Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an external hanging rack for construction engineering. Background Art

[0002] The existing announcement number CN 221073422 U discloses a construction pylon. When the pylon is in use, the pylon body is directly fixed to the side of the wall. The protective plate provides excellent protection, allowing construction workers to work smoothly on the top of the pylon body. When the telescopic device is used, the threaded rod is rotated to retract the damping rod, which removes the retaining plate from the retaining slot, preventing the retaining plate from affecting the rotation of the round rod. By rotating the round rod, the gear and the serrated block engage, driving the connecting bar to slide on the surface of the pylon body, thereby effectively driving the telescopic plate to slide inside the side of the pylon body. When the round rod does not need to rotate, the threaded rod is rotated out of the protective plate, and the spring drives the damping rod to return to its original position, and the retaining plate is inserted into the retaining slot. This can effectively increase the usable area of the pylon body and reduce the number of construction pylons. However, when adjusting the construction area of the pylon, the operation steps are complicated and the construction area can only be extended on one side, which brings inconvenience to use.
