Description

  The present invention relates to a parting structure for an exterior material in which a parting edge is attached to the lower end portion of the exterior material on the window facing the window upper frame, and more particularly to a structure in which the parting edge has a draining function.

  As a conventional draining structure of the outer wall, there is generally known a structure in which a drain hole is provided in the bottom part of the parting edge, and water that has entered the parting edge through the outer wall is drained to the outside through the drain hole. (For example, refer to Patent Document 1).

  As an example, for example, as shown in FIG. 6, a parting edge 3 ′ having a substantially U-shaped cross section is attached to the lower end part 2 a of the exterior material 2 disposed on the upper surface of the window upper frame 1 </ b> A. There is known a draining structure in which a drain hole 10 is formed and the water that has entered the parting edge 3 ′ through the exterior material 2 is drained from the drain hole 10.

However, in the conventional draining structure, when the lower end portion 2a of the exterior material 2 hits the parting bottom surface portion 7, the drain hole 10 is blocked, the drainage performance is deteriorated, and the draining function of the exterior material 2 is impaired. . Therefore, it is necessary to perform construction with a gap so that a predetermined distance d is provided between the lower end portion 2a of the exterior material 2 and the parting bottom surface portion 7, and it takes time and labor for construction on site. In addition, since the drain hole 10 is drilled downward in the parting bottom surface portion 7, it is necessary to consider the contact with the sealing material 20 when drilling at the site, and therefore the position of the drain hole 10 is extremely narrow. There is a problem that it is limited to the range, and it becomes difficult to improve drainage, and there is also a problem that a backup material 30 is required when the waterproof sealing material 20 is in a paste form.

In addition , since it is not necessary to consider the connection between the drain hole and the water tight packing, the opening area of the drain hole can be greatly increased, drainage can be further improved, and solid water tight packing is used. This can simplify the on-site sealing work.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 shows a state in which the parting edge 3 of this embodiment is attached to the lower end 2a of the exterior material 2 on the window facing the window upper frame 1A.

  In FIG. 1, a window frame base material 13 is fixed along a peripheral edge portion of a window mounting opening provided in the building frame, and the sash window frame 1 is attached to the window frame base material 13. . In the sash window frame 1, a window upper frame 1 </ b> A, a window lower frame (not shown), and a pair of left and right window side frames are integrally assembled in a square shape when viewed from the front. In FIG. 1, 14 is a moisture-proof waterproof sheet and 15 is a waterproof tape.

  The exterior material 2 on the window is made of, for example, metal siding, and the parting edge 3 into which the lower end 2a is fitted is made of, for example, a thin steel plate.

  The parting edge 3 is formed by integrally forming a parting base part 5 attached to the exterior base material 4, a parting cover part 6 disposed on the front surface of the exterior material 2, and a parting bottom part 7 in a substantially U-shaped cross section. Yes. Ear parts 16 and 17 are formed by bending the upper end edges of the parting cover part 6 and the parting base part 5, respectively.

  Here, in the present invention, the mounting step portion 8 bent in an L-shaped section toward the inner side G is formed at a position above the lower corner portion 6a (FIG. 2B) of the parting cover portion 6. Has been. The mounting step 8 serves to secure a space 9 between the lower end 2 a of the exterior material 2 and the parting bottom surface 7 by placing a part 2 b of the lower end 2 a of the exterior material 2. do. In this example, the placing step 8 is formed over the entire width of the parting cover 6. Further, as an example of the size of the mounting step portion 8, for example, the front-rear width A of the parting edge 3 shown in FIG. 2A is about 20 mm, the height B of the parting base portion 5 is about 55 mm, and the height of the parting cover portion 6. When the length C is about 28 mm, the height D of the mounting step 8 is about 10 mm, for example, and the inward bending dimension E of the mounting step 8 is about 5 mm, for example. Of course, these numerical values are examples, and the design can be changed as appropriate.

