Description

  The present invention relates to a structure around an eaves of a building.

  As a conventional structure around the eaves of a building, for example, as described in Patent Document 1, there is a structure in which an eaves drainer and an eaves are arranged in a space between an upper end of an outer wall panel and a tip of an inclined roof.

JP-A-6-123162

In the above-described conventional eaves-end structure, a dropper is connected to the dropout at the bottom of the eaves. In such a structure, there is a need for a space for connecting the dropper below the eaves, so the eaves are installed at a high position away from the partition as a whole, and the building is restricted by diagonal lines, etc. There was a problem that it became easy to violate the legal restrictions on the height of the building.
An object of the present invention is to provide a structure around the eaves of a building that can lower the height of the eaves.

The structure around the eaves of the building according to the present invention includes an outer wall and an eaves portion located at a height higher than the upper end of the outer wall and disposed in a horizontal position that is recessed toward the inside of the building from the outer surface of the outer wall. A partition material having an outer surface that forms a hollow portion that is recessed between an upper end of the outer wall and the eaves portion, and that is recessed toward the inside of the building, and the outer surface of the partition material. An eaves ridge disposed in the depression, and the eave ridge has an opening in an outer standing portion of the eaves ridge.
According to the eaves surrounding structure of the building according to the present invention, the height position of the eaves can be lowered.

  In this specification, “eave portion” means “the edge of the roof”.

  Further, in this specification, the “partition material” means a member for closing a gap between the outer wall and the roof in order to prevent rainwater from entering.

  Moreover, in this specification, the "opening part of the outer standing part of an eaves bowl" means the opening part which penetrates the outer standing part of an eaves bowl. Examples of the opening include a through-hole formed in the outer standing portion of the eaves ridge, a portion that is notched downward from the upper end of the outer erection portion of the eaves ridge, and the like.

  In the structure around the eaves of the building according to the present invention, the shape of the bottom of the eaves is preferably a shape corresponding to the shape of the outer surface of the partition member. In this case, the height position of the eaves can be lowered.

  In the present specification, “the shape of the bottom of the eaves is a shape corresponding to the shape of the outer surface of the partition member” means that the bottom of the eaves extends along the outer surface of the partition member. It means that

  In the structure around the eaves of the building according to the present invention, it is preferable that the partition material has a shape in which a part corresponding to the bottom of the eaves wall is lowered downward from the eaves part side toward the outer surface side of the outer wall. . In this case, the antifouling property can be improved together with the water stopping property.

  In the structure around the eaves of the building according to the present invention, it is preferable that the outer surface of the outer standing portion of the eaves ridge is disposed at a horizontal position protruding to the outside of the building from the outer surface of the outer wall. In this case, it is possible to prevent the outer surface of the outer wall from being contaminated by rainwater flowing down along the outer surface of the outer standing portion of the eaves basket.

  In the structure around the eaves of the building according to the present invention, the lower end of the eaves is connected to the lower end of the outer standing part of the eaves by connecting the horizontal outer edge of the bottom of the eaves downwardly toward the outside of the building. It is preferable that it is an end. In this case, when the building is looked up from below and a part of the bottom of the eaves protrudes from the outer surface of the outer wall, the lower end of the eaves (the lowest part) forms a straight ridgeline. Since it is visible, a part of the bottom of the eaves that protrudes visually from the outer surface of the outer wall does not feel the thickness, and the eaves of the eaves can be reduced.

  In the structure around the eaves of the building according to the present invention, the lower end of the eaves ridge is at a height position that coincides with the horizontal outer end of the partition member, or at a height position lower than the horizontal outer end of the partition member. Preferably there is. In this case, since the partition member is hidden behind the eaves and cannot be visually recognized, it is not necessary to provide a separate cover for the partition member, and the configuration can be simplified.

  In the structure around the eaves of the building according to the present invention, the horizontal outer end of the partition member is a horizontal position that coincides with the outer surface of the outer wall, or the horizontal direction that recedes toward the inside of the building from the outer surface of the outer wall. It is preferable to arrange in the position. In this case, it is easier to conceal the partition material with the eaves in combination with the fact that the outer surface of the outer upright portion of the eaves is arranged in a horizontal position protruding to the outside of the building from the outer surface of the outer wall. Also, in this case, since the partition material is covered with the roof and eaves, rainwater and dust do not fall down on the partition material, so even if the partition material is retracted from the outer surface of the outer wall, dirt adheres to the outer wall. There is nothing.

