Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and in particular relates to a sterile cold storage floor structure. Background Technology

[0002] In shipbuilding, some ship types have high requirements for the hygiene and floor load-bearing capacity of cold storage. Extensive statistics show that hygiene problems in cold storage are largely concentrated on the floor and the junction between the floor and wall panels. Traditional cold storage floors consist of thin metal plates on the top and bottom, with a 10mm thick wooden board and insulation core in the middle, connected by splicing or interlocking joints. These seams are exposed inside the cold storage, easily accumulating dirt and difficult to clean, creating hygiene dead spots. This necessitates optimization of the cold storage floor during the design and construction process. Generally, the design and installation of cold storage floors are relatively mature; however, the hygiene dead spots in traditional cold storage floors easily lead to the growth of harmful microorganisms such as mold, contaminating stored goods. Currently, known solutions are as shown in the attached manual. Figure 2 As shown, the cold storage panel is a prefabricated insulated sandwich panel, consisting of a thin metal plate 100, an insulation core layer 200, a wooden board 300, and a non-slip stainless steel sheet 400 from bottom to top. The insulation core layer 200 is a prefabricated insulated sandwich panel with a male-female groove structure, connected by eccentric hooks 600 embedded in the panel. The joints between adjacent floor panels and between the floor and wall panels are sealed with sealant 500. The drawback of this method is that, considering the flatness of the panels and errors in on-site construction, gaps are unavoidable at these joints. Although these gaps are sealed with sealant, since these joints are exposed to the damp cold storage, the sealant at these joints is prone to cracking or peeling during daily foot traffic or cleaning by cold storage workers. Furthermore, traditional cold storage floors have weak load-bearing capacity and cannot meet the transportation and storage requirements of ships with high cargo storage needs. Meanwhile, increased load on the floor can cause it to deform, accelerating the cracking of the sealant at the joints. Furthermore, the right-angle connection between the floor and wall panels makes it difficult to clean sewage and dirt. All of these factors easily lead to the growth of harmful microorganisms such as mold. Once mold grows in the cold storage, its spores will spread throughout the storage room with the air circulation, contaminating the stored items. Summary of the Invention

[0003] The purpose of this invention is to provide a sterile cold storage floor structure that improves the strength of the cold storage, solves the problem that the cold storage floor is prone to the growth of harmful microorganisms and contaminates the stored items, and facilitates on-site construction.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A sterile cold storage floor structure includes a prefabricated insulated sandwich panel, wherein the prefabricated insulated sandwich panel includes a metal plate, an insulated core layer, and a first layer of wood panels arranged sequentially from bottom to top;

[0006] It also includes eccentric hook locks, where two adjacent prefabricated insulated sandwich panels are connected and locked together by eccentric hook locks;

[0007] It also includes a second layer of wooden boards and a non-slip stainless steel plate. The second layer of wooden boards is glued to the top of the first layer of wooden boards, and the non-slip stainless steel plate is glued to the top of the second layer of wooden boards. The joints of two adjacent non-slip stainless steel plates are fully welded together.

[0008] It also includes a stainless steel curved corner panel, which is located at the junction of the floor and the wall panel. The gap at the curved part is filled with heat insulation filler, and the joint between the stainless steel curved corner panel and the anti-slip stainless steel plate is fully welded.

[0009] It also includes hardwood strips distributed in the insulation core layer.

[0010] Furthermore, it also includes stainless steel strips, which are installed at the edge of the second layer of wood panels, and fasteners pass through the stainless steel strips to reinforce and connect the second layer of wood panels, the first layer of wood panels, and the heat insulation core layer.

[0011] Furthermore, the thickness of both the first and second layer of wooden boards is not less than 10mm.

[0012] Furthermore, the second layer of wood panels is glued to the first layer of wood panels with staggered joints, and the anti-slip stainless steel panels are glued to the second layer of wood panels with staggered joints, with a gap of at least 100mm between each layer.

[0013] Furthermore, the stainless steel arc corner plate is a bent structure with an arc connection, and its two ends are respectively connected to the anti-slip stainless steel plate and the wall panel.

