ABSTRACT:
A rod connection arrangement includes a connection element for connecting a cylindrical reinforcing rod to a cylindrical main rod, with the reinforcing rod extending at an angle to the axis of the main rods. Each rod respectively consists of a core of compression material surrounded by a fiber composite wall having fabric layers with fibers that cross at an angle. The connection element consists of an arcuate body having a central axis and an inner surface with a radius substantially equal to an outer radius of the main rod. The arcuate body preferably extends over an arc of less than 360 degrees. The connection element further consists of an integrally formed joint plate projecting radially outwardly from an outer surface of the arcuate body. The joint plate is preferably formed by two layers of a fabric material imbedded in a rein matrix wherein fibers of the fabric layers cross at an angle of substantially .+-.45 degrees. The fabric layers extend from the joint plate onto the arcuate body to form the outer surface thereof. The inner surface of the arcuate body is secured with an adhesive to the outer surface of the main rod. The reinforcing rod further includes a compression resistant reinforcement inserted into one end thereof and further has an axially symmetrical slit formed in the end thereof, the slit being received over the joint. The slit end of the reinforcing rod is secured to the joint plate with an adhesive.
