In one aspect of a reinforced tile, the reinforced tile may be configured for use with a support structure that may be engaged with a top portion of a pedestal. The reinforced tile may be configured with a substrate adhered to a back side of a tile, and the substrate may be comprised of a fiberglass material. A groove may be formed along at least one edge of the reinforced tile, and the groove may be positioned at the interface of the tile and substrate. The support structure may be formed with a generally vertical spine having at least one rail extending outward from a distal end thereof. The spine and rail(s) may be configured to secure one or more reinforced tiles, wherein one or more rails may be positioned within a groove formed in the reinforced tile.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.

The support structure may be formed with a generally vertical spine having at least one rail extending outward from a distal end thereof. The spine and rail(s) may be configured to secure one or more tiles, which tiles may be formed with a groove on at least one edge thereof, and wherein one or more rails may be positioned within the groove.

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.

A shelter includes a floor portion, at least one wall portion having a top wail portion, a bottom wall portion, or both, and a roof portion. Each portion includes at least two panels which are detachably interconnected using female and male bracket elements configured for receiving the panels and including cooperating means actuated by longitudinal movement for preventing separation of the female and male bracket elements and interconnecting the panels.

An assembled slab-type steel-wood composite joint, includes a steel-wood composite column, square wood beams, connecting assemblies for connecting the steel-wood composite column and the square wood beams, and wood slabs connected to and supported by the steel-wood composite column, the square wood beams and the connecting assemblies. The steel-wood composite column includes a hollow cross-shaped outer square wood column, and square blocks are integrally formed on the outer square wood column; and a steel sleeve is inlaid in the outer square wood column, an inner wood column is inlaid in the steel sleeve, column vertical steel bars penetrate through the inner wood column, horizontal steel bars penetrate through the square blocks and are fixedly connected to the steel sleeve, and threads are arranged at the ends of the horizontal steel bars.

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.
