Abstract
The utility model provides a polyurethane cold-storage board, which is characterized in that the two ends and middle of a polyurethane board are respectively provided with a trapezoid groove, the two sides of the trapezoid groove at one end of the polyurethane board are respectively provided with a wedged groove, and the two sides of the trapezoid groove at the other end of the polyurethane board are respectively provided with a wedged boss corresponding to the wedged groove. When the polyurethane board is lapped, a cavity is formed in the middle of the polyurethane board, and then liquid polyurethane is fed into the cavity and solidified, so that the heat preservation effect of the polyurethane cold-storage board is better, and the polyurethane cold-storage board is more suitable to be used in freezers with extremely-low temperatures.
Description
Technical field
The utility model belongs to building materials field, especially relates to a kind of polyurethane freezer plate.
Background technology
In the freezer field; Mostly use polyurethane sheet, and the polyurethane sheet bridging method be adopt box and pin and snap close overlap joint and at the place, slit filling with sealant, such some defectives of structure existence: when being used for ultra low temperature cool house; The non-allied substances of fluid sealant and polyurethane; The difference that has the shrinkage ratio then can occur between plate poorly sealedly, causes heat insulation effect bad.
Summary of the invention
The purpose of the utility model pin provides a kind of polyurethane freezer plate that ultra low temperature cool house uses that is more suitable for.
For solving the problems of the technologies described above; The polyurethane sheet that the utility model adopts: at the polyurethane sheet two ends; A trapezoidal groove is respectively established in the centre, and a wedge-shaped impression is respectively established in end trapezoidal groove both sides, and a wedge shape boss corresponding with wedge-shaped impression is respectively established in other end trapezoidal groove both sides.
During two polyurethane sheets overlap joint, cavity of middle formation is injecting liquid polyurethane, through overexpansion, cooling, curing in the column cavity.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the overlap joint between polyurethane sheet is more tight, and heat insulation effect is better.
Description of drawings
Fig. 1 is the utility model polyurethane freezer plate two ends sketch mapes.
Among the figure:
1, polyurethane sheet 2, wedge-shaped impression 3, trapezoidal groove
4, wedge shape boss
The specific embodiment
As shown in Figure 1; The utility model is a kind of polyurethane freezer plate, and at polyurethane sheet 1 two ends, a trapezoidal groove 3 is respectively established in the centre; A wedge-shaped impression 2 is respectively established in one end trapezoidal groove, 3 both sides, and a wedge shape boss 4 corresponding with wedge-shaped impression 2 is respectively established in other end trapezoidal groove 3 both sides.
The utility model course of work is: during two polyurethane sheet 1 overlap joints, wedge-shaped impression 2 cooperates grafting with wedge shape boss 4, and column cavity of middle formation is injecting liquid polyurethane in the column cavity, after overexpansion, cooling, solidify.
The effect of above-mentioned polyurethane sheet structure makes the connection between polyurethane sheet tightr, better heat preservation, thereby energy conservation.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
