摘要:
A truss structure may include a plurality of load bearing members, or force members, that are joined at a plurality of nodes to define a load bearing structure. The truss structure may include a plurality of longitudinal members extending in parallel along a longitudinal length of the truss structure, and a plurality of transverse members, joined to the plurality of longitudinal members at nodes, and extending between the plurality of longitudinal members. The plurality of transverse members may provide buckling support to the plurality of longitudinal members, so that an axial load, or compressive load, or buckling load, may be effectively carried by the truss structure.

A key for assembling at least a portion of a stay-in-place form-work for casting a structure from concrete or other curable construction materials. The stay-in-place form-work comprises a first elongate panel comprising a first edge component and a second elongate panel comprising a second edge component. The first and second panels are connectable in an edge-to-edge relationship wherein the first and second edge components engage one another. The key comprises a plurality of connector components for slidable engagement with complementary panel connector components on at least one of the first and second panels and a locking component for forcing the first and second edge components into a locked configuration as the key is moved longitudinally relative to the first and second panels while slidably engaged thereto.

A profile is produced from a bent metal sheet surrounding an interior space by at least 360°, the longitudinal edges of said metal sheet being connected to respectively adjacent wall sections of the metal sheet. The longitudinal edges are separated from the respectively adjacent wall sections or longitudinal edges by spacers and are connected thereto in a form-fitting manner by fasteners such as screws, rivets, or the like.

A fitting for connecting first and second pieces of channel framing to one another includes a coupling component having first and second coupling portions. The first coupling portion has a dovetail cross-sectional shape, and the second coupling portion having a dovetail cross-sectional shape which is inverted relative to the first coupling portion. The first coupling portion is configured for reception in a fitting groove of the first piece of channel framing, and the second coupling portion is configured for reception in a fitting groove of the second piece of channel framing to connect the first and second pieces of channel framing to one another such that the fitting sides of the first and second pieces of channel framing are juxtaposed and face one another.

A set of profiles for forming complex profiles comprises two profiles, namely a first profile (10) and a second profile (20), adjoining each other and having walls surrounding a main chamber. Each profile (10, 20) of the set has an outer shape which may be inscribed into a triangle, and has an inner wall (12, 22) with a faying face (13, 23) without protruding fragments. The faying faces (13, 23) adjoining each other, after being coated with adhesive enable a joint to be created when the complex profile is discussed, however, in the case of the set of the profiles they are considered to be contact surfaces. After adjoining the first profile (10) and the second profile (20) by attaching the first faying face (13) to the second faying face (23) in order to create a complex profile (30), a first outer surface (15) of first side walls (14) and a second outer surface (25) of second side walls (24) are situated outside of the complex profile and an angle between the first outer surface (15) and the second outer surface (25) equals to a sum of a first angle (α) between the first faying face (13) and the first outer surface (15) of the first side wall (14) of the first profile (10) and a second angle (β) between the second faying face (23) and the second outer surface (25) of the second side wall (24) of the second profile (20).
摘要:
Multifunctional modular mother-beam built in structural steel or similar light, sturdy material, with a “U” configuration and provided with holes along its entire length, either on the back side, on the flanks, or on the edges, by which said mother-beams connect to one another either through their back sides, their flanks, or their edges, at any angle. They are fastened with screws inserted into said holes, with no need for welding. The flanks and edges are bended to facilitate fitting and fastening of the mother-beams. Mother-beams may connect by overlapping their back sides, by joining their edges, by joining their flanks, by joining flanks with edges, edges or flanks with the back side, through direct or reversed connection. It can act as a beam, pillar, trussed beam or bar, being especially useful in the construction of large areas, such as pavilions or similar constructions.
摘要:
A modular structural load bearing device including light-weight composite structural members each including an elongated body having at least one internal recess for a cable in the recess or series of recesses. Preassembled and presized composite support members and connectors can form a modular structure, such as a crane. When used, end pieces or other components on an end of the elongated body can secure a cable. For assembly of the structural load bearing apparatus, connectors can be used with composite structural members that are light-weight with relatively thin walls while providing enhanced benefits for resisting the combination of tension, compression and buckling forces.
摘要:
A method for fabricating a hollow bar that forms elements of a grille or railing of a metalwork piece where the bar is twisted manually, machine-assisted or automated machinery, into a spiral form for decorative or ornamental purposes. By providing the hollow bar to be comprised of separate longitudinal parts which may be hinged-joined to complementarily fastened to each other to form the hollow bar, the longitudinal joints are thus amenable to increased torsional stress, such that each of the parts may be twisted without breaching the material's fatigue limit and the bar as a whole capable of being twisted with more spiral turns within its elasticity limits. The twisted bar may thus be released for re-working for adjustments or re-installation. A number of exemplary joint embodiments, internal and external bracing accessories are also disclosed to cater for the different longitudinal part fabrication, e.g. by extrusion or roll-milling.
