Prefabricated small box girder reinforcing steel bar tire membranization mounting device and method

Abstract

The invention relates to a prefabricated small box girder reinforcing steel bar tire membranization mounting device and method. The device comprises a top plate tire membrane for prefabricating a top plate reinforcing steel bar framework and a web tire membrane for prefabricating a bottom plate and a web reinforcing steel bar framework. The top plate tire membrane comprises a supporting table for erecting top reinforcing steel bars, gratings for allowing top plate reinforcing steel bars to be arranged are arranged on the upper surface of the supporting table, and transverse reinforcing steel bars locating plates are arranged on the two sides of the supporting table and fixedly connected with the supporting table through bolts. The web tire membrane comprises a bottom table arranged on the ground, the two sides of the bottom table are hinged to inclined frames for erecting and abutting against web plate vertical reinforcing steel bars, supporting rods hinged to the inclined frames are arranged on the two sides of the inclined frames, transverse convex rods for erecting web plate horizontal reinforcing steel bars are arranged on the inclined frames towards the inner sides, locating cross rods are arranged at the upper ends of the inclined frames, and locating grooves are formed in the locating cross rods. According to the device and method, a small box girder reinforcing steel bar tire membrane can be fast molded conveniently through the top plate tire membrane and the web tire membrane, and meanwhile the structural stability of the tire membrane is guaranteed through locating mechanisms on all the tire membranes.

Description

technical field [0001] The invention relates to a prefabricated small box girder reinforcing bar membrane-forming installation device and method thereof. Background technique [0002] In road construction, especially in the construction of expressways, it is often necessary to construct bridges or viaducts. In the prior art, the method of prefabricating small box girders is transported to the site for installation by means of transportation, which greatly shortens the construction time. During the working hours, the prefabricated small box girder needs to install the reinforcement film in the mandrel and then pour it into shape. However, the existing prefabricated small box girder reinforcement built-in reinforcement film takes a long time to install, not only the position, height and length of each steel bar need to be adjusted. Only by making accurate settings can the mechanical properties of the final prefabricated small box girder be guaranteed. For this reason, a ...
