1、 The Zhonghai Ludan Mingyuan project, which is “planning layout and exploring new construction methods”, is the first project in Shenzhen to use PC component columns.

The Project Department optimizes the construction scheme, organizes emergency special meetings overnight, and discusses with Party A, the designer, and the aluminum mold manufacturer.

In terms of organizational structure and staffing, the Project Department has added PC professional engineers; In combination with the actual situation on site and the interpenetration of the installation process, two aluminum mold installation teams are arranged for parallel construction.

The precast building has obvious advantages in functional characteristics, structural system, building performance and project cost.

From the determination of the component type, to the component disassembly, installation and connection embedment, transportation route selection, to the preparation before hoisting, the Project Department has considered in advance and controlled accurately.

For example, when the external scaffold is cantilevered, the traditional method is to embed the wall fasteners on the board surface, but after the PC component is installed, the wall fasteners cannot be fixed.

In the process of assembly construction, many difficulties are encountered.

The control of hoisting quality is the key step and core content of assembling integral structure engineering, and the accuracy of construction survey is the key point of control.

In addition, the project technical team has carried out no less than 20 special discussions and meetings, reviewed professional drawings intensively, put forward more than 100 optimization suggestions, and optimized the design with the owner and the design institute; The schemes of Aluminum Mold Installation Method Statement and PC Component Installation Method Statement have been prepared.

No mistake^_^ It’s him – Zhonghai Ludan Mingyuan.

At present, the factory has been built to the 22nd floor, 1360 pieces of components have been installed, and 1650 cubic meters of concrete have been hoisted.

The demolition and transformation project of commercial housing led by the Shenzhen Municipal Government is a popular project with a total floor area of 260000 square meters.

The project department also broke down the construction process to form independent flow construction of 8 and 9 buildings.

From the production, transportation and hoisting of industrial components, to the installation of on-site reinforcement and formwork, mechanical and electrical embedment and concrete pouring, each process is closely linked.

On the one hand, the special working group strengthened learning, consulted experts, and went to Hong Kong and other places to observe and learn.

(It’s really amazing!) With excellent professional level and indomitable spirit of innovation, the project department has solved one obstacle after another.

The overall assembly of components shall be very tight, otherwise the accumulated error will lead to the failure of subsequent components to be hoisted in place or installed normally.

The largest single weight of the small braided PC component is 7.45 tons, 4.566 meters long and 3.13 meters high, posing great challenges to the hoisting equipment and construction.

Fabricated components shall be produced at least half a month ahead of the project schedule to meet the site construction requirements.

They are the highest precast residential buildings in China at present and are constructed by Guangdong Branch of China Construction Fifth Engineering Bureau.

At present, 8 # building has been constructed to the 24th floor structure.

Small cast construction is the use of factory precast components and accessories, and mechanical assembly at the construction site to form a building, which is an important part of building industrialization.

The new form of concrete+aluminum mold+PC is adopted in the project.

（2） Refined construction quality.

According to the characteristics of assembly construction, the project department weaves a “resource assembly network”.

The project department uses Internet+BIM technology to provide support for informatization construction.

The Project Department plans to apply for a national patent for this process.

3、 In the early stage of technical planning for “innovation is difficult to break, and new technology is condensed”, the Project Department established a PC project research team and a project implementation team.

The project department uses BIM technology to simulate the whole process of animation video construction, check the internal collision of components, as well as the collision between components and the reserved and embedded parts on the construction site, ensure the efficiency and quality of component installation on the construction site, and establish a traceability information record of PC component installation and maintenance.

The construction team went to PC manufacturers for several times to learn skills, and 1:1 simulated installation and drilling on the spot.

2、 “Scientific implementation of policies and preparation of resource network” (I) Technology management is pre positioned.

The concrete products of building “parts” are processed and produced in the factory, transported to the construction site, assembled in the building frame, and perfectly assembled with the building frame through steel bar welding and concrete pouring, Realize “building blocks” to build houses.

Up to now, the Project Department has installed a total of 1610 single precast components.

Since August 12, 2015, when the office area and living area have not been built on the project site, on September 6, the basement of the commercial podium has all rushed out of plus or minus zero five days in advance; On September 18, the capping node of the commercial podium was completed 12 days in advance.

Building 8 # and Building 9 # are cast buildings with structural heights of 147m and 124m respectively.

（3） The processes are closely interwoven.

Finally, it is decided that the wall fasteners are buried at the bottom of the beam when the precast components are made, and the aluminum mold is optimized for the reserved holes, which solves the problem that the external scaffold wall fasteners cannot be embedded.
