A tubular structural profile and construction system, produced by cutting and folding a semi-rigid and foldable sheet, having four orthogonal layers joined at fold lines and two internal diagonal layers joining two opposing fold lines. The sheet has six rectangular sections. The cutting lines are positioned for at least one tongue, which coincides with at least one slot located on an opposing fold lines, such that, during the folding, the profile is closed by means of the coming together of fold lines and both internal diagonal layers, and by means of the insertion of at least one tongue on its corresponding slot, and wherein, in addition, the profile of the formed system can have at least one break in the second external layers and in the two internal diagonal layers, which permit the creation of an angaging area for transverse structural profiles.

A member-to-member planar connection bracket that includes multiple repeated fuse element configurations that each provide a pre-determined inelastic load-carrying capacity and a reliable inelastic deformation capacity upon development of one or more inelastic hinge locations within the fuse elements. The fuse configurations are interconnected in series such that the total deformation accommodated between first end of the bracket and second end of the bracket is the sum of deformations accommodated by the individual fuse configurations. Multiple brackets are configured in laminar configurations and interconnected to create a connection assembly that provides increased strength or increased deformation capacity as compared to an individual bracket. The connection assembly is used to connect a first structural member and second structural member. The pre-determined maximum inelastic load-carrying capacity of the assembly is less than the elastic load-carrying capacity of the first structural member and the second structural member.

A reversible structural component for use as a portion of a vertical frame in a modular wall system includes an elongate body extending between a first end and a second end thereof, a plurality of countersunk through-holes extending through the structural component, and a plurality of threaded through-holes extending through the structural component. The countersunk through-holes and the threaded through-holes are disposed on the elongate body between the first end and the second end so that the countersunk through-holes of the structural component are aligned with the threaded through-holes of a separate identical structural component when back sides of the structural component and the separate identical structural component are brought together 180-degrees relative to one another during use.

A multifunctional design housing is disclosed. In some examples, the multifunctional design housing includes an outer case with a back wall, a first side wall, and a second side wall. The back wall includes a first back wall edge and a second back wall edge. The first side wall extends forward from the first back wall edge, and the second side wall extends forward from the second back wall edge. The front wall includes a first side wall front edge and a second side wall front edge. A front opening is formed between the first side wall front edge and the second side wall front edge providing access to an interior volume within the outer case. A conduit control arm with a support element is spaced forward from the back wall and coupled to the outer case by a spacing element.

A truss includes a plurality of truss members, each truss member formed from a unitary folded blank of sheet metal to create a main panel, and proximal and distal flanges and a horizontal panel each extending perpendicularly from the main panel, the proximal flange of a first truss member is connected to the distal flange of a second truss member to form a truss. In one embodiment employing trusses formed of folded sheet metal, a plurality of interconnected truss modules, each truss module including a plurality of truss members, forms a plurality of oppositely extending horizontal flanges that collectively present the top and bottom surfaces of a cantilevered canopy.

A truss connected to a structure via a fixed rod end attachment and at least one swing-link attachment. A first beam of the truss is connected to a frame member of the structure via a fixed rod end attachment, which locates the truss relative to the frame of the structure. Remaining beams of the truss to be connected to the frame of the structure are attached via swing-link attachments, which can pivot relative to the beam of the truss and the frame of the structure to allow relative movement between the beam and frame. The relative movement allows the structure to flex without imparting additional loads in the truss or the frame of the structure.

The invention proposes a system for constructing a module of a building, including core construction elements (1) that are surrounded by the surrounding construction elements (2A, 2B). The core construction elements (1) each include, in section, a cross including two main arms (6) of equal length which intersect at mid-length at right angle. Each core construction element (1) has a plane of symmetry about the axes of the arms. The main arms (6) of the cross terminate, at the ends thereof, with transverse portions (7). Each surrounding construction element (2A, 2B) is composed of four partial surrounding parts (2A, 2B, 2A′, 2B′) of a generally triangular shape which are assembled around a core element (1). Construction elements forming junction parts (4A, 4B) allow assembling panels (4A, 4B) to form a module of a building in the form of a rectangular parallelepiped volume comprising four corners.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

The present technology relates to beams having a cross section defining a plurality of channels and assemblies comprising the beams. The beams can be used to form a beam assembly that is installed inside the truck bed of a pick-up truck. A ladder loader and a solar panel assembly can be pivotably secured to the beam assembly along either the driver side wall or the passenger side wall of the truck bed.
