Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for supporting a heat insulating material adhered to the back surface of a folded plate.

[0002]

2. Description of the Related Art Folded plates are used in many structures because they can cover a large roof area at low cost. Since the folded plate is formed of a metal plate such as a zinc iron plate, it is necessary to attach a heat insulating material or the like to the inside back surface of the folded plate in order to prevent dew condensation and reflection of sound generated in the room.

When attaching the heat insulating material or the like to the back surface of the folded plate, as shown in FIGS. 14 and 15, a method of adhering the heat insulating material 11 to the folded plate 4 with an adhesive, and as shown in FIG. There is a method in which a double folded plate structure is used and a heat insulating material 11 or the like is filled between the folded plates 4 and the like.

As a method of adhering a heat insulating material or the like with an adhesive, as shown in FIG. 15, when the heat insulating material 11 having a folded plate cross section is adhered after the folded plate 4 is constructed as shown in FIG. There is a case where the heat insulating material 11 is bonded to the folded plate 4 in advance and then the folded plate 4 is molded.

[0005]

[Problems to be Solved by the Invention] However, in the case of a metal roof such as a folded plate roof, the temperature of the roof surface is not constant and depends on the temperature of the outside air.
The temperature will be close to 0 ° C, and will be close to -20 ° C in the cold season of winter, and the annual temperature difference will exceed 100 ° C. This temperature difference hastened the deterioration of the adhesive agent and caused the heat insulating material 11 adhered to the folding plate 4 to peel off.

The heat insulating material 11 of the folding plate 4 is often made of glass wool which is inexpensive and has a heat insulating property as well as a sound absorbing effect. However, although glass wool is strong against heat, it easily absorbs water and moisture,
When a gap is formed between the folding plate 4 and the folding plate 4, dew condensation is likely to occur, and when dew condensation occurs on the folding plate 4, the condensed water is retained and the weight becomes heavy. For this reason,
As shown in FIG. 7, the glass wool heat insulating material 11 adhered to the back surface of the folded plate 4 is peeled off and hung down, or the heat insulating material 11 is not one sheet from the folded plate ridge to the eaves. Folded plate 4 is formed to a specified length
Since a plurality of heat insulating materials 11 are adhered to the back surface of the
In the worst case, the heat-insulating material 11 and the like in the portion which became heavy due to water retention dropped due to the weight.

Although the adhesive used for the folded plate is an adhesive that takes into consideration the temperature difference on the roof surface and expansion and contraction, it has a problem that it cannot maintain a stable adhesive force for a long period of time on all the bonded faces of the folded plate. And lacked credibility. Therefore, the adhesive partially deteriorates due to the temperature difference on the roof surface, and the heat insulating material or the like in the deteriorated portion peels off to form a gap. Condensation is likely to occur in the gaps, and the heat-insulating material or the like retains the condensed water and the weight becomes heavy. When the peeled portion spreads and the weight of the peeled and water-insulating material exceeds the adhesive strength of the adhesive,
As shown in 7, tight frame 10 and tight frame 1
Since the entire heat insulating material 11 between 0 and 0 is peeled off and hangs down, or in the worst case, the heat insulating material 11 in the portion which is heavy due to water retention falls due to its weight. is there.

Since many of the buildings using the folded plate 4 do not have a roof base material such as a ground plate or a ceiling, a heat insulating material 1
The peeling of No. 1 impaired the aesthetics from the inside of the room, and there was a serious problem such as being dangerous if dropped.

A double-folded plate in which the heat insulating material 11 is filled between the folded plates 4 does not cause the heat insulating material 11 to fall, but since the folded plate 4 requires twice the normal size. The cost was high.

The present invention is capable of supporting a heat insulating material or the like adhered to the back surface of the folded plate at a low cost for a long period of time, and peeling the heat insulating material or the like due to deterioration of the adhesive, or the heat insulating material or the like. An object of the present invention is to provide a support structure such as a folded plate heat insulating material that can solve the problems caused by absorbing water and absorbing moisture.

[0011]

Therefore, according to the present invention, a heat insulating material or the like adhered to the back surface of the folded plate is supported from the indoor side by a belt-shaped support member.

