Description

Tensile limiting device

Technical Field

The application relates to the technical field of building shockproof, in particular to a tensile limiting device.

Background

The damage of earthquake to buildings is mainly caused by longitudinal waves and transverse waves of earthquake. The longitudinal waves cause the house building to bump up and down, when the earthquake force is large, the bearing structure can increase a large dynamic load instantly, the dead weight of the upper part is superposed, and when the bearing capacity of the bearing structure is exceeded, the building can be collapsed. The transverse wave makes the building swing horizontally, the destructive power is very large, which is equivalent to applying repeated action force to the building in the horizontal direction, and when the deformation in the horizontal direction exceeds the deformation limit of the bottom wall body, the whole building is inclined or toppled, so that the damage is caused.

The shockproof device that adopts at present is mostly rubber shock insulation support, and rubber shock insulation support is formed by multilayer steel sheet and the alternating coincide of rubber, and the steel sheet has changed the less characteristics of the vertical rigidity of the rubber body as the stiffening material of rubber support, makes it can reduce horizontal earthquake effect, can bear great vertical load again. At present, rubber shock insulation supports are generally uniformly distributed on a frame beam at the bottom of a building to form a shock insulation layer.

Aiming at the related technologies, after the inventor conducts multiple earthquake simulation experiments, the inventor finds that when an earthquake occurs, the earthquake-proof building is influenced by the earthquake to generate overturning bending moment, so that one side of the earthquake-proof support outside the building is pressed downwards and the other side of the earthquake-proof support is pulled upwards, and the pulling force is fatal to the earthquake-proof support because the tensile bearing capacity of the earthquake-proof support is very low. When the vibration isolation support is damaged, the building can be overturned and collapsed, and huge economic loss is caused.
