Description

Technical Field

[0001] The utility model relates to the technical field of overhead steam pipeline fixing brackets, in particular to a heat-insulating overhead steam pipeline fixing bracket. Background Art

[0002] In the design process of overhead steam pipelines, fixed brackets are generally designed and manufactured according to national standard drawings. This type of bracket generally welds one side of four wing plates to the main pipeline. The wing plates are set on both sides of the channel steel standing on the concrete pier to limit the steam pipeline. This type of pipeline fixed bracket forms a thermal bridge due to the contact between the wing plates and the channel steel, which can not only dissipate part of the steam heat into the air, but also accelerate the plasticization of the concrete due to the thermal conductivity of the channel steel, thereby reducing its service life.

[0003] Through prior art search, it was found that the Chinese invention patent announcement number is CN 214064000U, which discloses an overhead steam pipe sliding bracket, which belongs to the technical field of overhead steam pipe brackets. The bracket includes a reinforced concrete foundation, an embedded steel plate fixedly embedded in the top surface of the reinforced concrete foundation, a polytetrafluoroethylene plate laid on the embedded steel plate, and a plurality of sets of screws and nuts. In the bracket, the polytetrafluoroethylene plate and the embedded steel plate are fixedly connected by a plurality of sets of screws and nuts, thereby ensuring that the pipeline support always slides relative to the polytetrafluoroethylene plate, and the friction force is small, avoiding the movement and falling off of the polytetrafluoroethylene plate, and effectively improving the safety of the overhead steam pipeline. However, the bracket cannot block the thermal bridge between the air and the steam pipeline, and cannot play a role in heat insulation. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
