Abstract： In this paper， the technical requirements of auxiliary fixing of inner channel steel in elevator shaft are analyzed based on defect cases. By analyzing the requirements of expansion bolt fixing， checking the force of expansion bolt， the transverse and longitudinal fixing methods of channel steel and the welding process of channel steel and guide rail bracket are proposed， conducting a relatively complete process standard of guide rail bracket fixing system from well wall - code support - channel steel - guide rail bracket - guide rail.

Key Words： Elevator; Channel steel; Auxiliary fixing; Guide rail support

1引言

導軌支架是電梯導向系統(tǒng)的基礎結構件，它固定了導軌的空間位置，將整個電梯導向系統(tǒng)的力傳遞到墻體，導軌支架固定的可靠性即為支架與墻體固定可靠程度。（剩余2889字）
