Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a wooden frame constituting a flat paving block according to a first embodiment of the present invention.
Is a cross-sectional view of a state in which the paving material is filled in the wooden frame shown in FIG. 1,
FIG. 3 is a sectional view of a sidewalk on which the flat paving block according to the first embodiment is laid.

In these drawings, a flat plate block 1 for paving is, for example, a wooden frame 2 which is 300 mm on a side and has a thickness of 60 mm in plan view and is open at the top and bottom, and a pavement filled in the wooden frame 2. And concrete 3 as a material.

The above-described wooden frame 2 is formed by connecting four pieces of wood having the same length and structure, both ends of which are cut at an angle of 45 °, and functions as a locking portion at a portion serving as an inner peripheral surface of each piece of wood. A locking groove 2a having a substantially semicircular cross section is formed substantially at the center in the vertical direction along the longitudinal direction. In order to connect the four pieces of wood, the two pieces of wood are brought into contact with each other, and the two pieces of wood are sequentially connected with a round bar 2c (a type of fastener) that is driven into the upper and lower ends of the two pieces at approximately the center. Square. Note that the fastener may be a nail, a clasp, a slice plate, or the like, which functions similarly, instead of the round bar 2c.

The pavement material to be filled into the wooden frame is a concrete pavement material as well as a pavement material.
Asphalt, natural stone, rubber chips and the like can be used. Concrete or asphalt may be water-permeable, or may be a material obtained by pulverizing waste material such as concrete waste material into an appropriate size and mixing a binder.

Next, the production of the flat paving block 1 will be described. First, as shown in FIG. 2, after the wooden frame 2 is placed on the flat plate 11 serving as the bottom plate, concrete 3 is poured into the wooden frame 2, and the concrete is vibrated by a vibrator or the like to bring the concrete into the locking groove. To be fully penetrated. Then, the concrete is sufficiently cured in a state where it is filled in a wooden frame to form a flat paving block 1. That is, since the wooden frame functions as a mold, there is no need to remove the mold after curing.

When the concrete 3 is poured, a position slightly lower than the upper edge of the wooden frame 2 (a position above the locking groove 2a) is used as a casting surface, and the casting surface is formed by the upper edge of the wooden frame. The recessed portion is referred to as a base layer locking recessed portion 4. When a pattern, a character, or the like is applied to the upper surface of the flat plate 11, that is, a portion that comes into contact with the upper surface of the flat paving block 1 by, for example, unevenness, the pattern or the like is transferred to the upper surface (sidewalk surface) of the concrete 3. Can be.

Next, construction of a sidewalk will be described. First, an underlayer 21 laid with crushed stone, sand, or the like is formed on a portion where a sidewalk is to be constructed. Then, as shown in FIG. 3, the flat paving block 1 is laid on the base layer 21 vertically or horizontally with no gap or with a slight gap, with the side of the base layer locking recess 4 facing downward. Build the sidewalk by doing.

As described above, in this embodiment, the flat block for pavement 1 is made of the wooden frame 2 and the concrete 3, so that the flat block 1 can be manufactured easily and inexpensively, and the sidewalk on which the flat block 1 is laid can be used as a landscape. Thus, the wooden frame 2 can provide warmth to the pedestrian. And since the wooden frame 2 is only a surrounding part and a pedestrian mainly walks on the upper surface of the concrete 3, all are excellent in abrasion resistance compared with a wooden sidewalk, and the service life is thereby improved. Also,
Even if it gets wet with rainwater, it is possible to secure the slip resistance. In addition, if the upper surface of the wooden frame 2 is inclined downward toward the outside, the shoe sole of the pedestrian is unlikely to contact, so that the wear resistance can be further enhanced. In addition, since the wooden frame 2 functions as a mold, there is no need to manufacture a separate mold for manufacturing the pavement flat block 1, and the manufacturing equipment can be simplified.

Further, since the underlayer retaining recesses 4 are provided below the pavement flat block 1, the base layer 21 enters the underlayer retaining recesses 4 by laying, so that the displacement of the flat block 1 can be reduced. Unevenness can be prevented and walking becomes easier. Since a predetermined design can be applied to the sidewalk surface of the concrete 3, the pavement surface can be changed. Further, since the pavement flat block 1 has a square shape in a plan view, a sidewalk can be easily constructed simply by laying so that each side abuts.

