Abstract

The invention relates to butterfly type self locking connecting card with friction shear resistant plate and building iron joint of framework structure. The friction shear resistant plate includes friction surface and shear resistant plate. Four friction shear resistant plates is formed square type node pillar to cooperate with hitch clevis. The connecting card includes card body. Both end of thecard body are respectively set two card wings with door shape cross section. The card wing includes bearing plate, pretension plate, and self locking mounting plate. The self locking and pretension plate are set through holes. The invention utilizes the friction, and self locking principle, the friction shear resistant plate is gain the enlarged pressure and friction by butterfly type self lockingconnecting card to transfer to bearing force to act on node crossbeam to gain ideal joint intensity, stiffness, and bearing force.

Description

technical field [0001] The invention relates to a building structure and its connectors, in particular to a building steel frame node structure. Background technique [0002] In the steel frame of a building, square steel pipe columns are used for the vertical beams, and "H"-shaped steel beams or "I"-shaped steel beams are used for the cross beams. The connection quality between the two is the key to the structural bearing capacity and earthquake resistance. The traditional steel structure node connection generally adopts butt joint welding or welding and bolt joint connection. The disadvantage is that the stress transmission is poor, it is difficult to release, it is easy to cause stress concentration, and the local damage is large. The mechanical properties depend on the material and wall thickness of the column. And poor economy. [0003] The ZL02235905.2 utility model discloses a "butterfly self-locking connection card", which includes a card main body, and two parallel...
