Vibrator rod special for hollow floor slab concrete

Abstract

The invention discloses a vibrator rod special for hollow floor slab concrete. The vibrator rod includes a motor, a connection pipe and a vibration rod head; the vibration rod head includes a housing, a rubber shock absorption pad, a bearing support, a hollow rotation shaft and a solid rotation shaft; the housing includes a lower housing body and an upper housing body, and a second eccentric block is fixedly connected with the hollow rotation shaft; the solid rotation shaft is coaxial with the hollow rotation shaft and passes through the hollow rotation shaft, the solid rotation shaft is fixedly connected with a first eccentric block, and the mass of the first eccentric block is larger than that of the second eccentric block. The vibration rod head includes the upper housing body and the lower housing body, a traditional housing is divided into two vibration cavities, the second eccentric block is located in the middle of the upper housing, and the first eccentric block is located in the middle of the lower housing; the upward vibration amplitude and downward vibration amplitude of the vibration rod head can be different, the lower housing body can stretch into the bottom of a hollow-floor-slab light mold in the construction, the problem that the concrete at the bottom of a hollow floor slab is not tamped is solved, and the reinforcing bar revealing, honeycomb and surface pitting phenomena occurring on a large area of the concrete at the bottom of the mold are reduced.

Description

technical field [0001] The invention belongs to the field of building hollow floor slab construction, and in particular relates to a special vibrating rod for hollow floor slab concrete. Background technique [0002] Concrete construction in the construction field requires that the surface of the concrete must not have defects such as exposed ribs, honeycombs, and pockmarks that affect the appearance quality. During the construction process, it must be vibrated strictly in accordance with the requirements to ensure that the concrete is compact; however, many buildings currently use sound insulation when designing. For hollow floor buildings with good effect, light molds are installed in the hollow parts of the floors. The distance between the bottom of the mold and the formwork is too close. At present, it is difficult for ordinary vibrating rods to reach the bottom of the mold during the construction process, resulting in insufficient vibration of the concrete in this part, ...

At present, it is difficult for ordinary vibrating rods to reach the bottom of the mold during the construction process, resulting in insufficient vibration of the concrete in this part, resulting in Exposed tendons, honeycombs, and pockmarks appear in large areas of the concrete at the bottom of the mold, which seriously affects the appearance quality of the concrete and the function of the building
