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).

The object of the invention is the device for automatic reinforcement of structures, especially concrete structures, which has: —a manipulator (1) with the means for precisely moving it in space, —a printhead located on the endpiece of the manipulator (1), —a reinforcement fibre storage unit (2) in the form of a reel, located preferably on the printhead, characterized in that the reinforcement fibre storage unit (2) is connected to the means for laying the fibre on the surface of the structure being reinforced, where said means have drive rollers (4) and a cutting knife (5). The object of the invention is also the method for automatic reinforcement of structures, where said method uses a remote-controlled device.

A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.

A precast concrete wall structure and method for forming a wall structure are disclosed. A forming member is positioned within a casting bed. The forming member comprises a layer of insulating material defining a plurality of integrally-formed rectangular protrusions extending in a parallel and spaced-apart relationship to one another to define a plurality of rectangular-shaped channels therebetween. The forming member also defines at least one cutout for defining a first portion of a fastener for securing the wall structure to a support structure. A second portion of the fastening member is positioned within the cutout. Uncured concrete is placed within the casting bed and allowed to cure.

A lid for a utilities vault having a moldable core and a reinforcement matrix positioned within the core, the reinforcement matrix including longitudinally and laterally extending intersecting members and a plurality of lid feature housings positioned on and attached to the intersecting members, the lid feature housings extending through the core and protruding to the upper and lower surfaces of the lid, and the plurality of longitudinally and laterally extending intersecting members have a height sufficient to provide reinforcement without a perimeter member for the reinforcement matrix.

An apparatus and method for precision forming a precast concrete flight of stairs is disclosed and where precision cut form components provide plural tread supports, plural sideboards, plural tread/riser combinations and a center tread support that upon assembly, the form components, automatically square and align treads and risers with upper and lower landings for installation to provide access between vertically spaced apart floors of a structure.

A wall structure and a method for forming a wall structure is provided using three-dimensional printing of extruded building material applied to a surface of a building structure. According to one embodiment, the wall structure includes a pair of outer wythes spaced from an inner wythe. The outer wythes can include a core extending between the pair of outer wythes and toward the inner wythe. A protrusion can also extend toward the inner wythe a spaced distance from the inner wythe or entirely toward and adjoining the inner wythe. The core is configured with an inwardly facing spaced opposed surfaces of the outer wythes surrounding a vertically extending rebar, with grout surrounding that rebar. Horizontally extending support pins can be spaced parallel from each other and extend from the protrusions and into the inner wythe.

Method of forming track section includes coupling functional components to a framework. At least some of the functional components are arranged in a precise and accurate arrangement in a common plane. Building a rigid, removable, and reusable mold around the framework and functional components. Steel reinforcement (“rebar”), which is bent into a shape corresponding to a track section profile, is provided within the mold. Dispensing a binder material into the mold and curing the binder material; and removing the mold from the cured binder material to reveal a completed track section at required accuracy set by the framework. At least some other functional components are arranged parallel to each other in a first lateral plane normal to the common plane and at least still other functional components are arranged parallel to each other in a second lateral plane normal to the common plane and parallel to the first lateral plane.
