Description

[Technical field]

[0001] The present invention relates to a heat-insulating composite board in which a heat-insulating material is laminated on one side of a plate material such as gypsum board, and to an indoor heat-insulating construction method using the same. [Background technology]

[0002] Conventionally, a thermally insulated composite gypsum board is known in which a thermal insulation material is attached to the other side of a gypsum board. When such a thermally insulated composite gypsum board is used to construct an indoor ceiling, the gap between adjacent thermally insulated composite gypsum boards at the edge portion screwed to the ceiling base material, the rafter, is closed by the rafter. On the other hand, the gap between adjacent thermally insulated composite gypsum boards in the extension direction of the rafter is not closed by the rafter. When a decorative gypsum board is used as the gypsum board to be used as a composite material, no wallpaper is applied, and the gap is not closed by such wallpaper. For this reason, indoor air easily enters the building frame side through the gap, and condensation is easily caused on the building frame side, especially in winter.

[0003] Incidentally, Patent Document 1 discloses a composite heat insulating material in which a foam sheet is bonded to a surface material. At the end of this composite heat insulating material, a portion is formed in which the surface material or the foam sheet becomes a single layer. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-244609 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when a thermally insulating composite gypsum board is produced as described in Patent Document 1, there is a problem in that the decorative gypsum board or the insulating material may be damaged at the single layer of the decorative gypsum board or the insulating material at the end of the thermally insulating composite gypsum board.

[0006] The object of this invention is to provide an insulating composite board in which insulating material is layered over the entire surface of one side of a plate material, and in which a single layer of plate material or insulating material does not appear until immediately before construction, and an indoor insulation construction method using the same. [Means for solving the problem]

[0007] The insulating composite board of the present invention is an insulating composite board in which insulating material is layered over the entire surface of one side of a plate material, and is characterized in that all or part of the insulating material is arranged to be slidable in a certain direction by a guide body fixed to the plate material.

[0008] With the above configuration, when the insulation material is not yet slid, the insulation composite board does not have a single layer of plate material or insulation material. In other words, the insulation composite board does not have a single layer of plate material or insulation material until just before construction, so that the end side of the plate material or insulation material can be prevented from being damaged. On the other hand, during construction, the insulation material slides to overlap the single layer of insulation material and the single layer of plate material at the end side of adjacent insulation composite boards, preventing gaps from occurring at the butt joints of adjacent insulation composite boards and suppressing condensation on the building frame side. In addition, construction of a moisture-proof sheet may also be unnecessary.

[0009] The guide body may be a separate part separated from the heat insulating material, and a part of the heat insulating material may be a slidable part. In this way, the guide body itself has heat insulating properties, and it is possible to avoid a decrease in heat insulating performance.

[0010] The two edges of the insulating material may be used as the separating parts. In this way, the separating parts of the two edges can smoothly guide the slidable part. In addition, in a construction method in which the two edges of the insulating material are screwed to the base material, the separating parts can be simply fixed to the plate material without any problem, which facilitates the production of the insulating composite plate.

[0011] Alternatively, the separating portion may be a portion of the insulating material that is located at the center and has a thickness less than the thickness of the insulating material, which can reduce the number of separating portions to one, thereby facilitating the production of the insulating composite board.

[0012] The entire or a part of each contact surface between the separation portion and the slidable portion of the thermal insulation material may be non-parallel to the thickness direction of the thermal insulation material, and the non-parallel contact surface of the separation portion may face the plate material. In this way, when the thermal insulation material is positioned below the plate material, it is possible to prevent the slidable portion from falling downward.

[0013] The guide body may be a guide member provided separately from the insulating material, and the guide member may support an edge of the insulating material or may engage with a groove formed in the insulating material parallel to the certain direction, so that the entire insulating material can slide. This requires the guide member, but makes it possible to eliminate the step of fabricating the separation portion.

[0014] The slidable portion may have an end detachment portion at one end in the fixed direction so as to be detachable from the slidable portion, or the insulating material which is entirely slidable may have an end detachment portion at one end in the fixed direction so as to be detachable from the insulating material. In this way, the end detachment portion detached at the installation start side of the insulating composite board can be arranged at the non-insulating part of the board part at the installation end side without cutting the insulating material on site.

