First, the warm floor backfilling precautions


First look at whether you are a composite floor if the thickness of the concrete should reach 3 cm (3 cm) or the heat will not be uniform after the cement because the cement is also a conductor, it is indifferent to the floor tiles, as long as it can be covered.


Second, be careful not to over-press when leveling, although it will not cause bad damage to the tube, and the tube will not be heated unevenly. It is best to use a fine plank to spread on the ground for easy walking. Be careful not to scratch the tool during operation.


The third is to find the level, not leveling for the trouble of the subsequent floor. Also fill in the compact, the ground will be less in the environment after the temperature.

Second, the floor heating backfill requirements: the floor area of ​​each floor should not be too large when the floor heating is backfilled, avoiding the temperature cracks and shrinkage joints of the concrete, and also the elevation control of the concrete; the vibration of the concrete requires manual vibration, while the concrete is poured, The plasterer uses a scraper bar to flatten the surface by the elevation (ie, the upper mouth of the elevation bar), and then press it with a wooden trowel. When the concrete is applied, it is forbidden to use the iron shovel to contact the pipe.


Prevent the trolley from rolling the pipe. When casting, you must put a pedal (put the brick on the board without the coil) and make sure there are no nails on the board to protect the pipe.


Geothermal backfill concrete material requirements: the material of the floor heating layer should be C20 bean stone concrete, and the cement should be made of ordinary Portland cement with the number not less than 32.5 because of its high early strength and shrinkage during coagulation hardening. Smaller, it is more advantageous for controlling and preventing dry shrinkage of concrete; sand should be medium sand or coarse sand, the mud content is not more than 5%, and its quality should conform to the current industry standard "General Concrete Sand Quality Standards and Test Methods" Provisions. The particle size of the bean stone should be 5-15 mm, and the thickness of the filling layer of the heating tube should not be less than 30 mm. When the ground load is greater than 20KN/m2, reinforcement measures should be taken.
