Abstract

The utility model discloses an assembly jig frame of plate blocks of a steel-truss-beam flexible-arch orthotropic bridge deck. The assembly jig frame comprises a left longitudinal beam, a right longitudinal beam, steel vertical columns and a cross-beam bottom plate, wherein the longitudinal beams adopt a reinforced concrete structure; embedding plates are arranged on the longitudinal beams according to the spacing of cross beams; the steel vertical columns are fixedly arranged on all the embedding plates; cross-beam positioning gusset plates are respectively arranged on all the steel vertical columns; and the cross-beam bottom plate is fixedly connected among the cross-beam positioning gusset plates of the steel vertical columns at the corresponding positions of the left longitudinal beam and the right longitudinal beam. The assembly jig frame disclosed by the utility model has the advantages that the manufacture and the installation are unified in reference, so that the overall size and the positioning accuracy of the bridge plate blocks are ensured.

Description

The assembly unit moulding bed of steel truss girder sliding roadway arch cross bridge floor board plate
Technical field
The utility model relates to a kind of assembly unit moulding bed of steel truss girder sliding roadway arch cross bridge floor board plate, is specially adapted to the upright method of hull section construction assembly unit of the compound bridge deck of steel truss girder orthotropic stainless steel, belongs to bridge steel structure manufacturing technology field.
Background technology
The steel truss girder cross bridge floor board is made up of crossbeam, T type longeron, U type rib, rib of slab, plate unit five parts, and crossbeam and main truss are bolt, and longitudinal stiffener (T type longeron, U type rib, rib of slab) is a bolt, and the plate unit is for being welded to connect.The steel truss girder cross bridge floor board generally adopts on-the-spot whole section assembling or the assembly unit of loose mail bridge location.In view of the restriction in stainless steel clad plate processing length and on-site consolidation place, whole section assembling is difficult to realize; The assembly unit of loose mail bridge location, bridge location welding engineering amount is big, and welding deformation is difficult to control, and welding residual stress is concentrated.Above-mentioned two kinds of methods are not suitable for the assembly unit of orthotropic stainless steel bridge deck, and construction quality also is difficult to obtain assurance.So must carry out piecemeal by pair of orthogonal opposite sex stainless steel bridge deck, carry out the batch production processing and manufacturing.For guaranteeing the accuracy of manufacture and the welding quality of bridge floor plate, guarantee bridge deck and bridge location installation forming state consistency, the bridge deck manufacturing must be carried out on special-purpose assembly unit moulding bed.
The utility model content
The purpose of the utility model provides the compound bridge deck upright method of hull section construction of a kind of steel truss girder orthotropic stainless steel assembly unit moulding bed; Promptly utilize the scene of upright method of hull section construction assembly unit moulding bed simulation bridge deck to become the bridge state, accomplish the control of appearance and size, position, hole precision and the welding quality of bridge deck.
The utility model technical solution problem provides following scheme:
A kind of assembly unit moulding bed of steel truss girder sliding roadway arch cross bridge floor board plate; Two longerons, steel post, crossbeam base plate about comprising; It is characterized in that: said longeron adopts reinforced concrete structure, according to the crossbeam spacing embedded board is set on the said longeron, is installed with steel post on said each embedded board; Said each steel post is attend branch crossbeam location node plate is installed, and is fixedly connected the crossbeam base plate between the crossbeam location node plate of the steel post of said left-right longeron relative position.
The below of said crossbeam base plate is provided with buttress, and said buttress top is provided with jack.
The moulding bed of the compound bridge deck assembly unit of steel truss girder orthotropic stainless steel is confirmed according to the appearance and size of " 3+1 " internode assembling method.Upright method of hull section construction assembly unit moulding bed is made up of longeron, steel post, buttress and crossbeam location node plate etc.For guaranteeing the keyhole positioning accuracy and simplify construction technology that crossbeam location node plate directly is connected with cantilever diaphragm and base plate keyhole, has cancelled the junction plate locate mode of conventional cantilever diaphragm and base plate, has improved positioning accuracy and has made work efficiency.The welding contracted quantity of the vertical butt joint of preformed plate unit bridge location (general 2~3mm can adjust according to actual conditions) during the drilling of crossbeam location node plate.For the compound bridge deck welding deformation of control stainless steel, play the head piece base plate through buttress, make it to produce the welding anti-distortion amount, to guarantee the dimensional accuracy after the bridge deck block welding is accomplished.
Advantage of the present invention is:
1, the upright method of hull section construction assembly unit moulding bed of the compound bridge deck of orthotropic stainless steel becomes the bridge state consistency with bridge deck, makes and the reference for installation unification, has guaranteed appearance and size, the positioning accuracy of bridge floor plate.
2, before the bridge deck block welding, be convenient to utilize upright method of hull section construction assembly unit moulding bed to apply reversible deformation, can effectively control welding deformation.
3, utilize upright method of hull section construction assembly unit moulding bed, the mode of depression is carried out the compound bridge deck welding deformation rectification of stainless steel in the employing, guarantees the planeness of the compound bridge deck of stainless steel.
4, the crossbeam location node plate of upright method of hull section construction moulding bed and the direct keyhole of cantilever diaphragm are located by connecting, and have replaced common locate mode with the scab transition, have improved size Control precision and work efficiency.
5, the upright method of hull section construction moulding bed is convenient to check repetition measurement, helps guaranteeing the compound bridge deck appearance and size of orthotropic stainless steel, position, hole precision and welding quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing; A kind of assembly unit moulding bed of steel truss girder sliding roadway arch cross bridge floor board plate, two longerons 1,2, steel post 3, crossbeam base plate 4 about comprising, said longeron 1,2 adopts reinforced concrete structures; Spacing according to crossbeam base plate 4 on the said longeron 1,2 is provided with embedded board; Be installed with steel post 3 on said each embedded board, said each steel post 3 is attend branch crossbeam location node plate 5 is installed, and is fixedly connected crossbeam base plate 4 between the crossbeam location node plate 5 of the steel post 3 of said left-right longeron 1,2 relative positions; The below of said crossbeam base plate 4 is provided with buttress 6, and said buttress 6 tops are provided with jack 7.
