A prefabricated leak prevention window frame is provided to make construction simple, to improve work efficiency and to stabilize a structure by assembling an upper frame on a lower frame in a one-touch method without using fasteners such as screws, etc., and to cut down on manufacturing costs, to prevent a leakage of water and to improve in appearance by using a thinned lower frame. A prefabricated leak prevention window frame comprises: a lower frame(10) folded in the appointed shape to be installed on a wall and provided with bearing planes(10c,10d) to support the object, drainage guide planes(10a) inclined downward to drain off stagnant water such as rainwater to the outside through a drain hole(16) and holders(11) to couple with the object; and an upper frame(20) formed in the appointed shape to be installed on the lower frame and provided with guide rails(20a) to guide a window, supported by the bearing planes of the lower frame and provided with setting grooves(21) to couple with the holders in a one-touch method. |
