Disclosed is an arrangement including a staircase as well as walkway systems. The staircase includes a transitional member, and the walkways incorporate grate supports in order to facilitate the connection to adjacent structures. The arrangement also utilizes angled members which are configured with a reinforced flange existing in a dimension that has higher load requirements than the other flange. A novel step configuration is also disclosed.

A scaffold post integrated with height-adjustable U-shaped support includes: a circular unthreaded support post integrally formed with an external threaded section, a U-shaped support base disposed around the external threaded section and capable of sliding relative along the support post. The spindle nut is disposed around the external threaded section and located below the U-shaped support base. A connecting spigot, with two sets of fastening through-holes formed to use the support post at different heights. At least one locking pin is used wherein fastening through-holes are formed at two ends of the spigot; where one end of the spigot is inserted into the respective end of the support post provided with fastening through-holes; after the fastening through-holes are aligned to the respective fastening through-holes, the locking pin is inserted through the holes to connect the support post and connecting spigot.

A scaffolding assembly adapted to be releasably attached to an elongate support member such as an overhead pipe. The scaffolding assembly has a split collar and a platform assembly adapted to be releasably attached to the split collar. The split collar comprises at least two segments which can encircle the pipe and be secured to one another. The platform assembly which includes a platform deck has a connector formation which extends laterally outwardly from the deck to an extent that it can engage a receiving formation on the collar assembly and thereby attach the platform assembly to the collar assembly.

A flexible device mounting kit allows to securely attach a sensor or another device to an arbitrary surface, including a surface that is very uneven. The kit includes a scaffolding assembly which includes a scaffolding guide and scaffolding teeth attached to the guide in a way that allows some of the teeth to move relative to the guide when the bottom of the teeth is pressed against uneven surface. When the assembly is pressed against the surface, the positions of the teeth adjust, forming, together with the surface, a cavity into which a gluing compound can be filled. A device mount to which a sensor (or another device) can be attached is pressed into the gluing compound before the gluing compound solidifies. As the gluing compound securely connects the sensor mount to the surface, the device can be securely placed within the mount regardless of how uneven the surface is.

A means for solving the problem is characterized in including: a frame body including a pair of longitudinal beams, a pair of lateral beams, and four coupling members disposed between respective end portions of the longitudinal beams and respective end portions of the lateral beams so as to rotatably connect the longitudinal beams and the lateral beams on the same plane, two or more intermediate beams bridged between the longitudinal beams at a predetermined interval; and scaffolding boards bridged between the longitudinal beams and supported by at least one of the intermediate beams, the number of the scaffolding boards being larger than the installing number of the intermediate beams by one.

Various implementations described herein are directed to a scaffold bracket. In one implementation, the scaffold bracket may include a mounting bracket having a first face and a second face opposite of the first face. The scaffold bracket may also include a first scaffolding node attached to the first face and configured to couple to a first member. The scaffold bracket may further include a second scaffolding node attached to the first face and configured to couple to a second member.

A platform and a kit therefor. The platform and the kit comprises quad-chord trusses attachable end-to-end and having connector members intermediate thereof, and further comprising beams attachable at their ends to the connector members so that a beam attaches two parallel trusses. A truss comprises first and second pairs of chords which are foldable for storage and transport and unfoldable to use for erection of the platform. A track lies between the upper chords to allow movement of bolts along the track into position to attach for insertion into decking apertures for attachment of the decking. The kit also includes a sturdy and reliable and easy to use tie-up mechanism and railing along the platform perimeter which is quickly and easily attachable and reliable.
