2 are fastened by anchor bolts 104 or the like in order to assemble them firmly. In addition, it is necessary to ventilate under the floor of the building in order to prevent corrosion of the base 102 and the like due to moisture from the ground. For this purpose, an opening is provided in a part of the cloth foundation 101 and the ventilation opening 105 is formed. .

[0003]

However, in the case of a structure in which a ventilation hole is provided in the basic component as described above, there is a problem that the strength and durability of the basic component are reduced by the ventilation port. For this reason, for example, a crack is generated in the base component at the location where the ventilation opening is formed. In addition, since recent earthquakes have caused enormous damage to private houses, buildings with high strength and high durability are particularly desired for private houses.

An object of the present invention is to provide a building having high strength and high durability and a method of building the same.

Embodiments of the present invention will be described below in detail. In FIG. 1, this building is composed of a base component 10, a laminated rubber material 2 fixed on the top of the base component 10.
0, a base 30 attached to the upper part of the laminated rubber material 20, a column member 40 combined on the base 30, and the like.

Referring to FIG. 2, the base component 10 is a pile 11 made of concrete or steel pipe in the example shown in FIG.
And a concrete part 12 for level adjustment provided on the upper part of the pile 11, a cylindrical form 13 provided on the outer periphery of the concrete part 12, and the like. The formwork 13 is used for pouring the concrete portion 12 into a predetermined shape, and is removed after the concrete portion 12 is cast. Further, the pile 11 is piled on the ground G such that the upper portion thereof is higher than the ground surface L by a required dimension.

The laminated rubber material 20 is formed by integrally laminating one or more sheets of synthetic rubber and a plate material 23 such as an iron plate or a lead plate between metal members 21 and 22 such as an iron plate or a lead plate. It is configured to be sandwiched. The metal members 21 and 22 are formed with holes 21a and 22a through which anchor bolts 14 and bolts 24 for fixing the laminated rubber material 20 to the base component 10 or the base 30, respectively, pass.

Further, the base 30 uses an H-shaped steel in the example shown in FIG. The base 30 has a hole 30a in which a bolt 24 for fixing the laminated rubber material 20 is stopped. The bolt 24
Alternatively, the base 30 may be fixed to the laminated rubber material 20 with concrete nails.

FIG. 3 shows an example of a main part of a building using the basic components 10 and the like according to the embodiment configured as described above. In this example, the column member 40 is installed on the base 30 via the metal bracket mounting hardware 41, and a wooden base material 42 is arranged on the side of the base 30. A configuration is provided in which a metal draining member 43 is provided. Furthermore, concrete 45 is cast on the surface of the ground G, the space between the base 30 and the concrete 45 is defined as an underfloor ventilation port 44, and a rat-proof net is provided in the underfloor ventilation port 44.

Next, a building construction method according to the embodiment is shown in FIG.
This will be described with reference to FIG. This building method is performed in first to fourth steps. First, in the first step, the pile 11 is driven into the ground G. In this case, the upper part of the pile 11 is set to be higher than the ground surface by a required dimension. The dimensions (diameter and length) of the pile 11, the method of placing the pile 11, the depth of embedding the pile 11, and the like are appropriately adjusted according to the ground survey result, the shape and scale of the building, and the like. Moreover, by forming the concrete part 12 integrally at an appropriate height on the upper part of the pile 11,
The level adjustment of the basic constituent material 10 is appropriately performed. Further, a laminated rubber material (with anchor bolts) 20 is previously mounted on the upper portion of the concrete portion 12. The concrete part 1
An anchor bolt 14 may be mounted in advance on the upper part of 2.

Here, the formation of the concrete portion 12 is performed, for example, according to the procedure shown in FIG. That is, first, FIG.
As shown in FIG. 5 (a) to FIG. 5 (b), a cylindrical form 13 is provided on the upper part of the pile 11, and concrete is poured into the form 13. Next, as shown in FIG. 5C, a laminated rubber material (with anchor bolts) 20 is installed and fixed on the upper portion. Note that the anchor bolts 14 may be provided, the laminated rubber material 20 may be provided thereon, and the anchor bolts 14 may be used for fixing.

Next, in the second step, after the foundation members 10 such as the pile 11 and the concrete portion 12 are cast, the laminated rubber material (with anchor bolts) 20 is fixed as described above. Further, the laminated rubber material 20 may be directly tightened and fixed by the anchor bolt 14. The dimensions and number of the anchor bolts 14, the thickness of the laminated rubber material, and the like are appropriately changed depending on the shape and scale of the building.

In the third step, as described above, after the laminated rubber material (with anchor bolts) 20 or the laminated rubber material 20 is mounted on the basic constituent material 10, as shown in FIG. The base 30 is mounted on the laminated rubber material (with anchor bolts) 20 or the laminated rubber material 20, and the bolt 24
Kindly fixed. Further, in the fourth step, the column members 40 constituting the first floor are sequentially combined and fixed to the base.

FIGS. 6 and 7 show an example in which a concrete plate is used as the base 30, and the other points are the same as those in the above-described embodiment. The same applies to a case where a glulam is used for the base 30 instead of the concrete plate.

[0019]

According to the present invention, by installing the laminated rubber material between the base component and the base, the shock to the building at the time of the earthquake is reduced by utilizing the high cushioning performance of the rubber. A strong and highly durable building can be provided.

Further, according to the present invention, since the laminated rubber material is provided between the base component and the base, the ventilation component can be provided between the base component and the base without processing the base component. As a result of the space being secured, the yield strength and ventilation efficiency of the base components are improved. Furthermore, since the foundation work is simplified and the installation of a ventilation port is not required, the effects of shortening the construction period and cost can be achieved.
