Abstract:
1. A reinforcement device to enhance compression buckling strength of an angle-type steel-frame member used to construct a truss structure of a power-transmission tower, the reinforcement device comprising: a member seating body to surround the angle-type steel-frame member and restrict the movement of opposite ends of the angle-type steel-frame member, wherein the member seating body is formed with a larger angle than the angle-type steel-frame member; first and second securing couplers to secure opposite ends of the angle-type steel-frame member and opposite ends of the member seating body, respectively, wherein the first and second securing couplers are adjustable to receive the respective ends of the angle-type steel-frame member depending upon a dimension of the angle-type steel-frame member; a horizontal engaging element formed in an elongated round-bar that connects the first and second securing couplers through securing bolts provided at opposite ends of the engaging element; a supporter positioned in a space where the angle-type steel-frame member forms a right angle and supporting the angle-type steel-frame member, wherein the supporter includes an elongated member fastening bolt and a reinforcing-bar securing bolt that is shorter than the member fastening bolt; and a reinforcing bar positioned in a space formed by the angle-type steel-frame member to connect the supporter and the horizontal engaging element, wherein the elongated member fastening bolt of the supporter penetrates through the reinforcing bar to make contact with the angle-type steel-frame member.
