Description

[Detailed description of the invention] [Technical field to which the invention belongs]

 The present invention is a device in the technical field related to a building board. More specifically, the invention relates to a construction board which can be applied to flooring and wall materials of a building, and particularly has a function of cooling and heating a room by radiant heat.

[Prior art]

 In recent years, flooring and wall materials of buildings have been unitized by building boards, and a pipe for heat exchange medium distribution has been buried inside the building boards to allow the interior of the building to be separated from flooring and wall materials. Techniques for cooling and heating by radiant heat have been proposed (for example, Japanese Utility Model Application Laid-Open No. 56-97323, Japanese Patent Application Laid-Open No. 56-93966). In this case, as shown in FIG. 10, a heat conductive plate-like body 1 such as mortar and the like are used for the building board used in this case in order to effectively use the heat of the heat exchange medium. A plywood structure in which a foamed resin or other heat-insulating plate-like body 2 is disposed on the outside is employed. By the way, when manufacturing such a building board, the heat-insulating plate-like body 2 as a solid formed by forming a heat-insulating material into a plate having a certain thickness in advance is facilitated. 2. A heat conductive material such as mortar is poured in a wet state on the surface of the substrate 2 and dried and hardened, and then the molding frame is removed, whereby the heat conductive plate 1 forming the board surface is replaced with a heat insulating plate. In general, the polymer is formed into a polymer. However, as shown in FIG. 10, when the molding frame is removed, the burrs 3 protrude from the ends of the thermally conductive plate-like body 1 or the chips 4 due to the contact during transportation are often generated. . Therefore, extra work such as the work of removing the burrs 3 and the work of covering the four missing parts with the filling is required, and a relatively large gap a for filling the filling must be provided between the boards. There is a problem that the above appearance deteriorates. In order to solve this problem, it is possible to improve the workability and appearance by preventing the occurrence of burrs and chips, and also to prevent the occurrence of misalignment by preventing warpage and improve the thickness accuracy. In order to provide an architectural board that can be used, a heat insulating material as a solid body formed by forming a heat insulating material into a plate having a certain thickness, and the surface of the heat insulating plate A heat conductive plate made of a heat conductive material that is cast in a wet state and dried and hardened to form a board surface, and a substantially joint surface portion between the heat insulating plate and the heat conductive plate. A board body composed of a tube for distributing a heat exchange medium embedded in the main body, and a peripheral portion of the board body is surrounded and held by an outer frame material having substantially the same height as the entire thickness of the board body. An architectural board with a hanging punch installed almost at the center of the outer frame material body is provided. Use Model Registration No. 2111982).

[Issues to be solved by the invention]

 Certainly, this architectural board can prevent the heat conductive plate from warping, preventing misalignment, improving the thickness and surface accuracy of the board, and adding extra work such as padding work. It is possible to reduce the labor and improve the appearance, and to improve the surface accuracy by preventing the architectural board from being distorted due to the shrinkage action during drying and curing. However, it cannot be denied that this architectural board has difficulty in heat conduction efficiency. In other words, it is difficult to sufficiently retain the cool air or warm air obtained by circulating the heat exchange medium through the pipe body inside the building board, and it is difficult to maintain a certain cooling or heating effect ( There is a drawback that conduction efficiency of warm air or cold air is poor.

[Means for Solving the Problems]

 The present inventors have made intensive studies to solve this problem. As a result, in order to embed the tubular body in the heat-insulating plate, the structure of a groove provided at a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is focused on. The present inventors have found that this problem can be solved by forming a structure that can hold the cooling air or the warm air sufficiently in the groove and efficiently exhibit the cooling effect or the heating effect, and completed the present invention. That is, the present invention provides a heat-insulating plate as a solid formed by forming a heat-insulating material into a plate having a certain thickness, and a wet-casting on the surface of the heat-insulating plate to be dried and cured. A heat conductive plate made of a heat conductive material to form a board surface, and a heat exchange medium for circulating a heat exchange medium buried substantially at a joint surface between the heat insulating plate and the heat conductive plate. A board body consisting of a tubular body of this type, and a peripheral part of the board body is surrounded and held by an outer frame material having substantially the same height as the entire thickness of the board body. In the board, in order to embed the tubular body in the heat-insulating plate, a depth of a groove provided in a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is embedded. It shall be substantially the same as or smaller than the radius of the body, and the cross section of this groove shall be rectangular or trapezoidal. To provide a building board to butterflies.

