Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watertight structure of a corner portion which has a simple structure and good watertightness.

[0002]

2. Description of the Related Art As means for ensuring the watertightness in the clearance between the corners where the ends of the exterior materials arranged at a substantially right angle meet, a wet process of filling a caulking material or a long elastic method is used. There is a dry-type construction in which a body gasket is attached, but in recent years, dry-type construction has been widely adopted. However, the gasket formed by the elastic member may be twisted or
Twisting is often found, which causes the watertightness to be reduced and causes water leakage.

Further, in Japanese Patent Laid-Open No. 64-58737, as a joint structure of an entering corner, a backup material is filled in a deep part of a corner gap portion of an entering corner of a wall panel arranged at a substantially right angle, It is disclosed that a dry joint material, which is composed of a joint material and a joint cover connected to the joint material, is inserted into the corner gap portion as a backup material.

However, this is one in which the wall panel is first built and the dry joint material is inserted into the gap later, and the joint material is merely inserted between the inclined surfaces of the face plate. Therefore, there is a fear that it shifts back and forth, and further there is a fear that the elastic foam provided on both sides of the joint material body itself shrinks over time, and these things can be seen from between the joint material end and the inclined surface of the face plate. May cause water leakage.

The first member 8 of the outer gasket 7 has a main body having a substantially rectangular shape in a plan view, and one long side of the main body located on the indoor side is a mounting surface 8a on the frame body, and a surface on the outdoor side. A connecting groove portion 8b is formed on the other long side surface, and left and right elastic bending fins 8c, 8c are formed by extending left and right end portions of the other long side surface while curving toward the indoor side. Has been done.

The second member 9 is formed in a substantially T shape in a plan view from the joint portion 9a and the connecting projection 9b. The left and right end portions of the joint portion 9a of the second member 9 are formed in a fin shape so as to be slightly warped toward the outdoor side. Further, the connecting groove portion 8b of the first member 8 and the connecting protrusion portion 9b of the second member 9 are formed in a shape that engages with each other, so that the second member 9 fitted in the first member 8 can be easily removed. There is no such thing. The outer gasket 7 is formed of an elastic member such as synthetic rubber or elastic synthetic resin, but the material thereof is not particularly limited and is widely selected from known members usually used for gaskets.

As is apparent from FIG. 1, when the outer gasket 7 is installed in the inner corner space, the curved portions of the left and right elastic bending fins 8c, 8c of the first member 8 are covered with the exterior materials 1, 1.
And the fin-shaped ends of the joint 9a of the second member 9 are elastically contacted with the inclined surfaces 3 and 3 formed on the exterior material end surfaces 2 and 2. And closes the opening 5. Further, an inner gasket 6 is provided between the left and right end portions of the frame body 4 and the inner side surfaces of the end portions of the exterior materials 1 and 1.
Is provided and functions as a secondary seal. still,
Depending on the shape of the exterior material, the shape of the frame, the configuration of the corners, etc., the internal gasket is not necessarily used, but in order to improve the watertightness, the internal gasket is used as the secondary seal. It is desirable to do.

Now, in constructing the watertight structure of the entry corner constructed as described above, first, the outer gasket 7 and the inner gasket 6 are attached to the frame 4 erected on the corner of the building.

The end faces 2 and 2 are elastically contacted with the curved portions of the elastic bending fins 8c and 8c of the first member 8 of the outer gasket 7, respectively, to be built.

Since the first member 8 attached in advance is sandwiched between the end faces 2 and 2 of the exterior materials 1 and 1 that meet through the curved portions of the elastic bending fins 8c and 8c, the first member 8 is formed. Not only does it move or come off,
The curved portions of the elastic bending fins 8c, 8c are pressed against the end faces 2, 2 of the exterior materials 1, 1 to prevent water leakage. Elastic bending fins 8c, 8c of the first member 8
Is curved toward the inside of the room, the end faces 2 and 2 of the exterior material come into contact with the curved portions of the elastic bending fins 8c and 8c in a smooth manner when the exterior materials 1 and 1 are installed, and The curved fins 8c, 8c are not twisted.

Next, the connecting projection 9b of the second member 9 is first
When it is fitted into the connecting groove portion 8b of the member 8, the first member 8 is slightly expanded in the left-right direction, and the curved portions of the elastic bending fins 8c, 8c elastically contacted with the end faces 2, 2 of the exterior material are directed toward the indoor side. It is pressed a little, and further pressed against the end faces 2 and 2 to make the watertightness stronger. Further, since the first member 8 is pressed against the end faces 2 and 2 of the exterior material via the elastic bending portions of the elastic bending fins 8c and 8c, the first member 8 has a certain width, and the end faces 2 and 2 of the exterior material have a certain width. Even if the first member 8 is slightly displaced, the watertightness is not impaired. On the other hand, the second member 9
The left and right end portions of the joint portion 9a are elastically contacted with the inclined surfaces 3 and 3 formed at the outdoor side end portion of the exterior material end surface to function as a primary seal member.

[0015]

As described above, the present invention provides a watertight structure of an entering corner in which a long gasket is mounted in the entering corner space where the ends of the exterior materials arranged at substantially right angles meet each other.
