the specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Fig. 1-Fig. 4, the invention provides the bushing type node of a kind of concrete-filled steel square tubular column and steel I-beam, mainly by post limb 1, post jamb sleeve pipe 2, bone ellbeam end 3, edge of a wing side plate 4 and steel I-beam 5, formed; Outer wall at steel core concrete column post limb 1 is provided with post jamb sleeve pipe 2, and steel core concrete column connects steel I-beam 5 by described bone ellbeam end 3, auxiliary bone ellbeam end 3 and the post jamb sleeve pipe 2 of connecting of edge of a wing side plate 4.
Post limb 1 is connected by weld seam with post jamb sleeve pipe 2, and post jamb sleeve pipe 2 is connected by weld seam with bone ellbeam end 3 and edge of a wing side plate 4.
Post limb 1 can be connected by upper, middle and lower three road weld seams with post jamb sleeve pipe 2, to bear shearing and the moment of flexure of beam.
Between bone ellbeam end 3 and steel I-beam 5, be edge of a wing welding and soldered the connecing of the bolted bolt of web.
This joint structure of the present invention is simple, can prefabrication, improve work situation, improve the quality of production; Analysis shows, supporting capacity is high, and hysteresis loop is full and be almost completely spindle, and energy dissipation capacity is large, and ductility of joint is good, can meet the Seismic Design Requirements of node, can be used in multilayer or little high residential building.
The processing method of this node structure is: 1. calculate post jamb casing size, determine thickness, length and the weld size of sleeve pipe.The wall thickness suggestion of sleeve pipe is got , wherein t c , t f be respectively column jecket wall thickness and the steel I-beam edge of a wing is thick; The height suggestion of sleeve pipe is got , wherein h b , that D is respectively the post of steel I-beam depth of section and steel core concrete column is wide, h d for sleeve pipe exceeds beam face height.Interior chamfering is processed at sleeve pipe two ends and post jamb forms monolateral double V-groove welding, and sleeve pipe middle part can process some sections of oval grooves and post jamb formation slot weld according to bearing capacity calculation.Sleeve pipe can be strengthened in node area, first not drawn badly with guard column, improves the out-of-plane flexing that post jamb plate tension causes, by sleeve pipe, can effectively bear flange of beam pulling force, improves significantly Hysteresis Behavior, improves energy dissipation capacity.2. calculate bone ellbeam end size, determine radius, action and the chord length of bone shape.Parameter and the size value of beam-ends Gu Xing junction are as follows: , , , .The bone shape that node adopt to weaken beam-ends connects, and when advantage is to occur to shake greatly, guides artificially plastic hinge to occur in beam-ends weakening place, avoids weld seam junction stress excessive and destroy; Improved the ductility of node, plastic hinge still has stable Elastoplastic Performances in Simulation and good energy dissipation capacity after occurring.③ factory completes the welding of post jamb sleeve pipe, bone ellbeam Duan, edge of a wing side plate.The side plate on the beam-ends edge of a wing, can avoid stress to concentrate, guarantee that the axial stress of flange of beam evenly passes on post side plate.4. on-the-spot opsition dependent is put rear welded post limb and post jamb sleeve pipe well, and other complete by normal construction step, and bone ellbeam end is connected with steel I-beam, pouring concrete.
