Abstract
The invention provides an anti-deformation method for manufacturing of a steel plate splice welding cross column. A blanked plate is directly used for assembly; wing plates and a web are assembled together to form main H-shaped steel; another two T-shaped branches are assembled; the assembled main H-shaped steel is subjected to full-automatic submerged-arc welding; the assembled T-shaped branches are assembled on the H-shaped steel obtained after submerged-arc welding; the formed cross column obtained after assembly is well fixed; and welding is conducted through a semi-automatic submerged arc welding machine. According to the anti-deformation method, the cross column obtained after splice welding can be prevented from deforming and can accurately correspond to a beam connecting hole, and installation can be more smooth.
Description
Technical field
The present invention relates to a kind of steel plate butt welding cross column and make distortion-free method.
Background technology
Steel construction cross column is the important feature post in framework, upper and lower layer column and the accuracy of connecting hole group between cross column and beam when its quality directly affects steel construction in-site installation; Prior art processing cross column is for process with the direct welding of sheet material, and the size of its welding is difficult to accurate assurance, and the cross column causing welding to go out is difficult to corresponding with connecting hole group between beam, and scale error is comparatively large, adds difficulty to in-site installation.
Summary of the invention
The present invention proposes a kind of steel plate butt welding cross column and make distortion-free method, the plate of direct use blanking is assembled, together with wing plate stands in web group, form main H profile steel, T-shaped group of Ling Liangge branch is stood, full-automatic submerged arc welding is carried out by organizing the main H profile steel stood, the T-shaped branch group assembled is contained in H profile steel that submerged arc welding completes, the cross column of assembled formation is fixed, semi-automatic submerged arc welding machine is used to weld, the cross column distortion that the present invention can prevent welding from going out, can be accurately corresponding with beam connecting hole, makes installation more smooth.
The present invention realizes particular by following technical scheme:
A kind of steel plate butt welding cross column makes distortion-free method, comprises the following steps:
Step 1, cutting stock: the cutting stock carrying out plate according to drawing requirement size;
Step 2, the assembling of plate: directly use the plate of blanking to assemble, form main H profile steel together with wing plate stands in web group, T-shaped group of Ling Liangge branch is stood;
Step 3, full-automatic submerged arc welding: carry out full-automatic submerged arc welding by organizing the main H profile steel stood;
Step 4, the assembling of Liang GeTXing branch: the T-shaped branch group assembled is contained in H profile steel that submerged arc welding completes;
Step 5, the semiautomatic submerged arc welding of T-shaped branch connects: fixed by the cross column of assembled formation, uses semi-automatic submerged arc welding machine to weld;
Step 6, parts plate: the cross column made is carried out line assembling, complete.
Preferably, in step 4, Liang GeTXing branch requires that centered vertical is installed, and spot welding will meet spot size at 20-30mm, and spacing is between 200-300mm.
Preferably, in step 5, welding will adopt the order of diagonal angle alternate cycles welding to carry out welding, and electric current must not more than 300A, voltage 35-38V, and welding will without letup, can not middlely stop, and is strictly on guard against that inequality of being heated produces distortion.
The beneficial effect that the present invention produces is: first form main H profile steel, and in group Li LianggeTXing branch, plate welds, and H profile steel need use submerged arc welding, and other two branches are after assembling, in the welding of use semiautomatic submerged arc welding, and last part plate secondary assembling etc.The cross column distortion that the present invention can prevent welding from going out, can be accurately corresponding with beam connecting hole, makes installation more smooth.
Detailed description of the invention
Be clearly and completely described the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of steel plate butt welding cross column makes distortion-free method, comprises the following steps:
Step 1, cutting stock: the cutting stock carrying out plate according to drawing requirement size;
Step 2, the assembling of plate: directly use the plate of blanking to assemble, form main H profile steel together with wing plate stands in web group, T-shaped group of Ling Liangge branch is stood;
Step 3, full-automatic submerged arc welding: carry out full-automatic submerged arc welding by organizing the main H profile steel stood, welding current, voltage, welding wire, solder flux and speed meet code requirement, and welded seam will meet the quality requirement of full penetration weld or partial penetration weld seam as requested;
Step 4, the assembling of Liang GeTXing branch: the T-shaped branch group assembled be contained in H profile steel that submerged arc welding completes, Liang GeTXing branch requires that centered vertical is installed, and spot welding will meet spot size at 20-30mm, and spacing is between 200-300mm;
Step 5, the semiautomatic submerged arc welding of T-shaped branch connects: fixed by the cross column of assembled formation, semi-automatic submerged arc welding machine is used to weld, welding will adopt the order of diagonal angle alternate cycles welding to carry out welding, electric current must not more than 300A, voltage 35-38V, and welding will be without letup, middlely can not stop, being strictly on guard against that uneven generation of being heated is out of shape;
Step 6, parts plate: the cross column made is carried out line assembling, complete.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
