[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0021]
1 to 4 show an embodiment of the present invention.
[0022]
1 and 2, reference numeral 1 is a building, and this building 1 has the same configuration in many respects as the conventional technology described above with reference to FIGS. 5 and 6. The description is omitted.
[0023]
Each tile 16 to be laid on the surface of the existing tile 6 which is the surface of the existing roof 2 by the new tile laying method has the following configuration.
[0024]
In FIG. 3, the tiles 16 are made of sheet metal, have a rectangular shape in plan view, and have the same shape and size. Each of the tiles 16 has a bulging portion 17 that bulges outward from the roof 2 at the upper part in the inclination direction A of the roof 2, and at the lower edge of the roof 2 in the inclination direction A of the roof 2. It has the bending part 18 bent toward the direction. The bulging portion 17 and the bent portion 18 are formed over substantially the entire width of the roof tile 16 in the left-right direction.
[0025]
In FIGS. 1 and 2, when the tiles 16 are laid along the inclination direction A, the upper tile 16 adjacent to the tile 16 is formed in the bulging portion 17 of the lower tile 16 among the tiles 16. The bent portion 18 is externally fitted from the outside. Thereby, it is prevented that a gap is generated between the tiles 16 and 16 in the inclination direction A, and the rainwater that has poured onto the tiles 16 sequentially flows on the surface of the tiles 16 below and flows toward the eaves side. Drained.
[0026]
1-4, among the tiles 16, the tiles 16 laid along one side of the roof 2 are processed as follows.
[0027]
That is, as shown in FIG. 3, a pressing force B by a hammer or the like is applied to the bulging portion 17 at the edge 19 on the wall 3 side of the roof tile 16. Then, the bulging portion 17 is pressed and deformed into a flat shape as shown in FIG. 4 (portion indicated by reference numeral 17 'in FIG. 4).
[0028]
Further, at the cutting portion C indicated by the alternate long and short dash line in FIG. 3, the bent portion 18 at the end edge portion 19 of the roof tile 16 is removed by cutting with a gold pin or the like, and the end edge portion 19 is removed as shown in FIG. 4. The thickness is approximately the plate thickness.
[0029]
The edge portion 19 of the roof tile 16 is bent toward the roof 2 when viewed from the general portion 21 that is a non-processed portion of the roof tile 16. In this case, the end edge 22 on the free end side of the end edge portion 19 is positioned substantially at the same position as the extended surface obtained by virtually extending the lower surface of the general portion 21 of the roof tile 16.
[0030]
Moreover, the sealing material 23 is attached to the upper surface of the edge 22 of the edge part 19 of the said roof tile 16 by sticking.
[0031]
1 and 2, the edge 19 of the tile 16 processed as described above is inserted into a gap 24 between one side of the roof 2 and the vertical piece 14 of the rain pressure plate 12 (each Arrow D) in the figure.
[0032]
According to the above-described new tile laying method, since the bulging portion 17 is flattened and the bent portion 18 is cut and removed at the edge 19 on the wall 3 side of each tile 16, the tile The 16 edge portions 19 have a thin shape as a whole.
[0033]
Therefore, when the edge 19 of the tile 16 is inserted into the gap 24 between one side of the roof 2 and the laterally facing piece 13 (arrow D in FIGS. 1 and 2), the gap 24 is slightly pushed. Even if it is spread out or remains in the existing state, the insertion can be performed, whereby a new tile 16 is laid along one side of the roof 2. That is, it is not necessary to cut and remove the lower edge portion 8a of the outer wall member 8 or to replace the existing rain retainer plate 12 with a new one as in the prior art.
[0034]
Further, as described above, the end edge portion 19 of each tile 16 is bent toward the roof 2 when viewed from the general portion 21 of each tile 16.
[0035]
For this reason, when viewed in a direction perpendicular to the roof 2, the dimension from the virtual extension surface of the lower surface of the tile 16 to the upper surface of the end edge 22 on the free end side of the end edge portion 19 of the tile 16 is extremely small, that is, Since the thickness of the end edge 22 of the end edge portion 19 is reduced, even if the gap 24 is narrow, the end edge portion 19 of the roof tile 16 can be easily inserted into the gap 24 from the end edge 22 side. The gap 24 is narrower and sufficient.
