- BWC 55-740 with an angel for negative load
BWC 55-740 is our best alternative to traditional thermal bridge breakers, or directly embedded steel profiles for supporting balconies with front columns or inclined struts.
For prefabricated balconies with column/slanted braces at the front, clamping flange for good waterproofing and with an angle for negative load. Molded cover or hole cover.
Undirected horizontal force will bend the vertical leg of the angle in the same direction as the vertical force. If possible horizontal load, the angle must be checked for the combined torque effect from both forces. BWC outer tube with the standard anchoring design is anchored for max. horizontal force FH=20kN
The system consists of several parts:
Cut-out box in the deck: If you choose to use this, the cut-out box is molded into the slab, and must be anchored with the specified anchoring reinforcement.
Outer tube: Alternatively, this can be molded directly into the slab, or threaded into an already established recess box. This model is equipped with a clamping flange system against GU, which keeps the water on the outside. If you choose to cast the outer tube directly into the tyre, we recommend that it is taken with our rubber cuff (700x700 mm) which takes up any casting deviations, and is glued to the GU.
Inner tube with an angel: This is the part that connects the cover and the balcony element. This comes in several variants. It is most commonly combined with a cast-in balcony box (BWC 55-4), or it comes with a welded-on angle. If a balcony or corridor is to be cast in place, the inner tube is extended, and it is reinforced directly on the inner tube.
All parts are made of steel S355, and hot-dip galvanized.