  ADVANTAGE OF THE INVENTION According to this invention, the eaves surrounding structure of a building which can make the height position of an eaves wall lower can be provided.

The second upright piece 133 of the rafter metal receiving piece 13 serves as a joint portion of a base metal piece 14 to be described later.

  A receding portion B is formed between the upper end 1 e of the outer wall 1 and the eaves portion 2 a of the roof 2. The receding part B is a space for attaching the eaves ridge 4 described later so as not to protrude from the outer surface 1f of the outer wall 1 and the outer surface 2f of the roof 2 (roof material 23).

  Reference numeral 3 denotes a partition member disposed in a retreating portion B formed between the upper end 1 e of the outer wall 1 and the eaves tip portion 2 a of the roof 2. In this embodiment, the partition member 3 has an outer surface 3f that forms a hollow portion D that is recessed toward the inside of the building. The partition member 3 is disposed in the retreating part B where the waterproofing line (outer surface 1f) by the outer wall 1 and the waterproofing line (outer surface 2f) by the roof 2 are interrupted, and prevents intrusion of rainwater from the retreating part B into the building. This is a horizontally long member. Specific examples of the partition member 3 include those that perform the same function as a drainer so that water does not fall or wrap around the wall surface, for example, a waterproof curtain. In this embodiment, the partition member 3 is formed by bending a metal plate such as an aluminum plate. In the present embodiment, the partition member 3 is bent from the first piece 31 standing at a horizontal position on the inner side of the building deeper than the eaves tip (tip) 2 a of the roof 2, and is bent from the lower end of the first piece 31. and a second piece 32 that descends in the direction of the outer surface 1f of the outer wall 1 at θ. Thereby, the lower end of the second piece 32 of the partition member 3 constitutes a horizontal outer end 3 e of the partition member 3. The inclination angle θ is preferably 30 to 40 degrees, more preferably 35 degrees (including an error within ± 2 degrees). Furthermore, in this embodiment, the height position of the horizontal direction outer end 3e of the partition member 3 substantially coincides with the height position of the upper surface 11e of the outer peripheral beam 11. Furthermore, in this embodiment, the partition member 3 is bent further downward from the tip of the third piece 33 and the third piece 33 bent toward the inside of the building at the horizontal outer end 3e of the partition member 3. It has four pieces 34. The third piece 33 and the fourth piece 34, which are the bent portions, are wet sealing materials that stop the gap between the upper end 1e of the outer wall 1 and the second piece 32 of the partition member 3 and the upper end 1e of the outer wall 1. Forming a sealing pocket for filling. In the figure, a state in which the sealing material 18 is arranged is shown. The partition member 3 is attached to the base metal member 14 so that the second piece 32 of the partition member 3 comes into contact with an inclined surface 142f of the base metal member 14 to be described later attached to the outer circumferential beam 11.

  In FIG. 3, reference numeral 4 denotes an eaves bowl disposed in a recess D formed by the outer surface 3 f of the partition member 3. In this embodiment, the eaves bowl 4 is formed by bending a metal plate such as an aluminum plate. In the present embodiment, the eaves bowl 4 includes a bottom 41, an outer standing portion 42 bent at an acute angle upward from the horizontal outer edge of the bottom 41, and an upward from the horizontal inner edge of the bottom 41. It has the inner standing part 43 bent at an obtuse angle. In the present embodiment, the lower end 4e of the eaves rod 4 is a connection end in which the horizontal outer edge of the bottom 41 of the eave rod 4 is connected to the lower end of the outer standing portion 42 of the eave rod 4 downward toward the outside of the building. is there. Moreover, in this embodiment, the upper end of the outer standing part 42 and the inner standing part 43 in the eaves rod 4 is bent at an acute angle toward the inner side of the eaves rod 4. Further, the height position of the upper end of the outer standing portion 42 is slightly lower than the height position of the upper end of the inner standing portion 43. For example, in the case of heavy rain, rainwater overflows toward the outer standing portion 42 side. Yes. In the present embodiment, the eaves rod 4 is attached in a state of being suspended by an eaves rod mounting bracket 15 attached to the base metal piece 14. The eaves mounting bracket 15 is attached to the base metal piece 14 with an interval in the extending direction of the outer peripheral beam 11. Moreover, in this embodiment, the eaves edge drainer 16 is attached to the front-end | tip part of the field board 21. As shown in FIG. The eaves tip drainer 16 extends along the extending direction of the eaves rod 4. The eaves tip drainer 16 is attached to the field board 21 so that the front end 16 a covers the eaves basket 4.

