Problems solved by technology

In the connection of steel splints and hidden steel plates, due to the difficulty of bolt insertion, the joints are prone to transverse grain cracking; while the connection of planted reinforcement joints requires on-site glue application and maintenance, the strength is not easy to guarantee, and it takes a long time to occupy the scaffolding, resulting in construction Complicated and long construction period

Abstract

A fabricated steel-wood structure connecting joint comprises columns and beams. Short inverted-T-shaped steel connecting pieces are inserted into the ends of the beams, long bolts penetrate into the columns, one end of each long bolt is connected with the corresponding short inverted-T-shaped steel connecting piece, webs of the short inverted-T-shaped steel connecting pieces are connected with cover plates through short bolts, and the cover plates are arranged on the upper portions of the beams. The fabricated steel-wood structure connecting joint adopts the short inverted-T-shaped steel connecting pieces and has the advantages of great bearing capacity, joint stiffness, energy dissipation capacity and ductility performance.

Description

Technical field [0001] The invention relates to a wooden structure node of a building structure, in particular to a fabricated steel-wood structure connection node. Background technique [0002] According to a large number of experimental research and engineering case analysis, it is found that most of the damage of wood structure occurs at the joints, and the main reason for the damage is the insufficient bearing capacity, stiffness or ductility of the joints. Take the commonly used pin-bolt connection as an example. Usually, the pin-bolt connection is mainly borne by the bearing of the pin bolt and other fasteners and the bearing pressure of the wood pin groove. If the number of fasteners is small, the bending capacity and rotation of the node The rigidity is limited and can only be used for simple support or hinged connection; if the number of fasteners is large, it is easy to cause the node area to be too large, and at the same time cause the brittleness of the node failure m...
