Modular building methods and systems using lightweight modular panels, and specially configured transition panels for transitioning from wall to floor, or from wall to roof. Identically configured standard panels are used for constructing the walls, floor, and roof, with transitions from one structure to the next (e.g., wall to floor, or wall to roof). Each of the variously configured panel types includes channels (e.g., 2 pair of channels) formed through the length of the foam body, where the channels are configured to receive splines (e.g., flanges of an I-beam) therein. In the standard panel, the channels may include pairs of top and bottom channels, with the channels offset towards the respective panel major faces. In the transition panels, the channels may be similarly configured, but positioned differently to make the appropriate transition. The splines are connected to a frame, which acts as a template and transfers loads to a foundation.

A deck apparatus for assembly with a pair of opposing brace frames interconnected by a pair opposing connector bases and a deck board top frame having a plurality of deck boards disposed thereon, the connector bases having opposing posts for being received in openings in a lower end of the opposing brace frames ends and the deck board top frame having posts for being received in an upper end of the opposing brace frames, and optionally attaching a stairs riser having a plurality of spaced-apart treads or a ramp riser for extending from a deck surface at a height to a vertically lower support surface.

Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

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 elevated flooring system is operable to support a flooring panel. The elevated flooring system includes a beam configured to support the flooring panel. Aspects of the flooring system also include a saddle with a base surface and a prong. The beam is engaged with and vertically supported by the base surface of the saddle. The beam is configured to support the flooring panel and defines an aperture configured to receive the prong. Aspects of the beam includes a tent attachment assembly and a beam wall defining an aperture and opposite wall surfaces. The tent attachment assembly is configured for attachment to the tent and includes a base, a boss plate, and a threaded fastener. The fastener extends at least partly through the apertures of the base, boss plate and beam wall and is threaded into the boss plate.

A Cross-Laminated Timber (CLT) connection is provided that can be used to connect at least two CLT components such as CLT panels. The CLT joint includes a first CLT component, a second CLT component, and a spline. The first CLT component includes a first recessed channel. The second CLT component includes a second recessed channel. A first end of the spline is configured to nest within the first recessed channel. A second end of the spline is configured to nest within the second recessed channel. The CLT panel includes a first CLT side and a second CLT side. The first CLT side includes a recessed channel. The second CLT side may be opposite the first CLT side and includes a grooved extension. The grooved extension and the recessed channel have complimentary patterns. A CLT panel system is also provided comprising a plurality of CLT panels.

An integrally assembled hidden beam hollow two-way floor system includes precast slabs (1), honeycomb steel beams (3), and cast-in-place concrete (4). A plurality of compartments (12) arranged in a matrix is integrally provided on one surface of each of the precast slabs (1), and connecting grooves (14) are provided at a periphery of another surface of the precast slab (1) is provided with connecting grooves (14). Prepared bolt holes (13) penetrating through the precast slab (1) are provided in the connecting grooves (14). The honeycomb steel beam (3) serves as a primary beam or a secondary beam of a steel structure of the floor system. A surface of the precast slab (1) provided with no compartments is lapped and fixed between the secondary beams or between the primary beam and the secondary beam, and adjacent precast slabs (1) are connected and fixed by a U-shaped hoop (2) passing through the prepared bolt hole (13) to form a seam. The cast-in-place concrete (4) includes a surface layer cast onto the compartments (12) and a cast-in-place concrete ribs (41) cast between the compartments (12) of adjacent precast slabs (1) and between the compartment (12) and the primary beam and the secondary beam, the surface layer and the cast-in-place concrete ribs (41) being integrated. An assembly method for the integrally assembled hidden beam hollow two-way floor system is further provided. A method for assembling an integrally assembled hidden beam hollow two-way floor system is provided. The floor system and method for assembling the same achieve similar force performances in two directions, reliable connection between the floor slab and peripheral members, elimination of a risk of cracking of slab seams, and improved assembly efficiency.

The present disclosure relates to a field of construction engineering, and in particular to a reinforcing structure of a concrete overhead layer before a building expires. The reinforcing structure of the concrete overhead layer includes supporting structures, connecting structures, and metal members; wherein the reinforcing structure is configured to reinforce a concrete floor slab and/or a concrete beam; through holes are disposed on the concrete floor slab; each of the supporting structures passes through each of the through holes and the supporting structures are configured to support the concrete floor slab and/or the concrete beam; and each of the connecting structures is configured to fix each of the supporting structures on each of the metal members; each of the metal members is disposed on each of the through holes.

An elevated flooring system is operable to support a flooring panel. The elevated flooring system includes a beam configured to support the flooring panel. Aspects of the flooring system also include a saddle with a base surface and a prong. The beam is engaged with and vertically supported by the base surface of the saddle. The beam is configured to support the flooring panel and defines an aperture configured to receive the prong. Aspects of the beam includes a tent attachment assembly and a beam wall defining an aperture and opposite wall surfaces. The tent attachment assembly is configured for attachment to the tent and includes a base, a boss plate, and a threaded fastener. The fastener extends at least partly through the apertures of the base, boss plate and beam wall and is threaded into the boss plate.

Precast Building Construction System A building construction system uses precast concrete panels (10) interconnected in an array to provide both floor and ceiling of a multi-unit building. Each panel has a reinforced precast concrete slab having an upper surface (12) and downstands (18, 20) providing a continuous enclosure beneath the floor surface. Grooved voids (44, 58) are preformed into the upper and lower surface of the downstands for receiving connectors (54, 56, 57 or 60, 62, 66 and 50, 52) for connecting adjacent panels. Preformed recesses (19) are provided at the edges of the panel for connecting the panels together and creating grouted shear keys (59).
