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
