Description

Clamp for installing membrane structure

Technical Field

The utility model relates to the technical field of membrane structures, in particular to a clamp for installing a membrane structure.

Background

ETFE (ethylene tetrafluoroethylene) is a commonly used building-like membrane structure, and is composed of a modified copolymer of ethylene and tetrafluoroethylene. It is closely related to PTFE (polytetrafluoroethylene or polytetrafluoroethylene) and has many similar properties. In recent years, it has been widely used in the membrane construction industry. ETFE may be used as a flexible film. This makes it possible to use it for creating curved transparent exterior walls. It is an ultra-light material; the double layer pad weighs only 0.70 kg/square meter, whereas the single layer of glass (6 mm thickness) weighs 15 kg/square meter. Conventional less construction of this glass is necessary support since the double layer pad ETFE only weighs about 4.5%; the use of materials with reduced amounts of raw materials reduces construction time and reduces construction costs. Most of the work fixtures for the membrane structure, which are usually seen in a production workshop, are used in the process of fixing and clamping through parts such as screws, are easy to loosen, the adjustment is troublesome in a period of time which is required to be not judged by operators, the general fixture can only be used for manually clamping, the automation degree is low, the membrane is required to be tensioned or lengthened during installation, and the conventional fixture is inconvenient to carry out the operation.
