Description

Technical Field

[0001] This utility model relates to the field of architectural design technology, and in particular to a ventilation duct structure for architectural design. Background Technology

[0002] Ventilation ducts are an indispensable and important component of modern building environment systems. Their main function is to achieve effective air transport, distribution and regulation. They are widely used in various buildings such as residential buildings, office buildings, hospitals, shopping malls and industrial plants. Ventilation ducts not only undertake the task of delivering fresh air into indoor spaces and exhausting polluted air, but also play a key role in fire smoke extraction, humidity regulation and pollutant control. The quality of their performance directly affects the indoor air quality, energy efficiency and health and safety of people in the entire building.

[0003] Traditional ventilation ducts are mostly made of metal materials such as galvanized steel sheets. These materials have advantages such as high strength and easy processing. However, in practical applications, in order to meet building fire protection codes and sound insulation requirements, it is usually necessary to add an additional fireproof insulation layer or sound insulation coating to the outer layer of the duct. Although this structure improves the safety and comfort of the system to a certain extent, it has obvious defects. Due to the combined effects of long-term internal and external vibration, temperature fluctuations, humidity corrosion, and installation stress, the outer functional material is prone to gradual weakening of adhesion, material aging, delamination, and even powdering and falling off. This not only leads to a gradual decline in fire resistance and sound insulation performance, but also poses the risk of debris contaminating the airflow and affecting indoor environmental hygiene. At the same time, the construction process of the outer coating is complex, and the requirements for on-site installation quality and subsequent maintenance are high, making it difficult to guarantee overall reliability and durability. Therefore, the industry urgently needs a new type of ventilation duct structure that can fundamentally overcome the above defects and achieve a unity of function, structure, and durability. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation duct structure for building design, which solves the problem that the outer layer material of traditional ventilation ducts is prone to falling off.

[0005] To achieve the above objectives, this utility model provides a ventilation duct structure for building design, including a duct body, the duct body including a metal panel, a first flange fixedly installed at one end of the duct body, a second flange fixedly installed at the other end of the duct body, a fireproof layer filled inside the metal panel, sound insulation cotton filled inside the metal panel, a metal mesh fixedly installed between the fireproof layer and the sound insulation cotton, several first slots opened on the inner wall of the first flange, and connecting components installed between adjacent duct bodies. The duct body serves as the core ventilation channel, conveying airflow. The metal panel constitutes the main outer shell of the duct, providing structural support and protection. The first flange and the second flange are located at the two ends of the duct to connect adjacent duct sections. The fireproof layer filled inside the duct effectively improves the fire resistance and flame retardant performance of the duct. The tightly filled sound insulation cotton further reduces noise during airflow transmission. The metal mesh placed between the fireproof and sound insulation materials enhances the integrity of the internal materials and the structural stability. The first slots are opened on the inner side of the flange to cooperate with the locking block for quick pre-positioning.

[0006] The connecting assembly includes through holes. Several through holes are provided on the first flange and the second flange. Adjacent pipe bodies are connected by fastening bolts. The through holes are distributed on the flanges to facilitate the passage and fixation of the fastening bolts. The fastening bolts apply a connecting force to ensure a tight connection between the flanges.

[0007] The second flange has a connecting plate fixedly installed at the end away from the main pipe body. A sealing ring is fixedly installed on the outside of the connecting plate. The connecting plate is fixed to the end of the flange to guide and support adjacent pipes. The sealing ring surrounds the outside of the connecting plate to ensure airtightness at the interface and prevent leakage.

[0008] The connecting plate has several second slots on its outer side that correspond to the first slot. A locking block is movably arranged on the outer side of the second slot. The second slot and the first slot are arranged to accommodate the insertion of the locking block. The locking block can be flexibly extended and retracted under the action of a spring to achieve quick engagement and disengagement.

[0009] A limiting plate is fixedly installed at one end of the card block near the second slot. A spring is fixedly installed between the card block and the second slot. The limiting plate is connected to the card block to restrict its movement range and prevent it from coming out. The spring provides continuous elastic force to keep the card block in a stable and locked state.

[0010] The bottom of the main pipe body is movably equipped with a support frame, which is connected to the wall by a suspension wire. The support frame bears the weight of the main pipe body and suspends it in the air. The suspension wire connects the support frame to the building wall to achieve stable suspension installation of the entire pipeline system.

