An improvement to U.S. Pat. No. 6,003,630 comprising a method and device whereby the extension arm portion is removably attached and to the nail plate portion while attached to the exterior scaffolding portion, thus permitting a single user to take down the scaffolding easily and safely on their own without assistance. Additionally, the scaffold can now be safely lowered to the ground entirely from the building interior via a support line attached to the extension arm while it is attached to the exterior scaffolding. This improvement makes the 630 patent more efficient and much safer to use. Additionally, a spanner bracket for use with cement block or pour in place concrete walls is disclosed herein enabling a non ground-based scaffolding system in use with the 630 patent for such walls types, also permitting single user set up and removal of the scaffolding.

A scaffolding arrangement for a building outer wall, comprising a plurality of anchor bolts arranged at a distance from each other at least in the horizontal direction, including tube clamps connected to the anchor bolts, a horizontally extended rail, the rail being fixed to the tube clamps, a scaffolding as well as a connecting device for fixing the scaffolding to the rail. The connecting device provides a first coupling encompassing the rail as well as a second coupling encompassing a tube element of the scaffolding and a coupling connector for connecting the first coupling to the second coupling.

A beam assembly for a scaffold system includes a support beam configured to couple with a plurality of modular components to allow the beam assembly to be built around a variety of different sized and shaped structures. The support beam having an upper attachment mount, a lower attachment mount, and a web member extending between and interconnecting the upper attachment mount and the lower attachment mount. The support beam having a plurality of holes of differing diameters to allow for the modular coupling with other scaffolding components.

A climbing system, in particular a self-climbing formwork system, comprising at least one climbing rail which is guided on at least two climbing shoes, wherein the climbing shoes can be fastened on and/or in a cured concreting section, and wherein the climbing shoes are designed to guide the climbing rail and/or to hold it at least with respect to a climbing direction, and an actuator. The at least one climbing rail has at least a first and a second rail part, wherein the first and the second rail part are arranged one behind the other as viewed in the climbing direction, in that the first and the second rail part can each be guided and held by means of one of the climbing shoes, and in that the actuator is designed to selectively increase or reduce the distance between the first and the second rail part along the climbing direction.

A structural arrangement for securing scaffolding to a building wall. The structural arrangement includes the building wall with a recess, a faade anchor secured to the building wall and having a receptacle for accommodating at least one securing element. The securing element engages in the receptacle in the faade anchor on the one hand and in the recess in the wall on the other hand. The faade anchor provides a supporting face facing the building wall. A compensating material is provided between the supporting face and the building wall in such a manner that the faade anchor makes contact over its supporting face with, and is supported by the building wall indirectly via, the compensating material.

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 steel-structure building envelope capable of erecting a scaffold and a method for erecting the scaffold are disclosed. The scaffold is fastened to the steel-structure building envelope through two steps fastening means. A pre-embedded reinforcing steel bar is laid in each of RC slabs and extends out of the corresponding RC slab to be wound around the scaffold, serving as the first fastening means for fastening the scaffold. Locking parts are embedded into the corresponding RC slab at intervals. The transverse aluminum extrusion is disposed on an outside of the corresponding RC slab. The wall connecting rods each have a first end that passes through the transverse aluminum extrusion and is locked to the corresponding locking part and a second end configured to lock the scaffold, serving as a second fastening means for fastening the scaffold after the pre-embedded reinforcing steel bar is removed from the scaffold.

A scaffold safety device (120) has a body (122) having an engagement formation (124) configured to engage with an element (20, 72) of a scaffold assembly (10). The device (120) also has a pressure sensor (126) configured to detect when the body is disengaged from the scaffold assembly. The engagement formation includes first and second arms (128, 130) extending away from the body. The arms are separated by a cavity (134). The cavity is configured to receive a threaded rod and a tightening nut (135) of the scaffold assembly. The pressure sensor is included on one arm (128) and is configured to detect when a pressure attains a predetermined threshold value. The pressure sensor is in communication with a control board (86) which is connected to an antenna (140) on a secondary scaffold safety device (142).