[0015] The indoor insulation method of the present invention is also characterized by including the steps of sliding all or part of the insulation material in the above-mentioned fixed direction, and overlapping the portion of the plate material that protrudes beyond the end of the insulation material by the sliding with the portion of the insulation material that protrudes beyond the end of the plate material by sliding all or part of the insulation material in the next insulating composite plate. Effect of the Invention

[0016] The present invention has the effect of preventing single-layered areas of plate material or insulating material from occurring in an insulating composite plate in which insulating material is layered over the entire surface of one side of the plate material until immediately before construction, thereby reducing damage to the edges of the plate material or insulating material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. As shown in Figures 1(A), 1(B) and 1(C), a heat insulating composite board 1 of the embodiment has a structure in which a heat insulating material 3 is laminated on the entire surface of the opposite side of a decorative gypsum board (board material) 2, one side of which is decoratively treated.

[0019] The decorative gypsum board 2 is, for example, a ceiling board material with a gyptone pattern, and has dimensions of 9.5 mm thick x 455 mm wide x 910 mm long.

[0020] The heat insulating material 3 is made of, for example, urethane foam, polystyrene foam, or the like, and has a thickness of, for example, 30 mm.

[0021] The heat insulating material 3 comprises a slidable portion 3a provided at the center thereof so as to be slidable relative to the decorative gypsum board 2, and two separation portions 3b located on both edge sides of the slidable portion 3a.

[0022] The slidable portion 3a is not fixed to the decorative gypsum board 2, and slides in a fixed direction (for example, the long side direction of the insulating material 3). On the other hand, the separation portion 3b is fixed to the decorative gypsum board 2 with an adhesive or the like, and functions as a guide body 4 for guiding the slidable portion 3a in the fixed direction. That is, in this embodiment, the guide body 4 is made up of both edges (separation portions 3b) of the insulating material 3. The separation portions 3b can be formed by cutting both edges of the insulating material 3 with a cutter or the like.

[0023] In this embodiment, one end side in the fixed direction of the slidable portion 3a of the heat insulating material 3 is an end detachable portion 3c detachable from the slidable portion 3a. The end detachable portion 3c can also be formed by cutting the end of the heat insulating material 3 with a cutter or the like.

[0024] In the above heat insulating composite board 1, when the slidable portion 3a of the heat insulating material 3 is not slid, the heat insulating composite board 1 does not have a single layer portion of the decorative gypsum board 2 or the heat insulating material 3. For example, as shown in FIG. 2, when the heat insulating composite board 1 is in a stacked state before construction, it is possible to prevent the decorative gypsum board 2 and the heat insulating material 3 from having a single layer portion. This can reduce damage to the edges of the decorative gypsum board 2 and the heat insulating material 3 before construction. On the other hand, during construction, the slidable portion 3a can be slid to form a partial single layer state, as shown in FIG. 3.

[0025] If the guide body 4 is made up of the separated portion 3b separated from the heat insulating material 3, the guide body 4 itself has heat insulating properties, and deterioration of the heat insulating performance can be avoided.

[0026] Furthermore, when the separation portions 3b are positioned on both edges of the heat insulating material 3 (slidable portion 3a), the slidable portion 3a can be smoothly guided by the separation portions 3b on both edges.

[0027] Next, we will explain an indoor insulation method using the above-mentioned heat insulating composite board 1. This method includes a step of sliding the slidable portion 3a, which is a part of the heat insulating material 3, in the above-mentioned fixed direction, and a step of overlapping the portion of the slidable portion 3a of the next heat insulating composite board 1 that protrudes from the end of the decorative gypsum board 2 by sliding the slidable portion 3a with the end of the decorative gypsum board 2 that protrudes from the end of the slidable portion 3a by the above-mentioned sliding.

