Description

Technical Field

[0001] The present application relates to the technical field of air duct equipment, and in particular to an air duct support structure. Background Art

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air conditioning engineering for industrial and civil buildings. They are a kind of municipal infrastructure to allow air circulation and reduce the concentration of harmful gases. Earthquake-resistant brackets are used to reinforce the mechanical and electrical engineering facilities such as water supply and drainage, fire protection, heating, air ducts, air conditioning, gas, heat, electricity, and communications of buildings. When an earthquake occurs, earthquake-resistant brackets can reduce earthquake damage, reduce and prevent the occurrence of secondary disasters as much as possible, thereby reducing casualties and property losses.

[0003] Most of the existing air duct brackets are fixed and installed by bolts. After vibration, the air duct may be torn or leak at the flange connection due to its rigid connection. The air duct needs to be replaced or repaired, which affects its normal use after the earthquake. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides an air duct support structure.

[0005] The present application provides a duct support structure that adopts the following technical solution:

[0006] A duct support structure, comprising a main pole, a first support pole and a second support pole vertically fixed on a roof, wherein one end of the first support pole and the second support pole are connected to the roof, and the other end is fixed on the main pole, and the projections of the first support pole and the second support pole on the roof are vertical;

[0007] The main rod is provided with a bellows, and flanges are provided at both ends of the bellows.

[0008] A further technical solution is that a hook is provided on the main rod, a ring is provided on the corrugated tube, and the ring is provided on the hook.

[0009] A further technical solution is that a screw rod is arranged on the main rod, a lifting lug with a lifting hole is arranged on the side of the corrugated tube, and the screw rod passes through the lifting lug and is fixed by a nut.

[0010] This application has the following beneficial technical effects:

[0011] By arranging a bellows on the main rod, the air duct can be connected through the flanges at both ends of the bellows. When shaking occurs, the bellows can bend and deform to offset the axial or radial pressure of the air duct, thereby reducing the phenomenon of air duct damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0016] The present application embodiment discloses a duct support structure. Figure 1~Figure 2 A duct support structure includes a main pole 1, a first support pole 11 and a second support pole 12 vertically fixed on a roof, one end of the first support pole 11 and the second support pole 12 are connected to the roof, and the other end is fixed on the main pole 1, and the projection of the first support pole 11 and the second support pole 12 on the roof is vertical.

[0017] The first support rod 11 and the second support rod 12 are used to support the main rod 1, so as to improve the connection strength between the main rod 1 and the roof, and prevent the main rod 1 from tilting and falling off due to shaking of the air duct caused by an earthquake.

[0018] The main rod 1 is provided with a bellows 2 , and flanges 21 are provided at both ends of the bellows 2 .

[0019] Reference Figure 1 In one embodiment, a hook 31 is provided on the main rod 1 , a ring 32 is provided on the corrugated tube 2 , and the ring 32 is provided on the hook 31 .

[0020] There are four hanging rings 32 and they are connected to the four corners of the bellows 2 through steel wires 33. The bellows 2 is hung on the hook 31 and connected to the air duct through the flange 21. When shaking occurs, the air duct is connected to the bellows 2, and the steel wires 33 can provide a slight shaking margin to reduce the radial force of the air duct. If the shaking amplitude is large, the bellows 2 can be bent and deformed to offset the axial force of the air duct, thereby reducing the phenomenon of air duct damage.

[0021] Reference Figure 2 In another embodiment, a screw rod 41 is provided on the main rod 1 , and a lifting ear 42 with a lifting hole is provided on the side of the corrugated tube 2 . The screw rod 41 passes through the lifting ear 42 and is fixed by a nut 43 .

[0022] The screw rods 41 are fixedly arranged on both sides of the bellows 2. When shaking occurs, the bellows 2 can be prevented from moving toward the two sides. The air duct can reduce the damage rate of the air duct only by the deformation of the air duct, thereby improving the stability of the air duct fixation.

[0023] It should be noted that in the present utility model, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
