Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] Such as Figure 1-6 shown.
[0025] A cable-stayed pedestrian bridge slab is formed by connecting multiple prefabricated segments. The precast segments include end precast segments, standard precast segments, supporting precast segments and spanning precast segments. Wherein, one side of the end prefabricated segment is a straight edge, and the other side is provided with an upper convex edge; one side of the standard prefabricated segment is provided with a lower convex edge, and the other side is provided with an upper convex edge. edge; the two sides of the supporting prefabricated segment are respectively provided with a lower convex edge; the two sides of the bridged prefabricated segment are respectively provided with an upper convex edge; the shape of the upper convex edge and the lower convex edge are the same, Can be spliced smoothl...

The invention relates to a cable-stayed pedestrian bridge board and a construction method. The bridge board is formed by connecting a plurality of prefabricated segments. The prefabricated segments include the end prefabricated segments, the standard prefabricated segments, the supporting prefabricated segments and the bridging prefabricated segments. During construction, the supporting prefabricated segments are installed on a main tower, the standard prefabricated segments are sequentially connected along the two sides of the supporting prefabricated segments, the ends are connected with the end prefabricated segments, and the bridge board is formed. The bridge board is decomposed into the multiple segments, and the segments can be produced inside a factory and conveyed to an installation site. Meanwhile, great convenience is brought to on-site installation construction; on the premise of ensuring the bridge strength and the installation progress, the influence on traffic below the bridge board is effectively avoided, and the high popularization value is achieved.
Description
technical field [0001] The invention relates to a bridge structure and a construction method thereof, in particular to a bridge slab suitable for a cable-stayed pedestrian bridge and a construction method thereof, in particular to a cable-stayed pedestrian bridge slab and a construction method thereof. Background technique [0002] There are various forms of pedestrian bridges in my country, and most of them are steel structures and reinforced concrete simply supported beam bridges. Among them, the cable-stayed bridge is being widely used in urban pedestrian bridges because of its beautiful shape. However, most cable-stayed footbridges are not real "cable-stayed footbridges" at present, but unstressed cable-stayed cables are set above the simply supported girder bridge to form a cable-stayed landscape form. The real cable-stayed bridge is difficult to popularize due to factors such as its large span, the difficulty of prefabricating and transporting the main span bridge sla...
