Abstract

PURPOSE:To produce an excellent surface decorative concrete block by freely adjusting the amounts of decorative aggregate, sealing aggregate and mortar by providing a tapered projecting surface to the upper part of a box body and further providing many holes to the bottom surface thereof. CONSTITUTION:A retaining mold 1 has a box body 2 at the bottom part thereof and also has a tapered projecting surface at the upper part thereof and drain holes 6 are provided to the bottom part of the box body 1. Decorative aggregate is thrown in the retaining mold 1 and sealing aggregate is subsequently thrown therein to apply vibration to said mold 1. It is sufficient to once apply vibration after the aggregates are thrown in the mold 1. Subsequently, water or water containing a water-soluble adhesive is sprayed. Bonding often becomes inferior when the sealing aggregate is wet to a necessary degree of more. If the drain holes are provided to the bottom part of a face plate, excessive water is discharged from the drain holes. Thereafter, vibration is applied if necessary and the face plate is subsequently coated with mortar if necessary and, after concrete is cast to be compacted under vibration, the molded one is demolded and aged to obtain a surface decorative concrete block. By this method, the amounts of all of the decorative aggregate, the sealing aggregate and mortar, respectively can be freely adjusted and a projecting degree can be sufficiently adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing a surface-decorated concrete block, which is particularly effective also in a pouring method, and a face plate for forming a surface-decorated concrete block.

[Conventional technology]

Conventionally, methods for producing finished concrete products with natural stone exposed on the surface include embedding natural stone in the surface before the concrete hardens, and fixing natural stone etc. with ice on pallets and then pouring concrete, mortar, etc. A concrete product in which concrete is poured over the decorative aggregate, pressurized and vibrated, cured, and then the faults are separated and the laminated state is exposed on the decorative surface. (Japanese Unexamined Patent Publication No. 53-136028), but with any of these methods, the attached natural stone tends to peel off easily, or when using larger aggregates such as natural stone as a surface decoration material, it is difficult to make the surface decoration. The drawback is that the concrete does not bond well and the natural stone tends to peel off, making it impossible to manufacture concrete products with a finish that exposes the natural stone on the surface.

In addition, all conventional methods are relatively small.

It can only be used for decorative aggregates with a certain shape, and cannot be used for large decorative aggregates or decorative aggregates of various sizes. It was only very limited.

Furthermore, in the conventional method, the bare surface of the concrete is inevitably exposed at the joints, giving the product an artificial atmosphere.

Therefore, the present applicant and his colleagues previously filed an application for a method for manufacturing concrete products whose surface is decorated by exposing the aggregate (Japanese Patent Application Nos. 60-142,813 and 1982-142,814).

In addition, the method applied by the present applicants made it possible to manufacture finished concrete products with surface decoration exposed on the surface, but concrete products that enable mechanical and mass production of surface decoration concrete products It was desired to develop a manufacturing method and a manufacturing device for the same, and the applicant filed an application for a manufacturing method and device for a concrete product that mechanically and mass-produces concrete blocks with an exposed surface decoration. -315822).

[Problem to be solved by the invention]

However, because the conventional face plate does not have a structure that anticipates the input of filler aggregate, there are limits to the amount of filler aggregate, the size of decorative aggregate, the amount of mortar, etc.

In addition, with the conventional shape of the face plate, it is necessary to apply vibration each time filler aggregate, decorative aggregate, etc. are introduced, which requires a plurality of vibrating devices, which is uneconomical.

Furthermore, depending on the type of decorative aggregate, it is necessary to change the order in which filler aggregate and decorative aggregate are added, and it is not easy to rearrange the order in which they are incorporated on the -degree line.

Furthermore, since soft concrete is used in the pouring method, it is necessary to adjust the amount of filler aggregate and mortar as necessary.

Furthermore, when vibration is applied after adding filler aggregate or decorative aggregate, depending on the type of decorative aggregate, the decorative aggregate may move around a lot, and the more time it takes for compaction, the denser it becomes. However, due to vibration, the filler aggregate may rise and enter into the air bubbles in the concrete.

The present invention enables the amount of decorative aggregate, filler aggregate, and mortar to be freely adjusted, reduces the number of vibrators on the line, and allows the decorative aggregate to be appropriately positioned. Another object of the present invention is to provide a method for forming surface decorative aggregate that can be used economically and effectively.

[Means to solve the problem]

Therefore, as a result of intensive research to achieve the above object, the present inventors changed the shape of the face plate from the conventional dish shape.

A box body is provided at the bottom, the top surface has a tapered projecting surface, and if necessary, multiple drainage holes are provided at the bottom, and these are used to form a decorative concrete block. The present invention was completed based on the knowledge that it is possible to manufacture concrete blocks with an unprecedented superior surface finish both on-line and by the pouring method.

Although the drawings will be described in detail below, the present invention is not limited thereto.

In FIG. 1, reference numeral 1 indicates a formwork according to the present invention, which has a box body 2 at the bottom and a tapered upper surface.

The shape of the box 2 is not particularly limited, but in the case of a rectangular surface, for example, a rectangular cross-sectional shape, a trapezoidal shape, etc. are used.

The depth of the box body is determined as appropriate depending on the material of the decorative aggregate, materials, etc.

Further, as shown in FIG. 1, a hole 6 for draining water may be provided at the bottom.

Moreover, as shown in FIG. 4, the box part of the formwork can be used as a normal formwork by engaging a removable engagement plate.

