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.

An electrical system for installation in a building project includes an electrical panel assembly with a chassis and at least one housing and one or more line voltage source connection points mounted to the chassis. The system also includes one or more low voltage power sources mounted to the chassis, wherein the electrical panel assembly is located in a predetermined location in the building project for connection to one or more low voltage components via direct connections and to one or more line voltage outlets.

An elongated structural barrier is provided including a base, a first panel extending upward from the base, a first sealer wall extending downward and transversely to the base, a second panel joined with the first panel and extending upwardly, a lower wedge extending upward from the base adjacent the first sealer wall, and a core compartment bounded by the lower wedge and the panels, with an open face defined above the lower wedge and offering a view into the core compartment. The lower wedge can include a flange to produce a first cavity of the compartment, in which an intumescent core can be positioned and configured to expand into a second cavity of the compartment when it swells. A second flange can oppose the first flange to further secure the core in the first cavity, and can form a bloom gap therebetween. A related method of use also is provided.

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.

An arena apparatus for staging a sport with at least one athlete is provided. The arena apparatus includes a floor having a perimeter; and at least one wall at the perimeter and extending upwardly and outwardly from the floor at an angle greater than or equal to fifteen degrees measured from an axis perpendicular to the floor, wherein the angle of the wall prevents the athlete from standing on the wall.

An end bracket for a wall system includes a body member having attachment structure to join a horizontal strut to a vertical strut. The end bracket further includes attachment structure in which the horizontal strut is slidably attached for moving and positioning the horizontal strut relative to the vertical strut in forming the wall system.
