Technical field
The utility model relates to the frame joint in a class building structure, is specifically related to a kind of rectangular steel-tube concrete column and the monolateral bolt connection node of girder steel.
Background technology
Stiffener ring plate rigid joint is a kind of joint form be most widely used in steel pipe concrete column-steel beam node, this category node has that bearing capacity is high, rigidity is large, the Path of Force Transfer succinctly advantage such as clearly, but the Site Welding workload of this category node is large, weldquality not easily ensures, steel pipe concrete column-steel beam structures with semi-rigid joints therefore with bolts is just causing the concern of more and more researcher and engineer.And steel pipe is closed cross-section, plain bolt is difficult to directly apply in tubular structure, and this causes the form of steel pipe concrete column-steel beam structures with semi-rigid joints with bolts less.The appearance of unilateral bolt fastener, can overcome the above problems well, and such bolt has the advantages such as monolaterally tighten, easy construction, stress performance are reliable.But easily there is cripling under the effect of the rectangular steel pipe tube wall point load outside face be directly connected with monolateral bolt to destroy, therefore adopt the bearing capacity of monolateral bolted steel pipe concrete column-steel beam node, rigidity, ductility and energy dissipation capacity all poor.Therefore be necessary to take certain construction measure to improve the local stability of rectangular steel pipe tube wall near bolt join domain, thus improve the mechanical property of this category node, promote applying of this category node.
Utility model content
The purpose of this utility model is the defect existed for the monolateral bolted steel pipe concrete column-steel beam node of existing employing, provide that a kind of bearing capacity is high, succinct clear and definite, the simple structure of power transmission, construct steel core concrete column and the monolateral bolt connection node of girder steel quickly and easily.
The scheme that the utility model technical solution problem adopts is, a kind of rectangular steel-tube concrete column and the monolateral bolt connection node of girder steel, comprise rectangle steel tubing string and girder steel, described girder steel welding edges has end plate, described end plate is mounted on steel pipe column sidewall by securing member, described end plate longitudinally offers some corresponding bolts hole in pairs with on steel pipe column, and described steel tubular column joints core space is provided with and adds competent structure.
Further, described securing member is monolateral bolt.
Further, described reinforcement is configured to any one in binding bar, external reinforcing plate for car or built-in short H profile steel.
Further, described external reinforcing plate for car is made up of two blocks of channel-section steels, described built-in its breadth of section of short H profile steel and be highly all slightly less than steel pipe column cross section inside wall width and height, its length is slightly larger than girder steel depth of section.
Further, described channel-section steel web place offers some bolts hole matched with girder steel and end plate in pairs.
Further, described steel pipe column section form is rectangle cold-bent pipe or rectangle straight seam welded steel pipe.
Compared with prior art, the utility model has following beneficial effect: such novel joint bearing capacity is high, plasticity ductility is good, energy dissipation capacity is high, mechanical property is reliable; Compared with adopting the rigid joint of outer annular-stiffer, such steel core concrete column and the monolateral bolt connection node of girder steel do not need Site Welding, and manufacturing procedures all except concreting all completes in factory, and therefore crudy is more reliable; Such steel core concrete column and the monolateral bolt connection node of girder steel, have the advantage that in-site installation is convenient, speed of application is fast, is conducive to realizing engineering construction standardization and produces, remarkable in economical benefits.
