Description
Technical Field
[0001] The present application relates to the technical field of steel bar connectors, and in particular to a multi-purpose connector for steel bars and glass fiber bars. Background Art
[0002] In urban areas, especially in the city center, soil nail wall support and pile anchor support are commonly used and are also relatively economical support methods. Since the anchor rods are constructed outwards, some even far exceed the land red line, in order to avoid affecting the subsequent underground projects outside the red line, the foundation pits in the city center are often not allowed to directly use steel anchor rods or steel strands.
[0003] Because glass fiber reinforcement has good tensile properties and is easier to cut or break later, the impact of anchor rods using glass fiber reinforcement on later peripheral construction is greatly reduced. Connectors in related technologies are generally used to connect two steel bars. Therefore, how to connect glass fiber reinforcement with steel bars for easy use is a problem that needs to be solved.
