Moreover, the vehicle stop of this invention is provided with the said pillar, and the said main body is hold | maintained at the holding member fixed to the ground. That is, the present invention uses a fiber reinforced plastic having both light transmittance and strength for the main body of the column, and transmits the light of the light emitting body provided inside the column to the outside.

  Hereinafter, the column body and the car stopper of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
The vehicle stopper 100 according to the first embodiment includes a column body 3, a holding member 2 that holds the lower portion of the column body 3 and is fixed to the ground, a lid 4 that closes the upper portion of the column body 3, the column body 3 and the holding body. The base cover 5 is provided on the outer peripheral surface of the column 3 so as to cover the boundary of the member 2, and the chain hook 6 attached above the column 3.

  The column 3 includes a hollow columnar main body 31 formed of fiber reinforced plastic (hereinafter referred to as FRP), and a light emitter (hereinafter referred to as a lighting fixture) 32 installed inside the main body 31. FIG. 1 is a cross-sectional view of a car stopper 100 according to the first embodiment.

As shown in FIG. 1, the main body 31 is a cylindrical hollow body. L. It is provided so as to be perpendicular to. A pair of chain hook screw holes 31 a for fixing the chain hook 6 is formed above the main body 31, and a connecting bolt for fixing the main body 31 itself to the holding member 2 below the main body 31. A pair of through holes 31b are formed.

  The FRP that forms the main body 31 is mainly composed of a base material and a reinforcing material that reinforces the base material.

  The base material of FRP is not particularly limited. For example, epoxy resin, vinyl chloride resin, vinyl acetate resin, polystyrene, ABS resin, acrylic resin, polyethylene, polypropylene, fluororesin, polyamide resin, acetal resin, polycarbonate, fiber base Thermosetting resins such as thermoplastic resins such as plastic, phenol resins, urea resins, melamine resins, unsaturated polyester resins, diallyl phthalate resins, polyurethane resins, silicon resins, and polyimide resins can be used. In this embodiment, an epoxy resin is used because it has excellent heat resistance, alkali resistance (cement alkali), chemical resistance, and mechanical properties.

  The material for the reinforcing material of FRP is not particularly limited. For example, glass fiber, carbon fiber, aramid fiber, cotton fiber, hemp fiber, silk fiber, wool, jute, vinylon fiber, nylon fiber, tetron fiber, rayon fiber, Examples thereof include boron fiber, Tyranno fiber, stainless steel fiber, and a mixture containing at least one selected from these groups. In the present embodiment, glass fiber is used as a reinforcing material because it is excellent in light transmittance. The color of the reinforcing material is not particularly limited. For example, a colored yarn dyed with the above-mentioned fibers, a fluorescent fiber dyed with the above-mentioned fibers in a fluorescent color, a phosphorescent fiber dyed with the above-mentioned fibers with a phosphorescent paint, etc. Can also be used. Furthermore, the state of the reinforcing material is not particularly limited. For example, the reinforcing fiber can be used by twisting the above-described fiber, or using the above-mentioned fiber in a braided shape.

  Further, in addition to the base material and the reinforcing material, the FRP may appropriately contain a reinforcing material and a filler.

  Although it does not specifically limit as a reinforcing material, For example, a glass bead, glass flakes, glass powder, milled glass, glass frit, a silica etc. can be used.

  Although it does not specifically limit as a filler, For example, whiskers, such as fillers, such as aluminum hydroxide, calcium carbonate, titanium oxide, and mica, potassium titanate whisker, barium titanate whisker, etc. can be used.

  The FRP molding method is not particularly limited, but, for example, hand stacking method, spray-up method, matched die method, premix method, prepreg method, rolling table method, sheet winding method, tape winding method, filament winding method, pultrusion molding Method, injection molding method, extrusion molding method and the like can be used. In the present embodiment, by using continuous long glass fiber as the reinforcing material, a molded article having extremely high strength can be obtained, and the strength characteristics can be freely designed as desired. Since a plurality of outer diameters can be set in the hollow hollow molded body, it is molded using a filament winding method. Here, the filament winding method is a method of forming a reinforced plastic that is formed by infiltrating a resin into a bundle of many filaments and winding this around a core mold. In the present embodiment, when the main body 31 is formed using the filament winding method, three layers of an innermost layer, an intermediate layer, and an outermost layer are formed. These three layers have different winding angles when winding a bundle of filaments impregnated with resin around a core mold, that is, fiber orientation angles.