  In this embodiment, between the partition material 3 and the eaves fence 4 and between the partition material 3 and the roof 2 (the back surface thereof) are separated from each other, and the external space and the back of the roof 2 (the roof 2 and the ceiling). The space between them. Thereby, in this embodiment, the introduction path of outside air is formed between the partition material 3 and the eaves wall 4 and between the roof 2 and the eaves wall 4. Specifically, the partition material 3 and the eaves basket 4 are not in contact with each other, and a slight gap C1 is formed. The gap C <b> 1 can have a dimension capable of securing a desired air flow rate, for example, 2 to 10 mm, more preferably 5 to 7 mm. In the present embodiment, a gap C <b> 2 is also formed between the upper ends of the partition member 3 and the base hardware 14 and the roof 2. In the present embodiment, the gap C1 communicates with the gap C2. In the present embodiment, a gap C3 is also formed between the eaves rod 4 and the tip 16a of the eaves tip drainer 16. The gap C3 also communicates with the gap C2. Outside air is introduced into the back of the roof 2 through a route via the gap C1 and the gap C2 and a route via the gap C3 and the gap C2, and warm air at the back of the roof 2 is sequentially provided in the ridge. The ridge ventilation hardware is discharged (both the ridge and the ridge ventilation hardware are not shown). Thereby, natural ventilation by gravity ventilation is made at the back of the roof 2.

  In the present embodiment, a ventilation hardware 17 is installed between the inner standing portion 43 of the eaves cage 4 and the first piece 31 of the partition member 3. The ventilation hardware 17 extends in the extending direction of the outer peripheral beam 11 and is attached to the roof 2. The ventilation hardware 17 is provided with a plurality of small holes 17h for ventilation at predetermined intervals. Thereby, the ventilation hardware 17 prevents the entry of insects or the like from the gap C1 and the gap C3 into the back of the roof 2 while allowing outside air to pass through. In particular, in this embodiment, the ventilation hardware 17 is fixed to the field plate 21 together with the eaves drainer 16 by fastening means F (not shown).

  The base metal member 14 is a member that becomes a base for mounting the partition member 3 and the eaves-mounting bracket 15. The base metal 14 is attached in a state where it is taken out from the outer peripheral beam 11 toward the outside of the building along the extending direction of the outer peripheral beam 11 (a state where it is supported in a cantilever manner). The base metal piece 14 includes a horizontal piece 141 and an inclined piece 142 that is bent from the tip 14a of the horizontal piece 141 so as to have a predetermined inclination angle θ, and the horizontal piece 141 and the inclined piece 142 are substantially in a sectional view. V-shaped. In the present embodiment, the horizontal piece 141 of the base metal piece 14 is placed on the upper surface 11 e of the outer peripheral beam 11. In the present embodiment, the horizontal piece 141 of the base metal piece 14 is joined to the outer circumferential beam 11 by fastening means (bolts) F.

  In the present embodiment, the inclination angle θ of the inclined piece 142 of the base metal piece 14 coincides with the angle on the rear end side (back side) of the partition member 3. Thereby, the back surface of the second piece 32 of the partition member 3 is in contact with the inclined surface 142 f of the inclined piece 142 of the base metal piece 14. Further, in the present embodiment, the base metal piece 14 has a bent portion 143 bent in the vertical direction from the upper end of the inclined piece 142. The bent portion 143 of the base metal piece 14 is joined to the rafter metal piece 13. In the present embodiment, the bent portion 143 of the base metal piece 14 is fixed to the second upright piece 133 of the rafter metal piece 13 by fastening means (bolts) F. The rafter metal receiving piece 13 also functions as a reinforcing metal piece for the base metal piece 14. That is, it is possible to prevent or reduce the bending of the inclined piece 142 on the open rear end side (the side denoted by the symbol θ in the drawing) between the horizontal piece 141 and the inclined piece 142 of the base metal piece 14. Moreover, as above-mentioned, since the said rear end side of the said base metal object 14 is open | released, it is easy for an operator's hand to enter and the base metal object 14 is easily attached (bolt joining) to the outer periphery beam 11. Can do.

