Abstract
The utility model relates to an overtuning jig for controlling welding deformation of a slab unit of a steel box, which comprises a vertical column, a bottom board and a plurality of height adjustment blocks. The vertical column is connected to the bottom side of the bottom board. The height regulation blocks, fixedly connected to the upper side of the bottom board, are ordered in array, wherein height regulation blocks in the same column have the same height, while height regulation blocks in the same row has height reduced from the middle to both sides. A restraint fastening board is provided on both sides of the bottom board. During the process of welding the slab unit of the steel box, ribs on the back of the top board is welded to the top end of the height regulation blocks, making ribs on the top board connected integrally in order to increase anti-bending rigidity of the top board, then a u-shaped rib is welded onto the front side of the top board. By presetting the ordering height of the height regulation blocks, a predetermined anti-deformation amount is generated for the top board to offset the deformation caused by welding.
Description
Technical field:
The utility model relates to building field, relates in particular to steel case beam, the particularly Welding Structure of steel case beam, and 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 purpose of this utility model is to provide a kind of upset moulding bed of controlling the distortion of steel case beam slab element solder, and 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 utility model 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 utility model 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 adopt upset moulding bed of the present utility model, 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 is 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 utility model and prior art are compared, and its effect is actively with tangible.The utility model 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 the structural representation of the upset moulding bed of control steel case beam slab element solder distortion of the present utility model.
Fig. 2 is the schematic diagram of the steel case beam among the embodiment of upset moulding bed of control steel case beam slab element solder of the present utility model distortion.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, the upset moulding bed of control steel case beam slab element solder distortion of the present utility model, 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.
