Description

  The present invention relates to a suspension device that is clamped and fixed to a parapet formed in a building and suspends an operator to inspect and repair the exterior surface of the building.

  Conventionally, as shown in FIG. 13, a front support member 101 is hung down at a right angle on the front lower side of the support arm 100 as a method of hanging a luggage or the like by being clamped and fixed to a parapet formed in a building. In addition, a rear support member 102 is fitted and arranged on the rear end side of the support arm 100 so as to be slidable. Then, the front support member 101 and the rear support member 102 sandwich the front and back of the parapet 103 formed in the building, and the support arm 101 is horizontally positioned on the upper surface of the parapet 103 so that the wire 104 is attached to the support arm 100. There is a hanging tool 105 that hangs and supports a load or the like with the wire 104 (for example, Patent Document 1).

JP 2002-81206 A

  However, in the conventional hanging tool 105 as described above, the area where the front support member 101 and the rear support member 102 are in contact with the parapet 103 is small when sandwiched and fixed to the parapet 103 formed in the building. For this reason, there is a possibility that the hanging tool 105 may come off during the operation due to the weight of the load to be suspended and the impact generated when the load is lifted. Further, since the pressure acting on the parapet 103 becomes large, for example, in a parapet formed in a low-rise prefabricated house or the like, in which the muscle material is substantially vertically embedded at a predetermined interval, the inner wall surface of the parapet is damaged. May occur. Furthermore, when the outer wall surface which comprises a parapet is an inclined surface, it is difficult to attach the conventional hanging tool to this parapet. Even if the angle of the front support member 101 is changed so as to correspond to the slope of the slope surface and the hanging tool 105 is attached, the above-described problems occur and the work is being lifted while the worker is being lifted. There is a possibility that the person or the wire 104 contacts the eaves formed below the slope of the slope and the eaves are damaged.

  The present invention has been made for the purpose of solving the various problems as described above, and securely attaches the parapet to the parapet whose outer surface is a sloped surface without damaging it. Further, the present invention relates to a hanging device that does not have a risk of damaging the eaves edge during the hanging work.

  In order to achieve the above object, the suspension device according to claim 1 is detachably clamped and fixed to a parapet in which a plurality of substantially vertical bars provided at the roof edge of a building are present at predetermined intervals. A clamping and fixing portion provided in a main body frame portion constructed by framing a plurality of frame pieces, a guide member for guiding a rope for suspending an operator, and a rope winding for winding up the rope In the suspension device comprising the upper machine, the clamping and fixing part is provided on the main body frame part so that the clamping and fixing part is placed on the upper surface of the parapet, and the parapet constitutes the parapet. A rotation fixing portion provided on the main body frame portion so as to be in contact with an outer gradient surface of the building and to be rotatable in accordance with the gradient of the gradient surface; and via the rotation fixing portion and the parapet. Facing each other, and the opening of the inner wall of the parapet is detachable from the inner wall. The mounting member provided on the main body frame portion so as to face the side, and the mounting member so as to be longer than the interval between the plurality of muscle members in contact with the inner wall surface of the parapet and in the parapet. And a fixing rod that is detachably fitted and held.

  The suspension device according to claim 2 is the suspension device according to claim 1, wherein the inclined portion is connected to the rotation fixing portion and the flexible body and is placed in contact with the gradient surface, and below the gradient surface of the gradient surface.

It can be supported by other streaks. In addition, since the fixing rod is formed in a long shape, the pressure can be dispersed, so that the inner wall surface of the parapet is not damaged. When the operator is suspended by the suspension device, a vertically upward force acts on the fixing rod. However, since the fixing rod is detachably fitted and held on the mounting member, the fixing rod is substantially integrated with the mounting member. Therefore, even if a vertically upward force acts on the fixing rod as described above, the fixing rod Without being detached from the attachment member, the suspension device can be securely clamped and fixed to the parapet.

  According to a second aspect of the present invention, in addition to the effect of the first aspect, the eaves tip protector includes an inclined portion that is connected by the rotation fixing portion and the flexible body and is placed in contact with the slope surface. The pressure acting on the gradient surface when the operator is suspended can be dispersed, and the gradient surface is not damaged. In addition, the eaves tip protector comprises a substantially U-shaped eaves tip protector formed below the slope of the inclined portion so as to have a predetermined distance from the eaves tip formed below the slope of the slope surface, Since the eaves edge protection part covers the eaves edge, workers, ropes, etc. do not come into contact with the eave edge, and damage to the eaves edge can be prevented.
