Scope

This document mainly stipulates the technical indicators, quality requirements or working methods of each link of the basic structure, architectural design, structural design, production process, manufacturing, storage and transportation, installation process and quality acceptance standards of prefabricated thermal insulation integrated external wall panels. Prefabricated thermal insulation integrated external wall panels integrate building energy conservation and industrialized production, conform to the basic national policy of energy conservation and emission reduction, and are an important means to achieve sustainable development. The purpose of compiling this standard is to solve the design, production, installation and quality acceptance of prefabricated thermal insulation integrated external walls, make their design reasonable, strengthen the control of the production and installation process, and ensure the construction quality, inspection and acceptance. The content framework of this document mainly includes the following aspects: 1) Prefabricated thermal insulation integrated external wall panels are composed of base concrete walls, Class A non-combustible insulation boards, special connectors, and finishing layers, as well as the performance index requirements of each component material. 2) The architectural design of prefabricated thermal insulation integrated external wall panels, including waterproof design, fire protection design, sound insulation design and thermal design. The joints of prefabricated thermal insulation integrated external wall panels (including between wall panels, parapets, balconies and other connecting parts) and the joints of doors and windows should be treated with waterproofing. According to the characteristics of the joints of different parts of the prefabricated thermal insulation integrated external wall panels and the requirements of the use environment, a drainage and waterproofing system combining structure and materials should be selected. The fire protection design, sound insulation design, and thermal design are determined in combination with relevant national standards and specifications. 3) The design of the maximum applicable height, seismic grade, plane and vertical layout principles, and bearing capacity seismic adjustment coefficient of the prefabricated thermal insulation integrated shear wall panel structure. For prefabricated thermal insulation integrated shear wall panels in key defense buildings, the requirements for strengthening their seismic measures should be raised by one degree. The bearing capacity of the shear wall joints should be designed in combination with the current national standard "Concrete Structure Design Code". Explain the provisions for the vertical steel bar connection of prefabricated shear wall panels. The layout principles of the connectors between the insulation board and the shear wall. 4) Structural design provisions for prefabricated thermal insulation integrated external wall panels, connection provisions between the external wall panels and the main structure, structural analysis methods and connection structures. The connection between the prefabricated thermal insulation integrated external wall panels and the main structure, and the structural members supporting the prefabricated thermal insulation integrated external wall panels should meet the conditions. The analysis method and related parameters used in the structural design of prefabricated thermal insulation integrated external wall panels. When designing the structure of prefabricated thermal insulation integrated external wall panels, the design should be carried out according to the enclosure structure. The load combination effect design value should be used for the bearing capacity calculation of prefabricated thermal insulation integrated external wall panels and connection nodes, and the load combination effect standard value should be used for the crack and deformation verification of prefabricated thermal insulation integrated external wall panels. Under the permanent design condition and seismic design condition, the values of various related coefficients when designing the bearing capacity of the connection nodes between the prefabricated thermal insulation integrated external wall panels and the main structure. The verification method of the ultimate bearing capacity. The construction requirements of prefabricated thermal insulation integrated external walls. The setting and requirements of the height, reinforcement, and connectors of prefabricated thermal insulation integrated external wall panels.
