Description

[Detailed description of the invention] "Industrial field of application" This invention relates to the provision of supporting metal fittings for main ropes that are erected on struts.

``Prior Art'' As shown in the site diagram of a heap shoring work in FIG. 2, a main line 2 is stretched over a strut 1 to ensure the safety of workers walking on the strut.

In addition, in the figure, 3 is H steel pile, 4 is sheet pile, 5 is upright,
Reference numeral 6 indicates a flat corner hardware, 7 indicates a flint material, 8 indicates a free piece for a flint support, 9 indicates a triaxial piece, 10 indicates a gusset plate, 11 indicates a coaxial piece, and the main rope 2
is a post metal fitting 12 erected on the side edge of the strut 1.
This is something that is strung up between the two.

As the conventional support hardware 12, the third
As shown in the figure.

That is, the upper and lower flanges 1 of the strut H-shaped steel 13
A pipe 14 is attached to the pipes 3a and 13b via a plate and a clamp 15 for connecting the pipes, and the master rope is inserted through a ring 14a for passing the master rope provided at the upper end of the pipe 14.

``Problems that the invention attempts to solve'' However, such support hardware is as listed below.
It has various drawbacks.

There are many parts to be assembled, making management cumbersome.

There is work to attach and detach the lower flange 13b,
Extremely dangerous.

Many fastening operations are performed in unnatural postures, making installation time-consuming.

``Means for solving problems'' and ``effects'' This proposal was made in view of the above circumstances, and its gist is that a rectangular pipe with a ring section attached to the upper end for passing the main rope through is It is erected integrally on one side of the plate, and symmetrically, on the lower surface of the plate, the length is longer than the distance between the upper and lower flanges of the H-shaped steel, and the upper and lower flanges of the H-shaped steel are perforated. A rod with a diameter that fits loosely into the bolt fastening hole is integrally provided, and a short rod for penetrating only the upper flange is integrated on the lower surface of the rectangular plate on the other side, so that the number of parts is only one,
There is no need to work on the underside of the H-shaped steel flange.
The present invention provides a new support hardware that can be installed by simply dropping it in and removed by simply pulling it out.

``Example'' This will be described in detail below based on example diagrams.

Figures 1a, b, and c are plan, front, and partial side views of one embodiment of the prop hardware of the present invention. In the figures, 16 is a pipe as a support that stands at a predetermined height on the strut, and the upper end of the pipe is A steel rod 17 curved in a U-shape is welded by clamping its legs, and a ring portion 1 for inserting the main rope is formed by a crossbeam 18 installed between the legs of the steel rod 17.
9 is formed.

The lower end of the pipe 16 is a rectangular plate 20
It is welded to one side.

A rod 21 is integrally suspended from the lower surface of the plate 20 symmetrical to the pipe 16 by penetrating through the hole and welding. The rod 21 is a strut H
Existing bolt fastening holes 22, which have a length equal to or longer than the distance between the upper and lower flanges 13a and 13b of the molded steel, and are aligned vertically with the upper and lower flanges 13a and 13b in advance;
It must have a diameter that fits loosely into 22. Furthermore, a short rod 24 for penetrating only the upper flange 13a is integrally provided on the lower surface of the rectangular plate 20 on the other side.

For example, if the rod 21 is dropped into the bolt fastening hole 22 while holding the ring part 19,
The plate 20 is hooked to the upper flange 13a, and the pipe 16 stands on the strut.

The pipe 16 has a rod 21 that extends downward and passes between the upper and lower flanges 13a and 13b, and a rod 24 that passes through the upper flange 13a, so that it is added laterally when the main rope is stretched. It is designed to be able to stand firmly with both feet against external forces, and also has the function of preventing rotation by restraining both feet.
This eliminates the needless rotation of the pipe 16.

To remove the support, simply pull up the pipe 16.

In the illustrated example, a movable slip-off prevention pin 23 is inserted into the tip of the rod 21 to prevent the attachment rod from coming off.

"Effects of the invention" The proposed product with the above structure has the following effects.

Since only one member is required and no separate members such as clamps are required, it is suitable for maintenance management.

It is extremely safe because there is no need to reach the lower surface of the lower flange of the H-beam strut (if the pull-out prevention pin 23 is installed, it is only needed when pulling it out).

Installation and removal work is simple and quick, simply dropping and pulling up.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A pipe with a ring for passing through the main rope at its upper end is integrally erected on one side of a rectangular plate, and a cut is made symmetrically to the lower surface of the plate. A rod having a length longer than the length between the upper and lower flanges of the H-shaped steel beam and having a diameter that loosely fits into bolt fastening holes drilled in the upper and lower flanges of the H-shaped steel is integrally provided, and the rectangular plate plate A support metal fitting for a main rope, characterized in that a short rod for penetrating only the upper flange is integrally provided on the lower surface of the main rope on the other side. (2) The metal support for the main rope as set forth in Claim 1 of the Utility Model Registration Claim, which is equipped with a movable pull-out prevention pin at the tip of the rod.
