摘要:
A wall bracket is provided for facilitating construction work, as a surface for a person or another load. The wall bracket comprises a plurality of support structures (110) to be fastened to a wall in parallel and at a distance from one another and, resting thereon, parallel working platform frames (150) settling at a distance from one another for supporting working platforms (252, 253) comprised by the wall bracket. In the invention, the working platforms are such that the working platform comprises a self-supporting wall (261 to 267, 271 to 277) and that at least an end area of the self-supporting wall is provided with an overlap area (L) for resting on an adjacent working platform.

The invention relates to a climbing cylinder (10) for a self-climbing shuttering in civil engineering which is provided to permit passage along climbing tracks (22) on a wall (12). The climbing cylinder (10) has a fixing at one end for an anchor point on the wall and, at the other end, a ratchet (30) is provided on the climbing cylinder, which can be made to engage with the climbing rail such as to support the climbing rails (22) and also displace the same. The climbing cylinder (10) can be fixed to an anchor point on the construction or to a climbing bracket (18).

Module for cantilevered scaffolding to be associated with elevated structures (21), such as buildings, bridges, dams or suchlike. The module comprises two base components (11, 12) and assembly and/or accessory components (14-20), able to be selectively associated with the base components (11, 12). The base components comprise a cross-piece (11) arranged substantially horizontal, and an upright (12) arranged substantially vertical and able to support lateral containing elements. The cross-piece (11) has a first seating (26), for a first assembly component (20) defining a through anchorage on a part of the structure (21), and a second seating (22e) for a second assembly component (14) defining a resting anchorage on a part of the structure (21).

A frame assembly for a temporary stairway comprises a platform (1) formed of a substantially E-shaped frame and a correspondingly substantially E-shaped auxiliary frame (2) slidingly engagable therewith. The frame forming the platform (1), and the auxiliary frame (2) can be fixed at predetermined positions so as to expand or contract the frame assembly to a desired width. Hanging means (8) are provided at the corners of the frame assembly for connecting a series of assemblies together in a stack by flexible connection means (8) to form a temporary stairway. A ladder (4) is pivotally attached to each frame assembly.

Collapsible scaffolding comprises a number of platforms (12) which can be suspended in spaced vertical array for chains (14) secured to the corners of the platform, and arranged at the top for the support of the scaffolding by a crane or a horizontally movable trolley. Additional cables (25) at each end of the platforms are each secured at the lower end to the lowest platform (13) and pass through guides (31) secured to the intermediate and top platforms (11,12) to a winch (24) enabling the platform to be quickly lifted and stacked (Fig. 2), but allowing them to be quickly lowered and erected (Fig. 4). The guides (13) provide lateral location of the stacked platforms.
