AI Technical Summary

Technical Problem

In existing technologies, the stability of steel box girder during hoisting is affected by the external environment, making it difficult to align the installation slot with the positioning slot, which takes a long time.

Method used

The design incorporates a limiting groove, a limiting plate, and a guide ramp. The limiting plate is inserted into the limiting groove for positioning, and the guide ramp provides guidance. Combined with the crossbar and clearance groove, the lifting weight is distributed to avoid localized stress concentration.

Benefits of technology

It reduces the impact of the external environment during connection, improves the ease of aligning the mounting slot and positioning slot, reduces installation time, and avoids deformation by dispersing gravity through the crossbar.

Abstract

The utility model discloses a spliced steel box girder structure, the utility model discloses a top plate, the both ends fixed with side board of top plate bottom outer wall, two side board bottom end is connected with same bottom plate, the outer wall of one end of top plate and bottom plate all is fixed with limit plate, the other end of top plate and bottom plate all is seted up with limit slot, and the both sides of limit slot one end are provided with guide slope, and the one end of guide slope is inclined to the one end of limit slot away, the limit plate of top plate one end is vertical with the limit slot of bottom plate one end, the outer wall of top plate bottom is fixedly connected with a plurality of parallel arrangement's vertical baffle and cross baffle, and the other end of vertical baffle and cross baffle all are connected with bottom plate and side board, the utility model discloses a limit slot, limit plate and guide slope are set up, and when connecting, limit plate is inserted into limit slot and is positioned, avoids the stable due to hoisting and is influenced by external environment, and thus the alignment of mounting groove and positioning groove is difficult to operate, and the time -consuming is longer.
