Step 8, annex indicate: contrast beam section setting-out pattern and full-page proof, and the purlin supporting plate, the angle brace plate that needs are gone on foot afterwards welding show at the enterprising rower of sample beam section;
Step 9, rear step welding: unclamp and remove described connecting bolt, the sample beam section after the assembling is hung away and carry out the rear step and weld;
Step 10, the assembling of Standard Beam section: the Standard Beam section identical with described sample beam section to next root, repeating step 4, step 6, step 7, step 8, step 9 get final product.
Based on above-mentioned, it is further comprising the steps of: step 11, engineering ending: for last root Standard Beam section, must be with described auxiliary junction plate and described plate platform sealing-off, and described auxiliary junction plate inwardly moved to junction plate position on the full-page proof, then, simply weld at the position that described auxiliary junction plate is corresponding with described sample beam section, and repeating step 8 and step 9 get final product again.
Based on above-mentioned, it is further comprising the steps of: step 12, engineering finish: the plate platform pad is polished, wipe full-page proof, use in order to next packing engineering.
The relative prior art of the present invention has outstanding substantive distinguishing features and marked improvement, specifically, this assemble method is the comprehensive utilization of ground sample method and loose tool method, it has overcome, and junction plate is difficult for fixing in the ground sample method, need to adopt thin plate to make full-page proof, the drawback of displacement inconvenience, need not make loose tool again, only need to utilize CAD to carry out the computer setting-out, and the contrast full-size drawing carries out line of ink marker setting-out, simple and easy to do, convenient and swift, in operation as long as full-page proof is carefully checked, control the position of auxiliary junction plate well, but just continued operation of angle, avoid human factor to cause the assembling error, it is created in practice, practicable steel work crossbeam assemble method, it is simple that it has technique, occupied ground is little, cost is low, can cut the waste, be beneficial to the advantage of increasing work efficiency.
The specific embodiment
Below by the specific embodiment, technical scheme of the present invention is described in further detail.
The assemble method of crossbeam in a kind of structure steel fabrication, it may further comprise the steps:
Step 1, preparation: produce the plate platform that planeness is better, can bear 1-2 tons of weight, the arrangement mold calculates seam deformation amount and amount of contraction, determines beam section setting-out pattern;
Step 2, beam section are amplified sample: it is theoretical to use descriptive geometry, according to beam section setting-out pattern, amplify sample with the line of ink marker in plate platform, making the ratio of the real size of full-page proof size and sample beam section is 1:1, and indicates the position that needs welding purlin supporting plate, angle brace plate in plate platform;
