Abstract

Demountable scaffolding to support bridges and work lifting platforms, comprising columns and at least one bridge or platform that can be raised or lowered along said columns, including each bridge at least two supporting frames and including each platform a supporting frame, each frame supported by a motor assembly and a braking device serving said motor assemblies to move the respective bridge or platform up and down along a respective column and serving the braking devices for the immobilization of the same to any desired level; characterized in that the scaffolding is formed by modular elements that can be assembled together by means of releasable joining devices, each column (1) having a structure of the lattice type and being formed: by a base section ( 7) integral with a first base platform (12) mounted on wheels (13), and this first base platform (12) being mounted on a second, wider platform (14), and connected to it, removably, provided of other wheels (15) and legs (15) of adjustable height, so that each column (1) and the parts connected thereto can slide along the ground or, respectively, remain stable thereon, as chosen; by a plurality of other column sections (7a) to be installed in superposed relation on the base section (7a), said column sections (7, 7a) being triangular in their horizontal cross section, and including a vertical corner bar ( 9a) and two vertical tubular rods (9) of corners that form in their mounted state vertical guide rails to receive sliding guide wheels (36), supported by the respective frames (31), which form part of the supporting structure of each bridge (2) or platform (3), this supporting structure also comprising modular elements of lattice, supporting (46, 47a, 57b), connectable to each other in longitudinal alignment, supported each supporting structure a floor, (148), as well as parapet anterior (149) and posterior (150), each parapet being formed (149 or 150) by frames (56), the frames (56) forming each front parapet (149) being connected to the supporting elements (46, 47a), 46b and 31) by means of joints or joints comprising tubular seats intended to receive the lower ends of the columns of the lower frames (56) of the columns of the frames (56) and arranged in bodies (57) fixed to the supporting structure near the upper longitudinal front edges of the elements (46, 47a, 47b, 31), while the frames (56) forming the parapet (150) facing the building, are connected to the elements (46, 47a, 47b, 31) by means of joints or joints comprising tubular seats arranged in bodies (57a) connected to the opposite upper longitudinal edges of said elements with the interposition of telescopic connections in order to allow to vary the distance of each parapet or railing (150 ) of the building and as a result, the width of each bridge (3) or platform (2), each column element (7a) comprising a device for simultaneously introducing fastening pins of security (17 and 20) through the tongue and groove joining elements (8 and 8a) connecting the column elements (7 and 7a).
