Overlap length of anti-crack mesh for underfloor heating

Introduction The overlap length of the anti-crack net for floor heating. At the overlap point of the anti-crack net, the overlap on both sides should not be less than 200~300mm. The functions of the floor heating anti-crack net: 1. It can fix the installed pipes.

Overlap length of anti-crack mesh 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. Layer and tie it with nylon with a fixed pipe. 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 trellis is also verys 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 was not used and the concrete on the floor 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 field bonding methods to compensate for reduced transverse steel bars, additional steel bars and welded mesh connections ateach node must 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 welded mesh that 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 lap joint should not be less than 1.3 times the lengthr anchor la and shall not be less than 200mm in the overlapping area. , 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 should not 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.

What are the application advantages of hot-dip galvanized floor heating mesh?

Once the underfloor heating pipes have been laid, anti-crack strips are often placed in a single layer. 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 floor heating mesh and special floor heating mesh, is made of Q235 low carbon steel wire of high quality welded together. It has the characteristics of flat mesh surface and firm welding. uniform mesh joints and holes.Taste. 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.

1. The metal mesh inHot-dip galvanized underfloor heating steel is automatically butt-welded by hot-dip galvanized wire. It has the advantages of firm welding points, flat mesh surface, mechanized production and large daily output. .It is particularly suitable for underfloor heating construction.

2. The wire diameter can be thickened or thinned according to the mesh size, and the price is relatively moderate.

3. Can be mass produced as required. The color surface is black or galvanized or sprayed with white baking paint or green paint.

4. Used in professional projects for the construction of underfloor heating and building partitions or external insulation.

5. It can easily fix the pipes to prevent them from being misaligned during the ash spreading process;

6. It effectively improves the bearing capacity of the soilt pipes. are not easily crushed;

7. It can prevent floor cracks;

8. The floor heating mesh can effectively accelerate heat dissipation and increase heating efficiency.

The surface of the mesh is very smooth without additional treatment, the solder joints are firm, and all solder joints are smooth and without protrusions. The mesh after anti-rust treatment has good anti-rust and anti-corrosion effects. .
