The following introduction to the use of reinforced concrete floor chamber joints is quite good, and by reading the following article, you will be able to have a deeper understanding of this.
Reinforced concrete floor sub-silo joint is a device specially designed for concrete flooring to solve the stress problems caused by drying, shrinkage and temperature changes of concrete floor. There are two main categories: main seam and secondary seam.
1. Main joint: The main joint is usually a straight line joint cut immediately after the concrete is poured, and it is cut along the predetermined elevation or intersection of the ground. The main features are:
Stress release: The stress generated by the concrete floor during the drying and shrinkage process will cause the ground to crack, and these stresses can be released through the setting of the main joint, effectively preventing the ground from cracking.
Control the position of cracks: By controlling the position and spacing of the main joints, the ground cracks can be controlled in the main joints to keep the overall smoothness and beauty of the ground.
Save maintenance costs: In the case that the ground cracks are difficult to repair and treat, the main seam can become the location of the crack repair, avoiding the increase in maintenance costs.
2.Secondary joints: Secondary joints are filled with sealing material in the cracks created after the concrete floor has shrunk. Its main functions are:
Prevent debris intrusion: Secondary joints are usually filled with flexible sealing materials, which can effectively prevent debris, sewage and chemicals from entering the cracks, keeping the floor clean and safe.
Improve the durability of the ground: By filling the sealing material, the secondary seam can reduce the impact of cracks in the ground, improving the durability and service life of the ground.
Maintain the levelness of the ground: The filling material of the secondary joint has good flexibility, which can keep the ground relatively flat and avoid high and low fluctuations.
You can also expand on the following:
Design standards for silo joints: The design standards for silo joints will be different for concrete floors in different regions and different uses. For example, public buildings often have stricter design standards to guarantee the stability and durability of the ground.
Material selection of the sub-bin joint: The filling materials of the sub-bin joint usually include rubber, polymer, etc., which have good flexibility and sealing performance, and can adapt to the deformation and expansion of the ground.
Construction method of sub-silo joint: When constructing on concrete ground, it is necessary to pay attention to the cutting and filling of sub-silo joints at the appropriate time and suitable position to ensure its effect and service life.
Reinforced concrete floor sub-silo joint is an important design device, which can effectively solve the stress problems of concrete floor when drying, shrinkage and temperature change, and improve the stability, durability and service life of the ground. In the design and construction process, it is necessary to set up and deal with it reasonably according to the specific situation to achieve the best results.
