Technical field
The present invention relates to Steel Bridge splicing structure field more particularly to a kind of Steel Truss Beam top booms and lower boom assembly to use
Moulding bed and splicing structure.
Background technique
Being assembled on moulding bed on general Steel Truss Beam carries out assembled, and general jig structure is according to the shape of truss two
The sub-truss girder construction by the way of supporting block causes a riveted holes and welding position to be blocked the welding in inconvenient later period
Assembling；Furthermore it is directed to general linear Steel Truss Beam, the side of support frame and Steel Truss Beam on support baseboard may deposit
Being easy to cause Steel Truss Beam in the problem of out of plumb in laying is that there is a phenomenon where discontinuity；Furthermore general steel truss
It is assemblied into linear structure, the splicing structure of broken line type needs the position of camber to be connected with joining section in bridge floor
It connects, it is therefore desirable to which a kind of Steel Truss Beam structure of bending-type realizes assembled welding.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Steel Truss Beam top booms and lower boom assembly moulding bed and spelling
Assembling structure can also can solve the steel truss for needing camber while solving the assembly of girder frame structure of novel broken line type and asking
Structure of setting a roof beam in place realizes that the welding of pre- joining section meets the requirement of camber.
In order to solve the above technical problems, the technical solution of the present invention is as follows: a kind of Steel Truss Beam top boom and lower boom are assembled
With moulding bed and splicing structure, innovative point is: including jig structure and girder frame structure；The jig structure and girder truss knot
Structure, which is arranged on moulding bed, carries out assembly；
The jig structure includes support baseboard and support frame；The support baseboard is horizontally disposed, and the one of the support baseboard is flat
The side profile structure for having girder frame structure is delineated on face；Support frame as described above is in door type structure along the girder truss on support baseboard
Side profile carry out contour laying, support frame as described above is connected on support baseboard by anchoring piece；
The girder frame structure includes top boom, lower boom and connection web member；The top boom and lower boom are broken line type structure
And top boom and lower boom form camber；The top boom is successively weldingly connected including at least four chord member segments and top boom
Outside splice the bottom board unit that has；The lower boom includes at least four chord member segments and is successively weldingly connected and is located at both ends
In the angle structure less than 180 ° between two chord members and remaining chord member segment；It is provided with and connects on the top boom and lower boom
The ox leg structure of web member cooperation is connect, and is provided with stiffening plate in ox leg structure；The inclined alternately shape of the connection web member is connected to
On the ox leg structure of top boom and lower boom.
Further, the extending direction of bottom board unit is provided with spaced set in the bottom board unit has several U
Rib；Vertical U rib and bottom board unit are provided with several stiffener plate structures on the U rib.
Further, support frame as described above on support baseboard the side of spaced set and support frame perpendicular to being attached thereto
The profile scribing line of girder frame structure on the support baseboard connect.
Further, using molten between the ox leg structure of the ox leg structure and lower boom of the connection web member and top boom
Welding thoroughly.
The present invention has the advantages that
1) girder truss of broken line type is met in the present invention by using the assembled moulding bed of the girder frame structure of dedicated broken line type
The when low strength formwork of structure and the requirement of stability avoid sheltering from welding position in assembly, and structure is simpler and stability
It is higher；Furthermore the Application in Pre-camber of girder truss can be achieved in the girder frame structure of broken line type after assembly, convenient for the embedding benefit with bridge floor
Segmental structure is installed, so that installation effectiveness is higher while also meeting camber requirement required for bridge.
