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 decorative moulding assembly for a wall or ceiling in an interior space. The decorative moulding assembly may include a first moulding piece and a second moulding piece each having an ornamental front surface, a rear surface, and a channel in the rear surface and a connector for connecting the first and second moulding pieces together. The connector may include a first portion that nests within the channel of the first moulding piece and a second portion that nests within the channel of the second moulding piece. The first portion of the connector may include a U-shaped body having first and second legs that deflect inwardly towards one another as the first portion of the connector is being inserted into the first channel of the first moulding piece.

An internal splice joint that facilitates coupling of a pair of joist members together is provided. The internal splice joint includes a main wall, first and second side flanges, and first and second end flanges. The first side flange extends upwardly from the main wall. The second side flange extends upwardly from the main wall and is spaced from the second side flange. The first end flange extends from the first side flange. The second end flange extends from the second side flange. The first end flange and the second end flange extend inwardly towards each other and are spaced from each another. A joist assembly that includes the internal splice joint is also provided.

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 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.

The present invention relates to connecting spacing members between support members using spacing members having notches that engage the side edges of the linear shape holes or round holes in the support members whether the holes have rims or ledges to secure the spacing members or crossing other support members having notches in the edges of the lips. The spacer braces can overlap each other and connect at the top, bottom or within the holes of support members. The support members have ledges and rims to eliminate vertical and horizontal movement of the spacer braces with end fingers to stop end the spacer braces.

A method includes forming a cutout in a bamboo pole, the cutout having a non-uniform perimeter, and in which the perimeter increases towards a region of the bamboo pole where fibers of the pole are stronger than other regions of the bamboo pole.

An arcuate mounting bracket fabrication system includes a powered roller conveyor for receiving blanks to be formed into arcuate connection brackets. A roll form assembly received the blanks and includes a plurality of roll forming dies for incrementally bending portions of blanks to form straight flanges terminating in lips. An entry assembly carried by the powered roller conveyor positions the blanks entering the roll form assembly. An arcuate flange forming apparatus for forming arcuate flanges in the roll formed blank receives roll formed blanks from a transfer mechanism.
