Abstract
The combined profiled plate-concrete bridge includes steel beam, shear key, profiled steel plate, post-cast concrete layer and reinforcing net. The combined profiled plate-concrete bridge features the profiled steel plate in the top opening of the steel beam welded to the steel beam top board or penetrated with the share key, the reinforcing net in the top for depositing concrete layer, and the share key in the top of the steel beam to connect the post-cast concrete layer and the steel beam integrally. Compared with laminated plate combining beam, the present invention has the advantages of improved integrality of the post-cast concrete layer, less dead weight, simple structure, convenient construction, etc. and has wide application in bridge construction and building industry.
Description
Technical field the present invention relates to a kind of profiled sheet steel-concrete combined bridge, more particularly, relates to a kind of highway, railway, isostructural steel-concrete combination beam that need not template of Urban Bridge of being particularly suitable for.
Background technology in the prior art, the relevant report of existing profiled sheet combination floor, disclosed 88104198.X " in reinforced concrete frame structure, using the method for profiled sheet combination floor ", because that it bears is uniform pedestrian load, compare with the huge wheel load load of highway, railroad bridge, inequality in the design.The present invention can save and touch timbering by the application of profiled sheet in the bridge field, effectively prevents concrete cracking, and good looking appearance is increased economic efficiency.
Summary of the invention the objective of the invention is to utilize the plate effect of touching of profiled sheet, saves and touches timbering, effectively prevents concrete cracking, good looking appearance.Compare with folding plate combined beam, great advantage is that back pouring concrete deck globality is better, can be lighter and handier, alleviate deadweight; Have advantages such as simple in structure, easy construction, be with a wide range of applications in building trade especially bridge construction.
In order to achieve the above object, the invention provides following technical scheme: design a kind of profiled sheet steel-concrete combined bridge, comprise girder steel (1), its end face has shear connector (2), arranges profiled sheet (3) at girder steel end face opening part, the edge of profiled sheet (3) and the welding of girder steel top board, perhaps penetrate by shear connector (2), arrange steel mesh reinforcement (5) at girder steel, profiled sheet end face, concreting layer (4) is linked to be integral body by shear connector (2) with layer of concrete (4) and girder steel (1).
The present invention is in work progress, earlier girder steel (1) is set up, lay profiled sheet (3) at girder steel (1) end face opening part, at girder steel (1) the end face shear connector (2) of burn-oning, go up laying steel mesh reinforcement (5) at girder steel (1) and profiled sheet (3) then, last pouring concrete layer (3) after layer of concrete (3) fully condenses, promptly forms profiled sheet steel-concrete combined bridge.
The present invention's technical scheme preferably is: girder steel (1) is steel I-beam or box steel beam, and the upper limb concrete bears compressive stress, and the lower edge girder steel bears tensile stress, gives full play to mechanical properties of materials.
Compared with prior art, the pedestrian load is more even for profiled sheet combination floor, and load is less.The present invention is used in profiled sheet under the huge wheel load load of highway, railroad bridge, can satisfy the part and the stressed needs of overall structure of bridge deck, designs a kind of profiled sheet combined bridge of simple in structure, easy construction.That designed compound beam has is simple in structure, easy construction, saving are touched timbering, effectively prevented advantages such as concrete cracking, good looking appearance, increases economic efficiency, and is with a wide range of applications in the bridge construction field.
Be description of drawings of the present invention below the description of drawings:
Fig. 1 is the cross-sectional structure schematic diagram of I-shaped steel-concrete profiled sheet compound beam;
Fig. 2 is the cross-sectional structure schematic diagram of box-shaped steel-concrete profiled sheet compound beam;
Fig. 3 is the cross-sectional structure schematic diagram of triangle steel pipe concrete profiled sheet compound beam;
Among Fig. 1～Fig. 3, the 1st, girder steel, the 2nd, shear connector, the 3rd, profiled sheet, the 4th, layer of concrete, the 5th, steel mesh reinforcement.
By specific embodiment the present invention is carried out more detailed description below the specific embodiment:
With reference to Fig. 1～3, earlier girder steel (1) is erected on the Bridge Pier, lay profiled sheet (3) and make it and girder steel (1) spot welding at girder steel (1) end face opening part, at girder steel (1) end face with the welding machine shear connector (2) of burn-oning, go up laying steel mesh reinforcement (5) at girder steel (1) and profiled sheet (3) then, last pouring concrete layer (3) is after layer of concrete (3) fully condenses, promptly form profiled sheet steel-concrete combined bridge, whole process is without any need for template.
Claims (5)
