Abstract
The present invention provides a portable modular roof truss system. In one embodiment, a portable modular roof truss system comprises at least one roof truss device comprising a roof apex collar, a crossbar, two arms, and two connecting members. The collar comprises two separate members coupled together by at least one bolt to form an opening capable of receiving a roof pole. In another embodiment, a portable modular roof truss system comprises two roof apex collars. In yet another embodiment, a roof truss device comprises a collar, a crossbar, two arms, and two connecting members. The collar comprises two separate members coupled together by a hinge to form an opening capable of receiving a roof pole.
Claims23
A roof truss apex device, comprising:
- a roof apex collar comprising:
- a top member including a top surface that comprises a substantially convex surface;
- a bottom member;
- and
- a locking mechanism to couple the top member to the bottom member to form an opening in the collar, wherein the opening is configured for receiving a truss member;
- a first elongated arm with a proximal end coupled to the bottom member of the collar;
- and
- a second elongated arm with a proximal end coupled to the bottom member of the collar, wherein the first and second arms are transverse in relation to one another and slope downwardly away from the collar;
- wherein the device is configured for engaging two truss segments sloping downwards away from the collar;
- wherein the opening is shaped to accommodate a profile of the truss member;
- wherein the locking mechanism comprises at least one bolt that couples the top member to the bottom member of the collar to engage and maintain in place the truss member within the opening;
- wherein the top member further comprises;
- a bottom surface;
- and
- at least one countersunk hole located at a distal end of the top surface configured for receiving the bolt;
- and
- wherein the botom surface is a substantially semi-cylindrial concave surface configured for both receiving and supporting walls of the truss member.