  As shown in FIG. 3, the eaves-mounting bracket 15 attaches the partition member 3 to the base metal piece 14, and then tightens means (screws, screws, etc.) F together with the partition member 3 with respect to the inclined piece 142 of the base metal piece 14. It is fixed by. In the present embodiment, the eaves hook mounting bracket 15 is a top-hanging type hardware. Specifically, the eaves rod mounting bracket 15 is configured to hook and hold the bent portions at the upper ends of the outer standing portion 42 and the inner standing portion 43 of the eaves rod 4. When the eaves hook mounting bracket 15 is employed as in the present embodiment, the eaves hook mounting bracket 15 is fixed to the inclined piece 142 of the base metal piece 14. In this case, the eaves bowl mounting bracket 15 is less likely to bend than the general housing in which the eaves bowl mounting bracket is mounted on the tip of the nose (vertical surface). ) The pulling force generated in F is reduced. However, the eaves hook mounting bracket 15 may be mounted on a vertical surface.

  Further, as shown in FIG. 1, in the present embodiment, the eaves cage 4 has an opening 44 that reaches the lower end of the outer standing portion 42 of the eaves cage 4. The opening 44 has a function of discharging rainwater collected in the eaves basket 4 to the outside. The required number of openings 44 is calculated based on the amount of precipitation, the area of the roof 2, the drainage capacity per opening 44, and the like. In particular, in the present embodiment, as shown in FIG. 1, a funnel 5 is connected to the opening 44 of the eaves basket 4, and a vertical fence 6 is connected to the outlet 5 a of the upper joint 5. Yes. If the opening 44 is formed in the outer upright portion 42 of the eaves ridge 4 as in the present embodiment, it is not necessary to connect the upper joint 5 to the bottom 41 of the eave ridge 4, and the lower side of the eave ridge 4 (the bottom 41 There is no need to secure space in the lower part. For this reason, like this embodiment, the height position of the whole eaves 4 can be made to approach the outer surface 3f of the partition material 3 (outer surface 32f of the 2nd piece 32). Therefore, according to the eaves surrounding structure of the building according to the present embodiment, the height position of the eaves cage 4 can be set to a lower position.

  Moreover, in this embodiment, since the thing which protrudes below the eaves basket 4 is not provided, the shape and accommodation of the partition material 3 can be simplified and unified. Further, in this specification, the “opening 44 of the outer standing portion 42 of the eaves cage 4” means an opening that penetrates the outer standing portion 42 of the eaves cage 4. The shape of the opening 44 is not limited as long as the opening 44 has a function of, for example, discharging rainwater collected inside the eaves fence 4 or guiding the rainwater to the vertical fence 6. . As a specific example of the opening 44, for example, in addition to a through hole formed in the outer standing portion 42 of the eaves cage 4 as in the present embodiment, the opening 44 is notched downward from the upper end of the outer standing portion 42 of the eaves cage 4. The part etc. are mentioned. The opening 44 preferably reaches the lower end 4e of the eaves bowl 4.

