Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a heat insulating support for connecting a lower roof and an upper roof in a roof having a heat insulating structure.

(Prior Art) Insulating roofs have been developed that have a double structure of roof plates with a heat insulating material inserted between them. The lower roof of a double roof is fixed directly to the main building, but the upper roof, which supports the insulation with the insulation in between, must also be connected to the main building. For this reason, the upper roof is connected to the main building via supports, but if these supports do not have an insulated structure, the supports will become a so-called heat bridge and transfer the heat from the upper roof to the main building. As a result, the outside temperature is induced into the inside of the building, which reduces the insulation effect by half.

Various types of supports for connecting the lower roof and the upper roof in an insulated roof have been introduced, and representative examples include Utility Model Application Publication No. 59-57618 (first precedent example) and Utility Model Application Publication No. 59-147816. Publication No. (2nd precedent)
There is.

Among the preceding examples, in the first precedent, the lower roof 11 is fixed to a receiving metal fitting 13 provided on the main building 12, and the supporting metal fitting A for attaching the upper roof 11 is attached to the receiving metal fitting through the lower roof with a drill screw. It is fixed at 13. The support fitting A is made of a steel plate.

The support fitting A of the first prior example has a structure that is attached to the receiving metal fitting 13 with a drill screw or the like, and once it is fixed, the position of the roof plate cannot be adjusted. Therefore, in order to adjust the position of the roof shingles, it is necessary to remove the support bracket A and reinstall it in a different position, but this requires accurate joining and assembly of the roof shingles (folded plates). This is a drawback because it is carried out on-site, but it is unavoidable under the current circumstances.

Further, the work of fixing the supporting metal fitting A to the roof or the roof and the receiving metal fitting 13 with a drill screw requires a great deal of labor since an electric drill is used. In particular, the receiving fitting 13 is thick in terms of strength, and it requires a great deal of effort to drill it with a drill screw. In addition, in the first prior example, the supporting metal fitting A is attached with a drill screw, but since the supporting metal fitting A is assembled by bolting two steel plates, there is a problem in its strength.

In addition, in the second prior example, the clamping fixture 1 is held at the joint of the lower roof, the two are bolted together, and the upper roof is attached to the clamping fixture 1, and the clamping fixture is made of synthetic material. Manufactured from resin.

In the second precedent example, the clamping device 1 is fixed to the lower roof with bolts, so if the roof plate is misaligned, the mounting position must be changed, as in the first example. It was hot.

(Problems to be Solved by the Invention) Conventional heat insulating supports have had problems in terms of ease of construction work, stability of strength, etc.
The present invention is an attempt to solve these problems of the prior art.The present invention connects the main body parts by using the flanges of the lower roof fixed to the main building, and connects the upper roof to the main building through a heat insulating material. It is intended to provide a thermally insulating support coupled to the body portion.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a support for connecting to the lower roof in an insulated double roof in which a cross section is interposed between the lower roof and the upper roof. The main body has a shelf plate and a side plate formed in a U-shape in cross section, and the side plate of the support main body is provided with a gutter-shaped stopper and a fixing bolt that advances and retreats toward the gutter-shaped groove of the support member.

There is no danger, and even if the heat insulating plates 12, 12 are destroyed by fire or the like, the connected state is maintained.

FIG. 4 shows a double roof constructed using the support of the present invention. The upper part of the bracket 20 installed on the roof structure material (not shown) is formed on a staircase, and the lower hanger 21 is attached to the step part 20a to connect the folded plate of the lower roof. It is fixed with bolts 23 via a plate 22. or,
The lower roof 24 has a folding plate 25 connected to the left side of the lower hanger 21 and a folding plate 26 connected to the right side of the lower hanger 21.
The lower seam part 27 is formed by overlapping with each other and tightening and fixing the three parts.

After the lower roof 24 is assembled, the support main body 1 is placed on the top of the lower roof, and the lower seam part 27 is assembled.
is brought into contact with the arc-shaped inner side of the stopper fitting 6, and the fixing bolt 9 of the mounting plate 7 is tightened to connect the lower flap part 27, that is, the support main body 1 and the lower roof 24,

In the insulating roof assembled in this way, the lower roof and the upper roof are connected via the insulating support, and the insulating support holds the synthetic resin that has a heat insulating effect, so the lower roof and the upper roof are connected. are connected so as not to form a so-called heat bridge.

(Effects of the Invention) The present invention places a support on the top of the lower roof, joins a stopper to the lower seam, and connects the support to the seam with a fixing bolt provided on the opposing part of the support. Since the support can be installed simply by tightening the bolts, the support can be installed without drilling holes in the roof, which has the effect of improving work efficiency at the assembly site.

In addition, in the present invention, the support main body is formed of an integral structure, and the part where the support main body is attached uses the part where the hanger and the left and right folding plates overlap and is most stable in terms of strength, so it is sufficient after installation. This provides strong strength.

Furthermore, the connecting members provided on the main body of the support are made of polymerized synthetic resin heat insulating plates, but since they are connected to each other with a metal material, even if the heat insulating plates melt due to a fire, the support will remain intact. Since the main body and the connecting member maintain a connected state, the support device also ensures safety.

In addition, in the connection member provided on the support body, a synthetic resin heat insulating plate was interposed between the connection plate that connects to the upper roof and the L-shaped plate fixed to the support body, so the problem occurred on the support body. It is possible to block the so-called heat bridge effect and fully demonstrate the effect as an insulating roof.
