Abstract

PROBLEM TO BE SOLVED: To make rainwater, which infiltrates into a valley decorative sheet metal constructed in the valley of a roof, flow smoothly to a valley gutter.SOLUTION: A valley decorative sheet metal 1 covers a cut surface 26 of a roof material 25 constructed in a valley part 20 of a roof configured by crossing two sloped roof surfaces. When mounting the valley decorative sheet metal 1 on the valley part, an undersurface located below the roof material 25 is not parallel to a valley gutter and slanted downslope toward a valley core, and thus water does not turn into the rear side of the roof material and a high waterproof performance can be exhibited without using a sealant and the like. Fixation of the valley decorative sheet metal 1 to the valley part 20 is facilitated by providing a fixing plane in parallel with a sheathing surface, and rainwater is made to flow down to the valley gutter by providing a drain hole in the undersurface and/or a decorative surface 11 of the valley decorative sheet metal 1.

Description

  The present invention relates to a decorative sheet metal that covers a cut surface of a roof material constructed in a valley of a roof, and more particularly relates to a valley decorative sheet metal having both design and waterproof performance, and a roof structure using the same. It is.

  When constructing a valley of a building having a valley on the roof, since most of the manufactured roofing material is rectangular, the valley is configured obliquely with respect to the eaves and the ridge. If you can pay without processing, there is almost nothing. For this reason, there are also dedicated objects such as so-called valley roof tiles that are pre-matched to the shape of the valley, but because the shape is somewhat complicated, mass production is difficult, the amount used is small, and general roofing materials Due to issues such as the need for separate treatment, the costs inevitably increased, and there were not many examples of adoption.

  Therefore, in most cases, a roof material facing the valley core is cut in part, and the cut surface is often exposed. In recent years, since the completeness of the roof finish is often required, the design of the roof has been improved by applying the cut surface to the cut surface with paint of the same color as the roofing material, or by a member that wraps the cut surface. Many measures have been taken to make it happen.

  As an example of a member that wraps a cut surface of a roof material, there is an invention described in Patent Document 1 as shown in FIG. According to this invention, the state in which the cover body floats upward from the upper surface of the valley plate so that the water flowing on the roof material flows from the gap 51 between the cover body 5 and the valley plate 50 to the center of the valley portion on the valley plate. Moreover, it is set as the structure by which the clearance gap used as the channel | path of water is formed between the lower end of the end surface cover part 52 of a cover body, and the trough board upper surface.

  The invention of Patent Document 1 improves the design of the valley and prevents the water flowing on the roofing material from being blocked by the cover body. Therefore, since it can be made to flow smoothly to the trough center side of a trough, water leakage can be prevented.

  Further, as shown in FIG. 16, according to the invention described in Patent Document 2, the bottom surface portion 71, the tile end covering portion 72, the top surface portion 73, the eaves surface portion, and the bottom surface portion provided to wrap the roofing material are provided. A pair of roof tile accommodating portions 70 each having a hole portion 75, a valley covering portion 77, and two longitudinal sides of the valley covering portion extending inward of the V-shaped cross section. There is a roof trough finishing tool 70 composed of a side surface portion 78a and a trough portion 76 having a second side surface portion 78b.

  According to the invention of Patent Document 2, the edge of the tile cut along the valley is covered with the tile storage portion, and the side of the tile is also covered with the eaves surface, so that the skilled worker does not neatly align the cut surface of the valley In addition, it is possible to finish the valley with a good appearance in an easy and short work.

  However, the above invention still has room for improvement. In other words, the decorative member of the valley below the roofing material is such that the lower part of the bottom of the roofing material is parallel to the field plate, so that the water that has flowed through the surface of the roofing material will cut the cut surface of the roofing material. When flowing down to the bottom of the roofing material, the lower part of the decorative member has only a gradient parallel to the roofing material, so that it tends to reach the general roof surface (flat part of the roof) by going back to the lower part. In particular, in a building with a gentle roof slope, the inclined surface constituting the valley also becomes loose, so that it becomes difficult for water to reach the valley smoothly and easily go back to the general roof surface side.

