BACKGROUND OF THE INVENTION
The present invention relates to a water draining member used between an upper frame of an opening such as a window and an outer wall panel mounted thereon, or between a balcony and a building foundation and an outer wall panel rising from these.
[0002]
[Prior art]
Recently, exterior panels such as ceramic tiles and ceramic materials with excellent fire resistance, water resistance, scratch resistance, chemical resistance, weather resistance, and design are constructed by dry construction via siding materials. There is a lot to do. At the same time, a technology has been developed and put into practical use in which a space is provided between the outer wall panel and the building frame to provide air permeability so as to prevent internal dew condensation and further increase heat retention. However, such an outer wall panel is provided by draining a ceiling of an opening such as a window or the base of a building frame and standing on the drain. Therefore, if rainwater or the like enters the space between the outer wall panel and the building frame from the connecting part of the outer wall panels, there is a problem of water leakage to the indoor side, and the intruding water is discharged to the outside of the outer wall panel. There is a need to.
[0003]
FIGS. 6A to 6C each show a conventional technique for discharging the intrusion water to the outside. As shown in the figure, a predetermined gap 2 is provided on the upper surface of the ceiling portion of the window frame 1 and an outer wall panel 3 is attached. A space 5 for ventilation and heat insulation is formed between the side frame edge 4 and the like of the building frame. Is formed. The outer wall panel 3 is constructed by connecting a large number of exterior materials 3a such as tiles via siding materials attached to the horizontal trunk edge 4 and the vertical trunk edge. In addition, the gap 2 is usually filled with a sealing material 6 such as a modified silicon-based material to improve the appearance and prevent rainwater and dust from entering the space 5 from the gap 2 portion. The sealing material 6 is usually filled after a back-up material 7 such as foamed polyethylene is interposed in the back to reduce the amount of use. In the figure, reference numeral 8 denotes a waterproof sheet, and reference numeral 8a denotes a waterproof tape.
[0004]
By the way, in the case shown in FIG. 6 (A) of the prior art for draining water that has entered the space 5 between the outer wall panel 3 and the building frame side, in the location where the drain hole is to be formed, A back-up material 9 different from the back-up back-up material 7 is disposed, and the remaining portion is filled with the sealing material 6, and then the back-up material 9 is extracted, and the space formed thereafter is used as a drain hole. Yes. Accordingly, the water that has entered the space 5 is discharged to the outside through the drainage hole from an appropriate gap between the backup material 7 and the outer wall panel 3 or the window frame 1.
[0005]
In the prior art shown in FIG. 6B, the sealing material 6 is filled only in the gap 2 at a portion of about 50 mm from both sides of the window frame 1, and the remaining most gap 2 Is left as it is to make a large drainage opening 10, through which water that has entered the space 5 is discharged to the outside.
[0006]
Furthermore, in the prior art shown in FIG. 6C, a backup material 7 is disposed at the back of the gap 2 and the sealing material 6 is filled on the surface side, and a predetermined curing period is set. After the sealing material 6 is cured, a drain hole 11 is drilled with a drilling tool such as a drill so that water that has entered the space 5 is discharged to the outside.
[0007]
[Problems to be solved by the invention]
However, in the prior art shown in FIG. 6A, the back-up material 7 is disposed at the set point of the drainage hole, and it is difficult to press the sealing material 6 when the sealing material 6 is filled. There was also the disadvantage of getting worse.
[0008]
In the prior art shown in FIG. 6B, for example, in a window having a normal glass door with a width of 1800 mm, 1700 mm is provided in the remaining central portion excluding 50 mm on each side. The wide opening 10 of the frontage will be exposed, which is sufficient as a function of draining water that has entered the space 5 on the back side of the outer wall panel 3. However, the wide opening 10 is not preferable because rainwater may enter from the outside. In addition, since the appearance is poor, most of them are not put into practical use.
[0009]
Furthermore, in the prior art shown in FIG. 6C, the drainage hole 11 opened in the sealing material 6 is formed by a drilling jig such as a drill, so that a predetermined dimension is provided from the bottom surface of the gap 2. In some cases, the water is accumulated on the upper surface of the window frame 1. Moreover, since it was a drill hole, the appearance was also bad.
[0010]
[Means for Solving the Problems]
The present invention is obtained by improving and removing the above in view of the above-mentioned problems, and is intended to provide a water draining member used for the drainage structure of the lower end of the outer wall panel which is excellent in workability and has a good appearance.
[0011]
In order to solve the above-mentioned problem, the drainage member employed by the present invention according to claim 1 is disposed in a gap between the lower end surface of the outer wall panel and the drainer located below the outer wall panel, and the rear surface side of the outer wall panel and the outer wall A draining member for communicating with the outside which is the surface side of the panel, comprising a molded body in which an inflow hole and a drain hole are formed, and the drain hole is formed on the front side of the molded body, and the inflow The hole is formed from an inflow port penetrating the left and right side surfaces of the molded body, and the inside of the penetrating hole is filled with a filler for preventing blowing of wind and rain. Two inflow holes may be formed on the back side of the molded body.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The configuration of the present invention will be described below based on the embodiment of the invention shown in the drawings. In addition, the same code | symbol as the conventional case is the same member. 1 to 3 relate to a first embodiment of the present invention, and FIG. 1 is a longitudinal sectional view showing a mounting structure of an outer wall panel 3 on the upper surface side of a window frame 1 and a drainage structure at the lower end thereof. FIG. 2 is a drawing showing the molded body 12 for drainage, and FIG. 3 is a drawing for explaining the construction procedure of the molded body 12.
