Compared with traditional civil cold storage, prefabricated cold storage has good thermal insulation, moisture-proof and waterproof performance. Existing cold storage insulation boards are mostly spliced ​​by inserting grooves and protrusions, and then the gaps are fully glued with sealant. However, due to the large temperature difference between the inside and outside of the cold storage, the insulation board will produce a large deformation during use, destroying the sealant, causing cold leakage between the insulation boards, resulting in a large waste of electricity resources, and also reducing the service life of the cold storage.

[0003] Based on the above technical problems, the present application proposes an energy-saving and environment-friendly polyurethane insulation board for cold storage. Utility Model Content

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1-4 The energy-saving and environment-friendly polyurethane insulation board for cold storage shown in the figure comprises an insulation board body 1 and a connecting strip 2. The insulation board body 1 is a plate structure composed of an inner substrate 11, an insulation layer 12 and an outer substrate 13, and the insulation layer 12 is sandwiched between the inner substrate 11 and the outer substrate 13. Among them, the insulation layer 12 is a polyurethane foam material, the inner substrate 11 and the outer substrate 13 are both color-coated steel plates, and the inner substrate 11 and the outer substrate 13 are both pressed into a wave shape to form reinforcing ribs on the surface of the insulation board body 1 to improve the structural strength of the insulation board body 1.

[0020] like Figure 1-4As shown, the connecting strip 2 is fixed on the right side of the insulation board body 1. The connecting strip 2 is a long strip structure, and a plurality of wedge-shaped clamping strips 21 are symmetrically fixed on the front and rear sides of the connecting strip 2, and the clamping strips 21 extend along the length direction of the connecting strip 2. An anchoring strip 22 is fixed on the left side of the connecting strip 2, and the anchoring strip 22 and the connecting strip 2 are an integral structure, and anchoring plates 23 are fixed in array on both sides of the anchoring strip 22. Among them, the connecting strip 2 and the anchoring strip 22 are both made of hard plastic material, and the distance between the two anchoring plates 23 at the leftmost end is equal to the thickness of the insulation layer 12, so as to realize the pre-positioning of the anchoring strip 22.

[0021] like Figure 1 , Figure 2 As shown, a connection groove 14 is provided at the left end of the insulation board body 1, the depth of the connection groove 14 is greater than the thickness of the connection strip 2, and a card slot 15 matching the card strip 21 is provided on the inner wall of the connection groove 14, and the number of the card slots 15 is greater than the number of the card strips 21. When in use, the connection strip 2 is inserted into the connection groove 14, and the two insulation board bodies 1 are further pressed, so that the card strip 21 is inserted into the card slot 15 as much as possible, thereby forming a pre-tightening force between the two insulation board bodies 1 to avoid the subsequent shrinkage caused by cold and causing the gap to become larger and affect the insulation performance of the cold storage. Preferably, a reinforcing layer 16 of plastic material is installed on the inner wall of the connection groove 14 to ensure the reliability of the connection between the connection strip 2 and the connection groove 14.
