Telescopic building steel structural connecting part

Abstract

The invention discloses a telescopic building steel structural connecting part, and relates to the technical field of building construction. The telescopic building steel structural connecting part comprises I-shaped steel and a plurality of T-shaped sliding blocks, a connecting plate is fixedly connected to one end surface of the I-shaped steel and one end surfaces of the T-shaped sliding blocks,the T-shaped sliding blocks are connected to the surfaces of the two sides of the I-shaped steel in a sliding mode, and a plurality of sliding grooves are formed in the T-shaped sliding blocks. According to the telescopic building steel structural connecting part, by using kidney-shaped holes, threaded holes and fastening screws, when the connecting part is impacted by external force after beingfixed, fixing bolts keep still, the kidney-shaped holes slightly slide left and right relative to the fixing bolts, so that the T-shaped sliding blocks slightly swing, the buffering effect is improved, the situation of stress concentration is avoided, and therefore the fixing bolts are protected, and the service life of the fixing bolts is prolonged; and by using air bags, sliding rods, air inletchannels and air outlet channels, when the T-shaped sliding blocks slide left and right, the sliding rods can extrude the air bags, the air bags can blow air into the kidney-shaped holes through air blowing channels, and the overheating fatigue of fastening bolts and other structural parts under severe friction can be avoided.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a scalable building steel structure connector. Background technique [0002] Steel members refer to steel structural composite members that can bear and transmit loads and are connected by steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams, cold-bent or welded through connectors. The steel component system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. The unique advantages of the three aspects of development, in the world, especially in developed countries and regions, steel components have been widely used in the field of construction engineering. Practice shows that the greater the force, the greater the deformation of steel components. However, when the force is too large, t...

Problems solved by technology

[0004] The purpose of the present invention is to provide a flexible building steel structure connector, which solves the problem that the existing steel members generally adopt welding and bolt connection when connecting, which will bring great load to the weld or bolt connection. Stress concentration is prone to occur, which affects the service life
