BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of an outer wall prefabricated panel forming an outer wall of a building.

[0002]

2. Description of the Related Art FIG. 4 is a sectional view showing a joint structure of a conventional outer wall prefabricated panel. In the drawing, reference numeral 1 denotes a rectangular panel mounting frame fixed to a building frame (not shown in the drawing) at predetermined intervals, and reference numeral 2 denotes, for example, a hollow rectangular frame material forming a part of the panel mounting frame 1. It is. The panel mounting frame 1 is composed of vertical and horizontal frame members 2. Reference numeral 3 denotes a surface material which is attached to the panel mounting frame 1 by an appropriate fixing means and forms an outer wall prefabricated panel together with the panel mounting frame 1, which is made of a metal such as iron or aluminum, and whose surface is coated with a fluorine resin or the like. May be applied as appropriate. The surface material 3 has a bent end, and is integrally formed with a joint plate portion 3a having a substantially L-shape as a whole.
When the prefabricated outer wall panel is mounted on a building frame (not shown), the joint plates 3a of the surface members 3 attached to the panel mounting frame 1 adjacent to each other overlap each other to shield the frame members 2 from each other.

In the joint structure of the conventional outer wall prefabricated panel as described above, the front end is bent at the surface material 3 and the joint plate portion 3a substantially L-shaped as a whole is integrally formed. At the time of transportation, construction, etc., care must be taken in handling, the bending process is complicated, the production cost of the surface material 3 is increased, and the joint plate portions 3a, 3a to be combined are left and right or up and down. Since the outer wall prefabricated panel composed of the panel mounting frame 1 and the surface material 3 is not symmetrical, it is difficult to position the jointed panel 3a when the prefabricated panel is formed into a complicated shape, which causes a problem in workability. It is limited to square shapes that are simple shapes,
There was a problem that there was no versatility.

The present invention has been made to solve such a problem, and has good workability, sufficiently performs a joint function for preventing rainwater from entering, and can be applied to an outer wall prefabricated panel of various shapes. An object of the present invention is to provide an outer wall prefabricated panel joint structure which is applicable and has high versatility.

[0007]

According to the present invention, a flange bent at a right angle from the peripheral edge of the surface material is attached to a panel mounting frame attached to the building frame via a space adjusting member having an L-shaped cross section. When the panel mounting frame is mounted, the primary seal members provided on the outer surfaces of the opposed flanges of the adjacent surface materials are elastically deformed and adhere to each other, thereby sealing the flange joints, and forming the adjacent panel mounting frame. Since the secondary seal members provided on the side surfaces of the opposing frame members are elastically deformed and adhere to each other to seal the frame material joints, the panel seal frame is slightly attached to the building frame. Even if there is a positioning error, the primary and secondary seal members are elastically deformed to absorb some positioning errors. The delicate positioning of the frame for panel mounting, which was required for the superposition of the joint plate parts of the surface materials, is no longer necessary, and the workability is improved, and the joint seal is provided by the primary and secondary seal members.
