Embodiment 1

[0027] Such as figure 1 As shown, the present invention is a horizontal assembly system for the prefabricated bridge pier formwork of the prefabricated bridge. 2 (such as figure 1 shown), the assembling trolley 2 moves back and forth on the guide rail 1 by the moving pulley 9 arranged at the bottom, (as Figure 2-3 As shown) the assembled trolley 2 includes a mobile support 4, a lifting adjustment system 5 and a bridge formwork support frame 6, and the bridge formwork support frame 6 is movably arranged on the mobile support 4 to adjust the lift through the lift adjustment system 5. The guide rail 1 is a double guide rail structure. The mobile support 4 includes a supporting frame 8 formed by four supporting legs 7, and the four supporting legs 7 are welded and fixed by reinforcing beams. The four supporting legs 7 can be made of square tube steel, and the lower ends of the supporting legs 7 are provided with movable The pulley 9 and the upper end of the support leg 7 are p...

Embodiment 2

[0034] Such as Figure 1-5 As shown, the present invention is a horizontal assembly system for prefabricated bridge pier templates of prefabricated bridges. On the basis of Embodiment 1, there are two sets of scissor telescopic frames 16 . Pass through, two sets of scissors telescopic frame 16 lower end four joints,; Share a silk sleeve 17 in pairs, thereby control two sets of scissors telescopic frames 16 expansion and contraction by an adjustment lifting screw rod 15. Realizing the lifting support by two sets of scissor telescopic frames 16 can improve the lifting stability of the assembled trolley 2 and also provide bearing capacity.

Abstract

The invention discloses a horizontal splicing system used for assembly type bridge prefabricated pier formworks. The horizontal splicing system comprises guide rails and splicing trolleys. The guide rails are horizontally arranged and provided with the multiple splicing trolleys used for bearing the bridge formworks. Each splicing trolley comprises a mobile support, a lifting adjustment system and a bridge formwork bracket, wherein the bridge formwork bracket is movably arranged on the mobile support, and rising and falling of the bridge formwork bracket are adjusted through the lifting adjustment system. According to the horizontal splicing system used for the assembly type bridge prefabricated pier formworks, the lifting splicing trolleys bearing the bridge formworks are arranged on the horizontal rails, and the heights of the bridge formworks on the trolleys can be adjusted through the lifting splicing trolleys so that the butt joint fit degree of all bridge formwork connectors can be effectively improved, the splicing trolleys can move on the guide rails front and back, front-back butt joint between the bridge formworks is facilitated, and working intensity of constructors is effectively relieved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a horizontal assembling system for prefabricated bridge pier templates of fabricated bridges. Background technique [0002] Large-scale bridge steel tower sections generally require pre-assembly, and physical pre-assembly is divided into vertical pre-assembly and horizontal pre-assembly: for shorter tower sections, vertical pre-assembly is generally used at home and abroad; for longer lengths For large ones, due to the limitations of lifting equipment and factory building height, only horizontal pre-assembly is used. When using horizontal pre-assembly, the most difficult problem to solve is: the metal contact rate must meet the higher standard requirements; the self-weight of the tower section cannot affect the column alignment. Among them, how to ensure the metal contact ratio requirements between tower sections is the difficulty and key point of horizontal pre-assembly. Co...
