Description

Technical Field

[0001] This utility model relates to the field of duct riser support technology, and in particular to a common plate flange duct riser fixing support. Background Technology

[0002] Common plate flange ducts, also known as flangeless ducts, have advantages such as saving materials, reducing project investment, and low air leakage, and are widely used in factory ventilation systems and electromechanical projects.

[0003] In existing technologies, duct risers are mainly fixed by fixing duct riser brackets at the wall ring beam. However, due to the fixed structure of the duct riser brackets and the limitations imposed by the position of the wall ring beam and the installation location, the installation location of the duct riser brackets is sometimes difficult to meet construction requirements. This results in the duct riser's fixing strength sometimes failing to meet design requirements, making on-site installation inconvenient. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a common plate flange duct riser fixing bracket, which can more flexibly fix the duct riser and facilitate on-site installation and construction.

[0005] This utility model is achieved using the following technical solution: a common plate flange duct riser fixing bracket, comprising a main support structure, a screw rod, a Z-shaped adapter, and a duct riser. The main support structure is fixed to the inner side of the wall. Nuts are installed on both sides of the connection between the end of the screw rod and the Z-shaped adapter and the main support structure via threaded engagement. A duct flange is provided at the end of the duct riser. One end of the Z-shaped adapter is connected to the main support structure via the screw rod, and the other end of the Z-shaped adapter is connected to the duct flange via bolts.

[0006] Furthermore, the main support structure includes a horizontal support rod, a rod seat, an expansion bolt, a connecting rod, and an L-shaped connecting plate. The bottom end of the horizontal support rod is fixed to the rod seat by bolts and nuts. The expansion bolt is fixed to the inner side of the wall. The rod seat is fixed to the outer end of the expansion bolt by nuts. A connecting rod is provided between the two horizontal support rods. The connecting rod is connected and fixed to the horizontal support rod by an L-shaped connecting plate.

[0007] Furthermore, a cap is provided at the top of the horizontal support rod.

[0008] Furthermore, the horizontal support rod is provided with a row of support rod through holes at equal intervals in both the vertical and horizontal directions.

[0009] Furthermore, the connecting rod is provided with a row of support rod through holes at equal intervals in both the vertical and horizontal directions.

[0010] Compared to existing technologies, the advantages of this utility model are as follows: The common plate flange duct riser fixing bracket of this utility model can be used to connect and fix the duct riser via a threaded rod and a Z-shaped adapter, achieving more flexible fixing of the duct riser while ensuring its fixing strength. Simultaneously, the vertical distance between the Z-shaped adapter and the main support structure can be adjusted using the threaded rod, facilitating on-site construction by adjusting the position of the crossbeam below the main support structure after fixing its position.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0015] The purpose of this utility model is to address the shortcomings of existing technologies by providing a common plate flange duct riser fixing bracket.

[0016] Example 1

[0017] This embodiment provides a common plate flange duct riser fixing bracket, referring to... Figures 1-2As shown, the structure includes a main support structure, a lead screw 8, a Z-shaped adapter 12, and a duct riser 20. The main support structure is fixed to the inside of the wall 4. Nuts are installed on both sides of the connection between the end of the lead screw 8 and the Z-shaped adapter 12 and the main support structure via threaded engagement. A duct flange 9 is provided at the end of the duct riser 20. One end of the Z-shaped adapter 12 is connected to the main support structure via the lead screw 8, and the other end of the Z-shaped adapter 12 is connected to the duct flange 9 via bolts. The main support structure can be fixed at the wall ring beam. The duct riser 20 can be pulled and fixed by extending the lead screw 8 and the Z-shaped adapter 12. This solves the problem of limited fixing positions and quantities of the main support structure in the prior art, and achieves more flexible fixing of the main support structure while ensuring the fixing strength of the duct riser 20.

[0018] Specifically, refer to Figures 1-2 As shown, the main support structure in this embodiment includes a horizontal support rod 1, a rod seat 2, expansion bolts 3, connecting rods 5, and an L-shaped connecting plate 6. The bottom end of the horizontal support rod 1 is fixed to the rod seat 2 by bolts and nuts, and the top end of the horizontal support rod 1 is provided with a rod cap 7 to protect the outer end of the horizontal support rod 1. The expansion bolts 3 are fixed to the inner side of the wall 4, and the rod seat 2 is fixed to the outer end of the expansion bolts 3 by nuts. Multiple horizontal support rods 1 are fixed to the inner wall of the factory building in a vertical direction at intervals. There are two horizontal support rods 1 at each location, and the two horizontal support rods 1 are kept horizontal. A connecting rod 5 is provided between the two horizontal support rods 1, and the connecting rod 5 is connected and fixed to the horizontal support rod 1 by the L-shaped connecting plate 6. The horizontal support rods 1 and the connecting rods 5 are provided with a row of support rod through holes at equal intervals in the vertical and horizontal directions to facilitate their connection with the L-shaped connecting plate 6, the threaded rod 8, and the air duct riser 20, as well as their position adjustment.

[0019] This utility model discloses a common plate flange duct riser fixing bracket. Expansion bolts 3 are fixed to the inner side of the ring beam on the wall 4. The rod seat 2 is connected and fixed to the outer end of the expansion bolts 3, allowing multiple horizontal support rods 1 to be sequentially and spaced apart on the inner wall of the factory in the vertical direction. Each location has two horizontal support rods 1, which remain horizontal. The duct riser 20 can be directly fixed using the main bracket structure. Alternatively, the main bracket structure can be fixed at the ring beam on the wall, and the duct riser 20 can be pulled and fixed by extending it through the threaded rod 8 and Z-shaped adapter 12. This solves the problem of limited fixing positions and numbers of the main bracket structure in existing technologies, allowing for more flexible fixing of the duct riser 20 while ensuring its fixing strength. Simultaneously, the vertical distance between the Z-shaped adapter 12 and the main bracket structure can be adjusted using the threaded rod 8, facilitating on-site construction by adjusting the position of the crossbeam below the main bracket structure after fixing its position.

[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