  Moreover, in patent document 1 invention, since the cover body was fixed with the hanging member, there was a problem that a hanging member was required separately, variation in construction occurred, and the construction was troublesome. . Further, in Patent Document 2, in consideration of the above-described aspect, a configuration in which the space between the vicinity of the ridge side end of the decorative member and the roof material is filled with the sealing material 79 is employed. The position and amount of construction may vary depending on the operator, cracks may occur due to deterioration of the sealing material over time, and the construction of the sealing material 79 may be forgotten. There wasn't.

  In view of the above, in the present invention, as a result of intensive studies on the shape of the valley decorative sheet metal to be applied to the valley, the bottom surface of the valley decorative sheet metal is inclined so that rainwater that has entered the valley decorative sheet metal can be smoothly removed. I found that it would be better to flow to the valley.

  In order to solve the above-mentioned problem, in the present invention, a valley decorative sheet metal that covers a cut surface of a roof material constructed on a trough of a roof constructed by intersecting two sloped roof surfaces, the trough At the time of attachment to the roof, a configuration is adopted in which the lower surface located below the roof material is non-parallel to the trough and has a downward slope toward the trough core side.

  By adopting the above configuration, when rainwater that has fallen on the roof material flows down and hits the valley decorative sheet metal, the surface of the roof material facing the valley, the cut surface or the decorative surface of the roof material, It reaches the lower surface of the valley decorative sheet metal through the rear surface edge of the roofing material. Since the lower surface is provided with a downward slope toward the valley core, it is possible to suppress the momentum when rainwater attempts to reach the flat portion of the roof by going back the lower surface.

  Moreover, in order to demonstrate said invention more effectively, a fixed surface of a trough decorative sheet metal is not the same surface as the said lower surface, By adopting the structure provided in parallel with the field ground, a field plate Or, since the fixing portion is parallel to the discarded pier for fixing the valley, it is easy to fix to the base material such as the field board or the discarded pier. In addition, by providing a drain hole on the lower surface and / or the decorative surface of the valley decorative sheet metal, at least part of the rainwater flowing down the cut surface or the decorative surface of the roof material reaches the lower surface. It is allowed to flow smoothly down to the valley through a half-direct water drainage hole. Since the valley portion is also a location where rainwater on the roof surface constituting it concentrates, rainwater that has been concentrated and flowing down can be guided to the valley at any time, so that the waterproof performance can be improved.

  And the roof of the roof which used the valley part sheet metal constructed from the valley wall constructed in the valley part of the roof, the valley part decorative sheet metal as described above, and the roof material whose cut surface is covered by the valley part decorative sheet metal By providing the valley structure, it is possible to provide a roof structure that does not allow rainwater or the like to enter indoors even in a building having a valley on the roof.

  According to the present invention, by covering the cut surface of the roof material facing the valley portion of the roof with the valley decorative sheet metal, even if the cutting accuracy of the cut surface of the roof material is not high, the cut surface is also painted or the like Not only can the design be improved without repairs, but the rainwater concentrated in the valleys can flow smoothly down the valley, and rainwater can enter the roof from the bottom of the roofing material. The effect of being able to be suppressed is exhibited.

  Examples of the present invention will be described in detail below.

  First, as shown in FIGS. 1 to 6, the basic configuration of the valley decorative sheet metal 1 of the present invention is the upper surface 10 that covers the roof material 25 from above in a cross-sectional view, and the roof material 25 from the end of the upper surface on the valley core side. A lower surface 12 provided with an upward slope from the lower end of the decorative surface toward the rear surface of the roof material, so as to face the cut surface 26 of The lower surface is a non-coplanar surface and includes a fixed surface 14 having a surface substantially parallel to the base plate or roof material 25. In addition, the bent portion 15 constituted by the decorative surface and the lower surface is configured so that the storage space S side has an acute angle, and rainwater flowing down the surface of the roofing material 25 can smoothly flow into the bent portion. It has a drain hole 16 that can be drained into the water. In addition, the said lower surface and the said fixed surface may be comprised continuously, and may be connected via the connection surface 13, and an optimal means is employ | adopted suitably according to the specification of the trough part of a roof. . In addition, the plate | board thickness of the said valley part decorative sheet metal makes 0.3 mm-0.5 mm as an example, and the versatile thickness of about 0.35 mm-0.4 mm is especially suitable.

