Technical Field
[0001] The utility model relates to a thermal insulation ceiling structure of an ultra-low temperature cold storage. Background Art
[0002] At present, the temperature of most cold storages in China is between -18 and -25 degrees Celsius. For -55 degrees ultra-low temperature cold storage, a warehouse-in-warehouse form is basically adopted. Usually, civil construction warehouses are more common in ultra-low temperature cold storages, and spray polyurethane is used for top insulation. However, the insulation defects of this single insulation material make it difficult to meet the insulation requirements of -55 degrees ultra-low temperature cold storages. Utility Model Content
[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide an ultra-low temperature cold storage insulation ceiling structure with a reasonable structural design, thereby solving the top insulation problem of the ultra-low temperature cold storage.
[0004] The technical solution adopted by the utility model to solve the above problems is: an ultra-low temperature cold storage insulation ceiling structure, including a hanging assembly, characterized in that it also includes a polyurethane sandwich panel, a polyurethane foam material, a polyurethane board, a color steel plate, an upper hanging plate and a lower hanging plate; the polyurethane sandwich panel is a plurality of pieces, which are laid flat on the top of the ultra-low temperature cold storage, and the plate seam between the two polyurethane sandwich panels is filled with polyurethane foam material, and a lower hanging plate is arranged on the lower surface of the plate seam, and the lower hanging plate is fixed on the polyurethane sandwich panel; the upper hanging plate is connected and fixed to the lower hanging plate; the polyurethane board is fixed on the lower surface of the polyurethane sandwich panel; the polyurethane board is coated with a color steel plate; the hanging assembly is connected to the upper hanging plate.
[0005] The polyurethane sandwich panel described in the utility model is a double-sided color steel polyurethane sandwich panel.
[0006] The utility model provides a plastic-coated plate on the upper surface of the plate seam between two polyurethane sandwich plates, and the plastic-coated plate is fixed on the polyurethane sandwich plate; the upper hanging plate passes through the plastic-coated plate and is connected and fixed with the lower hanging plate.
[0007] The lower hanging plate described in the utility model is in an inverted T shape.
[0008] The upper hanging plate of the utility model is sleeved with a PVC pipe.
[0009] The polyurethane board described in the utility model has the same thickness as the polyurethane sandwich board.
[0010] The hoisting assembly of the utility model comprises a steel wire rope and a turnbuckle bolt, and the steel wire rope is connected with the upper hanging plate through the turnbuckle bolt.
[0011] Compared with the prior art, the utility model has the following advantages and effects:
[0012] 1) Through the combination of polyurethane sandwich panels and polyurethane panels, the insulation defects of single insulation materials are well solved, and the insulation thickness requirements of -55 degree ultra-low temperature cold storage are well met.
[0013] 2) Conventional ultra-low temperature cold storage uses concrete roofs, and there are many columns inside the warehouse, which affects the storage capacity. The utility model improves the thermal insulation effect. The roof of the ultra-low temperature cold storage can adopt a lightweight color steel plate roof, reducing the columns inside the warehouse, thereby achieving the effect of increasing the storage capacity.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0018] The embodiment of the utility model comprises a polyurethane sandwich panel 1, a polyurethane foam material 2, a plastic-coated board 3, a polyurethane board 4, a color steel board 5, an upper hanging board 8, a PVC pipe 9, a lower hanging board 10 and a hanging assembly.
[0019] The polyurethane sandwich panel 1 is a double-sided color steel polyurethane sandwich panel with a thickness of 200mm. There are multiple polyurethane sandwich panels 1, which are laid flat on the top of the ultra-low temperature cold storage. The board seam between the two polyurethane sandwich panels 1 is filled with polyurethane foam material 2 on site, and a plastic-coated board 3 is arranged on the upper surface of the board seam, and the plastic-coated board 3 is fixed to the polyurethane sandwich panel 1 with a core-pulling rivet. A lower hanging board 10 is arranged on the lower surface of the board seam, and the lower hanging board 10 is fixed to the polyurethane sandwich panel 1 with a core-pulling rivet. The upper hanging board 8 passes through the plastic-coated board 3 and is fixed to the lower hanging board 10 by bolts. The lower hanging board 10 is an inverted T-shaped, and its upper part extends into the board seam. The upper hanging board 8 is made of flat steel, and the lower hanging board 10 is made of aluminum. A PVC pipe 9 is sleeved on the upper hanging board 8, and the function of the PVC pipe 9 is to break the cold bridge.
[0020] The polyurethane plate 4 is fixed on the lower surface of the polyurethane sandwich panel 1. The polyurethane plate 4 is as thick as the polyurethane sandwich panel 1 and is also 200 mm thick. The polyurethane plate 4 can be made by spraying on site. A color steel plate 5 is coated on the polyurethane plate 4.
[0021] The thickest polyurethane sheet on the market is about 250mm thick, which is far from meeting the insulation requirements of -55 degree ultra-low temperature cold storage. The combination of the polyurethane sandwich panel 1 and the polyurethane panel 4 of the utility model, the insulation layer of the entire ceiling panel reaches 400mm thick, which can meet the insulation requirements of -55 degree ultra-low temperature cold storage.
[0022] The hoisting assembly is connected to the upper hanging plate 8. The hoisting assembly includes a steel wire rope 6 and a turnbuckle bolt 7, and the steel wire rope 6 is connected to the upper hanging plate 8 through the turnbuckle bolt 7.
[0023] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