[0014] Furthermore, the hardwood blocks are vertically distributed in the heat insulation core layer, and the distribution spacing is not less than 4 blocks per square meter.

[0015] The advantages and positive effects of this utility model are:

[0016] This invention solves the problems of sealant peeling and mold growth by replacing the original sealant with full welding at all exposed seams of the cold storage floor; it also solves the problem of dirt accumulation and difficulty in cleaning by replacing the original right-angle corners with rounded corner panels; and it increases the strength of the cold storage panels by using double-layer wood boards and hardwood blocks in the insulation core, thus solving the problem of increased floor deformation and gaps leading to dirt accumulation when transporting large quantities of goods. The advantages of this invention are that it ensures the insulation performance of the cold storage while retaining the convenient installation features of prefabricated insulated sandwich panels; the use of full welding at the joints of the anti-slip stainless steel panels instead of the original sealant prevents cracking at the joints; and the change from right-angle joints to rounded transitions at the joints between the floor and wall panels reduces the accumulation of sewage in the corners. This effectively avoids the formation of unsanitary corners in the cold storage, prevents the growth of harmful microorganisms, ensures food safety on ships, and facilitates on-site construction by workers.

[0019] Figure 2 The background art refers to the existing marine cold storage floor structure. Detailed Implementation

[0020] First, it should be noted that the specific structure, features, and advantages of this utility model will be described in detail below by way of examples. However, all descriptions are for illustrative purposes only and should not be construed as limiting the utility model in any way. Furthermore, any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, can still be arbitrarily combined or deleted among these technical features (or their equivalents) to obtain more other embodiments of this utility model that may not be directly mentioned herein. Additionally, for the sake of simplifying the drawings, the same or similar technical features may be indicated only in one place in the same drawing.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0022] like Figure 1As shown, this embodiment provides a sterile cold storage floor structure, including a metal plate 1, a heat insulation core layer 2, and a first-layer wooden board 3. The metal plate 1, the heat insulation core layer 2, and the first-layer wooden board 3 are arranged from bottom to top to form a prefabricated heat insulation sandwich panel 4 with a male and female groove structure; it also includes an eccentric hook lock 5, which is embedded in the prefabricated heat insulation sandwich panel 4, and two adjacent prefabricated heat insulation sandwich panels 4 are connected and locked by the eccentric hook lock 5;

[0023] It also includes a second layer of wood board 6, which is glued to the top of the first layer of wood board 3. A stainless steel strip 7 is installed at the edge of the second layer of wood board 6 by setting a recessed structure. Fasteners 8 pass through the stainless steel strip 7 to fix the first layer of wood board 3, the second layer of wood board 6, and the heat insulation core layer 2 together, which serves to reinforce them again. It should be noted that fasteners here can be fastening screws.

[0024] It also includes an anti-slip stainless steel plate 9, which is bonded to the top of the second layer of wood board 6. The joints of two adjacent anti-slip stainless steel plates 9 are fully welded by cold welding process. It also includes a stainless steel arc corner plate 10 and heat insulation filler 11. The stainless steel arc corner plate 10 is used at the connection between the floor and the wall panel. The gap at the arc is filled by the heat insulation filler 11. The joints are fully welded by cold welding process. It also includes hardwood squares 12, which are distributed in the heat insulation core layer 2.

[0025] It should be noted that all seams on the surface of the cold storage floor are fully welded, eliminating the possibility of cracks at the seams and the accumulation of dirt and sewage.

[0026] In addition, the thickness of both the first layer of wooden board 3 and the second layer of wooden board 6 is not less than 10mm; the anti-slip stainless steel plate 9 is glued to the second layer of wooden board 6 with staggered joints, and the gap between the two is at least 100mm. This staggered installation reduces stress concentration, increases the strength of the floor, reduces deformation of the cold storage floor, and also isolates the heat transfer during cold welding, preventing damage to the insulation core layer.

[0027] Of course, one could consider using stainless steel rounded corner plates to fully weld together the floor and wall panels at the junction to further reduce the risk of accumulating dirt and wastewater and breeding harmful microorganisms in the cold storage. This would reduce the intensity of cleaning work in the corners of the cold storage, while the rounded structure would allow wastewater to drain quickly.

[0028] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
