Description

TECHNICAL FIELD The present invention relates to a method for constructing a roof made of a metal plate.

(Conventional technology and problems) When constructing a roof, there is a corner ridge where roof surfaces intersect depending on the shape of the building such as a shrine or a tea room. Unlike the one-letter roof), it is called a corner ridge board, and a substantially L-shaped roofing board is used, and it has been conventionally called a turning roof.

The roof with this corner building is often seen in high-class buildings such as shrines and temples, and the appearance after construction is also important.

As a conventional method of constructing a corner ridge, the edge of another L-shaped corner ridge board main body and the edge of another roof board such as a one-lettered roof are raised and brought into contact with each other. A method has been adopted in which it is caught and bent to the lower surface side of the roof material and engaged and connected.

However, the connection work using such grasping chopsticks is a high-level technique among sheet metal technology and requires skill and experience, and it takes a lot of time and effort to install rain meticulously and have a good appearance. there were.

Also, when constructing single-letter thatch roofing materials, the end on the corner eaves side is cut off from the end of the single-letter thatch roofing material, and this single-letter thatch roofing material is also used as an adjusted roof plate and is used after being processed. It was

However, the vertical roof 2a and the adjustable roof 23
In order to match the seam of the vertical 23a with the one-row roof material of the lower tier, the roof of the comrades 2a, 2a There were insufficient steps, and there were narrow seams everywhere, and it was very unsightly in appearance. (FIG. 7) (Object of the invention) The present invention has been made to solve the above-mentioned problems, and does not use grasping chopsticks or the like as in the conventional case when constructing a corner ridge of a roof. The construction can be done simply by sequentially engaging the upper and lower engaging pieces of the corner ridge board with each other, the work does not require skill or experience, and the corner ridge board A used for the corner ridge part of the roof of the one-letter roof The adjustment roof plate 23 connected with the length is longer than the lateral length of the one-letter roofing material 2, and the length of the last two-letter roofing material from the seam 2a to the corner ridge is not enough. You can

Therefore, by using the adjusting roof plate 23 longer than the one-character roofing material 2, the side bending pieces 13 of the corner ridge board A and the one-character roofing material 2 are fitted.
The space between the seams 23a and 2a between the 2a and the one-letter roofing material 2 is not narrowed, and the appearance of the seams is adjusted and the neat finish is completed to provide a good method of constructing the corner ridge. It is a thing.

(Structure of the Invention) Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings.

1 shows a perspective view of the corner ridge board A, and FIG. 2 shows a perspective view of the corner ridge board A in FIG. 1 when viewed from the lower surface side.

A corner ridge board A formed by bending a thin metal plate such as a copper plate has a main body 1 formed in a substantially L shape, and a wing that abuts a corner ridge of a roof in the vertical direction at the center of the main body portion 1. It is bent to the lower surface side at the top portion 14.

The bending angle of this ridge top 14 should be designed according to the angle of the corner ridge to be constructed, and the angle should be large when the roof slope is large and small when the roof slope is small. The substantially L-shaped inner corner angle and outer corner angle of the main body 1 are also designed arbitrarily according to the angle of the corner ridge.

Further, the upper edge forming the inner corner which is the water side of the main body 1 is provided with an upper engaging piece 11 which is bent toward the upper surface with a gap, and the lower edge which forms the outer corner which is the water side. Is a lower engaging piece 12 which is also bent at the lower surface side with a gap therebetween, as shown in FIG. 3 (b).
It is provided as shown in.

Further, as shown in the perspective view of FIG. 2 and FIG. 3 (a), both side edges of the main body portion 1 are folded back to the lower surface side to form side bent pieces 13, and the side edge is wavy. Prevents deformation.

The side bending piece 13 is folded back by 180 ° in the illustrated example, but the purpose can be achieved even when the bending angle is about 90 ° to 150 °.

23 is an adjusting plate. The adjusting roof plate 23 has the same shape as the one-character roofing material 2 described later, and has a long lateral length, which is at least about 1.6 times the length of the one-character roofing material 2.

In the case of one-letter thatch, the roof 2a is moved to the half position of the one-letter roofing material 2 while shifting the position of the roof 2a for each step of the roof. , When the roof is covered with only the one-letter roofing material 2, a step where the last seam of the last one-letter roofing material 2 is located inside the side bent piece 13 of the upper corner ridge board A is formed. Since it is possible to make a narrow seam, make it at least one and a half times that of the roof material 2.
It is about 1.6 times, considering other margins.

When a narrow seam is formed as described above, the adjusting roof plate 23 described above is processed and used as described later.

The corner ridge board A constructed as described above is constructed on the corner ridge portion of the roof as shown in FIG. 4, and the one-piece roofing material 2 is constructed on the roof surface in advance.

This one-character roofing material 2 is constructed by bending engaging pieces around the periphery of a substantially rectangular main body.

Then, the one-letter roofing material 2 that is roofing from the center of the roof surface toward the corner ridge is cut diagonally along the corner ridge at the portion reaching the corner ridge (on-site work). An upright portion 21 bent upward is formed at the edge (Fig. 5).

At this time, the adjustment roof plate 23 is arranged so that the joint between the final one-letter roofing materials 2 and 2 is not located inside (side of the corner ridge) the side bending piece 13 of the corner ridge plate A one step higher. Excuse me.

That is, when the length is sufficient, the one-character roofing material 2 is processed and used as described above, and when the length is insufficient, the above-mentioned long adjustable roof plate 23 is used to join the seams near the corner ridge. Reduce the number and align the vertical to make the appearance even. (Fig. 6) In this way, the corner ridge board A is sequentially installed from the lower part to the upper part in the corner ridge part of the roof where the single-character roofing material 2 and the adjustment roof plate 23 are installed. Upper engaging piece 11 of ridge board A
Then, the lower engaging piece 12 of the corner ridge board A located on the upper side is engaged and the roof is raised upward.

That is, the lower engaging pieces 12 are inserted into the gaps of the upper engaging pieces 14 bent with a gap therebetween to engage and connect, but at this time, the upper engaging pieces 11 of the corner ridge board A are the adjusting roof boards. The corner ridge board A is constructed by inserting a gap in the upper side of the upper engaging piece 22 which is folded back to the upper surface side with a gap provided in the upper side of 23.

By inserting the upper end of the corner ridge board A into the gap between the upper engaging pieces 22 in this manner, the side ends of the corner ridge board A closely contact the upper surface of the roofing material 2 without any gap, and the appearance is good and rainwater is prevented from entering. It can be prevented.

Further, the rain from the side end of the corner ridge board A can be completely prevented by the standing portion 21 provided at the end of the roof material 2 on the corner ridge side.

(Effects of the Invention) As described above, in the method for constructing the corner ridge board according to the present invention, the engaging pieces bent with a gap between the upper and lower sides of the substantially L-shaped body are sequentially engaged from the lower side to the upper side. It can be installed by itself, and since it does not use grasping chopsticks as in the past, it can be installed easily without requiring any experience.

Further, since a long adjustable roof plate is installed near the corner ridge, the seams on the roof surface are reduced and the appearance is improved.
