Structural components of steel gate

The steel gate is mainly composed of two parts, the gate frame and the gate. The sluice frame is the supporting member of the sluice, and also the running slide of the sluice. It is installed and fixed in the second-stage concrete of the sluice pier and the sluice bottom plate by anchor bolts to safely transfer all the water pressure on the sluice to the sluice chamber middle. In order to save materials scientifically and rationally and reduce its own weight, its cross-section is made into a lattice type, and the size of the cross-section is comprehensively considered according to the load and the operating conditions of the gate.

The gate plate of the steel gate is a movable water-retaining member used to close and open the orifice. A cast iron frame beam is set around the plate surface. In order to improve the strength of the steel gate, the plate surface is made into an arch shape, and the central angle of the arch is 60 degrees. Designed to reduce the water pressure on it.

In order to facilitate the manufacture, transportation and installation of steel gate, the gate can be made into upper and lower parts, and then bolted to assemble into a whole after the installation site. The upper and lower plates of the connection are provided with flanges and ribs to make the middle of the gate. The beam is used to improve the longitudinal rigidity of the gate, and longitudinal ribs are arranged in the width direction to improve its lateral rigidity and at the same time play the role of a longitudinal beam.
