Description

The present invention relates to a holding device for a safety device to which a safety belt or a lifeline is attached when working on a roof or the like.

On the roofs of private houses, buildings, station buildings, public facilities, etc., various operations such as maintenance and installation of pipes and solar panel equipment are performed. To prevent the operator from falling, after installing the holder on the roof, the worker attaches the safety belt worn, the hook and the cannabis provided at the free end of the lifeline to the holder.

The main rope tensioning equipment is complicated and time-consuming because it involves the work of installing the main rope pillars on both sides of the roof or at the four corners and then stretching the main rope between the pillars. Therefore, a holder that can be easily installed on the roof is desired. For example, there is known a holder that is inserted into a portion where the slate material overlaps with respect to a roof covered with the slate material (see Patent Document 1). Further, there is also known a safety belt attachment that can be fixed to a support on which a photovoltaic power generation module is mounted and hooked (see Patent Document 2).

JP-A-2017-110430 Patent No. 40565548

There are many types of roofs other than the slate type, and many roofs do not have facilities such as solar modules installed on the roof. In addition, the work place on the roof is not fixed to a specific place, but changes according to the work situation. Therefore, the place where the holder of the safety device is installed is limited by the type of roof and the equipment.

Therefore, regardless of the type of roof, equipment on the roof, etc., there is a need for a holder for safety equipment that can easily attach a safety belt or lifeline to a desired location on the roof.

The snow stopper of the present invention is a snow stopper that also has a function of holding a safety device, and has a bottom that is mounted on a roof and fixed. It is provided with a support portion for supporting a connecting member having a hole for hooking a hook provided at the end of a safety belt or a lifeline. Then, the connecting member is positioned so that the orientation of the hole can be adjusted. Here, the "snow stopper" includes a snow stopper having a portion (wings, etc.) for snow stopper, and a snow stopper having an angle for holding an elongated plate or a square timber extending along the ridge. Further, the "roof" may be any element that constitutes the roof, and includes members provided on the roof surface such as roof tiles, roof tiles, and roof tiles. The shape and structure of the snow stopper varies depending on the type of roof. For example, the snow stopper is applied to a snow stopper mounted on a tile bar (both with and without a heart tree) of a tiled roof. It is possible. The connecting member may be configured to be provided with an annular portion that forms a circular or elliptical hole so that the hook can be easily hooked.

In the present invention, a support portion capable of supporting a connecting member for hooking a hook through a hole is provided. By attaching the snow stopper to the roof, it can function as a holder for safety equipment. Further, the connecting member is positioned so that the orientation of the hole can be adjusted. Therefore, the operator can adjust the direction of the hole of the connecting member as desired and position the hole at a position where the hook can be easily hooked. For example, the connecting member may be positioned so that the orientation of the hole can be changed by 360 °. Angle type snow stoppers and the like are configured to support by sandwiching a plate material for snow stopper, and it is desirable that the upper surface of the support portion is flat. Therefore, the support portion may be provided with a through hole through which the end portion of the connecting member is passed so that the orientation of the hole can be adjusted below the through hole. For example, in the case where the connecting member is provided with a screw portion at the end such as an eyebolt, it is possible to position and fix the connecting member while adjusting the direction of the hole by fastening the nut.

When working on the roof, it is easy to lose balance when working while moving the roof surface diagonally, and it often moves in the direction along the ridge or in the direction perpendicular to it, that is, in the direction from the ridge to the eaves. Therefore, when the direction of the hole (the axis orthogonal to the hole) is along the ridge direction, it is difficult to see the hole and hook the safety belt when the operator approaches from the direction perpendicular to the ridge direction. The reverse is also true. Therefore, the operator may lose his balance before hooking. In another aspect of the present invention, the snow stopper is installed on the roof by using the snow stopper described above and so that the holes of the connecting member face in a direction other than the eaves direction and the direction perpendicular to the eaves. To do. Here, the installation includes installing the snow stopper to which the connecting member is attached in advance on the roof, and attaching the connecting member to the snow stopper arranged on the roof without attaching the connecting member. Is done. As a result, the hook can be easily hooked even when the worker approaches from either the ridge direction or the direction perpendicular to the ridge. For example, it is preferable to position the connecting member so that the hole of the connecting member is inclined by about 45 ° with respect to the eaves direction and the direction perpendicular to the eaves direction.

According to the present invention, it is possible to provide a snow stopper having a function of holding a safety device.