  The valley decorative sheet metal 1 according to the present invention is formed so as to be integrated from the upper surface 10 to the fixed surface 14, and has a substantially “7” -shaped cross section or an inverted “7” -shaped cross-section in a state of being applied to the valley. It has a shape like a warp. The storage space S constituted by the upper surface 10, the decorative surface 11, and the lower surface 12 is shaped to wrap around the cut surface 26 of the roof material 25. In addition, since the material of a valley part decorative sheet metal is directly exposed to a roof surface, highly durable things, such as a Galvalume steel plate, are selected.

  The upper surface 10 of the valley decorative sheet metal 1 extends to the opposite side of the valley core 21 with respect to the decorative surface 11, and is provided substantially parallel to the roof material 25. Moreover, the folding | wrapping is provided in the roof material side of an upper surface so that the edge part of sheet metal may comprise a substantially U shape to a valley core side and a back side. The length of the upper surface 10 is a cut surface having a variation in cutting accuracy from the reference cutting position of the roof material facing the valley processed at the site (the position indicating the range of the roof where the roof material is constructed). It is desirable to be able to cover all.

  The decorative surface 11 of the valley decorative sheet metal 1 is suspended toward the valley wall 3 so as to be substantially perpendicular to the end opposite to the folded back of the upper surface 10. The decorative surface 11 is opposed to the cut surface 26 of the roofing material 25 facing the valley 20, and the decorative surface 11 conceals the cut surface 26 from the eaves side viewpoint to improve the design. The height of the decorative surface 11 is generally larger than the thickness of the roofing material 25 facing the valley 20 (the total thickness when two or more roofing materials overlap), and at least the roofing material 25. In addition to the above thickness, the gap between the upper surface 10 and the roof material 25 and the gap between the roof material 25 and the lower surface 12 (gradient relative to the direction perpendicular to the lower surface) are greater. Therefore, when the roof material is a thick material such as a ceramic tile, the length of the decorative surface is increased in the vertical direction according to the thickness.

  The lower surface 12 of the valley decorative sheet metal 1 extends so as to be positioned below the roof material 25 with a slightly acute angle (upward gradient toward the roof material side) from the lower end of the decorative surface 11. The lower surface 12 is formed to be longer than the upper surface 10 so that when the water that has fallen on the roofing material 25 flows into the valley decorative sheet metal 1, the entire amount thereof flows down to the trough 20. As shown in FIG. 7a, the lower surface 12 is already provided with a downward slope toward the valley core 21 with respect to the base plate 22 so that it is difficult for water to further flow down the lower surface 12 to the flat portion of the roof. It is good also as a kind of water return shape by providing the protrusion 17 which protruded upwards with respect to the lower surface in the longitudinal direction at one or several strips, intermittently or continuously. In addition, the gradient of the lower surface 12 extends from the bent portion 15 toward the ridge side of the lower surface 12 (in the present invention, the ridge side refers to the direction opposite to the valley core with respect to the decorative surface). May not have the same gradient, for example, the gradient may be changed stepwise as shown in FIG. 7b, or may be curved upward from the lower end of the decorative surface as shown in FIG. 7c. Moreover, it is good also as a structure which provides a gradient or the wall surface 18 in the middle of the lower surface provided at right angles to the decorative surface (for example, FIG. 7d. In this case, the lower surface and the fixed surface may be parallel). obtain). The valley decorative sheet metal of the present invention appropriately changes the distance between the upper surface and the lower surface and the length of the lower surface according to the thickness of the roofing material to be constructed, the covering range of the roofing material to the trough, etc. Is possible.

  As shown in FIGS. 2, 4, 5, etc., a water drain hole 16 is provided in the bent portion 15 constituted by the decorative surface 11 and the lower surface 12. The drain hole 16 has a round hole or a square hole continuously provided in the longitudinal direction with a predetermined width and length (height) on the decorative surface 11 and / or the lower surface 12, particularly on the bent portion side. . The size of the drain hole 16 may be any size as long as it flows without a delay even if there is a certain amount of water. As an example, the width (longitudinal side) is preferably 3 mm to 10 mm, particularly about 5 mm. (Short direction side) should be 6 mm to 25 mm, especially about 10 mm to 20 mm, of which 3 mm to 7 mm is provided on the decorative surface 11 side, and 5 mm to 13 mm is provided across the bent portion on the lower surface side. Is preferred. Further, the drain hole 16 may be provided continuously in the longitudinal direction of the valley decorative sheet metal 1, or the bent portion 15 may be cut long in the longitudinal direction.

