A safe scaffold includes door type frames, crossbars, and toe boards. The door type frame has a ledger, located in the lower end, connected to standards that are parallel to each other and are installed with combined pins thereon individually. The crossbar includes joint bar members having engaging holes engaged with the combined pins of the door type frame, and connects one door type frame to another door type frame in a cross link method, or connected to other joint bar members through the engaging couplers. The toe board is provided on the ledgers of every two adjacent door type frames. The invention creates an available space for setting guardrails by lowering the position of the toe board of the scaffold, adjusts the position and combination of the crossbars to form guardrails, and reduces the gaps of side rails.

A scaffold truss member and a scaffold truss connector. The scaffold truss member includes lower and upper horizontal members, joined by bracing members. The upper horizontal member terminates at each end with a coupling, while the lower horizontal member terminates without a coupling on either end. The scaffold truss connector includes a lower truss connector that has a channel, open on two ends to accommodate the lower horizontal member of a scaffold truss, and an upper truss connector, which is either integral or joined to the lower truss connector.

Embodiments described herein include an expansion assembly for a scaffold having a first support member, the first support member having a connector bar, the first support member including a hook flange, the hook flange projecting laterally from the connector bar, a hook, the hook extending from the hook flange, where the hook is spaced apart from the connector bar, a support bracket, the support bracket extending from a support bracket flange, where the support bracket is spaced apart from the connector, and a securing bracket. A second support member includes a hook flange, the hook flange projecting from the first end of the second support member, a hook, the hook extending from the hook flange, where the hook is spaced apart from a connector bar, and a stop, the stop being positioned at about the second end of the second support member, where the stop engages the securing bracket of the first support member such that the first support member and the second support member are substantially perpendicular and are configured to support a platform.

A bracket (60) for securing a first kickboard (62) transversely of a second kickboard (54) comprises a socket (64) for receiving an end of the first kickboard and a clip (70) for securing the bracket to the second kickboard, the clip comprising a lateral extension (76) aligned with the longitudinal axis of the second kickboard for stabilizing the bracket thereon. Also disclosed are (1) a telescopic rail (46) for use in forming a guard or safety barrier for builders' trestles, staging, scaffolding or the like, comprising inner and outer telescopic parts (80, 82), in which the inner part is prevented from sliding free of the outer part in use; (2) a brace for stabilizing adjacent trestles; (3) a ladder support bracket; (4) removable safety rail components and (5) a longitudinal kickboard bracket attached to a trestle crossmember.

In one form, a bracing structure for bracing a support structure having props for ceiling formworks is provided and includes: two vertical sections joined to one another by at least one horizontal section, at least one seating element on each vertical section each having at least one seating recess for placement of a prop, whereby the opening direction of the seating recesses on the respective vertical sections point away from each other and the opening directions lie parallel to the plane defined by the vertical sections, wherein each vertical section has at least one fastener for attaching the bracing structure to the prop with at least one of the fasteners comprising at least one of the seating elements. In other forms, a fastener for attachment of a supporting structure to a prop is provided, and a method for bracing a support structure having props for ceiling formworks is provided.

A scaffold and method(s) for installing or removing such a scaffold that is constructed of at least two vertical frames and of at least two connecting elements that extend essentially horizontally, in each instance, includes at least one connecting element serving as a hip and/or back railing element, vertical supports having respective effective lengths essentially corresponding for example to the vertical distance of the attachment position for the hip and/or back railing element, and horizontal arms set onto one another to form transverse rungs, in each instance, of a ladder for allowing a person to climb up.

An adjustable scaffold base for straddling ground level obstructions, such as church pews and other fixed, ground level structures, and supporting an upwardly-extending scaffold tower thereon. The scaffold base incorporates four legs and four elevated, height-adjustable cross beams that allow a scaffold tower to be erected above the height of many fixed, ground level structures. The erected base and tower thereby allow workers to access elevated areas within high-ceilinged buildings, such for performing ceiling repairs, painting, and changing light bulbs.

The scaffold has demountable elements which can be connected to one another to make up lateral frames that incorporate vertical members, flooring platforms or planks, diagonal bracing bars, and handrail poles, and is characterized in that the said lateral frames are composed of an inverted L-shaped element and a straight pole which is connected, by a quick coupling without clearance, to the horizontal arm of the L, and is optionally complemented by further poles to make up the lateral frames, both the straight pole and the vertical or longer arm of the inverted L-shaped element being provided with quick couplings with swinging clamping pieces which are intended to receive the flattened ends of reinforcing tie rods and safety-rail poles.
