Large-load column-free arc-shaped top plate formwork and construction method thereof

Abstract

The embodiment of the invention provides a large-load column-free arc-shaped top plate formwork and a construction method thereof. The large-load column-free arc-shaped top plate formwork comprises a spliced steel truss arch structure, wherein the spliced steel truss arch structure is provided with an arc-shaped top wall, a plurality of anti-skid blocks are fixedly arranged on the arc-shaped top wall at intervals, and each anti-skid block is provided with a stopping space; supporting blocks are arranged in the stopping spaces of the multiple anti-sliding blocks in a one-to-one correspondence mode, and a top plate formwork is arranged on the sides, away from the arc-shaped top wall, of the supporting blocks. According to the assembled steel truss arch structure, through the assembled structure in the horizontal direction and the vertical direction, on-site welding operation is not needed, the steel truss arch structure better meets the mechanical requirement of theoretical calculation, waste of materials is reduced, and due to the fact that the steel truss in the vertical direction of the arch structure is necessarily segmented, therefore, the vertical support in a certain area can be independently manufactured or replaced, and maintenance cost and manufacturing cost are low.

Description

technical field [0001] The invention relates to the technical field of steel truss manufacture, in particular to a large-load column-free curved roof formwork and a construction method thereof. Background technique [0002] Steel trusses are widely used for roof support of buildings. The traditional steel truss is an integral structure or a welded structure, which requires on-site fabrication and installation, which is difficult to install, and when a part is damaged, it needs to be replaced as a whole, which undoubtedly increases the construction cost. Based on the above problems, assembled steel trusses are disclosed in the prior art, which can effectively solve the problem of difficult installation. [0003] In the process of realizing the present invention, the applicant found that there are at least the following problems in the prior art: However, the existing steel truss divides the original integral steel truss into several pieces in the horizontal direction, and th...

Problems solved by technology

[0003] In the process of realizing the present invention, the applicant found that there are at least the following problems in the prior art: However, the existing steel truss divides the original integral steel truss into several pieces in the horizontal direction, and the steel truss in the vertical direction However, the necessary reasonable division is not carried out, which makes the overall roof unable to fully meet the mechanical requirements of theoretical calculations, resulting in a waste of materials. At the same time, the vulnerable positions of the column-free arc-shaped roof with large loads need to be strengthened in a targeted manner, while the aforementioned The steel truss of the assembled structure cannot be separately manufactured for the parts that need to be strengthened in the vertical direction of the roof. Based on the aforementioned problems, the present invention is proposed
