Mobile Toilet Floor Construction

The construction of mobile toilet floors requires selecting a plan based on the scenario. Common construction key points are as follows:

I. Construction Plan for Mobile Bathroom Floors

1. Material Selection

   • Surface Material: Use anti-slip ceramic tiles (size 600×600mm), which must meet an anti-slip coefficient of ≥0.6 (wet state), water absorption rate of ≤0.5%, and Mohs hardness of ≥6. Full-body antique tiles or wood-grain tiles are recommended, with a texture depth of 0.8-1.2mm.
   • Substrate Structure: The load-bearing substrate is a 3mm-thick aluminum alloy honeycomb composite panel (density ≥0.8g/cm³, compressive strength ≥15MPa). The support frame is made of 6061-T6 aluminum profiles (cross-section 40×20mm, wall thickness 1.5mm), and the adjustable feet are M10 stainless steel supports (adjustment range 30-80mm, load-bearing capacity ≥300kg each).
   • Waterproofing System: The substrate waterproofing uses a two-component polyurethane coating (dry film thickness ≥1.5mm, tensile strength ≥2.4MPa). Joint sealing is done with butyl rubber tape (width 50mm, peel strength ≥8N/cm). The drainage component is a 304 stainless steel linear drainage channel (width 50mm, slope 5‰).

2. Construction Preparation

   • Technical Preparation: Draw a layout plan, specifying panel divisions (≤1.8m×1.2m), drainage channel positioning (≥150mm from walls, 45° mitered corners at turns), and pipeline routing (avoiding support feet by ≥100mm). Measure the foundation flatness (2m straightedge error ≤5mm), temperature and humidity (5-35℃, humidity ≤75%), and load-bearing capacity (≥2.5kN/m²).
   • On-site Preparation: Clear ground protrusions (>3mm must be ground down), snap positioning axes (deviation ±2mm), and install a temporary drainage system. Soak tiles for 24 hours and air-dry them. Anodize the aluminum alloy substrate (film thickness ≥10μm) and age the waterproof coating for 15 minutes (stirring speed 600r/min).

3. Core Process

   • Substrate Treatment: Use self-leveling cement for leveling (thickness 5-10mm, flatness error ≤3mm/2m), and cure for ≥48 hours.
   • Waterproofing Construction: Apply the polyurethane coating in three coats (primer 0.4kg/m², intermediate coat 0.6kg/m² + fiberglass cloth, topcoat 0.5kg/m²). After drying, conduct a 48-hour water immersion test.

II. Installation Guidelines for Mobile Toilets at the Sanmenxia Construction Site

1. Foundation Construction: Pour a 15cm-thick concrete cushion, reserving a drainage slope of ≥2%. Harden the ground with anti-slip tiles.
2. Installation Steps: Hoist the cabinet and check its levelness (error ≤3mm), and secure adjacent units. Install sinks, flushing systems, and lighting fixtures, connect to a Φ20mm galvanized pipe water source, and test drainage smoothness.

III. General Construction Key Points for Mobile Restrooms

1. Clear the ground at the construction site to ensure it is free of debris.
2. Erect a sturdy support frame (made of wood or metal materials) and adjust its height according to the design.
3. Lay anti-slip, easy-to-clean floor materials (such as anti-slip tiles or PVC flooring), paying attention to joint sealing treatment.
