本発明は、天然石の大小塊石を表面に顕現して
化粧面層としたコンクリートブロツクの製造方法
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing a concrete block in which large and small natural stones are exposed on the surface to form a decorative surface layer.
従来本発明の意図する擁壁用や土止め用として

Conventionally, concrete blocks used for retaining walls and earthen walls as intended by the present invention have been formed by vibration and pressing using hard-mixed concrete with zero slump in order to take an immediate demolding method. There is.

つて見苦しい形状となる欠点を有していた。
However, when the bottom surface of the surface pallet is simply formed with unevenness, only a monotonous uneven pattern appears, which is far from the surface of natural stone. For this reason, it is possible to bury a large number of natural stone blocks and express it on the decorative surface of the block, but if vibration and compression are applied as a means of compaction during molding, the stone blocks will sink into the concrete and the surface will not be visible. In addition, even if it did appear, since hard-mixed concrete with zero slump is used, it has poor adhesion to the stone blocks and separates over time, forming holes, which can cause rainwater to enter the block. This not only causes damage such as cracks, but also has the disadvantage that the avatar surface becomes unsightly.
本発明者は、このような欠点を解決するため鋭

As a result of intensive research to solve these drawbacks, the inventor of the present invention laid a soft thick rubber plate on the bottom of the surface pallet, placed natural stone blocks of various sizes evenly on this, and Water is injected to infiltrate the surface of the stone block, and this surface pallet is placed in a formwork. After that, hard mixed concrete is poured into the mold as usual and compacted and formed by vibration and compression. be.

In this way, the present invention lays a thick soft rubber plate on the bottom of the surface pallet, places natural stone blocks of various sizes evenly on this rubber plate, and pours water from above to coat the surface of the stone blocks. The surface pallet is sufficiently infiltrated with concrete, placed in a mold, and hard mixed concrete is poured on top of the pallet and compacted by vibration and compression.

Moreover, since the part of the stone block that is in contact with the concrete is in a wet state due to water injection, the hard mixed concrete that is in contact with it absorbs water and becomes soft and blends well with the surface of the stone block, and after forming is completed. It adheres strongly to concrete and will not come off, and since the surface of the block is exposed to the surface of the stone block that is not in contact with the concrete that has been immersed in the soft rubber plate, there is no need to wash it out after molding. The color and texture of natural stone are expressed without any problem.

The method of the present invention will be explained with reference to the accompanying drawings.
The figure shows a thick soft rubber plate 3 on the bottom of the surface pallet 2.
This figure shows a cross-sectional view in which large and small natural stone blocks S are evenly arranged on a bed of stone, and water W is sprayed from above by a nozzle 12.
FIG. 2 also shows that a surface pallet 2 with water W sprinkled on large pebble blocks S as shown in FIG. 1 is installed in a formwork 1, and
It is a sectional view showing the state of the stone block S when concrete is poured from above and its gravity V is applied,
Approximately half of the stone block S is immersed into the soft rubber plate, and the rubber plate is deformed as shown in 3'. Further, FIG. 3 shows a molding machine using a split mold frame that is divided into left and right parts or a mold frame 1 that is integrally constructed. FIG. 4 shows a molding machine using an inverted mold. In the figure, 1 is a formwork, 2 is a surface pallet, 5 is a vibrator, 8 is a press plate, 10 is a formwork reversal shaft, and 11 is a press cylinder. Furthermore, FIG. 5 shows the demolded concrete block B.

必要もなく天然石の色合いや地肌が表現される。 In the present invention, as shown in FIG. 1, large and small natural stone blocks S are evenly placed on a soft rubber plate 3 laid in a surface pallet 2, and water W is poured over the blocks S. As a result, the surface of the block S is sufficiently wetted, and this surface pallet is placed in the form of the forming machine shown in Fig. 3 to form hard mixed concrete C.
When the stone block S on the surface pallet is loaded, the weight V of the concrete is applied to it, so that about half of the stone block S on the surface pallet sinks into the soft rubber plate 3 as shown in FIG. 2, and the rubber plate deforms as shown in 3'. (This figure 2 does not show the formwork or concrete for the sake of explanation.) In figure 3, the hard mixed concrete C that has been poured comes into contact with the part of the stone block S that is exposed from the rubber plate 3'. The exposed surface of the stone block S has been thoroughly infiltrated by water pouring, so it absorbs this moisture and becomes soft and conforms to the surface of the stone block S, and after forming, it firmly adheres to the concrete and becomes a stone. No lumps will fall off. Since the surface of block B is exposed on the surface of the stone block that is not in contact with the concrete immersed in the soft rubber plate, the color and texture of natural stone can be expressed without the need for special cleaning after molding.

動と圧縮によつて締固める。 FIG. 4 is an implementation diagram for the case of a reversible type formwork, and since the surface pallet 3 is reversed and coated, in the case of such a reversible type formwork, the formwork 1 is first removed. Hard kneaded concrete C is poured into the container, a small amount of water W is poured onto the surface of this concrete, stone blocks S for forming a decorative surface are placed evenly, and a small amount of water is sprinkled on the surface of the blocks S. Then, the surface pallet 3 on which the soft rubber plates 3 are laid is overturned from above and compacted by vibration and compression.

とがない。 Through this compaction, the surface of the lump stone is partially bitten into the rubber plate 3' and sealed, and the cement content of the hard mixed concrete, which has been softened by water from the top surface of the stone block and water W from the bottom surface during forming, is It does not go around the surface of the stone block.

In this way, the present invention lays a thick soft rubber plate on the bottom of the surface pallet, arranges natural stone blocks of various sizes evenly on this rubber plate, and pours water from above to coat the surface of the stone blocks. This surface pallet is placed in a formwork, and hard mixed concrete is poured onto it and compacted. When formed by this method, the stone blocks S are Because the weight of the concrete poured into the soft rubber plate 3 causes its surface to immerse into the soft rubber plate 3, there is no contact with the concrete in this part, and the part in contact with the concrete is in a wet state due to water injection. Therefore, the hard mixed concrete in contact with this becomes soft due to moisture content and blends well with the surface of the stone block.
また脱型養生後パレツトの取り外しに当つて
