[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-3, a steel bar processing shed for ventilation shaft construction, including a shed assembly 1, a threaded ring 3 is installed on the top of the shed assembly 1, and the inner side of the threaded ring 3 is threadedly connected with a screw rod 4, the shed assembly 1 includes a first plate body 101, and one side of the first plate body 101 is connected to a second plate body 102, the second plate body 102 is connected to the first plate body 101 through a hinge 103, and a threaded hole 2 is opened on the inner side of the second plate body 102, and a threaded support rod 5 is threadedly connected to the inner side of the threaded hole 2. The shed assembly 1 forms a lifting structure with the threaded support rod 5 through the threaded hole 2. The threaded support rod 5 is manually rotated so that the threaded hole 2 is moved up and down along the outer side of the threaded support rod 5, which is convenient for individuals to complete the construction and disassembly work. The outer wall of the threaded support rod 5 is provided with a groove matching the connecting rod 7. By setting the groove, the connecting rod 7 can be easily placed, so that the threaded hole 2 can be better threaded along the outer side of the threaded support rod 5, and there will be no motion interference problem;

[0022] A telescopic support rod 6 is installed at the bottom end of the shed assembly 1, and the outer walls of the threaded support rod 5 and the telescopic support rod 6 are movably connected with connecting rods 7. The telescopic support rods 6 are distributed in three groups, and the telescopic support rods 6 are arranged on both sides in front of the bottom end of the shed assembly 1 and on one side behind the bottom end. The output end of the telescopic support rod 6 can move up and down with the shed assembly 1. The top of the connecting rod 7 is movably connected with a movable plate 8. The movable plate 8 forms a detachable structure with the shed assembly 1 through bolts. The movable plate 8 and the shed assembly 1 are connected by bolts, so that the connecting rod 7 can form a triangular support structure for the shed assembly 1 under the cooperation of the support rods. The threaded support rods Movable blocks 11 are inserted into the inner sides of the rod 5 and the telescopic support rod 6, and the end of the movable block 11 is connected to a pull rope 10, and the other end of the pull rope 10 is connected to a movable column 9.
