[0042] Reference Figures 3 to 5 As shown, the present invention provides a construction method of a turnover string-type post-casting strip side formwork quick-support and quick-disassembly formwork structure, comprising the following steps:

[0043] S1. A plurality of upper steel bars 5 and a plurality of lower steel bars 6 are arranged in the post-cast zone, and the upper steel bars 5 and the lower steel bars 6 are respectively connected to the two pre-cast structures 4.

[0044] S2. The vertical baffles 1 of the two sets of comb-tooth molds 1 are attached to the side of the first cast structure 4 and are arranged in the gap between two adjacent upper steel bars 5 and the gap between the lower steel bars 6 in the horizontal direction.

[0045] S3. The pressure plate 21 of the support assembly is arranged between the upper steel bars 5 and the lower steel bars 6 and is attached to the side of the plurality of vertical baffles 1 away from the precast structure 4.

[0046] S4. Support the top support member 22 of the support assembly between the two pressing plates 21 so that the pressing plates 21 are pressed against the side of the plurality of vertical baffles 1 away from the precast structure 4.

[0047] S5. Pour the concrete of the post-cast joint.

[0048] S6. Adjust the length of the supporting member 22 so that the supporting member 22 is separated from the pressing plate 21.

[0049] S7, pull the pressing plate 21 out from between the upper steel bars 5 and the lower steel bars 6.

[0050] S8. Hoist the connecting rope 12 of the comb-tooth mold 1 so that the multiple vertical baffles 1 of the comb-tooth mold 1 are pulled out from the post-casting belt.

[0051] In this embodiment, the upper steel bars and the lower steel bars are arranged in the post-cast strip between two adjacent pre-cast structures. The side surfaces of the two pre-cast structures are provided with pressure plates. The two pressure plates are fixed by support assemblies. The arrangement interval of the support assemblies is the same as that of the upper steel bars and the lower steel bars. A plurality of vertical baffles are arranged between adjacent support assemblies and behind the pressure plates. The top of the vertical baffle is a cable tube. A connecting cable is arranged in the cable tube that runs horizontally through the center. The vertical baffles are symmetrically distributed at the concrete interface positions of the post-cast strips on both sides and are arranged perpendicular to the pressure plates.

[0052] The top support member of the support assembly includes a support rod, a base and a base plate. The base plate is attached to one side of the pressure plate. The base is attached to the other side of the pressure plate. The support rod is perpendicular to the vertical baffles set up on both sides. The vertical baffles are detachably connected to the connecting rope and the pressure plate.

[0053] The support rod is a top wire or a screw rod. The vertical baffle is a steel sheet with a cable tube on the top. The pressure plate is a steel sheet. The connecting cable and the vertical baffle are sleeve-connected or clamped.

[0054] When using the revolvable serial-piece post-casting strip side formwork quick-support and quick-disassembly formwork structure of the present invention, firstly, a pressure plate is set on the side surface of the pre-casting structure, and a support assembly is set according to the interval between the original upper steel bars and the lower steel bars, and the pressure plate is fixed. At this time, a certain gap needs to be left between the post-casting strip surface and the pressure plate, and the vertical baffle is inserted into the gap so that the vertical baffle is stuck between the side surface of the pre-casting structure and the pressure plate. At this time, the base of the support assembly is rotated inward so that the base and the base plate are tightly attached, and the vertical baffle and the pressure plate cannot move.

[0055] When it is time to dismantle after use, you only need to rotate the base backwards to remove the pressure plate and vertical baffles, and pull the connecting ropes that string the vertical baffles together to pull out the vertical baffles. In this way, the installation and removal of the support components of the entire post-casting zone area are completed.

[0056] The recyclable string-type post-casting strip side formwork quick-support and quick-disassemble formwork structure of the present invention is completed based on the traditional post-casting strip wooden formwork support. The traditional post-casting strip wooden formwork support requires manual cutting of grooves on the wooden formwork according to the steel bar spacing to embed the steel bars. After the concrete is poured, the formwork is not easy to take out, which wastes a lot of formwork and wood, and cannot be used for a second time.

[0057] The turnaround string-type post-cast strip side formwork quick-support and quick-dismantle formwork structure of the present invention can meet the needs of post-cast strip formwork support of various steel bar spacings through the size and number of vertical baffles, and use the base to timely tighten the comb tooth formwork to ensure stable support of the post-cast strip formwork and beautiful molding quality, thereby greatly improving the support efficiency of the post-cast strip formwork.

[0058] The installation and disassembly of the turnover string-type post-casting strip side formwork quick-support and quick-disassembly formwork structure of the present invention can be adjusted at any time through the base of the supporting component. At the same time, the vertical baffles, connecting ropes and pressure plates are all detachably connected. Compared with the original comb plate structure that uses templates to cut grooves, it is more convenient to disassemble and assemble, and will not waste templates. It can be recycled for many times, thereby improving utilization and reducing costs.

[0059] The revolvable, string-type post-casting strip side formwork quick-support and quick-dismantle formwork structure of the present invention can improve construction efficiency and flexibly allocate to various areas for use according to actual conditions. The revolvable, string-type post-casting strip side formwork quick-support and quick-dismantle formwork structure of the present invention can quickly complete the installation and disassembly of the post-casting strip formwork, and at the same time can produce significant benefits in terms of economic benefits and construction period.

[0060] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
