Description

Specification

Road block technology

The present invention relates to a road surface block having a plurality of protrusions on the surface, and is used not only on sidewalks and roads, but also on indoor floor surfaces and transportation home floor surfaces. It is especially suitable for visually impaired people's guidance blocks for safely guiding visually impaired people, but not limited to this, it is used for guiding road blocks to prevent pedestrians and carts from slipping and falling. It can be used as a sign. Background art

A block for guiding the visually impaired, a type of road block, is laid on roads, public facilities, stations, etc. to assist the visually impaired in moving indoors and outdoors.

Conventionally, as a concrete block for visually impaired persons, for example, a square or rectangular flat block with a side of about 300 mm and a thickness of about 60 mm is recognized on the sole of the foot. In consideration of the fact that there is little risk of tripping, it is common to have multiple protrusions with a flat top of about 5 mm in height. Also, in order to make it easier for low-sighted people to visually recognize, blocks of conspicuous colors such as yellow are usually used.

Conventionally, the most common forms of protrusions are point-like protrusions and line-like protrusions. Of these, point-like protrusions, for example, are protrusions for indicating a position to call attention. It is used to notify the necessity of changing the walking direction.

The linear protrusion is used, for example, to indicate the moving direction, and in this case, the longitudinal direction of the linear protrusion indicates the moving direction.

A block for guiding the visually impaired is formed by using the block having the point-like protrusions and the block having the line-like protrusions in combination according to the application location.

The block material can be concrete, synthetic resin, ceramic, hard rubber, or a combination of these. There are those with synthetic rubber attached, and those with dotted or linear protrusions as separate materials that can be attached later.

In addition, the shape of the point-like protrusions has been conventionally available in various diameters and heights, and there are also arrangement patterns in parallel arrangement and staggered arrangement, but these are not easy to recognize and dangerous for visually impaired people. It is necessary to decide considering the avoidance of sex.

Examples of prior patent applications relating to such visually impaired person guidance blocks include, for example, Japan published patent publication 2001-355213, Japan published patent publication 2002-166410, Japan published patent publication 2003-239230, and the like. . Japanese Patent Publication No. 2001-355213 describes a block for guiding the visually impaired by making the hue, saturation, brightness, etc. of the protrusions different from other parts so that the visually impaired can recognize. The method is described in the block and its manufacture. Japanese Patent Publication No. 2002-166410 describes an electronic device in which information readable by a reader / writer device attached to a cane or the like is stored between a colored concrete layer on the front side and a concrete layer on the back side. It describes how to make a visually impaired person's guide with embedded evening gown.

Japanese Patent Publication No. 2003-239230 describes that a plurality of blocks for guiding visually handicapped persons are connected, and a protrusion for preventing rattling is provided on the back side of the block.

The present invention focuses on the fact that such a visually impaired person guidance block is usually used in a combination of two or more types, and that protrusions on the surface are indispensable. In this way, the manufacturing cost is reduced, the construction 'inventory management is facilitated, and the quality of the block alone and in the block laying state is improved. Disclosure of the invention

The road surface block according to the present invention is a road surface laying block in which a plurality of protrusions are provided on the surface of a flat plate-like block, and a plurality of protrusions are provided in different shapes or arrangement patterns on the front and back surfaces of the block, respectively. Each of these is characterized by a reversible block that can be used as the upper surface of the road surface. The size of the road surface block, the number of protrusions, and the shape are not particularly limited, but for example, when used as a block for guiding the visually impaired, the size, the shape of the protrusion, and the arrangement may be used. There is no particular difference from the conventional one. One of the reasons why the protrusions are provided in different shapes or arrangement patterns on the front and back sides of the block is to make it a reversible block that can be used on either the front or back side, for example when two types of block blocks are required 1 This is because the number of block types can be reduced. It should be noted that the front and back of the block in the present invention is a relative one which may be either front, and the other when viewed as one front may be considered the other.

If the number of types of blocks is reduced, the types of molds will be reduced accordingly, making it possible to reduce the cost of manufacturing equipment and facilitate mass production. In addition, since one block doubles as two types of conventional blocks, inventory management and handling at the construction site are simplified, and these costs are reduced.

Another reason is to use the protrusion on the side that does not appear in the table during use to ensure the stability of the block during construction and after installation.

Conventional road surface blocks are often plate-like on the back side for ease of manufacturing, but when actually installing the blocks, gravel and crushed stones are laid on the road floor, and then When a sand layer for cushioning is laid, or concrete or mortar is placed on the road floor, road blocks are laid on top of it, and jointing materials are filled.

