Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal insulation structures, in particular to a quick repair structure for a thermal insulation layer of a cold storage. Background Art
[0002] With the rapid development of my country's economy, cold storage has been used more and more in national production. Driven by the government's policy encouragement and the strong demand of the fresh food market, the investment and construction of cold storage, as the core infrastructure of cold chain logistics, has shown a rapid growth trend. However, with the increase in the service life of cold storage, there are more and more old cold storages. Due to the disrepair of cold storage, the insulation layer of the cold storage wall, ceiling, column and other parts often cracks, leaks cold, and freezes. In order to improve the ability of old cold storage to store goods at low temperatures, the user of the cold storage will require that the parts with cracks, leaks cold, and freezes in the insulation layer be repaired in a low temperature environment that does not affect the normal use of the cold storage. The usual cold storage construction adopts the method of directly spraying polyurethane insulation layer on the damaged part. The polyurethane insulation layer is vertically or irregularly bonded to the damaged wall, so that the direct contact area between the newly added insulation layer and the original insulation layer is small, which affects the adhesion between the insulation layers. In a low temperature environment, the insulation layer shrinks and increases the risk of the insulation layer at the incision cracking again. Utility Model Content

[0014] In order to facilitate those skilled in the art to understand the technical solution of the utility model, further description is now made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.
[0015] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.
[0016] Please refer to Figure 1-2 , is a schematic diagram of the overall structure of the cold storage insulation layer rapid repair structure of this embodiment. It should be noted that this embodiment is mainly used for damaged parts of the cold storage civil structure such as the junction between the civil wall and the wall beam, the junction between the wall column and the wall surface, and the inner corner of the ceiling beam. Figure 1 It is used for the quick repair structure of the insulation layer of the cold storage with horizontal wall. Figure 2 It is a schematic diagram of the overall structure when this embodiment is applied to a ceiling structure.
[0017] The quick repair structure of the cold storage insulation layer includes a cyanogen vapor barrier layer 1 tightly laid on the base layer 5 of the damaged part of the insulation layer, which is used to isolate the moisture of the cold storage. Since the cyanogen vapor barrier layer 1 belongs to the original wall structure, when the polyurethane insulation layer is sprayed in layers, there is no need to perform primer spraying again, which saves operation time, shortens the construction period, and improves efficiency. A polyurethane insulation layer 2 with a cross-section that is wide on the outside and narrow on the inside is arranged outside the cyanogen vapor barrier layer 1. The polyurethane insulation layer 2 is a low-temperature resistant polyurethane material that can be foamed and constructed normally under low temperature conditions. The hypotenuse of the polyurethane insulation layer 2 is tightly and evenly fitted with the wall of the damaged part of the base layer. A color steel plate outer protective layer 3 is arranged outside the polyurethane insulation layer 2. The color steel plate outer protective layer 3 completely covers the outer surface of the polyurethane insulation layer 2, and each edge exceeds the original color steel plate 7 by between 100-200mm.
[0018] In this embodiment, the incision of the insulation layer at the original position is expanded outward, and a polyurethane insulation layer structure with a wide outer cross section and a narrow inner cross section is adopted, which increases the contact area between the newly sprayed insulation layer and the original insulation layer, improves the adhesion between the new and old insulation layers, and effectively avoids the risk of the insulation layer at the incision cracking again after the insulation layer shrinks in a low temperature environment. This structure can quickly repair the damaged parts, improve the insulation effect of the cold storage, reduce the energy consumption required for normal use of the cold storage, and achieve the effect of energy saving and environmental protection.
[0019] In this embodiment, several layers of steel mesh 6 are sequentially arranged from the inside to the outside in the polyurethane insulation layer 2 to increase the stability inside the polyurethane insulation layer. In specific implementation, a steel mesh 6 can be arranged every 100 mm.
[0020] like Figure 1 As shown, in some embodiments, the polyurethane insulation layer 2 is fixedly connected to the base layer 5 and the color steel plate outer sheath 3 respectively through a plurality of vertically arranged keel frames 4. The cross section of the keel frame 4 is an I-shaped structure with thick ends and thin middle. The I-shaped structure can increase the attachment surface of the connection at both ends, further improving the overall stability performance.
[0021] In addition, in some embodiments, the outer surface of the polyurethane insulation layer 2 is coated with a fireproof material layer to achieve a fireproof effect.
[0022] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