The bulging portion 12 of the top portion 10 is formed with a circular through hole 14 into which the threaded portion 4A of the eyebolt 4 is loosely fitted. Further, among the bulging portions 13A and 13B of the leg portions 11A and 11B, a square hole (through hole) 15 is formed on one side, and a through hole 16 is formed on the other side facing the square hole 15. The square root round head bolt 6 is penetrated through the square hole 15 and the through hole 16. The left and right corners of the top 10, that is, the front and rear corners of the upper edges of the legs 11A and 11B are notched, and the edges formed between the notches are bent inward to reinforce the rim 10a. It forms 10b, 11Aa, 11Ab, 11Ba, 11Bb. The lower side of the reinforcing edge portions 11Aa, 11Ab, 11Ba, and 11Bb of the leg portions 11A and 11B is cut out so as not to interfere with the bottom portion 5 when the snow stopper 2 is tightened. The lower end edges of the legs 11A and 11B are bent inward to form the claws 17A and 17B so that they can be bitten by the tile rod 8 when tightened. The claw portions 17A and 17B are formed by recessing the protruding edge portions facing each other in an arc shape. The open side of the legs 11A and 11B is wider than the width of the tile rod 8, and when the legs 11A and 11B of the support portion 3 are straddled by the tile rod 8, the claw portions 17A and 17B are bent inward. The edge is designed to face the side surface of the tile bar 8.

The bottom portion 5 has a wavy plate 20 formed in a longitudinal direction longer than the length in the front-rear direction of the support portion 3 and a width direction shorter than the length in the left-right direction of the top 10, and the wavy plate 20 from both sides. It is configured to have both side portions 21A and 21B rising upward. The corrugated plate 20 has a width that allows it to be placed in contact with the top cover 8A of the roof tile rod 8. At one end of each side portion 21A and 21B in the longitudinal direction, protrusions 22A and 22B curved from the upper edge of the side portions 21A and 21B and having a bent outer end are provided at the other ends of the side portions 21A and 21B, respectively. The vertical wall portions 23A and 23B are formed in each of the above. A drilling hole 24 and a stopper portion 25 protruding in the vicinity of the drilling hole 24 are formed in one of the standing wall portions 23B. An L-shaped metal fitting 26 is attached to the drilling hole 24. The L-shaped metal fitting 26 is held together with the L-shaped metal fittings of other snow stoppers arranged in the ridge direction by sandwiching and holding a long plate (not shown) for snow stopper installed along the ridge direction. Lower support portions 7A and 7B are formed at the centers of the side portions 21A and 21B, respectively. A groove 27 for avoiding interference with the reinforcing edge portions 11Aa, 11Ab, 11Ba, 11Bb is formed between the lower support portions 7A and 7B and the projecting portions 22A and 22B and the standing wall portions 23A and 23B. ..

In the bottom portion 5, the support portions 7A and 7B are arranged between the reinforcing edge portions 11Aa and 11Ab and the 11Ba and 11Bb of the support portion 3, and the one end screw portion 6C of the square root round head bolt 6 is arranged with one leg portion 11A. When it is inserted through the square hole 15 of the above and protrudes from the hole 16 through the insertion holes 28 and 28 of the support portions 7A and 7B, it is swingably supported by the support portion 3. That is, the bottom portion 20 is located above the claw portions 17A and 17B. The corner root round head bolt 6 is prevented from rotating when the corner root portion 6B continuously formed in the round head 6A is fitted into the square hole 15. A nut (fastener) 30 is screwed into the threaded portion 6C protruding from the other leg portion 11B via a washer 29. When the bottom portion 5 of the snow stopper 2 is placed on the roof tile rod 8 and the protrusions 22A and 22B are placed toward the upper edge side of the roof R, the claw portions 17A and 17B of the support portion 3 are on the side surface of the roof tile rod 8. It is designed to face. When the nut 30 is tightened, the legs 11A and 11B are plastically deformed inward, the inner edge of the claws 17A and 17B is bitten by the side surface of the tile bar 8, and the bottom 20 of the bottom 5 is the tile rod. The snow stopper 2 is pressed against the upper surface of the roof tile 8 so that it can be securely attached to the roof tile rod 8.

As described above, the snow stopper 2 is configured to mount the long plate on the flat rectangular top 10 of the support portion 3, but the eyebolt 4 is placed in the through hole 14 formed in the center of the top 10. The eyebolt 4 is attached to the top 10 by passing the screw portion 4A formed at the end of the annular portion 4B below the through hole 14 and screwing the nuts 31 and 32 on the back surface side opposite to the top 10. Can stick. The through hole 14 is a hole for mounting the eyebolt 4, is not used when functioning as the snow stopper 2, and is different from a bolt hole or the like required for the configuration of the snow stopper 2. The annular portion 4B on which the circular hole 4C is formed is configured so that the hook F (see FIG. 6) can be hung. Since the eyebolt 4 has a structure of being fixed by nuts 31 and 32, the position of the eyebolt 4, that is, the direction in which the circular hole 4C faces can be freely adjusted by 360 °, is positioned at a desired position, and is fixed to the snow stopper 2. can do. (A) to (E) of FIG. 5 each have a support portion 3, and (A) and (B) of FIG. 6 have eyebolts 4 attached to the support portion 3, respectively, and (A) to (F) of FIG. ) Indicates a contact member that is locked to the support portion 3.

