Description

[Detailed Description of the Invention] <Industrial field of application> This invention is a single-piece roof tile that overlaps with a part along the gable side edge (keraba) of a gable roof that is covered with flat plate roof tiles. At the same time as fixing this roof tile to the base plate,
The present invention relates to a metallic plate glazed cover for a roof tile that prevents rainwater from entering under the roof tile.

<Prior Art> Flat plate roof tiles using the shivering cover of the present invention are commercially available as Colonial (trade name of Kubo Iron Works Co., Ltd.) and National Fulvest (trade name of Matsushita Electric Works Co., Ltd.).
The fluff covers used for these roof tiles are known from Japanese Utility Model Laid-Open No. 60-70111.

As shown in FIG. 6, the publicly known fluff cover is bent at a right angle downward from an upper surface piece 1 along a flutter side side upper surface of a roof tile and a flute side edge of the upper surface piece. It has a side piece 2 along a side surface parallel to the fluff of the roof tile, and a folded-back fitting portion 3 for wrapping the descending end portion of the roof tile in a U-shape is connected to the front end of the top piece.

<Problems to be Solved by the Invention> The side piece 2 of the fluffy cover is a horizontally long rectangle, and its lower edge 2'is parallel to the upper edge 1 or the upper edge of the side piece, and is located inside the lower edge 2 '. Is formed by folding back the draining groove 4.

Therefore, the upper surface of the lower half is exposed, and the upper tiles are placed on the overlapping part of the upper half. For example, in order to be able to attach the cover, the downward direction and length of the side piece 2 and the size of the groove 4 inside the lower edge of the side piece must be different.

This is because, as shown in FIG. 6, the second step from the bottom of the roof tile F ₁ fixed on the roofing sheet of the base plate A is also overlapped with the overlapping portion of the roof tile F ₁ and fixed on the base plate. Roof tile
The downward length l ₂ of the side piece C ₂ -2 of the glazed cover C ₂ attached to F ₂ is the downward length l of the side piece C ₁ -2 of the glazed cover C ₁ attached to the bottom plate tile F _1. Longer than ₁ and cover C ₂
This is because it is necessary to increase the size of the groove 4 in order to receive and fit the groove 4 of the cover C ₁ . This relationship is 3 from the bottom
If it is attached to the _third- tier tile F ₃ and the second-tier tile F ₂ from below, the covers C ₃ and C ₂ , the fourth-tier tile F ₄ from the bottom, and the third-tier tile F ₃ from the bottom If you want to install them on the covers C ₄ and C _{3 respectively}
The same is needed between.

In other words, the above-mentioned conventional fluff cover has to be manufactured in a very troublesome manner because it is necessary to increase the downward length of the side piece as well as the groove provided inside the lower edge of the side piece as it is attached to the upper plate tile. It is necessary and costly. In addition, it is necessary to store the keraba cover separately for the lowermost stage, the second stage, the third stage, ...

Furthermore, since the downward length of the side piece is longer than that attached to the upper plate tile, the appearance of the construction state looks like a series of thick squares gradually increasing toward the top of the girder,
It is monotonous.

<Means for Solving the Problems> The present invention relates to an improvement of the above-described known gutter cover, and includes an upper surface piece (11) along the upper surface of the side part of the roof side of the roof tile, and a side of the upper surface piece on the side of the gutter side. It has a side piece (12) that bends at a right angle downward from the edge and extends along the side parallel to the fluff of the plate tile, and at the front end of the upper surface piece, a fold-back fit that wraps the falling end of the plate tile in a U shape. In the metal plate girder cover for the roof tiles to which the joint portion (13) is connected, the side piece (12) has a downward length that is sufficiently large at the front end (12a) with respect to the thickness of the roof tile. It is a slender trapezoid with a slightly larger size at the end (12b), and an inward folding piece (14) folded inward is provided at the lower edge (12 ') of the side piece, and the inward width of this inward folding piece. Is a trapezoid with a wide front end and a narrow rear end. At the front end of the inward bending piece (14), fold an upward engaging piece (15) that is adjacent to the side piece (12) at a right angle. Vertical, upward projecting portion (1 away from the upper edge of the upward engagement piece (15 ') to the side piece (12)
9) is provided and when the front cover front part is inserted into the rear part of the lower cover by the required amount, the side piece (12) of the lower cover has the folded fitting part (13) at the front end of the upper cover and the upward engaging piece (1).
5) It is sandwiched between the upper edge and the inward bent piece (1
4) is characterized in that it is sandwiched between the side piece (12) at the front end of the upper cover and the upward protruding portion (19) to be restrained. The side piece (12) of the upward protrusion (19).
It is preferable that the side surface (19 ') facing toward is inclined so as to gradually approach the side piece upward.

