Description

The present invention relates to a heat insulating composite board in which a heat insulating material is superposed on one side of a board material such as a gypsum board, and an indoor heat insulating method using the heat insulating composite board.

Conventionally, a heat insulating composite gypsum board in which a heat insulating material is bonded to the other side of the gypsum board has been known. When constructing an indoor ceiling using such a heat-insulating composite gypsum board, at the edge portion screwed to the field edge, which is the ceiling base material, the butt gap between adjacent heat-insulating composite gypsum boards is the above-mentioned field edge. Will be blocked by. On the other hand, the portion of the butt gap between the heat insulating composite gypsum boards adjacent to each other in the extending direction of the field edge is not closed by the field edge. When a decorative gypsum board is used as the gypsum board as a composite material, the cloth is not pasted, so that the gap is not closed by such cloth pasting. Therefore, the air in the room easily enters the building skeleton side through the above gap, and dew condensation is liable to occur on the building skeleton side particularly in winter.

By the way, Patent Document 1 discloses a composite heat insulating material in which a foam sheet is bonded to a surface material. At the end of the composite heat insulating material, a portion where the surface material or the foamed sheet becomes a single layer is formed.

However, when the heat insulating composite gypsum board is manufactured as in Patent Document 1, the decorative gypsum board or the heat insulating material is damaged at the single layer portion of the decorative gypsum board or the heat insulating material at the end of the heat insulating composite gypsum board. There's a problem.

The present invention is a heat insulating composite board in which a heat insulating material is laminated on the entire surface of one side of the board material, and a heat insulating composite board capable of preventing a single layer portion of the board material or the heat insulating material from occurring until immediately before construction, and an indoor heat insulating method using the same. The purpose is to provide.

The heat insulating composite plate of the present invention is a heat insulating composite plate in which a heat insulating material is laminated on the entire surface of one side of the plate material, and all or a part of the heat insulating material can be slid in a certain direction by a guide body fixed to the plate material. It is characterized by being provided in.

With the above configuration, in the non-sliding state of the heat insulating material, the heat insulating composite board does not have a single layer portion of the plate material or the heat insulating material. That is, since the plate material or the single layer portion of the heat insulating material in the heat insulating composite board can be prevented from being generated until immediately before the construction, it is possible to prevent the plate material and the end side of the heat insulating material from being damaged. On the other hand, at the time of construction, the slide of the heat insulating material overlaps the part of the single layer heat insulating material and the part of the single layer plate material on the end side of the adjacent heat insulating composite boards, and there is a gap at the abutting point of the adjacent heat insulating composite boards. Can be prevented from occurring and the occurrence of dew condensation on the building frame side can be suppressed. In addition, the construction of a moisture-proof sheet may be unnecessary.

The guide body may be a separated portion separated from the heat insulating material, and a part of the heat insulating material may be a slideable portion. According to this, the guide body itself also has a heat insulating property, and it is possible to avoid deterioration of the heat insulating performance.

Both edges of the heat insulating material may be used as the separating portion. According to this, the slidable portion can be smoothly guided by the separated portions of both edges. Further, in the construction method in which both edges of the heat insulating material are screwed to the base material, there is no problem even if the separated portion is simply fixed to the board material, so that the manufacturing of the heat insulating composite board can be facilitated. I can plan.

Alternatively, a portion on the central side of the heat insulating material and less than the thickness of the heat insulating material may be used as the separating portion. According to this, since the number of the separated portions can be reduced to one, it is possible to facilitate the production of the heat insulating composite plate.

All or part of each contact surface between the separation portion and the slidable portion of the heat insulating material is non-parallel to the thickness direction of the heat insulating material, and the non-parallel contact surface of the separation portion. May face the plate material. According to this, it is possible to prevent the slidable portion from falling downward in the posture in which the heat insulating material is located below the plate material.

The guide body is composed of a guide member provided separately from the heat insulating material, and the guide member supports the edge side of the heat insulating material or is formed in a groove formed in the heat insulating material in parallel with the fixed direction. All of the insulation may be engaged and slidable. According to this, although the guide member is required, the step of manufacturing the separated portion can be eliminated.

The slidable portion has an end detachable portion that can be detached from the slidable portion on one end side in the fixed direction, or the heat insulating material that is all slidable in the constant direction. An end detachment portion may be provided on one end side so as to be detachable from the heat insulating material. According to this, the end detached portion detached at the installation start side of the heat insulating composite plate is arranged at the non-insulated material portion of the plate portion on the installation end side without cutting the heat insulating material at the site. be able to.

Further, in the indoor heat insulating method of the present invention, the step of sliding all or a part of the heat insulating material in the above-mentioned fixed direction and the heat insulating portion of the plate material protruding from the end of the heat insulating material by the sliding are heat-insulated in the next heat insulating composite board. It is characterized by comprising a step of superimposing a portion of the heat insulating material protruding from the end of the plate material by sliding all or a part of the material.

