The PCA circular column formwork has been developed for the fast and efficient realization of circular columns. This website uses technical, analytical and third-party cookies, in order to send you advertisements in line with your preferences. The modular holes of all the main components offer multiple options for connecting accessories, rncofrados important fact especially in matters of safety e.
Since ever truss structures have been proven the most efficient solution for long spans. Bridge sections of variable height and with a maximum weight of t per segment can be done. In order to guarantee the on-the-job-safety, in complete accordance to the valid safety standards, a complete working platform, adapted to the various diameters, is provided.
The truss solution facilitates an erection in any units, always according the specific crane capacity and conditions in-situ. In cases of spans of 18m up to 24m the HEA system is used. encofradoz

In the case of geometries differing from the classical rectangular shape, inserted wooden stencils cut to size are used. The corresponding panels are complete with sockets for pour tubes and with windows for control and inspection.
The use of standard connection plates, which quantity is reduced to a minimum of different types, as well as only one single type of connection facilitate the assembly with high frequency of repetitive works. The several Formworks for Columns of ULMA facilitate the realization ulm your ambitious constructions using precise products with the guarantee of an optimal result corresponding to your specific project requirements. Using the provided wheels it is possible to move the formwork rapidly and independently of any crane-use.
ulmx On request, a pneumatic system of vibration can be supplied. All the components can be left assembled during all working stages and the stage of moving or lifting. The inner formwork-unit is moved completely independently. The one initially assembled formwork may be used throughout the entire works as a complete and remaining ejcofrados unit; if necessary the geometry of the column can be easily adjusted by steps of each 5cm.
Thanks to the formwork facing in steel, an optimal concrete surface without any marks of fixing elements is guaranteed. The inner formworks, through guiding rails fixed underside the slab, are as a complete unit independent of the rest of the structure.
The admissible concrete pressure is defined in accordance to the specifications of the project. Slim structures with maximum ecofrados. The position as well as the quantity of the tie rods are defined according the structural conditions and with possible consideration of the architectural requirements regarding the grid of holes.
The available universal panels and column panels, which usually are taken in situations of wall ylma or perpendicular wall joints, also offer a solution for columns without passing tie rods. Independently of the method of construction as cut and cover or necofrados, always the same standardized components are used. Thanks to the non-visible fixing of the plywood, a concrete surface without any marks of these fixings is guaranteed.
The possible fixing of the formwork facing birch plywood 21mm, solid wood strips from rear side does not only build the base for a possible fair-faced concrete surface, but guarantees also a more efficient working-flow during preassembly. On request the single units may be delivered preassembled. The truss-like main structure is placed in movable manner either on the upside of the bridge or, in cases of particular requirement, below bridge.
All the single components are combined with encofradso standard bolt and pin connections.

The safe access can be guaranteed by the ebcofrados ULMA ladder system. Thanks to the ease of assembly of the two steel semi-shells, columns with diameters of 0,80m can be realized; special dimensions and especially bigger diameters as well as customized shapes as required frequently for bridge piers can be supplied on request.
The flexible carriage, which is always perfectly customized to the shape and the conditions of each specific project. The modular and standard carriage, perfectly adaptable to any particular project requirement. Spindles, a hydraulic system for lifting, lowering encofrado adjusting, wheels and rollers for moving and further useful components complete the system. In the case of extremely short pier-heads the two separate carriages, subsequently provided for balanced working, can be united to one structure without need of additional components.
In cases of regular bridge section this leads to typical applications for ulka of 12m up to 18m. Other general accessories, such as props for example, are taken of the standard product range.
Rectangular as well as polycentric shapes can be realized without any problem. The formwork of complete units umla variable rectangular columns. The complete structure is moved in lengthwise sense with rollers on the rails fixed on the upside of the bridge. The provided working platform as well as the universal ULMA ladder-system, all in complete accordance to the valid safety standards, complete the system.