BEST MODE FOR CARRYING OUT THE INVENTION

 In the present invention, in order to embed the tubular body in the heat-insulating plate, the depth of the groove provided at a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is buried. By making the groove substantially the same as or smaller than the radius of the tube and having a rectangular or trapezoidal cross section, the cool air or warm air obtained by flowing the heat exchange medium through the tube can be transferred to the tube and the groove. And the heat transfer efficiency can be improved more than that of a building board not particularly provided with such a gap, whereby the cooling efficiency or the heating efficiency can be significantly improved. . The depth of the groove is made substantially equal to or smaller than the radius of the tube to be buried by increasing the proportion of the heat conductive plate in the building board according to the present invention as much as possible. The main purpose is to further improve the heat transfer efficiency of this building board. If the depth of the groove is larger than the radius of the tubular body, it is difficult to sufficiently improve the thermal conductivity of the building board, which is not preferable. It is a matter of course that the above-mentioned groove portion needs to have a minimum depth necessary to stably hold the pipe buried in the groove portion. Further, the architectural board according to the present invention is an architectural board which can directly follow the excellent features of the architectural board according to Utility Model Registration No. 2111982. That is, in the architectural board according to the present invention, the board body is surrounded by an outer frame material having substantially the same width as the entire thickness thereof. Casting can be performed, and no burrs or chips are generated. Therefore, there is no need for extra work such as deburring work and filling of the missing parts with filling, and there is no need to leave a gap for filling between the boards. It can be laid, and the appearance can be improved. In addition, the outer frame material also functions as a warp prevention member when the heat conductive plate is dried and shrunk. When a plurality of building boards are laid side by side on a mounting surface such as a floor surface or a wall surface, a step (mesh) is required. Difference) does not occur, and when the board body is fastened to a mounting point on a wall or the like with nails, the fastening strength with nails can be adjusted based on the rising height of the outer frame material. The accuracy of the thickness of the board can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing the configuration of a building board according to this embodiment. The architectural board 10 of the present invention basically includes a heat-insulating plate 11 as a solid body formed by forming a heat-insulating material into a plate having a certain thickness, and the heat-insulating plate 11. A heat conductive plate 12 made of a heat conductive material which is cast on the surface in a wet state and dried and hardened to form a board surface; and a heat insulating plate 11 and a heat conductive plate 12 And a tube 14 for flowing a heat exchange medium, which is buried in a groove 13 having substantially the same depth as the radius of the tube to be buried and having a rectangular cross section at a substantially joint surface portion of the tube. And a peripheral portion of the board body 15 is surrounded and held by an outer frame member 16 having substantially the same height as the entire thickness thereof. As shown in FIG. 1, in this embodiment, the board main body 15 has a plywood structure with a heat-insulating plate 11 joined to one side surface of a heat-conductive plate 12. The material of the heat conductive plate 12 is not particularly limited as long as it has the characteristic of “heat conductivity”, and may be made of, for example, mortar. The raw materials for this mortar are cement, fine sand, fluidizing material, raw incision for heat storage, and early strength material. In addition, the material of the heat-insulating plate-shaped body 11 is not particularly limited as long as it has the characteristic of “heat insulation”, and for example, foamed resin or the like can be used. A groove 13 for inserting and laying the tube 14 is provided on the substantially joint portion side of the heat-insulating plate 11 with the heat conductive plate 12, and the groove is formed as described above. Has a depth substantially the same as the radius of the square, and has a rectangular cross section. The area and the shape of the cross section can be appropriately selected so that the cool air or the warm air sent through the tube 14 can be efficiently held. In this respect, it is desirable that the area of the cross section be as large as possible. On the other hand, in the groove 13, the cross section has a certain area so that the inserted tubular body 14 can be held stably to some extent. It is necessary to set. Further, in the present embodiment, the cross-sectional shape of the groove portion 13 is rectangular, but is not particularly limited as long as the purpose of the present invention, "maintaining sufficient cold or warm air", can be achieved. For example, the trapezoid may be used (the bottom of the cross section may be the short side or the long side of the trapezoid). As described above, a meandering pipe 14 for flowing a heat exchange medium is inserted between the two plate-like bodies 11 and 12 via the groove 13. It is held from the side of the heat conductive plate 12 by a metal mesh material (metal lath) 17 laid on the joint