Description

  The present invention relates to a visually impaired person guiding block and a method for laying a visually impaired person guiding block. More specifically, the present invention is a visually impaired person guidance block made of various materials, and has an anchor projecting on the bottom surface. The present invention relates to a visually handicapped person guiding block having improved stability, durability, followability to a road surface shape, and the like, and a method of laying the visually handicapped person guiding block.

  Here, the definition or usage of terms will be explained. Regarding the so-called “block for guiding the visually impaired”, JIST 9251 (2001) established “the shape / dimensions and the arrangement of the projections of the block for guiding the visually impaired”. Furthermore, JIST 9251 (2014) established “Elderly and handicapped design guidelines—shapes and dimensions of protrusions such as visually impaired guidance blocks and their arrangements”. In the JIS, the shape and size of the block itself, the shape and size of the protrusions protruding from the block, and the arrangement thereof are defined. However, there is no provision regarding the material of the block, etc., and conventionally, a metal plate, a metal rod, a concrete plate each having a plurality of dot-like projections, linear projections, parallel projections, and half-dome-shaped projections on the surface. Block or porcelain or ceramic tile, natural / synthetic rubber, thermoplastic synthetic resin, thermosetting synthetic resin, thermoplastic elastomer, plate or sheet made of natural / synthetic rubber and thermoplastic synthetic resin, etc. Has been used in various names such as Braille blocks, Braille tiles, walking derivatives, guidance markers, guide rods, etc., for guiding visually impaired people. All of these similar terms used from are intended to be included.

  In addition, regarding the shape / dimension of the block, the shape / dimension of the protrusion protruding from the block, the arrangement thereof, etc., the present invention does not necessarily strictly comply with the above-mentioned JIS regulations.・ Include changes.

  The term “anchor” used in the present invention is a so-called “fastener” for fixing a visually impaired person guiding block having a plurality of protrusions formed on the surface thereof to a road surface or the like. Accordingly, the material and shape of the anchor used in the present invention is not particularly limited as long as it has a function of fixing the visually impaired person guiding block to the road surface or the like. That is, it is selected from a wide range of materials such as metal, natural or synthetic rubber, thermoplastic resin, thermosetting resin. Also, the shape is arbitrarily selected, such as straight, one having a different diameter portion to improve the anchoring effect, one having an L-shaped tip or a hook shape, tapered, or reverse tapered. Further, the visually impaired person guide block and the anchor can be connected by a method of connecting the visually impaired person guide block and the anchor by integral molding, or by embedding a nut in a predetermined place on the back of the visually impaired person guide block, A method of forming a screw at the tip of the anchor and screwing and connecting the two is arbitrarily selected.

  By the way, there are merits and demerits in the construction methods for laying blocks for guiding visually impaired persons on the road surface. For example, a concrete block, porcelain or earthenware tile is formed with a concave portion at least as thick as the concrete block, porcelain or earthenware tile on the road surface to be laid. After the adhesive is put, a method is adopted in which a concrete block, porcelain or earthen tile is dropped and joined and fixed. These construction methods have many construction procedures, large construction steps, and high construction costs. In addition, when a part of a concrete block, porcelain or ceramic tile is lost due to aging, a large amount of labor and cost are required for the renewal work.

  On the other hand, plates or sheets made of natural / synthetic rubber, thermoplastic synthetic resin, thermosetting synthetic resin, thermoplastic elastomer, mixture of natural / synthetic rubber and thermoplastic synthetic resin, etc. are visually impaired for both indoor and outdoor use. It is used as a person guidance block (hereinafter referred to as “rubber / resin Braille block”). The rubber / resin Braille block is shipped from the factory in a state where an adhesive such as butyl or epoxy resin is applied to the back surface and protected with a release paper. The basic construction method when these blocks are attached and laid on the road surface is as follows. (1) Assign and inking (including the outer periphery) to the base surface to which the block is attached. → (2) After the ink is drawn out, clean the ground surface and thoroughly remove dust, dust, moisture and oil on the surface. (It is more effective if it is sanded and cleaned with a blower). → (3) After cleaning, stir the dedicated primer and apply evenly with a roller brush. (It is recommended to apply a masking tape to prevent the primer from sticking out). → (4) After application, the primer agent is sufficiently dried and cured. → (5) After drying, remove the release paper on the back of the rubber / resin Braille block and stick the block so that air does not enter between the block and the substrate. → (6) After sticking, roll the entire surface with a rubber hammer. (Especially on the four edges) Rubber / resin braille blocks require a large number of preparation steps until they are attached to the road surface. Cannot be laid in rainy weather or when the humidity is high. Depending on the type, there are drawbacks such as requiring a predetermined period of curing after sticking. In other words, it depends on the material and condition of the road surface, the weather and the like. The biggest drawback is that the construction time is longer and sometimes it is necessary to block the traffic for a long time compared to the mechanical joining method using rivets, bolts, etc. Performance may deteriorate and may peel off.

