AI Technical Summary

Technical Problem

The traditional integrated single-column slide boots lead to a high overall height of the bridge during the installation of steel structure bridges, which is not conducive to shipment and transportation. It has a long production cycle, is not versatile, and has poor lateral stiffness and overall stability.

Method used

The sliding shoe bracket is adopted for the separation type, including the base, track, upper sliding shoe and lower sliding shoe. The sliding shoe bracket is assembled by the upper and lower parts, and the upper sliding shoe is leveled to facilitate the formation of a self-stabilizing system during bridge processing and transportation.

Benefits of technology

The loading height of the bridge is reduced, the height limit constraints are reduced, the transportation efficiency is improved, the production cycle is shortened, the versatility and overall stability of the sliding boot bracket are improved, and the shape stability of the bridge is ensured during the slippage.

Abstract

The invention provides a construction method for adjusting the linearity of a bridge, which adopts a separate assembly shoe bracket, and the separate assembly shoe bracket comprises: a base; a track, which is arranged on the top surface of the base, and the track guides the installation position of the bridge; a lower shoe, which is slidably arranged on the track; an upper shoe, which is used to connect with the bridge, and after the upper shoe and the bridge are moved to above the lower shoe, the upper shoe can be fixed with the lower shoe to slide through the track; the construction method for adjusting the linearity of the bridge comprises the following steps: S1: fixing the base and the track according to the moving position of the bridge; S2: installing the lower shoe on the track at the starting position of the bridge sliding; S3: connecting the upper shoe to the bottom plate of the bridge; S4: transporting to the starting position of sliding, fixing the upper shoe with the lower shoe; S5: sliding the bridge on the track to the installation position; S6: lifting the lower shoe to raise the bridge to a set height. The invention is convenient for transportation and assembly by separating the lower shoe and the upper shoe.
