Description
Technical field：
The invention belongs to steel structure modularization technical field of buildings, it is related to one kind and utilizes rotating device to carry out module steel frame
The method of group weldering.
Background technology：
Steel structure modularization building is a kind of highly integrated assembled architecture, supporting generally by steel structure frame and with it
Three plate body systems add decorations to constitute.Wherein steel structure frame is generally the box type that the weldering of the component groups such as square steel, H profile steel is constituted
Space structure, is welded using manual electric arc welding mode group generally on factory lines and made, but due to the characteristic of its space structure,
Group weldering needs to aid in scaffold, split heads or group weldering platform etc. as shown in Figure 1 along with component upset could complete different portions often
Position weld seam welding (high position can be welded using the device high-rise working such as scaffold and platform, lower position by workman's standing ground group,
Weld after upper side weld seam, downside weld seam is switched to upper side by flip component to be continued to weld, to ensure downhand welding operation).
Existing apparatus technology has the disadvantage that：
1st, group weldering efficiency is low：Auxiliary is needed to set up and movable Scaffold or operating platform during group weldering, in addition it is also necessary to coordinate and carry out
Steel frame lifting upset；
2nd, security is low：Ascend a height operation and lifting upset are needed, increase is dangerous；
3rd, quality is difficult to ensure：High-rise working inconvenience control, multi-faceted welding quality it is difficult to ensure that；
4th, economy is low：Because inefficiency and quality inconvenience control cause added cost；
5th, workman's operating environment is poor, climbs low.
The content of the invention：
It is an object of the invention to provide a kind of method that the weldering of module steel frame group is carried out using rotating device, existing skill is solved
Need to set up present in art and movable Scaffold and platform, the group weldering efficiency for needing steel frame lifting upset etc. to bring is low, behaviour
Make the problems such as potential safety hazard is big, group weldering quality control is difficult, cost is high.
As above conceive, the technical scheme is that：A kind of method that the weldering of module steel frame group is carried out using rotating device,
It is characterized in that：Comprise the following steps：
