[0016] See also Figure 1 to Figure 3 In an embodiment of the utility model, a mining steel structure storage warehouse includes an embedded part 1 buried in concrete, a steel structure 2 is fixedly installed on the top of the embedded part 1 through a flange, the tops of two adjacent steel structures 2 are connected to the same top beam 3 through flanges, connecting ears 4 are welded to the outer periphery of the embedded part 1 and the top beam 3, and the inner wall of the connecting ear 4 located at the same height in the front and rear directions is plugged with the same fixing rod 5, and an exhaust mechanism is installed on the web portion of the front and rear connected steel structures 2.

[0017] In this embodiment: first, the embedded part 1 is fixed in the pit, and the embedded part 1 is fixed by pouring concrete, and then the steel structure 2 is placed on the top of the embedded part 1 and fixed with the embedded part 1. After the corresponding steel structures 2 and embedded parts 1 on the left and right sides are fixed, the top beam 3 is fixed on the top of the two steel structures 2. After the top beam 3 and the steel structure 2 are assembled, the connecting ears 4 are welded to the outer walls of multiple steel structures 2 and the top beam 3. After welding, the fixing rod 5 is inserted into the inner wall of the connecting ear 4 at the same height and in the same length direction. After the fixing rod 5 is inserted, the fixing rod 5 is welded to the connecting ear 4. Finally, the exhaust mechanism is installed between the webs of each steel structure 2.

[0018] Please refer to Figure 2 and Figure 3 The exhaust mechanism includes a circular hole 10 opened on the web of the steel structure 2, and docking flanges 7 are fixedly installed at both ends of the web of the steel structure 2 and aligned with the circular hole 10 through bolt holes. The exhaust mechanism also includes an exhaust steel pipe 6 connected between the two oppositely arranged docking flanges 7, the inner cavity of the exhaust steel pipe 6 is connected to the inner cavity of the circular hole 10, and the inner diameter of the exhaust steel pipe 6 is equal to the inner diameter of the circular hole 10; the exhaust mechanism also includes an air pump, which is plugged and fixed to one end of the exhaust steel pipe 6 through an air pipe and a detachable pipe joint.

[0019] In this embodiment: a docking flange 7 is installed on the circular hole 10 of the web portion of the fixed steel structure 2, and the docking flange 7 is fixed, at which time the exhaust steel pipe 6 can be fixed; then the other end of the exhaust steel pipe 6 is installed on the circular hole 10 of another adjacent steel structure 2 in front and behind by the same bolt and nut fixing method.
