The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

An arena apparatus for staging a sport is provided. The apparatus includes a floor having a perimeter; and at least one wall coupled to the floor at the perimeter and extending upwardly and outwardly from the floor at an angle relative to an axis perpendicular to the floor, wherein the angle of the wall prevents an athlete from standing on the wall.

A nut to be used as part of a fastener to be used in multiple ways in various industries or methods has a drive mechanism and stud extending from the drive mechanism with a threaded bore. In addition the nut can be specifically used as a method and as part of special fastener that can be used to join cut, hard-wood members, other naturally occurring manufactured mat members or synthetically man made members, referred to as “timber(s)” or “laminated”, in forming a mat used for heavy construction equipment to run on over ground which is not stable. These mats are commonly referred to as “Crane Mats” or “Laminated Mats” in the construction, mining, pipeline, and oil and gas industries among others.

A structural reinforced composite construction mat includes a plurality of composite plastic beams that are ganged together to define the mat, with a plurality of flitch plates disposed between at least some of the plastic beams to provide additional strength and rigidity to the mat. The plastic beams may be made of a composite material have a generally rectangular cross-section. The flitch plates have a width (vertical height) when disposed between adjacent beams that is less than the width (vertical height) of the beams, such that the flitch plates may be recessed below and above the top and bottom surfaces of the mat, respectively. A plurality of rods extend in the lateral direction through the beams and plates to compress the beams and plates against each. The flitch plates may be metal or fiber-reinforced resin and may further include slotted holes to allow the beams to retract lengthwise in response to environmental changes.

Disclosed is a modular building system including, in some embodiments, one or more wall panels, one or more floor panels, and one or more roof panels. The modular building components of the modular building system including the one or more wall panels, the one or more floor panels, and the one or more roof panels can faun housing or storage structures with electrical wiring, plumbing, or both wiring and plumbing. The housing or storage structures can be erected by one or more persons without a need for a plumber, an electrician, or power tools. Also disclosed is a method for erecting one or more housing or storage structure in accordance with the modular building system.

A gait assistance slab is provided. The gait assistance slab includes a body that includes an outer surface. The gait assistance slab further includes a plurality of sensors disposed inside the body. The gait assistance slab further includes a plurality of actuators disposed inside the body. The gait assistance slab further includes circuitry communicatively coupled to the plurality of sensors and the plurality of actuators. The circuitry detects a presence of a person on the outer surface based on an electric signal acquired from one of the plurality of sensors. The circuitry determines a level of actuation of one of the plurality of actuators based on the detected presence of the person and the acquired electric signal. The circuitry further controls, based on the determined level of actuation, the one of the plurality of actuators to assist gait of the person on the outer surface.

The invention proposes a system for constructing a module of a building, including core construction elements (1) that are surrounded by the surrounding construction elements (2A, 2B). The core construction elements (1) each include, in section, a cross including two main arms (6) of equal length which intersect at mid-length at right angle. Each core construction element (1) has a plane of symmetry about the axes of the arms. The main arms (6) of the cross terminate, at the ends thereof, with transverse portions (7). Each surrounding construction element (2A, 2B) is composed of four partial surrounding parts (2A, 2B, 2A′, 2B′) of a generally triangular shape which are assembled around a core element (1). Construction elements forming junction parts (4A, 4B) allow assembling panels (4A, 4B) to form a module of a building in the form of a rectangular parallelepiped volume comprising four corners.

A lightweight universal panel mat made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the mat and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The panel mats have first, second, third and fourth sides that are configured to matingly engage or connect to the second, third, fourth and first sides, respectively. The connection can be by insertion or snap-locking of one side to another, or by the use of fastening elements that more securely holds the sides together. Thus, similarly configured panel mats can be connected by interlocking to form a temporary support surface, deck, walkway or roadway. Additional side ramps and adapters can be used to facilitate installation of the mats and access to the upper surfaces of the joined mats.

A modular constructed building includes a plurality of ground beams and a plurality of wall panels, each ground beam has a pair of surfaces and a longitudinally extending male projection interspaced between the pair of surfaces. The extending male projection is formed as a flat plate and at least able to be partially inserted into a wall panel with each of the wall panels being secured to a respective ground beam, so that each wall panel, at an end opposite the ground beam, has a lateral groove for accepting a protrusion for a T-shaped member or an X-shaped member, and an upper end of each of the wall panels is retained together through each of the wall panels and either a T-shaped member or an X-shaped member.
