A bridge overhang bracket assembly includes a top member, a diagonal member and a side member. The top and diagonal members are pivotally attached proximate to respective outer and upper ends thereof. The top and side members are pivotally attached proximate to respective inner and top ends thereof. The diagonal and side members are pivotally attached proximate to respective lower and bottom ends thereof. The side member is configured so that its length between the bottom and top ends is adjustable.

A temporary shield erected between two flanged structural members of a bridge or other structure, a kit therefor, and a method for erection of the shield. A plurality of length-adjustable beams have end portions which are rested on flanges respectively of the structural members. Decking is attached to the beams. At least one elongate member is cantileverly extended from at least one of the beams to underlie a structural member flange to prevent wind lift up of the shield.

An improved bridge overhang bracket assembly may include top, diagonal and side members. A hanger element may be mounted to the top member and pivotally attached proximate to the top end of the side member. The hanger element may be translatable along the top member for adjusting its longitudinal position, to vary the positions of the diagonal and side members quickly and easily, without disassembly, and may enable folding of the members to a shipping/storage position. A second hanger element may be mounted to the top member for attaching the assembly to a tie rod. The diagonal member may include at least one connection tab for receiving a bolt to connect the top and diagonal members together in the shipping/storage position. Also disclosed is a fastener assembly for securing a side rail to a T-bolt channel.

A duct support device is provided. The device includes a clamp assembly having a channel dimensioned to removably secure to a support structure, wherein a width of the channel is selectively adjustable via actuation of a pair of clamp handles affixed to the clamp assembly. A first arm member is affixed to the clamp assembly at a proximal end of the first arm member. A second arm member is pivotally affixed to a distal end of the first arm member. A third arm member is perpendicularly affixed to a distal end of the second arm member. A brace is affixed to the third arm member parallel to a longitudinal axis of the third arm member, wherein the brace extends along a length of an upper side of the third arm member. In some embodiments, a fourth arm member is perpendicularly affixed to a distal end of the third arm member.
