Abstract
The present invention relates to manufacture process of large span superposed beam of spliced plates. The present invention features that H-shaped monospars are first made through cutting one H-shaped web as the upper spar, cutting one other H-shaped web as the lower spar into the shape fitting to the upper spar, and welding wing plates to two webs to form two, one upper and one lower, H-shaped monospars, and then superposed and connected through fitting drilled holes. The present invention has high in-situ assembling efficiency and high product quality.
Description
Technical field
The present invention relates to a kind of plate and piece together large span load-bearing stoplog preparation method, especially a kind of superposed surfaces planeness height, and can realize the 100% large span method for preparing plate assembly composite spliced beam of boring a hole.
Background technology
Steel construction piece wide span bearing plate assembly composite spliced beam (Fig. 1), heavy duty boiler framework top board stoplog for example, because of load 5000T greatly for example, span reaches greatly about 30-45 rice, about 5500mm～8000mm,, be usually designed to two H type rod member beam A up and down by carrying designing requirement depth of beam owing to be subjected to transporting the limit for height restriction, carry out superimposed assembling by the scene again, connect two H rod members, one wing plate fixed combination up and down by bolt.For improving the bearing capacity of stoplog, H type rod member all designs and produces into little arch structure up and down.H type rod member is stressed evenly up and down in order to make, and improves combination back bulk strength, and the smooth of H rod member two superposed surfaces is necessary up and down, usually flatness required to be controlled at 1mm/M
2In, can effectively guarantee enough CONTACT WITH FRICTION between the stoplog bonding surface up and down like this.
The preparation of prior art stoplog is to make H type rod member single-beam A up and down earlier respectively, and respectively in upper and lower H type rod member single-beam superposed surfaces line, boring 4, penetrates bolt by the superimposed assembling in scene again and be combined into stoplog.The preparation of little arch H rod member single-beam, be earlier 2 H bar web plate 1 and 2 to be cut the formation two sides with arch 1.1,1.2,2.1,2.2 (Fig. 2) in both sides up and down, at web both sides arch face welding wing plate 3.1,3.2 about in the of 1,2, form the two sides then with little arch H type rod member single-beam.Yet because the upper and lower wing plate 3.1,3.2 of single H member of forming stoplog uniform thickness, also not wide not, and differ greatly, be dissymmetrical structure up and down; Secondly, two H rod member single-beam superposed surfaces connecting holes more than 4 have 2000-3000 hole usually; Besides, by weighted design, whole arch camber requires about 15-20mm.Above-mentioned H rod member single-beam web up and down cuts into the two sides arch, the welding wing plate is made the H rod member, and rule in superposed surfaces respectively, boring method, because the plate welding connects the arch camber respectively of H rod member single-beam, add not uniform thickness of lower wing plate, not wide, inevitably temperature distortion in welding process, be difficult to effectively guarantee the planeness of H rod member single-beam superposed surfaces up and down, and the distortion post-equalization is very difficult, not only the bulk strength of stoplog is made up in influence, and separately line of H rod member single-beam superposed surfaces up and down, punching, there is error in itself, superposed surfaces out-of-flatness in addition, make the requirement that is difficult to reach perforated percentage 100% after superimposed, carry out the bore hole correction in the time of can only on-the-spotly making up, the assembled on site difficulty is big, and work efficiency is low.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of superposed surfaces planeness height up and down is provided, superimposed back perforated percentage height can reach 100% method for preparing plate assembly composite spliced beam of boring a hole.
The object of the invention realizes, the main improvement is that H rod member single-beam is up and down made superposed surfaces is the plane, and another side is domes in the same way, again after the superimposed plane drilling of a H rod member beam, H rod member beam two planes are superimposed up and down then, join and bore another H rod member superposed surfaces connecting hole, thereby overcome the deficiencies in the prior art, the gained stoplog, superposed surfaces planeness height not only, and on-the-spot superimposed installation can realize 100% perforated percentage, greatly reduces the assembling difficulty, realized goal of the invention.Specifically, method for preparing plate assembly composite spliced beam of the present invention, comprise that making the plate that is little arch respectively pieces together H type rod member single-beam, hole in H type rod member superposed surfaces, it is characterized in that making H type rod member single-beam is: the H web top of putting the beams in place is cut into set the arch limit earlier, bottom cuts into flat side, the H web bottom of underbeam cut into last web in the same way indent with the camber arch, the top cuts into flat side, respectively at the both sides up and down of two webs welding wing plate, making superposed surfaces is the type of the H up and down rod member single-beam of the monolateral arch in the same way in plane then; Again the superimposed plane of a H rod member single-beam wing plate punching; H rod member single-beam is superimposed by the plane up and down at last, joins and bores another superimposed plane of H rod member single-beam wing plate connecting hole.
For being reduced at another H rod member single-beam superposed surfaces drilling, the present invention is a kind of better to be the superimposed plane of H rod member single-beam wing plate punching on stoplog earlier, and H rod member single-beam is superimposed by the plane up and down then, joins and bores H rod member single-beam plane wing plate connecting hole down.
Method for preparing plate assembly composite spliced beam of the present invention, gained H rod member single-beam superposed surfaces is a flat face, the planeness height, easier being guaranteed of H rod member single-beam superposed surfaces planeness so up and down, the plane cooperates tight, and the superposed surfaces gap is little, combination stoplog bulk strength height; Another H rod member single-beam superposed surfaces connecting hole for superimposed back is the drilling of mould to hole, it is hereby ensured underbeam superposed surfaces 100% perforated percentage, thereby has improved assembled on site efficient greatly, has not only guaranteed the perforation quality but also saved operation.The compound stoplog of the inventive method preparation, the straight not arch camber of H rod member single-beam superposed surfaces up and down (being the only monolateral arch camber of H web), and the equal arch camber in both sides up and down of prior art H rod member single-beam web, this is that the inventive method is different from art methods feature place.
Below in conjunction with a specific embodiment, further specify the inventive method.
