The battery mould is used for the vertical, simultaneous production of slab-shaped precast concrete elements with 5-sided formwork-smooth surfaces
What does this product have to offer?
The battery mould is used for the vertical, simultaneous production of panel-shaped precast concrete parts with 5-sided formwork-smooth surfaces. Battery mould contains several concreting pockets suspended in a frame for this purpose (therefore also called pocket battery).
These concreting chambers consist of formwork panel and bulkhead wall as a demarcation to the neighbouring pouring compartments. To absorb the hydrostatic pressure during concreting, the formwork chambers are braced together with the bulkhead walls between a fixed tensioning wall (end panel) and a movable tensioning wall. Battery formwork enables the cost-efficient production of complex and extremely high-quality concrete components with high visual requirements and minimal geometric tolerances.
All variants of battery formwork basically consist of a number of identical, parallel partition bulkheads, between which the filling compartments for the later precast concrete part are located. The filling chambers are closed off on the underside by mould bottoms and on the sides by mould end walls. The concrete is poured from above.
The construction with a fixed initial clamping wall in combination with several movable formworks and a movable end clamping wall is called mono construction. In the duplex construction (double battery), the fixed centre bulkhead is located between the movable shell elements and the two movable end bulkheads.
B.T. innovation GmbH develops customised battery mould; including assembly and commissioning. The number and size of the concreting chambers is individually coordinated. Formwork surfaces up to a maximum dimension of 12m x 4.5m can be produced in one piece without seams or joints. The steel panels are specially rolled for steel formwork smooth formwork surfaces, finely levelled, blasted and ground according to the agreed Rz roughness
Access to the open concreting chambers as well as demoulding are easy due to the BT construction. The chambers are closed and opened mechanically or electrically. A robust and low-maintenance technology ensures the bracing of the individual formwork panels.
The side shuttering can be swivelled, which facilitates the shutter removal process. The MagFly® AP system magnet with the proven MagFly® technology for easy positioning and alignment of formwork and magnets simplifies stop ends, window and door recesses. With an adhesive force of 22,000N and a mass of only 5.40 kg, it has the best adhesive force-to-mass ratio in its class worldwide.
Battery moulds originally became popular in the late 1960s and early 1970s – but it is the increased use of F5 and F6 concretes and self-compacting concrete (SCC) in recent years that have significantly increased the use of battery moulds worldwide.
For accelerated production processes, BT Innovation has patented a removable concreting chamber, the Butterfly Formwork®. After only about 4 hours (at a strength of 3-8N/mm²), the precast elements can be removed from the battery together with the formwork and stored outside the battery to harden. The battery is immediately free for the next concreting.
