Abstract

The invention provides a prefabricated hybrid fiber concrete replaceable coupling beam and a preparation method thereof. The prefabricated hybrid fiber concrete replaceable coupling beam comprises a coupling beam body, coupling beam anchoring parts are arranged at the two ends of the coupling beam body, and the coupling beam anchoring parts are connected with wall columns through connecting bolts;and the connecting beam body comprises hybrid fiber concrete and beam body reinforcing steel bars, and the hybrid fiber concrete wraps the outer sides of the beam body reinforcing steel bars. The hybrid fiber concrete is obtained by mixing cement, fly ash, silica fume, sand, a water reducing agent, steel fibers, polyvinyl alcohol fibers and water. The coupling beam body is formed by pouring the hybrid fiber concrete and the beam body reinforcing steel bars, and the toughness, bending resistance and impact resistance of the coupling beam concrete are effectively improved by doping steel fibers; by doping the polyvinyl alcohol fibers, the toughness, ductility and fracture resistance of the coupling beam concrete are effectively improved, and then the coupling beam body has good anti-seismicproperty; and the coupling beam anchoring parts are connected with the wall columns through the bolts, the coupling beam can be replaced, the manufacturing process is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a prefabricated hybrid fiber concrete replaceable connecting beam and a preparation method thereof Background technique [0002] The coupling beam is a beam structure connecting the wall piers on both sides. When it is subjected to an earthquake, it will yield before the shear wall; It plays a vital role and needs to have higher stiffness, bearing capacity, ductility and better energy dissipation capacity; the existing small-span-to-height ratio coupling beams have poor seismic performance, and the general coupling beam structure cannot be replaced , Even beam repair after the earthquake is more difficult. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present invention provides a prefabricated hybrid fiber-reinforced concrete replaceable connecting beam and its preparation method to solve the problem that the exi...
