Description

[Detailed description of the invention] (Field of industrial application) This invention is a method for slinging members at high places such as girders and beams of houses under construction by one person from the ground. It relates to slinging equipment.

(Conventional technology) When constructing a new house, it is necessary to make the front and rear, left and right inclinations of the pillars vertical. The eyewire ropes at both ends of the rope were pulled by a hand-operated traction device to maintain the vertical position. However, in order to sling girders, beams, etc. at high places, workers must climb a ladder or stepladder to perform the sling work, which poses problems such as the risk of falling accidents and poor work efficiency. It was hot.

(Purpose of the invention) The present invention has been completed with the aim of solving these conventional problems and creating a tool for slinging at high places that can be carried out by one person from the ground.

(Structure of the invention) The present invention attaches a hook hook fitting that contacts a girder, beam, etc. at a high place to the upper end of a support rod made of multiple extensible and contractible pipes via a spring.
A wire rope is inserted into the support rod by passing through the spring at the upper end of the support rod and the inside of the hook hook fitting, and a hook is attached to the upper end of the wire rope exposed from the hook hook fitting, and a hook is inserted from the lower end of the support rod. This is characterized in that an engaging portion for traction is attached to the exposed lower end of the wire rope, and will be described in detail below with reference to illustrated embodiments.

(Example) In the figure, 1 is a long support rod consisting of multiple pipes 2 and 3 that are combined like a telescope tube so that they can expand and contract, and they are fixed together with pipe 2 pulled out from pipe 3. However, when compressive force is applied in the pulled out state, the pipes 2 and 3 can contract so that they overlap.

At the upper end of such a support rod 1, a high girder 20,
An oval ring-shaped hook hook 4 for contacting the beam 21 etc. is elastically attached via a spring 5. Further, inside the support rod 1, a wire rope 8 having a hook 6 at the upper end and an engaging portion 7 for pulling at the lower end connects the hook 6 and the engaging portion 7 to the support rod 1.
It is inserted and exposed from both the top and bottom ends. The upper end of the wire rope 8 passes through the spring 5 at the upper end of the support pole 1 and the inside of the hook hook 4, and a hook 6 is attached to the upper end of the hook hook 4 exposed above. Although the engaging portion 7 is made by bending the lower end of the wire rope 8 into a loop shape and processing it to prevent compression, the present invention is not limited to this.

The length of the wire rope 8 is such that even when the support rod 1 is extended to the maximum, the hook 6 and the engaging portion 7 still come out from both the upper and lower ends of the support rod, and as shown in FIG. A stopper 9 may be attached. In addition, although the pipes 2 and 3 constituting the support rod 1 are double pipes inside and outside in the embodiment, three or more pipes can also be used. It is preferable that the ends of each pipe be treated to prevent them from coming off, or that the entire pipe be tapered to prevent the pipes from separating from each other.

(Function) With this structure, the support rod 1 consisting of multiple expandable and contractible pipes 2 and 3 is stretched, the lower end of the wire rope 8 is pulled below the support rod 1, and the lower part of the support rod 1 is pulled by hand. Hold it with a support pole 1
The upper end is made to go over the girder 20, beam 21, etc. at a high place. Next, the hook hook 4 attached to the upper end of the support rod 1 via the spring 5 is attached to the girder 20 and the beam 2.
When a compressive force in the axial direction is applied to the support rod 1 by pressing it against the side of the first pipe, the engagement between the pipes 2 and 3 is disengaged, and the upper pipe 2 is caused to fall downward so that it overlaps with the pipe 3. can.

By shortening the entire length of the support rod 1 in this way, the wire rope 8 inserted inside the support rod 1 is
can be loosened and let out, and the hook 6 at the tip of the wire rope 8 can be suspended from behind the girder 20, beam 21, etc. at a high place to near the ground. Also, when the upper pipe 2 is dropped to your hand in this way, the hook hook 4 at the upper end of the pipe 2
Since the height is within reach, the hook 6 at the upper end of the wire rope 8 hanging from the rear of the girder 20, beam 21, etc. at a high place is manually hooked onto the hook hook 4 as shown in FIG.

After that, when the wire rope 8 is pulled downward, the pipe 2 is drawn out from the pipe 3 again by being pulled by the hook hook 4, and the loop between the hook 6 and the hook hook 4 becomes smaller, as shown in FIG. The tip of the wire rope 8 is wrapped around the girder 20, beam 21, etc., as shown in FIG. Therefore, if the engaging part 7 for pulling at the lower end of the wire rope 8 is connected to the eye wire rope 19 at both ends wound around the base 22 via the pulling tool 10 and the pulling tool 10 is operated, tension is applied to the wire rope 8. This function allows the inclination of the column 23 to be corrected vertically.

In addition, while this operation is being performed, the support rod 1
is swung up and down to some extent, but since the hook hanging bracket 4 is elastically attached to the upper end of the support rod 1 via a spring 5, the hook hanging bracket 4 does not move around the girder 20 or Even when the support rod 1 is fixed to the beam 21 or the like, the support rod 1 can be swung to some extent without causing any trouble in its handling.

(Effects of the invention) As is clear from the above explanation, the present invention allows one person to perform sling work on girders, beams, etc. at high places from the ground, and prevents the risk of falling accidents. Since it is possible to improve work efficiency, it has great practical value as a tool for slinging to high places that solves the problems of conventional sling work.
