Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a paving utility block used for paving roads, gardens, plazas, parking lots, etc.

(Conventional technology) The conventional technology for yakubutsu blocks is
-There is an invention related to Publication No. 132801.

This accessory block consists of a substantially pentagonal plate whose upper side of a quadrilateral in plan view is formed into a mountain shape, and only the two sides connected to the mountain shape are formed into zigzag-shaped curved surfaces. .

(Problem to be solved by the invention) However, in this conventional accessory block, the two side faces facing each other on the left and right sides are formed in a straight line, so it is difficult to arrange the blocks in rows around the paved surface. However, if a basic block forming the main part of the paved surface is arranged inside the accessory block,
The zigzag-shaped peripheral side wall of the basic block and the zigzag-shaped side surface provided on the chevron-shaped portion of the accessory block fit in a concave-convex manner, but the side surfaces of the accessory blocks only touch each other in a straight line.

Therefore, since the shape resistance between the accessory blocks is small, the blocks often slide and create staggered steps on their upper surfaces, and there is a risk that the blocks may slip out toward the outer circumference of the paved surface.

Furthermore, since the top surface of the block is flat, when a guideway for blind people is provided, it is necessary to separately manufacture a braille board for guiding blind people and attach it to the paved surface.

(Means for Solving the Problems) In a pentagonal plate body formed by protruding one side of a quadrilateral in a plan view into a mountain shape, or an accessory block in which the side wall forming the mountain shape of the plate body is formed into a curved surface,
The side walls located opposite to each other on both the left and right sides of the plate body are
A paving accessory block formed on an uneven surface in which two parallel lines and zigzag-shaped sides formed by connecting the parallel lines with diagonal lines face each other in parallel, and an upper surface of the paving accessory block. By providing a paving accessory block on which several protrusions or long protrusions for guiding blind people are provided, the blocks fit together perfectly and form a paved surface with no discrepancies at the joints. In addition, protrusions and long protrusions are provided on the pavement surface to help guide blind people safely.

(Operations and Examples) Examples of the present invention will be described together with their operations based on the drawings.

1 to 5 show an embodiment of the present invention,
In plan view, the lower wall of the plate-shaped body is a linear flat surface 1, and the two left and right side walls connected upward from both ends of the flat surface 1 are defined by two parallel lines a and c, and the parallel lines It is formed into a zigzag-shaped side connecting a and c with a diagonal line b, and the lines a and a, c and c, and diagonal lines b and b are formed on uneven surfaces facing each other in parallel. .

At the upper ends of the two side walls, there are two parallel lines d,
d is connected by one diagonal line e, and two other parallel lines f and f are connected by one diagonal line g, so that each is bent in a zigzag shape, and lines c and d , c and f and d and f are made to be continuous, respectively, thereby forming an upper wall having mountain-shaped uneven surfaces 2, 2.

A paving accessory block A is formed by protruding hemispherical projections 3 for guiding blind people on the upper surface of the plate.

Incidentally, on the peripheral side wall of the plate of the paving accessory block A, spacers 4 made of ridges or the like are provided to protrude in the vertical direction.

This paving accessory block A is arranged in a row around the paved surface, but the main part of the paved surface has a seventh block.
A basic block B is laid, as shown in many figures, whose circumferential side wall is bent in a zigzag shape, and whose circumferential side wall is provided with spacers such as protrusions.

As an example of its installation, as shown in the same figure, blocks are laid in rows in a valley-stacked manner, and the spacer is connected to the side of another basic block B to maintain a constant small gap between both blocks. to hold.

In addition, in a part of the basic block B, a basic block B for guiding the blind person, which has protrusions 3 for guiding the blind person projected on the upper surface as shown in Fig. 6, is arranged in a row to create a guideway for the blind person. It can also be formed.

The paving accessory blocks A according to the present invention are arranged in a substantially frame-like manner by fitting two zigzag-like uneven surfaces so as to surround the basic blocks B... Spacers 4 are provided between the side surfaces and between the side surfaces of the paving accessory block A and the basic block B to maintain a constant small gap and pave the road surface.

Here, the small gap formed between the side surfaces of the block is secured by each spacer 4 to ensure a constant and accurate gap, so it is easy to fill with sand, and the top surface of the block can be rolled after paving. When pressed, the top surface of the block is made flat and each block is laid accurately and orderly, so that the block connecting portion maintains uniform gaps and has a beautiful finish.

In addition, surface water percolates underground through small gaps filled with sand and is returned to groundwater, providing natural irrigation for plants. Therefore, there is no risk of flash floods flowing on the paved surface, and there is no need for large drainage channels. Furthermore, since the paved surface is flexibly connected and the concentrated load is dispersed without being applied to a specific location, it has the effect of preventing destruction of the paved surface.

Incidentally, at the corner of the road surface, there is provided a corner corner having a shape as shown in FIG. Accessory block C is fitted as shown in FIG. In addition, at the corner portion where the area occupied by the corner portion is smaller than the area occupied by the accessory block C, a spacer 4 having a shape as shown in FIG. is fitted with an accessory block D having protrusions 3....

Furthermore, as shown in FIG. 7, there is a part surrounded by paving utility block A and basic block B, with a space between them, and a part surrounded by paving utility blocks A, C and basic block B. The empty spaces between the two are filled with accessory blocks E in the shape of windmills.

Furthermore, instead of the protrusions 3 protruding from the upper surface of the block, long protrusions for guiding blind people may be protruded, or protrusions and long protrusions may be used together (not shown).

(Effect of the invention) As mentioned above, this invention is a paving accessory block A.
By enclosing the periphery of the basic block B and laying it on the road surface by fitting the paving accessory blocks A together unevenly, it is possible to easily and quickly form a sturdy and beautiful paved surface on any terrain. However, since the paving accessory blocks each have two zigzag-shaped parallel side walls located facing each other on both sides that are fitted in a concave and convex manner, the shape resistance between them becomes large, and the upper surface of the blocks No staggered steps occur, and the accessory blocks do not slip out toward the outer periphery of the paved surface.

Furthermore, a part of the paving utility block A is provided with projections or long protrusions on its upper surface, thereby forming a guideway for blind people, so that blind people can be guided safely through the road. be.

Furthermore, the surface of the blocks can be easily colored and a colorful paved surface can be formed, and an extremely durable and semi-permanent paved surface can be constructed.

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.
