Description

This invention is a slope of a facility such as a highway having a sound insulation wall by holding a sound insulation plate on a support made of H-shaped steel, such as a facility in which horizontal support H-type support posts are installed with a plurality of intervals. The present invention relates to a horizontal master rope mechanism for connecting a safety belt for an operator, which prevents the operator from slipping and falling in various operations performed on the surface.

  Conventionally, as shown in FIG. 8, on the slope D of a facility such as a highway equipped with a sound insulation wall by holding a sound insulation plate on an H-shaped steel column, various works such as earth retaining are carried out for the purpose of preventing slope collapse and landslide. Work such as weeding is carried out. Since these constructions are performed on the slope and there is a risk of the operator E sliding down or falling, one end of the rope attached to the worker E's safety belt is attached to the main rope suspended from above. (In FIG. 8, the main rope and safety belt are omitted).

For example, in the one described in Patent Document 1, an anchor is driven into the uppermost part of the slope, a main rope is attached to the anchor, and the anchor is hung downward, and an operator attaches a belt, an auxiliary belt, and a temporary fitting to the main rope. Work is carried out by attaching its own safety belt via
JP 2002-186679 A

However, in the one described in Patent Document 1, the main rope attached to the anchor is hung from above, and the main rope cannot be attached unless the anchor or the like is hit. The main rope could not be attached to the pillars and wall materials of H-shaped steel. In addition, the main rope suspended from above can move relatively smoothly in the vertical direction, but is limited to the movement in the horizontal direction. In order to perform the work sufficiently, further movement in the left-right direction is inevitably required. Therefore, when moving in the left-right direction, the worker had to catch the adjacent main rope and replace it with a temporary fitting.
In addition, in slope work, securing the location where the end of the rope attached to the safety belt is attached is an important issue in order to prevent a fall accident caused by wearing the safety belt.

This device was devised in view of such a situation, and in the slope work, securing the attachment part of the end of the rope to be attached to the safety belt of the worker is provided on the column having an H-shaped horizontal section.

First, a slope of a facility provided with a wall surface with a horizontal cross-section H-type column and plate material used in this embodiment will be described. As shown in FIG. 1, a plurality of columns A made of H-shaped steel are continuously provided at regular intervals, and sound insulation plates B are fitted in the recesses on both sides of these columns A, respectively. A sound insulation wall C is provided. Here, it is assumed that it is in an expressway facility, and the pillar A is erected every 4000 mm to form a sound insulation wall C, and a slope D is formed below the sound insulation wall C.

Next, how to provide the horizontal master rope mechanism for connecting the safety belt will be described. As shown in FIG. 1, after attaching this support | pillar attachment bracket 1 to the support | pillar A, the adjacent support | pillar A is skipped and another support | pillar attachment bracket 1 is attached to the position of the same height of the following support | pillar A. As shown in FIG. As shown in FIG. 6, a master rope provided with a master rope attachment portion 6 provided at both ends of each of the column attachment brackets 1 and provided with annular locking portions (hooks) 9 a that can be partially opened and closed at both ends. 9 is attached and stretched, and a first rope 10 having an annular locking portion (hook) 10a that is partially openable and closable at one end is movably attached to the master rope 9 and hangs downward.

On the first rope 10, a lock device 11 a that can be moved and fixed is provided at one end, and a second rope 11 that is provided with an annular locking portion (hook) that is partially openable and closable is attached to the other end. Then, a locking portion (hook) at the other end of the second rope 11 is attached to the safety belt 12 of the worker E.

  Then, the support | pillar mounting bracket 1 used in this Example is demonstrated. As shown in FIGS. 2, 3 and 4, this column mounting bracket 1 has two angle members 3 having a constant width and having a blade portion 2 with one end tapered, in an angle shape in plan view. The blade portions 2 are provided opposite to each other, and two through holes 4 are provided at the upper and lower ends of the other end portions of the angle members 3, and left and right at intermediate positions between the two upper and lower through holes 4. Two small holes 5 are arranged in parallel.

Further, each end 6a of the master rope attaching part 6 is inserted into the two small holes 5 and welded thereto with the substantially U-shaped master rope attaching part 6 lying sideways. And when attaching this support | pillar mounting bracket 1 to the support | pillar A to the said through-hole 4, the volt | bolt 7 is each inserted from the side, The leg part of the said volt | bolt 7 which protruded in the direction opposite to the direction which inserted the volt | bolt 7 is inserted. A nut 8 is screwed onto 7a, and the column mounting bracket 1 is mounted and fixed to the column A.

