Abstract
The invention relates to an improved method of making a steel structure plate assembly crisscrossed post, which is characterized in that the single components are made by first assembling and welding two H-shaped bars, and then cutting one of the two H-shaped bars into two same T shapes along the center of a web plate; during assembly, welding and shaping, the two same T shapes cut are welded and fixed in the H-shaped bar web plate through diagonal alternation and circulation. The method of the invention changes the ordinary practice of the prior art by first making two H-shaped bars and then cutting one of the H-shaped bars; in this way, two faces of the T-shaped are in parallel and are well vertical to the web plate, so as to reduce the welding deformation of transverse plates and vertical plates and effectively ensure the verticality between wing plates and the web plate, straightness and torsion resistance of the assembly bars. And upon final assembly and welding, through diagonal alternation and circulation welding, the assembly deformation is reduced and 100 percent hole correction can be achieved basically without need of extra calibration, which greatly improve the on-site assembly production efficiency.
Description
Technical field
The present invention relates to the improvement to the steel work method for preparing plate-patched cross-column, it is little to relate in particular to a kind of welding deformation amount, and sheets thus obtained patched cross-column appearance and size precision is good, the method for preparing plate-patched cross-column that connecting hole group contraposition is accurate, easy for installation.
Background technology
Plate-patched cross-column in the steel work (Fig. 1), it is important head tree in the steel structure frame, when guaranteeing Steel Structure Installation between the levels column and between cross post and the beam connecting hole group accurately to hole and high perforated percentage, straightness accuracy, verticality, torsion resistance to the cross post require high, if deviation, then can cause assembling to the hole difficulty, need manually repair the hole and guarantee, increase the assembling difficulty greatly porosity.Prior art is made plate-patched cross-column, is to adopt to be welded into 2 T type rod members and 1 H type rod member by steel plate, and then with 2 involutory H type bar web plate centers that are welded in of T type rod member.Yet owing to become in the T type process at the steel plate assembly welding, its riser is connected two bights with transverse slat (wing plate), there is not constraint during welding, cause welding deformation amount big, make the verticality poor (Fig. 2) of the T type rod member that the plate welding connects, side sway twist serious (Fig. 3), and the invar plate thickness is bigger, be difficult to after the distortion be corrected in the Measurement Allowance, cause having a strong impact on group hole contraposition, cause difficulty is installed, influence the assembled on site work efficiency.This defective becomes a big obstacle of long-term restraining plate patched cross-column, fails all the time in the industry effectively to be solved.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of welding deformation amount little, sheets thus obtained patched cross-column appearance and size precision is good, the method for preparing plate-patched cross-column that hole group's contraposition is accurate, easy for installation.
The object of the invention realizes, main improve be earlier respectively the plate welding connect and make two H type rod members, then one of them H type rod member is severed into two identical T types along the web center, again two identical T types are butt-welded in H type bar web plate center, composing plate is pieced together cross bar, and the sheets thus obtained patched cross-column deflection of the method is little, proofread and correct easily, workload is little, has overcome the big deficiency of prior art for preparing welding deformation amount, realizes the object of the invention.Specifically, method for preparing plate-patched cross-column of the present invention comprises the single member of welding production, the assembly welding moulding, it is characterized in that making single member and make two H type rod members, then one of them H type rod member is severed into two identical T types along the web center for the first welding of plate respectively connects; Two identical T types to severing during the assembly welding moulding are fixedly welded on H type bar web plate center by the diagonal angle alternate cycles.
Preparation method of the present invention in addition, the thermal deformation that produces when reducing that further H type rod member severed into two identical T types, a kind of web that one of them need be severed H type rod member that is more preferably, when blanking, cut into a connection shape earlier at the need place of severing or, be welded into H type rod member, when secondary flame is severed two boards spot welding splicing, reduced the flame cutting quantity, thereby reduced thermal deformation, indeformable substantially in the time of can accomplishing to sever, further improve the plate welding and connect the back precision.
Method for preparing plate-patched cross-column of the present invention owing to change the common way of prior art, by making two H type rod members earlier, cuts one of them H type rod member again, obtains two identical T type rod members, composing types then.Like this in H type rod member welding process, can be by the welding of diagonal angle alternate cycles, the constraint of opposite side makes the portion of hot distortion be cancelled, gained T type rod member two sides is parallel and good with the web verticality, thereby reach the welding deformation amount that reduces transverse slat and riser, make that the verticality of wing plate and web and straightness accuracy, the torsion resistance of composition rod member can both effectively be ensured, during last assembly welding, weld by the diagonal angle alternate cycles, the combined deformation amount is little, substantially do not need to proofread and correct separately, still can reach 100% pair of hole of hole group, improved assembled on site production efficiency greatly.
Below in conjunction with a specific embodiment, further specify the inventive method.

The specific embodiment
Embodiment 1: referring to Fig. 4,5, cut each steel plate by designing requirement, respectively by diagonal angle alternate cycles welded H type rod member, one of them H type bar web plate 1 center is when blanking is cut, it is solid to press the 400mm range points, the solid length 80～100mm of point, elder generation's flame cuts into and to connect a shape 1.1, be welded into the H rod member after, be cut into 2 identical T types along this connecting line again, at last 2 T types are opposite to another H type bar web plate center, be welded to form plate-patched cross-column by the diagonal angle alternate cycles, check verticality at any time with angular templet during assembly welding, adjust welding sequence and welding capacity, proofread and correct a little behind the welding fabrication to stipulating requirement, the line drilling.
Embodiment 2: if material is not at hand, then will weld the H type web that needs incision, cut into two wall scrolls, elder generation's straightening, leveling, two wall scroll spot welding are linked together, form web 1, weld two wing plates 2 again and make H type rod member, and then being cut into two T type rod members by the spot welding connecting line, assembly welding is in H type bar web plate center.
