Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building engineering, in particular to a waterproof structure for building exterior windows. Background Art
[0002] The waterproof construction of building exterior windows is one of the important links in engineering construction. If the waterproof effect of the building exterior windows is poor, there will be a certain risk of leakage. Once water leakage occurs in the building exterior windows, it will have a great impact on the interior, and the subsequent waterproof repair cost will be high.
[0003] In order to solve the waterproof problem of building exterior windows, the waterproof construction method for building exterior windows in the prior art is: the window frame of the exterior window is first fixed with screws to the reserved opening of the main structure of the building, and then the gap between the window frame and the reserved opening is filled with foam glue. The foam glue can further fix the window frame, and then a waterproof layer is made on the upper part of the thermal insulation mortar layer on the outdoor windowsill outside the window frame, and then a water-resistant putty is applied on the waterproof layer, and finally a real stone paint is used to cover the surface. However, due to the poor durability of the foam glue, cracks are easily generated after a long time. When it rains or snows, water is easily accumulated on the outdoor windowsill outside the window frame. At this time, the external water vapor can easily penetrate into the room through the cracks in the foam glue in the bottom area of the window frame; and because the thermal insulation mortar layer will produce a certain deformation with the change of temperature, it will affect the waterproof protection effect of the waterproof layer on the upper part of the thermal insulation mortar layer.
[0004] Therefore, it is urgent to propose a waterproof structure for building exterior windows to solve the above technical problems. Utility Model Content

[0039] like Figure 1 to Figure 3 As shown, an embodiment of the utility model provides a waterproof structure for an exterior window of a building, comprising a window frame 1, a polymer waterproof mortar 2 and an exterior waterproof component 3.
[0040] The window frame 1 is arranged in the reserved hole of the wall 100; the polymer waterproof mortar 2 is filled in the gap between the bottom area of the window frame 1 and the wall 100; the outer waterproof component 3 is arranged on the top surface of the wall 100 at the outer position of the window frame 1, and one side of the outer waterproof component 3 abuts against the window frame 1, and the outer waterproof component 3 includes a first waterproof layer 31, a thermal insulation mortar layer 32 and a surface layer 33, the first waterproof layer 31 is arranged on the top surface of the wall 100 at the outer position of the window frame 1, and the thermal insulation mortar layer 32 and the surface layer 33 are stacked on the first waterproof layer 31 in sequence. That is: the outer waterproof component 3 includes the first waterproof layer 31, the thermal insulation mortar layer 32 and the surface layer 33 stacked in sequence from bottom to top.
[0041] by Figure 1 Take the orientation in as an example, the left side of the window frame 1 is the external environment, and the right side of the window frame 1 is the indoor environment. During the specific construction, the window frame 1 and the wall 100 are first fixed with screws, and then filled with polymer waterproof mortar 2, which is required to be filled densely to ensure no gaps, and finally the top surface of the wall 100 at the outer position of the window frame 1, that is, the outer window sill, is cleaned and the outer waterproof component 3 is installed, and the coverage of the outer waterproof component 3 needs to reach the outermost side of the outer window sill.
[0042] The waterproof structure of the building exterior window provided by the embodiment of the utility model uses polymer waterproof mortar 2 instead of foam glue as a filler in the gap between the bottom area of the window frame 1 and the wall 100. It has good durability and is not easy to crack, and can effectively prevent water vapor from penetrating into the room from the bottom area of the window frame; and in the external waterproof component 3 of this embodiment, the first waterproof layer 31 is directly arranged on the concrete base of the wall 100, and then the thermal insulation mortar layer 32 and the surface layer 33 are sequentially arranged on the first waterproof layer 31. Since the concrete base will not be deformed due to temperature, such an arrangement can ensure the good integrity of the first waterproof layer 31, thereby ensuring the overall waterproof effect of the external waterproof component 3.
[0043] Optionally, the first waterproof layer 31 may be a type II polymer cement waterproof coating (ie, type II JS waterproof coating), a cement-based permeable crystallization waterproof coating, etc. Exemplarily, the thickness of the first waterproof layer 31 may be 1.5 mm.
