As shown in fig. 1-4, the refrigeration storage plate-to-seam joint system of the present application includes a refrigeration storage plate 1, a two-component polyurethane thermal insulator 3, and a cover plate 4. The thickness of the refrigeration house plate 1 can be 240mm, a butt joint 2 is arranged between two adjacent refrigeration house plates 1, the width of the butt joint 2 can be 30mm, the double-component polyurethane heat preservation body 3 is filled in the butt joint 2, the cover plate 4 is fixed on the inner side (located on one side of a warm area) and the outer side (located on one side of a cold area) of the refrigeration house plate 1, and the double-component polyurethane heat preservation body 3 is shielded. The double-component polyurethane heat insulator 3 can ensure the continuity of the whole body, thereby ensuring the heat insulation continuity and the sealing performance to the seam 2.
The two-component polyurethane thermal insulator 3 is formed by foaming black and white materials in situ. Before foaming, the cover plate 4 positioned on the outer side of the refrigeration house plate 1 is fixed on the refrigeration house plate 1, and then the foaming machine is opposite to the butt joint seam 2 on the inner side of the refrigeration house plate 1 for foaming to form the two-component polyurethane heat insulation body 3. The double-component polyurethane heat insulator 3 foamed on site has good continuity and low possibility of generating bubbles, and ensures the continuity of heat insulation and the tightness of the joint 2; and the heat conductivity coefficient of the double-component polyurethane heat insulator 3 can reach 0.022, and the heat insulation effect is good. And after foaming is finished, fixing the cover plate 4 on the inner side of the refrigeration house plate 1.
The cover plates 4 located at the inner side and the outer side of the cold storage plate 1 may be sealed and adhered to the cold storage plate 1 by a sealant 5 (for example, butyl tape, the size of which may be 1.5 (width) × 20 (thickness)) and then fixed by pulling a rivet 10(Φ 5 × 13mm) to ensure the sealing property of the connection position. The cover plate portions on both sides of the butt seam 2 may be 50mm in length. The sealant 5 can be positioned on two sides of the two-component polyurethane heat-insulating body 3, namely the sealant 5 and the two-component polyurethane heat-insulating body 3 are positioned at different positions of the cover plate 4, and the sealant 5 is not bonded with the two-component polyurethane heat-insulating body 3, so that the sealant 5 can be conveniently arranged on the basis of ensuring the sealing property.
After installing apron 4 of 1 inboard in refrigeration house, can brush airtight glue 6 one earlier on the refrigeration house 1 of apron 4 both sides, then do non-woven fabrics 7, non-woven fabrics 7 lies in the apron 4 outside and bonds with airtight glue 6 on the refrigeration house 1, then brush airtight glue 6 one in the outside of non-woven fabrics 7. The density of the nonwoven fabric 7 may be 40g/m3. By the arrangement, the tight inlet and outlet of water vapor can be ensured, namely the water vapor can flow from the indoor to the outdoor and cannot enter the indoor from the outdoor, so that the sealing performance of the warm area is enhanced by adding the high-molecular airtight glue 6 and the non-woven fabric 7 at the position of the warm area, the water vapor is blocked from entering the cold area, the construction is rapid, and the labor and the time are saved; meanwhile, outdoor water vapor and indoor water vapor are mixed in the double-component polyurethane heat insulation body 3, the temperature consistency of all parts of the double-component polyurethane heat insulation body 3 is guaranteed, and the risk that the sealing performance, consistency and the like are influenced due to precooling and shrinkage of the double-component polyurethane heat insulation body 3 is reduced.
In addition, still be equipped with wall purlin 8 in the inboard of refrigeration house board 1, wall purlin 8 can be the steel purlin, fixes on refrigeration house board 1 through special nylon bolt, supports refrigeration house board 1, the increase in strength. The wall purlines 8 are positioned on two sides of the butt joint 2, so that a construction surface can be reserved at the position of the butt joint 2, so that construction is facilitated, and cold leakage is facilitated to overhaul.
And a heat-insulating sealing strip 9 can be arranged between the wall surface purline 8 and the refrigeration house plate 1. The heat-insulating sealing strip 9 can be a PU (Polyurethane) heat-insulating sealing strip 9 with the thickness of 2mm, so that the heat transfer efficiency from the wall purline 8 to the refrigeration house plate 1 is reduced, and the heat insulating property of the system is improved.
After each part is arranged, the inner side of each cold storage plate 1 is provided with a wall surface purline 8, airtight glue 6, sealant 5, butt joint seams 2, sealant 5, airtight glue 6 and a wall surface purline 8 which are not overlapped from one cold storage plate 1 to the other cold storage plate 1.
The sealing method of the cold storage plate 1 to the joint 2 node system comprises the following steps: an outer cover plate 4 is fixed on the outer side of each cold storage plate 1, and the outer cover plate 4 shields a butt joint seam 2 between every two adjacent cold storage plates 1; from the inner side of the refrigeration house plate 1, a foaming machine is opposite to the butt seam 2, and the two-component polyurethane of black and white materials is foamed on site to form a two-component polyurethane heat insulation body 3 filled in the butt seam 2; an inner cover plate 4 for shielding the butt seam 2 is fixed on the inner side of the refrigeration house plate 1. The double-component polyurethane heat insulator 3 foamed on site has good continuity and low possibility of generating bubbles, and ensures the continuity and the sealing property of heat insulation; the heat conductivity coefficient of the double-component polyurethane heat insulator 3 can reach 0.022, and the heat insulation effect is good; the operation is convenient and quick, and the construction is convenient.
The outer cover plate 4 and the inner cover plate 4 are sealed with the refrigeration house plate 1 by the sealant 5 and then fixed by the connecting piece (such as the rivet 10). After the inner cover plate 4 is fixed with the refrigeration house plate 1, airtight glue 6 is sequentially brushed on the refrigeration house plate 1 positioned at two sides of the inner cover plate 4, non-woven fabrics 7 are made on the outer side of the inner cover plate 4, and the airtight glue 6 is coated on the outer side of the non-woven fabrics 7. So set up, the leakproofness is good, blocks that steam gets into cold district, simple structure, convenient operation, it is laborsaving to save trouble.
