Description
【０００１】[0001]
本考案は、鉄骨階段部分に本工事で手摺を取り付けまでの間に使用する仮設の 手摺に関するものである。 The present invention relates to a temporary handrail that is used before the installation of a handrail in a steel frame staircase in this work.
【０００２】[0002]
従来、鉄骨階段部分に安全対策上から、本格的な手摺が取り付けられるまでの 間に仮設手摺が構築されていた。この、仮設手摺には、種々のものが提案されて いた。図５、６は、従来の仮設手摺の一例を示すものである。図において、鉄骨 階段１の上下に渡って、足場パイプ２を縦に架設するる。次に、この足場パイプ ２に対して、手摺パイプ３を階段部と略平行にクランプ４により取り付け手摺を 形成する。 Traditionally, temporary handrails were built between the safety measures and the installation of full-scale handrails on the steel stairs. Various types of temporary handrails have been proposed. 5 and 6 show an example of a conventional temporary handrail. In the figure, a scaffolding pipe 2 is installed vertically above and below a steel frame staircase 1. Next, the handrail pipe 3 is attached to the scaffold pipe 2 by the clamp 4 so as to form a handrail substantially parallel to the stairs.
【０００３】[0003]
しかし、上述のような従来の鉄骨階段の仮設手摺では、鉄骨階段がある程度（ 高層まで）或いは、取り付けが完了しないと付設することができなかった。した がって、仮設の手摺が取り付けられるまでは、安全上問題があった。 However, in the conventional temporary handrail of the steel stairs as described above, the steel stairs could not be attached to some extent (up to a high level) or after the installation was completed. Therefore, there was a safety issue until the temporary handrail was installed.
【０００４】 本考案の目的は、従来のこのような問題点に鑑み、施工が容易で、しかも種々 の長さの階段に使用することのできる鉄骨階段の仮設手摺を提供することにある 。An object of the present invention is to provide a temporary handrail for a steel staircase that is easy to construct and can be used for stairs of various lengths in view of the above-mentioned conventional problems.
【０００５】[0005]
上記目的を達成するために、本考案は手摺部を成す伸縮自在な横杆と、それを 挿脱可能に支える２本の支柱と、該支柱下部に固定された係止部と、前記２本の 支柱間にピン結合された伸縮部材とを備えて成ることを特徴とする。 In order to achieve the above-mentioned object, the present invention provides an extendable and retractable horizontal rod that forms a handrail part, two columns that support the column rod so that it can be inserted and removed, a locking part that is fixed to the lower part of the column, and the two columns. And an elastic member pin-connected between the columns.
【０００６】[0006]
【作用】 本考案に係る鉄骨階段の仮設手摺は、現場に於いてその階段独自に取り付ける ことができる。また、長さが自由に調整できるので種々の長さの階段に対応する ことができる。[Operation] The temporary handrail of the steel staircase according to the present invention can be attached to the staircase independently on site. Moreover, since the length can be freely adjusted, it is possible to cope with stairs of various lengths.
【０００７】[0007]
以下、本考案の実施例について、図面を参照しつつ説明する。図１は、本考案 の一実施例に係る鉄骨階段の仮設手摺を鉄骨階段に組付けた状態を示す側面図、 図２は、本考案の鉄骨階段の仮設手摺に使用される横杆の要部を示す正面図であ る。ここで、鉄骨階段の仮設手摺は、手摺部を成す伸縮自在な横杆１０と、それ を挿脱可能に支える２本の支柱１１と、該支柱下部に固定された係止部１２と、 前記２本の支柱１１間にピン結合された伸縮部材１３とを備えている。ここで、 横杆１０は、中空パイプ１５とこれに挿通された小径杆１６と、中空パイプ１５ の端部にピン結合された縦杆部１７と、小径杆１６の端部にピン結合された縦杆 部１８とから構成されている。また、縦杆部１７の下部は、小径部１７ａとなり 支柱１１の頭部に装着可能となっている。更に、縦杆部１８の下部も同様に小径 部１８ａとなり支柱１１の頭部に装着可能となっている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing a state in which a temporary handrail of a steel staircase according to an embodiment of the present invention is assembled to the steel staircase, and FIG. 2 is a side view of a horizontal rod used for the temporary handrail of the steel staircase of the present invention. It is a front view which shows a part. Here, the temporary handrail of the steel frame stairs comprises an extendable and retractable horizontal rod 10 forming a handrail portion, two columns 11 for supporting the column rod in an attachable / detachable manner, and a locking portion 12 fixed to the lower portion of the column. The elastic member 13 is pin-connected between the two columns 11. Here, the horizontal rod 10 has a hollow pipe 15, a small diameter rod 16 inserted through the hollow pipe 15, a vertical rod portion 17 pin-connected to the end portion of the hollow pipe 15, and a pin connection to the end portion of the small diameter rod 16. It is composed of a vertical rod portion 18. Further, the lower portion of the vertical rod portion 17 becomes a small diameter portion 17a which can be mounted on the head of the column 11. Further, the lower portion of the vertical rod portion 18 also has a small diameter portion 18a, which can be mounted on the head of the column 11.