[0013]
In the first embodiment shown in FIG. 1, in the gap 2 formed between the upper surface side of the window frame 1 and the lower end surface of the outer wall panel 3, the location where the drainage hole is to be formed is shown in FIG. 2. A molded body 12 as a water draining member is shown. The remaining gap 2 is filled with the sealing material 6 after the back-up material 7 is disposed in the back as in the conventional case.
[0014]
The molded body 12 is as shown in FIG. 2A to FIG. 2E, and the size thereof is extremely small, for example, a lateral width of 30 mm, a maximum height of 8 mm, and a depth of 12 mm. The overall shape is a two-step staircase shape, and the inside is a cavity 13. Furthermore, three drain holes 14 are formed to open on the front side of the first stage, and two inflow holes 15 are formed to open on the upper side of the second stage. Further, the entire side surfaces of the second stage portion are openings 16. Moreover, two inflow holes 17 are formed on the back side, and the inside of the cavity 13 is filled with a filler 18 such as sponge.
[0015]
Next, the construction procedure of the molded body 12 configured as described above will be described with reference to FIGS. First, as shown in FIG. 3A, a double-sided adhesive tape 20 is affixed to the bottom surface side of the molded body 12, and a masking sheet 21 is affixed to the front surface side to cover the inflow hole 17. The masking sheet 21 has an extra length so that it can be easily peeled and removed after the sealing material 6 is filled. The double-sided pressure-sensitive adhesive tape 20 and the masking sheet 21 are used by peeling and releasing the release paper, and are widely used.
[0016]
Next, as shown in FIG. 3B, the molded body 12 is disposed at a predetermined position in the gap 2 between the upper surface side of the window frame 1 and the lower end surface of the outer wall panel 3, and the double-sided adhesive tape 20. The release paper is peeled off and fixed to the window frame 1. Then, as shown in FIGS. 2B and 2C, masking tapes 22 and 23 are attached to the upper surface side of the window frame 1 and the lower front surface side of the outer wall panel 3, and the gap 2 is The sealing material 6 is filled. In this case, the filling of the sealing material 6 can be performed roughly, and the pressing after the filling can be performed without interfering with other members, so that the workability is extremely good. Furthermore, unlike the prior art, there is no need to form a drainage structure after the sealing material 6 is dried and solidified, and it is possible to form the drainage structure and fill the sealing material 6 almost simultaneously.
[0017]
Further, due to the presence of the masking sheet 21, the sealing material 6 is not filled into the cavity 13 through the drain hole 14 of the molded body 12, and the drain hole 14 is not blocked. Further, the outer wall panel 3 and the window frame 1 are not stained with the sealing material 6 by the masking tapes 22 and 23. Furthermore, since the bottom surface of the molded body 12 is fixed to the window frame 1 with the double-sided adhesive tape 20, the molded body 12 does not move when the sealing material 6 is filled, and the sealing operation is easy. Finally, if the masking sheet 21 and the masking tapes 22 and 23 are peeled off and removed, the construction of the molded body 12 is completed.
[0018]
Thus, in the molded body 12 having the above-described configuration disposed in the gap 2 between the upper surface side of the window frame 1 and the lower end surface of the outer wall panel 3, the space 5 is formed from the connecting portion of the outer wall panels 3. If rainwater or the like enters the inside, it can be discharged to the outside through the drain hole 14. That is, rainwater or the like that has entered the space 5 flows down to the bottom side of the space 5, and enters the inside from the inflow holes 15 formed on the upper surface side of the molded body 12, the openings 16 on both side surfaces, the inflow holes 17 on the back surface side, and the like. Into the cavity 13. And it naturally flows out to the outside through the drain hole 14 formed in the front side of the molded body 12 and discharged. This is because the upper surface of the window frame 1 constitutes a drainer having an inclined surface with a downward slope toward the outside.
[0019]
The molded body 12 is emphasized on the front side exposed to the outside by the three drain holes 14 and has a unified design as a whole, and the appearance is good. On the other hand, the wind and rain which is going to blow from the outside into the cavity 13 inside the molded body 12 through the drain hole 14 is prevented from entering by the filler 18 such as sponge filled in the cavity 13, and the storm such as typhoon Even at the time of a large amount of water does not enter. Further, after the sealing material 6 is filled, the stepped portion functions to prevent the molded body 12 from popping out, and the molded body 12 is fixed rigidly.
[0020]
4 and FIG. 5 relate to the second and third embodiments of the present invention, and these embodiments are different from the first embodiment shown in FIG. 1 in the structure of the outer wall panel 3. Shows the case of applying to different ones. In the case of the second embodiment shown in FIG. 4, the tile 3a is locked and attached to the base siding material 19, and in the case of the third embodiment shown in FIG. The tile 3a is adhered to the siding material 20. Other configurations and operational effects are the same as those of the above-described embodiments.
[0021]
By the way, this invention is not limited to embodiment mentioned above, For example, what is necessary is just to change suitably the shape of the molded object 12, the structure of the drain hole 14, etc. according to the location where the clearance gap 2 is formed. . Further, the molded body 12 may be formed over the entire width of the gap 2. In this case, the backup material 7 and the sealing material 6 can be omitted. Furthermore, the gap 2 formed between the lower end surface of the outer wall panel 3 and the upper surface of the window frame 1 is formed between the upper surface of various drainers such as a balcony and a building foundation and the lower end surface of the outer wall panel 3. It may be done.
[0022]
