A computerized method for measuring a production pallet for precast concrete component parts for the construction industry and/or at least one component, preferably at least one precast concrete component part, preferably wall element, ceiling element and/or double wall element, arranged on the production pallet. The method includes: moving the production pallet relative to at least one measuring device, preferably via a gantry or a cantilever arm, to scan the production pallet, creating at least one depth image in a direction orthogonal to the production pallet by the at least one measuring device, and determining a production pallet height and/or a production height of at least one component arranged on the production pallet orthogonal to the production pallet by a computing unit via the at least one depth image in at least two positions of the production pallet spaced apart from each other.

A composite structural building panel has a first concrete layer and a second concrete layer in spaced apart relationship with one another so as to receive an insulation layer spanning between the first concrete layer and the second concrete layer. A plurality of shear connectors are individually supported to extend through respective bores in the insulation layer between opposing first and second ends of the shear connector which are entirely embedded in the first and second concrete layers respectively. At least some of the shear connectors are oriented at an inclination to a normal axis of the insulating layer.

A plant for producing a concrete prefabricated component includes a plurality of stations, a transport system to transport the production pallet through the plant, and a 3D printing station having a layer depositing device for depositing a particulate aggregate on the production pallet and having a printing head for controlled delivery of a water-binder mixture. The plant also includes a storage device to store particulate aggregate, a conveying device to convey the particulate aggregate to the layer depositing device of the 3D printing station, a mixing device for mixing the water-binder mixture, a feed device to feed the water-binder mixture to the printing head, and an unpacking station in which a concrete prefabricated component printed in the 3D printing station on the production pallet can be unpacked from an unbound particulate aggregate.

Improved tilt-up and precast construction panels and improved methods for creating the same address deficiencies in the current tilt-up and precast construction panels. Improved tilt-up and precast construction panels use less concrete and less steel reinforcement and weigh less than current tilt-up and precast construction panels. Additionally, improved tilt-up and precast construction panels have greater insulative properties (both heat and sound) than do current tilt-up and precast construction panels. Improved tilt-up and precast construction panels require less labor on the construction site, thereby increasing efficiency and profitability of construction crews. Additional advantages of implementations of the invention will become apparent through the following description and by practice of implementations of the invention.

A wall assembly for a building structure, uses (i) an inner shell cast in a first mold to define a first panel of concrete having a plurality of stiffener members embedded in the concrete so as to be at least partly exposed at the inner side of the panel, and (ii) an outer shell cast in a second mold to define a second panel of concrete having a plurality of stiffener members embedded in the concrete so as to be at least partly exposed at the inner side of the panel. The inner shell and the outer shell are mechanically coupled after casting to define a mold cavity between the inner sides of the panels. Field concrete can be cast into the mold cavity between the inner and outer shells once the wall assembly is mounted on site into position within the building structure.
