Locking system to hold insulation walls together, e.g. for a cold storage room, has a locking bolt structure in slits at the facing ends to anchor them together for a rapid erection on site

摘要

The system to lock room wall sections together has closing and locking bolts (4) for walls (13) with an insulating layer (2) between two outer plate layers (1). A passage channel (6) for the locking bolts is through the wall. The insulating layer a slit structure (8) at right angles to the bolt passage channel, open to the connecting side. Closure and mounting plugs (9) are fitted to the outer plate layers in both sides of the bolt passage channel, with a bolt section between their inner ends (19) aligned with the slit, as a hook (15) with a hub (115) which can swing and be clamped. The connecting surface of the neighboring wall section has a slit (18) aligned with the slit in the first wall section and open towards it, with a locking bolt (4) across the path of the hook (15), as an inserted pin to grip through, anchored to the outer plate layers of the wall being locked in place.