surface of (1). The tube 14 is preferably made of a metal having high corrosion resistance and high thermal conductivity, and is preferably a metal material having a large diameter, a large strength, and a low price. Further, the metal lath 17 is preferably made of a metal net having a high thermal conductivity and a high tensile strength, or a punching metal or the like, and is a material having high flexibility. This metallic glass 17 is fixed to the heat-insulating plate 11 with a fixed needle 17 such as a stapler. The outer frame member 16 surrounding and holding the peripheral edge of the board body 15 is formed in a rectangular frame shape by a highly rigid material, for example, a metal plate material. The outer frame member 16 has substantially the same height as the entire thickness of the board body 15, and preferably also functions as a mold for molding the heat conductive plate 12. That is, when the building board 10 is manufactured, the pipe 14 is inserted and arranged in the groove 13 of the heat-insulating plate-shaped body 11 having the groove 13, and the pipe 14 is covered with the metal lath 17, and then the metal lath 17 is placed. The tube 14 is stopped by the fixed needle 18 for positioning and holding. In this state, the peripheral edge of the heat-insulating plate 11 is surrounded by the outer frame material 16, and the upper edge of the outer frame 16 is projected above the heat-insulating plate 11 to serve also as a forming frame. Mortar, which is a heat conductive material for forming the heat conductive plate 12 in the outer frame material 16 also serving as the forming frame, is cast on the upper surface of the heat insulating plate 11 and the groove 13 side to be cured. The plywood-like architectural board 10 in which the outer frame member 16 surrounds and holds the periphery of the board body 15 is formed. Since the board body 15 is surrounded by the outer frame member 16 having substantially the same width as the entire thickness, even if the heat-conductive plate is dried and shrunk, no warpage occurs. Therefore, as shown in FIG. 2, when a plurality of architectural boards 10 are laid out side by side on the mounting points 19 such as a floor surface or a wall surface, the boards can be installed without any step (unevenness). When the board body 15 is fastened to the mounting portion 19 with the nail 21 or the like, the fastening strength of the nail 20 or the like can be adjusted based on the rising height of the outer frame member 16 as shown in FIG. Since there is no excess or deficiency like the broken line), it is possible to improve the thickness accuracy of the board. Furthermore, since the heat conductive plate 12 can be driven with reference to the height of the outer frame member 16, burrs and the like are less likely to occur, and the peripheral portion of the heat conductive plate member 12 during transport is formed of the outer frame member. Since it is covered with 16, no chipping or the like occurs. Therefore, there is no need for extra work such as deburring work or work for covering a chipped portion with a filling material, and there is no need to provide a space for filling with filling between boards (the gap between the boards is not zero). In addition, it is possible to spread the boards in close contact with each other, and it is also possible to improve the appearance in appearance. If it becomes necessary to handle the board surface, it is possible to apply the outer frame material 16 as a rule so that the appropriateness of the handle thickness can be found immediately, and corrections can be made easily. Can be. However, if the outer frame member 16 is formed in a rectangular frame shape using a flat plate material and only surrounds and holds the periphery of the building board 10, depending on the size and the material of the building board 10, the outer frame member 16 may be formed as shown in FIG. As shown in Fig. 5, there is a possibility that the surface of the building board 10 is distorted at the intermediate portion during drying and curing. Therefore, in order to prevent such distortion, as shown in FIG. 5, a vertical flat plate-like transfer punch 16b is provided at a substantially middle portion of a rectangular frame-shaped outer frame material main body 16a made of a plate-shaped material. As a result, the intermediate portion of the board body 15 is in an adhesively supported state, and a shape preserving effect is provided. Therefore, deformation of the heat conductive plate 12 due to shrinkage during drying and curing is suppressed, and surface distortion is prevented by surface distortion. Accuracy can be improved. In addition, as shown in FIG. 6, a horizontal flat plate-like hanging punch 16c is erected around a substantially middle portion of a rectangular frame-shaped outer frame material main body 16a formed of a flat plate material in the same manner as in the above embodiment. Is also good. Further, as shown in FIG. 7 to FIG. 9, a crossing punch 15e having an inverted T-shaped cross section is provided at a substantially middle portion of a rectangular frame-shaped outer frame material main body 16d formed of an aggregate having an L-shaped cross section. It may be installed. Even with such a configuration, the intermediate portions of the board body 15 are in an adhesively supported state by the hanging punches 16c and 16e, and a shape-retaining effect is imparted. Deformation of the plate-like body 12 is suppressed, and surface accuracy can be improved by preventing surface distortion. In addition, although only one each of the hanging punches 16b, 16c, 16e is shown in the figure, it is needless to say that the number can be set to an arbitrary number.

