Research On Gangue Concrete Polyurethane Sandwich Panel In The Whole Assembly Housing System

The housing industry is now at an important stage of development after the rapid development, Chinese residential construction is extensive to intensive, refinement of residential construction development stage is dependent on the residential construction development direction of industrialization. Whole assembly housing residential system as a key national ministry of construction system, needs to be a complete supporting environment to promote the development of its, supporting the cladding system is one of indispensable in again. Objective environment combined with coal in Shanxi Province, this paper studies a new type of cladding system by using coal gangue, coal gangue lightweight aggregate concrete rigid polyurethane foam sandwich panel (hereinafter referred to as coal gangue concrete polyurethane sandwich board), the main work is as follows:1. According to our country’s existing plate type building materials market, study the whole assembly housing system to the specific requirements of the external wall panels. 2. In view of the coal gangue polyurethane sandwich board the actual production in the factory, combined with coal gangue concrete, rigid polyurethane foam plastics performance of the two materials, the reasonable design of production process.3. In view of the practical application of coal gangue polyurethane sandwich board, combined with the national building design code and standard atlas, outside of gangue concrete polyurethane sandwich panels do standardized design.4. In view of the coal gangue polyurethane increases plate and structure main body fit, contribute to the structure of the problem, using the software simulation and analysis of gangue concrete polyurethane sandwich wall slabs whole assembly housing system of mechanics.Although there are a large number of plate type, the domestic market but can not only realize the whole assembly and can satisfy the heat preservation, heat insulation, sound insulation, durable, also need to satisfy the economy of cladding is not much. Coal gangue concrete polyurethane sandwich board it is using the gangue this vast stores of domestic continue waste using environmentally friendly materials, reduce cost and meet the national green low carbon idea; And the use of rigid polyurethane foam to meet required for cladding heat preservation, sound insulation and other requirements. In this paper, the production technology of coal gangue concrete polyurethane sandwich board, structural details, mechanical contribution is studied, in order to contribute to the whole assembly housing system development.
