Truss section connection apparatus
A truss connection apparatus is used to connect truss sections. A connection segment is mounted on each truss to be connected. Each connection segment has an opening, in alignment with each other to receive a fastener. The fastener is threaded on one end and can receive a nut. The other end of the fastener is a locking end having a radial protrusion. One of the connection segments has a securing means adapted to secure the locking end when the at least one protrusion of the locking end is rotated to a locking position. In the locking position the protrusion mates with the securing means and the fastener is prevented from rotational or axial movement and connection segments are fixed relative to each other as are the truss sections on which the connection sections are mounted.
1. A truss section assembly, comprising:
a truss section;
a first fastener comprising:
a threaded end for receiving a second fastener,
a shaft,
and a locking end comprising at least one protrusion extending radially from the shaft, wherein the shaft is disposed between the threaded end and the locking end;
at least one connection segment attached to an end of the truss section for connection to a corresponding connection segment on a second truss section, each of the at least one connection segments comprising:
a body having an opening dimensioned to receive the shaft and the locking end of the first fastener for joining said at least one connection segment with the corresponding connection segment of the second truss section,
wherein the opening of the at least one connection segment is dimensioned to receive therethrough the shaft and the locking end of the first fastener when the at least one protrusion is aligned with the opening, and wherein when the at least one protrusion is not aligned with the opening the locking end is prevented from passing through, whereby when the shaft of the first fastener is disposed through the opening of the at least one connection segment and disposed through an opening of the corresponding connection segment of the second truss, the locking end is secured in a locked position by engagement of the locking end with a securing means on the at least one connection segment, such that when the second fastener is tightened onto the threaded end of the first fastener, the first fastener is prevented from both rotational and axial movement.
2. The truss section assembly of claim 1 wherein the first connection segment is mounted on or integral with the truss section.
3. The truss section assembly of claim 1 wherein the at least one protrusion of the locking end of the first fastener comprises a T-shaped portion having two protrusions that extend radially from the shaft in opposite directions to an extent greater than the size of the opening of the corresponding connection segment.
4. The truss section assembly of claim 1 wherein each truss section comprises two or more connection segments.
5. The truss section assembly of claim 1 wherein the securing means comprises a slot corresponding in shape to the locking end of the first fastener.
6. The truss section assembly of claim 1 further comprising a stopper secured to the threaded end of the first fastener, wherein the stopper is wider than the inner diameter of the second fastener to prevent the second fastener from being removed from the threaded end.
7. The truss section assembly of claim 1 wherein the opening of the corresponding connection segment is dimensioned to prevent the locking end from passing through the opening of the corresponding connection segment.
8. The truss section assembly of claim 1 wherein the opening of the corresponding connection segment is equipped with a gasket, wherein the gasket abuts against the surface of the shaft of the first fastener creating resistance thereby preventing the first fastener from sliding freely within the opening of the corresponding connection segment.
9. The truss section assembly of claim 1 whereby the truss section is connected to further truss sections to form a truss structure.
10. The truss section assembly of claim 1 wherein the at least one connection segment comprises the securing means, and the securing means comprises a slot corresponding in shape to the locking end of the first fastener.
