Description

[Technical field]

[0001] The present invention relates to a covering material and an eaves structure that can prevent clogging of eaves gutters caused by coniferous trees and small dead leaves that are blown away by strong winds, etc. [Background technology]

[0002] On the roofs of buildings, various gutters such as eaves gutters and interior gutters are installed as channels for carrying rainwater, but if fallen leaves or dead trees get mixed in with the rainwater, the gutters will become clogged. To prevent this, covering materials with inlets that prevent fallen leaves from entering the surfaces of the gutters are often used, or covering materials with a mesh pattern are often installed on the entire surface. Patent Document 1 proposes a gutter structure in which multiple gutter covers, both ends of which are folded down, are installed in parallel with gaps in the flow direction, and rainwater flowing down is introduced into the gutter through the "gaps" between adjacent gutter covers. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-156151 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] However, in the structure of Patent Document 1, vegetation such as fallen leaves and dead trees, as well as soil and sand, are mixed with the rainwater flowing down in the direction of flow, so coniferous leaves and small dead leaves may enter (fall into) the gutter through the "gaps" in the gutter cover, or if there is a large amount of fallen leaves flowing along with the rain (large accumulation on the roof), they may block the gaps or become trapped. In addition, fallen leaves that get into the gutters may accumulate inside the gutters or at the outlet of the downspout depending on the length of the gutter itself, the position of the downspout, and other installation conditions, as well as the amount of rainfall, which may lead to a decrease in drainage performance or overflow. Furthermore, fallen leaves that get caught in the gutter cover act as a dam, causing more and more leaves to gradually pile up, which reduces the drainage function from the gutter cover to the gutter.In addition, dead leaves and other debris accumulate on the gutter cover, which damages the appearance of the area.

[0005] Therefore, an object of the present invention is to propose a covering material and an eaves structure that can prevent clogging of eaves gutters caused by coniferous trees and small dead leaves that are blown away by strong winds, etc. [Means for solving the problem]

[0006] In view of the above, it has been discovered that by providing a drainage hole on the downstream side of the flow gradient of the roof surface through which rainwater is guided to the rear surface, and by adopting a structure in which a portion (protruding portion) protruding to the front surface side is provided on the upstream side of the drainage hole, it is possible to stop needle-leaving trees and small dead leaves, etc., which may mix with the rainwater guided to the rear surface from the drainage hole and cause clogging. The present invention also proposes a covering material to which the above-mentioned structure is applied, and an eaves structure in which the above-mentioned structure is applied to a roof surface including the covering material.

[0007] The present invention relates to a covering material that is placed above an eaves gutter and is characterized by having a drainage hole through which rainwater is guided to the back side and a protrusion toward the front side on the above-water side of the drainage hole.

[0008] The present invention also proposes an eaves structure in which a covering material is placed above the eaves gutter at the eaves of the roof surface, the covering material having a drainage hole in its panel portion through which rainwater is guided to the back side, and the covering material and / or the roof surface having a protrusion toward the front side on the above-water side of the drainage hole. Effect of the Invention

[0009] The covering material of the present invention is positioned above the eaves gutter and has a drainage hole that directs rainwater to the back side, and a protrusion toward the front side on the above-water side of the drainage hole. Therefore, the protrusion on the above-water side can prevent the progression of coniferous trees such as Japanese larch and small dead leaves, which are prone to clogging the gutter, due to the roof slope, and other rainwater can be guided into the eaves gutter through the drainage hole on the below-water side of the protrusion and drained. This cover material can be provided in two forms: one in which a protrusion is formed on the panel portion itself, and one in which a band-shaped face piece with a protrusion formed thereon is fixed (integrated) to the panel portion of the main body. In either form, the protrusion can be easily formed, so the effort and cost involved can be kept low.

