Description

Technical Field

[0001] This utility model belongs to the field of duct construction technology, and in particular relates to a structure for a horizontal duct passing through a fire wall expansion joint. Background Technology

[0002] Ductwork construction is a crucial step in the construction of building ventilation and air conditioning systems, encompassing a series of tasks including duct fabrication, transportation, installation, and commissioning. First, materials are selected and ductwork is fabricated according to design requirements to ensure accurate dimensions and quality standards. During transportation, protective measures are taken to prevent deformation and damage. During installation, the ductwork is laid out reasonably and firmly fixed to ensure tight connections.

[0003] In building ventilation systems, when horizontal ducts pass through fire wall expansion joints, the expansion joints expand and contract due to building settlement, thermal expansion and contraction, etc. The ducts are easily squeezed and twisted at the expansion joints, leading to duct damage, loosening of connections, and air leakage, which affects the ventilation effect. Therefore, it is necessary to provide a structure for horizontal ducts passing through fire wall expansion joints. Support components are used to provide stable support for the ventilation ducts, which enhances the stability of duct installation. At the same time, the flexible compensation pipe and connecting plate work together to effectively compensate for the impact of changes in the wall expansion joints on the ducts, ensuring that the ducts remain connected and stable when the wall expands and contracts, thus improving the reliability of the ventilation system.

[0014] In the following description, embodiments of the horizontal duct penetration fire wall expansion joint structure of the present invention will be described with reference to the accompanying drawings.

[0015] Figure 1-4This invention illustrates a horizontal ductwork structure penetrating a fire wall expansion joint according to an embodiment of the present invention. The structure includes an embedded pipe sleeve 1 pre-embedded at the wall expansion joint. A central duct 2 is housed within the inner cavity of the embedded pipe sleeve 1. The inner cavity of the embedded pipe sleeve 1 is filled with a foam filling layer 8, which is in close contact with the surface of the central duct 2. Connecting ventilation pipes 3 are provided on both sides of the central duct 2. A flexible compensation pipe 4 is provided between the central duct 2 and the connecting ventilation pipes 3. Connecting plates 5 are fixedly connected to both sides of the flexible compensation pipe 4. The connecting plates 5 are fixedly connected to the central duct 2 and the connecting ventilation pipes 3 by screws. The surface of the connecting ventilation pipes 3 is provided with… Support assembly 6 includes grooved plates 61 located at the top and bottom of the connecting ventilation duct 3. Suspension screw rods 62 are threaded through the front and rear sides between the two grooved plates 61. The top of the centrally located ventilation duct 2 is fixed to the wall. Two fastening nuts 63 are threaded onto the surface of the suspension screw rods 62. Diagonal bracing plates 64 are provided on the front and rear sides of the top of the connecting ventilation duct 3. Rotary seats 65 are rotatably connected to the top and bottom of the diagonal bracing plates 64. The upper rotating seat 65 is fixed to the wall by expansion bolts, and the lower rotating seat 65 is fixed to the grooved plate 61 by bolts. The diagonal bracing plates 64 and the rotating seats 64... The use of seat 65 provides diagonal bracing and reinforcement to the channel plate 61, thereby reinforcing the connecting ventilation duct 3 and improving its stability after installation. The two fastening caps 63 are tightly fitted to the inner walls of the two channel plates 61 on opposite sides. Guide components 7 are provided on both the front and rear sides of the flexible compensation pipe 4. The guide components 7 include T-shaped supports 71 fixedly connected to the front and rear sides of the connecting ventilation duct 3. A guide rod 72 is welded to the side of the T-shaped support 71 closest to the central air duct 2. T-shaped supports 73 are welded to both ends of the front and rear sides of the central air duct 2. The guide rod 72 slides... The guide rod 72 is connected to the inner cavity of the T-shaped support 73. Two adjusting nuts 74 are threaded to the end of the guide rod 72 away from the T-shaped support 71. There is a reserved position between the adjusting nuts 74 and the T-shaped support 73. Through the setting of the guide assembly 7, the T-shaped support 71, the guide rod 72 and the T-shaped support 73 work together to limit and guide the connection between the central air duct 2 and the connecting ventilation duct 3, thereby improving the connection stability between the central air duct 2 and the connecting ventilation duct 3. At the same time, the setting of the adjusting nuts 74 provides space for the sliding of the guide rod 72, so as to adapt to the changes of the wall expansion joint.

[0016] Working principle: When using this utility model, the user inserts the central air duct 2 into the inner cavity of the pre-embedded pipe sleeve 1, then fills the space between the pre-embedded pipe sleeve 1 and the central air duct 2 with a foam filling layer 8 to fix the central air duct 2. Next, the lifting screw rod 62 is fixed in the designated position. Then, the channel plate 61 is fitted onto the surface of the lifting screw rod 62, and the connecting ventilation pipe 3 is installed between the two channel plates 61. The fastening cap 63 is tightened, causing the fastening cap 63 to compress the connecting ventilation pipe 3, thereby fixing the connecting ventilation pipe 3 in place. Then... The flexible compensation pipe 4 is moved between the central air duct 2 and the connecting ventilation duct 3. A sealing ring is placed on the side of the connecting plate 5 away from the flexible compensation pipe 4. The connecting plate 5 is fixedly connected to the central air duct 2 and the connecting ventilation duct 3 with screws, so that the central air duct 2, the connecting ventilation duct 3 and the flexible compensation pipe 4 remain in a connected state. During use, when the wall expansion joint changes, the flexible compensation pipe 4 extends or compresses itself according to the position change of the central air duct 2 and the connecting ventilation duct 3, thereby ensuring the stability of the connection between the central air duct 2 and the connecting ventilation duct 3.

[0017] In summary: This horizontal ductwork structure passing through the fire wall expansion joint, through the setting of support component 6, supports and fixes the connecting ventilation duct 3. Then, through the cooperation of flexible compensation pipe 4 and connecting plate 5, the central duct 2 and the connecting ventilation duct 3 are compensated and connected. Finally, with the cooperation of guide component 7, the connection stability between the central duct 2 and the connecting ventilation duct 3 is ensured, thus achieving the purpose of stable and reliable installation and easy adaptation to changes in the wall.
