Abstract: The invention relates to industrial scaffolding comprising vertical supports, which can be interconnected by means of horizontal bars. Plates, which extend on a horizontal plane, can be hooked onto the bars to create an accessible working surface. When the plates are fitted, edge areas of the latter overhang the base body of the plates in such a way that a bar running parallel to an edge area is partially covered by said edge area.

Abstract: The invention relates to a slab formwork system comprising a plurality of formwork elements (98) which have on their underside girders (2) which can be coupled to heads (28) of vertical supports (90), in which slab formwork system the head of a vertical support has a lifting lock (44-51; 87) fixing a girder of a formwork element in the vertical direction. In addition, the head of a vertical support has fixing elements (52-66) which prevent a movement of the grider in its longitudinal direction.

Mutual obstruction of the turnbuckle devices neighboring wedges is thus avoided.

Abstract: A slab formwork system is disclosed having a plurality of formwork elements which have first hook members at their lower side for establishing a hook connection with second hook members provided at upper end sections of vertical supports. The first and second hook members are designed to establish the hook connection, on the one hand, when the formwork elements and the vertical supports extend parallel or obliquely to one another and such that pivoting of a formwork element is possible, on the other hand, while maintaining the hook connection, into such a position in which the formwork element and the vertical supports include an angle of approximately 90°. The formwork element can be coupled, prior to the pivoting, with a railing member extending substantially perpendicular to the formwork element. A method for the preparation of a slab formwork system of this type is also disclosed.

The mounting of the turnbuckle device is thus made easier.

Abstract: A formwork system comprises an outer formwork, an inner formwork and an opening box-out. The opening box-out is rigidly connected to the outer formwork. The opening box-out can be reduced or enlarged in size by hinging a movable frame to its rigid inner frame. In the erected state of the formwork system, the opening box-out projects into an opening of the inner formwork. The opening of the inner formwork corresponds to the size of the recess to be formed on a concrete body. The inventive formwork system permits concreting of different wall thicknesses without changing the formwork system. Fitting of the opening box-out into a double-headed formwork can be omitted. Recess sizes and contours can be made more exact since the adjustable opening box-out is pressed on the inner edge of the opening in the second formwork shell.

Abstract: A dismantlable, multi-story facade scaffold is formed of at least four vertical support elements and floor plates and railing elements which are mounted thereto. An additional scaffold story is erected by coupling an additional vertical support element to an already existing one and pivotally attaching one end of a railing element thereto at a location above where the floor plate for the next story will be placed. The other end of that railing element is pivotally attached to another vertical support element. This other vertical support element is then raised, thereby pivotally moving the rail element relative to the respective vertical support element until the rail element is in a horizontal position and the vertical support element is in the vertical position. The other vertical support element is now attached to the upper end of a corresponding vertical support of the lower scaffold story.

Abstract: A hook strap comprises a transverse arm formed as a ribbon for abutment on an top flange on a formwork girder. The ends of the ribbon are provided with hook-shaped retainers for engagement below parts of a waler and tension elements for fixing the hook strap. The ribbon has a small thickness to prevent obstruction of the elements bordering the top flange and the upper surface of the top flange. The hook strap may be mounted at any location of a formwork girder or of a waler to interconnect formwork girders and/or connect formwork girders to a waler.
