Description

  The present invention relates to a road board material for a sidewalk that uses a wooden piece that is less tiring and less repulsive to a pedestrian's foot and has excellent water permeability.

Conventionally, a flat plate block used as a roadbed material for a sidewalk, a tree mat, a wall material for a building, or the like is generally known (see Patent Document 1).
In this known technique, a wood chip and a resin-based adhesive are kneaded and deposited, compression-molded, and the surface is similarly coated with a resin-based adhesive to form a film and dried.
In addition, each used material is composed of substances that can be recycled to the natural cycle after use, and has a natural color according to the used material and has a natural texture and a wooden pavement material using the same A paving method is known (see Patent Document 2).
This known technique mixes wood chips and / or wood fibers with an emulsion mainly composed of rosin and, if necessary, an emulsion containing other resins and fine aggregates, etc. By leveling, rolling and compacting, a wooden pavement having a natural color according to the wood material used and excellent in natural texture can be obtained.
In addition, there is known a laying block that has improved wear resistance and strength required as a road pavement material while ensuring water retention and water permeability (see Patent Document 3).
This known technique is made of water-permeable concrete with aggregates of crushed stone for roads with a particle size of about 0.6 to 5 mm on the surface layer, and cement and concrete admixtures with wood chips such as cypress adjusted to a particle size of 10 mm or less for the base layer. It is a multi-layered structure using wood concrete mixed with water.

  An object of the present invention is to provide a road board material for a sidewalk using a wooden piece that is less likely to get tired because of little repulsion to a pedestrian's foot and has excellent water permeability.

The road board material for the sidewalk of the present invention is a multi-layer integrated structure in which waste pieces and thinned wood are crushed and the shape and dimensions are adjusted, relatively small pieces are joined to the upper layer and relatively large pieces are joined to the lower layer. It is what.
The upper layer portion is obtained by kneading and depositing a wood piece having a length of 10 mm or less and a rubber-based adhesive, and compression-molding them into a block shape.
The lower layer portion is obtained by kneading and depositing a wood piece having a length of 10 mm to 30 mm and mortar cement, and compression-molding it into a block shape.
The road board material for a sidewalk of the present invention is a square wooden block (wood block), and is formed with a connecting step in which an upper layer portion and a lower layer portion are horizontally shifted in a vertical and horizontal direction or a diagonal direction.

Since the road board material for sidewalks of the present invention is entirely made of wood, it has high water permeability and can reduce rainwater into the soil, so it can be expected to suppress the heat island phenomenon, and it has cushioning properties that put a burden on the foot. Absent.
The road board material for sidewalks of the present invention is a square wooden block (wood block) in which a connecting step is formed between the upper layer portion and the lower layer portion, so that weeds are difficult to grow from the joint portion. Moreover, the wooden block (wood block) provided with the connecting step shifted in the vertical and horizontal directions or the diagonal direction can suppress the rising of the wooden block (wood block) due to the meshing effect of the two surfaces.
The weight of the road board material for sidewalks of the present invention is one-fourth the weight of conventional concrete products, has excellent effects such as excellent workability and work efficiency.

An embodiment of a road board material for a sidewalk according to the present invention will be described below with reference to the accompanying drawings.
1A is a front view and FIG. 1B is a rear view of a sidewalk road plate material of the present invention. FIG. 2: is (a) top view and (b) bottom view of the road board material for sidewalks of this invention. FIG. 3 is a (a) left side view and (b) right side view of a road board material for sidewalks of the present invention. FIG. 4 is a cross-sectional view taken along the line AA in FIG.
The road board material for sidewalks of the present invention is made by crushing waste materials such as waste panel, house demolition materials, pine worm-damaged trees, etc. Classification into a relatively small piece 1 and a relatively large piece 2 by, for example
The relatively small piece 1 is a wood piece having a length of 10 mm or less, and the relatively large piece 2 is a wood piece having a length of 10 mm to 30 mm.
As shown in FIG. 2, the sidewalk road plate material of the present invention is a square wooden block having a multi-layer integrated structure in which relatively small pieces 1 are joined to the upper layer portion 3 and relatively large pieces 2 are joined to the lower layer portion 4. Wood block).
As shown in FIGS. 1 and 3, a connecting step 5 having a structure in which the upper layer portion 3 and the lower layer portion 4 are horizontally shifted in the diagonal direction is formed.
Note that the connecting step 5 may be simply shifted horizontally in the vertical or horizontal direction.

As shown in FIG. 2 (a), which is a partially enlarged AA sectional view of FIG. 5, the upper layer portion 3 is obtained by kneading a relatively small piece 1 having a length of 10 mm or less and a rubber-based adhesive 6 to form a rectangular formwork. And it is compression molded into blocks.
In the upper layer part 3, since the small pieces 1 are relatively joined to each other at random, a minute gap is formed and water permeability is maintained.

As shown in FIG. 2 (a), a partially enlarged AA sectional view of FIG. 5, the lower layer part 4 is kneaded with a relatively large piece 2 having a length of 10 to 30 mm and a mortar cement 7 and deposited on a square formwork. Then, it is compression molded into blocks.
In the lower layer 4, relatively large pieces 2 are joined at random, so that an enlarged gap is formed and water permeability is maintained.

The upper layer portion 3 and the lower layer portion 4 may be separately molded with a mold, and both may be bonded together. Alternatively, the upper layer 3 and the lower layer 4 may be formed on a special mold with relatively small pieces 1 and A relatively large piece 2 may be deposited and simultaneously compression molded.
When the upper layer part 3 is formed thinner than the lower layer part 4, water permeability is improved.

When the road board material for sidewalks of the present invention engages the adjacent road board materials for sidewalks using the step 5 for connection, it is one-fourth the light weight of a conventional concrete product. It can be connected and has a structure in which weeds hardly grow from the joint.
The sidewalk road plate material of the present invention is a square wooden block (wood block) having a multi-layer integrated structure in which a relatively small piece 1 is disposed in the upper layer portion 3 and a relatively large piece 2 is disposed in the lower layer portion 4. Excellent, does not collect water, has cushioning and does not strain the foot.

It is (a) front view and (b) rear view of the road board material for sidewalks of this invention. It is (a) top view and (b) bottom view of the road board material for sidewalks of this invention. It is (a) left side view and (b) right side view of the road board material for sidewalks of this invention. It is AA sectional drawing of Fig.2 (a). It is a partially expanded AA sectional view of Drawing 2 (a).