[0028] As an example, as shown in FIG. 4, when constructing a ceiling, a plurality of heat-insulating composite boards 1 are arranged as ceiling boards in the extension direction of a rough frame (lightweight steel frame base, etc.) 8 assembled on the ceiling side of the room. At this time, for the heat-insulating composite board 1 arranged at the starting end, the sliding part 3a is not slid, and the end detachment part 3c located toward the inside of the room is removed. In this ceiling construction, the heat-insulating composite board 1 is arranged with the decorative gypsum board 2 facing downward, and is fixed to the rough frame 8 by driving a screw into the decorative gypsum board 2 from the room side at the edge side of the heat-insulating composite board 1 where the separation part 3b is located. In a construction method in which the heat-insulating composite board 1 is fastened to the rough frame 8 with a screw, the separation part 3b is fixed to the rough frame 8 by the screw. For this reason, there is no problem even if the separation part 3b is simply fixed to the decorative gypsum board 2 by dot application of adhesive, and the production of the heat-insulating composite board 1 is facilitated.

[0029] Next, the end portion of the decorative gypsum board 2 that protrudes from the insulation material 3 (slidable portion 3a) due to the detachment of the end detachment portion 3c is overlapped with the portion of the insulation material 3 (slidable portion 3a) that protrudes from the end of the decorative gypsum board 2 by the sliding of the insulation composite board 1 to be placed next.

[0030] Thereafter, in the same manner, the end portion of the decorative gypsum board 2 protruding from the insulating material 3 by the above-mentioned sliding of the insulating composite board 1 is overlapped with the portion of the insulating material 3 protruding from the end of the decorative gypsum board 2 by the above-mentioned sliding of the insulating composite board 1 to be placed next.

[0031] Then, for the heat insulating composite board 1 to be placed at the end, the end detachment part 3c detached from the heat insulating composite board 1 placed at the start end is fitted into the non-insulating part on the decorative gypsum board 2 created by the above-mentioned sliding of the heat insulating composite board 1. By providing the end detachment part 3c in this way, the above work can be performed on-site without cutting the heat insulating material.

[0032] In addition, since the above-mentioned furring strips 8 are present at the butt joints of the insulating composite boards 1 arranged in a direction perpendicular to the extension direction of the furring strips 8, the gaps at the butt joints of the insulating composite boards 1 arranged in this manner are filled by the above-mentioned furring strips 8.

[0033] However, as shown in Fig. 5(A) in the above-mentioned heat insulating composite board 1, there is a risk that the above-mentioned slidable portion 3a may come off the heat insulating composite board 1 during transportation or installation. Therefore, the configuration shown in Fig. 5(B) may be adopted for the heat insulating composite board 1. That is, a structure may be used in which the entire contact surface between the separation portion 3b and the slidable portion 3a is non-parallel (inclined) to the thickness direction of the heat insulating material 3, and the contact surface of the separation portion 3b faces the decorative gypsum board 2 at an angle.

[0034] 5(C) may be adopted as the heat insulating composite board 1. That is, a part of each contact surface between the separation part 3b and the slidable part 3a may be non-parallel (orthogonal, etc.) to the thickness direction of the heat insulating material 3, and the non-parallel contact surface part of the separation part 3b may face the decorative gypsum board 2.

[0035] In addition, in the above indoor insulation method, an example of constructing a ceiling using the thermal insulation composite board 1 has been shown, but the present invention is not limited to this, and indoor walls can also be constructed using the thermal insulation composite board 1. That is, when a plurality of sheets of the thermal insulation composite board 1 as a wall board are arranged in the height direction (long side direction), for example, it is possible to prevent gaps from being generated at the butt joints and to prevent the decorative gypsum board 2 or the thermal insulation material 3 from being in a single layer state at the stage before construction. The same applies to the other embodiments described below.

[0036] (Embodiment 2) Next, a heat insulating composite plate according to another embodiment will be described. Fig. 6 shows a heat insulating composite plate 1A according to this embodiment and an example of a method for manufacturing the same. In this manufacturing example, a columnar separation part 3b having a substantially trapezoidal cross section is formed in the long side direction of the center side of the heat insulating material 3, for example, by moving an electric heating wire. This separation part 3b exists with a thickness less than that of the heat insulating material 3. In the heat insulating material 3, the part other than the separation part 3b becomes the slidable part 3a.

