Abstract
Description
[Technical field]
[0001] The present invention relates to a canopy structure and a canopy system. [Background technology]
[0002] Traditionally, eaves, which are small roofs for protection from the sun and rain, have been installed on the exterior walls of houses, etc. When installing eaves, additions are sometimes attached to improve the aesthetic appearance and to prevent problems such as rain leaks due to their installation. For example, Patent Document 1 discloses an adjustment material located under the eaves installed at the entrance of a house. The adjustment material forms part of the exterior wall while unifying the design of the sash window frame located at the top of the eaves and the entrance sash located at the bottom of the eaves.
[0003] Patent Document 2 discloses an opening frame that is attached to the edge of a rectangular opening in an exterior wall so as not to protrude from the exterior wall surface and to be watertight with the opening edge. A canopy that protrudes to the outside can be freely attached to the opening frame. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 6-67655 [Patent Document 2] JP 2002-242537 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, the structures described in Patent Documents 1 and 2 are not configured to actively drain rainwater to the outdoors beyond the exterior wall, and there is room for improvement, such as the inability to easily waterproof the structure.
[0006] Therefore, an object of the present invention is to provide an eave structure and an eave system that facilitates weatherproofing between the exterior wall above the eaves and the eaves. [Means for solving the problem]
[0007] [1] An eaves structure according to one embodiment of the present invention is a eaves structure having a covering material that covers the area between an eaves that protrudes outdoors beyond an exterior wall and an opening located below the eaves, wherein the covering material protrudes outdoors beyond the exterior wall and has an attachment portion to which the eaves can be attached.
[0008] [2] In the above [1], it is preferable that the covering material is sandwiched between the eaves and a steel building component, and the steel building component is positioned above the opening and is provided on the exterior wall.
[0009] [3] In the above item [2], it is preferable that the steel building component protrudes toward the outdoors beyond the exterior wall.
[0010] [4] In the above [3], it is preferable that the first part, which is the part of the cover material that is sandwiched between the eaves and the steel building component, is provided with a first hole through which a first fastening member for attaching the cover material to the steel building component is inserted.
[0011] [5] In the above [4], it is preferable that a second portion of the cover material below the first portion is provided with a second hole through which a second fastening member is inserted for attaching the cover material to a steel material, and the steel material is provided below the steel building component.
[0012] [6] In the above item [5], it is preferable that the second hole overlaps with a horizontal gutter provided under the eaves when viewed along the direction in which the eaves extend.
[0013] [7] In any of [2] to [6] above, it is preferable that both longitudinal ends of the cover material are folded, and that the folded portions of the cover material overlap the steel building component when viewed along the longitudinal direction.
[0014] [8] In the above item [7], it is preferable that the surface of the outer wall is wavy having peaks and valleys, and the positions of the folded portions of the cover material correspond to the positions of the valleys.
[0015] [9] In any of [2] to [6] above, it is preferable that a furring strip is provided between the steel building component and the opening, and that the covering material covers the furring strip when viewed along the direction in which the eaves extend.
[0016]
[10] An eaves system according to one embodiment of the present invention is an eaves system comprising an eaves that protrudes outdoors beyond an exterior wall, and a covering material that covers the space between the eaves and an opening located below the eaves, wherein the covering material protrudes outdoors beyond the exterior wall and is capable of being attached to the eaves. Effect of the Invention
[0017] According to the present invention, the cover material protrudes from the exterior wall toward the outside, so that rainwater running down the exterior wall flows to the outside through the cover material. This makes it unnecessary to use water-stopping sealing such as caulking, which is required when the eaves are directly attached to the exterior wall, and makes it easy to provide rainproofing between the exterior wall above the eaves and the eaves.

[Figure 4]FIG. 11 is a perspective view of an eave system according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] [First embodiment] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.
[0020] Fig. 1 is a perspective view of an eaves system 100 according to a first embodiment of the present invention. As shown in Fig. 1, the eaves system 100 of this embodiment includes an eaves 50 that protrudes to the outdoors beyond an exterior wall 70 of a house, for example, and an eaves structure 1 for attaching the eaves 50 to the exterior wall 70. An opening 71 in which a window or door can be installed is formed in the exterior wall 70, and the eaves 50 are provided above the opening 71.
