The utility model provides a subway station rail top wind channel, including medium plate 1, the downside of medium plate 1 is connected with wind channel main part 2. As shown in fig. 1, the duct main body 2 is a box structure having openings at both ends.

The middle plate 1 is connected with the air duct main body 2 through the embedded bolts 5, as shown in fig. 2 and 4, the embedded bolts 5 are arranged on the lower side of the middle plate 1, and the embedded bolts 5 are installed in the pouring process of the middle plate 1. The screw rods of the embedded bolts 5 extend downwards, penetrate through the air duct main body 2 and are fixed on the air duct main body 2 through double nuts 6. The purpose that two nuts 6 set up is locking, prevents that subway vibrations from making the nut not hard up.

In order to realize the connection between a plurality of air duct main bodies 2, the two sides of the air duct main bodies 2 are connected with installation parts 3, and the installation parts 3 are arranged along the length direction of the air duct main bodies 2. Use the connection between the installation department 3, can indirectly connect two adjacent wind channel main parts 2, make a plurality of wind channel main parts 2 constitute that the rail pushes up the wind channel wholly, avoid traditional monolithic pouring and the problem that the steel bar connection mounting means is inefficiency, the construction work is big.

As shown in fig. 1, the air duct main body 2 includes an air duct top plate, an air duct bottom plate, and two air duct side plates on two sides, and the air duct top plate, the air duct bottom plate, and the two air duct side plates jointly form the air duct main body 2. The air duct top plate, the air duct bottom plate and the air duct side plates in the embodiment are of an integrated structure. The air duct top plate is connected with the middle plate 1 through the embedded bolt 5.

As shown in fig. 3 and 5, the mounting portion 3 has a strip structure, and a groove 31 is opened at the top of the mounting portion 3. A plurality of fixing pieces 4 are pre-buried on the middle plate 1, the fixing pieces 4 are also installed in the pouring process of the middle plate 1, and the bottoms of the fixing pieces 4 protrude out of the middle plate 1. The shape of the fixing piece 4 is matched with that of the groove 31, and then the fixing piece 4 is clamped in the groove 31 to realize the connection of the mounting part 3 and the middle plate 1. Since the width of the middle of the groove 31 is smaller than the width of the two ends of the groove 31 in this embodiment, the fixing member 4 is not easy to fall off after being clamped.

Specifically to the fixing member 4, the fixing member 4 includes a catching portion 41. The clamping portion 41 is arranged on one side of the fixing member 4 close to the air duct main body 2, and the clamping portion 41 is clamped at the bottom of the groove 31.
