  In recent buildings, there are many cases where a plurality of nose concealment portions having different heights are provided at the eaves of the inclined roof (when the eaves of the inclined roof have steps). In this case, there has been a problem that it is difficult to form the drainage structure at the eaves of the sloped roof with a good appearance.

  This is because when the eaves is installed for each nasal concealment part at different heights and a vertical eave is connected to each eaves, the eaves can be drained efficiently. Because of the downspout, the overall appearance will be worse.

  On the other hand, it is also conceivable to adopt a structure in which adjacent eaves are connected to each other by a kebab, and a series of eaves are drained by a common vertical eave. According to this structure, the number of downspouts in the entire building can be reduced, and the overall appearance is improved.

  However, in this structure, an eaves joint having a dedicated shape corresponding to the slope of the inclined roof is required as a joint for connecting the eaves eaves and the keraba eaves. If the shape of the eaves joint is a shape that does not correspond to the slope of the sloped roof, when the eaves joint and the kebab joint are forcibly connected with this eaves joint, the unity of the exterior of the eaves of the building is lost. , Looks will get worse.

  The present invention is an invention that solves the above-described problem, and provides a roof drainage structure that can form a drainage structure that uses an eave ridge or the like, even when the eaves of an inclined roof have a step. That is the purpose.

  In order to solve the above problems, the present invention is a roof drainage structure having the following configuration.

The present invention provides at least two eaves attached to the eaves of a sloped roof, a keraba eaves connecting the ends of the two adjacent eaves connected to each other, and a vertical eave connected to one of the two eaves It comprises. The eaves tip portion includes a first nasal concealment portion, a second nasal concealment portion, and a keraba portion. The first nasal cover part has an eaves-side surface that is inclined so as to be orthogonal to the inclination direction of the inclined roof. The second nasal concealment portion is located higher than the first nasal concealment portion, and has an eave side surface that is inclined so as to be orthogonal to the inclination direction of the inclined roof. The keraba portion connects ends of the first nasal concealment portion and the second nasal concealment portion in a crank shape. The two eaves are a first eave and a second eave. The first eaves rod is disposed in an inclined posture so as to be along the surface of the eaves side of the first nose concealing portion, and is connected in communication with the vertical eaves. The second eaves rod is arranged in an inclined posture so as to follow the eave side surface of the second nose cover. The keraba ridges have a slope corresponding to the inclination of the roof by being connected in communication with each other in a posture orthogonal to the first eave ridge and the second eave ridge .

  It is preferable that the present invention further includes a first eaves joint having a protruding corner shape and a second eaves coupling having a corner shape. The first eaves joint connects the first eaves eaves and the kerber eaves in a direction orthogonal to each other. The second joint connects the kerber rod and the second eave rod in a direction orthogonal to each other.

  Since this invention is the drainage structure of the roof which comprises the said structure, there exists an effect that the drainage structure of the inclined roof which has a level | step difference in the eaves can be formed with good appearance.

  In a state where the rear surface of the fixing plate 70 included in the hanging tool 7 is in contact with the surface 100a of the first nose cover part 100, the fixing plate 70 is fixed using a fixing tool such as a screw. The first eaves rod 20 is applied to the fixed hanger 7 from below, the first eave rod 20 is rotated in a state where the rear ear portion 204 is hooked on the rear ear hooking portion 713, and the front ear portion 203 is moved to the front ear. Hook on the hook portion 712. A lower end portion of the contact piece 711 extending obliquely downward in the rear is in contact with the inner surface of the rear wall 201.

  In this state, the first eaves rod 20 is suspended from the hanger body 71 and attached to the eaves tip 10 of the inclined roof 1. The first eaves rod 20 is disposed so as to maintain a posture (tilting posture) parallel to the inclined surface 100a of the first nose concealing portion 100.

  In the first eaves rod 20 suspended and supported by the hanging tool 7, the rear wall 201 is positioned in parallel with the surface 100 a of the first nose concealment portion 100. The bottom wall 202 of the first eaves rod 20 is located in parallel with the inclination direction D1.

  Although the illustration of the mounting structure of the second eave rod 21 and the keraba rod 3 is omitted, the second eave rod 21 has the same structure using the hanging tool 7 and the eave side surface 101a of the second nose cover 101. Attached to. The second eaves rod 21 suspended and supported by the hanger 7 is arranged in a posture in which the upper side is inclined forward so as to maintain a posture parallel to the surface 101a of the second nose cover part 101. The first eaves ridge 20 and the second eave ridge 21 are inclined at the same angle in the same direction.

