Description

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

  As a parting structure for exterior materials, a parting structure in which a draining plate separate from the parting edge is attached below the parting edge and the water that flows down the outer wall is drained by the draining plate is generally known. (For example, refer to Patent Document 1).

  As an example, for example, as shown in FIG. 5, the draining plate 30 is rivet-fixed so as to protrude to the front K below the parting edge 3 ′, and the upper part of the draining plate 30 is parted and the lower end of the parting edge 3 ′ and the exterior material A structure is known in which water drops such as rain water and condensed water flowing down from the window lower frame 1A are drained by a draining plate 30 by being inserted between the two. 50 in the figure is a waterproof sealant.

However, in the conventional draining structure, the draining plate 30 must be separately installed at the site, and the number of parts needs to be increased and rivets must be fixed. . In addition, since the parting edge 3 ′ and the draining board 30 are arranged in the vertical direction, there is a problem that the width of the appearance increases, and when the color pattern of the parting edge 3 ′ and the draining board 30 is different, the appearance is uncomfortable. Color matching is required to give the image, and there is a problem that the labor and cost of construction increase.
Japanese Patent Laid-Open No. 9-60184

  The present invention has been invented in view of the above-described conventional problems, and can provide a draining function at the parting edge, improving the workability on site and improving the upper and lower appearance width of the entire parting cover part. The goal is to provide a parting structure for exterior materials that can be made small and fit well, and color matching between the parting edge and the draining part is not required, and can greatly reduce the labor and cost of construction. It is an object of the present invention to provide a parting structure for an exterior material that can satisfactorily finish the process.

  In order to solve the above-mentioned problems, the present invention provides a parting structure for an exterior material in which the parting edge 3 is attached to the upper end portion 2a of the exterior material 2 under the window facing the lower window frame 1A. The parting base part 5 is divided into a base part 5 and a parting cover part 6, and the parting base part 5 protrudes forward K from the rear side vertical piece 5 a disposed behind the exterior material 2 and the upper end part 2 a of the rear side vertical piece 5 a. The front projecting horizontal piece 5b and the engaging portion 5c provided at the front end of the front projecting horizontal piece 5b and spaced from the upper end 2a of the exterior material 2 are integrally configured, and the parting cover 6 Are provided at the front vertical piece 6a disposed on the front surface 2b of the exterior material 2, the rear protruding horizontal piece 6b protruding backward H from the upper end 2a of the front vertical piece 6a, and the tip of the rear protruding horizontal piece 6b. To be engaged and connected to the engaging portion 5c of the parting base portion 5 The draining portion 7 is configured integrally with the portion 6c, and projects from the lower end side of the front vertical piece 6a toward the front K of the exterior material 2 over its entire width, and the projecting tip portion hangs downward. Is characterized by being integrally projected.

  By having such a configuration, the parting edge 3 itself can have a draining function by integrally projecting the draining part 7 projecting forward K on the front vertical piece 6a of the parting cover part 6, As a result, compared to the conventional case where the parting edge 3 and a separate draining plate are used, construction on site can be omitted, and the front vertical piece 6a of the parting cover 6 and the draining part 7 can be integrated. The upper and lower external appearance width of the entire parting cover part 6 can be reduced, and color matching between the parting edge 3 and the draining part 7 is also unnecessary.

  In addition, it is preferable that the rear vertical piece 5a of the parting base portion 5 is provided with a protruding portion 5d that protrudes above the front protruding horizontal piece 5b and whose tip can contact the lower surface of the window lower frame 1A. In this case, the sealing gap 40 can be secured between the upper surface of the parting edge 3 and the lower surface of the window lower frame 1A by the protrusion 5d, and the mounting height of the parting edge 3 is calculated in the field in order to secure the sealing gap 40. There is no need.

  In addition, the front end portion 8a is connected to the draining portion 7 and the rear end portion 8b is in contact with or spaced from the front surface 2b of the exterior material 2 and is inclined upward as the distance from the draining portion 7 increases. The lower cover portion 8 is preferably provided integrally. In this case, the closing edge 3 can be satisfactorily closed by the lower cover portion 8 while the draining portion 7 is overhanging.

  In the invention of claim 1, it is unnecessary to separately attach a conventional draining plate by projecting the draining unit integrally so as to project forward from the lower end side of the front vertical piece of the parting cover part, The rivet fixing of the draining plate can be omitted and the number of parts can be reduced, so that the workability on site can be improved. Also, by giving the draining function to the parting edge itself, the upper and lower appearance width of the parting cover part is reduced. Thus, it is possible to obtain a good fit, and further, it is not necessary to match the color of the parting edge and the draining part, and it is easy to align the sash window frame and the approximate color.

