Description

Technical Field

[0001] The utility model relates to the technical field of flashing edge trimming nodes, in particular to a flashing edge trimming node structure. Background Art

[0002] Flashing is an important node of the external protection structure. Flashing is generally done by directly overlapping the corrugated board from the external protection to the parapet. In this project, since the external protection wall board is more than 400mm away from the parapet, and the maximum spacing is 1000mm, if only a single-layer corrugated board is overlapped to the parapet, the overlap position of the corrugated board will collapse after a long time due to the insufficient strength and lack of support of the single-layer corrugated board. When it rains, rainwater will leak into the indoor space through the weak overlap position, which will have a great impact on the use of the indoor space in the future. Therefore, the flashing node structure is proposed. Utility Model Content

[0005] Preferably, the first galvanized angle steel, the galvanized square tube and the thick galvanized folding piece are fixedly installed by self-tapping screws, and the second galvanized angle steel and the outer wall panel are fixedly installed by expansion bolts. Here, the self-tapping screws can provide a stable and reliable fixing effect, enhancing the stability of the entire structure, and the expansion bolts can ensure that the connection between the outer wall panel and the second galvanized angle steel is more stable, increasing the safety and durability of the overall structure.

[0006] Preferably, the length of the galvanized square tube is set according to the distance between the parapet body and the outer wallboard, and the galvanized square tube is set with a certain slope. Here, it is helpful to achieve accurate matching of the structure and natural drainage, taking into account the variability and water flow requirements in practical applications, and increasing the adaptability and functionality of the node structure.

[0007] Preferably, the flashing edge trimming member and the parapet body are sealed with a polyurethane foam plug, and the connection between the flashing edge trimming member and the parapet body and the parapet cover plate is filled with a waterproof sealant for a second time. Here, the sealing performance at the node is enhanced, water penetration is effectively prevented, the interior of the structure is protected from water damage, and a chemical waterproof barrier is formed, thereby greatly improving the waterproof performance and durability of the entire structure.

[0008] Preferably, the parapet wall cover plate and the thick galvanized folding member are fixedly connected by self-tapping screws. Here, the integrity and wind pressure resistance of the entire node structure are enhanced, and future maintenance or replacement work is also facilitated.
