Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a folded roofing board used for roofing buildings.

[Conventional technology]

Conventionally, folded roof shingles have been arranged side by side on a beam body, and the side edges of adjacent folded roof shingles have been overlapped and tightened together to form a roof. If the folded roof shingles above have been installed and the roof is to be replaced due to corrosion, the corroded folded roof shingles should be removed and new folded roof shingles should be installed, or the folded roof shingles should be replaced with new folded roof shingles. Generally, a method was adopted in which a body green, tight frame, etc. were further installed on top of the roof shingles, a new roof was completely overlaid on the old roof, and new folded roof shingles were installed.

[The problem that the idea attempts to solve]

However, in the former conventional example, not only does the reroofing work take much time for the worker, but the building cannot be used during the reroofing process.
Furthermore, the latter conventional example has the problem of high construction costs and material costs required for reroofing.

The present invention was made in consideration of the above-mentioned conventional problems, and was made by focusing on the fact that corrosion of folded roof shingles usually concentrates in the valley portions. The object of the present invention is to provide a folded roof shingle structure that allows for easy re-roofing work, allows for low-cost re-roofing, and provides a more solid re-roofing condition. be.

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the structure of the folded roofing board of the present invention is such that the folded roofing board has a chevron pattern in the midsection between the mountain-shaped part and the valley-shaped part from the side edge of the valley-shaped part. The upper edge of the valley-side slope slopes upward in the width-widening direction toward the bottom, and the top edge of the valley-side slope slopes downward from the side edge of the mountain-shaped part toward the valley-shape part at an angle of inclination that is approximately the same as the valley-side slope. A folded portion having a Z-shaped cross section is provided in which the lower edge of the extending mountain side slope is interconnected with a folded surface portion. When the printing plate is stacked above the valley side area, the folding surface is arranged so that the side end of the folding plate for reroofing is sandwiched between the upper edge of the lower slope and the folding surface. is characterized in that it is formed in a shape that extends downward in the narrow width direction from the upper edge of the valley side slope and continues to the lower edge of the mountain side slope.

[Effect]

In the structure of the above-mentioned folded roofing board, the folding board for reroofing having a cross-sectional shape along the valley side region from the valley part to the upper edge of the lower sloped surface of the folded roofing board is attached to the above-mentioned valley side region. Only the valley side area of the folded roof shingles can be partially reroofed by stacking them on top of each other and sandwiching the side edges between the upper edge of the lower slope and the folded surface. . Therefore, the re-roofing work can be easily carried out, thereby significantly reducing the cost of materials and the cost required for the re-roofing work.
In addition, in the above, the side edge of the folding plate for reroofing is
By being sandwiched between the upper edge of the lower sloped surface and the folded surface, these side edges are attached to each other without wobbling, and as a result, for example, due to molding errors, etc., Even if there is a slight difference in the inclination angle or width of the folded plate from the pre-roofed roof plate, the entire folded plate for re-roofing will adhere more firmly to the pre-roofed roof plate. It can be in the installed state.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

At both left and right ends of the folded roofing board 1,
Upper end bent portions 2 and 3 are formed to form tile bar-shaped chevron-shaped portions, respectively. A large number of the above-mentioned folded roofing boards 1 are arranged side by side, and by overlapping the upper end bent parts 2 and 3 formed at each side end and tightening them, as shown in FIG. A folded roof is formed by alternately and continuously forming tile bar-shaped mountain-shaped portions and valley-shaped portions. A valley part is formed by the bottom part 4 of the above-mentioned folded roofing board 1, and a side part 1a corresponding to the midsection between the tile bar-shaped peak part and the valley part is formed.
A folded portion having a Z-shape in cross section is formed so that the left and right end portions of the folding plate 6 for re-roofing can be respectively engaged.

The above-mentioned folded-back shaped portion is an upper edge of a valley-side inclined surface that extends upwardly in the width-widening direction from the side edge of the bottom portion 4 forming the valley-shaped portion toward the upper end bent portions 2 and 3 forming the mountain-shaped portion, respectively. and the lower edge of the mountain side slope which extends downwardly at an angle of inclination almost the same as the valley side slope from each side edge of the upper end bent parts 2 and 3 toward the bottom part 4 at the folded surface part 5. It is formed in a connected shape. The folded surface portion 5 has a shape that extends from the upper edge of the valley side slope in the narrow width direction and in the downward slope direction and continues to the lower edge of the mountain side slope.

Then, as shown in FIG. 3, a folding plate 6 for re-roofing, which is formed to follow the shape of the bottom 4 and the upper edge of each lower slope on both sides thereof, is stacked on top of the bottom 4, and By making the end portions 6a, 6a sandwiched between the upper edge side of the lower inclined surface of the side surface portion 1a and the folded surface portion 5, it is possible to partially roof only the valley side area. It is designed to be repairable.

In the above configuration, the folded roofing board 1 has a second
As shown in the figure, by overlapping the upper bent portions 2 and 3 of adjacent folded roofing plates 1 and tightening them together, the tile bar-shaped mountain portions and valley portions are alternately continuous. The roof is covered with a folded roof made of wood.

