Abstract:
1. A prop head for a concrete ceiling, a concrete ceiling formwork and a concrete ceiling formwork prop, the formwork prop having a longitudinal axis, the prop head comprising: an end piece having a first end structured to face the concrete ceiling and a second end structured to face the formwork prop, said end piece having a longitudinal axis extending in an elongated direction of said end piece, wherein, in a position of use of the prop head, said longitudinal axis extends substantially vertically and perpendicular to a plane of the concrete ceiling formwork; a skid forming a segment of a circle, said skid being integral with said second end of said end piece, wherein a center of a circle defined by said segment of said circle of said skid is disposed proximate to said first end of said end piece; a profile element in which said skid is guided, said profile element structured and disposed for cooperation with an end of the formwork prop facing said second end of said end piece, wherein said profile element and said skid define a hinge mechanism, said longitudinal axis of said end piece thereby pivoting together with said skid relative to the longitudinal axis of the formwork prop into hinged positions of said hinge mechanism, wherein a load-introducing center of gravity formed by said first end of said end piece in said hinged positions essentially lies on a line encompassing the longitudinal axis of the formwork prop; and fastening means cooperating with said hinge mechanism to lock said hinge mechanism in said hinged positions, said fastening means having screws disposed, structured and dimensioned to load and firmly clamp said skid within said profile element.
