Compared to the existing heat-exchanging panel that uses fire-removing urethane, the light-weight heat-exchanging panel of the present invention uses a board of lightweight non-combustible material such as CRC board or magnesium board as a base layer or a finishing layer, and uses a non-combustible material such as cement. If there is a short circuit on the heating wire, it has the advantage of being safe against fire.

In addition, the lightweight heat transfer panel of the present invention is formed by applying a layered coating to protect the heating wire by mixing non-combustible materials such as silicon or cement and light non-combustible particles on a light weight board such as a CRC board or a magnesium board to form an heat transfer layer and finish. When the layer is made, the overall weight is reduced and the workability is excellent because no additional processing is required on the base layer to arrange the heating wires.

In addition, in the present invention, when the heat transfer layer is formed together with the packing part, a solid finish can be easily performed together with the base layer or the finish layer. Also, light-weight heat transfer panels can be fitted and installed using the packing part.

In addition, the present invention, as a side finishing material of the light weight panel, the packing part may be made into a light weight heat transfer panel fit by making a protrusion or a recess.

In addition, if the packing part is made of a light metal such as aluminum or a constant height material such as plastic, the height of the side surface of the lightweight electric heating panel becomes constant, and when it is made of a concave shape such as "c", it is easily lightweight as a connecting member such as a separate fitting bar It has the advantage of assembling the heat transfer panels.

It has the advantage of protecting the edges or sides.

In addition, when two lightweight boards are bonded with silicone or the like, magnesium boards complement each other when they are bent due to moisture or heating. In addition, since the magnesium board of the finishing layer is insulated and moisture-blocked with silicon of the heat transfer layer, the warp of the base layer is further suppressed, so that the warp of the lightweight heat transfer panel does not occur.

In addition, it can be installed and used as a heating panel or board as a substitute for an indoor stove by attaching it to a wall instead of a gypsum board, and can be individually controlled by a controller. Since it is usually insulated on the outer wall, it can be used as heat transfer and interior when attached to the inner wall. Particularly, instead of the front side, a part of the wall or the floor is installed instead of bricks or partitions, so it can be used in various ways for indoor heating.

The light weight heat transfer panel of the present invention uses a light weight board such as a light magnesium board or a CRC board for one or two layers of a base layer or a finish layer, and forms a heat transfer layer in which heating wires are arranged between the base layer and the finish layer and borders. It is a heat transfer panel with a simple structure that ends with a packing part. Preferred as a lightweight board is a non-combustible material, such as magnesium board, CRC board, or wood panel having similar weight and size to those boards.

It is preferable that the light weight board used in the light weight heat transfer panel of the present invention can be used with a thickness of about 3 mm based on a general CRC board or magnesium board. Also, the base layer and the finishing layer may be made thinner. Therefore, the CRC board is preferable as the lightweight board of the present invention because it is light and easy to handle with a non-combustible material. In addition, since the CRC board is easy to cut in various sizes and has a uniform surface, it can be used as a flooring material or wall material.

Light weight board that can replace CRC board or magnesium board is desirable to have a weight within about 10kg or less than 30% in the same standard compared to 6.5Kg based on 900x1800 x 3mm, which is a typical magnesium board. A board of this weight should be used for ease of handling and construction.

The lightweight heat transfer panel according to the present invention is made by forming an heat transfer layer in which an electric heating wire (or heating wire) is embedded between the base layer and the finishing layer. The heat-transfer layer may be made of a heat-transfer layer in a state in which an electric heating wire is arranged therein using silicon or cement as a main material. In addition, in the present invention, silicon or cement is used as the main material to make the heat transfer layer in which the electric heating wire (or heating wire) is buried. It is lightweight, has a low specific gravity, and is also a non-combustible particle to prevent fire hazard. Volcanic stone, magnesium particle, talc, pearlite (perlite), or plastic beads (bead) or light particles such as granules can be selectively included to support and fix the heating wire. That is, the main material of the heat transfer layer is a material that can withstand the same load as a general flooring material when used as a flooring material and protects the heating wire and is preferably a light material.

Therefore, any material that can be integrally bonded to the inside without damaging the electric heating wire such as a chemical material having good adhesion and waterproof properties such as silicone or urethane or a building material such as cement or mortar can be used. For example, clay or ocher can also be cured by mixing with silicone or cement.

Here, the electric heating wire (heating wire) is preferably a heating wire coated with Teflon or glass fiber.

The heat transfer layer of the present invention may include one or more mesh networks such as glass fibers for strengthening strength, and it is preferable to arrange the two networks above and below based on the electric heating wire. The thinner the thickness of the heat transfer layer, the better, but considering the thickness of the electric wire, it is preferable to make the thickness about 2-4 mm, and preferably about 3 mm.

