Embodiment Construction

[0032] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 , The building steel frame node connection structure described in the present invention includes a vertical column 1, a beam 2, a connection clip 3 and a frictional shear plate 11 or 12 connecting the two. The V-shaped friction shear plate 11 includes a V-shaped friction plate 14. At the same end of the two outer surfaces of the V-shaped friction plate, there is a shear plate 13 perpendicular to the outer surface, with holes on it. The whole component is called V-shaped friction shear plate 11 . If it is matched with the cylinder, the inner side of the original structure called V-shaped friction shear plate 11 is connected with an arc-shaped friction plate with the same arc radius as the cylinder, which is called C-shaped friction plate 15, and the original V-shaped friction plate 14 is It is called friction support plate 16 . The C-type friction plate 15 with the friction support plate 16 ...

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 the card 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 locking connecting 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 butterfly-shaped self-locking connecting clip and a building steel frame node connection structure matched with a frictional shear plate for a building steel frame node. 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 horizontal beams. The connection quality of 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] T...
