Description

A kind of T-shaped cover plate connecting device of assembling type steel structure quadrate steel pipe column bean column node
Technical field
The present invention relates to a kind of T-shaped cover plate connecting device of assembling type steel structure quadrate steel pipe column bean column node, belongs to Structural Engineering Technical field.
Background technology
Assembling type steel structure system refers to the building subassembly specification making house unit or component according to unification, standard, so After be transported to job site and assemble building in place and caused.It is characterized in that construction quality light, energy-conserving and environment-protective, speed of application be fast, work Industry degree height etc., can solve that building industrialization level is low, house building labor productivity is low and conventional house product quality Low problems, adapt to the development of China's building trade.
Bean column node is most important node in assembling type steel structure system, it directly affect the speed of application of structure with And assembling degree, therefore bean column node should try one's best and use high strength exploitation easy to operation more, and the arrangement of bolt The fastening of worker scene should be possibly easy to, the bean column node used in existing case history has the following disadvantages:Traditional beam Post is welded in node entirely, lower flange and web and welding of post scene on beam, although this connected mode is is rigidly connected, node prolongs Property it is poor, brittle break easily occurs in earthquake, and needs on-the-spot welding, leverages speed of application and quality, without using in In more high-rise assembling type steel structure, simultaneously because bonding area is big, larger residual stress is easily produced, influences the stress of node Performance.In tradition bolted and welded connection node, lower flange and post Site Welding, web plate pass through shear plate and stud on beam-ends Connect, this connected mode needs on-the-spot welding, leverages speed of application and quality, and operational procedure is complicated, it is not easy to real Now it is rigidly connected.
The content of the invention
The defects of it is an object of the invention to overcome prior art, meet node items mechanical property, realize bean column node Be rigidly connected, realize the assembling of structure, improve the assembled speed of component, fully adapt to assembling type steel structure system requirement With feature.The bean column node of the present invention, L-type plate, supporting plate and ribbed stiffener are set in the lower flange of beam, have at top flange T-shaped plate with And ribbed stiffener, and be connected by bolt with beam.This connection may make up lever system, and ribbed stiffener can increase bottom plate and L-type plate The bending resistance arm of force.Beam bottom plate can not only undertake a part of beam-ends moment of flexure, and can be accurately positioned beam, while improve node Stability.The invention belongs to be rigidly connected, the setting of ribbed stiffener, the rigidity and bearing capacity of node can be improved, makes destruction of a node Position be located at beam section outside this connection, so as to being played a protective role to node, the design for meeting " strong node, weak component " will Ask.The connection of this node is adapted to top to have the connection of ring flange ring flange, the presence of ring flange, square tube post bean column node can be achieved Bolt connection.The arrangement of bolt is also easy to operation in this connection, substantially increases assembling speed and construction quality.Adopt at scene With bolts assemblies, the fastening work of bolt is convenient and swift, and speed of application and quality greatly improve, and realize factorial praluction, Live quick assembling.
A kind of T-shaped cover plate connecting device of assembling type steel structure quadrate steel pipe column post bean column node, the device include post (A) and beam (B)。
Described post (A) include upper prop (1), lower prop (2), two ring flanges (3), supporting plate (4), two ribbed stiffeners I (5) and Bolt (6).Supporting plate (4) and two ribbed stiffeners I (5) are welded in lower prop (2) side, and set bolt hole in this side, for The connection of beam (B);Two ring flanges (3) are respectively welded in factory and connect two flanges in upper prop (1) and lower prop (2), bolt (6) Disk (3), so as to which upper prop (1) and lower prop (2) be connected;Supporting plate also is provided with bolt hole on (4), for the connection with beam (B).
The beam (B) includes H profile steel beam (7), T-steel plate (8), L-type steel plate (9), two ribbed stiffeners II (10), bolts (6).Two ribbed stiffeners II (10) are welded in T-steel plate (8);T-steel plate (8) passes through bolt (6) and H profile steel beam (7) top flange Connection;H profile steel beam (7) lower flange is connected by L-type steel plate (9) and bolt (6) with supporting plate (4).
Described post (A) and beam (B) is connected by screw bolts, and the ring flange of upper prop (1) and lower prop (2) does not connect first during construction Connect, be first connected beam (B) by bolt (6) with lower prop (2), the T-steel plate (8) and L-type steel plate (9) of beam (B) top flange are with The side of post (2) prepared screw-bolt hole is connected by bolt (6);Two L-type steel plates (9) of beam (B) lower flange and the wing of lower prop (2) Edge and supporting plate (4) are bolted;Finally by two ring flanges (3) of bolt connection.
Upper prop (1) and ring flange (3) weld in factory, lower prop (2), ring flange (3), supporting plate (4) and two ribbed stiffeners I (5) welded in factory;Ribbed stiffener II (10) can also be welded in T-steel plate in the case where not influenceing bolt connection in factory (8), during later stage on-site consolidation, full bolt splicing.
The invention has the advantages that in the above-mentioned T-shaped cover plate connection dress of assembling type steel structure quadrate steel pipe column bean column node Putting realizes live welding operation, bean column node of the invention, and L-type plate, supporting plate and ribbed stiffener are set in the lower flange of beam, on Also there are T-shaped plate and ribbed stiffener at the edge of a wing, and be connected by bolt with beam.This connection may make up lever system, and ribbed stiffener can increase Add the bending resistance arm of force of bottom plate and L-type plate.Beam bottom plate can not only undertake a part of beam-ends moment of flexure, and beam can be made accurately fixed Position, while improve the stability of node.The invention belongs to be rigidly connected, the setting of ribbed stiffener, can improve node rigidity and Bearing capacity, the position of destruction of a node is located at this beam section outside connecting, so as to be played a protective role to node, meet " strong section The design requirement of point, weak component ".The arrangement of bolt is also easy to operation in this connection, substantially increases assembling speed and work Cheng Zhiliang.Scene uses bolts assemblies, and the fastening work of bolt is convenient and swift, and speed of application and quality greatly improve, and realizes Factorial praluction, live quick assembling.