For this reason, in order to stabilize the road surface block, a projection for preventing rattling is provided as in the invention described in Japanese Patent Publication No. 2 0 0 3-2 3 9 2 3 0 described above, or For example, sand or gravel is pasted on the back of Plock with an adhesive.

On the other hand, in the present invention, of the front and back surfaces of the block, the protrusions on the lower side during laying can be used for stability during block construction and after laying, and the protrusion shape or arrangement pattern is different on the front and back sides. In addition to the reversible effect, there is an advantage that the protrusion can be used to secure the stability of the block.

In addition, if grooves are formed in advance on the outer peripheral surface of the block, ,

4 Adhesion can be improved. In addition, since there is a groove on the outer periphery of the block, the groove can be gripped when carrying the block or when adjusting the position when laying, making handling easier.

The material of the block is concrete, synthetic resin, ceramic, and others, but is not particularly limited. From the standpoint of commercialization, quality, and ease of handling, polymer concrete or polymer mortar is preferable.

Polymer concrete and polymer mortar are more expensive than concrete and mortar as materials, but they can provide high strength at an early stage, adhesion, water tightness, freeze-thaw resistance, chemical resistance, wear resistance, There are advantages such as excellent electrical insulation. In addition, blocks can be made thinner and lighter than concrete and mortar blocks, and there is less aggregate separation, so it is possible to manufacture products with excellent homogeneous quality. Since it can be manufactured by vertical striking, it is easy to manufacture.

In the case of polymer concrete and polymer mortar, non-slip processing is possible on the surface of the block to be manufactured by processing the surface of the faceplate of the production formwork. This saves time and improves quality.

When the road surface block according to the present invention is used as a block for guiding a visually impaired person in particular, a plurality of projections for alerting or direction indication that can be sensed by a sole or a cane when a visually impaired person walks. Are provided in different shapes or arrangement patterns on the front and back surfaces of the flat block.

The specific shape and arrangement of the protrusions provided on the front and back surfaces of the block are not particularly limited. However, the most commonly used protrusion shapes and arrangement patterns have been conventionally used as a visually impaired block. It is thought that there is a great demand in that the point projections and linear projections that are formed on the front and back can be used immediately. These blocks for guiding the visually impaired are placed on the road surface (including floors in buildings) so that the front side is partly up and the rest is upside down. By doing so, a sign for guiding the visually impaired is formed.

Since the road surface block of the present invention has protrusions on both the front and back surfaces of the block, For example, in the case of concrete or mortar, it is difficult to manufacture in a normal horizontal state. On the other hand, as the formwork, a formwork provided with recesses corresponding to a plurality of protrusions having different shapes or arrangement patterns on the inner surfaces of the front side plate and the back side plate is used. The face plate is installed vertically across the thickness of the block to be manufactured, and the space between the front side mold member and the back side mold member is filled with curable fillers such as concrete and mortar from above. A method of demolding after curing can be considered. However, in the case of concrete and mortar, there are problems of filling in a narrow space and separation of aggregates when placed vertically, whereas in the case of polymer concrete or polymer mortar, these problems are extremely high. A thin, high-quality reversible block can be manufactured.

The shape of the recesses on the front side plate and the back side plate is arbitrary depending on the application. However, in manufacturing the block for guiding the visually impaired, for example, a plurality of point-like protrusions are provided on one of the front side plate and the back side plate. When the concave portions for forming are dispersedly arranged and the concave portions for forming a plurality of linear protrusions are arranged in parallel on the other side, the configuration is obtained.

Further, as described above, non-slip processing can be applied to the manufactured block by surface treatment such as forming fine irregularities on the surface of the front side plate and the back side plate. Brief Description of Drawings

1 to 6 show an embodiment in which the present invention is applied to a visually impaired person guidance block as the best embodiment.

The most common dimensions include a square with a side of 300 mm and a thickness of 30 to 40 mm for ease of handling, but there is no particular limitation. Different types of dimensions can be used separately or in combination. Fig. 1 shows the surface of block 1, and the top has a flat 5 mm frusto-conical point-like projection 2 that is formed vertically and horizontally, each with 25 pieces in total. Of course, the shape and number of these point-like protrusions 2 are not particularly limited, but may be in accordance with the standard under standardized conditions.

