New process for mounting handrails in scaffolds

Abstract

The invention is applicable as a safety measure in assembling scaffolds for construction work, specifically in assembly of the railings, so that these are made to be the first component installed on the upper level, this being performed from the level where the worker is already at, so that when said worker rises to complete the scaffold a provisional safety railing is already in place. The provisional railing is put together, raised and assembled by use of an auxiliary element or railing base to which the horizontal bars are connected, element which is anchored by suitable means to the structural frame of the scaffold

1 . New assembly procedure for scaffolding railings intending, as a safety measure, that the first element assembled at each scaffolding level is a railing, this assembly being performed from the lower level, characterised in that a provisional safety railing is formed with an auxiliary element or railing base ( 1 ) joined by conventional means ( 6 ) to bars ( 2 ), said auxiliary element ( 1 ) being used to raise and gradually secure each corresponding railing segment, assembled or pre-assembled, to the respective structural frames of the scaffolding, where auxiliary element ( 1 ) are attached to frames ( 3 ) by means of lugs ( 9 ) and ( 10 ) provided in the latter, and by auxiliary element ( 1 ) having an inverted U-bar hook which plays within lug ( 9 ) and a further U-bar near its end which laterally embraces auxiliary element ( 1 ) and is prolonged as a plate which fits in lug ( 10 ) of the frame.  
     
     
         2 . New assembly procedure for scaffolding railings as in  claim 1 , characterised in that the worker partially puts together the provisional safety railing at the floor where it is being assembled, attaching matching ends of bars ( 2 ) of the railing to the conventional attachment means provided in auxiliary element ( 1 ), leaving the other ends free to later raise the unit manually, securing the auxiliary element to the scaffolding structure and repeating this process for a further one to which previously are attached the free ends and the ends of the group of bars which make up the next segment of the railing, and so on until the required length of railing is obtained, followed by assembly of the remaining elements which make up each level of the scaffold, so that once the installation is completed the bars of the provisional railing are removed from their attachments to the auxiliary element and definitively attached to the frames in order to create the fixed railing, while auxiliary element ( 1 ) are recovered to begin putting together, raising and assembling the provisional safety railing for the following floor above.  
     
     
         3 . New assembly procedure for scaffolding railings as in previous claims, characterised in that auxiliary element or railing base ( 1 ) shows two segments which form an open angle between them, so that the lower segment, which after said auxiliary element is attached to the frame is divergent, includes the means of attachment to said frame, while the other segment, which after assembly is left parallel to the frame, includes the means for securing bars ( 2 ).
