A building block for construction of a building includes a floor and walls. One of the walls includes a recess box. The walls are fixed to the floor and to one another. The floor includes a support made from wood-concrete and defines grooves. A metal armature formed by a plurality of metal rods is arranged in the grooves. At least first metal rods are salient from the ends of the first grooves. A concrete fills the grooves and completely covers the metal armature and the support. The walls are made from wood-concrete and define a vertical groove on their external surface extending over the height of the walls and opening onto the first metal rods salient from the support.

A system for wall to wall connection for precast shear walls includes a plurality of horizontal and vertical reinforcement bars configured within the precast shear wall. The system also includes a plurality of connecting tubes fixed between the spacing provided between the reinforcement bars, a plurality of openings provided between the plurality of connecting tubes, a plurality of grout tubes fixed above the plurality of openings to grout the openings after completing confection of the shear walls, a plurality of connecting bars capable of being inserted within the connecting tubes of the precast shear wall, when erected, a connecting device for inserting through the openings to grip the connecting bars, and a driving device to supply power to the drive for causing rotation of the drive/manual action and, thereby, sending the connecting bar in a translational motion from the first shear wall to the second shear wall.

An outer wall of a building has a frame and a coating layer. The frame has multiple surfaces. The coating layer is coated on at least one of the surfaces of the frame and is composed of a glass-fiber net and an adhesive material layer. The adhesive material layer is composed of acrylic resin, Hydroxyethyl Cellulose (HEC), and water.

A rebar coupler can have a coupler body with a hollow interior, and a first end and a second end that are open to the hollow interior to receive rebar into opposing ends of the hollow interior along a longitudinal axis. One or more grout ports can be included on the coupler body, including a first grout port on the first end of the coupler body. The coupler body can include a set screw, a removable stop, a narrowed first end, a removable cap, or other features.

A connecting system for connecting concrete beams of a parking structure including a pair of concrete beams and a plurality of spring-like connectors connected between the pair of concrete beams. The concrete beams are each provided with an aperture and the spring-like connector is in a form of a pre-formed carbon fiber bundle or metal and has opposite ends that are secured in the apertures in the concrete beams by an adhesive.

A plurality of panel subassemblies are used to erect a building on a footing or foundation. Each panel subassembly includes at least one column formed of a thermally-insulating material, and a concrete portion at least partially attached to the at least one column. The concrete portion may be formed as a single precast unit. The panel subassemblies are secured together and to the foundation, and may be secured to a floor element of the building to at least partially support the floor element.

Redefining modular construction, our Modular Building System surpasses existing methods of both traditional and modular construction. Every component, meticulously crafted such that it may be robotically produced and assembled, ensures unmatched precision and efficiency. Each panel, guarantees seamless integration and flawless finishes. Fully-finished in factory settings, they drastically simplify the construction process by eliminating many traditional materials and components, while retaining ease of construction and transportability from factory to building site, for final assembly. Our system's prowess extends to design flexibility, enabling construction of expansive living spaces with ease. Furthermore, its eco-conscious design facilitates effortless deconstruction and reuse, reducing environmental impact and waste. Revolutionizing the industry, this comprehensive solution heralds a new era of construction efficiency, adaptability, and sustainability, setting the standard for future developments, and aligning the construction industry more closely with modern automotive manufacturing and aerospace production industries.

The invention relates to a method for erecting a structure 0 comprising at least two prefabricated concrete elements 1, 2, the method comprising: installing a first concrete element 1; placing a second concrete element 2 with at least one spacer 4 maintaining a gap between respective end faces 104, 203 of the first element and second element; tensioning at least one bar 105, 3 held on the first and second elements and passing through the gap maintained by the spacer, and introducing a hardenable interface product 5 into said gap. The method thus makes it possible to move off the critical path relating to the erection the need to wait, between two assembly operations, for the joints between the assembled pieces to have hardened. Incidentally, a significant reduction in the time taken for erecting such a structure is obtained.

Disclosed is an anchor having a sleeve and a concentric shaft having head at one end with a rectangular plate through with the shaft interposed between the head and the adjacent end of the sleeve. A deformable plate is positioned on the shaft between the head and the sleeve so that movement of the sleeve along the shaft towards the head deforms the plate from a configuration where the plate is substantially confined to an area within the perimeter of the head into a substantially planar configuration where the perimeter of the plate extends at least partially beyond the perimeter of the head. Also disclosed is a method of fixing the anchor in a bore hole with the ends of the plate in an undercut in the bore hole and filling the bore hole with resin while venting air via a passage extending from adjacent to a closed end of the bore hole through a suitable cover.

A plurality of panel subassemblies are used to erect a building on a footing or foundation. Each panel subassembly includes at least one column formed of a thermally-insulating material, and a concrete portion at least partially attached to the at least one column. The concrete portion may be formed as a single precast unit. The panel subassemblies are secured together and to the foundation, and may be secured to a floor element of the building to at least partially support the floor element.
