Technical field
The utility model relates to the realm of building construction, particularly relates to the multi-functional positioning tool that is used to support the steel member in a kind of Construction of Steel Structure.
Background technology
Construction technology crucial in the field of steel structure construction comprises mounting technique and Unloading Technology.Any type of steel work all can comprise node and install and support uninstall process, and can adopt independently two cover supports or equipment to finish this two processes respectively, as design the interim frock auxiliary node of a cover and install, to be installed finishing, increase unloading equipments such as cover sandbox equipment or jack and remove frock simultaneously, unload construction after finishing replacement process.
At present, the shaped steel frock that generally adopts in the node installation process is rigid support such as H shaped steel or channel-section steel.Though during this support is used the time spent short, set up simple and easyly, the actual node lifting set-up time is long, meets the huge node of the irregular multi-branched of profile and lifts, and takies the loop wheel machine time may reach 4～5 days, the work efficiency extreme difference.During the structure unloading, frock is done disposable flame cutting, the shaped steel frock only is applicable to the little structure of unloading total position shape, and the big structure of position shape also needs to look for again supporting-point to change discharge mechanism, not only takes time and effort, and returns construction and brings security risk.
Existing steel work project, the shaped steel frock that adopts when node is installed mostly is the firm skeleton that H shaped steel combines, and does not have the gauge finder design.According to node location and size, determine the frame configuration and the H shaped steel size of frock substantially, then node is winched on the frock, utilize loop wheel machine, jack and various measuring method to carry out the three dimensions adjustment of node, repair the H beam steel shape of frock and node contact position simultaneously, until reaching installation requirement, it is fixing to remake welding.The time that this process continues may reach several days.Structure when unloading, adopt jack to replace the carrying effect of frock earlier, remove frock then and change unloading equipment, as equipment such as sandbox or special jack, pads.This shaped steel frock is applicable to that not needing extra temporary supporting system or structural element is the steel work of the geometry of rule.
There is following problems at least in frock of the prior art:
(1) it is long that node is installed the time that takies equipment such as loop wheel machine, need dispose available manpower for a long time and carry out work high above the ground, and frock is revised;
(2) between installation period, amount of labour demanded is big, time-consuming length, the carrying out rapidly of the continuous productive process that is unfavorable for constructing;
Replacement equipment process complexity when (3) unloading, unavailable machinery substitutes manpower, the security risk height, unfavorable safe construction, the process of replacement equipment is limited by the place, high-altitude, is difficult for finding reliable supporting-point, also needs to calculate in addition and simulate;
(4) the synchronism control accuracy is poor, and the flame cutting easy damaged member paint of spark that splashes produces disaster hidden-trouble.
The utility model content
Based on above-mentioned existing in prior technology problem, the utility model embodiment provides a kind of multi-functional positioning tool, can be used for supporting in the Construction of Steel Structure steel member, can assist the installation and the unloading of steel member simultaneously, do not need during this time to change and support, improve and support the convenience that uses with frock in the Construction of Steel Structure, reduced the Construction of Steel Structure cost.
The purpose of this utility model is achieved through the following technical solutions:
