Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when installing concrete blocks for pedestrian road boundaries, L-shaped retaining walls, gutters, etc., in order, the height positions of adjacent concrete blocks are aligned and gaps are eliminated. The present invention relates to an alignment adjusting device for an adjacent concrete block and an alignment adjusting method for aligning and adjusting those two concrete blocks.

[0002]

2. Description of the Related Art Conventionally, for example, when installing a concrete block for the boundary of a pedestrian road, first, the place to be installed is excavated and a crushed foundation stone is laid. Next, after the foundation crushed stone was compacted, leveling mortar was placed, and then the concrete block was placed thereon using a heavy machine.

However, in such a conventional installation method, it is not always possible to compact the foundation crushed stone into a perfect plane or to place the mortar into a perfect plane.
In some cases, the height position of the concrete block installed on it was different from that of the adjacent one. Also, when installing concrete blocks using heavy equipment, it was inevitable that there would be a gap between the concrete blocks so that they would not be damaged by hitting other blocks.

Therefore, conventionally, a concrete block is installed, and then a bar or the like is inserted under the concrete block and lifted up, and mortar is packed under the concrete block or the block is moved close to each other, and the height of two adjacent concrete blocks is increased. I was aligning the positions and eliminating the gaps.

However, in such a method, since the workability is poor, in the conventional concrete block installing method of this kind, as shown in FIG. 16, for example, as shown in FIG. 3 are embedded and opened downward, and male screw members 4 and 5 are respectively screwed in from below, and the male screw members 4.5 are placed on the smoothing mortar through the flat plate members 6 and 7, respectively, to make the smoothing mortar. There was a thing which installed concrete block 1 on the top.

After the installation, the height positions of the adjacent concrete blocks 1 are adjusted by rotating the male screw members 4 and 5, and the two adjacent concrete blocks 1 and 1 are aligned and adjusted. Pour,
The flat plate members 6 and 7, male screw members 4 and 5, and the lower portion of the concrete block 1 were embedded and fixed.

[0007]

However, in such a conventional method of installing a concrete block, the female screw members 2.3 must be embedded in the bottom of the concrete block 1 so that concrete does not enter the female screw members 2.3. However, the production of the concrete block 1 is troublesome, and there is a problem that the cost increases.

Therefore, an object of the present invention is to provide a method for installing a concrete block as described above, which has good workability, facilitates the production of the concrete block, does not increase the cost, and adjusts the alignment between the adjacent concrete blocks. Is possible.

In order to achieve the above object, an alignment adjusting device and an aligning method for adjacent concrete blocks according to the present invention have the following configurations.

That is, the invention according to claim 1 is an apparatus for aligning and adjusting adjacent concrete blocks, wherein the two concrete blocks are inserted into mutually adjacent recesses formed in two concrete blocks to be installed side by side. A support member is provided between the blocks, and the support member is movably supported in the vertical direction, and a screw member is provided to lift the concrete block by the movement to align the height positions of the two concrete blocks. , Is characterized.

According to a second aspect of the present invention, there is provided an alignment adjusting device for adjacent concrete blocks, which is installed side by side.
Two concrete blocks, each of which is provided with a support body which is inserted into a concave portion adjacent to each other and hung between the two concrete blocks, is movably supported in the lateral direction by the support body, and the concrete is formed by moving the concrete block. The present invention is characterized in that a screw member for pulling the blocks together to eliminate the gap between the two concrete blocks is provided.

According to a third aspect of the present invention, there is provided a method for aligning and adjusting adjacent concrete blocks, wherein two concrete blocks are installed side by side, and the two concrete blocks are provided in the mutually adjacent recesses formed in each of them.
