The system includes: first and second tower legs with first and second rosette attachment connectors; a first landing beam mountable between the first and second tower legs; first and second landing beam support connectors connectable respectively to the rosette attachment connectors; at least one building support connector for connecting the first landing beam to the building structure; third and fourth tower legs with third and fourth rosette attachment connectors; a second landing beam mounted between the third and fourth tower legs; third and fourth landing beam support connectors for connecting to the third and fourth rosette attachment connectors; and at least one strut member for connecting the first landing beam to the second landing beam.

The invention relates to a bridge that is for use with a scaffolding standard. The standard may comprise of an elongate pipe to which there is secured at least one rosette of a kind that presents a plurality of apertures about the pipe at which a connection to said standard can be established by other scaffolding components. The bridge is capable of connection to said rosette at at least two said apertures, said bridge allowing a scaffolding component to be secured thereto to be positioned and supported by said bridge at a location not catered for by any aperture of said rosette.

The present invention relates to a wind turbine with a concrete tower wherein the tower comprises a plurality of sections formed by segments a platform system comprising a plurality of platforms, wherein the platform system is configured to allow access to junction areas between sections wherefrom optionally, the execution of joints between adjacent sections may be carried out, the platforms situated inside the tower once erected being detachable, stackable and transportable.

An extendible lateral support arm having at least two elongate arm members coupled together and displaceable relative each other. The first arm defines a first end of the extendible arm. The second arm defines a second end of the extendible arm. The distance between the first end and the second end is variable. The first end presents a first head that can engage a building structure. The second end presents a second head that can be secured to an adjacent structure.

The invention relates to a scaffold support (10) comprising: a bracket (20) fixed to the wall surface (3); a screw axis member (30) having one end coupled to the bracket (20) and a male screw portion (31); an outer pipe (40) in which the other end portion of the screw axis member (30) is inserted and has a female screw portion (42) being screw-coupled to the male screw portion (31) of the screw axis member (30); a pipe rotary shaft (50) on the center of the end surface (43) of the outer pipe (40) having a polygonal head (51).

A scaffolding has a coupling which can be mounted at a connection location. The connection location in this instance has a recess in the form of a through-recess in which an angular portion of the coupling can be at least partially introduced. The angular portion engages partially behind the connection location. The coupling may have a half-coupling so that a simple connection to a scaffolding pipe, in particular for connecting to a facade, is produced. A method for connecting the scaffolding to such a coupling is also taught herein.

The present application relates to a sealed and integrated climbing scaffold, comprising a hollow frame structure, a plurality of mechanical arm devices, a plurality of climbing fulcrums, a lifting system, and a construction operation platform structure; wherein, the hollow frame structure includes an inner guide rail and an outer guide rail, the inner guide rail and the outer guide rail are capable of sliding relative to each other; at least two of the mechanical arm devices are fixed on the outer guide rail, at least two of the mechanical arm devices are fixed on the inner guide rail. When implementing the sealed and integrated climbing scaffold of the present application, it improve the level of mechanization and automation in lifting platform of high-rise construction, improve the efficiency of construction, save the workforce, realize standardization and modularization, effectively protect the internal lifting system and decline equipment failure rate.

A scaffolding bracket anchors a first vertical scaffolding pole of a scaffolding to a building faade. The bracket has at one end a clamp in order to grip the first scaffolding pole. The clamp can be locked in its closed position. A spring element urges the clamp into the closed position of the clamp with a spring force. In order to actuate the clamp, the bracket can have a first sleeve with a slotted guide by means of which the first sleeve can be transferred from the closed position into the open position of the bracket. The slotted guide may be designed in such a way that the bracket can be locked in the closed position. Furthermore, the clamp can have at least one projection for engaging in the first scaffolding pole in order to allow a particularly secure fastening of the bracket to the first scaffolding pole.

A bracket scaffold for arrangement on a curved surface of a structure includes a first securing element arranged on the structure. The bracket scaffold has an end-side first coupling element which is, in particular in a limited manner, pivotably arranged on a first carrier of the bracket scaffold. A rotation axis of the first coupling element preferably intersects with the support location of the first coupling element on the first securing element. The pivot radius of the first coupling element describes in particular a concave pivot arc on the first carrier. The rotation axis is located from the first guide preferably in the direction of the free end of the first coupling element. Extension torques in the articulation, which is formed by the first guide, are minimized by the bracket scaffold being pulled away from the structure.

A facade scaffold includes an inner pole, an outer pole and a scaffold cross-bar between the inner and outer poles. A hollow pole portion of the inner pole has a first receiving through-aperture for a coupling for the attachment of a scaffold holder. A maximum distance between the first receiving through-aperture and a top side of the scaffold cross-bar is no more than 300 mm. The first receiving through-aperture is arranged below the top side of the scaffold cross-bar, or is realized above the top side of the scaffold cross-bar as a first elongated hole. The longitudinal axis of the first elongated hole is aligned parallel to the pole longitudinal axis of the hollow pole portion. The invention simplifies and accelerates the operation of assembling a scaffold holder on a scaffold and for a two-pole scaffold holder allows a passage height under the scaffold holder to be increased.
