The invention includes an access structure integration assembly and an integrated system using the assembly. An access structure integrated assembly includes at least one channeled structure and at least one joist socket slidingly engaged with the channeled structure. The channeled structure is configured to secure to a base structure, such as a suspended work platform system, and the joist socket is configured to secure to a second structure, such as a supported work platform system. An integrated system includes a base structure, a second structure and at least two integration assemblies, each assembly including a channeled structure secured to the base structure and a joist socket secured to the second structure and slidingly engaged with the channeled structure.

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).

A method utilizing an assembly of a sling detachably attached to an adjustment device for suspending one structure relative to another structure. The adjustment device comprises a pair of elongate spaced apart plates which are attached to each other and to a hook, for attachment to one of the structures, at the first end portion. Each plate has a plurality of pairs of longitudinally spaced aligned holes for receiving a pin for connecting one end of a sling to the adjustment device at a selected incremental one of the plurality of pairs of holes. The other end of the sling is connected to the other structure to adjust the distance over which the one structure is suspended relative to the other structure. To allow greater adjustability, two or more of the adjustment devices are joined end-to-end.

According to an example aspect of the present invention, there is provided a scaffolding arrangement to be attached to a deck structure, comprising a set of arms (2) including a carrier beam (5) for carrying the working levels and support structures needed in work, an attachment frame (1) for attaching the set of arms to the upper surface of the deck structure and platforms (103, 104, 105) for forming working levels.

A kit for erecting a platform. The kit comprises a plurality of quad-chord trusses. Each truss is attachable to others of the truss by eyelets on the ends of the chords. When the chords are spaced horizontally, the eyelet apertures are vertical for receiving pins, which allows a single pin to be inserted in eyelet apertures on one side of the truss so that one truss is swingable horizontally into position for rigid attachment end-to-end by inserting another pin in eyelet apertures on the other side of the truss. Each truss comprises a plurality of connector members for attachment to the trusses along their lengths. The kit further comprises a plurality of cross beams having connector members at their ends to mate with and attach to the truss connector members, and a plurality of tie-up mechanisms attachable to the trusses and to which a a supporting line from an overhead structure is attachable. The cross beams have overhangs at their ends for overhanging the upper ones of the chords to allow ease of movement along the chords and attachment. A track lies between the chords of each truss to allow movement of bolts along the track into position for insertion into decking apertures for attachment of the decking. The trusses may be foldable for transport and storage.

A chipping robot has a chipping gun attached to the end of a multi-axis robotic manipulator mounted on a powered, movable, platform that can be raised and lowered to access the underside of structures that may be substantial distances above the ground, for example, the underside of an elevated highway. The entire assembly is maneuverable under the work area and the platform may raised to access the concrete. Once the work area is in reach of the arm, the device is able to use numerous tools to complete essential steps of chipping portions of the concrete.

A connector comprises first and second parts having first and second plates respectively. The plates can abut to cover a panel opening and have slots in their abutting edges. The second part has a portion which extends in the second plate slot and which extends beyond the second plate edge a distance defining a neck. An arcuate portion extends from an end of the neck to receive the cable and has a threaded terminal end portion. In a first orientation of the second part, the neck extends vertically below the first plate to allow ease of manipulation of the second part to receive the cable between the arcuate portion and the panel. In a second orientation thereof, the neck extends horizontally within the first plate slot when the second part is in a closed position with the terminal end portion received in an aperture in the first plate.

A suspended scaffolding connector includes a central spine comprising an anchor connector at a top end thereof, a bottom lug at a bottom end thereof, and a top lug situated between the anchor connector and bottom lug. The connector further includes at least one top truss connector attached to the top lug and at least one bottom truss connector attached to the bottom lug, where the top and bottom truss connectors are configured and spaced for structural connection to top and bottom connectors of a scaffolding truss. The connector also includes top and bottom truss ledger connectors attached to the spine and situated between the top and bottom lugs and adapted for connection to a scaffolding ledger, and the anchor connector is adapted for connection to a suspension anchor and to support the scaffolding truss through the top and bottom truss connectors.

The invention includes a work platform and support system that includes a hub and joist configuration, wherein the hubs and joists are capable of articulation, or pivoting. One method of installation allows for sections of new work platform system to be extended from an existing suspended work platform system. The system is also capable of supporting, without failure, its own weight and at least four times the maximum intended load applied to it.

An expansion joint for building suitable to connect structural elements of a building structure to fill a space between the structural elements themselves is provided, in which the expansion joint is suitable for a connection with one of the structural elements in a longitudinal direction, and wherein the expansion joint has a plate body and a deformable body flanked or adjacent to the plate body along the longitudinal direction. The deformable body includes two superimposed and structurally independent portions connected to each other in a removable way, or configured for a removable connection with one another.
