A gutter device for a roof deformation joint

Abstract

This utility model provides a drainage ditch device for roof expansion joints, belonging to the technical field of drainage ditch devices. It includes a concrete structure with two symmetrically arranged drainage ditch bodies on the top, each with an outer drainage ditch on its outer wall. In use, the opposing drainage interfaces of the two drainage ditch bodies drain surrounding surface water, while rubber pads reduce seepage. The serrated blocks at the bottom of the rubber pads and the serrated grooves at the top of the drainage ditch bodies are connected by an interlocking mechanism, increasing sealing and reducing seepage. The opposing drainage interfaces of the two drainage ditch bodies drain a small amount of seepage, while the aluminum plate prevents even a tiny amount of seepage water that has passed through the rubber pads from flowing into the interior through the expansion joint. This eliminates protrusions at the expansion joint, allowing people to enter and exit without having to climb several steps, improving the visual appeal of the roof and reducing the risk of seepage.
