Abstract
The invention relates to a method for manufacturing a thick plate ultra narrow flange H-beam. The method comprises the following steps of: step I, adopting a steel plate to be a manufacturing platform, and intermittently welding a base plate for supporting a web of the thick plate ultra narrow flange H-beam onto the steel plate platform; step II, putting the combined and formed thick plate ultra narrow flange H-beam onto the steel plate platform of the step I; step III, welding fixed blocks on two sides of a flange of the thick plate ultra narrow flange H-beam, and welding a fixed block in a length direction of the H-beam at a certain interval; step IV, embedding a steel wedge between the flange of the thick plate ultra narrow flange H-beam and each fixed block; and step V, adopting a U-shaped fixture to gradually restrain the welding deformation of the thick plate ultra narrow flange H-beam in the length direction. According to the method, the thick plate ultra narrow flange H-beam can be prevented from generating welding deformation in a welding process, the follow-up correction operation is avoided, the production efficiency is effectively improved, and the cost is reduced.
Description
Technical field
The present invention relates to the preparation method of the ultra narrow edge of a wing of a kind of slab H shaped steel.Belong to steel construction processing and fabricating technical field.
Background technology
In the structural steelwork, it is thicker to run into plate through regular meeting, and the H Steel section member that the edge of a wing is very narrow is applied to the core tube of high-rise building rigid steel pile usually.This type H Steel section member is easy to produce phenomenons such as welding deformation, whole distortion owing to thickness of slab, the edge of a wing are narrow in welding process.And in case whole torsional deformation seeing that have the limitation of correcting device now, will be difficult to carry out integral correction.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the preparation method of the ultra narrow edge of a wing of a kind of slab H shaped steel is provided, guaranteeing that the manufacturing process welding does not produce under the situation of welding deformation, improve the make efficiency and making precision of this type member.
The objective of the invention is to realize like this: the preparation method of the ultra narrow edge of a wing of a kind of slab H shaped steel, said method comprises the steps:
Step 2 places the ultra narrow edge of a wing of the slab behind assembled formation H shaped steel on the plate platform of step 1;
Step 4 embeds gad between the edge of a wing and each fixed block of the ultra narrow edge of a wing of said slab H shaped steel;
Step 5 adopts U type anchor clamps to retrain the welding deformation of the ultra narrow edge of a wing of slab H shaped steel length direction one by one again.
Compared with prior art, beneficial effect of the present invention is following:
The present invention can prevent that the ultra narrow edge of a wing of slab H shaped steel from producing welding deformation in welding process, avoids follow-up rectification work, effectively enhances productivity, and reduces cost.
Description of drawings
The making frock front view that Fig. 1 provides for the embodiment of the invention.
The making tool structure sketch map that Fig. 2 provides for the embodiment of the invention.
Wherein:
U type anchor clamps 1
Fixed block 2
The specific embodiment
Referring to Fig. 1-Fig. 2, the present invention relates to the preparation method of the ultra narrow edge of a wing of a kind of slab H shaped steel, said method comprises the steps:
Step 2 places the ultra narrow edge of a wing of the slab behind assembled formation H shaped steel on the plate platform that adds backing plate;
Step 4 after H shaped steel is in place, adopts earlier between the gad 3 embedding edges of a wing and each fixed block, with the welding deformation of the ultra narrow edge of a wing of constraint slab H shaped steel cross-wise direction;
Step 5 adopts U type anchor clamps 1 to retrain the welding deformation of the ultra narrow edge of a wing of slab H shaped steel length direction one by one again, and U type anchor clamps 1 1400mm at interval are provided with.
In sum, can make the ultra narrow edge of a wing of slab H shaped steel, guarantee that the ultra narrow edge of a wing of slab H shaped steel does not produce welding deformation in welding process through the embodiment of the invention.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