  The fiber orientation angle of the innermost layer is preferably 80 to 89 ° with respect to the core axis. By making the fiber orientation angle of the innermost layer in this way, the circumferential direction of the main body 31 is strengthened, and the strength of the main body 31 can be improved. Further, by setting the fiber orientation angle of the innermost layer in this way, expansion and contraction in the radial direction due to a temperature change of the main body 31 can be prevented. Moreover, it can prevent that a crack generate | occur | produces in a molded object.

  The fiber orientation angle of the intermediate layer is preferably 0 to 40 ° with respect to the core axis. When the fiber orientation angle of the intermediate layer exceeds 40 °, the bending strength of the molded product tends to decrease.

  In other words, since the bending strength increases as the fiber orientation angle is reduced to 40 ° or less, in the above example, the intermediate layer ensures the bending strength required for the vehicle stop.

  The fiber orientation angle of the outermost layer is preferably 80 to 89 ° with respect to the core axis. By setting the fiber orientation angle of the outermost layer in this way, the circumferential direction of the main body 31 is strengthened, and the strength of the main body 31 can be improved. Further, by setting the fiber orientation angle of the outermost layer in this way, expansion and contraction in the radial direction due to temperature change of the main body 31 can be prevented. Furthermore, by setting the fiber orientation angle of the outermost layer in this way, the fibers can be wound uniformly, uniformly and densely, so that the surface of the main body 31 can be finished with less unevenness. In addition, in order to make the surface of the main body 31 finish with less unevenness, a non-woven fabric, cloth-like tape, or sheet using the above-described reinforcing material may be wound around the surface of the outermost layer.

  The fiber orientation angle may be the same orientation angle for the innermost layer, the intermediate layer, and the outermost layer.

The main body 31 formed of such FRP has light transmittance. Furthermore, the specific gravity of the FRP used in the present embodiment is about 1.8 to 2.2 g / cm ³ , and the specific gravity of the steel pipe conventionally used for the car stop is the specific gravity of the FRP used in the present embodiment. About 4 times. Therefore, the weight of the main body 31 is about a quarter of the weight of the steel pipe having the same size as the main body 31 of the present embodiment. Since the main body 31 of the present embodiment is lighter than a steel pipe, the work for transporting the main body 3 can be facilitated, and the cost for transporting can be reduced. The main body 31 has a bending strength equal to or higher than that of a steel pipe. Furthermore, the thermal conductivity of the main body 31 is lower than that of a metal such as steel, and in addition, the specific heat is large. Therefore, even if the main body 31 is installed outdoors, the main body 31 is unlikely to become hot. Furthermore, since the main body 31 has a lower hardness and elastic modulus on the surface of the main body 31 than a metal such as steel, the shock absorption in the elastic deformation region is good (that is, the impact received during a collision is small). Furthermore, even when the main body 31 is impacted and destroyed, the main body 31 is not shattered and scattered. Furthermore, unlike the metal, the main body 31 has acid resistance and therefore does not rust. Furthermore, the main body 31 is excellent in heat resistance.

  The bending strength of the main body 31 is preferably 230 MPa (corresponding to STK-400 defined in JIS G 3444) or more, and more preferably 300 MPa or more. If the bending strength of the main body 31 is less than 230 MPa, the function and performance as a car stopper cannot be obtained.

  It is preferable that the main body 31 has a light transmittance that can improve the visibility of the vehicle stop when the lighting fixture 32 housed in the main body 31 is turned on in a dark place. Specifically, when a lighting fixture that emits light having a wavelength of 400 to 800 μm is used, the light transmittance of the main body 31 is preferably 1% or more, and more preferably 2% or more. If the light transmittance is less than 1%, it tends to be difficult to recognize the light source even in the dark. In the present embodiment, the main body 31 is used which can obtain a light transmittance of 3% or more when a fluorescent lamp that emits light having a wavelength of 570 to 600 μm is used as a lighting fixture. Here, the light transmittance means the ratio of the energy of light transmitted through the boundary surface between two media and the energy of incident light.

  Although it does not specifically limit as the lighting fixture 32, For example, a fluorescent lamp, an incandescent lamp, LED, etc. can be used. In this embodiment, a fluorescent lamp is used because it has a longer life than other lighting fixtures and can be easily replaced. In particular, the lighting fixture 32 is preferably provided with a waterproof function such as providing a cover outside the fluorescent lamp. Moreover, the color of the light radiate | emitted from the lighting fixture 32 is not specifically limited. For example, the appearance of the car stop 100 can be changed by changing the color of light emitted from the lighting fixture 32 by replacing the lighting fixture 32.

Moreover, the transfer film mounting part 23b is a part which mounts the lower end surface of the below-mentioned transfer film.

