摘要: Apparatus for manufacturing a hollow concrete slab by a slide casting operation. The slab is formed with one or more cavities through the use of tubes of flexible material into which a pressurized medium, particularly water, is fed. The apparatus comprises a stationary base and a casting device arranged to travel in the longitudinal direction of the base. A number of parallel shaping pipes forming part of the travelling casting device and having a cross section corresponding to the desired cross section of the cavities to be formed are opened at both ends. The flexible tubes, which are fastened at their rear ends, to a pressured liquid source pass during the casting process from reels in the casting device through the pipes so as to give the cavities their final form.
