Flat End Socket

Moreover, the thermal insulation effect is good, the durability of the thermal insulation layer is good, the outer wall is of concrete structure, and the waterproof and impermeability effect is good.

PC components are precast in the factory, transported to the construction site and hoisted in place by large lifting machinery.

4.

Excellent precast building cases lead China for 80 years, or 80 years later, There is no such precast super high-rise landmark in China ▲ The world’s first precast seven-star hotel Conclusion The popularization of precast buildings is the trend of the times; Precast construction started relatively late in China, but it has received strong support from the government.

3、 Assembled factory and construction reality █ Concrete prefabrication (PC) █ Precast thermal insulation wall █ Finished exterior wall panel █ Reverse painting process █ Finished laminated panel █ Realistic scene of prefabrication workshop █ Assembled building construction site ▲ 13-storey residence, completed in only 82 days, not only improves the construction speed, but also greatly improves the building quality.

█ Construction accuracy comparison The reserved size of door and window openings has been completed in the factory, and the size deviation is completely controllable.

█ Fire protection performance comparison The insulation board is sandwiched between two layers of concrete slabs, and the effective fire separation between each wall panel can reach the system fire protection level A to avoid large area fire hazards.

I hope that peers can seize the opportunity of China’s construction mode transformation and make the enterprise bigger and stronger The forefront of architectural innovation! Learn about precast buildings here: ► The State Council issued a massive document! Deploy 7 major tasks to promote the sustainable and healthy development of the construction industry! ► The State Council is pushing for precast buildings, and it will go out without learning! Engineering personnel must read! ► Experience sharing of the most comprehensive precast construction project in history! 6 cases+nearly 100 scene pictures, pure dry goods! ► After seeing so many construction sites in Europe, America and Japan, I was shocked by this precast construction project in China! ► A wave of top precast villas in Germany came (100 large high-definition pictures) ► Click on the lower left corner“

Source: Intern editor of the Alliance of Real Estate Managers (ID: dichan360): Cheng Jie, the precast building you don’t know is famous for its environmental protection, energy conservation and fast construction speed, so the country vigorously promotes the precast building, so what is the precast building? How are precast buildings produced? How is the site constructed? If you want to know the answer, let’s have a look.

The precast construction process █ Mechanical production of the reinforcement cage in the PC █ PC steel mold production █ Placing the reinforcement, various embedded parts █ Pouring concrete █ Steam curing of concrete 6-9 hours, After the concrete strength reaches 70%, release █ and put it into storage after passing the inspection, According to the progress of the construction site, the parts are loaded and transported to the construction site according to the production dynamic diagram ▲ the factory’s fully automatic manipulator forms the formwork ▲ the concrete pouring of the laminated inner plate ▲ the concrete vibrating and evenly plastering of the laminated inner plate ▲ the maintenance room after inspection and verification ▲ the folded outer plate ▲ the laminated plate is lifted and stacked ▲ the precast double-sided laminated plate █ the installation of the outer wall plate (precast insulation wall) █ the installation of the wall plate connectors Slab joint processing █ Installation of laminated beam █ Installation of inner wall plate █ Column, shear wall reinforcement binding █ Installation of formwork in elevator hoistway █ Shear wall, column formwork installation █ Wall, column pouring concrete █ Wall column formwork removal Wall column formwork removal, floor support erection, installation of laminated floor █ Hoisting of stair flight █ Installation of safety protection measures on working face █ Installation of anti-crack reinforcement at floor joint █ Enter the next floor process and enter the structure construction of the previous floor, Remove the handrail and lift the outer wall panel.

First, why are precast buildings popular? █ Controllable construction process of precast buildings has achieved complete control of the whole construction process ▲ The picture above shows the change of the process of the precast buildings in Country Garden █ Green construction changes the backward production mode of the traditional construction industry ▼ To truly realize the “five saving and one environmental protection” and fully implement the green and low-carbon construction concept █ Low consumption and high efficiency, Comparison of resource consumption in the construction stage between the construction industrialization mode and the traditional construction mode with shorter construction period: (taking the 30-storey hardbound house as an example) ▼ Comparison of resource consumption in the construction industrialization mode and the traditional construction mode █ Comparison of construction site The scaffolding is canceled in the construction site, the indoor and external plastering processes are canceled, the reinforcement is uniformly distributed by the factory, the floor bottom formwork is canceled, and the wall plastic formwork replaces the traditional wood formwork, The construction waste on site can be greatly reduced.

The paint can be applied in advance or the exterior finish layer can be constructed or the artistic concrete can be used as the finish layer to avoid the risk of cross contamination during the construction of the exterior finish.

The comparison between precast and traditional construction of the finished product house of the finished product of the finished product of the part and chemical engineering (summary) II.

At the same time, the flatness is good.

█ The internal and external painting is canceled for the quality comparison of the finish.

It is the outlet of the engineering construction industry.

█ Fine decoration comparison The pipeline is embedded in place in the factory, and there is no need for rear slotting on the site.

The operators only need to hold the plates in place and temporarily fix them, which greatly reduces the labor intensity of the operators.

Wooden bricks and concrete blocks to be reserved for indoor doors are also completed in the factory, with accurate positioning, simple on-site installation and easy installation quality assurance.

The walls are all concrete walls, which can effectively avoid cracks, hollowing, cracks and other common quality defects of the wall.
