A method for constructing a three-dimensional (3D) printer-printable wall system includes forming a concrete foundation on a substrate, where the concrete foundation embeds horizontal and vertical reinforcements. A first inner wythe horizontal layer and a first outer wythe horizontal layer are printed using a concrete mixture from a 3D printer. The first inner wythe horizontal layer and the first outer wythe horizontal layer are separated by an interstitial space. A first wall dam is placed between the first inner wythe horizontal layer and the first outer wythe horizontal layer in the interstitial space. Additional inner wythe horizontal layers are printed on top of the first inner wythe horizontal layer to form a composite inner wythe. Additional outer wythe horizontal layers are printed on top of the first outer wythe horizontal layer to form a composite outer wythe. At least one additional wall dam is placed on every horizontal layer, while a wall tie and an attachment bracket for utility lines are placed only on pre-defined intervals of horizontal layers of the composite inner wythe and the composite outer wythe, which are separated by the interstitial space. A sill cap is installed on top of the composite inner wythe and the composite outer wythe, where the sill cap comprises a first curb to encapsulate a top portion of the composite inner wythe, a second curb to encapsulate a top portion of the composite outer wythe, and a central trough positioned between the first curb and the second curb. An anchor mechanism is inserted into the sill cap.

A concrete pump (1) includes a first frame (2a) equipped with a hopper (5) intended to receive the concrete, feet (13) for stabilizing the concrete pump (1) and a turret (10) carrying an articulated boom (6) comprising a plurality of arms (7). The articulated boom (6) carries at least one pipe (6a) for conveying the concrete between the hopper (5) and a concrete delivery location. The concrete pump (1) is equipped with any one of at least a first device for detecting cavities in the ground, a second device (22) for detecting an inclination of at least one arm (7) relative to a vertical axis (A2), a third device for detecting the deployment of the feet (13), a fourth device for detecting an attitude of the concrete pump (1) and a rotation sensor equipping the turret (10).

A foldable structure for supporting a 3D printer for building components, the foldable structure having expanded and compact positions includes: first supports spaced apart from each other in a first direction and extending in a second direction intersecting the first direction to support the foldable structure on a ground surface; second supports disposed respectively on the first supports, and being supported in a third direction for linear movement along the first supports in the second direction in the expanded position of the foldable structure; and a third support disposed between the second supports. The second supports include: shafts; and hinges disposed between the shafts and the first supports to tilt the shafts toward the first supports to transition from the expanded position to the compact position and to raise the shafts from the first supports to transition from the compact position to the expanded position.

A concrete construction made by 3D concrete printing having two or more layers of cementitious material extruded one above the other, and a reinforcing structure reinforcing the two or more layers. The reinforcing structure has at least two flexible longitudinal elongated steel elements running in lengthwise direction, and one or more flexible transverse steel elements forming an angle with the lengthwise direction so that these flexible transverse steel elements are present in the two or more layers. The structure also has a positioning element for positioning the at least two flexible longitudinal elongated elements and the flexible transverse steel elements, a polymer coating or yarns making stitches. The polymer coating or the stitches are applied on the at least two flexible longitudinal elongated steel elements, on the flexible transverse steel elements and on the positioning element thereby making a bond.

An automatic leveling system to maintain a 3D printer for building construction components in a substantially horizontal orientation includes: a support structure to support on a ground surface at least two columns each being supportable at a variable distance above the ground surface; a signal generator to generate a rotatable signal in a substantially horizontal plane; and sensors mounted on the columns to detect the rotatable signal. The variable distances are adjustable based on the detection of the rotatable signal by the sensors.

Construction systems for constructing a structure on a foundation and methods relating thereto are disclosed. In an embodiment, the construction system includes a rail assembly configured to be mounted to the foundation.