  Further, the lower end portion of the parting cover part 6 enters the inner side G by the placing step part 8 described above, and water that communicates with the space part 9 is formed in the lower corner portion 6a of the parting cover part 6 that has entered the inner side G. The punch hole 10 opens toward the front K (outdoor side). In the example shown in FIGS. 2 and 3, the drain hole 10 of the present example is opened across the corner portion 12 extending from the lower corner portion 6 a of the parting cover portion 6 to the front corner portion 7 a of the parting bottom surface portion 7. The parting cover portion 6 is wide open in the shape of an elongated hole along the width direction F, and the opening area is increased.

  A watertight packing 11 is loaded in a gap 18 between the lower surface 7b of the parting bottom surface portion 7 and the window upper frame 1A. The watertight packing 11 is loaded at a position where the drain hole 10 closer to the rear H (indoor side) than the opening position of the drain hole 10 is not blocked. In addition, as the watertight packing 11, what is necessary is just a solid thing which does not require a backup material, and the material in particular is not ask | required.

  Thus, according to the above configuration, after the parting base portion 5 is fixed to the lateral trunk edge 4a which is the exterior base material 4 by the nail 19, the lower end part 2a of the exterior material 2 is parted from the upper part. When inserted into the inside, a part 2b of the lower end 2a of the exterior material 2 is placed on the mounting step 8 bent to the parting cover portion 6 so that the lower end 2a of the exterior material 2 is parted. A space portion 9 that leads to the drainage hole 10 is secured below the exterior material 2 without hitting the bottom surface portion 7, and water such as rain water and condensed water that falls along the exterior material 2 drains through the space portion 9. The water is smoothly drained from the hole 10. Therefore, the trouble of providing the space portion 9 on the site is saved, and construction on the site can be greatly reduced.

  Further, in this example, since the mounting step 8 is bent in an L shape inwardly, the water falling along the surface of the parting cover 6 is drained at the bent portion 8a of the mounting step 8. Thus, it is prevented from flowing down to the drain hole 10 in the lower corner portion 6a of the parting cover portion 6. Furthermore, since the front end portion of the watertight packing 11 loaded on the lower surface 7 b of the parting bottom surface portion 7 is disposed closer to the rear H than the opening position of the water draining hole 10, the watertight hole 11 closes the water draining hole 10. Thus, the drainage discharged from the drain hole 10 is prevented from entering the building through the gap 18 between the parting bottom portion 7 and the window upper frame 1A.

  Moreover, since the solid watertight packing 11 can be attached in advance to the lower surface 7b of the parting bottom surface portion 7, and since a backup material necessary for applying a pasty sealing material as in the past can be omitted, It is possible to further reduce the construction and cost on site.

  Further, since the drain hole 10 is parted and formed in the lower corner portion 6a of the cover portion 6, it is not necessary to consider the connection between the drain hole 10 and the watertight packing 11. In addition, the drain hole 10 of this example is open across the corner portion 12 from the lower corner portion 6a of the parting cover portion 6 to the front corner portion 7a of the parting bottom surface portion 7, and has a long hole shape that is long in the lateral direction. Therefore, the opening area of the drainage hole 10 can be greatly expanded while not being blocked by the watertight packing 11. Further, by forming the drain hole 10 in advance in the factory, it is possible to omit the drilling at the site and to form the drain hole 10 in advance with a good appearance, and there is an advantage that the appearance of the parting edge 3 is improved.

  FIG. 4A shows another embodiment of the present invention, and shows an example of a case where a down slope is provided on the parting bottom surface portion 7 so as to form a down slope toward the front side. The intruding water is surely guided to the drain hole 10 side through the bottom surface portion 7 and the drainage performance can be further improved.

  FIG. 4B shows still another embodiment, in which the watertight packing 11 is parted and may be provided on the upper surface of the window upper frame 1A facing the lower surface 7b of the bottom surface portion 7. In this case, Instead of the watertight packing 11, a paste-like waterproof sealing material can be used.

  Note that the placement step 8 is not limited to being formed on the parting cover part 6, and for example, as shown in FIG. 5, the parting base part 5 is bent toward the inner side G to place the placement step 8. It is also possible to use part 8.