Fig. 3 shows the back side of block 1, with four flat pyramid-shaped linear projections 3 extending in one direction, with a flat top at 5 mm in height, formed in parallel in one direction. ing. The shape and number of these linear protrusions 3 are not particularly limited, but may be in accordance with the standard under standardized conditions.

For example, in Japan, as for the block for guiding the visually impaired, as shown in the figure, the dotted protrusions 2 are used to indicate the position where the attention is drawn. It is used to foresee the need for change, and the linear protrusion 3 is used to indicate the direction of movement.

Then, by using the block having the dot-like projections and the block having the linear projections in combination according to the application location, a visually impaired person guidance sign as shown in FIG. 7 is formed.

In the illustrated example, the groove 4 is formed on the outer peripheral surface of the block 1 as shown in FIGS. This groove 4 has a function of increasing the adhesion to the block 1 by allowing the joint material when laid on the road surface to enter. In addition, when carrying block 1 or adjusting the position, or when removing block 1 laid as necessary, you can place your fingers on this groove 4 part or hook a tool, etc. The handling of 1 becomes easy. ^ Block 1 is preferably made of polymer concrete, and is colored yellow with pigments and toner. In the case of polymer concrete, the dispersibility of pigments and toners is better than that of concrete, so it is easier to develop colors than concrete, and colors suitable for recognition by low-sighted persons can be easily realized.

An example of blending polymer concrete is as follows.

Unsaturated polyester resin: 13.0% by weight

Fine aggregate (sand): 41.0% by weight

Coarse aggregate (gravel): 32.0% by weight

Calcium carbonate: 14.0% by weight

In addition to these, a curing agent (about 1.0% by weight based on the unsaturated polyester resin), titanium (about 3.0% by weight based on the unsaturated polyester resin), a pigment, and the like are mixed.

7 and 8 show examples of laying signs for visually impaired persons using the block according to the present invention, respectively.

Reversible Plock 1 has point-like protrusions 2 formed on one side and line-like protrusions 3 on the opposite side. These are shown in FIG. 7 and FIG. 8 as an example. Lay them side by side. The linear protrusion 3 indicates the moving direction, and the dotted protrusion 2 is used for a position to call attention.

In the example of Fig. 7, a visually impaired person who has been guided to the linear protrusion 3 of the braille block 1 from above in the figure detects the braille protrusion 2 with the tip of the cane or the sole of the foot, and there is a roadway ahead. Is to make it possible to recognize the existence of stairs.

In the example of Fig. 8, for example, a visually handicapped person who has been guided to the linear protrusion 3 of the Braille block 1 from the left in the figure detects the Braille protrusion 2 with the tip of the cane or the sole of the foot, and This is to make it possible to recognize that it is an intersection.

FIG. 9 is a diagram schematically showing the principle of the method for manufacturing a road surface block according to the present invention, in which a manufacturing form 11 is placed vertically and filled with uncured polymer concrete having a predetermined composition from above. To do.

In the illustrated example, the formwork 11 has a dot-like shape for forming the point-like protrusion 2 on the inner surface [the surface side plate 12 having the HI portion 1 2 a and the line-like protrusion 3 for forming the inner surface. Linear concave And a back side plate 1 3 having a portion 1 3 a. In addition, a bottom portion 1 2 b for forming one of the four outer surfaces of the manufactured block 1 is provided in the lower portion of the front side plate 1 2, and the front side plate 12 and the rear side plate With the 3 facing each other, the sides are closed, and a rod-shaped side plate 14 that forms one of the four outer surfaces of the block 1 is attached.

When the polymer concrete filled in the mold 11 is cured, in the example shown in the figure, the back side plate 13 and the side plate 14 are first removed to expose the surface having the linear protrusions 3. Next, by removing the hardened block 1 from the front side plate 12, the manufacturing procedure for one block 1 is completed.

Various modifications can be made to the shape, combination, and manufacturing procedure of the members such as the face plate that make up the formwork. In order to facilitate understanding, the procedure for manufacturing one block has been explained. Actually, however, a mass production formwork made up of a large number of vertically placed formwork was used, and a large number of blocks 1 were simultaneously used. It is desirable to be able to manufacture. Industrial applicability

The road surface block of the present invention can be used by laying on outdoor sidewalks, roads, indoor floors, transportation floors, etc., especially for visually impaired people to safely guide visually impaired people. Suitable for use as a person guidance block. Further, according to the present invention, such a block can be manufactured easily and inexpensively, and a high-quality road surface block can be obtained.
