Penetrating through the center of the bracket, the telescopic spring is composed of a conductive angle, a spring, a telescopic rod, a pillar, a steel cap, and a damping pad. The invention is a thermal insulation gasket, and the spring and the damping pad are fixed inside the bracket through the conductive angle. , when the operator installs the heat insulation gasket in the connection gap of the mechanical equipment, the damping pad will drive the telescopic rod to press down the spring, and the support will be embedded in the steel cap to prevent the telescopic spring from twisting and bending; it will be replaced next time When the spring is not under pressure, it will automatically bounce outwards to keep the telescopic spring horizontal and vertical, so that it can be used repeatedly and solve the problem of frequent replacement of heat insulation gaskets.

Shear wall structure with rectangular steel pipe rows with vertical gaps
ActiveCN106677380BAvoid instabilityIncreased out-of-plane stiffnessWallsClassical mechanicsEngineering
The invention discloses a rectangular steel pipe row shear wall structure with vertical gaps. It is mainly composed of a plurality of vertically arranged rectangular steel pipes closely arranged horizontally and horizontally. The adjacent rectangular steel pipes are connected by connecting welds arranged at intervals, and the connecting welds at the junction of the steel pipe flange and the web Two adjacent steel pipes are connected. The vertical discontinuity of the connection weld forms a vertical gap between the rectangular steel pipes, and the rectangular steel pipes between the parallel vertical gaps form a small bending column, which bends and deforms under the action of the lateral load, so that the shear wall is under load. The plastic hinge formation at the end of the lower flexural column occurs before the overall instability of the shear wall, the out-of-plane instability of the flexural column and the local instability of the steel pipe wall. The invention has the characteristics of large anti-lateral bearing capacity, large out-of-plane rigidity, large anti-lateral rigidity, good seismic performance, good ductility, full energy consumption hysteresis loop and the like.