[Effect of the invention]

 As described above, according to the present invention, in order to embed a tubular body in the heat-insulating plate, a groove provided at a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is provided. By making the depth approximately the same as or smaller than the radius of the pipe to be buried and making the cross section of this groove square or trapezoidal, the cool air or warm air obtained through the pipe can be efficiently used in this groove. It can improve the thermal efficiency of the building board and improve the cooling or heating efficiency of the building board without impairing the excellent features exhibited by the conventional building board. It is possible to do.

 The present invention is a device in the technical field related to a building board. More specifically, the invention relates to a construction board which can be applied to flooring and wall materials of a building, and particularly has a function of cooling and heating a room by radiant heat.

[0002]

[Prior art]

 In recent years, flooring and wall materials of buildings have been unitized by building boards, and a pipe for heat exchange medium distribution has been buried inside the building boards to allow the interior of the building to be separated from flooring and wall materials. Techniques for cooling and heating by radiant heat have been proposed (for example, Japanese Utility Model Application Laid-Open No. 56-97323, Japanese Patent Application Laid-Open No. 56-93966). In this case, as shown in FIG. 10, a heat conductive plate-like body 1 such as mortar and the like are used for the building board used in this case in order to effectively use the heat of the heat exchange medium. A plywood structure in which a foamed resin or other heat-insulating plate-like body 2 is disposed on the outside is employed.

By the way, when manufacturing such a building board, a heat-insulating plate-like body 2 as a solid body in which a heat-insulating material is formed into a plate having a certain thickness in advance is prepared . A heat conductive material such as mortar is poured into the surface of the plate 2 in a wet state and dried and hardened, and then the molding frame is removed, whereby the heat conductive plate 1 forming the board surface is insulated. It is general to polymerize and form the plate-like body 2.

[0004] However, as shown in FIG. 10, when the molding frame is removed, the burrs 3 protrude from the ends of the thermally conductive plate-like body 1 or chippings 4 due to contact during transportation or the like occur. Often. Therefore, extra work such as the work of removing the burrs 3 and the work of covering the four missing parts with the filling is required, and a relatively large gap a for filling the filling must be provided between the boards. There is a problem that the above appearance deteriorates.

