Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an underfloor heating construction method in a building.

(Prior Art) Underfloor heating has been rapidly adopted in new buildings in recent years, as it is a heating method that meets the basic physiological needs of people with cold heads and warm feet as society ages. It is especially applied to places where an unspecified number of people come and go, such as hospitals, schools, and government facilities.

The history of underfloor heating dates back to the Goryeo Dynasty (380-500 AD) in Korea.
It is said to have originated from ondol, which was made in the

In principle, Ondol uses a flue that uses waste heat from the kitchen, whereas underfloor heating circulates 40°C hot water heated by a boiler through hot water pipes installed under the floor. It is.

In addition to the above, underfloor heating is also used on the floors of some of the vast atriums of skyscrapers. The reason is that an atrium over 150m is too inefficient to heat the entire space, so it would be more efficient to heat the floor.

(Problems to be Solved by the Invention) However, since hot air is trapped on the floor of the ondol, the furniture must be equipped with legs and raised above the floor.

Furthermore, in modern buildings, hot water often leaks from hot water piping for underfloor heating, and the heat of the 40°C hot water often causes deformation or peeling of floor joists and surface materials.

Furthermore, when using the floor of a large atrium in a skyscraper, the heat dissipation to the floor is poor because the stone itself has a thickness of 20 values. Furthermore, during maintenance or when pipes become loose, the concrete, stone, wood, etc. on the floor must be destroyed.

The present invention has been proposed in view of the problems of the prior art, and its purpose is to provide an underfloor heating construction method that has good thermal efficiency, excellent workability, and easy maintenance such as pipe replacement. be.

(Means for Solving Problem L1!) In order to achieve the above-mentioned object, the underfloor heating construction method according to the present invention uses a heat insulating inorganic molded material on the back side of thin-walled stone at intervals so that hot water pipes can be accommodated. This method is characterized in that the floor finishing material formed by holding and layering is laid after hot water piping is constructed on the building frame floor.

According to the present invention, a heat-insulating material is interposed between the frame floor and the floor finishing material, if necessary.

(Function) According to the present invention, as described above, on the back side of the thin stone,
A floor finishing material is prepared in advance by layering inorganic molded materials with heat insulating properties at intervals that allow hot water piping to be accommodated, hot water piping is laid on the building frame floor, and then the floor finishing material is layered with the inorganic molded material. The hot water pipes are laid on the building frame floor so that they fit into the spaces between the shapes, and because the stone of the floor finishing material is thin, the heat efficiency of the hot water pipes to the floor is improved.

Furthermore, during maintenance or when hot water piping is replaced, the floor covering material can be attached and removed without destroying the flooring material, thereby achieving the intended purpose.

(Example) The present invention will be described below with reference to the illustrated embodiments.

(A) is a floor finishing material, in which a heat insulating inorganic molding material (2) is placed on the back side of a thin natural stone material (1) with a thickness of 3 to 15, with gaps (3) that allow hot water piping to be accommodated. They are layered together and bonded together with an adhesive (4).

Note that as the natural stone material (1), water-polished or real-polished marble is used. Marbles often used include cervejante, kansuishi, jibetsuk, trapachine, and berlino. Granite is easy to process, such as Angora Ring, Shojiri, and Kitamoto.

In place of the natural stone material (1) in the floor finishing material (^), a composite material made of highly precisely sliced marble and a ceramic material is used, which is lightweight, highly noncombustible, and easy to construct. Marble may be used, and Marp Serum (trade name: 2 Imported Crystals) is used as the composite marble.

In addition, the floor finishing material (A
) Calcium silicate hydrate (mineral name: zonolite), which has excellent fire resistance and heat insulation properties, is used as the inorganic molded plate (2) that makes up the inorganic molded plate (2).
Woody Serum (trade name: manufactured by Ube Industries, Ltd.), which is made of a ceramic material with excellent workability and adjustability, is used as the main ingredient.

Further, as the heat-insulating inorganic molding material, it is also possible to use materials made by foaming or pressurizing gypsum hemihydrate, dolomite plaster, cement, or the like.

The concrete slab (B) constituting the building frame floor
If necessary, a heat insulating material (5) such as urethane, styrofoam, zonolite, foamed rubber sheet, etc. is layered and glued on top of the slab (B) to suppress heat radiation to the same slab (B). A hot water pipe (6) made of steel pipe, rubber, or a soft synthetic resin such as PvC or vinyl is installed, and then a floor finishing material (A) is installed on the heat insulating material (5).
The hot water piping (6) is connected to the gap (3) between the inorganic molded plates (2).
Complete the entire process by placing it in place so that it fits in.

Note that when a soft vinyl pipe is used as the hot water pipe (6), it is preferable to use a long pipe and avoid connecting it in the middle.

In addition, in order to uniformly distribute the heat generated from the hot water piping (6) to the floor surface, a heat conductive material such as a sheet or mesh made of aluminum, copper, or brass is placed between the hot water piping (6) and the natural stone (1). If installed, heating efficiency will be increased. Conventionally, veneer etc. were used, but they deformed due to heat and had problems with heat resistance, but when stone is used for the floor finishing material as in the example above, such deformation is almost never seen. do not have.

Note that the floor finishing material (8) can also be fixed to the concrete slab (B) with an adhesive. In this case, after applying leveling mortar, adhere with adhesive or use the G method. others,
By joining only the joints with an organic sealant, the panels can be attached and detached during maintenance without destroying them.

As the adhesive used at this time, acrylic, rubber, urethane, and vinyl acetate adhesives for tiles are easily used. Also, if you use Gshibond as an inorganic adhesive or Tigerbond S (trade name) as a high-strength type GL bond, there will be less distortion after installation. If it is cement based, is it acrylic or SBI? emulsion of 5-8%
When added, the variation in strength is reduced.

(Effects of the Invention) According to the present invention, as described above, a floor finishing material is prepared in advance, in which a heat-insulating inorganic molded material is layered on the back side of a thin-walled stone with a space maintained so as to accommodate hot water pipes. Since the same floor finishing material is laid after hot water piping is placed on the frame floor, the floor finishing material can be easily attached and removed, and maintenance such as replacing the piping is easy. Because it is adhesive, there are no cracks in the base material or warping of the flooring material (
Become.

Furthermore, since thin stone is used as the floor finishing material, the efficiency of heat transfer to the floor is significantly improved, and an excellent heating effect is exhibited.

According to the second aspect of the invention, by interposing a heat insulating material between the floor finishing material and the frame floor, heat radiation to the frame floor is suppressed, and the heat efficiency to the floor is further improved.
