Description

A kind of assembling type steel structure Special-Shaped Column bean column node L-type cover plate connecting device
Technical field
The present invention relates to a kind of assembling type steel structure Special-Shaped Column bean column node L-type cover plate connecting device, belongs to Structural Engineering skill Art 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, supporting plate and ribbed stiffener are set in the lower flange of beam, also has L-type 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 L-type 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 assembling type steel structure Special-Shaped Column bean column node L-type cover plate connecting device, the device include post (A) and beam (B).
Described post (A) includes Special-Shaped Column (1), four ribbed stiffeners I (2), supporting plate (3) and two ribbed stiffeners II (4).Abnormity The form of post (1) is unlimited, can be T-shaped Special-Shaped Column, L-shaped Special-Shaped Column, cross Special-Shaped Column;Each ribbed stiffener (2) is welded on different In shape post (1), four ribbed stiffeners I (2) are respectively symmetrically welded on the distance between Special-Shaped Column opposite sides, homonymy ribbed stiffener I (2) The distance between upper lower flange equal to beam (B);Supporting plate (3) and two ribbed stiffeners II (4) are welded in Special-Shaped Column (1) edge of a wing one Side;There is bolt hole on Special-Shaped Column (1) and supporting plate (3), for being connected with beam (B).
The beam (B) include H profile steel beam (5), L-type steel plate I (6), four L-type steel plates II (7), two ribbed stiffeners III (8), Bolt (9).Two ribbed stiffeners III (8) are welded in L-type steel plate I (6);L-type steel plate I (6) and two L-type steel plates II (7) pass through spiral shell Bolt (9) is connected with H profile steel beam (5) top flange;H profile steel beam (5) lower flange passes through two other L-type steel plate II (7) and bolt (9) It is connected with supporting plate (3).
Described post (A) and beam (B) is connected by screw bolts, the L-type steel plate I (6) and two L-type steel plates of beam (B) top flange II (7) are connected with the side of Special-Shaped Column (1) prepared screw-bolt hole by bolt (9);Two L-type steel plates II (7) of beam (B) lower flange It is bolted with the edge of a wing of Special-Shaped Column (1) and supporting plate (3).
Special-Shaped Column (1), four ribbed stiffeners I (2), supporting plate (3) and two ribbed stiffeners II (4) weld to form post (A) in factory, Ribbed stiffener III (8) can also weld in the case where not influenceing bolt connection in factory, during later stage on-site consolidation, by post (A) and Installation bolt after the spiro keyhole position alignment of beam (B).
The invention has the advantages that in above-mentioned assembling type steel structure Special-Shaped Column bean column node L-type cover plate connecting device Realize live welding operation, bean column node of the invention sets supporting plate and ribbed stiffener in the lower flange of beam, at top flange There are L-type plate and ribbed stiffener, and be connected by bolt with beam.This connection may make up lever system, and ribbed stiffener can increase bottom plate With the bending resistance arm of force of L-type plate.Beam bottom plate can not only undertake a part of beam-ends moment of flexure, and can be accurately positioned beam, simultaneously Improve the stability of node.The invention belongs to be rigidly connected, the setting of ribbed stiffener, the rigidity and bearing capacity of node can be improved, 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 node, weak structure The design requirement of part ".The arrangement of bolt is also easy to operation in this connection, substantially increases assembling speed and construction quality. Scene uses bolts assemblies, and the fastening work of bolt is convenient and swift, and speed of application and quality greatly improve, and realize batch production Production, live quick assembling.
