BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to architectural panels (hereinafter simply referred to as panels) useful for constructing the outer and inner walls of buildings and structures. More specifically, even if the decorative surface width and panel thickness are increased, the male and female mating structure will not peel off from the wall base, and fixing tools such as nails will not be exposed to the outside. This relates to panels that can be stretched horizontally.

0002

2. Description of the Related Art Conventionally, as shown in FIG.
A method has been devised in which the panels are connected by a male-female fitting structure, and the end of the panel a1 is fixed to the wall base α using a fixture β.

0003

[Problem to be Solved by the Invention] However, a gap γ is formed between the panels a1 and a2 by the head of the fixing tool β, and rainwater etc. blown up from the joint part b can be absorbed by the wall foundation due to this large gap γ. There was a drawback that it was transmitted to the α side and corroded the wall base α. In addition, since the fixture β is formed near the joint part b, rainwater etc. can directly reach the head of the fixture β,
Since the fixture β reaches the fixing hole drilled in the panel a1, there are drawbacks such as rusting of the fixture β and rainwater entering the wall base α from the fixing hole. Furthermore, joint part b
The fixing tool β was visible from the outside through the gap, and the aesthetic appearance was greatly degraded. Further, the reinforcing piece c formed interposed in the core material is fixed by the fixture β, but when the panel a1 is fixed by the fixture β, the reinforcing piece c
was deformed, making it extremely difficult to drive the fixture β, which was a major drawback in construction. Furthermore, if the wall thickness of the protruding part d of panel a2 is thin and physical pressure is applied to the joint part b from the outside, the protruding part d will easily deform, which may affect the aesthetics of the joint part b. There is a disadvantage that the strength of the joint part b is inferior, such as impairing waterproofness.Furthermore, in the event of an external fire, the panel a will be deformed and curved due to the heat, and the protruding part d will bend and deform outward as a result, causing the joint part to become damaged. The gap in part b was increased, allowing the flame to reach the back side, resulting in poor fire protection.

0004

[Means for Solving the Problems] In order to eliminate such drawbacks, the present invention fixes the panel at one end, and also fixes it from the surface side of the surface material by connecting the fixing groove of the male connector and the female connector. The upper surface of the mold connection part side covers the fixture, and
Waterproof due to the combination of drop-in structure and real structure.
In addition, we have improved workability by having a structure in which the reinforcing pieces interposed in the core material on the fixed part side are not fixed with fixing tools, and we have also formed reinforcing ribs on the top surface of the surface material to improve the structure of the joints. This provides panels with improved strength and fire resistance.

More specifically, as shown in FIG. 2, the surface material 1 has a gutter-like portion 1a formed from a horizontally long decorative surface portion 2, a male connecting portion 6, and a female connecting portion 12. The surface portion 2 is formed from side walls 3 and 4, in which both ends of the decorative surface 2a in the longitudinal direction are bent inward at an arbitrary angle, and a joint base 5 whose lower end edge of the side wall 3 protrudes outward. The male connecting part 6 has an upper edge 8 that projects further outward from the tip of the joint base 5, and an insertion edge 7 that is made up of a lower edge 9 that bends the tip of the upper edge 8 inward in a substantially U-shape. , a concave fixing groove 10 formed on the upper edge 8 of the insertion edge 7, and a reinforcing piece 11 with the tip of the lower edge 9 bent inward in an L-shape. As shown in FIG. 5, the insertion edge 7 is a part that is inserted into a fitting groove 15 of a female type connecting part 12 to be described later and is fixed to the wall base α, and a fixing tool β such as a nail is inserted into the fixing groove 10. This is the part that functions as a fixing part that is installed and fixes the panel A to the wall base α. Further, the concave fixing groove 10 is formed to be larger than the height and width of the nail head of the fixing tool β, so that the fixing tool β does not protrude above the surface of the joint basement 5, and the panel A is not engaged with the fixing tool β. When doing so, no gap is formed at the contact portion between the upper surface 13, the joint base 5, and the upper edge 8, which will be described later, and the fixing groove 10 forms a gap to prevent capillary phenomenon and strengthen waterproofness. In addition, the length from the tip of the insertion edge 7 to the upper edge 8 side of the fixing groove 10 is l1, and the length from the tip of the insertion edge 7 to the tip of the reinforcing piece 11 is l2.
Then, the relationship l1 > l2 is established so that the reinforcing piece 11 does not get in the way when the fixing tool β is driven into the fixing groove 10. In addition, the reinforcing piece 11 is interposed within the core material 20 to strengthen the integration of the surface material 1 and the core material 20, and when the insertion edge 7 is inserted into the fitting groove 15, the insertion edge 7 is This serves to prevent deformation due to pressure from the lower surface 14 and to ensure secure fixation. Female connection part 1

Assuming the relationship l3 < l4, the upper surface 13 as shown in FIG.
This covers the head of the fixing tool β to improve waterproofness and aesthetics. Further, the fitting groove 15 is connected to the male connecting portion 6.
This is the part that is engaged with the insertion edge 7 of the panel A and fixes the panel A to the wall base α. Note that the steps 2b and 2c formed on the decorative surface 2a
By making the decorative joints step-like, the joints are made three-dimensional and clear, and the design is improved. In addition, the reinforcing ribs 23 reinforce the strength of the side wall 4, and protect the joints from external physical forces.
In the event of a fire from the outside, the side wall 4 is prevented from bending and deforming outward, and flames are prevented from reaching the wall base α, contributing to improved fire protection. In addition, the reinforcing rib 23
The shape is arbitrary, and can be formed into a continuous waveform as shown in FIGS. 6(a) and 6(b), for example.

As shown in FIG. 3, the backing material 17 has an extension portion 18 that is bent inward from one end edge of a long plate into a U-shape approximately parallel to the plate, and the other end is bent in a vertical direction. Furthermore, it is formed from a notch portion 19 that is approximately parallel to the plate material and bent outward, and in the figure, an extension portion 18 and a notch portion 19 are formed.
Stabilizing pieces 18a and 19a are formed by bending the tips of the two pieces upward, and these pieces function as guide surfaces during engagement and as molds during production, and a gutter-like portion 17a is formed from these pieces. This back material 17 covers the back surface of a core material 20 (to be described later) to make the panel A a sandwich structure, and improves the mechanical strength of the panel A itself. It serves as a packing material, etc., and its materials include the same material as the surface material 1, or asbestos paper, kraft paper, asphalt felt, and metal foil (Al, Fe, Pb, Cu).

At the same time, the engagement piece 22 is engaged so as to fall into the engagement groove 21, thereby fixing the panel A to the wall base α. In addition, the extension part 18 and the notch part 19 are intended to significantly improve fireproofness, waterproofness (preventing rainwater from entering the wall base α), and airtightness, especially in the unlikely event of a fire. This is to prevent flame from penetrating to the back surface 17b and to make the panel A able to pass the fire resistance test. In addition, in the figure, surface material 1 is used to further improve fire resistance.
and the back material 17 are formed so as not to contact each other, thereby preventing thermal bridges.

The core material 20 is mainly made of synthetic resin foam, which functions as a heat insulating material, a reinforcing material, a soundproofing material, a cushioning material, a fireproofing material, an adhesive material, etc. For example, polyisocyanurate foam, phenol foam, Synthetic resin foams such as polyurea foam and polyimide foam, and flame retardants (borates, silicates, phosphates, etc.) in these synthetic resin foams.
