Abstract
The utility model discloses a prestress assembly type concrete beam which comprises a rectangular concrete beam, wherein a threaded reinforcing steel bar is fixedly connected inside the rectangular concrete beam, a groove is formed in the rectangular concrete beam, a sliding plate is connected inside the groove in a sliding mode, threaded holes are formed in the outer surface of the sliding plate, and bolts are arranged inside the rectangular concrete beam. According to the structure, the deformed steel bars are prevented from being bent through the protection of the sliding plate on the deformed steel bars, and meanwhile, the bending resistance of the rectangular concrete beam can be increased after the installation is completed.
Description
Technical Field
The utility model relates to the technical field of concrete beams, in particular to a prestressed assembled concrete beam.
Background
The recycled concrete has been widely used in practical engineering worldwide, and the basic performance of the recycled concrete has been studied deeply, so the recycled concrete is mainly applied to roads and various structure cushions, the recycled concrete beam is a beam made of waste concrete as recycled aggregate, can be used as a basic bearing member in engineering structures such as house buildings, bridge buildings and the like, but is easy to cause deformed reinforcing bars in the processes of hoisting and transportation, the technical proposal provided by the utility model with the application number of CN202221380028.9 is found to have the same problems after searching.
Disclosure of Invention
The utility model aims to at least solve one of the technical problems in the prior art, and provides a prestress assembly type concrete beam, which can prevent the deformed steel bars from bending through the protection of sliding plates on the deformed steel bars and can increase the bending resistance of the rectangular concrete beam after the installation is completed.
In order to achieve the above object, the present utility model further provides a prestressed fabricated concrete girder having the above structure, comprising:
the inside fixedly connected with twisted steel of rectangle concrete beam, the inside of rectangle concrete beam is provided with the recess, the inside sliding connection of recess has the sliding plate, the surface of sliding plate is provided with the screw hole, the inside of rectangle concrete beam is provided with the bolt.
