Embodiment

[0029] Embodiment: a kind of large-span double-layer PTFE membrane structure roof sub-unit installation and construction method, such as Figure 1-6 shown, including the following steps:

[0030] S1, model the roof structure and divide the roof into several units, the top central area is the first unit, and then divided into the second unit, the third unit, the fourth unit according to the latitude from top to bottom... the first unit N units; then divide each unit except the first unit into several equally divided blocks according to longitude;

[0031] The first unit is a polygonal structure, and the number of blocks in each unit is the same as the number of sides of the first unit.

[0032] S2, pack the unit film, pack each piece of unit film produced according to the unit shape from the center to both sides, and add a paper tube at the bend. In this embodiment, the paper tube adopts pearl cotton stick 4;

[0033] In S2, the width of the membrane body of the packaged unit...

Abstract

A kind of large-span double-layer PTFE membrane structure roof sub-unit installation and construction method of the present invention comprises the following steps: S1, roof structure is modeled, and roof is divided into several units; S2, pack unit film, will according to unit shape Each finished unit membrane is packaged from the center to both sides, and a paper tube is added at the bend; S3, on-site inspection of the unit membrane to check whether it is damaged and check the quantity; S4, installation of the outer mold; S5, installation of the waterproof membrane; S6, installation of the inner membrane Membrane installation; S7, insulation layer installation. The invention utilizes the self-designed large-span hemispherical double-layer PTFE membrane structure roof sub-unit installation and construction technology to ensure that the tension of the double-layer membrane roof membrane is in place, and the overall construction quality is better.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a sub-unit installation and construction method of a large-span double-layer PTFE membrane structure roof. Background technique [0002] At present, "National Fitness" has become an indispensable part of our people's daily life. The construction of a large number of sports venues has emerged as the times require. On the premise of meeting the requirements of building functions, more and more sports arenas with beautiful shapes and various forms Such buildings have sprung up like mushrooms after rain, especially the application of steel structure, which provides more thinking dimensions for the architectural design of sports venues. However, steel structure construction is often the focus and difficulty of engineering construction. If a reliable and effective construction plan is not formulated before construction, economic losses and safety accidents will eventually be caused, a...
