[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house building and the like, and more particularly, to an electric protection device for a house building which automatically prevents a base of a house from vibrating due to an earthquake or the like.

[0002]

2. Description of the Related Art Various methods and devices have been developed for seismic resistance of a residential building due to an earthquake or the like. Nothing could be attached to the base.

[0003]

In order to solve such a conventional method, there is a problem to be solved by the present invention. That is, there is a problem to be solved by the present invention in that vibration energy generated at the time of an earthquake is absorbed between a base part and a base part of a building such as a house to prevent collapse of the house building.

[0004]

SUMMARY OF THE INVENTION The present invention has been developed to solve the above-mentioned problems, and comprises a block base 1 having a mortar-shaped hole 2 on which a steel ball 3 is placed, and a mortar-shaped lid. In the anti-vibration device including the base fitting member 4 having the portion 5, the pot-shaped hole portion 2, the pot-shaped lid portion 5, and the center of the inner surface of the block base 1 and the base fitting material 4 are provided. The hole 6 is formed in the same shape, and the pressure-resistant elastic member 7 having the depression assisting pin 11 is overlapped on the outer surface of the base fitting member 4 so that the base support plate 9
The steel ball 3 in the normal state is a mortar-shaped hole 2 of the block base 1 and a mortar-shaped lid 5 of the base fitting 4.
However, when the stress caused by the vibration is applied when an earthquake occurs, the steel ball 3 is swung, and the block base 1 and the base fitting 4 are located in a narrow space opposite to each other. The base fitting 4 is pressurized by the steel ball 3 via the pressure-resistant elastic member 7 in a swinging state such as front and rear, left and right, and up and down, thereby causing load and vibration. A vibration preventing device for a residential building, characterized in that energy is absorbed by the steel balls 3 and the pressure-resistant bullets 7.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention comprises a block base 1 having a mortar-shaped hole 2 on which a steel ball 3 is placed, and a base fitting 4 having a mortar-shaped lid 5. In the anti-vibration device, the block base 1 and the base fitting 4
The pot-shaped hole 2, the pot-shaped lid 5, and the central hole 6 on the inner surface of the base member are formed in the same shape, and the pressure-reducing aid pin 11 is provided on the outer surface of the base fitting 4. The base support plate 9 is fixed by stacking the elastic bullets 7, and the steel ball 3 in the normal state is the center of the mortar-shaped hole 2 of the block base 1 and the mortar-shaped lid 5 of the base fitting 4. When the stress caused by the vibration is applied during the occurrence of an earthquake, the steel ball 3 is swung, and the block base 1 and the base fitting 4 push open the narrow space at the opposite position. The base fitting 4 is pressurized by the rocking of the steel ball 3 via the pressure-resistant elastic material 7 in a swinging state such as front and rear, left and right, and up and down, so that the load and vibration energy are reduced. Since it is an anti-vibration device for a residential building, which is absorbed by the steel ball 3 and the pressure-resistant bullet 7, the base fitting material is provided via the steel ball 3. There is rotated pivotally, yet can be returned to automatic return position building if stationary vibration with able to automatically absorbed via the steel balls 3 an electric energy generated during an earthquake.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a vibration preventing device for a residential building according to the present invention, and FIG. 1 shows a state where the device is buried between a foundation A and a base B. is there.

First, a vibration preventing device according to the present invention is shown in FIG.
As shown in the figure, a block base 1 having a mortar-shaped hole 2 for mounting a steel ball 3, a base fitting 4 having a mortar-shaped lid 5, a pressure-resistant bullet 7 having a center hole 8, and a center And a base support plate 9 having a pressure sinking assisting pin 11.
Next, a steel ball 3 is swingably inserted between the mortar-shaped hole 2 of the block base 1 and the mortar-shaped lid 5 of the base fitting 4 and the base fitting 4 Layer of pressure-resistant ammunition 7 on top of
Further, if the pressure-resistant bullet 7 is fixed to the base support plate 9 with the depression assisting pin 11, the device can be embedded between the foundation A and the base B as shown in FIG. In the figure, reference numeral 6 denotes a central portion of the lid of the mortar-shaped lid portion 5, and reference numeral 10 denotes a fixing bin hole of the base support plate 9.

FIG. 3 shows an operation state of the vibration preventing device for a residential building according to the present invention. First, as shown in FIG. 1, the anti-vibration device in a normal state has a steel ball 3 installed in the center of a mortar-shaped hole 2 of a block base 1 and a mortar-shaped lid 5 of a base fitting 4. Have been. Next, when an earthquake occurs, as shown in FIG. 2, when the stress due to the vibration is applied in the direction of the arrow, the steel ball 3 is swung, and the block base 1 and the base fitting 4 are positioned at opposite positions. It swings (or moves) while pushing open a narrow space. This steel ball 3
Swings the base fitting 4 via the pressure-resistant elastic member 7 so as to freely swing back and forth, left and right, up and down, and the like. As a result, the load or vibration energy applied from above, below, left, and right is absorbed by the steel ball 3 and the pressure-resistant bullet 7.

[0010]

The present invention relates to an anti-vibration device comprising a block base 1 having a mortar-shaped hole 2 on which a steel ball 3 is placed and a base fitting 4 having a mortar-shaped lid 5. The pot-shaped hole 2, the pot-shaped lid 5, and the central hole 6 on the inner surface of the block base 1 and the base fitting 4 are formed in the same shape. The sinking assist pin 11 on the outer surface
The base support plate 9 is fixed by stacking the pressure-resistant bullets 7 having the above. The steel ball 3 in the normal state has the mortar-shaped hole 2 of the block base 1 and the mortar-shaped lid 5 of the base fitting 4. The steel ball 3 is oscillated when the stress caused by the vibration is applied when an earthquake occurs.
The base fitting 4 is swung while pushing and opening the narrow space at the opposite position, and the base fitting 4 is moved back and forth, right and left, and up and down through the pressure-resistant elastic material 7 by the swing of the steel ball 3. The vibration preventing device for a residential building is characterized in that the load and the vibration energy are absorbed by the steel balls 3 and the pressure-resistant ammunition 7 while being pressurized in a freely oscillating state. Has many effects. A. Since this device can be realized by simply combining simple members, it can be easily and easily buried in the foundation and base of a building such as a house, and can be manufactured at low cost and in mass production. B. Since the block base in which the steel balls are mounted and the base fitting are formed in a mortar shape, it is possible to repel even if the seismic force is applied from any direction due to an earthquake or the like. . C) When the seismic force is pressurized from above and below, the steel ball that supports the load pushes up the mortar-shaped gradient and swings (moves) while absorbing the seismic force. ) Is also pushed up from below, so it can absorb vibration energy. D. When the quake stops, the steel ball is in a mortar shape, so the building is automatically returned (the position of the steel ball).
Can be returned to.
