Description

Technical Field

[0001] The invention relates to the technical field of steel structure sliding construction, in particular to a ball hinge support filling method used for steel structure sliding construction. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Since steel structures are the heaviest and largest in volume, it is difficult to achieve precise construction through hoisting. They are assembled in an open space and then transported to the designated location by sliding, which requires high construction precision. However, the current sliding construction of steel structures is generally carried out on a track set at the top of the column. After sliding into place, the track is removed, and the distance from the bottom plate of the steel structure support to the top of the column is basically just enough to meet the space required for the installation of the ball joint support, about 20 to 50 mm. In this way, the ball joint support needs to be filled in from the side. Usually, the ball joint support is filled in by tilting and lifting, but because the ball joint support is relatively heavy, tilting and lifting poses certain safety risks.

[0003] Therefore, it is of great practical significance to develop a spherical joint bearing filling method that is easy to operate, does not cause damage to the spherical joint bearing during the operation process, and has good safety. Summary of the Invention

[0004] Due to the above-mentioned defects in the prior art, the present invention provides a ball joint bearing filling method which is convenient to operate, will not cause damage to the ball joint bearing during the operation process and has good safety. Specifically, a movable sliding traction bracket is set at the column head for vertical lifting and horizontal sliding of the ball joint bearing, which is guided and pulled into place by an electric hoist and a fixed pulley. The method is cleverly designed and simple to operate, ensuring that the ball joint bearing is safe and reliable during the positioning process, and solves the defects of the ball joint bearing that is inconvenient to operate and easy to damage the ball joint bearing and has safety hazards due to the crooked pulling and slanting filling.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A ball joint bearing filling method for sliding construction of a steel structure comprises the following steps:

[0007] (1) A traction bracket and a sliding bracket are respectively installed on opposite sides of the steel column, wherein the traction bracket crossbeam in the traction bracket and the sliding bracket crossbeam in the sliding bracket are located on the same straight line, and the sliding bracket is a foldable sliding bracket;

[0008] (2) retracting the sliding bracket so that the sliding bracket is in a retracted state, fixing the ball joint support on the ball joint support lifting system bracket, and moving the ball joint support lifting system bracket to a position to be lifted;

[0009] (3) Install a clamp with an ear plate on the steel structure directly above the position to be lifted, and fix the guide fixed pulley on the ear plate. Fix the fixed end of the electric hand chain hoist to the end of the traction bracket beam away from the sliding bracket. The other end of the electric hand chain hoist is fixed to the wire rope. The wire rope passes through the guide fixed pulley and is fixed to the top of the ball joint support lifting system bracket.

[0010] (4) Turn on the electric hand chain hoist and start to lift the ball joint support lifting system bracket to a certain height, unfold the sliding bracket so that the sliding bracket is in the unfolded state. At this time, the ball joint support lifting system bracket is just located on the sliding bracket beam of the sliding bracket;

[0011] (5) Remove the clamp with ear plate and the guide fixed pulley, and fix the wire rope directly to the spherical hinge support lifting system bracket near the traction bracket;

[0012] (6) Turn on the electric hand hoist to pull the ball joint support lifting system bracket to move on the sliding bracket beam until the ball joint support lifting system bracket reaches the target position of the ball joint support. Finally, remove the ball joint support lifting system bracket to complete the filling operation of the ball joint support.

[0013] The ball joint bearing filling method for steel structure sliding construction of the present invention has a reasonable overall step design, a traction bracket and a foldable sliding bracket are installed on the column head, and a traction device is installed on the traction bracket to realize vertical lifting (in conjunction with the fixed pulley installed on the steel structure) and horizontal sliding of the ball joint bearing. The design is ingenious and the operation is simple. It avoids the conventional installation method of tilting and lifting the ball joint bearing. The whole process will not cause damage to the ball joint bearing (in conjunction with the ball joint bearing lifting system bracket), and the construction process is safe and reliable, with good application prospects.
