Description

Technical Field

[0001] This utility model relates to the field of building curtain wall structure technology, and in particular to a wind-resistant aluminum profile structure suitable for curtain wall systems. Background Technology

[0002] With the widespread construction of high-rise buildings in cities, the structural strength and wind pressure resistance of curtain wall systems, as an important component of building envelopes, have become particularly crucial. Traditional aluminum curtain wall profiles often adopt single-cavity or simple multi-cavity structures. Due to the lack of scientific mechanical support design, they often deform, leak, or even fail under high wind pressure, especially in typhoon-prone or high-altitude areas.

[0003] While existing technologies include solutions that use reinforcing ribs or filler materials to enhance profile performance, the following issues still exist:

[0004] 1. The reinforcement arrangement is simple and the bending resistance is limited;

[0005] 2. The connection structure is simple, which poses a risk of slippage or loosening of the assembly;

[0006] 3. Lack of an effective water drainage path leads to condensation buildup and corrosion problems;

[0007] 4. The installation method is obviously exposed, which is not conducive to aesthetics and sealing.

[0008] Therefore, there is an urgent need for a new type of aluminum profile structure for curtain walls that is structurally reinforced, reliably connected, and possesses waterproof and heat insulation properties. Utility Model Content

[0009] The purpose of this invention is to provide a wind-resistant aluminum profile structure suitable for curtain wall systems, so as to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A wind-resistant aluminum profile structure suitable for curtain wall systems, the aluminum profile comprising:

[0012] The main cavity is used to provide support for the main structure.

[0013] At least two symmetrically distributed auxiliary cavities are located on both sides of the main cavity to enhance lateral stiffness;

[0014] An air-sealing cavity, located at the end of the aluminum profile, is used to block airflow to enhance airtightness.

[0015] The cavities are separated by reinforcing ribs, and the reinforcing ribs have thickened sections in the main force direction;

[0016] The aluminum profile is provided with a triple locking structure at both ends, including staggered teeth, wedge-shaped limiting grooves and anti-slip tongue structure, to achieve anti-slip and self-locking positioning between the aluminum profiles;

[0017] The aluminum profile is also equipped with a water guiding channel inside, which runs through the bottom of the cavity, and has a hidden connecting groove on the outside for connecting the glass pressure plate and the sliding fitting.

[0018] Furthermore, the wall thicknesses of the main cavity and the auxiliary cavity are 2.0 mm and 1.5 mm, respectively.

[0019] Furthermore, the reinforcing ribs are in the form of a "T" shape and are vertically connected to the wall of each cavity.

[0020] Furthermore, the airtight cavity is filled with foamed insulation material to enhance the heat insulation effect.

[0021] Furthermore, the anti-sway tongue structure in the triple locking structure is disposed on the longitudinal extension surface of the aluminum profile to limit the lateral displacement of the profile.

[0022] Furthermore, the hidden connection slot is T-shaped to conceal the slide-in fitting.

[0023] Furthermore, the water guiding channel is provided with downward-sloping drain holes to facilitate the drainage of condensate or seepage water out of the profile.

[0024] Furthermore, the aluminum profile is subjected to anodizing or fluorocarbon spraying to improve its corrosion resistance and surface durability.

[0025] Furthermore, the aluminum profile and glass curtain wall unit are structurally assembled using mounting bolts and sliding fittings.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. This wind-resistant aluminum profile structure suitable for curtain wall systems achieves uniform stress distribution under wind load by adopting a combination design of multi-cavity structure and thickened reinforcing ribs, which greatly improves the overall stiffness and deformation resistance of the profile. It is particularly suitable for the structural stability requirements of high-rise building curtain wall systems under extreme climatic conditions such as typhoons and high negative pressure.

[0028] 2. This wind-resistant aluminum profile structure suitable for curtain wall systems adopts a triple locking structure (staggered teeth + wedge groove + anti-sway tongue) to effectively prevent loosening, slippage and vibration failure. At the same time, combined with the design of hidden connection groove and water guide channel, it achieves excellent sealing, aesthetics and drainage functions, effectively extending the service life of the curtain wall system and improving the overall weather resistance and safety.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0036] like Figures 1 to 5 As shown, the aluminum profile structure (100) of this utility model adopts a symmetrical multi-cavity closed section design, which is composed of a main cavity (110), auxiliary cavities (111, 112) and a closed cavity (113). The cavities are separated by several reinforcing ribs (120), and the reinforcing ribs in the main force direction are provided with a thickened section (121), the thickness of which is preferably 3.0 mm, which increases the bending strength by more than 30% compared with the thickness of the auxiliary ribs (2.0 mm).

[0037] The structure preferably uses 6063-T5 aluminum alloy profiles, which are extruded, solution heat treated, and naturally aged to ensure both the strength of the profiles and excellent surface quality. The reinforcing ribs are in the form of "T" or cross shapes, installed perpendicular to the stress surface, and "recessed transition sections" are set at both ends of the main cavity to prevent stress concentration.

[0038] like Figure 3As shown, a triple locking connection structure (130) is provided at the end of the profile (100), which includes:

[0039] The toothed interlocking structure (131) has a tooth width of 3 mm and a depth of 1.5 mm in each group, with a total of 6 groups;

[0040] Built-in wedge-shaped limiting groove (132) for insertion positioning and to prevent slippage;

[0041] The vertically inserted anti-sway tongue structure (133) forms a three-dimensional locking connection with the adjacent profile, enhancing the overall connection stability.

[0042] like Figure 4 As shown, a water guiding channel (140) is provided at the bottom of the profile, with an internal inclination angle of 3°, and a drain hole (141) is provided below it with a diameter of [missing information]. The 300mm spacing effectively guides rainwater or condensate outwards, preventing water accumulation and corrosion. A concealed connecting groove (150) is provided on the outside of the channel for embedding the glass pressure plate and sliding fittings (400), ensuring a smooth and aesthetically pleasing outer surface.

[0043] To meet the thermal performance requirements of the exterior walls of high-rise buildings, the closed cavity (113) is filled with polyurethane foam (160), whose thermal conductivity is not higher than 0.025W / (m·K), and maintains stable performance under operating conditions from -20℃ to +70℃, thereby improving the overall thermal insulation performance.

[0044] like Figure 5 As shown, in the application, the aluminum profile (100) is fixedly connected to the glass curtain wall unit (200) by mounting bolts (300) and sliding fittings (400), the structure is firmly connected, and the sliding fittings are located in the concealed connection groove (150) to ensure the overall airtightness, watertightness and mechanical strength of the system.

[0045] The entire profile structure can be formed in one step using standard profile extrusion molds, reducing the complexity of the processing technology. At the same time, the staggered tooth connection achieves "quick insertion + no welding + high-strength positioning", which is very suitable for modern prefabricated unitized construction of curtain walls.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
