Description

Sliding Joint Type Steel Beam-Column Joint Structure and Joining Method Using the Same The present invention relates to a sliding fastening type steel beam-column joint structure and a joining method using the same. More specifically, it relates to a sliding fastening type steel beam-column joint structure and a joining method using the same that enables joining without a separate bracket, thereby improving economic efficiency and workability. Generally, since steel structures are fabricated by assembling columns and beams using bolted and welded connections of structural steel, steel plates, and flat plates, the stability of the connections is critical, and the shape of the connections influences the entire design and construction process. Meanwhile, representative connection methods used for such steel structures include bolted connections and welded connections. When beams are added to existing steel structures for reinforcement purposes, bolted connections are preferred in terms of constructability. However, for the connection between columns and beams, moment connections are advantageous in terms of force or stress transfer. While connections requiring moment connections were typically handled using welded or bolted connections, welded connections are disadvantageous in terms of constructability and cost-effectiveness, and can cause deformation of the base material due to welding heat and make on-site quality control difficult. Conversely, although bolted connections are advantageous in terms of constructability, they can lead to significant deformation and loosening of the bolts when subjected to vibration, impact, or repetitive loads. In addition, T-shaped steel or steel plates are frequently used as beams connected to columns; however, using these materials can lead to plastic hinges at the joints, potentially weakening seismic structural performance. Furthermore, in the case of T-shaped steel, there is the inconvenience of having to cut it to size, which results in longer construction times and increased costs. Therefore, conventional steel beam-column joint structures require not only separate brackets and connecting plates but also a large number of fastening bolts to connect them. Consequently, economic efficiency is reduced due to increased material volume, stacking limitations caused by bracket size, and the resulting increase in costs. Furthermore, workability is degraded due to increased working time and inconvenience associated with fastening brackets using bolts. Accordingly, there is a need for a sliding-fastening steel beam-column joint structure that enables joining without separate brackets, thereby improving economic efficiency and workability by reducing the number of bolts and allowing joining without the use of additional connecting steel plates, as well as a joining method using the same.
