Description

Technical Field

[0001] The utility model belongs to the field of coupling beam dampers, and particularly relates to a corrugated steel plate coupling beam damper. Background Art

[0002] With the rapid development of China's construction industry, the building density in cities has increased and the number of building floors has risen. Traditional seismic structures are difficult to meet the usage requirements of modern buildings. In order to meet the needs of structural lateral deformation, the reinforced concrete shear wall structure undoubtedly becomes the preferred structural form. As the main energy-consuming component connecting two wall limbs, the coupling beam plays a very important role and is the first line of defense in the shear wall system. Under the action of an earthquake, the coupling beam yields and undergoes plastic deformation prior to the wall limb to dissipate seismic energy, thereby playing a role in protecting the wall limb. Due to the relatively large span-to-depth ratio in actual projects, its failure mode is mainly brittle shear failure.

[0003] Currently, the Chinese utility model with the publication number: CN 218438556 U discloses a corrugated steel plate coupling beam damper, which includes: a first end plate, a second end plate, a corrugated steel plate, a first cover plate and a second cover plate. The first end plate and the second end plate are arranged oppositely; the corrugated steel plate is fixedly connected and arranged between the first end plate and the second end plate; the first cover plate and the second cover plate are arranged oppositely, the first cover plate is fixedly connected and arranged at the bottom of the corrugated steel plate, and the second cover plate is fixedly connected and arranged at the top of the corrugated steel plate. According to the corrugated steel plate coupling beam damper of the embodiment of the utility model, aiming at the problem that general metal shear dampers are prone to local buckling, anti-buckling is achieved by improving the shape structure of the metal material at the core part of the device. Using a corrugated steel plate instead of a general planar metal structure can significantly improve the shear yield characteristics of the coupling beam. The coupling beam damper has a small volume and can be flexibly arranged without affecting the building's usage function. The damper is easy to install, and is easy to replace and repair after being damaged.

[0004] During the use of this coupling beam damper, when a single corrugated steel plate is damaged during use, it is not convenient to replace it alone. At the same time, during the use of this coupling beam damper, the waveforms of the corrugated steel plates are unified and each independently copes with the shear force, resulting in a general anti-buckling effect. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a corrugated steel plate coupling beam damper, the advantages of which are that by being placed staggeredly with each other, they can buffer and resist each other when buckling occurs, realizing anti-buckling of the oscillating force, and can be replaced separately, achieving a relatively low replacement cost.

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: A corrugated steel plate coupling beam damper includes connecting plates. The number of the connecting plates is two. Between the two connecting plates, a first corrugated plate, a second corrugated plate, and a third corrugated plate are successively arranged. At both ends of the first corrugated plate, the second corrugated plate, and the third corrugated plate, a first mounting plate is fixedly installed. On one side of the connecting plate, a first bolt is provided that penetrates through the connecting plate to the other side of the first mounting plate. On both sides of the first corrugated plate, the second corrugated plate, and the third corrugated plate, side plates are provided. At both ends of the side plates, a second mounting plate is fixedly installed.

[0007] Adopting the above technical solutions: When using the corrugated steel plate coupling beam damper, the connecting plate is connected to the external wall. When the external wall vibrates, the corrugated structures of the first corrugated plate, the second corrugated plate, and the third corrugated plate achieve anti-buckling of the oscillating force. At the same time, the first corrugated plate, the second corrugated plate, and the third corrugated plate are arranged in a staggered manner. When buckling occurs, they can buffer and resist each other, further improving the shear performance of the damper. At the same time, in the use of the corrugated steel plate coupling beam damper, when it is necessary to replace the first corrugated plate, the second corrugated plate, or the third corrugated plate, first separate the side plate from the connecting plate through the second bolt, and then disassemble between the first mounting plate and the connecting plate by removing the first bolt, so as to realize the disassembly and replacement of the first corrugated plate, the second corrugated plate, or the third corrugated plate. When the first corrugated plate, the second corrugated plate, or the third corrugated plate needs to be replaced separately, a relatively low replacement cost can be achieved, bringing convenience to the construction industry.

[0008] The present utility model is further configured such that the corrugated protrusions between the first corrugated plate, the second corrugated plate, and the third corrugated plate are arranged in a staggered manner.

[0009] Adopting the above technical solutions: Through the staggering of the first corrugated plate, the second corrugated plate, and the third corrugated plate, the shear force of the damper is increased.

[0010] The present utility model is further configured such that the first corrugated plate and the third corrugated plate have the same shape.

[0011] Adopting the above technical solutions: Since the corrugations of the first corrugated plate and the third corrugated plate are the same, they are used in a staggered manner in cooperation with the second corrugated plate.

[0012] The present utility model is further configured such that mounting holes are formed inside both the first mounting plate and the connecting plate.

[0013] Adopting the above technical solutions: Through the cooperation of the mounting holes with the first mounting plate and the first bolt.

[0014] The present utility model is further configured such that a second bolt is provided on one side of the connecting plate that penetrates through the connecting plate to the other side of the second mounting plate.

[0015] Adopting the above technical solutions: Through the cooperation of the second bolt for fastening installation between the second mounting plate and the connecting plate.

[0016] The utility model is further configured such that mounting holes II are respectively formed inside the connecting plate and the second mounting plate.

[0017] With the above technical solution: by the cooperation of the mounting holes II, the second mounting plate and the second bolt.

[0018] The utility model is further configured such that the first mounting hole and the second mounting hole are respectively penetrated and mounted by the first bolt and the second bolt.

[0019] With the above technical solution: by the connection and installation of the first mounting hole and the second mounting hole with the first mounting plate and the second mounting plate respectively.

[0020] The utility model is further configured such that a third mounting hole is formed inside the connecting plate.

[0021] With the above technical solution: the connecting plate is firmly mounted to an external building wall through the cooperation of the third mounting hole and an external bolt.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. When the corrugated steel plate coupling damper of the utility model is in use, the connecting plate is connected to the external wall. When the external wall vibrates, the corrugated structures of the first corrugated plate, the second corrugated plate and the third corrugated plate achieve anti-buckling of the oscillating force. At the same time, the first corrugated plate, the second corrugated plate and the third corrugated plate are arranged in a staggered manner. When buckling occurs, they can buffer and resist each other, further improving the shear performance of the damper;

[0024] 2.
