A swimming pool wall, and method for forming same, including a plurality of layers of reinforced composite material. Each layer includes a thermoplastic resin and a plurality of elongate glass strands of reinforcing material. A first set of the plurality of layers has the strands miming in a first direction, and a second set of the plurality of layers has the strands miming in a second direction. The first direction is offset in angle from the second direction, and the first and second set of layers are fused together to form a unitary composite wall. The principles of hoop strength applicable to the swimming pool wall also apply to other cylindrical structures needing hoop strength arising from pressures inside or outside the cylindrical structure. The wall structure may be a plurality of interconnected panels both arcuate and arcuate and planar in shape to determine the overall shape of the composite wall enclosing an area where water or ice is retained.

A prefabricated self-supporting module for making building structures, more particularly swimming pools, is provided. The module comprises a matrix made of foamed material and a supporting structure made of metal coupled to the matrix. The supporting structure made of metal may be embedded in the matrix made of foamed material (internal supporting structure) and/or cover the matrix made of foamed material (external supporting structure). Thanks to the provision of the supporting structure made of metal, the module is self-supporting, and it does not need any further reinforcements of reinforced concrete. Thanks to the provision of the supporting structure made of metal, the module can be used for making structural supporting elements such as floors, side walls, and so on. This module can be completely made and finished in the factory, so that the steps to be carried out on the construction site are extremely limited, with consequent economic saving.

An above-ground modular pool which is unsupported by an embankment has a plurality of interconnected and inflatable water-exposed units entirely made of reinforced composite polymeric material, and a plurality of floor panels each of which is connected to one or more of the water-exposed units, such that each of the plurality of water-exposed units is of sufficient structural strength to withstand the hydraulic pressure applied thereto by a body of water received in the pool.

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.

A non-inflatable above-ground pool is provided, including: a pool bottom and a pool wall connected to an edge of the pool bottom, together defining a water storage cavity. The pool wall comprises an inner wall, an outer wall, and a top sheet. Each of the inner wall and the outer wall have an upper edge connected to the top sheet and a lower edge connected to the pool bottom so as to define a filling chamber. A support wall body is disposed in the filling chamber and includes a wall body opening therethrough. A control box is arranged in the wall body opening and is in fluid communication with the water storage cavity via the inner wall.

A non-inflatable above-ground pool is provided including a pool bottom and a pool wall connected to an edge of the pool bottom to thereby enclose a water storage cavity. The pool bottom includes interconnected upper bottom sheet and lower bottom sheets. The pool wall includes an inner and outer wall and a top sheet. Each of the inner wall and outer walls have an upper edge connected to the top sheet and a lower edge connected to the pool bottom, defining a filling chamber. Alternatively, inner and outer walls and top sheets are connected to an upper edge of each of the inner wall and the outer wall, thereby enclosing a filling chamber. A lower edge of the inner wall may be connected to the lower bottom sheet. A support wall body is disposed within the filling chamber, and in an embodiment, includes a wall body opening therethrough.

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.

An above-ground pool insulation assembly and method of insulating an above-ground pool provides at least one modular panel fabricated from perimeter and reinforcement steel bar that form a rectangular frame. The frame is encapsulated by a metallic sheet to create a pocket of insulating air. An adhesive metallic tape secures the metallic sheet to the frame. Resilient strips attach to the edges of the cover panel to help prevent moisture from entering the mount side. The modular panel mounts mechanically and magnetically to the peripheral sidewall of an above-ground, metal sided swimming pool, so as to insulate the pool, and thereby reduce heat loss from the body of water in the pool due to efficiency of conservation of energy exchange with the environment.

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, characterized 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.

An above-ground pool wall assembly apparatus is disclosed which allows the single handed mounting of the pool wall along the pool wall bottom rail. The rolled up pool wall is mounted on a turntable and kept upright by a plurality of retainer posts. As the wall is unreeled a series of guide posts help separate the unreeled portion of the wall from the roll and guide the wall into position on the bottom rail. As the pool wall is progressively mounted along the bottom rail, the apparatus can be kept in the proper position by wheeling the apparatus around the bottom rail in coordination with the progress of the installation.
