BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint sealing structure for outer wall panels, and more particularly, to prevent water from entering into a building from joint gaps formed between adjacent outer wall panels. The present invention relates to a joint sealing structure for outer wall panels, which is composed of a joiner material and a gasket material.

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

[0004]

However, in such a sealing structure, the joint sealing is bent upward by pushing the lower joint sealing material and the upper joint sealing material of the gasket material into the voids. Although it is due to the close contact with the outer wall panel, the pressing force against the outer wall panel was not so great, so the sealing could not be said to be sufficient.

The present inventors have studied a sealing structure for more complete sealing, and as a result, by fitting a joiner material into a gasket material and providing a force for expanding the gasket material to the outside. , Found that strong sealing is possible.

DISCLOSURE OF THE INVENTION The present invention seals a joint void formed on an opposite end surface of an outer wall panel disposed adjacent to the front side of a furring strip, so that the joiner is fitted into the joint void. In a joint sealing structure of an outer wall panel consisting of a material and a gasket material for joints, the joiner material is a bottom plate that abuts the furring strip, and the front plate center portion of the bottom plate is parallel to the bottom plate along the length direction of the bottom plate. A pair of standing side plates, and a fitting plate standing upright in the middle of the both side plates and having a fitting protrusion for gasket locking at the top, a joint gasket material is formed in the center upper part of the joiner material. A leg portion having a hollow portion that fits into the fitting plate, an upper joint sealing material provided on the upper end portion of the leg portion to seal the joint space, and a lower joint portion provided on the lower portion thereof. Formed with encapsulant, joiner material For joints of outer wall panels, in which the upper joint sealing material and the lower joint sealing material of the joint gasket material, which are fitted and held, are arranged in pressure contact with the facing end faces of the outer wall panel forming the joint gaps. It is a sealing structure.

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 shows facing end surfaces 2 of outer wall panels 1 and 1 arranged adjacent to each other.
The furring material 4 fitted in the joint void 3 formed between the two
The joiner member 5 provided on the front side of the joint member 5 and the joint gasket member 13 fitted to the joiner member 5 to seal the joint gap portion 3 are attached.

The joiner material 5 is made of a material such as aluminum. As shown in FIGS. 2 to 4, a bottom plate 7 having a back surface abutting the furring strip 4 and a front surface serving as a water conduit 6, and a front center of the bottom plate 7. With a space corresponding to the width of the joint space,
A pair of side plates 8 and 8 which are erected in parallel along the length direction of the bottom plate, and a constricted fitting projection structure which is erected in the middle of the both side plates and whose top is locked to the gasket material 13. It is formed from the fitting plate 10 which is 9.

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 where the joiner material is used, the side plate is used in a state where the side plate is located at the end. In some cases, the notch 11 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 (FIG. 2). Further, the upper end of the side plate 8 is preferably provided with a notch 12 inside so as to serve as a guide for insertion into the gasket material.

The shape of the joiner material 5 may be as shown in FIG. 2, but as shown in FIG. 3, the fitting plate is easy to insert the gasket material and to increase the force for expanding the gasket material to the outside. A taper is preferred. Further, as shown in FIG. 4, the fitting projection structure at the top may be changed.

On the other hand, the joint gasket material 13 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.

As shown in FIGS. 6 to 8, the structure is such that a leg portion 15 having a cavity portion 14 which fits in a fitting plate 9 of a joiner material in the central upper portion, and an upper joint seal winged on the upper portion. A stopper 16 and a lower joint sealing material 17 provided below the stopper,
18 and. The cavity 14 is a fitting plate 9 of joiner material.
It is to be engaged with the joiner material and locked with the joiner material.
~ The joiner material as shown in Fig. 4 can have various shapes, for example, as shown in Figs. Further, in order to increase the force of expanding the gasket material to the outside, the joiner material of FIG. 3 and the gasket material of FIG. 5 can be combined, and when the gasket material is a flexible material, FIG.
As described above, only the portion corresponding to the fitting projection 9 on the top of the fitting plate may be the cavity 14, and the lower part may be the one in which the left and right legs 15 are in close contact.

The lower end of the leg portion of the gasket material is preferably provided with a notch portion 19 inside so as to serve as a guide when the joiner material is inserted. As a modification of the notch 19, the structure shown in FIGS. 8 and 9 may be used. The lower end of the leg portion of the gasket material in FIG. 8 is entirely a notch 19 toward the inside, so that the joiner material can be easily inserted, and the state of the gasket material after insertion is as shown in FIG. Are spread so that the lower ends of the legs are parallel to the bottom plate of the joiner material, and both can be brought into close contact with each other.

The upper joint sealing material 16 provided on the upper portion of the leg portion 15 and the lower joint sealing material 17 provided on the lower portion of the leg portion 15 when the joint gasket material 13 is fitted with the joiner material. , Both of which are opposite end faces 2, 2 of the outer wall panel 1, 1.
It is long enough to be placed under pressure. The lower joint sealing material may be a pair, but normally, in order to improve the sealing of the joint space, it is preferable to provide two pairs (17 and 18) or more as shown in FIGS. At this time, it is necessary to attach the lowermost lower joint sealing material to a position higher than the height of both side plates of the joiner material.
