Obliquely-arranged bridge support system
The invention relates to an obliquely-arranged bridge support system. The system comprises a main beam, an embedded steel plate, a support, a support padstone and a pier, wherein the support padstone is installed on the pier, and the obliquely-arranged bridge support system is characterized in that the pier is obliquely arranged, a beam bottom wedge block is integrally poured at the bottom of the main beam, and the embedded steel plate is partially poured on the beam bottom wedge block; the embedded steel plate is fastened on an upper support steel plate in the support through a first fastener, and a lower support steel plate in the support is fastened on the support padstone through a second fastener. In the bridge support system provided by the invention, the upper load vertically acts on the top of the pier through the support, so that the pier only generates axial force under the action of symmetrical load, and the support which is transversely, symmetrically and obliquely arranged under unbalanced stress can also self-balance most tangential force, so overlarge shearing force and bending moment are prevented from being generated on the pier, therefore, the bridge support system provided by the invention has advantages of being high in structural adaptive capacity and self-balanced in dynamic stress.
本发明涉及一种倾斜布置的桥梁支座体系，包括主梁、预埋钢板、支座、支座垫石及桥墩，支座垫石安装于桥墩上，具有这样的特征，桥墩呈倾斜设置，且主梁的底部一体浇筑有梁底楔形块，预埋钢板部分浇筑于梁底楔形块上，预埋钢板通过第一紧固件紧固于支座中的上支座钢板上，支座中的下支座钢板通过第二紧固件紧固于支座垫石上。本发明提供的桥梁支座体系中由于上部荷载通过支座垂直作用在桥墩顶部，使得桥墩在对称荷载作用下仅产生轴力，即使在非均衡受力下呈横向对称倾斜布置的支座也可自平衡绝大部分切向力，从而避免在桥墩上产生过大剪力和弯矩，从而使得本发明提供的桥梁支座体系具有结构自适应能力强、动态受力自平衡的优点。
