    Method of manufacturing boundary block for light reflection {Method of boundary block reflecting light}
    The present invention relates to a method for manufacturing a boundary block used between a sidewalk and a roadway, and more particularly, to reflect light on a shape display for recognizing the shape of a road on its outer surface formed of porous concrete. The present invention relates to a manufacturing method of a boundary block for reflecting light, which is made of a material and sprays a water-soluble acrylic resin on the inside to penetrate the inside thereof to prevent traffic accidents caused by night driving and to improve durability.
    Conventional road boundary stones are classified according to their materials, and are generally classified into stone boundary blocks that are used by cutting a stone having a rectangular cross section to a certain length, concrete boundary blocks cured with cement, and plastic boundary blocks molded from plastic. do.
    Among the road boundary stones as described above, the stone boundary block has high strength and durability, but since the light is not reflected, the driver may not be aware of the shape of the road when driving the vehicle at night.
    The concrete boundary block is weak in strength due to its weakness, and in particular, the surface of the concrete is easily collapsed due to weak smoke of the vehicle. Also, like the stone boundary block, the surface is discolored when used for a long time without reflecting light. It hurts the beauty of the city center.
    The plastic boundary block has the advantage that it can be manufactured in a variety of colors, but like the concrete boundary block, there is a problem in that it is weak in impact and has no durability and no light is reflected at night.
    In order to solve this problem, a method of forming a hole in the boundary stone and installing a reflector reflecting light in the hole, a method of simply attaching a luminous tape to the surface of the boundary stone or boundary block, and a constant surface of the boundary stone or boundary block A method of digging grooves and attaching a luminous tape to the grooves has been proposed.
    In the method of simply attaching the luminous tape to the surface of the boundary stone, the luminous tape is more prominent than the surface of the boundary stone and is attached only by the adhesive force, so it is easy to fall under external influences (wheels or rainwater of the vehicle), thereby ensuring durability. There is no problem.
    The method of attaching the reflector or the luminous tape to the groove or hole of another boundary stone is difficult to process the hole or the groove, resulting in an increase in working time and labor costs, which is not practical.
    An object of the present invention has been researched and developed to solve all the problems and problems of the prior art as described above, to form a groove of a certain shape, which is a road-shaped mark on the outer surface of the porous concrete to fill the groove with a light reflecting material By spraying the water-soluble acrylic resin throughout the surface of the boundary block, the surface hardness is high and the durability is excellent, and it is possible to manufacture in various colors, and the light reflection of the vehicle's light at night is excellent. It is possible to clarify the classification, and therefore, to provide a method of manufacturing a boundary block to prevent traffic accidents and to obtain an inexpensive boundary block.

    It will be described below on the basis of the accompanying drawings showing the mold and the pressure plate used to manufacture the boundary block according to the present invention.
    As shown in the figure, the mold 12 is formed on the flat pedestal 10, the upper and lower ends are open and have a long shape, and the upper and lower sides of the mold 12 are inserted into the inner space of the mold 12. It consists of the pressing plates 14a and 14b which are bent in a cross-sectional shape and the corner part of the inner surface is rounded.
    The pressure plate 14a, 14b has a smooth bottom surface, as shown in FIG. 1, and a shape protrusion 141 that can recognize a shape of a road, that is, a straight line, a curved line, a median separator, and the like, as shown in FIG. There is.
    The method of manufacturing the boundary block of the present invention using the apparatus of the present invention as described above will be described in detail.
    The first step is to mix the aggregate, cement, water, water-reducing agent, etc. according to the mixing ratio of the conventional porous concrete using aggregates of less than 19mm and stone dust to form the first boundary block 20a as an intermediate molded article. to be.
    Specifically, the aggregate and stone powder sand 1500 ~ 2200kg or less, cement 250 ~ 400kg per 1m 3, water is used in the water-cement ratio within the range of 30 to 15%, one of the admixtures Phosphorus water-sensitive dispersant is added within the range of 2% by weight of the amount of cement used and uniformly mixed with a mixer.
