Abstract: There is a module for vertical farming. Vertical posts form a grid having rows in both the longitudinal direction and transverse direction. Diagonal support members are installed between posts in a longitudinal direction, along two opposed inner sides of the module, one being along a corridor for passage. In the transverse direction, other diagonal support members are installed without blocking the corridor, and racks are formed in said direction comprising the other diagonal support members, the racks extending vertically for growing plants therein along a height thereof. Floor anchors and corresponding ceiling anchors, located respectively at the bottom and at the top of each one of the posts, are provided to fasten modules on top of each other such that the structure formed by the posts is the load-bearing structure. Catwalks are installed for human passage in the corridor and between adjacent racks.

Abstract: A locking nut comprising at least two nut portions and at least one frangible bridging portion and a method of making a locking nut. The nut portions are made from a single nut. Each nut portion has an outer gripping surface and a centrally disposed threaded aperture for receiving and engaging a screw. The bridging portion is integral with the nut portions and is disposed to a side of the aperture adjacent to the gripping surface. The nut portions are disposed on either side of the bridging portion so that the apertures are axially aligned, the threads are aligned and a space is defined between opposing faces of the nut portions. By applying torque to one of the nut portions relative to the other nut portion, the bridging portion is sheared and opposing faces of the nut portions are brought into contact and the nut portions are locked in place.
