Prefabricated roof gutter structure and construction method

Abstract

The present invention discloses an assembled roof gutter structure and a construction method thereof, wherein the waterproof roll material of the side wall of the roof gutter is protected by a prefabricated protective plate, and the roofing cotton layer and the prefabricated protective plate are tied together by a special supporting plate to protect the roll material of the side wall of the gutter, thereby avoiding the risk of traditional protective layer plastering falling off, and avoiding the problem that the waterproof roll material of the side wall of the gutter will produce hollowing and the masonry protection will occupy the width of the drainage ditch. On the other hand, the assembled roof gutter structure and the construction method thereof of the present invention adopt prefabricated protective plates, which are more efficient and shorten the construction period compared to traditional hanging mesh plastering. The present invention solves the problem that in the construction of the roof gutter of a house, the side wall of the waterproof roll material is easy to hollow and the construction process is cumbersome.

Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to an assembled roof gutter structure and a construction method thereof. Background Art

[0002] During roof gutter construction, SBS membranes or TPO membranes are often used for gutter sidewall waterproofing. After the waterproofing is complete, a protective layer is required. A typical method for this protective layer is to hang a wire mesh on the side of the membrane and then apply plastering. Another common method is to lay bricks on the gutter sidewalls to protect the membrane and then apply plastering to the brickwork.

[0003] The conventional ditch sidewall waterproof membrane protective layer can be optimized as follows:

[0004] 1. When hanging wire mesh and then plastering, hollowing often occurs on the side walls of the waterproof membrane (SBS or TPO), and it is very easy to fall off after plastering, especially when the membrane is TPO, the surface of the TPO membrane is extremely smooth and difficult to plaster.

[0005] 2. When using brickwork to plaster the side walls of the ditch, sufficient ditch width must be reserved. Masonry ditch will occupy the original ditch width and affect drainage. When the ditch is located at the cantilevered eaves position, the masonry protective layer will increase the load and affect the structural stress.

[0006] 3. The process of mesh plastering or plastering after masonry is rather complicated, consumes more materials and requires a lot of manpower.

[0007] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.
