Dimensions of Square Tube Frames for Mobile Toilets
The dimensions of square tube frames for mobile toilets vary depending on the specific type and design requirements, with common specifications as follows:
The frame structure of a mobile toilet typically consists of a bottom main frame, a bottom auxiliary frame, frame columns, and a roof frame, among other parts. Each part has different square tube dimensions due to varying load-bearing requirements and functional positioning.
The bottom main frame is the load-bearing core of the entire structure, needing to withstand the overall weight of the toilet and dynamic loads during use. Therefore, larger-sized square tubes are commonly used. Common dimensions are 80mm×80mm×3.2mm or 100mm×100mm×3mm hot-dip galvanized square steel tubes. Among them, the 80mm×80mm specification is suitable for small to medium-sized mobile toilets, while the 100mm×100mm specification is mostly used for large toilets or those that need to carry heavier equipment. The wall thicknesses of 3.2mm or 3mm ensure structural strength, and the hot-dip galvanizing process enhances rust resistance and extends service life.
The bottom auxiliary frame is mainly used to support the bottom panel or connect to the main frame, with relatively lower load-bearing requirements, so its dimensions are smaller. A common specification is 80mm×40mm×2.5mm square steel tubes. This dimension can meet auxiliary support needs while controlling material costs. The 2.5mm wall thickness ensures structural stability and facilitates processing and installation.
The frame columns are key components connecting the bottom and the roof, needing to withstand vertical loads and lateral wind forces. Dimension selection should balance strength and stability. Common specifications include 40mm×40mm×1.5mm and 80mm×80mm galvanized square tubes. The 40mm×40mm specification is suitable for light or small toilets, with a 1.5mm wall thickness meeting basic load-bearing requirements. The 80mm×80mm specification is mostly used for large toilets or those requiring higher wind resistance, with its larger cross-sectional dimension significantly enhancing structural rigidity.
The roof frame needs to withstand loads such as rainwater and snow accumulation while connecting with the walls to form an integral structure. Therefore, medium-sized square tubes are commonly used. Common dimensions are 40mm×60mm×1.8mm or 40mm×80mm×2mm galvanized square tubes. The 40mm×60mm specification is suitable for ordinary roof designs, with a 1.8mm wall thickness meeting regular load requirements. The 40mm×80mm specification is mostly used for designs with larger spans or those needing to increase roof strength, with a 2mm wall thickness further enhancing structural safety.
