PURPOSE:To improve property of execution, moldability, safety, grade of appearance and durability. CONSTITUTION:A backing is formed by a three-dimensional knitting texture which has a thickness of 0.7 to 20mm and which comprises matrix structures 32, 34 on front and back sides, at least one of the matrix structures 32, 34 having mesh-shaped or groove-shaped voids, and connection threads 36 connecting the matrix structures 32, 34 to each other. A material comprising cement or resin or a mixture thereof as a main agent is filled in and covers the backing for molding. A coating material gets into the voids of the three- dimensional knitting texture to exhibit a firm anchoring effect and a bridging effect, thereby preventing peeling, falling and crack of the coating material.

Three-dimensional knitted fabrics 5 and 1 used as the base of the present invention
Nos. 2 and 29 are woven and knitted by a double Russell knitting machine or a moquette loom. More specifically, the front side ground structures 32 and 33 and the back side ground structure 3 shown in FIGS.
4, 35 are connected by connecting yarns 36, 37 to form a three-dimensional fabric, which is used as a base. Figure 5 shows the front and back ground textures 32 and 3
4 shows a honeycomb-type three-dimensional knitted woven fabric configured in a mesh shape, and FIG. 6 shows a reversible type three-dimensional knitted woven fabric in which a front side ground structure 33 is formed in a mesh shape and a back side ground structure 35 is formed in a flat structure. There is.

Front side ground structure 32, 33 and back side ground structure 3
The fiber material used for Nos. 4 and 35 may be any of synthetic fiber, regenerated fiber, natural fiber, inorganic fiber, and the like, and may be a single or mixed yarn. Further, there is no limitation on using these yarns in the same kind or different kinds on the front and back, or knitting or knitting.

Front side ground structure 32, 33 and back side ground structure 3
4 and 35 can adopt any organization, but as a characteristic combination of the organization, the ground organization 31 on the front and back,
34 also has a mesh-like structure, the front side ground structure 33 has a mesh shape and the back side ground structure 35 has a flat structure, and a groove-like void is formed by partially providing a missing portion in the longitudinal direction of the front side ground structures 32, 33. The front side ground textures 32 and 33 and the back side ground textures 34 and 35 are partially provided in the longitudinal direction to form a groove-like void. The
Even if the ground texture of both sides is mesh or flat,
It doesn't matter if the front and back are different. Of course, there is no limitation when the mesh-like and flat ground structures are mixed on one or both of the front and back sides. Front side ground structure 32, 3
Nylon 6 and nylon 6 are used as the materials for the connecting threads 36 and 37 that three-dimensionally connect 3 and the backside fabrics 34 and 35.
6, synthetic fibers such as nylon 46, polyester, polyethylene and polypropylene are preferred. Furthermore, since it requires three-dimensional shape retention, an appropriate amount of voids, and compression elasticity, a yarn having an appropriate rigidity such as mono-multi or mono-filament having a diameter of 0.025 to 0.4 mm is suitable.

The gap between the connecting yarns 36 and 37, the arrangement position, the arrangement direction, etc. are such that the front side ground textures 32 and 33 and the back side ground textures 34,
It is a matter that can be taken into consideration or can be arbitrarily determined as necessary. For example, the ground textures 33 and 35 on the front and back sides may be connected in the vertical direction, or any two members in the sideways direction or the diagonal direction, or even three members may be arranged in combination and connected. Further, the connecting threads 36 and 37 may be arranged in a partially missing (missing tooth) shape. As described above, in order to stably maintain the three-dimensional shape of the woven and knitted three-dimensional knitted fabric and to easily and uniformly apply the resin or fill the resin, heat setting is preferably performed by a tenter. Further, it is possible to stabilize the three-dimensional shape by impregnating and curing the three-dimensional knitted fabric with an appropriate amount of resin.

The three-dimensional knitted fabric has a thickness of 0.7 to 20 mm.
It is necessary to be within the range of the above, and when the material whose main component is cement or resin or a mixture thereof is applied, coated or filled into the three-dimensional knitted fabric, the bridge effect is obtained. Alternatively, the anchor effect is sufficiently exerted, and the effect of preventing peeling, falling off, cracking, etc. of the coating material can be obtained. When the thickness of the three-dimensional knitted fabric is less than 0.7 mm, there is a problem that the anchor effect and the bridge effect for holding the coating material cannot be sufficiently exhibited. When the thickness of the three-dimensional knitted fabric exceeds 20 mm,
The coating material is not sufficiently filled in the voids, resulting in poor three-dimensional shape retention. Therefore, the thickness of the three-dimensional knitted fabric is preferably 2 to
It is judged to be about 15 mm.

When the three-dimensional knitted fabric thus obtained is manufactured, the surface of the basic modeling skeletons 4 and 26 or the pseudo rock panels 14 and 30 are enclosed, and further, the back surface of the steel skeleton structure wall 26 is formed. It will be installed. The coating material used for the molded article is not particularly limited, but examples include cement, sand, natural soil, stone powder (marble, andesite, granite, etc.), glass fiber, glass chips, polyester resin, epoxy resin. , Lipoxy-based resin, urethane-based resin, rubber latex-based resin, etc., alone or in combination of two or more, and pour this material,
Among the conventionally used processing methods such as coating, painting, and spraying, the molding is performed by a preferable method for molding.

Here, reference will be made to a method for producing a pseudo rock panel. First, as shown in FIG. 7, a concave mold 42 is taken from a rocky place of a natural stone 41 using silicon or urethane resin. Next, as shown in FIG. 8, the coating material 4 is formed along the concave mold 42.
3 is sprayed with a spray gun 44 in a thickness of about 10 to 15 mm. Next, the three-dimensional knitted fabric 45 is laid along the shape of the concave mold 42, and at the same time, the mounting bracket 46 is arranged.
A coating material 47 having a thickness of about 10 to 15 mm is sprayed thereon by the spray gun 44 as described above. After that, when the molding material is hardened and removed from the concave mold 42, a pseudo rock panel is created. In this case, the coating material is, for example, a mixture of cement, sand, glass chips and a reinforcing resin (polyester-based, epoxy-based, etc.) and water.

[0016]

As described above, the present invention has a thickness in which at least one of the front side or back side ground textures has a mesh-like or groove-like void, and the front side and back side ground textures are connected by a connecting yarn. The base is formed by a three-dimensional knitted fabric of 0.7 to 20 mm, and the coating material for modeling bites into the voids of the three-dimensional knitted fabric and is stronger than the metal lath, which is the base used in the conventional method. The anchor effect and the bridging effect are exerted, which prevents the coating material from peeling off, falling off, and cracking. Furthermore, since the three-dimensional knitted fabric that is the base is soft and has the flexibility of three-dimensional deformation, it has good workability, is safe and easy to model, has a beautiful finish (looks good), and is extremely resistant to rust. It is possible to manufacture an excellent molding composition.
