Japanese Patent Laid-Open No. 10-61050

  However, the fixed edge described in Patent Document 1 is a long parting material integrally formed, and the supporting piece must be fixed to the trunk edge while being in contact with the eave ceiling and positioned. It was necessary to hold the long toe in a lifted state, and there was difficulty in workability.

  Further, since the vent hole is formed in the protruding piece so as to penetrate the vent groove, the exhaust direction is opposite to the air flow in the vent space between the wall base and the outer wall material, and the air is The exhaust space may stagnate, and the exhaust performance is not always sufficient.

  In addition, the ventilation groove conceals the ventilation hole, making it difficult to see the ventilation hole and preventing intrusion of rainwater and the like into the ventilation hole, but the stop edge is ahead of the front surface of the outer wall material by the ventilation groove. Since this protrusion protruded, the protrusion gave an uncomfortable feeling to the outer wall material, and the discomfort was not wiped out even by the presence of the decorative piece.

  The present invention has been made in view of the circumstances as described above, and has an object to provide a ventilation eaves ceiling parting edge having good workability and sufficient exhaust performance, and having a good construction appearance. .

  The ventilation eaves ceiling parting edge of the present invention is characterized by the following in order to solve the above problems.

  1stly, the base material which has a trunk edge fixing piece which hangs down from the rear end of a fitting convex part and a fitting convex part, and the outer wall material pressing piece and outer wall material pressing piece which can be arrange | positioned facing the trunk edge fixing piece of a base material A vent hole is formed in the upper part of the outer wall material pressing piece, and a vent hole is formed on the front side while forming a vent gap that opens upward. The louver covering further includes a cover material disposed on the front surface of the outer wall material pressing piece, and the cover material is fitted to the base material by fitting the fitting convex portion of the base material into the fitting concave portion of the cover material. .

  Second, in the first feature described above, an eaves ceiling contact piece extending toward the upper front side is provided at the upper end of the outer wall material pressing piece, and a watertight material is disposed on the upper surface of the eaves ceiling contact piece.

  According to the first aspect of the present invention, the ventilation part ceiling parting edge is not an integral object, but is divided into a base material and a cover material, and the base material fixed to the trunk edge by a fixing tool such as a nail or a screw is fitted. Since it is a member having a simple structure in which the trunk edge fixing piece hangs down from the rear end of the joint convex portion, even if it is long, the weight is relatively small, and fixing to the trunk edge is easy. Since the cover material is fitted to the base material by fitting the fitting convex portion of the base material into the fitting concave portion, the cover material can be attached by a so-called one-touch type, and the weight of the cover material is also increased. Since the base material is reduced, the cover material can be easily attached. By fitting the cover material to the base material, the upper end portion of the outer wall material arranged near the eaves ceiling is received. Therefore, the workability of the ventilation eaves ceiling parting edge is good.

  Further, the vent hole is formed by penetrating front and rear in a portion above the fitting recess of the outer wall material pressing piece of the cover material, and a louver covering the vent hole from the front while forming a vent gap opening upward is an outer wall material. Since it is arranged on the front surface of the holding piece, the exhaust direction is easy to follow the air flow in the ventilation space between the wall base and the outer wall material, and the air can be discharged almost straight outdoors. There is almost no stagnation and exhaust performance is sufficiently high. In addition, since the outer wall material pressing piece that can be disposed opposite to the body edge fixing piece of the base material can be formed in a substantially flat shape, it is substantially along the front surface of the outer wall material after construction and does not give a sense of incongruity. Although a louver covering the vent hole from the front is visually recognized, the size and shape of the louver can be appropriately designed corresponding to the vent hole, and is not conspicuous. Therefore, the construction appearance of the ventilation eaves ceiling parting edge is good.

  According to the second aspect of the invention, the watertightness between the eaves eave ceiling parting edge eaves ceiling is the watertightness provided on the upper surface of the eaves ceiling abutting piece extending toward the upper front side at the upper end of the outer wall material pressing piece. Sufficiently secured by the material. Sealing between the ceiling and the eaves can be eliminated, and the workability is improved.

