Triangle hanging basket suspended casting device used for overpass bridge construction and construction method thereof

Abstract

The invention discloses a triangle hanging basket suspended casting device used for overpass bridge construction and a construction method thereof. The triangle hanging basket suspended casting device comprises an anchoring triangular bracket, a bracket platform, a bottom bracket member, a lifting anchoring member, a travelling member and a template system, wherein the anchoring triangular bracket comprises a plurality of triangular supports; one straight edge of the anchoring triangular bracket is used for being anchored on the side surface of a bridge's main pier body through anchor ribs, and the other straight edge of the anchoring triangular bracket horizontally extends forwards in the direction away from the side surface of the bridge's main pier body; the plurality of triangular supports are arranged at intervals in parallel; the anchoring triangular bracket further comprises supporting corbels arranged below the triangular supports and used for jacking and supporting of the bottoms of the triangular supports; the supporting corbels are connected onto the bridge's main pier body through anchor ribs; the bracket support is used for bearing the gravity of other members; the lifting anchoring member is connected with each of the bracket platform and the bottom bracket member; the travelling member is used for the other members to walk thereon; the template system is used for bridge casting. The triangle hanging basket suspended casting device has the advantages of less assembly nodes, definite stressing and high member turnover rate.

Description

technical field [0001] The invention relates to a triangular hanging basket method suspension pouring device and a construction method for the construction of an overpass bridge. Background technique [0002] The cantilever casting method refers to the construction method in which working platforms are set on both sides of the bridge pier, and the cement concrete beam is cantilevered section by section to the mid-span in a balanced manner, and prestressed section by section is applied. The main equipment of the cantilever casting method is a pair of hanging baskets that can walk. The hanging baskets move on the beam section that has been tensioned and anchored and integrated with the pier body. Binding steel bars, erecting formwork, pouring concrete, and applying prestress are all on it. conduct. After the construction of this section is completed, the hanging baskets move forward one section symmetrically to carry out the construction of the next pair of beam sections, and...

AI Technical Summary

Problems solved by technology

[0003] The existing hanging basket method cantilever casting device has many assembly nodes, and it is inconvenient for workers to carry out construction at high altitudes. It requires a lot of man-hours for installation and disassembly, which delays the construction progress and reduces the turnover rate of components.
