AI Technical Summary

⚠Technical Problem

Traditional prefabricated building wall connection methods have insufficient seismic performance when facing earthquakes, and the construction period is long. The lack of vibration damping mechanisms between walls leads to rigid contact, which increases the risk of structural damage.

⚗Method used

The damper, which is connected to the base and the L-shaped structure, combines a dual locking mechanism of threaded column, gear meshing and locking and shock-absorbing spring. The damper absorbs vibration energy through an array of distributed dampers. The number of threaded holes can be flexibly selected to adapt to different building needs. The guide mechanism ensures the stable movement of the lifting plate.

🎯Benefits of technology

It effectively absorbs ground vibration energy, ensures the stability of connection points, reduces seismic damage, shortens construction time, adapts to different building needs, and is suitable for outdoor and humid environments.

Abstract

The utility model relates to the technical field of assembly type building construction, concretely is a kind of assembly type building wall body anti-seismic connecting node structure, including pedestal and the L-shaped structure on the pedestal, and the L-shaped structure is connected with the damper between the pedestal;The bottom end of the pedestal is provided with embedded part, the L-shaped structure includes horizontal L-shaped plate and vertical L-shaped plate that is vertically arranged on the horizontal L-shaped plate;The vertical L-shaped plate includes two fixed plates connected in right angle, the outside of two the fixed plate is respectively fixed with assembly box, each the fixed plate is all provided with the threaded hole that is connected with the inside of assembly box, threaded column is arranged on the threaded hole, and the threaded column is located on the end in the inside of assembly box and is equipped with handle and gear, the inside of assembly box is also provided with lifting plate, locking mechanism, damping spring and guide mechanism. Through the energy dissipation effect of damper, wall body can consume energy by displacement and deformation in earthquake, rather than directly transmitting rigid impact.
