FIG. 1 shows a handrail 1 installed on a steel staircase S, and the handrail 1 is a pair of divisions connected to each other so that the handrail can be extended and contracted in the length direction. It consists of handrails 1A and 1B, and one of the divided handrails 1A is made up of handrail stanchions 2 and 3 and upper and lower handrail horizontal members 4 and 5, respectively, which are made of steel pipe material. It is divided and formed at the intersection with the member 5, and is connected to the lower handrail cross member 5 and the upper handrail cross member 4. The other divided handrail 1B is composed of a handrail post 6 and upper and lower handrail horizontal members 7 and 8 formed of a steel pipe material having a diameter smaller than that of the steel pipe material for forming the one divided handrail 1A. The handrail cross members 7, 8 are telescopically inserted into the upper and lower handrail cross members 4, 5 of the one divided handrail 1A, respectively, and by means of bolts or the like provided on the handrail cross members 4, 5 with a required length of rollers. Fixed.

【0007】 前記各分割手摺1A,1Bにおける各手摺支柱2,3,6の下端には、鉄骨階 段Sの側板Pに嵌合可能な鋼板製のコ字形材9が取付けられている。図2及び図 3から明らかなように、各コ字形材9は内外両側板部10,11と上板部12と からなるもので、上板部13が各支柱2,3,6の下端面13に溶接により固着 されている。尚、各手摺支柱2,3,6の下端面13は階段側板Pの傾斜角に対 応する角度で斜切りされた斜端面となっている。A U-shaped member 9 made of a steel plate that can be fitted to the side plate P of the steel frame step S is attached to the lower ends of the handrail columns 2, 3 and 6 of the divided handrails 1A and 1B. As is clear from FIGS. 2 and 3, each U-shaped member 9 is composed of inner and outer both side plate portions 10 and 11 and an upper plate portion 12, and the upper plate portion 13 is a lower end surface of each of the columns 2, 3 and 6. It is fixed to 13 by welding. In addition, the lower end surface 13 of each of the handrail support columns 2, 3, 6 is a slant end surface which is slanted at an angle corresponding to the slant angle of the stair side plate P.

【0008】 前記各コ字形材9の内外両側板部10,11には横方向の貫通ねじ孔14,1 5が設けてあって、両ねじ孔14,15に対し1本のクランプボルト16が付け 替え可能に螺合される。図3に示すように、このクランプボルト16にはその先 端径小軸部16aに皿ばね17が嵌挿してあって、割りリング18によって抜け 止めされている。The inner and outer both side plate portions 10 and 11 of each U-shaped member 9 are provided with through screw holes 14 and 15 in the lateral direction, and one clamp bolt 16 is provided for both screw holes 14 and 15. It is replaceably screwed. As shown in FIG. 3, a disc spring 17 is fitted into the clamp bolt 16 at its tip end small diameter shaft portion 16a and is prevented from coming off by a split ring 18.

【0009】 上記のような構成よりなる手摺1を階段側板Pに取付けるには、各手摺支柱2 ,3,6下端のコ字形材9を階段側板Pに跨嵌して、図3に示すように当該コ字 形材9の上板部12を階段側板Pの上端面に当接させると共に、一方の側板部1 1に取付けたクランプボルト16の皿ばね17と、クランプボルト16を取付け ていない他方の側板部10との間に階段側板Pを挟み込み、しかして前記クラン プボルト16を締め付けることにより、皿ばね17と側板部10とで階段側板P を挟着して、コ字形材9を階段側板Pに固着する。これによって手摺1を階段側 板Pの定位置に確実強固に立設固定することができる。To attach the handrail 1 having the above-mentioned configuration to the stairs side plate P, the U-shaped members 9 at the lower ends of the handrail support columns 2, 3, 6 are fitted over the stairs side plate P, as shown in FIG. The upper plate portion 12 of the U-shaped member 9 is brought into contact with the upper end surface of the stair side plate P, and the disc spring 17 of the clamp bolt 16 attached to one side plate portion 11 and the clamp bolt 16 are not attached. By sandwiching the stair side plate P between the other side plate part 10 and tightening the clamp bolt 16, the disc spring 17 and the side plate part 10 sandwich the stair side plate P, and the U-shaped member 9 is staircased. It sticks to the side plate P. As a result, the handrail 1 can be reliably and firmly erected and fixed at a fixed position on the stairs side plate P.

【0010】 この手摺1の取付けにあたっては、各手摺支柱2,3,6下端のコ字形材9に おける内外両側板部10,11のいずれか一方側の貫通ねじ孔14又は15に予 めクランプボルト16を螺合しておく。この場合、手摺1を取付けるべき階段側 板Pの外側面近傍に何も障害物が無いときは、図4に例示するように各コ字形材 9の外側板部11側にクランプボルト16を取付けるようにすれば、クランプボ ルト16が階段側板Pの内側に突出せず、通行に支障を来すようなことがない。Before mounting the handrail 1, the handrails 2, 3 and 6 are pre-clamped in the through screw holes 14 or 15 on either side of the inner and outer both side plate portions 10 and 11 of the U-shaped members 9 at the lower ends. The bolt 16 is screwed in advance. In this case, when there is no obstacle near the outer surface of the stairs side plate P to which the handrail 1 is to be attached, the clamp bolt 16 is attached to the outer plate portion 11 side of each U-shaped member 9 as illustrated in FIG. By doing so, the clamp bolt 16 does not project to the inside of the stair side plate P, and there is no obstacle to traffic.

