[0046] As shown in Figure 1 The embodiment of the application provides a floor lowering formwork support structure, which comprises a main floor 1, a hanger 2 and a lowering formwork 3. The main floor 1 is formed with a lowering area 6, and a pre-embedded part 4 is arranged on the main floor 1. The hanger 2 is at least partially located below the lowering area 6, and the hanger 2 is connected to the pre-embedded part 4 on the main floor 1. The lowering formwork 3 is mounted on the hanger 2, and the lowering formwork 3 encloses the lowering area 6.

[0047] In the floor lowering formwork support structure provided by the embodiment of the application, the hanger 2 is connected to the main floor 1 by means of the pre-embedded part 4 in the main floor 1, and the lowering formwork 3 is mounted on the hanger 2 to form an integrated formwork with the hanger 2. The arrangement of the pre-embedded part 4 and the hanger 2 enables the lowering formwork 3 to be in a stable state, so that the lowering formwork does not need to be supported by a scaffold when being built. The support structure of the application can improve the construction speed, reduce the required materials and labor, and the hoisted formwork has good integrity, and the problem of setting up and dismantling the scaffold is avoided, thereby not affecting the construction of other processes on the lower floor.

[0048] In some possible embodiments, the lowering formwork 3 comprises a bottom formwork 31 and a side formwork 32 located on the side of the bottom formwork 31. The bottom formwork 31 is located at the bottom of the lowering area 6, and the bottom formwork 31 encloses to form a bottom pouring area 51. The side formwork 32 is located on the side of the lowering area 6, and the side formwork 32 and the main floor 1 form a side pouring area 52, and the side pouring area 52 is communicated with the bottom pouring area 51. The hanger 2 is connected to and supports the bottom formwork 31 and the side formwork 32 respectively.

[0049] The bottom formwork can abut against the main floor 1 directly or indirectly to form a bottom pouring area 51, and the side formwork 32 has a gap between the edge of the main floor 1 on the side of the lowered floor area to form a side pouring area 52. The side pouring area 52 is in communication with the bottom pouring area 51 to form a cavity with a generally "U" shaped cross section, and the two cavities can be poured simultaneously to simplify the construction process. During pouring, the filler closes the lowered floor area 6 formed in the main floor 1 and reaches a predetermined thickness to form a lowered floor structure.

[0050] Further, the supporting structure further includes a support structure 7 supported on the edge of the lowered floor area 6. The support structure 7 can be supported on one side of the main floor 1 below and slightly extended into the lowered floor area 6 on the other side. The bottom formwork can abut against the support structure 7 to avoid the formation of a gap between the side pouring area 52 and the bottom pouring area 51 to cause slurry leakage. The support structure 7 can support the cantilever end on one side of the lowered floor area 6 of the main floor 1 to ensure the stability of the main floor 1 structure, and the support structure 7 extends to one side of the side formwork 32 to prevent slurry from leaking out of the gap between the bottom formwork 31 and the main floor 1 during pouring.

[0051] In some possible embodiments, the hanger 2 includes a top fixing assembly 21 and a bottom fixing assembly 22. The top fixing assembly 21 and the bottom fixing assembly 22 are arranged on opposite sides of the floor along the thickness direction. At least one of the top fixing assembly 21 and the bottom fixing assembly 22 is connected to the embedded part 4, and the top fixing assembly 21 and the bottom fixing assembly 22 are connected. The bottom formwork 31 is connected to the bottom fixing assembly 22, and the side formwork 32 is connected to the top fixing assembly 21. The embodiments of the present application arrange the top fixing assembly 21 and the bottom fixing assembly 22 on opposite sides of the floor along the thickness direction, which facilitates the installation of the side formwork 32 and the bottom formwork 31 respectively, ensures that the side formwork 32 and the bottom formwork 31 have corresponding installation supports, and ensures the stability of the side formwork 32 and the bottom formwork 31 after installation.

Each steel bar can be arranged in one-to-one correspondence with the first screw. The top fixing assembly 21 needs to pass through the formwork and can therefore be selected as a first screw, which is mainly used to connect and fix the side formwork 32 and ensure that the formwork remains stable during pouring of concrete. It should be noted that the connection structure of the screw and the formwork is a conventional solution in the art, and those skilled in the art know that the first screw can adjust the position of the formwork by means of a knob to achieve fine adjustment. The bottom fixing assembly 22 does not need to pass through the formwork and is mainly used to support the bottom formwork 31, and therefore a steel bar is selected. In the construction process, although the steel bar and the screw are both commonly used materials in the construction industry, they have many differences in function, shape and purpose, and correct use and compliance with the requirements of the steel bar and the screw can effectively ensure the strength, stability and reliability of the building.

The second screw rod and the first screw rod and the second screw rod and the steel bar can be full-welded connection.

[0058] In some possible embodiments, the connecting assembly 23 is located between the embedded part 4 and the side formwork 32, and the connecting assembly 23 penetrates the bottom pouring area 51 and the side pouring area 52. The second screw rod penetrates the bottom pouring area 51 and the side pouring area 52, and after pouring is completed, the second screw rod is left in the floor, and in addition to the function of connecting the top fixing assembly 21 and the bottom fixing assembly 22, each second screw rod of the connecting assembly 23 also has the function of reinforcing the concrete structure, improving the load-bearing capacity and stability of the structure. The second screw rod is embedded in the concrete, which enhances the bending strength and tensile strength of the concrete, prevents structural cracks and deformation.