Next, a second embodiment of the present invention will be described. FIG. 4 is a perspective view of a wooden frame constituting the flat paving block, FIG. 5 is an explanatory view showing fasteners and couplings, and FIG. 6 is a plan view of a sidewalk on which the flat paving block of the second embodiment is laid. 7 is a cross-sectional view of the sidewalk shown in FIG. 6, FIG. 8 is an explanatory view of a state where the pavement plate blocks are connected by a connecting tool,
The same or corresponding parts as those in FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof is omitted.

In these drawings, reference numeral 1 denotes a plate block for paving, 2b denotes a concave portion provided on a part of the outer peripheral surface of each side of the wooden frame 2, and the concave portion 2b is a wooden frame 2 laid next to the wooden frame 2.

At this time, as shown in FIG. 8, each piece of the connecting tool 2f is made to penetrate into the insertion groove 2e of the adjacent fastener 2d, and the adjacent pavement plate blocks 1, 1 are connected to each other. Then, a cassette-type water-permeable member 5 is mounted (fitted from above) in a housing portion formed by combining the concave portions 2b of the two adjacent wooden frames 2 and, for example, sand is filled so as to fill other gaps. Filling, which can build a sidewalk.

The flat paving block 1 according to the second embodiment.
Also in this case, effects such as giving a warm feeling can be obtained as in the case of the pavement plate block 1 of the first embodiment.
Since the permeable member 5 is disposed between the pavement flat blocks 1, the rainwater falling on the pavement flat block 1 can permeate through the permeable member and penetrate into the underlayer 21. Features make walking easier. further,
Since the pavement flat blocks 1 and 1 are connected to each other by the connecting tool 2f, displacement and unevenness can be more reliably prevented.

When the water permeable member 5 is clogged and the function of permeating rainwater is reduced, the water permeable member 5 may be removed from the housing and a new water permeable member 5 may be attached to the housing. Then, the water-permeable member 5 removed from the housing portion can be restored to the water-permeability by washing by, for example, passing water under pressure from the bottom side to the front side.

In the above embodiment, the planar shape of the flat paving block 1 has been described as a square in plan view.
Other shapes such as a rectangle and a hexagon may be used. Also,
The locking groove 2a as a locking portion is provided on the inner peripheral surface of the wooden frame 2 so that the paving material does not come off. However, if the paving material is locked by the locking portion and does not come out of the wooden frame 2, the groove is formed. Not limited to a protrusion,
In addition, locking portions (may be concave portions) may be provided in a dotted manner. Further, the wooden piece of the wooden frame 2 is not limited to the one whose end is cut at an angle of 45 °, and any connection form may be used as long as the wooden piece can be assembled as a frame body whose top and bottom are open. For example, it is also possible to combine a wood piece having a cut-out upper half and a cut-out lower half with nails or screws from below (splicing two pieces). In this case, it is desirable that the locking groove 2a is formed above or below the center of the height of the inner surface. In addition, in addition, three-disc set,
A so-called rope combination may be used.

As described above, according to the present invention,
The following effects are obtained. According to the first aspect of the present invention, since the flat paving block is formed of the wooden frame and the paving material filled therein, it is easy to manufacture and can be provided at low cost. Then, the wooden frame functions as a joint material, becomes a sidewalk suitable for the scenery, and the wooden frame can provide warmth to the pedestrian. And since the wooden frame is only the surrounding part,
Compared to the case where a wooden flat block is laid as a whole, the wear resistance is superior and the service life is improved. In addition, since the wooden frame functions as a mold, a mold for manufacturing the flat paving block is not required.

According to the second aspect of the present invention, since the base layer locking recess is provided below the pavement flat block, the base layer enters into the base layer locking recess by laying, so that displacement and slippage can be prevented. Unevenness can be prevented and walking becomes easier.

According to the third and fourth aspects of the present invention, the wooden frame is provided with a concave portion formed on the outer periphery of each side to form a receiving portion by complementing with the wooden frame of the adjacent flat plate block. When filling the inside with a permeable material such as permeable asphalt,
Rainwater that has fallen on the pavement flat block can flow to the underlayer, preventing rainwater from accumulating on the upper surface and suppressing slippage during rainfall.

According to the fifth aspect of the present invention, since the water permeable material is detachably fitted into the housing portion, when the water permeability is reduced, the water permeable material is replaced with a new water permeable material or is removed and clogged. It is possible to recover the water permeability by removing the dust and the like. Therefore, recovery of the water permeability function is easy.
