Description

Technical Field

[0001] This invention relates to the field of cold storage panel connection structure technology, specifically to a corner connection structure, panel assembly, and connection method for cold storage insulated panels. Background Technology

[0002] Cold storage is a storage device that creates an environment with different temperature and humidity from the outside to maintain constant temperature and humidity for items such as food, liquids, chemicals, pharmaceuticals, vaccines, and scientific experiments. The connection of the cold storage panels has a very important impact on the insulation effect of the cold storage.

[0003] Currently, there are roughly two connection structures for the corners of cold storage panels in the industry. One method involves pre-embedding concave and convex stops within the panels and connecting them through these stops. This method results in a less tight fit between the panel ends, leading to gaps at the corner joints and causing cold air leakage, thus affecting the refrigeration effect. The other method involves cutting the ends of the two panels at a 45° angle, creating a groove in the center of the joint, and then connecting the two panels using sheet metal corner protectors. Finally, foam material is poured into the grooves for on-site foaming connection. These sheet metal protectors are typically made of ≤1.5mm thick sheet metal, bent and formed, and connected to the cold storage body with rivets. Therefore, the large expansion force of the foam often makes effective on-site fastening impossible, leading to deformation and scrapping of the corner protectors. Furthermore, due to limited on-site construction conditions, the corner sheet metal protectors need to be riveted to the panels on-site. Since cold storage panels are usually quite high, often exceeding 5 meters, this involves working at height, making it difficult to guarantee both the difficulty and the quality of the riveting. Summary of the Invention

[0004] The purpose of this invention is to provide a corner connection structure for cold storage insulation panels, panel components, and connection methods to solve the above-mentioned problems.

[0005] The technical solution adopted in this invention is as follows:

[0006] A corner connection structure for cold storage insulation panels is disclosed, used to connect two panels. The two panels are spliced ​​at an angle, forming a panel seam at the splice. The corner connection structure includes an inner corner set on the inner side of the splice and an outer corner set on the outer side of the splice. An intermediate connecting group is provided on the outer corner, extending along the panel seam direction. The intermediate connecting group includes an intermediate connecting rod and an inner locking part set near one end of the inner corner. An inner connecting part is provided on the inner corner, extending from the inner corner to the outer corner, with an inner locking groove at the extended end. The inner locking part can be locked into the inner locking groove and fixed. Foam material is filled between the panel seam, the intermediate connecting group, and the inner connecting part.

[0007] As a further improvement of the present invention, the intermediate connecting group further includes an outer connecting part disposed on the outer corner. The outer connecting part extends from the outer corner direction to the inner corner direction and the end of the extension is provided with an outer slot. The end of the intermediate connecting rod away from the inner slot is provided with an outer slot. The outer slot can be inserted into the outer slot and fixed.

[0009] As a further improvement of the present invention, a number of intermediate connecting members are evenly distributed along the depth direction of the plate seam.

[0010] As a further improvement of the present invention, an isolation member is provided between two adjacent intermediate connecting members. The isolation member is used to support and isolate the two adjacent intermediate connecting members. The isolation member has an isolation space that connects the plate seam and the groove.

[0011] As a further improved technical solution of the present invention, the isolation member includes an outer isolation member and an inner isolation member. The outer isolation member and the inner isolation member are columnar. The outer isolation member is inserted into an outer slot and its two ends abut against two adjacent intermediate connecting members. The inner isolation member is inserted into an inner slot and its two ends abut against two adjacent intermediate connecting members.

[0014] As a further improvement of the present invention, the intermediate connector is made of POM, PA or PE, and at least one of the inner connector and the outer connector is made of aluminum or stainless steel.

[0015] A cold storage insulation panel assembly includes several panels spliced ​​together in pairs. The splicing surfaces of two adjacent panels are wedge-shaped and form a panel seam. The two adjacent panels are connected by the corner connection structure described above.

[0016] A method for connecting the corner of a cold storage insulation panel, utilizing the aforementioned panel corner connection structure, includes the following steps:

[0017] S1. Cut the ends of the two panels into wedges, and cut grooves on the two wedges.

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0029] If the description of this invention involves orientation (e.g., up, down, left, right, front, back, outside, inside, etc.), then the orientations involved need to be defined. For example, "To clearly express the positions and directions described in this invention, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end," or the paper surface can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not necessary.

[0030] A corner connection structure for cold storage insulated panels, used to connect two panels, such as... Figures 1-3 As shown, the two panels are defined here as a first panel 100 and a second panel 200. The first panel 100 and the second panel 200 are spliced ​​at an angle, forming a panel seam at the splice. The corner connection structure includes an inner corner 1 located on the inner side of the splice and an outer corner 4 located on the outer side of the splice. An intermediate connecting group is provided on the outer corner 4. The intermediate connecting group is located at the panel seam and extends along the direction of the panel seam, connecting the outer corner 4 and the inner corner 1. The intermediate connecting group includes an intermediate connecting rod 701 and a connecting rod 702 located near the inner corner 1. An inner locking part 702 is located near one end of the inner corner 1. An inner connecting part 2 is provided on the inner corner 1. The inner connecting part 2 extends from the inner corner 1 to the outer corner 4 and has an inner locking groove 3 at its extended end. The inner locking part 702 cooperates with the inner locking groove 3 and can be locked into the inner locking groove 3 for fixation. Foaming material is filled between the board seam, the intermediate connecting rod 701, and the inner connecting part 2. After foaming, the first panel 100, the second panel 200, the intermediate connecting group, the inner corner 1, and the outer corner 4 are connected together.

