Abstract
The invention relates to a process for the production of cellular or foamed, cast concrete bodies that are reinforced with metallic reinforcements, and to a reinforcement support frame for use in the production of cellular or foamed, cast concrete bodies that are reinforced with metallic reinforcing bars.
Claims13
A process for the production of cellular or foamed cast concrete bodies or block that are reinforced with reinforcements made of metals, comprising the following processing steps:
- (a) providing at least one reinforcement with at least one rigidly integrated supporting bar wherein each of the supporting bars comprises an upper end that projects beyond the reinforcement by a definite length and is optionally provided with a predetermined breaking point;
- (b) positioning the reinforcement for being held by a reinforcement support frame, the frame including at least one clamping component;
- (c) gripping or clamping the end of the supporting bar by means of the clamping component such that the reinforcement is rigidly attached to the reinforcement support frame while dangling from the reinforcement support frame;
- (d) applying a rust-proofing agent to the reinforcement;
- (e) dipping the reinforcement which is suspended from the reinforcement support frame, into a casting mould, the mold being open at the top for receiving fresh concrete slurry;
- (f) allowing initial setting of the fresh concrete slurry to form a cast concrete block, and holding the reinforcement by means of the reinforcement support frame during the initial setting;
- (g) separating each upper end of each of the supporting bars from the reinforcement;
- (h) optionally cutting and partitioning of the cast concrete block into cellular or foamed cast green concrete bodies;
- and
- (i) hardening the cellular or foamed cast concrete bodies or block.
