ABSTRACT:
A support device and wall for a cable duct (10) in a cavity lining floor comprises a lift-off double bottom (24) in the direction of the cable duct (10) and a prefabricated blind shuttering (28) on the opposite side. Legs (16), which stand upon the bare concrete floor (12) at regular intervals corresponding to an integral multiple of the interval (e) of adjacent depressions (34) in the blind shuttering (28), are in alignment with the depressions (34) relative to the transverse direction of the cable duct (10).
The legs are constructed as support plates (54) with vertical support rod (52) which exhibits a screw-thread at least in the uppermost region. A support profile (14) is arranged on these legs (16) with a cantilevered profile tab (32, 36) on each side as a horizontal bearing surface for the edge (30) of the blind shuttering (28) or the double bottom (24) respectively, with a profile tab (32) projecting vertically upwards and separating the double bottom (24) and the cast-in mass (26) and with a groove (48) of square or rectangular cross-section open downwards. The two side faces of this groove (48) have continuously recessed longitudinal groovings (50) which correspond to the screwthread of the support rods (52) and are mutually vertically staggered by half the pitch of the screwthread.
The screwthread of the support rods (52) is engaged in the longitudinal groovings (50) of the groove (48).
