Foundation embedding of steel structure construction

 

First, measure the line during the construction of the steel structure.

1. According to the design requirements, compare the picture of the civil engineering unit to check the elevation and axis accurate;

2. Before construction, use the axis and elevation of the latitude and weft meter or a level instrument. Use a marker or ink line as a mark, indicate the elevation, and make a record;

3. Determine the connection surface and axis of each steel column on the basics;

4. Try to avoid the collision between the steel column and the bolt and avoid deformation of the bottom of the column. Reduce the bending deformation of the contact surface with the foundation and the bolt, resulting in unnecessary losses;

5. The measurement of the line is accurate, and the pile base is solid and accurate. Those who cause the materials and rework caused by errors will bear all responsibilities by the responsible person, and a minimum deduction of 200 RMB at a time.

Pay attention to the error during the construction of the construction line, and try to use the latitude and weft as much as possible during the launch process. Don't put the line in the event of a strong wind. Due to different construction levels, there will be errors every time. In order to reduce the error, put the line on both sides of the gables, and then measure it with a steel ruler. If there are errors and drawings in the gable line, it means that the entity does not match the drawings. In the case of inconsistent, it is necessary to correct it in time, reduce the error to the minimum, and control it between 2mm as much as possible.

2. Foundation embedding

1. Before the foundation concrete pouring, carefully check the size, length, high range and location of the bolt, and fix the embedded bolt;

2. Before pouring, bolts should be wrapped in plastic film to prevent the pollution of the bolt wire when pouring;

3. When pouring concrete, professionals should be sent for duty. The effect of the positioning of the bolt when pouring is done to avoid changes in the displacement and elevation of the embedded parts;

4. After the concrete is poured, the residue concrete on the bolt and the wire should be cleaned in time.
