Floor heating mesh is also called steel mesh. Its functions in underfloor heating projects are:
1. It is convenient for pipe installation and the construction speed is faster. fixed above the steel mesh.
2. Avoid the occurrence of undesirable phenomena such as cracks, cracks and floor collapses.
3. The thermal conductivity of the steel mesh is very good, which can promote uniform heat dissipation.
What is the anti-cracking belt for underfloor heating?
When overlapping the anti-cracking net, the overlap on both sides should not be less than 200~300mm.
The functions of the anti-crack mesh for underfloor heating:
1. It may have a fixing effect on installed pipes. Lay the underfloor heating mesh on the surface of the insulation. Diaper and tie it upwith nylon with a fixed hose. It can make the construction speed faster, construction positioning accurate, and the overall effect of pipeline installation better.
2. It is useful to improve the local bearing capacity of the floor in places with large floor loads, such as processing workshops and garages, underfloor heating mesh used for underfloor heating can increase the resistance overall soil. the soil structure and avoid soil rupture and collapse?.
3. The underfloor heating mesh is also very effective in dissipating heat. Since steel bars have relatively strong thermal conductivity, the ground dissipates heat very evenly and quickly.
4. To prevent floor cracks, a floor heating mesh should be laid between the pipes and the concrete. The reason for the floor cracking was that the floor heating mesh did notwas not used and the concrete on the ground was too thin.
What should you pay attention to before installing and laying an underfloor heating network?
1. When the steel bars are thick and the welded mesh cannot be bent, 1-2 less steel bars can be welded to the ends of the welded mesh, then the two ends are inserted into the beam and tied with straight bars. Use on-site bonding methods to compensate for reduced transverse steel bars, additional steel bars and welded mesh connections at each node should be used.
2. Before installing the underfloor heating mesh, an installation plan for the underfloor heating mesh must be drawn up. When installing underfloor heating mesh, installation guidelines should be based on on-site and on-site practice. the efficiency of the personnel responsible for the equipment.
3. For the trelliswelded lily which needs to be anchored at both ends in the beam, when the longitudinal steel bars of the floor heating mesh are thin, use the bending deformation function of the floor heating mesh to bend first. the middle part of the welded mesh upwards. Make sure both ends can be inserted into the beam one after the other, then lay the floor heating mesh flat.
4. Between the ends of the welded mesh, the overlap length of the steel bar cover joint shall not be less than 1.3 times the anchor length la and shall not be less than 200 mm in the area of overlap. , each welded mesh for floor heating There shall be no less than one transverse steel bar on each sheet of floor heating mesh, and the distance between one transverse steel bar outside the two underfloor heating mesh sheets must not beas be less than 50 mm.
5. When one of the two underfloor heating mesh sheets in the overlapping area has no transverse steel bars, the overlapping length of the ribbed underfloor heating mesh sheet shall be 1.3 times the anchor length la and must not be less than 300 ㎜. When the diameter d of the longitudinally stressed steel bars in the overlap area is ≥ 10 mm, the overlap length should be increased by 5 days.
After laying the underfloor heating pipes, it is often only the first layer that requires anti-crack strips. Its function is to stretch the layer of cement that will cover the underfloor heating pipe to prevent cracking, so putting more layers is of no use.
Floor heating mesh, also known as underfloor heating mesh and special floor heating mesh, is made of steel wireHigh quality low carbon Q235 welded together. It has the characteristics of flat mesh surface and firm welding. uniform mesh joints and holes. Its function is to improve the overall strength of the insulation board and facilitate the installation and fixing of the heating pipe. The specifications of commonly used underfloor heating mesh are: wire diameter 2mm, mesh 10cm × 10cm, length and width 1m × 2m.
