Abstract: There are various pylons of wind power installations, primarily lattice mast pylons, tubular steel pylons or concrete pylons. In the case of pylons of concrete, there are various possible ways of producing same, inter alia also erecting pylons from ready-made reinforced concrete parts, wherein the individual ready-made reinforced concrete parts form respective segments which are laid one upon the other and which are then braced to each other._The object of the invention is to speed up construction of a pylon comprising segments disposed in mutually superposed relationship, with a bonding material between the segments._A pylon of a wind power installation, wherein the pylon comprises mutually superposed segments and there is a bonding material between the mutually superposed segments, and a heating element is provided in the upper region of the downwardly disposed segment and/or in the lower region of the upwardly disposed segment on the side of the segment, which is towards the oppositely disposed segment.

Abstract: The present invention relates generally to a connector assembly for connecting misaligned elongated members using a combination of a pivotable connection and a tolerant connection comprising a tolerance which accommodates the ends of misaligned elongated members. The connector assembly of the present invention connects pivotably to one or the other of the first or second elongated members and forms a tolerant connection with the other. The invention is described as applied to connecting an earth anchor driven into the ground with an extension rod connected to a structure requiring support, regardless of whether the earth anchor and extension rod are in functional alignment. The connector assembly forms pivotable and tolerant connections which cooperate to facilitate connection of the earth anchor to the extension rod, even after each has been affixed to a corresponding structure and are misaligned.

Abstract: Provided are segments of a spliced prestressed concrete girder, which have improved structural integrity at joints, and a method of manufacturing the segments. The method of manufacturing the segments, which are combined to build the spliced prestressed concrete girder, includes: manufacturing one or more joint blocks, each having a first end that has a shear key and is to be spliced to an end of an adjacent segment and having a second end that is bonded to a segment body of the segment; and manufacturing the segment body by using the one or more joint blocks as one or more ends of a formwork in which the segment body is to be made and by casting and curing concrete in the formwork, wherein the one or more joint blocks are fixedly bonded to one or more ends of the segment body in the manufacturing of the segment body.

Abstract: A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow tapered pole section modules, each module having a first open end and an opposed second open end. A cross-section of the second end is less than a cross-section of the first end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the second end of a first module with the first end of a second module. The first and second modules may have different structural properties, such that poles having desired structural properties can be constructed by selectively combining modules having differing structural properties.

Abstract: A beam for a shelter that can cover an area (12) that integrates a swimming pool, a terrace, etc., whereby the shelter includes a load-bearing structure that integrates the beam, on which covering elements are supported, characterized in that the beam (14) includes abutting segments (26) as well as at least one connecting element (28) of which a first end is connected to a first segment that is located at a first end of the beam and of which the second end is connected to a second segment that is located at the other end of the beam.

Abstract: Size tailorable tracks useful for connecting a first construction element (e.g., a transition molding) to a second construction element (e.g., a surface of a subfloor). In certain non-limiting embodiments, tracks which are scored during the manufacturing process to form weakened break junctions at which sections of the tracks may be separated by hand (e.g., typically “on site”) without the use of a cutting device. In certain additional, non-limiting embodiments, methods of using size tailorable tracks as well as track manufacturing systems, machines, and methods.

Abstract: The invention relates to a wind turbine tower comprising at least two annular tower rings placed vertically on top of each other. The wind turbine tower is characterized in that, a first tower ring overlaps at least a further tower ring of the at least two tower rings. The invention further relates to a wind turbine, a wind turbine tower elevator for use in a wind turbine tower and a method for assembling a wind turbine tower.

Abstract: A structural member such as a wind turbine tower comprising a plurality of elongated hollow pole sections secured together in an end-to-end relationship with each of the hollow pole sections comprising a plurality of longitudinally extending peripheral sections joined together. Each of the peripheral sections is bent along at least one longitudinally extending break line to define a plurality of angled wall sections extending between longitudinally inwardly extending edge portions. The edge portions of the peripheral sections are bolted together to form a hollow pole section.

Abstract: An embeddable breakaway utility pole comprises separate upper and lower aluminum pole pieces, wherein the lower pole piece is to be embedded below ground surface. The upper and lower pole pieces are interconnected by a weld which defines a breakaway zone enabling the upper pole piece to break off the lower pole piece in response to vehicular impact. The weld can be connected to a backer ring which provides a guide surface that axially aligns the pole pieces. Alternatively, the pole can be formed of a single pole piece which is welded between its ends to form a weakened region that defines the breakaway zone.

Abstract: An I-beam (10) comprises a first D-shaped flange (20) and a second D-shaped flange (60) connected by a web (100). Each flange includes a planar segment (30,70) and a curved segment (40,80). A lip (50,90) depends from the planar segment (30,70) of each flange (20,60) and is adapted to be attached to the web (100). The curved segment (40,70) of each flange (20,60) includes an outer surface (42,82) and an outer surface (44,84). The outer surface (42,82) is serrated to grip a wall panel or other structure attached to the flange (20,80) and the inner surface includes ridges (46,86) to strengthen the flange (20,60).

Abstract: A wind turbine tower is provided that will accommodate rail transport of wind turbine sections. The wind turbine tower includes a plurality of axial tubular sections, wherein the sections including an outer diameter no greater than a designated maximum diameter; a main structural element for each of the axial tubular sections, with the structural element being of a generally cylindrical shape; and corner reinforcements for the main structural elements. The corner reinforcements are provided generally equidistant around the circumference of the main structural element about 90 degrees apart. Corner supports may further be provided to support the corner reinforcements from a foundation of the wind turbine tower. With the corner reinforcements attached to the main structural elements, the combination falls within a space envelope that may be accommodated for rail transport.
