The invention is an automated machine for reinforcement of piles, pillars, beams, and reinforcing cages in location of construction projects. This machine consists of main elements like loading arms and feeding jaws of longitudinal bars, rotating winch for stirrup and its guides, fixed and moving jaws and welding robot. It can be installed on a specified flat trailer in resting mode and come to an operative mode in project location and will be ready to use. To make reinforcing cages, an automated method for continuous winding of stirrup around longitudinal bars has been applied, and two intelligent welding systems (resistive spot and CO.sub.2 welding methods) have been utilized for joints in this machine.

There is proposed a reinforced concrete structure comprising a reinforcement assembly embedded therein, the reinforcement assembly including first and second lengths of chain, wherein the first and second lengths of chain being pretensionable prior to forming the concrete structure. The reinforcement assembly includes pretensionable member/s and/or resiliently deformable member/s intermediate of at least one tetherable end of the lengths of chain and a mounting block or link member.

A gripping device for handling reinforcement cages for tower segments of a wind turbine, comprising a gripper arm holding fixture and multiple gripper arms arranged radially on the gripper arm holding fixture. In particular, it is proposed that there is a coupling mechanism that can be connected with the reinforcement cage on each gripper arm, the length of the gripper arms can be telescopically motor-adjusted, the gripping device can be coupled with a lifting device that can be moved horizontally and vertically, and is adapted to move a reinforcement cage from apparatus for manufacturing reinforcement cages and/or to put a reinforcement cage down in a casing for creating a tower segment.

A product cover for the end of wire (1) of spacer meshes, and a processes and a systems for cover placement on ends of said wires (1), The wire ends of transverse wires are formed in a manner resulting in indentations and protrusions on their surfaces, so that the placement of a cover induces flow of its plastic material and creates a stable joining. Covers are serially guided inside a guide so that one of them is guided to a rotor. This rotor is then rotated to line up with the wire and a plunger for placement of the cover. Then, by the action of the plunger, this cover is pushed until fitted on the end of the wire.
