Zusammenfassung: | A vibration formwork structure capable of effectively relieving maintenance cracks at the end of a precast beam comprises a steel formwork, a flat plate vibration motor and end insertion type vibration equipment, transverse stiffening ribs and a vertical supporting frame are arranged on the steel formwork, the stiffening ribs are transversely distributed on a web formwork of the steel formwork in a welding mode, and the vertical supporting frame is arranged on the web formwork of the steel formwork. The distribution direction of the stiffening ribs is consistent with the length direction of the steel formwork, and the vertical supporting frame is connected with the steel formwork and the stiffening ribs. Flat plate vibration motors are arranged on a belly formwork on the steel formwork in a staggered mode, and end insertion type vibration equipment is arranged at the end of the steel formwork. Coarse particles can be effectively prevented from being retained in a reinforcing steel bar dense area, so that the |
