The present invention is in the field of modular structures, assembled by way of fastening or attached means, whose purpose is to be used as base support structures for various applications, particularly connecting systems involving plastic or aluminum containers, recipients, bottles or vessels. Particularly, the invention comprises an omnidirectional construction system that includes connectors and terminals to be attached to containers with threaded openings or flat openings and container bases, to which various types of connectors may be attached to.

An inter-element joint structure including: a first member provided with a hole or a trench; a second member provided with a through-hole; a bushing member fitted to the through-hole formed in the second member and fixed to the second member while the bushing member comes into contact with a surface of the first member; a fastening member including a bolt provided with a shank penetrating at least the bushing member and the hole or the trench of the first member to fasten the bushing member and the first member; and a washer that is interposed between a head of the bolt and the bushing member and has a diameter larger than that of the bushing member. The bushing member has a thickness larger than that of the second member, and the through-hole of the second member has a circumferential edge loosely fitted between the washer and the first member.

A device for strengthening and/or rigging trusses includes at least two connecting elements, which connect at least two parallel truss pipes of the truss. On these connecting elements an attachment unit provided between at least one pair of truss pipes, to which mounting structures can be attached.

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 sandwich structure includes two face plates, with a lattice structure between the plates, and with hard points at selected locations. The face plates, and the lattice structure with its hard points, may all be made as a single continuous piece by an additive manufacturing process. The hard points may be strengthened and/or stiffened areas of the lattice that may be used for connecting fasteners, or for other purposes. The hard points may be located at the junction between the lattice and one of the faces, and may be a locally thickened portion on one of the faces, for example being a cylindrical or parallelepiped protrusion out from the face. The hard points may serve the purpose of a built-in nut plate, such as themselves containing threaded holes, or by having a threaded inserts put into holes or recesses in the hard points.

A lattice structure comprising a series of connecting rings or half-rings on which a series of orienting elements are secured. The orienting elements being equipped with holes and a slot in which the connecting rings or half-rings are disposed, as well as comprising profiles that are solidly connected using joining elements that extend through holes in the profiles.

A support-framework (1) supports a surface (2), or supported elements, at a designed variable spacing from a support surface (3), using elongate supports (4) of rod-from or tubular-form that act as ties or struts. Each support (4) is anchored at one of its ends to the supported surface (2) or element and, at the other end, to the support surface (3). The anchoring at each end is via a node N that involves an individual domed-member (5) which is secured to the relevant surface (2, 3) or supported element, and which has a part-spherical surface (6) to which the elongate supports (4) are anchored to extend radially by a coupling (12). The domed-members (5) are metallic or plastics, and may each be hemispherical having an outwardly directed equatorial flange (7) by which they are secured to the relevant surface (2, 3) or supported element.