The packing portion is used to secure the heat transfer layer to the light board, and the thickness can be used to determine the height of the heat transfer layer. Thus, the packing portion may be made of a plastic-based ductile material to prevent the material of the heat transfer layer from flowing down and to be used with a nail or nail to contact with lightweight boards. The packing portion may be used as an aluminum alloy material in consideration of weight to enhance strength, but may be difficult to nail with a nail or nail depending on the thickness. In particular, when the top surface of the packing portion is matched with the side edge portion of the finishing layer, the packing portion has an advantage of protecting and strengthening the strength of the edge of the light weight board or the hard coating layer of the top layer of the finishing layer. In order to protect the edge of the finishing layer of the packing layer, it is preferable to bond the packing portion to the finishing layer, the heat transfer layer, and the base layer by using thick aluminum with enhanced strength.

The electric heating wire can be used for all things that can generate electric heat such as a planar heating element, but it is preferable because a heating wire in the form of a wire such as an electric cable or an electric heating wire can be well combined with the material of the heating layer, and it is particularly preferable to use a waterproofed electric heating cable. good.

The lightweight heat transfer panel of the present invention is based on a wide and thin rectangular parallelepiped shape so that each panel can be easily arranged, and has wiring spaces such as chamfered shapes on the lower two corners to facilitate electrical wiring. In this wiring space part, a wiring protection cover may be combined or arranged side by side. Since the temperature of the heating wire does not exceed 100 degrees, the light weight heating panel can be used in various ways as a wooden board such as plywood.

The lightweight board used in the present invention has less bending or deformation than the magnesium board, and a non-combustible material such as CRC board (Cellulose fiber Reinforced Cement Board) or cement board is preferable as a lightweight board. In particular, CRC board is a substitute for magnesium board, and has good properties such as weight, processability, thickness, and non-combustibility. And when using MDF board or light board of wood, various surface finishes are easy. Especially, when using so-called "reinforced flooring" or wood flooring or solid wood flooring, flooring can be done without additional finishing. Light-weight heat transfer panels can be made by using flooring materials such as reinforced flooring and wood flooring as finishing materials.

The finishing layer can be made by finishing in various conventional methods such as hardwood coating as well as joining or painting veneer to finish the surface of the lightweight board. When considering scratching of a chair or desk as a floor finishing material, a hard coating is preferable, and it is preferable to use a board finished with LPM (Low Pressure Melamine/Laminate) or HPM (High Pressure Melamine/Laminate). CRC board or magnesium board is desirable because it can finish LPM or HPM on the surface.

In addition, the surface hardness of hardwood sheets or finished veneers, such as LPM or HPM coating, can be used as a floor finish, and when it comes into contact with the heat transfer layer based on the packing around the heat transfer layer at the bottom, it replaces the lightweight board and directly over the heat transfer layer. It can be used as a finishing layer. In other words, veneer with sufficient surface hardness and coating thickness, or various coated thin wooden boards or hard coating sheets can be used as a substitute for lightweight boards or wooden boards. When using a thin wooden board or veneer, it is desirable because it has the advantage of being able to make the side thickness between the light-weight heat-transfer panels constant when installed based on the packing.

In addition, various light weight boards described above can be used as the base layer, and a CRC board is preferable as described above. CRC board is good in terms of adhesion or bonding when the lightweight heat transfer panel of the present invention is mainly installed on the cement base. In addition, the base layer can also be used without using a lightweight board is formed of oil or tarpaulin or various waterproofing layer for waterproofing. Particularly, the oil paper is preferable because it has good waterproofness, thinness and sufficient rigidity, but good adhesion with cement or other air masses and bonds.

The lightweight heat transfer panel of the present invention is based on a thin and wide rectangular parallelepiped. The size is not particularly limited, but the length is about 1000 mm-2500 mm, the width is 500-1500 mm, and the height is 5 to 20 mm. It has a good size that can be easily transported and carried by humans. In particular, if it is used as an electric flooring material by installing additionally on an existing floor, the smaller the thickness, the better, so it is recommended to use a CRC board, magnesium board, or wood board with the minimum thickness. It can be made by using, and it is good to make the heat transfer layer thin so that it can support and protect the heating wire and make contact with the top and bottom two layers. As a thin and lightweight heat transfer panel, the bottom base layer is a thin board based on CRC board or magnesium board, and has a thickness of about 3 mm, and the upper finishing layer uses a light board with a thickness of 3 mm or a thinner wood board or plate. It is also possible to use veneer or coating on top of wooden boards or plates. As a thinner and lighter heat transfer panel, the heat transfer layer is formed of a material such as silicon or cement mortar with sufficient strength, and a hardwood veneer directly bonded to the upper part of the heat transfer layer is combined with LPM or HPM finish veneer. Alternatively, it may be used by hard coating directly on the top of the heat transfer layer or by coating with LPM or HPM. In this way, the lightweight heat transfer panel of the present invention is made of a thickness of about 10 mm and can be made within a thickness of about 12 mm. In addition, if the finishing layer is made of thin wood board or the finishing layer is made of veneer or hard coating layer without light weight board, and the heat transfer layer is about 2-3mm, a light heat panel of about 6-9mm can be made. In addition, if the base layer is used as an oil paper without a light weight board, and the heat transfer layer is about 2-3 mm thick, and a light weight board is used for the finishing layer to make 3-4 mm, a light weight heat panel of about 6-9 mm can be made. . However, it may be desirable to use a lightweight board for the finishing layer for even heat transfer to the surface hard coating layer of the finishing layer.

