In all formwork applications, tie-rods connect two opposing panels withstanding the concrete pressure. However in some cases, it is impossible to use tie-rods. For example; at dams, when there is no space for the opposing panel to be placed, when walls are too thick, at stop - ends of thick walls, at stop - ends of thick slabs. In these cases TRIANGULAR SOLDIER which is assembled on formwork is used.
Concrete pressure is transfered by means of single sided system components to the ground anchors which withstand these forces with the angle of 45°.
