General technical requirements for cabin of inflatable membrane structure and controlled environments 1 Scope This document sets out the general technical requirements for cabin of inflatable membrane structure and controlled environments and the requirements for packaging, labeling, transportation and storage of products. This document is suitable for emergency applications in cabin of inflatable membrane structure and controlled environments where air is used as a support system. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB 2894 Safety signs and guideline for the use GB/T 7725 Room air conditioner GB/T 19411 Dehumidifier GB/T 30161 Coated fabrics for membrane structures GB 50009 Load code for the design of building structures GB 50073 Code for design of clean room GB 50243 Code of acceptance for construction quality of ventilation and air conditioning works GB 50346 Architectural and technical code for biosafety laboratories GB 51039 Code for design of general hospital GB 55037 General specification for building fire protection JB/T 7258 Centrifugal blower for general purpose 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 membrane material air-tight composite composed of high-strength substrates and coatings 3.2 cabin of inflatable membrane structure inflatable membrane material used as the main body of the structure to form a closed space with a certain stable shape and bearing capacity 3.3 air-rib structure formed inside the enclosed membrane material where the pressurized gas acts on Note: Its shape is usually tubular. 3.4 membrane sheet cut-out piece of membrane material 3.5 hot sealing connection method for crimping the lap parts of adjacent diaphragms together by heating and melting the surface coating of the film material or the film material itself 3.6 basic operation pressure internal and external pressure difference during the initial shape design (shape-finding or force-finding) of the inflatable membrane structure 4 Requirements 4.1 General A cabin of inflatable membrane structure is composed of the cabin body, the controlled environment in the cabin and its control equipment. Schematic diagram is shown in Annex A. The cabin body is composed of air-ribs, diaphragm doors and inflating equipment; the cabin controlled environment and its control equipment are composed of a main cabin, a buffer room, a ventilation system and an air conditioning system. When in use, it can be used independently by a single cabin, or integrated by multiple cabins.
