The adopted stiffening boards are capable of improving bending resistance of the end portion of the node, rotating place of the node is adjusted, and the node is driven to rotate around the end portions of the stiffening boards.

Description

Internal partition formula concrete-filled steel square tubular column and H section steel beam structures with semi-rigid joints
Technical field
The utility model belongs to construction engineering technical field, relates to a kind of Steel concrete combining structure, specifically is applicable to concrete-filled steel square tubular column in many high-rise steel structure and the connected node of H section steel beam.
Background technology
At present, semi-rigid connection mainly couples together beam, post by high-strength bolt and connector (angle steel, T-steel and end plate), it is board-like that principal mode has bolt to connect overhanging end, do not connect the board-like connection of overhanging end, and flange of beam is connected with post jamb by connector.Wherein:
(1) it is board-like that bolt does not connect overhanging end, the girder steel that is welded end plate is connected with post by the high-strength bolt that bolt is welded on the steel pipe post jamb, this node is easy to cause the cripling of steel pipe post jamb, and the bolt Welding quality requirement of high-strength bolt and post jamb is high, switching performance is difficult for guaranteeing, bending rigidity is also little, therefore less in the application of engineering reality.
(2) it is board-like that bolt connects overhanging end, be that girder steel passes through welded end plate or T-steel (T-shaped connector also can be connected with girder steel with high-strength bolt), link to each other with post with the strength bolts of growing tall that connects shaft, after the concrete in managing reaches some strength, shank of bolt is applied prestressing force.This node has preferably ductility and anti-seismic performance, and node rigidity is large, applies with control ratio difficultly but the installation of building site in-and-out bolt, bolt are prestressed, because bolt need to run through steel core concrete column, site operation is also very inconvenient.(
(3) connector formula namely also is connected with steel core concrete column with high-strength bolt by connector (angle steel, T-steel and combined steel plate), and web links to each other with post with high-strength bolt by the vertical steel plate that is welded on the post.The flange of beam of this node has not only improved ductility and the anti-seismic performance of node because having adopted high-strength bolt, and has reduced the Site Welding amount, also is conducive to on-the-spot installation.But when connector under seismic loading repeatedly, owing to not having the internal partition power transmission in the steel pipe.Steel core concrete column easily causes the cripling of post jamb.
The utility model content
The purpose of this utility model is the anti-seismic performance for the connected node that improves concrete-filled steel square tubular column and H section steel beam, and a kind of novel joint with good deformability and energy dissipation capacity is provided, and prevents from causing collapsing of structure because connected node destroys.
For achieving the above object, the technical scheme that the utility model is taked is: it comprises concrete-filled steel square tubular column and H section steel beam, the web of H section steel beam is applied on the concrete-filled steel square tubular column by vertical junction plate and high-strength bolt, it is characterized in that, in the square steel tube wall corresponding to the upper and lower edge of a wing of H section steel beam, be respectively equipped with internal partition, be respectively equipped with horizontal connecting plate outside the square steel tube wall at place, the upper and lower edge of a wing of H section steel beam, horizontal connecting plate is fixed on the girder steel edge of a wing by high-strength bolt; Square steel tube wall at place, the upper and lower edge of a wing of H section steel beam is respectively equipped with stiffener, and horizontal connecting plate and stiffener form an angle connector and be welded on outside the concrete-filled steel square tubular column wall.
In order to guarantee Nodes concrete quality, establish air-vent four jiaos of internal partitions, its aperture is 25mm.
In order to make things convenient for the concrete filled construction, the pouring hole aperture on the internal partition should be not less than 200mm.
Compared with prior art, the beneficial effect of the utility model node is:
1, connect with high-strength bolt by junction plate between the utility model beam-column, construct fairly simple, site operation is also very convenient, junction plate is finished in factory welding, reduces the Site Welding amount.
2, place internal partition in the utility model center pillar, the power transmission route is clearly reliable, under seismic loading repeatedly, can avoid the cripling of concrete-filled steel square tubular column wall.
3, the connection owing to beam, intercolumniation is that bolt connects entirely in the utility model, and deformability is strong, and stress performance is reliable.
4, be the impact of avoiding the rotation butt welded seam of girder steel, adopt the stiffener mode with enhancing node end bending resistance, thereby the position that knot modification rotates make node rotate around the stiffener end.
5, Semi-rigid Joints has good deformability and energy dissipation capacity, by control beam-ends plastic hinge dissipation seismic energy, prevents from causing collapsing of structure because connected node destroys.
