Abstract

The invention relates to the field of prefabricated type concrete structures, and particularly discloses a preparation device of a directional steel fiber reinforced concrete prefabricated component.The preparation device comprises a bottom supporting frame, the supporting frame is a rectangular metal frame, two first sliding rails in the horizontal direction are arranged on the upper surface ofthe supporting frame, and the two first sliding rails are symmetrically arranged; a coil is arranged on the first sliding rails, pulleys are fixed to the bottom of the coil, and the coil is slidably connected to the first sliding rails through the pulleys; two symmetrically-arranged steel supports are placed at the bottom of the supporting frame, the upper surfaces of the steel supports are located in the internal space of the coil, the steel supports are located between the two first sliding rails, a non-metal formwork is placed on the steel supports and penetrates through the coil, and vibrating rods are arranged on the coil; and a current exchanger is further arranged beside the supporting frame and electrically connected with the coil. The preparation device aims to solve the problem that tensile strength of a concrete matrix is insufficient due to steel fiber random distribution and low unidirectional reinforcement efficiency in an existing steel fiber concrete component.

Description

technical field [0001] The invention relates to the technical field of prefabricated assembled concrete structures, and specifically discloses a preparation device and method for directional steel fiber reinforced concrete prefabricated components. Background technique [0002] Concrete is widely used in practical projects because of its aggregates can be obtained locally, components are easy to form, and it has the advantages of high compressive strength and durability. However, its own shortcomings such as high brittleness, low tensile strength and easy cracking limit its application in tensile-based load members. Compared with ordinary concrete, steel fiber reinforced concrete mixed with appropriate amount of steel fiber has greatly improved its tensile strength, flexural strength, wear resistance, impact resistance, fatigue resistance, toughness, crack resistance and explosion resistance. . However, the distribution of steel fibers in ordinary steel fiber reinforced co...
