DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for constructing a decorative panel that is a cement/concrete panel that is pre-manufactured in a factory and has excellent workability on site.

[Prior Art] A conventional method of constructing a decorative panel is to attach the decorative panel to a building structure or a support column fixed to the building structure with screws from the surface. Additionally, the adjacent top, bottom, left and right joints of decorative panels were repaired by filling them with mortar.

[Problems to be Solved by the Invention] As mentioned above, when installing decorative panels using the conventional construction method, holes are opened from the finished panel surface on one surface and fixed with screws. Even if repairs are made by filling in mortar or the like that is approximately the same color as the panel, the surface of the repaired area often discolors or becomes uneven over time, impairing the aesthetic appearance of the decorative panel.

Also, the top and bottom and left and right joints between decorative panels.

Although repairs are made with mortar, etc., cracks often form due to changes over time and the effects of heat.These cracks can cause the mortar to peel off and rainwater to infiltrate through the cracks. This will cause damage to decorative panels and structures.

Furthermore, when fixing decorative panels, a large number of man-hours are spent on fixing screws, repairing screw fixing holes, and repairing panel joints.

Therefore, the present invention makes it extremely easy to join panels to each other on-site, does not cause structural or waterproof defects in the joint, and furthermore, when fixing to a structure, it is possible to screw the panel from the finished surface. To provide a decorative panel construction method that does not rely on methods that impair aesthetic appearance as much as possible.

[Means for Solving the Problem] The problem described above is to fix a plurality of support columns vertically to a building structure at regular intervals, and to horizontally fix the rail members to the plurality of support columns while moving them up and down. A plurality of decorative panels are arranged at regular intervals between the vertically opposing rail members, and are made of cement, concrete, etc. and have rail groove members embedded in the horizontal direction of the upper and lower end surfaces of the panel. This problem is solved by a method for constructing a decorative panel, which is characterized by engaging a groove member, slidingly moving it, and fixing it at a desired position.

[Example] Hereinafter, an example of the method for constructing a decorative panel according to the present invention will be described based on the drawings.

A plurality of tiles 2 are aligned so as to have the desired panel dimensions while being engaged with each other, and a panel made of cement/concrete material is joined to the back side of the two layers of cut-back tiles.

In addition, in the cement/concrete panel 3, a substantially U-shaped rail groove member 4 made of strong metal is provided on the upper and lower end surfaces of the cut-back tiles 2 on the joint surface side.
are buried with the same dimensions as the length of the panel 3 in the longitudinal direction, with the openings facing the upper and lower end faces of the panel 3.

First, on the structure side to which the decorative panel 1 is fixed, a metal C having a substantially C-shaped cross section is attached to the surface of the structural plywood 7.
A plurality of support columns 6 made of shaped steel are fixed at regular intervals in the vertical direction. Next, on the front side of the support columns 6, a plurality of metal H-shaped bars 5 having a substantially H-shaped cross section are horizontally installed. It is fixedly installed on the support pillar 6 of. In this way, the H-shaped rule 5 is routed around the structure except for corners and openings such as windows.
The shapes do not necessarily have to be closely connected to each other, and as shown in FIG. 3, an appropriate gap may be provided within a range that does not affect the bonding of the decorative panel 1.

Next, another H-shaped rule 5 is fixed above and below the H-shaped rule 5, and the distance between the upper and lower sides is the same as the vertical dimension of the decorative panel 1. As a result, between the upper and lower H-shaped bars 5,
The upper and lower rail groove members 4 of the decorative panel 1 are engaged with the H-shaped rails 5.

The decorative panel 1 can be freely moved in the left and right directions.

After fixing the H-shaped rule 5 to the entire surface of the structure, first attach the corner-shaped decorative panel 10 to the lowermost position of the structure using screws at the corner to the support column 6, as shown in FIG. Screw it in from both sides, and repair the screw hole by filling it with mortar of the same color as the surrounding area.

Next, the flat decorative panel 1 is engaged with the upper and lower H-shaped rules 5 and slid, and the corner-shaped decorative panel 1 to be joined is
Arrange them near 0. Then, a caulking material such as silicone is applied evenly to the surface of the convex stepped portion in the left-right direction of the corner-shaped decorative panel 10 that engages with the concave stepped portion in the left-right direction of the adjacent decorative panel 1 so as not to leave any gaps. Then, either the left or right edge of the adjacent decorative panels 1 is engaged with and fixed to the edge of the corner-shaped decorative panel 10.

In this way, decorative panels 1 are fixed one after another starting from one of the corners of the structure by sliding them on the H-shaped rule 5, so that the bottom row of the structure is fixed. When the installation is completed, the decorative panels 1 and 10 are then fixed to this upper row in the same manner as described above, and each time the installation is completed in that row, the panels are moved to the upper row. , decorative panel 1,