<Embodiment> In FIGS. 1 to 5, reference numerals 11 and 12 denote an upper surface piece and a side surface piece, which are bent at substantially the same angle as that of the above-mentioned known glazed cover. This Keraba cover is a copper plate with a thickness of 0.3 to 0.5 mm,
It is a bent product of a metal plate such as a stainless steel plate or a galvanized steel plate, and a folded-back fitting portion 13 that wraps the descending end portion of the roof tile in a U shape is connected to the front end of the upper surface piece 11.

The downward length la at the front end 12a of the side piece 12 is sufficiently large with respect to the thickness t of the roof tile F, and the downward length lb at the rear end 12b is slightly larger than the thickness t of the roof tile. As a result, the lower edge 12 'of the side piece is inclined uphill with respect to the upper surface piece 11 or the upper edge of the side piece, and the side piece 12 has an elongated trapezoidal shape. Inside the inclined lower edge 12 ', an inward bending piece 14 bent at a right angle is connected so as to reinforce the side piece. The inward width of the inward bent piece 14 is wide at the front end 14a and narrow at the rear end, whereby the inner edge 14 'is inclined with respect to the lower edge of the side piece 12, and the inward bent piece as a whole also. As shown in the figure, the standard shape of the narrow roof tile F is a baseball home base shape with a thickness t of about 5 mm, a width W of about 90 cm, and a length L in the front-rear direction of both sides of about 23 cm. The length L'in the front-rear direction at the top F ₁ of the end is about 45 cm, and the distance from the front edge of the boundary F ′ between the exposed portion Fa exposed on the roof and the subsequent overlapping portion Fb where the upper plate tile overlaps When L ″ is 18 cm, for example, the upper surface piece 11 has a width W ₁
Is about 7 to 8 cm, the length l is about 23 to 33 cm, and the front end 12a of the side piece 12 is
The downward length la is about 2.5-3.0 cm, the downward length l of the rear end 12b
b is about 6 mm, which is almost the same as the thickness of the roof tile, and the inward width of the inward facing piece 14 is about 15 mm at the front end 14a and about 6 mm at the rear end 14b.

Then, at the front end of the inward bent piece 14, bent upward, provided with an upward engaging piece 15 adjacent to the side piece 12 at a right angle,
This upward engaging piece has a distance Lc measured from the front end of the side piece 12.
An upper edge portion 1 that keeps a vertical gap 16 corresponding to the downward length lc (see FIG. 1) between the folded back fitting portion 13 and the front end of the lower surface.
5'and an upwardly projecting portion 19 adjacent to the upper edge 15 'and spaced from the side piece 12 are provided.

The width of the upper edge portion 15 'of the upward engaging piece is adjusted to the inward width of the middle portion of the inward bending piece at the same position as the distance Lc measured from the front end of the inward bending piece 4.

Distance Lc in the middle of distance Lc measured from the front end of the side piece
Is the length L ″ from the front edge f ₂ of the roof tile to the boundary F ′ between the exposed portion Fa and the overlapping portion Fb and the length l ′ in the front-rear direction of the folded piece 13 ′ of the folded fitting portion 13, and L It is preferable to set the value a little shorter than the value of "-l '". Therefore, the folded-back fitting portion of the upper cover and the front half of the inwardly bent piece should be located outside the latter half of the lower cover so that the upward protruding portion 19 is located inside the inner edge of the inwardly bent piece. When the side pieces of the upper cover are brought into contact with each other and then the upper cover is moved forward, the side pieces of the upper cover and the front ends 12a of the inward folding pieces are separated from the front ends of the side pieces of the lower cover. When it coincides with the position of Lc (broken line in FIG. 1), the side piece 12 of the lower cover is located on the lower surface of the folded portion 13 ′ of the folded fitting portion of the upper cover and the upper edge portion 15 ′ of the upward engaging piece. At the same time, the side surface 19 'of the upward protruding portion of the upper cover is also close to the inner edge 14' of the inwardly bent piece of the lower cover, and the folded-back fitting portion of the upper cover.
The rear end of the folded piece 13 'of 13 is slightly separated from the boundary F'between the exposed portion Fa and the overlapping portion Fb of the roof tile by a distance slightly shorter than the value of L "-l'.

