on winning the third prize of Shanghai key product quality breakthrough achievement in 2021 for “tackling key problems in the quality of concrete MOCA block precast wall”.
Under this policy background, wall internal insulation, wall self insulation and external insulation decorative composite board will usher in a new round of development opportunities.
The total investment of the new project of supporting primary school in plot a6-01 of supporting living base in zhangjiangnan District of Shanghai Pudong second Central Primary School (Shenjiang campus): 132.35 million yuan.
Construction process innovation.
The land area is 21894.6 ㎡, with a total construction area of 20900 ㎡, including 18000 ㎡ above ground construction area and 2900 ㎡ underground construction area.
The land area is 21894.6 ㎡, with a total construction area of 20900 ㎡, including 18000 ㎡ above ground construction area and 2900 ㎡ underground construction area.
The project started in October 2018 and lasted more than 400 days.
Since the thermal insulation MOCA precast wall was listed in the unified technical regulations on the application of external wall thermal insulation system and materials in Shanghai, the external wall thermal insulation structure integration (concrete thermal insulation MOCA block) Application of thermal insulation mold block in educational buildings — Construction Technology of external wall thermal insulation structure integration (thermal insulation mold block) of Shanghai Fengxian Wuqiao primary school application of thermal insulation mold block in educational buildings — Shanghai Fengxian Xiaotang primary school..
After mortise stacking, lightweight aggregate grouting is used.
The unit weight of the block is 900-950kg / m ³。 The thermal insulation material is placed inside the block to form a complete whole with the block.
After the wall is built, it is protected by the concrete material of the block.
539, which published the catalogue of materials prohibited or restricted from production and use in construction projects in Shanghai (the fifth batch).
The external enclosure structure of the project adopts thermal insulation mold block, which places the thermal insulation material inside the block to form a complete whole with the block.
The production process is innovative.
In previous reviews, I congratulated Shanghai MOCA Construction Engineering Technology Development Co., Ltd.
The production process is innovative.
Its service life is equal to the service life of the wall and even the building, which improves the integrity and safety of the wall.
In addition, there is a 200m track playground and grandstand, basketball court, volleyball court, wind and rain playground, etc.
It is required to strictly implement the projects that fail to pass the review and filing of construction drawing design documents before November 1, 2020 and the projects that have not started the construction of wall energy-saving works before December 31, 2020.
The wall forms a network structure, improves the overall stiffness of the wall, and effectively solves the problems of “crack, seepage, leakage and thermal insulation” of ordinary blocks.
After the wall is built, it is protected by the concrete material of the block, and its service life is equal to the service life of the wall and even the building, so as to avoid the falling off of the external wall brick and coating, The integrity and safety of the wall are improved.
The supporting technology is mature and the technical specifications are perfect, forming a complete set of systems from architectural design specifications to construction quality acceptance, which can successfully solve the cold and hot bridge problems of beams, columns, plates and other walls, meet the requirements of building energy conservation, realize the integration of wall self insulation, and comprehensively improve the comprehensive energy-saving effect and comprehensive economic benefits of the whole wall.
On October 13, 2020, Shanghai Municipal Commission of housing and urban rural development issued Hu Jian Cai [2020] No.
Construction content: build a new teaching main building with one underground floor and four above ground floors (including classroom building, experimental building, administration and reading building, restaurant and multimedia building), as well as single-layer gatekeeper, power transformation and distribution room, garbage room and other buildings.
The traditional mortar masonry process is changed.
The concrete self thermal insulation die block is made of cement and sand as the main raw materials, with built-in thermal insulation materials and special process.
