Embodiment Construction

[0060] in figure 1 Shown therein is a reinforcing strip indicated generally at 10, which has a first section 11 extending along most of the length of the strip and a second section 12 extending a part of the length of the strip. The strip is usually formed in a continuous configuration, so that the first and second segments are alternately repeated. The length of the second section will generally include only a short portion relative to the length of the main section 1, so that, for example, the main section may be 12 feet long and the second section only 6 inches long.

[0061] The reinforcing strip is separately formed of the resin material 14 which penetrates into the section including the longitudinal reinforcing fibers 15 and the reinforcing fibers around which the reinforcing fibers 16 and 17 are wound.

[0062] Longitudinal reinforcing fibers 15 constitute the main volume of the structure, so that the fiber content can typically be composed of 90 to 97% of longitudinal fiber...

Abstract

A composite reinforcing bar is formed from a series of inner rovings with first and second helical wrappings of at least one roving wrapped around the inner rovings in opposed directions of wrapping with the resin permeated therethrough. The bar structure is formed to allow torsional bending sufficient to allow the formed bar to be wound to form a coil of the bar wrapped a series of times around an axis at right angles to the length of the bar. The bar is forwarded into a rotating winding frame formed by a series of posts around a vertical rotation axis. The coil is held in place while the frame is removed for transporting the coil to a remote location. At the remote location the coil is placed in a similar winding frame and the bar is pulled from the coil and cut to a required length.

Description

Technical field [0001] The invention relates to a method for the manufacture of fiber-reinforced reinforcing strips or "reinforcing ribs". [0002] The term "reinforcing rib" as used herein is intended to include hollow bars and rods, i.e. pipes. The outer surface is preferably but not necessarily circular in cross section. The rods can be any length, including relatively short elements, making them sometimes called "bolts." Background technique [0003] The use of fiber reinforced plastic (FRP) poles in construction, marine, mining, and other industries has been increasing. This is because FRP has many benefits, such as not being corroded (chemical or salt water), non-metallic (or non-magnetic) and non-conductive, about 2 to 3 times the tensile strength and 1 / 4 weight of steel reinforcement rods, and steel The rod has a thermal expansion coefficient that is more compatible with concrete or rock. Most strips are often produced by a pultrusion process and have a linear or unifor...
