Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to architectural panels (hereinafter simply referred to as panels) used for external walls, partitions, roofs, etc. of buildings and structures.

[Conventional technology]

Conventionally, the joints of this ring panel were
A structure in which the male and female connecting parts are actually connected as described in the publication, and a bolt is passed through the surface of the connecting part and fixed to the base via a nut, or ■ Utility Model Publication No. 64-449
As shown in the No. 06 publication, a cover plate having an inverted T-shaped cross section was interposed on the back side of a male/female connecting structure.

[Problem to be solved by the invention]

However, since the head of the fixing device is exposed to the exterior, the method (2) has disadvantages in that it is inferior in waterproofness, anticorrosion properties, and design of the exterior. There was also a problem with fire resistance. Furthermore, in order to solve this weak point in fire resistance, it has been considered to interpose a cover plate on the back side to prevent the infiltration of flames and hot air, as described in (2) above, but it is difficult to install a cover plate. This is a time-consuming process, and errors in the installation of cover plates due to layout have a negative impact on the overall appearance of the wall.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention forms a panel by integrally forming a core material made of synthetic resin foam between a metal surface material and a metal back material, so that the width direction of the metal back material is A panel is provided with a reinforcing piece that projects outwardly at one end edge.

[Example] An example of the panel according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a partially cutaway perspective view showing the above-mentioned panel, and the cross section is hat-shaped.
and a core material 7 having a hat-shaped cross section formed on the elongated metal surface material (hereinafter simply referred to as the surface material) and on the back surface of the surface material, and at least the back surface of the core material 7 in the longitudinal direction. Covered metal backing material! (hereinafter simply referred to as the back material) into a sand inch structure. To explain further, the top surface material and the back surface material are mainly metal materials, such as A j25
One type of FeSCu, stainless steel, aluminum/zinc alloy plated steel sheet, colored steel sheet, clad steel sheet, damping steel sheet (sand inch steel sheet), fluorine coated steel sheet, etc. is formed by roll forming, press working, extrusion molding, etc. be. That is, on the surface material, as shown in Fig. 2, there is a long decorative surface 2 and both edges of the decorative surface 2 are bent downward, perpendicular to the decorative surface 2, or inclined inwardly or outwardly. A side wall 3, a protruding piece 4 whose lower end of the side wall 3 is bent outward and extended, and a joint cover fixture guide part 5 whose tip is bent upwardly or downwardly (hereinafter simply referred to as the guide part).
and a side piece 6 which is formed by bending the end edge of the guide part 5 vertically downward. The guide portion 5, as shown in FIG. 4, serves as a guide when installing a joint cover fixture C as shown in FIG. 5, which has a stabilizing piece C+ in the center. In addition, when filling the side piece 6 with the raw material for the core material 7,
This is to prevent the core material 7 from leaking to the guide portion 5 and the surface side of the protruding piece 4, and to make the side edges of the panels A straight so that the panels A are brought into contact with each other without any gaps. Furthermore, the guide portion 5 and the side piece 6 also function as reinforcement for the panel A itself. Also, the length on the surface material is 40
Approximately 00 to 10,000mm, width W+ (width of decorative surface 2) is 4
00~900m, total width Ws is 450~1200nn
At position a, the width W from the edge of the side wall 3 to the side piece 6 is 20 to 1
The height H from the decorative surface 2 to the protruding piece 4 is approximately 10 to 1100 degrees.

The core material 7 mainly functions as a heat insulating material, a waterproof material, a sound absorbing material, a buffering material, or a fireproofing material. The materials include polyisocyanurate foam, polyurethane foam, phenol foam, polyurea foam, one of these with flame retardants and flame retardant additives added, or a laminate of one or more of these, or mineral fiber. , which has a laminated structure with one or more layers of inorganic molded bodies interposed therebetween. Note that the core material 7 is made by discharging a raw material onto the back surface of the surface material and integrating it with a mold structure, or by integrating the molded body with an adhesive.

The main backing material is as shown in FIG. 3, and mainly covers the backside of the core material 7 and has the functions of reinforcing material, waterproofing material, moisture proofing material, fireproofing material, and mold release material. It serves as an isolating material that prevents direct contact with the building frame α.

In addition, as for the main shape of the backing material, one edge in the width direction is
a reinforcing piece 9 protruding outward from the side piece 6 on the surface material;
A protrusion 10 that projects upward from the tip of the reinforcing piece 9 and the reinforcing piece 9
A side piece 11 is formed with the end bent upward, and a notch 12 bent in substantially the same shape as the reinforcing piece 9 is formed on the other end, and a side piece 13 is formed with the tip of the notch 12 bent upward. This is what I did. To explain in more detail, the notch 12 is for storing the reinforcing piece 9 and preventing steps and gaps from forming between the panels A when the panels A are connected as shown in FIG. At the same time, the joints E between the panels A and the joints of the panels A on the back side are shifted, and the reinforcing pieces 9 function as floorboards, thereby greatly improving fireproofing and waterproofing properties. In addition, when the width between the side pieces 11 and 13 of the back material is W4, the length of the reinforcing piece 9 is Ws, and the width of the notch 12 is We, WgξW4, WsξW
・This is the relationship. As shown in FIG. 1, it is preferable that the backing material 1 be formed so as not to come into contact with the top surface material and to prevent the backing material 1 from forming a thermal bridge on the top surface material.

Next, a construction example will be explained.

In order to construct the exterior wall as shown in Fig. 4, we need panel A as shown in Fig. 1, joint material B made of acrylic caulking material, and joint cover fixture made of stainless steel as shown in Fig. 5. C1 It is assumed that a joint portion E is formed using a long joint cover D as shown in FIG. First, a reinforcing piece 9 of a panel A as shown in FIG. 1 is fixed to a frame α made of -2C type steel using fixing devices β made of screws.

Thereafter, the notch 12 of the panel A2 is placed on the reinforcing piece 9 of the panel AI, and the protruding piece 4 is fixed with a fixing device β such as a screw. By repeating this step in sequence, after the joint E of the panel A is formed, the joint material B is then continuously planted across the joint. After that, the fixing part C of the joint cover fixture C as shown in FIG.
A plurality of pieces 8 are fixed using fixing tools β. When all the installation of the joint cover fixture C is completed, the retaining part D+ of the long joint cover D as shown in Fig. 6 is fitted into the locking part C3 of this joint cover fixture C, and the panel is fixed. Joint part E between A
The construction is completed by covering with joint cover D.
