The advantages and disadvantages of cast-in-place reinforced concrete structure and precast concrete structure are briefly described.

Prefabricated and assembled integral reinforced concrete structure housing system can realize high-quality and large-scale industrial production. Its main features are:

1, the production takes the factory as the core, and a large number of building components are mass-produced in the factory, with high production efficiency.

2. Mould production of building components has improved technological conditions, reduced the impact of personnel changes on quality and improved the quality level.

3. The production is not affected by seasons and weather changes.

4. The field operation is mainly based on assembly, which reduces the field wet operation and labor consumption, and the construction speed is fast.

5. It is easy to realize modularization, standardization and large-scale production.

The idea of industrialization of assembled monolithic reinforced concrete houses developed by our company is to prefabricate horizontal stress components and vertical non-stress components, such as non-load-bearing internal and external partitions, balconies, stairs, floors and beams. , while the vertical stress components are still cast in place, such as constructional columns and shear walls. The connection between all components is cast-in-situ integral connection, which not only ensures the integrity of the structure, but also improves the degree of industrialization of the building, and at the same time conforms to the architectural design concept of "strong column and weak beam", "strong shear and weak bending" and "strong node"; It can be widely used in houses, offices, hospitals, schools, businesses and other general civil buildings. There are different solutions to different structural forms such as brick-concrete structure, frame structure, frame-shear wall structure and shear wall structure.

Zhongshan Kuaileju Housing Prefabrication Co., Ltd. inherited the production experience of prefabricated PC components formerly known as Hong Kong and Macao, organized technical personnel to tackle key scientific and technological problems, and developed technologies and technologies suitable for housing industrialization according to domestic design specifications and construction standards, resulting in many technical achievements in building structural forms, component connection methods, installation tools and construction methods. He has unique experience in process flow design, building component disassembly, mold design and manufacturing, component production and so on. In the prefabricated PC component factory, it extends to the service links such as tool processing, technical training, plant investment analysis, etc., and can provide one-stop and all-round professional services for investors, design units and construction units from multiple angles.

As for how to choose which parts to produce in the factory, the following principles should generally be followed:

1, quality principle. In order to eliminate common quality problems and improve the quality level of buildings, if it is difficult to ensure on-site production, we should consider moving to a factory for manufacturing. Production with standard molds can ensure product quality.

2. Price principle. For the parts with high production cost and price advantage produced by the factory, the factory should be selected for production. Like stairs.

3. The principle of difficulty. For parts that are too difficult to be constructed on site and can be reduced through industrial production, consideration should be given to production in the factory. For example, there are many construction links such as masonry, plastering, heat preservation and decoration in site construction, especially when there are special-shaped bay windows, formwork support is more difficult. In the factory, many processes are concentrated in one mold for production, and the mold can be reused, which reduces the production difficulty; Cantilever components such as balcony are difficult to form, so prefabricated balcony can be used; Bathroom caisson requires accurate hole leaving, complicated construction and high waterproof requirements, so prefabricated caisson or even prefabricated whole bathroom can be used.

4. The principle of progress. Because the factory has good production process conditions and high production efficiency, it is not affected by seasons and weather, which reduces the cross operation of construction. By changing space to gain time, the progress can be obviously accelerated, especially in the cold areas in the north, storage components can be produced in the factory in winter and transported to the site for installation in other seasons, which has a fast construction speed.

5. Environmental principles. The pollution of "three wastes" in traditional construction is serious, and the construction noise often causes contradictions. After being transferred to the factory for chemical production, the site mainly focuses on assembly work, which reduces the pollution and water and electricity consumption in the construction process and is conducive to energy conservation, environmental protection and clean production. Especially in the case of small site, only prefabrication can solve the contradiction of insufficient site and reduce the interference of construction on the surrounding environment.
