In February 14, 2017, Jiangsu Province Department of housing and urban rural construction, Jiangsu provincial development and Reform Commission, Jiangsu Province Economic and Information Technology Commission, Jiangsu provincial Environmental Protection Bureau, Jiangsu Province Bureau of quality and technical supervision and other five departments jointly issued the "notice" on accelerating the promotion and application of prefabricated wall board prefabricated precast floor in the new building in Jiangsu. As the first in the "three" introduced to promote the application of the policy of the provinces.

 

Purpose of introduction
Implement the spirit of "guidance" to the general office of the State Council on the development of prefabricated construction and the "Jiangsu provincial government" on accelerating the modernization of the construction industry to promote the construction industry to upgrade the file, to speed up the use of prefabricated construction technology, actively and steadily promote the modernization of the construction industry in the province.

Implementation scope
Monomer construction area of more than 20 thousand square meters of new hospitals, hotels, office buildings, as well as more than 5000 square meters of new school buildings;
Newly built commercial housing, apartment, affordable housing;
Single building area of more than 10 thousand square meters of standard factory buildings.

Implementation time
Provincial Construction Industry Modernization demonstration cities (counties, districts) since December 1, 2017, other cities (counties) since July 1, 2018, in the new project to promote the use of "three board". New construction projects are connected to the time limit for construction drawings.

Application requirements
For the concrete structure building, the inner partition board, the prefabricated stair board and the precast laminated floor shall be adopted to encourage the adoption of the prefabricated external wall board;
For steel structure building, should adopt the inner partition board, prefabricated external wall board;
The outer wall of the utility model is characterized in that a prefabricated sandwich thermal insulation wallboard and the like are adopted;

Single building in the mandatory application of the three board total ratio shall not be less than 60%. To encourage residential projects to meet the above requirements, based on the active use of prefabricated balcony, prefabricated panels, prefabricated panels and other prefabricated air conditioning components (components), to improve the rate of prefabricated prefabricated building.

Support policy
The new building external wall with prefabricated sandwich thermal insulation wallboard, the insulation layer and the external wall panel cross-sectional area, can not be included in the project volume rate accounting;
New construction using the identified three board, the collection of new wall materials special fund full refund;
For the three board application projects, according to the rate of prefabricated construction of its monomer construction approved dust emission reduction factor.

Job requirements
One
Throughout the planning and construction, development and reform, by the letter, environmental protection and quality supervision of administrative departments should be combined with local conditions, from the project, planning, design, production, construction, acceptance and other sectors, to establish the "three" application system. The design unit in the design document should be clear about the "three" application, construction drawing review body to strict examination of construction drawing design documents, engineering supervision units should strengthen supervision duties, engineering quality and safety supervision institutions should strengthen the quality of board application projects and safety supervision;

 

Two
All localities should take effective measures, formulate the detailed rules for the implementation of volume rate incentives and other related support policies, and carry out the "three" application, and as to promote the development of prefabricated construction, an important content to realize the modernization of the construction industry;

 

Three
Localities should strengthen the three board to promote the application of supervision. Provincial housing and urban construction department will regularly organize relevant departments to strengthen the supervision and inspection of the application of the three board, to ensure that the three board to promote the application of the work carried out.

 

What are the three boards?
Precast internal and external wall panel
There are two main types of precast wall panels. First, PC wall panels, including single side folding, double folding type, fully prefabricated. Two is the industrialization of finished wall panels, including ALC (autoclaved aerated concrete light wallboard), ceramsite concrete wall panels, etc..

Precast floor
The main types of precast floor slab are precast concrete slab with ribbed floor, truss reinforced concrete composite floor slab, precast concrete hollow floor slab, prefabricated double T plate, etc..

Precast stair
The prefabricated stair board according to the structure can be divided into beam bearing type, bearing wall and wall cantilever type etc.. At present, the prefabricated stair adopts sliding connection type, and the surface of the stairs and the anti slip strip are formed once, and can be used after assembly.

Promote the three board what are the important significance?
In the new building to promote the application of the "three board", to reduce manual work, reduce wet operations, reduce the field operations, improve the quality of the project, improve the construction efficiency has a significant role.
