4 The water collector and distributor of this project are set at the lower part of the washbasin.
II.
Public area on the first commercial floor and tower A The floor heating laying project on the 7th to 34th floors of Block B, and the floor heating construction on the 2nd to 6th floors of the commercial part is not considered temporarily.
All components and parts inconsistent with the samples shall be removed from the site.
Site management requirements 4.
There must be a special warehouse for coil storage on the site.
It is strictly prohibited to expose to the sun; The mechanical input shall meet the labor requirements, such as: electric box, hot-melt machine, scissors, pressure gauge, pressure test tool materials, etc.
The floor heating should enter the site and actively cooperate with the preparation of a special floor heating construction plan based on the actual situation of the site.

Image progress of floor heating installation project – construction scope and work content of floor heating of the project 1.
Strictly control the elevation of the floor.
3 The handover between installation types of work must be accompanied by the handover form of the team.
4 Water blowing shall be carried out for pipeline construction in winter to prevent frost damage.
Large quantities of components and parts entering the site shall be compared with the samples of components and parts sealed.
Finished product protection 7.
Meanwhile, the installation and maintenance of the valve shall be considered.
3 Ensure sufficient construction technical force, recheck design parameters of drawings, make reasonable suggestions and make secondary detailed design of drawings.
Installation process 5.
The bridge shall be added to the cold water pipes, and it is better not to add them to the hot water pipes, because the pressure of the hot water pipes is small.
It is strictly forbidden to expose the pipeline beyond the floor surface.
Under special circumstances, it must be reported to the supervisor and the image records must be made.
4 In order to ensure the construction quality and visual effect, it is required that the floor heating construction should be “sample first” before the construction of each installation process, and the large-scale construction can be carried out after the confirmation of the on-site Party A and the supervisor.
When installing the heating pipes, the location of the water collector and distributor must be matched; The handover work before the radiant heating of tower A and B construction sites (the handover can be carried out in layers and stages).
Finished product protection 1 This project is a fine decoration project, with high requirements for finished product protection to avoid quality, safety hazards and damage to finished and semi-finished products caused by cross construction.
The installation position is in accordance with the requirements of the drawing.
This paper explains the construction requirements of the floor heating installation project in detail from the following aspects:, Share for reference in the project: 1.
Process requirements for floor heating installation 2.
2 Be familiar with the floor heating construction drawings carefully, and the on-site technicians shall check in advance whether the control of the on-site pipeline route and the ground control elevation can meet the requirements of pouring, and can find problems.
Preparation before floor heating construction 3.
All components and parts must be submitted for confirmation before sealing.
VI.
The coordinates of the water supply and return of the water collector and distributor are close to the internal corner.
The horizontal coordinate of the water supply pipe of the water collector is 8cm from the decorative surface of the internal corner; The center distance of water supply and return is 8cm, and the longitudinal coordinate is consistent with the center of water collector and distributor.
3 Material requirements When entering the site, the materials shall be accepted in strict accordance with the specification requirements, and the materials entering the site shall be stacked by category.
III.
Site management requirements 1.
Preparations before floor heating construction 1 As the floor heating construction team has not surveyed the site for a long time, in order to meet the needs of the installation project, all disciplines should cooperate with each other.
The plan should be practical and reported to Party A and the supervisor for review; Before pipe laying, take the initiative to optimize the pipe laying in combination with other professional installation teams on site, and the sample households shall take the lead.
3 The floor heating water collector and distributor plays a very important role in the floor heating construction, and is the heart and blood of the floor heating system; The water separator is installed at the top and the water collector is installed at the bottom, with a center distance of 200, and the center of the water collector is not less than 300 from the ground.
VII.
3 For the laying of radiant heat, if the pipeline is damaged during the construction, it is strictly prohibited to use the hot melting method.
Construction scope and work content of floor heating 2.
5 The installation support of water collector and distributor shall be firmly buried, horizontal and inclined to the vent valve.
IV.
2 During the laying of floor heating, it is strictly prohibited to have construction hidden dangers such as dead angle bending, bending and flattening.
Air compressor shall be used to blow the residual water in the pipeline clean.
If one frost damage is found, 5000 yuan will be fined.
Overview of key points of floor heating installation project in combination with the characteristics of the project 8.
The cold and hot water pipes shall be handed over to the floor heating team under pressure after construction.
2 Meeting system: The person in charge of floor heating construction shall attend the regular supervision meeting at 14:30 p.m.
If the ground is super high, it shall be solved through communication with civil engineering technicians in advance.
Key overview combining the characteristics of the project 1.
In case of pouring without reporting, a heavy penalty of 5000 yuan will be imposed for each place.
Personnel arrangement and mechanical delivery: Tower A and Tower B are two super high-rise buildings.
6 The cold and hot water buried pipes shall avoid the ground heating pipes, and the cold water pipes shall avoid the hot water pipes.
Installation process flow Five water collector and distributor installation and relevant quality requirements 1.
It is necessary to protect not only the finished products within the scope of this type of work, but also the finished products of other types of work units.
For each place found, 1000 yuan will be fined, and it must be repaired and improved.
Overview of floor heating installation process ▲ Hall expansion joint setting ▲ Long corridor expansion joint setting (mainly for the floor heating in the public area of the first commercial floor) ▲ Floor leveling, recheck whether the floor heating pipe is super high, and after the concrete pouring, no exposed pipe is allowed.
every week, report the completion of this week, the plan for the next week and the matters to be coordinated and solved by the general contractor; If there are technical difficulties in cooperation, the construction personnel shall report to the supervisor and immediately hold a meeting to solve them.
It is required to have a general technical director for floor heating and two operation team leaders.
The progress requires the completion of the annual image node requirements, the installation works and the main decoration are carried out simultaneously, and the problems existing in the handover of the working surface should be timely coordinated with the supervisor and Party A, without deliberate delay.
2.
▲ Auxiliary measures shall be taken to prevent “dead break”..
Due to the large number of houses, each house type has a special person for construction.
Installation of water collector and distributor and related quality requirements 6.
The construction personnel should be fixed.
