a mounting hole for the foundation concrete part a.

Reference numeral 9 denotes the protrusions 5 on the main substrate 1.
The upper protrusions protrude upwards between the 5..., And the upper protrusions naturally bite into the base material due to the weight of the building.

Reference numeral 10 denotes an anchor bolt hole provided at the center of the main board 1, into which an anchor bolt b provided on the foundation concrete side is inserted.

Reference numeral 11 denotes a sub-substrate having a square shape as a whole. A hook 12 is provided at one end of the sub-board, and a hook 13 is provided at the other end.

Reference numerals 14 and 14 denote reinforcing bent portions provided on the other side ends of the sub-substrate 11.

Reference numerals 15, 15,... Denote protrusions provided at equal intervals in two rows on the sub-substrate 11, and the protrusions have a concave shape having a peripherally inclined surface from the flat surface to the bottom surface. .

Reference numeral 16 denotes a drain hole provided on the bottom surface of each protruding portion 15 of the sub-substrate 11, and provided with lower projections 17, 17 protruding downward across the drain hole. The lower protrusion naturally penetrates into the foundation concrete portion a depending on the weight of the building.

Reference numeral 18 denotes a mounting hole for the foundation concrete part a.

Numeral 19 is an upper projection protruding upward between the projections 15, 15,... On the sub-substrate 11, and this upper projection will naturally bite into the base material due to the weight of the building.

Reference numeral 20 denotes an anchor bolt hole provided in the center of the sub-board 11, into which an anchor bolt b provided on the foundation concrete side is inserted.

[0023]

According to the spacer of the present invention placed on the foundation concrete, the base is supported by a large number of box-shaped projections formed on the substrate, so that the weight of the building is strongly increased. In addition to being able to support, the necessary underfloor ventilation port can be formed, and since the structure is relatively simple, the manufacturing cost can be reduced.
