[Conventional technology]

Examples of this type of panel that have been conventionally used include (a) Japanese Patent Publication No. 51-29339, (b) Jikkosho Publication.
51-11882, (c) Utility Model Publication No. 54-26649, etc. However, the biggest drawback of this type of panel is that the decorative surface becomes mountain-like, and a wall formed using it has the appearance of a continuous mountain. In other words, when the decorative surface of the panel becomes mountain-like, it not only has a poor aesthetic appearance, but also is difficult to install, lacks waterproofness at the connecting portion, and has disadvantages such as detachment. In addition, many of these types of panels have a hanging structure, which has the disadvantage of uneven joint width due to construction. Furthermore, the decorative surface of this type of panel is flat (including embossing) due to its design, and is merely a step or uneven surface, which has the disadvantage of lacking a three-dimensional effect. In addition, among this type of panels, panels with a drop-in type connection structure are also known, but they have a three-dimensional effect, waterproofness, heat insulation, workability,
The disadvantage was that it lacked economic efficiency.

[Purpose of the invention]

In order to eliminate the above-mentioned drawbacks, the present invention forms the decorative surface part in the shape of a step consisting of a plurality of inclined decorative pieces, and provides the stepped part with a recessed part having a gap to strengthen the stepped part. The dividing line is made clearer, and a decorative groove is provided between the upper end of each inclined decorative piece and the stepped part, and the upper edge of the uppermost inclined decorative piece is recessed along the longitudinal direction of the panel. By providing a joint at the horizontal joint that is formed when the panels are connected, the three-dimensional effect of the step and horizontal joint can be further enhanced, and the appearance of the horizontal joint and the step can be made to closely resemble each other. can be done by one worker without requiring any skill.
Furthermore, the present invention proposes a panel that does not cause deformation of the decorative surface, is waterproof, and has significantly improved three-dimensionality.

This enhances the three-dimensional effect of the stepped portion 3 and improves the strength of the panel together with the stepped portion 3.
Furthermore, even if the thickness of the panel A and the angle of inclination of the inclined pieces 2a and 2b are made smaller, it is possible to increase the size of the stepped piece 4 in the stepped portion 3, which reduces the large shadow caused by the stepped piece 4 and the lower surface 6a of the decorative groove 6. The combination of small shadows greatly enhances the three-dimensional effect of the decorative surface section 2. Also, the bottom surface 7 of the joint part is panel A.
A joint 25 that performs the same function as the decorative groove 6 at the side joint part when connected as shown in
It is intended to form a Therefore, the joint bottom surface 7 has substantially the same shape as the decorative groove 6. Therefore, the stepped portion 3 and the side joint portion have a very similar appearance, and a unified line is created in the wall formed by the panels A, giving it a three-dimensional effect and an aesthetically pleasing appearance. In addition, the male connecting part 8 consists of a groove part 9 which is recessed at the tip of the bottom surface 7 of the joint part parallel to the longitudinal direction to prevent rain and capillarity, and a reinforcing rib 10 (pipe-shaped in the figure) formed at the tip of the groove part 9.

It is formed from a flap-like tongue piece 15 provided on the top. The female connecting part 16 has a stepped piece 17 which is formed by bending the lower end of the decorative surface part 2 inward, the other edges are bent inward to form an upper edge 18, and the tip of the upper edge 18 is bent outward to form a lower edge 19. The fitting groove 20 is formed into a substantially U-shaped cross section.
and a tongue piece 21 which is bent inward at the tip of the lower edge 19, and the lower edge 19 is formed from the insertion edge 11.
It is inserted into the engagement groove 12 when the holder is fitted into the engagement groove 20, and is useful for further strengthening the engagement force and waterproofness. Note that the dimensions and angles of each part of the surface material 1 are set as follows. That is, as shown in FIG. 2b, the heights of the stepped pieces 4 and 17 are h ₁ ,
h ₂ , the height from the vertices 4a, 17a of the step pieces 4, 17 to the base line A when panel A is constructed is h ₃ ,
h ₄ , the angles of the step pieces 4, 17 with respect to the base line A are θ ₁ , θ ₂ , the angles between the decorative pieces 2 a, 2b and the step pieces 4, 17 are θ ₃ , θ ₄ , from the innermost part of the engagement groove 12 Insert edge 11

