Abstract
The utility model discloses a deformation-resistant jig frame tool for welding a bridge top plate, a bottom plate and a web. The deformation-resistant jig frame tool for welding the bridge top plate, the bottom plate and the web comprises a tool body composed of a top beam, a top girder and a jig frame supporting frame, a deformation-resistant arc formwork is arranged on the inner side wall of the top beam in the horizontal direction, a workpiece to be welded is arranged on the deformation-resistant arc formwork, and a workpiece body is further provided with power pressing devices acting on the two ends of the workpiece to be welded. According to the deformation-resistant jig frame tool, welding deformation is effectively controlled, automatic ship-type welding of the structure is achieved, the production efficiency is improved, the welding quality of a product is improved, and the labor intensity is relieved.
Description
Technical field
The utility model relates to building field, relates in particular to a kind of bridge top board, base plate and web welding anti-distortion jig frame tooling.
Background technology
At present, steel construction is widely used in science of bridge building, architectural engineering, decorative engineering.And the main member of steel structure bridge is welding roof and floor module unit, vertical and horizontal diaphragm, tuyere and connecting box.All there is welding deformation problem in these members, if welding deformation is not corrected, not only affect bridge structure integral installation quality and duration in manufacturing process, also can reduce the security reliability of science of bridge building.When welded bridge steel construction produces distortion, should take various effective measures to prevent or reduce distortion, in the time that deflection exceedes current specifications regulation, should manage to correct, it being reached and meet product quality requirement.Fact proved, the bridge member of most distortion can be corrected.The method of correcting is all to manage to cause new distortion to reach the distortion that counteracting has occurred, and is commonly called as reversible deformation.The antidote of generally applying in actual production process, mainly contains: mechanical rectification, flame straightening and comprehensive correction.Machinery is corrected as the term suggests be exactly to utilize mechanism to make member produce reversal deformation to eliminate welding deformation; Flame straightening is that the Zone Heating For Metal at the relative position of welding deformation is arrived to hot state, utilizes the distortion that non-uniform heat flux causes to correct the distortion that Welding Structure has been produced, instrument and equipment that the method only needs common gas welding to use.But flame straightening is the experimental technical work of a more difficult operation, method is grasped, temperature control is improper also can cause the more large deformation that member is new.Therefore, flame straightening will have abundant practical experience.And comprehensive correction to be machinery correct with the combination of flame straightening in actual production the most frequently used to be comprehensive correction method.Do a general analysis for kind, the antidote of bridge steel structure welding deformation herein.The main member of bridge steel structure is welding roof and floor module unit, vertical and horizontal diaphragm, tuyere and connecting box.Welding deformation often adopts following three kinds of flame straightening methods: wire heating, point-like heating and triangular heat method.Three kinds of above-mentioned heatings are cumbersome, and cost is higher, and correcting process cannot manual control, increased a lot of troubles to the installation of current steel construction.
summary of the invention
The deficiency existing for prior art, technical problem to be solved in the utility model is, provide a kind of simple in structure, effectively control welding deformation, realize automatic ship type welding, enhance productivity, improve the welding quality of product, reduce bridge top board, base plate and the web welding anti-distortion jig frame tooling of labour intensity.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of bridge top board, base plate and web welding anti-distortion jig frame tooling, comprise the frock body being formed by top cross beam, top longeron and moulding bed bracing frame, described top cross beam madial wall along continuous straight runs is provided with reversible deformation radian template, workpiece to be welded is located in reversible deformation radian template, is also provided with the power hold down gag that acts on workpiece to be welded two ends on frock body.
Above-mentioned bridge top board, base plate and web welding anti-distortion jig frame tooling, described power hold down gag is jack.
Above-mentioned bridge top board, base plate and web welding anti-distortion jig frame tooling, described top cross beam, top longeron and moulding bed bracing frame all adopt H200 I-steel composition.
Above-mentioned bridge top board, base plate and web welding anti-distortion jig frame tooling, described moulding bed bracing frame top is provided with the second cross beam be arrangeding in parallel with described top cross beam, and jack is located on second cross beam.
The advantage of the utility model bridge top board, base plate and web welding anti-distortion jig frame tooling is: effectively control welding deformation, realize the automatic ship type welding of this kind of structure, improved production efficiency, improve the welding quality of product, reduced labour intensity.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details;
As shown in Figure 1, 2, a kind of bridge top board, base plate and web welding anti-distortion jig frame tooling, comprise the frock body being formed by top cross beam 1, top longeron 2 and moulding bed bracing frame 3, this frock body fixes on the ground by expansion bolt 9, the madial wall along continuous straight runs of described top cross beam 1 is provided with reversible deformation radian template 4, workpiece 5 to be welded is located in reversible deformation radian template 4, is also provided with the power hold down gag at the two ends that act on workpiece 5 to be welded on frock body.Power hold down gag is jack 6, and according to the different length of bridge top board or base plate, jack 6 can be selected 15~20T specification as required.Top cross beam 1, top longeron 2 and moulding bed bracing frame 3 all adopt H200 I-steel composition.The top of described moulding bed bracing frame 3 is provided with the second cross beam 7 be arrangeding in parallel with described top cross beam 1, and jack 6 is located on second cross beam 7.
Using method: the bridge top board assembling or base plate are placed on framework, determine reversible deformation radian template 4 according to the size of workpiece 5 to be welded, then reach suitable anti-deformation with the both sides that jack 6 is pressed in workpiece 5 to be welded.Adjusting device angle to 45 °, then automatic welding, is welded on workpiece to be welded 5 surfaces by floor 8, certainly, for protecting the surface of workpiece 5 to be welded to prevent from being damaged by pressure by jack 6, can between jack 6 and workpiece to be welded 5, backing plate be set.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, variation, remodeling, interpolation or the replacement made, all should belong to protection scope of the present invention.
