by From the largest precast building in Central China recently built by China Construction Third Engineering Bureau – the climbing construction platform of Wuhan Zhuankou six village project undertaken by China Construction Third Engineering Bureau Green Investment Co., Ltd.
has been built, and the 14th floor main structure has been completed to realize “building one floor in three days” The comprehensive reconstruction project of six villages in Zhuankou District of Wuhan, which is a key livelihood project in Hubei Province, has a planned total construction area of about 803000 square meters and 29 houses.
After completion, 5681 residents will settle here.
The project is constructed in the way of precast construction.
First, the “parts” such as beams, wallboards, laminated floors, stairs and balconies are produced in the factory, and then transported to the construction site to be assembled like building blocks.
The assembly rate of the project is 56.2%.
Compared with the traditional cast-in-situ construction method, it reduces the wet work on site, reduces dust, reduces construction waste, and effectively reduces leakage, hollowing Crack and other building quality problems, optimize the delivery and hoisting sequence of components, form the flow operation method of “hanging one wall, inspecting one wall and pouring one wall”, optimize the insertion time of small processes, greatly improve the construction efficiency, and introduce the climbing construction platform for safety protection and facade construction The demolition shall be carried out on the ground to avoid potential safety hazards caused by high-altitude disintegration.
Each floor can be lifted and lowered at any time in less than 1 minute, so as to reduce the intersection between climbing frame construction and internal wall operation, which is conducive to interspersed operation.
The media focuses on the 29 buildings of Xinhua news agency, people’s daily, CCTV news, China People’s government network, and the 24-hour rotation operation project is constructed at the same time.
At present, the bimonthly output value of April and may exceeds 200 million yuan, The project is speeding up with the construction speed of “three days and one floor”.
