DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an insulated roof, and more particularly, to a support member mounted on a structural material such as a beam or a purlin, and a joiner is erected and supported between the structural materials and between the support members. More specifically, the present invention relates to a structure of an insulated roof in which a heat insulating material extends between structural materials and is laid on a ceiling supported by a joiner, and a metal folded plate roof material is supported and laid by a support bracket. By effectively using the support metal fittings to support the insulation material, the floating of the heat insulating material is effectively prevented, and the positioning of the joiner that supports the heat insulating material laid on the ceiling is facilitated to enhance the workability, and The present invention relates to a technique for maintaining the function of a heat insulating material satisfactorily for a long period of time and making it advantageous in a heat insulating roof.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 10, a heat insulating material 3 is supported and laid on a joiner 6 extending between structural materials 1 such as beams and a purlin, and a heat insulating layer 5 is lined on the back surface. In the structure of the insulated roof in which the folded sheet roofing material 4 is supported by the supporting metal fittings 2a and is laid, the heat insulating material 3 and the heat insulating layer 5 lined with the roofing sheet material 4 form the heat insulating space E, so that sufficient heat insulation is achieved. Properties, especially the backing insulation layer 5
Thus, dew condensation can be prevented, problems due to dew condensation can be avoided, and the roof can sufficiently function as an insulated roof.

[0003]

By the way, although the heat insulating space E is formed between the heat insulating material 3 and the folded plate roof material 4, the heat insulating material 3 easily floats by the wind, and the heat insulating material constituting the ceiling is formed. Lumber 3
Was easy to come off. To solve such a problem, a groove 6b is formed in a joiner 6a as shown in Japanese Utility Model Laid-Open Publication No. 5-84722 shown in FIG.
There has been proposed a device in which the heat insulating material 3 is inserted into the heat sink to prevent the heat insulating material 3 from floating.

However, in such a configuration, the joiner 6a is fitted and supported by a fitting 6c inserted and supported in the hole 2b of the support fitting 2a. There is almost no function to prevent ascent,
As a result, there is a problem that the heat insulating material 3 floats together with the joiner 6a. Further, since the joiner 6a is inserted into the attachment 6c having a similar shape,
Positioning in the longitudinal direction of the joiner 6a cannot be performed.
It takes time and effort to insert the joiner 6a into the fixture 6c, and the workability is reduced. In particular, when the heat insulator 3 is lifted and inserted into the groove 6b of the fixture 6c, the depth of the groove 6c is limited by the heat insulator. 3 is substantially equal to the thickness of the heat insulating material 3, and there is a problem that the work of fitting the heat insulating material 3 into the groove 6c requires time and effort.

[0005] Further, moisture adheres to the lower surface of the heat insulating material 3 serving as a ceiling material due to dew condensation or the like, which penetrates into the heat insulating material 3 to accelerate deterioration of the heat insulating function, and further binds the heat insulating material. The binder function is deteriorated due to the aging of the binder, etc., and the fine heat insulating material falls as dust, and the heat insulating material 3 itself, which surrounds and holds the air for heat insulation, has poor sound insulation and sound insulation functions. Further, there is a problem that it is difficult to enhance the appearance as a ceiling material.

The present invention has been made in view of such a problem, and an object of the present invention is to make effective use of a supporting bracket for supporting a folded-plate roof material to effectively float a heat insulating material. It facilitates the positioning of the joiner that blocks and supports the heat insulating material laid on the ceiling, improving the workability, and facilitating the work of inserting the heat insulating material into the joiner from below. In particular, it can prevent moisture from penetrating into the heat insulating material, maintain the heat insulating function for a long period of time, and even if the binder deteriorates due to aging, the heat insulating material becomes garbage and falls. It is possible to avoid the damage of the lower surface of the end of the heat insulating material when holding and preventing the floating of the heat insulating material, and to prevent the floating of the heat insulating material. Yes in the configuration to hold In the attempt to provide a structure of a heat-insulating roof.

To prevent the floating of the joiner 6, and as a result, the insulating material 3 supported between the joiners 6 and 6 can be prevented from floating by the wind. 3 prevents moisture from penetrating into the heat insulating material 3 by the moisture-proof layer 3a on the lower surface of the heat insulating material 3, thereby maintaining the heat insulating function for a long period of time. It can prevent falling as garbage, enhance sound insulation and soundproofing function, and also enhance the appearance, and also damage the lower surface of the end of the heat insulating material when holding and stopping the floating of the heat insulating material This is advantageous in a configuration in which the floating of the heat insulating material is prevented and held.