  The fixing part 14 of the valley decorative sheet metal 1 is not on the same plane as the lower surface 12, and is provided so as to be substantially parallel to the field plate 22. As an example, when the fixing portion 14 is fixed to the base plate 22, the fixing surface 14 is provided below the ridge side end portion via the connection surface 13 from the ridge side end portion of the lower surface 12. As another example, when the fixing portion 14 is fixed to a scraper 24 for fixing a valley roof, which is particularly seen in a thick roof material, the connection surface 13 is not necessary and the ridge side of the lower surface 12 is used. You may form continuously from an edge part {(c) of FIG. 12} as an example. When the valley decorative sheet metal 1 is fixed to the valley 20 in any example, the fixing portion 14 is nailed from above and subjected to a caulking process or the like for preventing rainwater or the like from entering the nail. And fix.

  The basic configuration of the valley decorative sheet metal 1 of the present invention has been described above, but other configurations will be described in detail below.

  The valley decorative sheet metal 1 of the present invention can be applied to the entire length of the valley, but the vicinity of the eaves edge E cannot be accommodated in the usual shape because of the influence of interference with the roofing material 25 to be applied later. There is. In addition, it is difficult to maintain high designability as it is with the valley 20 and the eaves edge E. Therefore, as shown in FIG. 8 a, the eaves end E of the roofing material 25 facing the valley 20 (the head material of the roofing material) is appropriately cut while leaving the upper surface 10 of the valley decorative sheet metal 1, and the upper surface 10 is The eaves-side decorative surface 19 is formed by bending so as to hang down in accordance with the eaves edge E, and covers the portion of the roofing material 25 where the cut surface 26 intersects the portion where the eaves edge E is found. As a result, as shown in FIGS. 8b and 8c, the intersecting portions described above can be finished without a sense of incongruity, and high designability is ensured. FIG. 8b shows a state where a thin roof material such as a metal tile or a decorative slate is accommodated, and FIG. 8c shows a state where a thick roof material such as a cement tile or a clay tile is finished.

  Moreover, in this invention, it is good also as a structure which makes the material of the valley part decorative sheet metal 1 (especially the upper surface 10 and the decorative surface 11) the same quality as a roofing material. The term “same quality” as used herein refers to the same material, as well as the same roof surface condition (such as a grainy pattern or stone sprayed state), or the same or similar color. To align. By adopting this configuration, the roof material 25 and the valley decorative sheet metal 1 have the same appearance, and it is possible to provide design as if the roof material 25 continues to the cut surface 26 facing the valley 20.

  In the valley structure of the roof using the valley decorative sheet metal 1 of the present invention, the valley facing 3 itself and the valley facing 3 constructed on the valley core 21 and the surface facing the valley 20 other than the valley decorative sheet metal 1 are cut. The roofing material 25 is composed of roofing materials and roofs attached thereto. As shown in FIG. 9 a, the trough 3 is generally wide and long in the trough direction (only the cross section of the trough is shown in the figure), and the trough core 21. Is provided with an inclined surface 30 that roughly matches the angle of the two roof surfaces that constitute the trough. Furthermore, the folding | wrapping extended toward the valley core side above the edge part of an inclined surface is provided. In this case, the trough 3 is fixed to the base plate 22 via the hanging element 33 in the folded state. In the case of a thick roof material or the like, the trough 3 is often fixed to a scraper 24 constructed in parallel with the trough core as shown in FIG. A rising surface 31 extending upward at right angles and a trough fixing surface 32 extending in a substantially right angle direction from the upper end of the rising surface to the side opposite to the trough core are provided. It is fixed by nailing or the like from the surface 32 toward the scraper 24 (FIG. 12b for reference). Here, the roofing material 25 that comes out in the present invention is used for general buildings such as metal tiles, cement tiles, and ceramic tiles. Since the amount of exposure increases, the effect of improving the designability by the valley decorative sheet metal 1 of the present invention is great.

