Welded wire mesh is mostly used for plastering and reinforcing internal and external walls of construction sites. According to the requirements of the region and design institute, the specifications are different. The commonly used specifications are: 1.5 cm hole and 2 cm hole, wire diameter is 0.4-0.9 mm.
Welded wire mesh is generally used for insulation of exterior and interior walls of buildings. Its purpose is to effectively prevent cracks, hollowing, skin falling off and so on. Another advantage of installing and laying wire mesh is easy plastering and good reinforcing performance.
In order to ensure the construction quality of the project, it is necessary to increase the requirements and testing of crack-proof materials. Xiangfeng Wall Insulation and Crack-proof Plant in Anping County specializes in the production of plastered wire mesh and galvanized wire mesh. The quality is reliable and the price is excellent.
Welded wire mesh in building floor heating
1. Fixed pipe: laying steel wire mesh on the surface of insulation layer with nylon tie to bring fixed pipe, which is characterized by faster construction speed, accurate positioning and good overall effect of pipe installation.
2. Enhance the local load-bearing capacity of the ground: In rooms with large ground loads such as processing workshops and garages, the steel mesh used for floor heating can improve the overall strength of the ground structure layer and avoid ground cracking and collapse.
3. Accelerate the heat dissipation speed: Because iron has strong thermal conductivity, the ground heat dissipation is very uniform.
4. Prevent ground cracking: The steel wire mesh must be placed in the middle of concrete above the pipe material (the reason for the cracking of the ground cracking tile is not to use the steel wire mesh, the second reason is that the ground concrete is too thin to be poured, and the concrete pouring should be more than 4-5 cm).
The wire mesh on the coil is backfilled to protect the coil. The function of the wire mesh is to heat the coil more evenly, and make the heat source become the surface heat source, so as to expand the heat dissipation area, and make the distribution of the heat dissipation surface more uniform and increase the thermal stability. At present, it is better to add than not, but there is no final conclusion on whether to put it on the pipe or under the pipe, and there is no harmful effect. The size of the grid may depend on the size of the pipe, and the coil spacing is also different. Wire mesh is used for crack resistance, because the ground is easy to crack because of the severe heat rise and cold shrinkage, so it is necessary to add wire mesh crack resistance. The project generally uses 200*200, 4 mm diameter cold drawing wire.
Whether to lay steel wire mesh in geothermal installation, the answer I give is: it is necessary!
