Description

Technical Field

[0001] The utility model belongs to the technical field of concrete, and more specifically relates to a portable infiltration steel fiber concrete vibrating fork. Background Art

[0002] With the development of modern concrete technology and the rapid development of construction technology, people have put forward higher and higher requirements for cement-based composite materials. Compared with ordinary plain concrete and reinforced concrete, steel fiber concrete (SFRC) has excellent toughness, but its improvement in crack resistance and tensile strength of concrete is limited. The reason is that the fiber content of SFRC is too low to improve the crack resistance and tensile strength of concrete. Slurry Infiltrated Steel Fiber Concrete (SIFCON) can be considered as a special type of steel fiber concrete. The volume content of steel fiber in SIFCON can reach 27%. The energy absorption capacity of slurry infiltrated steel fiber concrete is much greater than that of ordinary reinforced concrete, with a difference of 3 orders of magnitude. At the same time, it has higher ductility and crack resistance and spalling resistance. It is mainly used in structures that bear harsh dynamic loads or are explosion-resistant, earthquake-resistant, and impact-resistant, such as highways, air raid panels, military explosive warehouses, anti-war command posts, and underground missile silos.

[0003] In the prior art, great difficulties are often encountered when pouring mortar-infiltrated steel fiber concrete. Since the mortar needs to be infiltrated into the steel fiber skeleton in the formwork, the steel fiber skeleton is often too dense and the agglomerations between the steel fibers are difficult to disperse, making it difficult for the mortar to completely wrap the skeleton, resulting in a large number of defects in the molded product, which has a great negative impact on the mechanical properties.

[0004] The utility model patent with the patent number CN202122957953.5 and the name of "A steel fiber concrete vibration mixing device" discloses a steel fiber concrete vibration mixing device, which includes an upper equipment platform, a mixing barrel, a support rod, and a support system; the upper equipment platform is fixed to the support system through the support rod, and a steel fiber disperser, a drive motor, a pulley, a feed port, and a water inlet are installed on it; the bottom of the mixing barrel is fixed to the support system through a shock-absorbing spring, which includes a barrel body, an internal spiral agitator, and a vibrator at the bottom. The top of the barrel body is provided with a water inlet, a feed port, and a steel fiber addition port. The side wall of the barrel body is provided with a cleaning port and a discharge port at the bottom; the support system includes a support platform, a support column, and a movable pulley. The device uses the spiral stirring blades in the mixing barrel and the bottom vibrator to form a dual vibration mixing system, and cooperates with the steel fiber disperser to make the steel fiber distribution more multi-directional and avoid the steel fiber agglomeration, so that the steel fiber concrete has better performance. At the same time, since the mixing barrel is a fully enclosed device, it can effectively control the dust in the production area and improve the production environment.

[0005] However, although this technical means can improve the production environment and avoid the clumping of steel fibers, it is difficult to ensure that the steel fiber skeleton is densely stacked, so that the mortar can evenly wrap all the steel fibers and eliminate a large number of cavitations in the gaps between the steel fibers. The defective rate of cast-in-place steel fiber concrete formed by this vibration device is high, wasting a lot of resources. Utility Model Content
