Provided herein is an assembly for carrying or supporting a load. The assembly comprises a plurality of members connectable in an assembled arrangement for carrying or supporting the load. Each member comprises a first end and a second end, at least one of the first end and the second end has a pair of connecting members comprising two lugs that each has defined therein two holes. The lugs are configured for alignment with a corresponding pair of lugs formed on another member in the assembly. Fasteners extend through the holes formed in the lugs when the holes are aligned. Further provided are members for use in the assembly and connector elements for attaching two or more members in the assembly.

A process, mechanical method, and mechanical utility invention that creates an expandable sustainable member beam with utility in its' substantially different shape, mobility, multi-functional capabilities, and sustainability from its' conventional counter part. It can be utilized independently, as a utility stand, in plurality, sharing a base(s) and platform(s), as a step, or in conjunction with other expandable sustainable member beams from which to build. Some embodiments may replace a conventional wood or metal 248 stud in many applications. Additional utilities include, but not limited to: a post, concrete form, assistive device for mobility challenged individuals, independent balance, self-leveling, varying angular degree manipulation, elevational deployment and retraction capabilities. It can be substantially shortened for transport and deploy to varying longitudinal values to regain its utility upon user demand. Thereafter, it can be uninstalled and used again for like or different utilities, making it largely sustainable.

A vertically adjustable steel reinforcing assembly, especially adapted for effective use with dapped beam ends. The reinforcing assembly includes an upper assembly and a lower assembly. Running vertically through the center of each of the assemblies are aligning pin holes. Assembly is configured at the time of casting to accommodate most recent dap design.

A fixture for setting rebar at a predetermined distance from the rim of an excavated pit includes elongated first and second legs each having a proximal end and a distal end, the first and second legs rigidly joined at their mutual proximal ends to form an L-shape; an angle adjustment device carried by the first leg, comprising a foot movable towards or away from the first leg along an axis generally parallel to the second leg; a support bracket carried by the first leg at a predetermined offset distance from the proximal end thereof; and a hook extending from the distal end of the second leg, generally parallel to the first leg.

A mechanical utility fastening device created as an alternative rigidity mechanism to the expandable sustainable member beam recited in the parent application U.S. Ser. No. 15/703,993; which connects two items when flexibility and movement between the two connected items is necessary. The flexible fastening key allows for connection of segments of the member beam from the parent application wherein flexibility is needed between the segments and the rigidity key for the member beam to perform the utility of curvature.

Sinusoidal shaped member units and support member units are parts that form pre-stressed assemblies having flexural properties. Sinusoidal shaped members are relaxed material members that have been elastically deformed. Support members maintain the elastically deformed state of the sinusoidal shaped members. The sinusoidal shaped members and support members are organized into pre-stressed curvilinear assemblies containing stored elastic potential energy that is equal to the work done by the forces that deformed their pre-stressed structure. The assemblies' sinusoidal shaped members and support members are adapted to use materials having exceptional mechanical properties and flexural strength. This includes nano-composites and/or shape memory alloys. The assemblies' pre-stressed state enhances its mechanical, electrical and structural performance. The size, number, density and possible geometric configurations of the sinusoidal shaped member units and support member units within an assembly/structure is vast. Products of this sinusoidal building system have mechanical and structural applications and can be manufactured and/or deployed.
