It is sectional drawing which illustrated the attachment state of the eaves ceiling parting edge of this invention. It is sectional drawing which illustrated the form of the conventional eaves ceiling parting edge.

  FIG. 1 is an exploded perspective view illustrating an embodiment of an eaves ceiling parting edge according to the present invention.

  The eaves ceiling parting edge 1 has a base material 2 and a cover material 3. The base material 2 and the cover material 3 are both long members along the building outer wall. Examples of the material include a metal thin plate such as an iron plate, an aluminum plate, a copper plate, a stainless steel plate, a titanium plate, an aluminum / zinc alloy plated steel plate, or a synthetic resin plate such as a vinyl chloride resin plate and a polycarbonate resin plate. Both the base material 2 and the cover material 3 can be manufactured, for example, by bending a single metal thin plate. Thereby, processing cost and labor can be suppressed.

  The base material 2 has a vertical plate 4 and a protruding piece 5. The lower end portion of the vertical plate 4 is folded to form a lower end folded portion 4a. Further, the upper end portion of the vertical plate 4 is also folded to form an upper end folded portion 4b. The lower end folded portion 4a and the upper end folded portion 4b can be formed as necessary.

  The vertical plate 4 is provided with an elliptical air hole 6 penetrating the upper end folded portion 4b at the upper end. The shape, number, etc. of the air holes 6 can be designed as appropriate.

  Further, the vertical plate 4 is provided with a protruding piece 5 protruding in the horizontal direction from the end of the upper end folded portion 4b. The length of the protruding piece 5 can be appropriately designed in consideration of the bonding strength with the cover material 3 and the like. For example, the length can be approximately the same as the thickness of the exterior material (not shown). At the tip of the protruding piece 5, a claw portion 7 is provided that bends in an obliquely downward direction on the vertical plate 4 side. The shape, length, and bending angle of the claw portion 7 can be designed as appropriate.

  The cover material 3 is substantially L-shaped, and has a substantially vertical decorative piece 8 and an engaging piece 9 extending in the rear horizontal direction from the upper end of the decorative piece 8. Here, the “rear” means a trunk edge direction after construction, and in FIG. 1, a direction facing the base material 2. Then, the lower end of the decorative piece 8 is folded and provided with a bent portion 8a.

  The engagement piece 9 has a horizontal upper piece 10 and a lower piece 11 extending from the lower surface of the upper piece 10 toward the obliquely downward direction of the tip. An engagement folded portion 12 that is folded upward is provided at the tip of the lower piece 11.

  2A to 2C are enlarged schematic views illustrating a process of attaching a cover material to a base material at an eaves ceiling parting edge in the form illustrated in FIG.

  The structure of the engagement piece 9 of the cover material 3 and the mounting method of the cover material 3 will be described in detail with reference to FIG.

  As illustrated in FIG. 2A, the upper piece 10 of the engagement piece 9 extends in the horizontal direction from the upper end of the decorative piece 8, is folded downward at the distal end portion 10a, and extends again to the decorative piece 8 side. . Therefore, the upper piece 10 is formed by overlapping two layers of plate-like members having a hairpin structure at the tip portion 10a.

  Further, a lower piece 11 is extended from the end of the upper piece 10 extending toward the decorative piece 8 toward the tip obliquely downward. Therefore, a space X is formed between the upper piece 10 and the lower piece 11 so as to expand in the distal direction. The angle between the upper piece 10 and the lower piece 11 is designed to be smaller than the bending angle of the claw portion 7 at the tip of the protruding piece 5 of the base material 2. The length of the upper piece 10 is designed to be longer than the length of the protruding piece 5 of the base material 2. An engagement folded portion 12 that is folded upward is provided at the tip of the lower piece 11.

  On the other hand, as described above, the claw portion 7 that bends in the diagonally downward direction on the vertical plate 4 side is provided at the tip of the protruding piece 5 extending from the upper end folded portion 4b.

  When the cover material 3 is attached to the base material 2, the protruding piece 5 of the base material 2 enters the space X of the engagement piece 9 of the cover material 3 as illustrated in FIG. The cover material 3 is pushed in from the front. As a result, the lower piece 11 of the engagement piece 9 is pushed in while being pushed downward (in the direction of the arrow in the figure) along the inclination of the claw portion 7 at the tip of the protruding piece 5. Since the upper piece 10 and the lower piece 11 have the above-described structure, an elastic force is exerted. Therefore, even if the lower piece 11 is pushed and spread, there is no possibility that the engagement piece 9 is damaged.

  Then, as illustrated in FIG. 2C, when the cover member 3 is pushed in, the distal end portion 10 a of the upper piece 10 of the engagement piece 9 substantially contacts the upper end folded portion 4 b of the base member 2. At this time, the engaging folded portion 12 at the tip of the lower piece 11 of the engaging piece 9 reaches the tip 7 a of the claw portion 7 of the protruding piece 5. Then, due to the elastic force of the upper piece 10 and the lower piece 11, the engagement folded portion 12 at the tip of the lower piece 11 slides to the protruding piece 5 side, and the lower piece 11 pushed and spread downward is directed upward (in the direction of the arrow in the figure). Return. As a result, the distal end portion 12 a of the engagement folded portion 12 of the engagement piece 9 is engaged with the distal end portion 7 a of the claw portion 7 of the protruding piece 5. Therefore, the base material 2 and the cover material 3 can be mounted and integrated simply and reliably by simply pushing the cover material 3 into the base material 2 from the front.

