In the conventional building suspension bracket, the rear end of the inverted L-shaped support arm is attached to the fixing bracket by a pivot pin, a bolt, or a nut. The work of supporting the support arm and mounting the pivot pins, bolts and nuts is troublesome, and it is troublesome and dangerous.

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 that can be easily and safely attached to and detached from a fixing metal, can be mounted at an arbitrary position, and can be used safely.

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, the present invention provides a free end portion having a H-shaped cross section or a T-shaped cross section fixed to a parapet on the roof of a building along the inner surface of the parapet. And a pair of locking brackets formed with hooks that are locked to the lower end of the support plate at the lower end that abuts the outer surface of the support plate of the fixing bracket at a predetermined interval. A pair of mounting brackets each having a pressing piece that presses against an inner surface near the top of the support plate that is rotatably mounted with a pivot pin at a position near the top of the pair of locking fittings; A support arm whose distal end attached to the mounting bracket protrudes outward from the upper part of the parapet, and a mounting part such as a lifeline are formed at a portion near the distal end protruding upward and attached to the pair of mounting brackets. Posts and building suspension Constitute the bracket.

[0007]

The above-structured hanging bracket for a building is supported on a support plate of a fixing bracket at a portion where a pair of mounting brackets is to be mounted by holding a column or a support arm. By rotating the support arm from this state so as to protrude out of the building, the hooks of the pair of locking fittings are locked with the lower end of the support plate, and the pressing pressure pieces of the pair of mounting fittings are pressed. The outer surface near the upper portion of the support plate is pressed, and the support plate of the fixing bracket is attached to the support plate by the pair of locking fittings and the pressing pieces of the pair of mounting fittings. The lifeline or the like is attached to the attachment portion of the lifeline or the like of the support plate, and is used by being suspended below a portion near the tip of the support arm.
