Abstract

PROBLEM TO BE SOLVED: To prevent a disaster such as collapse by protecting a detached house from the lateral quakes of a severe earthquake. SOLUTION: Sliding layers 5 isolating foundations from a ground and sliding the foundations together with a building by inertia to the large lateral quakes of a large-scale earthquake are interposed among the ground and the foundations 3, 4 bearing the building.

The crushed stone is crushed and ground on the ground to have an area larger than the flat area of the foundations 3 and 4, and the crushed soil is constructed. When this leveling layer has hardened, a sliding layer 5 is provided thereon, and then a solid foundation 3 or a cloth foundation 4 is constructed of concrete on the sliding layer 5 insulated from the leveling layer 2 by the sliding layer.

FIG. 1 shows a case where a waterproof PVC sheet is used as the sliding layer 5. If a PVC sheet is laid on the leveling layer as a sliding layer and the foundation 3 or 4 is constructed of concrete, the foundation is insulated from the leveling layer 2 by the PVC sheet and does not bond with the leveling layer. And the layer 2
The area of is larger than the areas of foundations 3 and 4, so if you fix the base on the foundation and build a building on it,
Regardless of the direction in which the initial instantaneous large sway of a large earthquake strikes from any direction, the foundation is integrated with the building and the sliding layer 5 with inertia and in the horizontal direction relatively opposite to the sway and on the layer 2 It can prevent slippage and collapse. If a small earthquake shakes, the foundation, the building and the sliding layer move in synchronization with the shake, but no major disaster occurs.

The case where a waterproof PVC sheet is used as the sliding layer 5 has been described in the embodiment of FIG. 1, but as shown in FIG. 2, pebbles, sand, gravel, glass beads, A granular material such as a steel ball is spread in a layer having a thickness of, for example, about 50 mm, and an insulating sheet 7 such as a PVC sheet, waterproof paper, oil paper, or felt sheet is laid thereon, and a sliding layer is formed by the granular material layer 6 and the insulating sheet 7. 5 and the foundations 3, 4 may be built thereon. Further, as the sliding layer, styrofoam having a thickness of about 50 to 200 mm or a heat insulating board made of urethane can be used, and using such a heat insulating board also has an effect of heat insulation from under the floor.

As is apparent from the above description, according to the present invention, the foundation 3 or 4 is insulated from the ground work 1 provided integrally with the ground and the leveling layer 2 thereon by the sliding layer 5. Since the building is built on concrete and the building is built on the foundation, if there is a large amount of instantaneous extreme sway in the early stage of a large earthquake, the foundation will be inertial with the building above it and the direction opposite to the earthquake sway Moves relatively to. Therefore, it is possible to prevent the collapse of the building itself due to the strong horizontal shock of the large earthquake and the fall and fall of the interior furniture and furniture in the building beforehand.
