[0022] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0023] Example 1

[0024] A type of rectangular duct seismic support, such as Figures 1-3 As shown, the system includes at least two threaded rods 1 and a first C-shaped channel steel 2 and a second C-shaped channel steel 3 fixed between the two threaded rods 1. The space between the first C-shaped channel steel 2 and the second C-shaped channel steel 3 is the installation space for a rectangular duct 4. The threaded rods 1 are fixed to the floor deck by seismic anchor bolts 5. A stiffening device is also provided above the first C-shaped channel steel 2 and on the threaded rods 1. The stiffening device includes a C-shaped channel steel 13 and an Ω-shaped pressure block 9. The C-shaped channel steel 13 is sleeved on the threaded rods 1. The fully threaded screw 1 is secured to the C-shaped channel steel 13 by an Ω-shaped pressure block 9. The Ω-shaped pressure block 9 includes a pressure block body 91, a screw 92, and a baffle 93. The pressure block body 91 is Ω-shaped, and the screw 92 is a double-stage screw, including a coarse screw threaded to the baffle 93 and a fine screw for limiting the pressure block body 91. The opening diameter of the elliptical top of the pressure block body 91 is smaller than that of the coarse screw but larger than that of the fine screw. The fine screw passes through the opening and is fixed by double nuts to limit the pressure block body 91. The two double nuts are fixed on both sides of the pressure block body 91, mainly serving to limit and not fix the pressure block body 91, which can rotate freely on the screw.

[0025] Except for the hanger rod, the main support structure of this application is made of C-shaped channel steel. The bottom plate of the C-shaped channel steel should be provided with bolt holes (elliptical holes) at even intervals, and the side plates should be provided with rolled edges. The side plates should also be provided with bolt holes at intervals as needed. Specifically, the back plates of the first C-shaped channel steel 2 and the second C-shaped channel steel 3 are provided with elliptical holes at even intervals, and the slots are all facing downwards. The bottom surface of the first C-shaped channel steel 2 and the top surface of the second C-shaped channel steel 3 are both fixed with rubber gaskets 7 by screws 6.

[0026] Example 2

[0027] Based on Embodiment 1, an anti-seismic brace 12 is also provided between the first C-shaped channel steel 2 and the floor deck. The upper and lower parts of the anti-seismic brace 12 are connected and fixed to the floor deck and the first C-shaped channel steel 2 through anti-seismic connecting seat A10 and anti-seismic connecting seat B11, respectively. The anti-seismic brace 12 is made of C-shaped channel steel. Two teeth 94 are provided on the plate surface of the baffle 93 facing the outside of the C-shaped channel steel 13 on both sides. The teeth 94 are used to limit the two rolled edges of the C-shaped channel steel 13. When the screw 92 is rotated, the baffle 93 can be made to remain stationary relative to the C-shaped channel steel 13, so that the end of the screw can be deeply abutted against the fully threaded screw.

[0028] Example 3

[0029] Based on Embodiment 2, the two sides of the rectangular duct 4, the bottom surface of the first C-shaped channel steel 2, and the second C-shaped channel steel 3 are respectively provided with limiting threaded rods 8. The upper and lower parts of the limiting threaded rods 8 pass through the elliptical holes and are fixed by nuts. The rods of the threaded rod 1 that pass through the top of the first C-shaped channel steel 2 and the bottom of the second C-shaped channel steel 3 are limited by U-shaped pressure blocks and nuts. The Ω-shaped pressure block 9 includes a central arc structure and folded edges on both sides of the central arc structure. In specific use, the diameter of the threaded rod relative to the central arc structure determines whether the threaded rod is positioned by the central arc structure or by a combination of the central arc structure and the end of the second-order screw.