  FIG. 1 is a perspective exploded view of a main part showing an embodiment of a ventilation eaves ceiling parting edge of the present invention.

  The ventilation eaves ceiling parting edge 1 shown in FIG. 1 is arranged in the vertical direction on the wall base, spans between a plurality of trunk edges that form a ventilation space with the outer wall material, and is fixed to the trunk edge. The base material 2 and the cover material 3 that can be fitted to the base material 2 are divided.

  The base material 2 includes a fitting convex portion 4 and a trunk edge fixing piece 5 that hangs down from the rear end of the fitting convex portion 4, and is formed by bending a single metal thin plate 6. The fitting convex portion 4 includes a first horizontal piece 7 made of a thin metal plate 6, and a first thin piece 6 that is bent at the front end of the first horizontal piece 7 toward the rear lower side and forms an acute angle with the first horizontal piece 7. The inclined piece 8 is formed. The thin metal plate 6 is folded back to the upper front side at the rear end of the first inclined piece 8 and is folded on the upper surface of the first inclined piece 8. The rigidity of the fitting convex portion 4 is increased by folding the thin metal plate 6 in the first inclined piece 8.

  The trunk edge fixing piece 5 is formed by bending a thin metal plate 6 at a right angle toward the lower side at the rear end of the first horizontal piece 7 forming the fitting convex portion 4. The metal thin plate 6 is folded forward and upward at the lower end of the trunk edge fixing piece 5 and is folded on the front surface of the trunk edge fixing piece 5. The rigidity of the trunk edge fixing piece 5 is increased by folding the thin metal plate 6.

  Thus, the base material 2 formed by bending the single metal thin plate 6 has rigidity, and can sufficiently be used as a long member spanned between a plurality of body edges. It is done. Examples of the metal thin plate 6 include a steel plate and an aluminum plate having a thickness that can be easily bent.

  The cover material 3 has a main body 9 with an outer wall material pressing piece 10 that can be disposed opposite to the trunk edge fixing piece 5 of the base material 2, and a fitting recess 11 that is disposed behind the outer wall material pressing piece 10. Moreover, it has the eaves ceiling contact piece 12 extended toward the front upper side at the upper end of the outer wall material pressing piece 10. The main body 9 of the cover material 3 is also formed from a single metal thin plate 13 by bending.

  The thin metal plate 13 is bent toward the front upper side at the upper end of the outer wall material pressing piece 10, folded back at the front end of the eaves ceiling contact piece 12, and the eaves ceiling contact piece 12 is folded up and down. 13. The folded metal thin plate 13 is folded at the lower end of the eaves ceiling contact piece 12 and is folded on the rear surface of the outer wall material pressing piece 10.

  The thin metal plate 13 folded on the rear surface of the outer wall material pressing piece 10 is bent at a right angle toward the rear of the outer wall material pressing piece 10 near the center of the vertical width of the outer wall material pressing piece 10, and the second horizontal piece 14 is formed. Forming. The thin metal plate 13 is folded forward and downward at the rear end of the second horizontal piece 14 to form a third horizontal piece 15. The third horizontal piece 15 is folded on the lower surface of the second horizontal piece 14, and the third horizontal piece 15 is folded. The front end of the horizontal piece 15 is disposed near the front end of the second horizontal piece 14. The length of the third horizontal piece 15 in the main body 9 in the front-rear direction corresponds to the length of the first horizontal piece 7 in the base material 2 in the front-rear direction, and is slightly longer than the length of the first horizontal piece 7 in the front-rear direction. is doing.

