Abstract
The invention relates to a groove steel-concrete integration beam, belonging to the bridge support element area, which can be used in track bridge; railway bridge; and road Bridge. The invention comprises a steel box beam whose top is open, concrete filled in the inner side of steel box beam and the anti-cutting connection element welded on the inner side of steel box beam. wherein, said open steel box beam is formed by a bottom plate and a middle plate, whose sections are in U or W shape; the anti-cutting connection element can integrate the steel beam and the concrete as a whole to display the anti-compression property of concrete; the steel plate can resist the pulling stress of each direction and avoid surface breakage; and the anti-cutting connection element can transfer the shearing force between steel box beam and concrete and avoid their separation. The invention has the advantages of simple operation, application of avoiding surface breakage and wider application prospect, as well as the advantages of initial stress concrete groove beam.
Description
Technical field
The present invention relates to a kind of grooved steel-concrete combination beam that can be applicable to city rail bridge, railroad bridge and highway bridge.Belong to the bridge construction technical field.
Background technology
Traditional city rail elevated bridge generally adopts deck type box-type section or T type cross section, and the building integral height is big.Not only bigger to the civic landscape influence, the dough figurine group causes sense of depression over the ground, and easily near resident is produced noise jamming.Trough girder is a kind of form of structure that functions such as carrying, noise reduction and operation system are organically combined, and can reach the purpose that reduces structure height and reduce vision, noise pollution simultaneously.With respect to the deck type beam bridge, the trough girder in U type cross section can utilize bearing plate track and train, reduces track absolute altitude and integral bridge height, reduces the influence to surrounding enviroment; But girder is the double as noise barrier simultaneously, has saved sound insulating panel, helps reducing pollution from environmental noise; U type beam inboard is easy to arrange equipment such as communication, electric power, the space availability ratio height in whole cross section; The top flange can be used as access path and passenger's emergency evacuation passage or uses as the part of platform; Defencive function when having derail.Existing trough girder all adopts the prestressed reinforced concrete scheme, is subjected to the restriction of prestressed concrete own characteristic, and the particularly too complicated construction technology and the reduction of durability afterwards that is easy to ftracture and ftracture bring a lot of difficulties for the application of trough girder.
Summary of the invention
The purpose of this invention is to provide a kind of grooved steel-concrete combination beam that can significantly improve structural bearing capacity, rigidity, cracking resistance and workability.
Technical scheme of the present invention is as follows:
A kind of grooved steel-concrete combination beam is characterized in that: this compound beam is by open-topped steel case beam, is cast in the steel concrete of steel case beam inboard and the shear connector that is welding on the steel case beam inboard constitutes; Described opening steel case beam is made up of base plate and web, and its section adopts U type or W type.
Technical characterictic of the present invention also is: the upper end of described web is provided with top board, concreting on the top board.Described shear connector adopts peg.
The present invention has the following advantages with respect to prior art and the high-lighting effect: the present invention is combined by grooved girder steel and concrete two parts, and steel work is a produce in factory partly, is easy to ensure the quality of products; Concrete directly utilizes steel plate to carry out cast in situs, and non-mould construction also is easy to control quality; Steel work part weight is lighter, brings convenience to installation in position; Structure tensile region encased steel plate has been avoided concrete cracking, and is convenient to safeguard good endurance; Structure construction is simple, and the girder steel base plate all can be given full play to tensile strength horizontal and vertical, with respect to prestressed reinforced concrete construction simplified construction greatly, avoids the difficulty of reinforcing bar binding, welding and prestressing force two directions tension; Bearing and joint construction are simple, by bolt or welding, can form multi-joint structure easily, thereby can further strengthen the rigidity of structure and improve the comfortableness of driving.

Fig. 2 is the schematic cross-section of U type cross section two-rail grooved compound beam.
Fig. 3 is the schematic cross-section of W type cross section two-rail grooved compound beam.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
The invention provides the grooved steel-concrete combination beam that can significantly improve structural bearing capacity, rigidity, cracking resistance and workability.In Fig. 1, Fig. 2 and grooved steel-concrete combination beam structural representation shown in Figure 3, melting welding shear connector 3 on prefabricated profiled upper opening steel case beam.At the medial surface concreting 2 of steel case beam, and be combined into one with steel case beam.Dispose the steel bar stress and the distributing bar of some in the concrete 2.
Working procedure of the present invention is:
Grooved steel-concrete combination beam of the present invention is made up of steel work and back pouring concrete two parts, and the two is combined into whole co-operation by the shear connector 3 of melting welding on steel plate.Steel case beam is made up of base plate 4 and web 5, and its section form is determined according to instructions for use, can be U type or W type, and steel plate thickness calculates definite according to beam span and beam width.For striding the less situation in footpath, web 5 should occupy the total height.For striding the bigger situation in footpath,, can be provided with top board 6 in web 5 upper ends for improving the bearing capacity and the rigidity of combined beam structure.Concrete 2 planted agents are provided with reinforcing bar as required, are used to improve the shear-carrying capacity of shear connector, participate in whole stressed to improve the bearing capacity of combined beam structure simultaneously.The thickness of concrete 2 is 100～300mm.Shear connector 3 generally should adopt peg, needs melting welding in base plate 4, web 5 and top board 6 a concrete side to be arranged, peg diameter 16～22mm, and height 80～220mm, spacing 100～250mm can adopt rectangular mesh shape or plum blossom shape to arrange.
Claims (3)
1. grooved steel-concrete combination beam is characterized in that: this compound beam is by open-topped steel case beam, is cast in the steel concrete (2) of steel case beam inboard and the shear connector (3) that is welding on the steel case beam inboard constitutes; Described opening steel case beam is made up of base plate (4) and web (5), and its section adopts U type or W type.
