  The above utility model registration No. 3046176 is an L-angle shaped member made of an extruded product of a synthetic resin and having a uniform non-porous plate-like body intersected at a substantially right angle. The thickness of the protruding corner material is uniform as a whole.

  When such a conventional protruding corner material is attached to the protruding corner with double-sided tape and coated with a putty, the mounting of the protruding corner member to the base plate tends to deteriorate over time. In addition, when there is a change in the base plate due to expansion of the building frame or the like, cracks are likely to occur in the putty along the edges of the protruding corner material.

  The present invention eliminates such problems of the prior art, can be firmly attached to the base plate, and can prevent the coating material from cracking, and the corner corner material It is an object to provide a protruding corner structure using.

  The projected corner material of the present invention is a projected corner material having a pair of long plate-like bodies whose longitudinal sides intersect at a substantially right angle. This hole is provided, and the vicinity of the crossing side is a non-hole area where the hole does not exist.

  The projecting corner structure of the present invention attaches the projecting corner material of the present invention to the projecting corner where the base plates are butted together, and covers the butted portion of the base plates in the non-hole region of the projecting corner material, The coating material is applied so that this corner material can be applied.

  In the present invention, the crossing angle of the plate-like body is preferably smaller than 90 °.

  Moreover, it is preferable that the plate | board thickness becomes small so that the edge side of at least the edge side of a plate-shaped body is near.

When this projecting corner material is attached to the projecting corner and applied with a coating material, the coating material adheres directly to the base plate through the holes, so that the mounting of the projecting corner material becomes strong for a long time.

  It should be noted that the amount of the coating material entering the hole is smaller than that in the case where the hole is provided in the entire protruding corner material.

  Further, in the projected corner structure in which the projected corner material is attached to the projected corner where the base plates are butted together, the butted portion is covered with a non-porous region of the projected corner material. Therefore, the level difference of the butt portion does not affect the finished surface.

  In the case where the crossing angle between the plate-like bodies is smaller than 90 °, there is a slight space between the base plate and the crossing side portion of the protruding corner material and the back surface in the vicinity thereof. Therefore, even if the base plate moves or the sealing material between the base plates moves following the base plate so as to protrude from the base plate, this movement is accommodated in the space and does not affect the finished surface.

  When the portion near the edge of the corner of the protruding corner is made thinner as it approaches the edge, the coating material applied so that the corner of the protruding corner can be applied should be The occurrence of cuts and steps can be eliminated or suppressed, and the aesthetics of the finished surface can be improved.

  Hereinafter, embodiments will be described with reference to the drawings.

  FIG. 1 is a perspective view of a projected corner material according to the embodiment, FIG. 2 (a) is a side view thereof, FIG. 2 (b) is a sectional view thereof, and FIG. 3 is a projected corner according to the embodiment. It is a perspective view of a structure.

  In FIG. 1, a protruding corner material 1 is a long L-shaped member having plate-like bodies 2 and 2 that intersect at a substantially right angle. The protruding corner material 1 has a symmetrical shape with the intersecting sides of the plate-like bodies 2 and 2 interposed therebetween. The protruding corner material 1 is made of a synthetic resin or a corrosion-resistant metal material.

The length of the protruding corner material 1 is preferably about 1 to 4 m, particularly about 2 to 3 m. The width W ₁ of the plate-like body 2 is suitably 20 to 90 mm, particularly 30 to 60 mm.

A large number of holes 3 are provided in the vicinity of the end opposite to the crossing side of each plate-like body 2. The hole 3 is preferably circular, but is not limited thereto. The opening area of the hole 2 is suitably 5 to 100 mm ^2, especially 10 to 20 mm ² approximately. When the hole 2 is circular, its diameter is preferably about 2 to 10 mm, particularly about 3 to 5 mm.

In this embodiment, the hole 3 is provided in a range from an end edge of the distance W ₂ of each plate-like body. The range of the distance W ₃ from the crossing side is a non-porous region where the hole 3 is not provided. Note that W ₂ + W ₃ = W ₁ . The value of W ₂ / W ₁ × 100% is preferably 10 to 70%, particularly preferably 20 to 40%.

In the perforated region _{W 2,} each hole 3 next to the aperture ratio of the organic hole area _{W 2} is 30 to 75%, also the aperture ratio is 300 mm ² / ^{m 2} or more, particularly 3000 mm ² / ^{m 2} or more and It is preferable to be provided.

  The crossing angle θ of the plate-like bodies 2 and 2 is preferably 90 ° or less, particularly 89 ° to 90 °.

The thickness of the plate-like body 2, the end side near, preferably has a thin enough end side at least the perforated region W _2.

  The thickness of the end side of the plate-like body 2 is preferably about 0.6 mm or less, and is preferably 1 mm or less near the crossing side.

Further, the crossing portions of the plate-like bodies 2 and 2 have protrusions 21. Since the protrusion 21 can clearly show the corner line of the protruding corner, it has a beautiful finish. The height W ₄ is about 2mm of the projection 21, preferably 1.8 mm, coating material may issue a more clean corners Workup in accordance with the projecting tip portion.

