[0027] For example, in the implementation process, an I-beam refers to a beam with an H-shaped cross section. The upper flange is called an upper flange, the lower flange is called a lower flange, and the plate connecting the two flanges is called a web.

[0028] The fixing structure comprises a connecting assembly 1 , and the connecting assembly 1 comprises a first fixing plate 11 , a fastener 12 and a second fixing plate 13 .

[0029] One surface of the second fixing plate 13 is used to connect the air duct, and fasteners 12 are installed at both ends of the other surface of the second fixing plate 13. The first fixing plate 11 is sleeved on the fastener 12, and the first fixing plate 11 and the second fixing plate 13 can be moved closer or farther away from each other by adjusting the fastener 12.

[0030] During use, when the air duct needs to be fixed on the I-beam, first place the second fixing plate 13 below the lower flange of the I-beam, and make the fasteners 12 on the second fixing plate 13 respectively located on both sides of the web of the I-beam. Secondly, make the lower flange of the I-beam between the first fixing plate 11 and the second fixing plate 13. Then, adjust the fasteners 12 so that the first fixing plate 11 and the second fixing plate 13 are close to each other until the first fixing plate 11 is attached to the upper side of the lower flange of the I-beam, and the second fixing plate 13 is attached to the lower side of the lower flange of the I-beam.

It is expected that when removing / adjusting the air duct, there is no need to drill and rivet again, thereby simplifying the construction process and improving work efficiency.

[0032] Example 2

[0033] On the basis of the above-mentioned embodiment 1, Figure 2 As shown, in this embodiment, the middle portion of the first fixing plate 11 is bent in a direction away from the second fixing plate 13, and both ends of the first fixing plate 11 are used to respectively fit on the inner side of the second fixing plate 13 and one flange of the I-beam.

Then, adjust the fasteners 12 so that the first fixing plate 11 and the second fixing plate 13 are close to each other, until the two ends of the first fixing plate 11, which is bent in the middle away from the second fixing plate 13, will be respectively attached to the upper side (inner side) of the lower flange of the I-beam and the second fixed board surface. At this time, the first fixing plate 11 will be subjected to a force in the direction of the second fixing plate 13, and the force will be transmitted to the two ends of the first fixing plate 11. It is expected to achieve the purpose of making the first fixing plate 11 have a certain elastic deformation capacity, which will help to better disperse the stress, so as to improve the stability of the air duct under vertical forces such as earthquakes.

[0036] Example 3

[0037] Based on the above embodiment 2, Figure 2 As shown, in this embodiment, the distance between one end of the first fixing plate 11 and the fastener 12 is greater than the distance between the other end of the first fixing plate 11 and the fastener 12; wherein, one end of the first fixing plate 11 is used to fit on the first fixing plate 11, and the other end of the first fixing plate 11 is used to fit on the inner side of a flange of the I-beam.

[0038] For example, during implementation, one end of the first fixing plate 11 is used to fit on the second fixing plate 13, and the other end of the first fixing plate 11 is used to fit on the upper side of the lower flange of the I-beam. The distance between one end of the first fixing plate 11 and the fastener 12 is greater than the distance between the other end of the first fixing plate 11 and the fastener 12.

[0040] Example 4

[0041] Based on any one of the above embodiments 1 to 3, Figure 2 As shown, in this embodiment, the fastener 12 includes a fastening connecting rod 121 and a fastening ring 122; the fastening connecting rod 121 is connected to the second fixing plate 13; the fastening connecting rod 121 is passed through the first fixing plate 11; the fastening ring 122 is sleeved on the fastening connecting rod 121, and the fastening ring 122 is located on the side of the first fixing plate 11 away from the second fixing plate 13; wherein, when the fastening ring 122 moves along the fastening connecting rod 121 in the direction close to the second fixing plate 13, the fastener 12 is attached to the first fixing plate 11 and drives the first fixing plate 11 to approach the second fixing plate 13.

[0044] When the first fixing plate 11 and the second fixing plate 13 need to be brought closer to each other, the fastening ring 122 is rotated clockwise to bring the fastening ring 122 closer to the second fixing plate 13. At this time, the fastening ring 122 first abuts against the side of the first fixing plate 11 away from the second fixing plate 13, and gradually pushes the first fixing plate 11 to slide along the fastening connecting rod 121 in the direction close to the second fixing plate 13, so as to achieve the purpose of bringing the first fixing plate 11 and the second fixing plate 13 closer to each other.

[0045] When the first fixing plate 11 and the second fixing plate 13 need to be moved away from each other, the fastening ring 122 is rotated counterclockwise to move the fastening ring 122 away from the second fixing plate 13. At this time, the fastening ring 122 will gradually move away from the first fixing plate 11. After the fastening ring 122 moves away from the first fixing plate 11, the first fixing plate 11 is driven to move along the fastening connecting rod 121 in a direction away from the second fixing plate 13. This achieves the purpose of moving the first fixing plate 11 and the second fixing plate 13 away from each other. Through the matching relationship between the fastening ring 122 and the fastening connecting rod 121, it is expected to simplify the installation and adjustment process and improve the construction efficiency.
