Bailey beam fixing device and method for suspending pipeline

Abstract

The invention discloses a Bailey beam fixing device for suspending a pipeline. The device comprises a steel plate, embedded steel bars, four groups of steel bar connecting piece mechanisms and four groups of steel sleeve pieces; the four groups of steel sleeves comprise eight steel sleeves; an upper end of an L-shaped rods and an upper end of a straight rod are connected with the steel sleeves atthe corresponding positions in a matched mode through external threads; a shaft sleeve is fixedly welded to one end of the lower portion of the L-shaped rod; the lower end of the straight rod is inserted into the shaft sleeve at the corresponding position; a fastening nut is installed on the surface of the straight rod below the threaded shaft sleeve in a matched mode; the straight rod is fixedlyconnected with the L-shaped rod at the corresponding position through the fastening nut. The Bailey beam is good in safety, welding on the Bailey beam is not needed, and the Bailey beam is not damaged; after bearing the load of the Bailey beam, the embedded steel plate is uniformly transmitted to the concrete under the steel plate, so that the stability and reliability of the supporting surface ofthe Bailey beam are improved, the Bailey beam is more stable and reliable under the suspension working condition, the installation is simple, the operation is easy, the requirement on the skill of workers in the whole process is low, the material acquisition is simple, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of Bailey beams, and more specifically relates to a Bailey beam fixing device and a fixing method for suspending pipelines. Background technique [0002] During the construction of open-cut subway stations, Bailey beams are often used to suspend the pipelines that cross the station and are difficult to relocate. When suspending, the Bailey beams are fixed on the crown beams at both ends, and then the suspended pipelines are suspended with booms or wire ropes. . [0003] In the past, steel bars or steel rings were mostly pre-embedded on the crown beams, and the Bailey beams were welded with steel bars or fixed with wire ropes. In actual operation, welding and fixing would cause certain losses to the Bailey beams, but fixing them with wire ropes would not The complete consolidation of the Bailey beam will cause the Bailey beam to shake easily, and the installation method is also relatively cumbersome.
