  Embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  Prior to description of the eaves-end reinforcement structure according to the present embodiment, first, an eaves-end ventilation structure in a building in which a ventilation opening for shed ventilation is provided on the eave end side will be briefly described. As shown in FIG. 5, the ventilation member 2 for shed ventilation is provided below the eaves portion of the field board 11 as a roof base material and on the outdoor side (eave side) from the nose cover member 14. ing. The ventilation member 2 also functions as a drainer, and ventilation and waterproofing are realized by the ventilation member 2. In addition, the ventilation member 2 shown in FIG. 5 has the same structure as the eaves ventilation apparatus for which this applicant applied as Japanese Patent Application No. 2013-67217 as an example. The ventilation member 2 and the surrounding structure will be briefly described.

  The nose-hiding draining member 15 includes a vertical surface portion that is fixed in contact with the outdoor surface of the nose-hidden member 14, an inclined portion that is located above the vertical surface portion and that is along the inclination of the roof, and under the vertical surface portion. It is located on the side and has a lower edge portion that goes around to the lower side of the eaves top plate 17 (FIG. 1). The upper part of the draining part 16 is inserted between the field board 11 and the roof finishing material 12 (FIG. 1). A bent portion is formed at the distal end portion of the draining portion 16, and the distal end of the inclined portion of the nasal cover draining member 15 is engaged in the bent portion.

  The main body 21 of the ventilation member 2 is integrated with the nasal cover draining member 15 by being fixed to the lower surface of the inclined portion with a rivet. An opening 150 is provided in the inclined portion of the nasal cover draining member 15. A concave portion is provided below the main body portion 21, and a plurality of slits 21 a as ventilation openings are formed on the opposing surface. Further, a ventilation port 21 b communicating with the opening 150 of the nasal cover draining member 15 is also formed above the main body 21. Therefore, the outside air enters the main body 21 through the slit 21a, is returned by the internal water return plate 22, and is then guided from the ventilation port 21b to the cabin space. The ventilation member 2 is disposed above the ridge 18 fixed to the vertical surface portion of the nasal cover drainage member 15.

  Here, a ventilation space (ventilation port) 10 is formed between the lower surface of the field board 11 and the upper surface of the nasal cover member 14 in order to send the outside air sent out from the ventilation member 2 to the cabin space. In this case, the eaves part 110 of the field board 11, that is, the take-out part positioned on the eaves side of the rafter 13 is not supported from below. Therefore, the strength of the eaves portion 110 of the field board 11 in such a building is lower than that of a building that does not have a ventilation port on the eaves side.

  Therefore, in the present embodiment, an eaves edge reinforcing tool is provided at the position of the ventilation space 10. Below, the structure of the building which provided the eaves edge reinforcement, ie, the eaves edge reinforcement structure, is demonstrated in detail.

(About the eaves reinforcement structure)
FIG. 1 is a cross-sectional view showing an eaves edge reinforcing structure according to the present embodiment. In FIG. 1, the eaves side of the building is indicated by an arrow A1. In the present embodiment, the direction including the eaves side and the opposite side (the left-right direction on the paper surface) is referred to as the “depth direction”. Further, on the horizontal plane, a direction orthogonal to the depth direction (a direction penetrating the paper surface) is referred to as a “girder direction”.

  As shown in FIG. 1, the eaves-end reinforcement 3 is provided in the ventilation space 10 shown in FIG. 5. That is, the eaves edge reinforcement 3 is attached between the field plate 11 and the nose cover member 14.

  The base plate 11 is a roof base material that supports the roof finishing material 12 from below. The field board 11 is supported from below by a plurality of rafters 13. The plurality of rafters 13 are arranged away from each other in the girder direction. The nasal concealment member 14 extends in the girder direction in contact with the lower side of the eaves side end surface 13a of the plurality of rafters 13. The nasal concealment member 14 is a nasal concealment base having a thickness in the depth direction, and a vertical surface portion of the nasal concealment draining member 15 is fixed to the front side (eave side).

  A specific example of the structure and arrangement position of the eaves-end reinforcement 3 will be described with further reference to FIGS. FIG. 2 is a cross-sectional view of the eaves edge reinforcing tool 3. FIG. 3 is a plan view showing the eaves edge reinforcement 3 when viewed from the direction indicated by the arrow III in FIG. 2. FIG. 4 is a perspective view schematically showing a state in which the eaves edge reinforcement 3 is attached to the rafter 13. In FIG. 4, the structure of the eaves below the field board 11 is shown. In FIG. 4, the direction of the digit is indicated by an arrow A2.

