A movable bridge deck panel installation platform and method of construction

By designing a movable bridge deck installation platform, and using steel plates and angle steel legs to support the load-bearing components of the steel beams, direct contact between the crawler crane and the bridge deck is avoided. This solves the problems of bridge deck cracking and uneven stress on the steel beams caused by crawler crane installation, and achieves safe and efficient bridge deck construction.

AI Technical Summary

Technical Problem

When tracked cranes install bridge decks, it can easily lead to cracking of the bridge decks and uneven stress on the steel beams, which may cause structural damage.

Method used

Design a movable bridge deck installation platform that uses steel plate legs and angle steel legs to support the main load-bearing components of the steel beam, avoiding direct contact between the crawler crane and the bridge deck. The steel plates bear the load of the crawler crane, allowing the bridge deck to be installed piece by piece and the platform to be moved cyclically.

Benefits of technology

It effectively prevents bridge deck cracking, ensures the safety of steel beam structures, improves construction efficiency and economy, reduces construction space occupation, and enables fast and convenient bridge deck installation.

Abstract

The application discloses a movable bridge deck panel installation platform and a construction method thereof. The movable bridge deck panel installation platform comprises a steel plate leg, an angle steel leg and a steel panel, is installed on the upper side of a bridge deck panel, the steel plate leg and the angle steel leg are supported on a main force component of a steel beam, load is transmitted to the main force component of the steel beam, the safety of the steel beam structure is ensured, a caterpillar crane is moved to the steel panel to perform hoisting operation, direct contact with the bridge deck panel is avoided, bridge deck panel cracking is avoided, compared with a traditional automobile crane or a special frame plate machine, the efficiency is higher and the economy is better, through a construction method of cyclically adopting a hoisting bridge deck panel, installing the movable bridge deck panel installation platform, moving the caterpillar crane to the installation platform, hoisting the next bridge deck panel, space occupation of a construction site is less, and the construction method has the advantages of convenient construction, rapidness, convenience, safety and the like.
