Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a main rope attachment bracket that allows a main rope to be conveniently stretched over a folded roof.

[Background technology]

When performing work at heights such as roofing work on folded roofs, painting work, and waterproofing work, it is desirable to equip workers with a life line to prevent them from falling. However, conventionally, it has been difficult to stretch the main rope that connects the lifeline, and there has been a need for a main rope attachment fitting that can conveniently tension the main rope.

[Purpose of invention]

The present invention is installed using the bolts of the bracket for supporting the folded roof, and the main rope can be conveniently spanned.
The purpose of this invention is to provide a main rope attachment fitting that can meet the above requirements.

[Disclosure of invention]

An embodiment of the present invention will be described below based on the drawings. In the figure, the main rope attachment bracket 1 is attached to the folded roof 2.
An upright piece 6 is provided on the base piece 5 that is fixed using the bolts 4 of the support bracket 3, and a hole 9A for locking the master rope 7 is provided in the base piece 5 and the upright piece 6. ,9
B is provided.

The folded roof 2 is constructed by, for example, alternately mountain-folding and valley-folding a rope plate to form a mountain portion 10 extending in the flow direction.
... forms a valley 11..., and the upper and lower ends are overlapped on the main building 13, and between the main building 13...,
It spans between the main building 13 and the ridgepole, and the folded roof 2
... forms a gable roof in this example.

In this example, the main building 13 is made of a channel-shaped rope, and a receiving metal fitting 3 that is bent along the lower surface of the folded roof 2 is fixed to the upper surface of the main building 13 by, for example, welding. Further, the bolt 4 is provided to protrude from the upper end of the protrusion 15 along the lower surface of the crest 10 of the receiving fitting 3. Note that the bolt 4 is fixed by welding its head to the lower surface of the protrusion 15. In addition, the bolt 4 is inserted into the through hole 2 bored in the peak part 10 of the folded roof 2.
1 and protrudes from the upper surface of the peak portion 10 of the folded roof 2 at the same interval as the peak pitch. Further, a cap nut 23 is screwed onto the protrusion 22 of the bolt 4, and the folded roof 2 can be fixed to the main building 13 by tightening the cap nut 23.

In this example, the base piece 5 is made of a rectangular steel plate having a strip shape, and has a plurality of through holes 12 formed therein. The through holes 12 are arranged in the longitudinal direction of the base piece 5 at the same intervals as the peak pitches of the folded roof 2 in the base piece 5 in this example.
Perforations are made at both ends and in the center.

Further, on one side edge of the base piece 5, a rising piece 6 having the same shape as the base piece 5 and having a rectangular shape is provided upright.

Also, a master rope 7 is installed at the intermediate position between the through holes 12, 12 of the base piece 5.
Holes 9A, 9A for locking, and holes 9B, 9B are provided at both ends of the upright piece 6.

The main rope 7 also has locking fittings 25, which are carabiners in this example, which lock into the holes 9A and 9B at both ends thereof, and an adjustment tool 26 at one end so that the length can be arbitrarily adjusted. sell.

[Effect]

However, the base piece 5 has the folded roof 2 in the through hole 12...
The protruding parts 22 of the bolts 4 which protrude through the peaks 10 can be inserted, and can be bridged between the peaks 10 by straddling the valleys 11 of the folded roof 2. Therefore, the nuts 24 can be used to bolt the folded roofs 2 and 2 to the receiving bracket 3.

Further, by fixing the base piece 5, the hole 9A can be located at the center of the valley 11 of the folded roof 2.

Further, the upright piece 6 protrudes from the upper surface of the folded roof 2 at a right angle.

Therefore, the holes 9A and 9B are the locking fittings 2 of the main rope 7.
5 can be locked.

As illustrated in Fig. 2, the main rope attachment fittings 1 are attached to both sides of the eaves and both sides of the ridge, and the main rope 7A in the flow direction of the folded roof 2 is stretched between the holes 9A and 9A. Main rope 7B in a direction transverse to the flow direction
is stretched between the holes 9B and 9B of the rising piece 6.

Further, each of the main ropes 7A, 7B is adjusted in length and tensioned by an adjustment tool 26. Also, on main ropes 7A and 7B,
A carabiner 31 is provided at one end of the lifeline 30 extending from the safety belt 29 worn by the worker.
Connect by.

[Effect of idea]

As mentioned above, the main rope mounting bracket of the present invention has through holes formed at the same intervals as the peak pitches of the folded roof, and the bolts of the receiving bracket that pass through the peaks of the folded roof and pass through the holes. In addition to providing an upright piece on the base to be fixed using the base piece, a hole for locking the main rope is provided at a position approximately in the middle of the through hole of the base piece and on the upright piece. It can be fixed from the top of the roof, and the main rope can be easily stretched, improving work safety.
Furthermore, since the base piece is fixed to a receiving metal fitting for supporting the folded roof, the main rope can be firmly fixed. Furthermore, a master rope to be stretched in the direction of flow of the folded roof is secured to a hole provided in the base piece, and a master rope to be stretched in a direction transverse to the flow direction is secured to a hole provided in the upright piece. By locking, the impact force applied to the bolt due to a worker slipping, falling, etc. acts mainly in the shearing direction of the bolt, thereby preventing the bolt from breaking, etc., and further improving safety. It can have many effects.

In addition, in the main rope attachment bracket of the present invention, when the upright piece 6 is made into a strip shape having the same shape as the base piece 5 as in this embodiment, the upright piece 6 should be provided with a through hole 12 to have a symmetrical shape. You can also do it.
