Assembled prestressed corbel bracket and its construction method

Abstract

The invention relates to a fabricated prestressed bracket. The fabricated prestressed bracket includes a prestressed system, a bracket prepressing system and an attached-to-pier type transfer platform; the prestressed system includes embedded parts, prestressed tendons, pier columns and bracket bodies; the bracket prepressing system comprises prepressing plates, third steel strands, graded loads and top loads; and the attached-to-pier type transfer platform includes bottom plates, top plates, vertical supports, first steel strands, overhanging profile steel, platforms, second steel strands, ground anchors and wire take-up devices. The fabricated prestressed bracket has the beneficial effects that compared with the prior art, part of the embedded parts are embedded in the pier columns, theother part of T-shaped end plates are exposed to form supporting platforms to be used for supporting the bracket bodies, in addition, tie bar through holes are formed in the embedded parts, and the prestressed tendons can be tensioned through the through holes.

Description

technical field [0001] The invention relates to the field of corbel brackets, in particular to an assembled prestressed corbel bracket and a construction method thereof. Background technique [0002] The corbel bracket refers to the support bracket that is composed of section steel to form a structure similar to the corbel. The corbel bracket is fixed on the side wall of the pier column, and then the platform plate and other components are placed on the corbel bracket to make it stand on the pier column. The sides form a new support plane. At present, most of the corbel brackets are welded into the embedded iron parts in the form of welding. Although this construction method is fast, the bottom of the corbel bracket lacks a supporting platform. Under the action of the upper load, problems are prone to occur at the welding place; In addition, the corbel bracket is used as a supporting component, and its bearing capacity needs to be tested. If the bearing capacity is too low,...

Problems solved by technology

At present, most of the corbel brackets are welded into the embedded iron parts in the form of welding. Although this construction method is fast, the bottom of the corbel bracket lacks a supporting platform. Under the action of the upper load, problems are prone to occur at the welding place; In addition, the corbel bracket is used as a supporting component, and its bearing capacity needs to be tested. If the bearing capacity is too low, it is easy to cause the corbel bracket to be crushed by the upper load during construction, which will eventually cause irreversible consequences, and the load will be directly loaded once. If the load is too large, it is easy to directly crush the corbel bracket under the action of high load, causing construction accidents; because the height of the pier column is generally high, during construction, if there is no stable The platform is for construction workers to stand, and the construction efficiency will be reduced
