Any wall formwork system involves the use of special locks. According to its mission locks are distinguished on the transmission (horizontal forces that arise in the mold and transferred truss rod); tightening and connecting the elements of the casing.

Anchoring in wedge lock rod held a wedge, and the wedge effect is increased as a result of bending of the anchor rod in place of driving the wedge. Simple wedge lock for formwork is used for small diameter rod and a small amount of effort passed. The main index of the construction of the castle is its reliability.
The comparative tests with other types of locks have shown that under static load virtually all of the locks behave the same way: hold securely hung on them the goods. Under dynamic loads directed along one of the castle gradual 'slippage' lock the profile. Wedge lock perfectly established himself in a similar situation – 'creeping' simply did not exist. Perhaps this is because, driving a wedge, there is no need reflect the persistence of the thread, as is the case when dealing with locks of an action.
