Outer window frame waterproof joint structure and construction method thereof

Abstract

The invention provides an outer window frame waterproof joint structure and a construction method thereof. The outer window frame waterproof joint structure comprises a wall, a window frame and an outdoor windowsill, a gap between the window frame and the wall is filled with a filling layer, and the filling layer is composed of a U-shaped filling part using fine stone concrete and an inverted U-shaped filling part using a polyurethane foaming agent; an outdoor closing structure comprises waterproof mortar layers, sealing grooves and sealant; the waterproof mortar layers are coated on the outdoor side of the filling layer, the window frame adjacent to the filling layer, the outdoor side of the wall and the outdoor side of the windowsill; the sealing grooves are circumferentially formed in the waterproof mortar layers along the outdoor side of window frame, and sealed and closed with the sealant. According to the outer window frame waterproof joint structure and the construction method thereof, the fine stone concrete is adopted to replace the polyurethane foaming agent for waterproof filling materials of a lower opening of the window frame, arrangement of the other waterproof rolling material can be avoided, process operation is relatively easy, construction quality control is guaranteed, and the risk of rainwater leakage of an outer window can be reduced.

Description

technical field [0001] The invention relates to the technical field of anti-leakage construction of external windows of buildings, in particular to a waterproof node structure of an external window frame and a construction method thereof. Background technique [0002] During the installation and construction of the external window frame of the building, in order to prevent perennial rain erosion and water seepage of the window frame, in accordance with the detailed design nodes of doors and windows and the requirements of construction specifications, it is necessary to do waterproof filling at the junction of the window frame and the external wall of the building. Usually, after the window frame of the building is fixed, the surrounding of the window frame should be filled with foamed polyurethane, and the surface should be sealed with sealant to prevent rainwater from penetrating into the room. [0003] At present, the filling treatment around the window frame is one of the...