  At the front end of the third horizontal piece 15, the metal thin plate 6 is bent rearward and downward to form a second inclined piece 16 that forms an acute angle with the third horizontal piece 15. The front end of the second inclined piece 16 is disposed in the vicinity of the front ends of the second horizontal piece 14 and the third horizontal piece 15 formed by folding the thin metal plate 13. The fitting recess 11 is formed between the third horizontal piece 15 and the second inclined piece 16. The angle formed between the third horizontal piece 15 and the second inclined piece 16 is slightly smaller than the angle formed between the first horizontal piece 7 and the first inclined piece 8 forming the fitting convex portion 4 of the base material 2. . At the front end of the second inclined piece 16, the metal thin plate 13 is folded back to the upper front side, is folded back to the lower rear side again, and is folded on the rear end portion of the second inclined piece 16.

  Further, the metal thin plate 13 is bent obliquely rearwardly and downwardly at the lower end portion of the outer wall material pressing piece 10 and further bent obliquely rearwardly upward and protrudes rearward from the lower end portion of the outer wall material pressing piece 10. A portion 17 is formed. The rearward protrusion margin of the outer wall material abutting portion 17 is sufficiently smaller than the length of the third horizontal piece 15 in the front-rear direction.

  As described above, the cover material 3 on which the main body 9 is formed by bending the single metal thin plate 13 has sufficient rigidity similarly to the base material 2 and can be sufficiently used as a long member. .

  In the cover material 3, a vent hole 18 penetrating back and forth is formed in a portion of the outer wall material pressing piece 10 above the fitting recess 11, and a louver 19 that covers the vent hole 18 from the front is formed on the front surface of the outer wall material pressing piece 10. It is arranged. FIG. 2 is a perspective view of a main part when the periphery of the louver 19 is viewed from the front of the cover member 3.

  As shown in FIG. 1, in the main body 9 formed by bending a single metal thin plate 13, the portion of the outer wall material pressing piece 10 corresponding to the formation portion of the vent hole 18, that is, above the second horizontal piece 14. In this portion, the metal thin plate 13 is folded back and forth, so that the air holes 18 are formed in the rear metal thin plate 13 by punching. The louver 19 is a portion of the thin metal plate 13 that has a cut 21 in the lateral direction slightly above the upper edge 20 corresponding to the upper edge 20 of the air hole 18 in the thin metal plate 13 on the front side. It is formed by pushing forward. As shown in FIG. 2, the louver 19 has a substantially rectangular opening 22 on the upper side, and covers the front of the vent hole 18 while forming a vent gap 23. The ventilation gap 23 communicates with the ventilation hole 18. Since the vent hole 18 is concealed by the louver 19 and the opening 22 opens upward, neither the vent 18 nor the opening 22 is visible when the cover material 3 is looked up from below. Further, the louver 19 prevents rainwater and the like from entering the vent hole 18 and the invasion of pests and small animals.

  Examples of the thin metal plate 13 forming the main body 9 of the cover material 3 include a steel plate and an aluminum plate having a thickness that can be easily bent, punched and cut.

  Further, as shown in FIGS. 1 and 2, the cover member 3 is provided with a watertight member 24 on the upper surface of the eaves ceiling contact piece 12 of the main body 9. The watertight material 24 is for pressing the eaves ceiling to ensure watertightness, and is formed from an elastic material such as rubber or soft resin. The watertight material 24 may be a foam 26 having a large number of pores 25.

  Such a cover material 3 can be fitted to the base material 2 as shown in FIG. That is, the cover material 3 is fitted to the base material 2 by fitting the fitting convex portion 4 of the base material 2 into the fitting concave portion 11 of the cover material 3. When the fitting convex portion 4 is inserted into the fitting concave portion 11, the angle formed by the third horizontal piece 15 forming the fitting concave portion 11 and the second inclined piece 16 forms the first horizontal piece 7 forming the fitting convex portion 4. And the first inclined piece 8 is slightly smaller than the angle between the first inclined piece 8 and the fitting convex part 4 so as to push the fitting concave part 11 wide, and the length in the front-rear direction of the third horizontal piece 15 is the first horizontal. Since the length of the piece 7 is slightly longer than the length in the front-rear direction, the fitting projection 4 fits into the fitting recess 11 before the front end of the fitting projection 4 reaches the inside of the fitting recess 11. Since both the base material 2 and the main body 9 of the cover material 3 are formed from the thin metal plates 6 and 13, the fitting of the fitting convex portion 4 to the fitting concave portion 11 is elastic. Therefore, the cover material 3 can be firmly fitted to the base material 2 and is fixed to the base material 2 with sufficient fixing strength.

