ABSTRACT:
A construction method for one-step grout fixed window frames on external walls of a concrete-structured building includes the following steps. A window frame including vertical and horizontal sections is fixed with vertical lining boards to the inner side of its vertical sections to form a window frame assembly, and is then supported on an upper supporting board which has been securely attached to a concrete template of an external wall of the building. Template sealing strips are separately attached to an exterior edge and an interior edge of the vertical sections and the upper horizontal section of the window frame assembly, so that a complete moulding cavity is formed. Into this moulding cavity the grouting concrete is grouted and the window frame is inlaid in the concrete after the concrete is set and the concrete templates are removed. With this one-step grout fixed window frame construction method, the periphery of window frames is given good waterproof ability and beautiful appearance, and the construction cost and term are both reduced.
