Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a ridge of a downwardly sloping roof formed on a hipped roof, a square roof, or the like.

<Prior Art> As is well known, hipped roofs, square roofs, etc. have descending ridges that slope downward. When horizontally roofing such a roof with metal plates, the side edges of the left and right roof plates are butted against each other at the lower ridge, and a scrap board is placed on the lower surface of the butted portion, and a cover material is placed on the upper surface. Hat 1. (Problem to be solved by the invention) Therefore, in the past, the side edges of the left and right roof panels had to be cut and butted together at the construction site to match the slope of the ridge, which was extremely time-consuming. Construction requires skilled technology. In addition, the construction of the descending ridge must proceed on both the left and right roof surfaces at the same time, which tends to limit the construction procedure and is inefficient.Furthermore, there is a risk of rainwater infiltrating from the completed ridge. If the structure is not well-maintained, rainwater that has entered may corrode the main board and rafters.

Means for Solving the Problems> The present invention was proposed in view of the above, and has a first sloping board part and a second sloping part disposed on the left and right sides of the descending ridge, and both sill boards sides are disposed on the left and right sides of the descending ridge. They overlap at the top of the ridge, and a support part is provided on the upper surface of the overlap part, and the side ends of the roofing material are inserted into the support part from the left and right, and a cover material is attached.

<Function> Both the top parts of the left and right divided waste board parts can be overlapped and connected, and the side edges of the roofing material can be inserted into the support part provided on the top surface of the overlapping part, and the support part A descending ridge can be constructed by covering the roof with a cover material.

<Example> Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

On the left and right sides of the descending ridge l, a first waste board part 2 and a second waste board part 3 are arranged for each horizontal roof board. These waste board parts 2.
3 are triangular small members that are almost symmetrical to each other;
The waste board part 2 is a first top part 4 that bends in a mountain shape along the descending ridge.
The lower edge of the first top portion 4 facing the second cutout portion 3 is provided with a folded lower edge piece 5 above. An upward folding piece 6 is formed on the oblique side of the first waste plate part 2, and a downward hanging piece 7 is provided on the bottom side. Further, the second scrap board portion 3 has a second top portion 8 that bends in a mountain shape along the descending ridge, and a first portion of the second top portion 8
At the lower edge facing the waste plate part 2, an engaging part 9 having a diagonal cross section is formed in a bent manner. The engaging portion 9 has an insertion groove 10 that opens toward the second top portion 8 and an insertion groove 11 that opens outward. An upward folding piece 6 is formed on the oblique side of the second waste plate part 3, and a downward hanging piece 7 is provided on the bottom side. Incidentally, since the above-mentioned two-piece plate portions 2.3 are small members, they can be made by using an off-cut plate material.

The above-mentioned first sloping board part 2 and second stub board part 3 are connected appropriately at the descending ridge part, but in the embodiments shown in FIGS. An overlapping portion 12 is formed by overlapping such that the second top portion 8 of No. 3 is above the first top portion 4 of the first waste plate portion 2. A support portion 15 is provided on the upper surface of the overlapping portion 12 to which the side end portion 14 of the roof material 13 is inserted. In the embodiment of FIG.
The top of 2.

The side end portion 14 of the roofing material 13 is inserted into the support portion 15 and has an appropriate slope in accordance with the slope of the descending ridge 1. Further, as shown in FIG. 5, for example, the roofing material 13 is provided with a first locking part 17 by bending the upper edge upward and a second locking part 1B by bending the lower edge downward. Roofing material 1 adjacent to
3.13 can be connected.

A cover material 18 is attached to the upper surface of the support portion 15. The cover material 19 is a long material or a short material slightly longer than the depth of the roof material 13, and has inclined portions 20.20 on the left and right.
The lower end of the two inclined portions 20 is folded inward to form the adhered piece 21. Each adherend piece 21 is attached to the support portion 1
5 together with the side end fi14 of the roof material 13 to support the cover material 19.

The first waste plate part 2 as described above. Second scrap board part 3, support part 1
5. To construct the downhill building 1 using the cover material 18,
The first waste board part 2 and the second waste board part 3 are placed on the upper surface of the base material of the roof, and are appropriately fixed to the ridgepole with hangers, nails, screws, etc., if necessary. At this time, as shown in Fig. 1, it is preferable to set the 0-suke slope part 2.3 so that the lower part of the waste board fi2.3 placed in the upper row and the upper part of the waste board parts 2 and 3 placed in the lower part partially overlap. Once placed on the base material surface, the support plate 16 is fixed to the insertion groove 10 of the second scrap board portion 3 to form the right side portion of the support portion 15. Note that the support plate 16 may be fixed to the second waste plate part 3 in advance, and between the support plate 16 which is the right side part of the support part 15 and the upper surface of the second waste plate part 3, The side ends 14 of the left and right roofing materials 13 are inserted into the insertion groove 12 on the left side of the support portion 15, and the hanging portions 7 of each waste board portion 2.3 are inserted into the roof as shown in FIG. The roof is covered by fitting into the second locking part 18 of the material 13. In this case, it is possible to separately roof the left or right roof surface. After the left and right roof surfaces have been covered, a cover material 18 is applied to the upper surface of the support portion 15.

According to the descending ridge l as described in 1, the construction becomes extremely simple and the construction time can be shortened. In addition, since folded pieces 6 are formed on the left and right waste board parts 2 and 3, even if rainwater enters the lower surface of the roofing material 13, it can be transmitted through the folded pieces 6 and drained to the upper surface of the lower roofing material 13. , rain control has become extremely good,
The rafters and roof boards in the attic will not corrode.
