A variable height telescoping tower includes a base section and a second lower most section nested within the base section and extendable from within the base section. The second lower most section includes a plurality of vertically spaced lock apertures disposed thereon. A lock member is attached to the base section, and includes an engaging portion movable between a disengaged position at which the engaging portion rests outside of the lock apertures and an engaged position at which the engaging portion is engaged within one of the lock apertures of the second lower most section.

A transition body may be disposed between upper and lower tower sections of a tower for a wind power station. Some example transition bodies may include a substantially annular upper connection flange for connection to the upper tower section, and at least three substantially annular lower connection flanges, each of which may connect to a corner leg of the lower tower section. The transition body may have several segments disposed about a central tower axis, with the number of segments corresponding to the number of corner legs. Upper peripheral sections of the segments may form an annular circumferential connection envelope that supports the upper connection flange. Lower sections of the segments may form annular circumferential segment envelopes that support the lower connection flanges. The segments may be disposed at acute angles and converge into one another at or near the upper connection flange.

A supporting frame includes a truss composed of an upper straight frame member and a parallel lower straight frame member supported at their ends in spaced relationship relative to each other. At least two spans of divergent inclined brace member extend between them with the ends of the brace member spans each being securable to the upper or lower straight frame member by means of a fastener. Limited relative longitudinal movement of the upper and lower straight frame members is permitted before a fastener is secured to fix the positions at which the ends of the brace member spans are attached to the upper and lower straight frame members. In one application two trusses meet at a corner with a pylon being urged in the plane of the supporting frame into a corner between two frame members of each pair of trusses to extend at right angles to the frame.

A wind turbine tower wall having an orifice for accessing the interior of the tower, and an outer surface defined by generatrices; and a reinforcement frame joined to the tower in the orifice zone, and comprising least two parts joined one to each other. Each part has a mid-plane that is parallel to at least one generatrix, the mid-planes of at least one pair of adjacent parts forming an angle other than 180 therebetween. It enables the obtention of a frame more conformed to the curvature of the tower, combining savings in the material of said frame, greater optimization of the resistance of the tower and reduced stress concentration.

The present disclosure describes a base structural building module employing a core structural member having an array of upwardly and outwardly and downwardly and outwardly extending braces or arms extending therefrom. Tubular cans are mounted at the ends of each of the upper and lower arms to receive piles. One upper arm is aligned and paired with one lower arm and the pair's respective cans are aligned about their can axis. The modules employ flexible design by varying the lengths of the arms and their respective inclination or declination angles. Modules can be stacked one on top of another (and secured) to form multi-tiered structural building jackets for building vertical structures such as, for example, oil and gas platforms used onshore or offshore as well as other structures. Each tier can also comprise multiple modules joined laterally together to provide a wide variety of potential template configurations and building applications.

A combined member, comprising a communication rod (1) and a connecting rod (2), wherein the connecting rod (2) comprises a rod body (2.1) and a connector (2.2), the connector (2.2) being a fastening connector (3) or a sleeving connector (4), the rod body (2.1) of the connecting rod (2.1) and a rod body of the communication rod (1) being of a strip-shaped structure, the connecting rod (2) being connected to the communication rod (1) by the fastening connector (3) or the sleeving connector (4), the axis of the connecting rod (2) intersecting that of the communication rod (1) connected thereto. The combined member has the advantages of high bearing capacity, and convenient construction.

This application relates to tower segment handling methods and apparatus and, in particular, to methods and apparatus for handling segments of steel wind turbine towers. The wind turbine tower comprises a plurality of cylindrical vertical tower sections, which in the finished tower are mounted on top of one another. The vertical section of the tower has a longitudinal axis and comprises a plurality of wind turbine tower segments, the tower segments have vertical and horizontal edges and combine to form a complete vertical tower section by joining along their vertical edges. Adjacent vertical tower sections are joined to each other along the horizontal edges of the wind turbine tower segments. The tower segments are combined into a tower section using a flat roller bed on which the segments can be assembled. A method of assembling a tower section is discussed.

A structural tower for a wind turbine assembly, includes along at least a base section: a plurality of peripheral sections extending peripherally of a central section. Each includes a convex-shaped wall having two longitudinal side edges and an inner framework connected to a respective one of the convex-shaped walls and extending inwardly therein. The inner framework includes spaced-apart transversal structural members connecting the two longitudinal side edges of the convex-shaped walls together and pairs of connecting structural members extending inwardly towards the central section. Each connecting structural member of a pair has a peripheral end connected to a respective one of the longitudinal side edges and an inner end connected to an inner end of a respective one of the connecting structural members of an adjacent one of the peripheral sections to define a structural concavity in the structural tower between adjacent peripheral sections.

A cell tower is manufactured from a steel plate that is pressed into a polygon form, such as a 12-sided polygon or a 16-sided polygon. The tower is designed for direct embedding into the ground or attachment to a buried portion. The base portion contains apertures sized to permit the installation of an equipment rack directly into the interior of the tower. Other apertures in the tower provide handholes for installation of the equipment, backup batteries, and cabling. The top section of the cell tower includes mounting members for one or more sets of cellular radio antennas and/or microwave antennas. The antennas, and associated remote radio units, are mounted to the top of the cell tower and are hidden from view by one or more shrouds. The shrouds provide a visible barrier, but have minimal impact on the radio frequency characteristics.

The tower comprises: a wall having an orifice for accessing the interior of the tower, and an outer surface defined by generatrices; and a reinforcement frame joined to the tower in the orifice zone, and comprising least two parts joined one to each other. Each part has a mid-plane that is parallel to at least one generatrix, the mid-planes of at least one pair of adjacent parts forming an angle other than 180 therebetween. It enables the obtention of a frame more conformed to the curvature of the tower, combining savings in the material of said frame, greater optimisation of the resistance of the tower and reduced stress concentration.