[Example 1]
Hereinafter, construction of the valley part decorative sheet metal 1 of the present invention will be described in detail. In this embodiment, as an example of a thin roof material, an example in which metal tiles are employed is illustrated.

  After the upper building, a roofing 23 is constructed in the valley 20 of the roof 2 constructed by constructing the base plate 22 (a in FIG. 10). Subsequently, the trough 3 is constructed around the trough core 21. At this time, when only the both ends of the valley trough 3 are folded back to the valley core 21 side, the hanging bar 33 is used to fix it to the base plate 22 at a predetermined location. In addition, the surface of the trough 3 is inked so that it becomes a standard of the construction position of the trough decorative sheet metal 1 (b in FIG. 10). Following the construction of the trough 3, the trough decorative sheet metal 1 of the present invention is constructed on the base plate 22. The fixing surface 14 is positioned so as to be farther from the valley core 21 than the trough 20 and is fixed by nailing from the upper part of the fixing surface 14 to the base plate 22 (c in FIG. 10). At this time, a caulking material or the like may be applied to the nailing portion in order to ensure waterproofness.

  After the construction up to Tanibe decorative sheet metal 1, the metal tile 25 is constructed from the eaves side. The metal roof tiles on the valley 20 are cut so as to meet the reference with a position separated from the valley core by a predetermined distance as a reference. At this time, the cut surface 26 of the metal tile 25 applied to the valley 20 is covered with the storage space S of the valley decorative sheet metal 1 and is not confirmed in appearance from the eaves side, so there is no need to ask the accuracy of the cut surface 26. Some cut surfaces 26 may be stepped or wavy. The metal roof tile 25 cut along the valley 20 is accommodated by sliding the cut surface 26 from the flat side of the roof toward the valley so that the cut surface 26 can be stored in the storage space S of the valley decorative sheet metal 1 (FIG. 11 d).

  These steps are repeated until the building, and all the metal roof tile 25 facing the valley 20 is cut at a predetermined location, the cut surface 26 is stored in the storage space S, and the metal roof 25 facing the valley 20 is fixed to the base plate 22. The construction is completed (e in FIG. 11). In the construction as described above, the cut metal tile 25 remains exposed at the portion where the eaves end E and the valley 20 intersect, and the cut surface becomes conspicuous in the appearance from the eaves side. In order to eliminate this, the eaves end E of the valley decorative sheet metal 1 is cut as shown in FIG. 8 to cover a part of the metal roof tile 25 at the eaves end E. The eaves side decorative surface 19 is folded and formed. This operation may be performed at any timing before, after, or after the construction of the metal roof tile 25.

  By these constructions, since the cut surface 26 of the metal roof tile 25 is hidden by the decorative surface 11 (upper surface 10), the trough portion 20 can provide a storage structure with a good design of the trough portion 20. In this structure, the water that has fallen on the metal tile 25 flows down the surface of the metal tile 25, enters the storage space S through the gap between the metal tile 25 and the upper surface 10, and is inside the decorative surface 11 (metal tile side). Alternatively, it reaches the lower surface 12 via the cut surface 26 of the metal roof tile 25. Since the lower surface 12 has a steeper slope than the valley 20 toward the valley core 21, the lower surface 12 does not reach the flat portion side of the roof by going back from the lower surface 12. The water is immediately discharged from the hole 16 to the trough 3 and flows down to the eaves (not shown) via the trough 3. Since the bottom surface 12 of the valley decorative sheet metal 1 is not parallel to the back surface of the metal tile 25 and there is a certain gap, water rises due to capillary action or the like from the most valley core side of the metal tile back surface. Never come. In addition, since the water falling on the surface of the metal tile 25 passes through the valley decorative sheet metal 1, the momentum of the water falling from the metal tile 25 to the valley tile 3 can be suppressed as compared with the case of flowing directly to the valley tile 3. Therefore, for example, in the case of a valley plate 3 made of a copper plate or the like, it is difficult to cause corrosion of the surface coating due to the impact of water.

[Example 2]
In this example, the construction of a ceramic roof tile will be described in detail as an example of a relatively thick roofing material.

