Why are precast buildings popular? You will know after reading this article!
Therefore, the country vigorously promotes precast buildings.
So, what is precast buildings? How are precast buildings produced? How is the site constructed? If you want to know the answer, let’s have a look.
If you don’t learn, you will be out! Engineering people must read! ► The most comprehensive experience sharing of precast building projects in history! 6 cases+nearly 100 site maps, pure dry goods! ► After seeing so many European, American and Japanese construction sites, I was shocked by this domestic precast construction project! ► A wave of top German precast villas is coming…
Source: Alliance of Real Estate Managers (ID: dichan360) Intern Editor: Cheng Jie, you don’t know about precast buildings, precast buildings are famous for environmental protection, energy conservation and fast construction.
Operators only need to put the handrails in place and fix them temporarily, which greatly reduces the labor intensity of operators.
The case of excellent precast buildings is 80 years ahead of China, or 80 years later, There is no such precast super high-rise landmark in China…
the forefront of architectural innovation! Learn about precast buildings here: ► The State Council issues heavy documents! Deploy 7 major tasks to promote the sustainable and healthy development of the construction industry! ► The State Council is pushing for precast buildings.
First, why are precast buildings popular? █ The controllable construction process of precast buildings has realized the complete control of the whole construction process ▲ The above figure shows the transformation of the precast buildings in Country Garden ▼ The green construction has changed the backward production mode of the traditional construction industry ▼ The “five sections and one environmental protection” has been truly realized and the green and low-carbon construction concept has been fully practiced █ Low consumption and high efficiency, Construction period reduction Comparison of resource consumption in the construction stage between the building industrialization method and the traditional method: (take the 30 storey hardbound residential building as an example) ▼ Comparison of resource consumption in the construction stage between the building industrialization method and the traditional method █ Comparison of construction site Scaffolding was canceled in the construction site, indoor and external wall plastering processes were canceled, steel bars were uniformly distributed by the factory, floor bottom formwork was canceled, and traditional wood formwork was replaced by plastic wall formwork, Construction waste on site can be greatly reduced.

▲ The world’s first precast 7-star hotel Conclusion The popularity of precast buildings is a general trend; Assembled building started late in China, but it has been strongly supported by the government.
█ The construction accuracy comparison of the reserved size of the door and window openings has been completed in the factory, and the size deviation is completely controllable.
The assembly type building process section █ Mechanical fabrication of reinforcement cage in PC, █ PC steel mold fabrication, █ Placing reinforcement, various embedded parts, █ Pouring concrete, █ Concrete steam curing, steam curing, 6-9 hours, After the concrete strength reaches 70%, the formwork shall be released and the concrete shall be put into storage after passing the inspection, Loading and transporting to the construction site according to the progress of the construction site Dynamic picture of component production ▲ Factory fully automatic manipulator formwork erection ▲ Concrete pouring of laminated inner plate ▲ Vibrating and plastering of laminated inner plate concrete ▲ Entering the curing room after inspection and verification ▲ Flipping laminated outer plate ▲ Hoisting and stacking of laminated plate ▲ Precast double-sided laminated plate █ Installing the outer wall panel (precast insulation wall) █ Installation of wallboard connectors, treatment of slab joints █ Installation of laminated beams █ Installation of interior wallboards █ Column, shear wall reinforcement binding █ Installation of formwork in elevator shaft █ Shear wall, column formwork installation █ Wall, column pouring concrete █ Wall column formwork removal, wall column formwork removal, floor support erection Installation of superimposed floor █ Hoisting of stair flight █ Installation of safety protection measures on working face █ Installation of crack resistant reinforcement at the floor abutting seam █ Enter the next floor process to enter the structure construction of the previous floor, remove the railing, and hoist the exterior wall panel.
The external wall is of concrete structure, with good waterproof and impermeable effect.

It is the outlet of the engineering construction industry.

█ The internal and external painting is canceled in the quality comparison of the finishing.
3、 Assembled factory and construction reality █ Concrete prefabrication (PC) █ Precast thermal insulation wall █ Finished exterior wall panel █ Reverse printing process of exterior wall veneer █ Finished composite panel █ Real scene of prefabrication workshop ▼ 13 storey residential building construction site, which only takes 82 days to complete, not only improves the construction speed, but also greatly improves the building quality.
Besides, the thermal insulation effect is good, and the durability of the thermal insulation layer is good.
The comparison (summary) between the assembly type and traditional construction of the fully decorated finished house.
The walls are all concrete walls, effectively avoiding common wall quality problems such as cracks, hollowing, cracks, and good flatness.
I hope that peers can seize the opportunity of China’s construction mode transformation to make enterprises bigger and stronger…
The wood bricks and concrete blocks that need to be reserved for indoor doors are also completed in the factory, with accurate positioning, simple on-site installation and easy installation quality assurance.
█ Fire performance comparison The insulation board is sandwiched between two layers of concrete slabs, and the effective fire separation between each wall panel can achieve the system fire protection level A, to avoid large-scale fire hazards.
Paint can be applied in advance or the exterior finishing layer can be constructed or artistic concrete can be used as the finishing layer to avoid the risk of cross contamination during the construction of the exterior finishing surface.
PC components are precast in the factory, and lifted in place by large hoisting machinery after being transported to the construction site.
█ Fine decoration comparison The pipeline is embedded in place in the factory, and there is no need for post slotting on the site.