[0021] First, we will explain the exterior wall 70 to which the eaves 50 are attached, and the furring strips 72. As shown in Fig. 2, the exterior wall 70 is attached to the furring strips 72, and the multiple furring strips 72 are supported by a predetermined frame or columnar member (not shown). The furring strips 72 are base members extending horizontally. In this embodiment, the furring strips 72 are made of square steel pipes, but are not limited to this and may be made of wood or the like. The exterior wall 70 is a corrugated steel plate siding having peaks 74 and valleys 75. The peaks 74 are portions of the exterior wall 70 that are convex toward the exterior, and the valleys 75 are portions that are recessed relative to the peaks 74. The exterior wall 70 is fixed to the furring strips 72 at the valleys 75 by fastening members 90 such as drill screws. The exterior wall 70 is not limited to steel plate siding, and may be siding made of other materials such as resin, mortar, or an ALC panel.
[0022] An opening 71 formed in the exterior wall 70 has, for example, a rectangular shape, and a window or door (not shown) is attached to the opening 71. The periphery of the opening 71 may be appropriately reinforced by other base members.
[0023] Next, the eaves 50 will be described. The eaves 50 is a small roof for shade and rain protection, and has an eaves main body 51 and a bracket portion 52. The eaves main body 51 is a plate-like member formed of a metal such as aluminum. The shape of the eaves main body 51 is, for example, rectangular, and includes a linear portion that runs along the exterior wall 70. The width of the eaves main body 51 (the width along the surface and horizontal direction of the exterior wall 70) can be appropriately selected according to the width of the opening 71.
[0024] The bracket portion 52 is a member for fixing the eaves body 51 to the object to which it is to be attached (in this embodiment, the covering material 2 and the steel building component 3 described below), and has a gripping portion 53 that grips the eaves body 51, and a fixing portion 54 that is fixed to the object to which it is to be attached. An end of the eaves body 51 is inserted into the gripping portion 53. The eaves body 51 is fixed to the gripping portion 53 by fastening members 91 such as bolts and nuts that pass through the gripping portion 53 and the eaves body 51. The fixing portion 54 is connected to the gripping portion 53 and has a contact surface 54A that comes into surface contact with an object to which the fixing portion 54 is to be attached. A part of the gripping portion 53 and the fixing portion 54 may be connected by a snap fit 55.
[0025] A cover 56 can be attached around the base of the canopy 50. Appropriate sealing can be applied between the cover 56 and the bracket portion 52. The configuration of the eaves 50 is not limited to that described above, and it is sufficient if it functions as an eaves and can be fixed to the object to which it is attached. For example, the eaves main body 51 and the bracket portion 52 may be integrated.
[0026] Next, the connection structure between the exterior wall 70 and the eaves 50 will be described. The eaves 50 is not directly fixed to the exterior wall 70, but is fixed to the exterior wall 70 via the eaves structure 1. The eaves structure 1 of this embodiment has a cover material 2, a steel building component 3 fixed to a furring strip 72, and a steel material 4 provided on the underside of the steel building component 3.
[0027] The exterior wall 70 is formed with a rectangular hole 76 for attaching the steel building component 3. In other words, the steel building component 3 is fixed to the furring strip 72 so as to protrude to the outside through the rectangular hole 76.
[0028] The steel building component 3 is located above the opening 71, and is installed so as to be supported by the exterior wall 70 via furring strips 72. The steel building component 3 is formed with through holes 32 for fixing the eaves 50, and the eaves 50 is fixed by a first fastening member 92. Fixing the eaves 50 via the steel building component 3 can improve workability. The steel building component 3 is arranged to extend horizontally along the surface of the exterior wall 70, and is fixed to the furring strips 72 so that a portion of it protrudes outside beyond the surface (ridges 74) of the exterior wall 70. The steel building component 3 of this embodiment is formed from a channel steel with a C-shaped cross section, and is arranged so that the flat surface 31 of the web 3A is parallel to the surface of the exterior wall 70, and the flange 3B is fixed to the furring strips 72. The steel building component 3 is not limited to a channel steel, and may be, for example, a square steel pipe.
[0029] The steel building component 3 is fixed to the upper furring strip 72A and the lower furring strip 72B by fastening members (not shown) such as bolts. The method of fixing the steel building component 3 to the furring strip 72 is not limited to this, and welding may also be used. Note that the upper furring strip 72A is not essential, but the lower furring strip 72B is essential, for example, to attach a door to the opening 71. In other words, the furring strip 72 is always provided between the steel building component 3 and the opening 71.
