Angled coupling including main pass-through coupler to allow first threaded rod to pass therethrough and second coupling extending at angle therefrom to receive second threaded rod. Angled coupling can be used for multiple purposes including, but not limited to, adjusting location of threaded rod, seismic restraints, storm surge restraints and/or providing additional mounting points for support members. Main coupler is configured to be secured to any location on first threaded rod without requiring it to be screwed onto first threaded rod. Main coupler may include first half and second half each traversing length thereof, that can be secured together at desired location on first threaded rod. Main coupler may include upper section having first approximately half of body thereof and corresponding threads and lower section having second approximately half of body (opposite first half) and corresponding threads. Angled coupling is made of high strength material (e.g., steel, cast iron, composites).

An assembly for integrating an elongate structural member is provided. The elongate structural member includes a first end portion, a second end portion, and an elongate mid-portion that extends between the first and the second end portions. The first end portion is within a first plane and the second end portion within a second plane, and the first and the second planes are offset and parallel to each other. The elongate mid-portion is sloped between the first and the second planes. each of the first and the second end portions defining therein a polygonal hole. Multiple elongate structural members may be used to assemble a lattice structure.

A sandwich structure includes two face plates, with a lattice structure between the plates, and with hard points at selected locations. The face plates, and the lattice structure with its hard points, may all be made as a single continuous piece by an additive manufacturing process. The hard points may be strengthened and/or stiffened areas of the lattice that may be used for connecting fasteners, or for other purposes. The hard points may be located at the junction between the lattice and one of the faces, and may be a locally thickened portion on one of the faces, for example being a cylindrical or parallelepiped protrusion out from the face. The hard points may serve the purpose of a built-in nut plate, such as themselves containing threaded holes, or by having a threaded inserts put into holes or recesses in the hard points.

A large-angle sloping roof steel structure connected to a main body structure, including: an intermediate platform, inclined main supporting steel columns circumferentially connected at four corners of the intermediate platform, constructing steel columns and wind-proof surrounding beam connected between top ends of the inclined main supporting steel columns, where roof purlin are connected between the adjacent inclined main supporting steel columns at intervals. The invention provides a top-down inverted construction method for a large-angle sloping roof with a steel structure as the main structural form. By using the method, the operation safety of an inclined main stressed vertical member during the installation process can be ensured, and the investment of supporting measures is reduced by preferentially installing the intermediate platform, thus effectively ensuring the installation progress, quality and safety of the sloping roof steel structure. The present invention can be widely applied to sloping roof construction.

An angled coupling to receive multiple pieces of threaded rod in order to adjust the location of the threaded rod, that can also be used for seismic restraints and/or storm surge restraints. The angled coupling includes a first internally threaded coupler and a second internally threaded coupler connected to the first coupler and extending from the first coupler at a defined angle from an axis thereof. The angled coupling may include additional couplings extending from the first coupler at the defined angle that may be spaced apart around the axis of the first coupling. The first coupler may be a passthrough coupler to either have a threaded rod pass therethrough or to receive a first threaded rod in a first side and a second threaded rod in a second side. The angled coupling is made of a high strength material (e.g., steel, cast iron, composites, high strength plastics, combinations thereof).

A storage system includes a storage grid structure and multiple remotely operated storage bin handling vehicles. The storage grid structure includes a first and a second type of vertical storage column profiles defining multiple storage columns in which storage bins can be stored one on top of another in vertical stacks. The storage column profiles are interconnected at their top ends by rails forming a horizontal rail grid upon which the bin handling vehicles may move in two perpendicular directions. The first type of storage column profiles has a cross-section comprising a hollow centre section and four corner sections. Each corner section includes two perpendicular bin guiding plates for accommodating a corner of a storage bin. The second type of storage column profiles has a cross-section comprising a hollow centre section having at least two connecting elements, and at least one corner section. The corner section includes two perpendicular bin guiding plates for accommodating a corner of a storage bin. The storage grid structure includes a grid supporting structure including at least some of the second type of storage column profiles interconnected, via their connecting elements by vertically inclined support struts.

A multiple rod linkage structure includes at least a first rod piece and a second rod piece which are muff-coupled. The first rod piece having a rod opening end sleeved within the second rod piece, and a rod strip opening being opened on a sidewall of the rod opening end. A locking element is connected between the first rod piece and the second rod piece, movably passes through a sidewall of the second rod piece and a sidewall of the first rod piece from outside to inside, is screw-thread fitted with a sidewall of the first rod piece, and then presses against another sidewall of the first rod piece. A tent uses the multiple rod linkage structure as a beam and/or a top rod.
