DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an upper portion of a sash to be mounted on an outer wall surface, the structure being capable of easily ensuring watertightness.

[0002]

2. Description of the Related Art Conventionally, when a sash is mounted on an outer wall surface, a structure in which an upwardly protruding mounting piece abuts on the outer wall surface of the sash is attached to the outer wall surface, and the outdoor side of the mounting piece is covered with a cover. It has been used conventionally. In this structure, since the cover does not have a function to keep water tight, rainwater flowing on the outer wall surface flows into the cover from the gap between the cover and the outer wall surface, and the momentum that flows on the outer wall surface, It flows into the contact area.

[0003]

In recent years, in order to improve the appearance of a building, it has become necessary to use an exterior material having a deeper uneven pattern than that conventionally used. At this time, as the unevenness of the pattern formed on the outer wall surface increases, the gap formed between the outer wall surface and the cover increases,
The amount of rainwater flowing directly into the contact between the mounting piece and the outer wall surface increases. Therefore, in the case of using an exterior material having a deep uneven pattern, in the conventional configuration, rainwater flows in from the mounting portion on the upper portion of the sash, and the rainwater passes through the water stop portion provided between the mounting piece and the outer wall surface. Then, rainwater may flow into the room or the inside of the outer wall.

[0004]

SUMMARY OF THE INVENTION According to the present invention, an upwardly protruding mounting piece is mounted on an upper surface of a sash by abutting against an outer wall surface, and a contact portion between the mounting piece and the outer wall surface is mounted on the outer wall above the mounting piece. Attach a drainer protruding outdoors to cover,
Attach the cover so as to cover the drainer and the outdoor side of the upper end of the mounting piece. According to this configuration, the rainwater flowing down the outer wall is
Since it does not flow down to the outdoor side due to drainage and does not directly flow into the contact part between the mounting piece and the outer wall surface, even if the unevenness of the pattern of the exterior material becomes large and the amount of rainwater flowing into the cover increases, A large water pressure is not applied to the contact portion on the outer wall surface, and the watertightness of the contact portion can be easily maintained.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a structure for attaching the upper end of the sash 1 to the outer wall. At the upper end of the sash 1, a mounting piece 2 protruding upward is formed. A concave portion extending in the horizontal direction is formed on the outer wall surface side of the mounting piece 2, and a watertight material 3 made of foamed rubber is disposed in the concave portion. A base material 4 having a flat surface is attached to a surface of the outer wall surface to which the attachment piece 2 comes into contact. Attachment piece 2 on the surface of base material 4
Are screwed in so as to penetrate the surface of the mounting piece 2 and the watertight material 3, and the upper end of the sash 1 is fixed. At this time, since the surface of the base material 4 is flat, the watertight material 3 is in close contact with the surface of the base material 4, thereby ensuring watertightness at the contact portion between the mounting piece 2 and the outer wall surface. Also,
Since the screw 5 penetrates through the watertight material 3, water leakage from the screw hole can be prevented.

[0006] A horizontal joint 6 is formed between the base material 4 and the exterior material located above the base material 4.
Is filled with a sealing agent made of denatured silicon and the like. Further, in order to ensure watertightness between the lower surface of the rear end of the drainer 7 and the upper end of the base material 4, a watertight tape 8 made of butyl rubber tape or urethane foam tape is provided on the lower surface of the rear end of the drainer 7. Installed. The drainer 7 is adhered and fixed by curing the sealing agent filled in the joint 6. The drainer 7 has a horizontal rear end inserted into the joint 6,
The main body of the drainer 7 is downwardly inclined, and the lower end of the drainer 7 is slightly suspended. Drainer 7 is sash 1
It is attached to extend from one end to the other end of the upper part.

A horizontal fitting groove is also formed on the surface of the mounting piece 2. The base of the cover 10 is fitted into the fitting groove. In the vicinity of the surface of the fitting groove, the surface plate of the mounting piece 2 slightly projects from the side wall of the fitting groove toward the inside of the groove, so that the front end of the base of the cover 10 is easily engaged.

The cover 10 includes a cover body 10a formed of a vertical surface and a horizontal piece bent from the upper end thereof toward the outer wall side, and a cover base 10b located below the cover body 10a. The cover 10 is made of the same aluminum alloy as that of the sash 1, and the surface thereof is painted similarly to the sash 1. The upper end of the cover body 10a is attached so as to contact the outer wall. A pair of fitting pieces 11 that fit into the fitting grooves of the mounting pieces 2 of the sash 1 protrude from the back surface side of the cover base 10b, and the tips are slightly close to each other so that the fitting can be easily performed. I have. In addition, cover body 1 from the base
The surface of Oa is located on the outdoor side, a space is formed between the base material 4 of the outer wall and the cover body 10a, and the drainer 7 is located in the space. Therefore, since the drainer 7 is completely covered by the cover main body 10a, the drainer 7 is not exposed to the outside, the aesthetic appearance can be maintained, and the drainer 7 can be protected.

A vertical joint pattern whose bottom is indicated by the dotted line 9 is formed on the surface of the exterior material, and a gap is formed between the upper end of the cover 10 and the outer wall at the joint pattern. Therefore, the rainwater travels along the outer wall, mainly through the joint pattern, and enters the inside of the cover 10, but flows down in the outdoor direction by the drainer 7. As a result, rainwater does not flow directly into the contact portion between the mounting piece 2 of the sash 1 and the exterior material, and high-pressure rainwater does not flow into the contact portion, so that watertightness at this contact portion is easily ensured. can do. The water flowing into the cover 10 flows through the cover 10 and is discharged from both ends of the cover 10 in the horizontal direction.

In this embodiment, the drainer 7 is attached by inserting its rear end into the joint 6 of the outer wall. However, the drainer 7 may be attached by, for example, bonding to the outer wall.

[0011]

According to the present invention, an upwardly projecting mounting piece is mounted on the outer wall of the sash by abutting against the outer wall surface. The outer wall above the mounting piece covers the upper part of the sash so as to cover the contact portion between the mounting piece and the outer wall surface. The rainwater that flows down the outer wall surface flows down to the outdoor side by draining, and the rainwater that flows down the outer wall is directly attached to the contact between the mounting piece and the outer wall surface. Even if the water does not flow in and the unevenness of the pattern of the exterior material becomes large and the amount of rainwater that flows into the cover increases, large water pressure is not applied to the contact part between the mounting piece and the outer wall surface, and the water tightness of the contact part is improved. Can be easily kept.