  In addition, an opening 22 c for leading the wiring of the lighting fixture 32 to the outside of the car stopper 100 is formed in the bottom portion 21. Further, the second upright portion 23 is formed with a hole 23a through which the connecting bolt B for fixing the main body 31 to the holding member 2 is formed. The shaft portion of the connecting bolt B is screwed into the hole 23a. A matching nut is incorporated.

  The receiver 25 is for supporting the lower end of the lighting fixture 32, and is provided integrally with the first upright portion 22. The receiver 25 has a disk shape in which a hole for leading the lower end of the lighting fixture 32 is formed at the center.

  Although it does not specifically limit as a material of the holding member 2, For example, aluminum, iron, bronze, magnesium, antimony, tin, lead etc. can be used. In this embodiment, aluminum is used because it is lightweight and difficult to oxidize.

The lid 4 of the bollard 100, from the top of the pillar 3, is intended to prevent the entering foreign matter inside the pillar 3. As shown in FIG. 2 (a), the lid 4 has integral upper 41 mounted on the upper end of the body 31, and a fitting portion 42 which fits into the inside of the body 31. The fitting portion 42 is formed with a recess 42 a for fixing the upper end of the lighting fixture 32. Moreover, you may fix the lid | cover 4 to the upper part of the main body 31 with an adhesive agent.

  The base cover 5 of the car stopper 100 is for covering the head of the connecting bolt B. As shown in FIG. 2B, the base cover 5 is a boundary between the main body 31 and the holding member 2, and the ground surface G.P. L. It is an annular member provided to surround the outer periphery of the column 3 at a position in contact with. The upper part of the inner peripheral surface of the base cover 5 is in close contact with the outer peripheral surface of the main body 31. Moreover, the inner peripheral surface lower part of the base cover 5 has an inner diameter slightly larger than the outer diameter of the column 3, and a hollow part 5 a is formed. The hollow portion 5 a accommodates the head of the connecting bolt B for fixing the main body 31 to the holding member 2.

  The material of the base cover 5 is not particularly limited, and for example, EPDM can be used.

  The chain hook 6 of the car stopper 100 is used when a plurality of car stoppers 100 are connected by a chain. The chain hook 6 is attached above the column 3. The chain hook 6 is not particularly limited. For example, as shown in FIG. 2A, the hook member 61 is provided on the outer surface of the main body 31 and the fastening plate 62 is provided on the inner surface of the main body 31. Provided so as to abut, the screw 63 is inserted into the screw hole 61b formed in the hook member 61, the chain hook screw hole 31a formed in the main body 31, and the screw hole 62a formed in the fastening plate 62.

Thereby, the vehicle stop 100 and the other vehicle stops 100 are connected via the chain. The material of the chain hook 6 is not particularly limited, but in the present embodiment, aluminum is used because it is lightweight and difficult to oxidize.

  When the car stop 100 of the first embodiment is used at night, the lighting fixture 32 is turned on. When the lighting fixture 32 is turned on, part of the light passes through the main body 31 of the column 3. Even when the same lighting fixture 32 is used, when the light transmittance of the FRP used for the main body 31 is high, the car stopper 100 shines brighter than when the light transmittance of the FRP used for the main body 31 is low. Therefore, a driver or a pedestrian of an automobile can easily recognize the presence of the car stop 100 even at a position away from the car stop 100. Moreover, the light which permeate | transmitted polished glass can also be produced by intentionally using FRP with low light transmittance for the main body 31. FIG. Moreover, the vehicle stop 100 of the present invention can also be used as an outside light for a parking lot or the like.

(Embodiment 2)
The car stopper 110 according to the second embodiment uses FRP that is particularly excellent in light transmittance for the main body 31 of the car stopper 100 according to the first embodiment. Further, between the main body 31 and the lighting fixture 32, A light-transmitting film (hereinafter referred to as transfer film 7) having a pattern on the surface is disposed.

  Regarding the light transmittance of the FRP, it is preferable that the pattern formed on the transfer film 7 accommodated in the main body 31 is visible when the lighting fixture 32 is turned on, and is preferably a substantially transparent FRP. . Specifically, when a lighting fixture that emits light having a wavelength of 400 to 800 μm is used, the light transmittance of the main body 31 is preferably 15% or more, and more preferably 25% or more. If the light transmittance of the main body 31 is less than 15%, there is a tendency that characters, designs and the like applied to the transfer film 7 cannot be clearly seen even if the internal lighting fixture 32 is turned on. In particular, when the light transmittance is less than 3%, characters and patterns applied to the transfer film 7 can hardly be recognized. In addition, when the light transmittance is 60% or more, the outer surface of the transfer film 7 contained in the main body 31 (inside the main body 31) even when the internal lighting fixture 32 is not lit. It is possible to visually recognize the pattern applied to the surface facing the side surface. The method for producing such an FRP having excellent light transmittance (light transmittance of 25% or more) is not particularly limited, and can be appropriately changed. In the present embodiment, when a fluorescent lamp that emits light having a wavelength of 570 to 600 μm of the main body 31 is used as a lighting fixture, a substantially transparent FRP having a light transmittance of 60% or more is used.

