Connecting bolt 207 is installed on plate base 204 and is threadedly connected to the threaded hole in connecting base plate 211.

[0037] The hinge structure between the connecting seat 223 and the rotating seat 222, i.e., the protrusion 205 rotates in the connecting groove 203 through the hinge shaft 206, can accommodate the angle deviation that may occur in the upper and lower support legs 210 during adjustment.

[0038] Installation of formwork and scaffolding for boiler construction at this power plant: Insert the hinge joint 112 at the lower end of the upper frame rod 110 into the hinge seat 111 at the upper end of the lower frame rod to achieve hinge connection.

[0042] When the boiler template is tilted or curved, the hinged structure between the support rods 110 allows the template connecting frame 100 to adapt to curved or tilted boiler templates. Rotating the adjusting rod 202 on the screw adjusting seat 220 drives the screw 221 to rotate. Since the screw 221 is threadedly engaged with the screw connection hole 212 of the support leg column 210, the rotation of the screw 221 changes its screw depth in the screw connection hole 212, thereby adjusting the relative distance between the upper and lower support leg columns 210 and achieving precise height adjustment. At the same time, the hinged structure between the connecting seat 223 and the adjusting seat 222 can accommodate the angular deviations that occur in the upper and lower support leg columns 210 during adjustment.
