Harmonic Gearbox CSF-32-100-2UH

Harmonaco steel plate cutting harmonic gearbox CSF-32-100-2UH When steel plates are welded into various cross-sectional types (such as I-shaped or box-shaped sections, etc.), thinner steel plates are often used for economic reasons, which requires preventing the flange or web from losing local stability. Welded columns are the same as welded beams. In order to ensure that the flange and web do not lose local stability during normal operation, it is necessary to limit the thickness of the fishing plate or take other trenching measures (such as stiffening ribs, etc.).

Local stability of flange plates of I-section columns

For the local stability of the flange plates of welded I-section columns, it is not appropriate to strengthen them by stiffening ribs, but only by increasing the thickness of the steel plate or reducing the width of the flange.

The function of the foot is to fix the column and transfer its load to the foundation. Since the strength of the concrete foundation is much lower than that of steel, the end of the foot must be enlarged to increase its contact area with the foundation. The column foot is divided into two types according to the connection method between it and the foundation: hinged connection and rigid connection. The former bears axial pressure, while the latter bears axial pressure and bending moment. The column foot is the part of the column that uses more materials and is more labor-intensive, so more attention should be paid to it during design.

In the column foot that is under central compression, part of the pressure is transmitted from the column body to the shoe beam, rib plate or awning plate through the weld, and then to the base plate through the weld connecting them with the base plate, and then to the foundation. The other part is directly transmitted to the base plate through the weld between the column end and the base plate, and then to the foundation.
