Description

TECHNICAL FIELD The present application relates to a seismic resistant device for buildings.

[Prior Art] The seismic intensity of an earthquake can be distinguished from a strong earthquake, a strong earthquake, and a severe earthquake.
Buildings such as current wooden houses to reinforced concrete buildings are fixed to the ground with basic concrete.

[Problems to be Solved by the Invention] The conventional techniques described above have the following problems.

When a fixed building receives a severe earthquake, the building collapses and many lives are lost.

In other words, the structure of the present building that the shape of the building does not remain even if you watch the video of the Soviet earthquake and the Great Kanto Earthquake in Japan, the building of wooden reinforced concrete etc. If you can freely bend in either direction,
Collapse of the building can be avoided, but then the building materials of the house will be damaged and you will not be able to live inside.

Even if the building does not collapse due to the "scenery", it is inevitable to collapse furniture. There is also the possibility of personal injury or loss of life.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

This application does not fix the building to the ground, foundation concrete.

The ground, foundation concrete and lower frame are fixed with anchor bolts.

The same applies to heavy buildings in which buildings, columns, studs, outer walls, streaks, etc. are fixed to the upper frame.

On the lower surface of the upper frame and the upper surface of the lower frame, surface plates made of steel with a surface planar finish are attached vertically, and oil is added to improve sliding.

A coil spring is stretched between the upper frame and the lower frame such that the center of the lower frame is aligned with the center of the upper frame.

The strength of the coil spring is determined in consideration of the maximum seismic intensity and the weight of the building.

[Operation] Even if there is a sway in any direction such as front, back, left, right, or diagonal, only the ground and the lower frame sway, and the upper frame and the building do not sway.

Embodiments of the Invention Embodiments will be described with reference to the drawings.

 Reference numeral 1 is a building seismic resistant device of the present invention.

2 is the lower frame, front and rear materials 2A, 2B and left and right materials 2
It is composed of a frame body 2E in which C and 2D are connected in a plane rectangular shape.
The vertical and horizontal reinforcements 2F are stretched inside 2E.

Reference numeral 3 denotes an upper frame which is arranged on the upper surface of the lower frame 2 in a laminated state, and is constituted by a frame body 3E in which front and rear materials 3A and 3B and left and right materials 3C and 3D are connected to each other in a planar rectangular shape. Inside, there are 3F horizontal and vertical reinforcements.

In the illustrated case, the lower frame 2 and the upper frame 3 are configured to have the same shape when seen from a plane, but needless to say, they do not have to have the same shape.

The frames are made of wood, metal material, synthetic resin material, or the like.

Reference numeral 4 is a coil spring stretched between the lower frame 2 and the upper frame 3.

Therefore, the tension state of the coil spring 4 is as follows.

On the upper surface of the lower frame 2, in the upper frame 3 arranged in a stacked state, a coil spring 4 is stretched between the lower frame 2 and the upper frame 3, and by the action of the coil spring 4, the plane of the lower frame 2 is changed. The center viewed from the plane of the upper frame 3 is configured to coincide with the viewed center.

In this case, the strength of the coil spring 4 is determined in consideration of the maximum seismic intensity, the building weight, and the like.

Furthermore, the seismic intensity at the time of mounting the coil spring 4 and the tensile strength suitable for the weight of the building are measured with a measuring instrument.

The mounting state of the coil spring will be described in detail with reference to FIGS. 4 and 5.

 FIG. 4 is a bottom view of the upper frame 3.

An appropriate number of coil springs 4 are connected to the inner wall of the upper frame 3 at predetermined intervals at outer ends 4A. (The drawing shows the case where there are 20 coil springs.) FIG. 5 is a plan view of the lower frame 2.

The inner end 4B of the coil spring 4 is connected to the side walls of the vertical and horizontal reinforcing members 2F in the lower frame 2. (In the figure, there are 20 coil springs.) In this case, the connection point of the inner end 4B of the coil spring 4 is at the position where the coil spring 4 acts on the center of the lower frame 2.

5 is a surface plate made of steel with a surface planar finish, and is a lower surface plate 5A attached to a predetermined location on the upper surface of the lower frame 2.
And an upper surface plate 5B attached to a predetermined portion of the lower surface of the upper frame 3 so as to correspond to the lower surface plate 5A.

In this case, grooves 5A1 for lubricating oil are engraved in a plane radial pattern on the upper surface of the lower surface plate 5A.

An oil supply pipe 5B1 for lubricating oil is connected to the center of the upper surface plate 5B.

And, an oil supply tank (not shown) is provided in this oil supply pipe 5B1.
Are connected.

In the figure, 6 is a building, 6A is a concrete base, 6B is basic concrete, 6C is an anchor, 6D is a pillar, and 6E is an outer wall.

[Effects of the Invention] Since the present invention is configured as described above, it has the effects described below.

With this device, even an earthquake with seismic intensity of 7 to 8 can transmit only 1/10 of the seismic intensity to a building.

Therefore, it is possible to prevent the furniture and fittings from collapsing and the tableware from being damaged.

Buildings with this seismic device are safe for human life in buildings, supermarkets, and other places where many people gather, and also for these buildings.

This seismic device is a device that can withstand severe earthquakes from any direction, such as vertical, horizontal, and diagonal.
