A quick-mounting steel structure of an elevator shaft

Abstract

The utility model discloses a quick -wearing type steel structure of elevator well, including derrick column, well beam and open type triangular plate connecting piece, open type triangular plate connecting piece is by upper triangular board, lower triangular board and the U -shaped slot part of middle part constitutes, the well beam both ends clamping fixed in the U -shaped slot part, is fixedly connected with derrick column through open type triangular plate connecting piece. Compared with prior art, the utility model discloses open type triangular plate connecting piece and cooperates between derrick column, well beam and connects, can all adopt factory standard spare and accessory prefabricated production, and can be fixed at construction site, effectively solve the precision and quality problem that the traditional on -the -spot size, manual positioning re -welding leads to appears, thereby can effectively shorten construction time, reduce the security hidden danger of on -the -spot operation.
