Management and control points of floor heating installation project
1.Floor heating installation fully consider the living surface elevation before installing , strictly control the elevation during installation, and set a +500mm elevation control line on the ground to avoid affecting the elevation of door opening and closing later.
2. The installation of heating pipes should prevent pipe twisting; when the pipe is bent, the top of the arc should be fixed with the limit of pipe jam , and there should be no "dead folds". a. The bending radius of of plastic and aluminum-plastic composite pipe should not be less than 6 times the pipe diameter; b. The bending radius of copper pipe should not be less than 5 times the outer diameter of the pipe.
3. When the side length of the radiant heating floor exceeds 6 meters or the area exceeds 30 square meters, expansion joint should be set. Highly foamed polyethylene foam strips with vertical and horizontal 20 mm x 60 mm are set every 3 meters or so, and the height of the foam strips is 20 mm higher than the ground. Make polystyrene partitions at the mutation sections between the walkway and the living room, at the entrance, etc. to separate the grounds of the two adjacent areas.
4. After the geothermal heating pipe is installed and cleaned, a water pressure test is carried out. a. The test pressure before concrete pouring is 1.5 times the working pressure and not less than 0.6mPa. The pressure is stabilized for 1 hour, the pressure drop is not greater than 0.05mPa. Check that there is no leakage before the next process can be carried out. b. The floor heating pipes must be poured with a pressure not less than 0.6mPa. The pressure can be removed after the concrete is filled for 24 hours. c. Floor heating pipes should be kept under pressure not less than 0.4mPa..
5. The distribution pipe assembly positioning comprehensively takes into account the cabinet layout and try to ensure that they are in one cabinet.
has given a detailed explanation of the relevant construction requirements of floor heating installation projects from the following aspects, and shared with you for reference and implementation in the project:
1. Floor heating construction scope and work content
2. Preparation before floor heating construction
3. On-site management requirements
4. Installation process
5. Water collector and water divider and related quality requirements
6. Finished product protection
7. According to the characteristics of this project, the floor heating installation project will be introduced.