【0011】 また、階段側板Pの外側面近傍に何らかの障害物があって、コ字形材9におけ る外側板部11の貫通ねじ孔15にクランプボルト16を螺合したのではクラン プボルト16が障害物に当たる恐れがあったり、或いは当たるようなことはない けれどもクランプボルト16の締め付け操作がやりにくいような状況下において は、図5に示すようにクランプボルト16をコ字形材9の内側板部10側に付け 替えておけばよい。またこの場合に、上記障害物が階段側板Pの外側全域に亘る ようなときは、全てのコ字形材9についてクランプボルト16を内側板部10側 に取付ける必要があるが、階段側板P外側面の一部分に障害物が対向隣接するよ うな場合は、必要なコ字形材9についてのみクランプボルト16を内側板部10 側に取付ければよい。Further, if there is an obstacle near the outer surface of the stairs side plate P and the clamp bolt 16 is screwed into the through screw hole 15 of the outer plate portion 11 of the U-shaped member 9, the clamp bolt 16 will not work. In a situation where the clamp bolt 16 may be hit by an obstacle or may not hit, but it is difficult to tighten the clamp bolt 16, as shown in FIG. 5, the clamp bolt 16 is attached to the inner plate portion of the U-shaped member 9. It should be replaced on the 10 side. Further, in this case, when the obstacle extends over the entire outside of the stairs side plate P, it is necessary to attach the clamp bolts 16 to the inside plate portion 10 side for all the U-shaped members 9, but When an obstacle faces and adjoins a part of the above, the clamp bolt 16 may be attached to the inner plate portion 10 side only for the required U-shaped member 9.

【0012】 上記実施例では、階段Sの片側の側板Pについてのみ説明したが、両側の階段 側板Pにそれぞれ手摺1を取付ける場合も、上述の説明と同様な方法で取付けを 行うことができる。また実施例では、クランプボルト16の先端部に皿ばね17 を取付けているが、この皿ばね17を省略し、クランプボルト16の先端面を直 接階段側板Pに押し付けるようにしてもよい。In the above-described embodiment, only the side plate P on one side of the stairs S has been described. However, even when the handrails 1 are attached to the stair side plates P on both sides, the mounting can be performed in the same manner as described above. Further, in the embodiment, the disc spring 17 is attached to the tip portion of the clamp bolt 16, but the disc spring 17 may be omitted and the tip surface of the clamp bolt 16 may be pressed directly against the stair side plate P.

【考案の作用及び効果】[Operation and effect of the device]

本考案の鉄骨階段用仮設手摺によれば、手摺支柱下端のコ字形材を階段側板に 跨嵌して、当該コ字形材の内外両側板部のうち、いずれか一方の側板部に取付け たクランプボルトの先端部と、クランプボルトを取付けていない他方の側板部と の間に階段側板を挟み込んだ状態で、前記クランプボルトを締め付けることによ り、このクランプボルト先端部と前記他方の側板部とで階段側板を挟着して、前 記コ字形材を階段側板に固着する。これによって手摺を階段側板の定位置に確実 強固に立設固定することができる。 According to the temporary handrail for steel stairs of the present invention, the U-shaped member at the lower end of the handrail strut is straddled over the stair side plate, and the clamp is attached to either one of the inner and outer side plate parts of the U-shaped member. With the step side plate sandwiched between the tip of the bolt and the other side plate where the clamp bolt is not attached, the clamp bolt is tightened by tightening the clamp bolt and the other side plate. Sandwich the stairs side plate with, and fix the above U-shaped material to the stairs side plate. As a result, the handrail can be reliably and firmly erected and fixed at a fixed position on the stairs side plate.

【0014】 この場合、手摺を取付けるべき階段側板の外側面近傍に何も障害物が無いとき は、コ字形材の外側板部側にクランプボルトを取付けるようにすれば、クランプ ボルトが階段側板の内側に突出せず、通行等に支障を来すようなことがない。ま た、階段側板の外側面近傍に何らかの障害物があって、前記コ字形材における外 側板部側にクランプボルトを取付けたのではクランプボルトが障害物に当たる恐 れがあったり、或いは当たるようなことはないけれどもクランプボルトの締め付 け操作がやりにくいような状況下においては、クランプボルトをコ字形材の内側 板部側に付け替えればよい。In this case, when there are no obstacles near the outer surface of the staircase side plate to which the handrail is to be attached, the clamp bolt can be attached to the staircase side plate by attaching the clamp bolt to the outer side plate portion side of the U-shaped member. It does not project inward and does not interfere with traffic. Also, if there is an obstacle near the outer surface of the staircase side plate and the clamp bolt is attached to the outer side plate portion of the U-shaped member, there is a fear that the clamp bolt may hit the obstacle, or it may hit. However, in situations where it is difficult to tighten the clamp bolts, the clamp bolts can be replaced with the inner plate of the U-shaped member.

【0015】 上記のように手摺支柱下端に設けたコ字形材の内外いずれか一方の側板部の貫 通ねじ孔にねじ込んだ1本のクランプボルトを締め付けるだけでよいから、取付 け作業更には取外し作業が極めて簡単容易に行えると共に、階段側板の外側に障 害物が存在する場合でも手摺支柱の取付が容易に可能となる。As described above, it suffices to tighten only one clamp bolt screwed into the through-screw hole of either the inner or outer side plate portion of the U-shaped member provided at the lower end of the handrail strut. The work is extremely easy and easy, and even if there are obstacles on the outside of the stairs side plate, the handrail support columns can be easily attached.
