A device for stabilizing a concrete form includes an anchoring member with a channel aligned along a first axis, and elongate members with cavities aligned along a second axis, the elongate members coupled to form a frame. The device may include an anchoring post for insertion through the channel of the anchoring member to secure the device to a surface, and sliders with elongate bodies for insertion into the cavities of the elongate members, where the sliders are affixed to an engagement member structurally configured for engaging the concrete form. First retaining members may be structurally configured to engage the anchoring post when inserted through the channel of the anchoring member thereby maintaining a position of the frame along the first axis. Second retaining members may be structurally configured to engage a slider when inserted into the elongate member thereby maintaining a position of the slider along the second axis.

A three-dimensional printing system for reinforced concrete and a nozzle therefore. The system employs an extruder for extruding unreinforced concrete and a concrete reinforcement feeder is for feeding one or more elongate reinforcement members. The nozzle has an outlet and is operatively connected to the extruder and the concrete reinforcement feeder to receive the unreinforced concrete from the extruder and to receive the one or more elongate reinforcement members from the concrete reinforcement feeder. The nozzle combines the unreinforced concrete from the extruder and the one or more elongate reinforcement members from the concrete reinforcement feeder into a reinforced concrete extrusion and imparts the reinforced concrete extrusion through the outlet.

Method and apparatus for casting prefabricated concrete products with a substantially horizontal slipform casting process, where the concrete mass is fed in at least one feeding stage to a slipform casting mold compacting and defining the product to be cast, wherein at least one part is embedded in the concrete mass after the at least one concrete mass feeding stage and before the final compaction of the upper surface of the product to be cast.

A concrete construction (100) made by 3D concrete printing that contains: two or more layers (102, 106) of cementitious material extruded one above the other, and at least one elongated steel element (104) reinforcing at least one of the layers (102, 106). The elongated steel element (104) has an elastic and plastic elongation at break that exceeds 4%. The high elongation of the elongated steel element gives an increased ductility to the concrete structure (100).

The invention relates to an apparatus for constructing comprising at least feeding means for providing construction material in layers. The apparatus comprises at least first feeding means for hardening material, second feeding means for insulating material wherein said feeding means are configured to operate substantially concurrently so that a construction layer comprises materials from each feeding means. The apparatus may also provide reinforcement substantially concurrently with the other materials.
