Mobile Toilet Base Plate Production

The production of mobile toilet base plates requires selecting structures and materials based on specific design requirements. Common solutions include double-layer metal frame structures or steel keel composite structures, which must balance load-bearing capacity, slip resistance, corrosion resistance, and drainage functionality.

I. Key Points for Double-Layer Metal Frame Structure Production

This type of base plate primarily uses metal materials, with an aluminum plate as the top layer and a welded galvanized pipe frame as the bottom layer. The aluminum plate, as the surface material, is lightweight, corrosion-resistant, and easy to clean. Its surface can be treated for slip resistance (e.g., embossing or applying a non-slip coating), with a typical thickness of 2-3mm. The welded galvanized pipe frame at the bottom serves as the core load-bearing structure. The frame spacing should be designed according to the toilet size (generally 30-50cm apart). It is recommended to use galvanized steel pipes with a diameter of 40-60mm. During welding, ensure smooth welds without cold welds to prevent deformation after long-term use. Adjustable feet can be installed at the bottom of the frame to accommodate different ground slopes. During production, note that the aluminum plate and frame should be fixed with rivets or bolts at intervals not exceeding 20cm. If used for dry toilets, reserve space inside the frame for installing a waste collection tank and ensure tight sealing.

II. Key Points for Steel Keel Composite Structure Production

This structure uses a steel keel with solid wood or cement board at the bottom, a non-slip material on the surface, and reserved drainage space at the bottom. The steel keel, as the main support, should be welded into a grid pattern using 50×50mm square tubes, with spacing controlled within 40cm. After welding, apply anti-rust treatment (e.g., spraying epoxy zinc-rich paint). The solid wood or cement board serves as the base layer. For solid wood, use anti-corrosion-treated pine or fir with a thickness of ≥15mm. For cement boards, it is recommended to use 12mm-thick high-density fiber cement boards, which should be pre-cut to match the size of the steel keel and fixed with self-tapping screws. The surface material should be selected based on the usage scenario: non-slip quartz tiles are highly wear-resistant but require expansion joints; patterned aluminum plates are lightweight and rust-resistant, suitable for humid environments; non-slip PVC is low-cost but requires regular replacement. Reserve ≥20cm of space at the bottom for installing a waste collection tank or connecting to drainage pipes. It is recommended to use a PE waste collection tank with a capacity designed according to usage frequency (generally 50-100L) and equipped with a sealed lid to prevent odor diffusion.

III. Key Processes and Precautions

Regardless of the structure used, waterproofing is a critical step: metal components should be sprayed with anti-rust paint, wooden base layers should be coated with waterproof paint, and seams should be sealed with glass glue. Load-bearing testing cannot be overlooked. After production, simulate adult standing (at a standard of 150kg/㎡) for pressure testing to ensure no deformation or abnormal noises occur. Drainage design should be adjusted according to the toilet type: for dry toilets, tilt the base plate (with a slope of ≥2%) to guide waste into the collection tank; for flush toilets, reserve a drainage slope (≥1%) and install a floor drain with a diameter of ≥50mm to prevent clogging.
