Problems solved by technology
[0003] The construction of cast-in-place beams is the key line of the construction process, and the construction period is tight. If the first method above is used to remove the brackets, it will affect the straight-line construction period by 1-2 days, so it is not applicable
The cast-in-place beam construction area is located in the shoal area, where ships such as floating cranes cannot enter, and the hoisting clearance is small. It is necessary to remove the bottom construction platform before the mobile formwork is in place, so the above-mentioned methods 2 and 3 are not applicable

Embodiment Construction
[0043] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0044] see Figure 1-14 As shown, a downward mobile formwork supporting bracket spanning transfer construction method, the transfer construction method requires the use of transfer construction equipment, and four sets of bracket piers are arranged below the transfer construction equipment, which are respectively the bracket piers to be removed. Pile A, pouring beam section pier pile one B, pouring beam section pier pile two C and bracket pier pile D to be installed; the construction method specifically includes the followi...

The invention discloses a construction method for straddling transfer of downward mobile formwork supporting brackets. The construction method specifically includes the following steps: Step 1: The walking motor arranged on the reverse trolley works to drive the travel wheels to rotate, and the reverse trolley moves to the leading At the front end of the beam, the front reversing device is installed on the bottom of the reversing trolley through four sets of suspenders, and then the reversing trolley moves back to the front end of the main beam, and the L-shaped beam is fixed and installed through the struts; the construction method of the present invention does not occupy the linear construction period, which can effectively shorten the unit The construction period of the cast-in-place box girder with holes; this method uses the gantry crane and the reversing trolley on the top of the leading beam of the mobile formwork to carry out the straddling removal of the support bracket, which is not restricted by the terrain, can effectively improve the utilization rate of equipment, and reduce labor idleness.
Description
technical field [0001] The invention relates to the technical field of leap-type disassembly and assembly of large components, in particular to a leap-type transfer construction method of a downward mobile formwork support bracket. Background technique [0002] The mobile formwork construction method is widely used in in-situ construction of simply supported beams, continuous beams and other bridge types due to its short construction period and good integrity of beam segments. However, due to the huge size of the components and the limitations of the construction site and construction equipment, the disassembly and assembly of the support brackets of the downward mobile formwork is still a difficult problem in this construction method. At present, the downward mobile formwork at home and abroad mainly adopts the following three methods to support the bracket: 1. After the prestressed tendons of the cast-in-place beam are stretched, the mobile formwork is hung on the cast-in-...
