Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel joining structure, and more particularly to a structure of a packing material inserted into a joint between panels.

[0002]

2. Description of the Related Art Conventionally, when a plurality of panels are joined to form an outer wall of a building, a convex portion is provided at one end of one adjacent panel, and the convex portion is fitted to one end of the other panel. By providing a concave portion and fitting the convex portion of one panel into the concave portion of the other panel, the ends of the panels are joined to each other.

[0003]

However, in the conventional concave-convex fitting structure, if it is attempted to eliminate the gap between the convex portion and the concave portion, the convex portion becomes difficult to be inserted into the concave portion, and conversely, the insertion becomes easy. If this is attempted, a gap is formed between the convex portion and the concave portion, and the sealing property (waterproofing property) is impaired. As a result, it is difficult to satisfy both the fitting property and the sealing property.
In particular, in order to absorb the width tolerance of the panel, it is necessary to adjust the joint width, but if the joint width is to be widened, the insertion depth of the convex portion must be reduced, and in this case, the seal is required. However, the joint width was limited, so that the joint width was limited. In addition, it is necessary to separately apply caulking to the joints between the panels, not only is the work of applying the caulking agent troublesome, but the construction is easily affected by the weather, and the caulking agent takes time to dry,
There are also problems such as unevenness of the surface of the caulking agent resulting in poor finish and waterproofness being impaired due to variations in the amount of caulking and deterioration of the caulking agent.
In addition, when the conventional uneven fitting portion has a waterproof structure using a packing material, it is necessary to interpose a packing material between the concave portion and the convex portion when connecting the panel. However, there was a problem that the packing material could not be attached, and the retrofitting method of the packing material could not be adopted. In addition, in the conventional concave-convex fitting method, it is necessary to connect a plurality of panels in order to construct a wall or the like.For this purpose, for example, a part of the wall is left as a working space, and finally, a working space is left. There is also a problem that a retrofitting method such as fitting one panel cannot be adopted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional example, and has as its object to facilitate the joining between panels and to provide excellent waterproofness, and to allow the joint width to be adjusted freely. No need for conventional caulking treatment, and a good finish can be obtained in a short time without being affected by the weather.In addition, the packing material can be retrofitted after panel installation, greatly improving the installation efficiency. An object of the present invention is to provide a panel joining structure that can be made to work.

[0005]

According to the present invention, a first groove 3 is formed at one end of one adjacent panel, and a first groove 3 is formed at one end of the other panel. A second groove 4 facing the first groove 3 is formed, and a packing material 5 is interposed between the first and second grooves 3, 4, and the packing material 5 extends from the joint 7 between the panels. First and second concave grooves 3,
4, a plurality of fin pieces 11 projecting from both sides of the core 13, each end of which is in elastic contact with each inner surface of the first and second concave grooves 3, 4; Is characterized in that it is integrally formed with the closing portion 12 that closes the joint. With such a configuration, the joint portion 7 is closed by the closing portion 12 so that the core portion 13 with the fin pieces 11 can be formed. The first and second concave grooves 3 and 4 are fixed without being inclined or displaced, and a sufficient water stopping effect by the packing material 5 can be obtained. In addition, since the conventional caulking process is not required, the construction can be performed easily and at low cost in a short time without being affected by the weather, and the finish and the waterproofness are improved. After the panel is installed, the packing material 5 can be attached to the joint 7 by inserting it. Further, by simply changing the dimensions of the packing material 5 in accordance with the size of the joint width D, the joint width D can be maintained while ensuring waterproofness.
It is possible to easily cope with the size of.

The packing member 5 is made of an elastic material such as rubber, and has a hollow core 13 which is stretchable and retractable.
First and second protruding from both side surfaces on the tip side of
A pair of left and right fin pieces 11 elastically contacting each inner surface of the concave grooves 3 and 4
And a closing part 12 projecting from the base end side of the core part 13 and closing the joint part 7 are integrally formed, and each length M of the pair of left and right fin pieces 11 is set to the fin piece 1 in the core part 13.
It is preferable that the length be smaller than the inner dimension N between the fin 1 and the closing portion 12. In this case, when the fin pieces 11 are pinched with fingers and the core portion 13 is sandwiched from both sides, the stretchable hollow core portion 13 is formed. The core 13 and both fin pieces 11 are thinned as a whole, and the core 13 and both fin pieces 11 are easily inserted into the joint portion 7, and the tips of the fin pieces 11 do not reach the closing part 12. Therefore, when the packing material 5 is inserted into the joint portion 7, the thickness of the closing portion 12 can be prevented from being increased by the fin pieces 11, and the closing portion 12 can also be easily inserted into the joint portion 7. Further, both fin pieces 11 are opened inside the grooves 3 and 4 to open the grooves 3 and 4.
By elastically contacting the inner surface of the inside and the closing part 12 closing the joint part 7, the joint part 7 is reliably closed by the closing part 12 and the inclination of the pair of left and right fin pieces 11 can be prevented at the same time.

In a), a first concave groove 3 is formed. A second groove 4 is formed at the other end 2b of the panel unit 2 (here, the end 1b of the panel unit 1 located at the leftmost position) at a position facing the first groove 3. . When the ends 2a and 2b of the panel units 2 adjacent to each other in the lateral direction A are abutted against each other, the first groove 3 and the second groove 4 are arranged to face each other. A packing material 5 or 5 'described later is interposed between the first and second concave grooves 3 and 4. That is, in this example, the panel units 1 and 1 constituting the panel unit 2 are joined together by the same concave and convex fitting as in the past, but the panel units 2 and 2 are joined by concave and concave joining.

The part 7 is closed. In this manner, the fin pieces 11 bite into the interior packing 15, thereby forming the closing portion 12.
Is held in a state of being pressed in the direction of closing the joint 7, whereby the joint 7 is reliably closed by the closing part 12, and water can be prevented from entering from the joint 7. At the same time, the pair of left and right fin pieces 11 are held without being tilted, and the watertightness of the joint portion 7 can be secured. Even if water invades from the closing portion 12, the water is prevented from flowing into the indoor side F by the pair of left and right fin pieces 11, so that the watertightness can be further secured.

Further, since the joint portion 7 can be closed by the closing portion 12, it is not necessary to use a caulking agent as in the prior art, and the labor required for the caulking process can be saved.
As a result, construction can be performed in a short time without being affected by the weather,
It can be performed easily and at low cost, and the finish and waterproofness are improved.
