Description

TECHNICAL FIELD The present invention relates to a surface decorative concrete block manufacturing method which is particularly effective for a pouring method, and a surface decorative concrete block molding face plate.

[Conventional technology]

Conventionally, as a method of manufacturing a concrete product in which natural stone is exposed on the surface and finished, a method of embedding natural stone on the surface before hardening of concrete, fixing natural stone etc. with ice on a pallet, and then concrete or mortar etc. Installation method (Japanese Utility Model Publication No. 60-191405), concrete product in which concrete is poured from above the makeup aggregate, pressurized and vibrated, and then trained, and then fault separation is performed to reveal the laminated state on the makeup surface. There is a manufacturing method (JP-A-53-136028), etc., but with any of these methods, natural stone is easily peeled off after attachment, or when a large aggregate such as natural stone is used as a surface cosmetic material, It is impossible to produce a finished concrete product by exposing natural stone on the surface, which has a drawback that concrete does not bond well and natural stone is easily peeled off.

In addition, any of the conventional methods can be used only for relatively small, uniform shaped aggregates of cosmetics, and can be used for large decorative aggregates and cosmetic aggregates of various sizes. However, the protrusion of the irregularities of the decorative aggregate was very small.

Furthermore, in the conventional method, the surface of the concrete is inevitably exposed at the joints and the like, and it is inevitable that the product is given an artificial atmosphere.

Therefore, the present applicants have previously applied for a method for producing a concrete product whose surface is made up by exposing the aggregate (Japanese Patent Application No. 60-142813 and Japanese Patent Application No. 60-142814) (Japanese Patent Application Laid-Open No. 62-142814). 3902 and JP-A-62-3903).

Further, the method applied by the applicants made it possible to produce a concrete product in which the surface makeup was exposed on the surface, but the concrete product which enables mechanical and mass production of the surface makeup concrete product. It is desired to develop a manufacturing method and a manufacturing apparatus therefor, and the applicant has applied for a manufacturing method and a manufacturing apparatus for a concrete product that mechanically and mass-produces exposed concrete blocks having a surface makeup (Japanese Patent Application No. 62-62). -315822) (JP-A-1-156010).

[Problems to be solved by the invention]

However, since the conventional face plate does not have a structure in which the filling aggregate is expected to be input, the amount of the filling aggregate, the size of the decorative aggregate, the amount of mortar added, etc. are limited.

Further, in the case of the conventional face plate shape, it is necessary to apply vibration every time the filler aggregate, the cosmetic aggregate and the like are supplied, and a plurality of vibration devices are required, which is uneconomical.

Furthermore, depending on the type of cosmetic aggregate, it is necessary to change the order of introducing the sealing aggregate and the cosmetic aggregate, and it was not easy to change the order in which they were once installed on the line. .

In addition, in the pouring method, since soft concrete is used, it is necessary to adjust the amount of sealing aggregate and the amount of mortar as needed.

In addition, if vibration is applied after the filler aggregate and the cosmetic aggregate are thrown in, the cosmetic aggregate will dance greatly depending on the type of cosmetic aggregate, and the compaction will be denser as the time is longer. However, the filler aggregate may rise due to the vibration, and the filler aggregate may enter the air bubbles of the concrete.

The present invention, the amount of makeup aggregate, sealing aggregate and mortar can be freely adjusted, and the number of vibrators is reduced on the line, and the makeup aggregate is appropriately positioned, and in the pouring method. Another object of the present invention is to provide a method for molding a surface decorative aggregate that can be used economically and effectively.

[Means for solving the problem]

Therefore, as a result of earnest research to achieve the above-mentioned object, the present inventor has found that the shape of the face plate is changed from the conventional dish shape to a box body at the bottom, and the upper surface has a tapered protruding surface, and the box body is It has a detachable surface decorative forming plate, and if necessary, by providing a plurality of water drain holes on the bottom surface, it is possible to provide a surface decorative concrete molding face plate used in various construction methods. The present invention has been completed based on the finding that by molding a surface decorative concrete block using this, an excellent surface decorative concrete block can be produced on a line and by a pouring method, which has never been achieved.

Hereinafter, the drawings will be described in detail, but the present invention is not limited thereto.

In FIG. 1, reference numeral 1 denotes a mold of the present invention, which has a box body 2 at the bottom and an upper surface having a tapered protruding surface.

The shape of the box body 2 is not particularly limited, but in the rectangular face plate, for example, a rectangular cross section, a trapezoidal shape or the like is used.

The depth of the box is appropriately determined depending on the material and material of the decorative aggregate.

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

Further, by attaching a detachable surface decorative plate to the box portion of the form, it can be used as a normal form or used in various construction methods.

At this time, it is preferable that the surface makeup forming plate be attached and detached easily by providing a magnet or a magic tape on the surface side of the surface makeup forming plate which comes into contact with the bottom of the frame.

Further, if an arbitrary pattern is provided on the surface of the surface-decorated plate, when concrete is directly cast on the surface, the decorative pattern can be provided on the concrete and the surface.

