The present invention relates to an ondol floor capable of constructing a unit ondol floor on which a heat dissipation pipe of aluminum material is inserted into a groove of an insulation material.

Conventionally, an ondol floor is laid with a heat insulating material over an entire floor, pipes are arranged thereon, connected to each other with nipples, and finished with a plurality of flooring materials.

As such, the conventional ondol floor brings each part to the construction site, and there is a inconvenience in that the work must be done one by one.

Moreover, what was disclosed by the publication of Unexamined-Japanese-Patent No. 20-0300312 is proposed as a conventional nipple, for example. According to this publication, as shown in FIG. 10, the pipe 3 is inserted into the nipple 1 connecting the pipe 3 in various forms, and then the clamp band 2 is compressed by a crimping pipe 3. In the nipple to tighten and prevent watertightness and separation, the O-ring groove 7 is formed in at least two places in the groove 6 between the stone jaw (5) formed by the tip of the nipple (1) O-ring (8) , 8 ') are provided so that the O-rings 8, 8' are located at the center of the clamp band 2.

On the other hand, as shown in FIG. 11, what was disclosed by the publication of Unexamined-Japanese-Patent No.1994-1423 is proposed. According to this publication, in connecting and connecting a heating tube to a hot water distributor using a socket tube and a nut, the front end of the socket tube is formed of a single tube and the front end of the nipple having a plurality of locking jaws 21 ( 22) to form a flange 23 at the rear end thereof, and an insertion portion 24 fitted to the socket tube at the upper portion thereof.

Since the inclined surface 21a of the nipple 22 is formed to be inclined upwardly (θ) from the right end toward the center, that is, the flange 23, the heating pipe is connected using the fastening parts of the nut and the socket pipe.

As described above, in order to ensure a reliable connection between the nipple and the pipe, a separate tightening part such as a clamp band or a nut is further used, so that the distance between the pipes is increased by the fastening part, and thus the construction must be performed with a long pipe. According to the waste of the material, the tightening workmanship is required because the assembly is inferior, more parts are consumed, there is a problem that the economy is inferior.

The present invention has been made in order to solve the above problems, and an object thereof is to provide an ondol floor that can be assembled in a unit unit by modular operation.

Ondol floor of the present invention for achieving the above object is a heat insulating material formed grooves; Ondol ridge flooring formed with coupling grooves and coupling protrusions on both sides; It comprises a heat dissipation member interposed between the insulation and the ondol flooring,

The heat dissipation member includes a heat dissipation pipe inserted into the recess and a heat dissipation plate integrally formed on an upper surface of the heat dissipation pipe.

According to this configuration, since the heat dissipation pipe is mounted in the groove, the modularization work is possible and the assembly work can be performed in units of sections.

In the above configuration, the lower surface of the heat dissipation pipe is further formed to be fixed to the groove is inserted, both sides of the fixing plate is preferably bent upwardly inclined toward the outside.

The apparatus may further include nipples connecting the heat dissipation pipes, wherein the nipples include first and second connection parts connected between the heat dissipation pipes; Comprising a plurality of first and second projections formed along the longitudinal direction on the outer peripheral surface of the first and second connecting portion, the inclined surface formed on the first projection and the second projection is downwardly directed toward the center at both ends of the connecting portion It is a photograph downwardly inclined surface, ○-ring is installed on the downwardly inclined surface, the inner diameter of the heat radiation pipe is preferably chamfered. By this structure, connection between pipes can be reliably performed without using fastening parts, such as a clamp band and a nut.

Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will now be described with reference to the accompanying drawings, where like reference numerals refer to like parts, and detailed description thereof will be omitted.

1 is an exploded perspective view showing an ondol floor according to a preferred embodiment of the present invention, Figure 2 is an enlarged perspective view of the heat radiation member of FIG.

As shown in Fig. 1 and 2, the ondol floor 200 of the present embodiment is largely composed of a heat insulating material 210, a heat dissipation member 230, the ondol flooring material (250).

