Embodiment Construction
[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0027] The construction steps of the present invention include:
[0028] Step 1: Component entry and acceptance;
[0029] Step 2: Production of splicing platform and sliding track
[0030] 1 The total length of the single truss beam in this project is 30.18 meters, the beam height is 1.3 meters, and the beam width is 0.5m, 0.6m, and 0.7m. In the production and processing process, considering the convenience of on-site road transportation and the lifting capacity of tower cranes, the single-product steel The beam is divided into three sections, and the lengths of the three sections are: 9.3m, 11.58m, and 9.3m; the steel beam splicing operation platform is made of H500*300*10*20 steel, with a production length of 30 meters and a width of 2 meters;
[0031] 2. The sliding track is made of H500*300*10*20 steel, with a total length of 6...

The invention relates to a construction method for high-altitude splicing, sliding and lifting of a large-span steel beam. According to the technical scheme, the construction method comprises the steps that firstly, components enter a site and are accepted and accepted; secondly, a splicing platform and a sliding rail are manufactured; thirdly, a steel beam is spliced; fourthly, the steel beam slides; performing static load trial hoisting; according to the construction technology of lifting according to the steps and empty splicing sliding lifting of the steel beam, the large-weight steel beam can be effectively installed at the high altitude through a simple tool, the requirements for safety, reliability, economy and reasonability in the installation process are met, and the installation precision of the high-altitude large-span steel beam is accurately controlled through a total station and a level gauge; the steel beam is accurately lifted to the position between the two embedded brackets, the large-span steel beam is fixed through the I-shaped steel inclined struts, single steel beam is prevented from inclining, the arching height of the steel beam is controlled, the I-shaped steel inclined struts can be used repeatedly and recycled, and cost is reduced.
Description
technical field [0001] The invention relates to the field of building construction methods, in particular to a construction method for high-altitude splicing, sliding and lifting large-span steel beams. Background technique [0002] The installation and construction sequence of high-altitude long-span steel beams is mostly to use tower cranes or cranes to directly hoist the segmented steel beams to the installation position for fixing. Since the installation position of the steel beams in this project is between two concrete structures, the construction scope is limited and the installation height is limited. The steel beam is relatively high and the steel beam is heavier. After research, the project personnel proposed a construction method for high-altitude splicing and sliding lifting of large-span steel beams. The tower crane was used to lift the segmented steel beams to the six-story floor, with an elevation of 20.7 meters. Splicing on the six-storey floor, installing th...
