Abstract

PURPOSE:To make the pavement of road surface easier as well as manifest the effect of blind-person induction by a method in which spacers are provided to the peripheral side walls of zig-zagged pavement blocks and projections to be easily sensed by the sole of foot are formed on the surface of the pavement blocks. CONSTITUTION:Spacers 3 such as projections are projectionally formed vertically on the side walls of zig-zagged pavement block A and projections 4 and/or long projections are projectionally formed on the surfaces of the block A, where the projections 4 are set in such a way as to support the sole oo foot on three points always even on any position and also the long projections are formed within the size of the sole in such a way as to sense them exactly by the sole of foot. The blocks A are set adjacently with a fixed small spacing by the spacers 3, and sand is packed into the apertures and compacted, followed by paving the road surface.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a paving block used for paving roads, gardens, plazas, parking lots, etc.

(Prior Art) As a prior art to the present invention, there is an invention described in Japanese Patent Application Laid-open No. 132801/1983 filed by the applicant of the present invention.

(Problem to be Solved by the Invention) However, in this conventional paving block, since the peripheral side wall of the block formed in a zigzag shape is flat, a small gap (joint) is provided between the blocks, and the small gap When filling a large number of blocks with sand, the peripheral walls of the blocks may come into contact with each other, making it impossible to fill the joints with sand, and the joints may become uneven, resulting in an unsightly appearance.

Furthermore, small protrusions or long protrusions are provided on the top surface of the block, but in order to expect acupressure effects from the soles of the feet, these protrusions are small in diameter and low in height, and cover the top surface of the block. It is made up of a large number of protruding pieces, and does not have the effect of guiding blind people.

(Means for Solving the Problems) A block body formed in a zigzag shape is integrally provided with a s(he)-sah formed of a protrusion on the peripheral side wall in the vertical direction,
In addition, the several protrusions protruding from the top of the block are arranged to support the sole of the foot at three points at any position, and the length of the long protrusion is set to the same size as the sole of the foot so that it can be felt reliably by the sole of the foot. The above-mentioned problem is solved by forming the wafer within the range of 100 to 200 m.

(Actions and Examples) Embodiments of the present invention will be described along with their operations along with the drawings.

1 to F[, As shown in FIG. 4, the long side side of a rectangular plate having a predetermined wall thickness is
The parallel lines and two parallel diagonal lines of the book form a continuous zigzag-like uneven surface (1), and the short side surface also has two parallel lines and one diagonal line connected in plan view. A block body is formed by forming a zigzag-like uneven surface (2),
Moreover, the uneven surface (1) has two places, and the uneven surface (2)
A spacer (3) is formed by providing a longitudinally rectangular protrusion at one location, respectively.

Furthermore, there are several saucer-shaped protrusions (4) on the top surface of the block.
... to form a paving block A.

Here, the spacer (3) maintains a small gap between blocks when connecting the blocks, and the spacer (3)...
)... is an arrangement in which the sole of a blind person's foot is supported at three points at any position, in a so-called checkered pattern.

As shown in Fig. 5, another embodiment of the paving block A is one in which protrusions A having a smaller diameter than the protrusions (4) are protruded from the upper surface of the block body at appropriate intervals. It is.

Further, as another embodiment, as shown in FIGS. 6 to 8, both ends of the block body are formed in a semicircular shape in plan view, and the length is within the size of the sole of the foot. Two semicircle-shaped long protrusions (5) are provided in parallel to form a paving block.

As another example, as shown in FIG. 9, the uneven surfaces (1) of the paving block A are joined together to form a paving block 8 whose size is doubled.

In addition, as another example, as shown in FIG. 10, four long protrusions (5) having the same size as the block body of the paving block B are provided in parallel on the upper surface of the block body. Form a paving block g.

Furthermore, as shown in Fig. 11, as another example of a paving block with an enlarged block body, the upper surface of the block body is divided into two, and two long protrusions (5) (5) are placed on the safe side when walking. In addition to protruding in parallel, there is a protrusion (4) on the dangerous side...
Pavement blocks are formed by protruding in a checkered pattern.

In each of the above embodiments, the spacers (3) are provided to protrude in the vertical direction of the block body, but their length and number are not limited, and their specific shape is not limited either.

When the paving blocks A thus formed are laid in the valley stacking method as shown in Fig. 12, as shown in Fig. 13, there are spacers (3) of the block bodies that overlap each other on the sides of the block bodies. ... come into contact with each other to ensure a certain small gap between them, and this small gap is filled with sand (6) and the upper surface of the block body is rolled to make it flat.

Then, around the paving block A, the accessory blocks C... are arranged in a row except for the corners, and other accessory blocks D or Takumi are fitted into the corners, Furthermore, a supplementary accessory block E is fitted into the space surrounded by the paving block A, the accessory blocks c, c, and the accessory block D, and the space is also surrounded by the paving block A and the accessory block C. The road surface is paved by fitting the accessory blocks E into the spaces created by this.

(Effects of the Invention) As with the ridges, the present invention can easily and quickly form a sturdy and beautiful paved surface on any terrain by combining paving blocks and accessory blocks. can be,
The small gaps formed between the paving blocks and between the side surfaces of the paving blocks and the utility blocks are filled with spacers (3) and
... ensures constant and accurate spacing, so the sand (
6) It is easy to fill, and when the top surface of the block is rolled after paving, the top surface of the block is made flat, and each block is laid accurately and orderly, and the block connecting parts maintain uniform intervals. The finish is beautiful.

In addition, surface water permeates underground through small gaps filled with sand (6) and is returned as groundwater, providing natural irrigation to plants. Therefore, there is no risk of flash floods flowing across the paved surface, and there is no need for large drainage channels.Furthermore, the paved surface is flexibly connected, and the concentrated load is distributed without being applied to a specific location, so the paved surface can be damaged. I don't.

Furthermore, several protrusions (4) and long protrusions (5) are provided on the upper surfaces of the paving blocks and accessory blocks to form a guide surface for blind people. It is in contact with the protrusion (4) and is supported at three points, so it is stable, and since the long protrusion (5) is formed within the size of the sole of the foot, it properly contacts the sole of the foot and the toes are supported. It locks onto the tip of the long protrusion (5) and kicks well, allowing safe passage.

Moreover, it is possible to form a paved surface that is easy to color and colorful, and is extremely durable and semi-permanent.

As described above, the present invention is an excellent and useful invention that can be constructed easily and quickly, and the blocks themselves can be mass-produced at low cost.
