[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The 26,000-ton self-unloading ship is equipped with desulfurized washing water inside the washing circulation cabin, so the conventional method of setting fireproof insulation material 2 inside the cabin is not applicable. First, if it is set inside the washing circulation cabin, the washing liquid inside it will easily enter the insulation material 2 during long-term use and affect the effect; secondly, the manhole of the washing circulation cabin is small, which is not convenient for the entry of construction materials. If it is divided into smaller materials, it will inevitably increase the construction difficulty and period. In order to meet the insulation requirements of the cabin, insulation material 2 must be set on the outside.

[0032] Embodiment 1:

[0033] The present invention provides a structure for outdoor installation and heat insulation, comprising a cabin wall 1, a heat insulation material 2, and a frame 3, wherein the frame 3 is arranged on the outer side of the cabin wall 1, such as Figure 1 , 2As shown, the present invention arranges the heat insulating material 2 on the outside of the cabin enclosure 1, thereby making up for the disadvantage that the heat insulating material 2 cannot be arranged in the washing cycle cabin. The cabin enclosure 1 includes the vertical facades and the horizontal deck around the cabin. The present invention can be arranged on the outer facades or the horizontal deck surfaces of the cabin enclosure 1. In order to ensure that the horizontal deck surface still has a good bearing effect after installation on the horizontal deck surface, the interior of the enclosure 3 is designed to be a well-shaped filling grid 4. The filling grid 4 formed at the boundary of the enclosure 3 and the interior of the enclosure 3 are made of angle steel, thereby forming a frame structure. The specification of the angle steel is L50*50*5, and then the outer cover plate 5 is covered on the outer side of the filling grid 4 distributed in the well shape. The filling grid 4 can form a good supporting effect on the cover plate. In actual use, a filling grid 4 with a slightly larger density can be arranged on the horizontal deck surface as needed, and the density of the filling grid 4 can be appropriately reduced on the vertical facade.

[0034] like Figure 3 As shown, each filling cell 4 is filled with heat-insulating material 2, so that the outer cover plate 5 forms a supporting panel on the outside, and the heat-insulating material 2 filled on the inner side of the filling cell 4 plays a major role in heat insulation. Since the heat-insulating material 2 is arranged on the outer surface of the cabin, the structural arrangement inside the washing circulation cabin will not be changed. The outer cover plate 5 covers the outside of the filling cell 4, and the outer cover plate 5 is sealed and connected to the filling cell 4 to seal the heat-insulating material inside the filling cell 4.

[0035] The thermal insulation material 2 adopts a multi-layer composite board structure, each layer includes a reflective layer 6, a heat insulation layer 7, and a flame retardant layer 8. The flame retardant layer 8 is provided with heat insulation layers 7 on both sides, and the outer sides of the heat insulation layers 7 on both sides are provided with reflective layers 6. The flame retardant layer 8 is a flame retardant polypropylene board or a glass magnesium fireproof board, which has high temperature resistance, flame retardancy, sound absorption and shockproof functions, and the fire resistance level reaches A1 level; the heat insulation layer 7 is a rock wool board or a ceramic wool board, and the reflective layer 6 is an aluminum film layer. The flame retardant layer 8, the heat insulation layer 7, and the reflective layer 6 are connected by adhesive to form an integrated thermal insulation material 2, and the thickness of the thermal insulation material 2 is not less than 50 mm.

[0036] like Figure 3 As shown, in order to facilitate the quick and easy pre-fixation of the thermal insulation material 2 during construction, studs 9 can be used. During installation, the studs 9 are passed through the thermal insulation material 2 to form a quick fixation, which is convenient for the subsequent covering and welding operations of the outer cover 5. A plurality of studs 9 can be evenly distributed in each filling grid 4 to fix the thermal insulation material 2 from multiple positions. The studs 9 pass through the thermal insulation material 2 and are welded to the cabin wall 1.

[0037] When welding the outer cover plate 5, Figure 1As shown, the outer cover plate 5 is provided with a plug welding hole 10 at a position corresponding to the surrounding frame 3, and the outer cover plate 5 and the surrounding frame 3 are welded and fixed through the plug welding hole 10. The thickness of the outer cover plate 5 is not less than 5 mm, the plug welding holes 10 are arranged at intervals of 100 mm, and the plug welding holes 10 have a diameter of 10 mm.

[0038] The present invention provides a construction method for installing a heat insulation structure outdoors, comprising the following steps:

[0039] S1: Installation of the enclosure 3, vertically welding one side of the angle steel to the vertical elevation of the cabin enclosure 1 or the horizontal deck plane, the angle steels are staggered and arranged in a tic-tac-toe pattern in the horizontal and vertical directions, and the horizontal and vertical angle steels enclose a plurality of filling grids 4;

[0040] S2: Stud installation, one end of the stud 9 is welded to the outside of the cabin wall 1, and the other end extends out of the insulation material 2 or is provided with a thread on the extended section. The insulation material 2 is cut into a rectangular shape adapted to the area of ​​each filling grid 4, and a through hole for the stud 9 to pass through is reserved on the rectangular insulation material 2;

[0041] S3: Laying the heat insulation material 2, filling each filling grid 4 with the cut heat insulation material 2, and after the heat insulation material 2 is laid, buckling the stud cap with a blind hole on one side onto the extended section of the stud 9, or threading the stud cap with a screw hole on the other end to the end of the extended section with a thread;

[0042] S4: The outer cover plate 5 is made of a 5 mm thick steel plate, the steel plate is cut to match the boundary of the surrounding frame 3, and a plug welding hole 10 with a diameter of 10 mm is opened every 100 mm at the corresponding position where the outer cover plate 5 is attached to the filling grid 4 of the surrounding frame 3;

[0043] S5: Cover the steel outer cover plate 5 on the angle steel enclosure frame 3, and fix the outer cover plate 5 and the angle steel enclosure frame 3 by welding through the plug welding holes 10. After the plug welding is completed, the outer cover plate 5 is polished and smoothed, and the boundary of the enclosure frame 3 and the outer cover plate 5 are fully welded;

[0044] S6: After welding is completed, repaint.

[0045] Based on the “Installation measures for outdoor insulation of open-air enclosures / decks”, scheme design and on-site construction were carried out, and the outdoor insulation installation was successfully completed at the open-air enclosure / deck position of the washing circulation tank of the 26,000-ton self-unloading ship. This not only met the shipowner's desire to alleviate the impact of low temperature on the washing water in the washing circulation tank through covering insulation, but also created a precedent for the outdoor installation of insulation materials in the open air, and provided design ideas and installation measures for similar situations in the future, which is of great reference significance.
