The lifting rope 6 can pass through the reserved hole 20 and be connected to the finished flue 17 provided below the floor slab 19. Lifting the lifting rope 6 can drive the movement of the finished flue 17 and align the end of the finished flue 17 with the reserved hole 20.

[0033] In this embodiment, the bracket includes a support assembly and a connecting rod 7. The number of support assemblies is multiple and they are connected by the connecting rod 7. The pulley assembly is connected to the connecting rod 7. In this embodiment, the number of support assemblies is two; in other embodiments, the number of support assemblies can also be adjusted according to the usage requirements. The multiple support assemblies are arranged in parallel and connected by the connecting rod 7.

The second support rod 3 is provided with a limit hole, and the limit hole can correspond to any one of the adjustment holes and is fixed by the limit pin 4 to adjust the length of the support assembly. Preferably, both the first support rod 2 and the second support rod 3 are square tubes and the inside of the second support rod 3 is hollow to be sleeved outside the first support rod 2, so as to realize the free stretching of the support assembly to facilitate the adjustment of the length.

[0035] In this embodiment, the connecting rod 7 is movably arranged along the length direction of the support assembly. A plurality of positioning members 5 are arranged at intervals along the length direction of each support assembly. The connecting rod 7 can be connected to any one of the positioning members 5. Preferably, the number of positioning members 5 included in each support assembly is the same and they correspond one by one. The connecting rod 7 can be connected to the corresponding positioning member 5. In this embodiment, the connecting rod 7 can be adjusted along the length direction of the support assembly, and it can also be ensured that the connecting rod 7 is perpendicularly connected to the multiple support assemblies, ensuring the structural stability. Through the connecting rod 7 movably connected to the support assembly, the relative positions of the pulley assembly, the lifting rope 6 and the support assembly can be adjusted, which can ensure that the bracket can be installed in a complex pipeline environment, and it can be ensured that the lifting rope 6 can pass through the reserved hole 20 to lift the finished flue 17, realizing the accurate alignment of the end of the finished flue 17 and the reserved hole 20, saving manpower and ensuring the construction quality at the same time. Preferably, the multiple positioning members 5 are evenly distributed on the corresponding second support rod 3.

[0036] In this embodiment, the connecting rod 7 can be slidably connected to the corresponding support assembly to adjust the interval between adjacent support assemblies, which is more suitable for complex and diverse installation environments. In this embodiment, each positioning member 5 can be prepared as a U-shaped clip. The opening of the U-shaped clip faces the support assembly and the end is connected to the support assembly. Preferably, both ends of the U-shaped clip are respectively connected to the second support rod 3. The U-shaped clip is provided with bolt holes. The connecting rod 7 can be movably inserted into the corresponding positioning member 5 and fixed by screwing a fastening bolt 9 at the bolt hole. The fastening bolt 9 is a butterfly bolt, which is not only convenient for personnel to adjust the tightness, but also convenient for adjusting the fastening bolt 9. After the fastening bolt 9 passes through the bolt hole of the positioning member 5, it can abut against the connecting rod 7. A support rib plate is arranged on the side of each positioning member 5, and the support rib plate is connected to the U-shaped clip and the support assembly.

[0037] In this embodiment, the support assembly can be inclined. Preferably, after being installed, the support assembly can be inclined at 45°. The bracket further includes a fixing assembly. The fixing assembly includes a first clamping member and a second clamping member. The first clamping member is connected to the second clamping member and is arranged at an angle. The support assembly is connected to the first clamping member for fixation. Preferably, the first clamping member and the second clamping member are perpendicularly connected to form a right-angle support plate 13, and the middle part of the outer corner where the first clamping member and the second clamping member are connected is connected to the support assembly. The fixing assembly further includes a backing plate 1, and the backing plate 1 is connected to the end of the support assembly away from the right-angle support plate 13. In this embodiment, the backing plate 1 is connected to the first support rod 2, and the second support rod 3 is connected to the right-angle support plate 13. In this embodiment, the support assembly can be quickly installed through the fixing assembly. In a construction scenario, a finished flue 17 needs to be installed at the corner of the kitchen. Before the finished flue 17 is aligned with the reserved hole 20, the bracket can be installed on the floor of the upper floor at the installation position of the finished flue 17 first. The first support rod 2 abuts against the wall 18 through the backing plate 1. The backing plate 1 can increase the contact area between the support assembly and the wall surface and improve the stability of the bracket after installation; the second support rod 3 abuts against the reserved hole 20 of the floor slab 19 through the right-angle support plate 13. The first clamping member and the second clamping member are connected and form an angle, and the inner corner of the angle fits with the outer corner of the floor slab 19 at the reserved hole 20 for support and fixation. The first clamping member and the second clamping member are arranged at an angle, which can ensure that the support assembly is firmly supported at the reserved hole 20. The installation of this embodiment is simple and fast, and is more suitable for the installation at the corner with limited space. The first clamping member and the second clamping member can be made of double-layer steel plates and welded to each other to form an integral body. Multiple reinforcing rib plates are welded between each double-layer steel plate, so as to increase the structural strength of the support plate and ensure the support effect.
