Abstract: A connecting element is provided for connecting together adjacent shuttering panels of the kind in which reinforcement strips with rows of holes provided therein are arranged at the edges of the shuttering panels and are dipsosed perpendicular thereto. The connecting element consists essentially of a curved lever arm (13) which tapers from a spigot part (17) to an end surface (18). The spigot part (17) adjoins a handle portion of the connecting element at a flange (16') defining an abutment edge (16). The handle portion is curved in essentially U-shaped manner and has a support surface (20) at the inside of its limb connected to the spigot portion (17). In operation the engagement end (18) of the lever arm is first introduced through two aligned holes in the adjacent reinforcement strips of two adjacent shuttering panels and the connecting element is then rotated about the abutment edge (16) so as to cause the spigot part (17) to enter into the two aligned bores.

Abstract: A formwork system for a concrete floor provided with a floor joist, comprising side form elements for the lateral surfaces of the floor joist, the sheathing of the side form elements being fastened to frame pieces extending perpendicularly to the longitudinal axis of the floor joist, further bottom form elements having at least one sheathing for the underside of the floor joist, and devices for interconnecting the side form elements, characterized in that at least the side form elements (1, 2, 61, 130, 131) of one side are pivotally suspended from the ceiling formwork (girder 65) and that the side form elements are interconnected by fastening means (7, 9, 148) that can be released for stripping.