  In the invention according to claim 2, since the sealing gap can be secured between the upper surface of the parting edge and the lower surface of the window lower frame by the protrusion protruding from the rear vertical piece of the parting base part, This eliminates the need to perform calculations on-site, and can further reduce construction work on-site.

  According to the third aspect of the present invention, it is possible to satisfactorily finish the parting edge in which the draining portion is projected by the lower cover portion.

  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 upper end portion 2a of the exterior material 2 under the window facing the window lower 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 lower window frame 1 </ b> A, an unillustrated window upper frame, and a pair of left and right window side frames are integrally assembled in a rectangular shape in front view.

  The exterior material 2 under the window is made of, for example, metal siding, and the parting edge 3 into which the upper end portion 2a is fitted is made of, for example, a thin steel plate. Further, a backup material 10 and a waterproof sealing material 11 are filled in a gap between the window lower frame 1 </ b> A and the upper surface portion of the parting edge 3.

  Here, in the present invention, the parting edge 3 is divided into two parts in the front-rear direction: a parting base part 5 disposed behind the exterior member 2 and a parting cover part 6 disposed on the front surface of the exterior member 2.

  The parting base 5 includes a rear vertical piece 5a disposed behind the exterior material 2, a front protruding horizontal piece 5b protruding forward K from the upper end 2a of the rear vertical piece 5a, and a front protruding horizontal piece 5b. The engaging portion 5c provided at the front end portion of the exterior member 2 and spaced from the upper end portion 2a of the exterior member 2 is integrally formed.

  The parting cover portion 6 includes a front vertical piece 6a disposed on the front surface 2b of the exterior material 2, a rear protruding horizontal piece 6b protruding backward H from the upper end 2a of the front vertical piece 6a, and a rear protruding horizontal piece 6b. An engaged portion 6c provided at the distal end portion and hooked and connected to the engaging portion 5c of the parting base portion 5 is integrally formed.

  In this example, the engaging part 5c of the parting base part 5 is configured by folding the front end part of the front protruding horizontal piece 5b back and downward in a m-shape. On the other hand, as shown in FIG. 2B, the engaged portion 6c of the parting cover portion 6 can be elastically deformed in the vertical direction when the tip end portion of the rearward projecting horizontal piece 6b is folded back in a V shape toward the rear H. A V-shaped folded portion 6c1 and a hook portion 6c2 obtained by further folding back the lower end of the V-shaped folded portion 6c1 are elastically deformable in the vertical direction. It is structured to be hooked and detachable.

  Moreover, the draining part 7 protrudes integrally from the lower end side of the front side vertical piece 6a. As shown in FIG. 1, the draining portion 7 hangs downward from a protruding portion 7 a that protrudes toward the front K of the exterior material 2 over the entire width of the front vertical piece 6 a, and a tip portion of the protruding portion 7 a. A drooping portion 7b and a draining portion 7c sharpened at an acute angle at the lower end of the drooping portion 7b are integrally formed.

Furthermore, in this example, the lower end portion of the parting cover portion 6 has a lower cover portion 8 in which the front end portion 8a is continuous with the hanging portion 7b of the draining portion 7 and the rear end portion 8b is in contact with the front surface 2b of the exterior material 2. It is provided integrally. The lower cover portion 8 in this example is inclined upward as it is away from the draining portion 7 so as not to impair the draining function of the draining portion 7. The lower cover portion 8 in this example has a long shape in which the rear end portion 8b is brought into contact with the front surface 2b of the exterior material 2 and has a bent end. However, the shape is not limited to this shape. 2 may be a short shape arranged with a gap from the front surface 2b and the tip may be a free end shape,
Next, the construction procedure of the parting edge 3 will be described. First, the rear vertical piece 5a of the parting base portion 5 is fixed to the horizontal trunk edge 4 which is the exterior base material with a nail 14a at a position above the lower end ear portion 16, and then the upper end portion of the exterior material 2 2a is fixed to the horizontal trunk edge 4 with the nail 14b through the rear vertical piece 5a. Thereafter, the parting cover part 6 is held by hand, and the rearward projecting lateral piece 6b of the engaged part 6c is positioned above the forward projecting lateral piece 5b of the engaging part 5c of the parting base part 5 as shown in FIG. And when the hook portion 6c2 of the engaged portion 6c is positioned below the engaging portion 5c, the V-shaped folded portion 6c1 of the engaged portion 6c is inserted obliquely from the lower front toward the engaging portion 5c. The V-shaped folded portion 6c1 expands and the hook portion 6c2 moves while sliding on the lower surface of the engagement portion 5c, and is hooked and connected by elastic locking from below the engagement portion 5c. The hooking direction of the hook portion 6c2 is a direction (vertical direction) perpendicular to the insertion / removal direction (front-rear direction) of the parting cover portion 6, so that the hook portion 6c2 is reliably prevented from coming off from the engaging portion 5c as shown in FIG. It becomes a state. Thereafter, the back-up material 10 and the waterproof sealing material 11 are filled in the sealing gap 40 between the upper surface portion of the parting edge 3 and the window lower frame 1A to complete the installation.

