Description

  The present invention relates to a method, a manufacturing apparatus, and a manufacturing apparatus for a paving stone-like floor surface forming block used for forming a paving stone-like floor surface on a road such as a sidewalk, a roadway, a ground such as a park or a plaza, a floor of a building, a wall, etc. The present invention relates to a method for laying a formwork and a concrete block.

  In general, asphalt and concrete are often used as paving materials for pavement such as roads and open spaces such as sidewalks, roadways, etc., but the pavement surface by these pavement materials is unattractive and lacks design. .

  On the other hand, natural stone is processed into a flat shape to form a paving stone, and this paving stone is paved by paving this paving stone. This paving method using paving stones has a problem that the masonry lays the paving stones while cutting them into a predetermined shape, so that even if a quaint paving surface can be obtained, the construction is difficult and requires a lot of time.

  Therefore, it has been proposed that instead of using natural stone as a paving stone, a concrete block having a predetermined shape is prepared as a unit element, and by combining this, the work efficiency when laying the concrete block as a paving stone is improved ( (For example, see Patent Documents 1 to 4)

  However, although the conventional concrete block can improve the workability, the shape of the block is complicated or it is necessary to prepare a concrete block with a different shape. There is a problem that it is not possible to dramatically improve workability because it is necessary to combine blocks so as to play a jigsaw puzzle while considering which side of each other matches. Further, the conventional method has room for improvement in view of the production cost and production efficiency of the concrete block.

An example of the shape of a concrete block (hereinafter also simply referred to as a block) in the present invention will be described with reference to FIG.
What is shown in FIG. 1 is a figure which shows the aggregate | assembly of the unit block of the state removed from the formwork manufactured by the manufacturing method of the concrete block of this invention.

In FIG. 1, each unit block is shown as type 1-12. The gaps between the unit blocks and the outer periphery of the block aggregate indicate the locations where the molds have been removed. This block aggregate is formed on an iron plate by placing a mold on an iron plate to be a bottom mold, filling a mold with concrete, and removing the mold after press molding.
FIG. 2 is a view showing a state in which a concrete block aggregate is formed using a mold in the manufacturing method of the present invention.
At the time of molding, the mold frame 21 is placed on the bottom mold 22 made of an iron plate, the concrete is filled into the mold frame 21 and pressed, and then the concrete block aggregate 5 is placed on the bottom mold by die cutting. Form.

Types 1, 2, 3, 4, 10, 11, and 12 are basic blocks having the same shape. The shape of the side surface of each side of the basic block has a shape that makes contact with another side of the basic block without causing a gap.
The shape of the basic block shown in FIG. 1 is an irregular hexagon, and two adjacent sides are set as one set, and three sets are combined to form the outer periphery. Each pair of adjacent two sides has a shape and size in which one side is reversed with respect to the other side so as to form a complementary shape so that no gap is generated when the two sides are abutted. In addition, each set of two adjacent shapes is different from the shape and size of two adjacent sides of another set.
The narrow groove-like lines on the surfaces of types 2, 3, 4, 10, 11, and 12 are pseudo joints (joint finish grooves) formed as recesses on the block surface, and the pseudo joints finish the floor surface in a turbulent paving stone style. Is for.

As shown in FIG. 1, centering on type 1, six basic blocks of types 2, 3, 4, 10, 11, and 12 have one side that can be butt-contacted with one side of type 1 of type 1. It is formed so as to face one side.
The types 5-1, 5-2, 6-1, 6-2, 7-1, 7-2, 8-1, 8- are provided so as to surround the types 1, 2, 3, 4, 10, 11, 12. 2, 9-1 and 9-2 are formed.
The types 5-1 and 5-2 are shapes obtained by dividing the type 2 into two in the vertical direction, the types 8-1 and 8-2 are shapes obtained by dividing the type 11 into two in the vertical direction, and the type 7-1. 7-2 is a shape obtained by dividing Type 1 into two in the vertical direction.
In addition, types 6-1 and 6-2 and types 9-1 and 9-2 have shapes obtained by dividing type 1 into two in the horizontal direction.
Hereinafter, types 5-1, 5-2, 6-1, 6-2, 7-1, 7-2, 8-1, 8-2, 9-1 and 9-2 are referred to as auxiliary blocks.
The pseudo joint can be given an appropriate shape for each basic block and each auxiliary block.

