Description

Technical Field

[0001] The utility model relates to the technical field of parapet walls, in particular to a fixing structure of a waterproof layer below the flashing of a parapet wall. Background Art

[0002] Roof waterproofing is a crucial component of any construction project, directly impacting both project quality and the building's service life. Parapets offer unique architectural features and waterproofing, and are closely linked to the quality of both roof and exterior wall waterproofing. The parapet flashing refers to the point where the parapet meets the roof, where the roof waterproofing layer connects to the parapet. This area is a crucial component of a building's waterproofing system, and proper treatment directly impacts the building's waterproofing effectiveness and service life.

[0003] There are two main methods for waterproofing below the traditional parapet flashing:

[0004] 1. After the waterproofing membrane below the parapet flashing is completed, the surface of the membrane is roughened with cement glue, and then a wire mesh is hung. Plastering is then carried out simultaneously with the area above the parapet flashing. This method is inconvenient in practice, and the mortar on the waterproofing membrane is prone to falling off, cracking, and hollowing, which significantly affects the subsequent decorative surface.

[0005] 2. After the waterproofing membrane is installed, use fine stone concrete to create fillets within the waterproofing membrane to hold it down, and then apply the decorative layer on top of the fillets. While this method solves the cracking and hollowing problems mentioned in method 1, it is more difficult to construct and requires more materials, significantly increasing costs.

[0006] To this end, Chinese patent authorization publication number CN216276510U currently discloses a parapet and its waterproof structure, which includes a first waterproof layer, a second waterproof layer, a waterproof roll, and a pressure plate. The first waterproof layer is applied to the side wall of the parapet and extends downward from the eaves of the parapet, with a gap between the lower side of the first waterproof layer and the roof. The second waterproof layer is applied to the side wall of the parapet and extends downward from the lower side of the first waterproof layer to the roof. The waterproof roll is applied to the second waterproof layer and extends downward from the lower side of the first waterproof layer to the roof. The pressure plate is fixed to the first waterproof layer, with its lower end extending from the lower side of the first waterproof layer to the outside of the waterproof roll, and the lower end of the pressure plate is sealed with the waterproof roll. However, this patent uses cement nails to fix the waterproof roll, and there is no pressure plate on the outside of the waterproof roll, which makes the waterproof roll easily damaged and detached.

[0037] See also Figures 1 to 8 The fixed structure of the waterproof layer below the flashing of a parapet shown includes a waterproof layer 100, a waterproof membrane 200, a groove structure 300, and a protective plate 400.

[0038] The waterproof layer 100 is provided on the upper portion of the inner wall of the parapet 10 and extends downward from the eaves of the parapet 10 . The waterproof layer 100 in this embodiment is a cement mortar finish.

[0039] The waterproofing membrane 200 is installed on the inner wall of the parapet 10 and extends downward from the lower portion of the waterproof layer 100 to the roof 20. A groove structure 300 is secured to the upper portion of the waterproofing membrane 200 via fasteners 500 that are secured to the parapet 10 and pass through the waterproofing membrane 200. The groove structure 300 secures the upper portion of the waterproofing membrane 200 and prevents it from falling off. The groove structure 300 is provided with a plurality of screw holes 301.

[0040] The top of the protection plate 400 is inserted into the groove structure 300 , and the bottom of the protection plate 400 is fixed to the roof 20 . The protection plate is used to protect the waterproof membrane 200 and prevent the waterproof membrane 200 from being damaged.

[0041] In this embodiment, the grooving structure 300 includes a metal groove with an inverted "U" - shaped cross - section. In order to further improve the fixing effect of the waterproof coiled material 200, a number of anti - slip teeth 310 are provided on the surface of the grooving structure 300 that contacts the waterproof coiled material 200. When the grooving structure 300 is fixed, the anti - slip teeth 310 can press tightly against the waterproof coiled material 200 to prevent the waterproof coiled material 200 from falling off. The anti - slip teeth 310 are arranged along the length direction of the grooving structure 300. In addition, structural adhesive 600 is dot - applied on the surface of the grooving structure 300 that contacts the waterproof coiled material 200. When the grooving structure 300 is fixed, the structural adhesive 600 can bond with the waterproof coiled material 200 to prevent the waterproof coiled material 200 from falling off.

[0042] Preferably, structural adhesive 700 is dot - applied on the surface of the protection board 400 that contacts the waterproof coiled material 200. Since the protection board 400 is a fixed upright structure, the structural adhesive 700 on the protection board 400 can bond with the waterproof coiled material 200 to prevent the waterproof coiled material 200 from falling off, and at the same time prevent the waterproof coiled material 200 from softening and sagging due to too high temperature in summer.

[0043] The top of the protection board 400 in this embodiment is set as an inclined surface structure 410, which is convenient for inserting the top of the protection board 400 into the grooving structure 300. The protection board 400 includes a cement board or a decorative panel. When the protection board 400 is a cement board, putty or paint can be applied after the installation of the cement board to play a decorative role. A temperature expansion joint is provided every no more than 4 m on the cement board, and the expansion joint is sealed with a flexible sealant. The bottom of the protection board 400 is fixed to the roof 20 through marble glue 800. [[ID=??]]

[0044] A sealant 900 is provided between the bottom of the waterproof layer 100 and the grooving structure 200, which can prevent water seepage from entering the parapet wall from the top of the waterproof coiled material 200.

[0045] The roof 20 in this embodiment includes, from bottom to top, a roof structural layer 21, a slope - finding layer 22, a roof waterproof layer 23, a thermal insulation layer 24, and a roof rigid layer 25. The roof waterproof layer 23 and the waterproof coiled material 200 are the same waterproof coiled material, which is convenient for construction.

[0046] Compared with the traditional process, the utility model has the advantages of simple construction, increased efficiency, reduced cost, environmental protection, promoting building industrialization, and practicing the concept of green energy - saving construction. The utility model can prevent problems such as irregular cracks, hollowing, and falling off at the lower part of the parapet wall.
