Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an apparatus for connecting external wall panels that is attached to the outer surface of a building frame.

<Prior Art> External wall panels have conventionally been attached to the outer surface of a building frame in order to protect the outer surface and provide a decorative effect.

External wall panels can be installed in a series of multiple panels vertically and horizontally, but the joints of each panel are overlapped and sealed with a tight material or sealant to ensure that the panels and the building frame are connected. Prevents rainwater from entering between.

<Problems with conventional technology> However, as the tight material or sealing material deteriorates over time, cracks and gaps may occur, reducing the sealing performance of the joint.
There was a problem that a difference occurred between the internal pressure and the external pressure in the space between the building frame and the panel, and rainwater entered the space.

<Means for solving the problem> In view of the fact that such problems are caused by the use of tight materials and sealing materials, the present invention solves the problem without using such tight materials and sealing materials. This is a uniquely designed structure in which external wall panels are connected in a row to prevent rainwater from entering.

That is, the connecting device according to the present invention is a building exterior wall panel in which a plurality of panels are attached to a building frame at regular intervals from the outside surface of the building frame and are connected in a row while partially overlapping each other. A gap is provided between the side edges of the panels, and a protrusion is partially formed in the overlapped part of one panel to face the overlapped part of the other panel, and the protrusion is brought into contact with the overlapped part of the other panel, so that both A communication gap is formed between the overlapping portions, and the space formed between the panel and the building frame is communicated with the outside air through the gap.

<Examples> The present invention will be described below based on illustrated examples.

As shown in Figures 1 and 2, the exterior wall panels include a top panel P1 attached to the upper end of the building frame 1 and main panels P2 and P3 connected below it. The top panel P1 has a rectangular panel base 2 having a decorative surface A, and a first overlapping portion 3 projecting out from the panel base 2 at a different level. It has only on the side edge, and on the opposite vertical side edge 4 and lower horizontal side edge, there is a second overlapping portion 3 of the adjacent panels P1 and P2.
It has a polymerized portion 4.

Further, the main panel P2 has a first overlapping portion 3 on one vertical side edge and an upper horizontal side edge, and has a second overlapping portion 4 on the opposite vertical side edge and a lower horizontal side edge. .

The first overlapping portion 3 has two grooves 5 and 6 on its outward facing portion, and some portions of the groove 5 located on the outer circumferential side are slightly raised than the surface portion thereof. A first protrusion 7 is provided.

Similarly, the second overlapping portion 4 has two grooves 8 and 9 on the opposite side of the body, and in some places within the groove 8 located on the outer circumferential side, there are second grooves slightly raised from the surface portion. It has a protrusion 10.

Note that the first polymerized portion 3 of the top panel P1 is
An L-shaped corner tight material 11 is attached to the lower corner portion (b) of the main panel P2, and L-shaped corner tight material 12 is attached to the three corner portions (c) of the first overlapping portion 3 of the main panel P2. ing.

When installing the top panel P1 and main panel P2, start with the top panel P1. L-shaped brackets 13 are attached to four locations above and below the surface facing the body of the top panel P1, and these brackets 13 are connected to a frame-side bracket 14. Each of the brackets 13 and 14 is provided with a long hole (not shown) so as to be orthogonal to each other, so that the position can be adjusted in the indoor/outdoor direction and in the left/right direction.

After installing the top panel P1 at the right end in FIG. 2 in this way, the next top panel P1 is installed in the same way, but in this case, the first overlapping portion 3 and the second overlapping portion of the left and right adjacent top panels P1, P1 are attached. 4 are overlapped and a gap 15 is formed between both side edges.

After the installation of the top panel P1 is completed, the main panel P2 located below it is then installed. Two brackets 13a are attached only to the lower part of the main panel P2 on the side facing the main panel P2. The lower bracket 13a is fitted into the space formed therebetween, and the lower bracket 13a is connected to the frame-side bracket 14a, thereby immovably fixing the main panel P2.

In this way, the main panels P2 are installed one after another, but a gap 15 is formed between the bottom edge of the top panel P1 and the side edge of the adjacent main panel P2, and a gap 15 is formed between the bottom edge of the top panel P1 and the side edge of the adjacent main panel The first overlapping portion 3 and the second overlapping portion 4 of the main panel P2 overlap each other.

Since the protrusions 7 and 10 provided respectively are interposed and abutted between the first and second overlapping parts 3 and 4, a gap 16 is formed between both the overlapping parts 3 and 4, and the side It communicates with the gap 15 between the edges and also with the space 17 between each panel P1, P2 and the building frame 1.

Therefore, this space 17 communicates with the outside air and is in a constant pressure state, making it possible to prevent rainwater from entering due to the difference in air pressure. In addition, the grooves 5, 6, 8, and 9 formed on the opposing surfaces of the overlapping portions 3 and 4 mutually form a labyrinth, which has the effect of reliably preventing rainwater from entering through the gap 15. There is.

Moreover, as shown in FIGS. 2 and 5, the panel P
1. In the continuous state of P2, the corner tight materials 12 provided at the corner portions C come into close contact with each other, thereby creating a gap 15 between each side edge.
The interior and exterior communication spaces created at the joints between the first overlapping portions 3 are sealed to prevent rainwater from entering.

In addition, in FIG. 1, 18 indicates the brackets 13, 13.
A is a spacer that is interposed between the panel base 2 and the panel base 2 when attaching the panel a.

In order to close the open space created between the top panel P1 and the building frame 1, a cap (simplified by a dashed line) is attached to the building frame 1 so as to straddle the top panel P1 and the building frame 1, as shown in FIG.

<Effects of the invention> As is clear from the above examples, the present invention forms a communication gap in the overlapped part of the panel by a protrusion provided in the overlapped part of the panel, and connects the panel and the building frame through the gap. Since the space between them communicates with the outside air, the space always maintains an equal pressure relationship with the outside air pressure, and prevents rainwater from entering due to the difference in air pressure.

Therefore, there is no need to use a sealing material such as a tight material or a sealing material over the entire joint, which eliminates the operational complexity and cost increase associated with the use of such a sealing material, and reduces deterioration due to aging. There is no need to worry about this, and the reliable water leakage prevention effect can be maintained for a long period of time.
