Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a joint gasket to be inserted into a joint formed in a joint portion of an outer wall panel of a building.

<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 FIGS. 4 and 5, a flat plate-like surface portion 11 that covers the joint 8 and the surface portion 11 that forms a T-shape together with the surface portion 11 are formed.
A leg part that vertically projects from the midpoint of 11 and is inserted into the joint 8.
12 and a leg portion 12 of the outer wall panel 4 forming a joint 8 and extending toward the end surface of the outer wall panel 13 for elastic contact, and the outer surface of the surface portion 11 is the same color as the outer wall panel 4 (white) There is a rubber or rubber-like elastic body 11a covered with the above. When the joint gasket 10 is mounted on the joint 8, the joint 8 has a width W which is usually different, and when the width W is larger than the standard size, as shown in FIG. There is a problem in that it tends to cause a so-called rolling phenomenon, which deteriorates the appearance of installation, and that the water-stopping lip portion 13 does not make elastic contact with the end surface of the outer wall panel 4 and the water-tight function is significantly impaired. There is.
Numerals 6 and 6 are vehicles for sticking the outer wall panels 4 and 4, and 6a is a gap between them, and the gap 6a is separately filled with a secondary water blocking material 7.

<Problems to be solved by the invention> Since the conventional joint gasket has the above problems, it is expected that a joint gasket that does not cause the rolling phenomenon will appear.

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 has a flat plate-like surface portion 1 for covering a joint 8, and a vertical projection from a midpoint of the surface portion 1 so as to form a T-shape with the surface portion 1. It is composed of a base leg portion 2a to be inserted into the joint 8 and a water stopping lip portion 3 which extends from the base leg portion 2a toward the end surface of the outer wall panel 4 forming the joint 8 and is elastically contacted, and particularly the surface portion 1 The base leg portion 2a is extended beyond the farthest water stop lip portion 3 to form an extension leg portion 2b, and two stops extending toward both sides of the extension leg portion 2b adjacent to the farthest water stop lip portion 3b. The water / stopper lips 5a, 5a and the fall prevention lips 5b, 5b are formed on both sides of the distal ends of the extension legs 2b so as to extend in a direction opposite to the water / stopper lips 5a, 5a and to the end.

<Operation> Since the present invention is configured as described above, when the joint gasket 9 is inserted into the joint 8 and the gap 6a between the joint bodies 6 and 6 that follows it, the two waterproof / stopper lip 5a, 5a joints 8
The surface part 1 is pressed so that it spreads over the surface of the inner body 6,6.
The farthest water stop lip part 3 is pressed against the surfaces of the bodies 6,6 at the back of the joint 8, and two water stop and stopper lips 5a, 5
a is spread on both sides, and the fall prevention lips 5b, 5b formed at the tips of the extension legs 2b are inserted into the gaps 6a between the bodies 6, 6 and elastically contact the bodies 6, 6, thereby forming joints. The tendency of the gasket to incline with respect to the insertion direction is suppressed, the surface portion 1 and the water stop lip 3 are naturally positioned symmetrically with respect to an axis parallel to the insertion direction, and the surface portion 1 and the water stop lip 3 are All the tips are in elastic contact with the end surface of the outer wall panel 4, and neither the appearance nor the watertight function is impaired.

<Example> An example will be described with reference to FIGS. 1 and 2.
Reference numeral 1 denotes a surface portion, the outer surface of which is coated with rubber or a rubber-like elastic body 1a. 2a is a base leg portion that extends vertically from the midpoint of the surface portion 1 integrally, and 3 is a branch part from the base leg portion 2a, which extends to the end face of the outer wall panel 4 forming the joint 8 and is elastically contacted with a water stopping lip portion. Then, a bridge 3c is provided between the adjacent rips 3a and 3b to provide rigidity. 5a, 5a are two water-stop and stop-per rips that spread out on both sides of the extension leg 2b adjacent to the farthest water-stop lip 3, and the width between the tips is larger than the minimum width W of the joint 8. It has no dimensions. Reference numerals 5b and 5b are fall prevention lips formed on both sides of the tip of the extension leg portion 2b, and extend to the end spread in the opposite direction to the water-stop / stopper lips 5a and 5a.

Next, the operation will be described. Since the present invention is constructed as described above, by inserting the joint gasket 9 into the gap 6a between the joint 8 and the driving bodies 6,6, the extension adjacent to the water stop lip portion 3 farthest from the surface portion 1 is extended. Two sheets of water stop and stopper lip 5 formed so as to spread out on both sides of the leg 2b
The a and 5a are pressed against the vehicle bodies 6 and 6 at the back of the joint 8, the two water stopping and stopping stopper lips 5a and 5a spread to both sides, and the fall prevention lips 5b and 5b formed at the tips of the extension leg portions 2b. Vehicle 6,6
Of the joint 6 is inserted into the gap 6a of the joint 6 and elastically contacts the bodies 6 and 6 to suppress the tendency of the joint gasket 9 to incline with respect to the insertion direction, and the surface portion 1 and the water stop lip portion 3 are naturally parallel to the insertion direction. It is located relative to the virtual center line, and each tip is in elastic contact with the end surface of the outer wall panel 4, and neither the appearance nor the watertight function is impaired.

Further, even if the water stop lip portion 3 closest to the surface portion 1 may be seen from the outside due to the variation of the joint width W, the tip surface side of the outer wall panel 4 is made of rubber or a rubber-like rubber of the same color (white type). Since the elastic body 3d is covered, it does not give a strange appearance.

<Effect of device> Since the device of the present invention is configured as described above, when the joint gasket 9 is inserted into the gap 6a between the joint 8 and the driving bodies 6,6, the joint is always placed on the virtual center line parallel to the insertion direction. The watertight function is improved because the postures of symmetrical positioning are maintained.
Furthermore, the secondary waterproof material can be eliminated.
