The main type of equipment in any production of precast concrete structures are rotary vibrating tables. Equipping the production with pivoting or tilting vibrating tables is an excellent investment in universal equipment, both for a large plant that produces hundreds of thousands of square meters of housing, and for a small enterprise that is just starting its way to the market.
On the tables can be made a wide range of reinforced concrete elements:
Tiltable vibrating tables are made in the form of a stable profile welded structure. Stiffness in the longitudinal direction provides a thick-walled steel profile, which is a kind of table stiffener. In the transverse direction, the table is reinforced with steel wing-shaped profiles, reliably welded to the main rib.
The table is mounted on a hinged frame, fixed to the base, and can be rotated on an axis with the help of telescopic cylinders, thereby facilitating the dismantling of products.
The surface of the table is covered with high-quality sheet steel with a thickness of 10 mm and polished. PBS company manufactures table surfaces from European steel grades “DOMEX” / “SSAB”, due to the highest quality, ease of subsequent operation and maintenance of such surfaces. Permissible deviation from the plane of 1.5 mm by 3 meters of the measured length in the lowered state. Permissible load on 1 square meter of table surface – up to 1000 kg. Each table can be optionally equipped with a Wacker Neusson concrete compaction system that provides first-class quality and durability.
For heat treatment of the molded product in the design of the vibrating table there is a thermal contour located directly below the table surface.
Steam, hot water from the heating system or heated oil can be used as a heat carrier.
The basis of the quality of the released reinforced concrete element is, above all, the observance of the correct technology of compaction of fresh concrete. Vibrating tables are equipped with Wacker Neuson external vibrators – a recognized leader in vibration technology.
Vibrators are located on the table in such a way as to exclude the possibility of unsealed zones on the products. Each vibrator is connected to the frequency converter separately and independently of the others. It is possible to adjust the frequency and amplitude of vibration on each vibrator separately. In case of failure of the vibrator, it can easily be replaced without affecting the work of others.
The compaction process is fully automated and controlled by a radio remote control.
If necessary, it is possible to equip the table with additional stationary flaps on the side planes. This solution will allow a more economical use of removable borosnaku on magnets. As standard, the vibrating table is offered with a stationary lower side up to 400 mm high.
When dismounting, side boards must be folded back to release the product before demoulding.
Telescopic cylinders and a pumping station with a flow dividing system ensure perfect synchronous operation and reliability.
In accordance with the plan of the device of the end formwork, it is necessary to place the side equipment on the table and securely fix it with the help of magnets.
Then it is necessary to lubricate the finished form with a special release agent and perform work on the device of the reinforcement cage. After the final control of the correctness of the assembly of the formwork and reinforcement cage, the vibrating table is ready for concreting.
The concrete mixture must be evenly laid on the table surface, periodically including external vibrators to ensure a high-quality process of compacting concrete.
After the concreting is completed, the upper plane must be smoothed out, and the vibrating table should be covered with a tent of heat insulating material. This will provide the best conditions for the ripening of concrete and shorten the time to build strength.
After a set of necessary strength by concrete, partial dismantling of the formwork is carried out in order to free the product before excavation.
Then, using hydraulics, the table leans into the stripping position and the finished product is removed from it.
