According to the requirements of the document, since 2018, all commercial housing projects with new land supply will be constructed with prefabricated technology, and the prefabricated assembly rate of single building will not be less than 50% in principle
.
You may not have a special understanding of the prefabricated assembly rate of single building agreed in the document
.
Tim’s suggestions are as follows: 1
.
In the structure, the integrity of component connection should be ensured (the connection methods between plates mainly include welding, bolt connection and integral connection of post cast concrete)
.
In addition, the external wall and the internal wall near the water using prefabricated construction of goods should also be careful to buy
.
In terms of waterproof structure, it is necessary to properly solve the waterproof problems of exterior wall panel joints, as well as the thermal treatment of floor joints and corners
.
because of the use of standardized design, factory production, assembly construction, information management, intelligent application, it is the representative of modern industrial production mode
.
In accordance with the requirements of promoting supply side structural reform and new urbanization, the government vigorously supports the development of prefabricated buildings and promotes the adjustment and upgrading of industrial structure
.
Based on the above analysis, in order to purchase more easily and reduce the trouble of subsequent rights protection, Mr
.
First of all, let’s take a look at the notice on further promoting the development of prefabricated buildings issued by the general office of Changsha Municipal People’s Government on December 11, 2017
.
Tim will interpret the document in detail for your reference
.
Prefabricated building mainly includes prefabricated concrete structure, steel structure, wood structure, etc

Pay attention to the implementation position and assembly rate of prefabricated building: on the premise of not breaking through the existing policy, It is suggested that the commercial houses with vertical members (shear walls, frame columns, etc.) and horizontal members (frame beams, etc.) adopting prefabricated construction should be purchased carefully
.
Key words summary: carefully buy: prefabricated building involving external wall, frame column, frame beam, shear wall, toilet and balcony near water; can buy: prefabricated building of floor, staircase and non toilet partition
.
Recently, the hot real estate in Changsha (Xinli, Meixi left bank, Greenland, Luyun international, etc.) have burst out, using prefabricated buildings
.
The document specifies the construction task, project implementation, project supervision and policy support of prefabricated buildings

As a vertical traffic component, the function of staircase is less affected by the construction quality of prefabricated building, so it can be used in prefabricated building
.
In the same way, the horizontal stressed components (frame beams, etc.) should not be prefabricated building; second, whether the external infill wall is prefabricated: the construction quality of the joints of the external infill wall is difficult to ensure the waterproof requirements, and the water seepage problem of the external wall of the prefabricated building has been plagued for a long time and is difficult to solve
.
The assembly rate of the above components is calculated according to the proportion of prefabricated buildings, and the same assembly rate has different component combinations
.
Therefore, the external infill wall should not be prefabricated; third, whether the internal infill wall (water facing parts, pipe wells, etc.) is prefabricated: the seepage problem of the internal infill wall near the water is similar to that of the external infill wall, so the prefabricated building should not be used in the toilet, balcony and other water facing parts
.
The hot spots in Changsha, such as Meixi lake, Yanghu lake and Binjiang, are all in the key areas of the document

Dad Tim reminds us that we must pay attention to the administrative scope of commercial housing before buying a house
.
Based on the current situation, Tim reminded the following points: first, whether the vertical (horizontal) stress components are fabricated: in view of the current construction level, the construction quality of the vertical load-bearing component connection node is difficult to meet the theoretical requirements, and the actual seismic performance is difficult to guarantee, so the vertical components should not be fabricated buildings
.
Pay attention to the land supply conditions of commercial housing: before purchasing a house, it is necessary to verify the land supply conditions of the commercial housing plot, and whether it is clearly required to implement and assemble according to the prefabricated building; 2
.
In addition to the above parts, other internal infill walls can be fabricated
.
01 prefabricated assembly forms include vertical stress components (such as shear walls, frame columns, etc.), horizontal stress components (such as frame beams, etc.), and other maintenance or filling components (such as internal and external infilled walls, staircases, structural plates, etc.)

In addition, due to the large number of openings and irregular size, the prefabricated construction is not suitable for the pipeline well
