Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to a roof flashing waterproof protection structure. Background Art
[0002] In the field of construction, the flashing is the key waterproof area where the roof and the wall meet, and its main function is to prevent rainwater from penetrating into the building. However, the existing construction methods of roof flashing waterproof protective layers have some common quality problems, which seriously affect the waterproof performance and service life of the building.
[0003] In the prior art, there are usually two methods for constructing the flashing waterproof protective layer of the roof. The first method is: adopt the same method as the exterior wall decoration, after the waterproof layer is constructed, use mortar plastering as a protective layer, and construct a finishing layer thereon. Since the surface of the waterproof layer is usually relatively smooth, the bonding effect between the plastering and the waterproof layer is not good, and it is easy to have quality problems such as hollowing, cracking, or even falling off of the plastering protective layer in the near future. This not only makes it difficult to meet the acceptance standards, but also brings hidden dangers to the handover and use of the building, and increases the maintenance cost. The second method is: use brickwork as the flashing waterproof protective layer, and then construct mortar plastering and surface finishing. Although this method improves the protective effect of the waterproof layer to a certain extent, it is not conducive to the appearance or structural design of the roof parapet and the exterior wall, and it may also reduce the available roof area and limit the utilization efficiency of the building space.
[0004] After searching, the existing Chinese utility model application document with announcement number CN212224363U discloses a slope roof flashing connection structure, "including a wall, a roof panel, an insulation layer, a waterproof board, a tile, an additional waterproof layer, a flashing board, a sealant layer, a water-shedding board, and a plastering layer; the roof panel and the inner side of the wall are laminated with an insulation layer, the insulation layer surface on the roof panel is laminated with a waterproof board, the waterproof board is fixed with a tile hanging strip by steel nails, the tile hanging strip is hung and fixed with a tile, and a full-length flashing board is provided at the junction of the tile closest to the wall and the wall; one end of the flashing board is fixed to the wall with a plastic expansion bolt, the middle part covers the junction of the tile and the wall in a sloped structure, and the other end is overlapped On the tile, the flashing board is fixed while one end of the additional waterproof layer is also fixed. The other end of the additional waterproof layer is attached to the surface of the insulation layer and extends downward between the tile and the waterproof board. The width of the two ends should be greater than 300mm. The additional waterproof layer and the end of the flashing board are sealed with a full-length sealant layer. However, the structure involves multiple layers and components. Although it can provide good waterproofing effects, it also increases the complexity and difficulty of construction. It requires precise construction technology and strict quality control to ensure that each layer is properly installed and sealed. At the same time, due to the complex structure, more manpower and time may be required during the construction process, thereby increasing the construction cost, and multi-level construction may also lead to extended construction period. In addition, due to the complexity of the structure, once the structure is damaged or needs maintenance, it may be necessary to remove multiple layers to reach the problem, which not only increases the difficulty of maintenance, but also may cause damage to other layers. The structure also has certain limitations. It is mainly aimed at the connection between the slope roof and the end wall. It may not be applicable to walls with parapets or other special structures or require additional design adjustments; for example, the presence of parapets may affect the arrangement and fixing methods of the flashing board and the additional waterproof layer.
[0005] In view of the shortcomings of the existing technology, this utility model patent proposes a new type of roof flashing waterproof protection structure, which aims to use a simple and easy to construct and load structure to solve the common quality problems in the existing construction methods, improve the bonding effect and durability of the waterproof layer, and at the same time optimize the appearance design of the roof parapet and exterior wall, improve space utilization efficiency, and has wide applicability.
