DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supports a rope attached to a working gondola which is used for cleaning window glass or the like of a building and adjusts the length of two ropes and moves left and right. The present invention relates to a hanging bracket for a building.

[0002]

2. Description of the Related Art Conventionally, a hanging fixture for a building that supports a working gondola that moves left and right by adjusting the length of two ropes is attached to the parapet so as to protrude inside the parapet at the rooftop of the building. A pair of fixing brackets fixed and separated by a predetermined distance, and a pair of inverted L supporting a rope whose lower end is detachably attached to the pair of fixing brackets and whose tip end protrudes outward from the upper part of the parapet. And a support arm shaped like a letter.

[0003]

[0006] A conventional building hanging bracket is provided with a pair of support arms for extending and retracting two ropes to move a work gondola on which an operator rides in the vertical and horizontal directions. Has a drawback that a relatively large load is applied to the inside and it is easily deformed. In order to solve this drawback, there is also a plan to fix or dwell a reinforcing material on a pair of support arms by welding, but if such a reinforcing material is fixed,
When the support arm is moved, there is a drawback that it is heavy and the workability is deteriorated.

The present invention has been made in view of the above-mentioned conventional drawbacks,
It is an object of the present invention to provide a hanging metal fitting for a building which has a simple structure, is easily attached and detached, and has sufficient strength even if the operator swings right and left.

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 In order to achieve the above object, according to the present invention, a parapet on a rooftop of a building is fixed at a predetermined interval so as to protrude inward from an inner wall surface of the parapet. A pair of fixing brackets, and a pair of inverted Ls whose lower ends are detachably attached to the pair of fixing brackets and whose tip ends project outward from the upper part of the parapet.
And a rope support portion for supporting a rope for suspending a work gondola formed at the distal ends of the pair of support arms, and a portion near the distal ends of the pair of support arms, respectively. A formed locking piece,
A locking portion is formed at a front end portion for engaging with a locking piece of the pair of support arms to lock immovably in up, down, left, and right directions. The building suspension fitting is constituted by a reinforcing frame having an attachment portion that can be attached as much as possible.

[0007]

With the above-structured hanging bracket for a building, a pair of inverted L-shaped support arms can be detachably attached to a fixing bracket fixed to a parapet, respectively. By engaging the engaging portion with the engaging piece of the supporting arm and attaching the reinforcing frame, the strength in the left-right direction of the pair of inverted L-shaped supporting arms is reinforced.
