PROBLEM TO BE SOLVED: To fix a safety fence without bringing in a weight and without beforehand processing a manhole cover.SOLUTION: A safety fence is formed of plural fence-shaped members, and comprises coupling bodies for coupling lower parts of the plural fence-shaped members to each other to hold the shape of the safety fence. The fence-shaped member comprises plural vertical frames, lateral frames connecting upper parts of the plural vertical frames to each other, and other lateral frames connecting lower parts of the plural vertical frames to each other. The coupling body connects the lower parts of the vertical frames of the plural fence-shaped members to each other. A heavy load placement part is provided at a central upper part of the coupling body for placement of a heavy load. Further, the coupling body has strength and a length for keeping the shape of the safety fence at a predetermined width, and comprises a body part provided with the heavy load placement part for placement of a heavy load, and coupling parts provided at opposite ends of the body part for coupling to the lower parts of the fence-shaped members.SELECTED DRAWING: Figure 3

    【課題】重りを持ち込むことなく、またマンホール蓋に予め加工を施すことなく、安全柵を固定する。【解決手段】安全柵は、複数の柵状部材で構成されている。また、前記複数の柵状部材の下部どうしを結合して前記安全柵の形状を保持する結合体を備えている。前記柵状部材は、複数の縦枠と、前記複数の縦枠の上部どうしを接続する横枠と、前記複数の縦枠の下部どうしを接続する横枠を備え、前記結合体は前記複数の柵状部材の前記縦枠の下部どうしを接続する。また、前記結合体の中央上部に、重量物を載置するための、重量物載置部が設けられている。更に、前記結合体は、前記安全柵の形状を所定幅に保持する長さと強度を持ち、且つ重量物を載置する重量物載置部を備える本体部と、前記本体部の両端部に設けられ、前記柵状部材の下部に結合するための結合部を備える。【選択図】図3
