[0019] The utility model will be further described below in combination with the drawings and examples.

[0020] Referring toFigures 1-5 A smoke exhaust duct structure for fire protection engineering includes two first plates 10 spaced horizontally apart and two second plates 30 spaced vertically apart. A plurality of fixed frames 20 are arranged between the two first plates 10 along a front-to-back direction. The first plates 10 are detachably connected to the fixed frames 20. The left and right sides of the second plates 30 are detachably connected to the first plates 10. A sealed mounting cavity 70 is provided on the inner side of the connection between the first plates 10 and the second plates 30, and a sealing strip 40 is provided inside the sealed mounting cavity 70. This utility model eliminates the use of existing plug-in components, effectively reducing the number of parts and lowering production costs. Simultaneously, this utility model provides a sealed mounting cavity, and the sealing strip is inserted into the sealed mounting cavity to achieve a seal, enhance sealing performance, and prevent air leakage.

[0021] Further, see Figure 5 The sealing strip 40 is clamped and fixed between the first plate 10, the second plate 30 and the fixing frame 20.

[0022] During assembly, the two first plates 10 on the left and right are firstly fixedly connected to the fixed frame 20. Then, the sealing strip 40 is inserted into the sealing mounting cavity 70 near the connection point between the first plate 10 and the second plate 30. In this state, the sealing strip 40 is clamped and fixed by the first plate 10 and the fixed frame 20. Then, the two second plates 30 on the top and bottom are connected to the first plate 10. Finally, the second plates 30 are locked to the fixed frame 20.

[0023] See Figure 4 The fixed frame 20 has a first threaded hole 210 on the side near the sealed mounting cavity 70, and a positioning bolt 50 is threaded into the first threaded hole 210. The sealing strip 40 has a positioning hole 410 corresponding to the position of the first threaded hole 210, and the positioning bolt 50 is movably inserted into the positioning hole 410. In this embodiment, the function of the positioning bolt 50 is to constrain the sealing strip 40. Since the sealing strip 40 is inserted into the sealed mounting cavity 70 in a front-to-back insertion manner, this positioning insertion can constrain the front-to-back movement of the sealing strip 40, preventing it from moving and affecting the sealing performance.

[0024] See Figure 4The first plate 10 has insertion slots 120 on its upper and lower sides, and the second plate 30 has bending inserts 300 on its left and right sides. The bending inserts 300 are movably inserted into the insertion slots 120. When the second plate 30 is connected to the first plate 10, it is assembled by inserting the second plate 30 into the first plate 10 in a front-back direction. During insertion, the bending inserts 300 are inserted into the insertion slots 120, effectively restraining the left-right and up-down movement of the second plate 30. The front-back movement restraint of the second plate 30 relies on a fixed connection between the second plate 30 and the fixed frame 20.

[0025] See Figure 3 The fixing frame 20 has first mounting holes 200 on its left and right sides. The first plate 10 has a second mounting hole 100 communicating with the first mounting holes 200. A locking bolt 610 passes through the first mounting hole 200 and extends to the outside of the first plate 10. A locking nut 620 is provided on the outside of the first plate 10, and the locking nut 620 is threadedly connected to the locking bolt 610. The locking nut 620 abuts against the outer wall surface of the first plate 10, and the bolt head of the locking bolt 610 abuts against the fixing frame 20. The locking nut 620 and the bolt head cooperate to clamp and fix the fixing frame 20 and the first plate 10.

[0026] See Figure 2 The fixed frame 20 has second threaded holes 220 on its upper and lower sides, and the second plate 30 has a third mounting hole 310 communicating with the second threaded holes 220. A fixing bolt 80 passes through the third mounting hole 310 and is threadedly connected to the second threaded hole 220. This connection can constrain the front and rear position of the second plate 30, thereby connecting the first plate 10, the fixed frame 20, and the second plate 30 together.
