Movable floor

The movable floor allows the use of one swimming pool for several activities: competitions, baby swim, aqua dance, disabled/remedial activity, swimming instruction, diving, activities that require different levels of water depth.

The extreme functional capacity of this floor consists in the fact that the mechanism thanks to which it moves, unlike the one of other movable floors, is placed along the walls and not on the floor of the pool, that can therefore be easily cleaned in every point, also with automatic cleaners.

The movable floor is furthermore provided with all the safety elements required from the international regulations: in fact it is closed frontally by a floor connection flap, or by a bulkhead, that have the purpose to stay fixed against the floor when this is lifted.

The Floor structure

The movable floor is formed by floating frame of stainless steel pipes and composite resine beams. The heads of the steel beams are connected to two screw jacks that allow the movement of the floor up and down. The strusture is then covered by 90 mm wide anti-slip PVC boards, co-extruded with closed-cell foam.

The movement

The floor is anchored to the screw jacks (endless screws) recessed into the Myrtha walls. Two screw jacks are required at each stainless steel beam end. The anchoring is very simple. The screw jacks are moved by an electric motor. One 4 kW motor provides the rotation to the screw jacks on one side of the pool. Another motor, synchronised with the first, provides the movement to the screw jacks at the other side of the pool. With just two 4 kW motors it is possible to move a 200 m2 floor. No anchoring or cable is necessary under the floor. The floor moves at a speed of 20 cm/min.

The connection with the pool floor

A bulkhead can be positioned against the movable floor, providing a safety wall. Alternatively a flap may be provided which is self-levelling according to the movable floor position.

Installation detail

Water inlets are installed inside the recessed Myrtha columns which house the screw jacks, in order to circulate the water inside. The socket is protected by two Myrtha steel panels, that leave a gap that is only 8 mm wide, sufficient for the connection to the floor and suitable to guarantee its movement with the maximum safety.
The pool needs only to be 60 cm deeper in order to house the movable floor at its lowest position and maintain a flat bottom.

Removable floors for depth reductions

An easier possibility to change the depth of the pool consists in the use of a trestle structure (2x1 m) resting on the floor and easily removable after the period of utilization.

It is a set of structures made of an ABS grating on the upper shelf and of a stainless steel trestle, that are hitched together to cover the whole surface of the pool floor.

This system is the ideal solution for all those swimming structures that need to change the depth of the pool only periodically, or for some months of the year. In fact, besides being very simple and fast to be installed in the pool, it does not require any intervention on the pool walls and its costs are no doubt less considerable than those of the movable floor.
