Laws and regulations are the only way for human beings to move towards order and kindness. The formulation of various technical regulations is an important part of China's legal work. However, if there is no reliable supervision system, some technical regulations will inevitably appear. Avoid arbitrary behavior in code implementation. When designing, it is very important to review and review the Code for Fire Protection of Renovation Works and Building Decoration 20 17 to consider and pay attention to the following issues.

An application. The announcement of "Code for Design of Interior Decoration of Buildings" has been adopted as the national standard with the number of GB50222-20 17, and will be implemented on April 20 18. Before that, you have to implement the Code for Fire Protection Design of Interior Decoration of Buildings CB50222-95.

Because of the scope of this review, there will be changes between the old and new systems. Theoretically, the code is only applicable to some construction projects, and can be started before and after the completion of the original code. If the project can meet the requirements of the code, it is suggested that the code 20 17 for fire protection of building decoration should be based on the code, so as to prevent the corresponding detection elements from causing unnecessary disputes in the fire acceptance process after the implementation of the new code 1 month.

Second, the scope of application. This code only applies to the interior decoration of buildings, not to the exterior design and decoration of buildings. At present, various types of decorative boards, insulation boards, etc. Various materials, including ceramics, slates, metals and inorganic materials with excellent fire resistance, as well as foam for the outer wall shell structure, are located on the outer wall. Interior, but still belongs to the exterior design. Whether the fire performance is considered within the scope of this specification shall be realized according to the Code for Fire Protection of Building Decoration 20 17, such as the Code for Fire Protection of Building Design GB500 16-20 14. For rooms with internal thermal insulation in the building, although the thermal insulation function is mainly due to the location in the building where its application belongs, it should also be realized according to the specifications. The Code has made some provisions on civil buildings and industrial buildings, but the focus is on civil buildings, which are explained in detail. Including all residential and public buildings, such as office buildings, commerce, service industries, education, medical research, culture, transportation, justice, memory, comprehensive civil buildings, etc. [0x9A8B According to the feedback implementation for many years, the opinions obtained from the review are that the selection of specific websites and interior decoration materials is further improved, and the code for fire protection of building decoration is 20 17, so as to avoid doubt.

Third, handle the relationship between safety and beauty. The specification requires that the selection of interior decoration materials should conform to safety. Because the design of decoration has high aesthetic requirements, it is necessary to give consideration to safety and beauty.

According to our investigation on the present situation of existing engineering renovation and our understanding of decorative materials, most of the materials that can be used in the original specification are not restricted by the use of this revised edition, such as rock wool, glass wool, gypsum board, oak, etc. Some materials, such as plastic raw materials, wooden hanging boards, plywood and wall decoration, can also meet the specification requirements through treatment, such as decorative materials used in electric heating systems; Only a small amount of flammable materials will be restricted. Code for Fire Protection of Building Decoration 20 17 is even banned in some places. If the terms of using porous or foam materials on the top or wall are deleted from the original specification, the test should be carried out in strict accordance with the requirements of the specification. Materials.

The fourth is to test the decoration materials. The burning degree of decoration materials is determined by professional testing institutions in accordance with relevant national standards. The so-called professional testing institutions refer to specialized testing units with statutory inspection rights approved by national, provincial and municipal technical supervision departments.

It is the most basic task to establish the testing method and grading standard of the combustion performance of the selected materials. Code for Fire Protection of Building Decoration 20 17 There are many kinds of interior decoration materials, and new materials are also full of tricks. Different materials have different test methods and classification standards. Some only have test method standards, but no combustion performance standards. Some detection methods also form national standards or are not perfect and systematic. According to the principle of using existing standards as much as possible, we can also refer to some foreign standards.

Because there is no specific method to detect and judge B3 grade materials in current national standards, B3 grade decorative materials cannot be detected.

In the process of decoration, the internal structure of buildings is often complicated. The fire protection code for building decoration is 20 17, and all materials are not used. For example, many planes are not made of a single material, and many charcoal decorations are made on the glass wall; Fixing furniture as a wall; In the decoration, the materials of floors and walls are not clearly classified as "walls crawling on the floor". In this case, the materials must be in strict accordance with the materials. The materials selected for the parts must meet the performance requirements of the corresponding parts.

The revised version of this specification deletes the detection methods in the appendix of the original specification. Code for Fire Protection of Building Decoration 20 17 Indoor decoration materials should be tested according to GB8624-20 14, so the testing contents of some materials have changed. If the original flame retardant test method of B 1 grade material is cancelled, it cannot be used as the fire resistance test method of material performance. Most materials are more complicated than the original materials, so as a class A material, it is necessary to carry out calorific value test. ? SBI test is used for detailed testing to determine the flame retardant properties of materials.

The above is the code for fire protection of building decoration 20 17? Some information about the problems that should be paid attention to, I hope it will be useful to you.
