Table forms for concrete walls and floors
Tilting tables and fixed tables for one-sided fair-faced concrete walls or floors
A Construx table is a rigid steel frame with a 8mm or 10mm steel sheeting. The steel sheets can be up to 16m x 4,5m in 1 single piece without joint. These long and wide plates are rolled specially for being used as formwork surfaces. They are sandblasted and polished on an automated grinding machine in order to obtain a smooth finish.
The level of smoothness depends on the customers’ requirements. Larger sizes are possible if needed, the table will be manufactured in parts and the individual sections will be connected, welded and grinded in the precast factory.
In order to demould wall panels without damaging the edges, the panels need to be tilted before they are removed off the table. By doing so they can also be stored vertically. The use of a hydraulic tilting table is the most appropriate way to tilt the panels.
A tilting table consists of a rigid top structure which is fixed onto a tilting articulating base frame. With the use of perfectly synchronised hydraulic rams the top structure can be tilted up to 80°. By using multi-stroke cylinders there is no need for recesses in the floor.
In case vibrators are used, the top structure will be subdivided into a table form and a tilting frame, with vibration absorbers fitted in between both. This is done to minimise the loss of vibration energy.
In order to use the table’s full width, we supply individual supports along the length of the table, which can be used as an extra work surface if the side forms need to sit at the edge of the table. This means that a 4m wide table can be used to cast 4m wide elements.
The sides of the table can be equipped with fixed, detachable, tiltable or adjustable side-forms. These adjustable forms are easy to use and can be fixed at any height. The most common range is 200mm, from 100mm to 300mm, continuously variable. Full steel or timber side forms can be fitted onto the table by means of box magnets.
If the customer is not going to use self-compacting concrete, the table can be equipped with vibrators, operating at either normal or high frequency.
In the latter case, a frequency converter will be used to adapt the vibration energy according to the shape and the sizes of the elements sitting on the table.
As an option the tables can be insulated and equipped with heating pipes underneath the top part of the table. The insulation plates can also be fixed on the factory floor or onto a steel casing around the table.
The heating pipes sit right underneath the top part, through the lateral profiles. All tubes are interconnected and the positions of inlet and outlet are determined after consulting the customer.