[0005] In order to solve this problem, it is possible to improve the workability and appearance by preventing the occurrence of burrs and chips, and to suppress the occurrence of misalignment by preventing warpage and improve the thickness accuracy. The purpose of the present invention is to provide an architectural board that can be designed as a solid body made of a heat-insulating material formed into a plate of a certain thickness, and a heat-insulating plate. A heat conductive plate made of a heat conductive material that is poured into the surface of the body in a wet state and dried and hardened to form a board surface, and the heat insulating plate and the heat conductive plate are roughly described. A board body made of a heat exchange medium distribution tube embedded in the joint surface portion, and a peripheral portion of the board body is surrounded and held by an outer frame material having substantially the same thickness as the entire thickness thereof; The building material is provided by a building board with a hanging punch installed almost in the middle of the outer frame material body. (Utility Model Registration No. 2111982).

[0006]

[Issues to be solved by the invention] Indeed, this architectural board can prevent the heat conductive plate from warping, prevent misalignment, and improve the thickness and surface accuracy of the board. In addition, it is possible to omit extra work such as filling work and improve the appearance, and to improve the surface accuracy by preventing distortion of building boards due to shrinkage during drying and curing. It is now possible. However, it cannot be denied that this architectural board has difficulty in heat conduction efficiency.

[0007] That is, it is difficult to sufficiently retain the cool air or warm air obtained by circulating the heat exchange medium through the pipe body in the building board, and to exhibit a certain cooling effect or heating effect. There is a drawback that the heat (warm air or cold air) conduction efficiency is poor.

[0008]

As a result, in order to embed the tubular body in the heat-insulating plate, the structure of a groove provided at a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is focused on. The present inventors have found that this problem can be solved by forming a structure that can hold the cooling air or the warm air sufficiently in the groove and efficiently exhibit the cooling effect or the heating effect, and completed the present invention.

That is, the present invention provides a heat-insulating plate as a solid formed by forming a heat-insulating material into a plate having a certain thickness, and a wet-casting on the surface of the heat-insulating plate. Heat-conducting plate that is made of a heat-conducting material that forms a board surface after being dried and hardened, and heat exchange buried at the substantially joint surface between the heat-insulating plate and the heat-conducting plate. It has a board body consisting of a tube for media distribution, and surrounds and holds the periphery of the board body with an outer frame material having substantially the same thickness as its entire thickness, and a bridging punch is erected on the outer frame material. In order to embed the tubular body in the heat-insulating plate, the depth of a groove provided at a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is preferably set. The radius of the pipe to be buried is almost the same or shallower than that, and the cross section of this groove is rectangular or trapezoidal. A building board is provided.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION

 In the present invention, in order to embed the tubular body in the heat-insulating plate, the depth of the groove provided at a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is buried. By making the groove substantially the same as or smaller than the radius of the tube and having a rectangular or trapezoidal cross section, the cool air or warm air obtained by flowing the heat exchange medium through the tube can be transferred to the tube and the groove. And the heat transfer efficiency can be improved more than that of a building board not particularly provided with such a gap, whereby the cooling efficiency or the heating efficiency can be significantly improved. .

The reason why the depth of the groove is substantially equal to or smaller than the radius of the tube to be buried is to increase the proportion of the heat conductive plate in the building board according to the present invention as much as possible. The main purpose is to further improve the heat transfer efficiency of this building board. If the depth of the groove is larger than the radius of the tubular body, it is difficult to sufficiently improve the thermal conductivity of the building board, which is not preferable. It is a matter of course that the above-mentioned groove portion needs to have a minimum depth necessary to stably hold the pipe buried in the groove portion.

Further, the architectural board according to the present invention is an architectural board that can directly follow the excellent features of the architectural board according to Utility Model Registration No. 2111982. That is, in the architectural board according to the present invention, the board body is surrounded by an outer frame material having substantially the same width as the entire thickness thereof.

Therefore, there is no need for extra work such as deburring work and filling of the missing parts with filling, and there is no need to leave a gap for filling between the boards. It can be laid, and the appearance can be improved.