  After the roofing construction, the tiles (not shown) are continuously placed on the flat part, and the troughs 20 are disposed on the roofing 23 at intervals corresponding to the width of the trough 3 in parallel with the valley core 21. Construction is performed (a in FIG. 12). In the present embodiment, compared to the above-described embodiment, it is necessary to construct the tile rail and the discard rail 24 due to the difference in the construction method of the ceramic tile. The trough 3 is fitted between the scraping bars 24, and the trough fixing part 32 is nail fixed to the scraping bar 24. The trough 3 in the present embodiment is provided with a rising surface 31 and a trough fixing surface 32 provided vertically above the inclined surface 30 at both ends in the width direction as described above and illustrated in FIG. It is integrally formed so as to wrap the crosspiece 24 (b in FIG. 12).

  If fixing of the trough 3 is completed, the trough decorative sheet metal 1 of the present invention is subsequently applied to the trough 20. The fixing surface 14 of the valley decorative sheet metal 1 is aligned with the position of the scraper 24, and is fixed to the scraper 24 with a nail or the like from above the valley anchoring surface 32 (c in FIG. 12). At this time, the valley decorative sheet metal 1 is not fixed to the scraper 24, but the shape is changed so that the valley fixing surface 32 comes to the flat part of the roof, and is driven into the base plate 22 from the flat part of the roof with a nail or the like. It may be fixed. When the valley decorative sheet metal 1 is constructed, the ceramic tile 25 facing the valley 20 is cut in accordance with the position of the decorative surface 11, and is slid and fixed so as to be stored in the storage space S (d in FIG. 13).

  By repeating these steps up to the building, all the ceramic tiles 25 facing the valley 20 are cut at a predetermined location, the cut surface 26 is stored in the storage space S, and the ceramic tile 25 facing the valley 20 is fixed to the roof rail. The construction is completed (e in FIG. 13).

  With this configuration, the cut surface 26 of the earthenware tile 25 cut along the valley core 21 is exposed, and the cut surface 26 is not inferior to the color of the surface of the earthenware tile 25. Therefore, the problem that it is necessary to apply paint can be solved. Even if the cutting accuracy of the cut surface 26 is not high, it is covered with the upper surface 10 or the decorative surface 11 of the valley decorative sheet metal 1, so that the workability is improved and the design of the roof having the valley 20 is improved. The effect of improving is demonstrated. Furthermore, small pieces to be constructed in valleys (here, small ceramic tiles constructed in valleys and generated due to cutting conditions such as the edges of ceramic tiles) that are likely to occur in the case of ceramic tiles 25 due to storms, etc. It also has the effect of “suppressing” from above so as not to scatter.

  In addition to the above embodiments, the valley decorative sheet metal of the present invention is not limited to the roof of a newly built building, but a thin roof material such as a slate tile or a metal tile as shown in FIG. It is possible to construct the existing roof B on the roof of a building in which the roof material 25 is newly constructed from above the roof material (the construction is also possible for the so-called cover method).

  In addition, although the trough decorative sheet metal 1 and the roof structure using the same according to the present invention have been specifically described, the present invention is not limited to the above-described preferred examples, and in a range not departing from the fundamental technical idea thereof. It can be changed as appropriate. For example, the surface layer of the valley decorative sheet metal may be coated with a ceramic coating, the material may be changed to a highly durable resin material instead of metal, or the material may be made of ceramic if it is thin and high in strength. Further, the valley decorative sheet metal does not necessarily have to be integrally formed. For example, a part divided by a bent part may be integrated by riveting or the like. It is good also as a structure which makes a concave structure the side which has, and can be integrated with the said uneven structure. Furthermore, the conventional technology of FIG. 15 is applied, and even with the same valley-shaped decorative sheet metal 1, the upper surface 10 and the decorative surface 11 that are easily affected by the outdoor environment such as ultraviolet rays and dust are separated from the lower surface 12 and the shape is slightly changed. By adopting a structure that can be combined, it is possible to replace only the part that is severely affected and has an influence on the appearance, so that maintenance is facilitated. With this structure, even if the space between the top surface and the roofing material is clogged with branches and leaves and the appearance looks bad, it is easy to cope with it.

  INDUSTRIAL APPLICABILITY The present invention can be widely used as one of members for covering a roof material to be constructed in a trough portion of a roof and further as a roof auxiliary material for treating an end portion of the roof material.
