Oriented steel fiber arrangement device and steel fiber concrete manufacturing method

Abstract

The invention discloses an oriented steel fiber arrangement device and a steel fiber concrete manufacturing method. An air blower, an adsorption switch, a tight adsorbing switch, an air pipe, a steelfiber adsorption disc, adsorption needles and an oriented magnetic field belt are included. The air blower is utilized for driving gas to generate attraction force, the gas pipe is used for transmitting the attraction force to the adsorption needles of the steel fiber adsorption disc, after the adsorption needles tightly absorb fiber, the fiber tends to be arranged in the same direction under theaction of magnetic force of the oriented magnetic field belt, the tight adsorbing switch is turned on, it is guaranteed that the steel fiber and the adsorption needles are fixed, then, the steel fiberarranged in the oriented manner is placed in a layer-by-layer poured concrete surface layer, and steel fiber concrete in which the steel fiber is arranged in the oriented manner is formed. The oriented steel fiber arrangement device and the steel fiber concrete manufacturing method have a series of preparing advantages that operation is simple, and steel fiber arrangement is uniform, and the oriented steel fiber arrangement device and the steel fiber concrete manufacturing method are suitable for manufacturing of the steel fiber concrete in which the steel fiber is arranged in the oriented manner.

Description

technical field [0001] The invention relates to a device and method for making concrete, in particular to a device and method for directional arrangement of steel fibers and a method for making steel fiber concrete. Background technique [0002] Concrete is one of the most widely used and most mature basic materials in civil engineering. With the development of science and technology, the invention and application of various admixtures and fiber materials have expanded the composition and application range of concrete. Adding a certain amount of steel fiber to concrete can improve the crack resistance of concrete and ensure good ductility and durability of concrete. Compared with ordinary steel fiber concrete, the tensile strength of ordinary steel fiber concrete is increased by 40%-80%, the flexural strength is increased by 60%-120%, the shear strength is increased by 50%-100%, and the compressive strength is increased by a small amount. 0-25%, but the compressive toughnes...