Alternatively, a light board with veneer or hard coating is used for the finishing layer, and the edge of the light board is protected and reinforced by using a packing part with a shorter length at the bottom of the "c" or "c" cross section for the heat transfer layer. To guide and reinforce the support that can distribute the load, and the base layer is made of a lightweight heat transfer panel that can be waterproof and adhere well to the air mass by using an oil paper or a waterproofing layer to make the thickness thinner. Panels can be constructed without gaps by using separate connecting members.

In consideration of productivity, the heat transfer panel of the present invention can be made by using a finishing layer formed by supporting and guiding a heat transfer layer with a packing on its side and attaching a hard-coated veneer to the top. Here, the electric heating wire (or heating wire) of the heat transfer layer is arranged on the lower base layer, and after connecting the electric wires for external electric connection, light particles such as light-weight plastic beads are mixed with silicone or silicone with good adhesion and drying strength. When used, both the bonding strength and the strength of the heat transfer layer can be enhanced. Of course, instead of silicone, a super-fast cement mortar or other materials having different adhesion and strength can form the heat transfer layer.

Hereinafter, the heat transfer block of the present invention will be described in detail with reference to the drawings. CRC board or magnet? Since it is a preferred example of a light weight board, hereinafter, it will be referred to as a light weight board, and description will be mainly focused on the characteristics of the CRC board.

1 is a view showing the inner surface of the lightweight heat transfer panel 100 of the present invention. Light weight heat transfer panel 100 is a light weight board is disposed as a base layer 20 and a finishing layer 50 as a whole, and the packing portion 90 and the power line 10 on the side are visible to the outside, and a normal heat transfer panel is used. It has a similar appearance. The light weight heat transfer panel 100 has the same or similar function as the power supply wire 10 except for the packing portion 90 externally. The packing part 90 is disposed on the entire side surface of the light weight heat transfer panel 100 to support the outer side surface of the heat transfer layer 40 including the power supply line 10 and the heat transfer line 30, and the thickness of the heat transfer layer 40 By making it possible to make it constant, the thickness of the entire lightweight heat transfer panel 100 can be easily made constant.

The main material of the heat transfer layer 40 does not flow well, and the power line 10 or the heat transfer wires 30 may be well disposed on the lower base layer 20, or in a separate process to the appearance of the light weight boards 20 and 50. Light-weighted heat transfer panel 100 may be made without a separate packing portion 90 by stacking and assembling the one in which the heat transfer layer 40 is made to be thin to fit. However, when making the heat transfer layer 40 separately, it is convenient to make the packing portion 90 in a structure that is coupled together around the heat transfer layer 40 in advance.

The packing portion 90 blocks the outer surface of the heat transfer layer 40 and leaves a portion through which the power line 10 can pass. Preferably, all of the external sides except the power line 10 are used. It is to prevent and support.

The lightweight electric heating panel 100 of the present invention is a simple structure in which the power supply wire 10 is connected to the heating wire 30 inside the heating layer 40 for electrical connection with the outside, by the heating of the heating wire 30 The fever is overall.

FIG. 2 is a photograph showing one embodiment of making the light weight panel 100 based on the internal structure of the light weight panel of FIG. 1.

On the base layer 20 or the finishing layer 50, the power line 10 and the heating wire 30 are fixedly arranged with a fixing line 36 on the mesh network 35, and a heat transfer layer 40 material such as silicon or cement mixture Pour the light boards (50, 20) on top and complete them. Thus, a lightweight heat transfer panel 100 is made in the form of a panel. In the present invention, the mesh network (or mesh layer) is preferably made of glass fiber or non-combustible fiber structure. Of course, a metal mesh mesh can also be used, but a glass mesh mesh is preferred when considering weight and convenience of manufacture. The mesh net is not necessarily used, but is preferably used to fix the arrangement of the heating wire 30 or to strengthen the strength of the heating layer 40 and increase resistance to deformation. When the packing portion 90 is disposed at the edge and the heat transfer layer 40 is formed, the height of the heat transfer layer 40 can be made constant.