[0010] In addition, the eaves structure of the present invention has a covering material placed above the eaves gutter at the eaves of the roof surface, and the covering material has a drainage hole in its panel portion that directs rainwater to the back side, and a protrusion toward the front side is provided on the above-water side of the drainage hole, so that the structure has a protrusion formed on the roof surface etc. including the covering material, but the progression of coniferous trees such as Japanese larch and small dead leaves, which are prone to clogging the gutter, due to the roof slope can be prevented by the protrusion on the roof surface etc. including the covering material, and other rainwater can be guided into the eaves gutter through the drainage hole in the roof surface etc. on the below-water side of the protrusion and drained. This eaves structure can be implemented in two ways: one in which a protrusion is formed on the roof material that forms the roof surface or on the cover material itself, and one in which a band-shaped surface body with a protrusion formed thereon is fixed (integrated) to the roof surface.In either embodiment, the protrusion can be easily formed, so the effort and cost involved can be kept low.

[0012] The covering material of the present invention is characterized in that it is positioned above the eaves gutter, has a drainage hole through which rainwater is guided to the back side, and has a protrusion toward the front side on the above-water side of the drainage hole. The present invention also proposes an eaves structure in which a covering material is placed above the eaves gutter at the eaves of the roof surface, wherein the covering material has a drainage hole in its panel portion through which rainwater is guided to the back side, and the covering material and / or the roof surface have a protrusion toward the front side on the above-water side of the drainage hole.

[0013] As described above, the present invention adopts a structure in which a drainage hole is provided on the downstream side of the flow gradient of the roof surface to guide rainwater to the back side, and a portion (protrusion) is provided on the above-water side of the drainage hole that protrudes to the front side, and proposes a covering material (first specification) to which the above-mentioned structure is applied, and an eaves structure in which the above-mentioned structure is applied to a roof surface including a covering material (second specification). This first specification cover material comes in two forms: one in which a protrusion is formed on the panel portion itself, and one in which a band-shaped face piece with a protrusion formed thereon is fixed (integrated) to the panel portion of the main body. However, because the protrusion can be easily formed, effort and costs can be kept low in either form. That is, the first specification cover material has a protrusion as an essential component, whereas the second specification cover material does not necessarily have to have a protrusion.

[0014] The drainage hole is a portion through which rainwater is guided from the flat surface plate provided in both the first and second specification covering materials to the back surface side, and may be formed only with a plurality of perforations (openings) penetrating the surface plate, or may be formed with a guide portion that slopes continuously from the front surface side to the back surface side and an opening portion formed on the downstream side of the guide portion. Note that the guide portion in the latter specification is at least partially arc-shaped with its center or center of gravity located on the back surface side, and rainwater is reliably guided from this guide portion in the depth direction to fall into the eaves gutter. It is desirable that a plurality of these drainage holes are provided in each of the flow direction and the width direction, and that they are arranged in a phased manner in the flow direction.

[0015] The protrusion is a part formed on the first specification cover material (main body or band-shaped face body) and protrudes from the panel portion toward the surface side. There are no limitations on the shape or number of the protruding parts, and they may be, for example, needle-shaped or small piece-shaped, and may be selected depending on various conditions such as the location of the building and the shape of the roof. The protruding portion having the small protruding portion is easily formed, for example, by making a cut in a predetermined shape and folding up the inner portion from the back side to the front side, as in the illustrated embodiment described later. In this specification, a through hole is formed by folding up, so if the protruding portion is formed in the main body itself, rainwater can be guided from this through hole to the back side.

[0016] Although no other configuration is specified for this cover material, it is desirable for it to have a configuration for being placed above the eaves gutter, and such a configuration may include a configuration in which an attachment portion is provided at at least one of the above-water end or below-water end, and it may be possible to provide an attachment portion at each of the above-water end and below-water end of the cover material, as in the illustrated example described below. The attachment part to be provided on the underwater side is preferably provided with a U-shaped engagement part that engages with the upper end of the side surface on the eaves side of the eaves gutter, etc., as shown in the figure. In this case, this attachment serves to hold the eaves side of the eaves gutter up. The mounting part on the water side is preferably fixed to the eaves arabesque etc. fixed to the exterior base with screws as shown in the figure. In this case, the weight of the eaves gutter can be borne by the eaves arabesque on the exterior base by this mounting.

