JP 2001-271466 A JP 2002-155603 A JP 60-37360 A Japanese Patent Laid-Open No. 10-18530 JP 2014-214421 A Japanese Utility Model Publication No. 62-124129

  In general, since the eaves have a single structure, there is a problem in that overflowed rainwater falls directly from the eaves when it rains heavily.

  In addition, since various types of eaves fixtures are used to attach the eaves to the roof, the number of parts and variations of the eaves fixtures have increased. Moreover, since the eaves must be attached with a drainage gradient, the structure of the eaves attachment is complicated. For example, the thing of patent document 1 had a special structure which attaches an eaves wall to a building main body simultaneously with a decorative member.

  Furthermore, since the eaves fixture did not have the function of temporarily holding the eaves, it was necessary to continue to support the long eaves when installing eaves etc. on the eaves part of the roof. The burden on the workers was great.

  And in above-mentioned patent document 2 and patent document 3, the outer flange part provided in the both-sides upper edge part of the eaves ridge is received from the lower side by the latching | locking part provided in the roof part. Is installed. However, Patent Document 2 and Patent Document 3 have a problem that rainwater overflowing the eaves cannot be prevented from falling directly from the eaves during heavy rain. Also, there was no means for temporarily holding the eaves. And in patent document 4, it is trying to fix an eaves bowl directly to an eaves ceiling. However, since the thing of patent document 4 has directly fixed the eaves to the eaves ceiling, there was a problem that rainwater overflowing the eaves was directly applied to the eaves ceiling and wetted the eaves ceiling.

  Moreover, in patent document 5, piping is connected with respect to the drain port formed in the roof material. In Patent Document 6, the upper panel of the roof is processed into a bowl shape. However, Patent Documents 5 and 6 are not general because they have special structures that do not use eaves.

  Accordingly, the main object of the present invention is to solve the above-described problems.

In order to solve the above problems, the present invention provides:
An eaves bowl is arranged under the eaves part of the roof,
A secondary cage is disposed under the eaves so as to cover the eaves.

  According to the present invention, the above configuration makes it possible to easily install a secondary cage for preventing eaves overflow.

A secondary basket 32 is disposed below the eaves bowl 31 so as to cover the eaves bowl 31.

  Here, the eaves rod 31 is a long one extending along the lower end of the eaves tip portion 21 (in a direction orthogonal to the paper surface of FIG. 1). Further, the secondary rod 32 is a long one extending over the entire length of the eaves rod 31. The secondary basket 32 has a U-shaped cross section that can accommodate at least the lower part of the eaves basket 31. A plurality of spacers 33 are installed between the eaves basket 31 and the secondary basket 32 with a predetermined interval in the longitudinal direction.

  The eaves rod 31 and the secondary rod 32 have a required drainage gradient with respect to the extending direction. As shown in FIGS. 3 (a) and 3 (b), the eaves bowl 31 is provided with an inclined portion 31a (w1 <w2) on the bottom surface to form a drainage gradient. The drainage gradient of the secondary basket 32 will be described later. The spacers 33 are shorter than the eaves rod 31 and the secondary rod 32, and as shown in FIGS. 4 (a), 4 (b) and 4 (c), spacers having different heights are used depending on the drainage gradient. The The spacer 33 may be any type, but the spacer 33 (A, B, C) in the figure has a hat-shaped cross-section of a metal spacer body 33a with elastic members 33b, 33c attached to the upper and lower surfaces, etc. It is said that.

  (1-2) The eaves rod 31 is arranged in direct contact with the roof plate 12 constituting the roof 3 below the eaves portion 21.

  Here, the roof frame 14 in the roof unit 7 is configured such that only the roof plate 12 is extended at the eaves portion 21. And as shown in FIG. 5, the water flow hole 41 is formed in the lower part of the eaves part 21 of the roof board | plate material 12. As shown in FIG. One water flow hole 41 is formed for each roof plate 12. The flowing water hole 41 is a long hole extending in the longitudinal direction of the eaves bowl 31. The eaves bowl 31 has a rectangular tube shape, and an opening 42 communicating with the water flow hole 41 is formed on the upper surface of the eaves bowl 31. A sealing material 43 that is in close contact with the peripheral edge of the water flow hole 41 is attached to the peripheral edge of the opening 42 to prevent water leakage (for example, a phenomenon called “gas leakage”). . Note that portions other than the opening 42 on the upper surface of the eaves 31 are closed. In addition, the eaves portion 21 of the roof frame 11 is appropriately provided with a draining portion 45 toward the secondary ridge 32.

  Further, in FIG. 1, a recess 44 for accommodating and installing the upper part of the eaves wall 31 is formed in a cutout shape below the position of the water flow hole 41 in the roof frame 11. The eaves basket 31 is held from the lower side by the secondary basket 32 and the spacer 33 in a state where the opening 42 is disposed in the recess 44 so as to match the flowing water hole 41.

(1-3) The secondary reed 32 is attached to the roof 3 using a reed support member 51.
The eaves support member 51 includes a bolt member 52 (see FIG. 6) that is screwed (or attached) to the roof frame 11 constituting the roof 3.

  Here, the eaves support member 51 may be any type, but is preferably as follows.

  As shown in FIG. 2, the bolt member 52 is a full screw (long bolt) having no head at both ends. A bolt mounting portion 55 is installed on the lower flange portion 11 c of the roof frame 11. The bolt mounting portion 55 is a metal plate parallel to the flange portion 11c, and a screw hole extending in the vertical direction is formed in the bolt mounting portion 55 so that the upper end portion of the bolt member 52 can be screwed vertically. In addition, a nut member 56 to which the upper end portion of the bolt member 52 is screwed is attached to the upper end portion of the screw hole.

