Description

Sealed connection structure of aluminum alloy window frame

technical field

The invention relates to a structure that prevents rainwater leakage and improves the airtightness of the aluminum alloy window by connecting the frame of the aluminum alloy window with the wall of the opening, especially an aluminum alloy window that has the functions of significantly improving waterproof, windproof and heat preservation. Frame sealing connection structure.

Background technique

At present, aluminum alloy windows are widely used in commercial residential buildings and building curtain wall projects. The connection between the aluminum alloy window frame and the wall of the opening is the most common part of rainwater leakage; the main reasons are:

1. The filling material at the connection part does not fill the gap between the frame of the window frame and the wall of the opening, forming a hollow phenomenon or crack;

2. The size of the hole in the wall cannot meet the design requirements, causing the gap between the outer dimension of the window frame and the wall of the hole to exceed the specified range. If the gap is too small, it will not be possible to fill the material. If the gap is too large, it will be difficult to fix the doors and windows and not easy to fill. produce cracks, etc.;

3. The seal between the aluminum alloy window frame and the wall of the opening is easy to cause seal failure due to external force. Therefore, through structural design, it is very necessary to avoid the leakage of the connection between the aluminum alloy window frame and the wall of the opening, and to reduce rework and economic losses caused by rainwater leakage.

In order to solve the above-mentioned problems existing in the connection between the aluminum alloy window and the wall of the opening, the patent announcement number is CN104074434A "A Structure and Construction Method for an Aluminum Alloy Window". It is fixed on the window hole wall; polyurethane caulking foam is filled between the aluminum alloy frame and the steel frame and between the steel frame and the window hole wall; the inner and outer walls of the window hole wall are coated with thermal insulation mortar, and the outer wall of the window hole wall is The insulation mortar is pasted with facing bricks. Attempts are made to fill foam material and waterproof mortar between the aluminum alloy window and the steel sub-frame, and between the steel sub-frame and the wall of the opening, so as to improve the anti-leakage effect of the edge of the door and window and solve the waterproof problem of the aluminum alloy window. The patent publication number is CN104213800A "anti-leakage combined aluminum alloy window and its installation method" and the patent announcement number CN204199947U "anti-leakage combined aluminum alloy window". The disclosed aluminum alloy window structure mainly includes: The sub-frame fixed in the window hole has a waterproof mortar layer between the sub-frame and the wall in the window hole; the waterproof membrane is installed outside the window hole, one end of the waterproof membrane is attached to the inner surface of the sub-frame, and the other end is along the The outer corner surface of the outdoor wall is extended; the main frame is fixed on the inner side of the sub-frame, and the joint between the main frame and the plastering layer is provided with a sealant. An attempt was made to form a sealing line between the steel sub-frame and the wall of the opening to solve the problem of water seepage in the traditional aluminum alloy window structure and the problem of being easily damaged and polluted by civil construction.

However, in actual construction, it is found that waterproof mortar is mainly used in civil structures. The steel sub-frame and aluminum alloy frame are metal materials. The two materials are not compatible, and gaps are likely to occur, causing rainwater to leak; the waterproof membrane material itself is soft. , Thin, directly laid on the outer layer of the hole structure, the frame and the joint position need special treatment to ensure the sealing effect, the actual operation is very difficult, it is difficult to achieve a complete waterproof sealing line, and the expected anti-seepage effect cannot be achieved.

Contents of the invention

The purpose of the present invention is to provide a sealed connection structure of aluminum alloy window frames, which solves the problems of insufficient filling of the gap between the aluminum alloy window frame and the wall of the opening, and rainwater leakage. The filling is full and dense, without cracks, and the sealing connection is reliable, which can effectively prevent rainwater leakage, and significantly improve the airtightness, waterproof, windproof, and heat preservation functions of aluminum alloy windows.

The technical solution adopted in the present invention is: the aluminum alloy window frame sealing connection structure includes an aluminum alloy window frame with a steel sub-frame and a stone panel fixed on the wall of the opening, and its technical points are: the aluminum alloy window frame The steel sub-frame is fixed on the wall of the hole through the fixing sheet and thermal insulation foam material. The frame of the aluminum alloy window frame and the wall of the hole are sealed and connected with a waterproof rubber plate. One end of the waterproof rubber plate is connected to the aluminum alloy window through stainless steel screws. After the border of the frame is connected and fixed, it is sealed with the stone panel by a sealing material, the other end of the waterproof rubber plate is connected and fixed with the wall of the hole by shooting nails, and the gap between the bottom of the waterproof rubber plate and the wall of the hole is sealed with sealant. The gap between the waterproof rubber sheet and the steel sub-frame is filled with thermal insulation material.

The aluminum alloy window frame and the steel sub-frame are connected and fixed by positioning screws.

The steel sub-frame is connected with the fixed piece by rivets, and the fixed piece is fixed on the wall of the hole with nails.

The advantages and positive effects of the present invention are: since the steel sub-frame of the aluminum alloy window of the present invention is fixed on the wall of the opening through the fixing piece and the thermal insulation foam material, a waterproof rubber plate is used between the frame of the aluminum alloy window and the wall of the opening The sealing connection, the waterproof sealing line formed in advance, improves the watertightness and airtightness of the aluminum alloy window, so its structural design is reasonable, ensuring that the gap is filled full and dense, without cracks, and the sealing connection is reliable. Because one end of the waterproof rubber plate is connected and fixed with the frame of the aluminum alloy window frame by stainless steel screws, it is sealed with the stone panel by a sealing material, and the other end of the waterproof rubber plate is connected and fixed with the wall of the hole by a nail. The gap between the aluminum alloy window frame and the wall of the hole is sealed with sealant, and the gap between the waterproof rubber plate and the steel sub-frame is filled with thermal insulation materials, so the gap between the aluminum alloy window frame and the wall of the hole is completely sealed, effectively preventing the aluminum alloy window from cracking. Rainwater seepage, but also improve the thermal insulation performance of aluminum alloy windows.

In addition, the reason why the optimized use of waterproof rubber sheets can avoid the problems of rainwater caused by traditional waterproof mortar and waterproof membrane is mainly because the waterproof rubber sheets are connected by screws, and the joints can be sealed with glue. The seams can also be directly lapped and glued; the gap between the waterproof rubber sheet and the steel sub-frame is completely filled with thermal insulation materials, which avoids defects such as cold bridges caused by the exposed sub-frame, and condensation water inside the aluminum alloy window. Therefore, the invention successfully uses the waterproof rubber sheet, which solves the problems of rainwater leakage due to improper filling of the gap between the aluminum alloy window frame and the opening wall, and significantly improves the airtightness, waterproof, windproof, and heat preservation of the aluminum alloy window. and other functions.
