Fixed Bracket for Outdoor Mobile Toilet
The design of the fixed bracket for outdoor mobile toilets primarily relies on the steel structure framework within the modular structure. Although there is no explicitly named independent 'fixed bracket' component mentioned, its fixing principles and characteristics can be analyzed through its main supporting structure.
Steel Structure Framework as the Core Support
The fixing function of outdoor mobile toilets mainly depends on the steel structure framework, with the angle iron frame base being a typical design. For example, an L4*L4 angle iron (an equilateral angle steel with a side length of 40mm) is used to construct the base frame. This material has high bending and torsional strength, capable of bearing the overall weight of the toilet and external loads (such as wind forces and impacts from human activities). The design of the intermediate clamping plate in the angle iron frame further optimizes the structural performance: the clamping plate, usually made of steel plate or high-strength composite plate, serves two purposes. Firstly, it enhances the overall rigidity of the base by welding or bolting with the angle iron, preventing local deformation. Secondly, it provides a flat installation surface, facilitating the quick positioning and fixing of the main toilet body (such as the tank and sewage system).
Realization Principles of Fixing Methods
Although there is no explicit independent naming of a 'fixed bracket', the steel structure framework achieves the fixing function through the following methods:
- Foundation Anchoring: The base angle iron frame can be pre-drilled with anchor bolt holes, allowing the toilet to be fixed to a concrete foundation or ground using expansion bolts or chemical anchors, preventing horizontal displacement.
- Structural Self-Weight Stability: The combined design of the angle iron frame and clamping plate ensures strength while reducing the overall weight (compared to solid steel beams). However, by reasonably distributing the mass (such as concentrating heavy-duty components like water tanks and sewage tanks in the middle of the base), it can still achieve basic stability using its self-weight.
- Modular Connection: If the mobile toilet is a multi-module combined type, the angle iron frames of the steel structure framework can achieve rigid connections between modules using bolts or pins, indirectly enhancing overall stability.
Design Advantages and Limitations
Advantages: The modular design of the steel structure framework facilitates transportation and on-site assembly. The combination of the angle iron frame and clamping plate achieves a balance between strength, weight, and cost, making it suitable for complex outdoor environments.
Limitations: The reference information does not mention adjustable-height brackets or special fixing designs for soft soil foundations (such as deep foundations or expandable ground anchors). In extreme geological conditions, additional reinforcement measures may be required.
