A haptic floor system is provided that produces large vibration-based effects through the use of one-to-many panel or plate assemblies that can each be selectively operated by a controller in a programmed manner or in response to sensor outputs. Each of these panel or plate assemblies may be labeled a quake plate assembly as the special effect delivered by the haptic floor system can provide a person supported by one of the quake plate assemblies with ground trembling and vibrations similar to that felt in an earthquake or when a super strong fictional character strikes the floor nearby or a large animal or robot walks or runs by the person. Each quake plate assembly may include a thin plate or panel with an upper contact surface for supporting people or objects and an opposite lower surface, and one-to-many actuators may be provided on the lower surface of the thin plate.

Disclosed herewith a prefabricated frame, including a column (1), a main beam (2), a secondary beam (3), and a floor (5). The main beam (2) and the secondary beam (3) are both prefabricated members, and provided with exposed reserve reinforcing bars. The floor (5) is a laminated plate having a prefabricated slab (51) at a lower portion thereof. The prefabricated slab (51), the main beam (2), and the secondary beam (3) are connected together through in-situ casting concrete on respective top portions thereof. The column (1) is a prefabricated column, which has exposed reserve reinforcing bars at a top thereof, and a to-be-cast structure at a bottom thereof for connection with a lower building structure, which has exposed reinforcing bars inserted into the to-be-cast structure. The connection between the column (1) and the lower building structure is achieved by casting in-situ concrete in the to-be-cast structure (12).

The present invention is a modular structural building method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

In one aspect, a reinforcing assembly includes one or more longitudinally-extending bars having a first end, a second end opposite the first end, and a midpoint between the first and second ends. The reinforcing assembly also includes multiple downwardly-extending working members each independently connected to at least one of the one or more bars. The working members are oriented diagonally with respect to a longitudinal axis extending along the one or more bars. The working members connected to the one or more bars between the first end and the midpoint are angled in a different direction than the working members connected to the one or more bars between the second end and the midpoint.

A system for preventing cracks in a concrete floor associated with a building structure, the building structure having a plurality of support columns for supporting the building structure, is provided. Each support column has a base with at least three sides and is embedded in a ground surface underneath the building structure. The system also includes one or more crack prevention members having a first surface and a second surface, an outer side wall and an inner side wall defining a cut-out portion. The crack prevention member may comprise various materials including rubber, plastic, resin, or other polymeric material and combinations thereof.

A panel assembly for a building includes a panel configured to extend between a first surface and a second surface. The panel is movable along a predetermined path relative to the first surface and the second surface. A first pin and a second pin are coupled to the panel. A first bottom face plate is positioned on a first side and defines a first slot. A second bottom face plate is positioned on a second side and defines a second slot. A first top face plate is positioned on the first side and defines a third slot. A second top face plate is positioned on the second side and defines a fourth slot. The first pin is movable in the first slot and the second slot, and the second pin is movable in the third slot and the fourth slot for guiding movement of the panel along the predetermined path.

A shearwall assembly includes a first concrete and a second concrete column and a protrusion extending from a connection end of the respective concrete columns. Each protrusion has two side surfaces and a center surface. A pair of horizontal slab panels are positioned between the respective connecting ends of the first and second concrete columns and abutting the two side surfaces of the respective protrusions. A horizontal reinforcement extends from the center surface of the respective protrusions and between the respective trusses. Concrete is poured at a volume formed between the pair of horizontal slab panels and the first and second concrete columns.
