A standing seam mounting bracket and a method of using two or three to provide attachment points along a standing seam roof is provided. The standing seam mounting brackets enable complementary use of commonly-owned equipment for enabling roof maintenance and construction. The standing seam mounting brackets may be used in concert with roof jacks, roof ladders, scaffolding members and the like that are commonly owned by most contractors so as to facilitate safe and easy horizontal and vertical movement along the sloped roof.

Implementations of a roof platform configured for use on an inclined roof are provided. In some implementations, the roof platform is adjustable so that the platform thereof can be positioned in a horizontal orientation even when mounted on a pitched (or inclined) roof. In this way, equipment (e.g., an air conditioning unit, satellite dish, solar panel(s), etc.) may be positioned on the platform and thereby the roof of a building. In some implementations, the roof platform assembly may comprise a platform that includes two leg couplings affixed to a front side thereof, four tubular legs stabilized by braces, and four pitch adjustable feet configured to be affixed to a roof. Another example implementation of the roof platform assembly may comprise a platform that includes four leg couplings, four tubular legs stabilized by pairs of adjustable braces, and four pitch adjustable feet configured to be affixed to a roof.

A building assembly system for fabricating a multi-story building is described, wherein the building includes a vertical support core arranged on a base. Lift jacks are arranged between a top portion and a bottom portion of the vertical support core, and a reusable bridle is suspended from the plurality of lift jacks and slidably arranged on the vertical support core. A floor plate is assembled onto the bridle at an assembly level that is proximal to the base. The plurality of the lift jacks are operable to lift the bridle and the assembled floor plate to a design elevation on the vertical support core, and are operable to lower the bridle to the assembly level on the vertical support core after the floor plate has been secured to the vertical support core at the design elevation.

A safety system (1) for scaffolding on a construction site having a plurality of elongate scaffolding elements (5) connected together by a plurality of couplers (7) to form a scaffolding structure (2). One or more elements connected to one or more base plates supporting the structure on a surface. At least two safety monitors (10) spaced apart about said structure. Each said monitor having a power source, a sensor and a transmitter. The sensor sensing movement in said structure and transmitting a signal to a receiver to indicate movement in the structure.

The invention relates to a scissor-type securing element (1) comprising two hooks (2, 3) pivotably connected together by a rotary shaft (4), a distal part being defined in each hook (2, 3) on one side of the shaft (4) and a proximal part being defined on the other side of the shaft (4), each distal part being provided with a tooth (21, 31) and each proximal part being provided with a penetrating slot (22, 32). According to the invention, the securing element has an insertion configuration (P1) in which the hooks (2, 3) are superposed, and a securing configuration (P2) in which the teeth (21, 31) are in a more separated position and the hooks (2, 3) project so as to remain retained in an inner support surface (51) of a case (5). The securing element (1) comprises a shackle (6) provided with: a ring (61) for supporting the load, two ring ends (62, 63) and a key (64) supported by the two ends (62, 63) and inserted into the slots (22, 32), the ends (41, 42) of the shaft (4) projecting laterally and the ring ends (62, 63) being provided with a housing (65) having a form complementary to the ends (41, 42) of the shaft (4), such that in the insertion configuration, each end (41, 42) of the shaft (4) is inserted into a housing (65).
