Abstract

PURPOSE:To provide building panels having uneven surfaces giving fine touches and containing aggregates exposed thereon by transferring a squeezing plate tilted in its proceeding direction at a prescribed height to extend the kneaded product of the fine aggregates with an adhesive, and subsequently drying the extended kneaded product. CONSTITUTION:A pattern frame 3 in which plural rectangular sections 4 are arranged in a zigzag state is put on a substrate 2 as a base, and the kneaded product of fine aggregates with an adhesive is distributed into each section 4 from the side above the pattern frame 3. A squeezing plate 1 is slid along the upper edge of the pattern frame 3 to level the kneaded product so that cavities are not produced over the edges of the sections 4 of the pattern frame 3, thus surely charging the kneaded product in the pattern frame 3. The pattern frame 3 is removed, and the charged kneaded product panels are dried and cured. Since the squeezing plate 1 is transferred in the forward tilted posture, the fine aggregates are not excessively buried, and the panels having finely uneven surfaces on which the fine aggregates are exposed in the state of natural stones cut with a cutting machine are produced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a building panel suitable for finishing an exterior wall or an interior for a remodeling or a new construction.

[0002]

2. Description of the Related Art Since finishing of outer walls in wooden houses, prefabricated houses and other offices, factories, etc. is regarded as important in terms of design, many finishing materials are used. If this outer wall must have excellent weather resistance and durability, and fire protection must be taken into consideration, for example, the building standard law stipulates that the outer wall be finished with lath and mortar. .

A general lath / mortar coating wall is, for example, a lath base plate on a pillar or a stud, and a wire lath is fixed with a staple on the asphalt felt. Finished with gun. This lath and mortar coating finish is simple and inexpensive to construct, and has the advantage of fire protection. Further, there is an advantage that a color mortar can be sprayed to finish the color richly.

However, even if it is legal in the Building Standards Law, this lath and mortar coating finish has a drawback that the shaft materials such as the base and column bases are easily corroded, so it is necessary to devise a method for improving the air permeability inside the wall. Was needed. Also, in the lath mortar plaster wall, when it gets old, some cracks and damages occur,
There is a drawback that rainwater penetrates into the inside through the cracks and the like and corrodes the outer wall itself and the shaft material. In addition, repairing this damaged portion required a lot of work, and it was necessary to remove the lath mortar coating wall once to regenerate it as a new one.

In addition, there is a drawback that the outer wall design is standardized, and in recent years when various designs are adopted for construction, new materials and designs have been desired as wall materials. There is also a method of finishing the outer wall with tiles, but this is done by applying lath mortar on the lath base plate and attaching the tiles one by one, so it is troublesome to attach this tile. In addition, the construction period is long, the cost is high, and rainwater may intrude into the interior unless the joints are properly finished.

[0006] Therefore, it complies with the Building Standards Law, fire resistance,
As a wall material used as an outer wall material or an inner wall material with a new design while having durability, a kneaded product of fine-grain aggregate and adhesive is formed on the surface of the base substrate as the base material. A wall material in which a hardened surface layer material is formed and a plurality of molding sections arranged in a mosaic pattern is integrally formed on at least the surface portion of the surface layer material and a method for producing the wall material have been proposed (Japanese Patent Laid-Open No. 3-232754).

By the way, when spreading and filling the kneaded material of the fine aggregate and the adhesive in the above-mentioned molding section, the kneaded material is placed in the molding section and spread by a spatula-shaped scraper manually by an operator. It was postponed and filled.

[0008]

However, in the case of spreading with a scraper at the time of shifting to mechanization, even if a kneaded product of the same composition is used, if the spreading state is different, the tile-like smoothness is obtained. In some cases, the exposed fine-grained aggregate was dragged in the spreading direction to form a striped pattern.

According to the present invention, a fine aggregate having a fine texture, which is obtained by cutting a natural stone with a cutting machine, has an uneven surface.
An object of the present invention is to obtain a method for manufacturing a building panel in which a kneaded product of fine aggregate and an adhesive is spread on a substrate.

