Abstract

The invention discloses a construction method of a large-diameter barrel cabin top, and relates to the technical field of building construction engineering. H-shaped inclined steel beams are designed in groups. Welding of an H-shaped inclined steel beam assembly is finished on the ground. After a ring beam is temporarily positioned above a barrel body, the welded H-shaped inclined steel beam assembly is lifted and is respectively welded with the barrel body and the ring beam. Finally, temporary positioning pieces of the ring beam are removed. Due to the fact that the welding of the H-shaped inclined steel beam assembly is finished on the ground, the H-shaped inclined steel beam assembly is lifted between the barrel body and the ring beam according to a suspension center on a design drawing and then is welded, at least 75% of quantity of work on the upper air is saved, quality is effectively guaranteed, safety and high-labor-intensity defects brought by the work on the upper air are greatly reduced, work efficiency is improved, and construction cost of the large-diameter cabin top is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of building construction engineering, in particular to the roof construction technology of large-diameter silos. Background technique [0002] In the current large-diameter silo construction process, after the construction of the cylinder is completed, scaffolding is built, and the ring beam is hoisted above the cylinder, and the ring beam is temporarily positioned at an appropriate distance from the top of the cylinder by temporary positioning parts (such as scaffolding). Then lift each I-steel inclined beam one by one, and weld the upper and lower ends of the I-steel inclined beam to the ring beam and the cylinder respectively at high altitude. This method of application requires a lot of time for high-altitude operations, and the hoisting equipment takes a long time, which is not conducive to saving construction costs. Due to the large amount of high-altitude operations, it also forms a relatively large c...