Further, the outer frame material also functions as a warp preventing member when the heat-conductive plate-like body shrinks due to drying and shrinking, and when a plurality of architectural boards are arranged side by side on a mounting surface such as a floor surface or a wall surface, There is no step difference, and when the board body is fastened to a mounting point on a wall or the like with nails, the fastening strength with nails can be adjusted based on the rising height of the outer frame material. Therefore, the accuracy of the thickness of the board can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing the configuration of a building board according to this embodiment. The architectural board 10 of the present invention basically includes a heat-insulating plate 11 as a solid body formed by forming a heat-insulating material into a plate having a certain thickness, and the heat-insulating plate 11. A heat conductive plate 12 made of a heat conductive material which is cast on the surface in a wet state and dried and hardened to form a board surface; and a heat insulating plate 11 and a heat conductive plate 12 And a tube 14 for flowing a heat exchange medium, which is buried in a groove 13 having substantially the same depth as the radius of the tube to be buried and having a rectangular cross section at a substantially joint surface portion of the tube. And a peripheral portion of the board body 15 is surrounded and held by an outer frame member 16 having substantially the same height as the entire thickness thereof.

As shown in FIG. 1, in this embodiment, a board body 15 is formed of a plywood structure by a heat-insulating plate 11 joined to one side surface of a heat-conductive plate 12. The material of the heat conductive plate 12 is not particularly limited as long as it has the characteristic of “heat conductivity”, and may be made of, for example, mortar. The raw materials for this mortar are cement, fine sand, fluidizing material, raw incision for heat storage, and early-strength material. In addition, the material of the heat-insulating plate-shaped body 11 is not particularly limited as long as it has the characteristic of “heat insulation”, and for example, foamed resin or the like can be used.

A groove 13 for inserting and laying a tube 14 is provided on a substantially joint portion side of the heat insulating plate 11 with the heat conductive plate 12, and the groove is formed as described above. It has a depth approximately equal to the radius of the body 14 and its cross section is square. The area and the shape of the cross section can be appropriately selected so that the cool air or the warm air sent through the tube 14 can be efficiently held. In this respect, it is desirable that the area of the cross section be as large as possible. On the other hand, in the groove 13, the cross section has a certain area so that the inserted tubular body 14 can be held stably to some extent. It is necessary to set. Further, in the present embodiment, the cross-sectional shape of the groove portion 13 is rectangular, but is not particularly limited as long as the purpose of the present invention, "maintaining sufficient cold or warm air", can be achieved. For example, the trapezoid may be used (the bottom of the cross section may be the short side or the long side of the trapezoid).

As described above, a meandering tube 14 for flowing a heat exchange medium is inserted between the two plate-like members 11 and 12 via the groove 13. The metal mesh material (metal lath) 17 laid on the joint surface of 11 and 12 is held from the heat conductive plate 12 side. The tube 14 is preferably made of a metal having high corrosion resistance and high thermal conductivity, and is preferably a metal material having a large diameter, a large strength, and a low price. Further, the metal lath 17 is preferably made of a metal net having a high thermal conductivity and a high tensile strength, or a punching metal or the like, and is a material having high flexibility. This metallic glass 17 is fixed to the heat-insulating plate 11 with a fixed needle 17 such as a stapler. The outer frame member 16 surrounding and holding the peripheral edge of the board body 15 is formed in a rectangular frame shape by a highly rigid material, for example, a metal plate material.

The outer frame member 16 has substantially the same height as the entire thickness of the board main body 15, and preferably also functions as a mold for molding the heat conductive plate 12. That is, when the building board 10 is manufactured, the pipe 14 is inserted and arranged in the groove 13 of the heat-insulating plate-shaped body 11 having the groove 13, and the pipe 14 is covered with the metal lath 17, and then the metal lath 17 is placed. The tube 14 is stopped by the fixed needle 18 for positioning and holding. In this state, the peripheral edge of the heat-insulating plate 11 is surrounded by the outer frame material 16, and the upper edge of the outer frame 16 is projected above the heat-insulating plate 11 to serve also as a forming frame. Mortar, which is a heat conductive material for forming the heat conductive plate 12 in the outer frame material 16 also serving as the forming frame, is cast on the upper surface of the heat insulating plate 11 and the groove 13 side to be cured. The plywood-like architectural board 10 in which the outer frame member 16 surrounds and holds the periphery of the board body 15 is formed.

