Description

Technical Field

[0001] The utility model relates to the technical field of building doors and windows, and in particular to a fire-resistant window broken bridge aluminum alloy profile structure. Background Art

[0002] At present, in architectural design, the requirements for building fire protection are getting higher and higher, and at the same time, the requirements for building energy conservation are also getting higher and higher. It is necessary to meet several performances of ordinary exterior windows, namely air tightness, water tightness, wind pressure resistance, energy saving, sound insulation, and lighting, and at the same time meet the fire resistance integrity of more than 30 minutes. Therefore, the application of thermal insulation aluminum alloy fire-resistant windows is becoming more and more extensive.

[0003] In high temperature conditions such as fire, if the outer aluminum alloy profile begins to melt due to the high temperature, the structural design and material of the glass support (usually steel, because the melting point of steel is much higher than that of aluminum) can prevent the glass from falling off due to damage to the outer frame. The glass support needs to be firmly connected to the indoor profile, so that when the outdoor profile melts and loses its supporting function, the glass support can form a barrier to prevent the glass from falling off, so the firm fixation of the glass support and the indoor profile is crucial.

[0004] But the traditional ordinary thermal insulation aluminum alloy window frame profiles, such as Figure 1 As shown, the upper surface of the window frame generally has a pressure rib, which is a component in the window frame profile used to enhance the structural strength and improve the sealing performance. It is usually located in the middle or near the middle of the window frame, such as Figure 1 As shown in the middle circle, it is not convenient to fix the glass support and the indoor profile, and the glass support will also affect the installation of the pressure line. There are often two situations:

[0005] (1) Bend the glass support at the pressure line rib of the indoor profile to avoid affecting the installation of the pressure line, but it is often necessary to fix the screws obliquely. The oblique fixing screws are difficult to install and are prone to loose fixing, which reduces the qualified rate of fire-resistant windows;

[0006] (2) Mill grooves on the pressure line ribs on the interior side profile to facilitate the flat fixation of the glass support on the interior side profile. At the same time, it is necessary to mill notches on the pressure line, but positioning and milling ribs increase the construction process and construction difficulty.

[0007] Based on this, it is necessary to study a fire-resistant window broken bridge aluminum alloy profile structure. Utility Model Content

[0008] In view of this, the purpose of the utility model is to provide a fire-resistant window thermal break aluminum alloy profile structure, which can effectively solve the problem that the indoor side profile of the traditional ordinary thermal break aluminum alloy window frame profile structure is not convenient to be fixed with the fire-resistant window glass bracket.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A fire-resistant window broken bridge aluminum alloy profile structure, comprising a broken bridge profile, a glass support and a connecting piece;

[0011] The thermal break profile includes an indoor profile, an outdoor profile and a heat insulation strip; the indoor profile is arranged at intervals on the right side of the outdoor profile, and a heat insulation strip is connected between the indoor profile and the outdoor profile;

[0012] A first pressing rib is disposed on the upper surface of the indoor profile, a fixing area is formed between the first pressing rib and the left end surface of the indoor profile, and a threaded hole is opened on the fixing area;

[0013] The upper surface of the outdoor profile is provided with a second pressing rib;

[0014] The glass support is arranged on the first pressing rib and the second pressing rib, and the left side of the glass support is fixedly connected to the outdoor profile;

[0015] A through hole corresponding to the threaded hole is provided on the right side of the glass support;

[0016] The connecting member passes through the through hole and the threaded hole to fix the indoor profile and the right side of the glass support, and the right end surface of the glass support is located to the left of the right end surface of the first pressing rib.

[0017] Furthermore, a first edge plate is arranged on the top of the first crimping rib, and a second edge plate is arranged on the top of the second crimping rib. The upper surfaces of the first edge plate and the second edge plate are on the same horizontal plane, and the first edge plate and the second edge plate both include a left flange and a right flange.

[0018] Furthermore, the left end surface of the outdoor profile extends upward, and the extended portion is provided with a limiting portion facing the second edge plate;

[0019] A first installation groove with an upper opening is formed between the left end surface of the outdoor profile and the second pressing rib, and a fireproof expansion strip is arranged in the first installation groove;

[0020] The limiting portion and the left flange of the second edge plate are located above the fireproof expansion strip and limit the fireproof expansion strip.

[0021] Furthermore, a second installation groove is formed between the first crimping rib and the second crimping rib, and a fireproof expansion strip is arranged in the second installation groove;

[0022] The left flange of the first edge plate and the right flange of the second edge plate are both distributed above the fireproof expansion strip and limit the fireproof expansion strip.

[0023] Furthermore, the right end surface of the indoor profile extends upward, and the extended portion is provided with a clamping portion facing the first edge plate, and a clamping groove is formed between the clamping portion and the right flange of the first edge plate.

[0024] The beneficial effects of the above technical solution are:

[0025] (1) The utility model reserves a fixing area between the first pressure wire rib and the left end face of the indoor profile, so that the right side of the glass support can be fixed directly, without bending the right side of the glass support, and without milling the pressure wire rib to form an installation space, thus avoiding the oblique fixing of the connecting parts, improving the firmness and reliability of the fixation, and eliminating the rib milling process, reducing the installation difficulty and construction efficiency. In addition, compared with the conventional profile structure in which the right end of the glass support needs to extend to the right over the first pressure wire rib for fixing, the right end face of the glass support in the utility model is located to the left of the right end face of the first pressure wire rib and does not need to extend over the first pressure wire rib, thus avoiding the problem of the right side of the glass support interfering with the pressure wire and needing to mill a notch in the pressure wire, thus simplifying the construction process. In summary, the utility model can effectively solve the problem that the indoor side profile of the traditional ordinary thermally-insulated aluminum alloy window frame profile structure is not convenient to be fixed with the fire-resistant window glass support, avoids oblique fixing and milling wire ribs and milling lines, simplifies the construction process, improves the firmness of the fixation, and improves the qualified rate of fire-resistant window installation.

[0026] (2) The utility model limits the fireproof expansion strip by the limiting part and the left flange of the second edge plate, so that the fireproof expansion strip at the bottom of the indoor groove can be limited and is not easy to fall off; the broken bridge aluminum alloy window connects the inner and outer cavities through the insulation strip to reduce heat transfer and achieve energy saving. However, the aluminum alloy profile has a low melting point and melts quickly in case of fire. By setting the fireproof expansion strip, the flame can be further blocked to ensure the integrity of the indoor profile when a fire occurs in the outdoor profile. The fireproof expansion strip is further limited and installed. Compared with the traditional single bonding and fixing method at the bottom of the groove, it does not rely on the bonding situation. It is not easy to fall off through the limiting effect of the limiting part and the left flange of the second edge plate, thereby improving the qualified rate of fire-resistant window construction.
