A AIR-SPRING SUPPORT WITH AIR INJECTOR FOR BEAM

摘要

A strut for supporting a beam by using an air spring with an air injection unit is provided to prevent vibration by injecting the regular amount of air, to construct conveniently by restricting a piston from being displaced, and to contract and expand regularly regardless of temperature change by charging nitrogen. An upper placing part is integrally installed in a height adjusting part in a strut(100) for supporting a beam by using an air spring, and a fitting sill is formed in an upper part of the height adjusting part to fix an upper support bar with a rubber packing as a piston. An air injection part is additionally formed at a side of the height adjusting part to inject compressed air. The air injection part is filled with nitrogen. Vibration of the upper placing part is restricted against impact by injecting air into the air injection part.
