AI Technical Summary

Technical Problem

Existing building eaves designs fail to effectively prevent rainwater from leaking back into the joints between canopy materials, leading to staining and puddle formation.

Method used

The design incorporates a notch in at least a portion of the canopy material at the joint with an adjacent canopy material, allowing rainwater that enters between the materials to be drained, preventing it from flowing back and causing leaks or puddles.

Benefits of technology

The notch configuration effectively drains rainwater, suppressing staining and puddle formation by redirecting water away from unintended areas, ensuring a watertight and aesthetically pleasing structure.

Abstract

To provide a building eaves capable of suppressing stains caused by unintended rain leakage and puddles even when rainwater flows back due to capillary action.SOLUTION: The building eaves includes a base frame 20 attached to the building structure and an eaves plate 11 supported by the base frame 20. The eaves plate 11 is formed by joining a plurality of eaves materials 12 in the width direction W, and at least a portion of the eaves materials 12 has a cutout portion 35 on the upper surface side of the joint with the adjacent eaves materials 12, and the joint has an engagement portion 61a that fits into and hooks onto the adjacent eaves materials 12, and the cutout portion 35 is formed at a position that includes at least a portion of the engagement portion 61a.SELECTED DRAWING: Figure 12
