Steel frame building wall with shock-absorbing joints and its construction method

Abstract

The invention discloses a steel frame building wall with shock-absorbing nodes and a construction method thereof. The steel-frame building wall with shock-absorbing nodes includes wall panels, steel frame beams and shock-absorbing nodes, and the shock-absorbing nodes Including the upper node and the lower node; the upper node includes a Z-shaped steel plate, one end of the Z-shaped steel plate has a first round hole, and the other end has a long hole along the width direction of the Z-shaped steel plate, and the first bolt passes through the first round hole It is connected with the upper surface of the steel frame beam, and the second bolt passes through the oblong hole to connect with the upper end surface of the wall panel; the lower node includes a steel support, which is connected to the upper surface of the steel frame beam, and the steel support is opened with The second round hole, the third bolt passes through the second round hole and is connected with the lower end surface of the wallboard, and the third bolt is covered with a spring. Compared with the prior art, the steel frame building wall body with shock-absorbing nodes has good shock-absorbing effect, reduces economic losses after earthquakes, and can be repaired quickly.

Description

technical field [0001] The invention relates to the field of construction, in particular to a steel frame building wall with damping nodes and a construction method thereof. Background technique [0002] The walls of steel frame buildings generally include steel frame beams and wall panels, and the connection nodes between wall panels and steel frame beams are key factors in the seismic design of steel frame buildings. Under earthquake action, the wall panel is a displacement-sensitive non-structural component inside the plane, and an acceleration-sensitive component outside the plane. Because the in-plane ductility of wall panels is generally lower than that of steel frame beams, if the connection nodes between wall panels and steel frame beams are treated as in-plane rigid connections, under the action of coordinated deformation with steel frame beams, wall panels usually When the interstory displacement of the beam is not large, in-plane cracking damage or even collapse ...

AI Technical Summary

Problems solved by technology

Rigid connection nodes are usually used in the existing technology, and wall panels contribute greatly to the stiffness and bearing capacity of steel frame beams. On the one hand, it will increase the overall stiffness of the structure, change the stiffness and bearing capacity distribution of the structural system, and may have adverse effects on the structure's seismic resistance ; On the other hand, it is also easy to cause the wall panels to be damaged before the steel frame beams, resulting in economic losses