2, the power cable 10 and the heating wire 30 are connected so as to be waterproof, and a heat transfer layer 40 made of silicon or cement is used as a main material, and a finishing layer 50 is additionally laminated on the heat transfer layer 40. do. At this time, it is preferable that the heat transfer layer 40 is made of a waterproof material, and the power supply wire 10 and the heat transfer wire 30 may be waterproofly connected in various ways using a waterproof tape or the like. If the heat transfer layer 40 itself is made of a material having waterproof performance, for example, it is made to have waterproof performance using waterproof silicone or a similar material, the power cable 10 and the heating cable 30 do not consider waterproofing. And an electrical connection may be sufficient.

3 is a perspective view showing that an example of a packing portion of the lightweight heat transfer panel 100 of the present invention is used. As illustrated, the packing portion 90 has a cross section rotated by 90 degrees in the direction of the heat transfer layer 40. As shown in the light weight panel 100 of FIG. 1, the protruding portion 91 of the packing portion 90 contacts the heat transfer layer 40 and the wide portion 92 contacts the side surface of the light weight panel 100. You can close. Therefore, the thickness of the protruding portion 91 is the same as or the standard of the thickness of the heat transfer layer 40, and the wide portion 92 is thin, and it is preferable to cover the entire side surface of the lightweight heat transfer panel 100. This protects the lightweight board.

4 is a view showing that another example of the packing portion of the lightweight heat transfer panel of the present invention is mounted. As shown, the packing portion 90 has a rectangular cross section of a predetermined thickness, such as an "-". As in the lightweight heat transfer panel 100 of FIG. 1, the protruding portion of the packing portion 90 of FIG. 3 is in the form of a rectangular rod that contacts the heat transfer layer 40 but does not have a wide portion. Therefore, the packing portion 90 does not close the side surfaces of the light weight heat transfer panel 100, and as shown, two adjacent surfaces protrude to the outside of the light weight board 20 and the other adjacent light weight boards (20) It is in a recessed state by going inside. As shown in the figure, the protruding packing portion 90 needs to be secured as much as the protruding width, so it is better that the width of the packing portion 90 is relatively larger than that of the concave packing portion 90. The packing portion 90 of the recessed portion is sufficient to be wide enough to support the heat transfer layer 40, but may be the same width as the packing portion 90 of the projecting portion.

5 is inserted into the space created by the packing portion 90 is disposed so that the rectangular portion of the light-weight heat transfer panel 100, the packing portion 90 of Figure 4 is mounted, the protruding packing portion 90 is recessed Shows that. When the heat-resistant layer 40 is made while the packing portions 90 of two adjacent surfaces protrude from the rectangular lightweight board 20 and the remaining two sides of the packing portion 90 are recessed, as shown in FIG. Can be combined. Of course, it is preferable for the combination that the depth of the recessed packing portion 90 is equal to or greater than the width of the protruding packing portion 90. In this case, it is advantageous in the process that the upper finishing layer 50 is hard-coated on the surface or subjected to a surface treatment such as veneer to eliminate the need for a separate floor or finish. As shown, the lightweight heat transfer panel 100 has a rectangular shape including a square, and is preferable to construct a plurality of light weight heat transfer panels 100 on the floor or wall.

6 is a view showing the inner surface of the lightweight heat transfer panel 100 of the present invention and FIG. 7 is a perspective view of the “c” shaped packing portion 90 and the connecting member 95 of FIG. 6. The difference from the embodiments of FIGS. 1 to 5 is that the upper finishing layer 50' is made of a thinner plate such as veneer without a lightweight board, and the packing portion 90 is made in a "c" shape and It is made of a recessed packing portion 90. Since the light weight heat transfer panel 100 of FIG. 6 uses a recessed "c" shaped packing portion 90, when combined with other light weight heat transfer panels 100 as shown in FIG. 5, the cross section of the'-' type is a rectangular parallelepiped. It is necessary to use a long connecting member 95. The connecting member 95 is convenient if it is cut to the required length and inserted into the recessed portion of the packing portion 90 to be used. Therefore, the thickness of the connecting member 95 may be equal to or smaller than the width of the depression. The connecting member 95 is made of metal, wood, or plastic, and may be suppressed so that the lightweight heat transfer panels 100 are not lifted or separated.

The lightweight heat transfer panel 100 provided with a “U” shaped packing portion 90 uses both a light weight board for the base layer 20 and the finishing layer 50, or as shown in FIG. 6, the finishing layer 50' is thick. A thin thin layer of veneer or a hard coat sheet may be used. At this time, the veneer or coating layer is thinner than the existing lightweight board, but it is preferable to have strength and hardness to the extent that it can withstand the friction and scratches of life, especially in the case of the floor. For this purpose, it is recommended to finish the veneer with LPM (Low Pressure Melamine/Laminate) or HPM (High Pressure Melamine/Laminate). Unlike hard coating on a lightweight board, the thin finish layer 50' can be easily constructed by attaching or combining hard coated sheets such as LPM or HPM on the heat transfer layer 40, as well as hard coated sheet paper or veneer.