  Accordingly, since the water such as rain water and dew condensation water from the window lower frame 1A can be drained by the draining portion 7 of the parting cover portion 6 and can be washed off to the ground, the rain water, water droplets, etc. can be removed from the exterior material 2 under the window. Thus, the exterior material 2 can be prevented from being soiled. That is, since the parting edge 3 has a structure having a draining function in addition to the original makeup function, the effect of preventing contamination of the exterior material 2 can be obtained without using a conventional draining plate.

  In addition, since a conventional draining plate can be separately attached, and rivet fixing of the draining plate can be omitted and the number of parts can be reduced, construction on the site is extremely easy.

  Furthermore, the parting cover part is formed by projecting the draining part 7 integrally from the front vertical piece 6a of the parting cover part 6 as compared with the case where a conventional parting edge 3 and a separate draining plate are attached. 6 It becomes easy to reduce the upper and lower external appearance widths, and the fit is good. Moreover, since the parting edge 3 and the draining part 7 can be unified in the same color pattern, the conventional color matching is not necessary, and it is also easy to align with the sash window frame 1 and the approximate color.

  Further, in this example, the parting edge 3 is finished by providing the lower cover part 8 that covers the gap between the draining part 7 and the exterior material 2 from below in the parting cover part 6 while the draining part 7 is overhanging. There exists an advantage which can be made favorable by the lower cover part 8. FIG.

  Furthermore, in this example, the parting edge 3 is divided into the parting cover part 6 and the parting base part 5 in the front and rear direction, and the upper end part 2a of the parting cover part 6 is hooked and connected to the upper end part 2a of the base part 5. 3 can be assembled with one touch. Moreover, since the engaging part 5c of the parting base 5 and the engaged part 6c of the parting cover part 6 are a simple hook connection method, the part can be removed with one touch. That is, when removing the parting cover part 6, the waterproof sealing material 11 and the backup material 10 are removed, and then the parting cover part 6 is held by hand and pulled diagonally forward and upward, the V-shaped folding of the engaged part 6 c is performed. Since the part 6c1 expands and the hooking part 6c2 is pulled out below the engaging part 5c, it can be removed with one touch, so that the parting edge 3 can be easily maintained and replaced.

  FIG. 3 shows another embodiment of the present invention. The rear vertical piece 5a of the parting base 5 protrudes above the front protruding horizontal piece 5b so that the tip can contact the lower surface of the window lower frame 1A. An example in the case where a simple protrusion 5d is provided is shown. Other configurations are the same as those of the embodiment of FIG. 1, and corresponding portions are denoted by the same reference numerals. Incidentally, when the rear vertical piece 5a of the parting edge 3 is attached to the exterior base material 4 as shown in FIG. 2, a predetermined sealing gap 40 is secured between the upper surface of the parting edge 3 and the lower surface of the window lower frame 1A. As described above, it is necessary to perform the mounting operation while calculating the mounting height of the rear vertical piece 5a at the site. On the other hand, in this example, the attachment height of the rear vertical piece 5a is determined simply by bringing the tip of the projection 5d into contact with the lower surface of the window lower frame 1A, and the sealing gap 40 can be easily secured without being calculated. Thus, the labor of attaching the parting edge 3 at the site can be reduced. Further, since the rib-shaped protrusion 5d of this example also functions as the backup material 10 (FIG. 1) of the waterproof sealing material 11, there is an advantage that the backup material 10 (FIG. 1) can be omitted. The shape of the protruding portion 5d is not limited to the shape protruding over the entire width of the upper end portion of the rear vertical piece 5a, and, for example, protrudes from a plurality of positions with an interval in the width direction of the upper end portion of the rear vertical piece 5a. The shape may be sufficient, and the shape may be any shape as long as the sealing gap 40 can be secured by hitting the lower surface of the window lower frame 1A.

  In the above embodiment, the case where the sealing gap 40 is filled with the paste-like waterproof sealing material 11 (FIG. 1) is illustrated, but as another example, as shown in FIG. 4, the upper surface of the rear protruding horizontal piece of the parting cover portion It is also possible to stick a solid watertight packing 11a in advance. As a result, it is possible to save the trouble of the on-site sealing work. Further, the watertight packing 11a may be a solid one that does not require the backup material 10 (FIG. 1).
