Description

  The present invention relates to an eaves ceiling cutting structure for a balcony, and more particularly, to a structure of an eaves ceiling cutting edge that makes up the eave ceiling of a balcony.

  2. Description of the Related Art Conventionally, there has been known a structure in which a wall parting material having a substantially L-shaped cross section as disclosed in Patent Document 1 is generally provided at a corner portion between an eaves ceiling of a building balcony and an outer wall of the building. Further, a structure in which an eaves-side parting material having a substantially L-shaped cross section is provided at a corner portion between the lower end edge of the curtain curtain plate and the end portion of the eaves ceiling facing the balcony curtain plate is also known.

  In general, the eaves side cutout material is ventilated by providing air vents to send air to the back of the eaves, but insects such as small animals and insects enter the eaves from the vents, or In rainy weather, rainwater may enter the back of the eaves through the vents. Therefore, conventionally, it is common to close the vent hole with a metal mesh.

By the way, a predetermined construction gap is provided between the horizontal piece of the eaves-side parting material having a substantially L-shaped cross section and the lower surface of the eaves ceiling facing the eaves-side parting material. The necessity of providing a gap for construction is that it is difficult to closely contact the horizontal piece of the eaves side parting material without gaps due to warpage of the eaves ceiling, variations in thickness dimensions, construction errors, etc. And it is to be able to construct with good appearance by putting the end portion in the longitudinal direction of the horizontal piece of the wall-side parting material on the upper surface of the horizontal piece of the eave-side parting material and entering the construction gap. However, in the case where such a construction gap is provided, there is a problem that insects easily enter from there.

It is comprised with the eaves-side parting material 3A of the cross-sectional substantially L-shape. The curtain plate 4 is disposed in front of the lower end of the waist wall panel 16 of the balcony 1 shown in FIG. 2, and the back surface of the curtain plate 4 is fixedly supported by the balcony front beam 18 via a receiving member 17.

  In the wall-side parting material 3B having a substantially L-shaped cross section, a vertical piece 19 attached to the building outer wall 21 and a horizontal piece 20 that covers the wall-side end 2b of the eaves ceiling 2 from below are integrally formed.

The eaves-side parting material 3A having a substantially L-shaped cross-section includes a vertical piece 6 that covers the eaves side end 2a of the eaves ceiling 2 from the front and a horizontal piece 5 that covers the eaves side end 2a of the eaves ceiling 2 from below. Is formed. And it is configured doors and both sides by a plurality of eaves side parting member 3A ₁ to 3 A ₃ covering each in this example.

  Here, in the middle of the horizontal piece 5 of the eaves-side parting material 3 </ b> A, an inverted U-shaped portion 7 that opens downward and protrudes upward from the horizontal piece 5 over the substantially entire length of the horizontal piece 5 is formed. Yes. The upper end surface 7a of the inverted U-shaped part 7 is a field edge mounting surface that is attached to the field edge 8 that supports the eaves ceiling 2, and the eaves ceiling 2 rather than the inverted U-shaped part 7 of the eaves-side parting material 3A. The inner horizontal portion 5 a on the side faces the lower surface of the end of the eaves ceiling 2. Furthermore, the inner surface 7b of the inverted U-shaped portion 7 facing the eaves ceiling 2 and the outer surface 7c on the opposite side of the eaves ceiling 2 are respectively formed with vent holes 9 leading to the outdoors. The vent hole 9 is drilled with a drill, for example. Further, a ventilation gap 12 is provided between the inner side surface 7b of the inverted U-shaped portion 7 and the eaves ceiling 2 facing the inverted U-shaped portion 7 so that the vent hole 9 and the eaves back 10 communicate with each other.

  Further, a gap 13 for construction is provided between the inner horizontal portion 5a on the eaves ceiling 2 side of the horizontal piece 5 of the eaves-side parting material 3A and the lower surface of the eaves ceiling 2 facing this. Is formed. The construction gap 13 communicates with the ventilation gap 12 and the end 20b (20a) in the longitudinal direction of the horizontal piece 20 of the wall edge part 3B shown in FIG. 3 is connected to the inner horizontal part 5a of the eaves side part 3A. It has a thickness (for example, about 7 to 8 mm) that can be applied to the upper surface.

  On the other hand, wire nets 14 are disposed on the eaves side parting material 3A that covers the eaves and both sides, respectively. The wire mesh 14 has both an insect repellent function and a draining function that prevent small animals, insects, and the like from entering the back of the eaves 10 without blocking the air flow. The wire mesh 14 of this example is made of, for example, a stainless steel mesh. The reverse U-shaped portion 7 extends from the inner surface of the vertical piece 6 of the eaves-side parting material 3A and has substantially the same length as the entire length of the inverted U-shaped portion 7. And a width dimension capable of reaching the upper surface of the inner horizontal portion 5a through the upper end surface 7a. Here, one end of one wire mesh 14 is adhered to the inner surface of the vertical piece 6 of the eaves-side parting material 3A with an adhesive, and horizontally from the inner surface of the vertical piece 6 to the upper end surface 7a of the inverted U-shaped portion 7. Further, the air gap 12 is partitioned obliquely from the upper end surface 7a of the inverted U-shaped portion 7 to reach the upper surface of the inner horizontal portion 5a, and the other end of the metal mesh 14 is connected to the inner horizontal portion. The upper surface of 5a is adhered with an adhesive. The wire mesh 14 is not limited to adhesion, and may be attached by screw screws or other methods. Furthermore, the eaves-side end 2a of the eaves ceiling 2 abuts in the middle of the slanted wire mesh portion 14a, so that one wire mesh 14 functions to partition the ventilation gap 12 and the construction gap 13. It plays the role of partitioning.

