Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of prefabricated cabins, and in particular relates to a spliced waterproof roof structure for a large prefabricated cabin. Background Art
[0002] When designing and producing herringbone waterproof roofs for large prefabricated cabins and box-type substations, the current standard approach is to splice panels together, either fully or partially welded, based on the size of the panels, then seal them with waterproof adhesive. A roof frame is then added below the welded seams for support. This method requires extensive welding work, and the welds must be polished to create a smooth surface. This reduces production efficiency for large waterproof roofs, and the seams are prone to rust over time.
[0003] Most existing waterproof roof covers adopt an integrated molding structure, which results in a large roof cover size, complicated installation and use, and poor convenience. At the same time, the existing modular assembled waterproof roof covers have poor waterproofing effect. Water will flow into the internal equipment through the gaps in the waterproof roof covers, causing damage to the corresponding equipment. The existing modular assembled waterproof roof covers are connected by welding, but welding is a non-detachable fixed connection. After welding and fixing, the cost of reuse is high and disassembly is difficult. At the same time, the existing waterproof structure is prone to water accumulation. Long-term water accumulation can easily lead to corrosion and damage of the waterproof structure, affecting the equipment to be protected inside. Utility Model Content

The side top cover group 1 and the intermediate top cover group 2 are provided with a first waterproof structure 3 and a second waterproof structure 4, and the first waterproof structure 3 and the second waterproof structure 4 are perpendicular to each other.
[0023] like Figure 2As shown, the cross-section of the first side top cover 11 is a trapezoidal structure, and the top of the first side top cover 11 is bent outward to form a first folded edge 5 of the first side top cover and a second folded edge 6 of the first side top cover respectively.