  When the ventilation eaves ceiling parting edge 1 divided into the base material 2 and the cover material 3 as described above is constructed and the upper end portion of the outer wall material arranged near the eaves ceiling is put down, first, FIG. As shown in a>, the cover material 3 is attached to a portion corresponding to the upper end portion of the outer wall material at the upper end portion of the trunk edge 29 disposed on the wall base 28 extending from the base side to the eaves ceiling 27, and a screw. It fixes using the fixing tools 30, such as. The cover member 3 is positioned corresponding to the upper end portion of the outer wall member, is spanned between the plurality of trunk edges 29, and is fixed by contacting the trunk edge fixing piece 5 to the trunk edge 29. A through-hole penetrating in the front-rear direction can be formed in the trunk edge fixing piece 5 in advance depending on the material of the metal thin plate 6 and the type of the fixture 30. The formation of the through hole can also be performed when the cover material 2 is manufactured.

  In addition, since an outer wall material may be arrange | positioned on the existing wall and an outer wall may be reformed, the wall base 28 in which the trunk edge 29 is arrange | positioned is a wall base in which a moisture-permeable waterproof sheet is arrange | positioned on the outermost surface. In addition to existing walls.

  Next, as shown in FIG. 3 <b>, an outer wall material 31 having an upper end disposed near the eaves ceiling 27 is attached. At this time, the fitting convex part 4 of the base material 2 is located slightly above the upper end of the outer wall material 31 and enables fitting with the fitting concave part 11 of the cover material 3 shown in FIG. That is, the first inclined piece 8 is the outer wall material so that the second inclined piece 16 forming the fitting concave portion 11 can enter between the first inclined piece 8 forming the fitting convex portion 4 and the upper end of the outer wall material 31. It is located away from the upper end of 31.

  Then, as shown in FIG. 3 <c>, the cover member 3 is fitted to the base member 2 fixed to the trunk edge 29 from the front of the outer wall member 31. As described above, the fitting is realized by elastic fitting between the fitting concave portion 11 of the cover material 3 and the fitting convex portion 4 of the base material 2, and the third horizontal piece 15 forming the fitting concave portion 11 is provided. The second inclined piece 16 is in close contact with the first inclined piece 8 between the upper end of the outer wall material 31 and the cover material 3 is attached to the base material 2. It is firmly fixed. At this time, the outer wall material pressing piece 10 of the cover material 3 contacts the upper end surface of the outer wall material 31 at the outer wall material contact portion 17 at the lower end, and presses the upper end portion of the outer wall material 31 rearward. The upper end of the is covered from the front. For this reason, the fixing tool 30 which fixes the base material 2 to the trunk edge 29 is concealed. In addition, the eaves ceiling contact piece 12 at the upper end of the outer wall material pressing piece 10 contacts the eaves ceiling 27, and the watertight material 24 disposed on the upper surface of the eaves ceiling contact piece 12 presses against the eaves ceiling 27. The ventilation eaves ceiling parting edge 1 is installed as a parting material between the upper end part of the outer wall material 31 and the eaves ceiling 27 with the upper end part of the outer wall material 31 disposed near the eaves ceiling 27 being completed. .

  As described above, the ventilation eaves ceiling parting edge 1 is not an integral part, but is divided into the base material 2 and the cover material 3, and the base material 2 fixed to the trunk edge 29 by the fixing tool 30 is the fitting convex portion 4. Since it is a member having a simple structure in which the trunk edge fixing piece 5 hangs down from the rear end, even if it is long, the weight is relatively small, and fixing to the trunk edge 29 is easy. Since the cover material 3 is fitted to the base material 2 by fitting the fitting convex portion 4 of the base material 2 to the fitting concave portion 11, the cover material 3 can be attached by a so-called one-touch type. Since the weight of the cover material 3 is reduced by the base material 2, the cover material 3 can be easily attached. Therefore, the workability of the ventilation eaves ceiling parting edge 1 is good.

