Advantages and disadvantages of precast housing
For the design of precast building external hanging boards, some flat floor boards have water stop rubber strips, while some external hanging boards 200 higher than the floor board have no water stop rubber strips.
Precast houses can be produced directly in the factory, and the relevant precast components can be transported to the construction site for assembly.
Disadvantages of precast house: because the precast building is a concrete structure, it is required to be as accurate as possible in size and position when reserving and embedding.
As a green construction technology, precast house is a new concept and technology of architecture, and it is still in the stage of gradual growth.
Click the blue word to pay attention to the advantages of our precast house: its thermal insulation performance is better than the external thermal insulation or internal thermal insulation of the external wall of traditional buildings, and it also solves the phenomenon of falling off of the external wall decoration caused by the external thermal insulation of traditional buildings.
It cannot be built as high as the traditional buildings want, and the floor height will be limited.
There will be some difficulties in the production of components, and the technology is not particularly mature.
The biggest defect is that the seismic effect is slightly weak, because the stiffness is weaker than the traditional structure, so the impact resistance is relatively poor.
If there is no water stop rubber strip, although the weather resistant adhesive is used to treat the outer joint, there is still a possibility of leakage.
The engineering cost of precast buildings is much higher than that of traditional buildings.
Moreover, during the construction process, the materials of cement, yellow sand and reinforcement are reduced, and the construction waste of on-site construction is reduced, which can play the role of energy conservation and environmental protection.
It adopts the latest cold pressed light steel structure and various parts of various light material composite houses, so that it has excellent thermal insulation, sound insulation, fire and insect prevention, energy saving and seismic performance.
It is recommended that all external hanging plates should have water stop rubber.

Otherwise, it is necessary to re slot and hole, which will increase the construction difficulty and even affect the structure.
Without the influence of climate and temperature change, the quality can be effectively controlled.
Just like building blocks, it can shorten the construction period, reduce the on-site construction process, and shorten the cost of manpower and material resources.
Precast house refers to the house assembled on site by factory prefabrication.
