Cast-free concrete floor deck is a new type of building material, which has many advantages, such as fast construction speed, reliable quality, good seismic performance, etc., and is widely used in high-rise buildings, bridges, tunnels and other fields. This article will introduce in detail the characteristics, application range, construction methods and comparison with other materials of cast-free concrete floor decks, and analyze their advantages and disadvantages.
First, the characteristics of the concrete floor deck without pouring.
1.The construction speed is fast.
The advanced production technology and equipment are used in the production process of the cast-free concrete floor deck, which greatly shortens the production cycle and improves the construction efficiency. At the same time, during the construction process, there is no need to pour concrete, which further shortens the construction time.
2.Reliable quality.
The cast-free concrete floor deck is made of high-strength materials with excellent mechanical properties and durability. In the construction process, due to its stable structure, it is not easy to deform, crack and other problems, so as to ensure the quality of construction.
3.Good seismic performance.
The cast-free concrete floor deck has good seismic performance and can resist the impact of natural disasters such as **. In harsh environments such as **, it can maintain the stability of the building.
Second, the application range of non-pouring concrete floor deck.
1.High-rise buildings.
In high-rise buildings, due to the high floor height, the traditional concrete pouring method is difficult to meet the construction requirements. Due to its advantages of fast construction speed and reliable quality, the cast-free concrete floor deck is widely used in the floor slabs, walls and other parts of high-rise buildings.
2.Bridge.
In bridge construction, due to the large span of the bridge, the traditional concrete pouring method is difficult to meet the construction requirements. The cast-free concrete floor deck has the advantages of stable structure and good seismic performance, and is widely used in the bridge deck, beam body and other parts of the bridge.
3.Tunnel.
In tunnel construction, the traditional concrete pouring method is difficult to meet the construction requirements due to the narrow tunnel space. The cast-free concrete floor deck has the advantages of fast construction speed and reliable quality, and is widely used in the roof and side walls of tunnels.
Third, the construction method of pouring concrete floor deck.
1.Preparation stage.
Before construction, the construction site needs to be cleaned to ensure that the site is flat and clean. At the same time, according to the design requirements, the cast-free concrete floor deck is processed and manufactured.
2.Installation phase.
During the installation process, the cast-free concrete floor deck needs to be installed layer by layer in order according to the design requirements. During the installation process, it is necessary to pay attention to ensure that its flatness, verticality and other parameters meet the design requirements. At the same time, it is necessary to ensure the robustness of the individual connections.
3.Acceptance phase.
After the completion of construction, acceptance work is required. The acceptance work mainly includes the inspection of the flatness, verticality, and firmness of the connecting parts of the concrete-free floor deck. At the same time, it is necessary to check and check the relevant records in the construction process to ensure that the construction quality meets the design requirements.
4. Comparison with other materials.
1.Comparison with conventional concrete.
In the construction process, traditional concrete needs to be poured and cured many times to meet the design requirements, while the cast-free concrete floor deck does not need to be concreted, which greatly shortens the construction time and improves the construction efficiency and quality stability. In addition, traditional concrete is susceptible to cracking and other problems due to the influence of weather and other factors during the construction process, while the cast-free concrete floor deck has excellent durability and stability, which can resist the impact of natural disasters and maintain the stability of the building. Therefore, the cast-free concrete floor deck has greater advantages than traditional concrete in terms of construction efficiency and construction quality.
2.Comparison with other new materials.
In addition to the pouring of concrete floor slabs, there are other new building materials, such as steel structures and prefabricated building structures. These materials have their own characteristics and advantages, but compared with the pouring of concrete floor deck, there are still some deficiencies, such as, the steel structure needs to use a large amount of steel, the cost is higher, and the process such as welding needs to be used in the construction process, and the welding and other processes are easy to appear welding deformation and other problems, while the prefabricated building structure can shorten the construction time, but in the construction process, a large number of templates and supporting structures need to be used, which increases the construction cost and difficulty. Therefore, in comprehensive comparison, the cast-free concrete floor deck has a wider application prospect and greater advantages.