[0044] like Figure 3 As shown, in some embodiments, the polymer waterproof mortar 2 is located at the bottom edge and left and right sides of the bottom area of the window frame 1, and the height of the polymer waterproof mortar 2 on the left and right sides of the window frame 1 is not less than 200 mm. That is, from the front perspective of the window frame 1, the distribution of the polymer waterproof mortar 2 is U-shaped.
[0045] By extending the polymer waterproof mortar 2 from the bottom edge of the window frame 1 to the left and right sides, the distribution range of the polymer waterproof mortar 2 can be expanded, which is beneficial to further improve the waterproof effect of the building's exterior window waterproof structure.
[0046] Furthermore, the gap between the remaining area of the window frame 1 except the bottom area and the wall 100 is filled with foam glue 4. In this way, the bottom area of the window frame 1 where water easily accumulates is filled with polymer waterproof mortar 2, and the remaining areas are filled with foam glue 4, which can not only improve the overall waterproof effect, but also have the advantages of simple construction and high construction efficiency when using foam glue 4.
[0047] like Figure 2 As shown, in some embodiments, the first waterproof layer 31 is also arranged on the outer surface of the window frame 1. That is, the first waterproof layer 31 includes a first segment horizontally arranged on the top surface of the wall 100 at the outer position of the window frame 1, and a second segment vertically arranged on the outer surface of the window frame 1, and the final first waterproof layer 31 is roughly L-shaped. In this way, waterproof protection can be formed at the abutment position between the outer waterproof component 3 and the window frame 1, further preventing external water vapor from penetrating into the room.
[0048] Optionally, the thickness of the first waterproof layer 31 on the outer surface of the window frame 1 is not less than 10 mm; and the height of the first waterproof layer 31 on the outer surface of the window frame 1 is not less than 200 mm. By limiting the thickness and height of the first waterproof layer 31 on the outer surface of the window frame 1, the waterproof effect at the abutment position between the outer waterproof component 3 and the window frame 1 is guaranteed.
[0049] In some embodiments, the thermal insulation mortar layer 32 includes a mortar body and an alkali-resistant glass fiber mesh cloth, wherein the alkali-resistant glass fiber mesh cloth is located inside the mortar body. By pressing the alkali-resistant glass fiber mesh cloth into the thermal insulation mortar layer 32 during construction, the integrity of the thermal insulation mortar layer 32 can be enhanced to prevent the thermal insulation mortar layer 32 from cracking due to temperature changes.
[0050] Optionally, the thermal insulation mortar layer 32 may be an inorganic thermal insulation mortar layer, an organic thermal insulation mortar layer or a composite thermal insulation mortar layer, which is not specifically limited herein.
[0051] like Figure 2 As shown, in some embodiments, the top surface of the thermal insulation mortar layer 32 is provided with a drainage slope, and the top surface of the surface layer 33 is provided with the same drainage slope as the thermal insulation mortar layer 32. In this way, external water can flow down along the drainage slope, which is conducive to avoiding water accumulation on the top surface of the outer waterproof component 3.
[0052] like Figure 2As shown, in some embodiments, the surface layer 33 includes a second waterproof layer 331 , a flexible water-resistant putty 332 and a real stone paint 333 which are stacked in sequence, and the second waterproof layer 331 is attached to the top surface of the thermal insulation mortar layer 32 .
[0053] Through such an arrangement, the surface layer 33 covers the thermal insulation mortar layer 32, and the second waterproof layer 331 in the surface layer 33 provides waterproof protection for the thermal insulation mortar layer 32. The flexible water-resistant putty 332 and the real stone paint 333 not only have certain waterproof properties, but also prevent the building surface from weathering and reduce the risk of wall cracking.
[0054] Among them, the second waterproof layer 331 can be a 5mm thick dry powder polymer cement waterproof mortar, or a polymer cement waterproof coating (i.e. JS waterproof coating), etc., which is not specifically limited here.
[0055] Further, the number of coating layers of the flexible water-resistant putty 332 is two layers. Such an arrangement can better fill the pits and unevenness of the wall surface, is conducive to forming a flat and smooth base, provides a good foundation for the subsequent coating of the real stone paint 333, and can further enhance the waterproof performance.
[0056] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
