The second vapor barrier layer Cover the top layer of additional purlins, install sliding fixed supports on the top layer of additional purlins, and the sliding fixed supports support the roof panels. The roof panels adopt a 360° vertical lock seam structure at the slidable fixed supports, and the lock seams are pre-injected. , seal the roof after seaming.

In the system, the compartment frame and the slidable fixed support are alternately distributed in the roof system.

In the above system, the roof system adds thermal insulation pads at the position of the slidable fixed support to prevent cold bridge phenomenon.

In the system, a few-shaped compartment frame is connected to the structural bottom plate.

In the system described above, the structural bottom plate is fixed on the structural purlins with self-tapping screws.

In the system described above, the additional purlins are fixed on the compartment frame with self-tapping screws.

Compared with the prior art, the utility model has the beneficial effects that:
