【考案の詳細な説明】 【０００１】 【考案の属する技術分野】 本考案は、上下水道管や地下電設管の埋設工事、あるいはそれに類似する作業 を行う際の、掘削溝に使用する土留めの上部に装着する転落防止用安全柵に関す るものである。 【０００２】 【従来の技術】 掘削溝に使用する土留め５の長さは、現場状況に合わせて複数の長さの土留め が使用されており、それに対応する安全柵も土留め５の長さに対応した長さの安 全柵を準備しなければならなかった。 【０００３】 【考案が解決しようとする課題】 本考案の課題は、その土留め５の長さに対応した複数の長さの安全柵を伸縮式 とすることにより、長さの異なる土留めにこの伸縮式安全柵６を伸縮させて装着 するものである。 【０００４】 【課題を解決するための手段】 丸形パイプ枠１にストッパー３を取り付け、一方角形パイプ枠２の内側にへこ みをつけて、その組み合わせにより伸縮式とする転落防止用安全柵である。丸形 パイプ枠１の外側にストッパー３を取り付け、そのストッパー３を取り付けた丸 形パイプ枠１を角形パイプ枠２に挿入後、角形パイプ枠２内部のストッパー３が 位置しない端部をパイプ外側より内側に押して角形パイプ枠２の内部にへこみを 加工し、丸形パイプ枠１を最大に伸ばしてもストッパー３が角形パイプ枠２につ けたへこみ４に当たり、そのため丸形パイプ枠１と角形パイプ枠２がはずれない ような構造を有する伸縮機能をもたせた転落防止用安全柵である。 【０００５】 【考案の実施の形態】 本考案は、複数の長さの異なる土留めに対応するものであるので、左右の丸形 パイプ枠１を角形パイプ枠２の内側で伸縮することにより、容易に安全柵の長さ を調整することができる． 【０００６】 【実施例】 土留め５の両端上部には安全柵取り付け金具７を装着することができる。安全 柵取り付け金具７の上部は棒状の形状を有しており、ピン１０を差し込むピン孔 ８が加工されている。同じように伸縮式安全柵６の両端丸パイプ下部にもピン１ ０を差し込むピン９孔が加工されていて、伸縮式安全柵６を安全柵取り付け金具 ７の棒状部に挿入し、ピン１０を介して固定する構造となっている。安全柵取り 付け金具７は土留め５の両端に固定されるため、土留め５の長さに合わせて伸縮 式安全柵６を伸縮し安全柵取り付け金具７に装着する。図１３は下水道工事にお ける管路部の土留め５施工時に、土留め５の両端上部に伸縮式安全柵６を取り付 けた図である。図１４は下水道工事における人孔部の土留め５施工時に、土留め ５の両端上部に伸縮式安全柵６を取り付けた図である。下水道工事では、人孔部 と管路部の土留め５の長さは、通常人孔部より管路部のほうが長くなっている。 そのどちらにも長さの異なる安全柵を用いることなく、伸縮式安全柵６での対応 が可能である。 【０００７】 【考案の効果】 本考案によれば、土留め長さに合わせて複数の安全柵を準備することがないの で、施工上、管理上たいへん有効である。[Detailed description of the invention] [0001] [Technical field to which the invention belongs] The present invention is intended for the construction of water and sewage pipes and underground electrical pipes, or similar work. Safety fence to be attached to the top of earth retaining material used for excavation trenches Things. [0002] [Prior art] The length of the retaining gutter 5 used for the excavation gutter can be varied according to the site conditions. Are used, and the corresponding safety fence has a length corresponding to the length of the earth retaining 5. All fences had to be prepared. [0003] [Problems to be solved by the invention] The problem of the present invention is that a plurality of lengths of safety fence corresponding to the length of the earth retaining 5 are telescopic. The telescopic safety fence 6 can be extended and retracted to earth retaining pieces with different lengths. Is what you do. [0004] [Means for Solving the Problems] Attach the stopper 3 to the round pipe frame 1, It is a safety fence for fall prevention, which is made to be telescopic by combining them. circular A stopper 3 is attached to the outside of the pipe frame 1 and a circle with the stopper 3 attached. After inserting the square pipe frame 1 into the square pipe frame 2, the stopper 3 inside the square pipe frame 2 Press the end that is not located inward from the outside of the pipe to make a dent inside the square pipe frame 2. Even after processing and extending the round pipe frame 1 to the maximum, the stopper 3 Hits 4 indentation, so round pipe frame 1 and square pipe frame 2 do not come off It is a safety fence with a telescopic function having a telescopic function having such a structure. [0005] [Embodiment of the invention] Since the present invention corresponds to earth retaining with different lengths, the left and right round The length of the safety fence can be easily adjusted by expanding and contracting the pipe frame 1 inside the square pipe frame 2. Can be adjusted. [0006] 【Example】 Safety fence mounting brackets 7 can be attached to upper portions of both ends of the earth retaining members 5. safety The upper portion of the fence mounting bracket 7 has a rod-like shape, and has a pin hole into which the pin 10 is inserted. 8 has been machined. In the same way, pin 1 The 9 holes for inserting 0 are processed, and the telescopic safety fence 6 is attached to the safety fence mounting bracket. 7 is inserted into the rod-shaped portion and fixed via a pin 10. Safety fence removal Since the metal fittings 7 are fixed to both ends of the earth retaining 5, they can be expanded and contracted according to the length of the earth retaining 5. The safety fence 6 is extended and retracted and attached to the safety fence mounting bracket 7. Figure 13 shows the sewerage The telescopic safety fence 6 is attached to the upper end of both ends of the retaining wall 5 when the retaining wall 5 is installed FIG. Fig. 14 shows the construction of a sediment retaining work 5 5 is a view in which telescopic safety fences 6 are attached to upper ends of both ends. In sewerage works, human holes And the length of the earth retaining 5 of the pipeline is usually longer in the pipeline than in the human hole. The use of telescopic safety fences 6 without using safety fences of different lengths for either of them Is possible. [0007] [Effect of the invention] According to the present invention, there is no need to prepare multiple safety fences according to the retaining length. It is very effective in construction and management.
