by PC is the English abbreviation of precast concrete, which is called PC component in the field of residential industrialization.
The cast-in-situ concrete shall meet the needs of the construction site and the cast-in-situ concrete.
Precast concrete units are widely used in construction, transportation, water conservancy and other fields, and play an important role in the national economy.
Xiaobian has recently collected some content related to PC components on the Internet, and will share it with you! It’s a little long.
Please read it slowly! According to the characteristics and performance of components, 1.
Precast floor slab (including precast solid slab, precast hollow slab, precast laminated slab and precast balcony); 2.
Precast beam (including precast solid beam, precast composite beam and precast U-beam); 3.
Prefabricated wall (including prefabricated solid shear wall, prefabricated hollow wall, prefabricated laminated shear wall and prefabricated non bearing wall); 4.
Precast column (including precast solid column and precast hollow column); 5.
Prefabricated stairs (prefabricated stair sections, prefabricated rest platforms); 6.
Other complex special-shaped components (prefabricated bay window, prefabricated exterior wall with bay window, prefabricated corner exterior wall, prefabricated integral kitchen toilet, prefabricated air conditioning board, etc.).
Subdivide according to different process characteristics.
1.
Precast composite floor slab includes precast prestressed composite floor slab, precast truss reinforcement composite floor slab, precast ribbed prestressed composite floor slab, etc; 2.
Precast solid shear wall includes precast reinforced sleeve shear wall, precast restrained mortar anchor shear wall, precast mortar anchor hole indirect lap shear wall, etc; 3.
The prefabricated exterior wall can be divided into prefabricated ordinary exterior wall, prefabricated sandwich insulation exterior wall and so on.
In short, the manifestations of prefabricated components are diverse and can be flexibly adopted according to the characteristics and requirements of the project, which will not be repeated here one by one.
The use of precast floor slab and precast balcony # precast floor slab with typical styles of prefabricated components can reduce the workload of supporting formwork on the construction site, save labor and revolving materials, and has good economy.
It is an important measure for precast concrete buildings to reduce cost, speed up construction period and ensure quality.
Among them, prestressed floor slab can effectively play the role of high-strength materials, It can reduce the section and save steel, which is an important measure of energy conservation and carbon reduction.
The prefabricated floor slab has high production efficiency and fast installation speed, which can create significant economic benefits.
Prefabricated truss reinforced composite floor slab ↑ prefabricated prestressed composite floor slab ↑ prefabricated ribbed prestressed composite floor slab ↑ prefabricated solid floor slab ↑ prefabricated hollow floor slab ↑ prefabricated composite balcony ↑ fully prefabricated balcony ↑ prefabricated beam.
Prefabricated beam is the main horizontal load-bearing component.
It is the same formwork free technology as prefabricated floor slab, which has good economic benefits and broad development space.
Prefabricated prestressed beam ↑ prefabricated composite beam ↑ prefabricated U-shaped hollow beam ↑ double-sided prefabricated composite beam ↑ prefabricated wall there are many walls in the residence.
The use of prefabricated wall can improve the building performance and quality.
From the perspective of the whole life cycle of the building, it can save the maintenance cost during use and reduce the leakage risk of door and window openings, It reduces the fire risk of external wall thermal insulation materials, prolongs the service life of thermal insulation and decoration, cancels the external wall scaffold, improves the construction speed, is conducive to the on-site construction safety management, and has good indirect benefits.
According to the characteristics of domestic houses, prefabricated walls and prefabricated floors will be the main products of industrialized residential components.
