Description

Technical Field

[0001] This utility model relates to a protective sleeve, specifically an irregularly shaped sleeve structure. Background Technology

[0002] With the increasing demand for various protective measures, traditional anti-corrosion paint for steel structures is no longer sufficient to meet the higher requirements of modern applications. While conventional square steel structures can be protected directly with end caps, trapezoidal steel structures with two folds on the trapezoidal side followed by a 90-degree outward fold, conventional protective covers are ineffective. Because the outward fold protrudes above the outer end face, the cover does not fit snugly against the end face, resulting in poor support. Under external stress, the structure is prone to deformation. Furthermore, this affects the strength of the zipper and adhesive bonding between the cover and the protective sleeve or tube surrounding the steel structure, thus compromising protective performance. Summary of the Invention

[0003] This utility model provides a special-shaped sleeve structure that effectively ensures the fit of the end face and the folded edge, providing safe and stable protection for the protection of trapezoidal cross-section structures with external folded edges.

[0004] The technical solution adopted by this utility model is: an irregularly shaped sleeve structure, characterized in that: it includes an end cover and a folded edge cover fitted onto the outer end face of a steel material with an outer folded edge. The end cover includes an end face and an edge covering. The end cover is a cover structure integrally cut from a whole outer protective material. Folded edge holes with outward flanges are cut inward from the outer folded edge side on the end face. The folded edge cover is a cover structure integrally cut from a whole outer protective material and corresponding to the outer folded edge. An outer bonding section extends outward from the three outer sides of the folded edge cover that do not correspond to the folded edge holes. The outer bonding section is bonded to the outer side of the three outer edge coverings via inner fasteners. The outer flange is bonded to the inner side of the folded edge cover via outer fasteners. The whole outer protective material includes a fiberglass cloth layer and a fireproof and heat-insulating layer. The upper and lower parts of the fireproof and heat-insulating layer are bonded and hot-pressed together with the fiberglass cloth layer.

[0005] The fireproof and heat-insulating layer is an aerogel layer, a rock wool layer, or a mineral wool layer.

[0006] A zipper is provided around the outer edge of the edging.

[0007] This utility model addresses the protection requirements of trapezoidal cross-section steel structures with external folded edges. It employs a combination of an end-face cover and a folded edge cover. The end face cover's end portion fits snugly against the end face, ensuring stable fit. The end face cover has folded edge holes corresponding to the external folded edge positions. The external folded edge passes through these holes, and the folded edge cover covers the 90-degree folded edge. The inner bottom and sides of the folded edge cover fit well against the two sides of the 90-degree folded edge, ensuring stable fit. Furthermore, the folded edge cover's three extended sides are bonded to the edge of the end face cover, with the inner side of the folded edge cover bonded to the external folded edge. This ensures a stable fit between the folded edge cover and the end face cover, and provides convenient disassembly, maintenance, and replacement. The end face cover and folded edge cover are made of a single sheet of fire-resistant and heat-insulating material, consisting of upper and lower fiberglass cloth layers, effectively balancing ease of structure forming and stable protective performance.

[0013] The following explanation, in conjunction with the accompanying drawings, will provide further details.

[0014] Figure 1-4 As shown: A non-circular sleeve structure, consisting of an end cover 3 and a folded edge cover 8 fitted onto the trapezoidal end face 1 of a steel material with an outer folded edge 2. The end cover 3 includes an end face 4 and a edging portion 7. The end cover is a cover structure integrally cut from a single piece of outer protective material. The end face 4 is cut inward from the outer folded edge side to form a folded edge hole 5 with an outer flange 6 and a through-hole for the outer folded edge 2. The folded edge cover 8 is a cover structure integrally cut from a single piece of outer protective material, corresponding to the outer folded edge. The three outer sides of the folded edge cover 8 that do not correspond to the folded edge hole have an outer bonding section 9 extending outward. The outer bonding section 9 is bonded to the outer side of the three outer edging portions 7 via an inner hook and loop fastener. The inner side of the folded edge cover 8 is bonded to the outer flange 6 via an outer hook and loop fastener. The entire outer protective material includes a fiberglass cloth layer 11 and a fireproof and heat-insulating layer 10. The upper and lower parts of the fireproof and heat-insulating layer are bonded and hot-pressed together with the fiberglass cloth layer.

[0015] In this embodiment, the fireproof and heat-insulating layer can be an aerogel layer, a rock wool layer, or a mineral wool layer.

[0016] Based on this embodiment, the protective tube or sleeve that is wrapped around the inner side of the steel structure end face is connected by a zipper on the outer edge of the edging.