For roofing, the roof tiles S for starters, which are almost the same shape as the overlapping portion Fb of the roof tiles, are arranged and fixed in a row along the eaves on the lower end of the base plate A on which a roofing sheet has been laid, and fixed on top of that. On the other hand, the width of the roof tiles is shifted by half and the roof tiles at the bottom are stacked and arranged in a horizontal row. Then, while wrapping the front end portion of the side portion on the side of the glazed side of the tile tile F ₁ located on the side of the glazed side with the folded-back fitting portion 13 of the glazed cover, the side piece 12 thereof is brought into contact with the side portion and runs along. The nail hole 18 in the upper surface piece 11 is aligned with one of several nail holes 17 opened laterally at a predetermined interval in the overlapping portion Fb of the plate roof tile F ₁ , and the nail is inserted through the nail holes 18 and 17. The cover C ₁ is fixed by driving it into the base plate A and loosening it together with the roof tile. Of course, other horizontal tiles in a row are also fixed to the base plate with nails inserted from the nail holes 17.

In this way, when the lowermost step is roofed, the width is shifted halfway over the overlapped part Fb and the second step is overlapped so that they are arranged in a horizontal row, and the upward projecting portion 19 of the cover is the inner side of the inward bent piece of the lowermost cover. The roof tile that is located on the side of the gab
If the front end of the side part of F ₂ is fluffed, it is wrapped with the folded fitting part 13 of the cover C ₂ and its side piece 12 is already attached to the cover C ₁
The side wall of the roof tile F ₂ is brought into contact with the side of the roof tile F ₂ through the side piece, and is fixed to the base plate with nails driven from the nail holes 17 and 18 in the same manner. After that, the same process is repeated, and the third and fourth stages ... the uppermost stage is roofed, and the glazed cover is attached to the side part of the glazed side of each of the glazed sides. It is fixed to the board together with.

The second stage, and to mount the verge cover the subsequent plate tile F _2, F ₃ ... verge side portion of FIG. 1, as indicated by the broken line in FIG. 3, folding the cover the rear end of the folded piece 13 'of the fitting portion 13 is fitted from the side in front of the fixed pre-cover as described above so as to be located slightly before the front edge f ₂ such Itakawara F _2, F _3, then mallets And the like, the front end of the folded fitting portion 13 is hit backwards as shown by the arrow to retract the cover, and the folded piece 13 'is inserted between the lower surface of the roof tile and the upper surface of the overlapping portion 7b of the front roof tile. By wrapping the front end portion of the side portion of the roof tile on the glazed side with the folded back fitting portion 13, the construction can be easily performed.
Of course, at the beginning of hitting the folded-back fitting portion 13 backward, the front edge of the roof tile may be slightly floated, and a gap into which the folded-back piece 13 'penetrates may be formed between the folded roof tile and the overlapping portion Fb of the lower tile.

In this way, if the side cover is attached along the side of the side of the roof tile on the side of the side of the roof tile that overlaps the overlapping portion of the lower side roof tile, the side cover piece is attached to the top tile of the cover. And the side piece covers and protects the edge of the roof tile on the glazed side, and at the same time prevents rainwater from entering between the roof tile and the roof plate. Then, in the installed state, the folded back fitting portion 13 at the front end of the top piece of each cover wraps and supports the side front end of the roof side of the roof tile in a U-shape, and also the rear bottom surface of the top piece and the inward folding. The upper surface of the rear portion of the curved portion (14) supports the overlapping portion of the roof tile by sandwiching the middle portion of the side portion on the side of the gutter. This improves the attachment strength of the cover to the roof tile. Further, the downward length of the middle of the side piece of the lower cover, which passes through the space 16 between the upper edge of the upper engagement piece 15 of the upper cover and the lower surface of the front end of the folded fitting portion 13, is the distance 16 mentioned above. A little smaller than the vertical length of
As a result, a slight gap is created between the upper edge portion 15 'of the upper fluff cover cover and the front end of the lower surface of the folded back fitting portion 13 of the lower cover. Side surface 19 'of the upward protruding portion 19 provided on the inner side edge 14' of the inward bending piece formed inside the side surface piece of the lower cover.
Although a slight gap is created between the side piece 12 and the side piece 12 of the cover when the wind blows, the side piece 12 on the upper stage is bent by the wind force and is provided on the inward bending piece connected to this. The upper edge portion 15 'of the upward engaging portion and the upward protruding portion 19 adjacent to the upper edge portion 15'.
The side surface 19 'engages the lower surface of the inward folding piece 14 of the lower cover and the inner edge 14' thereof to withstand the wind force, and the roof tile and the cover are not blown off even by the strong wind.

