[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a heat-insulating double roof having a lower roof composed of a folded plate, a heat insulating material layer and an upper roof provided above the heat insulating double roof, and the heat insulating double roof. The present invention relates to an upper roof mounting device used for a heavy roof.

[Conventional technology]

FIG. 6 shows a conventional example. In the figure, 1 is a lower roof made of a denim plate, 4 is a heat insulating material layer made of glass wool, and 3 is an upper roof made of a denim plate. Reference numeral 5 denotes a panel receiving frame fixed to the upper surface of a purlin or a beam, and 6 denotes a lower roof hanging member attached to the panel receiving frame 5 with bolts and nuts 7. It is fastened and fixed. Reference numeral 27 denotes a metal frame for attaching the upper roof, which is horizontally bent from the horizontal plate portion a and the inclined plate portions b and b rising obliquely from both ends thereof and the upper end thereof, and then bent upward and horizontally at the upper end portion. It is composed of a pair of sandwiching plate parts c, c having different folding parts. Between the sandwiching plate portions c, c of the left and right frames 27, 27, a pair of synthetic resin heat insulating thin plates 28, 28 having a cross-sectional shape corresponding to the sandwiching plate portions c, c, and the heat insulating thin plate 28, An upper roof metal hanger 13 located between the two is interposed, and these are integrally connected by bolts and nuts 14 ... Then, after laying the heat insulating material layer 4 on the lower roof 1, the roof portion of the upper roof 3 is fastened and fixed to the metal suspension 13, and the upper roof 3 and the frames 27, 27, 27, 27, 27 and lower roof 1
I try not to touch each other.

[Problems to be solved by the device]

 The above-mentioned conventional example has the following problems.

Since the frames 27, 27 adjacent to each other are large members compared to the hanger 13 and the like, the frames 27, 27 and a pair of synthetic resin disposed between the clamping plates c of the frames 27, 27 are made of synthetic resin. If the upper roof mounting device consisting of the heat insulating thin plates 28, 28 and the metal suspension 13 is temporarily assembled in advance, it becomes a long member, which is cumbersome to store and transport and is heavy, and the lower roof 1 The work of attaching to the position of the fridge, that is, the workability was very bad.

The work of inserting the heat insulating material into the gap formed between the horizontal plate portion a or the inclined plate portions b and b of each frame 27 and the lower roof 1 was troublesome. Further, if the heat insulating material is not inserted and is left in the gap, the heat insulating material layer 4 is thin at the position of the gap and the heat insulating performance is locally reduced, so that dew condensation occurs on the surface of the lower roof 1. There was an occasion.

It is necessary to make a panel receiving frame for mounting the upper roof depending on the working width of the roof material, which not only takes time to manufacture the frame, but also member management is troublesome.

An object of the present invention is to eliminate the above-mentioned problems of the conventional example.

[Means for Solving the Problems] The technical means taken by the present invention to achieve the above object are as follows. That is, the heat-insulating double roof according to the present invention has a vertical hole for inserting a suspender formed at a substantially central portion of the upper surface,
A vertical block with a horizontal piece and a plurality of bolt insertion holes formed on the left and right sides of a synthetic resin block that has a plurality of horizontal holes for inserting bolts. A pair of metal sandwiching pieces each having a piece portion are positioned such that an upper end of the metal sandwiching piece is located below an upper surface of the synthetic resin block through a bolt inserted across the lateral hole and the bolt insertion hole. Mounted in a state, on the upper surface of the synthetic resin block, a metal suspension, a bolt insertion hole formed in the hanging plate portion of the suspension inserted into the vertical hole and a bolt insertion hole of the vertical piece portion A state in which the upper roof mounting device, which is mounted via bolts inserted over the lateral holes, is clamped on the roof fastening portion of the lower roof by the lateral piece portion of the metal sandwiching piece from both sides of the leg portion of the snack fastening portion. Attached to the lower room Upward provided a heat insulating material layer, it is characterized in that the upper roof provided above the heat insulating material layer is fixed to said metallic retaining clips.

In addition, the upper roof mounting device according to the present invention has a vertical hole for inserting a suspender formed substantially at the center of the upper surface, and a horizontal hole for inserting a plurality of bolts formed on both left and right side surfaces of a synthetic resin block on both left and right sides. On the surface, insert a pair of metal sandwiching pieces each having a horizontal piece portion and a vertical piece portion that is bent upward from one end thereof and has a plurality of bolt insertion holes formed therein, extending across the horizontal hole and the bolt insertion hole. It is attached in a state in which the upper end of the metal sandwiching piece is located below the upper surface of the synthetic resin block via the bolts, and a metal suspension is provided on the upper surface of the synthetic resin block with the vertical hole. The bolt is inserted through the bolt insertion hole formed in the hanging plate portion of the suspension inserted in the above, the bolt insertion hole of the vertical piece portion, and the horizontal hole.

[Action]

According to the above configuration, a large number of components such as a synthetic resin block, a pair of metal sandwiching pieces, and metal hangers are integrally assembled to form an upper roof mounting device, which is used for the lower roof. Since it is attached to the fastener part, it is easy to install the device to the fastener part of the lower roof,
Moreover, the upper roof mounting device is independent for each fastening portion of the lower roof, and since there is no conventional frame between the adjacent fastening portions, there is no gap between the frame and the lower roof. Since the work of inserting the heat insulating material is omitted, the workability as a whole is good.

In addition, there is no local decrease in heat insulation performance due to the gap between the frame and the lower roof as in the conventional case.
