Description

Technical Field

[0001] The utility model relates to the field of square tubes, in particular to an inner corner reinforcement piece of a high-strength square tube. Background Art

[0002] High-strength square tubes are tubular structural materials with a square cross-section and uniform wall thickness, offering high strength and rigidity. These tubes are typically made from high-strength steels, such as structural steel and alloy steel, hence the name "high-strength square tubes." Due to their excellent mechanical properties, good processability, and relatively low weight, high-strength square tubes are widely used in building structures, machinery manufacturing, automobile manufacturing, bridge construction, railway vehicles, shipbuilding, petrochemical engineering, power engineering, agricultural machinery, storage racking, and decorative engineering.

[0003] In many high-load usage scenarios, the inner corners of square tubes often become weak links. Since stress concentration is prone to occur here, conventional square tube reinforcement methods mainly include external welding reinforcement plates, which not only increases the overall weight of the structure but also affects the overall aesthetics. At the same time, the welding construction process is relatively complicated, requiring not only professional welding equipment and technicians, but also takes a long time to construct and increases project costs. Therefore, we propose a high-strength square tube inner corner reinforcement to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a high-strength square tube inner corner reinforcement to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A high-strength square tube inner corner reinforcement comprises a square tube body, the inner wall of the square tube body is fixedly connected with an angled corner, the inner wall of the square tube body is provided with two slots, the inner walls of the two slots are jointly clamped with a reinforcement body, the inner wall of the square tube body is fixedly connected with a reinforcement core, the outer surface of the reinforcement body is fixedly connected with a reinforcement rib, the outer surface of the reinforcement body is provided with an angled corner, the inner wall of the reinforcement body is fixedly connected with a plate core, the outer surface of the plate core is provided with a heat treatment layer, and the outer surface of the heat treatment layer is provided with a corrosion-resistant layer.

[0007] In a further embodiment, two mounting blocks are fixedly connected to the outer surface of the reinforcement body, and a fixing pin is threadedly connected to the outer surface of each mounting block. The reinforcement body is fixedly connected to the square tube body through the mounting blocks and the fixing pins.

[0008] In a further embodiment, a sound insulation layer is fixedly connected to the outer surface of the reinforcement core, and the outer surface of the sound insulation layer is fixedly connected to the inner wall of the square tube body.

[0009] In a further embodiment, a parameter plate is provided on the front side of the reinforcement body, and the back side of the parameter plate is fixedly connected to the front side of the reinforcement body.

[0010] In a further embodiment, the inner wall of the heat-treated layer is fixedly connected to the outer surface of the core.

[0011] In a further embodiment, the inner wall of the corrosion-resistant layer is fixedly connected to the outer surface of the heat-treated layer.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This device makes the groove of the reinforcement body correspond to the angle of the inner wall of the square tube body. The cooperation of the angle and the groove can prevent the reinforcement body from shifting or rotating during the installation process, thereby ensuring that the reinforcement can be correctly installed at the inner corner of the square tube body. The reinforcement body is then pushed into the square tube body so that it is engaged with the groove. The reinforcement body is then further fixed to the square tube body by the installation block and the fixing pin to prevent it from falling off or moving. The structural strength of the reinforcement body can be increased by cooperating with the plate core through the reinforcement ribs, providing the main strength support for the square tube body, so that the reinforcement can better adapt to complex working environments. At the same time, the heat treatment layer has undergone a heat treatment process to improve the mechanical properties of the plate core. The corrosion-resistant layer arranged on the outside can protect the reinforcement body from external corrosion factors during daily use, thereby improving its reliability and service life.
