Abstract: A method for producing a reinforcement rod from a fibrous composite material comprising continuous mineral fibers and at least one resin, the resin being mixed with the dry mineral fibers, then wrapped with a strand of material, and the resin then being instantaneous or nearly instantaneously cured (e.g., snap cured) to form an optionally round rod with an optionally helical rib. In aspects, a mixture comprising an environmentally friendly and zero or low volatile organic compound (VOC) emitting resin and a resin-curing agent mixture is used. In aspects, helical ribs are added to the surface of the rod in a manner not to disrupt the longitudinal orientation of the core reinforcing mineral fibers. In aspects, ultraviolet irradiators are used to snap cure the reinforcement. When cured, corrosion resistant mineral fibers are encapsulated in a corrosion resistant matrix. The process allows for a simplified, condensed, and single operation for producing a corrosion resistant fibrous composite reinforcement rod.
Abstract: A method of making a pultruded deck board attachment fastened to a substructure to provide a stiffer and stronger deck board than a wood, wood composite, or plastic deck board, wherein the pultruded deck board attachment, along with any fasteners, is covered and protected with a walking surface that is, in examples, snapped in to place.

Abstract: A connector secures together a first member and a second member, wherein each of the first and second members of has an aperture and a wall thickness at the point ofjoining. The connector includes a body portion having a generally circular cross-section taken along a plane that is perpendicular to a longitudinal axis of the body portion. The connector is secured to the first member in the aperture by an attachment being rigidly joined to the body portion.

Abstract: An end cap for a drainage system comprises a wall element having substantially the same profile as the cross-section of the end of the trench drain channel section. The wall element is adapted to be coupled to the trench drain channel section to form a terminal end of the channel section. At least one transverse groove is provided in the channel section so that, when the end cap is separated at the groove, the height of the end cap corresponds to the depth of the channel section. Typically, a plurality of transverse grooves are provided at spaced intervals along the vertical height of the wall element which correspond to different possible depths of the channel section. Thus, the end cap may be adapted to fit any one of a number of channel sections, regardless of depth. The end cap may further comprise a pipe coupler integrally molded with the wall element such that the wall element and coupler are substantially continuous.
