And an inverted L-shaped support arm to which a lifeline suspended downward is attached.

[0003]

[Problems to be Solved by the Invention] In the case of a conventional hanging bracket for a building, when the height of a parapet on the roof is several meters, an operator uses a ladder or a stepladder to move onto a lifeline from a support arm. There is a drawback that the transfer to the lifeline from the support arm is dangerous, and that the movement of the support arm, the ladder, and the stepladder is troublesome, and that efficient cleaning of window glass or the like cannot be performed.

The present invention has been made in view of the above-mentioned conventional drawbacks,
To provide a hanging bracket for a building that can easily climb even if the height of the parapet is several meters and can safely move on to the lifeline from the support arm, and can be easily moved to the next side, and can be easily performed. It is an object.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the scope of the present invention.

[0006]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a parapet at the top of a building, the upper part of which is fixed to the parapet at a predetermined interval so as to protrude inward from the inner side of the upper part. A plurality of locking pieces having locking grooves formed therein, a plurality of fixing brackets having through holes fixed to a parapet at a lower position of these locking pieces, and A ladder that can climb from the rooftop of the building to the upper part of the parapet that can be locked in the locking groove of any one of the locking pieces, and the penetration of the fixing bracket attached to a portion near the lower part of the ladder A mounting piece having an insertion hole into which the locking fitting inserted into the hole is inserted, and a ladder-like part that protrudes upward when not in use at a position near the top of the ladder and protrudes outward from the upper part of the parapet when in use. Can support the lifeline Constitute the building for the hanging bracket in the that the support arm.

[0007]

With the above-structured hanging bracket for a building, the upper portion of the ladder is locked in the locking groove of the plurality of locking pieces, and the insertion hole of the mounting piece at the lower portion of the ladder is formed with the plurality of holes. The ladder is fixed to the parapet by inserting the locking metal into the through hole of the fixing metal. By rotating the support arm, the tip end protrudes out of the building.
