Abstract

A girder element (1; 21; 31; 41; 53-57) for concrete formwork comprises a girder (4) for receiving external forces (10), a tension rod (5) extending behind the girder (4) and at least one lengthwise adjustable tensioning device that is interposed between the girder (4) and the tie rod (5), the local distance between the girder (4) and the tie rod (5) being adjustable by means of said tensioning device. The invention is characterized in that the lengthwise adjustable tensioning device is configured as a lengthwise adjustable compensation device (6; 6a, 6b) which is motor driven to adjust the length of the compensation device (6; 6a, 6b). A measuring device is used to determine the position (x) of the girder (4) in the area of the compensation device (6; 6a, 6b) relative to a desired position (xs). A control device (12) is used to adjust the length (L) of the compensation device (6; 6a, 6b) depending on the position (x) of the girder (4). The girder element according to the invention allows the precise and cost-effective manufacture of any concrete structures.