  Then, as shown in FIG. 1, the bolt member 52 is provided so as to form a pair on both sides (the eaves side and the eaves side) of the secondary rod 32 in the width direction. As shown in FIGS. 7 and 8, a plurality of pairs of the bolt members 52 are provided with an interval necessary for supporting the secondary rod 32 in the longitudinal direction of the secondary rod 32.

Furthermore, a step (height adjustment step) of giving a drainage gradient to the secondary rod 32 by changing the height of the support plate 61 by changing the screwing position of the height adjustment nut 66 to the bolt member 52 is performed.

  In addition, before installing the secondary basket 32, the process (eave basket installation process) of accommodating the eaves basket 31 through the spacer 33 inside the secondary fence 32 is performed.

  <Effect> According to this embodiment, the following effects can be obtained.

  The rainwater that has fallen on the roof 3 of the building 1 flows down the roof plate 12, flows into the eaves 31 from the water hole 41 formed in the lower edge of the roof plate 12, and from the eaves 31 (through the eaves ) It is discharged to the outside. Also, if rainwater overflows from the eaves bowl 31 during heavy rainfall, the overflowing rainwater can be received by the secondary fence 32 disposed below the eaves bowl 31. Rainwater received by the secondary dredge 32 is discharged to the outside (via the dredge).

  And the roof 3 and the eaves wall 31 can be put together into a simple structure by installing the eaves wall 31 (and the secondary wall 32) in the position below the flowing water hole 41 formed in the roof board | plate material 12. FIG. The appearance around the eaves can be improved.

  (Operational Effect 1-1) The eaves bowl 31 is arranged below the eaves part 21 of the roof 3 and the secondary eaves 32 are arranged under the eaves bowl 31 so as to cover the eaves bowl 31. did. Thus, by providing the secondary rod 32 on the lower side of the eaves rod 31 to form a double rod structure, overflow of the eave rod 31 can be reliably prevented.

  (Effect 1-2) The eaves rod 31 is arranged to be in direct contact with the roof plate 12 constituting the roof 3 below the eaves portion 21. Thereby, the installation space of the eaves basket 31 can be shortened in the vertical direction, and the eaves basket 31 and the secondary basket 32 can be simultaneously installed in a narrow space.

  Further, the eaves rod 31 is supported by the secondary rod 32 through the spacer 33, so that when the eave rod 31 is covered with the secondary rod 32 to form a double structure, the mounting structure of the eaves rod 31 becomes unnecessary. And the heel support structure can be greatly simplified.

  (Effect 1-3) The secondary rod 32 was attached to the roof 3 using the rod support member 51. Thereby, it becomes possible to attach the secondary rod 32 to the roof 3 independently, and the attachment work of the secondary rod 32 can be simplified.

  In addition, the heel support member 51 includes a bolt member 52, and the bolt member 52 is screwed to the roof frame 11 constituting the roof 3. Thereby, since the bolt member 52 can be easily set only by screwing to the roof frame 11, installation of the eaves support member 51 can be facilitated. Moreover, since the secondary rod 32 is finally fixed to the roof frame 11, the secondary rod 32 can be firmly attached.

Further, the support plate 61 is attached to the bolt member 52. Thus, after temporarily holding the bottom 32a of the secondary rod 32 with the support plate 61, the position of the support plate 61 is moved up and down with respect to the bolt member 52, thereby forming the secondary rod 32 for forming a drainage gradient. Can be easily adjusted.

  At this time, since the bottom portion 32a of the secondary rod 32 is temporarily held by the rod support member 51, the installation work of the secondary rod 32 is facilitated, and the burden on the operator can be reduced.

  And the eaves support member 51 is provided with the bolt member 52 and the support plate 61, whereby the structure of the eaves support member 51 can be simplified. Moreover, since the structure of the eaves support member 51 becomes simple, the number of parts and parts variations can be reduced, and the eaves part 21 having various shapes and structures can be shared.

  (Effect 1-5) The process of attaching the bolt member 52 that constitutes the eaves support member 51 to the roof frame 11 that constitutes the roof 3 (the bolt attachment process of FIG. 11), and the lower side of the eaves portion 21 of the roof 3 A step of arranging the secondary rod 32 (secondary rod arranging step of FIG. 12), and attaching the support plate 61 and the height adjusting nut 66 to the bolt member 52 to temporarily hold the bottom 32a of the secondary rod 32. Step (temporary holding step of FIGS. 13 to 15) is performed, and further, the height of the support plate 61 is changed by changing the screwing position of the height adjusting nut 66 to the bolt member 52, thereby changing the secondary rod 32. A process of providing a drainage gradient (height adjustment process) is performed.

  At this time, by attaching the height adjusting nut 66 to the bolt member 52 through the support plate 61, the scissor support member 51 having a simple structure can be configured. Then, the support plate 61 temporarily holds the bottom 32 a of the secondary rod 32, and the position of the height adjusting nut 66 screwed to the bolt member 52 is changed. By adjusting the height of the eaves 32, installation of the eaves eaves 31 and the secondary eaves 32 can be facilitated. As for the eaves bowl 31, the secondary eaves 32 may be attached as described above after first being installed in the eaves part 21, or the eaves bowl 31 is placed in the secondary eaves 32.
