Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a projecting corner joint structure for a folded plate roof that allows repair of projecting corner joints to be carried out simply and quickly, and also provides good rain protection.

[Conventional technology and its problems]

Traditionally, the construction of joint repair of folded plate roofs has been done by
When the folded plate roof was being constructed, the metal plates were processed to suit the needs of the projector to produce the lumber. However, it is not easy to process protruding corner laminated materials suitable for folded-plate roofs from metal plates on site; it requires skilled workers, requires a lot of construction time, and is expensive. There were some problems, such as: Furthermore, since the projecting corners are more often exposed to rainwater than other locations, there is also the problem that rainwater easily enters indoor spaces.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has developed the present invention, which consists of a metal folded plate roof and a protruding corner wall, in which a bottomed V-shaped part and a top part are alternately formed in succession. An L-shaped rising part is formed on the L-shaped edge on one widthwise side of the above-water side of the L-shaped main plate at the protruding corner part that contacts with, and a side door is formed at the middle of the below-water side end of the L-shaped main plate in the widthwise direction. The L-shaped rising part of the protruding corner joint material, which forms an outward downward sloping part from the other widthwise end of the L-shaped main plate, is placed along the protruding corner wall, and the side door is used as a folded plate roof. The projecting corner structure of a folded plate roof is inserted into the bottomed V-shaped part of the roof, and the inclined part is overlapped with the inclined surface of the adjacent bottomed V-shaped part, and the projecting corner joint material is attached to the folded plate roof. By doing so, it is possible to carry out the joint repair of the protruding corners easily and quickly, and also to achieve good rain protection, thus solving the above-mentioned problems.

Furthermore, the shape of the side door 9 differs depending on the embodiment of the folded plate roofing material _A1 . As shown in Fig. 2, if the folded plate roofing material _A1 is formed into an inverted trapezoid shape or has a lower part 3 and an upper part 4, the corresponding side door 9 may be used. As shown in FIGS. 5 and 7, the folded plate roofing material A ₁ of the third embodiment is formed with a downward convex shape, as shown in FIG. is formed so that it expands outward.

An inclined portion 10 is formed downwardly outward from the other end in the width direction of the L-shaped main plate 7 (the side opposite to the side on which the L-shaped edge 7a is formed).
A bent edge 10a may be formed inward from the lower end.

The L-shaped rising part 8 of the projecting corner joint material B is placed along the projecting corner wall 11 near the projecting corner point of the outer wall of the structure, and the projecting corner joint material B is placed on the folded plate roof A. , the side door 9 is inserted into the bottomed V-shaped part 1,
The inclined portion 10 is superimposed on the inclined surface 1a of the adjacent bottomed V-shaped portion 1, and the L-shaped main plate 7 is fixed to the folded plate roof A. At this time, the L-shaped main plate 7 of the projecting corner joint material B is fixed to the bracket 6 of the folded-plate roof A with bolts and nuts 6a, or fixed to the folded-plate roof material A ₁ itself with the fixing device 12. Sometimes it is done.

In the figure, 13 is a rubber cap that covers the fastening part of the folded plate roof A made of the folded plate roofing material _A1 of the second embodiment, 14 is a wall-joining drain material, and 15 is a side door. The wall-joining water-cutting material 15a is the door portion of the wall-joining water-cutting material 15 with a side door.

[Effect of idea]

In the present invention, the L-shaped main plate 7 is formed at the protruding corner portion where the metal folded plate roof A in which the bottomed V-shaped portions 1 and the top portions 2 are alternately and continuously formed is in contact with the protruding corner wall 11.
An L-shaped rising portion 8 is formed on the L-shaped edge 7a on one side in the width direction on the water side of the L-shaped main plate 7, and a side door 9 is provided in the widthwise middle of the water-side end of the L-shaped main plate 7. The L-shaped rising part 8 of the protruding corner lumber B, which has an inclined part 10 directed outward and downward from the other end in the width direction, is arranged along the protruding corner wall 11, and the side door 9 is attached to a folded plate roof. The protruding corner joint material B was attached to the folded plate roof A by inserting it into the bottomed V-shaped part 1 of A and overlapping the inclined part 10 with the slope 1a of the adjacent bottomed V-shaped part 1. By adopting a folded plate roof with a protruding corner structure, firstly, rain protection can be improved, and secondly, construction can be performed extremely simply and quickly.

To explain these effects in detail, by arranging the L-shaped rising portion 8 of the L-shaped main plate 7 along the protruding corner wall 11, the L-shaped rising portion 8
, and the L-shaped main plate 7 covers the folded plate roof A near the protruding corner, and since the L-shaped main plate 7 and the L-shaped rising portion 8 are substantially integral, they correspond to the protruding corner. This prevents rainwater from entering the room, and since the L-shaped rising portion 8 is provided on the water side of the L-shaped main plate 7, rainwater that hits the L-shaped rising portion 8 is It is also possible to prevent rainwater from flowing down to the water lower side of the main plate 7 and accumulating at the corner parts of the L-shaped main plate 7 and the L-shaped rising part 8, and the rainwater at the protruding corner parts can be kept very well.

Further, a side door 9 is provided at the lower end of the L-shaped main plate 7, and an inclined portion 10 is provided on the other side in the width direction of the L-shaped main plate 7.
is provided, and by inserting the side door 9 into the bottomed V-shaped portion 1, it is possible to substantially block the intrusion of rainwater that attempts to enter the bottomed V-shaped portion 1 near the protruding corner. , and there is a joint where adjacent folded plate roofing materials A ₁ and A ₁ are overlapped and connected near the protruding corner, with one end above the water in the longitudinal direction and the other at an intermediate position in the longitudinal direction. In this case, the top parts 2, 2 related to this joint location are covered with the L-shaped main plate 7, and the sloped surface 1a
Since the inclined portions 10 overlap, the joints of the adjacent folded-plate roofing materials A ₁ and A ₁ are wrapped in metal plates, and the joints of the folded-plate roof A are well protected from rain. There are also advantages to being able to do so.

Next, in the present invention, by simply arranging the L-shaped upright portion 8 of the L-shaped main plate 7 along the protruding corner wall 11, the side door 9 can be inserted into the bottomed V-shaped portion 1 at approximately the same time.
In addition, the inclined portion 10 can be superimposed on the inclined surface 1a of the adjacent bottomed V-shaped portion 1 of the bottomed V-shaped portion 1 into which the side door 9 has been inserted, which is extremely simple and easy. It can be constructed quickly. Therefore,
Compared to conventional de-sumi-ori-ai repair, which relies on the experience and skills of skilled workers to properly process metal plates on-site, advanced technology is not required and ordinary workers can However, construction can be done accurately and gracefully, and it can also be done simply and quickly, so construction costs and construction time can be significantly reduced, and construction efficiency can be greatly improved.
