Prefabricated concrete beam-column frame structure
The prefabricated concrete beam column frame structure absorbs the essence of beam column structure, frame structure and hybrid structure, and is guided by the prefabricated structure. The factory standardizes the production of composite beams, composite columns and composite plates. Laminated floor+cast-in-place, floor and beam and column are integrally formed, and villa is built with bridge technology. It takes three steps to build villas, factories and residences. The first step is to produce all kinds of prefabricated parts in the factory, including composite beams, composite columns, composite plates, etc; In the second step, at the project site, the crane and other equipment will lift the beams and columns and use our patented technology to connect the nodes; The third step is to pour concrete together with the joint of beams and columns, so that the whole building can be connected as a whole, with high strength, good seismic resistance, corrosion prevention and fire prevention.
The prefabricated concrete frame beam-column structure is the frame beam-column bearing. Its structural characteristics are: 1. It is a frame structure. 2 The main structural members are beams and columns. 3. The connection of beams and columns is unique. 4. The beams and columns are prefabricated. 5. The installation of beams and columns is fabricated.
The connection mode of beam-column is the most critical part of prefabricated concrete frame beam-column structure, which is also the basic guarantee of structural safety. Through years of research and development and technical research, our company has developed a patented connection method, namely bolt positioning, reinforcement integration and grouting cement. This connection method is through the mutual engagement of embedded parts and accurate positioning; Convenient construction, fast installation and cost saving.
This connection mode has obvious advantages over similar products: 1. Low cost, saving 150 yuan per square meter of construction. 2. In this connection structure, the materials of the connecting members and the internal members of the composite beams and columns are the same, and the material's elasticity and stress resistance are the same, so as to avoid the later cracking of the joint after grouting. 3. The building speed is fast and labor is saved. The overall structure is solid and the structural design is simple. 4. Wall filling materials are easily purchased locally (aerated blocks, unburned bricks, etc.). 5. The house has a large built-in space. L-shaped, T-shaped, I-shaped, ten-shaped and other beam-column structures are adopted, and external corners will not appear around the wall. Our company adopts a patented technology independently developed - invisible beam-column structure. Patent No. 202320091269X (fabricated concrete invisible frame structure) and patent No. 2023200913211 (a fabricated concrete frame connection structure).
Advantages (compared with other building methods):
1、 Fast building speed; Prefabricated components are produced in the factory, and hoisting and splicing operations are carried out on site. The construction and assembly are highly mechanized, without formwork erection, with higher efficiency and greatly shorten the construction period. The main construction of 200-300 square meters can be completed in three days. Faster than cast-in-place frame (traditional cast-in-place frame can only be built once a week)
2、 Low cost and less support: traditional buildings use more people, take a long time, consume a lot of materials, and need a lot of scaffolding. The cost of prefabricated concrete beam-column frame structure is more than 30% lower than that of cast-in-place concrete buildings.
3、 Reduce pollution. Assembled buildings are of great benefit to energy conservation and environmental protection. They can greatly reduce the discharge of construction waste and waste water, reduce the construction noise, reduce the discharge of harmful gases and dust, and reduce on-site construction and management personnel, which is conducive to the healthy and green development of cities in China
4、 Construction safety is guaranteed. Shorter construction time and lower accident rate
5、 All-climate construction; Dry construction, free from the weather, all-weather construction.
6、 Green energy conservation: in the process of use, prefabricated buildings are more green, energy conservation and environmental protection, and the infilled walls are made of lightweight thermal insulation materials for thermal insulation and sound insulation; According to the measurement method of each household, under the same heating temperature, the indoor heat preservation is higher, and the householder can reduce the heating temperature, save heating costs, and reduce the use of energy.
7、 There are a large number of steel structures in the fabricated concrete beam-column structure with good seismic performance, and the seismic effect is more than Level 9, 1.4 times that of the cast-in-place frame.
8、 Concrete with good fire resistance is a mixture of aggregate, cement, water, etc. Because its components are non-combustible materials, it has natural fire resistance. Compared with steel structure room, concrete has high melting point and good fire resistance.
9、 Wide application; Country villas, industrial plants, commercial houses, office buildings, etc
