Edge connection producing method for precast concrete walls in e.g. industrial building construction, involves tightening clamp bolt and reinforcement plate in such manner that concrete walls are connected by pre-stressing

摘要

The method involves casting in tie bars (18-24) into an edge region of a precast concrete wall, where the edge region is grabbed by a clamp bolt and a reinforcement plate. The clamp bolt and reinforcement plate are fused into an adjacent another precast concrete wall, and a groove formed between the concrete walls is encapsulated with grout. The clamp bolt and reinforcement plate are tightened in such a manner that the concrete walls are connected by pre-stressing. Two parallel reinforcement bars of the tie bars are connected with a common beam.
