PRECEDING HANDRAIL FOR CURVE TYPE SCAFFOLD
PROBLEM TO BE SOLVED: To provide a preceding handrail higher in stability in construction of a curve type scaffold.SOLUTION: A preceding handrail installed between columns for constituting a curve type scaffold, comprises at least a horizontal member arranged between the columns and a pair of diagonal members for connecting one end to both ends of the horizontal member and arranged so as to mutually cross under the horizontal member. The diagonal members comprise at least a long size-shaped intermediate part, an upper side connection part provided on one end side of the intermediate part and rotatably installed in a wedge hole provided in a flange of the column and a lower side connection part provided on the other end side of the intermediate part and rotatably installed in the wedge hole provided in the flange of te column. The upper side connection part and the lower side connection part comprise a contact surface for contacting with the column in an upper part of the flange when installed with the respective columns, and the contact surface is constituted in a circular arc shape in a plan view, and thereby enhances contact stability of the preceding handrail and the column.SELECTED DRAWING: Figure 5
【課題】曲線型足場の構築において、より安定性の高い先行手摺りを提供すること。【解決手段】曲線型足場を構成する支柱間に取り付ける先行手摺りであって、支柱間に配置する、水平材と、水平材の両端に一端を連結するとともに、水平材の下方で互いに交差するように配置する、一対の斜材と、を少なくとも有する。前記斜材は、長尺状の中間部と、中間部の一端側に設け、支柱のフランジに設けたクサビ孔に回動自在に取り付けるための上側接続部と、中間部の他端側に設け、支柱のフランジに設けたクサビ孔に回動自在に取り付けるための下側接続部と、を少なくとも備える。前記上側接続部および下側接続部は、各支柱との取付時に、フランジの上部で支柱と接触する、接触面を有し、前記接触面を平面視して円弧状に構成することで、先行手摺りと支柱との接触安定性を高める。【選択図】図５
