Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel component docking device for steel structure construction. Background Technology

[0002] Steel structures are widely used in building construction. As the main vertical load-bearing components, the quality of on-site installation and splicing of steel columns directly affects the overall structural safety. A common technical approach in on-site steel column splicing is to pre-weld temporary lugs near the joint of the upper and lower steel column sections, and then temporarily fix these lugs using connecting clamps and high-strength bolts. This achieves precise alignment and temporary fixation of the steel columns, creating conditions for subsequent formal welding.

[0003] The aforementioned existing technologies have shortcomings in practical applications: the connecting plates used are usually steel plates of fixed length, which can only be adapted to ear plates with specific spacing. When the cross-sectional dimensions of the steel column change, there are construction errors in the welding position of the ear plates, or different projects need to be used, the fixed-length plates are often unsuitable, resulting in the need to equip the site with plates of various specifications. This not only increases material costs and management difficulty, but also requires on-site cutting and modification when the dimensions do not match, reducing construction efficiency.

[0004] In the existing technology, there are some solutions that attempt to improve the ease of steel component docking. For example, Chinese utility model patent CN219767211U discloses a steel component docking assembly, which includes a first plate, a second plate, and a docking device. It adapts to different widths by setting relatively sliding plates one and two, and uses a threaded rod to drive the clamping plates to move, thereby clamping both sides of the I-beam. While this device improves clamping stability to some extent, the clamping plates themselves are still of fixed length, and the adjustment capability depends on the relative sliding between the plates. For the paired ear plates commonly used in steel column docking, which are pre-welded to the column body, the clamping plate length cannot flexibly adapt to different ear plate spacings, and its versatility remains limited. Furthermore, the device has a relatively complex structure, including multiple components such as a hollow sleeve, sliding rod, push block, and auxiliary storage device, which makes installation and operation in high-altitude work environments inconvenient.

[0005] Therefore, considering the characteristics of steel column butt joint construction, a new type of butt joint device is designed with a simpler structure, more direct adjustment, and especially flexible adaptation to different ear plate spacings, in order to solve the problems of poor adaptability of clamping plates, low construction efficiency, and potential damage to the parent material in the existing technology.

Then, the bolts are passed through the No. 1 A round holes and the No. 2 B round holes and threadedly connected to the nuts, thereby completing the fixation of the No. 1 ear plate and the No. 2 ear plate and improving flexibility.

The first fixed plate is fixed to the outer plate; the lead screw passes through the first fixed plate and is rotatably connected to it; the rotating block is fixed to the top of the lead screw; the second fixed plate is fixed to the outer plate; wherein, the bottom end of the lead screw is rotatably connected to one end of the second fixed plate via the bearing, and the lead screw passes through a convex plate and is threadedly connected to it; the operator rotates the lead screw using the rotating block, and because the convex plate is threadedly connected to the lead screw, the convex plate, through the cooperation of the strip-shaped opening, drives the inner plate to adjust its position, improving flexibility.

[0010] Preferably, it also includes a protective frame, which is provided between the first fixing plate and the second fixing plate; the protective frame provides safety protection for the lead screw, reduces the impact and deformation of the lead screw by external objects, and improves its service life.
