The special combined mold for the iron tower foundation protective cap of the present invention is composed of 4 L-shaped molds with the same structure and 4 connection locks. The 4 L-shaped molds with the same structure form a rectangular frame, and the surrounding edge plate is arranged on the upper edge of the rectangular frame. , each L-shaped mold is provided with a rectangular lock on the two free ends of the wall plate, the rectangular lock is a hollow structure, the shape of the lock hole on the upper end of the rectangular lock is "L", and the "L" shaped lock hole It is divided into a vertical keyhole part and a horizontal keyhole part. The horizontal keyhole parts of the keyholes on two adjacent L-shaped molds are connected, and the locking plate surface of the connecting lock is rectangular. There are two The protrusion that matches the vertical lock hole part of the lock hole, the distance between the two protrusions is equal to the distance between the vertical lock hole parts of the "L" shaped lock hole on two adjacent L-shaped molds, on the upper end surface of the lock plate surface Welded round pipe sections serve as handles.

The panel of the L-shaped mold in the special combination mold for the protection cap of the iron tower foundation of the present invention is welded with a rectangular lock. In the application process, only four pieces of L-shaped molds need to be placed on the base of the tower foot, and the combination mold can be connected through the connecting lock. It is very convenient and fast to complete the assembly of the combined mold. Using this special combined mold for the iron tower foundation protection cap does not require carpentry or other professionals to assemble. It can be quickly and fixedly assembled by ordinary labor, so that the work efficiency is higher and the cost is reduced. . And the poured protective cap has a smooth surface, which effectively improves the construction quality.
