Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a method for manufacturing architectural decorative panels, and more particularly, to architectural decorative panels that are attached to the outer wall, inner wall, floor, or ceiling of a building. The present invention relates to a decorative panel manufacturing method.

[Prior Art] Among architectural decorative panels that are installed on the outer wall, inner wall, floor, or ceiling of a building, for example,
As shown in FIGS. 4 and 5, a conventional architectural decorative panel G using natural stone as a decorative board includes a plate-shaped base material 10 made of concrete 12 in which reinforcing bars 11 are embedded, and this plate-shaped base material 10. Treated material 20 on the surface of
A plurality of decorative laminates 30 made of natural stone are integrally attached at intervals through
It is composed of 0.

In this way, conventional architectural decorative panels use materials that best match each of the treated material 20 for adhering the decorative laminate 30 to the plate-like base material 10 and the sealing material 40 for preventing joints 30a. It is made of different materials for use. Therefore, when pasting the decorative board 30 with the treated material 20, care is taken to prevent the treated material 20 from protruding from the joints 30a and staining the surface of the decorative board 30.
A back-up material 50 made of rod-shaped foamed polyethylene or the like is always filled, and the outer surface of the back-up material 50 is filled with a sealing material 40.

However, since the rod-shaped backup material 50 is not a fluid material like the processing material 20 or the sealing material 40, a gap is always formed when it is filled. For this reason, moisture such as rainwater may accumulate in the gaps formed by the back-up material 50 during the manufacturing process, and this may later seep into the joints, causing stains as shown by symbol M in FIG. 4, or When the decorative board 30 is made of natural stone, there is a problem in that the residual water passes through the decorative board 30 and causes efflorescence (efflorescence phenomenon) as shown by symbol N, which significantly stains the appearance of the panel. It was hot.

[Problem to be solved by the invention]

As mentioned above, the object of the present invention is that the adhesive treatment material and the sealing material of the decorative board are made of different materials,
To provide a method for manufacturing a decorative panel for construction which eliminates staining of the panel due to residual water and has an excellent appearance in manufacturing the decorative panel for construction using back-up material.

[Means to solve the problem]

The present invention achieves the above object by placing a plurality of decorative laminates 30 on a planar surface of a formwork K with their front side facing down and at intervals corresponding to the joint portions 30a. Processing material 2 is placed in the center of 30a.
At the same time, a backup material 50 is buried in the joint 30 to approximately the middle of the depth of the joint 30a so as to be in contact with the formwork K, and an adhesive injection material P is applied to the top of the joint 30a. 30a filled with
and fill it so as to overlap with the treated material 20, and then pour concrete 12 so as to cover the entire surface of the adhesive injection material P and the treated material P,
After the concrete becomes the plate-shaped base material 10 and hardens, the entire decorative board 30 is turned over so as to be peeled off from the formwork K, and then the back-up material 50 in the joints 30a is removed, and the This is characterized by filling the space with a sealant 40.

In this way, when the adhesive treatment material for the decorative board and the waterproof sealant for the joints are made of different materials, it is important to remove the back-up material filled in the joints and replace it with the adhesive injection material. Since the top is filled with sealant, there are no gaps formed at the joints like in conventional panels. In addition, the decorative panels were arranged face down in the formwork, and then the plate-shaped base concrete was poured on top of them and then turned over, resulting in a uniform, flat panel surface, creating an appearance with no irregularities. be able to.

Hereinafter, the present invention will be specifically described with reference to embodiments shown in the drawings.

FIGS. 1 and 2 show an example of an architectural decorative panel manufactured according to the present invention. E
is a decorative panel for construction, which includes a plate-like base material 10, a plurality of decorative laminates 30 integrally attached to the surface of the plate-like base material 10 at intervals through treated materials 20,
A sealing material 40 is filled on the surface side of the joint portion 30a of each decorative board 30.

In the manufacturing method of the present invention, in particular, an elastic injection material P is applied to each joint portion 30a from the plate-like base material 10 side to approximately the middle of the joint depth.
is applied.

Next, the specific structure and manufacturing method of this architectural decorative panel E will be explained with reference to FIGS.

(a) First, a predetermined number of natural stone decorative boards 3 are placed on the formwork K.
0 is placed at a predetermined interval, that is, at an interval corresponding to the joint portion 30a, so that its surface (lower surface in the figure) is in contact with the formwork K. (See Figure 3a) (b) Backup material 5 made of foamed polyethylene is placed in contact with the formwork K in the joint portion 30a.
0 is inserted, and at the same time, the treatment material 20 is applied to the back side (upper surface as viewed) of each natural stone decorative board 30 except for the vicinity of each joint portion 30a. (See FIG. 3b) The treatment material 20 may be applied in advance to the back side of the decorative board 30 except for the vicinity of each joint portion 30a. In addition, this treated material 20
In this example, the back surface treatment material 21 and the silica sand 2
After applying the back surface treatment material 21,
Silica sand 22 is uniformly sprinkled on the surface.

Note that the back surface treatment material 21 is made of epoxy resin, silicone resin, or the like.

(c) Next, from the plate-shaped base material 10 side, the joints are formed near the joints 30a of each decorative board 30, that is, the parts to which the treated material 20 was not applied in the previous process, and inside the joints 30a. The elastic injection material P is applied so as to reach approximately the middle part of the depth. (See FIG. 3c) It is preferable to use elastic epoxy resin, urethane resin, butyl rubber, polysulfide rubber, or the like as the injection material P.

(d) Continuously, concrete 12 is poured so as to cover the treated material 20 and the injection material P, and the wall thickness of the concrete 12 is approximately 1/2 of the predetermined dimension of the plate-shaped base material 10.
When this is reached, reinforcing bars 11 are inserted at appropriate intervals, and concrete 12 is poured until the wall thickness reaches a predetermined dimension of the plate-like base material 10, and the poured concrete 12 is cured in this state until it hardens. (See Figure 3d) (e) After curing, remove from the formwork K and take out the backup material 50 inserted in step b above from inside each joint 30a. (See FIG. 3e) In this step, it is preferable to turn over the decorative board 30 so that each decorative board 30 faces upward, as shown in the figure, for the sake of carrying out the subsequent work.

(f) After that, the present architectural decorative panel E can be obtained by filling the sealing material 40 into the space left after the backup material 50 was taken out in the previous step. (See Figure 3 f) [Effects of the Invention] As described above, in the present invention, when manufacturing a decorative panel from different materials, the adhesive treatment material for the decorative board and the waterproof sealing material for the joints are different. The back-up material filled in the joints was removed and replaced with an adhesive injection material, and a sealant was then filled on top of it, so gaps caused by the back-up material were formed at the joints, like in conventional panels. There's nothing to do. Therefore, stains such as efflorescence caused by water remaining in the gaps will not occur.

In addition, in the method for manufacturing decorative panels for construction according to the present invention, the decorative boards are arranged in the formwork with their front sides facing down, and the plate-shaped base concrete is poured over them and turned over, so that the panel surface It becomes a uniform flat surface that follows the surface of the planar formwork, creating a beautiful appearance with no unevenness.
