TEMPORARY HANDRAIL ASSEMBLY TOOL
PROBLEM TO BE SOLVED: To provide a tool capable of assembling a temporary handrail with excellent workability, by using a steel pipe.SOLUTION: A bolt 23 of penetrating through a bolt through-hole 29a of one T-shaped sandwiching member 22a, is threadedly engaged with/penetrated through a through-screw hole 29b provided in the other T-shaped sandwiching member 22b, and a nut 24 is nonrotatably fixed to an end part of the bolt 23 projecting from this through-screw hole, and a compression coil spring 25 is fitted to the bolt 23 between a pair of T-shaped sandwiching members 22a and 22b, and when the pair of T-shaped sandwiching members 22a and 22b are held in a maximum separation state of abutting on a bolt head part 23a and the nut 24 by energization force of the compression coil spring 25, a vertical part 26 of the pair of T-shaped sandwiching members 22a abd 22b is loosely fitted to an upper end part of a steel pipe 4 for a column, and a steel pipe 5 for a handrail can be loosely fitted to a horizontal part 27 of the pair of T-shaped sandwiching members 22a and 22b.SELECTED DRAWING: Figure 2
【課題】鋼管を利用して仮設手摺りを作業性良く組み立てることが出来る用具を提供する。【解決手段】一方のＴ字形挟持部材２２ａのボルト貫通孔２９ａを貫通したボルト２３が、他方のＴ字形挟持部材２２ｂに設けられた貫通ネジ孔２９ｂを螺合貫通し、この貫通ネジ孔から突出するボルト２３の端部には、ナット２４が回転不能に固定され、一対のＴ字形挟持部材２２ａ，２２ｂの間でボルト２３に圧縮コイルバネ２５が嵌装され、一対のＴ字形挟持部材２２ａ，２２ｂが、圧縮コイルバネ２５の付勢力によってボルト頭部２３ａとナット２４に当接する最大離間状態に保持されているとき、一対のＴ字形挟持部材２２ａ，２２ｂの垂直部２６を支柱用鋼管４の上端部に遊嵌させると共に、一対のＴ字形挟持部材２２ａ，２２ｂの水平部２７に手摺り用鋼管５を遊嵌させることが出来る構成。【選択図】図２
