Embodiment Construction

[0042] The following is attached Figure 1-6 The application is described in further detail.

[0043] The steel structure canopy mainly includes a large-span steel structure support frame, ETFE membrane laid on the steel structure support frame and decorative aluminum plate connected with the steel structure support frame, and the ETFE membrane forms the roof of the steel structure. After the ETFE film is laid on the steel structure support frame, the edge of the ETFE film is pressed and fixed on the surface of the decorative aluminum plate with an aluminum strip, and the closing operation of the ETFE film can be completed.

[0044] The embodiment of the present application discloses a construction method for closing the ETFE snap-fit ​​PVC membrane on a steel structure roof, which is used to improve the water seepage problem easily caused by the closing gap between the ETFE membrane on the steel structure roof and the decorative aluminum plate.

Abstract

The invention relates to the field of building construction, in particular to a steel structure roof ETFE buckle type PVC film closing construction method which comprises the following steps: profile installation: when a steel structure supporting frame is built, connecting and fixing a profile into which the edge of an ETFE film is clamped with the steel structure supporting frame; measuring a gap: measuring a closing gap between the profile and the decorative aluminum plate, taking the measured maximum gap width value as a processing basis of the factory manufacturing width of the PVC film, and determining a blanking length basis of shearing after the PVC film arrives at the site according to the measured gap length; the ETFE film and the PVC film with the edges provided with the connecting strips are connected with the sectional material in a clamped mode, the ETFE film and the PVC film are pressed on the sectional material in a covering mode through a gland, and then the gland is tightly connected with the sectional material; and one side, far away from the connecting strip, of the PVC film is fixed on the surface of the decorative aluminum plate by using an aluminum strip plate, so that the PVC film is used for closing up the section bar and the decorative aluminum plate. The problem that water seepage of the steel structure roof is caused by the fact that a closing-up gap is prone to occurring between the ETFE film and the decorative aluminum plate is solved.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a construction method of ETFE buckle-type PVC membrane closure on a steel structure roof. Background technique [0002] ETFE is called ethylene-tetrafluoroethylene copolymer in Chinese, and its thickness is usually less than 0.20mm. It is a transparent membrane material. After two layers of ETFE membranes are heat-bonded together, the ETFE membrane can be inflated to form an air pillow membrane structure, which is a large-span structure. An alternative material with superior quality, it has been proven to be a reliable and economical roofing material in many projects for many years due to its many advantages, and is currently mainly used in the canopy of steel structure roofs. [0003] A steel structure canopy is disclosed in the related art, which mainly includes a large-span steel structure support frame, an ETFE membrane laid on the steel structure support frame ...