[Operation] In order to mold the surface decorative concrete block with the mold of the present invention, first, the decorative aggregate is put on the mold 1, then the sealing aggregate is put, and then vibration is applied.

At this time, in the past, when the makeup aggregate was put in first, a special skill was required for the throwing method and the vibration method when the sealing aggregate was thrown in. It is not necessary, and the surface portion can be easily formed on the line and in the pouring method.

If the formwork of the present invention is used, the sealing aggregate and the cosmetic aggregate may be put in either order, or they may be put in at the same time.

Further, in the past, vibration was applied every time each aggregate was charged, but if the formwork of the present invention is used, vibration is sufficient only once after these aggregates are charged.

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

This is because there is almost no water when the concrete of North Lamp is put in, so the adhesion of the aggregate exposed on the surface and the cemented concrete becomes weak, and after the mold is removed, the unnecessary sealing bone This is because the material can be easily peeled off.

Also, when adding mortar and concrete afterwards,
If the sealing aggregate is moistened more than necessary, the bond may deteriorate.

Therefore, if a drain hole is provided at the bottom of the face plate, excess water is drained from the hole, and the moisture on the upper face of the face plate becomes appropriate.

After that, after adding vibration as necessary, if necessary, cover the face plate with mortar, place concrete, vibrate
After compaction, demolding and curing to obtain surface decorative concrete block.

It is also possible to use a mixture of paste and the like instead of mortar.

In addition, the sealing aggregate is used to adjust the degree of protrusion of the cosmetic aggregate after molding and to disperse the setting retarder evenly when a setting retarder is used. The set retarder can be exuded to the depths of the concrete, and the background of concrete can be prevented from appearing on the joints.

The present invention provides a process of sequentially transferring a face plate and a concrete matrix on a line, supplying a filler aggregate, supplying and aligning a cosmetic aggregate, and supplying mortar and the like, and obtaining a face plate obtained in each step. It is also possible to manufacture a concrete block by joining the base of the concrete block.

As the sealing aggregate used in the present invention, sand, soil, slag, ore, or shavings of surface makeup or synthetic resin may be used, which is smaller than the size of the surface makeup aggregate used. Is used and is appropriately determined depending on the type of the surface makeup aggregate.

In addition, in consideration of harmony with the cosmetic aggregate, a variety of colors can be selected for the filler aggregate, for example, using granite shavings for the granite, or one of the completely opposite color When used as a concrete block, it can be appropriately selected depending on its location, installation purpose and the like.

The surface makeup used in the present invention is not particularly limited, and it can be used from large to small surface makeup, and the type thereof is appropriately selected according to the purpose of the concrete block.

The present invention, which can be efficiently used in the pouring method, is not limited to this, as a method of supplying a face plate formed in a separate step to the concrete base, a method of reversing the concrete base on the face plate, Also the face plate 18
How to rotate it by 0 degrees and bond it to the concrete matrix,
Further, any method such as a method of inclining the concrete matrix at 90 degrees or 135 degrees and connecting it to the concrete matrix by using circular arc movement can be used.

In the concrete block molding machine, concrete according to the purpose is used.

Therefore, when the pouring method is used, soft concrete is used, but super-hard kneaded concrete and concrete with a large slump can be appropriately used depending on the purpose.

〔effect〕

According to the present invention, the amounts of cosmetic aggregate, sealing aggregate and mortar can be adjusted freely, and the degree of protrusion can be adjusted sufficiently.

In addition, since the water content can be adjusted, it is possible to easily combine with concrete and remove the unnecessary sealing aggregate after the mold is removed.

Furthermore, since it is possible to reduce the number of vibrators on the line and reduce the machine cost, and also to add appropriate vibration, it is possible to position the makeup aggregate appropriately, and It is possible to freely set the order of loading the sealing aggregates, and these can be loaded at the same time, so that the cost can be reduced.

Further, in the conventional pouring method, since soft concrete was used, it required a skill in adjusting the makeup aggregate and the sealing aggregate, but the present invention allows easy molding, and the work efficiency is improved. Is also improved.

Further, since the face plate has the tapered protrusion and the box-shaped bottom is provided on the face plate, the cosmetic material is not positioned at the corner even after the mold is removed, and the corner is not weakened.

Furthermore, conventionally, the makeup aggregate that binds to concrete deteriorates when dust is attached, so after cleaning the joining surface, it was placed on a pallet, but if you use this formwork with drainage holes, After putting it on the pallet, it can be washed from above the pallet with less labor.

According to the present invention, by developing an excellent face plate, it is possible to provide an excellent surface decorative concrete product at low cost, particularly a stacking block.

Furthermore, since a pattern can be provided on the surface of the surface makeup forming plate and various surface makeups can be used on the surface, various designs can be applied by combining it, so this can be used for residential land creation, stone wall, landscaping work. When used for, it is possible to lead a beautiful personality that beautifully reproduces the natural texture and individuality, and further, embankments, riverbeds, etc. in national parks and other parks.
When used for civil engineering work such as entrances and exits of tunnels, it can be in harmony with the natural environment and contribute to environmental protection.

In addition, there is no danger of pollution due to dust waste as in the past.
