Description

Technical Field

[0001] This utility model relates to a waterproof structure, and more particularly to a combined box-type waterproof structure. Background Technology

[0002] Modular container units are enclosed or semi-enclosed box-shaped structures assembled on-site or at a designated location from multiple prefabricated components or modules using specific connection methods (such as bolts, welding, riveting, snap-fit, etc.). Existing connection methods include: Method 1: Mechanical connection, corner lock connection: using standard container corner fittings to install locking rods or rotary lock heads, and achieving mechanical locking between containers through bolt tightening; and Pin-type connectors: pre-embedded slots on the container edges, inserting metal pins for fixation. Advantages: quick installation, suitable for temporary splicing, no welding required, and... The first method involves minimal damage to the enclosure, but its disadvantages include poor sealing, gaps between the connectors and the enclosure, reliance on simple rubber gaskets which are prone to aging and water leakage, low structural strength, weak resistance to earthquakes and shear forces, and a tendency to loosen over long-term use. The second method involves welding connections: intermittent welding (partially welding steel plates or angle steel along the joint edges of the enclosure); and continuous welding (fully welding metal plates along the joints to form an integral structure). Advantages include high connection strength, good stability, and a reduction in joints to some extent. Disadvantages include reliance on adhesives for waterproofing, requiring the application of sealant after welding, and the adhesive's susceptibility to UV aging.

[0003] Method 3 is a hybrid connection of mechanical and welding. The box is temporarily fixed with bolts first, and then the key stress points are welded. A welded steel frame is installed inside the box and connected to the outside with bolts. Advantages: It takes into account both installation speed and some strength requirements. Disadvantages: Sealing problems still exist; the process is complicated and the cost is high. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology by providing a modular waterproof box structure, which solves the problems of poor sealing and low structural strength of modular boxes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a combined waterproof box structure, comprising two spliced ​​boxes and a joint between the two spliced ​​boxes. A waterproof mechanism is provided at the joint between the two spliced ​​boxes. The waterproof mechanism includes a sealing strip disposed within the joint, structural adhesive disposed within the joint and located outside the sealing strip, and a metal cover plate covering the structural adhesive. The metal cover plate includes a pair of L-shaped angle steels disposed on both sides of the joint and a waterproof cover plate fastened and welded to the pair of L-shaped angle steels. The waterproof cover plate has a C-shaped cross-section. One right-angle side of the L-shaped angle steel is welded to the spliced ​​box, and the other right-angle side is close to the joint. The two L-shaped angle steels are arranged in a mirror symmetrical manner, and the other right-angle sides face each other. The waterproof cover plate is fastened and welded to the corresponding right-angle side of the L-shaped angle steel, and the other right-angle side is disposed inside the waterproof cover plate. The two L-shaped angle steels and the waterproof cover plate form a sealing groove space, and the joint is disposed within the sealing groove space.

[0006] Furthermore, the sealing strip is a T-shaped sealing strip.

[0007] Furthermore, the structural adhesive is a weather-resistant structural adhesive.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] To address the need for waterproofing modular enclosures, the designer of this utility model has innovatively proposed a waterproof structure for modular enclosures. This structure can improve the airtightness and shear resistance of the modular enclosures, resulting in high structural strength, simple structure, low cost, and an improved waterproof rating of IP67.

[0019] like Figures 1 to 3 As shown, a modular waterproof box structure includes two assembled boxes 1 and a joint 2 between the two assembled boxes 1. A waterproof mechanism 3 is provided at the joint 2 between the two assembled boxes 1. The waterproof mechanism 3 includes a sealing strip 4 disposed within the joint 2, structural adhesive 5 disposed within the joint 2 outside the sealing strip 4, and a metal cover plate covering the structural adhesive 5. The metal cover plate includes a pair of L-shaped angle steels 6 disposed on both sides of the joint 2 and waterproof cover plates 7 fastened and welded to the pair of L-shaped angle steels 6. The waterproof cover plate 7... The cross-section is C-shaped. One right-angled side of the L-shaped angle steel 6 is welded to the splicing box 1, and the other right-angled side is close to the joint 2. The two L-shaped angle steels 6 are arranged in a mirror symmetrical manner, and the other right-angled sides face each other. The waterproof cover plate 7 is fixed to the corresponding right-angled side of the L-shaped angle steel 6 by intermittent welding, and the other right-angled side is set inside the waterproof cover plate 7, which not only blocks ultraviolet rays but also enhances the lateral force. The two L-shaped angle steels 6 and the waterproof cover plate 7 form a sealing groove space 8. The joint 2 is set in the sealing groove space 8 to block the heat conduction path.

[0020] The sealing strip 4 is a T-shaped sealing strip 4, and the T-shaped sealing strip 4 is made of EPDM material.

[0021] The structural adhesive 5 is a weather-resistant structural adhesive.

[0023] The waterproof cover plate 7 has a heat insulation pad on its inner wall. The heat insulation pad is a rubber pad. The waterproof cover plate 7 is a bent C-shaped 304 stainless steel plate with a thickness of 1.2mm and a 3mm rubber pad inside.

[0024] The outer surface of the metal cover plate is coated with an epoxy zinc-rich primer for corrosion protection.

[0025] During installation, the container is hoisted so that the flanges of the angle steel on both sides are aligned. A T-shaped sealing strip 4 is placed in the joint 2 between the two spliced ​​containers 1 and compressed to a deformation rate of 30% to 50%. Weather-resistant structural adhesive 5 is injected into the joint 2 and, after curing, forms a continuous adhesive layer with a thickness of ≥3mm. A whole L-shaped angle steel 6 is fully welded at the joint 2 of the two containers to form a continuous rigid support frame. The waterproof cover plate 7 is fastened to the outside of the angle steel on both sides and spot-welded every 200mm along the edge of the waterproof cover plate 7. Finally, the joint is fully welded to seal it. The L-shaped angle steel 6 and the waterproof cover plate 7 form a "reinforcing rib" between the spliced ​​containers 1, increasing the shear resistance to more than twice that of traditional connections.

[0026] The beneficial effects of the above-mentioned structure are as follows: The combined waterproof box structure provided by this utility model achieves double-layer long-lasting sealing by means of physical compression and chemical bonding of the sealing strip and structural adhesive, and the addition of a metal cover plate on the outside enhances the airtightness of the combined box and improves the waterproof rating. At the same time, the L-shaped angle steel of the metal cover plate and the waterproof cover plate form a reinforcing rib between the boxes, which improves the shear resistance of the combined box.
