Description

Technical Field

[0001] This utility model relates to the field of isolation belts, and in particular to a novel fireproof, waterproof and heat-insulating isolation belt for cold storage. Background Technology

[0002] A cold storage isolation zone is a facility or structure installed inside a cold storage facility or in an area adjacent to the outside world to achieve spatial separation, functional differentiation, and to prevent the spread of adverse factors such as heat, moisture, and dust. For example, an airtight isolation zone can prevent air leakage, maintain stable air pressure inside the cold storage, and prevent moisture from entering the cold storage and causing problems such as frost and ice formation. At the same time, it can also prevent cold air leakage inside the cold storage and reduce cold loss. Generally, materials and structures with good sealing performance, such as sealing strips made of rubber and plastic, and airtight doors, are used as components of the airtight isolation zone.

[0003] In normal use, if the insulation performance of existing cold storage facilities is poor, frequent heat exchange between the inside and outside of the cold storage will occur. The refrigeration system of the cold storage needs to run continuously to maintain the low temperature, which will increase energy consumption. Ineffective insulation will make it difficult to maintain a stable temperature inside the cold storage, resulting in large temperature fluctuations. This will have a significant impact on the quality of refrigerated goods. Furthermore, under long-term high-load operation, the wear and tear of the refrigeration equipment components will be accelerated, thereby shortening the service life of the equipment.

[0004] Therefore, given that the poor insulation performance of existing cold storage facilities leads to frequent heat exchange between the inside and outside of the cold storage, increasing energy consumption, and the inability to effectively insulate affects the quality of refrigerated goods, and shortens their service life under long-term high-load operation, a new type of fireproof, waterproof, and heat-insulating isolation belt for cold storage can be designed to accelerate the construction of fireproof, waterproof, and heat-insulating structures and improve the practicality of the isolation belt. Utility Model Content

[0005] In order to overcome the problems that poor insulation performance of existing cold storage facilities leads to frequent heat exchange between the inside and outside of the cold storage, increasing energy consumption, and that ineffective insulation affects the quality of refrigerated goods and shortens their service life under long-term high-load operation.

[0006] The technical solution of this utility model is as follows: a novel fireproof, waterproof and heat-insulating isolation strip for cold storage, including a fireproof board and a U-shaped mounting frame; the fireproof board is fitted with a U-shaped mounting frame, a waterproof board is provided below the fireproof board, and a heat-insulating board is provided below the waterproof board.

[0007] Furthermore, a first loop-shaped snap-fit ​​strip is installed at the lower edge of the fireproof board, and a first loop-shaped snap-fit ​​groove is opened on the upper part of the waterproof board corresponding to the first loop-shaped snap-fit ​​strip.

[0008] Furthermore, the first snap-fit ​​strip drives the waterproof membrane to be positioned and snapped into the fireproof membrane along the first snap-fit ​​groove.

[0009] Furthermore, a second loop-shaped snap-fit ​​strip is installed at the lower edge of the waterproof membrane, and a second loop-shaped snap-fit ​​groove is opened on the upper part of the insulation board corresponding to the second loop-shaped snap-fit ​​strip.

[0010] Furthermore, the second snap-fit ​​strip drives the waterproof membrane to be positioned and snapped into the insulation board along the second snap-fit ​​groove.

[0011] Furthermore, plug-in blocks are symmetrically installed at both ends of the U-shaped mounting frame, and a rectangular mounting plate is provided on one side of the U-shaped mounting frame. Plug-in slots are opened at both ends of the rectangular mounting plate corresponding to the plug-in blocks, and a fixing strip is vertically inserted through the middle of the plug-in blocks.

[0012] Furthermore, the plug-in block drives the U-shaped mounting frame to be positioned and engaged with the rectangular mounting plate through the plug-in slot.

[0013] The beneficial effects of this utility model are as follows: The fireproof board is sequentially bonded and assembled with the waterproof board and insulation board below, and then reinforced by the U-shaped mounting frame and the rectangular mounting plate on one side. Then, the U-shaped mounting frame drives the fireproof board and other components to be placed in the expansion joints, floor beams, and between the insulation material and the cold storage structure, such as between the cold storage expansion joints, floor beams, the top of the cold storage, and the walls. In this way, the isolation strip is laid between the insulation material and the cold storage structure to form a fireproof and heat-insulating isolation layer. It can effectively prevent the spread of fire, isolate the insulation material from the items inside the cold storage, prevent the fire from spreading from the insulation layer to the inside of the cold storage, and at the same time, it also has excellent heat insulation properties and prevents the formation of cold bridges.