The finishing layer 50' has a specific pattern such as veneer and has a good LPM or HPM hard-coated sheet shape, and has a high thermal conductivity, such as aluminum foil or thin thin metal layer, and a thin, thin heat diffusion layer. It is preferred to place it under layer 50'. In particular, the heat diffusion layer prevents heat from the heat transfer line 30 from being directly and locally rapidly transferred to the veneer or sheet paper of the finishing layer 50', and is evenly distributed throughout the finishing layer 50'. Thus, there is an advantage in that no heating traces such as arranging the heating wire 30 on the hard coating layer or the veneer are left and the heating temperature is lowered to save energy. A new metal layer with good thermal conductivity is added as a heat diffusion layer. The heat diffusion layer may be evenly attached to the bottom of the finishing layer 50', or may be attached to cover the heating wire 30. In addition to the thin finishing layer 50', the heat diffusion layer may be added to the finishing layer 50 in which a lightweight board is used. However, in the case of the finishing layer 50 using a light weight board, the heat conduction of the heat of the heating wire 30 is substantially made by the light weight board, and the heat diffusion layer has a thin effect compared to the process or components added for the heat diffusion layer ( It's not as good as 50').

The lightweight heat transfer panel 100 provided with a “U” shaped packing portion 90 can be easily coupled to the floor or wall using a connecting member 95, as well as a heat transfer partition like a conventional partition. It also has the advantage of being easy to install. As shown in FIG. 7, it can be used as a plastic or aluminum chassis material so that it can be cut and used as long as necessary. The packing portion 90 of FIG. 7 shows that a space 94 through which the power line 10 passes is provided. The space 94 for the power line 10 may be made by cutting a part of the packing portion 90 as necessary.

8 is a view showing that a space for connecting a power line is made to the lower light weight board of the light weight panel of the present invention. A wiring space portion 29 may be formed in the lower base layer 20 in a chamfered form on both corners of a narrow width. Thus, a cover (not shown) for protecting the electrical wiring may fill the wiring space portion 29. In this case, the packing portion 90 should be provided with a space 94 for the power line 10 to pass, or the packing portion 90 should be closed as much as the space portion. In the example of FIGS. 4 to 6, the packing part 90 completely surrounds the heat transfer layer 40, but may be arranged with a space other than a closed space to secure a space for wiring or a required part during the operation.

In addition, the heat transfer layer 40 may be additionally arranged with a support portion 41 made of the same material as the packing portion 90 or a harder material. That is, when the same as the packing section 90 of the rectangular cross section of FIG. 4 on the light weight board is disposed between the heating wires 30, it is easy to arrange and fix the heating wires 30 and the load from the surface of the finishing layer is further added to the heating layer 40. It can disperse well and withstand. Particularly, when forming the heat transfer layer 40 as a resin-based material, it is preferable to use a support portion for load distribution.

In the lightweight heat transfer panel 100 of the present invention of Figure 1 above, the heat transfer layer 40 is combined with the finishing layer 50 of the light weight board on the top. It has been described that a thin finishing layer 50' of a veneer or a coating layer can be formed instead of a lightweight board, and it is possible to construct the lightweight heat transfer panel 100 of the present invention as a flooring material without additional finishing work. It is good for strength reinforcement when used.

9 is a view showing that the support is used for the heat transfer layer 40. It shows that the heating wire 30 and the power line 10 are arranged by arranging rod-shaped support portions 41 having rectangular cross sections of various sizes on the finishing layers 50 and 50' or the base layer 20. As shown in the figure, the heating wire 30 and the power wire 10 are arranged between the support parts 41, and materials such as silicon to form the heating layer 40 are applied and the finishing layers 50 and 50' below or The base layers 20 and 20' or the finishing layers 50 and 50' are bonded on top to correspond to the base layer 20. Of course, the finishing layers 50 and 50' of the floor or the base layer 20 may also be well bonded by applying the support portion 41, the heating wire 30, and the power wire 10 with an adhesive such as silicone. Here, the thickness of the support portion 41 is preferably to have a larger thickness than the heating wire 30 and the power supply wire (10). In addition, since the packing portion 90 of the rim is used as the same material with the same thickness as the supporting portion 41, the supporting portion 41 and the packing portion 90 can evenly distribute the load, and also the entirety of the lightweight heat transfer panel 100. There is an advantage that the thickness becomes constant. In FIG. 9, the packing portion 90 of the rim may serve as the recessed packing portion 90 of FIGS. 4 and 5. In this case, since all of the depressions in FIG. 9 are used, the connection member 95 of FIG. 7 can be used as the “c” shaped packing portion 90. When a separate “U” shaped packing portion 90 is not used, a light weight board is used as the finishing layer 50 and it is preferable to finish it with a veneer. This is because, when the finishing layer 50' is formed of a thin wooden board, a veneer, or a coated paper without a lightweight board, it is disadvantageous in supporting the edge of the finishing layer 50'. Therefore, in the example of FIG. 9, when the “c” shaped packing portion 90 is disposed on the rim, the lightweight heat transfer panel 100 of the present invention can be made only of a veneer or hard coating layer without using a lightweight board. Of course, even if the "c" shaped packing portion 90 is used, if both the lightweight board and the coating layer are used for the finishing layer 50, it is possible to protect the edge of the heat transfer layer 40 and the edge of the lightweight board.

