A modular unit for forming a multiple member joint includes: an elongate body; a bracket attached adjacent an end of the elongate body, the bracket located around a longitudinal axis of the modular unit; a plurality of connectors associated with the bracket with a position retention mechanism, the plurality of connectors extending from the end of the elongate body parallel to a longitudinal axis of the modular unit; and one or more connector joints attached at a distal end of the plurality of connectors, wherein the one or more connector joints are adapted to join with one or more connector joints of connectors extending from connectors of an adjoining modular unit.

A connection apparatus may be used to connect truss sections or other objects. A connection segment is mounted on each truss to be connected. Each of a first and second connection segment has an opening, in alignment with each other to receive a fastener. The opening of the first connection segment allows the fastener to pivot. The second connection segment has a side opening which allows the fastener to pivot inside and outside the body of the second connection segment. The fastener has a threaded end and a locking end. The locking end may be secured against an outer surface of the second connection segment. In the locked position the locking end of the fastener engages the outer surface of one the second connection segment and the fastener is prevented from rotational or axial movement. The connection segments are thus fixed relative to each other as are the truss sections on which the connection sections may be mounted.

A modular connection device is provided. The modular connection device includes a base and a plurality of connection members. The base includes a plurality of connection surfaces, wherein each of the connection surfaces is connected with each other. Each of the connection members is detachably connected on each of the connection surfaces.

A spatial structure that enables the assembly and disassembly of architectural elements quickly and easily, ensuring the necessary structural robustness and which basically comprises a node (1) with a plurality of sockets (2), a bar (3) intended for insertion at either of the two ends thereof in said sockets (2), a perforated screw (5) whose inner surface (6) allows the insertion of the end of the bar (3) and whose outer surface is coupled to the sockets (2), and a portion of flexible washer (8) suitable for insertion into the socket (2) of the node (1) and closing by compression as a result of the thrust exerted by the perforated screw (5) to adopt the shape of a substantially closed washer such that said bar (3) is locked inside the perforated screw (5), preventing the disassembly of the structure but not the rotation of the bar (3) inside the socket (2).

Described herein is a System of Tubular Connections (STC) for a building method for constructing and fastening together any elongated symmetrical frameworks such as awning or fences, eliminating the need for other fastening methods such as welding. The STC consists of four (4) basic physical elements. Element 1 is any elongated symmetrical shape, for example tubing or 24 wooden boards. Element 2 is any threaded product. Element 3 is a tubing fastener used when Element 1 is symmetrical hollow tubing. Element 4 is the building block that the elongated symmetrical shape is screwed into or through.
