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.

The present invention relates to a working system, including at least one fastened rope node, at least one mobile rope node, and at least one suspended rope node. The three nodes are connected by using a rope, the fastened rope node is fastened to a surface of a building, the suspended rope node includes at least one working apparatus, and the working apparatus works on a side facade of the building. The mobile rope node can move on the building and change a suspension position of the suspended rope node. In the present invention, safety of a facade working robot is improved, and a working scope is expanded.

A lightweight composite roofing support system is disclosed. The roofing support system includes a longitudinally-extending core member having a wedge-shaped lateral cross-section, a first side, and a second side, the first side and the second side tapering toward one another at a first predetermined acute angle (), the core member comprising a core material. The roofing support system also includes a cover layer comprising a cover material, the cover layer disposed on and covering at least one of the first side and the second side, the cover material being substantially more compressible than the core material, the core member and cover layer comprising a first roofing support.

A scaffolding to be fastened to a bridge or the like deck structure comprises a boom system (2) for supporting the working platforms and the support structures needed for the work and for fastening the boom system of the fastening body (1) to the upper surface of the deck structure. The boom system (2) is connected to the fastening body via a swivel quadrangle (3, 6, 11, 12).

The present disclosure relates to a height accessible working platform. The disclosed working platform generally comprises a frame attachable to a lifting system for being moveable along the vertical axis and suspended thereto; a cradle; a first arm structure having a proximal end terminated to the frame and an distal end attached to the cradle, the first arm structure being extendable and retractable to displace the cradle respectively away from and closer towards one of lateral sides of the frame along a first axis substantially perpendicular to the vertical axis; and a counterweight mechanism mounting at one lateral side of the frame opposing to the cradle, the counterweight mechanism being configured to balance the working platform corresponding to displacement of the cradle along the first axis.

A method for installing and deploying concealed mounting points for a davit or jib crane on a roof patio or large balcony covered with stone pavers. Specifically, a metal plate assembly lower flange is affixed to the concrete roof slab with its contact points covered by waterproofing membrane. The metal assembly hard point upper flange holes correspond to the holes in the mounting base of the davit or jib crane. The metal assembly when installed is lower than the pavers supported by metal pedestal transition components. As such, the metal assembly hard point is concealed and covered by a removable cover plate that also sits on top of the metal pedestal transition components and is flush with the top of the pavers.

A facade gantry allows for close inspection of a facade using remotely operated cameras, probes, and/or sampling devices. These devices are located in a housing that is positioned in front of a facade by a system of cables, from which it is suspended, that allow for movement in any direction in a plane. Two cables are attached to the housing containing the sensors and tools and are wound onto two separate spools located on the roof at the vertical boundaries of the inspection area. By winding and unwinding these spools, the housing can be raised, lowered, and moved from side to side. The invention further has an optional shed located on the ground that protects pedestrians in the case of a suspension system failure. The shed moves to maintain a position directly under the housing. The gantry optionally allows for repair of the facade by using remotely operated repair tools.

A method of constructing a structure in which an item is to be installed at an elevated height on the structure. Hoists are hung from the structure. A platform is moved from ground level and positioned at a first elevated position between ground level and the hoists. The platform is attached to the hoists at the first elevated position. After the platform has been attached to the hoists, the item is moved onto the platform. The item is lifted on the platform to a second elevated position for installation at the elevated height on the structure and the item is installed at the elevated height.
