Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0042] In order to solve the above problems, the inventor invented a strain augmentation device, which can be applied to ordinary dampers, such as plate dampers, so that the deformation transmitted from the building is amplified by the strain augmentation device and then transmitted to Damping rubber, in order to increase the deformation of the damping rubber and improve energy consumption efficiency, the specific plan is as follows:

[0043] Such as Figure 1 to Figure 5 Shown, a kind of strain amplification device, it comprises the first connecting steel plate 1, outer interlayer steel plate 16, eccentric sector gear 2 and the second connecting steel plate 15, the first connecting steel plate 1 is two pieces, and described first connecting steel plate 1 two The upper part between the outer interlayer ste...

Abstract

The invention discloses a strain increasing device and a damper. The strain increasing device comprises a first connecting steel plate, outer sandwich steel plates, an eccentric sector gear, and a second connecting steel plate. The lower part of the first connecting steel plate is disposed in the upper part between the two outer sandwich steel plates. The eccentric sector gear is arranged between the two outer sandwich steel plates. The second connecting steel plate is arranged in the lower part between the two outer sandwich steel plates. The lower side face of the first connecting steel plate is meshed with the upper teeth of the eccentric sector gear through teeth. The energy efficiency is enhanced by increasing the strain of the damper. Energy can be consumed efficiently from tiny vibration. Once the strain is beyond the designed strain of the damper, limiters are triggered to consume energy. Therefore, the overall performance of the damper tends to be stable, and excessive damping attenuation is not generated due to large deformation. The number of dampers used and the installation workload are reduced, and the overall cost is lowered.

Description

technical field [0001] The invention relates to the field of building anti-shock technology, in particular to a strain amplification device and a damper. Background technique [0002] The plate damper is composed of damping rubber and steel plate. It is installed on the building. When the structure is deformed due to horizontal action (earthquake, strong wind), the movement of the steel plate will cause the damping rubber to produce shear deformation. The damping rubber is in the process of repeated deformation. The energy transmitted from the outside is dissipated to achieve the effect of reducing the shaking tendency of the building structure. The plate damper has the characteristics of small strain energy consumption and small size, but due to the characteristics of its material, the energy consumption efficiency is not high when it is slightly deformed. This is because the energy consumption calculation formula of the viscoelastic damper is (where Wcj is the energy con...
