Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to residential wall materials as exterior and interior materials, or exterior wall materials for low-rise buildings, as well as for renovation of existing buildings and waste formwork. This invention relates to a formwork for producing decorative panels for pouring.

[Prior Art] Conventionally, in manufacturing decorative panels for construction of this type, as shown in FIG. 5, joint members 12 made of rubber or the like are connected in a lattice shape on a flat plate 11 made of iron plate. A decorative material 8' such as tile or stone is laid between the joint members 12, and a hydraulic material 9' such as concrete or mortar is laid from above.
After the decorative member 8′ and the hydraulic material 9′ are cured integrally, the flat plate 11 and the joint member 1
2, a decorative panel for construction is produced which is made up of a decorative member 8' and a hydraulic material 9', and in which joints are formed between the decorative members 8', 8', . . . .

[Problems to be Solved by the Invention] By the way, the external dimensions of the decorative member 8' cannot be made with perfect precision, and it is normal that there is a certain degree of dimensional error (for example, about 2 to 3 mm). Therefore, when manufacturing the conventional architectural decorative panel described above, even if the joint member 12 is made of a rubber material or the like and has minute elasticity, the above-mentioned dimensional error of the decorative member 8' is caused by the joint member 12. When a large number of decorative members 8' are laid, some of the decorative members 8' may rise or a gap may be created between the decorative member 8' and the joint member 12, causing the hydraulic substance 9' to be absorbed. Inconveniences such as intrusion occurred. Also,
For the same reason, the joint member 12 is the decorative member 8'.
They were firmly wedged in between, and it required a great deal of effort to separate the completed architectural decorative panel from the flat plate 11 and the joint member 12.

Furthermore, when connecting a large number of architectural decorative panels in a planar manner, no improvements have been made to the joining surfaces in the case of architectural decorative panels manufactured from conventional architectural decorative panel production forms. Therefore, not only accurate and smooth construction work could not be carried out, but also disadvantages remained, such as rainwater entering through the joints.

The present invention was made to solve the problems of conventional architectural decorative panels as described above.
It is possible to absorb the dimensional errors of the decorative members and easily place the decorative members in a predetermined position, and it is also possible to easily remove the mold from architectural decorative panels. To provide a formwork for manufacturing decorative panels for construction, which can provide a decorative panel for construction that is easy to construct and can completely prevent rainwater from entering through joints when connecting panels in a planar manner. The purpose is to

[Means for Solving the Problems] The problem in manufacturing the conventional architectural decorative panel described above is that it has a flat bottom portion on which a decorative member is laid and a surrounding frame connected to the bottom portion, and the upper surface of the bottom portion A convex part for joints is continuously recessed along the outer shape of the decorative member up to the surrounding frame, and a cut groove is provided below the convex part for joints. The joint convex portion is made of a flexible material, and a surrounding frame stepped portion is recessed in the inner corner of the upper surface of one side of the surrounding frame, and the surrounding frame on the other side opposite to the surrounding frame on one side is recessed. The present invention is solved by a formwork for manufacturing decorative panels for construction, characterized in that a peripheral frame convex portion having a cross-sectional shape substantially the same as the cross-sectional shape of the peripheral frame stepped portion is recessed in the inner corner portion of the upper surface. It is something.

[Examples] Hereinafter, the contents of the present invention will be explained in detail based on Examples.

FIG. 1 is a plan view showing an embodiment of a mold for manufacturing decorative architectural panels according to the present invention, and FIG. 2 is a sectional view taken along the line AA in FIG. 1. In FIGS. 1 and 2, the formwork 1 for manufacturing architectural decorative panels is made of a slightly flexible material, such as a rubber material or a soft resin material such as urethane, and has good shape retention and flexibility. It has a certain degree of surface elasticity, and the bottom part 2 on the flat plate and the surrounding frame 3 are integrally connected, and the top surface of the bottom part 2 has a convex part 4 for joints and a decorative member 8 made of tile, stone, etc. A cut groove is formed continuously along the outer shape of the joint up to the peripheral frame 3, and a cut groove is formed below the joint convex portion 4.

In FIG. 1, the convex parts 4 for joints are recessed in a grid pattern, but this is because the decorative member 8 is rectangular in this case, and the outer shape of the decorative member is circular, triangular, triangular, etc.
...If the joint convex portion 4 has another irregular shape, the arrangement shape of the joint convex portion 4 will change accordingly.

When using the formwork 1 for manufacturing decorative architectural panels, as shown in FIG. The required number of decorative members 8 are laid on the upper surface of the bottom 2 with the convex parts 4 for joints interposed therebetween, and reinforcing members 10 made of metal steel, iron bars, etc. are arranged as needed, and from above the decorative members 8 are laid. The hydraulic substance 9 is poured into the decorative member 8 and the hydraulic substance 9 is cured integrally with the decorative member 8.
The panel is removed from the mold, and a decorative panel for construction is completed with decorative members arranged on the surface and joints arranged between the decorative members.

The above-mentioned formwork 1 for manufacturing decorative architectural panels is easy to mass-produce in a factory, etc., and can also be used at construction sites when constructing walls.
By disposing the formwork 1 for manufacturing decorative architectural panels of the present invention on the surface of the wall body, pouring a hydraulic material from the inside and curing and curing, removing the formwork for manufacturing decorative panels for buildings. This is done effectively and beautifies the wall surface.

Further, as shown in FIGS. 1 and 2, the formwork 1 for manufacturing decorative architectural panels includes a peripheral frame 3 on one side.
A peripheral frame stepped portion 3a is recessed in the inner corner of the upper surface, and a peripheral frame having a cross-sectional shape substantially the same as the cross-sectional shape of the peripheral frame stepped portion 3a is provided in the inner corner of the upper surface of the opposite side of the surrounding frame 3. The convex portion 3b is recessed, and as a result, as shown in FIG. , a convex portion 6a and a step portion 6b corresponding to the peripheral frame stepped portion 3a and the peripheral frame convex portion 3b are formed, and when connecting a large number of architectural decorative panels 6, 6... in a planar manner, it is easy to construct and rainwater is removed.
