Description

Aluminum alloy window anti-leakage structure

technical field

The utility model relates to an aluminum alloy window anti-leakage technology.

Background technique

Leakage after window installation is a long-standing problem in the construction industry. The civil engineering unit is responsible for the structure and the closing of doors and windows. The installation unit is generally responsible for the installation and installation of windows. It caused disputes among several units. This part did not require a waterproof layer, and the leakage was inseparable from each unit, but it was difficult to tell which unit had construction problems. In fact, many aspects are involved in the window area, and there are problems with the construction interface of several units.

Fujian and Zhejiang along the southeast coast are attacked by typhoons many times a year. Various residential projects have leakage phenomena in different degrees during typhoon-prone seasons, mainly in wall leakage, roof leakage, equipment and wall leakage. Leakage of joints, leakage of doors and windows, etc. The joint between the window and the wall is the weakest part of the exterior wall for waterproofing. The leakage of the exterior window usually occurs at the window eyebrow, that is, the upper face of the exterior window.

Utility model content

The technical problem to be solved by the utility model is to provide an anti-leakage structure of an aluminum alloy window, which can cut off the rainwater leakage channel, ensure the sealing performance of the outer window in a typhoon state, and avoid the leakage phenomenon of the outer window during a typhoon.

In order to solve the above technical problems, the utility model adopts the following technical scheme: the anti-leakage structure of the aluminum alloy window includes the wall, and the aluminum alloy window frame is installed on the window sill of the wall, and the feature is that the window sill is placed on the window frame The inner side is provided with a window sill plastering closure to cover the bottom of the window frame, and a sealant is provided between the inner edge of the window sill plastering closure and the window frame for sealing. The edge of the drape board and the window frame are sealed with sealant.

Preferably, the plane of the window sill is a three-level stepped structure descending from the inside of the wall to the outside, wherein the plane of the second step is inclined downward.

Preferably, the window frame is installed above the adjoining part of the second step and the third step, polyurethane foam is provided between the window frame and the step, and the polyurethane foam is L-shaped and embedded in the second step On the steps and the third step, the plastered closing part of the window sill is filled in the gap surrounded by the second step and the window frame.

Preferably, the outer side of the wall is provided with an insulation layer, an outer plastering layer of the insulation layer and an exterior wall finish layer, the window sill is provided with an insulation layer, and the outer edge of the water draping board covers the upper part of the exterior wall finish layer. .

Preferably, the water draping board is made of 1.2 mm thick steel plate.

Preferably, the window frame is fixed on the polyurethane foam by self-tapping screws, and there is also a "ji"-shaped tie piece under the window frame, and the bottom surfaces of the "ji"-shaped tie piece on both sides are formed by The nails are respectively fixed on the second step and the third step.

According to the feature that water seepage mainly seeps into the room from the window sill, the utility model adds a water draping board on the outer window sill to fundamentally cut off the channel of rainwater leakage on the window sill and block the rainwater outside, so that even if the outer window sill has gaps in the insulation layer and the concrete cracks Wait, the rainwater falls into the window sill and flows outward after the drape board and cannot infiltrate. All sides of the inner wall of the window opening on the side of the traditional outer window frame are flat. Although the sealing material is used to fill the gap between the window frame and the window opening wall, any process during the construction process may cause leakage around the window frame. Especially when there is heavy wind and rain, the rainwater will penetrate and expand indoors through the mortar layer from the gap between the lower frame of the window and the bottom surface of the window hole. And the periphery of the window hole of the present invention (except for the upper opening on the top of the window) adopts the stepped concrete water-stop sill type (the reserved size is 10mm smaller than the processing size of the window frame), which can effectively solve the common quality problem of leakage around the window frame. Since the opening of the outer window is improved to a concrete ladder type, the concrete water-stop sill at the lower opening of the window naturally plays a role of water blocking; and the inner corner of the side of the window opening is a water guide line. Once water enters the inner corner, it will flow smoothly. The inner corner line is led downward to the plane gap, so that the leakage problem at the frame edge of the outer window opening can be effectively controlled.