At this time, it is preferable to attach and detach the engagement plate by providing a magnet or Velcro on the side of the engagement plate that contacts the bottom of the formwork so that the plate can be attached and detached freely.

Further, if an arbitrary pattern is provided on the surface of the engagement plate, when concrete is poured directly onto this, a decorative pattern can be provided on the surface of the concrete.

[Function] In order to form a surface-decorated concrete block using the formwork of the present invention, first, decorative aggregate is placed on the formwork 1, and then, after the first filler aggregate is placed, vibration is applied.

At this time, in the past, if the decorative aggregate was added first, special techniques were required for the charging method and vibration method when adding the filler aggregate, but with this formwork, this can be done. There is no need to do so, and the surface portion can be easily formed either on the line or in the pouring method.

In addition, if the formwork of the present invention is used, the filler aggregate and the decorative aggregate may be added in any order, or they can be added at the same time.

Furthermore, in the past, vibration was applied each time each aggregate was introduced, but with the formwork of the present invention, vibration only needs to be applied once after each aggregate is introduced.

Then, water or water containing a water-soluble adhesive is sprayed.

This is especially true when pouring North Ramp concrete with almost no moisture, which weakens the adhesion between the aggregate exposed on the surface and the cemented carbide concrete.
This is to make it easier to peel off the filler aggregate that is no longer needed.

Furthermore, when mortar or concrete is subsequently added, if the filler aggregate is more moist than necessary, there is a risk that the bonding will be poor.

Therefore, if a drainage hole is provided at the bottom of the face plate, the excess water will be drained from the hole and the moisture on the top surface of the face plate will be moderate.

After that, after applying vibration as necessary, cover the face plate with mortar as necessary, pour concrete, vibrate,
After compaction, it is demolded and cured to obtain a decorative concrete block.

Furthermore, instead of mortar, a mixture of paste or the like may be used.

In addition, the purpose of using aggregate for closing is to adjust the degree of roughness of decorative aggregate after molding, to evenly distribute the setting retarder when it is used, and to use aggregate for closing This prevents the setting retarder from penetrating deep into the concrete, and also prevents the surface of the concrete from appearing at the joints.

The present invention is a process in which the face plate and the concrete matrix are sequentially transferred on a line, in which filler aggregate, decorative aggregate, alignment mortar, etc. are supplied, and the face plate obtained in each process is A concrete block can also be manufactured by combining a concrete block matrix and a concrete block matrix.

The filler aggregate used in the present invention is sand.

Soil, slag, ore, shavings for surface decoration, synthetic resin, etc. may be used, and the size of the aggregate used is smaller than that of the aggregate for surface decoration. It will be done.

In addition, filler aggregates can be selected from a variety of colors to harmonize with decorative aggregates1. For example, granite shavings may be used for granite, or materials with completely opposite colors may be used. When used as a concrete block, it can be selected as appropriate depending on the location, purpose of installation, etc.

The surface decoration used in the present invention is not particularly limited.

It can be used for both large and small surface decorations, and the type is selected as appropriate depending on the purpose of the concrete block.

The present invention can be efficiently utilized in a pouring method, but is not limited thereto. Methods for supplying a face plate formed in a separate process to a concrete base include a method in which a face plate formed in a separate process is inverted onto a concrete base; Also, set the face plate to 18
How to rotate it 0 degrees and connect it to the concrete base,
Furthermore, the concrete matrix is, for example, 90 degrees or 13 degrees
Any method can be used, such as slanting it at a 5-degree angle and connecting it using arc movement.

Furthermore, concrete block forming machines use concrete depending on the purpose.

Therefore, when using the pouring method, soft concrete is used, but even cemented carbide concrete and concrete with large slump may be used as appropriate depending on the purpose.

〔effect〕

According to the present invention, the amount of decorative aggregate, filler aggregate, and mortar can be freely adjusted, and the degree of protrusion can be sufficiently adjusted.

In addition, since the moisture content can be adjusted, it is easy to combine with concrete and remove unnecessary filler aggregate after demolding.

Furthermore, the number of vibrators on the line can be reduced, reducing machine costs, and the appropriate vibration can be applied, so the decorative aggregate can be positioned appropriately, and the The order in which filler aggregates are added can also be freely set.

Moreover, since these can be introduced at the same time, costs can be reduced. - In addition, in the conventional pouring method, since soft concrete was used, it required skill to adjust it with decorative aggregate and filler aggregate, but with the present invention, it is easier to form, and the work is easier. Efficiency is also further improved.

Furthermore, since the face plate has a tapered overhang and a box-shaped bottom, the decorative material will not be located at the corners even after demolding, and the corners will not become weak.

Furthermore, conventionally, decorative aggregates that bond with concrete will not bond well if they are contaminated with dirt, so after cleaning the bonding surface,
They were placed on a pallet, but if you use this formwork with drainage holes, you can wash the pallet with water after placing it on the pallet, which reduces labor.

According to the present invention, by developing an excellent face plate,
It is possible to provide low-cost, superior surface decorative concrete products, especially stacking blocks.

Furthermore, since various surface decorations can be used on the surface, various designs can be created by combining them, so when used for residential land development, stone walls, and landscaping work, the natural texture and individuality can be achieved. In particular, it can reproduce a beautiful style, and when used in civil engineering works such as embankments, riverbeds, tunnel entrances, etc. in national parks and other parks, it harmonizes with the natural environment and contributes to environmental protection. I can do it.

Also, there is no longer any fear of pollution caused by industrial waste, which was the case in the past.
