Folded edge flashing structure and construction method for roof

Abstract

The invention discloses a folded-edge flashing structure for a roof and a construction method thereof. The structure comprises flashing plates, each two adjacent left and right flashing plates on a same straight lineare fixedly connected, a supporting structure is arranged between each two adjacent left and right flashing plates, and each two adjacent front and rear flashing plates on a same straight line are hermetically connected. The construction method includes: (a), preparing the flashing plates; (b), constructing a roof bottom plate; (c), constructing heat-insulating cotton and a roof upper-layer plate; (d), mounting a base and a supporting structure; (e), splicing the flashing plates mutually; (f), mounting and constructing the flashing plates; (g), on-sitecleaning; (h), performingwaterproof testing on the flashing plates. By the folded-edge flashing structure, front-rear left-right adjacent two flashing plates are ensured to be mounted orderly, so that appearance attractiveness of the roof is improved; the flashing plates are spliced, then the flashing plates are integrally mounted and transversely arranged according to a sequence from rear to front, so that construction efficiency of the flashing plates is improved, mounting accuracy of the flashing plates is improved, sealability of the flashing plates after construction is improved, and waterproof effect is promoted.

Description

technical field [0001] The invention belongs to the technical field of flashing construction, and in particular relates to a folded-edge flashing structure and a construction method for roofs. Background technique [0002] Flashing, that is, the waterproof structure between the roof waterproof layer and the protruding structure. The junction of the wall and the roof such as the parapet, chimney, stairwell, deformation joint, manhole, riser, etc. protruding above the roof extends the roof waterproof layer to these vertical surfaces to form a vertical waterproof layer, which is called Flashing. Flooding is a kind of waterproof process in buildings. In layman's terms, it is actually the waterproof treatment performed on the walls and roofs, that is, at the intersection of all flat and vertical surfaces that need waterproof treatment. To put it bluntly, it is to wrap the corners of the walls with waterproof materials. Unlike bulk water, flashing is a waterproof structure that ...

AI Technical Summary

Problems solved by technology

This construction and installation method exposes the sealant to the outside for a long time, and it will quickly fail after being exposed to wind and sun, resulting in water leakage. Moreover, it is difficult to ensure that the flashing board is horizontal and vertical during the construction process, which affects the appearance of the roof.
