Description

  The present invention relates to an attachment structure for laminated composite materials, and more particularly to an attachment structure capable of efficiently joining laminated composite materials used as an inner wall panel or a ceiling panel of a building without impairing the aesthetic appearance of the panel.

  Metal resin composite plates formed by sandwiching and adhering resin sheets from the front and back sides with metal plates are widely used as outer walls of buildings, wall panels of interior materials, and ceiling panels. This metal resin composite plate is a polyolefin resin in which a resin sheet (thickness of about 3 to 6 mm) serving as a core material is filled with a non-flammable inorganic filler, and metal plates on both sides (thickness of about 0.3 to 0.5 mm). Is made of aluminum, stainless steel, titanium, or the like, is lightweight and highly rigid, and has excellent workability and design. In particular, when titanium or stainless steel is used as the metal plate, excellent corrosion resistance is also exhibited. In addition, patent document 1 can be mentioned regarding the improvement technique of metal resin composite board itself.

When such a metal resin composite plate (hereinafter referred to as a laminated composite material) is actually used as a wall surface panel or a ceiling panel, it is necessary to hold and fix the panel portion to the wall surface or ceiling portion of the building. . Conventionally, various connection methods have been proposed as means for holding and fixing a panel portion made of a laminated composite material, and a typical method is shown in FIG.
In FIG. 9, reference numeral 20 denotes a Z-shaped panel holding base material to be attached to a building wall surface of a building, and 21 denotes a laminated composite wall surface panel or ceiling panel held and fixed to the base material 20. (A) is an example in which the panel 21 is fixed to the base material 20 with bolts and nuts 22, (b) is an example in which the panel 21 is fixed to the base material 20 with screws 23, and (c) is a panel 21 to the base material 20. (D) shows an example in which the metal plate on the back surface side of the panel 21 is fixed to the base material 20 with rivets 25, respectively. As a prior art of the wall panel mounting structure, Patent Document 2 for the purpose of reinforcing effect and cost reduction by reinforcing ribs can be cited.

However, in the conventional typical connection method, in the example of fixing with the bolt 22 in FIG. 9A, the screw 23 in FIG. 9B and the joiner 24 in FIG. There is a problem in terms of the appearance of the panel because the tool appears through the panel, and the method using the rivet 25 in (d) has a problem in connection strength, although the appearance is not impaired. .
An object of the present invention is to solve the problems of the conventional connection means described above, and since no metal fittings for connection appear on the surface side of the laminated composite material, the surface aesthetics are maintained and sufficient connection is achieved. It is an object of the present invention to provide an attachment structure that can secure strength and can hold a stable composite material.

The laminated composite mounting structure according to the present invention for solving the above-described problems is obtained by attaching a laminated composite material formed by fixing metal sheets to the front and back surfaces of a resin sheet to a building surface of a building via a base material. In a laminated composite mounting structure that constitutes a wall or ceiling panel of a building, an oval plate having a bolt in the center is arranged between a pair of opposing arcuate plates on a circular base plate. A joining metal fitting is inserted into an opening corresponding to the diameter of the base plate provided on the back side metal sheet of the composite material, and a pair of arcuate plates are extended beyond the outer periphery of the base plate by the rotation of the oval plate. The laminated composite material is held by a joining metal fitting by being polymerized on the side metal sheet.
In the above, the pair of arcuate plates on the base plate is provided so as to project the pivot point on the base plate provided at the opposite ends to the shaft, or provided symmetrically with the center on the base plate. The protrusions are superposed on the laminated composite by projecting the arcuate plate by sliding along the long holes formed in the middle of the arcuate plate.
In addition, the resin sheet located in the circular opening of the back side metal sheet of the laminated composite material is cut out concentrically with the opening of the back side metal sheet, and the resin is put in the remaining space where the joint metal fitting is put in this notch. It is preferable to inject and fill the material.

  According to the mounting structure according to the present invention, necessary and sufficient connection strength can be maintained, and since no connection means appears on the surface side of the composite panel, the aesthetic appearance is not impaired, and it is extremely practical. A joining means can be obtained.

Hereinafter, two embodiments of the laminated composite mounting structure according to the present invention will be described with reference to the drawings. In the actual mounting structure, a plurality of identical mounting structures are provided at regular intervals on the back plate of the laminated composite material.