  The eaves-end reinforcement 3 extends in the spar direction and is formed of a rigid member (for example, steel). The eaves-end reinforcing tool 3 is connected to the base portion 31 that is in contact with the wall surface of the eaves side of the rafter 13 at least above the nose cover member 14, and the roof support that supports the base plate from below by being connected to the upper end portion of the base portion 31. Part 32.

  The base portion 31 extends in the girder direction so as to contact at least two adjacent rafters 13. The base portion 31 includes an abutting portion 41 that abuts on the upper side of the eaves-end side end surface 13 a of the rafter 13, and a non-abutting portion 42 that is adjacent to the abutting portion 41 and does not abut against the rafter 13. The non-contact portion 42 is disposed between the adjacent rafters 13. The non-contact portion 42 is provided with a vent 310 for sending outside air from the ventilation member 2 into the cabin space. In the present embodiment, a plurality of vent holes 310 adjacent to each other in the girder direction are provided in each non-contact portion 42.

  In the present embodiment, the base portion 31 has a contact portion 41 for each pitch of the rafters 13. Each contact portion 41 is provided with a through hole 410 for penetrating the fixture 50 such as a screw. Thereby, the base part 31 is firmly fixed to the plurality of rafters 13.

  The roof support portion 32 is connected to the upper end portion of the base portion 31 and extends in the girder direction in contact with the lower surface of the field plate 11. It is desirable that the eaves side end edge of the roof support portion 32 extend to the eaves side rather than the eaves side end edge of the upper end surface 14a of the nose masking member 14. That is, as shown in FIG. 2, the depth dimension L1 of the roof support portion 32 is desirably larger than the depth dimension L3 (FIG. 4) of the upper end surface 14a of the nose masking member 14. Thereby, the field board 11 can be supported in a wide range. Note that the “depth dimension” in the present embodiment indicates not the length of each part in the depth direction but the distance from one end to the other end.

  The eaves-end reinforcing tool 3 further includes a standing wall portion 34 orthogonal to the base portion 31 and the roof support portion 32 in order to increase the strength in the vertical direction. The standing wall portion 34 is disposed so as to be orthogonal to the contact portion 41 of the base portion 31. More specifically, the standing wall portion 34 is provided at a boundary position between the through hole 410 of the contact portion 41 and the non-contact portion 42. In the case of the contact part 41 provided with the non-contact part 42 on both sides, it is desirable that the standing wall part 34 is provided on both sides of the contact part 41. In addition, the standing wall part 34 may be provided not in the above-described boundary position but in a portion (for example, between the plurality of vent holes 310) of the non-contact portion 42 where the vent hole 310 does not exist. Alternatively, it may be provided at both the boundary position and the non-contact portion 42.

  In addition, the eaves tip reinforcing tool 3 is preferably connected to the lower end portion of the base portion 31 and includes a facing portion 33 that faces the upper end surface 14 a of the nose masking member 14. That is, it is desirable that the eaves edge reinforcement 3 has a substantially U-shaped cross section and is attached so that the opening faces the eaves side. In this case, it is desirable that the standing wall portion 34 is provided so as to be orthogonal to the facing portion 33. The intersecting angle between the standing wall portion 34 and the peripheral portion does not have to be a right angle, but may be an angle close to 90 degrees, for example, 90 degrees ± 5 degrees.

  The facing portion 33 faces the upper end surface 14a of the nose masking member 14 in a contact state. Thereby, even when a load is applied to the eaves edge part 110 of the field plate 11, the load can be supported by the nose cover member 14. The depth dimension L2 of the facing part 33 may be smaller than the depth dimension L1 of the roof support part 32. Specifically, the eaves side end edge of the facing part 33 may be substantially the same position as the eaves side end edge of the upper end surface 14 a of the nose masking member 14. That is, the depth dimension L2 of the facing portion 33 may be substantially the same as the depth dimension L3 of the upper end surface 14a of the nose masking member 14. Alternatively, it may be smaller than the depth dimension L3 of the upper end surface 14a of the nose masking member 14.

