A vertical edge portion 1b is formed on the other edge. The above-mentioned inclined edge portion 1a is inclined at about 45 degrees with respect to the length direction of the connecting roof panel 1, and the vertical edge portion 1b is perpendicular to the length direction of the connecting roof panel 1. Therefore, the upper edge along the longitudinal direction of the connecting roof panel 1 is shorter than the lower edge along the longitudinal direction. And the connecting roof plate 1
A fitting portion 2 is formed on the inclined edge portion 1a of the slanted end portion 1a.
Note that the left and right connecting roof panels 1, 1 are symmetrical.

The fitting part 2 is a connecting roof plate 1 made of a flat plate material.
an upright piece 3 with an inclined end portion 1a raised upward;
It consists of a fitting piece 4 with the tip of the upright piece 3 bent downward in a folded shape. A substantially right-angled notch 2' is formed at the rear end of this fitting part 2.

An upward locking portion 5 is provided on the rear edge of the connecting roof panel 1, and a downward engaging portion 6 is provided on the front edge of the connecting roof panel 1.

The locking portion 5 is composed of a locking piece 7 which is formed by bending the rear edge of the connecting roof plate 1 upward in a curved shape, and a bent piece 8 which is formed by folding the tip of the locking piece 7 back.

Further, the engaging portion 6 is composed of a bent piece 9 which is formed by bending the front edge of the connecting roof plate 1 downward, and an engaging piece 10 which is formed by bending the tip of the bent piece 9 backward.

In addition, a sealing material 11 is applied at the interval where the fitting parts 2, 2 of the connecting roof panels 1, 1 butt against each other at the descending ridge part a.
intervene. This sealing material 11 is in the shape of a thin, flat, rectangular plate, and it is preferable to interpose the sealing material 11 because rain protection can be ensured.

Adhesive device 1 to be applied to the butt part as above
2 has approximately the same length as the inclined edge portion 1a of the connecting roof panel 1, and is formed by, for example, bending a metal plate into an inverted V shape so that the lower surface is open. Then, on the left and right lower edges of the adherend 12, adherend pieces 13, 13 which are folded upward inwardly are formed in a bent manner. Further, diagonal notches 13', 1 are provided at both ends of the adhered pieces 13, 13.
3' is formed. This adherent 12 may have an inclined shape with one end being high and the other end being low, or may have the same height over its entire length.

In order to construct the descending ridge part a, which is the connecting part of the roof, using the above-mentioned connecting roof board 1, sealing material 11, and fitting 12, the left and right connections must be made at the eaves at the lower end of the descending ridge part a. The roof panels 1, 1 are placed, and the engaging portions 6, 6 on the front edges of the connecting roof panels 1, 1 are engaged with the roof panel support portions of the eaves fittings (not shown), and the connecting roof panels 1 are , 1 between the fitting parts 2, 2.
The fitting parts 2 and 2 are butted against each other with the fitting part 1 interposed therebetween. Since the descending ridge part a is mountain-shaped with a low height,
When the upright pieces 3 of the fitting part 2 are erected at an angle slightly larger than 90 degrees with respect to the connecting roof board 1, when the left and right fitting parts 2, 2 are butted against each other, both the upright pieces 3,
3 face each other in parallel.

Then, the fitted parts 2 and 2 are fitted with a fitting tool 1.
2 (Figures 2 and 3).

FIG. 2 shows one higher end 12a of the adherend 12.
This figure shows the case where the attachment tool 12 is attached to the fitting parts 2, 2 so that the lower end of the lower end is located above the inclination of the descending ridge part a, and the other end is located above the inclination of the descending ridge part a.
Apply the lower end of the connecting roof panels 1, 1 to the front edge of the abutting part, and attach each adherend piece 13 to each fitting part 2, 2.
By fitting the fitting piece 4 into the fitting piece 4 and pushing the fitting 12 in the length direction, the fitting 12 can be fitted to the abutting portion of the fitting parts 2, 2 of the connecting roof panels 1, 1. In this state, as shown in FIG. 5, the adhered piece 13 faces the lower end of the fitted piece 4.

In the case of FIG. 2, since one end 12a of the adherent 12 has a high opening, the sealing material c is filled in the opening to prevent rainwater from entering.

On the other hand, the embodiment shown in FIG. 3 shows a case where the higher end of the attachment device 12 is attached to the fitting portions 2, 2 so as to be located above the slope of the descending ridge portion a.
Apply one high end of the adherend 12 to the front edge of the abutted portion of the connecting roofs 1, 1, and attach each adherend piece 13, 1.
3 into the fitting pieces 4, 4 of each fitting part 2, 2 and pushing the adherend 12 in the length direction, the butt part of the fitting parts 2, 2 of the connecting roofs 1, 1. The attachment tool 12 can be attached.

