The verge parting material 3 includes a verge covering part 31 that covers the verge 1b, and a draining part 32 that is formed by bending one end of the verge covering part 31 on the gable side and covers the upper end of the existing gable board 17. .

The verge covering part 31 covers the verge 1b and includes a sloped part 31a that is inclined so that one end on the end side is slightly higher than one end on the opposite side, and a second end formed by bending the end of the sloped part 31a on the end side on the opposite side downward. 1 drooping portion 31b, and a return piece 31c formed by folding down one end of the inclined portion 31a on the side opposite to the first drooping portion 31b downward into a substantially V-shape. The inclined portion 31a is a portion that receives the load of rainwater and snow falling on the verge, and is prevented from deformation such as bending by the verge reinforcing material 5 disposed below. Further, the tip of the return piece 31c locks onto the upper end portion of the watertight material 6 when the verge parting material 3 is installed on the verge 1b. The width of the sloped portion 31a is not particularly limited, but it is preferably about 90 mm to 110 mm. With such a width, the verge 1b can be covered without any problem, and the sloped roof 1 has a clean appearance. It can be done.

The draining part 32 is formed by bending the lower end of the first hanging part 31b toward the gable side, and includes a fixing part 32a fixed to the upper surface of the existing covering material 16a and one end of the fixing part 32a on the gable side downward. It has a second hanging part 32b formed by bending, and a folded part 32c formed by bending the lower end of the second hanging part 32b toward the fixed part 32a side. The second hanging part 32b protrudes toward the gable side from the existing gable board 17 when the verge parting material 3 is installed on the verge 1b, and plays the role of a drainer that drains rainwater received at the fixed part 32a downward. .

The heat insulating material 4 shown in FIGS. 5 and 7 is a member made of polystyrene foam and having a substantially triangular cross-section, and is filled into a cavity between the new roof tile 2 and the existing roof tile 14. In addition, the upper surface 4a of the heat insulating material 4 has approximately the same shape as the lower surface 21a of the covering portion 21 of the newly installed roof tile 2, so that it can be fixed to the lower surface 21a when placed on the existing roof tile 14. Double-sided tape (not shown) is adhered to the upper surface 4a. The insulation material 4 is basically pre-cut to match the length of the newly installed roof tile 2 at a factory and brought in, but the insulation material 4 used at the end of the pitched roof 1 is cut into pieces. The parts will be cut on site. As shown in FIG. 5, the longitudinal edge 41 of the heat insulating material 4 is cut along the roof slope direction, and the cut edge 41 is used as the verge reinforcing material 5.

As shown in FIG. 5, the edge portion 41 of the heat insulating material 4 cut at a factory or construction site can be turned upside down so that the slope is reversed, thereby forming the verge reinforcing material 5. As shown in FIGS. 3 and 4, the verge reinforcing material 5 is installed between the verge covering part 31 and the newly installed roof tile 2 to prevent the inclined part 31a from being greatly bent by the snow load. can. Further, double-sided tape (not shown) is adhered to the lower surface 5a of the verge reinforcing material 5, so that it can be fixed to the upper surface 21b of the newly installed roof tile 2. At this time, since the verge reinforcement material 5 is a member obtained by inverting the heat insulating material 4, when the lower surface 5a of the verge reinforcement material 5 comes into contact with the upper surface 21b of the covering part 21 of the newly installed roof tile 2, the upper surface of the verge reinforcement material 5 5b naturally has an inclination angle that is substantially the same as the roof slope, and the verge covering portion 31 can be easily installed along the roof slope.

As shown in FIG. 3, the verge reinforcing material 5 is formed to have a width smaller than the width of the slope part 31a of the verge parting material 3. The width of the verge reinforcing material 5 is not particularly limited as long as it is smaller than the slope portion 31a, but it is preferably half or more of the width of the slope portion 31a, and more preferably about 50 mm or more. With such a width, deformation of the verge covering portion 31 due to snow load can be effectively prevented. Note that the verge reinforcing material 5 is basically processed to a predetermined size at a factory in advance and then transported to the construction site, but as described above, the heat insulating material 4 that is cut on site may also be used.

The watertight material 6 shown in FIGS. 3 and 8 is a member with excellent weather resistance and water resistance, and is a sheet-like foam made from ethylene propylene diene rubber. As shown in the figure, the shape of the watertight material 6 is formed according to the shape of the cavity formed between the verge covering part 31 and the newly installed roof tile 2. By closing the gaps, the waterproofness of the verge can be increased. Further, it is desirable that the watertight material 6 is formed in the same color as the newly installed roof tiles 2. By using such a color, it blends in with the roof surface 1a and makes the appearance of the pitched roof 1 look natural. can. In this application, the same color refers to a color that has the same measurement value in each color system standardized by JIS (Japanese Industrial Standards), or a standard color for paints specified by the Japan Paint Manufacturers Association. In addition to colors that have the same color chart number, this also includes colors that a person visually perceives as being substantially the same even if the measured values or color chart numbers are different.

