Steel truss girder bridge floor and steel truss girder bridge
The embodiment of the invention provides a steel truss girder bridge floor and a steel truss girder bridge, the bridge floor comprises a main truss, a bridge deck slab and a cross beam, the bridge deck slab is connected with a lower chord member of the main truss, the top surface of the bridge deck slab is not higher than the top surface of the lower chord member of the main truss, and the middle part of the bridge deck slab is sunken downwards to form a passage surface; a plurality of cross beams which are arranged in parallel are arranged on the bottom surface of the bridge deck slab, the length direction of the cross beams is perpendicular to the length direction of the bridge deck slab, the cross beams are connected with main truss lower chord members, and the bottom surfaces of the cross beams are not lower than the bottom surfaces of the main truss lower chord members. On the premise of not changing the size of the main truss rod piece of the steel truss girder bridge, the bridge building height of the steel truss girder bridge is effectively reduced by changing the shape of the bridge deck and then changing the height of the cross beam, the bridge building height is controlled to be below the building height limit value, and the bridge safety is guaranteed.
本申请实施例提供了一种钢桁梁桥面及钢桁梁桥，所述桥面包括主桁、桥面板和横梁，所述桥面板与主桁下弦杆件连接，且所述桥面板顶面不高于所述主桁下弦杆件的顶面，所述桥面板中部向下凹陷形成通行面，所述桥面板的底面设置有多个平行排列的横梁，且所述横梁的长度方向垂直于所述桥面板的长度方向，所述横梁与主桁下弦杆件连接，且所述横梁底面不低于所述主桁下弦杆件的底面。本申请在不改变钢桁梁桥主桁杆件尺寸的前提下，通过采用改变桥面板板面形状，进而改变横梁高度变化的方式，有效减小钢桁梁桥桥梁建筑高度，将桥梁建筑高度控制在建筑高度限值之下，保证桥梁安全。
