Through the exchanges with many netizens in the past few days, many friends have asked about the topic of the construction process of the sub-warehouse joint of the earth, and this article will introduce the places that everyone is more concerned about.
Separate joints refer to the division of a certain separation area on the floor according to the design requirements in the construction process of the concrete floor, forming a series of parallel gaps. These gaps are called sub-silo joints, and their main function is to prevent the floor from being affected by thermal expansion, cold contraction and stress deformation, and improve the stability and durability of the floor.
The construction process of the earth floor sub-warehouse joint mainly includes the following steps:
1. Planning and design: Before the construction of the floor, determine the position, width and length of the silo joint and other parameters according to the design requirements and the current situation. Generally, the width of the sub-bin joint is generally 3-5 mm, and the length is determined according to the size and layout of the floor.
2.Construction preparation: clean the construction area and ensure that the floor surface is clean and flat. Then, mark the position of the bin seam, which can be calibrated using a rope or marking tool. At the same time, prepare the tools and materials required for construction, such as counterweight piers, steel mesh sheets, etc.
3.Reinforcement installation: According to the design requirements, install the reinforcement mesh at the position of the sub-silo joint. The steel mesh sheet should be fixed firmly and evenly integrated with the pouring of floor concrete.
4.Pouring concrete: Pour concrete evenly into the construction area in accordance with the specified mix ratio and pouring process requirements. During the pouring process, it is necessary to ensure that the concrete can smoothly cover the entire sub-silo joint and fill it to ensure the overall load-bearing and stability of the floor.
5.Leveling: After the concrete has just been poured, use a vibrator or trowel to level the concrete. By vibration and trowel, the air pores on the concrete surface are removed and the surface becomes smooth and smooth.
6.Expansion of the sub-silo joint: Before the concrete begins to harden, a special tool is used to extend the sub-silo joint. This ensures that the gap left by the silo joint is more obvious, and there is a certain space to accommodate the expansion and contraction deformation of the concrete.
7.Gap filling: After the floor concrete is completely dry, a special caulk can be used to fill the sub-silo joints. Caulk fills gaps and provides a good seal to keep dust and moisture out of the crevices, while also enhancing the overall strength of the floor.
The extended description of the construction process of the sub-warehouse joint of the floor can also include the following:
1. The reserved position of the silo joint: in the planning and design, it is necessary to reasonably determine the position of the silo joint according to the use needs and characteristics of the floor. Under normal circumstances, the sub-silo joints are generally set at the edge position of the floor and the cross-sectional change to minimize the thermal expansion and contraction deformation of the floor.
2.Choose the right counterweight pier: A counterweight pier is a weight used to support and fix the position of the silo joint. Before construction, it is necessary to select the appropriate counterweight pier according to the use requirements of the floor and the length of the sub-bin joint. The height and number of counterweight piers should be determined according to the floor size and load to ensure the stability and reliability of the sub-silo joints.
3.Water injection and curing of sub-silo joints: After the concrete of the floor has just been poured, the method of water injection curing can be used to protect the sub-silo joints. Water injection curing can keep the surface of the floor moist, reduce the shrinkage and deformation of concrete, and improve the compactness and strength of the floor.
The construction process of the floor is a complex and important process, through reasonable planning and design and strict construction operations, the stability and durability of the floor can be effectively improved, and its service life can be prolonged.
