A module for the production of concrete parts has a row of displacement bodies that are adjacently arranged in a horizontal longitudinal direction (L) and that are clamped captively to a grid structure made of at least two individual grids running in the longitudinal direction (L). Surfaces of the grids are oriented in a transverse or inclined manner in relation to the horizontal. Each of the grids has at least a first and a second longitudinal bar arranged at a distance in parallel to one another and running in the longitudinal direction (L) and a plurality of transverse bars being arranged at a distance from one another and oriented in a transverse or inclined manner in relation to the horizontal. The transverse bars are respectively connected with the longitudinal bars. One of the displacement bodies for each grid has a first and a second retaining device.

Method for installing a hollow concrete tower comprising the following steps: a) arranging a platform on a site; b) arranging on said platform at least one partial full-segment mould in a position such that the segment axis of the segment being cast in said mould is substantially vertical; c) pouring concrete inside said arranged partial mould(s); d) allowing the poured concrete to set to working strength, generating corresponding segment(s); e) removing the arranged mould(s) with concrete set to working strength, to leave the corresponding segment(s) exposed; f) assembling said corresponding exposed segment(s); and g) optionally, repeating steps b)-f) at least once.

A steel reinforced concrete column for a high rise building comprises a plurality of hot-rolled steel sections extending longitudinally through the concrete column. Each of these steel sections has an outward flange with an outer surface turned outwards in the concrete column, an opposite inward flange with an outer surface turned inwards in the concrete column, and a web connecting the outward flange to the inward flange. The steel sections are arranged in the concrete column so that the outer surfaces of their inward flanges at least partially delimit therein a central concrete core with n lateral sides and a transversal cross-section that forms an n-sided polygon, n being at least equal to three, and each of then lateral sides of the central concrete core being coplanar with the outer surface of the inward flange of at least one steel section.

The present invention provides a rebar cage module comprising a first opening rebar net and a second opening rebar net. The first opening rebar net extends from a central direction, and partially forms an elongated groove shape enclosing a first accommodating portion, and has a first opening. The second opening rebar net extends from the central direction, and partially surrounds the central direction to form an elongated groove shape, and has a second opening oriented to the opposite direction with the first opening. Wherein, the first opening rebar net at least partially covers the second opening rebar net, the first opening rebar net is at least partially distributed in the second opening, and the first opening rebar net extends at least partially through the second opening into the second accommodating portion, and making the first accommodating portion and the second accommodating portion at least partially overlap.

A stirrup module comprising an outer stirrup set, an upper-opening stirrup set having an upper opening and provided in an opening of the outer stirrup of the outer stirrup set, and a lower-opening stirrup set having a lower opening and provided in the opening of the outer stirrup of the outer stirrup set. Wherein the upper opening and the opening of the outer stirrup are oriented in the same direction, the lower opening and the upper opening are in opposite directions to each other. Wherein the upper-opening stirrup set has a first bottom of stirrup opposite to the upper opening, and the first bottom of stirrup corresponds to the position of the lower opening; the lower-opening stirrup set has a second bottom rib opposite to the lower opening, and the second bottom rib corresponds to the position of the upper opening.

A stirrup module includes first, second, third and third erect bar portions, a bottom rib section. The second erect bar portion is arranged in parallel with the first erect bar portion. The third erect bar portion is arranged in parallel with the first erect bar portion and located between the first and second erect bar portions. The fourth erect bar portion is arranged in parallel with the first erect bar portion and located between the third and the second erect bar portions. A first gap is between the first and third erect bar portions, and a second gap is between the second and fourth erect bar portions. The bottom rib section connects at least portion of the bottom ends of the first, second, third and fourth erect bar portions, and the first and second gaps are each formed with an opening at the end opposite to the bottom rib section.

Various implementations include methods and apparatuses for constructing a concrete structure. In one implementation, a structure includes a pre-cast concrete column section and a pre-cast concrete beam section. The column section includes an embedded first assembly with a threaded rod, and the beam section includes an embedded second assembly defining a channel for receiving the threaded rod. Grout is fed through a joint between the column and beam sections into the second assembly to couple the threaded rod with the second assembly. The grout is urged through the joint and the second assembly by gravity and by applying vacuum suction to a grout port defined by the second assembly. The grout port extends between the channel of the second assembly and an external face of the beam section.

The invention has for object a method for manufacturing concrete construction blocks (6) for a wind-generator tower made up of at least two consecutive blocks secured to one another by a contact surface of each of the two blocks, the manufacturing method comprising the following steps: pouring concrete into a first cage of reinforcements (10-1) so as to obtain the first concrete construction block comprising a first contact surface (9), and pouring concrete into a second cage of reinforcements (10-2) so as to obtain the second concrete construction block, the second cage of reinforcements being provided in a form (21) arranged such that the first contact surface (9) of the first block (6-1) makes up a wall for delimiting (26) the pouring of the concrete such as to form a contact surface (9) of the second block (6-2).

Feed segments within an adjustable feed matrix may be vertically adjusted, horizontally adjusted, and adjusted for rebar thickness. The adjustable feed matrix may be used in rebar structure building. A feed column may include a plurality of feed segments. Each feed segment may include a feed input and a feed output connected by a feed cavity. The feed cavity can include a feed mechanism and/or stabilizing mechanism that allows different thicknesses of rebar to consistently pass through the feed segment to the feed output. A vertical adjustment may adjust vertical spacing of the segments and increase or decrease vertical spacing of the feed outputs, enabling different vertical spacing between rebar passing through segments of the feed column. The feed column may attach to a rail through a coupling. The coupling may be released through a horizontal adjustment, enabling the feed column to slide along the rail and adjust horizontal spacing of the feed outputs.

A method for manufacturing a continuous stirrup and an apparatus for implementing such method are provided. The method includes placing a planar structure formed of a wave-shaped rebar on a platform, fixing a side of the planar structure and using an elongated mold to abut against the other side of the planar structure to form an intermediate structure, flipping the intermediate structure, and abutting the elongated mold against the side of the planar structure to form a continuous stirrup.
