Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Referring to fig. 1 to 7, the anti-cracking structure of the corrugated steel web composite bridge comprises a top plate concrete 5, a bottom plate concrete 6, a corrugated steel web 13 and an asynchronous hanging basket 4, wherein the top plate concrete 5 is located above the corrugated steel web 13, the bottom plate concrete 6 is located below the corrugated steel web 13, and the asynchronous hanging basket 4 is located above the top plate concrete 5, and is characterized in that the anti-cracking structure further comprises a perforated steel plate 3 and an aerated cellular anti-cracking ring 1, the perforated steel plate 3 is located above the corrugated steel web 13, the perforated steel plate 3 is located below the asynchronous hanging basket 4, an opening 31 for fixing the aerated cellular anti-cracking ring is formed in the perforated steel plate 3, the aerated cellular anti-cracking ring 1 comprises an inner ring 11 and a side wing 12, and the side wing 12 is tightly sleeved in the opening 31.
Further, the air-entrapping honeycomb-shaped anti-cracking ring 1 is tightly sleeved in the opening by the side wings 12 by utilizing the self characteristics, and is then reinforced by glue and connected with the opening 31. Effectively preventing concrete from entering.
Furthermore, rubber bubble holes 2 are formed in the aerated honeycomb-shaped anti-cracking ring 1. A synthetic rubber material is used.
The two perforated steel plates 3 are arranged side by side.
The open pores 31 are arranged at equal intervals, and the cellular aerated anti-cracking rings 1 are arranged in the open pores of the open pore steel plate 3 close to the shearing force action position.
The rubber ring 1 is made of synthetic rubber materials, and the perforated steel plate 3 is positioned below the asynchronous hanging basket 4 and plays a role in fixing the asynchronous hanging basket 4; the asynchronous hanging basket 4 is initially positioned on the first block 8, and moves rightwards along with construction progress, so that the asynchronous hanging basket 4 plays a role in pouring the top plate concrete 5 and the bottom plate concrete 6; the asynchronous hanging basket 4 is made of high-strength materials; after the transverse prestress tensioning of the zero block 7 is finished, the first block 8 is constructed; after the transverse prestress tensioning of the first block 8 is finished, the second block 9 is constructed; after the transverse prestress tensioning of the second block 9 is finished, the third block 10 is constructed; the corrugated steel web 13 is positioned on the side surfaces of the first block 8, the second block 9 and the third block 10, and plays a role in bearing the load of the asynchronous cradle 4; the corrugated steel web 13 is made of high-strength material.
In the construction process of the corrugated steel web self-bearing cantilever, after the top plate concrete 5 is poured, the asynchronous hanging basket 4 moves to the right, the bottom plate concrete 6 on the right side is poured, and when the bottom plate concrete 6 is poured, the phenomenon of concentrated shear stress can occur between the concrete (the top plate concrete 5) poured on the upper portion and the end portion of the perforated steel plate 3, so that the concrete is cracked, and the durability and the strength of the structure are influenced. Therefore, the crack-resistant device is additionally arranged in the opening at the end part of the upper poured concrete and the opening steel plate 3. Before the steel bars are installed, the rubber ring 1 is firstly sleeved on the perforated steel plate 3 (the rubber ring is arranged in a hole of the perforated plate group close to the shearing force action position), then the steel bars are installed, and concrete is poured. In the construction process of the self-bearing cantilever of the corrugated steel web, the rubber ring 1 and the bubble holes 2 in the rubber have lower elastic modulus and hardness relative to concrete and steel, the initial shear rigidity of the front-end perforated steel plate 3 can be effectively reduced, and a larger relative slip quantity is generated between the perforated steel plate 3 and the concrete in the early loading stage, so that the shear force can be more uniformly transmitted to the rear perforated steel plate 3. After the rubber ring 1 and the bubble holes 2 in the rubber are fully extruded and deformed, the front opening 31 can continue to bear a certain shearing force, and the phenomenon of shear stress concentration of the front connecting piece is relieved more effectively.
