DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A roof structure applied to a roof structure such as a shelter for walking or a shelter for walking will be described below in detail with reference to the accompanying drawings.

First Embodiment FIG. 1 is a detailed sectional view of a main part showing a first embodiment of a joint structure of a roof panel according to the present invention.

As shown in the drawing, aluminum panels 1 are arranged adjacent to each other while being supported by beams or columns (see FIGS. 8, 9 and 10). That is, the upper sealing material 3a and the lower sealing material 4
a.

The panel 1 includes a pair of surface plates 5 and 5,
The side frame 6 interposed between the four peripheral portions of the surface plates 5 and 5, and the core material 7 interposed in the space defined by the surface plate 5 and the side frame 6, are brazed or bonded to each other. It is formed integrally.

As the core material 7, for example, FIG.
As shown in FIG. 5A, a trapezoidal corrugated strip 7a having a so-called honeycomb structure in which the trapezoidal corrugated strip 7a is integrated by welding, brazing, or bonding, or an aluminum bent formed body or tube as shown in FIG. A honeycomb structure in which a large number of cylindrical bodies 7b are brazed or adhered is desirable. In particular, when a curved roof such as an arched shelter is formed, the cylindrical structure shown in FIG. The panel 1 is preferably formed using the core member 7 composed of the shape 7b. The reason is,
When the curved panel 1 is formed using the trapezoidal wavy band 7a, a process for bending the trapezoidal wavy band 7a, for example, a notch process such as a slit is required.
If b is used, such a notch process is not necessary, and a curved surface can be easily formed only by changing the height and shape (for example, a frustoconical shape) of the cylindrical body 7b.

When the panel 1 is formed by brazing,
For example, any one of the surface plates 5 and 5, the side frame 6 and the core material 7 is made of an aluminum clad material using a brazing material (JISA4045 or the like) on its surface, or the surface plate 1 and the core material 7 Without using any aluminum clad material for any of the frames 6, a brazing material is interposed between them and brazing is performed to melt the brazing material during heat treatment. The flux is a non-corrosive flux, for example, KF + A
1F3 or KAlF4 + K3AlF6 + K3AlF5.H
It is performed using a flux such as 2O, but when it is necessary to further increase the bonding strength, it is preferable to use the latter brazing material which has a deeper melting.

On the other hand, the upper sealing material 3a for sealing the joint 2 is composed of side frames 6, 6 of both panels 1, 1 facing the joint 2 and a projection projecting into the joint 2 from these side frames 6, 6. The joint 2 is formed by filling a solidified sealing material, for example, a caulking material, into the joint 2 partitioned in a U-shape by a backup material 9 supported by 8a and traversing the upper part of the joint 2.

As shown in FIGS. 1 and 2, the lower sealing member 4a has a flexible curved portion 4b which expands and contracts elastically.

Is engaged with the engaging portion 4c of the other seal member, and the lower sealing material 4a is interposed in the lower portion of the joint 2, so that the flexible curved portion 4
Due to the return force of b, the engaging portions 4c, 4c are brought into water-tight contact with the fitting grooves 10, 10, and a high sealing force is generated by this contact. Therefore, even if rainwater or the like intrudes due to stress cracks in the upper sealing material 3a, the rainwater is prevented from leaking downward. In this case, FIG.
As shown in the above, a ridge 8a projecting into the joint 2 is formed on the upper side of the side frame 6 by extrusion molding of aluminum.
When the fitting groove 10 is formed in the ridge 8a, the ridge 8a is formed.
a can also be used as the locking portion of the backup material 9, and the cost can be reduced accordingly.

When the upper seal member 3a is made of a sealable material that can be filled and solidified and the lower seal member 4a is formed to be elastically engaged with the side frame 6, the sealing work of the joint 2 becomes expensive. It can be easily performed with high quality, and can exhibit the original high seal of the double seal.

Second Embodiment In this embodiment, a pair of flexible sealing bodies are provided in which a lower sealing material is fitted into a narrow opening-like fitting groove provided in the side frame and is in close contact with each other. The shape of the fitting groove for elastically fitting the lower seal material is greatly different from that of the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and particularly, different components will be described in detail.
