Recently, I found that more and more people have begun to pay attention to knowledge sharing: foam concrete sub-silo seam model, the following is a description of the relevant content, if you are more interested in this, you can come to understand.
Foamed concrete is a lightweight building material made from a mixture of cement, sand, water and foaming agent. It is characterized by low density, good heat preservation, low water absorption, convenient construction, etc., and is widely used in buildings, roads, bridges and other projects.
The sub-silo joints of foam concrete in the building are to prevent cracks in the structure under the action of external forces such as temperature changes or **, so as to ensure the safety and stability of the building. The sub-silo seam is generally divided into the surface layer sub-silo seam and the base layer sub-silo seam.
The surface layer is generally located at the surface layer of the outer wall, roof, ground and other surface layers of the building, which is used to separate materials at different temperatures and avoid cracking caused by thermal expansion and contraction. The common types of surface layer sequential joints are A-type, C-type, U-type, L-type, etc. Among them, type A is used for the internal silo joint of the surface layer, type C is used for the silo joint at the corner of the wall, window sill, etc., U-type is used for the sub-silo joint of the outer wall and roof edge, etc., and L-type is used for the sub-silo joint at the junction of the wall and the ground.
The sub-silo joint of the base layer is generally located at the base of the building structure, which is used to divide the structure of different parts and prevent the crack from propagating. The common types of base sewing are Y-type, T-type, YU type, etc. Among them, the Y type is used for the silo joint at the junction of beams and columns, the T type is used for the silo joint at the junction of the slab beam and the floor slab, and the YU type is used for the silo joint at the junction of the stair tread and the floor slab.
Extended description: 1. The width and depth of the sub-silo joint need to be designed according to the specific engineering situation, and factors such as structural deformation, material expansion coefficient and temperature change should generally be considered.
2.The construction method of foam concrete silo joint comprises prefabricated silo joint and cutting seam construction. Prefabricated silo joints are reserved before construction, and then concrete is poured during construction. Seam cutting construction is to use mechanical tools to cut out the silo seam after construction.
3.The foamed concrete bin joint can improve the sealing performance by filling the sealing material, and prevent water, steam and other media from entering the bin seam and causing damage.
4.In the design and construction process of foam concrete silo joints, it is necessary to consider the load-bearing performance, seismic performance and fire performance of the building to ensure the overall safety of the building.
5.The selection of foam concrete sub-chamber joints also needs to consider factors such as the durability, reliability and economy of the material to meet the requirements of the project.