[0017] Furthermore, the panel portion of this covering material may be one-plane, i.e., linear when viewed from the side, or it may have two connected planes, i.e., L-shaped when viewed from the side. In the latter case, the surface side may have a valley-shaped bottom, and the valley-shaped bottom may be provided with an eaves-side drainage groove having a concave cross-section. In addition, when molding into an L-shape when viewed from the side, there is an embodiment in which the cover part is molded into a downward sloping surface toward the eaves, as in the illustrated example described below, and the upper surface of the below-water mounting part (C-shaped engagement part) is molded into an upward sloping surface toward the eaves, and the boundary between these forms the valley-shaped bottom.

[0018] In this way, when an eaves-side drain groove with a concave cross section that continues in the length direction is provided and the eaves-side drain groove is formed in the valley-shaped bottom, rainwater can be reliably collected on the front side of the eaves-side drain groove, and even if some rainwater cannot fall to the back side (eaves gutter) through the drainage holes, etc., it can be reliably collected and drained in the length direction. Furthermore, rainwater that does not fall through the drainage holes but flows down the back side of the covering material can be reliably collected on the back side of the eaves-side drain groove and falls to the back side (eaves gutter).

[0019] When the drainage hole is formed in a guide portion that slopes continuously from the front side to the back side of the cover material and on the water side of the guide portion, the molding process of this drainage hole is not particularly limited, but for example, the desired drainage hole can be formed by combining (simultaneously) slit processing in the width dimension and press processing with this as the lower end.

[0020] In addition, when the protrusion is formed into a small piece by cutting a predetermined shape and folding the inner part from the back side to the front side, the molding process of the protrusion is not particularly limited, but for example, a protrusion in the shape of a triangle can be formed by cutting a L-shape and folding the inner part up to the front side. As described above, in this specification, a through hole is formed by folding up, so if the protrusion is formed in the main body itself, rainwater can be guided from the through hole to the back side. In addition, when a protrusion is provided on the roof surface (various exterior materials), a protrusion in the shape of a protrusion by bending or pressing, or a mode in which the strip-shaped surface material is integrated with the surface plate of the exterior material can be mentioned. Furthermore, depending on the location of the building, etc., a protrusion may be provided on both the roof surface and the cover material.

[0021] This cover material is made of metal, synthetic resin, or other material, but is not particularly limited as long as it is a material that can be processed as described above. For example, materials that are also used as horizontal exterior materials (roofing materials), typically known metal materials such as surface-decorated steel plates, laminated steel plates, plated steel plates, stainless steel plates, aluminum alloy plates, titanium alloy plates, copper plates, etc., having a thickness of approximately 0.4 to 1.6 mm, can be used.

[0022] In addition, when the protrusions are formed on the cover material itself (main body), it is not necessary to use the band-shaped surface body, but a band-shaped surface body equipped with protrusions may be fixed (integrated) to the panel portion of the main body so that multiple stages of protrusions are formed in the flow direction, or it may be attached to the exterior surface (various exterior materials) above the water of the second specification cover material.

[0023] In the eaves structure of the present invention, a drainage hole is provided in the first or second specification covering material, and a protrusion is provided above the waterline of the drainage hole, so that the protrusion is formed on the exterior surface. That is, as described above, a protrusion is not necessarily formed in the second specification covering material, so that a protrusion is formed on the various exterior materials that make up the exterior surface. As described above, the molding process of this protrusion is easy, and therefore it can be easily applied to exterior materials (forming a protrusion on the face plate of the exterior material); however, by using a strip having the aforementioned protrusion formed thereon and integrating this strip with the surface of at least one exterior material in one or more places, the present invention can also be easily applied to the renovation of an existing roof. EXAMPLES

[0024] Figures 1(a) and 2 show an eaves structure using a covering material 1 according to a first embodiment of the present invention. The covering material 1 is configured by integrating a main body 2 having a plurality of drainage holes 211 through which rainwater is guided to the back side and a band-shaped surface body 3 having a plurality of protrusions 31 protruding to the front side, as shown enlarged in Figures 1(b) and (c), in a superimposed manner, and is attached at an angle so as to cover the open upper part of the eaves gutter 4. This cover material 1 is configured such that the protrusion 31 of the band-shaped surface body 3 is positioned on the above-water side of the drainage hole 211 of the main body 2, and the above-water side protrusion 31 prevents the progression of coniferous trees and small dead leaves, which are prone to clogging the gutter, due to the roof slope, and rainwater that has been removed can be guided into the eaves gutter 4 through the below-water side drainage hole 211 and drained.