[0030] The steel material 4 has the function of extending the flat surface 31 of the steel building component 3 downward to support the cover material 2, and has a first surface 41 that is positioned on the same plane as the flat surface 31 of the steel building component 3 and to which the cover material 2 is fixed, and a second surface 42 that is welded to the flange 3B of the steel building component 3. The steel material 4 can be formed, for example, from a steel plate with a thickness of 2 mm. The configuration of the steel material 4 does not have to be as described above as long as the first surface 41 can be positioned on the same plane as the flat surface 31 when provided on the underside of the steel building component 3.
[0031] The covering material 2 protrudes outside beyond the exterior wall 70 and is sandwiched between the eaves 50 and the steel building component 3, and covers the area between the eaves 50 and the opening 71 as shown in Fig. 1. When viewed along the direction in which the eaves 50 extend (the direction extending outside), the covering material 2 is formed so as to cover the furring strips 72, more specifically, to cover the lower furring strips 72B. In other words, the covering material 2 is large enough to cover the steel building component 3 and the lower furring strips 72B. 3, the cover material 2 has a planar main panel 21, and both longitudinal ends of the main panel 21 are folded to form sub-panels 22. The cover material 2 is formed so that the width of the cover material 2 is approximately the same as the width of the canopy 50.
[0032] The cover material 2 can be formed, for example, from an aluminum steel plate (e.g., 2 mm thick). The first portion 21A of the cover material 2, which is a portion sandwiched between the eaves 50 and the steel building component 3, is provided with a first hole 23 through which a first fastening member 92, such as a bolt and a nut, is inserted for attaching the cover material 2 to the steel building component 3. The first portion 21A and the first hole 23 function as an attachment portion to which the eaves 50 can be attached. In this way, by providing the first hole 23 in the first portion 21A, the first hole 23 can be made less noticeable. Also, by inserting the first fastening member 92 into the base of the eaves and then further inserting the inserted first fastening member 92 into the first hole 23, the base of the eaves can be better fitted. As is also clear from Figure 2, the first fastening member 92 for fixing the eaves 50 to the covering material 2 is used as well as the first fastening member 92 for fixing the covering material 2 to the steel building component 3. The bolt of the first fastening member 92 is inserted from the outdoor side, and the nut is tightened on the indoor side. In this way, even if the bolt is somewhat long, it can be fastened without interfering with other components, and the bolt length can be consolidated regardless of whether or not the covering material 2 is present. If the bolt is inserted from the indoor side, it becomes necessary to precisely determine the bolt length, taking into account interference between the bolt tip and the eaves main body 51.
[0033] The second portion 21B of the cover material 2 below the first portion 21A is provided with a second hole 24 through which a second fastening member 93 (fastener material) for attaching the cover material 2 to the steel material 4 is inserted. The second portion 21B of the cover material 2 is fixed to the steel material 4 by the second fastening member 93. The second fastening member 93 may be a drill screw, or may be a member other than a drill screw, such as a bolt or nut. By setting the plate thickness of the steel material 4 to about 2 mm, the second fastening member 93 can be a drill screw. In the case of a drill screw, it is not necessary to provide the second hole 24 in the cover material 2 before the cover material 2 is attached to the outer wall 70. In addition, in the case of a drill screw, it is possible to further improve the aesthetic appearance.
[0034] The sub-panel 22, which is the folded portion of the covering material 2, overlaps with the steel building component 3 when viewed along the longitudinal direction of the covering material 2. This makes it possible to improve the aesthetic appearance by more reliably hiding the steel building component 3 even if the covering material 2 protrudes more from the exterior wall 70. Also, by preventing the steel building component 3 from being exposed to rain, it is possible to easily achieve rainproofing and waterproofing. Furthermore, by covering the covering material 2 with the steel building component 3, the frequency of maintenance of the steel building component 3 can be reduced.
[0035] In addition, the covering material 2 is disposed so that the sub-panel 22 of the covering material 2 corresponds to the position of the valley portion 75 of the exterior wall 70. This reduces the gap between the covering material 2 and the exterior wall 70, allowing for more reliable weatherproofing.