  Further, as shown in FIGS. 1 and 2, the air hole 18 is formed through the front and rear in a portion above the fitting recess 11 of the outer wall material pressing piece 10 of the cover material 3 and opens upward. Since the louver 19 that covers the ventilation hole 18 from the front while forming the ventilation gap 23 having the portion 22 is disposed on the front surface of the outer wall material pressing piece 10, as shown in FIG. It is easy to follow the flow of air in the ventilation space 32 formed between the wall base 28 and the outer wall material 31, and the air can be exhausted outdoors almost straight. The air flowing through the ventilation space 32 from the base side toward the eaves ceiling 27 side flows into the exhaust space 33 formed between the eaves ceiling 27 and the second horizontal piece 14 of the cover material 3 and then flows in the same direction. Without changing, the air flows toward the ventilation hole 18 and flows out to the ventilation gap 23 formed by the louver 19, and is exhausted to the outside through the opening 22 at the upper end of the ventilation gap 23. Therefore, the air is surely exhausted without stagnation in the exhaust space 33. The exhaust performance of the ventilation eaves ceiling parting edge 1 is sufficiently high.

  In addition, since the outer wall material pressing piece 10 that can be disposed opposite the trunk edge fixing piece 5 of the base material 2 at the ventilation eaves ceiling parting edge 1 can be formed in a substantially flat shape, it is shown in FIG. Thus, after construction, it almost follows the front surface of the outer wall material 31 and does not give a sense of incongruity. Although the louver 19 which covers the vent hole 18 from the front is visually recognized, the size and shape of the louver 19 can be appropriately designed corresponding to the vent hole 18 and are not conspicuous. As shown in FIG. 1 and FIG. 2, a plurality of vent holes 18 can be arranged at regular intervals along the longitudinal direction of the outer wall material pressing piece 10 of the cover material 3. Even so, the length is sufficiently smaller than the entire length of the outer wall material pressing piece 10 in the longitudinal direction, and the protruding margin of the louver 19 protruding forward of the outer wall material pressing piece 10 can be made sufficiently small. No. 19 is not conspicuous and does not give an uncomfortable appearance. Therefore, the construction appearance of the ventilation eaves ceiling parting edge 1 is good. Further, when the outer wall material 31 is a metal-based outer wall material formed by sandwiching a core material between a metal surface material and a back surface material, the material of the metal thin plate 13 forming the main body 9 of the cover material 3 is made of metal. It can be combined with the material of the surface material of the system outer wall material, and an appearance with a high unity feeling can be obtained. As the outer wall material 31, an inorganic outer wall material such as a cement plate can be used in addition to a metal outer wall material.

  Further, as shown in FIG. 3 <c>, the watertightness between the ventilation eaves ceiling parting edge 1 and the eaves ceiling 27 is arranged on the upper surface of the eaves ceiling contact piece 12 at the upper end of the outer wall material pressing piece 10. It is sufficiently secured by the watertight material 24. Sealing between the eaves ceiling 27 can be eliminated, and the workability is improved.

  Water tightness with the outer wall material 31 of the ventilation eaves ceiling parting edge 1 can be ensured at the outer wall material abutting portion 17 at the lower end portion of the outer wall material pressing piece 10. A gap 35 between a portion 34 on the rear side on the rear side of the outer wall material abutting portion 17 and the upper surface of the outer wall material 31 is filled with a sealing material as needed, and the outer wall of the ventilation eaves ceiling parting edge 1 The water tightness with the material 31 can be enhanced. Even if the sealing material is filled, it is concealed by the portion 34 toward the rear oblique upper side on the rear side of the outer wall material abutting portion 17, so that the appearance is maintained well.