Furthermore, the lower edge of the side piece 14 slopes uphill with respect to the upper edge and its downward length decreases towards the rear. The rear portion of the lower cover including the side surface piece 12, the upper surface piece 11, and the inward bending piece 14 is provided between the lower surface of the folded-back fitting portion of the upper cover and the upper edge portion 15 ′ of the upward engaging piece. Since it is attached to the side of the roof tile of each step through the gap 16 on the side of the shingles, it is sufficient to mold the shroud cover to be attached to any of the steps of the roof tiles to the same size, which results in complicated manufacturing, storage, and construction. Is eliminated.

Then, when the side surface 19 'of the upward protruding portion 19 is placed so as to be inclined upward so as to gradually approach the side surface piece 12 as shown in the drawing, the inner edge 14' of the inward bending piece 14 is stronger than this side surface. Since it comes into contact with 19 ', it is possible to further increase the resistance to the wind blown inside the side piece 13.

In addition, at the time of construction, the starter plate tiles are fixed adjacent to the width of the eaves side of the base plate A, but the side parts of the plate tiles F ₁ , F ₂ ... It is preferable to make it extend 2-3 cm outward from the side portion of the ground plate on the side of the fluff to prevent the upward engaging portion 19 from interfering with the ground plate.

<Effect of device> According to the glazed cover of the present invention, the top surface piece 11 and the side surface piece 12 cover and protect the edge part of the roof tile of the roof tile side, and at the same time, rainwater enters between the roof tile and the roof plate. Prevent the.
Then, in the installed state, the folded back fitting portion 13 at the front end of the top piece of each cover wraps and supports the side front end of the roof side of the roof tile in a U-shape, and also the rear bottom surface of the top piece and the inward folding. The upper surface of the rear portion of the curved portion (14) supports the overlapping portion of the roof tile by sandwiching the middle portion of the side portion on the side of the gutter. This improves the attachment strength of the cover to the roof tile. Further, since the rear portion of the lower cover passes through the gap 16 between the upper edge portion 15 'of the upwardly facing engagement piece 15 of the upper cover and the lower surface of the front end of the folded fitting portion 13, the rear portion of the lower cover passes therethrough. If you try to peel the cover together with the roof tiles from the bottom plate by blowing it inside the side piece of the cover, the upper edge 15 ′ of the upper engaging piece of the upper cover is bent inward of the lower cover. It comes into contact with the lower surface of the piece 14 and, in combination with the above-mentioned improved mounting strength, sufficiently withstands wind force. Therefore, the roof tiles and the cover are not blown off by the strong wind.

Furthermore, the lower edge of the side piece 14 slopes uphill with respect to the upper edge and its downward length decreases towards the rear. The rear portion of the front cover including the side piece 12, the upper surface piece 11, and the inward bending piece 14 is provided between the lower surface of the folded fitting portion of the rear cover and the upper edge portion 15 ′ of the upward engaging piece. Since it is attached to the side of the roof tile of each step through the gap 16 on the side of the shingles, it is sufficient to mold the shroud cover to be attached to any of the steps of the roof tiles to the same size, which results in complicated manufacturing, storage, and construction. Is eliminated.
In addition, the appearance of Keraba under construction is very attractive.

Further, if the wind blows into the side piece 11 of the cover, the side piece 12 is bent by the wind force, and the upper edge portion of the upward engaging portion 15 provided on the inward bending piece 14 connected to this side piece 12. 15 ',
The upward projecting portion 19 adjacent to this engages with the lower surface of the inwardly folded back piece of the lower cover and the inner edge thereof, so that the mounting strength is further improved.