[0036] Additionally, an upper drain 11 is attached to the top of the cover material 2 and the steel building component 3. The upper drain 11 is made of a steel plate with a thickness of approximately 0.5 mm and is formed to a width corresponding to the cover material 2. The upper drain 11 is composed of an upper drain upper part 11A sandwiched between the exterior wall 70 and the furring strip 72, an upper drain middle part 11B that runs along the top surface of the steel building component 3, and an upper drain lower part 11C that is sandwiched between the cover material 2 and the steel building component 3, and has a lightning bolt-shaped cross section. In this way, by providing an upper drain 11 so as to cover the steel building component 3, it is possible to easily waterproof the steel building component 3.
[0037] According to the eaves structure 1 of the first embodiment, the cover material 2 protrudes further outdoors than the exterior wall 70, so that rainwater running down the exterior wall 70 flows outdoors via the cover material 2. This eliminates the need for watertight sealing such as caulking that would be required if the eaves 50 were directly installed on the exterior wall 70, for example, and makes it easier to provide rainproofing between the exterior wall 70 and the eaves 50 above the eaves 50. In addition, the durability of the rainproofing can be improved compared to sealing that is prone to deterioration.
[0038] In addition, rainwater adhering to the cover material 2 is less likely to flow onto the outer wall 70 below the cover material 2, making it easy to achieve rainproofing. Furthermore, by attaching the eaves 50 to the exterior wall 70 via the cover material 2, workability and aesthetic appearance can be improved even if the exterior wall 70 has peaks and valleys. In addition, by covering the area between the eaves 50 and the opening 71 with the cover material 2, the need to provide a vertically short exterior wall main body 73 between the lower end of the eaves 50 and the opening 71 can be reduced.
[0039] Furthermore, because the covering material 2 is sandwiched between the eaves 50 and the steel building component 3, it is possible to attach the covering material 2 and the eaves 50 to the steel building component 3 even if there are peaks and valleys in the exterior wall 70. Also, by having the eaves mechanically supported by the steel building component 3, the details of the covering material 2 can be simplified. In addition, by covering the steel building component 3 with the cover material 2, the overall aesthetic appearance can be improved.
[0040] In addition, since the steel building component 3 protrudes to the outside, it is possible to reduce the need for caulking between the steel building component 3 and the exterior wall 70 below the steel building component 3. Even if caulking is required, it is possible to prevent the caulking from being exposed to direct sunlight and suppress deterioration of the caulking.
[0041] In addition, by fixing the second portion 21B, which is the lower portion of the cover material 2, it is possible to prevent the second portion 21B from flapping when the wind blows. In addition, since the second fastening member 93 is easily hidden in the shadow of the eaves 50, it is possible to reduce the possibility that the use of the second fastening member 93 will impair the aesthetic appearance.
[0042] Second Embodiment Next, a description will be given of an eaves system 100A according to a second embodiment of the present invention. Fig. 4 is a perspective view of an eaves system 100A according to the second embodiment of the present invention. As shown in Fig. 4, the eaves 50A of the second embodiment is a so-called inverted slope eaves, in which the tip of the eaves is higher than the base of the eaves, whereas the tip of the eaves of the first embodiment is lower than the base of the eaves. The eaves 50A of this embodiment has a horizontal gutter 60, and rainwater is guided to the base side of the eaves 50A and is led to the horizontal gutter 60. The eaves main body 51 may be reinforced by an arm (not shown).
[0043] The horizontal gutter 60 is provided at the base of the eaves 50, below the eaves main body 51, and extends in the width direction of the eaves 50. A drop opening 61 is provided at a predetermined position of the horizontal gutter 60. In order to cope with the increased weight due to the horizontal gutter 60, etc., the number of first fastening members 92 that fix the eaves 50A to the steel building component 3 is greater than in the first embodiment. In order to increase the number, the first holes 23 are formed in two rows in the vertical direction. The second hole 24 overlaps with a horizontal gutter 60 provided under the eaves 50 when viewed along the direction in which the eaves 50 extend.
[0044] According to the eaves system 100A of this embodiment, the use of the horizontal gutter 60 makes it easy to stop rain falling, and the horizontal gutter 60 hides the second hole 24, improving the aesthetic appearance.
[0045] In addition, in each of the above embodiments, the eaves structure 1 includes the steel material 4, but the steel material 4 is not necessarily required and can be omitted as appropriate depending on the required rigidity, etc. [Explanation of symbols]
