Embodiment Construction

[0014] The present invention will be further described in detail based on Figures 1-4. The high thermal insulation type ETFE membrane structure includes an ETFE membrane layer 15 with a traction cable 13 fixed on the periphery, a metal profile clamp 12 assembled in a cavity formed by a metal profile member 14 and clamps the traction cable 13, an inflatable cavity and its inflation system. The structure of the metal profile fixture 12 and the metal profile member 14 adopts the special metal profile fixture and the special metal profile member and their connection structure in the "film curtain wall structure" (see Chinese Patent Application 200810010045.1) designed by the applicant independently. Among them, each layer of the ETFE film layer is shown in Figure 1, and at least two air-filled cavities can be formed.

[0015] In this embodiment, the ETFE film layer with the traction cord 13 fixed on the periphery is composed of an outer layer film 3, an intermediate layer film 4, and ...

Abstract

A high heat preservation ETFE membrane structure comprises an ETFE membrane layer of a periphery fixed pulling cable, and a metal section clamp of a clamping pulling cable, which is assembled inside a chamber formed by a metal section component. The invention has the technical key points that: the ETFE membrane layer is composed of an outer layer membrane, a middle layer membrane and an inner layer membrane; at least two charging chambers are formed among all the layer membranes; a charging connector and a perforation gas nipple which are fixed on the layer membrane wall of all the charging chambers respectively utilize an air hose to be connected with a corresponding inflation system. The invention has simple structure and easy fabrication and installation, and effectively solves the problems of the poor insulating performance and the difficult charging of a plurality of chambers of the prior single cavity body membrane material, thereby not only improving the insulating performance of the membrane structure, but also ensuring the initial design effect of the architecture.

Description

Technical field [0001] The present invention relates to an outer protective structure of a membrane building, in particular to a high thermal insulation type ETFE membrane structure suitable for building curtain walls or roofs. It is mainly suitable for using ETFE membrane materials as surface materials and forming multiple membranes by inflating and pressing. Layer inflatable cavity (commonly known as air pillow) to meet the requirements of membrane structure building curtain wall or roof with high thermal insulation performance, which belongs to the technical field of building envelope structure engineering. Background technique [0002] ETFE film has been widely used as a thin film material in modern building curtain walls or roof structures. Among them, "ETFE" is the abbreviation of Ethylene Tetra Fluoro Ethylene in English, and the Chinese name is ethylene-tetrafluoroethylene copolymer. ETFE film material has high tensile strength, impact resistance and tear resistance. The ...
