Abstract: An above-ground low-temperature tank includes a metal inner tank which stores low-temperature liquefied gas, and an outer tank which includes a concrete outer wall surrounding the inner tank. A hole portion which has a preset depth from a bottom surface of the inner tank is formed on a bottom portion of the inner tank, and a metal pit main body having a cylindrical bottomed accommodating portion is provided in a state where the accommodating portion is accommodated in the hole portion. A reinforcing body which supports at least an outer circumferential edge portion of a bottom surface of the pit main body is provided on the bottom surface side of the pit main body in the hole portion. A cold insulation material is provided below the reinforcing body.

Abstract: A foundation for a wind turbine tower, provided with a central accommodation for accommodating and firmly constraining, by means of threaded bars projecting from such central accommodation, an actual wind turbine tower, made of steel or concrete, is entirely prefabricated and includes at least two prefabricated structural elements, modular and monolithic, made of reinforced concrete, approached in sequence, shape-coupled, and subsequently constrained to each other, at least at such central accommodation, by a series of post-tension cables arranged in respective through-holes, so as to make the entire foundation monolithic.

Abstract: A concrete storage tank structure comprises a tank including a floor slab having a periphery and a wall having inner and outer faces extending upwardly from the floor slab at a position adjacent the periphery of the latter. The tank structure further includes a shear pad extending outwardly away from the tank from a position adjacent a lower portion of the outer face of the wall. The shear pad and the tank are positioned relative to one another in such a way that a space is provided therebetween and a number of elongated flexible connecting elements are arranged so as to extend through the space in interconnecting relationship relative to the shear pad and the tank. A strip of resilient neoprene elastomeric material is disposed in the space. The shear pad is thus flexibly attached to the tank in such a way that the forces imposed on the wall of the tank by the shear pad during movement of the tank during use are minimized.

Abstract: An LNG system generally comprises a primary container, and a secondary container positioned around the primary container. The secondary container generally comprises a first end wall, a second end wall, and at least two side walls. At least one of the walls is fabricated from a plurality of prefabricated wall panels. Each of the wall panels is fabricated from a combination of concrete and steel. The wall panels are preferably prefabricated offsite, and then transported to the construction site where they are adjoined together in end-to-end fashion to form walls. A method for constructing a full containment LNG system is also provided. In one embodiment, walls and a roof for a secondary container are assembled, but leaving an end open. At least one primary tank is brought into the secondary container. A second end wall is then erected to form the enclosure for the secondary container.

Abstract: A device for controlling the atmosphere in a space (16) which is partly delimited by at least one glass component (12, 13; 61) and which is separated from the environment (17, 18), with at least one connection between the space and the environment, and with at least one electrically actuatable valve (32, 33; 47, 48) associated with the connection, which valve is connected to an electric control unit (24); the valve (32, 33; 47, 48) is arranged in a connecting passage (34) within a member (15A) delimiting the space (16), namely in the case of an insulating glass assembly (11), a connecting ledge (15) arranged between two glass panes (12, 13) or, in the case of a lamp (60), in a socket (64), and the control unit (24) provided for an automatic actuation of the valve is also arranged in said member (15A).

Abstract: A prefabricated storm shelters that can be easily repositioned and assembled while providing safe, secure shelter before, during and after a catastrophic event are described, as well as a method to mfr. them.

Abstract: The invention relates to containers, particularly to containers for storing dry granules and powders, for examples silos.

Abstract: A device for connecting bars end-to-end includes a hollow body having an internal cavity with at least one bar insertion opening and a longitudinal axis extending through the at least one insertion opening, and a plurality of radially adjustable clamping elements. The device further includes at least one locking element movably arranged inside the hollow body. The internal cavity of the hollow body has at least one slope inclined relative to the longitudinal axis of the hollow body. The at least one locking element has an inclined face that matches the profile of the at least one slope and a gripping face with at least one protrusion.

Abstract: A rectangular tilt-up concrete tank includes a concrete slab with a metal plate anchored thereto, the metal plate defining at least one substantially linear concrete side wall location. A plurality of preformed concrete side panels each having metal plates attached along a bottom edge and opposing side edges are welded in a liquid-tight weld to the metal plate defining the concrete side wall location and a side metal plate of each side panel is welded to a metal side plate of an adjacent side panel in a liquid-tight weld to define a concrete side wall. Horizontal and vertical post-tensioning sleeves are provided in the side panels for receiving post-tensioning tendons.

Abstract: A precast panel for building reinforced concrete walls has a metal liner that forms a front surface of the panel. A concrete mass is disposed behind the liner. The panel has reinforcement structure within the concrete mass that can be used to provide continuity of reinforcement between adjacent panels. Edges on the concrete mass are recessed, facilitating the connection of a splice end on a reinforcing bar with a splice end on an adjacent panel. The liner, reinforcement structure, and concrete mass form a composite steel-concrete structure.

Abstract: A joint made between prestressing strands with a prestressing strand coupler is covered with a transparent coupler sheath having a retarded-hardening resin filling material injection opening and discharge opening provided in a tube wall thereof, and a resin filling material is injected into the transparent coupler sheath from the injection opening to fill the coupler sheath with the filling material. Thereafter, the whole outer peripheral portion of the prestressing strand joint, including the coupler sheath, is embedded with placed concrete. Tension is applied to the prestressing strands after the concrete has hardened and before the resin filling material hardens, thereby completing an excellent prestressing strand joint structure.