  Therefore, visually impaired people who have improved workability, stability after installation, durability, followability to the shape of the road surface, etc., compared to the blocks for guiding visually impaired people, which are made of various materials. A method for laying a guiding block and the visually impaired person guiding block has been desired in this field.

Therefore, the invention described in Patent Document 1 is easier to construct, more stable after laying, more durable, and better on the road surface, compared to the sticking laying type guidance block for visually impaired persons manufactured with the above-mentioned various materials. It does not suggest a visually impaired person guiding block with improved followability and a method for laying the visually impaired person guiding block.

Patent Document 2 is a Braille font that is used by being embedded in a road pavement for guiding and assisting a visually impaired person, and is exposed from a leg embedded in the road pavement and the road pavement. A braille bag is described in which a metal head composed of a head to be stepped on is integrated with rubber, thermoplastic synthetic resin, or the like. (wrap up)
The problem to be solved by the idea described in Patent Document 1 is that the conventional Braille heels solve the soft feeling of walking, safety such as slip resistance, and durability as a road pavement. (0005). Therefore, the idea described in Patent Document 2 is more workable, stable after laying, durability, and shape of the road surface than the sticking laying type guidance block for the visually impaired manufactured by the various materials. It does not suggest a visually impaired person guiding block with improved followability and a method for laying the visually impaired person guiding block.

  Patent Documents 3 to 17 are related to the visually impaired person guidance block in some respects, but all have a workability compared to the sticking laying type visually impaired person guidance block manufactured from the various materials described above. It does not suggest a visually impaired person guiding block with improved stability, durability, followability to the shape of the road surface, and the like, and a method for laying the visually impaired person guiding block.

[Explanation about anchors]
1. Anchor material, etc. The “anchor” used in the present invention is a so-called “fastener” for fixing a visually impaired person guiding block having a plurality of protrusions formed on the surface thereof to a road surface or the like. Accordingly, the material and shape of the anchor used in the present invention is not particularly limited as long as it has a function of fixing the visually impaired person guiding block to the road surface or the like. That is, it is selected from a wide range of materials such as metal, natural or synthetic rubber, thermoplastic resin, thermosetting resin. Also, the shape is arbitrarily selected, such as straight, one having a different diameter portion to improve the anchoring effect, one having an L-shaped tip or a hook shape, tapered, or reverse tapered. Further, the visually impaired person guide block and the anchor can be connected by a method of connecting the visually impaired person guide block and the anchor by integral molding, or by embedding a nut in a predetermined place on the back of the visually impaired person guide block, A method of forming a screw at the tip of the anchor and screwing and connecting the two is arbitrarily selected.

2. Formation method of the anchor The method of forming the anchor in the visually impaired person guidance block is a method of integrally forming the visually impaired person guidance block and the anchor, and the visually impaired person guidance block and the anchor are manufactured separately, and then the visually impaired There is a method of adhering a person guide block and an anchor. When the visually impaired person guiding block and the anchor are integrally formed, the visually impaired person guiding block and the anchor are naturally made of the same material. After the visually-impaired person guide block and anchor are manufactured separately, when the visually-impaired person guide block and anchor are fixed, insert nuts are incorporated on the back surface and screws are formed when the block is molded. Screw into the anchor.

3. Anchor diameter / length Anchor diameter depends on the material of the road surface on which the block is constructed, ie asphalt, concrete, terrazzo tile, natural stone floor, artificial marble, etc., or the material of the anchor itself, ie metal, rubber or resin. Different. In the case of metal, a range of 5.0 to 10.0 mm is preferable, and in the case where the anchor and the block are integrally formed, that is, in the case of resin, a range of 7.0 to 15 mm is preferable. The length of the anchor is preferably in the range of 20 to 50 mm for both metal and resin. In any case, the diameter and length of the anchor take into consideration various conditions such as the material of the road surface on which the block is constructed, the anchor material / formation method (integrated molding of the anchor and block or mounting after separate molding), and cost. Must be determined. In particular, when the anchor material is resin, the anchor diameter and length are affected by the rigidity of the material itself, so verification of measurement of Young's modulus (longitudinal elastic modulus) or the like is necessary.

