Description

Technical Field

[0001] This application relates to a fire-resistant detachment device, and more particularly to an air conditioning smoke exhaust system and a fire-resistant detachment device capable of detaching the duct from the sleeve. Background Technology

[0002] Air conditioning smoke exhaust systems use sleeves installed on walls. Both ends of the sleeve are connected to the duct via flanges. Fire dampers can be installed inside the sleeve, which are normally open to allow air circulation between the building's interior and exterior, reducing stuffiness and achieving ventilation. In the event of a fire, the fire dampers can be closed to prevent the fire from spreading and reducing damage, thus preventing the fire from spreading further. Currently, the flanges at both ends of the sleeves are mostly connected to the duct with metal bolts. During a fire, the sleeve and duct remain connected, keeping the air conditioning smoke exhaust system unobstructed. This prevents the duct from being disconnected from the sleeve in time, allowing high temperatures at the fire scene to easily pass through the sleeve and duct, and potentially allowing the fire to spread to other rooms via the air conditioning smoke exhaust system.

Figure 9As shown), the first included angle θ1 is less than 90 degrees, thus achieving a better fastening effect. A second included angle θ2 can be formed between the second end 313 and one side of the middle section 311. This second included angle θ2 is greater than or less than 90 degrees, providing a better fixing effect for the first screw 32. The first screw 32 is screwed onto the second end 313 of the fastener 31. The first end 312 of the fastener 31 is fastened onto one of the first flange 14 and the second flange 21. The first screw 32 is tightened against the other of the first flange 14 and the second flange 21, allowing the duct 2 and the sleeve 1 to be securely connected using these fireproof release devices 3, thus connecting the duct 2 to the sleeve 1.

[0036] In this embodiment, the air conditioning exhaust system further includes multiple second screws 4 and multiple nuts 5. At least one of the second screws 4 and nuts 5 is made of plastic, that is, either one of the second screws 4 or the nuts 5 is made of plastic, or both the second screws 4 and nuts 5 are made of plastic. The second screws 4 and nuts 5 are made of plastic and have a low melting point. The first connecting holes 15 correspond to the second connecting holes 22. The second screws 4 are respectively inserted into the corresponding first connecting holes 15 and second connecting holes 22 and are respectively screwed onto the nuts 5, so that the duct 2 can be connected to the sleeve 1 by screw fastening.

[0037] In this embodiment, a plurality of plastic flange clips 6 may be further provided between the first flange 14 of the sleeve 1 and the second flange 21 of the duct 2. These plastic flange clips 6 are made of plastic and have a low melting point. The cross-section of these plastic flange clips 6 is C-shaped. These plastic flange clips 6 are clamped on the outer edges of the first flange 14 and the second flange 21, so that the duct 2 can be more securely connected to the sleeve 1. Preferably, each of these plastic flange clips 6 has a clamping body 61, one end of which is connected to a lever 62. The clamping body 61 can be clamped on the outer edges of the first flange 14 and the second flange 21. When the plastic flange clip 6 is to be disassembled, it can be levered outward using the lever 62 so that the plastic flange clip 6 can be disengaged from the first flange 14 and the second flange 21. In this embodiment, the melting point of the second screw 4, nut 5 and plastic flange clip 6 can be, for example, between 100 and 300°C.

[0038] Please see Figures 1 to 4 In this application, the sleeve 1 and the duct 2 are connected by a fireproof detachment device 3. When a fire occurs and the fastener 31 or the first screw 32 reaches its melting point, the fastener 31 or the first screw 32 will be damaged, and the duct 2 will be detached from the sleeve 1. This prevents the high temperature at the fire scene from being transmitted through the sleeve 1 and the duct 2, and also prevents the fire from spreading to other rooms through the air conditioning smoke exhaust system.

[0039] Furthermore, the sleeve 1 and the duct 2 of this application can also be connected by the second screw 4, nut 5, and plastic flange clip 6. When a fire occurs and the melting point of the second screw 4, nut 5, and plastic flange clip 6 is reached, the second screw 4, nut 5, and plastic flange clip 6 will be damaged, and the duct 2 will be detached from the sleeve 1. This prevents the high temperature at the fire scene from being transmitted through the sleeve 1 and the duct 2, and also prevents the fire from spreading to other rooms through the air conditioning smoke exhaust system.