[0025] The band-shaped surface body 3 used in this Example 1 is a rectangular metal or synthetic resin surface material that is short in the flow direction and long in the left-right direction, and the protrusions 31, which are approximately triangular upright pieces protruding from the front side, are provided in two rows in the flow direction and in multiple stages in the left-right direction, and are arranged in a phased manner in the flow direction. In detail, this protrusion 31 is cut in a L-shape and its inner portion is folded up from the back side to the front side, thereby forming an approximately triangular through hole 310 and forming the protrusion 31 which is an approximately triangular upright piece. More specifically, the upright pieces forming the protrusion 31 are vertical along the flow direction, and the cut pieces are symmetrical with respect to a line perpendicular to the flow direction, as can be seen from the two-dot chain line in FIG. 1(c).

[0026] Drainage holes 211 are formed in the flat surface plate 21 of the main body 2 of the cover material 1. The drainage holes 211 are made up of a guide portion 211a that slopes continuously from the front side to the back side and an opening 211b that is formed on the underwater side of the guide portion 211a. A plurality of drainage holes are provided in each of the flow direction and the width direction, and are arranged in a phase pattern in the flow direction. In addition, the panel portion 21 of the main body 2 is arranged on the above-water side and has a downward sloping surface in the direction of flow, and is arranged on the below-water side and has an upward sloping surface toward the below-water end, and is L-shaped when viewed from the side, with the surface side of the connected part forming a valley-shaped bottom, and a eaves-side drainage groove 212 with a concave cross-section is formed in the valley-shaped bottom.

[0027] Further, the main body 2 is provided with mounting parts 23, 22 at its above-water end and below-water end, respectively, as a structure for covering the open upper part of the eaves gutter 4. The above-water side mounting portion 23 formed at the above-water end of the main body 2 is the portion where the above-water end 231, which is the raised tip of the contact surface 232 that is aligned with the horizontal piece of the eaves arabesque 5A fixed to the exterior base (sheathing board) 6A, is fastened with a screw (screw 2b), and is the portion where the panel portion 21 is extended toward the above-water side. In addition, the underwater side mounting portion 22 formed at the underwater end of the main body 2 is a U-shaped engagement portion whose upper surface portion forms an upwardly sloping surface toward the eaves (eaves edge), and engages with the upper end 421 of the side surface 42 on the eaves edge side of the eaves gutter 4.

[0028] In this embodiment 1, the eaves gutter 4, the upper surface of which is covered by the main body 2, is a through material having an internal space (drainage section) for draining rainwater, etc., and is formed in an approximately groove-like cross section consisting of a bottom surface 41 and two side surfaces 42, 43, and the side surface 42 on the eaves side is formed in a stepped shape consisting of three inclined surfaces and two horizontal surfaces, and its upper end 421 is an engagement receiving portion that engages in a clamping manner with the U-shaped engagement portion (underwater side mounting portion 22) of the cover material 1. The side surface 43 on the building side is a generally vertical surface with a support receiving portion 431 formed at its lower end, and the above-water end 231 is supported by a wall exterior material 8A fixed to the outside of a wall material 7B extending vertically. In the drawing, 4b is a fastener that fixes the side surface 43 to the wall material 7B, and 8b is a fastener that fixes the side surface 43 together with the wall exterior material 8A.

