Description

Technical Field

[0001] The utility model relates to the technical field of parapet metal cover plates, in particular to a double waterproof parapet metal cover plate for exterior wall construction. Background Art

[0002] A parapet (also known as a granddaughter wall) is a low wall surrounding a building's roof, primarily used for security. In some buildings, decorative structures are installed on top of the parapet to enhance the overall aesthetics of the building. These structures serve as rainwater drainage canopies and also enhance the structural aesthetic.

[0003] Traditional metal cover installation typically involves cumbersome steps, including setting out the parapet top, drilling holes in the wall, embedding and securing the panels, welding brackets, and finally installing the panels. The installation process requires metal expansion bolts, embedded panels, fixing brackets, metal covers, and sealant, resulting in high material costs. Traditional cover panels also have room for improvement. Rigid joints lack stress relief and are prone to deformation due to temperature fluctuations. Aging sealant at the joints allows rainwater to enter the cover. Perforations at the parapet top create the risk of leakage. Internal cavities form, creating a "whirring" sound when wind blows. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, a double waterproof parapet metal cover plate for exterior wall construction is proposed to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

[0007] As a further technical solution of the present invention: the connecting part one includes an expansion sealing strip attached to the inner wall of the metal cover body, and a baffle one is fixedly arranged at one end of the metal cover body close to the expansion sealing strip to block the expansion sealing strip; the connecting part two includes a groove for accommodating the expansion sealing strip, the groove includes a baffle two fixedly arranged at one end of the metal cover body and corresponding to the baffle one, a support plate extends from the inner side of the baffle two away from one end of the baffle two, and an extrusion plate extends from the support plate away from one end of the baffle two.

[0008] As a further technical solution of the present invention: the extrusion plate and the baffle plate 1 cooperate with the compression and expansion sealing strip, a gap is formed between the baffle plate 2 and the support plate, the gap is filled with a foam strip, and there is sealant on the outside of the foam strip.

[0009] As a further technical solution of the present invention: a plurality of nails are arranged at intervals in the nail fixing groove, and sealant is provided on the outside of the nails.

[0010] As a further technical solution of the present invention: the inner sides of the top and side edges of the cover plate are parapets, and the inner sides of the folded edges and the nail fixing grooves are close to the parapets.

[0011] As a further technical solution of the present invention: a drip edge is formed at the connection between the folded edge and the side edge of the cover plate.

[0012] Beneficial effects of the utility model:

[0013] The side edge of the cover plate of the utility model is provided with a nail fixing groove, and the metal cover plate body is fixed to the parapet with nails, and sealant is applied on the outside of the nails.

[0015] The extrusion plate and the baffle plate cooperate with the compression expansion sealing strip to form a gap between the baffle plate 2 and the support plate. The gap is filled with a foam strip, and there is sealant on the outside of the foam strip. The foam strip and the sealant form the first waterproof sealing treatment, and the expansion sealing strip forms the second waterproof sealing treatment; if the sealant at the joint is aged, the compressed expansion sealing strip can play a waterproof role and avoid leakage.

[0016] There are no holes punched on the top of the cover plate, which makes it less likely to produce upward seams, thus preventing water from entering the top and causing alkali backflow and leakage on the wall. The side edges and middle nail fixing grooves of the cover plate are close to the wall, forming an integral part with the wall, making the fixation more secure. There is no through cavity inside, and no noise will be generated in windy weather. BRIEF DESCRIPTION OF THE DRAWINGS
