The present invention corresponds to a device for positioning elements along a support body, comprising a first plate with a groove on its perimeter and a second plate with a groove on its perimeter, the first plate is in contact with the second plate, wherein the groove of the first plate and the groove of the second plate are coincident, and in which the positioning elements are arranged between the grooves of the first plate and the second plate. Additionally, the first plate and second plate have fastening means allowing them to be fastened to the support body.

The present invention discloses a prestressed-bolted dry-assembled segmental precast hybrid tower with grouting-free, comprising a top steel tower tube, a reverse self-balancing steal-concrete transition section, and a prestressed-bolted dry-assembled segmental precast concrete tower with grouting-free dry fast splicing and a gear reinforced wind turbine foundation; the steel tower tube, the steel-concrete transition section, the concrete tower tube and the hollow wind turbine foundation are integrally connected from top to bottom through a prestressed steel strand system to improve the overall bending resistance of the tower; the upper end of the prestressed steel strands is anchored to the steel-concrete transition section, and the lower end is anchored to the bottom face of the wind turbine foundation corbel; the concrete tower tube is composed of a number of segmental tapered precast concrete tower segments, which are grouting free spliced vertically, and the vertical splicing utilizes positioning pins to accurately position the installation position. The prefabricated concrete tower tube segment is formed by a number of circular arc-shaped prefabricated concrete pipe segments with circumferential grouting free dry splicing. The segments are spliced into a whole by prestressed bolts and then installed staggered from top to bottom to enhance the shear resistance.

The present disclosure is directed to an internal reinforcement assembly for a tower of a wind turbine. The reinforcement assembly includes a plurality of reinforcing rod members spaced circumferentially about the tower. Each of the plurality of reinforcing rod members includes a first end and a second end. The reinforcement assembly also includes an adjustable mounting component configured with each of the second ends of the plurality of reinforcing rod members. As such, the adjustable mounting components are mounted to an interior wall of the tower at a location to be reinforced. Thus, the reinforcing rod members interact with the tower to reinforce the tower at the location to be reinforced.

A wind turbine with a tower is provided, which has at least one first and second tower segment. The first tower segment has a steel wall and at least one first opening in the steel wall. Further provided is a reinforcing element with a cured casting compound around an area of the first opening.

Aspects of the disclosure are directed to a multi-functional streetlight. In accordance with one aspect, the multi-functional streetlight includes a hexagonal shaped support structure, wherein the hexagonal shaped support structure includes an arm segment and wherein the arm segment includes a luminaire on an under side of the arm segment; and a base flange configured to couple the hexagonal shaped support structure to the ground.

A mounting post of variable length that may be attached between a local floor and ceiling. The mounting post may include a cable access hole near respective upper and lower extremities of the mounting post.

Spiral forming devices, systems, and methods can be used to join edges of a of a stock material, in a curved configuration, along one or more joints to form tubular structures, such as conical and/or cylindrical structures (e.g., frusto-conical structures). A planar form of the stock material can be formed from a plurality planar sheets coupled to one another in an abutting relationship. By controlling relative orientation and shapes of the plurality of planar sheets forming the stock material and/or by controlling a position of a roll bender used to curve the planar form of the stock material into the curved configuration, the curved configuration of the stock material can be controlled through transitions between sheets to facilitate rolling the sheets to a desired diameter with a reduced likelihood of dimples or other errors and to facilitate fit up between adjacent sheets in the curved configuration.
