Abstract

The invention relates to the field of prefabricated concrete structures, and specifically discloses a preparation device for directional steel fiber reinforced concrete prefabricated components, which includes a support frame at the bottom, the support frame is a rectangular metal frame, and the upper surface of the support frame is provided with two horizontal bars. A first slide rail, two first slide rails are symmetrically arranged; a coil is arranged on the first slide rail, a pulley is fixed on the bottom of the coil, and the coil is slidably connected to the first slide rail through the pulley; the bottom of the support frame is placed with Two symmetrically arranged steel supports, the upper surface of the steel support is in the inner space of the coil, and the steel supports are located between the two first slide rails, a non-metallic formwork is placed on the steel support, the non-metallic formwork passes through the coil, and the coil is set There are vibrating rods; there is also a current exchanger next to the support frame, and the current exchanger is electrically connected to the coil; the present invention aims to solve the problem of random distribution of steel fibers and low efficiency of one-way reinforcement in the existing steel fiber reinforced concrete components, which lead to the failure of the concrete matrix. The problem of insufficient tensile strength.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete structures, and specifically discloses a preparation device and a preparation method of an oriented steel fiber reinforced concrete prefabricated component. Background technique [0002] Concrete is widely used in practical engineering due to its advantages of high compressive strength and durability, which can be used locally for its aggregates, easy forming of components, and high compressive strength. However, it has shortcomings such as high brittleness, low tensile strength and easy cracking, which limit its application in load-bearing components mainly based on tensile strength. Compared with ordinary concrete, the steel fiber reinforced concrete prepared by adding an appropriate amount of steel fiber has greatly improved tensile strength, flexural strength, wear resistance, impact resistance, fatigue resistance, toughness, crack resistance and explosion resistance. . Howeve...
