20100154332 | BASE MAT ASSEMBLY AND METHOD OF CONSTRUCTING THE SAME - A precast reinforced concrete base mat element, a base mat assembly and method for constructing a base mat assembly from a plurality of the base mat elements are described. The base mat element comprises a concrete body having first and second conduits extending there through in first and second generally perpendicular directions and a liner plate anchored in the concrete body. Preferably the concrete bodies have interlocking surfaces formed there on. A plurality of the base mat elements may be juxtaposed together with the interlocking surfaces interlocking with one another and with the tensile members extending through the first and second tensile conduits and being post-tensioned and anchored about the base mat elements to clamp the base mat elements together. The liner plates may then be welded together to form a a generally planar membrane. In one embodiment, at least one of the first and second tensile conduits is located above and one below the horizontal center planes of the concrete bodies to limit the base mat elements from displacing vertically relative to one another. | 06-24-2010 |
20100325986 | SYSTEM FOR JOINING A GONDOLA TO THE CONCRETE TOWER OF AN AEROGENERATOR - The present disclosure describes a system for joining a gondola to the concrete tower of an aerogenerator, wherein the concrete tower is formed by a lower annular section, one or several intermediate annular sections and an upper annular section, including a flat annular support which is inserted between an upper surface of the upper annular section of the tower and the lower surface of a yaw bearing that supports the gondola, the flat annular support comprising orifices wherethrough a plurality of joining means pass, each of which is fixed to the bottom of the upper annular section of the tower and to the bottom of the yaw bearing. | 12-30-2010 |
20140373466 | SHELL EXTENSION FOR NATURAL DRAFT COOLING TOWER - A system for increasing a cooling capacity of a cooling tower includes a shell extension and a tensioner. The shell extension is to extend a height of the cooling tower. The tensioner is to provide a tensioning force from the shell extension to a base of the cooling tower. | 12-25-2014 |

20090288355 | PRECAST COMPOSITE STRUCTURAL FLOOR SYSTEM - A precast composite flooring system utilizes girders and floor panels having steel lower structures placed in tension and concrete upper structures places in compression. Openings through a stem wall allow ducts, pipes, and conduits to be run therethrough. The system provides reduced weight over conventional precast or pour in place systems, allowing further reduction in the weight and size of other building components. The floor deck does not use tensioning strands, allowing openings to be formed at nearly any stage of construction and with reduced concern over cutting steel reinforcement. The floor panels and girders bolt together and bolt to a steel column frame, allowing for more efficient assembly. | 11-26-2009 |
20100000167 | MOVEABLE BARRIER - A moveable barrier includes a frame having a plurality of spaced apart frame members and a reinforcing layer fastened to at least one of the frame members. A first concrete portion at least partially embeds at least one of the frame members, and a foot assembly is attached to the frame. The foot assembly is rotatable from a stored position generally in-plane with the frame, to a deployed position generally normal to the plane of the frame. | 01-07-2010 |
20110113708 | METHOD FOR THE ASSEMBLY OF A TOWER AND TOWER - A number of pre-casted elements are stacked vertically to build the tower, while parts of the elements are forming the tower wall. Each element of the tower is fixed on its position and is connected with a tower foundation by a number of assigned post-tensioned cables. These cables are running inside the tower and they are pulled through the tower without embedding in dedicated channels. The post-tensioned-cables are fixed at certain points with the tower wall via damper-means to prevent their oscillation. | 05-19-2011 |

20130160384 | ELECTRONIC DEVICE ENCLOSURE - An electronic device enclosure includes a chassis and a cover. The chassis includes a fixing post and defines a receiving space configured to receive a storage device. The cover defines a latching hole. The fixing post is engaged in the latching hole to engage the cover with the chassis and cover the receiving space when no storage device is in the receiving space. | 06-27-2013 |
20130291462 | Tension Link for Drill Floor Substructure Assembly - The present invention relates to a new tension link drill floor level connection system for use on a drilling rig, as may be used in subterranean exploration. The present invention provides a tension link assembly for resisting separating forces incurred between sections of the substructure. In particular, the tension link assembly may be located at the drill floor level for resisting the separating forces imparted by “splayed” or wide leg mast structures that tend to separate substructure side boxes from the substructure center section. The present invention may be comprised of a first link element and a second link element with a tension link being connectable over the first and second link elements to resist separation between sections of the substructure. A latch mechanism may be utilized to prevent upward movement of the tension side boxes or center section relative to the drill floor or to one another. | 11-07-2013 |
20140260014 | STRUCTURES WITH INTERLOCKING COMPONENTS - Structures with interlocking components include a plurality of interlocking structure sections, each of the interlocking structure sections including at least one tensioning component and a plurality of compression components carried by the at least one tensioning component. The at least one tensioning component secures alternating ones of the plurality of compression components in adjacent ones of the plurality of interlocking structure sections in end-to-end, interlocking compression with each other. | 09-18-2014 |
20150376859 | Fatigue Resistant Foundation - A fatigue resistant gravity based spread footing under heavy multi-axial cyclical loading of a wind tower. The foundation having a central vertical pedestal, a substantially horizontal continuous bottom support slab, a plurality of radial reinforcing ribs extending radially outward from the pedestal. The pedestal, ribs and slab forming a continuous monolithic structure. The foundation having a three-dimensional network of post-tensioning elements that keep the structural elements under heavy multi-axial post compression with a specific eccentricity intended to reduce stress amplitudes and deflections and allows the foundation to have a desirable combination of high stiffness and superior fatigue resistance. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration. | 12-31-2015 |
