Description

[Detailed Description of the Invention] The present invention relates to a decorative panel for construction in which a large number of tile pieces are adhered to a molded plate made by extruding asbestos cement material or the like using an extrusion molding machine.

Recently, architectural components made of asbestos-cement materials, etc. are manufactured by extrusion molding using an extrusion molding machine. This has the advantage that products with various cross-sectional shapes can be manufactured.

The present invention relates to the construction of a decorative architectural panel in which tile pieces are attached to at least one side of an extruded board manufactured by the above method, and in particular, it is based on a combination of shapes of recesses and grooves on the surface of the extruded board. This is an extrusion-molded board made by extruding asbestos cement material, etc., and was proposed for the purpose of making it a strong support substrate for attaching tile pieces to the surface and attaching and fixing a large number of tile pieces to the surface. A plurality of recesses of a predetermined shape are arranged parallel to each other at predetermined intervals along the longitudinal direction of the extrusion molded plate, and these recesses are continuous by a combination of dovetail grooves and comb grooves. This is a decorative panel for construction, which forms a surface shape and is configured such that the surface concave grooves firmly support the tile piece with an adhesive such as mortar or synthetic resin for adhering the tile.

The present invention will be specifically explained below with reference to embodiments shown in FIGS. 1 to 4.

In these figures, 1 is an extruded plate made by extruding asbestos cement material etc. with an extrusion molding machine, and one side of the plate has multiple stripes parallel to each other at predetermined intervals along its longitudinal direction. Concave grooves 2 of a predetermined width are disposed on one side of the extruded plate over the entire length in the longitudinal direction, and these vertical concave grooves 2 on one side form a continuous combination of dovetail grooves 2a and comb grooves 2b. The extrusion molded plate 1 has a concave groove formed by a continuous combination of the dovetail groove and the comb groove, which is formed by attaching the tile piece 3 to the adhesive layer 4 using adhesive mortar or synthetic resin adhesive. Attach it to one side of the
The one-sided vertical concave groove 2 is formed by a continuous combination of dovetail grooves a and comb grooves 2b, and is used to fix the tile piece 3 to the one side of the extrusion molded plate 1 via mortar or adhesive. .

Conventionally, when constructing a tile wall by attaching tile pieces to the inner and outer walls of a building structure, work such as adding comb marks to the surface to which the base is attached was performed to ensure good adhesion of the tile pieces. However, the monotonous comb structure alone could not be expected to be completely effective in preventing peeling of the adhesive layer due to contraction and expansion. The present invention is an improvement on the above-mentioned conventional example, and has a configuration in which the dovetail grooves 2a and comb grooves 2b of the concave grooves 2 formed on one side of the extrusion molded plate 1 are used to apply an adhesive. In addition to securing the attachment surface of the tile piece 3, the trapezoidal expansion of the dovetail grooves 2a serves as a strong support for the substrate of the extrusion molded plate 1, and the comb grooves 2b ensure the balance of the entire attachment surface. This is intended to have a synergistic effect with the adhesion effect. The effect is that even when the adhesive layer of the substrate of the tile piece 3 is affected by contraction and expansion, phenomena such as delamination between the adhesive layers can be prevented by the structure of the surface concave grooves 2 as described above. Because of this effect, there is no need to worry about the tile pieces 3 falling off.

Since the present invention has the above-mentioned structural functions, it solves the conventional problems and allows the work of attaching tile pieces to be easily and reliably done without requiring special skills or skill. Moreover, since complicated ground preparation work is not required, it has the practical effect of reducing construction costs.