【０００８】 支柱１１は、中空パイプであって頭部に横杆１０の縦杆部１７ａ、１８ａが挿 通可能となっている。支柱１１の下部には、切欠き部１９と係止部１２が設けら れており、鉄骨階段のフランジ部２０に固定可能となっている。伸縮部材１３は 、ピン結合により、パンタグラフ状に連結されており、支柱１１間で自在に調整 する事ができる。締結金具１４は、図４に示す如く板状部１４ａと、止めネジ１ ４ｂとから構成されている。板状部１４ａには、長穴１４ｃが形成されておりこ の長穴内を止めネジが遊嵌されている。したがって、支柱１１を結合する場合に 微調整が容易である。The column 11 is a hollow pipe, and the vertical rod portions 17 a and 18 a of the horizontal rod 10 can be inserted into the head portion of the column 11. A notch portion 19 and a locking portion 12 are provided in the lower portion of the column 11, and can be fixed to the flange portion 20 of the steel frame stairs. The elastic members 13 are connected in a pantograph shape by pin connection, and can be freely adjusted between the columns 11. The fastener 14 is composed of a plate-shaped portion 14a and a set screw 14b as shown in FIG. A long hole 14c is formed in the plate-shaped portion 14a, and a set screw is loosely fitted in the long hole. Therefore, it is easy to make fine adjustments when connecting the columns 11.
【０００９】 次に、以上のような構成の鉄骨階段の仮設手摺を使用した施工例について説明 する。まず、鉄骨階段２１を取り付けた後、そのフランジ部２０に支柱１１を係 止部１２で固定する。この時、支柱１１と支柱１１の間は、伸縮部材１３で連結 されているので、鉄骨階段の長さに合わせて自在に伸縮できる。支柱１１の間隔 が決定された後、横杆１０を上から装着する。横杆１０も中空パイプ１５と小径 杆１６とにより、自由に長さを調整できる。横杆１０は、小径部１７ａ、１８ａ を支柱１１の頭部に挿入することにより、装着する。このようにして、鉄骨階段 の仮設手摺を簡易に取り付けることができる。Next, an example of construction using the temporary handrail of the steel frame staircase having the above-described configuration will be described. First, after attaching the steel frame stairs 21, the support columns 11 are fixed to the flange portions 20 by the locking portions 12. At this time, since the columns 11 are connected to each other by the elastic member 13, the columns 11 can be freely expanded and contracted according to the length of the steel stairs. After the distance between the columns 11 is determined, the horizontal rod 10 is mounted from above. The horizontal rod 10 can also be freely adjusted in length by the hollow pipe 15 and the small diameter rod 16. The horizontal rod 10 is mounted by inserting the small-diameter portions 17a and 18a into the head of the column 11. In this way, the temporary handrail of the steel staircase can be easily attached.

以上説明したように、本考案の鉄骨階段の仮設手摺は、手摺部を成す伸縮自在 な横杆と、それを挿脱可能に支える２本の支柱と、該支柱下部に固定された係止 部と、前記２本の支柱間にピン結合された伸縮部材とで構成したので、一層の鉄 骨階段の施工後であっても、すぐに使用することができる。この為、施工作業の 効率化を図ることができる。更に、鉄骨階段の手摺が即座に使用できるので、現 場において安全な昇降施設を確保できる。 As described above, the temporary handrail of the steel staircase according to the present invention comprises an extendable and retractable horizontal rod that constitutes a handrail part, two columns that support the rod to be inserted and removed, and a locking part fixed to the lower part of the column. And the elastic member pin-joined between the two columns, it can be used immediately even after the construction of one layer of steel stairs. Therefore, the efficiency of construction work can be improved. Furthermore, since the handrails of steel stairs can be used immediately, a safe lifting facility can be secured in the field.
