[0002] Polyurethane has a wide range of uses in various existing industries due to its excellent performance. Polyurethane boards have the advantages of light weight, low water absorption rate, good heat preservation effect, etc., and are commonly used in the construction of cold storages.
[0003] In most existing technologies, the lap joint method of polyurethane boards is to use male and female buckles or eccentric hooks and locking buckles for lap joint and fill sealant at the joints. However, in the case of very low temperatures in cold storages, since the sealant and polyurethane are not the same substance and there are different cold shrinkage ratios, there will be a technical problem that the seal between the boards is not tight, resulting in a reduction in heat preservation effect and energy waste. Therefore, we propose a polyurethane board structure. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment: Please refer toFigures 1-4 , the present utility model provides a technical solution: a polyurethane board structure, mainly aiming at the technical problem of poor sealing between boards in the splicing of polyurethane boards in the prior art, which causes the problems of reduced heat preservation effect and energy waste. The specific solution is as follows: It includes polyurethane board one 100 and polyurethane board two 200. Both polyurethane board one 100 and polyurethane board two 200 include upper panel 1 and lower panel 2. Among them, upper panel 1 and lower panel 2 are made of high-quality aluminized zinc color steel plates (aluminized zinc material), and high weather-resistant special coatings are selected on the surface. Through special coating processes, different colors are painted on the surface according to needs, and then pressed into different patterns by special metal embossing equipment, and then secondary coating is carried out to form a variety of color relief three-dimensional patterns. It can meet the appearance requirements of building shapes and colors, and achieve a certain fashion and artistic effect.
[0022] Furthermore, edge strip boards 150 are provided on upper panel 1 and lower panel 2. The cross-section of edge strip board 150 is "L" shaped. Among them, edge strip board 150 can protect the sides of upper panel 1 and lower panel 2 to avoid the occurrence of burrs.
[0023] Furthermore, a sandwich layer 3 is provided between upper panel 1 and lower panel 2. Among them, sandwich layer 3 uses flame-retardant treated rigid high-density environmentally friendly polyurethane foam insulation material. Insulation decorative boards with different foaming thicknesses can be selected in different regions. Both upper panel 1 and lower panel 2 are adhesively bonded to sandwich layer 3, and upper panel 1 and lower panel 2 are connected by connecting rods 5. Connecting rods 5 can increase the connection stability between upper panel 1 and lower panel 2, further prevent the loosening of upper panel 1 and lower panel 2, and ensure the use effect of the polyurethane board. It should be noted that, among them, connecting rods 5 can be welded between upper panel 1 and lower panel 2 after the adhesive bonding process of upper panel 1, sandwich layer 3 and lower panel 2 is completed.
[0024] Please refer to Figure 1 、 Figure 2 and Figure 3 , among which, polyurethane board one 100 and polyurethane board two 200 are fixedly installed through splicing assembly 4;
[0025] Specifically, splicing assembly 4 includes support plate 41 and clamping plate 45. A bearing plate 42 is fixedly installed on one side of support plate 41 corresponding to clamping plate 45. Bearing plate 42 is perpendicular to both support plate 41 and clamping plate 45, and bearing plate 42 is arranged between support plate 41 and clamping plate 45. Support plate 41 and clamping plate 45 are arranged oppositely, and support plate 41 and clamping plate 45 are parallel to each other. Both support plate 41 and clamping plate 45 are arranged between upper panel 1 and lower panel 2.
[0026] It should be noted that the side edges of the sandwich layer 3 are flush with the corresponding side edges of the upper panel 1 and the lower panel 2. Among them, the thickness of the edge strip board 150 is equal to the thicknesses of the support board 41 and the clamping board 45, so that after the splicing and installation are completed, the support board 41 and the clamping board 45 can be clamped between the upper and lower edge strip boards 150 and are flush with the corresponding side edge strip boards 150, making it easier to splice the polyurethane boards in all directions.
[0027] Among them, a flexible cushion 43 is arranged outside the bearing board 42. The bearing board 42 can support the flexible cushion 43. A square groove for inserting the bearing board 42 is arranged in the middle of the flexible cushion 43. The flexible cushion 43 is arranged between the upper panel 1 and the lower panel 2, and the thicknesses of the flexible cushion 43, the upper panel 1 and the lower panel 2 are equal. Among them, the material of the flexible cushion 43 is a kind of material of plastic foam (such as diene-based foams, hydrocarbon-based foam elastomers, and nitrile rubber foams, etc.). While ensuring the use effect of the polyurethane board, it is also convenient for the splicing operation of the polyurethane board one 100 and the polyurethane board two 200.
[0028] Furthermore, a clamping groove 44 for inserting the bearing board 42 is formed in the clamping board 45. The clamping groove 44 is a blind groove and is arranged in the middle of the bearing board 42. The upper and lower ends of the connecting rod 5 are movably inserted with connecting bolts 6, and threaded holes for inserting the connecting bolts 6 are formed in the support board 41. And the edge strip board 150 and the connecting rod 5 are fixedly installed. Clamping the bearing board 42 with the clamping board 45 can facilitate the replacement and installation of the flexible cushion 43, is easy to disassemble, and further ensures the splicing effect of the polyurethane board.
[0029] Working principle: For this polyurethane board structure, when splicing, first, the flexible cushion 43 is sleeved outside the bearing board 42; second, the bearing board 42 sleeved with the flexible cushion 43 is arranged between the polyurethane board one 100 and the polyurethane board two 200. At this time, the flexible cushion 43 is attached to the corresponding side of the polyurethane board one 100 and the polyurethane board two 200; finally, the clamping board 45 is clamped on the side of the bearing board 42 away from the support board 41, the connecting bolt 6 is passed through the connecting rod 5, and it is threadedly connected to the corresponding support board 41 and clamping board 45. By continuously tightening the connecting bolt 6, the polyurethane board one 100 and the polyurethane board two 200 can be made to approach each other, making the attachment of the polyurethane board one 100 and the polyurethane board two 200 more stable.
