In this embodiment, a part of the shielding member 331 is used as the transition step 212, and the ascending step 211, the shielding member 331 and the descending step 213 are connected to form the passage way 24 to cover the water leakage preventing structure 30. The arrangement is to provide the ascending step 211 and the descending step 213 with reference to the height of the water leakage preventing structure 30 while saving materials, so as to facilitate walking through the water leakage preventing structure 30. It will be appreciated that the passage way 21 may be additionally provided to the transition step 212 when the shield 331 is not able to carry a walk through. The transition step 212 is disposed above the shield 331 in the third direction S3. The transition step 212 may be made of reinforced concrete or metal with a certain strength, such as a steel structural platform. It is understood that the structures, sizes and materials of the ascending step 211, the transition step 212 and the descending step 213 are not limited as long as the stepping through at the time of walking can be achieved, and specifically, the ascending step 211 and the descending step 213 may be hollow structures or solid structures.

Typically, the length of the intercepting ditches in the second direction S2 is 300mm, and the preset interval L should be not less than 300mm. Further, the preset interval L is not greater than the number obtained by multiplying the height of the tread unit 21 in the third direction S3 by the length of the street in the second direction S2, dividing by the height of the building in the third direction S3, and adding 200 mm. The arrangement of the preset interval L can enable the second protection piece 22 in the sight line to be shielded by the first protection piece 10 when the building is observed, so that the consistency of the first protection piece 10 is ensured, the integrity and the aesthetic property of the building free face are improved, and the straight and neat building vertical face is realized. In one possible embodiment, the first guard 10 at the void may then cover the second guard 22 on the roof 41 from the outermost side to the inner side of the street.

The roofing structure of claim 1 wherein the water leak prevention structure includes a reverse ridge assembly extending through the deformation joint and at least partially protruding from the roofing, the reverse ridge assembly configured to block fluid falling on the roofing from flowing into the deformation joint.

5. The roofing structure of claim 4 wherein the back ridge assembly includes first and second back ridges spaced apart in a first direction and connected to the side walls of the deformation joint on a side thereof facing away from each other; wherein the first direction is parallel to the seam width direction of the deformation seam;

the water leakage prevention structure further comprises a waterproof component, wherein the waterproof component covers the outer side of the first reverse ridge, a gap between the first reverse ridge and the second reverse ridge and the outer side of the second reverse ridge.

6. The roofing structure of claim 1 wherein the pass assembly further comprises a tread unit overlying the water leak resistant structure and a second guard on at least one side of the tread unit, the tread unit and the second guard defining the pass aisle.

7. The roofing structure of claim 6 wherein in the first direction, the distance between the tread element and the roofing surface in a third direction increases gradually and then decreases gradually;

the third direction is perpendicular to the roof.

8. The roofing structure of claim 7 wherein the tread element comprises an ascending step, a transition step, and a descending step connected in sequence along the first direction;

the height of the transition step along the third direction is higher than the height of the ascending step along the third direction and higher than the height of the descending step along the third direction.

9. The roofing structure of claim 8 wherein a side surface of the transition step facing away from the roofing is parallel to the roofing; and/or

The step surface of the ascending step is parallel to the roof; and/or

The step surface of the descending step is parallel to the roof.

10. The roofing structure of claim 1 wherein the first guard extends in a thickness direction of the roof.