10 shows that the heating wire 30 and the power line 10 are disposed between the support parts 41. In FIG. 10, the support portions 41 are disposed close to each other, leaving a minimum space for accommodating the heating wire 30. When the support portion 41 occupies a lot of space in the heat transfer layer 40, it also serves to distribute the load applied to the light weight heat transfer panel 100 evenly to the base layer 20, but it is relatively more expensive than expensive materials such as silicon. It is also possible to make the support portion 41 of this cheap wood or plastic or lightweight board material has the advantage of lowering the manufacturing cost of the entire lightweight heat transfer panel 100.

11 is a view showing another example of the support. In FIG. 11, the packing portion 90 is disposed on the rim of the four sides, and the support portion 41 is disposed such that the heating wire 30 and the power supply wire 10 can be wired, and additional wire support portions ( 45) is inserted so that the height of the heating wire 30 and the power line 10 is constant. The electric wire support portion 45 for supporting electric wires such as electric heating wires is used so that the electric heating wires 30 and the power wires 10 can be wired at regular intervals between the base layer 20 and the finishing layers 50 and 50'. will be. In FIG. 11, the wire support 45 may be arranged in either the finishing layers 50 and 50 ′ or the base layer 20 and may be determined in consideration of workability. However, when using the thin-type finishing layer 50', it is advantageous in terms of heat distribution or support strength of the heating wire 30 that the wire support 45 is disposed on the finishing layer 50'. The support portions 41 are in the form of a number of elongated plate members arranged at predetermined intervals so as to form a portion through which the heating and power lines pass, or the supporting portion 41 forms a portion through which the heating and power lines pass. Arranged at predetermined intervals, an additional wire support 45 is further disposed to support the heating wire 30 and the power line 10 between the support portions 41, or the support portion 41 and the wire support portion 45 may be formed in a combined form or integrally.

The support portions 41 and 45 used in the heat transfer layer 40 need not be particularly limited in shape, but only need to have a constant height. Preferably, the rod shape of a rectangular cross section is convenient as shown in the packing portion of FIG. 4. The wire support 45 only needs to be sized so that its height and size fit between the support parts 41. The material of the support parts 41 and 45 can be used as long as it is made of a rod shape and can withstand the load, but wood, plastic, and lightweight board pieces can be used to reduce weight and reduce costs.

In addition, the support portions 41 and 45 used in the heat transfer layer 40 may be separately manufactured in one piece in advance to manufacture the light weight heat transfer panel 100. In particular, if it is made of heat-resistant plastic, it can be easily made of injection material, and when it is made by mixing various materials such as stone powder or ocher with heat-resistant plastic, it can be heated evenly by the heating wire 30 to exhibit an ondol effect.

In the case of using the support portion 41 as shown in FIG. 11, a more robust coupling can be made by additionally driving a nail or a screw with a lightweight board. Particularly, since the width of the support portion 41 is wide, when the support portion 41 is coupled in the direction of the light board, the position of the electric wire can be easily checked and avoided. Bonding can be strengthened by nailing the edges and the center. Of course, the lightweight board and the packing portion 90 can also be taken out with a nail. When using a strong metal to increase the strength of the packing portion 90, it is better to use a tab or nail. If a soft metal is used as the packing portion 90, a screw or the like may be used. In this case, it is also good to make a packing portion 90 by securing a space for a screw or the like in the packing portion 90 in advance. That is, if the width of the heat transfer layer 40 is widened in the packing portion 90 of the “C” cross section and an empty space is created within the width, it can be easily combined with a lightweight board with screws or the like, and also with the connecting member 95 Interference may not occur. That is, it is possible to make the packing portion 90 in the shape of a cross-section in which the “ㅂ” shape is rotated 90 degrees.