However, since the board body 15 is surrounded by the outer frame member 16 having substantially the same width as the entire thickness, even if the thermally conductive plate-like body shrinks due to drying, no warpage occurs. Therefore, as shown in FIG. 2, when a plurality of architectural boards 10 are laid out side by side on the mounting points 19 such as a floor surface or a wall surface, the boards can be installed without any step (unevenness). When the board body 15 is fastened to the mounting portion 19 with the nail 21 or the like, the fastening strength of the nail 20 or the like can be adjusted based on the rising height of the outer frame member 16 as shown in FIG. Since there is no excess or deficiency like the broken line), it is possible to improve the thickness accuracy of the board.

Furthermore, since the heat conductive plate 12 can be driven with reference to the height of the outer frame member 16, burrs and the like are less likely to occur, and the peripheral portion of the heat conductive plate 12 during transportation is hardly formed. Since it is covered with the outer frame material 16, chipping does not occur. Therefore, there is no need for extra work such as deburring work or work for covering a chipped portion with a filling material, and there is no need to provide a space for filling with filling between boards (the gap between the boards is not zero). In addition, it is possible to spread the boards in close contact with each other, and it is also possible to improve the appearance in appearance.

When it becomes necessary to handle the board surface, it is possible to apply the outer frame material 16 as a rule, and it is possible to immediately find out whether or not the handling thickness is appropriate, and to easily make corrections. Can be done.

By the way, simply forming the outer frame member 16 in a rectangular frame shape using a flat plate material and surrounding and holding the periphery of the building board 10 depends on the size and material of the building board 10. As shown in FIG. 4, there is a possibility that the surface of the architectural board 10 may be distorted at the intermediate portion during drying and curing.

Therefore, in order to prevent such distortion, as shown in FIG. 5, a vertical plate-shaped hook is attached to a substantially middle portion of a rectangular frame-shaped outer frame material body 16a made of a plate-shaped material. The intermediate portion of the board body 15 is bonded and supported by the transfer punch 16b, and a shape preserving effect is provided. Therefore, deformation of the heat conductive plate 12 due to shrinkage during drying and curing is suppressed, and surface distortion is caused. Prevention can improve surface accuracy.

As shown in FIG. 6, a horizontal flat plate-like hanging punch 16c is mounted on a substantially middle portion of a rectangular frame-shaped outer frame material body 16a formed of a flat plate material in the same manner as in the above embodiment. May be provided. Further, as shown in FIG. 7 to FIG. 9, a crossing punch 15e having an inverted T-shaped cross section is provided at a substantially middle portion of a rectangular frame-shaped outer frame material main body 16d formed of an aggregate having an L-shaped cross section. It may be installed.

Even with such a configuration, the intermediate portions of the board main body 15 are brought into an adhesively supported state by the hanging punches 16c and 16e, and a shape-retaining effect is imparted. Thus, deformation of the thermally conductive plate-like body 12 due to heat is suppressed, and surface accuracy can be improved by preventing surface distortion. Although only one hook punch 16b, 16c, 16e is shown in the figure, it goes without saying that any number of hooks can be set.

[Effect of the invention]

 As described above, according to the present invention, in order to embed a tubular body in the heat-insulating plate, a groove provided at a substantially joint surface portion of the heat-insulating plate with the heat-conductive plate is provided. By making the depth approximately the same as or smaller than the radius of the pipe to be buried and making the cross section of this groove square or trapezoidal, the cool air or warm air obtained through the pipe can be efficiently used in this groove. It can improve the thermal efficiency of the building board and improve the cooling or heating efficiency of the building board without impairing the excellent features exhibited by the conventional building board. It is possible to do.
