U-shaped beam and fabricated track
The invention relates to the technical field of bridge engineering, in particular to a U-shaped beam and an assembly type track. The U-shaped beam comprises a bottom plate, two webs and two upper flange plates; the two webs are connected to the two sides of the bottom plate in the preset direction correspondingly and are symmetrically arranged relative to the bottom plate. The two upper flange plates are connected with the two webs correspondingly and located at the ends, away from the bottom plate, of the webs. Wherein a polyester sound-absorbing cotton layer and a foam metal layer are arranged in the web plate. The U-shaped beam is high in prefabrication degree, the construction period can be shortened, the construction cost is reduced, and the influence on the environment is reduced; in addition, the self weight of the bridge can be reduced, the prestress efficiency is improved, the sound insulation and impact resistance are improved, the stress integrity is higher, and the safety of the structure is improved.
本发明涉及桥梁工程技术领域，具体而言，涉及一种U形梁和装配式轨道。U形梁包括底板、两个腹板以及两个上翼缘板；两个腹板分别连接于底板沿预设方向的两侧，且相对于底板对称设置；两个上翼缘板分别与两个腹板连接，并位于腹板远离底板的一端；其中，腹板内置有聚酯吸音棉层及泡沫金属层。该U形梁的预制装配化程度高，能够缩短施工周期，降低工程造价，以及减小对环境的影响；而且能够使得桥梁自重降低，提高预应力效率，改善隔音和抗冲击性能，受力整体性更强，提高结构的安全性。