The heat dissipation member 230 includes a heat dissipation pipe 231 and a heat dissipation plate 236 formed on an upper surface of the heat dissipation pipe 231. The heat dissipation pipe 231 functions as a piping through which hot water and cold water pass, and in the case of hot water, heat dissipation is carried out, and in the case of cold water, heat absorption is performed. Here, the case of hot water is demonstrated.

The heat dissipation pipe 231 is accommodated in the recess 211 of the heat insulator 210, and the heat dissipation plate 236 is in contact with the reinforced flooring material 250. When the width of the heat sink 236 is narrow, it is preferable in terms of heat transfer that a heat conduction plate 270 similar to the area of the reinforced flooring material 250 is interposed therebetween. Of course, when the size of the heat dissipation plate 236 can be molded like the heat conductive plate 270, the heat conductive plate 270 can be omitted. The heat dissipation member 230 is preferably extruded from an aluminum material having excellent thermal conductivity.

On the other hand, as shown in Figure 3, the lower surface of the heat dissipation pipe 231, it is preferable that the fixing plate 240 is inserted into the recess 211 is further formed.

That is, when the heat insulating material 210 is styrofoam, when the fixing plate 240 is inserted into the groove 211, it is dug into and caught, so that it does not come out well. In addition, when molding the heat insulating material 210 with mortar or soil, it is buried therein to serve as a fixed reinforcing bar.

In order to further reinforce this, it is preferable that the inclined bent portion 240a bent upwardly inclined toward both sides of the fixing plate 240 is formed. The inclined bent portion (240a) also serves as a guide to ride well into the groove (211).

On the other hand, as shown in Figures 1 and 2, it is preferable that the inner diameter of the heat dissipation pipe 230 is chamfered. The chamfering portion 231a serves as a guide surface for guiding both ends of the nipple 100 described later to the inside of the heat dissipation pipe 230.

The heat insulator 210 may be implemented as an integral hexahedron such as concrete or mortar as shown in FIG. 1, but as shown in FIG. 4, a heat insulator filled with ocher 313 which comes out of healthy far infrared rays may be used. That is, the ocher insulation is composed of a box 310 consisting of a bottom and a wall, and a recess 311 cut at both ends of the wall. After attaching the heat dissipation pipe 231 to the groove 311, the manufacturing process is completed by filling the box 310 with soil or loess.

Standardized reinforced flooring material 250 is made of HDF (High Density Fiberboard), plywood, stone material and the surface is treated with HPL (High Pressure Laminate) or LPL (Low Pressure Laminate). Coupling protrusions 251 and coupling grooves 256 are formed on both sides of the reinforced flooring material 250, and assembled to complete the ondol floor. While the coupling protrusion 251 and the coupling groove 256 are assembled in the front and rear sliding manner, as shown in FIG. 10, the reinforced floor of the coupling protrusion 251 ′ and the coupling groove 256 ′ are fitted to the left and right sides to be coupled. There is a flooring 250 '. The ondol floor 250 is adhesively fixed to the heat sink 236 or the heat conduction plate 270.

The size (width * length) of the reinforced flooring flooring material 250 is 190mm * 1200mm, 200 * 1800mm, 200mm * 2400mm for HDF or plywood, and 300mm * 900mm, 200mm * 600mm for stone .

In this way, the heat dissipation member 230 may be inserted into the recess 211 of the heat insulating material 210, so that the assembly is convenient and modular and can be partitioned.

Hereinafter, the nipple which connects the above-mentioned heat radiation pipe is demonstrated.

5 is a side view showing a nipple according to a preferred embodiment of the present invention, Figure 6 is a side cross-sectional view showing a state in which the nipple of Figure 5 is connected.

1, 5, and 6, the nipple 100 of the present embodiment includes a first connection portion 110 and a second heat dissipation pipe 231 connected to an inner surface of the first heat dissipation pipe 231 '. The second connecting portion 130 connected to the inner surface of the plurality of first projections 111 and the second projections 131 formed along the longitudinal direction on the outer peripheral surface of the first connecting portion 110 and the second connecting portion 130 Consists of The nipple 100 is made of metal or plastic material.