12 is a view showing that the lightweight heat transfer panels 100 are connected to each other using a connecting member 95. In FIG. 12, the two light-weight heat transfer panels 100 arranged side by side insert the long rod-shaped connecting member 95 having a rectangular cross section between the “c”-shaped packing parts 90 so that the light weight heat transfer panels 100 cannot lift each other. Make sure to combine well. In FIG. 12, the “c” shaped packing portion 90 is used and the thin finishing layer 50 ′ is used as an example, but the rectangular rod packing portion 90 of FIG. 4 has a base layer 20 and a finishing layer 50. If it is arranged so as to be recessed inside the rim, the "c" shaped packing portion 90 is used as a whole, and when the finishing layer 50 using a light weight board is used, the connecting member as shown in the light weight panel 100 of FIG. 12 Light weight heat transfer panel 100 may be connected using (95). The connection method of the lightweight heat transfer panel 100 of FIG. 12 can be used as a construction method as a floor heat transfer panel, but can be used in the same way on the wall surface.

13 is a view showing a cross section of a lightweight heat transfer panel as another preferred embodiment of the present invention. Looking at the layer structure, the finishing layer 50 includes a lightweight board and a hard coating layer for finishing. And the heat transfer layer 40 is a support portion 41 and a "c" shaped short packing portion 90 is used. In addition, the base layer 20' is made of oil paper, so that the light-heating panel is well adhered to the bases of the waterproofing and the cement floor. In particular, when the lower end of the packing portion 90 is short and the base layer 20' is made smaller and smaller than the finishing layer in accordance with the lower end of the packing portion 90, a space for connecting a power line is created at the lower portion, thereby simplifying construction. . In addition, the wiring space portion 29 formed at both edges of the light weight board of the base layer 20 of FIG. 8 may not need to be formed in the light weight heat transfer panel 100 of FIG. 13. If the width of the lower portion of the packing portion 90 is narrow, the operation for wiring may be more convenient.

In the example of FIG. 13, the packing portion 90 has a shape in which the lower portion has a narrow width in a “c” shape, so that the widths of the upper side and the lower side of the packing portion 90 are different. Therefore, if the rim of the finishing layer 50 is matched according to the upper edge of the packing portion 90, and the rim of the base layer 20' is matched according to the narrow edge of the lower side, the finishing layer ( The area of 50) is different from that of the base layer 20', and the area of the finishing layer 50 is wider. So, the wiring connection of the power line 10 between the light-weight heat transfer panels 100 can be facilitated. The advantage of this embodiment is that there is a light weight board on the heating wire 30 so that heat is evenly distributed and transferred to the top of the finishing layer 50, and the base layer 20' is thin, so that the thickness of the entire light heating panel 100 is about 10 mm or so. It becomes thin. Therefore, when building the floor, the height of one floor of the building can be lowered and the existing floor can be installed without completely removing it. In addition, in this embodiment, the light weight board of the finishing layer 50 has a hard coating layer coupled to the front surface at the top, and a packing portion 90 coupled to all edges at the bottom to form the edges and corners of the light weight board having a brittle or fragile property. It has the advantage of being well protected. As a result, the edges or edges of the lightweight board are well tolerated even under moderate impact.

14 is a perspective view showing various embodiments of the packing portion 90 of the present invention.

FIG. 14(a) shows a cross section of a shape in which the lower portion, that is, the base layers 20 and 20', of the “c” shape of the packing portion 90 is shorter, and FIG. 14(b) shows the packing portion 90. In the "ㅂ" shape of, the base layer 20, 20' side shows a shorter shape cross section. The "ㅂ" type has a hollow part {97} when a metal packing part 90 such as aluminum is used, so that a screw is easily inserted through a lightweight board, and also acts as a support part 41 at the rim. There is an advantage that can be performed. As described above, the packing portion 90 of the present invention can be used in the lightweight heat transfer panel 100 in various shapes.

In the above, the appearance and the internal structure of the lightweight heat transfer panel 100 of the present invention are mainly described, and the main components will be described in more detail below.

First, a part of the heat transfer layer 40 is buried and the power line 10 connected to an external power source can be used with existing electric wires. However, in the present invention, it is buried in silicon or cement mortar, so it can withstand water resistance and cement well. It is preferred that the wire is coated with a material.

In addition, the electric heating wire 30 connected to the power line 10 can be used by various existing electric heating elements, but is also embedded in cement, so an electric heating wire coated with a material that can withstand water resistance and cement is good. In addition, since the heat is generated, a heating wire coated with Teflon or glass fiber is better than a polymer or plastic coating on the wire.

As a material for forming the heat transfer layer of the present invention, a component having good adhesion and strength, such as a polyurethane-based urethane-based resin such as silicone-based or resin-based, may be used. For example, a polyurethane-based sealant such as Koresil PU9330 from KCC Corporation can be used.

