Battery mould
BT innovation developed the patented Butterfly Formwork®, turning the battery mould into a Butterfly Battery®. You can find more information here
All variants of battery moulds 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 compartments are closed off at the bottom by mould bottoms and at 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 moulds and a movable end clamping wall is called mono construction. In the duplex construction method (double battery), the fixed middle tension wall is located between the movable formwork elements and the two movable end tension walls.
B.T. innovation GmbH develops customised battery moulds; including assembly and commissioning. The number and size of the concreting chambers is individually coordinated. Forming surfaces up to a maximum dimension of 16m x 4.5m can be produced seamless and butt-free in one piece. 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 is easy due to the BT design. The chambers are closed and opened mechanically or electrically. A robust and low-maintenance technology ensures the clamping of the individual formwork panels.
The side formwork can be swivelled, which facilitates the demoulding process. The MagFly® AP system magnet with the proven MagFly® technology for easy positioning and alignment of formwork and magnets simplifies shuttering, window and door recesses. With a holding force of 22,000N and a mass of only 5.40 kg, it has the best holding 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 has significantly increased the use of battery moulds worldwide.
Accelerated Construction: For accelerated manufacturing 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 for curing. The battery is immediately free for the next concreting operation. Find out more about the butterfly formwork here.