  In the present embodiment, the shape of the bottom 41 of the eaves basket 4 is a shape corresponding to the shape of the outer surface 3 f of the partition member 3. In the present embodiment, the shape of the bottom 41 of the eaves basket 4 is a shape corresponding to the outer surface 32 f of the second piece 32 of the partition member 3. In this case, the height position of the eaves ridge 4 can be made lower by bringing the second piece 32 of the partition member 3 and the bottom 41 of the eave ridge 4 close to each other. For this reason, if the shape of the bottom part 41 of the eaves basket 4 is made into the shape corresponding to the shape of the outer surface 3f of the partition material 3, the height position of the eaves bowl can be made into a lower position. In addition, when the load acting on the eaves ridge 4 increases due to heavy rain or snow and the eave ridge 4 is bent, the bottom 41 of the eave ridge 4 comes into contact with the second piece 32 of the partition member 3, thereby Can be prevented from increasing. Here, “adjacent” means not only the case where the gap C1 is formed between the second piece 32 of the partition member 3 and the bottom 41 of the eaves 4 as in the present embodiment, but also the partition member 3. This includes the case where the second piece 32 and the bottom 41 of the eaves 4 are in contact with each other. In this specification, “the shape of the bottom 41 of the eaves 4 is a shape corresponding to the shape of the outer surface 3 f of the partition member 3” means that the bottom 41 of the eaves 4 is connected to the outer surface 3 f of the partition 3. It means that it extends along. Specifically, the bottom 41 of the eaves basket 4 extends in parallel or substantially parallel to the second piece 32 of the partition member 3. Here, “substantially parallel” means that, for example, on the cross section, either one of the bottom 41 of the eaves 4 and the second piece 32 of the partition member 3 has a zigzag (unevenness) shape, and the other has a straight shape. This also includes the case where the straight line connecting the tops of the zigzag (unevenness) shape is parallel to the other. In addition, when both are zigzag (uneven) on the cross section, the case where the straight lines connecting the tops of the zigzag (uneven) shapes facing each other is parallel is also included. In the present embodiment, the bottom 41 of the eaves basket 4 is inclined at an inclination angle θ equal to the second piece 32 of the partition member 3 with respect to the horizontal plane. In the present embodiment, the bottom portion 41 of the eaves basket 4 has a shape corresponding to the shape of the outer surface 3 f of the partition member 3 by being inclined in parallel to the second piece 32 of the partition member 3. Yes. As described above, the second piece 32 of the partition member 3 and the bottom 41 of the eaves 4 are installed so as to be parallel to each other at the same inclination angle θ, for example, so that they are substantially parallel to each other. Even if the installation height of the eaves basket 4 is lowered as compared with the case where it is installed, a desired gap C1 can be secured.

  Further, in the present embodiment, the partition member 3 has a shape in which a portion corresponding to the bottom 41 of the eaves 4 is lowered downward from the eaves tip 2a side of the roof 2 toward the outer surface 1f side of the outer wall 1. In this case, it is possible to improve the water-stopping property because the rainwater that has flown around easily flows in the direction of the outer surface 1f of the outer wall 1, and it is also possible to prevent raindrops on the outer surface 1f of the outer wall 1 by preventing dust from accumulating. The antifouling property can be improved. Here, the shape of the roof 2 that is downwardly lowered from the eaves tip 2a side toward the outer surface 1f side of the outer wall 1 is a portion where the portion corresponding to the bottom 41 of the eaves 4 is flat as a whole, or a reverse gradient (horizontal The shape is such that there is no portion that becomes an upward gradient), and the inclination angle θ is greater than 0 degrees at any position. As a specific example, a cross-sectional shape that is convexly convex toward the inside of the building, a cross-sectional shape that is convexly convex toward the outside of the building, or the eaves portion 2a side of the roof 2 is directed to the outer surface 1f side of the outer wall 1. And a cross-sectional shape that is linearly lowered downward. In the present embodiment, the second piece 32 of the partition member 3 corresponds to a portion having a shape that descends downward from the eaves of the roof 2 toward the outer surface 1 f of the outer wall 1. In the present embodiment, the second piece 32 of the partition member 3 has a cross-sectional shape that linearly descends downward from the eaves of the roof 2 toward the outer surface 1 f of the outer wall 1. In addition, when the cross-sectional shape of the second piece 32 of the partition member 3 is not linear (for example, a wave shape or a zigzag shape), a flat portion or a valley portion where rainwater or dust may stay is formed. It is preferable that it is not.

  In addition, as shown in FIG. 3, in the present embodiment, the outer surface 42 f of the outer standing portion 42 of the eaves 4 is disposed at a horizontal position that protrudes further to the building exterior side than the outer surface 1 f of the outer wall 1. In this case, it is possible to prevent raindrops on the outer surface 1f of the outer wall 1 due to rainwater flowing down along the outer surface 42f of the outer standing portion 42 of the eaves wall 4.

