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 modular perimeter frame system is described for forming a perimeter frame used in the construction of floors, walls and roofs of buildings. The modular perimeter frame system has a first modular sub-frame having one or two blunt end portions, and a second modular sub-frame having one or two overhang end portions. The blunt and overhang end portions are so dimensioned and shaped as to facilitate a continuous abutting engagement between at least two surfaces which meet at a corner of the blunt end portion and at least two surfaces which meet at a corner of the overhang end portion.

A floor frame includes at least two spaced longitudinal support strips and at least one lateral support strip. Each longitudinal support strip has longitudinal upper and lower portions and a pair of longitudinal side walls. A shoulder is designed on at least one of the pair longitudinal side walls and located between the longitudinal upper and lower portions. Two shoulders of the two longitudinal support strips are opposite to each other. The lateral support strip includes lateral upper and lower portions and a pair of lateral side walls. Two ends of the lateral support strip are placed on the two shoulders of the longitudinal support strips, respectively. A plurality of longitudinal and lateral support strips constitutes a grid-type structure under the distribution of longitudinal and lateral directions to provide the placement and fixation of a plurality of floor panels.

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.

Fabrication of a multi-story building includes fabricating floor plates at or near ground level, and lifting them to a final position on a vertical support core. A method for assembling one of the floor plates assembling a floor plate frame near ground level. Cambers are imparted into framing members based upon expected deflections, and metal decking is installed onto the floor plate frame. A plurality of permanent support points for the floor plate are determined, wherein the floor plate is attachable to the vertical support core at the permanent support points. First pedestals are installed between ground level and the floor plate frame proximal to the permanent support points for the floor plate. Hardenable material is dispersed onto the metal decking of the floor plate frame while the floor plate frame is lifted at the permanent support points.

A modular system for the dry building of structures for constructions, such as walls, floors, balconies, roofs or the like, includes a plurality of planar modular beams that define a respective plane and that are mutually jointed, and a plurality of planar panels anchored thereto at least at or in proximity of the end portions of the same planar modular beams.

A new design and rapid construction method for flush assembly of prefabricated steel beams and floor slabs is disclosed. The upper flange of prefabricated steel beams is “” shaped, which consists of horizontal flange, vertical flange and top flange. Both beam stiffeners and studs are set on the horizontal flange, in which the former can strengthen the bearing capacity of the beam and avoid its local deformation, and the latter can fix the floor slab; prefabricated studs and precast concrete inside the vertical flange in the factory are used to constrain the deformation of upper flange. There is no limitation with respect to the form of floor slab, which is connected with the prefabricated steel beam by hitching the prefabricated rebar ring of the floor slab to the welded studs of the upper flange of the prefabricated steel beam.
