[0011] Such as figure 1 , figure 2 with image 3 As shown, the method for connecting the corner couplings of the plastic-steel doors and windows of the present invention is as follows: firstly, a reinforcing member 3 that matches the inner cavity of the plastic profile is made, and during implementation, the two-phase couplings are coupled for the L-shaped butted corner couplings of the plastic-steel doors and windows. After inserting the steel liner 1 into the cavity of the plastic profile 2, the distance from one end of the plastic profile 2 to the coupling end of the plastic profile 2 is greater than 1-5 mm than the length of the right-angle side of the reinforcement 3, so as to overcome the steel liner 1, the reinforcement 3 and the plastic profile 2 The effect of deformation due to different shrinkage and expansion rates. Then, the pre-prepared L-shaped reinforcement 3 is inserted into the cavities of two adjacent plastic profiles 2, and the operation process is simple. At t...
