The project is located in the east of Qingpu new town and belongs to the planning scope of the large community of Xincheng No.
1 station in Qingpu District, Shanghai.
The total land area of the project is 27938.2 square meters, including 8 16-18 storey precast houses (including 8# building podium for community and business), an underground garage, a garbage house and a substation, with a total construction area of 83218.35 square meters, The aboveground building area is 56917.49 square meters (including 55873.69 square meters of capacity area), and the underground building area is 26300.86 square meters.
100% of the construction area of the project shall be precast buildings, and the assembly rate of single precast concrete shall be ≥ 30%.
As a green demonstration project, the project has adopted a number of advanced green and energy-saving technologies and achieved good results.
Project information project name: ordinary commercial housing project in plot 63a-03a of Qingpu new town construction unit: Shanghai Baoyue Real Estate Development Co., Ltd.
construction location: the base extends to Guihua fifth road in the East, planned plot in the West and Puhe road in the north, North to Guihua 4th Road building type: residential community design / completion: 2014 / total construction area under construction: 83218.35m2 building height / floors: 59.15m/18f floor area ratio: 2.0 design unit: Huajian Group East China urban architectural design and Research Institute deepening design unit: Baoye Group Shanghai Architectural Industrialization Research Institute component production unit: construction unit of Shanghai Baoyue residential industry Co., Ltd : Zhejiang Baoye housing industrialization Co., Ltd.
▲ plot plan ▲ general plan [Architecture Specialty] the number of residential buildings in the community is mainly 16 ~ 18 floors, and the standard floor height is 2.95M.
The house type is mainly four households with one elevator and two households with one elevator.
Each unit is equipped with two elevators and one evacuation staircase.
The underground floor is for motor vehicle and non motor vehicle garage and equipment room.
The design of residential house type is based on standardization and modularization, and the design principle is variable house type.
The vertical components below the third floor of the residence are cast-in-situ, the roof of the top floor is cast-in-situ, and the other floors are precast.
The facade modeling style is simple and lively, with the characteristics of industrialized architecture.

Standardized modular design project design forms standardized functional modules around the standard module series based on industrial buildings, and designs standard room bay module, standard door and window module, standard door and window opening size, and standard traffic core module, Standard kitchen and bathroom layout modules, and these standardized building functional modules are combined into standard residential units.
The dimensions of each functional module are shown in the table below.
Table: Room Type Standardization ▲ standardized stair components (left) and standardized balcony components (right) according to the standardized modules, and then further split the standardized structural components to form standardized stair components, standardized air conditioning board components and standardized balcony components, greatly reducing the number of structural components, It provides the basis for large-scale production of buildings, significantly improves the production efficiency of components and fittings, effectively reduces material waste, saves resources, saves energy and reduces consumption.

Realize the integration of civil engineering and decoration based on precast buildings, so as to effectively save resources (energy, land, water and materials), protect the environment, reduce pollution, provide people with healthy, practical and efficient use space, and create a green two-star building in harmony with nature, The project replaces the traditional discrete decoration with the integrated design of building decoration, and replaces the labor-intensive extensive and non-standard individual handicraft production with large-scale and standardized industrial production, so as to improve the safety, beauty, health, environmental protection and other architectural performance of the project decoration.
In the scheme design stage, it is fully considered that the fine decoration and civil engineering design shall be carried out simultaneously, and the civil engineering and decoration disciplines shall coordinate and cooperate with each other.
In the construction drawing stage, the integration of various types of work shall be done well, the reservation of electromechanical pipelines, points and equipment holes shall be indicated in the construction drawing, and marked one by one in the component deepening drawing to guide the industrialized production of structural components.
Do not destroy and dismantle the existing building components and facilities, avoid the demolition, destruction and waste of secondary decoration, and fundamentally save building materials and construction costs.
▲ electromechanical point map of precast building [structure discipline] 1 Overview of precast structure system all residential units in this block adopt precast shear wall structure system.
The main precast components include laminated wall panels, fully precast shear walls, laminated floors, laminated beams, precast balconies, precast air conditioning panels and precast stairs; The prefabrication rate, external wall area rate and precast structure system adopted by each monomer are shown in the table below.
The prefabrication rate of each monomer is greater than 30%, which meets the requirements of corresponding land transfer documents.
According to the volume statistics of various types of precast components in the 4# building monomer, the prefabrication rate of the monomer is 31.2%.
Table: statistical table of monomer prefabrication rate: statistical table of proportion of precast components in monomer prefabrication rate 2 Structural system 1) double sided superimposed shear wall structure double sided superimposed shear wall structure refers to the shear wall structure formed by superimposed wall panels and superimposed floors, supplemented by necessary cast-in-situ concrete shear walls, edge members, beams and plates.
The laminated wallboard is made of two layers of precast wallboard and truss reinforcement of inner and outer leaves..
