NOZZLE FOR POURING FIBER-REINFORCED CONCRETE

摘要

The present invention relates to a nozzle for pouring fiber-reinforced concrete capable of preventing the reinforced fiber contained in an unset fiber reinforced concrete from massing and of dispersing a reinforced fiber by poured in a form with the desired direction. The present invention provides, as a nozzle (100) for pouring fiber-reinforced concrete connected to a concrete mixer, a nozzle for pouring fiber-reinforced concrete that has a space therein by composed of an upper surface, a vertical side surface, and a lower part which is opened and makes an outlet, has a front surface (15a) and a back surface (15b) among side surfaces vertically arranged which have shapes that widen from the upside toward the downside, has left and right side surfaces among side surfaces vertically arranged which have trapezoid shapes that narrow from the upside toward downside, and makes the reinforced fiber to vertically fall without arranged in the horizontal direction or massing when the fiber reinforced concrete is poured by having, in any one or both of the front surface plate (15a) and the back surface plate (15b), a protrusion (17) which guides the direction of falling by the collision of reinforced fiber (10) mixed in concrete material and is provided in a protruding state when the fiber reinforced concrete is poured through the nozzle (100).
