Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating envelope that has particularly excellent heat insulation performance, can reliably prevent the occurrence of dew condensation, and can be easily constructed.

BACKGROUND ART Conventionally, heat insulating enclosures such as various roofs or walls have been constructed using heat insulating building boards in which a heat insulating material is adhered to the lower surface of a folded metal building board. moreover,
In some cases, a heat insulating board is laid below the heat insulating building board, and a metal building board is further constructed on the underside of the heat insulating board. Although this type of configuration generally has superior thermal insulation performance, the roof system requires many repair components such as the eaves and gables, which requires careful attention to detail on site. Even if you are careful when constructing the roof, outside air will still infiltrate into the space between the metal building boards above and below, and air with a supersaturated humidity or higher will fill up there. When it is cooled by outside air, a lot of dew condensation occurs on the underside of the upper insulation material due to the cold bridging effect, and there are serious drawbacks such as condensation water collecting between the metal building boards above and below it. . When this happens, there is also the drawback that the heat insulation performance is reduced.

Therefore, as a result of extensive research aimed at preventing the occurrence of condensation, the applicant installed fiber-based or porous heat-insulating boards on structural materials such as the purlins or rims, and A heat-insulating folded building board with a heat insulating material provided on the lower surface of the metal folded building board via a support is successively installed so that the mountain part and the bottom part are continuous, and the bottom surface of the bottom part is By bringing the heat insulating material into close contact with the upper surface of the heat insulating plate, the heat insulating performance is particularly excellent, dew condensation can be reliably prevented, and the structure can be simplified and the above-mentioned drawbacks can be solved.

The structure will be explained with reference to the drawings.

Or, it is made of a porous system (foamed synthetic resin, etc.), and air is allowed to pass through the insulation material 2 slightly within a range that does not impair the insulation performance, or the air is avoided within the insulation board 2. , which is configured to circulate as if breathing, depending on the outside temperature and internal temperature. Such insulation board 2
is laid on the structural material 1. 3 is a support,
Its lower end is fixed to the structural member 1 and is provided so as to penetrate through the heat insulating material 2. Reference numeral 4 is a metal folded construction board, and there are multiple embodiments of the folded construction board 4, and in the first embodiment, the first
As shown in FIG. 7, etc., chevron portions 4b, 4b are formed on both sides of the bottom portion 4a. Further, as shown in FIG. 9, the height of the chevron portion 4b may be made relatively high to form a folded plate. In the second embodiment, as shown in FIGS. 4 and 10, bent-shaped portions 4c, 4c are formed on both sides of the bottom portion 4a, and the lower part 4d is above the outer end of the bent-shaped portions 4c, 4c. The ridge portion 4e is formed in a bent manner. In the third embodiment, F-shaped portions 4c, 4c are formed on both sides of the bottom portion 4a, and an inverted L-shaped portion 4f is bent from the outer end of the F-shaped portions 4c, 4c (Fig. 5, (See Figure 6). When the bottom portion 4a of each of the folded construction boards 4 is wide, one or more chevron-shaped bulges 4g are formed in a bent manner (see FIGS. 1, 2, and 9). The bottom part 4a of the folded construction board 4 (also on the lower surface of the chevron-shaped bulging part 4g if there is one) and the lower surface of the chevron part 4b or the F-shaped part 4c of the folded construction board 4. A heat insulating material 5 is attached along the cross section. The folded construction board 4 with the heat insulating material 5 is referred to as a heat insulating folded construction board A. The chevron-shaped portion 4a or the F-shaped portion 4c of the heat-insulating folded construction board A is placed on the upper part of the support 3, and the chevron-shaped portion 4a of the adjacent heat-insulating folded construction board A is placed on the upper part of the support 3.
(see Fig. 2), or the F-shaped part 4c of the adjacent heat-insulating folded building board A is butted and the lower part 4d and the upper part 4e are tightened through the hangers 6. (see FIG. 4), or the inverted L-shaped portions 4f, 4f are tightened via the hanger 6 and cap material 7 (see FIGS. 5 and 6). That is, the heat-insulating folded construction board A is roofed through the support 3 to form a mountain-shaped portion B consisting of the mountain-shaped portions 4b, 4b of the roof or wall.
and the bottom part 4a become continuous (first
(see Figure 2, etc.), or both F-shaped parts 4c, 4
The mountain-like part B and the bottom part 4a are formed so as to be continuous (see FIG. 4, etc.), and the heat insulating material 5 is provided so as to be continuous with the lower surface of the mountain-like part B and the bottom part 4a. . Further, the heat insulating material 5 on the lower surface of the bottom 4a of the heat insulating folded construction board A and the upper surface of the heat insulating board 2 are formed in close contact with each other. That is, the heat insulating folded construction board A is placed on the heat insulating board 2.

