If you are in the industry, you are generally clear about the model of the sub-lattice seam expansion joint, but for ordinary people, there is less understanding of it, and the relevant content is introduced below.
Grid joints refer to the gaps between the fixed parts of the building and the wall or floor pavement of the building at certain intervals. Grid joints can be divided into two types: expansion joints and compartment joints.
1. Expansion joint: Expansion joint refers to the gap that can be deformed with the change of temperature, humidity, and other factors in the building. The type of expansion joint is usually expressed by the seismic damage coefficient (seismic damage coefficient = expansion joint width and lattice spacing). In general, expansion joints have the following characteristics:
It can absorb the thermal expansion and contraction of the building caused by temperature changes, and avoid problems such as cracking and falling off of the wall or ground
Mitigate the impact on the building and improve the seismic performance of the structure;
Avoid shrinkage or expansion problems caused by changes in humidity.
2.Warehouse joint: Warehouse joints refer to the gaps between buildings such as large warehouses or factories that divide buildings into several warehouses or partitions, and between them. The main function of the sub-silo joint is to divide the structure of the building and prevent damage caused by the overall settlement or vibration of the building. The type of sub-silo joint depends on the size of the building and the number of sub-silos. The characteristics and applications of the sub-bin seam are:
It can reduce the weight of the overall structure of the building, reduce the possibility of settlement and deformation;
It is convenient for the separate use and management of each sub-warehouse or partition of the building;
While preventing the damage of the building structure, it can ensure the overall stability of the building.
In the field of building construction, lattice joints are widely used in various types of buildings, such as residences, office buildings, commercial centers, gymnasiums, etc. They can effectively deal with the thermal expansion and contraction of the building in the process of use, and ensure the structural stability and service life of the building. The setting of lattice joints needs to be reasonably selected and designed according to the specific building structure and use needs to ensure its good function and effect.