The present invention is characterized in that the basic block and the auxiliary block are simultaneously formed by a single molding operation.
That is, in the conventional molding method, as shown in FIG. 5, only the basic block is molded by a single molding operation. The reason is that the auxiliary block is useful as a curb block for curbs or a corner block for corners, but its demand is much less than that of the basic block. This is because there is a lot of waste. For this reason, the curb block or the corner block is actually produced by cutting the basic block on site.

The present invention pays attention to the fact that the auxiliary block has a shape obtained by dividing the basic block into two, and intends to effectively use this as an equivalent to the basic block.
That is, for example, regarding type 5-1 and type 5-2 auxiliary blocks, type 5-1 and type 5-2 each have a shape obtained by dividing a type 2 basic block into two. Therefore, when the type 5-1 and the type 5-2 are abutted with the respective divided surfaces facing each other, the shape of the basic block is obtained.

Similarly, a combination of type 6-1 and type 6-2, a combination of type 7-1 and type 7-2, a combination of type 8-1 and type 8-2, a type 9- A combination of 1 and type 9-2 also has the shape of a basic block.
Hereinafter, basic blocks of types 1, 2, 3, 4, 10, 11, and 12 are referred to as basic blocks A, and a basic block shape formed by combining two auxiliary blocks is referred to as a basic block B. The arrangement of the basic block A and the basic block B in the upper left block of FIG.

  If a plurality of block assemblies shown in FIG. 1 are connected as they are in the vertical direction or the horizontal direction, the area of the paving stone portion of the basic block shape can be increased. Such a state is shown in FIG. As shown in FIG. 3, when a plurality of block assemblies are directly connected in the vertical direction or the horizontal direction, linear joints a and b are formed between the block assemblies. Such straight joints impair the taste of turbulent paving stones.

For this reason, when laying the basic block B, the basic block A is used in place of the basic block A so that the straight joints do not appear.
FIG. 4 replaces some of the blocks in the four block aggregates shown in FIG. 3 so that straight joints do not appear. Double arrows in FIG. 4 indicate that the blocks are exchanged.
As is clear from the comparison between FIG. 3 and FIG. 4, there is no linear joint appearing on the paving stone attached by replacing the basic block B with the basic block A, and the line of the butted portion of the basic block B is Since it has the same effect as a pseudo joint, it does not impair the taste of turbulent paving stones.

  Also, as shown in FIG. 1, by simultaneously forming the basic block and the auxiliary block, not only the advantages in the manufacturing process as follows, but also the area of the block to be formed at a time increases, so the manufacturing cost is reduced. It can be greatly reduced. This advantage will be described below.

Conventionally, only the basic block is formed as shown in FIG.
After this molding process, the molded body is transferred to a drying room (curing room) while being placed on the iron plate, and then the basic block is transferred from the iron plate to the pallet for drying.
As the pallet, a secondary curing drying pallet may be used, or a shipping pallet also serving as a drying pallet may be used. Moreover, as a material of the pallet, a wooden pallet or a plastic pallet can be preferably used.
When moving the basic blocks from the iron plate to the pallet, the basic blocks on the iron plate were pressed and gathered from the side to close the basic blocks without gaps formed by the formwork, and then gathered together The basic block aggregate is pressed and clamped from the side by a clamping device and loaded on a pallet. At this time, in order to improve work efficiency, the basic block aggregates collected on another iron plate are further stacked on the basic block aggregates loaded on the pallet to form a two-tiered stack. There are also cases where they are pressed together in the horizontal direction.

In the case of performing transfer by pressing and clamping with the clamping device in this way, the block assembly is composed of only the basic blocks as shown in FIG. It is not easy to press and hold or to stack two or more layers.
On the other hand, the block aggregate composed of the basic block and the auxiliary block shown in FIG. 1 has a linear shape and a substantially square outer edge, so that the block aggregate can be easily pressed and clamped by a clamping device. It becomes possible to stack more than one step.

In the above description, the concrete block having the shape shown in FIG. 1 has been described as a specific example, but the shape of the block is not limited to this.
The shape of the basic block has a shape in which one side can be matched with one side of another basic block, and when the concrete block is molded so that the whole is a square shape, the central part has a plurality of identical shapes. As long as the auxiliary block in the peripheral portion has a shape obtained by dividing the basic block into two, it is sufficient.
For example, what is shown in FIG. 1 is an irregular hexagonal shape, but may be a regular hexagonal shape or a hexagonal shape having a major axis and a minor axis.
