Abstract (en)
[origin: WO9316854A1] Described is an apparatus (1) for making concrete construction elements (100) having hollow channels (104) extending in the longitudinal direction thereof. Such an apparatus (1) comprises a first concrete-pouring element (20) for making a bottom layer (110) for the construction element (100) to be made; vibrator shoes (31) for compacting the concrete of the bottom layer (110); a second concrete-pouring element (40) for pouring a second concrete layer (120) onto the bottom layer (110); a vibrator plate (51) for compacting the concrete of the second layer (120); and bars or pipes (61) extending from the vibrator shoes (31) to beyond the vibrator plate (51) for ensuring that the hollow channels (104) are made in the constuction element (100) to be made. According to the invention, this apparatus (1) is improved in that between the vibrator shoes (31) and the bars or pipes (61) there is arranged a flexible filling piece (200) having a gradually extending contour.