4). As shown in the attached drawings, various patterns can be considered as the places where the anchors are formed. However, if the anchor is formed by integral molding on the base portion of the block, that is, the portion where the protrusion is not formed (thus, the thin portion not including the thickness of the protrusion), sink marks or the like may occur during molding. There is. Therefore, the anchor is preferably formed immediately below the protrusion. In addition, when a block is formed, when an insert nut is incorporated on the back surface and an anchor is attached later, it is preferable to embed the nut directly below the protrusion because of the thickness. In addition, when a nut is embedded directly under a flat surface (four corners) where there are no protrusions on the block body, the thickness of the flat surface where there are no protrusions can withstand the shear stress and impact of walking due to the embedded nut. is important. Therefore, when a nut is embedded directly under a flat surface portion (four corners) where no protrusions are formed on the block main body, the thickness of the flat surface portion without protrusions is preferably at least 3 mm, preferably in the range of 3 to 5 mm.

[Manufacturing method of guiding block for visually impaired with anchor]
The visually impaired person guiding block with an anchor according to the present invention is manufactured integrally with an anchor and a block main body on which a protrusion is formed by a press molding method or an injection molding method. In this case, the position where the anchor protrudes is preferably directly below the protruding portion protruding from the surface, but may be formed directly below the corner, preferably below the corner, if necessary. . Alternatively, the visually impaired person guide block with anchor according to the present invention is manufactured in a separate process by embedding a nut in a predetermined portion of the back surface (surface laid on the road surface) of the block body. It is manufactured by screwing with a resin or metal anchor. In this case as well, the location where the anchor is projected is preferably directly below the protruding portion protruding from the surface, but if necessary, it may be formed on a flat portion where no protrusion is formed, preferably directly below the corner. Good.

  In order to integrally mold the visually impaired person guide block with an anchor according to the present invention by a press molding method or an injection molding method, a design die having a cavity for forming a projection, and a projection base die And a press mold or an injection mold composed of a planar main body base mold in which a cavity for forming an anchor is formed. Next, the design mold, the protrusion base mold, and the planar main body base mold in which a cavity for forming an anchor is brought into close contact with each other to form a protrusion. The tee is formed, and the compound having a predetermined composition is filled in the cavity for forming the protrusion, heated at a predetermined temperature and cured to form the protrusion, and then the protrusion base metal The mold is removed, the flat body part base mold in which the cavity for forming the anchor is drilled is brought into close contact with the design mold, and the cavity for forming the planar body part and the anchor is formed. Fill the cavity for forming the main body part and the anchor with the compound with the predetermined composition, heat and cure at the predetermined temperature, and bond the projecting part, the planar main body part and the anchor respectively. To unite It is manufactured me.

In order to attach the anchor to the block main body after the anchor and the block main body with projections are manufactured separately from each other, the anchor guiding block according to the present invention is the same as that used in the integral molding. In addition, a design mold in which a cavity for forming a protrusion is formed, a protrusion base mold, and a planar main body base mold are used. At that time, a metal or resin nut is placed in a predetermined position of the cavity of the planar main body base mold so as to be embedded in the resin, and the design mold, the protrusion base mold, The main body base molds are brought into close contact with each other to form a cavity for forming the protrusion, and the compound having a predetermined composition is filled into the cavity for forming the protrusion, A mold for forming a planar body part by heating and curing at a temperature to form a projection part, and then removing the projecting part base mold and bringing the planar body part base mold and the design mold into close contact with each other. A cavity for forming a tee and forming a planar main body is filled with a compound having a predetermined composition, and is heated and cured at a predetermined temperature to be a plane in which a protrusion and the nut are embedded. Gluing the main body parts together Thus it is produced. Thereafter, an anchor bolt and a nut manufactured in a process different from the above process are screwed together to form a visually impaired person guidance block with an anchor.
If there are too many anchors, it takes a lot of work, and if there are too few anchors, a problem occurs in the fixing strength. Accordingly, 5 to 9 and at least 5 are preferable.

  The basic construction procedure for the visually impaired person guiding block with anchor according to the present invention is assigned to the ground surface on which the visually impaired person guiding block with anchor is laid. Next, inking (only the center position) is performed. Next, using an appropriate jig, a hole for embedding the anchor is drilled. Adhesive is injected into the hole, the anchor is inserted into the hole, and the position is finely adjusted. Cured for a predetermined period and completed. Since the jig is used to determine the position of the hole in which the anchor is embedded, a jig or the like is sufficient. The adhesive may be an epoxy, urethane, acrylic or other conventional one.
