However, in the conventional single tube clamp, when used in the orientation shown in FIG. Therefore, when tightening the fastening nut K, the hand must be stretched around the fastening nut K side, which makes it difficult to tighten the fastening nut K. In addition, since the hand is extended away from the operator, it is easy for the operator to lose his or her posture, and there is a risk that the operator may fall or fall.

The present invention has been made in view of the above circumstances, and the problem to be solved is that it is easier to tighten the fastening nut compared to the conventional single pipe clamp, and the worker can work in a stable posture. To provide a tube clamp.

The single pipe clamp of the present invention comprises a fixing part having a recess for accommodating a pipe, an opening/closing piece that covers the outside of the pipe in the recess and presses the pipe, and a threaded rod with a nut that fixes the fixing part and the opening/closing piece. An open/close piece is rotatably provided on one end side of the fixed part, a screw rod with a nut is rotatably provided on the free end side of the open/close piece, and the other end side of the fixed part is provided with an engaging portion for engaging the nut-equipped screw rod.

In the single tube clamp of the present invention, a threaded rod with a nut is provided on the free end side of the opening and closing piece so that the fastening nut is positioned on the operator side, so when used in the orientation shown in FIG. However, it is easy to fasten the fastening nut. In addition, unlike conventional single tube clamps, there is no need to extend the hand around the fastening nut side, so the operator is less likely to lose his posture and is safe.

TECHNICAL FIELD The present invention relates to supports used for assembling scaffolds and attaching supports to scaffolds.

Single-tube clamps are used to assemble the scaffold and attach posts to the scaffold. Single tube clamps include single clamps that can clamp and hold one single tube with one clamp ( tightening tool), as well as two single clamps that are connected to clamp and hold two single tubes. There are orthogonal clamps, universal clamps, and triple clamps in which three single clamps are connected to clamp and hold three single pipes (for example, Patent Document 1). These clamps are hereinafter sometimes referred to as single tube clamps because they are clamps capable of clamping and holding a single tube.

The single clamp has a fixed part with a recess for receiving a pipe, an open/close piece rotatably provided at one end of the fixed part, and a threaded rod with a nut provided at the other end of the fixed part. . This type of fastener can hold the pipe by covering the outside of the pipe accommodated in the recess with an opening/closing piece and fixing the opening/closing piece to a fixing portion with a screw rod with a nut.
