An erection anchor is provided having a head and first and second legs affixed to opposite sides of the head, whereby the first and second legs each have a threaded lower section extending downward, away from the head. The erection anchor may be embedded in a precast concrete panel, such as a multilayer panel having an insulation core layer sandwiched between concrete layers. The erection anchor may be embedded in the multilayer panel with the head exposed and the first and second legs each embedded in a concrete layer on opposite sides of the insulation layer.

Systems, methods, and an apparatus are provided for supporting a wall panel on a floor surface and for providing a desired distribution of a load from the wall panel to the floor surface. For some buildings, the desired distribution is an equal or uniform distribution. A wall panel such as a precast concrete façade wall panel may include multiple supports that contact a floor surface. Each support has a bias member that generates a force that is equivalent to the portion of the overall load that the support transfers to a floor. As a result, bias members in these supports can be adjusted to provide a desired load distribution from a wall panel or other component to the floor surface to account for floor deflection, settling of the building, spanning adjacent columns, etc.

Systems and methods for a concrete apparatus with incorporated lifter are provided. A concrete apparatus is formed by placing a reinforcement system in a mold. The reinforcement system comprises a lifter. Concrete is poured into the mold such that the lifter protrudes from the poured concrete. After the concrete has hardened and the mold is removed, the lifter is used to carry and position the concrete apparatus. After the concrete apparatus is positioned, the lifter is removed at the circumference of the concrete apparatus leaving no holes, thereby eliminating water leakage due to lifting methods.

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.

A structural panel is manufactured from at least two generally parallel and spaced-apart thin-shell cementitious skins that are joined by a truss matrix. The elements creating the truss matrix, being the truss, the face mesh, and the insulating core, are selected to meet the structural loads to be placed thereon. The thickness of each cementitious skin is selected to meet the structural loads to be placed thereon.

The method for pouring concrete around a window frame begins by spraying a flat surface with a release, followed by positioning window assemblies on the flat surface. The window assemblies include at least a frame, and also possibly a sash, glazing and removable bracing. The window assemblies are secured to the flat surface and then concrete is poured around the window assembly to form a wall. Once the concrete cures around the frame, the bracing is removed, and the wall is tilted/lifted to a vertical position.

A voided floor panel is provided. The voided floor panel includes a pre-cast dome, strands, reinforcing bars, and a slab. The pre-cast dome includes a flange portion, stem portions, and joint portions. The strands are pre-tensioned. The reinforcing bars are inserted through rebar block-outs of the pre-cast dome. The joint portions, the strands, and the reinforcing bars are cast within the slab. The strands improve a resistance of the slab to flexure. The joint portions improve a vertical shear resistance between the slab and the pre-cast dome. The joint portions may include corrugated dovetails for further improving a horizontal shear resistance between the slab and the pre-cast dome.

A method of forming an architectural concrete structure having a desired look (i.e., color) and texture, wherein the method generally includes pouring a base concrete layer using conventional concrete. A surface concrete mixture is prepared and includes a mixture of sand and small aggregates to give the surface concrete mixture the desired color and texture for the architectural concrete structure. The base concrete layer provides strength and durability to the concrete structure, while the surface concrete layer provides the desired look and texture of the concrete surface. The surface concrete mixture preferably includes small aggregates to create a smooth and uniform texture.

A board consisting at least of a substrate formed at least of a gypsum-based and/or cement-based basic material layer. The board is provided with a chamfer extending through the basic material layer.

A ventilated wall module (10) of the type used in civil construction for a range of buildings using pre-fabricated components, such as one-story homes, large houses, houses, schools, hospitals, industrial sheds, inter alia; the wall module (10) includes a pair of panels (20A) and (30A) that are produced independently of one another by automated, robotic equipment (E1), based on large moving metal surfaces (M1) that slide on rails (T1); said mechanized method (M1) developed for the production of the panels (20A) and (30A) includes an industrialized construction system (SC) for producing each wall module (10) comprising the combination of the coordination and compatibilization of the designs to be implemented with the pre-installation of the complementary components such as electrical boxes (c1) or other necessary elements.
