Laying barbed wire on the floor heating pipe can play the role of reinforcing ribs, strengthen the strength of backfilling and prevent cracking. In fact, the same effect can be achieved by adding anti-cracking agent into cement backfill.

Cement is alkaline, porous, absorbent and breathable, and barbed wire will corrode for a long time, so concrete reinforcement will generally crack from the joints, which will cause unnecessary trouble if it meets the floor heating pipe softened by heat. Therefore, it is not recommended to add barbed wire to the floor heating. There are many ways to achieve the same effect as barbed wire.

Extended data

1. Fixed pipeline: laying steel wire mesh on the surface of insulation layer and fixing the pipeline with nylon belt, which has fast construction speed, accurate positioning and good overall effect of pipeline installation.

2. Strong local bearing capacity of the ground: In rooms with heavy ground load such as processing workshops and garages, the use of steel wire mesh for floor heating can improve the overall strength of the ground structure layer and avoid ground cracking and collapse.

3. Accelerate heat dissipation: Because of the strong thermal conductivity of iron, the ground heat dissipation is very uniform.

4. Prevent the ground from cracking: It is best to put the barbed wire in the middle of the concrete above the pipeline (the reason why the ground tiles crack is that the barbed wire is not used, and the concrete poured on the ground is too thin, and the concrete pouring should exceed 4-5cm).
