The present invention relates to a method for manufacturing a building concrete product and a concrete concrete secondary product to which the exterior material such as tiles or stones are attached in advance.

The construction of attaching tiles or stones to the surface to decorate the exterior of the building as decorative exterior materials or the use of tiles or stones as decorative exterior materials for civil concrete products such as parks and roads is increasing every year. .

In addition, products in which tiles, stones, and the like are molded together with concrete are increasing year by year.

In the recent construction industry, in the case of building construction, a factory produces a product in which exterior materials such as tiles or stones are pre-attached to concrete PC boards or partition walls as exterior building materials for buildings as described above, and is fastened to steel frames. How to do is generalized.

In addition, in park construction, general housing, etc., the construction which emphasizes aesthetics is performed by attaching pink corrode stone or non-slip tile.

In the civil engineering industry, L-shaped concrete blocks are used for the construction of land and road construction. However, because the surface is concrete, there are aesthetic problems. To make the L-shaped blocks clean and gangue products, The stacking method is generally performed.

Conventionally, in the factory, the exterior material is attached to these concrete products by attaching the surface of the exterior material such as tiles on the double-sided adhesive sheet and inserting the polyethylene sponge filling material between the exterior material and the exterior material to make a tile sheet pack. It was common to spread the fire by spreading it on a concrete mold using an adhesive sheet and to pour concrete, or in the case of stone, or to put concrete after a worker manually filled a putty material or sealant between stones.

However, in the tile sheet pack as described above, the filling material of polyethylene sponge is poor in adhesion to the exterior material, and a gap occurs between the exterior material and the interior material due to the length error of the exterior material. It cannot be completely prevented from penetrating into the surface of the surface. Therefore, the surface of the exterior material should be washed with water after the completion of the concrete product. Therefore, the manufacturing process, which requires a lot of working time, is unreasonable. It was very difficult to produce uniform products or concrete products with complex stone arrangements.

In recent years, the surface of the exterior material is not smooth, but rubble tiles may be used in the manufacture of concrete products. In this case, it is necessary to prevent the liquid from entering the surface of the exterior material. The manufacture of the concrete product by the conventional method was difficult.

In particular, concrete products using rubble on surfaces (such as building PC boards and partition walls, L-shaped blocks and sidewalk blocks for civil engineering) were very difficult to manufacture.

As mentioned above, it was difficult to manufacture concrete products other than the product of a limited shape or a limited surface by the conventional manufacturing method.

When manufacturing a concrete product other than a limited shape or a limited surface product, there is no manufacturing method other than a method in which a worker directly fills the space between the exterior material and the exterior material with a putty or molds with plaster or foam.

However, such a manufacturing method is inefficient and the manufacturing cost is high and is not generally used.

The present invention is intended to solve the above problems.

In other words, no matter what shape or surface surface material is used, it has succeeded in developing a process that can easily perform a complete sealing for all types of exterior materials at low cost, and thus, it is difficult to manufacture concrete products that have been difficult with conventional methods. It is an object of the present invention to provide a manufacturing method that enables it.

In order to solve the problems as described above, the first invention is a liquid state from the solid state at the melting temperature of 45 ℃ to 80 ℃ by the change of heat inside the mold in which the exterior material is arranged so that the surface of the exterior material faces the bottom of the mold A substance (hereinafter called "filling material") that changes its phase from a liquid state to a solid state at a temperature below the furnace or melting temperature is injected into the molten state between the packaging material and the packaging material. In this case, the concrete is poured, and after the concrete is completely hardened, a method of manufacturing a composite product in which the concrete and the exterior material such as tiles or stones are unified is adopted.

In the present invention, a liquid paraffin, which is an example of a substance whose phase is changed from a solid state to a liquid state or a liquid state to a solid state at a temperature below the melting temperature at a melting temperature of 45 ° C. to 80 ° C. as a filling material. Because of using, any shape or size of the exterior material can not only completely seal between the exterior material and the exterior material, but also can freely adjust the sealing depth.

In addition, the poured concrete is gradually hardened, and since the paste of the concrete cannot flow to the mold surface, even if the surface of any exterior rubble does not cause a problem that the concrete leaks to the surface of the exterior material.

After the concrete is hardened, curing the concrete product with curing air causes the paraffin to melt and become liquid.

When the molten paraffin is discharged from the mold, only the concrete product remains in the mold, and the mold is peeled off.

If some paraffin is attached to the uncast concrete product, clean it with curing air or hot water.

By the above process, a composite product in which exterior materials such as concrete and tiles or stones are manufactured is manufactured.

The second invention, as in the first invention, uses paraffin, which is an example of a material whose phase changes from solid state to liquid state or from liquid state to solid state by the change of heat as a filling material, but in a molten state It is not a method of injecting paraffin into the mold. After putting an appropriate amount of solid paraffin together with the exterior material inside the mold, heat the mold or paraffin to make the liquid paraffin, and the paraffin is solidified and integrated with the exterior material. After the concrete is poured in, and then, a method for producing by performing the curing and demolding process in the same manner as in the first invention is adopted.

In the manufacture of concrete products, there have been examples of using paraffin in the past, but the purpose in that case was used as a release agent, which is completely different from the purpose of use in the present invention.

