Detailed explanation and five advantages of prefabricated building construction process?

Prefabricated buildings are no strangers, especially in recent years, after the emergence of 3D printing technology, prefabricated buildings will become the mainstream of new buildings. As an engineer, you must know the construction process of prefabricated buildings.

Five advantages of prefabricated building technology over traditional building technology;

1. The construction site cancels the external frame and the plastering process of indoor and outdoor walls. The steel bars are uniformly distributed by the factory, the floor bottom formwork is cancelled, and the traditional wooden formwork is replaced by the wall plastic formwork, which can greatly reduce the on-site construction waste.

2.PC components are prefabricated in the factory, transported to the construction site, and hoisted in place with large hoisting machinery. The operator only needs to put the pallet in place and fix it temporarily, which greatly reduces the labor intensity of the operator.

Assembled:

3. The reserved size of doors and windows has been completed in the factory, and the size deviation is completely controllable. The wooden bricks and concrete blocks reserved for indoor doors are also completed in the factory, with accurate positioning, simple on-site installation and easy guarantee of installation quality.

4. The insulation board is sandwiched between two concrete slabs, and there is an effective fire separation between each wallboard, which can achieve Class A fire protection of the system and avoid large-scale fire hazards. The external wall is concrete structure, which has good waterproof and impermeability effect.

5. The internal and external painting is cancelled, and the walls are all concrete walls, which effectively avoids the common quality defects such as wall cracking, hollowing and cracking, and has good flatness. Paint can be painted in advance or the external decorative surface can be constructed or artistic concrete can be used as the decorative surface to avoid the risk of cross-contamination in the construction of the external decorative surface.
