Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a fastening structure for a composite building board.

[0002]

[Prior art]

 Hitherto, ceramic-based inorganic building boards containing cement as a main component have been widely used as building boards. By the way, if these ceramic-based inorganic building boards remain as they are, the ground color is an achromatic color of gray-black to gray-black, and the design is poor. Is customary. As a makeup method, there is a case where a thin decorative plate, for example, a thin layer of natural stone or a ceramic plate is laminated and adhered to the surface of a ceramic-based inorganic building plate. The above-mentioned makeup means is widely used because it gives a considerable design property because the entire building board has the appearance and texture as if it were made of the material of these surface layers.

[0003]

[Problems of conventional technology]

 However, since the above decorative layer is simply laminated with an adhesive, for example, when it is used as an outdoor building board such as an exterior wall board, it repeatedly expands and contracts due to the temperature difference due to aging such as solar heat and the cold season. As a result, the adhesive layer is apt to deteriorate and peeling cannot be effectively prevented.

[0004]

[Problems to be solved by the device]

 In view of the above problems, the present invention has been made with the object of perfecting the interlayer adhesive strength when applying surface makeup with a decorative plate, and completely eliminating problems such as peeling even if adhesive deterioration occurs. It is a thing.

[0005]

[Means for Solving the Problems] That is, in the fastening structure for a composite building board of the present invention, a decorative board 3 is laminated on a surface 1A of a ceramic-based inorganic building board 1 via an adhesive 2, A mounting metal fitting 5 in which a claw piece 5A is inserted into a groove 4 formed on the end surfaces 3A and 3B of the decorative plate 3 is fixed to the surface of the ceramic-based inorganic building board 1 via a fastener 6, and further the fixing metal fitting. 5 is embedded by a sealing material 7 filling the space between the decorative plates 3, 3.

[0006]

【Example】

 Next, an embodiment of this invention will be described. 1 is a perspective view of an essential part of an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG.

The fastening structure for a composite building board according to the present invention is a decorative board made of natural stone or ceramic through an adhesive 2 on the surface 1A of a ceramic-based inorganic building board 1 such as a fiber-reinforced cement extruded building material. 3 is laminated, and a mounting bracket 5 in which a claw piece 5A is inserted into a groove 4 formed on the end surfaces 3A and 3B of the decorative plate 3 is fixed to the ceramic inorganic building board surface 1 through a fastener 6. Further, these fixing fittings 5 are embedded by a sealing material 7 filling the space between the decorative plates 3 and 3.

In the above, as the adhesive agent for adhering the decorative plate 3 to the ceramic-type inorganic building board 1, a conventionally known adhesive agent is used, for example, a two-liquid type epoxy adhesive agent or the like is used. Needless to say, other than the above, a synthetic resin plate or the like can be used as the decorative plate. Further, as for the mounting bracket 5, when the decorative plates 3 and 3 are arranged on both sides, the mounting bracket 5 having a hat-shaped cross section is arranged, and when the decorative plate 3 is arranged on one side, As shown, a hook-type metal fitting 5 utilizing the hollow portion 1B of the building board 1 is used.

Further, the fastener 6 is composed of an anchor plug 6A and a screw 6B which is screwed into the anchor plug 6A. The anchor plug 6A is inserted into a hole 6C preliminarily drilled, and the screw 6B is screwed into the anchor plug 6A to anchor the anchor. A plug that expands the plug 6A in the radial direction and fastens it is used.

[0010]

[Action]

 In this invention, since the end face of the decorative plate 3 is fixed to the surface of the ceramic-based inorganic building plate 1 by the other mounting bracket 5 which is adhered by the adhesive 2, the adhesive is temporarily invalid. Also the decorative board is surely supported. Further, since the mounting member 5 and the fastener 6 are hidden by the sealing agent 7 filling the space between the decorative plates, they are not conspicuous.

[0011]

[Effect of device]

 As described above, when the surface is made up with another decorative plate, not only the adhesive but also the mounting bracket is used to fix the surface, so there is no risk of peeling even if the adhesive deteriorates over time. The mounting material is hidden by the sealant, so it is not noticeable in appearance. Further, according to the fastening structure for the composite building board of the present invention, since the decorative boards 3 are fixed by the mounting fittings after the decorative boards 3 are bonded, it is not necessary to wait for the adhesive to harden, and the manufacturing management is easy. It has various practical effects such as
