DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a spraying material may be used for a wall of a building generally used at present, and is mainly composed of a synthetic resin and an aggregate. As the synthetic resin, an acrylic resin aqueous emulsion is generally suitable, but is not limited thereto. For example, flexibility, weather resistance, adhesion, alkali resistance, water absorption resistance, etc. Any material can be used as long as it has appropriate properties according to the purpose. Examples of such synthetic resins include, for example, vinyl acetate resins, vinyl chloride resins, urethane resins, and the like. These synthetic resins are preferably used as emulsions, particularly aqueous emulsions.
Organic solvent solutions can also be used. Usually, these synthetic resin emulsions or solutions having a synthetic resin solid content concentration of about 40 to 60% by weight are used.

As the aggregate, natural stones, pulverized artificial ceramics, sand and the like are used, and the average size thereof is usually preferably about 0.01 to 2.0 mm. This aggregate may be used in various colors as required. By combining these various color tones and spraying them from each nozzle, it is possible to express colors that are not found in natural products from those that are close to natural stones after spraying.

The mixing ratio of the synthetic resin component and the aggregate can vary depending on the physical properties, appearance, etc. of the target product, and cannot be unconditionally limited. It is preferable to appropriately select and use from a range of about 2 to 3 (solid content weight). In addition,
If necessary, other additives may be further added to the spray material.

As the substrate to which the spraying material is sprayed, an appropriate material may be selected as necessary, and cloth, synthetic resin sheet or film, plate-like material such as wood, metal, gypsum, etc. Or a combination of these is common.

In particular, it has flexibility that can be applied to curved surfaces,
When a sheet having excellent reinforcement properties is used, it is preferable to use a cloth as a base material, and a synthetic fiber woven fabric such as polyester or acrylic, and particularly preferably a cold gauze woven fabric is suitable.

In the case where such a cloth or other flexible base material is used, for example, when a plurality of wire or chain conveyors are used as a conveyor for moving the base material, the flatness of the base material is used. When it is difficult to secure the rigidity, a method in which the base material is placed on a rigid plate-like support and supplied onto a conveyor, and the support is collected after spraying and drying is preferably used. In addition, when using a relatively coarse-grained cold gauze fabric as the base material, the sprayed material sprayed on the base material such as the cold gauze fabric passes through the eyes of the cold gauze fabric and adheres to the support or the like. It is also preferable to provide a releasable sheet, for example, a polyester film or the like, under the base material so as not to be stuck.

Further, in order to improve the adhesiveness with the spraying material, if necessary, the spraying material may be sprayed on the base material and dried in advance, or may be subjected to any other appropriate adhesiveness improving treatment. preferable.

The architectural surface finishing sheet of the present invention can be appropriately used not only on the inner and outer wall surfaces of a building, but also on the surfaces of columns and ceilings. Hereinafter, the present invention will be described more specifically with reference to the drawings.

As shown in FIGS. 1 to 3, spray nozzles 2, 3, 4, and 5 are provided above the base material 1. In the case of this example, the blowing nozzle 2 is a nozzle for lower blowing provided on the upstream side. In this example, one nozzle is provided, but two or more nozzles may be provided.

The spray nozzles 3, 4, and 5 are arranged downstream, and are nozzles for spraying a spray material for forming an upper layer of the building surface finishing sheet, that is, a surface layer. In this example, three nozzles are provided, but two nozzles may be provided, or four or more nozzles may be provided.

These nozzles are connected to the respective pumps 8 via the respective spray material supply pipes 6, and further connected to the supply hoppers 11, 12, 13, 14 for the respective spray materials.

The supply hopper 11 stores a blowing material for downward blowing, and the supply hoppers 12, 13 and 14 store a blowing material for the upper layer. In this example, the hopper 12 has a light color (here, white). The hopper 13 stores a dark (here, black) blast material, and the hopper 14 stores an intermediate color (here, a light red coral) blast material.

Each of the spraying materials supplied to each of the nozzles 2, 3, 4, and 5 from the air compressor 10 via each of the air regulators 9 for adjusting the air pressure and each of the pipes 7 is supplied to each of the nozzles 2, 3, 4, and 5. Compressed air for injection is supplied.

FIG. 5 schematically shows a cross section of the nozzle.
50 is an outer wall of the nozzle, 51 is an internal nozzle for blowing out compressed air, and the internal nozzle 51 is connected to the pipe 7. Reference numeral 52 denotes a spray material supplied from the pipe 6. The structure of the nozzle is not limited to this example only, and any other structure may be used as long as the spray material can be sprayed toward the base material 1.

