Description
Technical Field

[0002] As a key process in concrete construction, vibration operation directly affects the quality of subsequent construction. Among them, applying a higher vibration frequency before the initial setting of concrete can remove the air entrained during pouring, compact the concrete structure, and thus improve the compressive strength of concrete. However, the traditional concrete vibration process mainly relies on manual participation, and there are problems such as high labor intensity, poor working environment, and difficult quality control. Insufficient vibration time (under-vibration) causes a small amount of bubbles inside the concrete to be discharged, resulting in low density; too long vibration time (over-vibration) causes concrete stratification and segregation, resulting in separation honeycombs, pockmarked pores, beam and slab cracks, and exposed steel bars in the concrete forming quality problems. Current research on mechanical vibration of concrete mainly reflects the mechanical vibration of concrete without steel mesh (plain concrete), and it is difficult to achieve standardized vibration of concrete under the steel mesh.

[0023] The utility model realizes the intelligent vibration of concrete under the steel mesh. The existing intelligent vibrating device fixes the vibrator at the end of the mechanical arm. The above assembly method makes it difficult for the vibrator to pass through the steel mesh to vibrate the concrete below. Even if the vibrator at the end of the above device can be immersed in the concrete mixture under the steel mesh, there are still two major problems. The first major problem is that the freedom of the mechanical arm is limited, and it is difficult to ensure that the end vibrator is inserted in a vertical posture. During operation, it is also easier to collide with the steel bars; another major problem is that due to the space limitation of the steel mesh, the depth of the vibrator fixed at the end of the mechanical arm inserted into the concrete mixture is limited. The utility model solves the above problems.
