Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a so-called double-seal joint gasket, which is a combination of two seal members to be inserted into joints formed at joints of outer wall panels of buildings. Is.

<Prior Art> A conventional gasket used as a joint gasket to be inserted into a joint formed in a joint portion of an outer wall panel of a building is
As shown in the figure, a pair of rubber or rubber-like elastic members having a D-shaped cross section are used to form water-stop members 7 and 7 at the joints of outer wall panels 5 and 5 via an adhesive material 1b attached to a flat portion. There is one in which the joints 6 are watertightly sealed by adhering the end faces of the joints 6 facing each other and making their curved surface portions elastically contact each other. The surface of the curved surface is formed with a film 7a of a rubber or a rubber-like elastic material having a white color or the same color as the outer wall panel 5. In addition, the water blocking members 7,7 are usually the outer wall panels 5,5.
By projecting the vicinity of the outer surfaces of the end surfaces of the joint portion facing each other, the main portion 6b of the joint 6 at the back of the throat 6a formed near the outer surface is mounted.

As shown in FIG. 3, this joint gasket has a recess 8 between curved surface portions, which is seen as a shadow from the outside, impairing the external appearance, and a portion that exerts a water blocking function is one portion where the curved surface portion is in elastic contact. However, there are two problems of insufficient water stopping function.

<Problems to be solved by the invention> Since the conventional joint gasket has the above-mentioned problems, it is expected that a joint gasket which has no shadow, has an excellent appearance, and has a high water blocking function is provided. .

An object of the present invention is to provide a joint gasket that solves the above problems.

<Means for Solving the Problems> Description will be made with reference to FIGS. 1 and 2. In order to achieve the above object, a joint gasket according to the present invention comprises a pair of rubbers or rubber-like elastic bodies, at least one of which has a D-shaped cross section, and which has elastic members 1 and 3 elastically contacting each other.
It is adhered to the end faces of the joints 6 formed at the joints of the outer wall panels 5 and 5 facing each other via b and 3a, and at the same time, from one side to the other side A pair of decorative water-stop lips 2,4 which extend toward the member and which are formed on the outer surface with a white or rubber or rubber-like elastic film 2a, 4a of the same color as the outer wall panel 5 and which are overlapped and elastically contact with each other
Is a combination of.

<Operation> In the joint gasket constructed as described above, the pair of decorative and waterproofing lips 2 and 4 are overlapped with each other and elastically contacted with each other, and the outermost side is made of a white or same color rubber or rubber-like elastic body. Since it is covered with the films 2a and 4a, the appearance is improved without a shadow when viewed from the outside. Further, since the joint 6 is doubly sealed by the elastic contact of the pair of water blocking members 1 and 3 and the pair of decoration and water blocking lips 2 and 4, the water blocking function is remarkably improved.

<Example> 1 is a waterproof member having a skeleton made of black rubber or a rubber-like elastic body and having a D-shaped cross section, 1a is a white-colored film formed on the surface of the curved surface or a film of the same color as the outer wall panel, 1b Is an adhesive material attached to the flat surface portion, and 2 is a decorative and waterproof lip extending from the outer surface side end portion of the water blocking member 1 in a direction perpendicular to the flat surface portion. A film 2a having a white color or the same color as the outer wall panel is formed on the surface.

The other water-stop member 3 has only a flat surface portion and no curved surface portion, and a decorative and water-stopping lip 4 extending in a right angle direction is coupled to the outer end portion of the flat surface portion, and a white or outer wall panel is formed on the outer surface. The film 4a of the same color is formed.

The shape of the joint 6 to which the pair of water blocking materials 1 and 3 configured as described above is attached is such that the vicinity of the outer surface of the joints of the outer wall panels 5 and 5 is protruded in the vicinity of the outer surface. A throat 6a is formed in the throat 6a, and a wide main portion 6b is formed in the back of the throat 6a.
Is formed.

Before mounting, the outer wall panels 5 and 5 are bonded to the water-stopping members 1 and 3 in advance, and the outer wall panel 5 to which the D-shaped water-stopping member 1 is bonded is first stretched, and then only the flat portion is attached. By pushing the outer wall panel 5 to which the water blocking member 3 is adhered, the water blocking members 1 and 3 are elastically contacted with each other, and the decorative and water blocking lips 2 and 4 are overlapped and elastically contacted.

Next, the operation will be described. The joint gasket constructed as described above has a pair of decorative and water-stop lips 2 and 4 overlapping each other and elastically contacting each other, and the outermost outermost rubber or rubber-like elastic body film 2a of substantially the same color, Since it is covered with 4a, the appearance is improved without a shadow when viewed from the outside. Further, since the joint 6 is doubly sealed by the elastic contact of the pair of water blocking members 1 and 3 and the pair of decoration and water blocking lips 2 and 4, the water blocking function is remarkably improved.

<Effects of the Invention> Since the present invention is configured as described above, the waterproof function and the appearance are significantly improved as compared with the joint gasket having the conventional shape.
