When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

The present invention will be further explained with reference to fig. 1 to 8:

the first embodiment is as follows:

as shown in fig. 1 to 4, the air duct of this embodiment includes an upper air duct 1 and a lower air duct 2 connected to each other, the upper air duct 1 is formed by connecting an upper air duct box 11, 3L-shaped angle steel members 12 and 1L-shaped angle steel member 13, and the lower air duct 2 is formed by connecting a lower

air duct box

21, 3 groove structural members 22 and 1L-shaped angle steel member 23. And flanges which are turned outwards are arranged at the connecting ports of the upper air duct box body 11 and the lower air duct box body 21. The L-shaped

angle steel pieces

12 and 13 are fixed on the upper air duct box body 11 in a rivet connection mode. The groove structural member 22 and the L-shaped angle steel member 23 are fixed to the lower duct box 21 by means of rivet connection. Because the space is narrow during the installation, trilateral there is shear force wall 3, the tradition directly piles up the mode on tuber pipe box down with last tuber pipe box, can increase inboard fixing bolt's the degree of difficulty, in this embodiment, it directly pushes tuber pipe 2 upsides down by groove structure 22's groove position from the side direction to go up tuber pipe 1, wherein the fixed laminating of L type angle steel spare 12 in the tuber pipe is gone up in groove structure spare, the last tuber pipe L type angle steel spare 13 and the tuber pipe L type angle steel spare 23 of tuber pipe pass through bolt fixed connection down that leans on outer one side.

As shown in fig. 5-8, joint strip is all installed to upwind pipe flange downside and downwind pipe flange upside, and adhesive tape thickness is 2.5mm, notices when the adhesive tape pressure-bearing real-time, and thickness will change into 2mm, groove structure spare 22 is fixed in down tuber pipe box 21 through rivet connection's mode, and its inside II groove width is 0.5mm than L type angle-bar spare 12 is big, adopts clearance fit's mounting means. As shown in fig. 7-8, unlike the L-shaped angle member 12, the angle member 13 has several oblong through holes on its horizontal end surface for connecting with the downpipe 2, and in this embodiment, the L-shaped angle member has a thickness of 3mm, which ensures the tight connection between the angle member and the wall of the ducted box.