[0037] Next, an adhesive is applied to the separation portion 3b, and the decorative gypsum board 2 is laid on the thermal insulation material 3. The decorative gypsum board 2 and the separation portion 3b are integrated by the adhesive, and a thermal insulation composite board 1A is produced in which the separation portion 3b functions as a guide body 4. The thermal insulation composite board 1A also has an end detachment portion 3c at one end in the long side direction of the slidable portion 3a of the thermal insulation material 3, which is detachable from the slidable portion 3a.

[0038] In the heat insulating composite board 1A, the heat insulating material 3 has an upper base on the side of the decorative gypsum board 2, and this upper base is smaller than the lower base, so that each contact surface (parts that become the legs of the trapezoid) between the separation portion 3b and the slidable portion 3a is inclined with respect to the thickness direction of the heat insulating material 3, and the contact surface of the separation portion 3b faces the decorative gypsum board 2 at an angle. If it is difficult to fit the recessed portion of the end detachment portion 3c detached from the heat insulating composite board 1 arranged at the starting end into the separation portion 3b in the non-insulating material portion of the heat insulating composite board 1A arranged at the end, the end detachment portion 3c may be curved to widen the opening side of the recessed portion.

[0039] (Embodiment 3) Next, a heat insulating composite board of another embodiment will be described. As shown in Fig. 7(A), Fig. 7(B) and Fig. 7(C), in the heat insulating composite board 1B of this embodiment, the guide body 4 is composed of four guide members 4A made of, for example, resin, etc., provided separately from the heat insulating material 3. The guide members 4A have a U-shaped cross section, and the opening side faces the inside of the decorative gypsum board 2, and are fixed to the edge of the long side of the decorative gypsum board 2 by adhesive or the like. The guide members 4A are provided away from each end of the decorative gypsum board 2 in the fixed direction. The heat insulating material 3 is supported by the guide members 4A at the edge of its long side and slides in the fixed direction (the long side direction of the heat insulating material 3). Note that the front and back sides of the edge of the long side direction of the heat insulating material 3 are cut to the extent of the thickness of the guide members 4A.

[0040] In the case of the thermal insulation composite board 1B, the entire insulating material 3 is a slidable portion. In addition, since the thermal insulation composite board 1B has a guide member 4A having a U-shaped cross section, it is possible to reduce the risk that the slidable portion 3a will come off the thermal insulation composite board 1 when the thermal insulation composite board 1B is transported or installed. In addition, in the thermal insulation composite board 1B, the thermal insulation material 3, which is entirely slidable, may have an end detachment portion at one end side in the certain direction so as to be detachable from the thermal insulation material 3. In this case, a guide member 4A may be separately provided to lock the end detachment portion.

[0041] (Embodiment 4) Next, a heat insulating composite board of another embodiment will be described. As shown in Fig. 8(A), Fig. 8(B) and Fig. 8(C), in the heat insulating composite board 1C of this embodiment, the guide body 4 is composed of four guide members 4B made of, for example, resin, etc., provided separately from the heat insulating material 3. The guide members 4B have a substantially L-shaped cross section, one half of the L shape is fixed to the decorative gypsum board 2 with an adhesive or the like, and the other half rises obliquely toward the heat insulating material 3. The guide members 4B are provided at a predetermined distance from the end of the decorative gypsum board 2. In addition, two grooves 3d through which the guide members 4B pass are formed in parallel with the fixed direction on the surface of the heat insulating material 3 facing the decorative gypsum board 2. The two guide members 4B in the fixed direction are engaged with the grooves 3d, so that the heat insulating material 3 can slide in the fixed direction relative to the decorative gypsum board 2.

[0042] In the case of the thermal insulation composite board 1C, the entire thermal insulation material 3 is a slidable portion. In addition, in the thermal insulation composite board 1C, the other half of the substantially L-shaped guide member 4B is raised at an angle, so that the slidable portion 3a can be prevented from coming off the thermal insulation composite board 1C during transportation and installation of the thermal insulation composite board 1C. In addition, in the thermal insulation composite board 1C, the thermal insulation material 3, which is entirely slidable, may have an end detachment portion at one end side in the certain direction so as to be detachable from the thermal insulation material 3. In this case, a guide member 4B may be separately provided to lock the end detachment portion.

[0043] Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