  Also, as shown in FIG. 3, in this embodiment, the lower end 4e of the eaves ridge 4 has the horizontal outer edge of the bottom 41 of the eave ridge 4 facing the outside of the building at the lower end of the outer standing portion 41 of the eave ridge 4. The connection end is connected downward. In this case, when the building is looked up from below and a part of the bottom 41 of the eaves wall 4 protrudes from the outer surface 1f of the outer wall 1, the lower end (the lowest part) 4e of the eaves wall 4 is linear. Looks like it forms a ridgeline. For this reason, even when looking up at the building, a part of the bottom 41 of the eaves ridge 4 that protrudes outward in the horizontal direction from the outer surface 1f of the outer wall 1 does not feel the thickness, and the protrusion of the eave ridge 4 The feeling can be reduced. In the present embodiment, the horizontal position of the lower end 4e of the eaves ridge 4 protrudes slightly (15 mm) from the outer surface 1f of the outer wall 1, but the lower end 4e of the eave ridge 4 is bent at an acute angle, and a flat surface is formed. Since it does not form, it seems that there is no thickness visually, so the sense of protrusion is reduced. Note that the lower end 4e of the eaves ridge 4 has an acute angle between at least the lower end portion of the outer standing portion 41 of the eave ridge 4 and the horizontal outer edge portion of the bottom 41 of the eave ridge 4, and the connection end is As long as it constitutes a sharp edge, the shape of the other outer standing portion 41 of the eaves rod 4 and the bottom portion 41 of the eaves rod 4 can be appropriately changed in consideration of other conditions.

  Moreover, in this invention, the lower end 4e of the eaves basket 4 may be a height position which corresponds with the horizontal direction outer end 3e of the partition material 3, or a height position lower than the horizontal direction outer end 3e of the partition material 3. preferable. In this case, the partition member 3 is hidden behind the eaves 4 and is hardly visible from the outside. For this reason, it is not necessary to provide a separate cover for the partition member 3, and the configuration can be simplified. In particular, if the outer upright portion 42 of the eaves 4 is formed into a shape having excellent design properties, the design properties will not be impaired. In the present embodiment, the lower end 4 e of the eaves basket 4 is at a lower height position than the horizontal outer end 3 e of the partition member 3. In addition, when the horizontal direction outer side end 3e of the partition material 3 is not only the shape bent only like this embodiment, but the lower end 4e of the eaves basket 4 extends in the up-down direction, the partition material It is preferable that the height position coincides with the lower end of the horizontal outer end 3e of 3 or the lower height position than the lower end of the horizontal outer end 3e of the partition member 3.

  Further, in the present invention, the horizontal outer end 3e of the partition member 3 is in a horizontal position that coincides with the outer surface 1f of the outer wall 1 or a horizontal position that recedes toward the inside of the building from the outer surface 1f of the outer wall 1. It is preferable that they are arranged. In this case, coupled with the fact that the outer surface 42f of the outer standing portion 42 of the eaves ridge 4 is arranged at a horizontal position that protrudes to the outside of the building relative to the outer surface 1f of the outer wall 1, the partition material 3 is more reinforced. 4 is easy to hide. In this case, the partition material 3 is covered with the roof 2 and the eaves 4 so that rainwater and dust do not fall down on the partition material 3. For this reason, even if the partition member 3 is retracted from the outer surface 1 f of the outer wall 1, dirt does not adhere to the outer wall 1. In the present embodiment, the horizontal outer end 3 e of the partition member 3 is the outermost horizontal end of the partition member 3. Moreover, in this embodiment, the horizontal direction outer side edge 3e of the partition material 3 is set back from the outer surface 1f of the outer wall 1 toward the inside of the building.

  As described above, according to the present invention, it is possible to provide a structure around the eaves of the building that can lower the height of the eaves 4.

  The above is an example of various embodiments of the present invention, and various modifications can be made according to the description of the scope of claims. For example, as long as the partition member 3 has a shape having at least a second piece 32 that falls in the direction of the outer surface 1f of the outer wall 1 corresponding to the bottom 41 of the eaves wall 4, the shape of the other portions Can be appropriately changed according to the structure and use of the building (roof). The shape of the bottom 41 of the eaves 4 is not limited to the shape corresponding to the shape of the outer surface 3 f of the partition member 3. Moreover, when the shape of the bottom 41 corresponds to the shape of the outer surface 3f of the partition material 3, the eaves 4 can be brought close to the outer surface 3f of the partition 3 as described above. Therefore, it is effective for suppressing the height position of the eaves basket 4. Moreover, the external cross-sectional shape of the lower end 4e of the eaves ridge 4 of FIG. 3 can be a little rounded with a curvature radius within 2 to 3 mm, for example.
