<p>The present invention relates to a clamp formed by joining first coupling unit (15) and a second coupling unit (16) by fixing fixed surfaces (17, 18) of the first and second coupling units facing each other. The first and second coupling units are composed of a base member (12) having the inner circumference (11) with one open side, wherein posts are received to connect and fix the posts consisting of a scaffold, to join the first and second coupling units after adjusting an angle of joining the first and second coupling units arbitrarily as occasion demands, a coupling member (14) axially joined to one end of the base member (12) to be able to rotate and having an inner surface (13) wherein the posts are received by being connected to the inner circumference (11) of the base member (12), and a fixing means capable of maintaining the coupled state of the posts by connecting and fixing the longitudinal ends of the base member (12) and the coupling member (14). A fixing hole (23) wherein a fixing shaft (22) with flanges (21) extended outward from both ends are fixated while the fixing shaft is penetrated through the fixing hole is formed on each of the fixed surfaces (17, 18). An inner protrusion (24) extended inward and locked and fixated to the flange (21) of the fixing shaft (22) is formed on each of the inner surfaces of the fixed surfaces. The clamp capable of adjusting the fixation angle includes a fixing ring (27) with angle adjusting rods (26) inserted and received in multiple angle adjusting holes positioned at a predetermined angle around the center of the fixing hole (23) of the fixed surfaces (17, 18).</p> |
