Problems solved by technology

With the gradual reduction of steel prices and the pursuit of the ultimate floor height in architectural design, the design tension reinforcement ratio of flexural members is often high, and the bonding of steel or FRP at the bottom of the beam often leads to brittle super-reinforcement of flexural members destroy

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0021] This application can be widely used in the reinforcement and transformation of structures such as buildings and bridges, as well as post-disaster repairs such as earthquakes and fires. The joint work of the beam side steel plate 1 and the main body of the concrete bending member is ensured by the planted reinforcement post-anchoring technology, thereby increasing the stress at the same time. The tension and compression reinforcement of flexural members can maintain or even improve the ductility and deformation capacity of the members while increasing the flexural bearing capacit...

Abstract

The invention relates to a reinforced concrete flexural member with anchor steel for bending strengthening. The reinforced concrete flexural member comprises a component main body and further comprises beam side steel plates and bonded-rebar-type rear anchoring connecting structures. The beam side steel plates are fixed to the side face of the component main body and fixed through the bonded-rebar-type rear anchoring connecting structures. Compared with the prior art, the bonded-rebar-type rear anchoring connecting structures are adopted to transmit shearing force between the beam side steel plates and the component main body, and thus inner force of the steel plates can be directly transmitted to the interior of the concrete component main body. Additionally, anchor bolts have certain shearing deforming capacity, inner force redistribution of the shearing force among the anchor bolts can be achieved, and the stress concentrated phenomenon is avoided.

Description

technical field [0001] The invention relates to a flexural component, in particular to a reinforced concrete flexural component with anchor steel flexural reinforcement. Background technique [0002] The existing reinforcement methods for reinforced concrete flexural members mainly include beam bottom bonding steel or fiber reinforced composite (FRP) method, and the main failure form is brittle peeling failure of the bonding interface. With the gradual reduction of steel prices and the pursuit of the ultimate floor height in architectural design, the design tension reinforcement ratio of flexural members is often high, and the bonding of steel or FRP at the bottom of the beam often leads to brittle super-reinforcement of flexural members destroy. Contents of the invention [0003] The object of the present invention is to provide a reinforced concrete flexural member with anchor steel flexural reinforcement in order to overcome the above-mentioned defects in the prior art...