Each of the nozzles 3, 4, 5 is attached to a support rod 18 as shown in FIG. 3, and the nozzle 2 is attached to one end of a support rod 19. The other end of the support bar 19 is connected to the support bar 18.

The mounting angles of the nozzles 3, 4, and 5 are such that the intersection (that is, the focal point) of the virtual extension line of the central axis of each of the nozzles 3, 4, and 5 is about 10 to 20 cm above the substrate surface. It is preferable to adjust to. The same applies to the case where the number of downstream nozzles is two or four or more.
The nozzle 2 on the upstream side is mounted substantially perpendicular to the base material.

An intermediate portion of the support rod 19 is fixed to a vertical support rod 20, and an upper end of the vertical support rod 20 is
It is connected to. The moving member 21 is attached to the lateral moving support member 22 by an appropriate mechanism, and is capable of reciprocating in a direction transverse to a substrate moving direction described later.

The moving member 21 may be of any mechanism and structure as long as it can reciprocate, and is not particularly limited. For example, as shown in FIG. 4, a gear 53 is driven by a motor 53, whereby a chain 56 hung between the gear and the other gear 55 is rotating in the direction of the arrow. When the moving member 21 moves to the right by the internal mechanism of the chain 21, it moves to the right by engaging with the upper chain of the chain 56, and when the moving member 21 reaches the right end, the moving member 21 moves to the lower chain of the chain 56. An example is a reciprocator having a mechanism in which the moving member 21 moves leftward by meshing. Of course, any other reciprocating mechanism may be used as appropriate, such as using a piston type reciprocator.

Next, the substrate 1 is placed on a chain-shaped endless conveyor 15 installed in parallel with three rows rotated in the direction of the arrow by a motor or the like, and moves from the upstream side to the downstream side. As the conveyor, a wire may be used instead of a chain, or a normal belt-shaped belt conveyor may be used.

The lower side of the conveyor 15 on the side of the chain on which the base material 1 is loaded, that is, the lower side of the chain traveling in the same direction as the movement direction of the base material 1 and the spray material spray nozzle A collection container 17 for collecting the sprayed material sprayed to a position protruding from the base material 1 is provided at a position corresponding to a position below 2, 3, 4, 5 and, if necessary,
The collected spray material collected in the collection container 17 is used for popper 1
It is particularly preferable to supply the ink to the nozzle 1 and spray it from the nozzle 2 as a spraying material for the downward blowing and reuse it from the viewpoint of reducing the loss of the spraying material. Although not shown, a pump may be used to automatically supply and reuse the collected spray material stored in the collection container 17 when supplying the spray material to the popper 11.

As described above, while moving the base material 1 from the upstream to the downstream, and while making the spray nozzle reciprocate in the direction crossing the moving direction of the base material 1, the spray material is jetted from each nozzle. By spraying on the base material, first, a spray material for downward blowing sprayed from the nozzle 1 onto the base material 1 is sprayed, and then the nozzles 3, 4, and 5 on the upstream side emit light color from the nozzle 3. A spraying material (here, white), a spraying material of dark color (here, black) from the nozzle 4, and a spraying material of an intermediate color (here, light red coral color) from the nozzle 5 are spraying materials for the upper layer, respectively. A sprayed granite-patterned heavy building surface finishing sheet is obtained. Usually, this sheet is dried to produce a product. If necessary, after drying, the surface may be sanded using, for example, a wide belt sander or a disc sander.

Incidentally, if necessary, a transparent synthetic resin called clear finish may be further sprayed or applied to adjust the gloss of the surface appropriately. Preferred examples of the clear paint used for the clear finish include, for example, acrylic urethane, acrylic silicone, and fluororesin.

Further, as shown in FIG. 6, a support rod 62 and a plate-like material are placed on a support member 63 provided at a position downstream of the moving direction of the base material 1 after the spraying is completed. By placing the spatula 60 consisting of 61 and by its own weight, it comes into contact with the upper surface of the building surface finishing sheet before drying,
A process for smoothing the surface may be performed. Instead of the spatula 60, for example, a roller-shaped surface smoothing member may be used.

In this way, for example, as shown in FIG. 7, for the surface finishing of a building in which the blowing material 71 composed of the lower blowing material 73 and the surface blowing material 74 is formed on the base material 70 made of cold gauze. A sheet is obtained.

In the above embodiment, the embodiment in which the upstream nozzle 2 and the downstream nozzles 3, 4, and 5 reciprocate synchronously has been described, but the upstream nozzle and the downstream nozzle Of course, each of them may reciprocate separately.
