Connection apparatus and method
A connection apparatus for attaching a first truss to a second truss has first and second connection segments, a bolt and an optional spring. The first connection segment has an aperture dimensioned to receive a threaded end and shank of the bolt. The aperture is also dimensioned to prevent the head end of the bolt and the threaded end from passing through. The aperture comprising a recess for receiving the second end of the spring. The first connection segment has a side opening, open to the aperture, dimensioned to receive the shank of the bolt. The first connection segment has a shoulder portion within the aperture dimensioned to closely fit around the shank and prevent the threaded end of the bolt from passing therethrough. The second connection segment for attaching to the second truss has a threaded hole dimensioned to fixably receive the threaded end of the bolt.
1. A connection apparatus to attach a first object having a first back surface and a first attachment surface to a second object having a second back surface and a second attachment surface, the connection apparatus comprising:
a first connection segment to mount on the first back surface, wherein the first connection segment includes an aperture;
a second connection segment to mount on the second back surface; and
a fastener retained by the aperture of the first connection segment, wherein the fastener is to engage the second connection segment to mate the first attachment surface with the second attachment surface,
wherein the fastener is a bolt, the bolt including a head, a threaded end, and a shank between the head and the threaded end, and
wherein the aperture is dimensioned to be larger than the shank and smaller than the head and the threaded end.
2. The connection apparatus of claim 1 , wherein the second connection segment includes a threaded hole to receive the threaded end of the bolt.
3. The connection apparatus of claim 2 , further comprising a spring disposed between the head of the bolt and the first connection segment to urge the bolt away from the second connection segment to reduce rattling when the fastener is disengaged from the second connection segment.
4. The connection apparatus of claim 1 , wherein the second connection segment comprises a recess to receive a nut, wherein the nut is to be retained between the second connection segment and the second back surface.
5. The connection apparatus of claim 4 , wherein the recess dimensioned to prevent rotation of the nut.
6. A truss section comprising:
a first attachment plate disposed at a first end of the truss section, the first attachment plate having a first back surface and a first attachment surface, wherein the first attachment surface is to attach to an external attachment plate;
a first connection segment mounted on the first back surface, wherein the first connection segment includes an aperture; and
a truss fastener retained by the aperture of the first connection segment, wherein the truss fastener is to engage the external attachment plate to attach the first attachment plate to the external attachment plate,
wherein the truss fastener is a bolt, the bolt including a head, a threaded end, and a shank between the head and the threaded end, and
wherein the aperture is dimensioned to be larger than the shank and smaller than the head and the threaded end.
7. The truss section of claim 6 , further comprising a second attachment plate disposed at a second end of the truss section, the second end opposite the first end, the second attachment plate having a second back surface and a second attachment surface to attach to an additional attachment plate, wherein the second attachment plate is structurally identical to the external attachment plate.
8. The truss section of claim 7 , further comprising a second connection segment mounted on the second back surface, wherein the second connection segment is to engage with a fastener retained by the additional attachment plate to mate the second attachment plate with the additional attachment plate.
9. The truss section of claim 8 , wherein the second connection segment includes a threaded hole to receive the threaded end of the bolt.
10. The truss section of claim 9 , further comprising a spring disposed between the head of the bolt and the first connection segment to reduce rattling when the fastener is disengaged from the external attachment plate.
11. The truss section of claim 10 , wherein the second connection segment comprises a recess to receive a nut, wherein the nut is to be retained between the second connection segment and the second attachment plate.
12. The truss section of claim 11 , wherein the recess dimensioned to prevent rotation of the nut.