At the site where the slope work is performed, the post mounting bracket 1 disassembled into the angle member 3, the bolt 7 and the nut 8 is prepared. As shown in FIG. 5, two angles of the column mounting bracket 1 are formed in the gaps between the inner end surfaces that form the concave portions on both sides of the column A and the outer surfaces of the end portions of the sound insulating plate B from the outside of the column A. The blades 2 of the material 3 are inserted and provided opposite to each other.

Thereafter, as shown in FIG. 3, bolts 7 are respectively inserted from the side into the two upper and lower through-holes 4 facing each other, and the two angle members 3 are inserted and protruded from the other side. Nuts 8 are screwed to the respective leg portions 7a of the bolts 7, and the column mounting bracket 1 is mounted to the column A. At this time, if the direction in which the upper bolt 7 is inserted and the direction in which the lower bolt 7 is inserted are reversed, a good balance is obtained when the column mounting bracket 1 is mounted on the column A.

As described above, the ends of the master rope and the main rope (the first rope in the first embodiment) could not be attached to the existing facility equipment. This strut mounting bracket can be easily and reliably mounted on the strut, and the master rope and the main rope can be mounted on this strut mounting bracket. And, in the range where the horizontal strap mechanism for connecting the safety belt is attached (between the two attached bracket mounting brackets), the operator E can move safely and easily in the vertical and horizontal directions. It can be done sufficiently and its efficiency is improved. When the work at the place is completed, the work is moved to the place where the next work is performed, and the work is performed with the horizontal master rope mechanism for connecting the safety belt. At this time, the mounting / removal of the column mounting bracket 1 to / from the column A can be done by loose tightening of the bolt 7 and the nut 8 and can be very easily performed, and it is easy to use as a horizontal master rope mechanism for connecting a safety belt.

In the embodiment, the master rope 9, the first rope 10, the lock device 11a, and the second rope 11, the master rope, the first rope, the lock device, and the second rope are not limited to these, In an Example, what has the structure as said member and can show | play an effect without trouble should just be. For example, instead of the master rope 9, as shown in FIG. 7, a galvanized steel strand 13 or the like may be used, and at that time, a winding grip 15 is provided at both ends of the galvanized steel strand 13, One end of the winding grip 15 may be locked to the support bracket 1, and the other end of the winding grip 15 may be locked to the support bracket 1 via the turnbuckle 14.

Moreover, although the highway facility is used as an object to which this horizontal belt for the safety belt connection is attached, the horizontal cross section to which this horizontal belt for the safety belt connection can be attached has a plurality of H-type struts. Of course, other facilities may be used as long as the facilities are open. Further, although H-shaped steel is used as the column A having an H-shaped horizontal cross section, other horizontal cross-section H-shaped ones may be used as long as the plate material can be attached and held. Moreover, although the sound insulation board B is used as a board | plate material attached and supported to this support | pillar A, not only a sound insulation board but of course other board | plate materials may be sufficient.

Furthermore, although all of one end edge of the column mounting bracket 1 is the tapered blade portion 2, it is not always necessary to use a blade portion, and a flat end edge may of course be used. In addition, when attaching the column mounting bracket 1 to the column A, the two bolts 7 are inserted through the opposite directions. However, as shown in FIG. good.

Moreover, although the thing which provided the two through-holes 4 and the small hole 5 in the other edge part of the angle material 3 was used as the support | pillar mounting bracket 1, as a structure of the support | pillar mounting bracket 1, it does not restrict to this, The support bracket 1 can be attached to the support A by using one bolt and nut to attach the master rope attachment part to the other through hole, and the master rope attachment part 6 is substantially U-shaped. However, the master rope attaching portion is not limited to a substantially U shape, and other configurations may be used as long as the end of the master rope 9 can be reliably attached.

In addition, the column mounting bracket 1 is mounted, and then the adjacent column A is skipped and another column mounting bracket 1 is mounted on the next column A. This is a horizontal parent in the temporary scaffold in the occupational safety and health regulations. This is because the use range of one of the ropes is within 1000 mm, and here, since the span of the pillar of the sound insulation wall is every 4000 mm, the span is 8000 mm. Therefore, it is of course possible to attach the column mounting bracket 1 to the adjacent column A.
