Damping device capable of offsetting floor slab disturbance caused by pump tube impacting

Abstract

The invention discloses a damping device capable of offsetting floor slab disturbance caused by pump tube impacting. The existing problem that a floor slab is impacted resulting in the existent of easy fatigue and damage of floor slab concrete when concrete pouring is conducted on walls, beams, slabs and columns is solved. The damping device comprises a rectangular vertical steel plate framework penetrating through a floor slab hole, a horizontal steel plate framework is fixed on the outer side wall of the rectangular vertical steel plate framework, an expansion bolt connected with the floor slab penetrates through the horizontal steel plate framework, vertical connecting plates corresponding to the side walls of the rectangular vertical steel plate framework one by one are arranged on theinner sides of the rectangular vertical steel plate framework, the part between each vertical connecting plate and the corresponding inner wall of the rectangular vertical steel plate framework is provided with a damping spring which is connected with the vertical connecting plate and the corresponding inner wall of the rectangular vertical steel plate framework, and rollers are arranged on the inner sides of the vertical connecting plates. By means of the damping device, the disturbance in the horizontal and vertical directions of the floor slab caused by the impacting force of a pump tube when the pump tube penetrates through the floor slab is greatly relieved, the damping effect is greatly improved, the problems of fatigue and damage of a middle layer floor slab are prevented, and theconstruction quality of floor slab concrete is ensured.

Description

technical field [0001] The invention relates to a shock-absorbing device for pumping concrete through a floor, in particular to a shock-absorbing device capable of counteracting the impact of a pump pipe to disturb the floor. Background technique [0002] During the construction of high-rise buildings, the concrete pouring of high-rise walls, beams, slabs, and columns is poured by pumping concrete. The pump pipe needs to pass through the floor slab vertically to transport the concrete to the working surface of the construction floor. [0003] The conventional construction method is to open a square hole 100mm larger than the diameter of the pump pipe on the floor. The pump pipe passes through the floor, squeeze the pump pipe and the floor with a wooden wedge, and tie the pump pipe with a steel wire to prevent the pump pipe from leaking. However, during the process of pouring concrete, the pump pipe will shake irregularly up and down, left, right, front and back for a long ti...
