Abstract
The invention relates to a rectangular concrete filled steel tube column and steel beam single-side bolt connecting joint and a construction method of the rectangular concrete filled steel tube column and steel beam single-side bolt connecting joint. The connecting joint comprises a rectangular steel tube column and a steel beam, an end plate is welded to the end of the steel beam and fixedly installed on the side wall of the steel tube column through fasteners, and multiple corresponding bolt holes are longitudinally formed in the end plate and the steel beam in a pairwise mode. A reinforcement structure is arranged in the joint core region of the steel tube column. Compared with the prior art, the novel connecting joint has the advantages that the bearing capacity is high, the plasticity and ductility are good, the energy-dissipation capacity is high, and the mechanical property is reliable; compared with a rigid joint where an outer reinforcement ring is adopted, the concrete filled steel tube column and steel beam single-side bolt connecting joint does not need to be welded on site, all the machining processes, except for concrete pouring, are finished in a factory, and therefore machining quality is more reliable; the concrete filled steel tube column and steel beam single-side bolt connecting joint is convenient to install on site and high in construction speed.
Description
Technical field
The present invention relates to the frame joint in a class building structure, be specifically related to the monolateral bolt connection node of a kind of rectangular steel-tube concrete column and girder steel and construction method thereof.
Background technology
Strengthening ring type rigid joint is a kind of joint form being most widely used in steel pipe concrete column-steel beam node, this category node has that bearing capacity is high, rigidity is large, the succinct advantage such as clearly of Path of Force Transfer, but the Site Welding workload of this category node is large, weldquality is difficult for guaranteeing, so steel pipe concrete column-steel beam structures with semi-rigid joints with bolts is just causing more and more researchers and engineer's concern.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 monolateral 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 being directly connected with monolateral bolt, destroy, therefore adopt bearing capacity, rigidity, ductility and the energy dissipation capacity of monolateral bolted steel pipe concrete column-steel beam node all poor.Therefore be necessary to take certain construction measure to improve near the local stability of the rectangular steel pipe tube wall of bolt join domain, thereby improve the mechanical property of this category node, promote applying of this category node.
