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 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 panel is disclosed which is suitable for installation to form a platform or part of a platform in a void of a building structure. The panel is operable to extend between a first support member and a second support member both of which extend across at least a portion of the void. The panel has: a deck component with: a first end and a second end opposite the first end; a pair of opposed, substantially straight sides each extending from the first end to the second end; and a substantially planar surface portion which extends: between the opposed sides at the first end, and from the first end at least part of the way, but not necessarily all the way, to the second end; and one or more first engaging formations at the first end of the deck component and operable to engage with the first support member to support the deck component relative to the first support member, and one or more second engaging formations at the second end of the deck component and operable to engage with the second support member to support the deck component relative to the second support member. At least one out of the first and second engaging formation(s) is/are configured to support the relevant end of the deck component relative to the relevant support member from approximately directly vertically beneath, and/or from approximately within vertical planes containing, each of the straight sides of the deck component.

A walkway system includes brackets that are connectable to vertical frame members and supportable by horizontal frame members. Walkway support members include lips that engage with the brackets, horizontally-oriented portions that support a walkway member, and vertically-oriented portions that contact the building to stabilize the walkway member.

An adjustable suspension assembly for suspending a lower structure such as a platform from an upper structure such as a portion of a bridge. A sling, which is attachable at one end to the upper structure, is attached at its other end to one end of a chain. A device, which is attachable to the lower structure, has a pair of aligned apertures in its side walls for receiving pins. The pins are spaced to receive a thickness of a chain link but not to receive a width of the link, whereby a selected link to achieve a desired lower structure height may be cinched between the pins. The other end of the sling, which comprises a cable, has an eyelet formed by folding an end portion of the cable back over the cable and swaging the cable end portion to the cable. The chain is attached to said eyelet by receiving the end portion of the cable in one of the chain links before the cable end portion is swaged to the cable.

A wall mount bracket for HVAC Equipment such as a heat pump, AC condensing unit, and preferably the exterior condenser unit of a mini split system. The system can advantageously be used in colder climates to prevent equipment from freezing and keep equipment above the level of the snow, etc. The wall mounts herein employ an offset to space the unit away from the wall of the structure to provide clearance on the rear of the unit. The offset also allows the units to be mounted above the top of the foundation wall without disrupting the exterior siding of the structure.

The invention relates to a supporting framework having at least one suspension device for a diagonal cross brace that reinforces the supporting framework, wherein the suspension device has receiving fingers for openings provided on the ends of the diagonal cross brace, characterized in that two first receiving fingers of the suspension device each have a bent end portion, and second receiving fingers situated opposite from the first receiving fingers have a pivotable end portion.

An upright support bar includes a mount disposed at the pivotal joint between an outer tube and an inner tube, a button pivoted to the mount and providing an actuation end, a finger grip and a latching portion so arranged that when the actuation end is biased downward, the latching portion is engaged in one of a series of holes of the inner tube, and a sliding block with a locking piece mounted on the mount movable relative to the mount between a first position where the locking piece is abutted against the finger grip to lock the button and a second position where the locking piece is released from the finger grip to unlock the button.

The scaffold securing clip and strap comprises a ratchet strap, a scaffolding jib and a bracket. The scaffold securing clip and strap is configured for use with a stanchion. The ratchet strap attaches the scaffolding jib to the stanchion. The bracket attaches the scaffolding jib to the stanchion. A first instantiation of the scaffold securing clip and strap works in conjunction with a second instantiation of the scaffold securing clip and strap to support one or more planks. Specifically, the scaffolding jib of the first instantiation and the scaffolding jib of the second instantiation combine to raise one or more planks to an elevation above a supporting surface of the stanchions to which the first instantiation and the second instantiation are attached. The elevated one or more planks form a raised horizontal surface capable of supporting a load.

A system for releasably securing a platform in a raised position is disclosed. A track is provided. An arm is connected at a first end to the platform. A second end, with a lug, is biased toward a side portion of the track. The lug is configured to ride in the track. As the platform is raised, the lug rides upward and enters the top portion and clears a first vertical wall, whereupon the lug rests in the depression and thus supports the platform in the raised position. As the platform is raised further, the lug clears a second vertical wall, whereupon the lug can ride downward in the side portion and through a bottom portion, past a door and out an open end of the bottom portion.

An adjustable support for use in shuttering formwork comprising a base member, a shuttering contact member, and a bracing member, wherein the base member, the shuttering contact member and the bracing member are engaged hingedly with one another. The bracing member is engaged securably with the shuttering contact member and the base member. The bracing member is adjustable, such that adjustment of the bracing member causes rotation of the shuttering contact member about the base member. Also disclosed is a method for supporting shuttering comprising providing one or more adjustable supports as described above, affixing the or each base member to a substantially static object, assembling the or each bracing member and the or each shuttering contact member as described above, adjusting the or each bracing member and attaching the or each shuttering to the or each shuttering contact member.
