Steel panel for bridge and bridge deck structure
The invention discloses a steel panel for a bridge and a bridge deck structure, and aims at solving the problems that an existing bridge deck is poor in anti-fatigue performance, a pavement layer is seriously damaged and the like. According to the technical scheme, the steel panel is characterized by comprising a main plate (11) and a first auxiliary plate (12); the first auxiliary plate (12) is perpendicular to the main plate (11), and the first auxiliary plate (12) is formed by bending an edge steel plate of the main plate (11); a plurality of connecting pieces (13) are arranged on the main plate (11), and one end of each connecting piece (13) is connected with the main plate (11); the connecting piece (13) and the first auxiliary plate (12) are located on the surface of the same side of the main plate (11). The steel main plate and the steel top plate are far away from the neutral layer, the inertia moment and the rigidity of the bridge deck structure are greatly improved, the probability of welding fatigue cracking is reduced, and the service life of the bridge deck is prolonged.
本申请公开了一种桥梁用钢面板和桥面结构，现有桥面板抗疲劳性能差、铺装层的病害严重等问题，其技术方案要点为包括主板(11)和第一副板(12)；所述第一副板(12)与主板(11)垂直，第一副板(12)由主板(11)边缘钢板折弯形成；所述主板(11)上具有多个连接件(13)，所述连接件(13)的一端与主板(11)相连；所述连接件(13)与第一副板(12)位于主板(11)的同一侧表面。使得钢制的主板和顶板远离中性层，桥面结构的惯性矩和刚度得到了极大的提高，降低了焊接疲劳开裂的概率，提高了桥面使用寿命。