According to the present invention, in a heat insulating composite board in which a heat insulating material is superposed on one surface of a board material, a single layer portion of the board material or the heat insulating material is prevented from being generated until immediately before construction, and the end side of the board material or the heat insulating material is prevented. It has the effect of reducing the damage caused by.

It is a plan view.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 (A), 1 (B) and 1 (C), the heat insulating composite board 1 of the embodiment has the entire surface of the opposite side of the decorative gypsum board (plate material) 2 having a decorative treatment on one side. It has a structure in which the heat insulating material 3 is superposed.

The decorative gypsum board 2 is, for example, a ceiling board material having a zip tone pattern, and has a size of 9.5 mm in thickness × 455 mm in width × 910 mm in length.

Further, the heat insulating material 3 is made of, for example, urethane foam, polystyrene foam, or the like, and its thickness is 30 mm or the like.

The heat insulating material 3 includes a slidable portion 3a provided slidably with respect to the decorative gypsum board 2 on the central side, and two separating portions 3b located on both edge sides of the slidable portion 3a.

The slidable portion 3a is not fixed to the decorative gypsum board 2 and slides in a certain direction (for example, the long side direction of the heat insulating material 3). On the other hand, the separating 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 composed of both edges (separation portions 3b) of the heat insulating material 3. The separation portion 3b can be formed by cutting both edges of the heat insulating material 3 with a cutter or the like.

Further, in this embodiment, one end side of the slideable portion 3a of the heat insulating material 3 in the fixed direction is an end detachable portion 3c that can be detached from the slidable portion 3a. The end detaching portion 3c can also be formed by cutting the end of the heat insulating material 3 with a cutter or the like.

In the case of the heat insulating composite board 1, in the non-sliding state of the slidable portion 3a in the heat insulating material 3, the heat insulating composite board 1 has a single layer portion of the decorative gypsum board 2 or the heat insulating material 3. not. For example, as shown in FIG. 2, it is possible to prevent the single layer portion of the decorative gypsum board 2 and the heat insulating material 3 from being generated in the stacked state of the heat insulating composite board 1 before construction. As a result, it is possible to reduce damage to the edges of the decorative gypsum board 2 and the heat insulating material 3 before construction. On the other hand, at the time of construction, as shown in FIG. 3, the slidable portion 3a can be slid to form a partially single-layer state.

When the guide body 4 is composed of a separating portion 3b separated from the heat insulating material 3, the guide body 4 itself also has a heat insulating property, and deterioration of the heat insulating performance can be avoided.

Further, when the separating portion 3b is located at both edges of the heat insulating material 3 (sliding portion 3a), the sliding portion 3a can be smoothly guided by the separating portions 3b of both edges.

Next, an indoor heat insulating method using the heat insulating composite plate 1 will be described. In this method, the slideable portion 3a, which is a part of the heat insulating material 3, is slid in the fixed direction, and the following is applied to the end portion of the decorative gypsum board 2 protruding from the end of the slideable portion 3a by the slide. It includes a step of superimposing a portion of the slidable portion 3a protruding from the end of the decorative gypsum board 2 by sliding the slidable portion 3a of the heat insulating composite plate 1.

As an example, as shown in FIG. 4, when constructing a ceiling, a heat insulating composite plate as a ceiling board is provided in the extending direction of a field edge (lightweight steel frame base, etc.) 8 assembled on the ceiling side of the room. Arrange a plurality of 1's. At this time, for the heat insulating composite plate 1 arranged at the start end, the slideable portion 3a is not slid, and the end detaching portion 3c located in the inner direction of the room is removed. In this ceiling construction, the heat insulating composite board 1 is arranged with the decorative gypsum board 2 facing down, and the fixing to the field edge 8 is performed from the indoor side on the edge side of the heat insulating composite board 1 where the separation portion 3b is located. This is done by driving a screw into the board 2. In the construction method in which the heat insulating composite plate 1 is fastened to the field edge 8 with screws, the separation portion 3b is fixed to the field edge 8 by the screws. Therefore, there is no problem even if the separation portion 3b is simply fixed to the decorative gypsum board 2 by spotting an adhesive, and the heat insulating composite plate 1 can be easily manufactured.

Next, the slide of the heat insulating composite plate 1 to be arranged next on the end portion of the decorative gypsum board 2 protruding from the heat insulating material 3 (sliding portion 3a) by separating the end detaching portion 3c. The portion of the heat insulating material 3 (sliding portion 3a) protruding from the end of the decorative gypsum board 2 is overlapped.

After that, similarly, the slide of the heat insulating composite board 1 protrudes from the edge of the decorative gypsum board 2 overhanging from the heat insulating material 3, and the slide of the heat insulating composite board 1 to be arranged next protrudes from the end of the decorative gypsum board 2. Overlap the parts of the heat insulating material 3.

