Embodiment 1

[0032] basically as figure 1 , figure 2 and image 3 Shown, a kind of film unfolding platform that is used for ETFE membrane construction is used for flattening ETFE diamond-shaped membrane 2, and installs lasso below it, and the long diagonal line of ETFE diamond-shaped membrane 2 is about 25m in the present embodiment, short The diagonal is about 15m, and the noose is installed along the long diagonal direction of the EFTE diamond-shaped membrane 2.

[0033] The film spreading platform 1 provided in this embodiment includes a first film spreading unit and a second film spreading unit, an installation channel 10 is formed between the first film spreading unit and the second film spreading unit, and the first film spreading unit and the second film spreading unit The membrane units have the same structure and are arranged symmetrically with respect to the installation channel 10. The length of the installation channel 10 is not less than 25m, the height of the installation ...

Embodiment 2

[0038] The difference from Example 1 is that the combination Figure 4 As shown, the present embodiment also includes an automatic tightening unit. The automatic tightening unit includes two sets of drive assemblies and two aluminum tubes 22. The two sets of drive assemblies are respectively arranged at the entrance and exit of the installation channel 10, wherein the drive assemblies include The slide rail 20 and two driving parts 21, the two driving parts 21 are arranged symmetrically with respect to the installation channel 10, the driving part 21 includes a power trolley, the power trolley can run automatically on the slide rail 20, and a deceleration motor is provided on the power trolley, The output shaft of the deceleration motor is horizontally coaxially fixed with a connecting cylinder, the inner diameter of the connecting cylinder is not less than the outer diameter of the aluminum tube 22, a number of connecting blocks are evenly distributed on the inner wall of the ...

Abstract

The invention belongs to the technical field of ETEF film installation, and particularly discloses a film spreading platform for ETFE film construction. The film spreading platform is used for flatly spreading an ETFE rhombic film, the long diagonal line of the ETFE rhombic film is 25 m, the short diagonal line of the ETFE rhombic film is 15 m, the ETFE rhombic film comprises a first film spreading unit and a second film spreading unit, an installation channel is formed between the first film spreading unit and the second film spreading unit, the length of the installation channel is not smaller than 25 m, and the height of the installation channel is not smaller than 1.3 m, the width of the installation channel is not smaller than 2.5 m, the outer contours of the first film spreading unit and the second film spreading unit are in an equilateral trapezoid shape, and the distance from the short edge to the long edge of the trapezoid is not smaller than 6.3 m. By adopting the scheme of the invention, the film materials transported to the site can be spread at a low altitude, an operator completes installation of the under-film lasso on the ground, the construction safety is guaranteed, the high-altitude construction steps are simplified, the construction difficulty is reduced, and a good effect is achieved in current engineering application.

Description

technical field [0001] The invention belongs to the technical field of ETEF membrane installation, and in particular relates to a membrane spreading platform used for ETFE membrane construction. Background technique [0002] In the design of large stadiums, a canopy system is usually added on the upper part of the audience seats, and the cable dome is added to the ETFE membrane structure canopy system. Through this space cable dome membrane structure system, the light transmittance of the ETFE membrane material can be used to the greatest extent. Avoid the impact of weather conditions on spectators watching the game. [0003] When the length of the large unit ETFE diamond-shaped membrane exceeds 24m, in order to protect the membrane, the direction of tightening during transportation is horizontal tightening, that is, tightening in the direction of the short diagonal of the rhombus, and in order to avoid the unit membrane during structural design. If the deflection is too la...
