2. Description of the Related Art Outer wall panels such as brick tiles have recently been widely used as building exterior materials because of their excellent structure and aesthetic appearance. Since this kind of outer wall panel is provided as a standard length material of a predetermined standard, when using it as an outer wall material of a building, the units of this outer wall panel are arranged side by side, but from the joints. It is necessary to install it on the side of the furring strip with a joint for preventing the infiltration of water droplets such as raindrops.

As a structure of a joint sealing material for an outer wall panel, the fitting portion is arranged in a joint space formed between the opposed end faces of the outer wall panels which are conventionally arranged adjacent to each other and is fixed on the front side of the furring strip. The structure of the joint sealing material of the outer wall panel formed by the joiner material and the joint gasket material that is attached to the fitting portion of the joiner and is installed to seal the joint gap is used. There is. And its structure is that the joiner material is erected in parallel on the bottom plate, and the tip edges of a pair of side plates are bent inward to form a locking part, which is attached to the anchor lip part of the bottom part of the gasket material. A structure is known in which an upper joint sealing material and a lower joint sealing material provided on a leg portion of a gasket material are arranged in pressure contact with opposing end surfaces to seal a joint space.

[0004]

However, in such a sealing structure, the gasket material is fixed to the locking portion of the joiner material by systematically attaching to the anchor lip portion of the bottom portion of the gasket material. It is difficult to do so, and the gasket material may be displaced or installed at an angle, which may result in insufficient sealing.

Therefore, as a result of studying a sealing structure for making the fixing of the gasket material stronger and the sealing complete, the inventors of the present invention have determined that the joiner material and the gasket material have a specific structure, and thus the gasket material to be joined to the joiner material. It has been found that it is easy to insert, has good adhesion, and enables strong sealing.

And an outer wall panel formed by pressing the joint sealing material of the joint gasket material held by meshing with the joiner material to the opposite end surface of the outer wall panel forming the joint void portion. It is the structure of the sealing material for joints.

The structure of the joint sealing material of the outer wall panel of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a joint sealing structure according to the present invention, which is fitted into a joint void portion 3 formed between facing end surfaces 2 of outer wall panels 1 and 1 arranged adjacent to each other and a furring strip. It comprises a joiner material 5 provided on the front side of the material 4, and a joint gasket material 15 fitted to the inner surface of the joiner material so as to be in close contact with each other and seal the joint void portion 3.

The joiner member 5 is made of a thermoplastic material such as polyethylene or polypropylene, or a metal material such as aluminum. As shown in FIG. 2, the bottom plate 7 has a back surface contacting the furring strip 4 and a front surface serving as a water conduit 6. The bottom plate 7 is provided with a space for the insertion width of the bottom of the gasket material at the center of the front side of the bottom plate 7 so that the bottom plate is bent and bulged in the vertical direction of the front side. And consists of.

The inner plates 10 of the both side plates are provided with serrated notches 11 for engaging and closely contacting the gasket material for joints, and the upper part of the inner surface is provided with a taper 12 which serves as a guide for inserting the gasket material. It has a structure.

Since the joiner material is usually arranged between the adjacent outer wall panels, the bottom plate 7 extends to both outer sides of the side plate 8. However, depending on the position of use of the joiner material, the side plate is used in a state where the side plate is located at the end. In some cases, the notch 13 can be provided on the back side of the standing position of the side plate so that the bottom plate outside the side plate can be cut off.

Since the side plate 8 is formed by bending the bottom plate vertically in the front side, a space 14 is provided between the outer surface plate 9 and the inner surface plate 10. Therefore, even if the outer wall panel thermally expands or thermally contracts, it can be absorbed by the bent portion of the joiner material, and the adhesion of the gasket can be maintained.

On the other hand, the joint gasket material 15 is made of natural rubber,
A material having elasticity such as synthetic rubber or thermoplastic elastomer is used. However, since it is used outdoors, a material having excellent weather resistance and ozone resistance is preferable.

The structure is, as shown in FIG. 3, a body portion 16 and a plurality of joint sealing materials 17, 18 provided on both sides of the body portion 16,
It is formed with 19. Sawtooth notches 20 that engage with the inner surface of the joiner material side plate are provided on both side surfaces of the lower portion of the body portion, and are closely fixed by being inserted into the joiner material. The joint sealing material is installed on both side surfaces of the body in several stages vertically, but the joint sealing material 19 at the lowermost stage needs to be positioned higher than the height of the joiner material both side plates 8. Joint gasket material 15
When it is inserted into the joiner material, the joint sealing material has a sufficient length so that it can be pressed into contact with the opposite end surface of the outer wall panel. And the both ends are pressed against the opposite end faces of the outer wall panel. Since the gasket material is made of an elastic body, it is pressed against the opposing end surface of the outer wall panel by its restoring force, and the joint void can be firmly sealed.
