Ventilation member and wall material construction structure

The ventilation member divides the ventilation layer into multiple segmented regions using partition plates. Multiple ventilation holes are distributed across different segments (upper, middle, lower regions), ensuring uniform air distribution and pressure balance throughout the entire ventilation layer, not just at the ends.

The invention transitions from a one-dimensional ventilation approach (only at upper and lower ends) to a two-dimensional distribution system. Ventilation holes are arranged in multiple rows and columns across the ventilation member surface, creating a grid-like pattern that provides ventilation across the entire width and height of the ventilation layer.

The ventilation member acts as an intermediary component between adjacent wall materials. It provides a robust joining structure with thick plates and multiple fastening points,弥补ing the weakness of thin shiplap portions while maintaining the ease of installation benefit.

The ventilation member is installed beforehand to provide structural support and water tightness before the thin wall materials are joined. The robust ventilation member structure compensates for the potential water tightness issues of thin shiplap portions in advance.

The ventilation member is divided into multiple segments with partition plates creating separate zones. Each segment has its own ventilation holes, allowing independent air flow control and pressure equalization across different height regions, preventing pressure differences in tall structures.

The invention adds a horizontal dimension to ventilation by distributing holes across the width of the ventilation member, not just vertically. This creates multiple air flow paths in both horizontal and vertical directions, ensuring uniform ventilation even in tall buildings.