The first protrusion 111 and the second protrusion 131 are inclined downward (θ1) (θ2) toward both the centers of the connection parts 110 and 130 (toward the connection termination point at the time of connection). Downward inclined surfaces 111a and 131a are formed. That is, the downward slope 111a and the downward slope 131a are inclined at angles corresponding to each other about the stopper 150 described later.

○ -rings 170 shown in Figs. 1 and 6 are provided on the downwardly inclined surfaces 111a and 131a. Although the ○ -ring 170 also has a sealing function, the combination of adopting the downward slopes 111a and 131a and the ○ -ring 170 of the present embodiment is characterized in that it does not require the use of a tightening mechanism. .

That is, the downwardly inclined surfaces 111a and 131a of this embodiment are inclined in the opposite direction to the conventional upwardly inclined surface 21a. Due to this inclination in the opposite direction, as shown in Fig. 6, when the heat radiation pipes 231 'and 231 are pulled in the direction of the arrow, the ○ -ring 170 is directed toward the larger diameter of the downwardly inclined surfaces 111a and 131a. Going to push up This pushed up ○ -ring 170 rides up to some extent and acts as a wedge, and cannot be easily separated except for forced separation of the heat dissipation pipes 231 'and 231.

It is preferable that the stopper 150 protrudes from the center of the first connecting portion 110 and the second connecting portion 130. The stopper 150 maintains the connection depth between the heat dissipation pipes 230 and 230 '.

On the other hand, in the case where the heat dissipation pipe is soft, as shown in FIG. 7, the first connection part 110 having the downward slope 111a and the second connection portion 22 having the upward slope 21a as in the prior art. The configured nipple 100 'is preferably used. That is, the heat dissipation pipe 231 'is inserted into and connected to the first connection portion 110 by the downward slope 111a and the ○ -ring 170 as described above. The soft pipe is connected and fixed by the inclined surface 21a and the clamp band.

Meanwhile, as illustrated in FIG. 8, the union type nipple 100 of the present embodiment may be used as an elbow type, and may be variously implemented as T, Y, and socket types. The nipples such as elbows may be used when connecting between heat dissipation pipes arranged in parallel. In this case, the nipples may be connected in parallel with the thin pipe or the soft pipe according to the inclined surface.

Such a configuration can be achieved by simply bringing the prefabricated ondol floor to the construction site and inserting the nipple into the heat dissipation pipe and then pushing it (see FIG. 9) to significantly improve workability and workability. In addition, after the ondol floor assembly is connected to the nipple in advance, the construction site can be connected in parallel to the construction.

The ondol floor of the present invention is not limited to the above-described embodiments, and may be variously modified and implemented within the range permitted by the technical idea of the present invention. For example, although the nipple of the present embodiment has been described for connecting a heat radiation pipe of ondol floor, it will be apparent to those skilled in the art that the nipple can be applied to pipe joints other than ondol floor.

As apparent from the above description, the ondol floor of this embodiment has the following effects.

First, by inserting the heat radiation pipe into the groove of the heat insulator, it is possible to pre-assemble the modular operation for each unit of the unit in advance can be carried out by fitting the floor to each unit.

Second, the bottom of the heat dissipation pipe is further formed by the fixing plate is inserted into the groove, it is fixed to dig into the groove of the styrofoam insulation material, and when it is molded into the mortar or soil to be buried in it acts as a reinforcing steel.

Third, both sides of the fixing plate is bent upwardly inclined toward the outside, thereby inducing acceptance into the groove as well as the above-described effect.

Fourth, the inclined surface formed on the projection of the nipple adopts a configuration of a downwardly inclined surface inclined downward from both ends toward the center and a ○ -ring installed on the downwardly inclined surface, without using a separate clamping mechanism such as a clamp band or a nut. It is possible to securely connect and tighten the workmanship, which improves the assembly, and there is almost no connection gap between the pipes, so that unit assembly between short pipes is possible, and the waste of material due to construction can be almost eliminated.

Fifth, the inner diameter of the heat radiation pipe is chamfered, thereby serving as a guide surface for guiding the nipple.
