Embodiment

[0015] In this embodiment, Type HB-Hollo-Bolt one-way self-tightening bolts produced by the British Lindapter Company are used. First, position and install the steel pipe of the CFST column; then directly insert a new type of one-way self-tightening bolt into the connection hole between the steel pipe column wall and the end plate (the end of the steel beam is fixed on the end plate), and the bolt head is on the inside of the steel pipe The riveting head is automatically formed, the joint is fastened and there is no need to reach into the inner side of the steel pipe for operation; finally, concrete is poured into the steel pipe column to form a steel pipe concrete column-steel beam connection node structure.

[0016] The technology of the present invention can be applied to the connection of frame columns with circular, square and rectangular cross-section concrete-filled steel pipe columns (processing technology is casting, rolling, cold bending and welding) and steel beams (...

Abstract

The invention relates to an end plate steel tube concrete post-steel beam connecting node, wherein said node is new beam post connecting node, whose cylinder section shape comprises round, square and rectangle; the section shape of steel beam comprises H and I shapes; the end part of steel beam is mounted on the end plate; when constructing the node, directly inserting one-way locking bolt into the steel tube post wall and end plate hole; the head of bolt has self support function; forming rivet head at the inner side of steel tube; at last, pouring concrete into steel tube post, to form said inventive node. The inventive node has better bearing function and anti-vibration property, with simple structure, simple operation, and easy installment.

Description

technical field [0001] The invention relates to a novel steel pipe concrete column-steel beam connection node, which belongs to the technical field of structural engineering. [0002] It has good mechanical performance and seismic performance, simple structure, clear force transmission, convenient structural layout, fast construction, and can solve the problem that high-strength bolts are not suitable for construction in the joint area; it is easy to disassemble and replace, and is convenient for building structure reinforcement and reconstruction. Background technique [0003] At present, the construction of the connection joint between the concrete filled steel pipe column and the steel beam is relatively complicated. In order to meet the rigid connection requirements of the beam column, welding or bolt welding is mainly used, and the end of the steel beam is fixed on the end plate, and the long bolt Through the connection method of rectangular steel tube concrete column, ...