  The keraba rod 3 is attached to the eaves side surface 102 a of the keraba portion 102 with the same structure using the hanging tool 7. The eaves side surface 102a is a vertical surface. The keraba rod 3 is suspended and supported by the hanger 7 so as to maintain a posture parallel to the surface 102 a of the keraba portion 102.

  That is, in the building 9 having the drainage structure of the present embodiment, the inclined roof 1 is a structure having a step at the eaves edge, but the vertical gutter 4 need only be installed at one place on the first eave gutter 20 side. Since the appearances of the single house 20, the keraba 3 and the second house 21 are unified, the appearance is good. In addition, the first eave fence 20, the keraba eaves 3 and the second eave fence 21 are all arranged without leaving a large gap in the eaves tip portion 10 of the inclined roof 1 (see FIG. 2). Sometimes the hanger 7 is not greatly exposed, and the appearance is good. In addition, since the first eaves joint 5 and the second eaves joint 6 may be joints of a type orthogonal to the L shape, a common member can be used regardless of the gradient of the inclined roof 1.

In this case, a large gap is created between the surface 100a of the first nose concealment portion 100 and the first eaves ridge 20, and the hanging tool 8 and the like are greatly exposed when looking up from below, and the appearance is deteriorated. Similarly, between the surface 101a of the second nasal concealment part 101 and the second eaves bowl 21, the appearance is also deteriorated. Moreover, the member of the exclusive shape according to the gradient of the inclined roof 1 is needed as the hanging tool 8 or the eaves joint.

  As described with reference to the accompanying drawings, the roof drainage structure of this embodiment includes at least two eaves 2 and 2 attached to the eaves portion 10 of the inclined roof 1 and two adjacent eaves 2 and 2. There are provided a keraba rod 3 for connecting the ends in communication and a vertical rod 4 connected to one of the two eaves 2, 2. The eaves part 10 includes a first nasal cover part 100, a second nasal cover part 101, and a keraba part 102. The first nose-hidden part 100 has an eave-side surface 100 a that is inclined so as to be orthogonal to the inclination direction D <b> 1 of the inclined roof 1, and is connected in communication with the vertical gutter 4. The second nasal concealment portion 101 is located higher than the first nasal concealment portion 100 and has an eave side surface 101 a that is inclined so as to be orthogonal to the inclination direction D <b> 1 of the inclined roof 1. The keraba portion 102 connects the ends of the first nasal concealment portion 100 and the second nasal concealment portion 101 in a crank shape. The two eaves ridges 2 and 2 are the first eave ridge 20 disposed in an inclined posture along the eave side surface 100a of the first nasal concealment portion 100, and the eave side of the second nasal concealment portion 101. It is the 2nd eaves bowl 21 arrange | positioned with the attitude | position inclined so that the surface 101a of this may be followed. The keraba rod 3 is connected in communication with the first eave rod 20 and the second eave rod 21 so as to be orthogonal to each other.

  According to the drainage structure of the roof of the present embodiment, the first eave ridge 20 and the second eave ridge 21 that are at different heights are connected in communication with the keraba ridge 3, and the vertical ridge 4 that is connected to the first eave ridge 20 is used. Common drainage can be performed. Therefore, the number of downpipe 4 in the whole building 9 can be reduced, and the whole appearance improves. Further, the first eaves rod 20 is disposed in a posture inclined along the surface 100 a of the first nose cover portion 100, and the second eaves rod 21 is inclined in a posture along the surface 101 a of the second nose cover portion 101. Therefore, it is possible to suppress the hanger 7 and the like from being exposed when looking up from below, and the appearance is further improved. Therefore, although the eaves tip portion 10 of the inclined roof 1 has a stepped shape, the drainage structure at the eaves tip can be formed with good appearance.

  In addition, the drainage structure of the roof according to the present embodiment includes a first corner joint 5 having a protruding corner that connects the first eave bar 20 and the keraba bar 3 in a direction orthogonal to each other, and the keraba bar 3 and the second eave bar. And a corner-like second eaves joint 6 for connecting 21 in a direction orthogonal to each other.

  Since the roof drainage structure of the present embodiment has the above-described configuration, the first eaves joint 5 and the second eaves joint 6 may be joints of a type orthogonal to the L shape, and the slope of the inclined roof 1 Regardless of this, it is possible to make the members common.

  As mentioned above, although this invention was demonstrated based on embodiment shown to an accompanying drawing, this invention is not limited to the said embodiment. For example, the inclined roof 1 of the present embodiment is an inclined roof that forms part of a gable roof, but may be an inclined roof that forms a roof of another shape such as a single-flow roof. For other configurations, appropriate design changes can be made within the range intended by the present invention.
