Description

Exterior Panel Gutter Drainage System The present invention relates to a system for installing exterior panels of a building, and more specifically, to a gutter drain system for exterior panels that provides an enhanced waterproofing effect by guiding moisture entering through the joints between exterior panels into a drain channel for efficient drainage, and facilitates convenient installation and maintenance through an elastic channel fitting structure. The exterior walls of modern buildings are required not only to provide aesthetics and thermal and sound insulation performance, but also to effectively prevent the penetration of rainwater or external moisture. To this end, curtain walls or various types of exterior panels are installed on the exterior walls, and these exterior panels are supported and installed by bracket members arranged in horizontal and vertical directions. Exterior panels arranged and installed in this manner are spaced apart from adjacent panels at regular intervals to cope with deformation caused by external environmental factors such as thermal expansion; consequently, horizontal and vertical joints are formed between the arranged exterior panels, and these joints become a major pathway for the inflow of moisture, such as rainwater. Accordingly, conventionally, a method of completely sealing the joint by filling it with a waterproofing material, such as a sealant, to prevent moisture from penetrating the joint has been widely used. However, there was a critical problem where the sealant (silicone) used to seal the joints would peel off or run down the exterior panels due to external environmental factors such as ultraviolet rays or solar heat after a certain period of time following construction, damaging the building's appearance and degrading waterproofing performance; additionally, there was the disadvantage of requiring periodic repair work for maintenance. To address these issues, technologies have been proposed that do not use any filler in the joints and allow the joints between exterior panels to remain open, while providing a drainage structure within the bracket device itself that supports the exterior panels. However, most conventional drainage structures have limitations in efficiently blocking and draining moisture in both horizontal and vertical directions. Furthermore, there is a problem in that moisture is not properly discharged at the joint intersections, allowing it to seep into the connections of bracket devices or the interior of panels, potentially causing leakage defects and structural corrosion. In addition, depending on the drainage structure, the configuration of the bracket device becomes complex, which leads to increased manufacturing costs and presents problems such as inconvenient and difficult on-site installation and maintenance. In addition, when joint spacing changes or manufacturing errors occur due to thermal expansion or structural deformation, it is difficult to respond flexibly to these issues. Consequently, the connections or joints of the drainage components may lift or develop gaps, leading to a problem where the waterproofing function cannot be properly performed. Meanwhile, the matters described in this background technology section are prepared to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs.
