[0002] In the production of precast beams, in order to speed up the concrete vibration effect, in addition to using a vibrating rod vibrator, an attached vibrator is usually installed outside the side form of the precast beam. The attached vibrator uses the high-frequency vibration generated by the vibration of the vibrator itself to drive the concrete vibration, making the precast beam concrete more compact.

[0003] In the prior art, for example, there is a utility model patent with patent number 201820667637.X, which discloses an attached vibrator bracket device, which is composed of a base, an upper limit device, and a lower limit device. The base is connected to the template, and the side panels of the base are provided with template stiffening rib connecting grooves. The upper limit device is arranged at the upper end of the base, and is composed of a pull rod limiting rotating nose, a T-bolt pull rod, a gasket and a nut. The lower limit device is arranged at the lower end of the base, and is composed of a lower limit U-shaped beam and a connecting steel column. It is a card slot type structure, and the slot width is the thickness of the lower limit plate of the attached vibrator.

[0004] However, due to the vibration of the precast beam side mold, a lot of noise will be generated, which will make the workers in the precast beam production plant uncomfortable and easily fatigued. In severe cases, it will lead to hearing loss, even tinnitus and deafness, which seriously violates the concept of green construction. Based on this, it is necessary to study a sound absorption device for the attached vibrator. Utility Model Content
