Aseismic damper for wooden house formed of superplastic alloy

Abstract

The utility model provides a superplastic alloy shockproof damper (3) arranged at the joint part of a column (1) and a beam (2) of a timberwork residence in the direction of almost 45 degrees and used as a shockproof reinforcing device. The damper is composed of a circular narrow deformation part (31) curved with an approximately parallel width in the inner surface direction of the column-beam frame; and a supporting part (30) fully expanded to larger size for preventing both ends of the damper from deformation. In the structure of the damper, the deformation part of the superplastic alloy shockproof damper is combined with installation components (4) for fixing the supporting part at both ends of the shockproof damper at the joint part of the column and the beam of the residence; in order to achieve the same deformation (31) from the ends to the center of the deformation part, the section areas and the section coefficients from the ends to the center are gradually increased.

Description

technical field [0001] The present invention relates to an anti-seismic shock absorber which is mainly installed at the junction of columns and beams of wooden houses for anti-seismic reinforcement and achieved through superplastic alloys. Background technique [0002] The anti-seismic shock absorber used in the seismic reinforcement of wooden houses is expected to have the function of reducing the shaking of the house during an earthquake, avoiding damage to the house, and maintaining the soundness of human life and assets. [0003] Known anti-seismic dampers for wooden houses can be roughly classified into those using steel materials, those using viscoelastic materials, and those using oil dampers. [0004] For example, in the following patent documents 1 and 2, steel-based anti-seismic shock absorbers used for shaft groups of wooden houses are disclosed. [0005] Also, in Patent Documents 3 and 4, viscoelastic shock absorbers used for the shaft group of wooden houses are...

AI Technical Summary

Problems solved by technology

[0018] In the steel-based shock absorbers disclosed in the aforementioned Patent Documents 1 and 2, in the process of plastic deformation caused by earthquakes, etc., the yielding strength gradually changes due to repeated deformation, and the shock-absorbing performance changes accordingly. Stable situation. Therefore, the yield load increases due to the work hardening of the steel, and the elastic region of the material becomes longer after the second time, and the energy absorption performance becomes unstable. This is the case when using steel with an extremely low yield point In the case of shock absorbers is a significant characteristic.

[0019] Due to the deterioration of the mechanical properties of steel-based damping brakes during plastic deformation, it is difficult to grasp the performance during continuous use, and the necessity of inspection and replacement increases, resulting in a problem that requires considerable maintenance costs.

[0020] The viscoelastic shock absorbers disclosed in the above-mentioned patent documents 3 and 4 have a very large temperature dependence, and have poor heat dissipation when absorbing earthquake energy and generate heat. Since the strength is significantly reduced during repeated deformation, the shock absorbing performance becomes poor. Instable. When it is used in a general wooden structure house with a large difference in the outside temperature, the shock absorption performance is affected by the large difference in operating temperature due to seasonal factors such as winter and summer.

[0021] The oil-based vibration dampers disclosed in the above-mentioned patent documents 5 and 6 are implemented by a general linear motion mechanism. In order to ensure the smooth movement of the oil-based vibration damper, it is necessary to install a number of auxiliary components and accessories, which cannot be tightly accommodated. The structure of the junction between the column and the beam of the wooden structure house is not easy to reduce the cost. Therefore, due to the complicated structure of the linear motion mechanism, it becomes a high-priced item. However, attention must be paid to the deterioration of performance caused by oil leakage, and regular maintenance is required. , check, need a fee.
