Description

Technical Field

[0001] The invention relates to the technical field of parapet walls, in particular to a prefabricated roof parapet wall flashing structure and a construction method thereof. Background Art

[0002] In recent years, society and owners have increasingly higher requirements for building waterproofing, which is also a focus of engineering quality. Roof parapet flashing construction and quality control are difficult points in roofing engineering. Traditional construction methods generally use mortar to form an arc-shaped structure at the junction of the roof and the parapet for supporting the laying of waterproof membranes. However, this structural method is time-consuming and labor-intensive to construct, and the ends of the waterproof membranes are difficult to fix, which makes the membranes prone to sliding down. For this reason, the present application proposes a prefabricated roof parapet flashing structure and a construction method thereof. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a prefabricated roof parapet flashing structure and a construction method thereof, so as to solve the problem that the existing structural method is time-consuming and labor-intensive during construction, and the ends of the waterproof roll are difficult to fix, and the roll is prone to sliding down.

[0004] The present invention provides a prefabricated roof parapet flashing structure, and its technical solution is as follows: it comprises: a bracket installed at the connection between the roof slab and the parapet, the bracket being arranged along the entire length of the parapet; a supporting plate obliquely arranged on the bracket, the supporting plate covering the connection between the roof slab and the parapet; a waterproof coiled material installed on the supporting plate; a pad and a cover plate installed on the bracket for clamping and fixing the upper end of the waterproof coiled material.

[0005] Furthermore, the bracket includes a horizontal portion and a vertical portion, the horizontal portion is buried in the roof floor, and the end of the vertical portion is fixedly connected to the inner side of the parapet.

[0006] Furthermore, one end of the support plate is connected to the upper end of the vertical portion of the bracket, and the other end is connected to the front end of the horizontal portion of the bracket and is flush with the roof floor.

[0007] Furthermore, the cover plate is U-shaped and is clamped with an end of the cushion block away from the parapet.

[0008] Furthermore, a limiting strip is provided on the inner side of the cover plate, and the limiting strip is arranged along the entire length of the cover plate, and a limiting groove matching with the limiting strip is provided on the upper end surface of the cushion block.

[0009] The present invention also provides a construction method for a prefabricated roof parapet flashing structure, and the specific construction steps are as follows: assemble and install the bracket at a designated position; install a support plate on the bracket; install the cushion block on the upper end of the bracket, place the upper end of the waterproof membrane on the cushion block, buckle the cover plate on the cushion block to fix the waterproof membrane; install the waterproof membrane on the support plate.

[0010] Furthermore, when the roof slab is cast, the horizontal portion of the bracket is buried in the roof slab so that the horizontal portion of the bracket is flush with the roof slab.

[0011] Furthermore, when installing the support plate, one end of the support plate is fixedly connected to the upper end of the vertical portion of the bracket, and the other end is fixedly connected to the front end of the horizontal portion of the bracket.

[0012] Furthermore, when the cover plate is buckled onto the cushion block, the limiting strip on the cover plate is engaged with the limiting groove on the cushion block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting up a bracket and a support plate, the waterproof membrane can be fixed on the support plate. Compared with the traditional structure formed by mortar casting, the construction of this structure is more time-saving and labor-saving. By setting up a pad and a cover plate, the pad and the cover plate can clamp and fix the end of the waterproof membrane to prevent the waterproof membrane from falling off, and at the same time can also seal the end of the waterproof membrane to prevent rainwater from entering the bracket from the end of the waterproof membrane.

[0015] By setting the cover plate and the supporting plate in an inclined state, rainwater on the cover plate can quickly slide onto the supporting plate and slide onto the roof floor along the inclined supporting plate, thereby preventing rainwater from staying on the device for a long time.
