Abstract
The utility model discloses an angle steel connection type semi-rigid node for a square steel tube concrete column and a steel beam. The angle steel connection type semi-rigid node is characterized in that inner clapboards are respectively welded in the wall, corresponding to the upper flange and the lower flange of the steel beam, of a square steel tube, angle steel connecting pieces are respectively welded on the outer wall, corresponding to the upper flange and the lower flange of the steel beam, of the square steel tube, and the upper flange and the lower flange of the steel beam are respectively connected with respective angle steel connecting pieces through high strength frictional bolts. The angle steel connection type semi-rigid node not only can effectively transmit all beam-end shearing force, but also can transmit part bending moment so as to effectively control a beam end to form plastic hinge and better dissipate seismic energy.
Description
Technical field
The utility model belongs to a kind of Steel concrete combining structure, specifically is a kind of concrete-filled steel square tubular column and girder steel Semi-rigid Joints form.
Background technology
U.S. Northbridge in 1994 earthquake that in succession occurs and nineteen ninety-five Japan Kobe earthquake etc. repeatedly earthquake show, adopt that the steel frame weld rigid joint fully is poor because of ductility of joint, residual stress is large, brittle fracture easily occurs, thereby causes earthquake zone steel building disaster quite serious.In recent years, Concrete-Filled Square Steel Tube is simple because of joint form, and second moment of area is large, good stability, the distinct advantages such as be convenient to take precautions against fire, and uses increasingly extensive.But these Concrete Filled Square Steel Tubular Frame structure node structures are close with steel framed structure, therefore, also have the problems such as ductility of joint is poor, welding residual stress is large, equally easily occur brittle fracture under geological process.
Studies show that, deformability and energy dissipation capacity that Semi-rigid Connection Steel Frame is stronger because node has, natural vibration period that can extending structure, by the control beam-ends plastic hinge seismic energy that can dissipate, prevent from causing collapsing of structure because connected node destroys, thereby greatly reduce earthquake, be conducive to antidetonation.Therefore research structures with semi-rigid joints new model, seismic design the applying in Practical Project of realizing ductility joint, significant.
The utility model content
The purpose of this utility model is in order to promote the application of Steel concrete combining structure in highrise building, a kind of new ductile structures with semi-rigid joints form that is conducive to structural seismic is provided, can effectively transmit whole Shear force within the beam ends, again can the transmitting portions moment of flexure, effectively the control beam-ends forms plastic hinge, and seismic energy better dissipates.
In order to realize above-mentioned node new model, the technical scheme of taking of the present utility model is: be welded with respectively internal partition in the square steel tube wall at the place, the upper and lower edge of a wing corresponding to girder steel, be welded with respectively angle iron connecting piece on the square steel pipe outer wall at place, the upper and lower edge of a wing of girder steel, the upper and lower edge of a wing of girder steel is connected on separately the angle iron connecting piece by high strength frictional property bolt respectively.
Above-mentioned upper and lower angle iron connecting piece and square steel tube wall all preferably adopt the fillet weld connected mode.
Compared with prior art, the utlity model has following advantage:
1, the welding internal partition effectively transmits pulling force and the pressure of bottom flange on the girder steel, has direct, the clear and definite characteristics of power transmission.Compare the external partition joint form, have the advantages such as the steel of saving, assurance architectural space.
2, the bottom flange is connected with the square steel tube wall by angle iron connecting piece on the girder steel, the square steel tube wall is connected with post jamb by fillet weld, simple structure, easy construction, and girder steel is connected with angle steel by high strength friction bolt, simple structure, easy to connect, by the gauge size of pilot angle steel fastener and the quantity of high-strength bolt, control the moment of flexure ability to bear of node, make node have preferably plastic rotation, under geological process, better dissipation energy is realized the design concept of ductility joint.

Fig. 2 is the top view of the utility model node.
Among the figure: the upper internal partition of 1a-, internal partition under the 1b-, the upper angle iron connecting piece of 2a-, angle iron connecting piece under the 2b-, 3-fillet weld, 4-high strength friction bolt, 5-girder steel, 6-square steel pipe.
The specific embodiment
With reference to the accompanying drawings, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model is at the square steel pipe 6 interior internal partitions that all are welded with corresponding to place, the girder steel 5 upper and lower edge of a wing, that is to say, in the square steel pipe 6 corresponding to place, girder steel 5 top flanges, be welded with internal partition 1a, in the square steel pipe 6 corresponding to 5 places, the lower girder steel edge of a wing, be welded with lower internal partition 1b; Square steel pipe 6 walls at place, girder steel 5 top flanges are welded with angle iron connecting piece 2a, are welded with lower angle iron connecting piece 2b at square steel pipe 6 walls at place, girder steel 5 bottom flanges; Girder steel 5 top flanges are connected on the upper angle iron connecting piece 2a by high strength friction bolt 4, and girder steel 5 bottom flanges are connected on the lower angle iron connecting piece 2b by high strength friction bolt 4.The fillet weld connected mode is all adopted in the welding of the upper angle iron connecting piece 2a shown in the figure and lower angle iron connecting piece 2b and square steel tube wall.
During construction, internal partition 1 and angle iron connecting piece 2 are welded on the square steel pipe wall 6 in advance in factory, and angle iron connecting piece 2 adopts high strength friction-type bolt 4 to be connected with girder steel at building-site.
