A prefabricated concrete pool including concrete walls and a pan-formed concrete floor, as well as a method of fabricating a prefabricated swimming pool, the method including erecting an external wall form, erecting an internal wall form opposing the external wall form, and positioning pan forms on a floor form.

Speed reduction gear comprising two intermediate transmission lines, in particular for a turbine engine, comprising an input line (12) and an output line that is driven by the input line via said intermediate transmission lines, said intermediate transmission lines being substantially parallel, characterised in that said reduction gear comprises means for distributing loads between said intermediate lines, said load distribution means comprising swiveling coupling means (30) for rotatably coupling one end of the input line, and oil-damping means (40, 50) for damping radial movements of an opposite end of the input line.

The invention is an assembly of prefabricated metal receptacles forming a swimming pool and a method for constructing the assembly. Among other features, the assembly is characterized by guided clamping structures that allow on-site construction without requiring on-site welding or access to the bottom or interior of the assembly.

A Exercise Pool is disclosed herein having a rigid frame modular in design to allow for improved delivery and assembling. As shown the system may be configured with a box like structure providing containment of the flow head and may be configured with a removable deck having an air gap built in. As disclosed the treadmill swimming pool system as its general configuration is safer for users as it inhibits and/or eliminates hair and body entrapment. As disclosed it has a balanced flow which better replicates or reproduces actual swimming conditions for an enhanced user experience. The propulsion system may be controlled with a variable frequency drive (VFD) to allow for improved swimming conditions and control of same.

A modular swimming pool with one or more swimming pool modules that each include a floor element, and a wall element connected to the floor element. The swimming pool modules by assembly define an internal pool space. The floor element and the wall element of a swimming pool module have reinforcement ribs and the reinforcement ribs of the wall element extend towards the floor element. The reinforcement ribs are spaced apart from each other and on the external surface form open chambers configured, when resting on a mounting surface, to be completely filled with a binder. The internal pool space in the area of the floor element has a wedge-like recess, forming a continuous duct area of the internal pool space, and the reinforcement ribs of the floor element are connected to an external surface of the recess, which faces away from the duct area, thereby restricting the open chambers.

A pump unit for a prefabricated swimming pool, the unit having a pump wall panel and a mount connected to or integral with the pump wall panel. There is also a pump located or locatable at the mount. The arrangement is such that when the pump unit is in use the pump is able to drive a current of water through the pump wall panel into a pool sufficient to enable on the spot swimming inside the pool.

A pool is provided, including an enclosure body, a sealing plate, and a plurality of shaping plates, wherein the enclosure body is of an annular structure with two open ends, the enclosure body is provided with a plurality of receiving cavities in a circumferential direction thereof, and the plurality of shaping plates are respectively arranged in the plurality of receiving cavities in one-to-one correspondence; the enclosure body is connected to the sealing plate, and the sealing plate seals one of the two ends of the enclosure body, so that the enclosure body and the sealing plate define a water storage cavity together.

Systems and methods for modular walled systems, such as modular walled spas and modular walled privacy fences and can protect pool and spa equipment from the public. In one embodiment, the modular walled system includes an outer frame disposed within a medial frame, and an inner frame disposed within the medial frame, wherein each frame includes a set of brace assemblies that connect to rebar grids. The brace assemblies may include a foot plate and threaded couplers. The wall system also provides protective room for electrical raceways and a secure anchor substrate to attach electronics, panels, boxes or lighting systems.

Modular pool comprising a support structure placed around a containment basin for the water and comprises a plurality of metal plates, joined together, which comprise a base for resting on the ground, an upright at least partially above ground, and lateral edges provided with a reinforcement flange. The pool also comprises fixing elements fixed to the base of the metal plates and anchored to the ground, a waterproofing layer placed to coat a bottom and a lateral surface of the containment basin, and a surface finish layer placed to cover the waterproofing layer.

An apparatus and system for assisting in assembling, aligning, and leveling the wall panels of an inground swimming pool, the apparatus comprising an adjustment member having an externally threaded shaft section, an internally threaded fastener which is rigidly attached in a hole in a bottom flange of a wall panel, and a cleat member which is adjustably connected under the bottom flange such that the wall panel can be supported on the cleat member, whereby the wall panel can be raised or lowered as needed during assembly, alignment, and leveling of the pool wall by rotatably adjusting the position of the adjustment member, whereby the tensile strength of the threaded shaft is less than that of the threaded aperture in the cleat member such that an area of the threads on the threaded shaft section spaced from the end of the shaft section are intentionally fractured or damaged, preventing prevent the cleat member becoming disengaged from the panel.
