Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile technology, specifically a high-strength mullion profile for system windows. Background Technology

[0002] System windows are high-performance windows that offer superior thermal insulation, sound insulation, security, aesthetics, and ease of maintenance through systematic design and the use of high-quality materials. The mullions of a system window consist of horizontal and vertical mullions. The vertical mullions directly support the horizontal mullions, and the horizontal mullions directly support the glass. The structural strength of the entire window is ensured through the fixed connection between the vertical and horizontal mullions and the frame. The frame and mullion profiles are typically made of high-strength aluminum alloy or thermally broken aluminum to ensure durability and thermal insulation performance.

[0003] During window installation, leveling is required. However, due to unevenness in the concrete substrate during construction, the window and the underlying concrete substrate cannot perfectly align. This necessitates using shims to level the surface and then filling the gaps with expanding foam. The shims have a small supporting area, and the expanding foam has almost no load-bearing capacity, causing the weight of the glass to primarily fall on the mullions. Over time, this easily leads to mullions bending and deforming, affecting the sealing of the system window and the smoothness of its opening and closing. Therefore, the structural strength of the mullions is crucial. Consequently, this design proposes a novel high-strength mullion profile for system windows. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-strength mullion profile for system windows, which further improves structural strength based on existing technologies.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A high-strength mullion profile for a system window includes an inner profile, a connecting strip, and an outer profile. The top and bottom of the inner wall of the main cavity of the inner and outer profiles are respectively provided with an upper web and a lower web, and the upper web and the lower web are respectively provided with axial tie rods.

[0007] The connecting strip includes an outer frame and an inner horizontal stiffening plate. Diagonal bracing plates are provided between the outer frame and the horizontal stiffening plate, as well as between adjacent horizontal stiffening plates.

[0008] The outer and inner profiles are respectively provided with inner and outer slots on their opposite surfaces. The inner slots are symmetrically distributed above and below the outer slots. The connecting strip is provided with inner and outer strips on both sides, and the inner and outer strips are respectively engaged with the inner and outer slots.

[0009] Preferably, the two sides of the upper web plate are inclined upward and form an inverted trapezoidal structure with the upper walls of the inner and outer profiles, and the two sides of the lower web plate are inclined downward and form a trapezoidal structure with the lower walls of the inner and outer profiles.

[0010] Preferably, the tie rods on the upper and lower webs are respectively located at the bottom of the upper and lower webs.

[0011] Preferably, the surface of the tie bar facing away from the upper and lower web plates has a convex smooth curved surface structure, and multiple tie bars are equidistantly arranged on the upper and lower web plates in the transverse direction.

[0012] Preferably, the distance between the upper web and the lower web is not less than half the height of the main cavity of the inner and outer profiles.

[0013] Preferably, the horizontal stiffeners inside the connecting strip are provided in at least two layers, and the diagonal bracing stiffeners are in an "inward" or "outward" structure, and the vertically adjacent diagonal bracing stiffeners inside the outer frame have opposite inclination directions.

[0014] Preferably, the inner groove is a dovetail groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention, based on the use of high-hardness aluminum alloy as raw material and the thickening of the inner and outer profiles, increases structural strength and support by incorporating upper and lower webs and tie rods inside the inner and outer profiles. This increases the vertical load-bearing capacity and compressive strength of the aluminum alloy profiles. Furthermore, by incorporating horizontal and diagonal bracing plates inside the connecting strip and adding external clamping strips on both sides of the connecting strip, the structural strength of the connecting strip is increased, while also enhancing the interlocking effect with the inner and outer profiles. As a result, the overall structural strength is further improved compared to existing technologies. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-3 As shown, this utility model provides a technical solution: a high-strength mullion profile for a system window, including an inner profile 1, a connecting strip 2, and an outer profile 3. The top and bottom of the inner wall of the main cavity of the inner profile 1 and the outer profile 3 are respectively provided with an upper web plate 4 and a lower web plate 5. The two sides of the upper web plate 4 are inclined upward and form an inverted trapezoidal structure with the upper wall of the inner profile 1 and the outer profile 3. The two sides of the lower web plate 5 are inclined downward and form a trapezoidal structure with the lower wall of the inner profile 1 and the outer profile 3. The distance between the upper web plate 4 and the lower web plate 5 is not less than half the height of the main cavity of the inner profile 1 and the outer profile 3.

[0023] The upper web 4 and the lower web 5 are respectively provided with axial tie rods 6. The tie rods 6 on the upper web 4 and the lower web 5 are respectively located at the bottom of the upper web 4 and the lower web 5. The tie rods 6 are convex and smooth curved surface structures facing away from the surface of the upper web 4 and the lower web 5. There are multiple tie rods 6 on the upper web 4 and the lower web 5 arranged at equal intervals in the transverse direction.

[0024] The connecting strip 2 includes an outer frame 201 and an inner horizontal stiffener 202. Diagonal bracing 203 is provided between the outer frame 201 and the horizontal stiffener 202 and between adjacent horizontal stiffeners 202. The horizontal stiffener 202 in the connecting strip 2 has at least two layers. The diagonal bracing 203 has an "inward" or "outward" structure, and the vertically adjacent diagonal bracing 203 inside the outer frame 201 has opposite inclination directions.

[0025] The outer profile 3 and the inner profile 1 are respectively provided with inner groove 7 and outer groove 8 on their opposite surfaces. The inner groove 7 is a dovetail groove. The inner groove 7 is symmetrically distributed above and below the outer groove 8. The two sides of the connecting strip 2 are respectively provided with inner strip 204 and outer strip 205, which are engaged with the inner groove 7 and the outer groove 8 respectively.

[0026] Working principle:

[0027] Based on using high-hardness aluminum alloy as raw material and thickening the walls of the inner profile 1 and the outer profile 3, the structural strength and support effect are increased by setting an upper web plate 4, a lower web plate 5 and a tie rod 6 inside the inner profile 1 and the outer profile 3. This increases the vertical load-bearing capacity and compressive strength of the aluminum alloy profile. By setting a horizontal stiffener 202 and a diagonal bracing stiffener 203 inside the connecting strip 2 and adding an outer clamping strip 205 on both sides of the connecting strip 2, the structural strength of the connecting strip 2 is increased, and the interlocking effect with the inner profile 1 and the outer profile 3 is also increased. This further improves the overall structural strength based on the existing technology.
