Therefore, the manufacturing and binding quality of the steel bars are analyzed and discussed by combining practical experience in work, and the importance of steel bar engineering in building construction is pointed out. The function of the longitudinal steel bar in the frame column: resisting the bending moment effect generated by gravity load and bearing tensile force; resisting the overturning moment effect generated by horizontal load or earthquake horizontal action and bearing tension; the axial compression ratio limit specified by the anti-seismic standard frame anti-seismic construction measures includes that no longitudinal steel bar is used for bearing axial compression. At present, with the increasing number of super high-rise buildings and new capital construction of big data, the strength grade of the steel bar is higher and higher, the diameter of the steel bar is larger and larger, the installation quality of the steel bar is ensured to be more and more difficult, the steel bar has a large straight channel, so the installation risk coefficient is larger and larger, and the installation and fixation are more and more difficult; therefore, the installation and the fixation of the large-diameter column reinforcement are ensured to be particularly important, the reinforcement of the steel reinforcement is required to be controlled, and the installation quality is ensured so as to meet the requirements of design drawings and specifications.
For the rise of the current big data new infrastructure, the earthquake-resistant requirement grade of the data center is one grade, and most of the earthquake-resistant requirement grade is a large-span frame structure, the steel bars of the frame columns are large, the column longitudinal steel bars with the diameter of 32 and the diameter of 36 are achieved, and the longitudinal steel bars root on the foundation of a large bearing platform; the verticality of the installation position of the large-diameter longitudinal steel bar of the frame column is checked and adjusted one by one at present, and the verticality is in a standard requirement range; the platform bearing platform steel bar platform is adjusted to ensure the verticality and position, the steel bar platform can be adjusted and fixed by the traditional welding measure, the risk coefficient is increased after adjustment, the operation is difficult, and the verticality is difficult to control; the verticality adjustment takes time and labor, is not easy to operate, and increases the cost of temporary measures for reinforcing steel bars.
The known reinforcement arrangements for frame posts therefore suffer from the inconveniences and problems described above.