In addition, a material formed by mixing the cement-based component and/or clay-based component with the non-combustible lightweight particles may be used as a material for forming the heat transfer layer. The cement-based component is a general cement or cement mortar, cement concrete, as well as a reinforced cement having a stronger strength than ordinary cement, a super hard cement (or super hard mortar) that hardens faster than ordinary cement, or a cement mortar with a fluidizing agent added One or more self-leveling cement mortars are used, and the clay-based components use any one or more of clay, ocher, aggregate particles, and plaster particles, and the lightweight particles are non-combustible materials such as plastic particles, volcanic stones, magnesium particles, talc, pearlite (perlite) The use of one or more particles. It is recommended to use reinforced cement or super hard cement that is strong and does not break well, or includes one or more automatic mortars, such as self-leveling mortar. The preferred cemented carbide is a composition prepared by mixing the main material and water in a weight ratio of 1:0.2 to 0.215, wherein the main material is 25 to 28 parts by weight of ordinary Portland cement, 5 to 10 parts by weight of alumina cement, and 8 to 11 of anhydrous gypsum. Weight parts, fine aggregate 43~47 parts by weight, inorganic filler 5-8 parts by weight, antifoaming agent 0.1-2 parts by weight, thickener 0.001~0.2 parts by weight, curing accelerator 0.001~0.04 parts by weight, fluidizing agent 0.01~0.5 parts by weight, condensation delay It can be made to contain 0.01 to 0.3 parts by weight, 1 to 5 parts by weight of polymer synthetic resin. Such a super hard cement can be manufactured according to the content of Korean Patent No. 10-1066298 as an example. And so-called automatic mortar can be used, which is called self-leveling mortar, and can be seen on an indefinite material having a property of flattening the surface just by pouring it. It is a cement mortar obtained by adding a fluidizing agent in cement mortar, etc. .

In addition, the reinforced cement includes a first conventional mineral component and a second component based on powdered slaked lime, and the second component based on powdered slaked lime is less than 12 m2/g, calculated according to the BET method, Advantageously those having a specific surface area of less than 11 m2/g, in particular less than 10 m2/g, preferably less than 9 m2/g can be used. Self-leveling cement mortar is prepared by mixing the base material and the emulsion in a weight ratio of 1:0.2 to 0.3, and the base material is 28 to 33 parts by weight of ordinary Portland cement, 5 to 10 parts by weight of alumina cement, 5 to 8 parts by weight of anhydrous gypsum, Fine aggregate 40~45 parts by weight, inorganic filler 10~15 parts by weight, antifoaming agent 0.1~2 parts by weight, thickener 0.001~0.2 parts by weight, curing accelerator 0.001~0.05 parts by weight, fluidizing agent 0.01~0.5 parts by weight, condensation retardant 0.01~ 0.3 parts by weight, the emulsion may be used that contains 48 to 52 parts by weight of water, 47 to 51 parts by weight of acrylic resin, 0.1 to 1 part by weight of an antifoaming agent. Alternatively, the self-leveling cement mortar is mixed with the main material and water in a weight ratio of 1:0.2 to 0.215, and the main material is 25 to 28 parts by weight of ordinary Portland cement, 5 to 10 parts by weight of alumina cement, 8 to 11 parts by weight of anhydrous gypsum, fine aggregate 43 to 47 parts by weight, inorganic filler 5 to 8 parts by weight, antifoaming agent 0.1 to 2 parts by weight, thickener 0.001 to 0.2 parts by weight, curing accelerator 0.001 to 0.04 parts by weight, fluidizing agent 0.01 to 0.5 parts by weight, condensation retardant 0.01 to 0.3 It can be used to include 1 part by weight, 1 to 5 parts by weight of a polymer synthetic resin. Various materials using the existing cement as above can be used to form the heat transfer layer.

In addition, although not shown in detail in the drawings, the heat-transfer layer may contain light-weight particles as inorganic non-combustible particles such as light-weight pearlite, 100-300 grams of the above based on 1 kg of silicone or urethane-based resin or cement clay-based component. It is good to include non-combustible lightweight particles, and it can be mixed with an appropriate amount of water and poured into a mold so that the mixture can be well cured. In an appropriate amount, about 3-4 liters are good for blocking when considering curing time. Here, the lightweight particles are light particles that are non-combustible and need to be well mixed with the main material and smoothly surfaced. The light-weight particles of the present invention, pearlite is the most preferable in nature, but can be used as one or more of plastic particles, volcanic stone, magnesium particles, talc, perlite particles, and various inorganic particles as non-combustible materials.

In addition, the heat-resistant plastic material in a slightly higher temperature than room temperature, such as ultraviolet curing, such that the electric heating wire can be integrally combined to make a heat transfer layer.

Preferably, it is insulated on the floor and the arrangement and wiring of the lightweight heat transfer panel 100 of the present invention is completed. If there is no finishing layer, it is used as a variety of existing finishing materials such as reinforcing floors, decor tiles, vinyl flooring, etc. Final deadline. In addition, when the lightweight heat transfer panel 100 of the present invention is disposed on a wall such as a gypsum board, it can be used by final finishing with wallpaper.

In particular, when used on a wall, when using an heat transfer block having a finishing layer, there is an advantage that it can be more easily finished without a finishing material.