[0036]
Therefore, when the end edge 19 of the roof tile 16 is inserted into the gap 24, the work of expanding the gap 24 becomes unnecessary.
[0037]
Further, as described above, the sealing material 23 is attached to the surface of the end edge portion 19 of each roof tile 16.
[0038]
For this reason, when the edge 19 of the roof tile 16 is inserted into the gap 24, the sealing material 23 is brought into pressure contact with the lower surface of the headboard 11 on the side of the laterally facing piece 13 of the rain retainer plate 12, and the gap 24 is It is sealed more reliably.
[0039]
In addition, as described above, since the thickness of the end edge 22 of the end edge portion 19 is thin, even if the sealing material 23 is attached as described above, the insertion into the gap 24 can be easily performed.
[0040]
【The invention's effect】
The effects of the present invention are as follows.
[0041]
The invention of claim 1 includes a roof in which the building is inclined downward toward the front, and a wall extending upward from one side portion in the left-right direction of the roof, the wall being a wall main body, and the wall main body A sheet metal rain retainer plate extending in the inclined direction along one side portion of the roof, and the rain retainer plate is horizontally oriented in the front cross section. And a vertical piece extending upward from one end of the horizontal piece, the horizontal piece is placed on the surface of one side of the roof, and the vertical piece is the wall body and the outer wall material. A new tile laying method for an existing roof in which the tile is laid on the surface of the roof when inserted between the lower edge of the roof, and the tile is made of sheet metal, and the inclination direction of the roof And has a bulging portion that bulges outward from the roof of the same as above, and It has a bent portion bent toward the roof at the lower edge in the oblique direction, and when laying a plurality of tiles along the inclined direction, among these tiles, on the bulge portion of the lower tile, The bent portion of the upper tile is externally fitted, and the bulging portion at the edge portion on the wall side of each tile laid along one side portion of the roof is pressed and deformed into a flat shape, and the above The bent portion is cut and removed, and the edge of each tile is inserted into the gap between the one side portion of the roof and the laterally facing piece of the rain retainer plate.
[0042]
That is, at the edge portion on the wall side of each tile, the bulging portion is flattened and the bent portion is cut and removed, so that the edge portion of the tile becomes a thin shape as a whole.
[0043]
Therefore, when the edge of the tile is inserted into the gap between one side of the roof and the laterally facing piece of the rain retainer plate, the gap is slightly expanded or even in the existing state, The above insertion is possible, whereby a new tile is laid along one side of the roof. In other words, unlike the conventional case, it is not necessary to cut and remove the lower edge portion of the outer wall material or to replace the existing rain retainer plate with a new one, so that the work by this construction method can be performed easily and inexpensively.
[0044]
In the invention of claim 2, the end edge portion of each tile is bent toward the roof as seen from the general portion of each tile.
[0045]
Therefore, when viewed in a direction perpendicular to the roof, the dimension from the virtual extension surface of the lower surface of the tile to the upper surface of the edge on the free end side of the edge of the tile is extremely small, that is, the end of the edge portion. Since the thickness of the edge is reduced, even if the gap is narrow, the edge portion of the roof tile can be easily inserted into the gap from the edge side, and the gap is narrower.
[0046]
Therefore, when the edge of the roof tile is inserted into the gap, the work of expanding the gap becomes unnecessary, and as a result, the work by this method is further facilitated.
[0047]
In a third aspect of the present invention, a sealing material is attached to the surface of the edge portion of each tile.
[0048]
For this reason, when the edge part of a roof tile is inserted in a clearance gap, the said sealing material will be press-contacted to the horizontal direction one side of a rain retainer board, and the said clearance gap is sealed more reliably.
[0049]
Therefore, the drainage between the one side portion of the roof and the lower edge portion of the outer wall material is more reliably performed while being easy to work and inexpensive.
[0050]
In addition, as described above, since the thickness of the edge of the edge portion is thin, even if the sealing material is attached as described above, the insertion into the gap can be easily performed.
