Abstract
The invention discloses an overturning jig frame for controlling the welding deformation of a steel box girder plate unit, which consists of an upright post, a bottom plate and a plurality of height regulation blocks, wherein the upright post is connected to the lower side of the bottom plate; the height regulation blocks are fixedly connected to the upper side of the bottom plate, and are arranged in a matrix; the heights of the height regulation blocks in the same column are equal, while the heights of the height regulation blocks in the same row are sequentially decreased from a middle part to two ends; and the two sides of the bottom plate are provided with a restraint clamping plate respectively. In the welding process of the steel box girder plate unit, lath ribs on the back side of a top plate are welded and fixed with the top ends of the height regulation blocks to be connected into a whole, so that the bending rigidity of the top plate is increased; and then a U-shaped ribbed plate is welded in front of the top plate. The arrangement heights of the height regulation blocks are preset, and a preset reverse deformation is produced for the top plate, so that deformation caused by welding is counteracted.
Description
Technical field:
The present invention relates to building field, relate in particular to steel case beam, the particularly Welding Structure of steel case beam, concrete is a kind of upset moulding bed of controlling the distortion of steel case beam slab element solder.
Background technology:
In the Longspan Bridge, steel case beam is because workmanship is stable, span is big, set up convenient and often be used.The manufacturing of steel case beam is owing to many-sided reasons such as material specification, transportation, on-the-spot installation, the mode that generally adopts factory, building site to combine.Steel case beam comprises a plurality of casees chamber, be spliced to form by the plate unit, constitute by top board and the welding of U-shaped floor, the top board dorsal part is provided with horizontal ribs, because steel case back plate unit primary structure form is the orthotropic plate structure, is subjected to welding heat affected, panel Welding Angular Deformation amount is up to 40mm, the accuracy of manufacture of the plate unit that exerts an influence of welding deformation if make it reach the flatness requirement by flame straightening, then need increase considerable workload.
Summary of the invention:
The object of the present invention is to provide a kind of upset moulding bed of controlling the distortion of steel case beam slab element solder, the upset moulding bed of described this control steel case beam slab element solder distortion will solve the technical problem of steel case beam sweating heat distortion in the prior art.
The upset moulding bed of this control steel case beam slab element solder distortion of the present invention is made of column, base plate and a plurality of height regulating block, wherein, described column is connected the downside of described base plate, described height regulating block is fixedly connected on the upside of base plate, the height regulating block is matrix and arranges, the height of the height regulating block in the same row equates that all the height of the height regulating block among the same row reduces to two ends successively from the middle part.
Further, in same row's height regulating block, the height of middle part height regulating block is 234mm, and the height of two ends height regulating block is 100mm.
Further, the both sides of described base plate are provided with the constraint clamp.
Operation principle of the present invention is: in steel case beam slab element solder process, earlier that the lath rib of top board dorsal part is fixing with the top welding of height regulating block, make top board top bars rib be linked as integral body, to increase the bending rigidity of top board, then at top board front welding U-shaped floor.Arrangement height by the preset height regulating block produces a default anti-deformation to top board, offsets the distortion that brings because of welding with this.Specifically can determine deflection by the actual measurement to the postwelding deformation data, counter plate applies suitable reversible deformation before welding, the angular deformation that produces in welding with basic elimination plate unit.
When carrying out the welding of top board and U type floor, for the fusion penetration that makes weld seam reaches designing requirement, and be convenient to construction during welding operation, the general Type of Welding that adopts is flat fillet weld, and adopts upset moulding bed of the present invention, just can make the fusion penetration of weld seam reach designing requirement, its operation principle is after all welding is finished with the side U type floor on the top board earlier, moulding bed to be rotated to the opposite side angle, so just can make the U type floor of opposite side and the weld seam angle of top board be 45 ° equally, welding operation is convenient a lot.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention utilizes base plate and the height regulating block array that is arranged on the base plate, apply a default anti-deformation to top board, offset the distortion that brings because of welding with this, can reduce the deflection after top board welds greatly, deflection is decreased to 6mm from 40mm of the prior art.
Description of drawings:
Fig. 1 is a kind of structural representation of controlling the upset moulding bed of steel case beam slab element solder distortion of the present invention.
Fig. 2 is the schematic diagram of the steel case beam among the embodiment of a kind of upset moulding bed of controlling steel case beam slab element solder distortion of the present invention.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, a kind of upset moulding bed of controlling the distortion of steel case beam slab element solder of the present invention, constitute by column 4, base plate 5 and a plurality of height regulating block 6, wherein, described column 4 is connected the downside of described base plate 5, and described height regulating block 6 is fixedly connected on the upside of base plate 5, and height regulating block 6 is matrix and arranges, the height of the height regulating block 6 in the same row equates that all the height of the height regulating block 6 among the same row reduces to two ends successively from the middle part.
Only represented to be positioned at same row's height regulating block 6 among Fig. 1.
Further, in same row's height regulating block 6, the height of middle part height regulating block 6 is 234mm, and the height of two ends height regulating block 6 is 100mm.
Further, the both sides of described base plate 5 are provided with constraint clamp (not drawing among the figure).With clamp top board 1 and base plate 5 are blocked earlier before the welding, increase the rigid constraint of top board 1, the generation of restriction top board 1 distortion.Reduce worker's amount of correcting, guarantee the accuracy of physical dimension.
The course of work of present embodiment is: in steel case beam slab element solder process, earlier that the lath rib 3 of top board 1 dorsal part is fixing with the top welding of height regulating block 6, make top board 1 top bars rib 3 be linked as integral body, to increase the bending rigidity of top board 1, then at top board 1 front welding U-shaped floor 2.By the arrangement height of preset height regulating block 6, produce a default anti-deformation for top board 1, offset the distortion that brings because of welding with this.Specifically can determine deflection by the actual measurement to the postwelding deformation data, counter plate applies suitable reversible deformation before welding, the angular deformation that produces in welding with basic elimination plate unit.
