DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainer for receiving an outer wall panel on an upper wall of a window sash frame.

[0002]

2. Description of the Related Art A draining material for a vertical-type outer wall panel includes a draining material for a base and a draining material for connection. For example, the latter is known in Japanese Utility Model Application Laid-Open No. 63-116606. Here, a connection groove that opens upward along the longitudinal direction of the drainer is formed, and the lower end of the outer wall panel is fitted into this connection groove. A drain hole is formed at the lower end of the front wall of the connection groove. Japanese Patent Publication No. Hei 6-23515 discloses a drainer for a base provided with a connection groove similar to the drainer described above, and the upper part of the front wall forming the connection groove is bent stepwise. A step is formed,
A concave portion formed by the step and the outer wall of the outer wall panel is filled with a caulking material.

[0003]

On the window sash frame,
The outer wall panel is assembled based on the upper surface wall, and a drainer is used there. This type of draining material includes a mounting wall fixed to a wall base material, a receiving wall inclined downward from the lower end of the mounting wall toward the outside (front), a skirt wall bent downward from a front end of the receiving wall, and the like. It has a crank-shaped cross section. In the case of a conventional window frame such as a wooden sash or a metal sash that follows the structure, the above-mentioned draining material can be applied without any trouble. However, in a window sash frame in which the top wall protrudes outward from the outer wall panel in an eaves shape, the skirt wall is in most cases obstructive.
Cannot use window drainer. In many cases, the lower end of the outer wall panel is supported by the upper wall via a spacer or a backing material for caulking, and the construction is adopted in which the space between the lower edge front edge of the outer wall panel and the upper wall is sealed with the caulking material. .
In other words, the waterproofing is performed only with the caulking material, and the waterproof function during long-term use remains uneasy.

[0004] Although it is easy to form a drainer suitable for a sash shape, the inclination angle of the upper surface wall and the size of the protrusion in the outdoor direction are not constant depending on the difference between sash makers and varieties. However, it is not cost-effective to prepare a drainer for each window sash frame.

An object of the present invention is to provide a drainer which can be applied to all window sash frames whose upper wall protrudes outside from the front surface of the outer wall panel and is excellent in versatility. An object of the present invention is to provide a drainer that can continue to exhibit a sufficient waterproof function for a long time. An object of the present invention is to provide a drainer that can be firmly attached in a stable state even when the inclination angle of the upper wall is different from the upper wall of the window sash frame or when the inclination angle varies. To offer.

SUMMARY OF THE INVENTION The present invention is directed to a drainer for receiving an outer wall panel 3 mounted above an upper wall 5 of a window sash frame 1 as shown in FIG. The upper surface wall 5 extends forward and outward from the outer wall panel 3, and in many cases, is inclined forward and downward at a predetermined angle. The draining material 4 has a mounting wall 7 fixed to the wall base material 2, a horizontal receiving wall 8 extending forward from a lower end of the mounting wall 7, and a front wall 10 covering a lower front surface of the outer wall panel 3. The lower end of the front wall 10 and the front end of the receiving wall 8 are connected by an inclined wall 11. The lower end of the inclined wall 11 is provided with drain holes 14 at appropriate intervals in the left-right direction.

The present invention also provides a mounting wall 7 similar to that described above.
And a relatively large gap is provided between the outer wall panel 3 and the front wall 10 between the outer wall panel 3 and the front wall 10 in the draining member formed of a horizontally long strip having the receiving wall 8 and the front wall 10, A step wall 20 for receiving the caulking material 19 is provided on the upper inner surface of the front wall 10 so as to protrude toward the mounting wall 7.
Drain holes 14 are provided at the lower end of the inclined wall 11 at appropriate intervals in the left-right direction.

The present invention also provides a mounting wall 7 similar to that described above.
And a relatively large gap is provided between the outer wall panel 3 and the front wall 10 between the outer wall panel 3 and the front wall 10 in the draining member formed of a horizontally long strip having the receiving wall 8 and the front wall 10, A step wall 20 for receiving the caulking material 19 is provided on the upper inner surface of the front wall 10 so as to protrude toward the mounting wall 7.
A groove wall 21 is recessed downward between the step wall 20 and the receiving wall 8, and a drain hole 14 is provided at a lower end portion of the groove wall 21 at an appropriate interval in the left-right direction.

More specifically, the outer wall panel 3 is composed of a front panel 3a made of a steel plate as a base material and a backing material 3b lined on the indoor side of the front panel 3a.
A protection wall 17 is provided at the lower end of the front panel 3 by folding the front panel 3a toward the lower surface of the backing material 3b. Then, the lower end of the outer wall panel 3 is received by the receiving wall 8 via the protective wall 17.

[0010]

The drainer 4 fastens the mounting wall 7 to the wall base material 2 with the mounting wall 7 circumscribing the upright wall 6 of the window sash frame 1 and the lower end of the front wall 10 being received by the upper wall 5. In this mounting state, the lower end of the front wall 10 is always kept at the lower end of the upper wall 5 irrespective of whether the upper wall 5 projects outside from the front of the outer wall panel 3 or the inclination angle of the upper wall 5 varies.

The gap between the upper end of the front wall 10 and the outer wall panel 3 is filled with a caulking material 19 to prevent rainwater from entering the inside. When rainwater enters the inside of the draining material 4 due to deterioration of the caulking material 19 due to long-term use, the rainwater goes out of the drain hole 14 and does not enter the inside of the wall. Since the lower end of the front wall 10 is received by the upper wall 5, it is possible to prevent rainwater from entering the inside from the outside. The reason why the drain hole 14 is not provided at the lower end of the front wall 10 is to eliminate the blowing of rainwater. The lower end of the outer wall panel 3 fits into the connecting groove 12 formed by the three members of the mounting wall 7, the receiving wall 8, and the front wall 10, so that the lower end of the outer wall panel 3 is drained with the drainage material 4 in a temporarily assembled state. By positioning and holding, the outer wall panels 3 can be easily assembled.

[0012]

According to the present invention, the upper wall 5 includes the mounting wall 7, the receiving wall 8, and the front wall 10 corresponding to the window sash frame 1 projecting outside (forward) from the outer surface of the outer wall panel 3. The drainer 4 is formed of a horizontally long strip, and the front wall 1
Since the lower end of the upper wall 5 is received and supported by the upper wall 5, the drainer 4 is supplied to all window sashes even when the shape and structure of the upper wall 5 or the inclination angle of the upper surface of the upper wall 5 are variously changed. It can be mounted on the frame 1 without any trouble. Since the draining member 4 and the caulking member 19 cooperate to perform waterproofing, a reliable waterproofing effect is obtained, and the reliability can be improved by maintaining the waterproofing function for a long time. Mounting wall 7, receiving wall 8, and front wall 1
0, the connecting groove 12 is formed, and the lower end of the outer wall panel 3 is fitted and mounted in the connecting groove 12, so that the lower part of the outer wall panel 3 can be held and fixed by the connecting groove 12, and the assembling of the outer wall panel 3 is facilitated. It is possible to prevent rattling due to loosening of the fastener 18 after construction.

Further, in the present invention, a step wall 20 is provided on the upper inner surface of the front wall 10 to secure a filling space for the caulking material 19 between the front wall 10 and the outer wall panel 3. Can be easily and reliably filled, and a high level of waterproofness can be obtained.
Since the exposed area of the caulking material 19 can be reduced, the appearance of the caulking material 19 can be minimized and the deterioration of the waterproof function can be well prevented.
