Construction method for single-layer hyperbolic ETFE film of large-cantilever cable-supported grid structure
The invention belongs to the technical field of ETEE membranes, and particularly relates to a construction method of a single-layer hyperbolic ETFE membrane of a large-cantilever cable-supported grid structure. A main support is included, an assembly support is fixedly connected to the upper portion of the main support, the assembly support is of a hollow structure, and a fixing mechanism is arranged on the inner side wall of the assembly support; and the fixing mechanism comprises a supporting plate, a worm, a threaded rod, a fixing cylinder, a fixing roller and a limiting block, the supporting plate is fixedly connected to the inner side wall of the assembling support, the middle of the supporting plate is rotationally connected with the worm in a penetrating mode, and the upper end of the worm is fixedly connected with the threaded rod through a coupler. According to the invention, the leakage phenomenon caused by a gap between the ETFE film and the assembly bracket can be prevented, and the leakproofness of the ETFE film installation is effectively ensured; the wind pressure resistance of the ETFE film is improved by using different degrees of tension, so that wrinkling in the use process is avoided; the upper portion of the EFTE film is protected, the film is prevented from being damaged by birds, and the strength of measures for preventing the birds from damaging the film is improved.
本发明属于ETEE膜技术领域，尤其是涉及一种大悬挑索承网格结构单层双曲ETFE膜施工方法，包括主支架，所述主支架上方固定连接有装配支架，所述装配支架采用中空结构，所述装配支架内侧壁上设置有固定机构；所述固定机构包括支撑板、蜗杆、螺纹杆、固定筒、固定辊和限位块，所述支撑板固定连接于装配支架内侧壁上，所述支撑板中部贯穿转动连接有蜗杆，所述蜗杆上端通过连轴器固定连接有螺纹杆。本发明可防止ETFE膜与装配支架之间因产生缝隙而出现渗漏现象，有效保证了ETFE膜安装的严密性；通过使用不同程度的拉力提升ETFE膜本身的抗风压能力，避免在使用过程中出现起皱；对EFTE膜上方进行防护，避免膜受到鸟破坏，提高防止鸟破坏措施的力度。