[0011] This ventilation duct structure adopts a modular unit design. During installation, the main body of the duct can be initially fixed by quick docking and snap-fit ​​positioning, which greatly simplifies the traditional multi-step assembly process, significantly improves construction efficiency, and reduces overall working hours and labor costs. The duct integrates multiple layers of functional materials. The metal panel is continuously filled with fireproof layer and sound insulation cotton. The metal mesh in the middle strengthens the integrity and interlayer bonding, realizing the integration of fireproof and sound insulation performance. This enhances the safety and environmental adaptability of the duct during operation. The connection parts are equipped with a quick-locking structure with spring clips and sealing rings to achieve a seal upon connection, effectively preventing air leakage and displacement. The whole system is stably hoisted by support frames and lifting wires, making the system installation more secure, the airtightness better, and the maintenance more convenient.

The metal panel 5 is internally filled with a fireproof layer 6 and sound-insulating cotton 7. A metal mesh 8 is fixedly installed between the fireproof layer 6 and the sound-insulating cotton 7. Several first slots 9 are formed on the inner wall of the first flange 2. Connecting components are installed between adjacent duct bodies 1. The duct body 1 serves as the core channel guiding airflow, and the metal panel 5 constitutes the duct shell, providing basic protection and support. Flange 2 and the second flange 3 are used for pipe end connection, respectively. Fireproof layer 6 is filled inside to achieve flame retardancy and fire protection. Sound insulation cotton 7 further absorbs airflow noise and improves the acoustic environment. Metal mesh 8 enhances the integrity of internal materials and structural stability. The first slot 9 is used for positioning function in the snap-fit ​​connection. The construction personnel first install and fix the pipe body 1 through the lifting wire 16 and the support frame 15, and then connect the adjacent pipe bodies 1 through the connecting components. That is, the connecting plate 10 of the first group of pipes is inserted into the first flange 2 of the second group of pipes. Under the action of spring 14, the locking block 12 is locked into the first slot 9 to achieve initial limiting and prevent installation deviation.

[0021] The connecting assembly includes through holes 4. Several through holes 4 are provided on the first flange 2 and the second flange 3. Adjacent pipe bodies 1 are connected by fastening bolts. A connecting plate 10 is fixedly provided at the end of the second flange 3 away from the pipe body 1. A sealing ring 17 is fixedly provided on the outside of the connecting plate 10. The connecting assembly includes through holes 4 and other structures to provide channels for connecting multiple pipes. The through holes 4 allow fastening bolts to pass through and be tightened. The connecting plate 10 is provided at the end of the second flange 3 to guide the docking operation. The sealing ring 17 ensures that the connection interface is airtight and prevents leakage.

[0022] The outer side of the connecting plate 10 has several second slots 11 corresponding to the first slot 9. A locking block 12 is movably arranged on the outer side of the second slot 11. A limit plate 13 is fixedly arranged at one end of the locking block 12 near the second slot 11. A spring 14 is fixedly arranged between the locking block 12 and the second slot 11. A support frame 15 is movably arranged at the bottom of the pipe body 1. The support frame 15 is connected to the wall through a hanging wire 16. The second slot 11 and the first slot 9 together realize the limiting function of the locking block 12. The locking block 12 can quickly engage and release under the action of the spring 14. The limit plate 13 controls the movement range of the locking block 12 to prevent it from falling off. The spring 14 provides continuous elastic restoring force for the locking block 12. The support frame 15 bears the overall weight of the pipe and distributes the load. The hanging wire 16 connects the support frame 15 to the top of the building to achieve suspended installation.

[0023] Working principle: The construction personnel first install and fix the main body of the pipe 1 using the lifting wire 16 and the support frame 15. Then, the adjacent main bodies of the pipe 1 are connected by the connecting components. That is, the connecting plate 10 of the first set of pipes is inserted into the first flange 2 of the second set of pipes. Under the action of the spring 14, the locking block 12 is locked into the first groove 9 to achieve initial positioning and prevent installation deviation. Then, the fastening bolts are passed through the through holes 4 on the first flange 2 and the second flange 3 to complete the fastening connection. The main body of the pipe 1 is equipped with a metal panel 5, which is filled with a fireproof layer 6 and sound insulation cotton 7. A metal mesh 8 is set between the two to enhance the overall structure and functionality. All components are modularly assembled and connected, which is easier to construct and maintain than the traditional method of covering with a fireproof layer.