As shown in Fig. 3 above, the attached fittings 12 have the same height, and since only the lower end of the slope has an opening, this opening is filled with a sealing material c to prevent rainwater from entering. However, the connecting portion of each adherend 12 may be filled with a sealing material c.

Note that when attaching devices 12 having the same overall length are attached to the butt portions of the fitting portions 2, 2 of the connecting roof panels 1, 1, a small opening is formed in the connecting portion of the vertically adjacent attaching devices 12. Since a portion is generated, it is sufficient to fill this portion with a sealing material.

After the left and right connecting roof panels 1, 1 are butted together and the fitting 12 is fitted as described above, the vertical edges 1a', 1a' of the connecting roof panels 1, 1 are attached to a waste board (not shown). If the cover 14 is fitted to the waste board, the horizontal roof boards 1', 1' can be connected to the vertical edge parts 1b, 1b of the connecting roof boards 1, 1.

Therefore, the sealing material 11 is interposed between the fitting parts 2, 2 of the connecting roof panels 1, 1, and the fitting tool 12 is applied to the fitting parts 2, 2, which are abutted. Ingredients 1
2 is appropriately filled with a sealing material c, and the locking portions 5 and the engaging portions 6 on the front and rear edges of the connecting roof panels 1, 1 adjacent to each other in the inclination direction of the roof are locked, and the connecting roof panels 1, 1 are fitted horizontally. The descending ridge part a can be easily roofed by simply connecting the roofing plates 1' and 1', and the presence of the sealing material 11 and the fitting 12 allows good protection from rain.

In this way, when the eaves of the descending ridge part a is first constructed using the connecting roof panels 1, 1, the sealing material 11, the fitting 12, and the horizontal roof panels 1', 1' on both sides,
The locking portions 5, 5 on the rear edges of the connecting roof panels 1, 1 have the engaging portions 6, 5 on the front edges of the connecting roof panels 1, 1 located on the upper side.
Lock 6. In addition, a sealing material 11 is interposed between the fitting parts 2, 2 of the left and right connecting roof panels 1, 1 located on the upper side, and a fitting tool 12 is inserted between the fitting parts 2, 2 which are butted. Once fitted, the upper connecting roof panels 1, 1 can be installed.

Then, the connecting roof panels 1, 1 located on the upper side of the slope
Similarly to the above, the horizontal roof plates 1', 1' are connected to the vertical edges 1b, 1b by the scrap boards and the cover 14, and the roof is successively constructed in the upward direction of the slope of the descending ridge part a. be able to.

In addition, in the embodiment of the above drawing, the case where the descending ridge part a is constructed is explained, but the upright piece 3 of the fitting part 2 raised from the inclined edge 1a of the connecting roof board 1 is aligned with the valley part b. If it is bent at an angle slightly smaller than 90 degrees as shown in FIG.

That is, since the valley part has a shallow V-shape, the upright piece 3 of the fitting part 2 is erected at an angle slightly smaller than 90 degrees with respect to the connecting roof 1, and the connecting roof plates 1, 1 are lined up on the left and right. When forming a shallow V-shape and abutting the fitting portions 2, 2 of the respective connecting roof panels 1, 1, the two upright pieces 3, 3 face each other in parallel. The valley portion b can be formed by interposing the sealing material 11 between the fitting parts 2 and 2 in such a state and fitting the adherend 12.

In addition, when constructing the valley part b according to the present invention, if a long valley gutter is laid along the valley part b on the lower surface side of the connecting roof panels 1, 1, the rain will be shut off even more reliably. Become.

<Effects of the Invention> According to the method for constructing a roof plate connection part of the present invention,
When roof joints, such as roof ridges and valleys, can be easily installed using connecting roof sheets, sealants, and fittings, so even unskilled workers can connect accurately and reliably, and the connection can be made on-site. Since there is no need to cut the edge of the roof board diagonally, construction becomes extremely simple.

In addition, at the butt part of the left and right connecting roof plates,
Since the fitting piece is attached to the fitting and the fitting piece formed on the fitting part of the connecting roof board is exposed to the lower end of the fitting piece, rainwater does not get around and the rain is extremely well covered. Therefore, even if strong winds blow against the connection part during a rainstorm, the connection is strong and durable, and rainwater can be reliably prevented from entering.

Furthermore, by changing the shape of the attachment, it is possible to provide a roof with a wide variety of good looks.
