The present invention relates to an apparatus for manufacturing a 3D element of an architectural structure. The apparatus includes: a transfer arm unit installed movably along 3D locations; a material supply unit placed at one side of the transfer arm unit to supply construction materials necessary for the manufacture of the architectural element and fillers necessary for the formation of a space in the architectural element; and a control unit controlling the operations of the transfer arm unit and the material supply unit while moving in response to positional information included in data on the shape of the architectural element such that the construction materials and the fillers are stacked on a base plane where the architectural element is to be manufactured. The control unit controls the supply of the construction materials to locations corresponding to the element of the architectural structure and the supply of the fillers to locations corresponding to the space defined by the architectural element.

A mobile 3D printing device, system and method based on the addition of material intended to be attached to a lifting device with a single lifting cable or chain, including a printing head adapted to receive material and depositing it; fixing means adapted to link the printing head to the lifting device, and stabilization means adapted to stabilize the position of the printing head by a gyroscopic effect.

The printing device enables the control of the printing of a structure to be printed, in particular the position of the printing head, to reduce the labor costs and the time to install such a device on a standard crane provided with a hook.

A robotised construction system is provided that includes a cartesian robot that can be automatically lifted as the construction is becoming higher, that is provided with a system of robotic supply of the materials and of the electric and electronic installations and that is provided with specific fabrication tools which work some by the contribution of layers of fluid construction materials. In a cement-based usage in which the cement is setting and having been deposited, by projection of these same materials and others by forming and placing construction elements in a determined position.

A self-climbing concrete wall form hoist for forming a concrete wall section atop a previously formed wall section has a wall mounting releasably secured to the previously formed wall section, a plurality of moveable vertical masts, an extendable cylinder inside each mast, and a platform alternatively supported on the masts, which in turn are supported alternatively on the upper and lower wall mountings. The apparatus cycles between a platform raising position when the masts and platform are supported on the upper wall mounting and a lower wall mounting raising position when the masts and platform are supported on the upper wall mounting. The extendable cylinders are extended to raise the mast and platform relative to the lower wall mounting when the masts are supported on the upper wall mounting, and the extendable cylinders are retracted when raising the lower wall mounting relative to the platform when the masts and platform are supported on the upper wall mounting. The self-climbing concrete wall form hoist can descend a wall by effectively reversing the steps required to complete wall climbing.

An additive printing device and a method for using the same to manufacture a tower structure of a wind turbine is provided. The additive printing device includes a vertical support structure, a support ring suspended from the vertical support structure, and a printer head movably coupled to the support ring for selectively depositing cementitious material. A drive mechanism, such as a rack and pinion, moves the printer head around the support ring while selectively depositing cementitious material. The vertical support structure may be raised and/or the relative position between the vertical support structure and the printer head may be adjusted to raise the printer head to print subsequent layers. This process may be repeated to print the tower structure layer-by-layer from the ground up.

A system for manufacturing a tower structure of a wind turbine includes an additive printing device having a central frame structure with a platform and an arm member. The arm member is generally parallel to a longitudinal axis of the tower structure. The additive printing device also includes a plurality of robotic arms secured to the arm member of the central frame structure. Each of the robotic arms includes a printer head for additively printing one or more materials. The additive printing device further includes at least one nozzle configured for dispensing a cementitious material. Moreover, the system includes one or more molds additively printed via the additive printing device of a polymer material. As such, the mold(s) define inner and outer wall limits of the tower structure. After the mold(s) are printed and solidified, at least one of the printer heads or the nozzle of the additive printing device is configured to dispense the cementitious material between the inner and outer wall limits of the tower structure.

The invention relates to a boom arm for mobile concrete pumps and to a mobile concrete pump. The boom arm, having a first and second end, wherein at least one elbowed section, in which the main bending loads which occur during proper use act as torsional loads, is provided between the first and the second end of the boom arm, is made from a fiber composite material, wherein beyond the elbowed region the height of the boom arm in cross-section is greater than the width of the boom arm in cross-section and in the elbowed region the width of the boom arm in cross-section is greater than or equal to the height of the boom arm in cross-section. A concrete pump with a placing boom, arranged on a substructure, comprising at least two boom arms, at least one of which is designed according to the invention.

A slurry dispense system utilizes a buffer chamber to release the pressure from the supply pump, and buffer the irregular flow rate of the supply pump. It also utilizes a positive displacement pump to control the dispense flow. With the help of the buffer chamber, the positive displacement pump is able to provide a constant flow rate, and can be accurately controlled. A high resolution and a high speed can be achieved at the same time.

A method of manufacturing a tower structure includes printing and depositing, via a printhead assembly of an additive printing system, one or more printed layers of a wall of the tower structure. The method also includes unwinding at least one continuous roll of a reinforcement material to form at least one continuous reinforcement ring member layer, the reinforcement material comprising a pultruded polymer material. Further, the method includes placing the at least one continuous reinforcement ring member layer atop the one or more printed layers of the wall of the tower structure. Moreover, the method includes printing and depositing, via the printhead assembly of the additive printing system, one or more additional printed layers of the wall of the tower structure atop the at least one continuous reinforcement ring member layer.

A method for manufacturing a tower structure, the method including printing and depositing, with at least one variable-width deposition nozzle of a printhead assembly, one or more layers of at least one wall element of the tower structure, the at least one wall element having an outer circumferential surface and an inner circumferential surface. The method also including forming, with the at least one variable-width deposition nozzle, at least one void into the at least one wall element.
