Double-tongue-and-groove heat insulation window structure and mounting method

Abstract

The invention discloses a double-tongue-and-groove heat insulation window structure and a mounting method. The structure comprises a base layer wall, an auxiliary frame and a window frame. A double-tongue-and-groove structure is arranged on the inner periphery of a window opening in the base layer wall and comprises a first tongue-and-groove and a second tongue-and-groove, and the double-tongue-and-groove structure is in an upward step shape from outside to inside. The auxiliary frame is arranged in the second tongue-and-groove, the inner side face of the auxiliary frame is tightly attached tothe vertical face of the second tongue-and-groove, a foaming rubber layer is arranged between the auxiliary frame and the inner periphery face of the second tongue-and-groove, a windowsill heat insulation layer is arranged on the outer side of the auxiliary frame and outside the vertical face of the first tongue-and-groove, the vertical height of the windowsill heat insulation layer can cover a window frame and auxiliary frame connecting seam, and a wall heat insulation layer with the outer edge flushed with the outer edge of the windowsill heat insulation layer is arranged on the vertical face of the outer side of the base layer wall. The window structure has the characteristics of being good in heat insulation and energy saving effect and excellent in water seepage prevention performance, the mounting process of the window structure is simple and easy to operate, and it can be guaranteed that the window structure has high fixing strength and mounting precision.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a double-groove thermal insulation window structure and an installation method. Background technique [0002] In ordinary civil construction projects, the insulation at the window is often designed as 2-3cm insulation board or insulation slurry, which has a high heat transfer coefficient and has high heat transfer compared with the building's external wall insulation, that is, there is a thermal bridge. The thermal bridge around the window has many hidden dangers. On the one hand, the thermal bridge increases the heat loss and reduces the energy-saving efficiency of the building; Great impact on living comfort. Secondly, the fire incidents of building exterior wall insulation systems continue to occur, and the fire safety of building materials is particularly important. [0003] In addition, water seepage in building windows is a ubiquitous quality problem that ne...
