Technical Field

[0002] Glass partition profiles are an integral part of modern architectural design, providing stable support and enhancing aesthetics. Depending on the requirements, glass can be single-layer, double-layer, laminated, or vacuum-coated. Single-layer glass partitions allow for excellent daylighting, while double-layer glass partitions offer enhanced thermal, heat, and sound insulation.

[0003] Existing profiles used for glass partitions are mostly formed by hot-rolling several components and then welding them together. Over time, these welds can crack or fall off, requiring maintenance and repair. The large number of welds increases the difficulty and cost of inspection and maintenance. Furthermore, the profiles are bulky, heavy, and lack rigidity. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, the central cavity is provided, which not only provides an embedding position for screws, angle brackets, etc. driven into the material, but also reserves a central cavity for the overall profile to increase the cross-sectional moment of inertia of the profile. The larger the cross-sectional moment of inertia, the less likely the profile is to deform when subjected to bending force, thereby improving the overall rigidity of the profile.

[0021] 2. In the present invention, the recessed groove provides an anchor point for the self-tapping screw, which plays a guiding role when the screw tip reaches the keel surface, thereby preventing the high-speed rotating screw from deflecting.

[0022] 3. In the present invention, by providing grooves on the side walls of the strip-shaped grooves as aluminum profile clamping points, the aluminum profiles can be prevented from moving due to overall vibration after being clamped.

[0023] 4. In the present invention, the keel is formed into one piece by cold pressing the plate and then laser seamlessly welded at the center of the strip groove. Since the splicing surface is reduced, the one-piece formed keel can better resist deformation caused by external factors such as changes in environmental temperature and humidity, thereby greatly improving its anti-deformation ability.

[0024] 5. In the present invention, the anti-slip fixing strip placed between the glass and the keel not only facilitates the stable assembly between the glass and the keel, but also can absorb a large amount of ambient heat in a short period of time in emergency environments with high temperature and high heat such as fire, providing time margin for rescue and improving the safety of product use.

The cross-section of the keel comprises a central cavity 1, a pair of opposing tapered grooves 2, and a pair of strip grooves 3 adjacent to the tapered grooves 2. The cavities on either side of the tapered grooves 2 form the sidewalls of the strip grooves 3. Reserving the central cavity for the overall profile increases the profile's moment of inertia. A greater moment of inertia makes the profile less susceptible to deformation when subjected to bending forces, thereby improving the profile's overall rigidity.

[0038] The conical groove 2 is a dovetail-shaped groove, and the side of the conical groove 2 close to the central cavity 1 is wider than the side away from the central cavity 1 .

[0039] Among them, a concave point groove 21 for self-tapping screw limiting is provided at the center of the bottom of the conical groove 2. The setting of the concave point groove provides an anchor point for the self-tapping screw, which plays a guiding role when the screw tip reaches the keel surface, preventing the high-speed rotating screw from deflecting.

The grooves are set on the side walls of the strip groove as aluminum profile clamping points.
