A reinforcing member 5 is fixed to the column 1 of the present embodiment so as to close the lower end of the base portion 13.
The column 1 is configured to be detachably fixed by inserting the lower end portion of the base 13 to which the reinforcing member 5 is fixed into a circular recess 21 provided on the upper surface of the base 2. Specifically, after being inserted into the recess 21 provided in the base 2, the male screw of the fixing screw N is inserted from the outer surface of the base 2 toward the lower end portion of the base 13, and the base 13 is penetrated. Thus, the base 2 and the base 13 are fixed by screwing into the reinforcing member 5. By fixing as described above, if the fixing screw N is removed, the fixing between the base 13 and the base 2 can be released, and the column body 1 and the base 2 can be detachably fixed. In this embodiment, the reinforcing member 15 is made of a material harder than the column portion 1 so that the reinforcing member 5 can be firmly coupled to the male screw portion of the fixing screw N into which the reinforcing member 5 is screwed. Although a nitrile styrene copolymer (AS resin) is used, other hard synthetic resins such as polyethylene, ABS resin, FRP, polycarbonate resin, and AAS resin, metals, and the like can be suitably used.

尚、図４及び図５において、図面の簡略化のために、補強用部材５の図示を省略している。 The column 1 is provided in a shape including a cylindrical base 13 at the lower portion, an intermediate portion 12 that changes to a plate-shaped outer shape, and a plate portion 11 having a plate-shaped outer shape above it. These shapes of the column body 1 of the present embodiment are formed by hot pressing a single pipe body P.
4 is a cross-sectional view taken along the line AA of FIG. 2, FIG. 2 is a cross-sectional view taken along the line BB of FIG. 1, and FIG. 6 is a view illustrating a situation in which the column 1 of FIG. Is a diagram showing before hot press processing, and (b) is a diagram showing after hot press processing.
In FIGS. 4 and 5, the reinforcing member 5 is not shown for the sake of simplicity.

パイプ体Ｐは、図４（イ）に示すように円筒形状のパイプである。
パイプ体Ｐは、矢印で示されるように、その上部分が押しつぶされるように前後両方向から熱プレス加工により押圧され、円筒形状の筒壁が上端に至るまで平板状に成型されて、板形状の外形の板部１１が形成されている。
そして、前記の熱プレス加工が施されていないパイプ体Ｐの下部分は円筒形状の基部１３とし、この基部１３と板部１１との間に、板形状から円筒形状へ形状を変化させる中間部１２が形成されるように設けている。
前記柱体１の板部１１、中間部１２、基部１３を一の部材に形成させることで、これらの部位の接続部分が生じないので、立設する柱体の板部１１に車両などが接触したときに、接続部分に力が集中して破壊され、板部１１が外れてしまう等の問題が抑制できる。
また、板形状の外形の板部１１と円筒形状の基部１３との間に、板形状から円筒形状へ徐々に形状が変化する中間部１２を設けることで、これらの間の柱体１の筒壁に力が集中する箇所が生じにくくなされ、柱体１の損傷が抑制できる。
また、本実施形態の柱体１は、１本のパイプ体Ｐを熱プレス等により前後両方向から押圧することで、前記の板部１１、中間部１２、基部１３を容易に形成させることができる。また前記の方法は、射出成型など他の成型方法と比較して、その筒壁の肉厚を柱体１の上端から下端に至るまで容易に等しく形成させることができるので、柱体１へ外力がかかったときに筒壁の薄い部分に力が集中することがなく、柱体１の損傷を抑制できる。 The pipe body P is a cylindrical pipe as shown in FIG.
As indicated by the arrow, the pipe body P is pressed by hot pressing from both the front and rear directions so that the upper part is crushed, and is formed into a flat plate shape until the cylindrical cylindrical wall reaches the upper end. An outer plate 11 is formed.
The lower part of the pipe body P not subjected to the hot pressing is a cylindrical base portion 13, and an intermediate portion that changes the shape from a plate shape to a cylindrical shape between the base portion 13 and the plate portion 11. 12 is formed.
Since the plate portion 11, the intermediate portion 12, and the base portion 13 of the column 1 are formed as one member, a connection portion of these parts does not occur, so that a vehicle or the like contacts the plate portion 11 of the column body to be erected. When this is done, it is possible to suppress problems such as the force being concentrated on the connecting portion and being broken, and the plate portion 11 coming off.
Further, by providing an intermediate portion 12 whose shape gradually changes from a plate shape to a cylindrical shape between a plate-shaped outer plate portion 11 and a cylindrical base portion 13, the cylinder of the column 1 between them is provided. The location where force concentrates on the wall is less likely to occur, and damage to the column 1 can be suppressed.
Moreover, the column body 1 of this embodiment can form the said board part 11, the intermediate part 12, and the base 13 easily by pressing the one pipe body P from the front-back both directions with a hot press etc. FIG. . In addition, the above method can easily form the wall thickness of the cylindrical wall from the upper end to the lower end of the column body 1 as compared with other molding methods such as injection molding. Therefore, the force does not concentrate on the thin part of the cylindrical wall when applied, and damage to the column 1 can be suppressed.

