An L type clamp for a power transmission tower is provided to prevent the damage of a square timber surface by forming a coating unit on the inner surface of a first clamping portion and a second clamping portion. An L type clamp for a power transmission tower comprises a first and second clamping portions(11,12) and a first hinge(21). The first clamping portion is curve-cut in the form of L. A bent portion(13) is formed at the first clamping portion. The second clamping portion is formed into the same form as the first clamping portion. The inner surface of the second clamping portion is overlapped with the inner surface of the first clamping portion. The first and second clamping portions are connected each other by a first hinge. The first and the second clamping portion performs clamping with rotating around one end. A annular part(14) is formed in the other side end of the first and the second clamping portions and the outside bent portion of the first clamping portion. A coating unit(15) is formed in the inner surface of the first and the second clamping portions in which the first and the second clamping portion are contacted each other. The separated bent portion of the first clamping portion is connected by a second hinge. |
