CUTTER FOR CONCRETE CORED SLAB

The utility model provides a cutter for concrete cored slabs, belonging to a construction machine. In the prior art, the cutting cost of the cutter for concrete cored slabs is high, the end faces of the hollow slab after cut is not provided with reserved steel wires, so the application is subjected to severe limitations. In the cutter for cored slabs of the utility model, a lifting motor drives a cutting board in up-down motion through a gearbox, a screw nut, a screw rod and a lifting frame; simultaneously, a vibrating motor drives a vibrator to make the cutting board vibrating transversely in high frequency, which makes the concrete crossing narrowly flowing rapidly, as a result, the cutting purpose is achieved. The cutting cost is low, and the length of the steel wires can be reserved as required. The utility model is an ideal cutter for concrete cored slabs at present.
