[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold fixing device for fixing a temporary scaffold used on a temporary scaffold at a construction site or the like.

[0002]

2. Description of the Related Art Conventionally, a scaffold at a construction site or the like is assembled through a process of forming a work floor by arranging a scaffold with pipe materials and arranging a scaffold plate between pipes at lateral positions. In such a scaffold, it is necessary to fix the scaffold plate to ensure safety.

Conventional scaffold plate fixing means ties the scaffold plate to a pipe with a wire (iron wire), twists both ends of the wound wire, cuts off the excess length, and bends the tip so as not to disturb. ing.

[0004]

However, in the above-mentioned prior art, when removing the scaffold plate, the wire is cut with a cutter, the wire entangled with a pipe or the like is removed, and the cut debris are collectively cleared. There is a problem that requires work and takes a lot of labor and time. In addition, since wires cannot be reused, costs are increased.

An object of the present invention was made in view of the state of the art, and it is an object of the present invention to provide a scaffold fixing device which is quick, safe, easy and reusable.

[0006]

In order to achieve the above-mentioned object, the present invention provides a bar-shaped body for holding a scaffold plate.
A horseshoe-shaped clamper that fits almost half of the pipe,
Pin-coupled to the clamper and fits under the scaffold pipe

The clamp lever is formed in a J-shape to
The horseshoe-shaped part that can be fitted to the lower part of the
An end is provided, and the part connected from this outer end to the horseshoe-shaped part is clicked.
Pin to one end of the lamp
At the tightening position of the scaffold pipe by rotating the lever,
It provided the ends and overlapping possible projections in the clamper, and a so that provided the insertable ring to said projections the movement is freely fitted on the outer end of the clamping lever.

[0007]

According to the above-described means, the clamper provided on the holding plate spring is fitted on the upper part of the scaffold pipe, and the clamp lever attached to the clamper is rotated to tighten the clamp from below the scaffold pipe. The scaffold pipe can be securely held by fixing the protrusion of the clamper and the outer end of the clamp lever with a ring. Therefore, it is possible to provide a scaffold plate fixing device that is quick, safe, easy and reusable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the scaffold fixing device according to the present invention, FIG. 2 is a perspective view, and FIG. 3 is a front view showing a state at the time of disassembly. FIG. 4 is a side view showing a state at the time of mounting, and FIG. 5 is a plan view showing an engaging portion between adjacent members.

The scaffold is formed by arranging the scaffold pipes vertically and horizontally and screwing the intersections with fixing brackets (not shown) to form a framework.
Is placed. In this state, as shown in FIG. 2, the holding plate spring 14 is placed on the scaffold plate 12 so as to overlap the scaffold pipe 10. The holding plate spring 14 has a horseshoe-shaped clamper 16 fitted to the peripheral surface of the scaffolding pipe 10 at one end of a band-shaped main body, and has a ring-shaped hook 18 at the other end. The clamper 16 has a protrusion 20 on one side, and a pin 22 is provided on one end of the horseshoe-shaped leg.

A clamp lever 24 having a horseshoe-shaped grip having the same inner diameter as the clamper 16 is attached to the clamper 16 with a pin 22 as an axis. At one end of the clamp lever 24, a pull ring 26 having a hole into which a finger can be inserted is provided, and a ring 28 is movably fitted near the pull ring 26. The clamp lever 24 rotates about the pin 22 in the left-right direction in the figure.

Next, the attachment / detachment of the scaffold plate fixture having the above-described configuration will be described. When attaching the scaffolding fixture,
The holding plate spring 14 is placed on the scaffold pipe 10 while the pull ring 26 is pulled down and the ring 28 is positioned near the pull ring 26, as shown in FIG. Place. The holding plate spring 14 is pressed down so that the horseshoe-shaped portion of the clamper 16 is fitted into the scaffold pipe 10, and then the pull ring 26 is pulled upward to rotate the clamp lever 24 as shown in FIG. 24 a is positioned on the lower surface of the scaffold pipe 10, and the pipe 10 is gripped by the clamper 16 and the clamp lever 24. At this time, since there is a gap 32 between the lower surface of the clamper 16 and the upper surface of the scaffold pipe 10, the clamp lever 24
Functions to tighten the scaffold pipe 10. In this state, the ring 28 is moved so as to fit into the projection 20, and the clamper 16 and the clamp lever 24 are fixed.

The opposite side of the holding plate spring 14 is shown in FIG.
As shown in FIG. 5, the tip of the hook 18 is inserted into an insertion opening 30 provided inside the upper part of the clamper of the adjacent pressing leaf spring 14 to connect the two pressing leaf springs 14.

[0014]

[Effects of the Invention] As is clear from the above, according to the present invention , the scaffold pipe is almost attached to the bar-shaped main body that holds the scaffold plate.
A horseshoe-shaped clamper that fits in half and a clamp
Clamps that can be fitted to the lower part of the scaffold pipe
A scaffold fixing provided with a lever,
Form a lever into a J-shape and fit under the scaffold pipe
Provide a possible horseshoe-shaped part and an outer end with one end extended,
Connect the part from the outer end to the horseshoe-shaped part with one end of the clamper.
To the clamp lever, and rotate the clamp lever.
Laminated with the outer end at the tightening position of the scaffold pipe
The possible projection provided on the clamper, since the so that provided the insertable ring to said projections the movement is freely fitted on the outer end portion of the clamp lever, quickly, safely and easily installed and removed In addition to this, it can be used repeatedly and does not increase the cost. It is also easy to manufacture. Furthermore, since the clamp lever has a J-shape, the scaffold pipe can be strongly tightened by levering the outer end, and the portion connecting the outer end of the clamp lever to the horseshoe-shaped portion is pin-connected to the clamper. Because of this, even if the scaffold plate and the scaffold pipe are separated by a considerable amount, there is an effect that the scaffold can be fastened with one touch.
