Construction method for installing bridge deck prefabricated slabs through cable crane
The invention discloses a construction method for mounting bridge floor prefabricated slabs by using a cable crane, which comprises the following steps of: erecting and mounting bridge arch rings and steel beams by using a cable hoisting method, and circularly and symmetrically mounting the bridge floor prefabricated slabs from two banks to a midspan by using the cable hoisting method; before the bridge floor prefabricated slab is installed, the shear nails are not welded to the positions, corresponding to the shear nail grooves of the bridge floor prefabricated slab, of the steel beams. The transverse steel bars between every two adjacent bridge deck prefabricated slabs are arranged in a staggered mode, and the longitudinal steel bars between every two adjacent bridge deck prefabricated slabs are arranged in a staggered mode. The installation process of the bridge floor prefabricated slab comprises the following steps that the bridge floor prefabricated slab is moved to the position below the cable sling to be hoisted; the suspension bridge surface prefabricated slab is hoisted by the cable; installing rubber cushion blocks between the bridge deck prefabricated slabs and the steel beams; the splicing steel bars are manually assisted to be pulled and moved; mounting a bridge floor prefabricated slab in place; shear nails in the shear nail grooves are welded; bridge deck prefabricated slabs are circularly and symmetrically installed from the two banks to the midspan; and shrinkage-compensating concrete pouring is carried out on bridge deck prefabricated slab wet joints and in shear nail grooves.
本发明公开了一种利用缆索吊安装桥面预制板的施工方法，采用缆索吊装法架设安装桥梁拱圈及钢梁，并采用缆索吊装法从两岸到跨中循环对称安装桥面预制板；在安装桥面预制板前，钢梁上对应桥面预制板的剪力钉槽的位置未焊接剪力钉；相邻两个桥面预制板之间的横向钢筋交错设置，相邻两个桥面预制板之间的纵向钢筋交错设置；桥面预制板的安装过程如下：将桥面预制板移到缆索吊具下待吊；缆索吊起吊桥面预制板；安装桥面预制板与钢梁间的橡胶垫块；人工辅助扳移接茬钢筋；桥面预制板安装到位；焊接剪力钉槽内剪力钉；循环对称从两岸向跨中安装桥面预制板；进行桥面预制板湿接缝及剪力钉槽内补偿收缩混凝土浇筑。