  Next, an example of the construction procedure will be described. First, after fixing the field edge 8 to the lower end side of the balcony 1 and fixing the vertical piece 19 of the wall edge part 3B to the building outer wall 21, the wall side end 2b of the eaves ceiling 2 is set to the horizontal piece 20 of the wall edge part 3B. The eaves ceiling 2 is attached to the field edge 8 in a state of being stretched over the upper surface of the roof. Then, the eaves-side parting material 3A that covers the eaves and both sides is attached along the eaves-side end 2a (three sides other than the wall-side end) of the eaves ceiling 2.

Here, the plurality of eaves-side parting materials 3A covering the eaves and both sides have the same cross-sectional shape, and hereinafter, the one-side eaves-side parting material 3A ₁ shown in FIG. The description will be made as the material 3A ₂ and the eaves side parting material 3A ₃ on the eaves side. A wire mesh 14 is bonded in advance to the upper surface of each eaves-side parting material 3A _{1 to} 3A ₃ (state shown in FIG. 3).

Then, the wall-side end of the eaves-side parting material 3A ₁ disposed on one side of the eaves ceiling 2 is overlapped with the lower surface of the longitudinal end part 20a of the horizontal piece 20 of the wall-side parting material 3B, and state that enter one end 20a of the crosspiece 20 of the wall parting member 3B in construction for the gap 13 (the state in FIG. 2 (b)), the upper end surface 7a of the inverted U-shaped portion 7 of the eaves side parting member 3A ₁ Then, a tapping screw is driven into the edge 8 to fix the eaves-side parting material 3A ₁ to the edge 8. Further, the other side eaves-side parting material 3A ₂ arranged on the other side part of the eaves ceiling 2 was made to enter the construction gap 13 with the other end 20b of the horizontal piece 20 of the wall-side parting material 3B in the same manner. In the state, the eaves-side parting material 3A ₂ is fixed to the field edge 8. Also, at the corner portion where the longitudinal end portion and eaves tip of eaves side parting member 3A ₁ eaves side of eaves side parting member 3A ₃ disposed eaves tip eaves roof 2 is butted, that Since the abutting surface 25 (FIG. 4) has the same cross-sectional shape, for example, an L-shaped joint fitting (not shown) is attached to the locking piece 23 (FIG. 1) provided on the inner surface of each of the two-piece parting materials 3A ₁ , 3A ₃ . ) Is engaged and locked. Similarly, connecting butt surface 24 of the other longitudinal end portion and eaves tip of eaves side parting member 3A ₂ eaves side parting member 3A ₃ (FIG. 4) in L-shaped joint fitting. Then, by implanting tapping screws 26 (FIG. 1) from the upper end surface 7a of the inverted U-shaped portion 7 of the eaves side parting member 3A ₃ to ceiling joists 8, fixing the eaves-side parting member 3A ₃ to ceiling joists 8. The upper edge of each of the eaves-side parting materials 3A _{1 to} 3A ₃ is waterproofed with a caulking material 22 in a state where it is applied to the front surface of the receiving material 17 of the curtain plate 4.

In the state of attaching the respective eaves side parting member _3A 1 to 3 A ₃ as described above, of the wire net 14 attached to the respective eaves side parting member _3A 1 to 3 A _3, eaves oblique wire mesh portions 14a ceiling 2 The construction gap 13 between the eaves ceiling 2 and the inner horizontal part 5a is partitioned by an oblique wire mesh part 14a ₁ below the lower surface of the eaves ceiling 2 by abutting with the tip corners of the lower surface of the eaves (State of FIG. 1).

According to the above configuration, outdoor air, as indicated by arrows a, b in FIG. 1, in each of the eaves side parting member 3A _(3A 1 ~3A _3), the vent holes 9 and construction of the inverted U-shaped portion 7 The air gap 13 is fed into the eaves 10 to ventilate the attic 11. Insects such as small animals and insects that enter through the air vent 9 are stopped by an oblique wire mesh portion 14 a that partitions the air gap 12. The rainwater blown from the ventilation hole 9 during wind and rain flows down to the inner horizontal portion 5a through the oblique wire mesh portion 14a, and is drained from there to the eaves. On the other hand, since the construction gap 13 is partitioned by an oblique wire mesh portion 14a ₁ below the lower surface of the eaves ceiling 2, insects and rainwater entering the construction gap 13 are also stopped by the wire mesh portion 14a ₁ . The rainwater flows down through the wire mesh portion 14a ₁ and is drained further under the eaves. As a result, each of the eaves-side parting materials 3A _{1 to} 3A ₃ has an advantage that a waterproof / insect-proof effect can be obtained in the ventilation gap 12 and the construction gap 13 by the single wire mesh 14. Further, in this example, the horizontal wire mesh portion 14b is disposed across the vertical piece 6 of the eaves-side parting material 3A from the upper end surface 7a of the inverted U-shaped portion 7, so that the outer side surface 7c of the inverted U-shaped portion 7 is provided. Even when the vent hole 9 is provided, there is an advantage that insects and rainwater can be prevented from entering from the vent hole 9.

