Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] combine Figure 1 to Figure 5 , a steel-concrete composite bridge with cantilever construction, including several bridge segments 1, the bridge segment 1 includes an outer formwork 2 and concrete 3, the outer formwork 2 is a steel formwork, composed of a top form, a side form and a bottom form, the side formwork The mold is composed of two groove-shaped steel plates, the bottom mold is composed of one steel plate, and the top mold is composed of two L-shaped steel plates. One end of the shaped steel plate is respectively fixed on the top two wings of the side form by bolts 5, extending outwards, and the other end is directed upwards. A plurality of rivets 4 are evenly arranged on the inner wall of the side formwork of the outer formwork 2 and the tops of the top formwork and the bottom formwork. The two adjacent outer formworks are connected and fixe...

The invention discloses a cantilever construction steel-concrete combined bridge and a construction method thereof. The cantilever construction steel-concrete combined bridge comprises a plurality of bridge segments. Each bridge segment comprises an outer formwork and concrete, wherein the outer formwork is composed of a top mold, a side mold and a bottom mold, the bottom mold is fixed to the bottom of the side mold through a bolt, the top mold is fixed to the top of the side mold through a bolt and extends outwards, and the concrete is poured into the top mold and an inner cavity composed of the side mold and the bottom mold. Every two adjacent outer formworks are fixedly connected through bolts. According to the cantilever construction steel-concrete combined bridge and the construction method, construction is easy and convenient, the problem that the bridge segments are not matched during butt joint is solved, and the stress performance of the bridge is improved.
Description
technical field [0001] The invention belongs to the field of civil engineering bridges, and in particular relates to a cantilever construction steel-concrete composite bridge and a construction method thereof. Background technique [0002] Modern cantilever construction is mainly hanging basket construction. The hanging basket is a load-bearing frame that can slide or roll along the top of the beam. It is anchored and suspended on the constructed beam section. The formwork can be moved forward on the hanging basket, and the next beam section Reinforcement installation, grouting and other operations. After completing a stage of circulation, the hanging basket can be moved forward and fixed for the next stage of hanging irrigation, and so on until the cantilever irrigation is completed. However, after the concrete strength of each bridge segment meets the predetermined requirements, the external formwork needs to be removed, which requires a lot of manpower and material resou...
