Example Embodiment

[0024] In order to make the technical solution of the present invention easier to be understood clearly, the following detailed description will be given in conjunction with the accompanying drawings and the embodiment of the outer window construction of a civil engineering project.

[0025] Reference figure 1 , In the present invention, the outer wall tongue and groove to prevent water seepage of the window, the front structure of which is a rectangular frame 1 set at the opening of the outer window;

[0026] Reference figure 2 The cross-sectional structure of the rectangular frame 1 is a stepped shape 2 with inner height and outer height. The height difference between the indoor portion 21 and the outdoor portion 22 of the stepped shape 2 is 13mm-17mm. The preferred size of this embodiment is 15mm.

[0027] The present invention adopts the aforementioned construction method for preventing water seepage of windows with external wall tongue and groove, and takes the main external wa...

Abstract

The invention discloses an outer-wall tongue groove capable of preventing water seepage of a window and a construction method of the outer-wall tongue groove. The front structure of the outer-wall tongue groove is a rectangular frame arranged in a window hole, and the section structure is in the shape of a step with inside higher. The construction method of the outer-wall tongue groove includes procedures of steel banding of a main outer wall, formwork erecting of the main outer wall, concrete casting, auxiliary frame mounting, JS waterproof construction, outer-wall heat insulation construction and window frame mounting. The concrete structure at the window is designed into a manner of the tongue groove, part of construction methods for preventing water seepage of windows is updated, plugging of post-cast strips of a roof is guaranteed, and occurrence probability of water seepage of the window is decreased. Meanwhile, plastering thickness in the indoor window is reduced during construction, and the purpose for preventing water seepage of the window is achieved.

Description

technical field [0001] The invention relates to the construction of an exterior window of a civil construction project, more specifically, the invention relates to an exterior wall groove and a construction method for preventing water seepage of a window in a civil construction project. Background technique [0002] In civil construction projects, water seepage through external windows is a ubiquitous quality problem that needs to be solved, especially for houses with luxuriously decorated interior spaces, it is even more important to properly solve the problem of water seepage through windows. [0003] On the surface, water seepage in windows or window corners seems to be just a problem with the assembly technology and installation quality of a single finished window, but if you analyze carefully, you can find that the appearance of this quality problem has a lot to do with the concrete structure where the window is fixed . [0004] The conventional concrete structure of t...
