Description

Technical Field

[0001] The present application relates to the technical field of pipeline installation, and in particular to a cable bridge structural seam compensation structure. Background Art

[0002] The cable tray is usually composed of several sections connected by bolts, and the whole can be regarded as a rigid body. When crossing the structural joints of buildings, there will be a certain elevation difference due to the deformation of the floor slabs on both sides of the structural joints, as well as some uneven settlement after completion. If compensation is not performed, the entire bridge may be deformed and the cables may be damaged. The "General Design Specification for Building Electrical and Intelligentization" issued in 2023 clearly stipulates that compensation devices should be installed at the cable tray across the structural joints. At present, the telescopic sections made of flexible materials are more commonly used, but their installation is more complicated, and there will be long-term stress after deformation. They are usually only effective for horizontal deformation, and their vertical resistance is weak. Their cost is also usually high. Utility Model Content
