Description

Technical Field

[0001] This utility model relates to the field of building steel structure and steel structure industry, and in particular to a cup-shaped suspended steel column installation process positioning device. Background Technology

[0002] Currently, in the design of steel structure buildings and steel structure industrial plants, there are many ways to connect steel columns to the foundation. Commonly used methods include pre-embedded bolt connection, hinged connection, and cup-shaped foundation connection. Among these, the cup-shaped steel column installation method is frequently used.

[0003] During the manufacturing process in the factory, the steel columns are fabricated as individual components and then transported to the construction site for hoisting and positioning. The steel columns typically use a cup-shaped insert base. After transportation to the construction site, a combination of cranes and manual labor is used to hoist, position, and adjust the elevation of the steel columns.

[0004] Traditional installation methods, also known as industry-standard installation techniques, involve installing steel columns using these methods. Since the steel column has no contact area with the concrete foundation after being inserted into the foundation socket, the following steps are required to complete the installation:

[0005] 1. Remeasure the bottom elevation data of all cup-shaped foundations, and compare the remeasured data with the design elevation value of the column base plate to obtain the actual elevation difference.

[0006] 2. Use steel plates of various thicknesses to adjust the bottom elevation of the cup to match the installation height of the column base plate and re-measure to ensure it passes inspection.

[0007] 3. Use a total station to project the plane coordinates of all steel columns onto the area around the cup opening, and draw installation reference lines at the corresponding positions on the column body.

[0008] 4. Use a crane to insert the steel column into the cup opening, and then use a specially made support iron to fix the steel column to the center of the cup opening from all four sides of the column. Use a horizontal jack to repeatedly adjust the steel column to the installation position from all four sides of the column.

[0009] 5. Remeasure and adjust the elevation of the steel columns. Install four guy ropes at the top of the steel columns and use them to adjust the verticality of the steel columns to within the standard allowable range. Install the remaining steel columns in sequence according to the axis.

[0010] Using traditional construction methods, the hoisting and positioning of steel columns is quite difficult, and usually consumes a lot of auxiliary materials, manpower and resources.