  FIG. 3 is a cross-sectional view illustrating an attachment state of an eaves ceiling parting edge according to the present invention.

  The eaves ceiling parting edge 1 is disposed between the eaves ceiling 21 and the upper end of the exterior material 22. The base material 2 has an upper end in contact with the eaves ceiling 21, and the back surface of the vertical plate 4 faces the rear trunk edge 23. The vertical plate 4 is fixed by a fixing member 13 at a position below the protruding piece 5 of the base material 2. The fixing member 13 passes through the trunk edge 23 and reaches the wall base 14. Further, the base material 2 includes a vent hole 6 in the upper end folded portion 4b. For this reason, for example, as indicated by arrows in the figure, air flows through the vent hole 6 between the inside of the trunk edge 23 and the outside of the eaves ceiling parting edge 1. By providing the vent hole 6 in the vertical plate 4, wind can easily enter from the outside, and high air permeability is ensured. For this reason, moist air does not accumulate in the trunk edge 23, and corrosion of the trunk edge 23, generation of mold, and the like can be effectively suppressed. In addition, an insect repellent net or the like can be appropriately provided in the vent hole 6.

  Furthermore, the exterior member 22 is disposed below the protruding piece 5 so as to face the vertical plate 4, and the upper end is fixed by the fixing member 15 via the vertical plate 4. The fixing member 15 also reaches the wall base 14 through the trunk edge 23. Therefore, the fixing member 13 for fixing the vertical plate 4 is located on the back side of the exterior material 22. Further, a gap is generated between the exterior material 22 and the vertical plate 4 by the lower end folded portion 4 a of the vertical plate 4 of the base material 2.

  The engaging piece 9 of the cover material 3 is engaged with the protruding piece 5 of the base material 2 by the engaging structure described with reference to FIG. By simply pushing the cover material 3 into the fixed base material 2 from the front, the base material 2 and the cover material 3 can be mounted and integrated easily and reliably.

  When the cover material 3 is attached to the base material 2, the exterior material 22 is sandwiched between the vertical plate 4 of the base material 2 and the decorative piece 8 of the cover material 3. The length of the protruding piece 5 of the base material 2 and the engaging piece 9 of the cover material 3 can be designed in accordance with the thickness of the exterior material 22. Further, the bent portion 8 a at the lower end of the decorative piece 8 is in contact with the surface of the exterior material 22. Thereby, invasion of insects or the like into the cover material 3 can be suppressed. The bent portion 8 a at the lower end of the decorative piece 8 can be adjusted at the time of construction in consideration of the thickness of the exterior material 22.

  The upper end of the exterior material 22 and the head 15 a of the fixing member 15 that fixes the exterior material 22 are covered from the outside by the decorative piece 8 of the cover material 3. Therefore, since neither the head 13a of the fixing member 13 that fixes the vertical plate 4 nor the head 15a of the fixing member 15 that fixes the exterior material 22 is exposed to the outside, the eaves-ceiling parting edge 1 after the construction is improved in design. Are better.

  Furthermore, since the eaves ceiling parting edge 1 is constituted by the base material 2 and the cover material 3 to be engaged, the vertical plate 4 of the base material 2 can be fixed without exposing to the outside. For this reason, the appearance width L of the eaves ceiling parting edge 1 is the length L1 of the vertical plate 4 (upper end folding portion 4b) above the protruding piece 5 of the base material 2 and the length L2 of the decorative piece 8 of the cover material 3. The sum of Therefore, the eaves ceiling parting edge 1 can reduce the external width L as compared with the conventional case, is not easily noticeable, and the external design is favorably maintained.

  Further, a waterproof material 16 is disposed at a joint portion between the base member 2 and the cover member 3, that is, at a contact portion between the distal end portion 10 a of the upper piece 10 of the engagement piece 9 and the upper end folded portion 4 b of the base member 2. Has been. When rainwater enters from the joint, rainwater may flow along the engagement pieces 9 of the cover material 3 and stay between the exterior material 22 and the trunk edge 23. Therefore, by disposing the waterproof material 16 at the joint location, corrosion of the exterior material 22 and the trunk edge 23 due to moisture, generation of mold, and the like can be suppressed. A conventionally known material can be used as the waterproof material 16. For example, silicone-based, polyurethane-based (reaction-curing type / moisture-curing type), and acrylic-based packing materials can be exemplified.

  In addition, the eaves ceiling parting edge of this invention, and its attachment structure are not limited to said embodiment. For example, a waterproof material can be provided between the eaves ceiling and the eaves ceiling parting edge. Moreover, the folding process of each part of a base material and a cover material is not necessarily required. For example, when the upper end folding portion is not provided on the vertical plate, the projecting piece can be extended in the horizontal direction from the front surface of the vertical plate at a position below the vent hole.
