Description

  The present invention relates to a safety holder and a main rope tensioning structure used for the purpose of preventing an operator from falling down in inspection of a roof and a roof material.

  In general, a lifeline is attached for the purpose of preventing the operator from falling during inspection, repairing of the roof, installation work of the television antenna, and the like. When attaching the lifeline, first, the master rope is stretched on the building, and then one end of the lifeline is connected to the master rope and the other end is attached to the waist of the operator. In this way, the lifeline is connected to the building via the master line. Therefore, in order to prevent the operator from falling, it is extremely important to fix the master rope firmly to the building.

  As a conventional method of laying a master rope, for example, a master rope with hook metal fittings attached to both ends is prepared, and hook metal fittings are locked to the eaves on both sides of the ridge, and the master rope is straddled from one eave to the ridge. There is a method of stretching across the eaves on the opposite side. By this method, it is possible to ensure safety while securing the movable range of the worker.

  Another method is to use a weight bucket instead of the hook metal fitting. The weight bucket is mainly composed of a container for storing water and a connecting portion connected to one end of the master rope. When using this weight bucket, first, a hook fitting provided at one end of the master rope is fixed to the eaves. Next, a weight bucket storing water is placed on the eaves side opposite to the eaves to which the hook metal fittings are fixed, and the other end of the master rope is connected to the connection part of the weight bucket. As a result, both ends of the master rope are fixed to the eaves and the ground on the opposite side of the eaves, and the master rope extends in the direction of the eaves ridge and is firmly stretched along the roof.

  By the way, in the above-described method of stretching the master rope using the hook metal fittings and the weight bucket, the hook metal fittings must be attached to the eaves. Therefore, the following parent rope construction method has also been proposed.

  That is, in Patent Document 1, a pair of safety fittings are spaced in the ridge direction and fixed with a screw or the like, and one end of the master rope is fastened to one safety fitting and the other end is attached to the wrapping. A method is disclosed in which the master rope is stretched so as to extend in the ridge direction by fastening to the other safety fitting. In this method, since the work is performed in the ridge portion that is less likely to fall than the eaves, the worker can perform the tensioning work safely.

  Patent Document 2 discloses a method of attaching a safety metal fitting on the roof material so as to sandwich the top of the ridge in the ridge. When fixing the safety bracket, cover the headboard and ridge cover from above, and drive in fixing tools such as screws and nails. In this method, the safety bracket is hidden by the ridge cover, so that the appearance of the roof is not impaired. In addition, there is no need to remove the safety fitting, and the work that may fall is reduced.

  However, the above-described parent rope tensioning method using the hook fitting and the weight bucket has a problem that it takes time to attach the hook fitting to the eaves.

  Moreover, in the parent rope tensioning method disclosed in Patent Documents 1 and 2, it is necessary to wrap the safety bracket, and to fix the fixture by driving a fixture such as a screw into the baseboard or purlin. For this reason, there is a problem that it takes time to install the safety fitting and requires permission from the owner.

  The present invention has been made in view of the above points, and an object of the present invention is to enable a safety holder for holding safety means such as a lifeline to be easily and safely installed on a roof.

  In order to achieve the above object, the present invention devised the shape of a safety holder for holding safety means such as a lifeline so that it can be easily and safely installed on a roof.

And means.

  According to a second invention, in the first invention, each of the roofing materials is formed by arranging a plurality of roof members adjacent to each other in a direction intersecting with the eaves-ridge direction, and the protruding piece includes the base Is inserted into the overlapped portion and protrudes from the gap between the roof members.

  According to a third invention, in the first or second invention, each of the roofing materials is formed with a slit that opens at an eave side end and extends toward the ridge side, and the protruding piece has the base It is configured to protrude from the slit while being inserted into the overlapping portion.

  According to a fourth invention, in any one of the first to third inventions, the holding means is constituted by the protruding piece in which a holding hole for holding the safety means is formed.

  The fifth invention is characterized in that, in the fourth invention, a protective member for protecting the safety means is attached to a peripheral edge portion of the holding hole.

  According to a sixth aspect of the present invention, there is provided a master rope tensioning structure in which the safety retainer in any one of the first to fifth inventions is fixed to the roofs on both sides of the ridge, and the master rope is stretched by the pair of safety retainers. The following solution was taken.

  That is, according to the sixth aspect of the present invention, the base of one of the safety holders is inserted into the overlapping portion of the one roof, and the base of the other safety holder is inserted into the overlapping portion of the other roof, A part of the master rope is held by the one safety holder and the other part of the parent rope is held by the other safety holder, and the master rope straddles the one ridge from the one safety holder. And is stretched over the other safety holder.

  According to the first invention, first, the base is inserted into the overlapping portion of the roof material provided in the eaves-ridge direction, and then the holding means holds safety means such as a lifeline. Then, when the worker connected to the safety holder through the safety means works on the ridge side with respect to the safety holder, the safety holder moves to the ridge side, and the protruding piece forms the overlapping portion. It touches the roof material on the ridge side. Accordingly, the base of the safety holder is pressed against the roof base side by the roof material on the ridge side, and the protruding piece comes into contact with the roof material on the ridge side, so that the safety holder is firmly fixed at that position. Therefore, the worker can work safely. Furthermore, since the safety holder is fixed to a safe place on the ridge side of the eaves, the safety holder can be installed more safely than before.

  Moreover, according to 1st invention, since a safety holder is only inserted in the overlap part of the roof material erected in the eaves-ridge direction, a safety holder can be installed more easily than before.

  The base may be inserted into the overlapping portion after the safety means is held by the holding means.

  According to the second invention, the safety holder can be installed on the roof using the gaps between the plurality of roof members arranged close to each other in the direction intersecting the eaves-ridge direction.

  According to 3rd invention, a safety holder can be installed in a roof using the slit provided in the roof material.

  According to the fourth invention, when the safety means is held in the holding hole of the protruding piece after the safety holder is inserted into the overlapping portion of the roof material, the portion holding the safety means protrudes from the overlapping portion. Safety means can be easily held.

  Further, according to the fourth invention, since the protruding piece also serves as the holding means, the number of parts of the safety holder can be suppressed and the configuration can be simplified.

  According to the fifth invention, the safety means held in the holding hole can be protected from the peripheral edge of the holding hole, and the safety means can be prevented from being cut.

  According to the sixth invention, similarly to the first invention, the safety means can be easily and safely held on the roof.

  Further, according to the sixth invention, when the worker who wears the lifeline connected to the master rope stretched on the roof moves to the eaves side of the roof on one side, it is installed on the roof on the one side. One safety holder moves to the eaves side, and the other safety holder installed on the roof of the other side via the master rope tries to move to the building side. At this time, the protruding piece of the other safety holder comes into contact with the eaves side end of the roof material on the ridge side, and the further movement of the safety holder to the ridge side is restricted. Therefore, the movement of the one safety holding tool on the opposite side to the eaves side is also restricted, and the operator can be prevented from sliding down.