Further, θ ₁ and θ ₂ are arbitrary angles, for example, 45 to 110 degrees. The above relationship is shown in panel A
This is so that the step part 3 and the horizontal joint part will have almost the same appearance when constructed on the frame α as shown in Figure 3, and the wall formed by panel A will have a uniform horizontal line. This is to improve the appearance, create a three-dimensional effect, and more clearly create a three-dimensional effect. In addition, the gutter-like portion 22 connects the decorative surface portion 2 to the male and female connecting portions 8,
16, and is for filling the heat insulating material 23. Reference numeral 23 is a heat insulating material, which is filled at least in the gutter-like portion 22 to impart heat insulating properties to the panel A, and secondarily has adhesive properties and
It is made of a type of material that has features such as nonflammability. Specifically, it consists of one type of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., which is discharged as a raw material, molded, hardened, self-adhesive, or a molded body. It consists of seeds. In addition, when using a molded body, an adhesive (not shown) is required between the heat insulating material 23, the surface material 1, and the back material 24. To explain further, the heat insulating material 23 is mainly made of synthetic resin foam, such as resin for polyurethane foam, resin for phenol foam, resin for polyisocyanurate foam, and flame retardants and flame retardant aids (borax, methane). It consists of one or more of the following: sodium borate, antimony trioxide, calcium carbonate, aluminum hydroxide), bentonite, pearlite grains, and shirasu balloons. The backing material 24 is at least the heat insulating material 23
The mechanical strength of the panel A itself is strengthened by forming the panel A into a sandwich structure together with the surface material 1 and the heat insulating material 23. Moreover, it functions as a member of a noncombustible sheet, a waterproof membrane, a heat shield sheet, a water absorbing sheet, a soundproof sheet, a release sheet, a packing material, a reinforcing sheet, and the like. The materials include, for example, asbestos paper, kraft paper, asphalt felt, metal foil (Al, Pb, Fe), synthetic resin sheet, rubber sheet,
One type of cloth sheet, glass cloth, or a combination of more than one type of these, or one type of sheet treated with waterproofing, flame retardant, etc., or one type of metal plate as described above. It is what it is.

[Construction example]

The panels A ₁ and A ₂ were formed using a 0.27 mm thick color steel plate as the surface material 1 as shown in FIG. 2a. In addition, aluminum kraft paper is used for the backing material 24, and the heat insulating material 23 is made by discharging the raw material for polyisocyanurate foam between the surface material 1 and the backing material 24, reacting and foaming, and then curing and integrating. This is what I did. Therefore, the extension portion 14 of the n-th panel _A1 is fixed to the frame α consisting of main pillars, studs, etc. via nails β. Next, the n+1st panel A ₂
The fitting groove 20 of the female connecting part 16 is fitted into the insertion edge 11 of the male connecting part 7 of panel _A1 to form a horizontal joint as shown in FIG. In addition, in order to form the entire wall, the steps described above may be performed from the base to the girder. The wall body formed in this manner has excellent waterproof properties at the horizontal joints, and the horizontal joints and the stepped portions 6 have a very similar appearance, resulting in uniform horizontal lines and a high aesthetic appearance.

〔Effect of the invention〕

As described above, according to the construction panel according to the present invention, since at least one stepped portion is formed in the decorative surface portion, the strength is sufficiently reinforced and the decorative surface does not become mountain-like. Since the folded gap formed by the recess and the decorative groove are provided in the stepped portion, the three-dimensional effect is greatly enhanced by the shading created by the step piece and the shadow created by the lower surface of the decorative groove. In order to form a joint that closely resembles a decorative groove at the side joint part, the appearance of the stepped part of the architectural panel and the side joint part are almost the same, creating lines with a rich three-dimensional effect and forming a wall body with excellent aesthetics. is possible. The grooves formed on the insertion edge not only allow rain to escape, but also prevent capillary action and greatly improve waterproofness. Since the male and female joints have the above-mentioned drop-in structure, it can be easily carried out by one person, the joint width (horizontal) can be kept constant, and it is highly waterproof. The construction panels have a sanderch structure, which improves their strength. Insulating material is filled as the core material of the construction panel, and the side joints are filled with insulating material.
Since it is multi-layered, it has excellent insulation properties. Because the surface material is wide, it is easy to install, and the width of the material can be used effectively, making it highly economical. It has the following characteristics and effects.
