Abstract
Method and apparatus for producing an advanced fibrous composite, concrete-reinforcing bar device by laying down a continuous band of tow or tows, yarn or yarns, or strand or strands of very fine filaments and liquid bonding material along at least an elongate, removable, form piece as a band member of endless belt formation through a delivery eye that reciprocates longitudinally along such form piece, which form piece is removed after setting of the bonding material to provide an empty space between a pair of load-bearing tandem portions of such band member.
Claims11
An advanced fibrous composite, concrete reinforcing bar device of high strength, high modulus, fibrous laminate material having a multitude of very fine structural filament bonded together as laminae, comprising fid members spaced apart longitudinally at opposite ends of an elongate, three-dimensional space;
- said fid members being of longitudinal, outwardly extending, substantially conical formation;
- and a pair of endless belt band members, each having elongate, substantially entirely mutually spaced tendons extending longitudinally at opposite sides, respectively, of said three-dimensional space, with canted ends interconnected with said tendons and extending along and transversely around said fid members, respectively, forming a three-dimensional, shell shape as a concrete reinforcing bar device.
A concrete structure reinforced by the combination therewith in a strengthening manner of at least one reinforcing bar device having at least one elongate band of endless loop formation with opposite loop end portions and providing, between said loop end portions, a pair of substantially entirely mutually spaced, elongate, longitudinal members as load-bearing tendons with which said end portions are connected, said band being made of fibrous material having a multitude of structural filaments bound together by a set bonding material.
A method of producing an advanced fibrous composite, concrete reinforcing bar device of high strength, high modulus, fibrous laminate material having a multitude of very fine structural filaments bonded together as laminae by feeding a continuous length of said fibrous material, including a settable, liquid, bonding material, into and through delivery means having a delivery eye mounted for traveling along an elongates removable form piece disposed between fid members of substantially conical formation at opposite ends, respectively, of said form piece;
- reciprocating said delivery eye longitudinally along opposite sides of said form piece and transversely along and canting around said fid pieces, from one side to the opposite side of said form pieces, to lay down substantially entirely mutually spaced, elongate tendons and canted end portions of endless belt band members, respectively, that are interconnected with said tendons, to form a three-dimensional, shell shape as a concrete reinforcing bar device;
- and removing said form piece to provide elongate, three-dimensional space between said tendons and said end portions of the respective band members.
A method of producing a reinforced concrete structure, comprising making an advanced fibrous composite, concrete reinforcing bar device of high strength, high modulus, fibrous laminate material having a multitude of very fine structural filaments as laminae by feeding a continuous length of said fibrous material, including a settable liquid bonding material, into and through reciprocating delivery means having a delivery eye traveling along form means, that has at least a removable, elongate, center form piece, to lay down an elongate band member with substantially entirely mutually spaced, longitudinal, load-bearing tendons and continuous loop end portions interconnected with said tendons;
- removing said center form piece after the bonding material has set to leave an empty space between said tendons;
- and incorporating the resulting concrete reinforcing bar device in a concrete structure as a concrete reinforcing member.
