Anti-seismic sliding type pipeline support

Abstract

The invention discloses an anti-seismic sliding type pipeline support. The anti-seismic sliding type pipeline support comprises six portions including a groove fixing connecting piece, a spherical reinforcing hanging rod, a square pipe crane, a U-shaped pipe crane, fastening screws and fastening nuts. An elongated cavity is formed in the bottom plate of the groove fixing connecting piece, so thatthe spherical reinforcing hanging rod can penetrate in the elongated cavity, the spherical reinforcing hanging rod can slide left and right under the action of earthquake, damage to the support and astructural body due to pipeline deformation is relieved, the lower square pipe crane and the U-shaped pipe crane are connected with each other through the fastening screws and the fastening nuts, andaxial deformation can be selectively relaxed or restrained according to engineering requirements. The pipeline support is in detachable connection, is convenient and simple to construct and high in safety factor, meanwhile, does not occupy space of a pipeline, has an excellent anti-seismic effect, and can be used for hoisting small-diameter pipelines in a comprehensive pipeline gallery or other buildings.

Description

technical field [0001] The invention relates to the field of anti-seismic design of civil engineering and mechanical engineering, and more specifically, relates to an anti-seismic support for hoisting pipelines in an underground comprehensive pipe gallery. Background technique [0002] The urban underground comprehensive pipe gallery is a public infrastructure that builds a continuous structure underground in the city and lays two or more lifeline engineering facilities such as electricity, communication, gas, heating, water supply and drainage. The comprehensive pipe gallery is buried underground and distributed in a wide area. Therefore, it will inevitably pass through sites with different geological conditions, including areas with active seismic activity. Under the action of an earthquake, the main structure of the pipe gallery will sway with the shear force of the soil layer, and then drive the pipes in the gallery to vibrate and deform. Due to the certain quality of t...

Problems solved by technology

[0003] At present, the brackets for hoisting pipes in the pipe gallery are generally reserved on the wall by connecting pieces, and the brackets are fixed on the wall later by fasteners. Fix the pipeline on the support. Although this fixing method can improve the bearing capacity of the support to a certain extent, it is inconvenient to connect and occupies the space for placing the pipeline, which restricts the deformation of the pipeline. Under the earthquake, the inertial force generated by the pipeline will all pass through the support. Transferred to the main body of the pipe gallery, resulting in greater damage
