2. Description of the Related Art In recent years, especially since the experience of large-scale and wide-area earthquake disasters in Hanshin, earthquake countermeasures for general buildings are being renewed. However, it is also possible to use some of the relatively high cost new technologies for seismic, seismic isolation, seismic absorption, etc. that are architecturally effective for large or special purpose buildings. In practice, the overwhelming majority of general residential buildings and the like are, as a practical matter, followed by conventional construction methods without a simple method of obtaining high seismic absorption and seismic resistance at an acceptable cost. The current situation is such that seismic countermeasures are taken for interior furniture, and the situation is such that substantial seismic countermeasures for buildings have not been taken.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides an extremely cost-effective base for seismic absorption and seismic resistance (hereinafter simply referred to as "seismic resistance") for buildings. Therefore, the purpose is to realize the spread of practical seismic measures for many general houses.

It is intended to achieve the above object.

[0005]

The seismic base according to the present invention as described above is effectively used, for example, as a unit on the entire base of a general building, so that seismic measures can be spread to many general buildings.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail based on an embodiment.

[0007]

This embodiment is an example of an embodiment in which the seismic base of the present invention is constructed in a unit type, and a plurality of these units are appropriately combined to be used as a seismic base of a building.

FIG. 1 is a perspective view of a main part of the seismic base, and FIG. 2 is a sectional view taken along the lines AA and BB of FIG.
FIG. In addition, FIG. 3 shows an inner perspective view (a), an AA cross-sectional view (b) of FIG. 3 (a), and a BB cross-sectional view (c) and (a) of FIG. FIG. 4D shows an outer perspective view of FIG. 4 (a) is an inner perspective view of the seismic vent door, FIG. 4 (b) is a sectional view taken along line AA of FIG. 4 (a), and FIG. The figure is shown.

FIG. 1 shows a structure on a foundation concrete 1 of a building.
A state in which a wooden foundation for a normal building is placed on an earthquake-resistant foundation constructed by combining a plurality of earthquake-resistant foundation units 2 of the present invention, 3 is a seismic foundation unit for a corner of a building, 4 is a seismic vent door, 5 is a wooden base, 6 is a pillar of a building to be connected to the wooden base 5, and 7 is each of the seismic base units 2, 3 and the base concrete 1 and the wooden base 5 are fixedly mounted. 1 shows an adhesive to be used.

In FIGS. 2 and 3, reference numerals 8, 9, and 10 denote fasteners such as wood screws and bolts, 11 denotes a rubber packing for adjustment, and 12 denotes a fitting made of synthetic rubber.

Next, the structure of each seismic base unit 2 will be described with reference to FIG.

Each seismic base unit 2 includes a top metal plate 13 and a bottom metal plate 14 made of stainless steel or aluminum, etc., each having a flange on the outside (front) side and inside (back) side of the building. Between them, a vibration absorbing cushion material made of synthetic rubber R is filled in a comb shape between the top / bottom metal plates 13/14 in a sectional shape as shown in FIG. Spaces 15 are formed between the comb teeth.

In order to reinforce the integral bonding between the top / bottom metal plates 13/14 and the synthetic rubber R body of the cushioning material, a plurality of rectangular three-sided punched holes 16 are formed on both plate surfaces. L with the remaining sides bent inward each
The character 16a is formed so as to be buried in close contact with the molten rubber R at the time of molding.

On both sides of the unit 2, vertical grooves 17 are respectively formed in the synthetic rubber R, and both ends 18 of the ventilation opening door 4 shown in FIG. 4 are inserted between arbitrary adjacent units 2. It is configured so that it can be fixed.

The ventilation door 4 has a plurality of louver-type openings 19.
As shown in FIG. 2 (b), the upper part is mounted on the wooden base 5 with a fastener 9, and the lower part is mounted on the top of the foundation concrete 1 by a synthetic rubber fitting 12 so as to be bufferable.

Next, each of the building corner earthquake-resistant units 3 shown in FIG. 5 has the same basic configuration as each of the standard earthquake-resistant base units 2, and includes top / bottom plates 13A / 14A each having an angle plane shape. , Each side is provided with two synthetic rubber comb-shaped portions R and one space portion 15.

As described above, since the seismic base units 2 and 3 and the ventilation opening door 4 according to the present embodiment are unitized, the degree of freedom of manufacture and combination, transportation and handling of each unit are provided. It is extremely easy to do so, without having to change its main configuration to a wide variety of buildings,
The seismic function can be realized at relatively low cost.

(Other Embodiments) The configuration of the present invention is not limited to the combination of the above-mentioned unit type configurations, but this type of unit can be converted into a longer unit according to various conditions on the demand side. It goes without saying that they can be integrated or conversely subdivided to respond to special conditions.

For portions where the load distribution per unit length of the base changes, such as a one-story portion and a two-story portion of the building to be used, the allowable load and the allowable deflection in the inward and outward directions are respectively appropriate. Can be used.

The synthetic rubber used as the vibration-absorbing material is not limited to this, and natural rubber, synthetic resin materials, composite materials, etc., or any combination thereof can be used. Of course.

Further, the shape of the synthetic rubber as a cushion material of each of the seismic base units, the means for strengthening the connection with each of the top / bottom plates, the respective fastener means, and the like are limited to the embodiment shown in the figure. Of course, various modifications are possible.

[0022]

As described above, according to the present invention,
The structure is unit-combined with an example of an earthquake-resistant base mainly made of vibration-absorbing material, so that it is easy to provide earthquake resistance to a wide range of buildings easily at a relatively low cost without basically changing the conventional building structure. can do.
