The invention relates to a coupling for connecting construction parts, a truss provided therewith and associated meth od and use. The coupling comprises a female and a male coupling part. The female coupling part comprises: a tubular receiving part, the wall of which an opening is provided; a ball which is placed in the opening and which is movable in radial direction of the receiving part; and a locking sleeve which is screwed onto and encloses the receiving part and which by being screwed is movable in the longitudinal direction of the receiving part between an opened position, in which the locking sleeve allows movement of the ball in the opening for the purpose of placing/removing the male coupling part into/from the receiving part, and a closed position in which the locking sleeve locks the male coupling part in the female coupling part with the ball, wherein the male coupling part is an elongate pin which comprises in its outer wall a groove for the ball.

A modular structure system of detachable members, the system includes a support pillar and various connectors. The support pillar has a main body and a plurality of channel walls outwardly radiating from an outside surface of the main body. The channel walls are disposed lengthwise on the main body from one terminal end of the main body to another terminal end of the main body. The support pillar has a symmetrical cross-sectional shape and each of the channel walls has an expanded distal end forming two lips.

The disclosure is directed to an elongated geodesic dome with an arched-tunnel section. In some embodiments including: a first adjustable angle hub connector, the first adjustable angle hub connector being a connector of a first plurality of tubular struts, the first plurality of tubular struts being inserted into the first adjustable angle hub connector; a second adjustable angle hub connector, the second adjustable angle hub connector being a connector of a second plurality of tubular struts, the second plurality of tubular struts being inserted into the second adjustable angle hub connector; a third adjustable angle hub connector, the third adjustable angle hub connector being a connector of a third plurality of tubular struts, the third plurality of tubular struts being inserted into the third adjustable angle hub connector. The adjustable angle hub connectors may be removable for adjusting a length of the arched-tunnel section of the elongated geodesic dome.

The invention of the present disclosure may be a temporary structure comprising a plurality of conduits, each conduit comprising a lumen and a standard length; a plurality of connectors, each of the plurality of connectors comprising at least one attachment member, wherein each of the at least one attachment members is configured to reversibly attach to at least one of the plurality of conduits, and wherein each of the lumens is sized to accept at least one attachment member; and a plurality of panels, wherein each of the plurality of panels is configured to reversibly attach to at least two of the plurality of conduits.

An installation system for partition panels in a room, the system including at least one upper telescopic group, having sections and constrained to the ceiling, and at least one lower telescopic group, having sections and constrained to the floor, a series of partition panels positioned between the upper and lower telescopic groups with coupling-uncoupling groups, where both the upper telescopic group and lower telescopic group comprise a first section and a second section for coupling with each other, the second section slidingly arranged inside the first section and adjustable with respect thereto, each of the coupling-uncoupling groups comprising a first female coupling element and a second male coupling element, one connected to the second section and the other to the partition panel, which can be engaged with each other by a releasable constraint.

A combined member, comprising a communication rod (1) and a connecting rod (2), wherein the connecting rod (2) comprises a rod body (2.1) and a connector (2.2), the connector (2.2) being a fastening connector (3) or a sleeving connector (4), the rod body (2.1) of the connecting rod (2.1) and a rod body of the communication rod (1) being of a strip-shaped structure, the connecting rod (2) being connected to the communication rod (1) by the fastening connector (3) or the sleeving connector (4), the axis of the connecting rod (2) intersecting that of the communication rod (1) connected thereto. The combined member has the advantages of high bearing capacity, and convenient construction.

A building system comprising a plurality of tubes, a plurality of connection nodes comprising tubular sections for connection to the tubes, wherein the tubes are arranged to connect between the connection nodes to form a frame for a building, wherein at least one continuous cavity is formed through at least a portion of the nodes and tubes when the nodes and tubes are connected, the building system further comprising fluid tight seals between the tubes and connection nodes to enable fluid to flow through the at least one continuous cavity.

A self-bracing, two-way moment frame precast system for industrial support structure and method of erecting a precast industrial support structure without temporary or permanent bracing or shoring are disclosed. This is accomplished by utilizing a moment frame element in two directions to create free standing tower that requires no bracing during erection or in service. The system also utilizes a connection that allows the erection crane to achieve alignment during erection such that the entire system can be erected by a ground based personnel.
