Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement in a structure in which building panels adjacent on the left and right are connected via waterproof packing.

[Background Art] Traditionally, adjacent building panels on the left and right have been connected using joiners, and a waterproof seal has been inserted between the building panels to seal them. When finished in this way, there is no problem when it is first finished, but as the waterproof packing changes over time, it may expand and contract, becoming shorter or longer (due to molding distortion, processing distortion, etc.), and there is a risk of water leakage. There was a fear that the appearance would deteriorate.

[Purpose of the invention] The present invention was made in view of the above points, and the purpose of the invention is to prevent the waterproof gasket from expanding or contracting due to the waterproof gasket being locked in the mounting groove of the jointer, resulting in poor sealing. To provide an architectural panel connection structure that does not fade or deteriorate its appearance.

[Disclosure of the invention] The building panel connection structure of the present invention connects the left and right adjacent building panels 1 by interposing the joiner 2 vertically between the end faces of the left and right adjacent building panels 1, and connects the left and right adjacent building panels 1. Mounting groove 3 extending vertically
At the same time, the base of the waterproof gasket 4, which has a substantially identical cross-sectional shape, is fitted, and the seal portion 5 of the waterproof gasket 4 is brought into elastic contact with the end surface of the building panel 1, and protrudes along the longitudinal direction on the inner surface of the mounting groove 3. The provided protrusions 13 are fitted into grooves 15 recessed along the longitudinal direction of both sides of the base of the waterproof packing 4 to prevent the waterproof packing 4 and the joiner 2 from moving in the vertical direction. is locked in the mounting groove 3 of the joiner 2, and the drawbacks of the conventional example are solved by configuring it as described above. In other words, by locking the waterproof gasket 4 in the mounting groove 3 of the jointer 2 so that it does not move in the vertical direction, the waterproof gasket 4 does not expand or contract in the longitudinal direction, resulting in poor sealing or poor appearance. In addition, the mounting groove 3
A protrusion 13 protruding along the longitudinal direction of the inner surface of the
Even if the waterproof packing 4 is installed by sliding it in the vertical direction by fitting into the grooves 15 recessed along the longitudinal direction of both sides of the base of the waterproof packing 4, the waterproof packing 4 can be attached to the board of the building panel 1. It can be installed so that it does not come off in the thickness direction, it can be installed so that the waterproof gasket 4 does not expand or contract in the vertical direction, and it can be installed so that it does not come off in the thickness direction, and it is possible to perform stable sealing. It has become possible to do this.

The present invention will be explained in detail below with reference to Examples.

The wall base 6 is formed by pasting a wall base plate 8 on a rim 7, and a waterproof sheet 9 is stretched over the entire indoor side surface of the wall base plate 8 of the wall base 6. architectural panel 1
For example, it is formed by enclosing a heat insulating material such as foamed polyurethane in a synthetic resin surface plate. A locking groove 10 is provided in the left and right ends of the building panel 1, and a storage recess 11 is provided in the rear side of the end. The joiner 2, which is made of metal such as aluminum, is comprised of a vertically elongated main body 2a and a hat-shaped cross section, and a mounting piece 2b, and a locking piece 12 is provided on the side of the main body 2a. Main body 2a
Projections 13 are provided along the longitudinal direction on both sides of the inner mounting groove 3. Waterproof packing 4 is EVA
It is made of soft synthetic resin and has an approximately pentagonal cross section. In the case of this embodiment, a pair of drain grooves 14 are provided on the left and right of the position that will be on the front side when installed, and a single drain groove 14 is provided on the position that will be on the back side, and the drain groove 14 on the front side is further provided on the surface. Seal portions 5 are provided on both sides. Further, grooves 15 are provided on both sides of the waterproof packing 4 in the longitudinal direction.
is provided, and the base of the waterproof gasket 4 is fitted into the mounting groove 3 of the joiner 2. In other words, by sliding the jointer 2 from the longitudinal end face, the base of the waterproof packing 4 is fitted into the mounting groove 3, and the protrusion 13 is fitted into the grooved line 15, so that the waterproof packing 4 is moved in the longitudinal direction. However, it is designed so that it does not come out toward the surface side. In order to prevent the waterproof gasket 4 from moving in the longitudinal direction, it is caulked from the side of the main body 2a of the joiner 2.
The caulked portion 16 is wedged into the waterproof gasket 4. It is preferable to caulk at three points as shown in FIG. 5. That is, two caulking portions 16 are caulked from one side of the main body 2a, and one caulking portion 16 is caulked from the other side. The three-point caulking locations are two locations indicated by point A near the end, as shown in FIG. Specifically, the total length B of the joiner 2 is 2400 mm, the C dimension is 300 mm, and the D dimension is 150 mm, and each point A is caulked at three points. When we tested the heat resistance temperature of 80 degrees Celsius for the caulked and non-caulked items in this positional relationship, the shrinkage of the waterproof packing 4 was 2% for the non-caulked item, but it was 0.5% for the caulked item. In this embodiment, the caulked portion 16 is formed and secured by caulking, but it may be secured by inserting a nail or pin. However, architectural panel 1
A plurality of panels are arranged side by side in the left and right direction on the waterproof seal 9, and the building panels 1 adjacent to each other on the left and right are shown in FIGS.
They are connected by joiner 2 as shown in the figure. In other words, the mounting piece 2b of the jointer 2 is attached to the wall base material 8 with a nail or the like.
The locking piece 12 of the joiner 2 is locked in the locking groove 10 of the building panel 1. Then, the end face of the building panel 1 is brought into elastic contact with the seal portion 5 of the joiner 2. A drain plate 17 having a substantially L-shaped cross section is arranged at the bottom of the building panel 1, and a vertical piece 17a of the drain plate 17 is attached to a concrete wall 18. The building panels 1 are stretched as described above, and the spaces between the building panels 1 adjacent to each other on the left and right are sealed with the seal portions 5 of the waterproof packing 4. In addition, in this state, even if water enters from the seal part 5 of the waterproof gasket 4, the drain groove 1
4, the water is drained downward and does not accumulate. Therefore, water does not enter the wall base 6 etc. by capillary action and corrode the wall base 6. The water drained downward along the drain groove 14 falls onto the drain plate 17 and is drained.

[Effects of the invention] As described above, in this invention, the waterproof gasket is locked in the mounting groove of the jointer so that it does not move in the vertical direction of the jointer, so the waterproof gasket does not expand or contract in the vertical direction of the jointer. This prevents water from entering due to poor sealing or deteriorating the appearance.Furthermore, the base of the waterproof gasket has a cross-sectional shape that is almost the same as the jointer's mounting groove, and the inside of the mounting groove does not fit inside the mounting groove. The protrusion extending along the longitudinal direction of the side surface is fitted into the concave strip recessed along the longitudinal direction of the base of the waterproof packing, so even if the waterproof packing is installed by sliding it in the vertical direction. The waterproof packing can be installed so that it does not come off in the thickness direction of the building panel, and as mentioned above, it can be installed so that the waterproof packing does not expand or contract in the vertical direction, and it also does not come off in the thickness direction of the building panel. It can be attached as shown in the figure, and the waterproof gasket provides a stable seal.
