Embodiment Construction

[0066] Below in conjunction with accompanying drawing and embodiment the invention is described in detail:

[0067] The purpose of the present invention is to provide a high-efficiency fully prestressed composite integrated reinforced reinforced concrete structure technology and method, which can improve the bending capacity of the original concrete structure and improve its deformation performance, and can also be used for components that have been damaged by load. It plays a very good role in repair and reinforcement, and can effectively solve the problems of "strain lag and interface damage" that cannot be completely solved by traditional reinforcement technology, and the reinforcement range can be determined without limitation according to engineering needs, so the practical application range is very wide. Can meet the actual needs of the project.

[0068] In the traditional prestressed reinforcement method, the prestress loss caused by the shrinkage of the tensile prestre...

Abstract

The invention provides a fully prestressed and compositely integrally reinforced concrete structure of adopting a compositely integral dual-measure reinforcing technology of prestress and binding to reinforce a concrete beam, a plate, a column and a joint. The reinforced concrete structure comprises a beam to be reinforced, a stressed area steel plate, a tensile region steel plate, a steel plate hoop, a cable-stayed rebar and a screw, wherein a column structure of the reinforced concrete structure comprises a column to be reinforced, a jack, a welding temporary bracket and at least two groups of reinforcing assemblies; the reinforced concrete column structure comprises the column to be reinforced, a fixing component, a connection steel plate and at least two groups of reinforcing assemblies, and the reinforced concrete cantilever plate structure comprises a cantilever plate extension end to be reinforced, a steel plate strip, an chemical anchor bolt and a fastener, so as to solve essential issues that old and new structures of the known reinforced concrete structure reinforcing technology cannot cooperatively work.

Description

technical field [0001] The invention relates to the field of concrete structure reinforcement, in particular to a fully prestressed composite integrated reinforced reinforced concrete structure. [0002] Background technique [0003] Reinforced concrete structure is the most extensive and large-scale structural form in engineering structures. It is widely used in construction engineering, bridge engineering, port wharf, tunnel engineering and other fields. Concrete buildings will need to be reinforced or repaired due to material deterioration, increased load, accumulated damage, changes in use functions, and initial defects in design and construction. Therefore, the reinforcement and reconstruction technology of reinforced concrete structures has become the key content of the research in the field of structure reinforcement and reconstruction. [0004] my country's "Code for Design of Concrete Structure Reinforcement" (GB50367-2006) proposes a variety of reinforcement met...