    The mixed mixture is put in a predetermined amount from the top of the mold 12 placed on the pedestal 10 and covered with a pressure plate 14a, and then pressure-molded while vibrating according to a conventional method. In this case, spaces corresponding to the thickness of the pressure plate 14a are formed on the top and one surface of the first boundary block 20a.
    The porosity of the porous concrete shaped as the first boundary block 20a by pressure molding should be maintained at 5 to 30% because of infiltration of acrylic resin, epoxy resin, urethane resin, and the like. To ensure that
    The second process is a process of forming the second boundary block 20b by mixing the fine-grained concrete on the top and one surface of the first boundary block 20a formed in the above process and injecting and molding the porous concrete on the electric process. to be.
    In this process, 1400-2200 kg of aggregate containing at least one of silica sand, soybean gravel, crushed glass, jade, ganban stone and feldspar less than 6 mm per m 3 is prepared, and cement is white cement, usually portland cement, 250-450 kg of cements, such as crude steel cement and super-steel cement, are prepared.
    Water and admixture are mixed with the aggregate and cement prepared in this way, and water is used within 15 to 35% of water-cement basis. The admixture uses a water soluble dispersant, a high performance water soluble dispersant, and a high fluidizing agent. Use within 4% of cement usage.
    If necessary, pigments can be used. The pigments use inorganic pigments, and the amount used should be within 10% by weight of the amount of cement used.
    The mixture obtained by mixing in such a manner is sprayed on the top and one surface of the first boundary block 20a formed by the first process in a uniform thickness, covered with a pressure plate 14b, and then vibrated according to a conventional method. Pressure molding is carried out. At this time, the groove 201 by the shape protrusion 141 of the pressure plate 14b, as well as the space corresponding to the thickness of the pressure plate 14b is formed on the top and one surface formed in the shape of the second boundary block 20b. Will be created.
    In order to derive the aesthetics of the boundary block having the natural stone color after the molding, the mold 20b and the pressure plate 14b are disassembled, and after spraying water on the surface with a large amount of water, the surface does not collapse. The surface of the stone should be exposed and its watering quantity should be 2kg per 1㎡. The porosity of the boundary block thus manufactured should also be maintained within the range of 5 to 30%.
    In the third process, the second boundary block 20b, which is an intermediate molded article formed in the electrical process, is separated from the mold 12 and the pressure plate 14b, and then moved to the curing chamber, and then about 60 ° C. according to a conventional curing method. Steam or dry curing for more than 10 hours. After completion of the primary curing in this way, and dried in a dry state, the grooves 201 formed by the shape projections 141 of the pressure plate 14b using at least one or more of 3 mm or less of crushed glass, silica sand, sand The light reflecting material 202 is added to 1% by weight of 0.05 to 0.2% by weight of epoxy, pearl pearl, pigment, luminous, photoluminescent, and fluorescence to add 20% or less of epoxy. The resin may be epoxy, water-soluble acrylic, urethane resin or unsaturated resin.
    The groove 201 may be attached with a luminous tape (not shown) having a shape corresponding to that of the groove 201.
    The fourth step is a step of forming the resin layer 204 on the top and one surface of the second boundary block 20b, the intermediate molded article cured in the electrical process, to improve durability.
    At least one or more of pearl pearls, pigments, luminous, photoluminescence, and fluorescence is added and mixed in an amount of 0.05 to 0.2% by weight based on the amount of epoxy used in 1% by weight of a resin such as transparent epoxy or epoxy.
    The mixed mixture is sprayed with a brush or spray 203 or less than 2 kg per m 2 and then cured to obtain a boundary block of the finished product.
    If necessary, after obtaining the concrete boundary block of the finished product, after about 24 hours, spray the water-soluble acrylic resin to the inside of the boundary block again to the surface of the boundary block to obtain a durable concrete boundary block.
    When the resin is sprayed on the boundary block, which is a molded article, in order to proceed with this process in the manufacturing plant, there is a problem such as an increase in the cost due to the complexity of the process and the economic burden of providing the necessary facilities and drying rooms. It is also a desirable construction method to spray the resin in large quantities using a spray after the installation of the product.
    The concrete boundary block of the present invention is superior in strength, durability and water permeability even when used in the state of not spraying the resin compared with the conventional concrete boundary block.
