Abstract: A floating platform for high-power wind turbines, comprising a concrete substructure, said concrete substructure forming the base of the platform, which remains semi-submerged in the operating position, and consisting of a square lower slab on which a series of beams and five hollow reinforced concrete cylinders are constructed, distributed at the corners and the center of said lower slab; a metal superstructure supported on the concrete substructure and forming the base for connection with the wind turbine tower, said tower being coupled at the center thereof; and metal covers covering each of the cylinders, on which the metal superstructure is supported and to which vertical pillars are secured, linked together by beams, which join at the central pillar by an element whereon the base of the wind turbine tower is secured.

Abstract: Road safety barrier comprising: concrete bottom parts (1); concrete top parts (2) coupled on the bottom parts (1), and attaching means (3, 31) of the successive top parts (2) at their opposite ends. The bottom parts (1) have an upper surface provided with a longitudinal channel (11) for coupling in the longitudinal direction and with the possibility of limited vertical displacement of a longitudinal extension (21) protruding from a lower surface of the top parts (2); the channel (11) and the extension (21) have similar cross-sections and dimensions calculated so that the top part performs a lateral rotation of a determined amplitude, in the event of a vehicle impact, and absorbs a significant part of its kinetic energy.

Abstract: A threaded anchor for ice climbing, comprising: —a screw with a cylindrical tubular body, a number of cutting teeth, a rearward perimetric protruding threaded section; —a clamp disposed exteriorly with regard to the screw and comprising an operating component, displaceable between: a locked position, where the tightening of the clamp and the fixing thereof at any point along the length of the screw is established, and an unlocked position, enabling the turning of the clamp with regard to the screw and the positioning of the clamp at any point along the length of said screw; —a folded strap attached by its first end to the clamp and presenting at its second end a closed loop for the mounting of a carabiner suited for the hitching of the climbing rope in its position of use or of a harness of the climber in an inoperative position.

Abstract: The invention relates to a method for building concrete foundations for lattice-type offshore structures and to foundations built using this method, which has the main aim of replacing the piles used to anchor lattice structures to the seabed (7) with blocks of on-site reinforced concrete (1) which grant the necessary stability to the lattice structure (2), doing away with all pile-driving works but without performing any structural modification of said structure. Said elements (1) are positioned using templates (12). The advantages of this novel invention lie in the possibility of installation on any type of terrain, providing a perfect connection between the seabed and the foundations thanks to on-site concreting, as well as its ease of construction, reduction of noise emissions and of auxiliary means.

Abstract: A joining device of a metal segment to a concrete segment of a hollow tower. The joining device is formed by a set of bolts passing by one of its ends by holes of an anchoring ring and attached to its both sides by a first set of nuts and arranged to be attached by its other end to the base of the metal segment by a second set of nuts. The anchoring ring includes a set of connectors extending externally and internally thereto in a substantially perpendicular direction to the bolts and arranged so do not interfere with reinforcement. The invention also refers to a hollow tower comprising at least one metal segment joined to a concrete segment by the joining device.

Abstract: The tower, applicable in the installation of wind turbines, comprises: a lower end (11) having a general polygonal configuration formed by flat sides (12) and cylindrical portions (13) arranged between consecutive flat sides (12); the flat sides (12) having a decreasing width in the upward direction throughout the tower (1), and the cylindrical portions (13) having an invariable shape throughout the tower (1); the tower (1) having, at its top end (11), a circular outline made by the cylindrical portions (13), which maintain an invariable shape throughout the tower (1). The invention includes a climbing formwork device for building the tower.

Abstract: The system comprises a limited number of equal groups of formwork pieces, each group comprising: —intermediate pieces (1) of constant curvature and width along the entire length thereof and—end pieces (2) forming two symmetrical lateral corners of triangular or trapezoidal outline, with a curvature equal to that of the intermediate pieces. This system allows for forming, with the same groups of pieces, successive formwork segments of varying or constant section for building towers. The invention also includes a building method and the tower thus obtained.
