Vibrating device for precast concrete stairs

Abstract

The invention provides a vibrating device for precast concrete stairs. The vibrating device for the precast concrete stairs is applicable to stair dies. The device comprises at least one vibrating unit assembly, wherein the vibrating unit assembly comprises a lifting part and a vibrating part; the lifting part comprises a vibrating pedestal, vibration absorbing air bags which are arranged at the left side and the right side of the vibrating pedestal, and an air compressor; the vibration absorbing air bags are correspondingly connected to the air compressor through pneumatic hoses; the vibrating part comprises a vibrating table board and a vibrating motor; the vibrating motor is mounted on the lower end surface of the vibrating table board; the upper ends of the vibration absorbing air bagsare connected to the vibrating table board through bolts, and the lower ends of the vibration absorbing air bags are connected to the vibrating pedestal through bolts. The device is simple in structure, and reasonable in design; concrete can be smoothly charged, and air in the concrete can be effectively exhausted, so that the strength of formed precast stair components can be ensured. The deviceis good in vibrating effect, and small in noise; the working intensity of workers can be effectively reduced; the working efficiency is improved; the massive production is conveniently carried out; and the device is worthy of popularization.

Description

technical field [0001] The invention relates to a vibration device, in particular to a vibration device for prefabricated concrete stairs. Background technique [0002] The use of prefabricated staircase components for assembly construction has the advantages of saving labor, overcoming seasonal influences, and facilitating perennial construction. However, air is easily mixed in during the manufacturing process of prefabricated staircase components, resulting in a decline in the strength of prefabricated staircase components. In order to solve the above problems, in the production of the existing prefabricated staircase components, the concrete is generally poured into the mould, and then the air is discharged manually by vibrating with a hand-held concrete vibrator. However, this method requires multiple vibrations at multiple positions of the staircase mold to remove the air. Not only is the labor intensity high, the work efficiency is low, and it is not easy to operate in...

Problems solved by technology

However, this method requires multiple vibrations at multiple positions of the staircase mold to remove the air. Not only is the labor intensity high, the work efficiency is low, and it is not easy to operate in large quantities, but also requires the staff to stand above the mold for operation. certain security risks
