Because the heating of the ground is achieved by means of plastic pipes concealed under the floor, it is difficult to cope with the unsatisfactory heating results or the need for maintenance after the completion of the laying work. Floor heating is to bury the hot water pipe in the cement layer of the ground, the laying length and gap of the water pipe, whether the design of the heating system is reasonable, the laying position of the floor heating pipe, the thickness of the pipe diameter, the size of the water pipe gap, etc. will affect the heating in the later period. Even if there is no problem with the design of the floor heating, if the construction process is not completely operated according to the design drawings, the heating will not be heated.
In addition, since the degree of bending of the pipe cannot be correctly grasped during pipeline construction, the water flow in the pipeline will be affected and the expected heating effect cannot be achieved; if too much gas is stored in the pipeline, the pipeline will be cut off and the system will lose balance. Heating failed. In addition, because the floor heating also needs to cover the pipeline during the installation process, ashes and home improvement, it will appear like pipe damage, can not find the pipeline and so on.
As far as households are concerned about the service life of pipes, in practice, the lower the temperature of the heat source, the longer the life of the pipe, and vice versa, it will shorten the life of the floor heating. The 50-year service life promised by the floor heating companies is a very vague concept and cannot truly represent the life of the floor heating. The installation company will not take the initiative to take responsibility for this responsibility. After a few years, these problems will be exposed. It is also a major drawback in the development of underfloor heating.
If you want to enjoy floor heating without worrying about yourself, choosing a professional and regular floor heating company is a prerequisite.
First, the preparation before laying
Ground level measurement: Measure the flatness of the ground and agree with the owner whether ground leveling should be done.
Laying the floor is not required to be horizontal and smooth. The flatness of the ground is not much different from that of 5 mm, and no ground leveling is required.
The installation height of the floor differs from the height of Other ground materials by more than 5 mm, and an easy method can be used for leveling the floor.
The flatness error is large or the height difference from other ground materials is large. Cement mortar is recommended for full leveling.
After ground leveling, the local flatness error must not exceed 3 mm.
Ground-level humidity measurement: Use the electromagnetic wave type moisture content measuring instrument to measure the humidity of the ground, one test point every 1.5 to 2 meters; and the local key measurement of the construction of the mixed mortar in the early stage. The humidity on the ground is large. It is recommended to delay the installation period, add moisture-proof mats or make the floor waterproof.
Determine the installation method and calculate the amount of auxiliary materials: Provide specific installation methods for the installation orientation of the floor, skirting board, sliding doors, floor-to-ceiling windows, low cabinets, floors, stairs, etc., for the owner to choose and determine. If the owner’s special requirements and technical requirements are inconsistent, special instructions signed by the owner are required.
Measure the actual area, sketch the size of each part, and calculate the actual floor and accessories.
Establish a contract with the owner to determine the model and model of the purchased product.
Second, the floor to the scene of the open inspection
The moisture content of the floor - the solid wood floor moisture content is close to the local equilibrium moisture content.
The appearance quality of the floor - film quality and wear resistance, cracks, processing ripples, etc.;
The main dimensions and deviations of the floor - length, width, thickness, etc.;
Floor shape position deviation - assembled from the seam, assembly height difference and warpage.

Third, the choice of floor color
Solid wood flooring is a natural material and chromatic aberration is normal. Through manual selection and adjustment, the transition can be natural, beautiful, lively and full of vitality.
For wood species with relatively small color difference, do not grade and adjust directly when laying.
For the color difference of the species, can be divided into deep and shallow categories. Different shades can be installed in different areas or in different shades;
In the installation of floors of the same kind of color, in principle, the chopping board and the chopping board are also laid.
Fourth, the laying of keel requirements
In accordance with the length of the floor, determine the spacing of the keel; generally half of the length of the floor is set to the spacing of the keel; the spacing of the keel should not be too large.
According to the length of the laying floor, a reference line of 300 mm from the wall is used to ensure that the mounting position of the keel is at right angles to the reference line.
Determine 2-3 keels as the benchmark, and adjust the height between the ground material and other ground materials to make the transition natural and beautiful. Strictly control the flatness of the upper surface of the keel.
Use a wooden wedge or other hard material to lift the suspended keel; use a dragon king rubber tyrant or styrofoam to secure the wooden wedge and keel, and fill the suspended part of the keel.
Fifth, floor laying requirements
A wooden wedge is used between the floor and the wall to ensure that the floor is 8-12 mm from the wall.
After laying the first two rows of flooring, it is necessary to straighten the wire; during the laying process, pull the wire straight to ensure the laying quality.
To divide by room or area, add transitions (expansion joints) to prevent the floor from arching.
Consciously adjust the color of the floor to make it natural.
The skirting board is tightly fitted and securely mounted.
