[0014] The embodiments of the utility model will be described in detail below with reference to the drawings. DETAILED DESCRIPTION

[0015] The utility model will be further described below in combination with the drawings and embodiments:

[0016] As Figure 1 shown, a roof protection layer partition gap filling air bag, comprising: a plurality of air bags 1, a plurality of iron strips 2, a plurality of metal kits 3, the main body shape of air bag 3 is rectangle, the upper surface of air bag 1 is provided with inflatable valve 4, the both sides of air bag 1 are fixedly connected with two iron strips 2 through gluing, one air bag 1 and two iron strips 2 form an inflatable structure, the metal kit 3 is cross type sleeve pipe, and the both ends of the inflatable structure can be inserted into the sleeve opening of the metal kit 3.

[0017] Specifically, after air bag 3 is inflated, the shape of the inflatable structure is long strip, to adapt to the common form of roof partition gap, the size and shape of the air bag can be flexibly adjusted according to the width and shape of the actual partition gap, and only the inflatable amount needs to be changed to realize close fitting, the inflatable structure is combined with the metal kit 3, and is used for the construction of the intersection part of the partition gap.
