Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration damper device. Specifically, when a layer displacement force due to wind pressure or an earthquake acts on a building or other structure, the displacement (vibration) energy is absorbed and the shaking motion or vibration of the structure is dampened. The present invention relates to a vibration damper device that is used by being incorporated as a brace, a cane or the like in the structural frame.

[0002]

2. Description of the Related Art In general, a vibration damper device of this type is provided between a plurality of first rigid members such as steel plates which are arranged in parallel with each other at intervals and adjacent members of the plurality of first rigid members. An energy absorbing material such as a viscoelastic body is interposed in layers between the facing surfaces of the at least one second rigid member such as a steel plate and the like which are arranged in parallel to the first rigid member at the intermediate position. Due to the interlayer displacement force acting on the structural frame, the first rigid member and the second rigid member form a two-dimensional surface (plane).
When the relative displacement in the inside, the displacement energy is absorbed by the shear deformation of the layered energy absorbing material,
It is configured to exhibit damping performance that damps the shaking and vibration of a building.

By the way, in the vibration damper device which exerts the vibration damping performance by utilizing the shear deformation characteristic of the energy absorbing material as described above, generally, in order to confirm the quality of the product (damper device) before the product is shipped. , Giving a test displacement force assumed to occur due to an earthquake, etc., and confirming and verifying the relative displacement amount and displacement operation status of the first rigid member and the second rigid member with respect to this test displacement force. Performance testing is important. In addition, in the actual use condition where the tamper device is installed in the structural frame of a building, the inter-layer displacement force due to an earthquake etc. acts to judge the degree of deterioration of vibration damping performance and durability such as continuous use. It is a very important matter to confirm and verify the relative amount of displacement between the first rigid member and the second rigid member, the displacement operation state, etc.

In order to confirm quality confirmation and performance durability, which are important matters for such a vibration damper device, conventionally, the first rigid member and the second rigid member are provided in the damper device.
An electric displacement sensor that can detect the relative displacement amount and displacement operation status with the rigid member is installed, and the displacement detection signal from this sensor is extracted and recorded, or the relative displacement amount and displacement operation status are displayed on the screen. Means for confirming and verifying are known.

[0005]

However, in the case where the electric displacement sensor is incorporated in the damper device as described above, in addition to the sensor main body, ancillary equipment such as a signal line, a displacement recording device or a display device is required. From that,
Not only a large initial investment is required, but also a great deal of labor and cost are required for maintenance such as checking whether the sensor is kept in a normal operating state or checking the power consumption of the power supply battery. In addition, even if there is no problem in the performance test before shipping that can secure the power supply, the displacement sensor is normal due to disconnection of the lifeline (commercial power supply) or power supply battery when an extremely low frequency earthquake occurs in actual use. There is a problem in that it may not work, and there is a possibility that it will be impossible to confirm and verify the performance durability of the device at the most desired time.

The present invention has been made in view of the above-mentioned circumstances, and the initial investment is small and maintenance is not required, but the standard of quality confirmation at the time of performance test before product shipment and the actual use state are required. It is an object of the present invention to provide a vibration damper device that can accurately determine the performance durability of the.

[0007]

In order to achieve the above object, a vibration damping device according to the present invention is provided with a first rigid member and a second rigid member arranged in parallel with the first rigid member.

According to the present invention having the above-described structure, the relative displacement in the two-dimensional plane is obtained both during the performance test performed before the product is shipped and when the interlayer displacement force is applied due to the occurrence of an earthquake or the like in the actual use state. By recording the relative displacement history between the displacing first rigid member and second rigid member with a physical displacement history recording means, the entire device can be compared with the case where an electrical displacement sensor that requires initial investment and maintenance is incorporated. While it is possible to reduce the cost and maintenance-free, it is possible to use it as a standard for judging the performance test result of the shipped product, that is, the quality confirmation from the physical record displacement history, and it is also possible to use it as an earthquake in the actual use condition. It is possible to confirm and verify the relative displacement amount and the displacement operation status, etc., and always judge the performance durability and the like.

In particular, as a displacement recording means in the vibration damper device having the above-mentioned structure, as described in claim 3, a needle-shaped writing member made of a hard material attached to one of the first and second rigid members which are relatively displaced. , For example, by using a scribing needle or an iron brush and the like, and a plate-shaped writing member attached to the other corresponding to this needle-shaped writing member, such as a scribing plate or a file plate and a base paper, Even when an interlayer displacement force is applied due to an earthquake, which is extremely rare in actual use, the displacement history is greater than that of an electric displacement sensor and handwritten recording using consumable materials such as ink. It is possible to accurately record (mark off) without losing the performance, and to accurately judge the performance durability and the like of the damper device.

Further, as the displacement history recording means, a needle-shaped writing member made of a hard material such as a scribing needle or an iron brush and a plate-shaped writing member such as a scribing plate or a file plate and a base paper are used. As described above, at least one of the needle-shaped writing member and the plate-shaped writing member, and the first and second
By adopting a structure in which an elastic body that elastically maintains the contact state between the tip of the needle-shaped writing member and the writing surface of the plate-shaped writing member is interposed between at least one of the rigid members, the vibration damping damper device. When the first rigid member and the second rigid member constituting the above are relatively displaced in a two-dimensional plane in the main direction, even if a displacement force in a direction intersecting the relative displacement surface acts, the displacement force is The tip of the needle-shaped writing member and the writing surface of the plate-shaped writing member are kept in contact with each other with a substantially constant pressure by being absorbed by an elastic body, without causing damage to the writing member or occurrence of recording error, etc. The displacement history can be reliably recorded.

As the energy absorbing material in the vibration damper device according to the present invention, an elastic body such as urethane asphalt rubber or a high damping rubber may be used in addition to the viscoelastic body and the thermoplastic elastomer.
