Precast concrete is a modern and versatile building material suitable for any type of construction, from private villas to affordable housing, commercial centers, industrial buildings, or public spaces. Preforms can be made into almost any shape and size. Basically, all structural entities of a building can be constructed with precast concrete. Various wall panels, hanging panels, facades, partition walls, floor slabs in residential buildings, as well as concrete piles used in foundations, beams, columns in structural frames, and even special components such as balconies and stairs can be prefabricated.
1. Precast Laminate Floors:
Including prefabricated prestressed composite floor, prefabricated truss reinforced composite floor, prefabricated ribbed prestressed composite floor (PK board), etc.
2. Precast solid shear walls:
Including prefabricated reinforced sleeve shear wall, prefabricated constrained grout anchor shear wall, prefabricated grout anchor hole indirect lap shear wall, etc.;
3. Prefabricated facades:
From the structure, it can be divided into the prefabricated ordinary outer wall, prefabricated sandwich insulation outer wall, and so on.
In a word, the expressions of prefabricated components are various, which can be flexibly adopted according to the characteristics and requirements of the project.
4. Prefabricated Floors:
The use of prefabricated floor slabs can reduce the workload of supporting formwork on the construction site, save labor and turnover materials, and has good economics. It is an important measure for prefabricated concrete buildings to reduce cost, speed up the construction period, and ensure quality. Among them, prestressed floor slabs can effectively play The role of high-strength materials that can reduce the section and save steel, which is an important measure for energy saving and carbon reduction. The production efficiency of prefabricated floor slabs is high, the installation speed is fast, and it can create significant economic benefits.
▲ Prefabricated truss reinforced composite floor
▲ Prefabricated prestressed laminated floor
▲ Prefabricated ribbed prestressed laminated floor
▲ Prefabricated solid floor
▲ Prefabricated hollow floor slab
5. Precast beams:
The prefabricated beam is the main horizontal load-bearing member, and the same as the prefabricated floor slab is a formwork-free technology, which has good economic benefits and broad development space.
▲ Prefabricated prestressed beams
▲ Prefabricated composite beams
▲ Prefabricated U-shaped hollow beam
▲ The double-sided prefabricated composite beam
6. prefab wall：
There are many walls in residential buildings, and the use of prefabricated walls can improve building performance and quality. From the perspective of the entire life cycle of the building, it can save maintenance costs during use, reduce the risk of leakage from doors and windows, and reduce external wall insulation materials. It increases the fire hazard, prolongs the life of thermal insulation and decoration, can cancel the external wall scaffolding, improve the construction speed, is conducive to the safety management of on-site construction, and has good indirect benefits. According to the characteristics of domestic residences, prefabricated walls and prefabricated floors will be industrialized. The main products of residential components.
▲ Prefabricated solid shear wall
▲ Prefabricated hollow walls
▲ Prefabricated Shear Wall (Double Skin Wall)
▲ Prefabricated sandwich thermal insulation exterior wall
▲ Prefabricated thermal insulation and decoration integrated exterior wall
▲ Hong Kong construction method exterior wall hanging board
▲ Japanese construction method exterior wall hanging board
7. prefabricated column：
▲ Prefabricated solid column
▲ Prefabricated hollow column
8. prefab stairs：
▲ Prefab Staircase
▲ Stair finished product protection
9. Other complex special-shaped components
(Prefabricated bay windows, prefabricated exterior walls with bay windows, prefabricated corner exterior walls, prefabricated integrated kitchens and bathrooms, prefabricated air-conditioning panels, etc.)
Although the cost of prefabricated complex special-shaped components is not low, it is often due to the difficulty of on-site construction and the difficulty in guaranteeing the quality. Under the premise of a certain amount, it can be transferred to the factory for prefabrication, which can not only ensure the quality, and improve the speed of on-site construction, but also improve the construction speed. There are also certain economic advantages to mass production.
▲ Prefabricated thermal insulation bay window
▲ Prefabricated exterior wall with bay window
▲ Prefabricated stacked balcony
▲ Fully prefabricated balcony
▲ Prefabricated corner exterior wall
▲ Prefabricated whole bathroom
