  • Detail

On April 19, 2017, the 2017 international kitchen and bathroom hardware industry innovation exhibition with the theme of "innovation, circulation and technology" was held in the Asian Kitchen and bathroom city in Heshan, Guangdong Province. On the afternoon of that day, Professor Li Hua of Beijing University of technology interpreted the "technical specification for the integration of residential toilet building decoration". From the dimension of architectural decoration, explain industrial innovation to guests

Professor Li Hua of Beijing University of technology interpreted on site the technical specification for the integration of building decoration of residential toilets

the technical specification for the integration of building decoration of residential toilets was jointly prepared by the kitchen and bathroom Engineering Committee of China Building Decoration Association and Beijing University of technology in conjunction with relevant units. The preparation group was established in October, 2013, the first working meeting was held in November, 2013, and it was repositioned and drafted in February, 2015. It passed the expert review on October 19, 2015. It is the first project approval standard in the field of "integration" of residential toilet design, construction and components in China. It aims to solve the integration problem of toilet, one of the two spaces in the finished housing that involve the most problems, the most complex technology and the most difficult implementation, and fills the gap in the industry. The regulation not only promotes the modernization of the housing industry, but also drives the progress of the entire architectural decoration related industry chain

now Professor Li Hua's on-site explanation of the "technical specification for the integration of building decoration of residential toilets" is sorted out as follows:

I. ideas for solving problems in the technical specification for the integration of building decoration of residential toilets

1. Follow the sustainable development principle of the whole life process of product manufacturing, installation, use, maintenance and scrap disposal

2. Guide the modernization transformation of the production mode of the whole industrial chain of housing construction

3. Promote the application of integrated assembly technology for residential building decoration, improve the versatility of products and provide continuous services

4. Establish design rules for the integration of architecture and components under the general system

II. Principle and positioning of the technical specification for the integration of building decoration of residential toilets

this specification takes the promotion of the development of housing industrialization as the principle, implements the guiding opinions of the general office of the State Council on vigorously developing prefabricated buildings, adheres to standardized design, industrialized production, prefabricated construction, integrated decoration, information management, intelligent application, and improves the technical level and project quality, Promote the transformation and upgrading of the construction industry as the goal

based on the needs of industrialization development, this procedure determines to take the implementation of "integrated" technology under the condition of integrated assembly as the basic positioning

III. integrated technology and standard design

the integrated technology of building decoration aims to realize the system integration of building structure, interior parts and equipment pipelines. It is a process of integration and optimization of relevant technical links under the condition of decentralized production

the integration of building decoration involves two industrial fields: building installation and component manufacturing. The core content is to establish a unified technical rule of space and components, and plan the necessary technical conditions for the integration of building decoration

the standardized design of procedure preparation (4.2), including: 1. Principles of standardized design; 2. Modular design principle; 3. Requirements for versatility and interchangeability; 4. Modular coordination method; 5. Modular grid design; 6. Toilet general function size series; 7. General specification series and interface positioning size of toilet components; 8. Examples of plane dimensions of standard toilets, etc

IV. modular design method

this procedure uses modular design principles and methods to standardize the boundary conditions such as geometric shape, specification size and interface position of toilet functions and component modules, so as to realize the versatility and interchangeability of toilet interior components; Through the serialization of standard modules, the selective input and diversified output of standard modules are realized

v. modular coordination method

in the industrial standardization system, the structure based on internal parts adopts the combined modulus, which is counted as "m", and the structure based on external parts adopts the split modulus, which is counted as degree m ". When" m "is given," m "should take the integer split value of" m "

article description 4.2.4 of this procedure: in the integrated design of building decoration, the space as "external parts" should adopt the split modulus, which should be counted as "m", and the interior parts as "internal parts" should adopt the combined modulus, which should be counted as "m". Based on the characteristics of decentralized production of interior parts, in this procedure, in order to facilitate the independent operation on the basis of integration, the combined modulus is defined as the secondary modulus sequence; The secondary modulus sequence is a subsystem of building modulus, and the combined modulus and split modulus should be mutually conditional and have good adaptability

according to the relevant provisions of the current national standard "building modulus coordination standard" gb/t 50002, this procedure introduces two groups of space size progressive series 3nm and 2nm, and respectively prompts the adaptation methods of space and components when the two groups of series are applied, specifically including the following contents:

Article description of this procedure 4.2.4:

1, when the static size of space is 3nm=300mm; Or when 1.5nm=150 is upgraded, the functional size and part specification can be

3m=30m; 5m=50m and 15m=150m are the upgrading base

2. When the static dimension of the space is 2nm=200mm; Or when 1nm=100 is upgraded, the functional size and part specification can be

2m=20m; 5m=50m and 10m=100m are the upgrading base

VI. application method of modular grid design

with 3nm; Taking the 1.5nm dimension series as an example, in 4.2.5 of this specification, the modular grid design is to plan the shape and assembly relationship of space, parts and components in the standard coordinate grid, so that their overall dimensions occupy an integer multiple of the grid distance

application method of modular grid design - 4.2.5 of this specification: general interface 50mm; Part specification 30mm and 20mm cm multiple

modular network design - 4.2.5 of this specification: 200mm (or 100mm) advanced grid positioning

VII. Design rules

general specification series and interface dimensions of toilet interior parts, unify the interface position between toilet parts and building pipe network, and improve the versatility and interchangeability of interior parts. Appendix B of this project

VIII. Other related technologies

1. Establish a classification system for toilet interior parts, including: wall, top, floor, doors and windows, sanitary ware, storage and accessories, equipment and pipelines

2. It suggests the integrated technical contents of pipeline separation, drainage on the same floor, and assembly and positioning of structural components and interior parts

IX. the development trend and current tasks of relevant professional fields and application technologies in the residential decoration industry

1. The establishment of integrated prefabricated decoration technology and modern standard system

2. Study on the variability of residential suite space

3. Integrate bathroom, kitchen and storage system, with emphasis on storage system research

4. Research, development and application of smart home technology
