Abstract

PURPOSE:To provide a safety band attachment for easily surely mounting a safety band to work members such as wide width H-steel beam, members projecting from wall surfaces, etc., in a height operation-accompanying building works, electric works, etc. CONSTITUTION:A bolt 5 penetrating the upperside horizontal part 2 of a nearly U-shaped member 1 is screwed in this part and the upper part of a nearly U-shaped member 10 is connected pivotably to the nearly U-shaped member 1. An annular member 11 is attachably inserted in the nearly U-shaped member 10.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a safety belt attachment device for attaching a safety belt to construction members such as wide H steel and wall protruding members during high-altitude work associated with construction work, electrical work, etc. .

0002

[Prior Art] When working at heights, it is mandatory to use a safety belt along with a helmet to ensure the safety of workers. Since there are no safety belts, safety belts are generally used by wrapping them around construction materials.

0003

[Problem to be Solved by the Invention] However, as construction materials become larger, it is not only difficult to wrap the safety belt around the construction materials, but also the work of wrapping the safety belt around the construction materials itself is dangerous. It is occurring. Furthermore, when a safety belt is used wrapped around a construction member, there is a risk that the safety belt may loosen or slip during work at high places.

0004

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a structure in which a bolt is screwed into the upper horizontal part of the substantially U-shaped member and extends vertically through the upper horizontal part. The present invention provides a safety belt attachment device characterized in that the upper part of a substantially U-shaped member is pivotally attached to the substantially U-shaped member, and an annular member is fitted into the substantially U-shaped member.

[0005]

[Operation] When attaching a safety belt to a construction member using the safety belt attachment tool of the present invention, first attach the safety belt attachment tool to the construction member. That is, by fitting the approximately U-shaped member of the safety belt attachment device onto the construction member, and tightening the bolt screwed onto the upper horizontal portion of the approximately U-shaped member, the tip of the bolt is brought into pressure contact with the surface of the construction member. The substantially U-shaped member is fixed to a construction member. In this state, the approximately U-shaped member strongly holds the construction member between the tip of the bolt and the lower horizontal part of the approximately U-shaped member, so the approximately U-shaped member strongly holds the construction member between the tip of the bolt and the lower horizontal part of the approximately U-shaped member. Fixed. After that, the safety belt is attached to the annular member. When attaching the safety belt to the annular member, the safety belt may be hung over the annular member as shown in Fig. 2, but as shown in Fig. may be locked to the annular member. When the safety belt is attached to the annular member in this manner, the load applied to the safety belt is transmitted to the construction member via the annular member, the substantially U-shaped member, and the substantially U-shaped member. At this time, the substantially U-shaped member is rotatable in a predetermined direction relative to the substantially U-shaped member, and the annular member is freely rotatable relative to the substantially U-shaped member in a direction perpendicular to the direction. No unreasonable force is applied between the substantially U-shaped member and the annular member.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 indicates a substantially U-shaped member. Roughly U-shaped member 1
The upper horizontal part 2, the vertical part 3, and the lower horizontal part 4 are integrally formed in a U-shape. A bolt 5 passing vertically through the upper horizontal part 2 is screwed into the upper horizontal part 2 of the substantially U-shaped member 1. 6 is a turning rod for rotating the bolt 5. It is desirable that the bolt 5 has a concave portion 8 at its tip so that the tip can bite into the surface of the construction member 7 and prevent slippage (see FIG. 2). Reference numeral 9 denotes an anti-slip material attached to the upper surface of the lower horizontal portion 4. For example, the upper part of the substantially U-shaped member 10 is pivotally attached to the lower horizontal portion 4 of the substantially U-shaped member 1, so that the substantially U-shaped member 10 can freely rotate in the direction of the arrow in FIG. . 10' is a substantially U-shaped member 10
It is the pivot of The substantially U-shaped member 10 includes an annular member 11
can be fitted. The annular member 11 is arranged in a direction perpendicular to the above-mentioned direction with respect to the substantially U-shaped member 10 ((direction shown by the arrow in FIG. 3)).
It can be rotated freely. 12 is a safety belt, 13 is the safety belt 12
A lock attached to one end of the In the safety belt attachment device of the present invention, tools and materials may be suspended from the annular member 11, or a pulley may be attached to the annular member 11 to hoist relatively light objects.

[0007]

[Effects of the Invention] As explained above, the safety belt attachment device of the present invention can be easily and reliably fixed to a construction member by tightening the bolt screwed onto the upper horizontal portion of the substantially U-shaped member. It is also extremely easy to attach a safety belt to the annular member. Further, since the substantially U-shaped member is rotatable in a predetermined direction relative to the substantially U-shaped member, and the annular member is freely rotatable relative to the substantially U-shaped member in a direction perpendicular to the direction, No unreasonable force is applied between the U-shaped member and the annular member. As described above, according to the present invention, safety belts can be attached extremely easily and reliably to construction members such as wide H steel and wall protruding members during high-place work associated with construction work, electrical work, etc. Work safety is significantly improved.
