Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Referring to fig. 1 to 7, a corrugated steel web bridge spherical anti-crack device comprises a corrugated steel web 13, an asynchronous cradle 4, a zero block 7, a first block 8, a second block 9 and a third block 10, wherein the zero block 7, the first block 8, the second block 9 and the third block 10 are arranged from left to right, 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, the asynchronous cradle 4 is initially positioned on the first block 8, the spherical anti-crack device further comprises a perforated steel plate 3 and a rubber ball 1, the perforated steel plate 3 is fixed below the asynchronous cradle 4, an opening 31 for fixing the rubber ball is formed in the perforated steel plate 3, the rubber ball 1 comprises an inner ring clamping groove 11 and two side wings 12, an inner ring clamping groove 11 is formed between the upper side wing 12 and the lower side wing 12, the rubber ball 1 is clamped on the opening 31 by the inner ring clamping groove 11, the rubber ball 1 is provided with a reinforcing steel bar hole 2 used for crossing a reinforcing steel bar.
Furthermore, the reinforcing steel bar hole 2 is formed in the rubber ball, penetrates through the whole rubber ball 1, and is perpendicular to the center of the groove of the inner ring clamping groove 11.
Still further, there are two perforated steel plates 3, which are arranged side by side.
The holes 31 are arranged at equal intervals, and the rubber balls 1 are arranged in the holes of the perforated steel plate 3 close to the shearing action position.
The spherical anti-cracking device further comprises top plate concrete 5 and bottom plate concrete 6, 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.
The rubber ball 1 is made of flexible materials such as rubber, the rubber ball 1 is clamped on the perforated steel plate 3 through a side clamping groove to prevent displacement, and then is fixed through glue to prevent concrete from entering; 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; the zero block 7 is a basic structure of the whole project; 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 this embodiment, in the construction process of the corrugated steel web self-supporting cantilever, after the top plate concrete 5 is poured, the asynchronous hanging basket 4 moves to the right, and the bottom plate concrete 6 on the right side is poured, and when the bottom plate concrete 6 is poured, the phenomenon of shear stress concentration 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 cracks, and the durability and strength of the structure are affected. 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 installing the steel bars, the rubber balls 1 are fixed on the perforated steel plates 3 (the rubber balls are arranged in holes of the perforated plate group close to the shearing action position), then the steel bar mesh is installed, and concrete is poured. In the construction process of the self-bearing cantilever with the corrugated steel web plate, the rubber ball 1 has 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 at the early loading stage, so that the shear force can be more uniformly transmitted to the rear perforated steel plate 3. After the rubber ball 1 is fully extruded and deformed, the front opening 31 can continuously bear a certain shearing force, and the phenomenon of shear stress concentration of the front connecting piece is relieved more effectively.
