Core segment for concrete forming apparatus

A core segment for molding equipment used in forming concrete parts which are provided with at least one projecting element, particularly a climbing element, such as a climbing iron, stirrup or the like, which during a forming process is cemented from the inside into the concrete parts which are to be formed, the core segment comprising:

• a wall portion having an inside face, a plurality of apertures having upper and lower edges and housings for supporting the projecting elements;
• clamping means associated with said housings for clamping the projecting elements;
• a clamping drive associated with and engaging said clamping means;
• and
• reinforcing ribs provided on said inside face of said wall portion and extending inwardly from and transversely to said wall portion, said clamping means including associated clamping devices and a common clamping frame located on said wall portion, said housings for the projecting elements and said associated clamping devices being located on said common clamping frame, said clamping means further including guide means for said clamping frame so that, upon actuation of said clamping drive, said clamping frame is guided for movement between a release position and a closed position in a direction parallel with said wall portion, said wall portion having a shape, and said clamping means further including at least one facing plate, one said facing plate being provided for each of said apertures, disposed on said inside face of said wall portion and having a shape corresponding to the shape of said wall portion at least in the region of a respective aperture, each said facing plate having a surface area sufficiently large so that in said closed position of said clamping frame said facing plate entirely covers said aperture, sealing it off tightly, said clamping frame has two vertical sides;
• and vertical guide flanges marginally disposed on said vertical sides of said clamping frame and engaging said guide means on both said vertical sides.

A core segment for molding equipment used in forming concrete parts which are provided with at least one projecting element, particularly a climbing element, such as a climbing iron, stirrup or the like, which during a forming process is cemented from the inside into the concrete parts which are to be formed, the core segment comprising:

• a wall portion having an inside face, a plurality of apertures having upper and lower edges and housings for supporting the projecting elements;
• clamping means associated with said housings for clamping the projecting elements;
• a clamping drive associated with and engaging said clamping means;
• reinforcing ribs provided on said inside face of said wall portion and extending inwardly from and transversely to said wall portion, said reinforcing ribs being directly adjacent to said upper edges of said apertures and having a lower face extending substantially at a right angle to said wall portion, said lower face forming a flat supporting face for a projecting element;
• and centering parts projecting from said supporting face of each said reinforcing rib, said centering parts being directed substantially at a right angle to each other forming an angles member having two arms, one arm of said angled member constituting means for centering a back of a projecting element which is to be cemented in, while the other arm of said angled member forms a lateral centering means, and upon movement of the core segment into a release position, both arms of said angled member move inwardly and away from the projecting element thereby releasing it.
