A pre-installed dry toilet structure

Abstract

This invention relates to a prefabricated dry toilet structure, characterized by comprising wall panel modules, a roof panel module, an isolation door, and ventilation and waterproofing modules. By employing a frame-type wall panel structure, dividing the wall panel structure into inner core panels and outer outer panels, this modular construction structure greatly improves production efficiency, enabling factory production and on-site installation, thus increasing installation efficiency. The inner core panel uses concrete encasing a layer of foam particles, reducing its weight. The open and transparent roof panel module creates large ventilation openings and excellent ventilation performance. Furthermore, the rainproof panels and rainproof channels on the roof panel module effectively block rainwater, preventing it from entering the dry toilet. Isolation net units covering the frame beams prevent airborne debris from falling into the dry toilet, ensuring its cleanliness. The fasteners used eliminate the need for self-tapping screws or blind rivets to fix the isolation net units, reducing labor costs, simplifying the installation process, and improving installation efficiency.
