Description

Dimension measuring device for steel corridor installation Technical Field The utility model relates to the technical field of steel structure truss construction, in particular to a dimension measuring device for steel corridor installation. Background In steel structure truss construction, installation of the diagonal web member is a key link for ensuring stability and accuracy of the whole structure. The conventional installation method generally adopts staged operation, for example, firstly installing a vertical web member and correcting verticality, then installing a diagonal brace, a horizontal diagonal brace and the diagonal web member in sequence, and finally carrying out integral correction and welding. The concrete flow comprises the steps of jig frame installation, measurement correction, chord member positioning, vertical rod piece installation, oblique pull rod (including oblique web members) installation and the like. The installation of the diagonal web member is usually in a sequence of pushing from the middle to the two sides and relies on temporary support, lifting of the ear plates and two-point lifting processes. The outer chord member is adjusted in position during the installation process so that the diagonal web member is in position, and then the chord member is reset and fixed by spot welding. The measuring link adopts a plumb bob and a total station to carry out precision control, meanwhile, a rear section is reserved at a section position, an inclined web member is supplemented after the butt joint of an upper chord member and a lower chord member is completed, and temporary reinforcement measures are adopted if necessary. In order to improve the installation accuracy, the prior art adopts a three-dimensional lofting method and lifting point simulation to optimize the positioning of the diagonal web member, and adjusts the lifting angle through welding a special lifting lug and a steel wire rope. In the aspect of size control, the welding deformation is restrained by combining a jacking device by means of staged correction (such as girder deflection, interval measurement and deviation correction) and a pre-arching technology. However, the existing method still has the problems of complex working procedures, large temporary support demand, low correction efficiency and the like.
