Description

Technical Field

[0001] The utility model relates to the field of roof waterproofing, in particular to a concealed roof parapet flashing structure. Background Art

[0002] In construction projects, the flashing design of the roof parapet wall plays a pivotal role. As a low wall at the edge of the building roof, the parapet wall not only plays a role of safety protection to prevent people from accidentally falling, but also plays a key role in waterproofing the top to ensure that rainwater does not penetrate into the room from the top of the wall.

[0003] However, the current parapet flashing design faces many challenges. The traditional practice is to lay waterproof membrane on the brick parapet as a waterproof layer and brush a layer of mortar on it for protection. Although this structure can play a waterproof role to a certain extent, it has obvious shortcomings. First of all, the flashing part usually protrudes 30mm-50mm from the parapet, which not only affects the overall appearance of the building, but also may cause cracks in the wall due to thermal expansion and contraction during daily use. More seriously, as time goes by, the waterproof membrane may age, fall off, bulge and crack. Once these problems occur, the waterproof layer will fail, causing the roof to leak, which may cause more serious damage. This not only affects the normal use of the building, but also may cause inconvenience and safety hazards to the residents. Utility Model Content

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0023] The flashing of the parapet 4 used in the prior art has the problem of failure of the waterproof layer. In this regard, a concealed roof parapet flashing structure is provided in this embodiment. The flashing wall 7 and the protective wall 2 are used to establish a protective structure for the folded edge area of ​​the waterproof membrane 6. The gap between the flashing wall 7 and the protective wall 2 accommodates the folded edge area of ​​the waterproof membrane 6 to reduce the exposure of the waterproof membrane 6, realize a concealed structure, and ensure the quality and stability of the waterproof layer. The parapet 4 is arranged above the flashing wall 7 and the protective wall 2, so that the flashing of the parapet 4 plays its due role in the construction project, providing a solid guarantee for the waterproof safety and overall aesthetics of the building.

[0024] like Figure 1 As shown, the concealed roof parapet flashing structure includes a flashing wall 7, a waterproof membrane 6 and a protective wall 2. The flashing wall 7 is a structure cast on the roof edge structural beam 8, and adopts a reinforced concrete structure with a thickness of 120mm-150mm. At the same time, a protective wall 2 is also provided above the roof. The protective wall 2 is located on the side of the flashing wall 7 close to the internal structure of the building, and the protective wall 2 and the flashing wall 7 are spaced apart in the horizontal direction, and the outer facade of the protective wall 2 is flush with the outer facade of the building structural beam 8.

[0025] The waterproofing membrane 6 is laid on the roof and its edge is folded upward along the flashing wall 7. The folded portion of the waterproofing membrane 6 is located between the protection wall 2 and the flashing wall 7, and is respectively attached to the protection wall 2 and the flashing wall 7.

[0026] The flashing wall 7 with reinforced concrete structure can enhance the overall structural strength and waterproof performance of the roof 1, and ensure the quality and durability of the wall. After pouring, the flashing wall 7 will be fully maintained to ensure that it reaches the designed strength.

[0027] In this embodiment, waterproofing membrane 6 is laid on the inner facade of roof 1 and flashing wall 7. The waterproofing membrane 6 has multiple layers. During the laying process, it is ensured that the waterproofing membrane 6 is flat and wrinkle-free, and the overlapping width of the waterproofing membrane 6 meets the requirements of industry specifications, thereby forming an effective waterproof layer to protect the building from moisture.

[0028] like Figure 1 As shown, after a gap for accommodating the waterproof membrane 6 is formed between the protection wall 2 and the flashing wall 7, the top of the gap is exposed. In order to prevent external water from penetrating into the gap, a closing block 3 is provided at the top of the protection wall 2. The closing block 3 extends toward the flashing wall 7 and is connected to the flashing wall 7, thereby blocking the top of the gap between the protection wall 2 and the flashing wall 7.

[0029] like Figure 1 As shown, the closing block 3 is connected to the side of the flashing wall 7, so that the closing block 3 can block the top of the gap between the protection wall 2 and the flashing wall 7, and the top surface of the closing block 3 is flush with the top surface of the flashing wall 7, so that its top surface forms a flat plane, which is convenient for arranging the parapet 4. A parapet 4 is provided above the top surface of the closing block 3 and the top surface of the flashing wall 7, and the outer side surface of the parapet 4 is flush with the outer side surface of the flashing wall 7, and the inner side surface of the parapet 4 is flush with the inner side surface of the protection wall 2.

[0030] In this embodiment, solid bricks are used to build the parapet wall 4 on the plane formed by the top of the flashing wall 7. The wall thickness of the parapet wall 4 will be equal to the distance between the outer facade of the flashing wall 7 and the outer facade of the protection wall 2. Not only the stability of the parapet wall 4 is ensured, but also it is coordinated with the overall architectural style and improves the aesthetics of the building.

[0031] The folded edge of the waterproof membrane 6 is fixed to the flashing wall 7 by the anchor 5 , and the connection position between the anchor 5 and the flashing wall 7 is located below the closing block 3 . In this embodiment, the anchor 5 is located at the top of the folded edge of the waterproof membrane 6 .

[0032] The anchor 5 can be cement nails or nails and galvanized gaskets. The upper end of the bending area of ​​the waterproof membrane 6 is sealed with cement nails or nails and galvanized gaskets to ensure that the sealing is firm and sealed to prevent moisture from penetrating from the sealing, thereby further enhancing the waterproof effect.

[0033] The protection wall 2 is located above the waterproofing membrane 6 laid on the roof 1. In this embodiment, the protection wall 2 is built with solid bricks. The inner facade of the protection wall 2 is close to the waterproofing membrane 6 and presses it against the flashing wall 7. The waterproof layer composed of the waterproofing membrane 6 can be effectively protected from external damage. At the same time, the horizontal thickness of the flashing wall 7 is greater than the horizontal thickness of the protection wall 2 to ensure the stability of the flashing wall 7. The height of the protection wall 2 does not exceed the height of the flashing wall 7, and the closing block 3 fills the top of the protection wall 2 to ensure that the waterproofing membrane 6 is fully protected. In this embodiment, the closing part is made of polymer cement mortar.

[0034] The surface layer of the roof 1 is filled between the waterproofing membrane 6 and the roof, and its structural form usually depends on the design requirements of the building, the climatic conditions of the location, and the expected use function. The surface layer of the roof 1 includes a cement mortar leveling layer, a thermal insulation layer, and a waterproof layer. The cement mortar leveling layer is mainly used to level the roof surface and provide a good foundation for the subsequent waterproofing layer construction; the thermal insulation layer is usually composed of thermal insulation materials, such as polystyrene foam board, rock wool, etc., and its function is to reduce the transfer of heat on the roof and improve the thermal insulation performance of the building; the waterproof layer is directly covered on the waterproofing membrane 6 to enhance the waterproof performance of the roof 1. The waterproof layer can be made of a variety of materials, such as waterproof coatings, waterproof membranes, etc., and is selected according to specific design requirements and construction conditions. The waterproofing membrane 6 can also be used as a component of the waterproof layer.

[0035] The top edge of the roof is arranged at an angle to form a drainage slope to promote roof drainage.

[0036] Through multiple measures such as reinforced concrete flashing wall 7, waterproof membrane 6, upper end treatment of waterproof membrane 6, protection wall 2 and parapet 4 masonry, the waterproof performance of roof 1 and the aesthetics of the building are comprehensively improved, providing a more efficient and practical solution for modern buildings.