[0029] The eaves arabesque 5A, which fixes the above-water side mounting portion 23 of the main body 2, is configured to include a mounting portion that is attached in an engaging manner to the eaves portion of the exterior base (sheathing board) 6A, a fixed portion that fixes the above-water side mounting portion 23 of the main body 2, a holding portion that holds the eaves side molding portion of the horizontal roofing exterior material 9A that is furthest below the water, and a locking portion that locks the below-water end of the backup material 9D arranged on its back side, and is fixed integrally to the exterior base (sheathing board) 6A by fixing device 5b, so that the main body 2 fixed to the eaves arabesque 5A is also firmly attached.

[0030] The horizontally laid exterior material 9A is typically formed using known metal materials such as surface decorative steel sheets, laminated steel sheets, plated steel sheets, stainless steel sheets, aluminum alloy sheets, titanium alloy sheets, copper sheets, etc., with a thickness of about 0.4 to 1.6 mm, and has a backing material 9b attached to its back side, and a backup material 9D disposed on its back side. The overlapping portions of the backup materials 9D, 9D adjacent to each other in the flow direction and the edge of the horizontally laid exterior material 9A are fixed to the H-frame 7A with long-legged fixtures 9c.

[0031] In addition, in the building in this construction example, a sheathing board 6A made of a cemented excelsior board or the like is laid on an H-shaped structure 7A extending in the inclined direction, the backup material 9D is arranged on the upper side of the sheathing board 6A via a waterproof sheet 6b, and the horizontal exterior roofing material 9A is attached to the upper side of that.

[0032] Furthermore, a vertically extending wall material 7B is disposed at the eaves end of the H-shaped structure 7A, and a wall exterior material 8A is fixed to the outside of the wall material 7B, and the lower end (engaged portion 431) of the building-side side surface 43 of the eaves gutter 4 is supported by an L-shaped support portion 82 formed at the lower end of the vertical surface portion 81. A ceiling material 8B is disposed at the lower end of the wall material 7B.

[0033] The eaves structure using the covering material 1 of Example 1 of the present invention having such a configuration has drainage holes 211 that guide rainwater to the eaves gutter 4 on the back side, and a protrusion 31 to the front side on the above-water side of the drainage holes 211, so that the progress of coniferous trees and small dead leaves that tend to clog the gutter due to the roof slope can be prevented by the protrusion 31 on the above-water side, and rainwater other than these can be guided from the below-water side drainage holes 211 to the eaves gutter 4 and drained. Rain can also be guided to the eaves gutter 4 from the through-holes 310. Furthermore, since the covering material 1 of this Example 1 has a structure in which a band-shaped surface body 3 having a protrusion 31 formed thereon is fixed (integrated) to the panel portion 21 of the main body 2, the main body 2 may be an existing covering material, and therefore the covering material can be applied to the renovation of an existing eaves structure. Although not shown in the figure, the band-shaped surface body 3 used in the cover material 1 may be integrally attached to the face plate portion of any one or more stages of the horizontally laid exterior material 9A, and in this embodiment, the function of the aforementioned protrusion 31 can be achieved for multiple stages or more. EXAMPLES

[0034] Figure 3 shows an eaves structure using the cover material 1II of Example 2. The cover material 1II is configured by integrating a main body 2' having a plurality of drainage holes 211 through which rainwater is guided to the back side, and a band-shaped surface body 3 having a plurality of protrusions 31, which were also used in Example 1, in a superimposed state. The above-water side mounting portion 23' formed at the above-water end of the main body 2' is the same as the main body 2 in the above-mentioned Example 1, except that it is the part where the above-water end 231, which is the tip of the L-shaped contact surface 232' aligned with the horizontal and vertical pieces 51 of the eaves arabesque 5A, is fixed with a screw (screw 2b). Therefore, the same symbols are used in the drawings and the explanation is omitted.

[0035] In addition, the horizontal roofing exterior materials 9A, exterior base (roof boards) 6A, eaves arabesque 5A, H-shaped structure 7A, ceiling material 8B, etc. that form the exterior structure are similar to those in the first embodiment, so the same reference numerals are used in the drawings and explanations are omitted. However, the wall exterior material 8A', which is fixed to the outside of the wall material 7B, has a long vertical surface portion 81'.

