PURPOSE: A washer plate structure for absorbing expansion/contraction force and preventing the separation of joints when installing a temporary footbridge for bridges is provided to prevent the separation of connecting parts caused by the swaying of a footbridge when installing a temporary footbridge at the side of a bridge, and to maintain a stable stationary state by absorbing expansion/contraction force when expansion/contraction deformation of a bridge occurs. CONSTITUTION: A washer plate structure for absorbing expansion/contraction force and preventing the separation of joints when installing a temporary footbridge for bridges includes multiple anchor sockets, a fixing frame(300), a washer plate(400), a supporting frame(520), a foothold, and a handrail. The multiple anchor sockets are combined with a bridge side(100), and combines with a fastener. The fixing frame is pressed or hooked to the bridge side, and supports the washer plate at the bridge side. The washer plate is pressed to the fixing frame and thereby prevents loosening of the fastener. The supporting frame is pressed to the washer plate and forms a temporary footbridge. The foothold forms the top of the supporting frame. The handrail is installed to be standing at the outermost end of the supporting frame. |
