The invention relates to a removable deflector for protecting the feet of a structure, which corrode following infiltration of water under the bottom plates and which weakens these areas. The invention concerns a removable device enabling the positioning of protection for the feet of storage tanks without a shut-down of production. The device according to the invention is a deflector element and a deflector assembly consisting of a plurality of deflector elements, capable of being positioned one after the other in order to surround the feet of the wall of the structure. Each deflector element comprises at least one downward-sloping protective plate (1), at least one flexible sealing gasket attached along the upper edge of this plate (1), and: at least one retaining arm (5) for same, wherein one of its ends is fixed to the so-called upper edge of said plate (1) and the other so-called distal end is capable of being rigidly and reversibly attached to an element of said structure and to be detached therefrom, this arm allowing the adjustment of the pressing of the sealing gasket against the wall (14) of the tank, and at least one support (6) arranged towards its lower edge and separable into at least two parts suitable for making the deflector removable, of which the upper one is attached underneath the plate (1) and the other, lower one, is attached to the support slab (23) of the structure wall (14).

A floating roof assembly includes longitudinal girders, and floating members arranged in rows that alternate with the longitudinal girders. Upper and lower press bars are disposed across and fixed to the longitudinal girders. Each of the upper and lower press bars has fastening holes each of which has a first hole portion and a second hole portion. Fastening members connect the upper and lower press bars to the longitudinal girders through the fastening holes. When the fastening members reach the second hole portions of the upper and lower press bars, the longitudinal girders can increase a clamping force thereof to clamp the floating members.

A fluid storage tank includes a plurality of end panels defining a plurality of curved wall sections and a plurality of side panels extending between and connecting the plurality of curved wall sections. The plurality of end panels and plurality of side panels define a perimeter wall. The fluid storage tank further includes a plurality of cable arms, each of the cable arms connected to a flange of at least one of the plurality of end panels or side panels, and at least one upper tension member having a first end connected to one of the plurality of cable arms and a second end connected to another of the plurality of cable arms.

A parts assembly, a tank, and a panel discussed, including a first wall; a second wall, a first edge of the first wall facing a second edge of the second wall; a first flange connected to and extending outward from the first wall; a second flange connected to and extending outward from the second wall, the second flange being spaced from and disposed opposite the first flange; at least one fastener extending through and connecting the first flange and the second flange, the at least one fastener being pre-tensioned; and at least one rigid spacing member disposed between the first flange and the second flange, the rigid spacing member being spaced from the at least one fastener, the rigid spacing member being in contact with the first and second flanges, the at least one fastener being disposed between the rigid spacing member and the first and second walls.

The invention relates to a combination of a foundation anchor and energy damper for vertical tanks or similar containers for liquids with a thin wall and continuous support, comprising an energy dissipation component centrally connected to a foundation anchor component by means of a linking component, the energy dissipation component comprising one or more superimposed and horizontally arranged energy dissipating plates with a rhombic shape truncated at the vertices thereof, wherein the shorter diagonal is normal to the wall of the tank and the side ends or vertices corresponding to the longer diagonal have quadrangular extensions for support on a load transmission component that is connected to the wall of the tank so as to transmit and distribute the forces developed by the one or more energy dissipating plates. Alternatively, the energy dissipating plates are trapezoidal with the longer parallel side tangential to the wall of the tank.

A cryogenic liquid tank (1) includes a reservoir (5) that includes a bottom portion (5a, 5a1, or 5a2) and a side wall (5b), a support portion (4) that supports the reservoir (5), and an intermediate member (10) that is provided between the reservoir (5) and the support portion (4). The support portion (4) includes an outer support portion (4b) which supports the side wall (5b), and an inner support portion (4a) which is disposed to be adjacent to an inner side of the outer support portion (4b), includes a heat insulating layer formed of an elastic material, and supports the bottom portion (5a, 5a1, or 5a2) of the reservoir (5). A cover portion (9a, 9a1, or 15) covering a boundary between the outer support portion (4b) and the inner support portion (4a) is provided between the support portion (4) and the intermediate member (10).

A sealing system for a covered tank, particularly a fixed gas-sealing tank in a wastewater treatment system, includes a thrust ring positioned just inside the tank rim, secured to a series of radial beams for the cover. Preferably supported on corbels anchored to the interior tank wall, the thrust ring has an outwardly extending generally horizontal flange that overlies the edge of the tank rim. To this flange and to the top of the tank rim is secured a flexible membrane seal, around the periphery of the tank. The membrane seal is easily installed, reliable as a seal, and can be efficiently replaced when needed.