  The transfer film 7 is a thin film having optical transparency and flexibility. On one side, there are patterns such as letters and designs. The transfer film 7 is not particularly limited. For example, when the lighting fixture 32 disclosed in JP-A-2004-45529 and JP-A-2002-182594 is turned off, the transfer film 7 is applied. It is also possible to use a transfer film that displays the pattern applied to the transfer film 7 only when the formed pattern is concealed and the lighting fixture 32 is lit. In the present embodiment, a translucent transfer film 7 having a pattern printed with a paint that does not transmit light is used.

  Below, the attachment method of the transfer film 7 is demonstrated. 3A and 3B are perspective views for explaining the car stopper 110 according to the second embodiment, in which FIG. 3A shows a state in which the main body 31 is removed from the holding member 2 of the car stopper 100, and FIG. 32 shows a state in which the transfer film 7 is inserted, and (c) shows the car stopper 110 in a state in which the transfer film 7 is inserted. First, as shown in FIG. 3A, the main body 31 is removed from the holding member 2 of the car stopper 100 of Embodiment 1, and the upper portion of the holding member 2 is opened. Next, as shown in FIG. 3 (b), the transfer film 7 is rolled into a cylindrical shape with the patterned surface facing inward, inside the main body 31, It is installed outside (that is, between the main body 31 and the lighting fixture 32), and the main body 31 is fitted into the holding member 2 again (see FIG. 3C). In the present embodiment, since the FRP forming the main body 31 is almost transparent, the outside of the transfer film 7 (the surface on which the pattern is not applied) can be clearly seen from the outside of the column 3.

  When the car stop 110 according to the present embodiment is used at night, the lighting fixture 32 is turned on. When the lighting fixture 32 is turned on, the light passes through the transfer film 7 and the main body 31 housed in the column 3. At this time, the pattern formed on the inner surface of the transfer film 7 blocks light emitted from the lighting fixture 32. Therefore, the pattern applied to the inner surface of the transfer film 7 is projected as a shadow pattern outside the column 3. Therefore, the appearance of the car stopper 110 can be variously changed by simply replacing the transfer film 7. In addition, when characters are applied as a pattern on the transfer film 7, information can be transmitted to the surroundings.

  According to the above embodiment, the car stops 100 and 110 include the lighting fixture 32 inside the hollow columnar main body 31 formed of FRP (glass fiber reinforced plastic) having both bending strength and light transmittance. The column 3 is used. Thereby, it is possible to obtain the columnar body 3 having excellent appearance and the vehicle stoppers 100 and 110 including the columnar body 3 while maintaining the strength necessary for the structure.

  In the above embodiment, the case where the column body 3 is used for stopping a car has been described. However, the present invention is not limited to this, and the column body 3 is used for an advertisement tower, a guide tower, and a guide tower indoors and outdoors. It may be used as such. Moreover, you may use the column 3 for pillars, such as an object, a decoration pillar, and a building.

It may be a thing, and the form which made the prismatic thing the hollow body may be sufficient. Alternatively, the shape of the main body 31 may be a form in which a plurality of cylindrical hollow bodies having different outer diameters are connected around the same axis. The shape of the main body 31 may be a hollow column shape.

  Moreover, in the said embodiment, although the receiver 25 exhibited the disk shape and demonstrated the form integrally formed in the 1st upright part 22, this invention is not limited to this, As a receiver A plate-like or rod-like object such as an anchor bolt may be provided inside the first upright portion 22.

Moreover, in the said embodiment, although the lid | cover 4 was engage | inserted by the upper part of the pillar 3 and the form which block | closed the upper part of the pillar 3 was demonstrated, this invention is not limited to this, The lid | cover 4 The part corresponding to may be formed integrally with the main body 31 .

  In Embodiment 2 described above, the pattern is provided only on one surface of the transfer film 7, and the mode in which the surface is located inside the column body 3 has been described. The present invention is not limited to this, and a transfer film 7 having a pattern on both sides may be provided inside the column 3. In this case, when the lighting fixture 32 is not turned on, the pattern applied on the outer surface of the transfer film 7 is displayed outside, and when the lighting fixture 32 is turned on, the pattern applied on the inner surface of the transfer film 7 is displayed outside.
