Steel-wood combined rigid joint and building

Abstract

This utility model discloses a steel-wood composite rigid joint and its application in timber beam connections. The timber beams are divided into main beams and secondary beams, each consisting of left and right sections. The steel-wood composite rigid joint includes a first web, a second web, an upper flange, a lower flange, and pin-type fasteners. The upper and lower flanges are arranged in parallel, and the first and second webs are vertically fixed to the upper and lower flanges. The end of the second web is fixedly connected to the side of the first web. A first connecting groove is provided in the secondary beam, and a second connecting groove is provided in the main beam. The second web is placed in the second connecting groove, and the end of the first web is placed in the first connecting groove, connected as a whole by pin-type fasteners. In the joint area with the greatest bending moment and shear force, the steel mainly bears the force, improving the load-bearing capacity of the joint. The elasticity and toughness of the timber in the joint area can effectively absorb seismic energy, ensuring the seismic resistance requirements of strong joints and weak members.
