Authoritative interpretation: Hainan technical standard for precast interior decoration
The full text of the standard is divided into 8 chapters, including 1 general provisions, 2 terminology, 3 basic provisions, 4 design, 5 manufacturing and transportation, 6 construction and installation, 7 project quality acceptance, and 8 use and maintenance.
It is forward-looking, normative and practical.
The standard is the first special standard for precast interior decoration in Hainan Province.
In the aspect of system integration design, the full text of the standard implements the design concept of systematization, integration and integration of precast interior decoration, coordinates the requirements of various disciplines, plans the needs of various stages, and relies on the building information model (BIM) technology to realize the information management and professional collaboration in the whole process; In terms of eliminating common quality problems, the standard requires that the construction method of dry operation construction process be adopted on the site to solve the problems of many wet operations, poor construction accuracy, complex processes, long construction cycle, relying on the level of on-site workers and difficult to guarantee the construction quality on the traditional construction site.
After several rounds of revision, the standard passed the expert review on April 22, 2022.
During the preparation of the standard, the preparation team followed the current relevant national laws, regulations and technical standards, fully investigated the application of precast interior decoration in the province and the technical system products of manufacturers of precast interior decoration outside the province, widely solicited the opinions of all social parties, and held several rounds of preparation seminars to clarify the preparation objectives, preparation depth and technical content of the standard.
Under the premise of fully implementing the policy of building industrialization and green sustainable development, precast interior decoration, as an important part of the technical requirements of precast buildings, is the only way for high-quality development in the field of housing construction, and also an important part of the promotion of precast buildings in our province.
In the next step, our office will promote the implementation of the standards through extensive publicity, publicity and implementation training, and issuance of supporting policy documents.
The content is detailed and defines the requirements for precast interior decoration in the stages of design, component manufacturing and transportation, construction and installation, project quality acceptance and use and maintenance.
The content of the article fully considers the regional characteristics of Hainan Province and the development status and objectives of precast interior decoration, and guides to solve the five major needs in the application of precast interior decoration projects in Hainan Province, such as system integrated design, elimination of common quality problems, green health, high performance, intelligence and informatization.
In terms of article arrangement, according to the requirements of standard preparation depth, the procedures of design, production, transportation, installation, acceptance and maintenance of cast interior decoration components shall be prepared in sections, so as to make the logic of this standard clear and easy to consult.
The high-quality development of housing construction is the key to the transformation of real estate economic development, and it is also the urgent demand of residents for high-quality living.
The standard fully considers the matching with the relevant contents of the current standards, such as the design standard for interior decoration of fully decorated residential buildings in Hainan Province, the code for quality acceptance of decoration works of fully decorated residential buildings in Hainan Province, the technical standard for standardized design of precast buildings in Hainan Province, the new version of the calculation rules for the assembly rate of precast buildings in Hainan Province in 2021, and the technical standard for the production and installation of precast concrete components in Hainan Province, Jointly build Hainan precast building technology system.
The implementation and release will play a guiding role in the promotion and application of precast interior decoration in Hainan Province, further help the construction of precast building standard system in Hainan Province, and promote the development of the whole industrial chain of precast buildings.
The standard emphasizes the quality requirements at all stages of design, manufacturing and transportation, construction installation, project quality acceptance, use and maintenance, and requires the use of BIM Technology, Ensure the accuracy and quality traceability of parts and engineering information transmission; In terms of green health, the standard requires that the quality of indoor thermal environment, light environment, sound environment and air environment be improved and improved through the use of energy-saving and green environmental protection materials and components, so as to reduce the impact of adverse environment on buildings, and implement green construction and other measures to achieve green health requirements; In terms of high performance, the standard puts forward design and construction methods and quality requirements for the performance indicators of major materials such as cast interior parts and equipment pipelines, as well as building structure stress, fire protection, energy conservation, sound insulation, sanitation and epidemic prevention, and puts forward inspection methods for corresponding performance requirements in the chapter of “project quality acceptance”, which is both instructive and practical; In terms of intelligence and informatization, the standard requires the use of building information model (BIM) technology in the provisions of design, manufacturing and transportation, construction and installation, project quality acceptance, use and maintenance stages, and takes into account the intelligent professional application to achieve integrated fine design, management and traceability of component quality and production related information, simulation, guidance and management of the whole construction process, review of BIM design documents and electronic documents Deliver and receive, establish the use and maintenance database of interior decoration parts, and implement the principle of “information management and intelligent application” of precast interior decoration.
In order to ensure the high-quality development in the field of precast interior decoration technology of civil buildings in Hainan Province, our department has organized the preparation of Hainan technical standard for precast interior decoration dbj46-063-2022 (hereinafter referred to as “the standard”).
