ところで、上記防護ネット等は、広い面積が被えるような大きさで、しかも容 易に破れないよう頑丈に作られており、相当な重量を有しているので、防護ネッ ト等を引上げて緊張させながら縛るのは非常に困難であった。そのため張設した 防護ネット等にたるみが生じ、見た目が悪いうえに、仮設足場とネット間及び隣 接するネット間に大きな隙間が発生し、この隙間から落下物が飛び出すおそれが あった。 By the way, the above-mentioned protective nets are large enough to cover a large area, and are made tough so as not to be easily broken, and have a considerable weight. It was very difficult to tie it up with tension. As a result, the stretched protective net, etc., sagged, resulting in an unsightly appearance. In addition, a large gap was created between the temporary scaffold and the net, and between the adjacent nets.

以下、この考案の実施例を添付図面に基づいて説明する。 図1及び図2に示すように、防護ネット1の緊張装置2は、仮設足場の縦パイ プ3に固定するためのクランプ金具4と、このクランプ金具4に取付けたワイヤ ー5の巻取りドラム6と、このドラム6の回転操作機構7と、ドラム6から引出 したワイヤー5の下端に設けた防護ネット1の係止部8との組合せによって構成 されている。 An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, a tensioning device 2 of a protective net 1 includes a clamp metal fitting 4 for fixing to a vertical pipe 3 of a temporary scaffold, and a winding drum of a wire 5 attached to the clamp metal fitting 4. 6, a rotation operation mechanism 7 of the drum 6, and a locking portion 8 of the protective net 1 provided at the lower end of the wire 5 pulled out from the drum 6.
【0008】 上記巻取りドラム6は、クランプ金具4における垂直壁9の内面側に水平状態 で回動自在となるよう軸止され、このドラム6の周囲に巻回したワイヤー5の上 端はドラム6に固定されていると共に、ドラム6から引出したワイヤー5はクラ ンプ金具4の下壁に設けた孔10を通過して下方に引出されている。The winding drum 6 is axially fixed to the inner surface of the vertical wall 9 of the clamp fitting 4 so as to be rotatable in a horizontal state, and the upper end of the wire 5 wound around the drum 6 is a drum. The wire 5 fixed to the drum 6 and pulled out from the drum 6 passes through a hole 10 provided in the lower wall of the clamp metal member 4 and is pulled out downward.
【0009】 ドラム6の回転操作機構7は、クランプ金具4における垂直壁9の外面にドラ ム6と同軸となるよう取付けた六角頭部11と、垂直壁9の内面側にドラム6と 一体に回転するよう設けたラチェット爪車12と、このラチェット爪車12に対 して先端が係脱するよう垂直壁9の内面に取付けたラチェット爪13及びこのラ チェット爪13を操作するため垂直壁9の外面に設けたレバー14とによって構 成され、ラチェット爪13とラチェット爪車12は係合状態でドラム6がワイヤ ー5の引出し方向に回転するのを阻止していると共に、レバー14でラチェット 爪13とラチェット爪車12の係合を解くと、ドラム6はワイヤー5の引出し方 向に回転自在となる。The rotation operation mechanism 7 of the drum 6 is a hexagonal head 11 mounted on the outer surface of the vertical wall 9 of the clamp 4 so as to be coaxial with the drum 6, and a drum 6 on the inner surface side of the vertical wall 9 integrally with the drum 6. The ratchet pawl 12 provided to rotate, the ratchet pawl 13 attached to the inner surface of the vertical wall 9 so that the tip of the ratchet pawl 12 is engaged with and disengaged from the ratchet pawl 12, and the vertical wall 9 for operating the ratchet pawl 13. The ratchet pawl 13 and the ratchet pawl wheel 12 prevent the drum 6 from rotating in the pulling-out direction of the wire 5 while the ratchet pawl 13 and the ratchet pawl wheel 12 are engaged with each other. When the claw 13 and the ratchet wheel 12 are disengaged, the drum 6 becomes rotatable in the drawing direction of the wire 5.
【0010】 また、ドラム6をワイヤー5の巻取り方向に回転させるには、六角頭部11に ボックススパナ等の工具を接続しこの六角頭部11とドラム6を一体に回転させ ればよい。In order to rotate the drum 6 in the winding direction of the wire 5, a tool such as a box spanner may be connected to the hexagonal head 11 and the hexagonal head 11 and the drum 6 may be integrally rotated.
