Qualified steel structure standard

　　As one of the hottest building steels, Foshan steel structure has high construction efficiency and short construction period. The construction period saves about 1/3 than traditional cast-in-place building, and its service life is long, and it is generally more than 50 years. After the completion of the construction of the steel structure, the acceptance criteria for the steel structure are also very strict.
1., the backfill is completed around the base; the marking axis and the high accurate and complete reference point.
2., the base top surface should be flat, and the haircuts on the two basic surfaces should be intact.
3., the contact should be smooth and smooth, and the surface of the foundation and the bottom of the column should be tight.
4., check the location axis, the steel structure is installed on the axis and elevation of the building, the size and location of the anchor can be checked and checked.
5., as the anchor bolts, we need to review the axis and elevation of each bolt.
The above is the acceptance criteria for the Foshan steel structure after the handover. The acceptance is very important, and we must not be careless.
