Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated steel columns, and particularly relates to a prefabricated steel column and a connection structure of the steel column. Background Art

[0002] Steel columns are the main load-bearing members in building structures. They mainly bear pressure and sometimes bear bending moments at the same time. The cross-sectional forms of steel columns are diverse, including square columns, circular columns, tubular columns, rectangular columns, I-shaped columns, H-shaped columns, T-shaped columns, L-shaped columns, cross-shaped columns, double-leg columns, lattice columns, etc. The design of steel columns and their connection structures also needs to consider various factors, including ground conditions, load magnitudes, the height and layout of the overall structure, etc. The design and selection of steel columns and their connection structures are crucial for ensuring the structural safety, stability, and seismic performance of buildings.

[0003] Chinese Patent CN115306026A proposes a prefabricated steel column and a connection structure of the steel column, including a first steel column, a second steel column, and a connection cylinder. The connection cylinder is located between the first steel column and the second steel column. Stay ropes are connected between the connection cylinder and the first steel column and the second steel column. Positioning grooves are evenly opened inside the connection cylinder, and through holes are evenly opened on the surface of the connection cylinder. Sleeves are symmetrically arranged inside the connection cylinder. Screws are symmetrically sleeved inside the sleeves. A top plate is fixedly installed at the outer end of the screw. A collar is sleeved outside the overall structure composed of the connection cylinder, the screw, and the top plate. Baffles are symmetrically installed on both sides of the collar. A magnetic ring is sleeved outside the connection cylinder. A grip block is fixedly installed on the surface of the magnetic ring. Both the first steel column and the second steel column are square tube structures. The magnetic ring is made of an electromagnet and can rotate and cooperate outside the connection cylinder, which can adjust the position of the sleeve and is also convenient for adjusting the direction of the sleeve and the direction of the top plate. By setting the baffle, it plays a role of blocking and limiting to prevent the top plate from shaking. Through the setting of the top plate and the connection between the screw and the sleeve, a wrench can be used to adjust the top plate to push the connection cylinder, so as to facilitate supporting the connection cylinder inside the steel column and connecting the steel columns. It replaces the traditional welding method and is equivalent to a fastener arranged between the steel columns, thereby realizing the stable connection of the steel columns. By setting the positioning groove, the position of the sleeve can be positioned.

[0004] The above solution can support the connection cylinder inside by adjusting the top plate, tighten the connection cylinder inside the steel column, and achieve the stable connection of the steel columns, replacing the traditional welding method to stably connect the steel columns. However, the above solution cannot detect the connection firmness between the steel columns, so that the staff cannot know and take measures in time when the connection of the steel columns becomes loose, which will affect the use safety of the prefabricated steel column and the connection structure of the steel column.
