Study On The Theory Of General Technology And The Application Of Modulus Coordination In Industrial Residential Parts

Under the background of current resource shortage and environmental crisis,it is necessary for China’s construction industry to transform into a new type of building industrialization.However,problems in the development of building parts,such as lack of standardized design of parts,inconsistency between building and parts,inconsistency of interface size and form between parts,inconsistency of standardization,generalization and serialization of parts,etc.Poor,imperfect product system.These problems are the important reasons that restrict the progress of building industrialization.In this paper,the application research of general technology and modulus coordination of parts is carried out in view of the above problems.Firstly,by taking residential parts as the main line,combing the development process of industrialized housing in China and Japan and making a deep comparative study,the paper analyses the existing problems of industrialized housing and its components in China,and draws lessons from the development process of industrialized housing in Japan,which clarifies the necessity and research direction of the research on the generalization of residential parts;Based on the study of the general structure system and the general interchange mode between China and Japan,the basic theory of the general use of residential parts is discussed,and the relationship between the standardization,integration,modularization and generalization of parts is discriminated,which provides a reference for the research of the generalization of parts.Then,based on the research of the basic theory of part generalization,combined with the investigation of the concrete prefabricated component production plant and the consultation and interview with the producers,designers and constructors,the technical conditions that must be satisfied for part generalization are summarized as follows:1)module coordination between parts;2)interface unification between parts;and 3)the performance of parts meets the national certification standards.Due to the limitation of research time and ability,this paper conducts in-depth research on modular coordination technology between parts,hoping to provide theoretical support and research ideas for the research of the latter two technical conditions of the generalization of parts.By summarizing the current situation of the development of modular coordination standards in China,and comparing with the international and Japanese standards,the development direction of modular coordination in China is summarized.This paper combs the residential parts that need to be coordinated,and explains the principle of modular grid coordination.On the basis of the theory of modular coordination,the housing is divided into three levels:structural space modular grid,functional space modular grid and two-dimensional decoration modular grid.Combining with the data of investigation and national standard,the optimum sizes of residential parts which need to be coordinated in each level are summarized,and then the modular coordination method of modular grid and parts in each level is studied.On the basis of the application method of modular coordination,this paper uses the case of modular coordination of parts and components in the fabricated concrete shear wall structure housing to test the research content and the method of modular coordination in practice,complete the transformation of theoretical research results,and obtain the design principle of industrial housing with "less specifications and more combinations"of parts and components.Finally,it is concluded that in order to realize the standardization,generalization,serialization,modularization and integration of building parts and promote the development of housing industrialization,assembly architecture design must be considered as a whole,the development strategy of "top-down" and"bottom-up" should be implemented together,and the development of informatization and digitization should be fully combined to promote the development of building industrialization.In this paper,there are 74 illustrations,53 tables and 95 references.
