Floor pipeline damping device

Abstract

A floor pipeline damping device is characterized in that a pipeline penetrating through a floor hole is fixedly sleeved with a pipe pad through a fastening assembly, a shell covering the pipe pad is arranged outside the pipe pad and above the floor hole, a plurality of spring sets are installed between the shell and the pipe pad, and each spring set comprises two spring dampers which are symmetrically and obliquely arranged; and a bottom pad is arranged between the shell and a floor, an L-shaped spiral is clamped at the floor hole, and one end of the L-shaped spiral penetrates through the hole, the bottom pad and the shell to be connected with a fixing nut, so that the shell and the bottom pad are relatively fixed to the floor. Most horizontal vibration force generated when a house vibrates is absorbed by spring shock absorbers, and the rest horizontal vibration force is converted into horizontal friction force to be transmitted to the floor, so that the influence on the floor is extremely limited; and lower vertical vibration force is mostly absorbed by the bottom mat, so that the floor cannot be damaged. By means of the floor pipeline damping device, buffering and protection of the pipeline can be effectively guaranteed, and the floor can be protected against secondary damage.

Description

technical field [0001] The invention relates to a device installed at the hole of the floor to damp the vibration of the pipeline passing through the floor. Background technique [0002] When pouring on the building floor, in order to reduce the vibration during the pumping process of the pump pipe, it is usually necessary to install a shock absorber at the pipe position. The existing floor pipeline damping device includes a shell covering the outside of the pipeline and a spring installed between the shell and the pipeline, and a plurality of horizontally arranged springs are distributed around the pipeline. The installation of this device needs to pre-embed expansion bolts at the openings reserved on the floor, and then fix them on the floor through expansion bolts. When vibrating, the deformation of the spring is used to achieve shock absorption and buffering. [0003] Although this kind of floor pipeline damping device can achieve a certain degree of shock absorption, i...

AI Technical Summary

Problems solved by technology

[0003] Although this kind of floor pipeline damping device can achieve a certain degree of shock absorption, it is extremely inconvenient to pre-embed the expansion bolts, and it is easy to cause secondary damage to the floor; in addition, the springs are plugged around, which has poor installation firmness and low shock absorption capacity. Poor, can not effectively transform the vibration force in the vertical direction, and a large part of the vibration force in the horizontal direction will still be transmitted to the floor through the expansion bolts, resulting in damage to the floor concrete
