this operation is repeated as many times as required by the length of railing needed for the scaffold once the safety railing is assembled the remaining elements which make up the scaffold are assembled at this level such as platforms baseboards horizontal bars diagonal bars if required side bars etc the bars which are part of the safety railing remain in this level as part of the definitive safety railing that is they remain as structural elements of the scaffold itself naturally the recovered auxiliary elements or railing bases are used in assembling the provisional safety railing for the following level the conventional means referred to for connecting the auxiliary elements to the bars in assembling the railing consist of rods which are attached to the auxiliary elements as a complement of the description being made and in order to aid a better comprehension of the characteristics of the invention the present descriptive memory is accompanied by a set of drawings as an integral part of the same where for purposes of illustration and in no way meant as a definition of the limits of the invention the following is shown 0020 fig1 is a perspective view of the general structure of a scaffolding level during preparation for assembling the provisional railing of the higher level 0021 fig2 is a representation similar to the previous one where the first auxiliary element or railing base is mounted on the corresponding frame 0022 fig3 is a representation similar to the previous ones where the provisional assembly of a first segment of the provisional railing.
