Shock absorption node and building steel structure thereof

Abstract

The invention provides a shock absorption node and a building steel structure thereof. The shock absorption node comprises buffering bases and a node connecting frame, wherein the node connecting frame is arranged in the two buffering bases, guiding rails are arranged in supporting frames 11 in the buffering bases, sliding blocks are installed in the guiding rails, springs are movably installed between the sliding blocks and the side faces of the guiding rails, middle plates are hinged to the sliding blocks through connecting rods, screw rods are correspondingly installed in the guiding rails,threaded sleeves sleeve the two ends of the screw rods correspondingly, friction rods are fixedly installed on the side faces of the sliding blocks, and the friction rods make frictional contact withthe threaded sleeves. Through the hinged relation between the sliding blocks and the connecting rods, the middle plates can freely move on the horizontal plane formed by the buffering bases, so thatthe effect of multi-angle buffering and damping is achieved, the sliding blocks drive the friction rods to move synchronously with the sliding blocks in the moving process, and then the friction rodsdrive the threaded sleeves to move along the screw rods, the effect of limiting the positions of the sliding blocks is achieved, the excessive displacement of the sliding blocks is avoided, and the supporting effect is achieved.

Description

technical field [0001] The invention relates to the technical field of steel structure components, in particular to a shock-absorbing node and its building steel structure. Background technique [0002] With the continuous development of the construction industry, many of the existing building systems use assembled steel structure components, and the steel structure needs to be connected by connecting nodes. For example, a new building steel structure node provided by the publication number CN208088505U realizes steel frame connection, but this node connection is through a rigid connection. When the overall structure is subjected to a rigid impact, the shock absorption cannot be performed, and the connection strength needs to be considered when the steel structure building node is shock-absorbed. Therefore, the existing technology only considers the connection strength. There is no shock absorption involved. Contents of the invention [0003] The object of the present inv...
