Furthermore, a group of sliding grooves corresponding to the bosses are formed along the inner wall of the sleeve.

Furthermore, a stepped hole penetrates through the center of the clamping plate, the clamping plate comprises an installation section and a connecting section which are of an upper layer structure and a lower layer structure, the large-diameter section of the stepped hole is located in the connecting section, and the small-diameter section of the stepped hole is located in the installation section;

the inner wall of the small-diameter section of the stepped hole positioned at the mounting section is provided with a group of grooves corresponding to the lug boss, and the large-diameter section of the stepped hole positioned at the connecting section is connected to the sleeve through threads.

Furthermore, two threaded holes for bolts to pass through are symmetrically formed in two sides of the lower portion of the bent sliding seat, and the bolts penetrate through the threaded holes and then abut against the lower surface of the flange plate on the I-shaped steel.

Furthermore, the boss is a long strip-shaped structure extending along the length direction of the vertical rod.

Through the technical scheme, the utility model has the beneficial effects that:

according to the cantilever scaffold, the upright rod is not directly welded with the I-steel, but the I-steel is firstly connected with the sliding seat and then arranged in the sleeve, so that the integrity of the I-steel is ensured, the damage to the structural strength of the I-steel caused by repeated welding is avoided, the sliding seat can slide along the I-steel, the upright rod is allowed to freely select a supporting point on the I-steel and then be fixed, and therefore, the adjustment of the position of the upright rod is more flexible, and the erection operation of the cantilever scaffold is simpler and more convenient.

When the overhanging scaffold is erected, after the sliding seat on the I-steel is fixed, the upright is inserted into the sleeve and then fixed by the simple rotating clamping plate, and the upright can be pulled out by aligning the reverse rotating clamping plate with the groove and the boss during disassembly, so that the operation of installation and disassembly is simple and the construction is convenient; because the scaffold frame of encorbelmenting sets up and is high altitude construction, can directly reduce constructor's operation safety risk through the above-mentioned simple and convenient operation, suitable popularization and application.
