Arm connection for a structural member
View Patent ↗A structural member and method with an improved arm connection is provided that allows quick connection of an arm to the structural member. Bolts are inserted through aligned apertures in first and second thru-vangs, as well as an abutting arm bracket. A securement member is inserted through an aperture in the bolts that is transverse to the bolts. Last, an arm is secured to the arm bracket for support of electrical conductors strung thereon.
1. A structural member including an arm connection comprising:
a first thru-vang having a plurality of apertures disposed therein, the first thru-vang secured to the structural member;
a second thru-vang adjacent the first thru-vang and having a plurality of apertures therein, the second thru-vang secured to the structural member;
an arm bracket having a plurality of bracket apertures disposed therein and adjacent to the first thru-vang and the second thru-vang such that the bracket apertures align with apertures the first thru-vang and the second thru-vang;
a plurality of elongate bolts being received through the apertures in the first thru-vang and the second thru-vang apertures and the bracket apertures, each said bolt having a head at one end and a securement aperture at the other end, said securement apertures being aligned; and
an elongate securement member inserted mutually through the aligned securement apertures of the plurality of bolts to prevent loosening of the plurality of bolts.
2. The structural member of claim 1 wherein the securement member is disposed transversally to the plurality of bolts when inserted through the securement apertures of the plurality of bolts.
3. The structural member of claim 1 wherein the securement member is releasably secured to the plurality of bolts.
4. The structural member of claim 1 wherein the securement member is a bolt that is threaded on at least one end for receiving a nut thereon.
5. The structural member of claim 1 wherein the securement member is a rod with an angled end to prevent the rod from sliding downward.
6. The structural member of claim 1 wherein the securement member is a rod having an aperture disposed therein.
7. A method for installing an arm connection on a structural member including a first thru-vang having a plurality of apertures disposed therein, the first thru-vang secured to the structural member, a second thru-vang adjacent the first thru-vang and having a plurality of apertures therein, the second thru-vang secured to the structural member, an arm bracket having a plurality of bracket apertures disposed therein and adjacent to the first thru-vang and the second thru-vang, the method comprising the steps of:
aligning the bracket apertures align with apertures the first thru-vang and the second thru-vang;
inserting a plurality of elongate bolts through the aligned first thru-vang and second thru-vang apertures and the bracket apertures, each said bolt having a head at one end and a securement aperture at the other end, said securement apertures being aligned; and
inserting an elongate securement member mutually through the aligned securement apertures of the plurality of bolts to prevent loosening of the plurality of bolts.
8. The method of claim 7 wherein the securement member is disposed transversally to the plurality of bolts when inserted through the securement apertures of the plurality of bolts.
9. The method of claim 7 wherein the securement member is releasably secured to the plurality of bolts.
10. The method of claim 7 wherein the securement member is a bolt that is threaded on at least one end for receiving a nut thereon.
11. The method of claim 7 wherein the securement member is a rod with an angled end to prevent the rod from sliding downward.
12. The method of claim 7 wherein the securement member is a rod having an aperture disposed therein.
