Diagram Explanation of Outdoor Mobile Toilet Frame
The frame design of outdoor mobile toilets primarily uses steel structures, enabling rapid deployment and mobility through modular assembly. The core structural logic is as follows:

1. Main Frame Structure: Modular Steel Skeleton
The frame of outdoor mobile toilets employs steel welding techniques to form a modular skeleton that can be hoisted. The base is typically formed by welding channel steel or I-beams horizontally and vertically, creating a load-bearing foundation that ensures overall stability. Vertical columns are connected using square steel to form the wall support structure. For example, a base design with angle iron frames (L4*L4 angle iron with intermediate clamping plates) reduces weight while providing a flat installation surface through the clamping plates. Floor adhesive is applied on the surface to achieve anti-slip and moisture-proof functions.
2. Walls and Materials: Lightweight and Durable Combinations
Wall materials are selected based on the usage scenario, with common types including:
- Color-coated steel plates: Lightweight and with excellent thermal insulation, suitable for cold regions;
- Stainless steel: Highly corrosion-resistant, ideal for humid or coastal environments;
- Metal embossed plates: Combining aesthetics with durability, often used in high-end scenarios. These materials are fixed to the frame using bolts or welding to ensure structural stability. Some designs incorporate open hand-washing areas or ridge-shaped roofs to enhance functionality and adaptability.
3. Modular Design: Factory Prefabrication and On-site Assembly
The frame supports modular production, with walls, bases, and internal facilities (such as sanitary ware and water tanks) prefabricated in the factory. On-site, only water and electricity connections are required for immediate use. For example, the roof can integrate ventilation modules or lighting modules, and the base can have reserved sewage discharge ports, simplifying the installation process. Modular design also facilitates later maintenance and upgrades, reducing operational costs.
4. Mobility and Hoisting: Adapting to Various Transportation Methods
The frame structure must meet hoisting requirements, with common designs including:
- Top lifting rings: For overall handling by cranes;
- Forklift slots: For easy loading and unloading by forklifts;
- Wheeled chassis: Powered or towed mobile toilets are equipped with wheels for autonomous movement. Hoisting-type toilets rely on external equipment for transportation, while towed-type toilets require a tractor for cooperation, suitable for different scenario requirements.
Supplementary Diagram Logic:
- Base frame: Channel steel/I-beams form a grid-like load-bearing layer;
- Columns and beams: Square steel is vertically connected to form a three-dimensional support;
- Wall installation: Color-coated steel plates or stainless steel plates are fixed with rivets;
- Roof structure: Light steel keels + waterproof panels, integrating functional modules.
For specific drawings or technical parameters, it is recommended to contact the manufacturer (such as Dezhou Hongtu Metal Products Co., Ltd.) for detailed documentation.