[0010]

In the method for manufacturing a building panel according to the invention described in claim 1, a kneaded product of a fine aggregate and an adhesive is spread on a substrate, and the kneaded product is obtained. In the method for producing a building panel for drying and curing, when spreading the kneaded material, the wiping plate inclined in the traveling direction is moved at a predetermined height on the substrate to spread the kneaded material. .

In the method of manufacturing a building panel according to the second aspect of the present invention, a frame having a predetermined height is placed on the substrate, and a kneaded material of the fine aggregate and the adhesive is placed in the frame. In a method of manufacturing a building panel, which comprises spreading and filling, removing the frame, and then drying and curing the kneaded product, a wiping plate inclined in the traveling direction is slid along the upper edge of the frame. The kneaded product is spread and filled.

Specifically, the inclination angle of the wiping plate is about 30 ° or more and about 60 ° or less with respect to the substrate surface,
Further, the fine aggregate of the kneaded product has a particle diameter of 1.5 mm or less, and the kneaded product has a viscosity of 20,000 to 60,
000 cps, more preferably 30,000 to 4
Disclosed is 10,000 cps.

[0013]

In the present invention according to claim 1, after the kneaded material of the fine aggregate and the adhesive is put on the substrate, the wiping plate (squeegee) inclined in the traveling direction is moved at a predetermined height. Since the kneaded product is spread by doing so, it is possible to obtain a fine uneven surface in which the fine-grained aggregate having the texture of the natural stone as it is cut is exposed.

The angle of the wiping plate with respect to the horizontal plane depends on the type of fine aggregate, the state of particle size distribution, the type of adhesive, the compounding ratio of fine aggregate and adhesive, etc. However, if the angle is too large, the wiping plate will carry away too much material, and the fine aggregate will be dragged to form recesses along the moving direction. Conversely, if the angle is too small, the wiping plate will be wiped off. The plate presses the surface too much, and the exposed fine-grained aggregate is pushed into the inside to make it too smooth, resulting in a tile-like smooth surface.

Further, in the invention according to claim 2, a frame having a predetermined height is placed on the substrate, the kneaded material of the fine aggregate and the adhesive is put into the frame, and the wiping is inclined in the traveling direction. The kneaded product is spread and filled by sliding the take-up plate along the upper edge of the frame, and then the frame is removed, and the kneaded product is dried.
Since it is a material that hardens, spread the kneaded product on the thickness of the frame,
It is possible to fill the inside of the frame, and it is possible to obtain a fine uneven surface in which the fine-grained aggregate having the texture of the natural stone as it is cut is exposed.

Various sizes and materials can be selected for the wiping plate. That is, when sliding along the upper edge of the frame, if the size of the wiping plate is naturally insufficient for the frame, good spreading and filling cannot be performed, It needs to be long enough. The material may be any plate-shaped material that can wipe off the kneaded product, various materials can be used, and when the metal plate is spread as a wiping plate, the surface obtained Becomes smoother, and when a wood or plastic plate is spread as a wiping plate, the obtained surface has a rougher surface than that of the metal plate described above.

Further, the inclination angle of the wiping plate is preferably about 30 ° or more and about 60 ° or less with respect to the substrate surface, more preferably about 45 °. There is no fear that the aggregate will be dragged to form a recess in the sliding direction, or that the fine-grained aggregate exposed by the wiping plate will be pushed into the interior and not over-smoothed.

Further, the composition of the kneaded product is less likely to cause the fine-granular aggregate to be dragged by the wiping plate, and it is difficult for the fine-granular aggregate to be pushed into the inside by the wiping plate.
And the viscosity of the kneaded material is 20,000 to 6
10,000 cps, more preferably 30,000
~ 40,000 cps (B-type viscometer, No4
Rotor, 6 rpm) is recommended.
