Description

  The present invention relates to a damping structure in which a damping member is provided between a housing and a face material, and a damping panel and a damping member used therefor.

  One method of reducing earthquake damage by improving the earthquake resistance of a house or building is to install a damper that absorbs energy during the earthquake in the structural frame of the building to reduce the vibration of the building. In large buildings such as buildings, hydraulic dampers and steel dampers are generally used, but these dampers are large and require considerable speed and force to deform. Therefore, it is difficult to apply to small buildings such as houses.

  Therefore, as a vibration control structure applicable to a small building such as a house, Patent Document 1 discloses that a pillar formed of a combination of a wire such as a pillar, an inter-column, and a beam and a face material such as a fireproof board. In addition, it is disclosed that these are fixed in a state in which a viscoelastic body is interposed on a joint surface formed between the stud and the fireproof board. And according to this, it is described that it is possible to exhibit excellent vibration control performance even when it is constructed with a material having a large deformation capability.

However, in the vibration control structure disclosed in Patent Document 1, a face material such as a fireproof board is directly fixed to a frame of a wire material such as a pillar, a stud, and a beam, though a viscoelastic body is interposed. Therefore, there is concern about the risk of unevenness and undulations. In addition, this structure is intended to exhibit excellent vibration control performance by deformation of the viscoelastic body in a detached house made of wood or steel frame with small elastic rigidity and large deformation capacity. Since the elastic body has a play of about 1 mm, there is a problem that energy absorption due to deformation of the viscoelastic body cannot be expected for a small earthquake.
