The invention discloses a concrete box girder applying refrigeration stirrups, which comprises a box girder, an evaporation pipe, a water inlet pipe and a water removal assembly, and is characterizedin that multiple steel bars are arranged in the circumferential direction of the box girder; the evaporation pipe is connected to the outer sides of the multiple steel bars in a surrounding mode, theinput end of the evaporation pipe is higher than the output end of the evaporation pipe; the output end of the water inlet pipe is connected with the input end of the evaporation pipe, and the water inlet pipe is connected with a three-way valve; the water removal assembly is provided with a water seal cavity, the output end of the evaporation pipe is connected with the water seal cavity through arecovery pipe, the water seal cavity is connected with a first pipeline, the first pipeline extends upwards and is communicated with the input end of the evaporation pipe, the first pipeline and theevaporation pipe are combined for hooping connection of the steel bars, and the lower end of the first pipeline is connected with a molecular sieve. According to the concrete box girder applying the refrigeration stirrups, the structure is cooled through the evaporation pipe type stirrups, the temperature difference stress is effectively reduced, it is guaranteed that the bearing capacity of the box girder meets the requirement, and the service life is prolonged.
本发明公开了一种应用制冷箍筋的混凝土箱梁，包括箱梁、蒸发管、进水管和除水组件，箱梁周向设置有多个钢筋；蒸发管围绕连接在多个钢筋的外侧，蒸发管的输入端高于蒸发管的输出端；进水管的输出端连接蒸发管的输入端，进水管上连接有三通阀；除水组件具有水密封腔，蒸发管的输出端通过回收管连接水密封腔，水密封腔连接有第一管道，第一管道向上延伸并连通蒸发管的输入端，第一管道与蒸发管组合用于箍紧连接钢筋，第一管道的下端连接有分子筛。本发明的一种应用制冷箍筋的混凝土箱梁通过蒸发管式箍筋对结构进行降温，有效减小温差应力，保证箱梁的承载力满足要求，延长使用寿命。