[0012]

When the heat insulating material or the like is peeled off, the whole is not peeled off from the beginning as described above, but the whole is peeled off after being partially peeled off. Therefore, even when the heat insulating material or the like is partially peeled off, if the heat insulating material or the like is supported by a member configured to be supported in the folding plate direction from the indoor side, the whole heat insulating material or the like is not peeled off. Absent.

For this reason, since the heat insulating material or the like adhered to the back surface of the folded plate can be supported from the indoor side by the belt-shaped supporting member, the heat insulating material or the like is caused by the partial deterioration of the adhesive or the like. Even if the heat insulating material or the like is partially peeled from the folded plate due to water absorption or moisture absorption, it is possible to prevent the peeling area from being expanded by the support member that can support the heat insulating material or the like from the indoor side in the folded plate direction. Therefore, the entire heat insulating material or the like will not be peeled off and hung down, or cut by weight and not dropped.

In this embodiment, a large number of holes are formed in each of the engaging portions 2 of the supporting member 1, and a string-shaped member is tied to the holes, and these string-shaped members are used as the supporting portion 3.

In this case, since the supporting portion 3 is composed of a string-shaped member, it does not cost much, and even if there is a portion where the thickness of the heat insulating material 8 adhered to the folding plate 4 is not constant. The support portion 3 can reliably support the heat insulating material 8. In this embodiment, since the engaging portion 2 and the supporting portion 3 are separate bodies, it is possible to attach the engaging portion 2 first and then attach the supporting portion 3 when attaching to the folding plate 4. . At this time, if there is a hooking tool that can be hooked in the hole at the tip of the string-shaped member, the support portion 3 can be attached more easily.

The material of the string-shaped member is a material having a low thermal conductivity, for example, a glass wool thread or the like having a low thermal conductivity, or the engaging portion 2 is a material having a low thermal conductivity. A strong material such as a piano wire may be used regardless of the ratio.

Next, another embodiment of the supporting structure for the folded plate heat insulating material and the like according to the present invention will be described.

It is possible. At this time, if there is a hooking tool that can be hooked in the hole at the tip of the string, the support portion 3 can be attached more easily.

The material of this string is a material having a low thermal conductivity,
For example, glass wool yarn or the like having a low thermal conductivity, or since the engaging portion 2 is made of a material having a low thermal conductivity, a strong material such as a piano wire may be used regardless of the thermal conductivity.

The material of the supporting portion 3 is a material having a low thermal conductivity, such as glass wool cloth or a hard rubber having a low thermal conductivity, or a material having a high strength regardless of the thermal conductivity.
For example, the same zinc iron plate as the folding plate 4 may be used. The thickness of the support portion 3 may be a plate thicker than the engagement portion 2.

In these embodiments, the supporting member 1 is made of a material having a low thermal conductivity, but when viewed from the inside of the room, the supporting member 1 is made of a material different from the heat insulating material 8, which may impair the appearance. Therefore, a net-shaped glass wool or the like may be further provided on the indoor side of the support member 1.

As described above, in the support structure of the folded plate heat insulating material and the like of the present invention, the heat insulating material 8 adhered to the back surface of the folded plate 4 is supported from the indoor side by the belt-shaped support member 1, so that the adhesion is achieved. Even if the heat insulating material 8 is partially peeled from the folded plate, the area of peeling does not spread due to the deterioration of the agent and the weight of the heat insulating material 8 which has retained water by absorbing and absorbing moisture. The entire material 8 is not peeled off and the heat insulating material 8 does not hang down or fall.

The cross-sectional shape of the engaging portion 2 of the supporting member 1 is the same as that of the overlapping portion 5, the fitting portion 6 or the fitting portion 7 of the folding plate 4, and the engaging portion 2 is folded. Since it is substantially sandwiched between the plates 4, it can be more firmly engaged. Therefore, even if the heat insulating material 8 adhered to the folding plate 4 becomes heavy due to water absorption and moisture absorption due to long-term use, it becomes a support material. 1 can securely support the heat insulating material 8 without falling off, and even if partial peeling occurs due to deterioration of the adhesive, the supporting portion 3 can prevent the peeled portion from spreading. .
