Abstract

PURPOSE: To provide an earthquake resistant foundation construction for protecting a building from both rolling and pitching (vertical type) of an earthquake. CONSTITUTION: Burying holes 3 are bored in the horizontal concrete foundation 2 laid in area larger than a floor space at specific intervals, and a shock absorber 1 consisting of a horizontally fixed bottom slab 5, a crushing ball 6 enclosed with liquid 7 in the inside cavity thereof mounted on the horizontally fixed bottom slab 5 and a shape type oscillating plate 8 rolling the crushing ball 6 on the horizontally fixed bottom slab 5 is buried between an inside bottom 3a of each of the burying holes 3 and a floor surface 4 of a building B with the horizontally fixed bottom slab 5 and shade type oscillating plate 8 respectively fixed to the horizontal concrete foundation 2 and the floor surface 4 of the building B. Shock caused by pitching is absorbed in allowable range of oscillation in the burying holes 3, and shock caused by pitching is absorbed by deformation crushing operation of the crushing ball 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake-resistant basic structure of a building mainly for general houses as an earthquake countermeasure.

[0002]

2. Description of the Related Art Earthquake-resistant basic structures for buildings in preparation for an earthquake have been proposed so far, but mainly for general houses,
So far, no technology has been considered that takes into account simultaneous or asynchronous vibrations of horizontal shake and vertical shake (direct type), and also takes into account short-time vibrations (several seconds to ten and several seconds).

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above conventional circumstances, and it can be applied to general houses by either horizontal shake or vertical shake (directly below), either simultaneously or at different times. Protects the building from the heat, and provides a seismic foundation structure for the building that takes into account economic efficiency because it can be settled in a short time.

[0004]

In order to achieve the above object, according to the present invention, embedded holes 3 are provided at predetermined intervals in a horizontal concrete foundation 2 laid in a range wider than a building floor. And
Between the inner bottom surface 3a of each buried hole 3 and the floor surface 4 of the building B,
A horizontally fixed bottom plate 5, a collapsing ball 6 in which a liquid 7 is enclosed in an internal cavity 6a placed on the horizontally fixed bottom plate 5, and a cap for rolling the collapsing ball 6 on the horizontally fixed bottom plate 5. The impact absorbing device 1 including the mold rocking plate 8 and the horizontal fixed bottom plate 5
Are embedded in the horizontal concrete foundation 2 and the shade type rocking plate 8 on the floor surface 4 of the building B, respectively. And
The impact of lateral shake is absorbed within the permissible swing range of the buried hole 3, and the impact of vertical shake is absorbed by the deformation and crushing action of the crush ball 6 mounted on the horizontal fixed bottom plate 5. It is an earthquake-resistant foundation structure. Further, in the above structure, the crushing ball 6 is made of stainless steel, and the internal cavity 6a is filled with the oil 7 to provide a seismic basic structure of a building.

[0005]

Since the present invention is configured as described above, when a lateral shake earthquake occurs and the lateral shake of the ground and foundation is transmitted to the building B, as shown in FIG. Buried hole 3 The cap-type rocking plate 8 of the shock absorbing device 1 buried between the floor surface 4 and the buried hole 3 swings laterally in the rocking allowable range of the buried hole 3 and rolls the crush ball 6 onto the horizontal fixed bottom plate 5. Move to absorb lateral shock. Next, when a direct-type vertical vibration occurs and the vertical vibration of the ground and foundation is transmitted to building B,
As shown in FIG.
Due to the vertical impact pressure, the ball 6 is crushed via the cap-shaped oscillating plate 8 of the shock absorber 1, and its deformation crushing action (eventually the crushing ball 6 may be destroyed) causes vertical vibration. It absorbs shocks and protects the building from direct hits, even for a few seconds.

[0006]

[Example] Horizontal concrete laid in a wider area than the building floor
The embedded holes 3 are provided at predetermined intervals on the base 2. Then, between the inner bottom surface 3a of each buried hole 3 and the floor surface 4 of the building B, oil 7 is placed in a concrete horizontal fixed bottom plate 5 and an internal cavity 6a placed on the horizontal fixed bottom plate 5. A shock absorbing device 1 comprising an enclosed stainless steel crush ball 6 and a concrete cap-shaped rocking plate 8 for rolling the crush ball 6 on the horizontal fixed bottom plate 5. The horizontal fixed bottom plate 5 is attached to the horizontal concrete base 2 and the shade type swing plate 8
Are fixed and buried in the floor surface 4 of the building B, respectively. Then, the shock due to the lateral shake is absorbed within the swingable range of the buried hole 3, and the shock due to the vertical shake is absorbed by the deformation and crushing action of the crush ball 6 placed on the horizontal fixed bottom plate 5. It is a seismic foundation structure of the building.

Since the present invention is configured as described above, when a lateral shake earthquake occurs and the lateral shake of the ground and foundation is transmitted to the building B, as shown in FIG. The burial plate 8 of the shock absorber 1 embedded between the burial hole 3 and the floor surface 4 shakes laterally within the permissible oscillating range of the burial hole 3 to roll the crush ball 6 onto the horizontally fixed bottom plate 5. Absorbs lateral impact. Next, when a direct-type vertical vibration occurs and the vertical vibration of the ground and foundation is transmitted to building B,
As shown in FIG. 5, the squeezed balls 6 placed on the horizontal fixed bottom plate 5 are crushed by the vertical impact pressure via the cap-type swing plate 8 of the impact absorbing device 1, and the deformation crushing action (finally The crushed ball 6 may be destroyed) to absorb the shock caused by the vertical vibration, and protect the building from a direct hit even for a few seconds. In addition, as shown in FIG.
In the case where the side surface is formed into a spherical concave surface, due to strong wind
Prevent the building from moving in all directions.