  When the eaves-end reinforcing tool 3 includes the facing portion 33, the shape of the standing wall portion 34 is, for example, a quadrangular shape. Specifically, the standing wall portion 34 has a quadrangular shape having apexes at the upper and lower end portions of the base portion 31, the tip portion of the roof support portion 32, and the tip portion of the facing portion 33. The standing wall portion 34 only needs to be fixed to at least the base portion 31. For example, the eaves edge reinforcing tool 3 may further include an attachment portion (not shown) that is connected to the edge of the standing wall portion 34 on the base portion 31 side and is superimposed on the surface of the abutment portion 41 on the eaves side. . In this case, the attachment portion may have a through hole at the position of the through hole 410 and be overlapped on the entire surface of the contact portion 41 on the eaves side. By doing in this way, the intensity | strength of the eaves edge reinforcement 3 can also be raised more.

  As shown in FIGS. 3 and 4, the facing portion 33 is connected to the non-contact portion 42 of the base portion 31, and defines the boundary position between the through hole 410 of the contact portion 41 and the non-contact portion 42. It is the end. Specifically, the facing portion 33 in the present embodiment is connected to at least the entire lower end portion of the non-contact portion 42. Thereby, the space for attaching the fixing tool 50 is securable. That is, since the facing portion 33 does not exist below the through hole 410 and the space below the through hole 410 is exposed, the facing portion 33 does not get in the way when the eaves edge reinforcing tool 3 is fixed to the rafter 13. The fixing tool 50 can be driven easily from the eaves side. In the present embodiment, since the standing wall portion 34 is disposed at the boundary position between the through hole 410 and the non-contacting portion 42 of the contact portion 41, the facing portion 33 intersects the standing wall portion 34. The end position is the end point.

  As described above, the eaves end reinforcement 3 is fixed to the rafter 13 as a structural frame of the building, and has the roof support portion 32 that is longer than the nose cover member 14 on the eaves side. Therefore, even in a building in which a ventilation path is provided between the field plate 11 and the nose cover member 14, the strength of the eaves portion of the field plate 11 can be increased. Further, a standing wall portion 34 is provided so as to be orthogonal to the base portion 31, the roof support portion 32, and the facing portion 33. Therefore, even if a large load is applied to the eaves portion 110 of the field base plate 11 due to snow or the like, the load can be supported by the eaves end reinforcement 3.

  In the present embodiment, the base portion 31 is fixed to the rafter 13 by the fixing tool 50 such as a screw, but may be fixed by an adhesive or the like. In this case, the contact portion 41 of the base portion 31 may not include the through hole 410. In this case, the facing portion 33 may be connected to the entire lower end portion of the base portion 31 without being interrupted by the contact portion 41.

  Further, the abutting portion 41 of the base portion 31 abuts against the eaves end side surface 13a of the rafter 13 and is fixed to the rafter 13 at the abutting portion 41. However, a member for fixing to the rafter 13 separately. May be provided. Or when the base part 31 is divided | segmented and arrange | positioned by making two adjacent rafters 13 into 1 unit, even if the contact part 41 is contact | abutted and fixed to the side surface 13b (FIG. 4) of the eaves side of the rafter 13. Good.

  Moreover, although the non-contact part 42 of the base part 31 was demonstrated as a tangible member connected to the width direction (girder direction) edge part of the contact part 41, an intangible member may be sufficient. That is, all of the non-contact portions 42 may function as vent holes.

  Further, although the facing portion 33 is in contact with the upper end surface 14a of the nose masking member 14 in a contact state, it may be in a non-contact state. Even in such a case, the load 33 can be supported by the nasal concealment member 14 because the facing portion 33 comes into contact with the upper end surface 14a of the nasal concealment member 14 when the distal end side of the field board 11 is bent. . In this case, the facing portion 33 may be disposed so as to extend in the horizontal direction and be substantially parallel to the upper end surface 14a of the nose masking member 14, for example, the eaves side is inclined obliquely upward. Also good.

  In the present embodiment, the facing portion 33 is connected to at least the entire lower end portion of the non-contact portion 42. However, the facing portion 33 may be connected only to the central region excluding the end portion of the non-contact portion 42 in the digit direction. That is, the facing portion 33 only needs to be selected so that the length in the girder direction exposes the space below the through hole 410 of the contact portion 41 in order to secure the mounting space for the fixture 50.

  In addition, although the roof base material located above the nose concealment member 14 is the field board 11, it is not limited and may be, for example, Hiroshi Komai. Moreover, the position and structure of the ventilation member 2 are not limited to the said example.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