本実施形態の板部１１は、平板形状に成型された、前方向の壁部１１ａと後方向の筒壁１１ｂとの間にスリット形状の隙間Ｓが形成されるように設けられている。図３に示されるように、前記隙間Ｓは上端が上方へ開口すると共に、下方に向かっては柱体１の基部１３の中空部分に通じるように形成されている。
柱体１に車両などが接触して、踏みつぶされるように変形するとき、柱体１は基部１３で折れ曲がるように変形するが、基部１３の中空部分と外部とが連通するように前記隙間Ｓが形成されることで、踏みつぶされた柱体１内部の空気が隙間Ｓを通り道として外部へ排出されるので、内部の空気の圧力増大による柱体１の破裂などの損傷を防止できる。
また、隙間Ｓを中空部分とする板形状の外形の筒体に板部１１を形成することで、隙間Ｓの無い中密の板形状と比較してその断面強度が増大し、自重や風を受ける等の要因による撓みなどの変形が板部１１に容易に生じないので、板部１１に設けた道路標示がよく視認できるようになされる。
また、本実施形態の柱体１は、スリット形状の隙間Ｓを上方に開口させて柱体１内部の空気の通り道としているが、この空気の通り道の形成方法はこれに限るものではなく、前記の空気の通り道として必要な一部を残してスリット形状の前記隙間Ｓを別部材で塞いでもよく、前記の空気の通り道を柱体１の上部以外に形成させて前記隙間Ｓを全て塞いでもよい。 The plate portion 11 of the present embodiment is provided such that a slit-shaped gap S is formed between the front wall portion 11a and the rear cylindrical wall 11b, which are molded into a flat plate shape. As shown in FIG. 3, the gap S is formed so that its upper end opens upward and communicates with the hollow portion of the base portion 13 of the column 1 downward.
When a vehicle or the like comes into contact with the column 1 and deforms so as to be crushed, the column 1 is deformed so as to be bent at the base 13, but the gap S so that the hollow portion of the base 13 communicates with the outside. As a result of the formation, the air inside the crushed column 1 passes through the gap S and is discharged to the outside, so that damage such as rupture of the column 1 due to an increase in the internal air pressure can be prevented.
Further, by forming the plate portion 11 in a cylindrical body having a plate shape with the gap S as a hollow portion, its cross-sectional strength is increased compared to a solid plate shape without the gap S, and its own weight and wind are reduced. Since deformation such as bending due to factors such as receiving does not easily occur in the plate portion 11, the road marking provided on the plate portion 11 can be seen well.
Further, the column body 1 of the present embodiment opens the slit-shaped gap S upward to form an air passage inside the column body 1, but this air passage formation method is not limited to this, The slit-shaped gap S may be closed with another member while leaving a part necessary for the air passage, or the air passage may be formed at a portion other than the upper portion of the column 1 to close the gap S. .

