Trace-free assembly clamp plate used for ship construction

The utility model relates to the technical field of ship construction and particularly relates to a trace-free assembly clamp plate used for ship construction. The clamp plate is provided with a clamp plate body, wherein a clamping slot which is vertically communicated with the bottom surface of the clamp plate is formed on the clamp plate body; and a plurality of special-shaped segments are laterally formed on the upper half segment of the clamping slot. By virtue of the trace-free assembly clamp plate, during the process of carrying out ship structure welding, a ship structure and a ship plate can be pre-fixed without welding lateral support rods, so that not only can the time and cost for pre-fixation and further treatment be saved, but also welding stains and welding spots can be prevented from being left on the surface of the ship structure, the neat appearance of the ship structure can be protected, and the trace-free assembly of the ship structure can be realized.
