Description

[Detailed description of the invention] [Industrial application field] This invention relates to a building restraint device.

[Prior art and problems to be solved by the invention] Generally 2
．． When a building vibrates due to an earthquake or wind, it generates vibrational energy, and if this vibrational energy is large enough, the building may collapse.

Traditionally, buildings have been designed to resist this type of vibrational energy solely through their strength. but,
This would require the cross sections of the columns and beams to be considerably large, which is not a good idea from both a functional and economic point of view.

For this reason, recently, earthquake-resistant construction methods have been proposed that can absorb the vibration energy caused by earthquakes and wind through deformation, and seismic isolation methods that prevent the transmission of seismic force to buildings as much as possible.

However, both construction methods are structurally complex and often have poor functionality.

This invention was proposed in view of the above circumstances, and is a building that has an extremely large damping capacity and can quickly absorb the vibration energy caused by vibrations of the building caused by earthquakes and wind, thereby preventing the building from being destroyed. The purpose is to provide a restraining device.

Means for Solving Problem C] This invention involves inserting a resistance plate between spaces filled with high viscosity fluid, supporting one part of the plate with a pin, and using one end of the resistance plate to absorb the vibrations of the building. The purpose is achieved by installing the resistor plate so as to dampen the vibrations of the building by absorbing the resistance of the high viscosity fluid while amplifying the vibrations of the building with most of the resistance plates.

〔Example〕

Hereinafter, the present invention will be explained with reference to an illustrated embodiment.

In Figures 1, 2 and 3, reinforced concrete
1. Three first resistance plates 3゜3 are erected in equilibrium and at regular intervals within the frame composed of structural columns 1.1 and beams 2, 2, and the lower end and both left and right ends The section is completely sealed.

A highly viscous fluid 4 such as a hydrocarbon-based fluid material of approximately 60,000 poise is filled between the first resistance plates 3.3.

Two fan-shaped second resistance plates 5.5 are built into the highly viscous fluid 4 between the first resistance plates 3.3.

The second resistance plates 5, 5 have a slightly upper part than the center part of the second resistance plates 5, 5.
The resistance plate 3.3 is rotatably supported by a pin 6 at the two ends of the resistor plate 3.3, and its -L-M1 section is rotatably connected directly to the center of the beam 2 on the second floor by a pin 7. has been done. In addition, the first resistance plates 3, 3 and the second resistance plates 5, 5
Exterior panels 13.13 are attached to both sides of the wall, and the first resistance plate 3.3 and the second resistance plate 5.5 are embedded in the wall. In such a configuration, when the building vibrates due to earthquake force or wind, the vibration coherence (relative velocity generated between the layers) is transmitted to the end of the second resistor plate 5. It is amplified by the vibration centered on the pin 6 of the plates 5,5.

The amplified relative speed difference between the second resistive plates 5, 5 and the first resistive plate 3.3 generates a shearing resistance force due to the gap of the high viscosity fluid present between the drawing plates.

As a result, the vibration energy generated when the building vibrates due to earthquakes or wind is quickly attenuated.

This damping force can be adjusted by the number and area of the first and second resistance plates 3 and 5 and the installation interval of the first and second resistance plates 3.5.

Therefore, it can be expressed as Here, the area d of the resistance plate A is
v is the relative velocity, dy is the gap between the resistance plates, and α is a coefficient determined by experiment.

4 to 6 show a second embodiment of the present invention, in which the second resistance plate 5 is formed in the shape of a vertically long strip. The resistor plates 5 are built in the high viscosity fluid 4 between the first resistor plates 3°3 at regular intervals in the width direction of the second resistor plate 5, and the plate portion slightly from the center is the first resistor plate. 3, 3 is rotatably supported by a pin 6 at the upper end of the
The two ends are rotatably supported by a pin 7 directly at the center of the beam 2 on the first floor. In addition, the second resistance plate 5...
The lower end portions of ... are connected by a connection Fj, 8.

In such a configuration, its function is exactly the same as in the first embodiment.

Furthermore, FIG. 7 shows a third embodiment of the present invention, in which a swinging plate 9 is rotatably connected at its plate portion slightly from the center to an amplifying pin support plate 14 by a pin 10. The upper end is straight and is rotatably connected to the center of the beam 2 on the second floor by a pin 11, and the lower end of the moving plate 9 is equipped with a fluid damper 1 using a high viscosity fluid.
2.12 is installed.

In this configuration, the vibration energy of the building due to earthquakes and wind is amplified in the portion of the rocking plate 9 below the pin 10, and is attenuated by the action of the fluid damper 12.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects.

■ The vibration energy of buildings caused by earthquakes and wind is first amplified and then damped by the viscous shear resistance of highly viscous fluid, so the damping force is extremely high.

Therefore, in order to exert the same level of damping force, it is necessary to use a smaller scale than the conventional one.

■ The damping force can be adjusted over a wider range depending on the size of the resistance plate, the number of particles, and the high viscosity ('l material), so it is possible to adjust the optimal damping force according to the scale of the building. Cowness - 1 can be done.

■ Since the damping force is extremely large, it goes without saying that it can be used alone, and can also be used as a damping device for seismic isolation construction methods.

Furthermore, it can be used not only for buildings but also as a damping device for equipment, equipment, workpieces, etc., and is extremely versatile and highly practical.

■ Compared to buildings designed using the 1π earthquake-resistant design method, installation is much more economical.

■ Since the entire device is installed inside the wall of the building, it is easy to install and is extremely easy to install.
