Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention can prevent rainwater from entering and can be installed easily and quickly. Especially, in the cold weather, the roof surface or joint is safe against icing. To improve and prevent spillage, and the roof and ceiling part has a substantially integrated structure,
This relates to a roof that can further improve workability.

[0002]

2. Description of the Related Art In recent years, many roofs made of metal have been used, and among them, many flat roofs exist.
In the case of the roof, the flat portion of the roof material constituting the roof is formed in a large area. In general, the roof is constructed by fixing the gutter on the structural material, fitting the end part of the roof material to the gutter, and fixing the cap material between the adjacent roof materials. To do.

[0003]

By the way, such a roof having a flat surface has an aesthetic and original appearance. However, because of the flat shape, rainwater easily flows to any part of the surface of the roof, and rainwater may infiltrate through the joints between the roofing materials, which may lead to rain leakage into the room.

Therefore, there is a type in which rainwater can be discharged to the outside by providing a gutter at the joint between roofing materials. Furthermore, the joint part between the roof materials is
By providing a watertight finish, it is possible to prevent rainwater from entering the gutter, and there are some that have further improved waterproofness.

In such a roof, the roof material is fixed by a gutter, and the gutter is fixed to a beam material such as a purlin, so that the construction site of the roof and the construction site of the ceiling are It will be done in different setups. However, such metal roofs are often used mainly in large-scale buildings, and therefore construction period of such buildings is limited. In particular, the construction of the roof has a great influence on the construction of other parts, and the construction period may be extended. For this reason, a structure that allows the roof and ceiling to be constructed integrally is desired.

[0006]

Therefore, as a result of intensive studies, the inventors of the present invention have solved the present invention as a result of solving the above problems.
A gutter in which a pair of fitted parts facing inward from both widthwise sides of the upper part of the gutter body are formed, and supporting projections are formed from both sides in the widthwise direction at the bottom portion, and the gutter from both sides in the widthwise direction of the ceiling main plate. The ceiling material is formed with locking rising sides having locking bent pieces that lock to the fitting portion, and the fitting side portions that are fitted to the fitted portion of the gutter are formed on both sides in the width direction of the roof main plate. , A roofing material in which a connecting rising portion is formed outward from the lower ends of both fitting side portions, and the ceiling material is arranged between the adjacent gutters installed at predetermined intervals, and the ceiling material is The locking bent pieces are locked to the fitted parts of the gutter, the roof material is arranged from above the ceiling material, and the roof bending material is locked to the fitted parts. The mating side parts of the mating parts are mated, and the opposing connecting rising parts of the adjacent roofing materials are connected to each other. By using a roof or the like in which both end portions of the ceiling material are supported by both protruding ridges of the gutter, the construction efficiency is improved, and the mechanical strength and durability are excellent, and rainwater The problem described above is solved by significantly improving the performance of preventing the infiltration of the.

[0026]

According to the invention of claim 1, a pair of fitted parts 1 facing inward from both sides in the width direction of the upper part of the gutter body 10.
1, 11 and the gutter C in which the protruding protrusions 10a, 10a for supporting are formed on both sides in the width direction at the bottom portion, and the locking for locking the fitted portions 11, 11 from both sides in the width direction of the ceiling main plate 6. The ceiling material B having the locking rising side portions 7 and 7 having the bent pieces 7b and 7b, and the fitting side portions fitted to the fitted portions 11 and 11 of the gutter C on both sides in the width direction of the roof main plate 1. 2 and 2 and a roofing material A in which the connecting rising portions 3 and 3 are formed on the outer side from the lower ends of both fitting side portions 2 and 2, and the gutters are installed at predetermined intervals and are adjacent to each other. C,
The ceiling material B is arranged between C, and the B locking bent pieces 7b, 7b of the ceiling material are fitted portions 11, 11 of the gutter C.
The roofing material A is arranged above the ceiling material B, and the fitting side of the roofing material A with respect to the locking bending pieces 7b, 7b locked by the fitting parts 11, 11. The parts 2, 2 are fitted to each other, and the opposing connecting rising parts 3, 3 of the adjacent roofing members A, A are connected to each other, and the ceiling member B is connected by the both supporting protrusions 10a, 10a of the gutter C. Since the roof is formed by supporting both end portions of the above, firstly, the workability can be made extremely excellent, and secondly, the roof can be made extremely excellent in waterproofness. Has various effects.

To describe the above effect in detail, the ceiling material B is formed with both locking rising side portions 7, 7 having the locking bent pieces 7b, 7b, and the roof material A is fitted with the fitting side portions 2, 7. 2 are formed, and both of the locking bending pieces 7b, 7b and the fitting side portions 2, 2 are formed.
Are both engaged or fitted with the fitted parts 11, 11 of the gutter C. Therefore, the ceiling material B is first fixed to the fitted parts 11 and 11 of the adjacent gutters C and C via the both locking bent pieces 7b and 7b, and then the fitted parts 11 and 11 are fixed to the fitted parts 11 and 11. By fitting the fitting side portions 2 and 2 of the roof material A from above the locked and bent locking pieces 7b and 7b,
The roof material A and the ceiling material B can be installed substantially simultaneously, and the working efficiency can be improved.

Further, the roofing material A has fitting side portions 2 and 2 formed on both sides in the width direction, and connecting rising portions 3 and 3 are formed outward from the lower ends of the fitting side portions 2 and 2. It is a thing. further,
