Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, and more specifically, to a metal steel structure connector for highway bridges. Background Art

[0002] Metal steel connectors play a crucial role in highway bridges. These connectors not only ensure the stability of the steel structure but also enhance the overall performance and safety of the bridge. Their use significantly increases the bridge's load-bearing capacity. Through rational connection design and the use of high-strength connectors, bridges can maintain structural integrity and stability even when subjected to heavy loads.

[0003] A search revealed that among the existing published technical literature, Chinese Patent Publication No. CN116815925A discloses a steel structure connector. This connector primarily addresses the problem that steel structures require segmented steel sections to be connected, requiring connectors to connect sections in various directions. Furthermore, the steel structure also requires inclined sections to support it. If the connecting parts on the connector cannot be rotated to adjust the angle, the connector cannot connect to the inclined sections, and thus cannot support the entire steel structure. However, this technology still has the following drawbacks.

[0004] When metal steel structure connectors for highway bridges are used for docking, although the docking positions can be docked, during the docking process, due to the presence of multiple docking points in the metal steel structure connectors for highway bridges, it is difficult to achieve multi-point rapid positioning and connection, which leads to low connection efficiency of the metal steel structure. For this reason, a metal steel structure connector for highway bridges is needed. Utility Model Content

[0009] When in use according to the above technical solution, the sleeve drives multiple positioning plates to be positioned on the outer wall of the steel structure base. At the same time, the sleeve is positioned and plugged along the positioning blocks, and the positioning strips support the guide blocks. The support ring limits the multiple sleeves, so that the sleeve pressure ring is inserted into the outer walls of the multiple positioning blocks, achieving multi-point positioning operation for the sleeve pressure ring. The extrusion nut and the fixed screw move downward under the action of the thread transmission force, and the sleeve pressure ring and the sleeve are firmly connected, which can achieve multi-point positioning connection and higher connection efficiency.

[0010] Preferably, a protective assembly is installed on the outer wall of the extrusion nut; the protective assembly includes a sealing ring fixedly installed on the outer wall of the extrusion nut, and a guide ring is fixedly connected to the upper surface of the sealing ring, and a guide plate is rotatably connected to the outer wall of the guide ring, and a shielding ring is fixedly installed on the lower surface of the guide plate;

[0012] According to the above technical solution, when in use, the extrusion nut drives the sealing ring to rotate synchronously, and the outer wall of the guide ring is squeezed into contact with the inner wall of the guide plate. When external rainwater or other water flow contacts the upper surface of the extrusion nut, the sealing ring guides the water to the guide ring, and the guide ring guides the water to the upper surface of the guide plate.
