Description

A kind of T-shaped cover plate folder edge of a wing connection of assembling type steel structure quadrate steel pipe column bean column node Device
Technical field
The present invention relates to a kind of T-shaped cover plate folder edge of a wing attachment means of assembling type steel structure quadrate steel pipe column bean column node, category knot Structure field of engineering technology.
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, supporting plate and ribbed stiffener are set in the lower flange of beam, also has T-shaped plate at top flange and adds Strength rib, and be connected by bolt with beam.This connection may make up lever system, and ribbed stiffener can increase the bending resistance of bottom plate and T-shaped plate The 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 the stabilization of node Property.The invention belongs to be rigidly connected, the setting of ribbed stiffener, the rigidity and bearing capacity of node can be improved, make the position of destruction of a node Setting in the beam section outside this connection, so as to be played a protective role to node, meet the design requirement of " strong node, weak component ". The arrangement of bolt is also easy to operation in this connection, substantially increases assembling speed and construction quality.Scene is filled using bolt Match somebody with somebody, the fastening work of bolt is convenient and swift, and speed of application and quality greatly improve, and realizes factorial praluction, and scene is quick Assembling.
A kind of T-shaped cover plate folder edge of a wing attachment means of assembling type steel structure Special-Shaped Column 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 upper prop (1) and lower prop (2), i.e. ring flange (3) welding in factory In upper prop (1), another ring flange (3) is welded in lower prop (2), and bolt (6) connects two ring flanges (3), so as to by upper prop (1) Connected with lower prop (2);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), two T-steel plates (8), L-type steel plate (9), cover plate (10), ribbed stiffener II (11), bolt (6).T-steel plate (8) regards a level board as and a vertical plate is formed;Two cover plates (10) are welded in two T Shape steel plate (8), and the gap bigger than H profile steel beam (7) edge of a wing is left between the level board of cover plate (10) and T-steel plate (8);Installation When, first L-type steel plate (9) is positioned on the top of H profile steel beam (7) lower flange, then H profile steel beam (7) is positioned over supporting plate (3) On, and bolt hole is alignd;Then H types by two T-steel plates (8) and two cover plates (10) in place, and by bolt (6) are completed The connection of girder steel (7) and each component.
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;During later stage on-site consolidation, installation bolt after the spiro keyhole position of post (A) and beam (B) is alignd, put more energy into Rib II (11) need to be welded after two T-steel plates are in place.
The invention has the advantages that connect in the above-mentioned T-shaped cover plate folder web of assembling type steel structure Special-Shaped Column bean column node Connection device realizes live welding operation, bean column node of the invention, supporting plate and ribbed stiffener, upper limb is set in the lower flange of beam Also there are T-shaped plate and ribbed stiffener at edge, and be connected by bolt with beam.This connection may make up lever system, and ribbed stiffener can increase The bending resistance arm of force of bottom plate and T-shaped 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.