Next, a method for reinforcing the verge parting material will be explained. First, as shown in FIG. 5, the edge portion 41 of the heat insulating material 4 is cut along the roof slope direction so as to have approximately the same length as the newly installed roof tile 2 at a factory or construction site. Then, the verge reinforcing material 5 is formed by inverting the edge portion 41 of the cut heat insulating material 4 upside down so that the slope faces in the opposite direction.

Subsequently, as shown in FIG. 3, a new asphalt roofing 7 is laid on the existing roof tile 14, and a sacrificial iron plate 33 having a substantially L-shaped cross section is attached to one end of the existing covering material 16a on the existing roof tile 14 side. Install. The sacrificial iron plate 33 has a vertical portion 33a that rises above the upper surface of the existing sheathing material 16a and contacts the one end of the existing sheathing material 16a, and a vertical portion 33a that protrudes from the lower end of the vertical portion 33a toward the existing roof tile 14 side, and is connected to the new asphalt roofing 7. By abutting the vertical part 33a inside the first hanging part 31b of the verge covering part 31, the strength of the first hanging part 31b can be increased.

Then, as shown in FIG. 7, the upper surface 4a of the insulation material 4 is fixed to the lower surface 21a of the covering part 21 of the new roof tile 2 with double-sided tape, and the insulation material 4 and the new roof tile 2 are sequentially attached to the existing roof tile 14 from below the water. Install it on top. At this time, the new roof tile 2 fits the tile locking piece 22b of the underwater side hooking piece 22 into the tile locking groove 23a of the new roof tile 2 located on the underwater side, and connects the above water side hooking piece 23 to the existing roof tile. By fixing to the tile 14 with screws, it can be fixed to the roof surface 1a.

As shown in FIG. 8, when the new roof tiles 2 are installed on the entire roof surface 1a, when the verge parting material 3 is installed on the verge 1b, it is watertight at the location where one end 31d of the verge covering part 31 shown in FIG. 3 is located. The lower surface of the watertight material 6 is fixed to the newly installed roof tile 2 with double-sided tape. Next, as shown in FIG. 3, the lower surface 5a of the verge reinforcing material 5 is fixed to the upper surface 21b of the newly installed roof tile 2 located on the verge 1b with double-sided tape. At this time, as mentioned earlier, the verge reinforcing material 5 is a member obtained by inverting the heat insulating material 4, so when the lower surface 5a comes into contact with the upper surface 21b of the newly installed roof tile 2, the upper surface 5b naturally becomes approximately the same as the roof slope. It will form an inclined angle. Then, the inclined part 31a and the fixing part 32a of the verge parting material 3 are placed on the verge reinforcing material 5 and the existing covering material 16a, respectively, and fixed with the screws 15, thereby completing the reinforcing structure A of the verge parting material. let

Note that the verge parting material 3 may be installed prior to the verge reinforcing material 5. In that case, first, after installing the new roof tiles 2 on the entire roof surface 1a, cover the existing sheathing material 16a of the existing verge drainage material 16 with the drainage part 32 of the verge parting material 3, and cover the fixed part 32a with the existing sheathing material 16a. Fix it to the top surface of 16a with screws. Then, the verge reinforcing material 5 is pushed into the gap between the newly installed roof tile 2 and the verge covering part 31, and finally, the watertight material 6 is fixed to one end 31d of the verge covering part 31 to form the reinforcing structure A of the verge parting material. Finalize. By using this construction procedure, if you want to install the verge parting material 3 first in relation to other parts, or if it is necessary to reinforce the verge 1b after constructing the sloped roof 1, you can install it later. The verge reinforcing material 5 can be installed, and workability can be improved.

As described above, in the sloped roof reinforcement structure 1 of the present application, the verge reinforcement material 5 is installed between the verge covering part 31 of the verge parting material 3 and the newly installed roof tile 2, so that the deformation of the verge parting material 3 due to the snow load is prevented. can be effectively prevented. The verge reinforcing material 5 can be formed by simply cutting and inverting the solid heat insulating material 4, so there is no need to create new members to reinforce the verge, and Since the surplus heat insulating material 4 that is discarded can be effectively utilized, it is possible to create a structure with excellent economical efficiency. Furthermore, since the verge reinforcing material 5 is a member obtained by inverting the heat insulating material 4, the upper surface 5b of the verge reinforcing material 5 can naturally have an inclination angle that is approximately the same as the roof slope, and the verge covering portion 31 can be easily attached. can be installed. Since the verge reinforcing material 5 is installed between the draining part 32 and the watertight material 6, it is not visually recognized from the outside, and the design of the pitched roof 1 can be improved.

The embodiments of the present invention are not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the idea of the present invention.

The decorative curtain board material, the reinforcing structure for the verge parting material, and the method for reinforcing the verge parting material according to the present invention can be suitably used when forming sloped roofs in areas with heavy snowfall.
