Pipe-embedding type underfloor heating construction method capable of preventing ground cracks

Abstract

The invention discloses a pipe-embedding type underfloor heating construction method capable of preventing ground cracks. The method comprises the following steps that firstly, construction preparation is conducted, specifically, a water heating pipeline arrangement diaphragm is drawn according to process requirements, a plan of the set position and number of expansion joints is made, and materials are prepared according to the arrangement diaphragm and the planned number of the expansion joints; secondly, surface clearing and leveling are conducted on a structural layer; thirdly, a heat insulating layer and a reflecting layer are laid on the structural layer sequentially; fourthly, a water heating pipeline is laid, then foamed polyethylene foam strips are mounted so as to form the underfloor heating expansion joints, and finally fixing clamps are adopted for fixing the water heating pipeline; fifthly, tap water is led into the water heating pipeline, and a water heating system is subjected to primary bulge test; a packing layer is poured on the reflecting layer; ground maintenance is conducted on the poured packing layer, and the water heating pipelines is subjected to secondary bulge test; and a water collector and a water knockout trap are mounted. The obtained pipe-embedding type underfloor heating construction method capable of preventing the ground cracks has the effects that the construction steps are simple, and the ground cracks can be effectively prevented.

Description

technical field [0001] The invention relates to a floor heating installation and construction process, in particular to a pipe-buried floor heating construction method capable of preventing ground cracks. Background technique [0002] With the improvement of people's living standards, in order to resist the severe cold in winter, many families will install floor heating during decoration. According to different heating media, floor heating is mainly divided into electric heating and water heating. Compared with electric heating, water heating has the advantages of low cost, long service life, and good thermal stability, so it is more popular. [0003] At present, the traditional plumbing pipe laying methods mainly include back-type piping method, S-type piping method and mixed-type piping method. Among them, the back-type pipe layout method meets the special temperature requirements of local areas by adjusting the pipe spacing. However, if the layout area is too large, ther...

Problems solved by technology

Among them, the back-type pipe layout method meets the special temperature requirements of local areas by adjusting the pipe spacing. However, if the layout area is too large, there will be no expansion joints in the middle, which will cause uneven thermal expansion and contraction of the filling layer and the surface layer concrete. Arc-shaped cracks; when the S-shaped piping is arranged in a large area, the temperature will be high at one end and low at the other end, so it is generally used in a narrow space; the hybrid piping method is mainly used in large-area indoors, but this type of piping Irregular cracks will appear under the influence of thermal expansion and contraction

After the above three methods are applied to large-scale plumbing, there will be different degrees of ground cracks, which will affect the appearance and the distribution of heating
