Problems solved by technology
[0002] At present, the construction process of multi-channel conjoined steel truss is to build the formwork support frame of the assembled construction floor first, and then use the lifting equipment on the construction site to hoist, position, weld, and assemble each component on the assembled construction floor until the final shape. Due to the high-altitude operation of the process, the risk is high, and it is difficult to connect each component in the aerial operation, and the welding quality cannot be guaranteed

The invention provides a multi-connected-body truss integral elevating reverse work construction system and method. Vertical guide rails, sliding blocks, elevating mechanisms, steel strands and top trusses are adopted. The vertical guide rails are arranged on the opposite sides of adjacent building structures along the elevating path correspondingly. The top of each of the two adjacent building structures is provided with one top truss. Each top truss is provided with one elevating mechanism. The elevating mechanisms are connected with the corresponding ends of the top of a multi-connected-body truss through the steel strands. The two sides of the multi-connected-body truss are provided with the sliding blocks matched with the corresponding vertical guide rails. The multi-connected-body truss is spliced on the ground in advance, the aerial welding and splicing safety risk is reduced, and accurate positioning between corridors in the multi-connected-body truss is improved. Since the multi-connected-body truss vertically upwards runs along the vertical guide rails, horizontal displacement of the multi-connected-body truss in the elevating process is avoided, accurate connection between the multi-connected-body truss and the two adjacent building structures is achieved, the installing quality is effectively improved, and the construction period is reasonably shortened.
Description
technical field [0001] The invention relates to the technical field of steel structure installation, in particular to a construction system and method for overall lifting and inversion of multi-channel connected trusses. Background technique [0002] At present, the construction process of multi-channel conjoined steel truss is to build the formwork support frame of the assembled construction floor first, and then use the lifting equipment on the construction site to hoist, position, weld, and assemble each component on the assembled construction floor until the final shape. Due to the high-altitude operation of the process, the risk is high, and it is difficult to connect each component in the aerial operation, and the welding quality cannot be guaranteed. Contents of the invention [0003] In order to overcome the practical problems and shortcomings of the above-mentioned prior art, the present invention provides a multi-channel connected truss overall lifting and revers...
