Description

  The present invention relates to a damper set introduced into a structure.

  Conventionally, a damping mechanism disclosed in Patent Document 1 has been proposed for the purpose of efficiently absorbing large vibration energy such as a large earthquake and preventing damage to structural members of a building.

  The vibration control mechanism disclosed in Patent Document 1 is configured by connecting the friction members via a friction damper so that the bent members of the pair of frame members have a substantially X shape. The upper and lower connecting plates are fixed to the base and the beam, and the direct material is fixed to the column. Thereby, the seismic control mechanism disclosed in Patent Document 1 absorbs the vibration energy by the friction damper when a large earthquake or the like occurs, and prevents the column from being pulled out or pulled in.

JP 2001-336303 A

  However, the vibration control mechanism disclosed in Patent Document 1 uses a pair of bent member frame members, and uses the frictional resistance of the friction damper by the pressing force acting on the pair of frame members. For this reason, when the pressing force acting on the pair of frame members becomes insufficient, there is a problem that vibration energy cannot be sufficiently absorbed and the building may collapse.

  Moreover, since the seismic control mechanism disclosed in Patent Document 1 uses a pressing force acting on a frame member of a pair of bent members, it is applied when a brace member is not provided in a building. There was a problem that the building could not be able to be absorbed, vibration energy due to a large earthquake or the like could not be sufficiently absorbed, and the building could collapse.

  Furthermore, the vibration control mechanism disclosed in Patent Document 1 is applied only to the position where the brace material is provided, even when the brace material is provided in the building. There was a problem that energy could not be absorbed sufficiently and the building could collapse.

  Accordingly, the present invention has been devised in view of the above-described problems, and the object of the present invention is to make vibrations acting on the structure corresponding to the magnitude of vibrations acting on the structure. An object of the present invention is to provide a damper set capable of absorbing in stages according to displacement.

  A damper set according to a first aspect of the present invention is a damper set that is introduced into a structure, and includes a first member provided with a first attenuation portion and a second member provided with a second attenuation portion. Either one or both of the member and the second member is fixed to a part of the structure, and the first damping unit and the second damping unit respond to the displacement of the vibration acting on the structure. It is characterized by being attenuated step by step.

  The damper set according to a second invention is the damper according to the first invention, wherein either one or both of the first member and the second member is one or both of the first attenuation portion and the second attenuation portion. The first member or the second member is perturbed while forming a metal flow site inside the friction plane without forming an interface in a different material contact state with the friction plane having improved smoothness. Thus, the vibration acting on the structure is attenuated stepwise according to the displacement.

  A damper set according to a third invention is the damper set according to the first or second invention, wherein either the first member or the second member is attached to a wall frame of a structure, and the first member and the second member One of the two members is attached to a face material of the structure.

  The damper set according to a fourth aspect of the present invention is characterized in that, in the first aspect or the second aspect, the first member and the second member are attached to a brace provided to be inclined on a wall frame of a structure.

  The damper set according to a fifth aspect of the present invention is characterized in that, in any one of the first to fourth aspects, the first attenuation portion and the second attenuation portion are provided so as to overlap each other in an out-of-plane direction.

  The damper set according to a sixth aspect of the present invention is characterized in that, in any one of the first to fifth aspects, the first attenuation portion and the second attenuation portion are provided with their positions shifted in the in-plane direction. .

  In the damper set according to a seventh aspect of the present invention, in the sixth aspect of the invention, either one of the first member and the second member is provided on the side of the protrusion and a protrusion provided to protrude in an in-plane direction. When the vibration acting on the structure is attenuated by deforming the protruding portion, the protruding portion is brought into contact with the auxiliary portion to maintain the predetermined vibration damping performance. The abutting surface that abuts the projecting portion and the auxiliary portion is curved so that it can be deformed in such a state.

  According to 1st invention-7th invention, when a small vibration acts on a structure, either one of a 1st attenuation | damping part and a 2nd attenuation | damping part swings in the range of a small long hole, and a structure When a large vibration is applied to the structure, either the first damping part or the second damping part swings in the range of the large and long hole, so it can efficiently cope with the magnitude of the vibration acting on the structure. Thus, vibrations acting on the structure can be absorbed stepwise according to the displacement.

  In particular, according to the second invention, when the first member and the second member are oscillated, the metal member is oscillated without forming an interface, while forming a portion where the metal flows inside the friction plane. A significantly higher coefficient of friction can be obtained compared to the frictional resistance that forms the interface. At this time, according to the second invention, it is possible to remarkably improve the absorption performance with respect to vibrations acting on the structure, and to reliably prevent the structure from collapsing and the face material from collapsing.
