INDIVIDUAL SCAFFOLDING POST

An individual scaffolding post made of metal for facade scaffolding or of facade scaffolding has secured thereon a single rosette for detachably securing at least one horizontal bar. A railing securing device is secured above the rosette, on which a railing strut is detachably supported. The railing securing device includes a rigid bracket permanently secured to the post, which together with an outer surface of the post surrounds and engages around a vertical receiving slit through-opening. A railing rod end of the railing strut has a first recess on the underside, which is open to side surfaces of the railing rod end extending away from one another and is open downwards. The railing rod end has a mounting hook limiting a first recess and partially surrounding same with its free hook end extending to the rear. The free hook end engages behind the bracket contact part of the bracket.

Lockable scaffold toeboard system using sleeves
10995503 · 2021-05-04 ·

A scaffold toeboard system for locking a toeboard between two vertical scaffold members where each vertical scaffold member includes a tubular member having a diameter and an outer shape. The toeboard system includes a toeboard having an elongated member with a fixed terminating end and an adjustable terminating end. The toeboard further includes a front portion, a top edge, a bottom edge, and a rear portion. The toeboard system further includes a second sleeve fixed to the fixed end of the toeboard, and a first sleeve fixed to the adjustable end of the toeboard. Slidably positioned in the first sleeve is a slide lock sleeve. The toeboard system includes a locking mechanism positioned at the adjustable terminating end, to fix the position of the slide lock sleeve to the first sleeve. The slide lock sleeve includes two fingers or tabs extending outwardly from the front edge of the slide lock sleeve. The two fingers are separated by a horizontal distance of about the diameter of a scaffold vertical member.

Catwalk floorbeam connection system

A catwalk system having a pair of side trusses formed of a top chord and bottom chord connected by a plurality of vertical posts and diagonal posts. The bottom chords have a plurality of joints formed of a bottom plate, opposing side plates and wing plates that form a pocket. These pockets receive an end of floorbeams which are bolted to the side plates. The bottom plate also includes a wind brace section that receives an end of a diagonal wind brace therein. The fabricated side trusses are shipped to the job site where the catwalk is quickly and easily assembled by aligning a pair of side trusses in parallel space alignment and installing floorbeams in the pockets of opposing joints. To provide additional rigidity diagonal wind braces are installed in a zig-zag formation between diagonally opposite joints. This arrangement provides a quickly assembled catwalk that requires minimal assembly.

Structure for staging materials on a roof structure

The apparatus may include a ridge member, a first arm rotatably coupled to the ridge member and extending outward, relative to the ridge member, in a first plane angled relative to a first pitch of a roof structure. Also, the apparatus may include a second arm rotatably coupled to the ridge member and extending outward, relative to the ridge member, in a second plane angled relative to a second pitch of the roof structure. The ridge member may be positioned at an apex between the first pitch and the second pitch along a ridge of the roof structure. Further, materials for installation may be placed on at least one of the first arm and the second arm positioned between the roof structure and the materials. Additionally, the apparatus may include a load arm coupled at each respective end portion of the first arm and the second arm.
