Description
Technical field
A kind of steel reinforced concrete superposed beam of the utility model and middle column jointing gusset, belong to building structure field.
Background technology
Concrete folding structure is the overall form of structure of one deck in-situ layer formation that superposes on precast unit, comprises the members such as superposed beam, superposed column, superimposed sheet.Superposed beam, the connection of post node is the pith that structure need to be considered, the stable performance that directly affects structure connecting, connecting the mode realizing affects again the difficulty of site operation, now iterative structure beam column used connects and stretches out reinforcing bar when mostly prefabricated by superposed beam and then become entirety with post reserved steel bar colligation concreting at the scene, complicated operation, technological requirement is high, affect site operation progress, and superposed beam needs single span to make, single span is installed, each all need to be at two ends fabrication and installation and post connection end across beam, increase material and artificial consumption, increase beam and column difficulty of construction in lifting connection procedure.
Utility model content
The purpose of this utility model is to provide a kind of steel reinforced concrete superposed beam and middle column jointing gusset, realize single span superposed beam by the connection of center pillar with simple structure, not only simplify the making of superposed beam termination, save material resources, reduce construction hoisting difficulty, and promote building structure overall performance, increase the resistant function of node to seismic load.
The utility model is achieved through the following technical solutions:
A kind of steel reinforced concrete superposed beam of the utility model and middle column jointing gusset, by steel reinforced concrete superposed beam, precast concrete quadrangle steel pipe center pillar and shaped steel branch sleeve composition, described shaped steel branch sleeve by two blocks of edge of a wing steel plates be vertically connected the quadrangle that two blocks of steel webs therebetween form in casement steel branch sleeve, between the edge of a wing steel plate at these shaped steel branch sleeve two ends and steel web, be symmetrically connected with the junction plate of putting more energy into up and down; Precast concrete quadrangle steel pipe center pillar is arranged between two adjacent beam-ends of steel reinforced concrete superposed beam, and the corresponding suit of shaped steel adapter sleeve jacket casing is affixed outside it; Shaped steel branch sleeve is corresponding affixed with frange plate up and down, the shape steel web of its corresponding end steel reinforced concrete superposed beam shaped steel bone respectively by the junction plate of putting more energy into up and down, the steel web at its two ends; Implement in the lump shaped steel branch sleeve bottom and the precast beam concreting of steel reinforced concrete bottom prefabricated after, again on this prefabricated tie-beam, the concrete cast-in-situ that carries out shaped steel branch sleeve top and steel reinforced concrete top Cast-in-situ Beam, finishing type steel concrete composite girder is connected with the integrative-structure of precast concrete square steel pipe center pillar.
Empty and precast concrete quadrangle steel pipe center pillar adaptation in the quadrangle of described shaped steel branch sleeve.
The shaped steel height adaptation of the spacing of the upper and lower stiffener of described shaped steel branch sleeve and steel reinforced concrete superposed beam.
In the quadrangle of described shaped steel branch sleeve, in the quadrangle steel reinforced concrete center pillar gap of sky and its socket, fill pea gravel concreten.
Described quadrangle steel reinforced concrete center pillar is made up of quadrangle shaped steel tubing string and interior pouring concrete.
Described steel reinforced concrete superposed beam is made up of shaped steel bone, the concrete prefabricated beam of bottom shaped steel bone and top shaped steel bone cast-in-situ concrete beam.
A kind of steel reinforced concrete superposed beam of the utility model column jointing gusset, adopts conformal shaped steel branch sleeve, and makes many single beams realize continued access by center pillar, and its making is more convenient, and structural integrity is better; When every beam lifts in tradition construction, all will control end positions, but use this kind of form to make many beams as long as determine two ends and side column position, beam is connected with center pillar and only needs point of lifting pillars, reduces construction hoisting difficulty; Install at the sleeve that node the uses scene of being prefabricated in the factory, and reduces the operation of site operation, reduces the uncontrollability that field operation too much causes construction quality when the reduction of erection time; Sleeve and beam weld concrete by shaped steel and are wrapped to form the form of being rigidly connected, and two ends welding between sleeve and center pillar, the middle pea gravel concreten of filling connect closely beam and column node, structure transmission force property is good, increases the resistant function of node to seismic load.
