A beam clamp, including a clamp body having a rectangular shape symmetrically bent and butt-jointed by a plate material is described. On one side of the body housing a butt seam is a butt-joint face, and clamping jaws are protruded on the two sides of the body at the two sides of the butt-joint face. A clamping plate face is convexly disposed on one side of the body opposite the butt-joint face, and a screw hole corresponding to the clamping jaw is bored on the plate face. The screw hole is tapped and a bolt is disposed therein. The bolt and jaws form three-point clamping, providing high fastening performance. Corresponding threaded rod holes are bored on the plate face and butt-joint face and tapped. The resulting clamp has high processing precision, efficiency, and adaptability; the structure strength is high; load performance is good; and the size is small.
