Description

[Detailed Description of the Invention] The present invention relates to a single-pipe suspended scaffolding handrail hardware.

Single pipe suspended scaffolding is already well known as a type of steel pipe scaffolding, but in this single pipe suspended scaffolding,
When attaching a handrail, a two-way orthogonal clamp is usually used, and one side of the clamp is fastened to the hanging scaffold main pipe, and the other side is fastened and fixed to the handrail construction pipe.

However, in this case, when a force is applied outward or inward to the handrail and a rotational force is applied from the handrail construction pipe to the orthogonal clamp, slip rotation occurs on the side of the suspended scaffolding main pipe of the clamp, Since the handrail falls down, it is necessary to take measures to prevent the handrail from falling, such as incorporating auxiliary materials to prevent the handrail from falling or taking a stand, which requires a considerable amount of effort and is unnecessary for assembly.

The present invention seeks to eliminate such conventional drawbacks.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

FIG. 1 shows a first embodiment of the present invention, in which two fastening metal fittings 1 and 2 and a groove-shaped metal fitting 3 are joined in three orthogonal directions by welding 4 .
Further, a sheath pipe 5 is connected to one of the fastening hardware 1 by welding 4.

The fastening hardware 1, 2 pivots one end of a movable member 12, 22, which is curved both inside and outside, to one end of an L-shaped fixed member 11, 21, which is curved on the inside and flat on the outside. Also, the fixing member 11,
At the other end of 21, screw rods 15, 25 with nuts 14, 24 screwed together are pivotally attached 16, 26, and the movable member 1
The other ends of the fixing members 11 and 22 are formed with bifurcated engaging portions 17 and 27 that engage with the threaded rods 15 and 25, and the back surfaces of the fixing members 11 and 21 are joined to the groove-shaped hardware 3.

The groove-shaped hardware 3 is formed to have a groove width equivalent to the inner diameter of the fastening hardware 1 and 2, with the opening surface facing outward and horizontally, and the groove direction being horizontal, and perpendicular to the fastening hardware 1 and 2, respectively. It is joined to fastening hardware 1 and 2. Further, a bolt 31 is threaded through the groove wall at a proper position.

The sheath pipe 5 has an inner diameter that is approximately the same as the inner diameter of the fastening hardware 1 and 2, and has its mouth top surface connected to one of the fastening hardware 1 in the vertical direction, and has a half surface connected to the fixing member 11 of the fastening hardware. It is joined to.

The configuration is as shown above, and when assembling, first,
Fit the channel-shaped hardware 3 to the hanging scaffold main pipe A, tighten the bolt 31, then fasten the fastening hardware 2 perpendicular to the channel-shaped hardware in the horizontal direction to the hanging scaffold child pipe B, and finally, install the handrail. The lower end of the base pipe C is inserted into the sheath pipe 5 from above to temporarily support it, and the vertical fastening hardware 1 is fastened to the handrail construction pipe C.

In order to fasten the fastening hardware 1 and 2, the movable member 1
2, 22 to the two-pronged engaging portions 17, 27 of the screw rod 15,
25 and tighten the nuts 14, 24.

Note that the sheath pipe 5 is provided to prevent the handrail construction pipe from falling, since assembly work is often performed at high places. If the joint strength is weak, a splint may be added.

FIG. 2 shows a second embodiment, in which the positions of the other fastening hardware 2 and the groove-shaped hardware 3 are exchanged in the previous example. Therefore, one fastening hardware 1 and the other fastening hardware 2 are fixed by the fixing member 11,
12, the fixing member 11 of one fastening hardware 1 and the groove-shaped hardware 3 are connected to each other by welding 4.
They are joined by welding 4 via a shaped auxiliary metal fitting 5, and the grooved metal fitting 3 is disposed horizontally in the groove direction with the opening surface facing upward.

In this case, due to the above relationship, the other fastening hardware 2
is attached to the scaffolding main pipe A, and the groove-shaped metal fittings 3 are attached to the hanging scaffolding child pipe B. The rest is the same as the previous example.

According to the present invention, it is possible to restrain in three directions, prevent rotation, reliably prevent the handrail construction pipe from falling down, and therefore the handrail from falling down, and use other methods to prevent falling, such as incorporating auxiliary materials or taking restraints. In addition, it is easy to assemble, requires less labor, and can be carried out safely even when assembling at high places.Furthermore, not only the handrails but also the suspended scaffolding itself can be assembled in one go, reducing costs. , which is extremely useful in practice.
