[0004] Concrete products formed by the conventional compaction are concrete products which are compacted by the vibration of the formwork and pressing force from above, and are not uniformly transmitted to the entire formwork. Was being manufactured. Therefore, in the case of a mold having a complicated shape only by compressing the concrete from above while applying vibration to the mold, the pressing force from above is not transmitted to the lower part of the protruding portion in the mold. That is, the weakened portion of the pressing force has a defect that the compaction of the concrete is incomplete and a rough portion is generated.

[0005] In recent years, a product has been developed which has been actively developed in which natural stone is exposed on the surface of a concrete product to match the surrounding scenery. In this conventional molding method, the concrete and natural stone are incompletely fixed together and are pulled out from the concrete surface and fall off, or the molding during the molding is carried out. There was a drawback that the whole stone was buried, and the expected product could not be obtained.

For this reason, even if the shape of the concrete product is complicated, the combined vibration of the form vibration and the independent vibration from the bottom surface is effectively transmitted to the entire stiff concrete in the form, and from both sides. The compaction of concrete in the formwork by compressing concrete by pressing up and down and pressing up and down from up and down and up and down from below to uniformly compact the entire concrete in the formwork at high speed. Can be eliminated. In addition, even when embedding natural stone or artificial stone in the surface of the concrete product, or when filling sand particles for joint formation between these stone blocks, the stone is extremely easily and securely fixed by the above-mentioned forming method. Therefore, there is no extraction or falling off of stone blocks and sand particles.

In the case of forming a natural stone or artificial stone block and sand particles for forming joints on the exposed surface of a concrete product, an appropriately shaped stone block and sand particle layer are laid in a surface pallet. When molding is performed by the above-mentioned molding method using a surface pallet that has been wetted by spraying water from above, the stone mass protruding above the sand particle layer and the upper surface of the sand particle layer are pushed up from below and compressed. Due to the shaking, the hardened concrete is softened by the moistened water of the stone mass and the sand grain layer to increase the fixation, so that the stone mass and the sand grain after hardening of the concrete do not come off and fall off.

In addition, large and medium-sized mixed stone blocks of natural stones and artificial stones are juxtaposed on a surface pallet having a large number of pores for drainage formed on the bottom surface thereof on the surface of the concrete product. The sand grains that form the joints between them are filled and laminated to an arbitrary thickness, and an appropriate amount of water is sprayed from above to wet the stone blocks and the sand grain layer, to improve the adhesion to concrete, and to spray excess water that has been sprayed. By draining water through the sand layer from the pores at the bottom of the surface pallet, the sand layer is compacted to prevent the penetration of cement base during molding and stabilize the stone mass. The surface pallet treated in this manner is installed at the bottom of the formwork, and the stone layer and the upper layer of the sand grain layer at the joint forming portion are partially embedded in the concrete by the molding method described above, and a part of the surface layer is exposed as a product surface. Put out.

In this conventional compacting method, the vibration pressure is not evenly distributed over the entire concrete material, and there are strong places and weak places, so that a compact product is produced in compaction. The compacted concrete of the present invention has a double-structured formwork, and the material is widened and the material supply is widened. The product processing that is compacted by complex vibration and immediately removed from the mold with a surface pallet downward is a labor-saving process that carries out product transfer and the next surface pallet supply in one step, and has an epoch-making effect. As a molded product, a homogeneous concrete product without variation can be obtained.

The stone and the upper layer of sand protruding from the sand grain layer are buried in concrete by pushing up to the position (line a to line b in the drawing) , pinching from both sides, form vibration and independent vibration from below. On the other hand, the sand particles during pre-treatment are moistened with moisture, so that the hardened concrete is slightly softened at the point of contact with the hardened concrete, and the exposed stone mass and the sand particles are more closely adhered and the hardened concrete is extracted. Almost half of the exposed stone mass is buried in concrete and half is exposed on the surface, and the upper layer of the sand layer is fixed in the concrete and the surface pallet is completely peeled off when the surface pallet is peeled off. After the concrete is hardened and does not adhere, the concrete pallet is peeled off after the hardening of the concrete. Therefore, the sand particles are separated into the exposed stone surface and the sand particles remaining in the surface pallet are reused.