Next, a method of using the snow stopper 2 according to the present embodiment will be described. The screw portion 4A of the eyebolt 4 is inserted into the through hole 14 from above the top portion 10 of the support portion 3, and the nuts 31 and 32 are screwed into the screw portion 4A from below and fixed to the top portion 10. At this time, the annular portion 4B is positioned so that the surface formed by the annular portion 4B is along the diagonal direction of the top portion 10. That is, the position of the eyebolt 4 is adjusted so that the direction in which the central axis PO (see FIG. 4) of the circular hole 4C faces is tilted by 45 ° with respect to the ridge direction CD and the direction SD orthogonal to the ridge. Next, the nuts 31 and 32 are tightened, the bottom portion 5 is arranged between the leg portions 11A and 11B of the support portion 3, and the screw portion 6C tip of the square root round head bolt 6 is inserted into the square hole 15 of one leg portion 11A. The washer 29 and the nut 30 are screwed into the tip of the screw portion 6C so as to project outward from the hole 16 of the other leg portion 11B through the insertion holes 28 and 28 of the support portions 7A and 7B of the bottom portion 5. .. As a result, the snow stopper 2 is assembled with the bottom portion 5 being swingably supported by the support portion 3. The assembled snow stopper 2 is attached to a tile bar 8 at the end near the lower edge RD of the roof R, for example, as shown in FIGS. 3 and 4. The attachment installed to function as a holder is performed by placing the bottom portion 5 on the upper surface of the tile rod 8 and the protrusions 22A and 22B toward the upper edge side of the roof R, and tightening the nut 30. When the nut 30 is strongly tightened, both leg portions 11A and 11B expanded to the open side are plastically deformed inward, and the claw portions 17A and 17B bite into the side surface of the tile rod 8 and are pressed against each other and are bitten by the tile rod 8. It can be securely attached. Further, the bottom portion 5 has both leg portions in a state where the support portions 7A and 7B are located between the reinforcing edges 11Aa and 11Ab of one leg 11A and between the reinforcing edges 11B and 11Bb of the other leg 11B, respectively. The wavy plate 20 is pressed inward from 11A and 11B to regulate the swing, and the corrugated plate 20 is pressed against the tile rod 8 and assembled integrally with the support portion 3.

When the worker approaches the snow stopper 2 from the ridge direction CD or the direction SD orthogonal to the ridge direction CD, since the inclination angle is set to 45 °, the circular hole 4C cannot be seen from one side. The inclination angle does not have to be exactly 45 °, but may be adjusted to about 45 ° (the direction of bisector). The cylindrical hole 4C may be visible from the ridge direction CD and the direction SD orthogonal to the ridge direction CD, and the eyebolt 4 may be positioned so that the circular hole 4C does not face in the direction along the ridge direction CD and the direction SD orthogonal to the ridge direction SD. .. When the snow stopper 2 is installed on the roof R, the eyebolt 4 may be removed, and when the work is performed, the eyebolt 4 may be attached to a predetermined snow stopper. In this case, the support portion 3 is taken out and an eyebolt is attached. Further, a snow stopper with an eyebolt, which is not used as a snow stopper but is used exclusively as a holder, may be installed on the roof together with other snow stoppers not equipped with the eyebolt.

By configuring the snow stopper 2 having the function of holding the safety device in this way, the snow stopper 2 attached to the tile bar 8 fulfills the snow stopper function during snowfall, while the configuration in which the eyebolt 4 is attached makes it safe. Functions as a holder for equipment. Since the snow stopper 2 is firmly fixed to the tile rod 8 so that it can withstand a large pressure due to snow during snowfall, it can sufficiently withstand the load even when a person loses balance. .. Further, since the direction of the circular hole 4C is inclined by 45 ° with respect to the ridge direction CD and its orthogonal direction SD, when the worker moves along the ridge direction CD or its orthogonal direction SD, the annular portion The void of 4B is easy to see. Therefore, the hook attachment work is easy and the safety is improved. On the other hand, by adopting a structure that follows the conventional snow stopper 2 except that the through hole 14 is provided at the top 10 of the support portion 3, the safety device can be held without complicated structure or excessive attachment of additional parts. Provides a mechanism. Further, since the position of the phase bolt is adjusted below the top 10 of the support portion 3, the function of attaching the safety device can be fulfilled without impairing the snow stop function.

In the present embodiment, the connecting member is composed of an eyebolt 4 having an annular portion 4B, but the present invention is not limited to this, and if the member has an annular portion with a gap formed inside, the annular portion is rectangular. It goes without saying that the shape may be oval, or may have a partial opening (the hole is not closed). Further, the eyebolt 4 which functions as a safety rope holding member is directly attached to the top 10 of the snow stopper 2, but the present invention is not limited to this, and a member for increasing the height is interposed between the eyebolt 4 and the top 10. A member may be provided. Further, the snow stopper 2 may be attached to a support member (not shown) provided on the roof R and connected to the tile bar 8. Further, a member having a portion for hanging a hook other than the eyebolt may be attached to the support portion by adjusting the direction of the hole in the snow stopper. In the present embodiment, it is configured as an angle type snow stopper to be attached to a tile bar, but it is prepared according to a feather type snow stopper equipped with a snow stopper plate portion or another roof type. It can also be applied to snow stoppers. In this case, for example, a through hole can be provided in a flat member facing upward on the roof.