本実施形態の柱体１は、図１に示された柱体１と同様に、板部１１を標示面として道路標示を形成させ、円筒形状の基部１３に補強用部材５を固定させて、ベース２に着脱自在に立設されるように設けられており、パイプ体Ｐに熱プレス加工を施して形成させた板部１１の断面形状が、図１に示された実施形態と異なる事項でる。
具体的には、本実施形態の板部１１は、熱プレス加工によってパイプＰの筒壁が成型されて、板部１１の幅方向中央寄りに前面及び後面が平面となされた平面部１１ｂが形成されており、各平面部１１ｂの筒壁の間にスリット形状の隙間Ｓが形成されるように設けられている。
そして、板部１１の幅方向端部分には、筒壁が外方へ弧を描くように膨らむように形成された縁部１１ｃが、上下方向へ沿って前記平面部の両脇にそれぞれ形成されており、板部１１の厚さ方向の大きさにおいて、各縁部１１ｃが前後両方向に膨らんで、前記平面部１１ｂより大きくなるように設けられている。 FIG. 7 is a view showing another embodiment of the pillar body 1 of the road marking body according to the present invention, (A) is a plan view, and (B) is a front view.
As in the case of the column 1 shown in FIG. 1, the column 1 of the present embodiment forms a road marking with the plate portion 11 as a marking surface, and the reinforcing member 5 is fixed to the cylindrical base 13. The cross-sectional shape of the plate part 11 which is provided so as to be detachably installed on the base 2 and is formed by subjecting the pipe body P to hot pressing is different from the embodiment shown in FIG. .
Specifically, the plate portion 11 of the present embodiment is formed by forming a cylindrical wall of the pipe P by hot pressing, and forming a flat portion 11b whose front and rear surfaces are flat toward the center of the plate portion 11 in the width direction. It is provided so that a slit-shaped gap S is formed between the cylindrical walls of each flat part 11b.
And the edge part 11c formed so that a cylindrical wall may swell so that an arc may be drawn outward may be formed in the width direction edge part of the board part 11 on both sides of the said plane part along an up-down direction, respectively. In the thickness direction of the plate part 11, each edge part 11c is provided so as to swell in both the front and rear directions and to be larger than the flat part 11b.

上記のように平面部１１ｂの両脇に、厚さ方向の大きさがより大きな縁部１１ｃをそれぞれ設けることで、縁部１１ｃを設けない形状と比較して板部１１の断面強度が増大し、自重や風を受ける等の要因による撓みなどの変形が板部１１に容易に生じないようになされる。
また、本実施形態の板部１１は、図１の実施形態と同様に、各平面部１１ｄの筒壁の間にスリット形状の隙間Ｓを形成させて、この隙間Ｓを中空部分とする筒形状に板部１１を形成させることで、その断面強度が増大するようになされている。 As described above, the cross-sectional strength of the plate portion 11 is increased by providing the edge portions 11c that are larger in the thickness direction on both sides of the flat surface portion 11b as compared with the shape in which the edge portions 11c are not provided. Deformation such as bending due to factors such as its own weight or wind is prevented from easily occurring in the plate portion 11.
Further, the plate portion 11 of the present embodiment is formed in a cylindrical shape in which a slit-shaped gap S is formed between the cylindrical walls of each flat portion 11d, and the gap S is a hollow portion, as in the embodiment of FIG. By forming the plate portion 11 in the cross section, its cross-sectional strength is increased.

また、本実施形態の柱体１の前記隙間Ｓや、各縁部１１ｃの内側に形成される隙間は、図１の実施形態の柱体１と同様に柱体１の上方に開口するように設けられている。そして、柱体１が変形する際に、基部１３の中空部分の空気を外方へ排出させるための空気の通り道となるようになされており、柱体１の破損を防止している。 In addition, the gap S of the column body 1 of the present embodiment and the gap formed inside each edge portion 11c are opened above the column body 1 like the column body 1 of the embodiment of FIG. Is provided. And when the column 1 deform | transforms, it is made to become the passage of the air for discharging the air of the hollow part of the base 13 to the outward, and the damage to the column 1 is prevented.

本実施形態の板部１１は、前面および後面が平面に形成された平面部１１ｄを標示面として道路標示を設けるようになされている。そして、厚さ方向の大きさが平面部１１ｄより大きな縁部１１ｃをこの平面部の両脇に形成させることで、板部１１に車両が接触したり、柱体１が車両などに踏みつぶされる等したときに、縁部１１ｄが車両や路面に接触するようになされており、これら車両や路面を平面部１１ｄに直接接触させないように設けることで、平面部１１ｄに設けた道路標示の損傷や汚損を低減させ、この板部１１を備えた柱体１が立設された道路用標示体の標示機能が維持されるようになされている。 The plate portion 11 of the present embodiment is configured to provide road markings with a flat surface portion 11d having a front surface and a rear surface formed as flat surfaces as a marking surface. Then, by forming the edge portions 11c whose size in the thickness direction is larger than the flat surface portion 11d on both sides of the flat surface portion, the vehicle comes into contact with the plate portion 11 or the column body 1 is crushed by the vehicle or the like. The edge portion 11d comes into contact with the vehicle and the road surface when they are equal to each other. By providing the vehicle and the road surface so as not to directly contact the flat portion 11d, the road marking provided on the flat portion 11d can be damaged. The labeling function of the road marking body in which the column body 1 having the plate portion 11 is erected is maintained so as to reduce the fouling.
