Self-supporting advancing equipment with compression-proof base plate

摘要

The invention relates to self-supporting advancing equipment with a compression-proof base plate for local production of single-span girders or continuous girders lying one behind another, in particular of reinforced or prestressed concrete bridges. After production of a construction section, the complete equipment is advanced by the length of a section to be used again. To move forward, known equipment has to fold down parts of the shuttering in order to produce a free passage for the columns standing in the way. High costs arise from the mechanical outlay and the work-intensive operation. In order to simplify the equipment, a compression-proof base plate is arranged, which is connected rigidly to all other parts of the equipment. On advancing, the base plate slides between the construction section just erected and the column, the load of the girder being introduced via a sliding bearing into the pressure plate and from there via a second sliding bearing directly into the column. The load of the equipment is likewise introduced directly into the column via the lower correspondingly enlarged sliding bearing. The arrangement of the equipment, of the construction section and of the column is shown in cross-section in Fig. 6. <IMAGE>
