2. Description of the Related Art Generally, a conventional heat insulating roof structure is one in which a base material such as a composite panel and a heat insulating material are individually attached. However, it takes a lot of time and trouble to attach the heat insulating material to the main body. There is a problem that it is necessary to insert materials and the like in detail.

On the other hand, as shown in FIG. 4, as the heat insulating roof panels 21A and 21B, the upper and lower metal plates 22a and 2a are formed.
There is known a structure in which a heat insulating material 23 is sandwiched between 2b to reduce the number of purlin materials and the base material is unnecessary (JP-A-2-147742, JP-A-2-147743). See the bulletin).

Such heat insulating roof panels 21A, 21B
Regarding the joints between them, there is a problem of maintaining rain and heat insulation. As a conventional joint structure, as shown in the same figure, the ends of the heat insulating roof panels 21A and 21B are fitted to each other. Insulated roof panel 21B with a matching shape
Is fixed to the support member 20 with a fixture 24 such as a self-drilling screw, and is abutted against the other insulating roof panel 21A with a packing 25 or the like interposed therebetween, and the cap 26 is engaged with the abutted upper portion, Some are coated.

[0005]

The structure of FIG. 4 has the following structure.
Since the heat-insulating roof panels are joined by concave and convex fitting, the accuracy is strict, the joinability and workability are poor, and the heat-insulating roof panel itself is difficult to mold. There is a problem that you cannot get a face.

The present invention has been made in order to solve the problems in the prior art as described above, and its object is to provide a flat roof having excellent workability, watertightness and airtightness. An object is to provide an insulating roof structure capable of forming a surface.

[0007]

According to a first aspect of the present invention, there is provided a heat insulating roof structure in which a heat insulating roof panel formed by sandwiching a heat insulating material between upper and lower metal plates has a flat upper surface. A gutter member that connects the upper portions of the heat-insulating roof panels to form a recess and a joint cover that covers the upper surface of the gutter member are installed so that a flat roof surface is continuous.

The watertightness of the roof structure is ensured by the gutter member installed at the joint portion, and a part of the rainwater that has entered the gutter member from the roof surface is drained through the gutter member. Also,
By interposing the gutter member, it is not necessary to make the end shape of the heat insulating roof panel into a complicated shape, and dimensional accuracy and construction accuracy can be relaxed, which is also advantageous in terms of workability.

In the heat insulating roof structure according to the second aspect of the present invention, a downward projecting ridge is formed at the connecting end portion of the heat insulating roof panel, and the connecting end portions of the heat insulating roof panels stacked below the gutter member are screwed. The case where it is fixed to the upper surface of a support member such as a beam member by a fixture such as a self-drilling screw is limited.

In this case, a high joint strength can be obtained through the fixture, and the gutter member and the joint cover have a function of blinding the fixture and ensuring continuity of the flat roof surface.

In the heat-insulating roof structure according to claim 3, the heat-insulating roof panel has flat upper and lower surfaces, and a concave portion into which the gutter member is fitted is formed on the upper surface side of the connecting end portions of the heat-insulating roof panels. Is limited.

In this case, the heat insulating roof panel has a simple shape, and the heat insulating roof panel itself does not require special processing, which is advantageous in terms of economy and workability.