In the folded construction board 4 of the first embodiment, FIG.
As shown in FIG. 8, low-height protrusions (ribs) that are perpendicular to the longitudinal direction (or substantially perpendicular) may be continuously formed in a wavy shape on the bottom 4a. When the protrusions are formed continuously, they may be formed in a straight line in the longitudinal direction (see FIG. 7), or may be formed in a curved shape in the longitudinal direction when viewed from the side. In addition, there are multiple embodiments of the support 3, in which the base part 3b is formed at the lower end of the chevron-shaped part 3a (see Fig. 4), or it is formed in a substantially O-shape when viewed from the side (Fig. 3). A J-shaped portion may be integrated into the lower end of the O-shaped portion (see Fig. 14). or,
The whole may be formed into a rod shape (see FIGS. 1, 2, and 11 to 13). The main component of the rod-shaped support 3 is a metal support rod 3c with an internal thread formed at the lower end as shown in FIG. 11, or a synthetic resin support rod 3c as shown in FIGS. 12 and 13. The main component is the heat insulating rod 3d, and when it is installed, the upper and lower metal bolts are separated. In Figure 12, the insulation rod 3d

Further, the heat insulating board 2 may be coated with a moisture-proofing material such as a synthetic resin film or the like that allows proper ventilation or may be laid on the indoor side. In the figure, reference numeral 8 denotes a washer with a claw around the periphery, which is used to prevent the heat insulating material 2 from being dented by pressure when it is made of glass wool or the like. 9 is a short tube to prevent denting.

Next, the effects will be explained.

In the present invention, structural members 1 such as purlins or body lines
A heat insulating folded plate in which a fiber-based or porous heat-insulating plate 2 is laid on top, and a heat insulating material 5 is provided on the lower surface of a metal folded plate-shaped architectural board 4 via a support 3 on the structural material 1. The shape of the building board is successively laid so that the mountain-like part B and the bottom part 4a are continuous, and the heat insulating material 5 on the bottom surface of the bottom part 4a is brought into close contact with the top surface of the heat insulating board 2. It has particularly excellent insulation performance and can completely prevent the occurrence of condensation.Secondly, it is easy to configure, and thirdly,
It has many functions and effects, such as good strength, fourth, superior workability, and fifth, low cost construction.

To explain the effects in detail, even if a roof is constructed with the utmost care on site, there are many parts to be repaired as a system at the eaves, gables, etc., and the roof as a whole has a mountain-like shape. Outside air intrudes into the air space between part B and the heat insulating board 2, and even if the space is filled with air (air containing water vapor) with a supersaturated humidity or higher, the heat insulating folded plate By laying a fiber-based or porous heat-insulating board 2 below the shaped construction board A, the inside of the heat-insulating board 2 may be slightly ventilated within the range where the moisture-containing air does not impair the heat-insulating performance, or The air escapes into the insulation board 2,
This circulates as if breathing appropriately depending on the outside temperature and inside temperature, preventing a supersaturated humidity state, and even when the outside temperature cools down, the lower surface of the insulation material 5 of the insulation folded construction board A It is possible to reliably prevent dew condensation from forming on the roof or wall, eliminate the accumulation of condensed water on the heat insulating board 2, and provide a heat insulating enclosure with extremely excellent heat insulating performance. It can have revolutionary effects as a body system.

In addition, by successively laminating the heat insulating folded building boards A with the heat insulating material 5 provided on the lower surface of the metal folded building boards 4, the amount of heat loss through flow to the outside can be significantly reduced. As a result, the heat conduction resistance value can be increased, and when laminated with metal plates, a heat insulating envelope with extremely excellent heat insulation performance can be provided.

Furthermore, by making the heat insulating material 5 closely adhere to the upper surface of the heat insulating board 2, the heat insulating folded building board A is structurally supported by the structural material 1 through the heat insulating board 2. Therefore, it has the advantage of being strong against vertical loads such as snow accumulation. Further, since the structure does not require a metal construction board to be laid on the lower surface of the heat insulating board 2, construction can be performed easily and at low cost.