  In addition, the wire mesh 14 is attached to the eaves-side parting material 3A in advance, and the eaves-side parting material 3A is fixed to the field edge 8 so that the diagonal wire mesh part 14a is pressed against the eaves-side end 2a of the eaves ceiling 2. Thus, since both the ventilation gap 12 and the construction gap 13 are partitioned, there is an advantage that the labor of construction can be greatly reduced.

  Further, the reverse U-shaped portion 7 in which the air holes 9 are formed is formed in a part of the horizontal piece 5 of the eaves-side parting material 3A, thereby reinforcing the eaves-side parting material 3A (retaining property). In addition, the upper end surface 7a of the inverted U-shaped portion 7 is used as a field mounting surface, so that the upper end surface 7a of the inverted U-shaped portion 7 is used as a space for driving the tapping screw 26. In addition, there is an advantage that the head of the tapping screw 26 can be concealed from the eaves.

  By the way, the reverse U-shaped part 7 of the eaves-side parting material 3A corresponding to the roof balcony 1A is formed by drilling the air holes 9 with a drill, but as shown in FIG. The protruding balcony 1B constructed so as to protrude does not necessarily require ventilation unlike the balcony 1A on the roof, so that a molded product that does not drill the vent hole 9 with a drill is taken out as it is and the eave side of the balcony 1B It can be used as a parting material 3A. Therefore, since the eaves sighting edge 3 of the present invention can be shared by both the roof balcony 1A and the take-out balcony 1B, there is an advantage that it is possible to reduce labor and cost for producing two types of eave heaven edges. In FIG. 5, reference numeral 70 denotes a bridge receiving beam, 72 a balcony floor receiving beam, 73 an eaves ceiling base material, 74 a hanging tree, and 75 a hanging tree receiving.

  Moreover, in the said embodiment, although the metal-mesh part 14b from the inner surface of the vertical piece 6 of the eaves-side parting material 3A to the upper end surface 7a of the reverse U-shaped part 7 was stretched horizontally, this metal-mesh part 14b is diagonally arrange | positioned May be. An example is shown in FIG. In this example, rainwater entering from the air holes 9 on the outer surface 7c of the inverted U-shaped portion 7 is also drained down the eaves along the slanted wire mesh portion 14b. It can be prevented from accumulating inside.

  Another embodiment of the present invention is shown in FIG. For example, a tile 31 (or a brick or the like) is pasted on the surface of the waist wall panel 16 (FIG. 5) of the balcony 1 and the surface of the curtain plate 4. In this case, the outer surface of the eaves-side parting material 3A is If the design of the tile-like waist wall panel 16 and the tile-like curtain board 4 is recessed in the eaves-side parting material 3A without being continuous, and the entire residential building is viewed as a whole, a profound and real feeling is obtained. In some cases, it may be cheaper.

Therefore, in this example, as shown in FIG. 7, the tile-like waist wall panel 16 and the outdoor side of the eaves-side parting material 3A (the eaves-side parting material 3A ₁ , 3A ₂ , 3A ₃ ) and A tile parting material 3C continuous with the tiled curtain plate 4 is fitted. The front part 30 of the tile parting material 3 </ b> C is flush with the tiled curtain plate 4. Note that the upper edge 30 a of the front surface portion 30 of the tile parting material 3 </ b> C is fixed to the curtain plate 4 with a tapping screw 32 on the back surface of the tile 31 located at the lower front edge of the curtain plate 4. 7 in FIG. 7 is a locking piece for locking the L-shaped joint fitting that connects the ends of the tile parting material 3C abutted at the corner part, and 34 is a horizontal piece 5 of the eave side parting material 3A. A projecting portion 36 is a hook portion that can be hooked on the projection 35 at the lower end of the inverted U-shaped portion 7 of the eaves-side parting material 3A.

  Thus, by covering the eaves-side parting material 3A with the tile parting material 3C and making the front surface portion 30 of the tile parting material 3C substantially flush with the surface of the tiled curtain plate 4, the tile-like waist wall panel 16 and the tile The curtain plate 4 and the tile parting material 3C have a continuous appearance finish, and a solid feeling, real feeling, and luxury feeling can be obtained as a whole. Also, the hook part 36 at the lower end of the tile parting material 3C is hooked on the protrusion 35 at the lower end of the inverted U-shaped part 7 of the eaves side parting material 3A, and the upper end part of the tile parting material 3C is tapped with the tapping screw 32. 4 only has to be fixed, and the tile parting material 3C can be easily attached.