[0036] Therefore, the eaves structure using the covering material 1II of Example 2 has the same effect as that of Example 1. In addition, since the L-shaped contact surface 232' is a stepped (step) portion, the lower portion of the step is likely to become a damming portion for coniferous trees and small dead leaves that are prevented from moving in the flow direction by the protruding portion 31. Although not shown, this is also the case in Example 2, where the band-shaped surface body 3 used in the cover material 1II may be integrally attached to the face plate portion of any one or more layers of the horizontally laid exterior material 9A, and in this embodiment, the function of the protrusion 31 described above can be achieved double or triple or more times. EXAMPLES

[0037] Figure 4(a) shows an eaves structure using a covering material 1III according to a third embodiment of the present invention. The covering material 1III is similar to the first embodiment except that it has a structure in which a main body 2 having a plurality of drainage holes 211 for directing rainwater to the back side and a band-shaped surface body 3' having a plurality of protrusions 31a, 31b protruding to the front side, as shown enlarged in Figure 4(b), are integrated in a superimposed manner. Therefore, the same symbols are used in the drawings and the explanation is omitted.

[0038] The strip-shaped surface body 3' used in this Example 3 is the same as the strip-shaped surface material 3 in Example 1 in that it is a rectangular metal or synthetic resin surface material that is short in the flow direction and long in the left-right direction, but two types of protrusions 32a, 32b, which are approximately triangular upright pieces protruding toward the front side, are separated into front and rear rows and arranged in a phase relationship in the flow direction. In detail, the two types of protrusions 32a, 32b are cut in a L-shape and the inner portion is folded up from the back side to the front side, thereby forming an approximately triangular through hole 320 and forming the protrusions 32a, 32b which are approximately triangular upright pieces. More specifically, the two types of protrusions 32a, 32b are both erected at an incline in the direction of flow. Since these protrusions 32a, 32b are inclined in both the length direction of the eaves gutter 4 and the direction of flow, they face the wind blowing against them, and are more effective at blocking coniferous trees and small dead leaves that tend to clog the gutter than the protrusion 31 in the first embodiment.

[0039] Therefore, the eaves structure using the covering material 1III of this Example 3 has the same effect as that of Example 1, that is, since the drainage hole 211 that guides rainwater to the eaves gutter 4 on the back side and the protrusions 32a, 32b toward the front side are provided on the above-water side of the drainage hole 211, the protrusions 32a, 32b on the above-water side can prevent the progression of coniferous trees and small dead leaves that are likely to clog the gutter due to the roof slope, and the rainwater excluding these can be guided from the below-water side drainage hole 211 to the eaves gutter 4 and drained. Rainwater can also be guided to the eaves gutter 4 from the through-hole 320. Although not shown, this is also the case in Example 3, where the band-shaped surface body 3' used in the cover material 1III may be integrally attached to the face plate portion of any one or more layers of the horizontally laid exterior material 9A, and in this embodiment, the functions of the aforementioned protrusions 32a, 32b can be doubled or tripled or more. EXAMPLES

[0040] Figure 5 shows an eaves structure using the cover material 1IV of Example 4. The cover material 1IV is similar to Examples 2 and 3 except that it is configured such that a main body 2' in which the L-shaped contact surface 232' used in Example 2 is a stepped (step) portion, and a band-shaped surface body 3' having multiple protrusions 32a, 32b used in Example 3 are integrated in a superimposed manner. Therefore, the same symbols are used in the drawings and the explanation is omitted.

[0041] Therefore, the eaves structure using the cover material 1IV of the fourth embodiment has the same effect as the second and third embodiments. Although not shown, the band-shaped surface body 3' used in the cover material 1IV may be attached integrally to the face plate portion of any one or more stages of the horizontally laid exterior material 9A, as in this Example 4. In this embodiment, the upper and lower stages of the step face the wind blown by the aforementioned protrusions 32a, 32b, respectively, thereby providing a high blocking effect.
