DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like plastering finishing material related to plastering work such as walls, floors and ceilings of a building, a method of manufacturing the same, and a method of performing on-site construction.

[0002]

2. Description of the Related Art Plastering is generally performed as one of the interior and exterior finishing methods for buildings. In ordinary plastering work, a binder such as plaster or mortar, an appropriate fine aggregate and an admixture are prepared on site, and the finishing material is troweled on the ground surface. There is also a method of spraying a finishing material onto the base surface.

[0003]

In ordinary plastering work such as troweling and spraying, it is possible to obtain a finished surface that is seamless and flexible in shape. However, there has been a problem that cracks occur on the finished surface due to drying shrinkage of the material, and in some cases, the finished material peels off and falls off from the base surface. The quality of plastering work depends on the empirical skills of the craftsmen who work on site, and good work cannot be performed unless skilled craftsmen are secured.

The present invention has been made in consideration of the above-mentioned conventional problems, and has as its object to provide a uniform and high-quality work that is easy on-site and that does not crack or peel without relying on the skill of a skilled worker. The goal is to enable plastering.

[0005]

SUMMARY OF THE INVENTION A sheet-like plaster finish material according to the present invention is formed in a sheet shape from a plaster-finish material obtained by adding a suitable fine aggregate and an admixture to a binder such as plaster or mortar. A main sheet, and a base sheet integrally joined to the back surface of the main sheet. The base sheet is made of a napping cloth having a napping face on one side of a base cloth, and a face opposite to the napping face of the napping cloth. Are bonded to the main sheet.

[0006] The sheet-like plastering finish material is a base sheet made of a nap cloth having one side of a base cloth as a nap surface, and an appropriate thin material such as plaster or mortar is formed on a surface opposite to the nap surface of the nap cloth. It can be manufactured by applying a plaster finishing material to which an aggregate and an admixture are added in the form of a sheet, and curing this to form a main sheet.

To perform a finishing work using the sheet plastering material, a binder such as mortar is applied to a concrete surface to be subjected to the finishing work, and the base of the sheet plastering material is applied to the applied surface. What is necessary is just to apply and glue the napped surface of a sheet.

[0008]

The main sheet and the base sheet are not peeled off because the base sheet portion of the raised fabric as the base sheet and the constituent material of the main sheet are joined together in a state where they are entangled well. . When the sheet-like plastering material is adhered to the concrete surface via mortar or the like, the raised surface of the base sheet bites into the mortar and exerts an anchor effect, so that the sheet-like plastering material does not peel from the base. . In addition, the raised fabric as the base sheet plays the role of the reinforcing fiber of the main sheet,
Since the entire sheet-like plastering finishing material has an appropriate flexibility, no cracking of the sheet (cracking of the finished surface) occurs and the adaptation to the ground surface is very good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the appearance and schematic configuration of a sheet plastering finish according to an embodiment of the present invention. As shown in detail in FIG. 2, the nap cloth 1 serving as a base sheet has a plurality of nap threads 1b of an appropriate length projecting from one side of a base cloth 1a made of a woven or non-woven fabric in an almost upright state. The portion where the nap yarns 1b are densely arranged is the nap surface of the base sheet. For example, the base fabric 1a is made of polyester fiber, and the nap 1b is made of polypropylene fiber. In addition, the napped fabric 1 can be knitted with fibers such as vinylon, acrylic, nylon, aramid, and glass, or a composite material containing these fibers.

Then, a material for plastering, which is obtained by adding a suitable fine aggregate and an admixture to a binder such as plaster or mortar, is applied to the surface of the above-mentioned raised fabric 1 opposite to the raised surface in the form of a sheet. Then, an appropriate pattern or the like is formed on the surface thereof, and this is cured to form the main sheet 2. Here, since the plastering finishing material permeates into the base fabric 1a of the napped fabric 1, the base fabric 1a and the constituent material of the main sheet 2 are joined together in a well-entangled state. And the base sheet 1 do not peel off.

The sheet plastering material 10 according to the present invention is produced as described above, and various kinds of sheet plastering materials 10 having different colors, patterns, and constituent materials are mass-produced in a factory in advance. .

In order to perform the finishing work using the sheet-like plastering finishing material 10, as shown in FIG. 3, a binder such as mortar 30 is applied to the surface of the concrete 20 to be finished, and the mortar is applied. Plastering finish 10 on the surface
The above-mentioned base sheet raised surface may be applied and adhered. Then, the raised thread 1b densely arranged on the back of the base sheet penetrates into the mortar 30 and exerts a large anchoring effect, so that the sheet-like plastering finishing material 10 hardly peels off from the foundation concrete 20.

[0013]

According to the present invention, the base sheet portion of the raised fabric, which is the base sheet, and the constituent material of the main sheet are joined together in a well-entangled state, so that the main sheet and the base sheet are joined together. The sheet does not come off. When the sheet-like plastering material is adhered to the concrete surface via mortar or the like, the raised surface of the base sheet bites into the mortar and exerts an anchor effect, so that the sheet-like plastering material does not peel from the base. . In addition, the raised fabric as the base sheet plays the role of the reinforcing fiber of the main sheet, and the entire sheet-like plastering finish material has an appropriate flexibility. The familiarity to the ground is also very good.
Furthermore, this sheet-like plastering finish material can be efficiently mass-produced at the factory, and the use of this material makes the on-site finishing work very easy, and it does not cause cracking or peeling without relying on skilled skills. There is no uniform and high quality plastering finish.
