The invention discloses a hollow floorslab core mold fixing device, which comprises a bottom die plate, a plate bottom bar-mat reinforcement, a plate top bar-mat reinforcement, a group of core molds and plain concrete
cushion blocks, wherein the group of core molds are arranged between the plate bottom bar-mat reinforcement and the plate top bar-mat reinforcement, and are arranged in a matrix manner, the plain concrete
cushion blocks are arranged between the tops of the core molds and the plate top bar-mat reinforcement; the plate top bar-mat reinforcement is in bound connection with the plain concrete
cushion blocks, and is connected with the bottom die plate through a connecting piece; the cross sections of the core molds are rectangle, gaps are reserved between the bottoms of the core molds and the plate bottom bar-mat reinforcement; four vertical side faces of the core molds are all provided with
rebar fixtures, so as to clamp the corresponding core molds among the
rebar fixtures; the tops of the
rebar fixtures exceed the plate top bar-mat reinforcement, and two side faces of each rebar fixture are respectively tightly pressed on the side faces of two adjacent core molds; vertical supports are arranged among the core molds, the upper ends of the vertical supports are connected with the plate top bar-mat reinforcement and the lower ends of the vertical supports are connected with the plate bottom bar-mat reinforcement. The hollow floorslab core mold fixing device has the
advantage that the technical problems of the traditional core mold fixing method that the
workload is heavy, the integral bar-mat reinforcement rigidity is low, the core mold is easy to damage and the late repair
workload is heavy are solved.
