A method for producing a prefabricated 3D-printed part includes depositing a layer of a particulate aggregate on a production panel by a layer-depositing device; and dispensing a predetermined dose of a binder or a water/binder mixture, comprising water and at least one hydraulic binder, onto a locally predetermined region of the layer of the aggregate by a printhead. At least one reinforcement is arranged by a reinforcement-depositing device, at least in some regions, on and/or in the locally predetermined region on which the predetermined dose of the binder or the water/binder mixture was dispensed during the course of the second method step.

Apparatus (10) for vertical (72) slip forming of concrete walls and columns (55). The apparatus comprises an attachment portion (23) for a frame with a slipform assembly inside comprising an extrusion form providing side walls defining a cavity and actuators (20) to adjust the position of the side walls forms essentially arranged along the longitudinal axis of the slipform assembly. A concrete supply (45) is connected with the slipform assembly for delivering concrete (52, 53, 54) to that cavity through the top open surface. A mechanism (20) is provided for vertically displacing (72) that slipform assembly incrementally relative to the frame. Thus, a concrete structure (55) having a vertical orientation is continuously cast. The actuators (20) adjust the position of the side walls during the incremental vertical movement (72) of the slipform assembly to create new forms for a column or wall with variable diameter, variable form and/or twisted.

A device for fabricating structures of large dimensions, layer by layer.

The invention relates to a device making use of positioning an extrusion head in three dimensions by means of cables in order to deposit a pasty material continuously in thin layers, e.g. a mortar comprising either a hydraulic binder or thermoplastic compounds or thermosetting compounds or curable compounds.

The invention is for making industrial elements of very large dimensions, and more particularly for making buildings.

The present relates to an apparatus for manufacturing 3-dimensional concrete structures comprising a projection head (1) for spraying concrete material, wherein the projection head (1) comprises a projection nozzle (11) for spraying the concrete material and at least two guiding surfaces (12) provided on both sides of the projection nozzle (11) and defining a volume in between, such that the projection nozzle (11) is adapted to spray the concrete material into said volume, and wherein the projection head (1) is repeatedly moved along a predefined path by a control means and is configured to adjust the position of the two guiding surfaces (12) during the movement of the projection nozzle (11) so as to create a 3-dimensional concrete structure made of a plurality of projected concrete layers.

Apparatuses and methods associated with creating a form to construct a concrete structure (e.g., a concrete building). In embodiments, an apparatus may comprise a number of forming system components, including but are not limited to a plurality of fixed or adjustable posts; a plurality of fixed or adjustable roof struts, a plurality of fixed or extensible frames; and/or a plurality of mounts. The fixed/adjustable posts, the fixed/adjustable roof struts, and the fixed/extensible frames are selectively and adjustably coupled together to create a form of selected dimensions to construct the concrete structure/building on site with reduced number of pours, e.g., a single pour. Other embodiments may be disclosed or claimed.

Disclosed are a fully assembled, fully cast-in-place, composite-type house and a construction method thereof, comprising providing at least one layer of house main body on a house foundation, wherein each layer of the house main body comprises: a tension bearing system which constitutes a wall body (1) or floor slab (2), a stabilizing function system for the tension bearing system, a system which constitutes a heat-insulating layer and a fire-proofing layer and is used as a formwork and has the function of supporting, and a pressure bearing system which connects together the afore-mentioned systems by means of a fully cast-in-place technique. The fully assembled, fully cast-in-place, composite-type house and the construction method thereof integrate structural component specifications, the overall stability of the house is good, and energy-saving and environmental protection requirements are satisfied.

The present invention is directed generally at three-dimensional printing and more particularly to using three-dimensional (3D) printing to produce concrete and concrete-like (i.e. hempcrete) structures. Recently, 3D printing has advanced to the point where it is now possible to 3D print more complex concrete structures, such as homes. Unfortunately, prior art methods of 3D printing concrete structures have numerous drawbacks. For example, many existing systems suffer from excessive mechanical complexity and/or are susceptible to jamming (e.g. caused by dirt getting into delicate mechanisms). Other problems include difficulty with field maintainability, a lack of horizontal and vertical construction scalability, excessive weight and/or difficulty in printing structures on uneven or difficult ground. Also, existing devices are difficult and time consuming to assemble and disassemble in the field, thereby increasing project costs. The present innovation successfully addresses all of these limitations.
