Problems solved by technology
When the construction conditions are limited, if the conventional straight-line side-span form is used, it will not be able to adapt to the site construction conditions; if the restricted part is considered separately, the remaining part still adopts a rigid continuous beam structure with a straight-line side span, which needs to be adjusted The span of the main span will be difficult to meet the navigation requirements

Embodiment Construction
[0013] refer to figure 1 , 3 a, b, c, the curved side span 3 and the main span 1 are continuous structures, and both spans are consolidated at the main pier 2, so that the main pier 2 can share the torque transmitted from the curved side span and the curved side span 3 and the main span 1 unbalanced bending moment. The main pier 2 is fixed on the bearing platform 9 .
[0014] refer to Figure 4 , 5 6. A middle partition 4 is arranged inside the curved side span 3 to improve the torsional stiffness of the curved side span 3. A widened torsional beam 5 is arranged in the middle, and a torsional support 6 is arranged under the torsional beam 5. The end of the curved side span 3 is provided with an end partition 7, and the end partition 7 is on the common side support 8.
[0015] The invention has strong adaptability to construction conditions, smooth and beautiful plane line shape, comfortable driving environment, reasonable structural stress, safety and reliability.

The invention discloses a combined structure of a curved bridge antitorque beam and an antitorque support, relating to a curved sidespan structure of a rigid frame continuous beam as well as a structure of the curved sidespan structure and main frusta body connection. The curved sidespan and main span are in a continuous structure, two spans are both fixedly connected with the main frusta on the main frusta, and the main frusta is fixed on a bearing platform; a middle clapboard is arranged in the curved sidespan, and the middle is provided with the antitorque beam; the antitorque support is distributed below the antitorque beam; and the end part of the curved sidespan is provided with an end clapboard which is fixed on a common side support. The invention adopts the curved sidespan rigid frame continuous beam, is flexible, novel and beautiful, has strong applicability, smooth horizontal alignment, clear mechanical properties, specific function of each member, safe and reliable construction and continuous and simple structure system. The invention provides a comfortable environment for travelling, and is suitable for the situation that bridge line shape obeys road line shape and the situation that navigation and construction sites are confined.
Description
technical field [0001] The invention relates to a curved side span structure of a large-span rigid frame continuous beam, and a connection structure with a main span and a main pier body. Background technique [0002] In the past two decades, my country's bridge technology has developed rapidly. Rigid frame continuous girder bridges have been widely used and developed in highway bridge construction due to their mature technology and reasonable cost. The construction environment has strong adaptability and has been widely used and developed. [0003] Long-span rigid-frame continuous girder bridges can provide a safe and comfortable driving environment. Usually, the side spans are in the form of a straight line. This structural form has clear mechanical properties, but it has high requirements for construction conditions. When the construction conditions are limited, if the conventional straight-line side-span form is used, it will not be able to adapt to the site construction...