In the above folded roof, each folded roofing board 1...
The valley-shaped portion of ... forms a flow path for rainwater, etc., and is therefore susceptible to corrosion. Therefore, when this valley part corrodes, a third
Install the re-roofing folding plate 6 as shown in the figure,
Both ends 6a, 6a of this re-roofing folding board 6 are respectively engaged with the folded portions of the folding roofing board 1 from below, and the re-roofing folding board is attached to the lower half of the folding roofing board 1. The roof is reroofed by fitting the board 6 and reroofing a part of the folded roof. The above-mentioned folding plate for re-roofing 6 is the same as the folding plate roofing plate 1.
A rust preventive agent 7 is coated on the side facing the valley-shaped portion, so that the folded roofing board 1 and the folded roofing board 6 for re-roofing are insulated. This makes it possible to effectively prevent corrosion after the reroofing folding plate 6 is reroofed. In addition, the above rust preventive agent 7
Instead, it is also possible to enhance the heat insulation function of the roof by attaching a heat insulating material to the lower surface of the reroofing folding board 6. If the above-mentioned re-roofing folding plate 6 becomes corroded over time, it is sufficient to replace the re-roofing folding plate 6 with a new re-roofing folding plate and re-roofing.

In addition to the construction method described above, for example, when roofing with the folded roofing board 1, the re-roofing folding board 6 is fitted into the valley part of the folded roofing board 1 from the beginning as described above. However, if the folding plate 6 becomes corroded, a method may be adopted in which the folding plate 6 is replaced with a new one. In this case, the folded roofing board 1 can avoid a situation where only the valley portion corrodes early, thereby extending the life of the roof and reliably eliminating the risk of water leakage. Become.

As explained above, in the above embodiment,
In the midsection between the mountain-shaped part and the valley-shaped part of the folded roofing board 1, both side ends 6a of the folded roofing board 6 for re-roofing,
A folded portion having a Z-shaped cross section is formed so that the portion 6a can be attached thereto. Therefore, since it is possible to partially reroof only the valley side area of the folded roof shingle 1, the reroofing work can be easily carried out, which results in a significant reduction in material costs and the cost of reroofing work. The cost required for this can be significantly reduced. Furthermore, even if an expensive corrosion-resistant metal such as stainless steel is used as the re-roofing folding plate 6 that is re-roofed in the valley-shaped portion of the folded roofing plate 1, the amount of material used is small, so the cost does not increase so much. Furthermore, it is also possible to provide the folded roofing plate with the respective functions by providing a rust preventive agent, a flame insulating material, etc. on the lower surface of the folded roofing plate for re-roofing.

Further, in the above embodiment, both ends 6a, 6a of the folding plate for re-roofing 6 are formed from both sides by the upper edge side of the lower sloped surface of the side surface 1a of the folding plate roofing plate 1 and the folded surface part 5. By being in the sandwiched state, these both side end portions 6a, 6a are fixed in a state where no wobbling occurs.
For example, even if there is a slight difference in the inclination angle or width of the re-roofing folding plate 6 from the pre-roofed roof shingles due to molding errors, etc., the entire re-roofing folding plate 6 may be pre-roofed. The re-roofing can be re-roofed in such a way that noise generation due to vibration of the re-roofing folding plate 6 is suppressed, for example.

[Effect of idea]

As described above, the structure of the folded roofing board according to the present invention is such that the folded roofing board has a structure that extends from the side edge of the valley part to the midsection between the mountain part and the valley part in the folded roofing board. The upper edge of the valley-side slope extends upward in the direction of width expansion, and the mountain side extends downward from the side edge of the mountain-shaped part toward the valley-shaped part at an angle of inclination that is approximately the same as the valley-side slope. A folding plate for reroofing is provided with a folded section having a Z-shaped cross section, in which the lower edge of the inclined surface is connected to the lower edge of the inclined surface by a folded surface section, and whose cross section is along the valley side region between the valley section and the lower inclined surface. The folded surface portion is arranged such that when the folded plate for reroofing is stacked above the valley side area, the side end of the reroofing folding plate is sandwiched between the upper edge of the lower sloped surface and the folded surface portion. This configuration is formed in a shape that extends downward in the narrow width direction from the upper edge of the valley side slope and continues to the lower edge of the mountain side slope.

As a result, it is possible to partially reroof only the valley side area of the folded roof shingles, making the reroofing work easier.This results in a significant reduction in material costs and the cost required for reroofing work. can be significantly reduced. In addition, in the above, the side edges of the folding plate for reroofing are sandwiched between the upper edge side of the lower sloped surface and the folded surface, so that these side edges are attached to each other without touching each other. Therefore, even if there is a slight difference in the inclination angle or width of the re-roofing folding plate from the pre-roofed roof board due to molding errors, etc., the entire re-roofing folding plate will be This has the effect that it can be attached more closely and firmly to the roof shingles being covered.
