AI Technical Summary
The existing precast hollow slab beam core mold is prone to floating during the concrete impact during the casting process. The traditional ring stirrups are not confining enough, resulting in insufficient thickness of the top slab of the precast hollow slab beam.
An adjustable precast slab beam core mold anti-floating device is adopted, which uses a combination structure of hollow square steel pipes, nuts and threaded steel bars, and is connected by welding and screws to form multiple sets of channel steel and steel plate supports, so as to effectively fix the core mold and adjust its height.
It effectively prevents the core mold from floating, ensures the stability of the core mold position during the concrete pouring process of the precast slab beam, improves the strength of the component and the ease of operation, and the material is readily available and reusable.
