Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and in particular to a clamping device suitable for fixing curved steel columns. Background Technology

[0002] In modern sculptural architecture, curved steel columns are increasingly widely used in pursuit of unique architectural aesthetics. However, traditional construction methods often present numerous challenges when fixing and adjusting these irregularly shaped steel columns. Conventional rectangular or circular clamps, due to their rigid structure and planar contact characteristics, struggle to achieve a full and tight fit with the complex curves of curved steel columns. This mismatch leads to several prominent problems: First, the small contact area results in concentrated pressure during tightening, easily causing localized plastic deformation on the steel column surface, damaging the base material and even destroying its anti-corrosion and fire-retardant coating. Second, gaps exist between the clamp and the column, resulting in insecure fixing, making it prone to slippage, rotation, or overturning during hoisting, alignment, or subsequent construction, severely affecting the accuracy and efficiency of installation positioning. Third, traditional clamp devices often lack convenient and effective adjustment mechanisms, making them difficult to adapt to curved steel columns with different radii of curvature or cross-sectional dimensions, exhibiting poor versatility.

[0003] Therefore, there is an urgent need in the existing technology for a specialized clamping device that can tightly fit the surface of curved steel columns, distribute force evenly, is easy to operate, and has strong versatility, in order to solve the aforementioned technical problems. Therefore, to address the above issues, a clamping device suitable for fixing curved steel columns is proposed to solve these problems. Summary of the Invention

This invention enables the relative fixing of three curved steel columns, improving installation accuracy and efficiency.

[0009] Preferably, each end of the arc-shaped plate is provided with a connecting plate; each connecting plate is provided with four fastener through holes.

[0010] Preferably, the structural dimensions of the double-ear connector are adapted to the connecting plate. When the two are mated together, the through hole and the fastener through hole are coaxially aligned and form a through channel through which the fastening bolt passes without interference.

[0011] Preferably, by tightening the fastening bolts, the arc-shaped plate and the curved support plate work together on the outer wall of the arc-shaped steel column to form a clamping and fixing.
