A building assembly structure comprises a coupling block fixed on the ground or to a frame so as to fix and extend the frame. The coupling block comprises a body has a first through-hole passing through upper and lower portions thereof, a connection member coupled to a lower portion of the first through-hole, and having a second through-hole formed therein, a fixing plate coupled to the connection member so as to be located on the lower portion of the body, and having a fixing protrusion protruding from a side thereof, and a vibration-proof pad coupled to the upper portion of the body in order to absorb load and shocks applied from above.

A stacking ring for a chair base may be disposable between a first and second chair base such that the stacking ring generally prevents lateral movement of the first chair base relative to the second chair base. The stacking ring may be integrally formed to the chair base, or separate and disposable between at least two chair bases. The stacking ring may substantially prevent rotation of a first chair base relative to a second chair base.

Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

The invention relates to a connecting element for connecting two aligned C-shaped profile rails (12). The connecting in element (10) is in the form of a sheet metal profile the cross-section of which, adapted to the profile rails (12) to be connected, is such that said sheet-metal profile can be slid into said profile rails (12) from the fronts thereof in a captive manner. A handling tab (14) that is accessible after the connecting element has been slid into a profile rail (12) is moulded onto or mounted on said connecting element.

A system and process for removably and replaceably coupling two hollow carbon fiber composite structures without the need for adhesives or welding. A universal coupling makes use of reciprocating catches in the end regions of the universal coupling. The reciprocating catches engage receiving features provided in the hollow carbon fiber composite structures to couple the hollow carbon fiber composite structures to the universal coupling, and through the universal coupling, couple the hollow carbon fiber composite structures together. The hollow carbon fiber composite structures can be uncoupled by disengaging the reciprocating catches of the universal coupling from the receiving features of the hollow carbon fiber composite structures.

Couplers for a cable trough system including a terminal end sized to receive a terminal end of a trough member along a longitudinal direction of the body. A spring may be coupled to the body for securing the terminal end of the trough member to the coupler, the spring including first and second spring arms extending generally in opposition to one another in a plane generally parallel to the longitudinal direction. The spring may be received in a slot formed by the trough member. Also included may be a spring release mechanism coupled to the body, the spring release mechanism sliding in the longitudinal direction between a locked position, such that the first and second spring arms engage the terminal end of the trough, and an unlocked position, such that the first and second fingers release the first and second arms of the spring.

A pile connecting metal bracket adapted to be secured to a structure to be supported by a metal pile is described. The bracket has a pair of elongated straight vertical support flanges in a pair of spaced-apart horizontal guide walls secured across the vertical support flanges. The guide wall guides driven hollow metal tubes of the pile. A drive mechanism is removably connected to an attachment. The pile connecting bracket is secured to a structure and the metal tubes of the pile are connected to the metal bracket after the metal pile has been driven into soil to a position of rest whereby the pile can support the structure.
