Fabricated bridge
The invention relates to the technical field of bridges, in particular to a fabricated bridge which comprises a first bridge section and a second bridge section, a gap is formed between the first bridge section and the second bridge section, and a fixing unit used for fixing the first bridge section and the second bridge section is installed between the first bridge section and the second bridge section. Each fixing unit comprises a first connecting rod and a second connecting rod which are rotationally connected, third connecting rods are rotationally connected among the first connecting rod, the second connecting rod and the first bridge section, fourth connecting rods are rotationally connected among the first connecting rod, the second connecting rod and the second bridge section, and rotating shafts of the third connecting rods define an isosceles trapezoid. A fifth connecting rod is rotatably connected between the first connecting rod and the second connecting rod, the first connecting rod and the second connecting rod are made of the same material, and the coefficient of thermal expansion of the fifth connecting rod and the coefficient of thermal expansion of the first connecting rod are different.
本发明涉及桥梁技术领域，具体为一种装配式桥梁，包括第一桥梁段、第二桥梁段，第一桥梁段与第二桥梁段之间有间隙，第一桥梁段与第二桥梁段之间安装用于第一桥梁段与第二桥梁段相固定的固定单元，各固定单元包括第一连杆、第二连杆，第一连杆与第二连杆转动连接，第一连杆、第二连杆与第一桥梁段之间转动连接第三连杆，第一连杆、第二连杆与第二桥梁段之间转动连接第四连杆，各第三连杆的转动轴围成等腰梯形，各第四连杆的转动轴围成等腰梯形，第一连杆与第二连杆之间转动连接第五连杆，第一连杆与第二连杆的材质相同，各第五连杆与第一连杆的热膨胀系数不一，本发明减小各桥梁段固定后因热胀冷缩所产生的影响。
