DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint type gasket for an architectural outer wall having a partially different color tone.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 2, a joint 2 formed at a connecting portion between outer walls 1 and 1 extending to the outside of a building has a joint to prevent water from entering the inside of the building. A cover portion 6a for covering the portion 2 from the outside, a central leg portion 6b joined to the cover portion 6a in a T-shape, and a plurality of seal lips 6c extending from both sides of the leg portion 6b toward the end surfaces of the outer walls 1, 1. The fixed gasket 6 is fitted.
The surface of the outer wall 1 has a main surface layer 1a of the first color P and a second color Q
In this case, the color of the cover surface 6d of the cover base 6e and the cover surface 6d of the fixed gasket 6 is a single color, but is the same as the color P of the main surface 1a of the outer wall 1. The main surface 1 of the outer wall 1
The feeling of incompatibility with a is minimized.

However, when the fixed gasket 6 is attached to the joint portion 2 of the outer wall 1, since the surface layer 6d of the cover portion 6a is a single color P, the outer wall 1 of a plurality of colors P and Q is also used.
There is a problem that the surface has a feeling of strangeness and the appearance is not good. In order to solve this, the cover part 6
Although it is conceivable to make the color tone pattern of the surface layer 6d of a the same as the color tone pattern of the surface of the outer wall 1, there is no effective means for realizing it.

[0004]

The problem to be solved is that the color pattern of the surface layer 6d of the cover portion 6a of the conventional fixed gasket 6 is made equal to the color pattern of the surface of the outer wall 1 to effectively eliminate uncomfortable feeling. There is no means.

A description will be given with reference to FIGS. The present invention relates to a fixed gasket 3 which is fitted into a joint 2 formed at a connecting portion between outer walls 1 and 1 having a color tone partially different from the outside of a building to prevent water from entering the inside of the building.
, The surface layer 3d of the cover portion 3a, which is the same as the main color P of the outer wall 1 and covers the joint portion 2 from the outside, is partially removed, and the cover portion of the same single color Q as the sub-color Q of the outer wall 1 is removed. In exposing the base portion 3e and matching the color tone pattern of the cover portion 3a with the color tone pattern of the outer wall 1, the surface layer 3d of the cover portion 3a of the gasket molded product immediately after extrusion molding is partially rolled with a roll having a partially sharp projection. And the step of exposing the cover base 3e, and the step of vulcanizing the molded product obtained by partially scraping the cover surface layer 3d to impart elasticity.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS To explain the embodiment, reference numerals 1 and 1 denote outer walls stretched outside the building, and the color tone pattern on the surface is partially different in a patchy manner. That is, the main color P
The main surface layer 1a and the different color particles 1b of the sub color Q are combined. Reference numeral 2 denotes a joint formed at the connecting portion between the outer walls 1 and 1, and reference numeral 3 denotes a fixed sealing material 3 made of rubber or a rubber-like elastic body fitted to prevent water from entering the inside of the building. A central leg portion 3b is joined in a T-shape to a cover portion 3a that covers the outer portion 2 from the outside, and a plurality of seal lips 3c are branched from both sides of the central leg portion 3b toward the end surfaces of the outer walls 1 and 1. The cover portion 3a includes a cover base 3e of the second color Q and a cover surface layer 3d of the first color P. The second color Q of the cover base 3e is the outer wall 1
, And the first color P of the cover surface layer 3 d is the same as the main color P of the surface of the outer wall 1. The cover surface layer 3d is partially patchy removed, the cover base 3e is exposed, and the color tone pattern of the cover portion 3a is matched with the color tone pattern of the outer walls 1 and 1. In manufacturing the fixed gasket 3, first, a cover portion 3 of a gasket molded product immediately after extrusion molding is formed by a roll having a partly sharp projection.
a of the cover surface layer 3d,
The cover base 3e is exposed, and then the molded product is vulcanized to impart elasticity.

The cover base 3e, the center leg 3b,
It is convenient to manufacture the seal lip 3c if the same color is used.

The operation of the standard gasket 3 thus obtained is such that the central leg portion 3b and a plurality of seal lips 3c are fitted into the joint portions 2 of the outer walls 1, 1 and the joint portion 3a is joined by the cover portion 3a. When the portion 2 is covered, both the color tone patterns of the cover portion 3a and the outer walls 1 and 1 match, the sense of incongruity is eliminated, and the appearance is significantly improved.

[0009]

Since the present invention is configured as described above,
The color tone pattern of the cover portion 3a and the color tone pattern of the outer walls 1 and 1 match each other, so that a sense of incongruity is eliminated and a good-looking fixed-type gasket can be easily manufactured.