  Next, a protruding corner structure using the protruding corner material 1 will be described with reference to FIG.

  A moisture-permeable waterproof sheet 11 is stretched along a pair of outward faces of the pillar 10 erected at the protruding corner. Vertical trunk edges 12 and 13 are superimposed on the upper side of the moisture permeable waterproof sheet 11 so as to overlap the pair of outward faces of the pillar 10 and are fastened to the pillar 10 with nails (not shown) or the like. Yes. The vertical trunk edges 12 and 13 are abutted so as to have an L shape. In this embodiment, the wood end surface of the front end portion on the corner side of the vertical body edge 13 is abutted against the back surface of the front end portion on the corner side of the vertical body edge 12.

  The base plates 15 and 16 are overlapped with the vertical body edges 12 and 13, and the base plates 15 and 16 are fixed to the column 10 by the nails 17. The nail 17 is driven into the column 10 through the longitudinal body edges 12 and 13.

  A single hat joiner 18 is interposed between the base plate 15 that overlaps the vertical body edge 12 and the vertical body edge 12. The single hat joiner 18 is a long member having a cross-sectional shape (single hat shape) having a U-shaped portion 18a and a thin flat plate portion 18b extending from the U-shaped portion 18a.

  The base plates 15 and 16 are attached so that the wood end surface of the corner side of the base plate 15 abuts the back surface of the corner side tip portion of the base plate 16 through the U-shaped portion 18a of the one-side hat joiner 18. The flat hat portion 18 b of the one-hat joiner 18 is sandwiched between the base plate 15 and the vertical trunk edge 12. The U-shaped portion 18 a is sized to enter a predetermined depth from the back surface of the base plate 15 between the wood end surface of the base plate 15 and the back surface of the base plate 16.

  A sealing 19 is filled in a vertical jointed groove surrounded by the U-shaped portion 18 a and the base plates 15 and 16.

  The projecting corner material 1 is overlapped with the projecting corner where the base plates 15 and 16 are abutted, and the projecting corner material 1 is fixed to the base plates 15 and 16 by applying the sealing 20.

The protruding corner material has such a size that the non-porous region W ₃ covers the sealing 19. Specifically, it is 20 mm or more. On the base plate 15 side, the perforated region W ₂ overlaps only the base plate 15, and the hole 3 does not face the sealing 19.

The sealing 20 comprises at least the perforated region W _2, it is Nurigi to cover the region along the external corner corner member 1 of the base plates 15 and 16. The sealing 20 applied on the corner material 1 adheres to the base plates 15 and 16 through the holes 3. Thereby, the sealing 20 functions as an anchor for fixing the protruding corner material 1, and the protruding corner material 1 is firmly attached to the base plates 15 and 16 over a long period of time.

  Next, an undercoat (undercoating material) 22 is applied, and a topcoat (coating finish) 23 is further applied thereon. The undercoat 22 and the topcoat 23 are coated so as to cover the entire surface of the sealing 20, the corner corner material 1, and the base plates 15 and 16.

  The undercoat 22 can be a resin system or a cement system, and the top coat 23 can be a resin system or a cement system, but the material is not limited to this.

  In the projecting corner structure finished in this way, as described above, the sealing 20 is directly attached to the base plates 15 and 16 through the hole 3, and the projecting corner corner is formed by the anchor effect of the sealing 20. The material 1 can be firmly fixed to the base plates 15 and 16 over a long period of time.

  Various coating materials such as resin and cement-based materials can be used.

Further, the hole 3 is therefore provided only in the perforated area W _2, it requires less the coating amount of the sealing 20 in comparison with the case of providing the hole 3 in the whole area of the plate-like body 2.

  In addition, since the protruding corner material 1 is symmetrical, it can be used without any problem even if it is turned upside down during construction.

  Since the intersection corner material 1 has a crossing angle θ smaller than 90 °, a slight space is formed between the corner of the base plate 15 in the vicinity of the intersection side of the corner corner material 1. For this reason, even if the ceiling 19 slightly protrudes from the surface of the base plate 15 due to the movement of the base plates 15 and 16, the protrusion is absorbed in the space, and the finished surface is not affected.

The external corner corner material 1, since the non-porous region W ₃ covers the ceiling 19 of the plates, impact at all on the finished surface and the sealing 19 is lean beyond.

  Further, since the protruding body corner material 1 has a thin plate-like body 2 facing the end side, even when it is thinly coated especially like a coating material, it extends along the end side of the plate-like body 2. It is possible to prevent streaks and cuts from occurring on the finished surface. That is, it is possible to obtain a beautiful finished surface where the boundary between the protruding corner material 1 and the base plates 15 and 16 is not conspicuous.

It is a lineblock diagram of a corner-out corner material concerning an embodiment. FIG. 2 is a side view and a cross-sectional view of the protruding corner material of FIG. It is a block diagram of the protrusion corner structure which concerns on embodiment.
