Description

Technical Field

[0001] The utility model relates to the technical field of communication infrastructure construction, in particular to a quick-install expansion pole. Background Art

[0002] The pole in the communication project is a pole body for hanging communication antennas. Commonly used poles are basically installed by fixed counterweight or vertical pole fixing. The fixed counterweight method uses concrete or steel structure as a weight to stabilize the pole body, and the vertical pole fixing method mainly uses chemical anchor bolts or expansion bolts to connect and fix the communication pole to the building.

[0003] In the related technology, when communication antenna equipment is installed for the first time, a pole is first built on the building. When additional antennas need to be added later, but there is no space on the original pole to mount the new antennas, there are generally two solutions: one is to build a new pole; the other is to replace the original antenna on the pole by combining antennas when the frequency band range, antenna model and signal coverage will not be affected.

[0004] With the current large-scale construction of 5G and 700M base stations, the number of antennas required for each site has increased. Antenna combining is limited by technical conditions and cannot be carried out in some scenarios. The addition of new poles requires more floor space in the building, affecting the original structure of the building. In addition, there is noise during the construction process, which is likely to cause property problems such as complaints from owners or opposition from surrounding residents. Utility Model Content
