Taking each floor and household of the standard floor as the unit, the structure is divided into different types of components (such as walls, beams, plates, stairs, etc.) according to the structural characteristics and the principle of facilitating the fabrication and installation of components, so as to facilitate the standardized production, installation and quality control.

From the perspective of decoration cost, the cost of full decoration is usually only higher than that of blank house, and the cost pressure is not large.

If there is a problem with the “fully decorated house”, the first thing to look for is the developer, Whether there are quality problems in the house itself or in the process of decoration engineering, developers must bear the responsibility.

The development of precast buildings is the only way to comprehensively improve the quality and quality of housing.

The advantages of this kind of buildings are fast construction speed, less restriction by climatic conditions, less environmental pollution, labor saving and improving construction quality.

The assembly construction method can effectively improve the product accuracy, solve the common problems of systematic quality, reduce the maintenance cost in the later stage of the building and prolong the service life of the building.

It is estimated that the use of precast building construction can reduce the amount of formwork by more than 85%, save water by more than 40%, save electricity by more than 10%, and shorten the construction period by more than 50%.

Under the guidance of national strategy, relevant incentive policies of the Ministry of housing and urban rural development and local governments have been issued one after another.

Environmental protection and energy conservation.

What is the precast building? The precast building takes the precast production of component factory and on-site assembly installation as the mode, and is characterized by standardized design, industrialized production, assembly construction, integrated decoration and information management.

At present, the common problems of residential construction quality have been criticized, such as roof leakage, poor sealing effect of doors and windows, cracking of thermal insulation wall and so on.

The state intensively issued policy documents on the promotion of precast buildings, and made clear requirements in development planning, standard system, industrial chain management, project quality and other aspects.

Official account of several industries:.

The materials used for fine decoration are more advanced and will be carefully designed, so it needs to consume higher cost, so the incremental cost of full decoration house is far lower than that of fine decoration house.

Quality reliability.

As early as 2002, the Ministry of construction clearly put forward the decoration standard of full decoration in the detailed rules for the implementation of commercial residential decoration in place at one time: before the house is turned over, all the fixed surfaces of all functional spaces are paved or painted, and all the basic equipment of kitchen and toilet are installed.

The backward production mode of the construction industry directly leads to the randomness of the construction process, and the project quality can not be guaranteed.

The use of precast construction can comprehensively improve the quality and performance of housing, let the people share the development achievements brought by scientific and technological progress and supply side reform, drive residents’ housing consumption, and move towards the development path of China’s housing dream in the continuous renewal.

Rebar Cross Chair

The State Council issued several opinions on Further Strengthening the management of urban planning and construction, the guiding opinions on vigorously developing precast buildings and the opinions on promoting the sustainable and healthy development of the construction industry, and put forward guiding objectives and plans for the development of precast buildings, marking that the country has officially promoted the promotion of precast buildings to the height of the national development strategy.

New urbanization is people-centered urbanization, and housing is the biggest livelihood problem of the people.

The difference between standardized construction and traditional assembly manufacturing.

The components are processed in the factory, the types of components are relatively few, and the forms are unified, so that the on-site construction is standardized and standardized, and the component quality is fully guaranteed.

Precast buildings are mainly divided into concrete precast buildings, steel structure precast buildings and wood structure precast buildings.

The development trend of precast buildings began with the green building action plan issued by the national development and Reform Commission and the Ministry of housing and urban rural development in 2013.

It integrates various business fields from R & D and design, production and manufacturing, on-site assembly and so on to realize energy conservation, environmental protection and It is a new type of building production mode with sustainable development to maximize the value of the whole cycle.

Precast buildings can effectively reduce the amount of wet work on the construction site, reduce labor costs, reduce material waste to a certain extent, and reduce construction noise, dust pollution, construction waste and sewage discharge.
