[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement block laying method and a laying jig for use in the laying method.

[0002]

2. Description of the Related Art As a method of paving roads and plazas, roadbeds and subbases are sufficiently compacted and finished flat, and a sand cushion layer is formed by laying sand to a thickness of about 30 mm. After that, a method of laying a paving block made of concrete, brick, resin / ceramic composite, wood, etc. on the sand cushion layer is known, but conventionally, the paving blocks are arranged on the sand cushion layer. At that time, while observing a drawing in which a predetermined array pattern is drawn or by storing the above array pattern, the arrays are arrayed based on this memory.

According to the above-mentioned laying method, when one type of pavement block is arranged according to a simple arrangement pattern such as a staggered pattern, it can be laid according to a predetermined arrangement pattern without fail. If the unit pattern that is to be used is very complicated and the unit pattern includes a large number of two or more types of paving blocks having different shapes, it is difficult for the worker to store the unit pattern. It is necessary to arrange the pavement blocks one by one with the drawing showing the unit pattern and the neckline,
As a result, the efficiency decreased and the number of mistakes increased.

[0004]

SUMMARY OF THE INVENTION According to the present invention, as described above, the unit pattern which is the minimum repeating unit of the arrangement pattern of the pavement block is very complicated, and the unit pattern has a plurality of two or more types having different shapes. Provided is a paving block laying method and a laying jig for use in the laying method, which can easily and accurately arrange the paving blocks even when the paving blocks are included.

[0005]

That is, the first invention is
In the method of laying a pavement block in which a pavement block is laid on a sand cushion layer according to a predetermined arrangement pattern, protrusions are fixed on the lower surface of a see-through flat plate-like support frame made of a lattice or a transparent plate according to the above arrangement pattern The laying jig is pressed onto the sand cushion layer to draw the above arrangement pattern on the sand cushion layer at the lower end of the protrusion, and after removing the laying jig, it is drawn on the sand cushion layer. The pavement block laying method is characterized by arranging the pavement blocks according to the arrangement pattern.

A second aspect of the present invention is characterized in that projections are fixed to the lower surface of a see-through flat plate-like support frame made of a lattice or a transparent plate in accordance with an arrangement pattern preset for laying a paving block. This is a jig for laying a pavement block.

The support frame of the laying jig used in the first invention may be any one as long as the surface of the sand cushion layer can be seen through when the jig is placed on the sand cushion layer. It may be a resin plate or a lattice made of synthetic resin or wood. It is desirable that the size of the support frame be as large as possible in a range that one operator can hold in his hand and quietly place the sand cushion layer at a desired position. For example, when a light synthetic resin plate is used, it is preferable to make a rectangle with a length of 1 m and a width of 2 m.

The projections fixed to the lower surface of the support frame are used to engrave a desired arrangement pattern on the sand cushion layer, and the engraved arrangement pattern is composed of continuous straight lines or dotted lines. Any of the above, the projection can be made of a transparent or opaque plate and can be formed in a partition shape, and the lower surface thereof may be formed flat,
Further, saw-tooth-shaped irregularities may be formed. Further, the above-mentioned projection may be one in which a large number of nails are planted at predetermined intervals.
However, the thickness of the protrusions is preferably 2 to 4 mm, which is about the same as the gap provided between adjacent pavement blocks. Further, the height of the projections is only required to be such that a pattern on the lower surface of the sand cushion layer can be imprinted by pressing the lower surface of the projections, and 15 mm is sufficient.

Each of the sections surrounded by the projections corresponds to one pavement block, and the array pattern of the sections is the minimum repeating unit (unit) of the preset pavement block array pattern. It is preferable that at least one pattern) is formed. However, when the set unit pattern is too large to fit in one support frame, the unit pattern may be divided into a plurality of units and a plurality of laying jigs may form one unit pattern. .

[0010]

[Operation] By placing the laying jig at a predetermined position on the sand cushion layer and pressing it from above, the bottom pattern of the protrusions on the lower surface of the laying jig is transferred to the sand cushion layer,
The desired array pattern is drawn by imprinting. Therefore, the laying jig is moved above the adjacent portion of the transferred array pattern, and at this time, the supporting frame is arranged so that the lower surface of the protrusion of the boundary portion of the laying jig matches the boundary line of the transferred array pattern. While visually confirming from above, lay down and press the laying jig, and by repeating this, the specified array pattern is accurately transferred in a wide range, and the pavement blocks are arrayed according to this transferred array pattern. By doing so, laying as designed can be performed. When the height of the projection of the laying jig is set higher than the height of the pavement block, the array pattern can be drawn adjacent to the area where the pavement block has already been laid.
