LOCK FOR FORM PANELS CONNECTION Russian patent published in 2005 - IPC

FIELD: building, particularly to connect adjacent frame panels used to erect cast-in-place reinforced concrete structure.

SUBSTANCE: lock has load-bearing bracket and rotary rests with chamfers. Lock is also provided with two additional equal-arm levers rotary connected one to another from one end so that another lever ends may rotate relative rotary rests pivotally installed on load-bearing bracket. Bracket contacts with lower surfaces of form panel profiles and is spaced from side surfaces thereof. Axis of two additional equal-arm levers connection may be displaced relative load-bearing bracket and may pass through kinematic dead point. Rotary rest chamfers have additional sidepieces to contact with side surfaces of form panel profiles.

EFFECT: increased reliability of panel connection, reduced necessary force for lock opening and improved service conditions.
