Spring fixing device for shock-absorbing safety cabin and installation method thereof

Abstract

The invention discloses a spring fixing device for a shock-absorbing safety chamber and an installation method thereof, comprising a No. 1 connecting plate, a No. 2 connecting plate and a pressing plate. The pressing plate is located between the No. 1 connecting plate and the No. There are a number of positioning holes on the No. 2 connecting plate. The lower side of the No. 1 connecting plate is rotatably embedded with the No. 1 threaded rod. The middle part of the pressure plate is fixedly embedded with a threaded sleeve. The bottom end of the No. 1 threaded rod passes through the threaded sleeve. Both sides of the pressure plate and the threaded sleeve are slidably embedded with long bolts. The bottom ends of the long bolts pass through the No. 2 connecting plate and are threaded to the No. 1 nut, and the No. 2 connecting plate and the pressing plate are provided with two adjustment slots. No. 2 threaded rods are embedded in the adjustment grooves. The spring fixing device for the shock-absorbing safety warehouse of the present invention has the characteristics of reasonable structural design and good cushioning performance. In order to buffer the deformation energy of the spring and release it slowly, it can effectively reduce the shaking range of the upper and lower channel steel.

Description

technical field [0001] The invention relates to a spring fixing device, in particular to a spring fixing device for a shock-absorbing safety cabin and an installation method thereof, belonging to the technical field of shock-absorbing safety cabin construction. Background technique [0002] Building vibration reduction (structural energy dissipation and vibration reduction technology) is to install energy dissipation devices in certain parts of structures (such as supports, shear walls, joints or connectors), through which friction, bending (or shearing, torsion) ), elastic-plastic (or viscoelastic) hysteretic deformation to dissipate or absorb the energy input by the earthquake to reduce the seismic response of the main structure, thereby avoiding structure damage or collapse, and achieving the purpose of vibration control. [0003] During the assembly process of the shock-absorbing safety chamber, it is necessary to add a shock-absorbing structure to the longer channel ste...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a spring fixing device for a shock-absorbing safety chamber and its installation method, so as to solve the problem that the shock-absorbing structures proposed in the above-mentioned background technology are all fixed structures, and the springs cannot be replaced according to actual needs, and the stiffness of the springs cannot be adjusted. Adjustment, too large or too small spring stiffness will affect the shock absorption performance of the shock absorption structure, and it is difficult to achieve the best shock absorption effect
