The hot water pipe 270 is in contact with the groove 211 to be surrounded by a thin metal foil material made of aluminum or copper to promote heat conduction.

In constructing the prefabricated ondol floor panel heating system according to the present invention, a plurality of panel height adjustment fixtures 300 are vertically and horizontally arranged on the slab base layer 100 as in the case of construction of a double floor material such as a normal access floor. In addition, a heat insulating sound absorbing panel such as a foamed pearlite or vermiculite panel, which is a heat insulating sound absorbing material 400, is installed.

Subsequently, the ondol panel 200 is assembled on the panel height adjustment fixture 300 to form an air layer 500 between the ondol panel 200 and the lower insulation sound absorbing panel to effect insulation, sound absorption, shock, and vibration absorption.

In the quantitative composition of the high-strength fast-hard ondol panel, when the composition ratio of the high-strength fast-hard cement is less than 57% by weight, the strength of the product is lowered. This has the disadvantage of being reduced. The use of wood chips increases the specific gravity of the product below 10% by weight, and the specific gravity decreases above 30% by weight, but the strength and heat resistance decrease.

And the composition of the heat transfer and spinning function coating applied on the ondol panel 200 has a chemical composition of SiO ₂ 17-22%, Al ₂ O ₃ 38-43% by weight of the chemical composition so as to have a desirable heat transfer and spinning ability 20 to 30% of a colloidal silica and aluminum phosphate were added as a binder to a paint composed of 17 to 22% of Cr ₂ O ₃ , _{2 to} 7% of Fe ₂ O ₃ , 3 to 8% of TiO ₂ , and 7 to 12% of ZrSiO ₄ .

It is a material that facilitates.

The hot water pipe 270 installed in the recess 211 of the ondol panel 200 is formed by forming a polyethylene resin having a density of about 0.95 or less in a tubular shape, and then horizontally paralleling the surface of the bottom panel with a crosslinked polyethylene tube crosslinked by electron beam irradiation. Install to achieve. The bottom of the panel attaches a galvanized steel sheet with a thickness of 0.5 to 1.0 mm to increase mechanical strength.

In the hot water pipe 270, a pipe formed of a synthetic resin material containing 20 to 50% of thermal conductive powder, for example, Al ₂ O ₃ powder, may be used to improve thermal conductivity. The hot water pipe 270 may also be used. Ordinary hot water pipes may be used.

Between the ondol panel 200 and the slab base layer 100 is laminated with a foamed pearlite or vermiculite, which is a heat insulating sound absorbing material 400 on the lower floor with a certain air layer 500. The adiabatic sound absorbing material is formed into a plate having a predetermined thickness by adding sodium silicate, methyl cellulose or colloidal silica as a binder to expanded pearlite or vermiculite particles having a size of 2 to 5 mm. In some cases, the granular material may be sprayed and laminated on the floor as it is without forming into a sheet material.

As described above, the ondol panel according to the present invention is formed by attaching an additional plate to a panel body such as a floor plate such as an access floor to form a recess, and pipe the hot water pipe to the recess to supply and circulate hot water.
