s2, sealing and compacting gaps around the window frame by using a foaming agent, and making a heat insulation material at the outer side part of the window frame according to the requirements of a drawing;

s3, reserving reverse edges with the width of 60mm and the thickness of 30mm at the inner side edge of the window opening, wherein the peripheral dimensions of the reverse edges are less than 5mm of each window frame, the reverse edges play a role of water stopping, grooves with the length of 50mm, the width of 50mm and the depth of 15mm are reserved at the upper and outer edges of the reverse edges, the distance between the grooves is consistent with that between window frame fixing pieces, and the reverse edges are used for sealing the window frame by adopting expansion mortar after the window frame is pasted and fixed;

and S4, after the window frame is manufactured and installed on the site, the window frame can be installed.

(III) advantageous effects

The invention provides a construction method for installing an external window of a concrete prefabricated part. The method has the following beneficial effects:

the method for installing and constructing the outer window of the concrete prefabricated part can effectively ensure the installation and construction quality of the window on the concrete prefabricated part, ensure the potential quality hazards such as water seepage resistance, and has the advantages of good appearance, simple construction, convenient operation, effective cost saving and unnecessary repair, is mainly suitable for the installation of the outer window of the prefabricated part of the prefabricated building, is quick and simple to construct when the window frame is installed, does not need to chisel the periphery of the opening of the part due to the installation of the iron sheets of the door and the window, can prevent the water seepage of the window after the window is installed, can effectively ensure the construction quality, and has good appearance and strong reliability.
