It is necessary to install the joint on the side of the hull material with a joint for preventing water liquid such as raindrop from entering.

[0003] As a structure of a joint sealing material for an outer wall panel, a fitting portion thereof is arranged in a joint space formed between opposed end faces of a conventionally arranged outer wall panel, and is fixed to the front side of the rim material. The structure of the joint sealing material of the outer wall panel formed by the jointer material and the joint gasket material which is held at the fitting portion of the joiner material and is attached to seal the joint gap is used. I have. And the structure is a joiner material having a bottom plate abutting on the body edge material, a pair of side plates erected in parallel at the center of the front side of the bottom plate with an insertion width of the gasket material, and both side plates thereof A gasket material having a plurality of pairs of joint sealing materials provided on both sides in upper and lower stages from the upper portion thereof, and a gasket material made of an elastic material is provided between both side plates of the joiner material. When inserted, the joint sealing material curves upward and comes into contact with the facing end surface of the outer wall panel,
The end face is strongly pressed by the force pushed outward by the restoring force, and the joint gap is firmly sealed. One example of the joint sealing structure will be described with reference to FIG.

[0006] In FIG. 6, a joiner which is fitted into a joint space 14 formed between opposed end faces 12, 12 of adjacent outer wall panels 11, 11 and is provided on the front side of a body material 15. The joint material is made up of a material A and a joint gasket material B which is fitted and engaged with the inner surface of the joiner material to seal the joint gap 14.

The joiner material A has, for example, a structure as shown in FIG.
And a pair of side plates 23, 23 erected in parallel with a gap of the insertion width of the bottom portion of the gasket material provided at the center on the front side of the bottom plate. The side plate 23 is formed by bending and protruding the bottom plate in the vertical direction on the front side, and includes an outer plate 24 and an inner plate 25, and a space 26 exists between them.

In order to fit the gasket material between the two side plates of the joiner material, serrations 27 are provided on the inner surfaces 25 of the both side plates, and both sides of the lower portion of the body of the gasket material are also provided on the inner surfaces of the joiner material side plates. An engaging serration 35 is provided to fix the joiner material and the gasket material, or the inner surfaces of both side plates are bent inclining inward, and both side surfaces of the gasket body are locked to the inner surfaces of the joiner material side plates.

[0009]

However, even if the joint gap is sealed with such joint sealing material, the outer wall panel is used outdoors and is exposed to severe conditions, so that the temperature of the outer wall panel changes drastically, and the outer wall panel is exposed to severe conditions. When heat shrinkage occurs, the gap between the opposing outer wall panel end faces is widened, and therefore both side plates of the joiner material are also pulled outward and the gap is widened, so that the adhesion between the gasket material and the joiner material and the outer wall panel is weakened. Therefore, the sealing force is weakened, and it is impossible to prevent water from entering. In such a state, the gasket material can be easily peeled off with a weak force, so that the gasket material is often peeled off due to mischief of children.

In order to solve these problems, the inventor of the present invention can maintain the sealing force of the gasket material without deforming the joiner material even when the outer wall panel is thermally contracted. As a result of studying the method of protecting the joint sealing material, it was found that the object can be achieved by fitting and fixing a small member having a specific structure described below to the end of the joint sealing material.
