Abstract
The utility model relates to a prestressed concrete beam and concrete-filled steel tube column joint structure which comprises a joint area formed by connecting a prestressed concrete beam and a concrete-filled steel tube column, open holes are formed in the tube wall of the concrete-filled steel tube column of the joint area, and prestressed steel strands adhere through a post-tensioned method and penetrate through the open holes to be communicated with the joint area of the prestressed concrete beam and the concrete-filled steel tube column. According to the joint structure, it can be guaranteed that the connecting position between the large-span prestressed concrete beam and the concrete-filled steel tube column reliably transmits shearing force and bending moment, and bending resistant and compression resistant bearing capacity of the concrete-filled steel tube column is not weakened. Compared with a steel reinforced concrete beam or a steel beam scheme, the usage amount of steel is small, and economy is good. The prestressed concrete beam and concrete-filled steel tube column joint structure can be widely applied to structural engineering such as a railway station elevated station building and a conference and exhibition center, wherein the structural engineering is large in span and load and has strict requirements for a building effect, a sectional size of a component and economy.
Description
Technical field
The utility model belongs to building structure field, is specifically related to apply prestressed one in a kind of reinforced concrete beam and Frame Joints of Concrete-Filled Steel Tube and constructs.Be particularly useful for the spans such as the overhead station of Railway Passenger Stations, conference and exhibition center and load larger, and architectural effect, sectional dimension of members and economy all had to the Structural Engineering of strict demand.
Technical background
Owing to there being good collaborative work characteristic between steel pipe and concrete, steel pipe can operative constraint concrete axial deformation, concrete can effectively be avoided the inside cripling of steel pipe, meet modern architecture construction and industrialized requirement, thereby concrete filled steel tube is widely applied.For load and span, all compared with for large structure, the economy of prestressed concrete beam is better than girder steel and girder with rolled steel section en cased in concrete, just, owing to not have to solve and the joint structure problem of steel core concrete column, so just make to apply, is subject to certain limitation.The utility model is by integrated use series of measures, saving under the prerequisite of material and convenient construction, solved that post steel pipe holes reinforced, beam column node area shear-carrying capacity improve, the reinforcing bar of concrete beam is in problems such as node area connections, and the advantage of prestressed concrete beam and steel core concrete column can be given full play to.
Summary of the invention
The purpose of this utility model is to provide a kind of prestressed concrete beam and Frame Joints of Concrete-Filled Steel Tube structure, this node can be in the case of reducing the shear strain of member, permanent set and crack width, guarantee connecting place reliable delivery shearing and moment of flexure, bending resistance, the Compressive Bearing Capacity of steel core concrete column do not reduce., compare with girder steel scheme with girder with rolled steel section en cased in concrete meanwhile, can save material, convenient construction.
The utility model adopts following technical scheme: a kind of prestressed concrete beam and Frame Joints of Concrete-Filled Steel Tube structure, comprise the node area being connected to form by prestressed concrete beam and steel core concrete column, tube wall at the steel core concrete column of node area is provided with perforate, and post stretching bonded prestress steel strand connect beam column node area through perforate.
The utility model is at the other perpendicular rib in top that is provided with of perforate, and the steel pipe that perforate is weakened carries out reinforcement, guarantees that bending resistance, the Compressive Bearing Capacity of steel core concrete column do not reduce.
In above-mentioned prestressed concrete beam, be provided with vertical muscle, the outer ring plate that node area is provided with internal partition and welds with the vertical muscle in prestressed concrete beam.By vertical muscle in outer ring plate and reinforced concrete beam, weld to transmit beam-ends moment of flexure.
On the outer wall of steel pipe of above-mentioned steel core concrete column, be welded with peg and horizontal annular reinforcing bar.
Above-mentioned peg and horizontal annular reinforcing bar are multiple, and peg and horizontal annular spacing of reinforcement layout.To strengthen the globality of prestressed concrete beam and steel core concrete column, strengthen shear resistance.
The utility model can arrange the perpendicular rib in bottom at the downside of outer ring plate.
The utility model also can arrange cap in described beam column node area, cap and peg, is welded in the steel corbel acting in conjunction that the perpendicular rib of horizontal annular reinforcing bar on post outer wall of steel pipe and outer ring plate and bottom forms, and Shear force within the beam end is reliably reached to steel core concrete column.
The superiority of the utility model technology is: this node structure can not only reduce shear strain, permanent set and the crack width of member, improve the rigidity of member, can also guarantee large-span prestressed concrete beam and steel core concrete column connecting place reliable delivery shearing and moment of flexure, bending resistance, the Compressive Bearing Capacity of steel core concrete column do not reduce, the design principles of final realization " strong node, weak member ".Meanwhile, with respect to girder with rolled steel section en cased in concrete or girder steel scheme, steel using amount is low, good economy performance.