To the mold for concrete PC, the mold for bulkhead plate, the mold for concrete L type soil block, the mold for concrete flat plate, the mold for concrete sidewalk block, the mold for concrete fence, the exterior materials are arranged and attached in the indicated shape, and paraffin in the molten state Injecting so that the lower part of the packaging material is completely submerged in the liquid paraffin.

In this way, even if there are irregularities of any shape on the surface of the packaging material or the sizes are different, all liquid paraffin is injected into the space between the packaging material and the packaging material, and the packaging material is installed in the liquid paraffin. .

Paraffin naturally solidifies over time.

In the case of rapid solidification, it is cooled by water or cold air or forcedly solidified in a cooling chamber or the like.

In this way, a solid state object in which the lower part of the exterior member and the paraffin are integrated is made.

It is poured by pouring mortar or concrete for coloring fill.

Mortar or concrete is injected on top of the paraffin-integrated cladding, and penetration into the cladding surface can be completely prevented.

The poured concrete solidifies over time in a state below the melting temperature of paraffin, and then supplies air for curing concrete.

When the curing temperature of the concrete is higher than the melting temperature of the paraffin, the paraffin melts and becomes a liquid state.

The liquid paraffin takes out the plug of the hole (paraffin discharge hole) formed in the bottom of the mold and discharges it out of the mold.

Only the composite product in which the exterior material and the concrete are integrated is left in the mold, and by fostering this at a predetermined temperature for a predetermined time, a concrete composite product having increased strength is obtained.

The concrete composite product inside the mold is beautifully finished on the surface of the exterior material, and the shape of the product is a standardized uniform product like the shape of the mold.

Thereafter, the mold is peeled off and the product is taken out, thereby completing a concrete composite product in which the exterior material is attached to the surface in advance.

Also, the paraffin is solidified in the mold without discharging the paraffin, and the mold is removed in the state in which the product and the solidified paraffin are integrated, and then the paraffin is melted with curing air or hot water to separate the concrete product and the paraffin. In some cases.

Paraffin melted by curing air or hot water after being removed from the mold or using the mold can be recovered by reusing only paraffin from water by using the difference in specific gravity between water and paraffin.

EXAMPLE

Next, an embodiment of the present invention will be described with reference to the accompanying drawings of FIGS. 1 to 5.

1 is a partial cross-sectional view of the L-shaped concrete block before the concrete is placed, and arranged on the bottom surface 12 of the L-shaped mold 11 in a designated shape position with the surface of the rubble cladding material 13 facing downward. do.

At this time, when the position fixation of the exterior member is unstable, the exterior member may be placed on the inside of the mold by placing powder such as sand. Next, the paraffin 14 in the molten state is injected so that the lower part of the exterior member 13 is safely submerged in the paraffin 14 in the molten state.

The paraffin in the molten state is injected so as to submerge all the uneven surface of the surface of the rubble cladding material 13, and it solidifies naturally over time, thereby fixing the cladding material 13 to a predetermined shape.

As shown in FIG. 2, after pouring the concrete 15, the finishing surface 16 is completed using a finishing trowel.

The poured concrete 15 is gradually hardened, but since the paste of the concrete 15 does not flow into the bottom surface of the mold 11 completely sealed with the paraffin 14, the surface of the rubble and the concrete (the exterior material 13) ( 15) are not contacted.

After the concrete 15 solidifies, the curing air is supplied and cured, and when the curing temperature exceeds the melting temperature of the paraffin 14, the paraffin 14 starts to melt and liquidizes.

Thereafter, the plug of the hole (not shown in the figure) provided in the bottom of the mold 11 is pulled out and the paraffin 14 is discharged out of the mold 11, and as shown in FIG. 3, the mold 11 Only the composite product in which the exterior material 13 and the concrete 15 are integrated remains.

After raising the strength of concrete by training at a predetermined temperature for a predetermined time and taking out the product from the mold 11, as shown in FIG. 4 or 5, the finished product of the concrete composite product to which the exterior material 13 is attached is obtained. do.

As described above, according to the present invention, by producing a concrete product using the characteristics of paraffin, that is, solidifying on cooling and liquid upon heating, it is attached later by bonding or pressing using a bond or mortar after the concrete is poured. It was possible to manufacture products that could only be manufactured by the method of attaching the exterior materials placed in the mold in advance.In addition, L-shaped concrete blocks or DC bulkheads using uneven rubble can be manufactured. Not only can you produce brilliant products at low cost, but you can also eliminate the cleaning process of your products, avoiding the rationalization of the manufacturing process and reducing the cost, and also by attaching them later by bonding or pressing. Product that completely solved the defect that the exterior material falls from the concrete produced in the manufactured product It can be provided.

In the stone factory, there is a problem in the disposal of industrial waste by disposing of the rubble left after processing the product from the raw stone as it is, but most of the rubble can be used for the production of concrete blocks. As L type block, fence block, door pillar, and other building fence used for civil engineering, it is important to make a single block of concrete product by stacking stones by hand. Construction can be performed using steam, and thus, many advantages, such as reduction of construction cost, construction time, and protection of workers from occupational diseases by work, can be obtained as compared with conventional construction methods.

In addition, since paraffin can be easily molded, it does not require a lot of man-hours, and the recovered paraffin can be recovered by reusing only paraffin from water by using the difference in specific gravity between water and paraffin, and washing the finished product. It is also almost unnecessary, which can reduce the cost.
