Vertical (European type) battery moulds (BM) for fabricating of single-layer wall slabs and solid (no-void) floor slabs. The vertical battery mould have two sides L and R and consists of the stationary middle, row and moving lateral parts. Either the entire VBM or one of the sides (L or R) can operate.
The lateral (moving) parts are equipped with strain bars and a hydraulic cylinder, and serve as a drives drawing the entire filled battery into the machine. The battery moves along guide rails. Chambers are handled in sequence. The moving part is driving itself thus opening the first chamber. After demoulding and extraction of product the chamber is closed and these actions are then repeated for the second, third and the subsequent chambers. Then the other operation can be done at the same sequence. The operating distance between the chambers is equal to 1200 mm. This ensures the fast readjustment of the machines of this type and presents their key feature.
Using magnetic sides allows to mould various wall slabs (with window and door openings) or solid floor slabs. Two products can be simultaneously formed on a single working surface owing to the vertical dividing sides, which are fastened into the slots of the lower side and to the battery mould on the top. The dividing sides are provided with special silicone sealant, which prevents leak of concrete slurry leakage and ensures straight edges of the product. The sealant material choise is governed by its thermal resistance since the temperature of the thermal oil reaches 140-190°С. The readjustable lower side allows to mould products of 120, 140, 160, 180 and 200 mm thickness. With such versatility battery mould is able to fabricate wall slabs for various design series.
For concrete consolidation, there suspended vibrators are installed in the upper and lower chord inside of each chamber. The chords operate independently, which prevents gravel chippings from sinking in the lower part of the concrete product. The vibrators are maintained using maintenance hatches.
For the BM's of such type we specially developed the curing conditions control system (CCS). Owing to such decision, the complete steam curing cycle was reduced to 8 hours vs. the conventional 12-hours cycle.
Centralized control of hydraulic, vibration and steam curing is implemented from the panel located in the middle part of the BM. The touch panel is provided with information on all parameters of the BM displayed for each chamber separately, including the steam curing mode and its settings, the state of the hydraulic cylinders, vibration and positions of the screens (open/close). The stand-alone vibration-control cabinet is installed on the service platform which is a part of the BM's basic equipment.