【0011】 前記ワイヤー5の下端に取付けた係止部8は、矩形状プレート15の表面で上 下四隅に有頭ピン16を突設し、プレート15の上部中央をワイヤー5の下端に 吊下げて取付けるようにしたものであり、防護ネット1のコーナに設けたはと目 17を有頭ピン16に引掛けることにより、四枚の防護ネット1を係止できるよ うになっている。The locking portion 8 attached to the lower end of the wire 5 has headed pins 16 protruding from the upper and lower four corners of the surface of the rectangular plate 15, and the upper center of the plate 15 is hung from the lower end of the wire 5. The four protective nets 1 can be locked by hooking eyelets 17 provided at the corners of the protective net 1 on the headed pins 16.
【0012】 なお、係止部8は図示に限定されるものではなく、例えば防護ネット1のはと 目17を引掛けるフックをX字状に配置した構造を採用してもよい。The locking portion 8 is not limited to the one shown in the figure, and for example, a structure in which hooks for catching the eyelets 17 of the protective net 1 are arranged in an X shape may be adopted.
【0013】 この考案の緊張装置2は上記のような構成であり、仮設足場の縦パイプ3に張 設した防護ネット1を緊張させるには、先ずネット1の上端よりも上方の位置に 、クランプ金具4で緊張装置2を固定し、ドラム6からワイヤー5を所定長さ引 出した状態で係止部8の各有頭ピン16にネット1のはと目17を引っ掛ける。The tensioning device 2 of the present invention has the above-mentioned structure, and in order to tension the protective net 1 stretched on the vertical pipe 3 of the temporary scaffold, first, the clamp 1 is placed at a position above the upper end of the net 1. The tension device 2 is fixed by the metal fitting 4, and the wire 5 is pulled out from the drum 6 by a predetermined length, and the eyelets 17 of the net 1 are hooked on the headed pins 16 of the locking portion 8.
【0014】 次に、回転操作機構7の六角頭部11を適当な工具で回してドラム6を正転さ せ、ワイヤー5を巻上げて係止部8を上昇させると、下位のネット1が引上げら れて緊張する。Next, the hexagonal head 11 of the rotary operation mechanism 7 is rotated by an appropriate tool to rotate the drum 6 in the normal direction, and the wire 5 is wound up to raise the locking portion 8 and the lower net 1 is pulled up. Get nervous.
【0015】 このとき、ラチェット爪車12にラチェット爪13が係合してドラム6は逆転 が阻止されているので、係止部8は降下せず、下位のネット1は緊張状態に保た れる。 上位のネット1は係止部8の上昇分だけたるむことになるが、上位ネット1の 上方に配置した緊張装置2で上記と同様に引上げることによってたるみを吸収し 、上方へ順送りで緊張させればよい。At this time, since the ratchet claw 13 is engaged with the ratchet claw wheel 12 and the reverse rotation of the drum 6 is prevented, the locking portion 8 does not descend and the lower net 1 is kept in a tensioned state. .. Although the upper net 1 will be slackened by the amount by which the locking portion 8 is raised, the tension device 2 arranged above the upper net 1 pulls it up in the same manner as described above to absorb the slack and tension it in the upward direction. Just do it.
【0016】 逆に、ネット1を取外す場合は、レバー14を回し、ラチェット爪車12に対 するラチェット爪13の係合を解除すればよく、ドラム6の逆転で係止部8は降 下し、ネット1が緩むので、有頭ピン16からはと目17を外すことができる。On the contrary, when the net 1 is to be removed, the lever 14 may be rotated to release the engagement of the ratchet pawl 13 with the ratchet pawl wheel 12, and the engaging portion 8 is lowered by the reverse rotation of the drum 6. Since the net 1 is loosened, the eye 17 can be removed from the headed pin 16.
【0017】 なお、係止部8は図示に限らず、上下二枚のネット1を緊張させる場合、プレ ート15の片側の上下にのみ有頭ピン16を設けたものでもよい。Note that the locking portion 8 is not limited to the one shown in the figure, and when the upper and lower nets 1 are to be tensioned, headed pins 16 may be provided only on the upper and lower sides of one side of the plate 15.
【0018】[0018]