Then, regarding the heat insulating composite plate 1 arranged at the end, the end portion detached from the heat insulating composite plate 1 arranged at the start end at the non-insulating material portion on the decorative gypsum board 2 generated by the slide of the heat insulating composite plate 1. Fit the portion 3c. By providing the end detaching portion 3c in this way, the above work can be performed without cutting the heat insulating material at the site.

Since the field edge 8 exists at the abutting portion of the heat insulating composite plate 1 arranged in the direction orthogonal to the extending direction of the field edge 8, the gap between the abutting portions of the heat insulating composite plate 1 arranged in such an arrangement is described above. It will be blocked by the field edge 8.

By the way, in the heat insulating composite plate 1, as shown in FIG. 5A, the slidable portion 3a may come off from the heat insulating composite plate 1 during transportation and construction. Therefore, the configuration shown in FIG. 5B may be adopted as the heat insulating composite plate 1. That is, all of the contact surfaces of the separation portion 3b and the slidable portion 3a are non-parallel (inclined) with respect to the thickness direction of the heat insulating material 3, and the contact surface of the separation portion 3b is on the decorative gypsum board 2. Diagonally opposed structures may be used.

Alternatively, the configuration shown in FIG. 5C may be adopted as the heat insulating composite plate 1. That is, a part of each contact surface between the separation portion 3b and the slidable portion 3a is non-parallel (orthogonal, etc.) to the thickness direction of the heat insulating material 3, and the non-parallel contact surface of the separation portion 3b. A structure may be used in which the portion of the surface faces the decorative stone board 2.

Further, in the above-mentioned indoor heat insulating method, an example of constructing a ceiling using a heat insulating composite plate 1 is shown, but the present invention is not limited to this, and an indoor wall can also be constructed using the heat insulating composite board 1. That is, when a plurality of heat insulating composite plates 1 as wall boards are arranged, for example, in the height direction (long side direction), no gap is generated at the abutting portion, and the above-mentioned makeup is performed at the stage before construction. It is possible to prevent the gypsum board 2 or the heat insulating material 3 from forming a single layer state. The same applies to the following other embodiments.

The separation portion 3b exists with a thickness less than the thickness of the heat insulating material 3. In the heat insulating material 3, a portion other than the separation portion 3b becomes a slideable portion 3a.

Next, an adhesive is applied to the separation portion 3b, and the decorative gypsum board 2 is superposed on the heat insulating material 3. With the adhesive, the decorative gypsum board 2 and the separation portion 3b are integrated, and a heat insulating composite plate 1A in which the separation portion 3b functions as a guide body 4 is produced. Further, the heat insulating composite plate 1A has an end detaching portion 3c that can be detached from the slidable portion 3a on one end side in the long side direction of the slidable portion 3a of the heat insulating material 3.

In the heat insulating composite plate 1A, the heat insulating material 3 has the decorative gypsum board 2 side as the upper bottom, and the upper bottom is smaller than the lower bottom. Each contact surface (a portion that becomes a trapezoidal leg) is inclined with respect to the thickness direction of the heat insulating material 3, and the contact surface of the separation portion 3b has a structure that diagonally faces the decorative gypsum board 2. If it is difficult to fit the concave portion of the end detaching portion 3c separated from the insulating composite plate 1 arranged at the start end into the separating portion 3b in the non-insulating material portion of the heat insulating composite plate 1A arranged at the end. , The end detaching portion 3c may be curved to widen the opening side of the concave portion.

Further, the guide member 4A is provided apart from each end of the decorative gypsum board 2 in the fixed direction. The heat insulating material 3 is supported by the guide member 4A on the edge side on the long side thereof and slides in the fixed direction (long side direction of the heat insulating material 3). Both the front and back surfaces of the heat insulating material 3 on the edge side in the long side direction are subjected to a shaving process corresponding to the wall thickness of the guide member 4A.

In the case of the heat insulating composite plate 1B, the entire heat insulating material 3 is a slideable portion. Further, since the heat insulating composite plate 1B has a guide member 4A having a U-shaped cross section, it is possible to reduce the possibility that the slidable portion 3a will come off from the heat insulating composite plate 1 when the heat insulating composite plate 1B is transported or constructed. In addition, in the heat insulating composite plate 1B, an end detaching portion may be provided on one end side of the heat insulating material 3 in which all of the above are slidable in a certain direction so as to be detachable from the heat insulating material 3. In this case, the guide member 4A may be separately provided so as to lock the end detaching portion.

In the case of the heat insulating composite plate 1C, the entire heat insulating material 3 is a slideable portion. Further, in the heat insulating composite plate 1C, since the other end of the substantially L-shaped guide member 4B is raised diagonally, the slidable portion 3a is heat-insulated when the heat insulating composite plate 1C is transported or constructed. It is possible to prevent the composite plate 1C from coming off. In addition, in the heat insulating composite plate 1C, an end detaching portion may be provided on one end side of the heat insulating material 3 in which all of the above are slidable in a certain direction so as to be detachable from the heat insulating material 3.
