Description

Technical Field

[0001] The utility model relates to the field of column anti-dropping devices, in particular to a column anti-dropping structure for steel structure construction. Background Art

[0002] During the construction process, compared with reinforced concrete, steel structures have higher strength and better earthquake resistance, and the required steel structures can be manufactured in advance, greatly reducing the construction period. Usually, when the prefabricated columns are fixed to the embedded structures on the cast base, in order to prevent the deformation of the embedded structures from separating from the columns, the columns need to be kept in a suspended state, resulting in low installation efficiency.

[0003] The patent with announcement number CN217630458U discloses an anti-slip structure for steel structure construction columns. The reinforcing rib groove is fixed on the top of the base plate, and the inside of the groove of the reinforcing rib groove is interlocked with the column body. The fixing bolts are cast in the concrete base, and the top passes through the base plate. During installation, the column is lifted and aligned with the slot hole. The first step of fixing is performed through the anti-slip ring, and then the nut is tightened. During the column installation process, the fixing bolts are pre-cast in the concrete base. Due to the deviation generated during pre-setting or the unknown offset of the concrete pouring and solidification, the fixing bolts may be misplaced, which will cause the limit plate of the base plate and the fixing bolts to be unable to adapt, and then the anti-slip ring and the nut lose the fixing effect between the base plate and the fixing bolts, which leads to rework and reduces the efficiency of construction.

[0004] In view of this, during the column construction process, how to achieve a stable connection between the base plate and the concrete base and improve construction efficiency have become technical problems that technical personnel in this field urgently need to solve. Utility Model Content
