<p>Device for joining two adjacent form elements, in concreting formwork, incorporates a bar and a wedge unit to clamp this firmly. The latter is led, lengthways displaceably, with the aid of a guide component with a cutout for insertion of the bar which is to effect clamping connection. As the wedge is moved lengthways its interval from the form plane is varied. The wedge unit is led in the sidewalls (2) of the cutout in the guide component (1). When form elements are stacked one on top of another, the top surface (5) of this guide component forms the bearing surface for form elements on top of it. The wedge units may be shaped in such a way that they never protrude beyond this top surface. One or more of the recess sidewalls (2) may be fitted with a sloping guideway (7), which may be in the form of a groove, or a projection on the guide component. The connectors do not hinder stacking, but permit the bar to be thrust through to any extent desired.</p> |