[0031] As an embodiment of the present invention, the intermediate connecting group further includes an outer connecting part 5 disposed on the outer corner 4. The outer connecting part 5 extends from the outer corner 4 to the inner corner 1 and the extended end is provided with an outer slot 6. The end of the intermediate connecting rod 701 away from the inner slot 702 is provided with an outer slot 703. The outer slot 703 cooperates with the outer slot 6. The outer slot 703 can be inserted into the outer slot 6 and fixed. The outer slot 703, the intermediate connecting rod 701 and the inner slot 702 constitute the intermediate connecting member 7. The intermediate connector 7 connects and fixes the outer corner 4 and the inner corner 1, thereby indirectly connecting and fixing the first panel 100 and the second panel 200. Meanwhile, the intermediate connector 7 is made of POM (polyoxymethylene), PA (polyamide), or PE (polyethylene). At least one of the inner connecting part 2 and the outer connecting part 5 is made of aluminum or stainless steel. Specifically, the inner connecting part 2 and the outer connecting part 5 can both be made of aluminum, or both can be made of stainless steel, or only the inner connecting part 2 / outer connecting part 5 can be made of the above materials. As long as the intermediate connector 7 and the inner connecting part 2 / outer connecting part 5 are made of different materials, there will be no cold source transfer between them, so as not to generate cold bridges, thereby avoiding the problem of cold leakage at the panel seam.

[0032] As an embodiment of the present invention, on a plane perpendicular to the plate seam, both the outer snap-fit ​​portion 703 and the inner snap-fit ​​portion 702 are circular, and both the outer snap-fit ​​groove 6 and the inner snap-fit ​​groove 3 are circular grooves. When the outer snap-fit ​​portion 703 is snapped into the outer snap-fit ​​groove 6 and the inner snap-fit ​​portion 702 is snapped into the inner snap-fit ​​groove 3, it has both the compressive and tensile strength of a circular surface and forms a contact limit for the outer snap-fit ​​portion 703 and the inner snap-fit ​​portion 702.

[0033] In one embodiment of the present invention, a groove 8 is provided in the middle of the board seam. The groove 8 is a space formed by cutting the first panel 100 and / or the second panel 200. The groove 8 penetrates the first panel 100 and / or the second panel 200 along the depth direction of the board seam. The intermediate connecting rod 701 is provided at the groove 8. The foaming material is filled in the groove 8.

[0034] At least one limiting groove is provided on the outer connecting part 5 and the inner connecting part 2. The limiting groove is connected to the outer locking groove 6 and the inner locking groove 3. One end of the intermediate connecting rod 701 is inserted into the limiting groove. The limiting groove is used to limit the intermediate connecting rod 701 so that the intermediate connecting rod 701 will not be displaced. Preferably, an outer limiting groove 12 is provided on the outer connecting part 5, and the outer limiting groove 12 is connected to the outer locking groove 6. An inner limiting groove 13 is provided on the inner connecting part 2, and the inner limiting groove 13 is connected to the inner locking groove 3. The two ends of the intermediate connecting rod 701 are respectively inserted into the outer limiting groove 12 and the inner limiting groove 13.

[0035] On a plane perpendicular to the seam, both the outer locking part 703 and the inner locking part 702 are circular. The outer locking groove 6 is a circular groove that mates with the outer locking part 703. The diameter of the outer locking groove 6 is greater than the width of the outer limiting groove 12. The inner locking groove 3 is a circular groove that mates with the inner locking part 702. The diameter of the inner locking groove 3 is greater than the width of the inner limiting groove 13.

[0036] As one embodiment of the present invention, such as Figure 4 As shown, a plurality of intermediate connectors 7 are evenly distributed along the depth direction of the plate seam to enhance the connection strength and uniformity between the inner corner 1 and the outer corner 4.

[0037] As an embodiment of the present invention, an isolation member 9 is provided between two adjacent intermediate connecting members 7. The isolation member 9 is used to support and isolate the two adjacent intermediate connecting members 7. The isolation member 9 has an isolation space that connects the plate seam and the groove 8, so that the foaming material foams to connect the first panel 100 and the second panel 200 together.

[0038] The isolation member 9 includes an outer isolation member and an inner isolation member, both of which are columnar. The outer isolation member is inserted into an outer slot 6 and its two ends abut against two adjacent intermediate connecting members 7. The inner isolation member is inserted into an inner slot 3 and its two ends abut against two adjacent intermediate connecting members 7. An isolation space is formed between two adjacent intermediate connecting members 7, the outer isolation member, and the inner isolation member, connecting the plate seam and the groove 8. The outer isolation member and the inner isolation member can be configured as hollow columnar members.

[0039] An external connecting rod 10 is provided between the outer corner 4 and the outer connecting part 5. The width of the outer connecting part 5 is the same as the width of the board seam, and the width of the outer connecting rod 10 is less than the width of the board seam, so that a gap is formed between the outer connecting rod 10 and the first panel 100 and the second panel 200. Since it is difficult to achieve a completely tight fit at the corner, a gap is set so that the foaming material has room to move during foaming, avoiding problems such as uneven adhesion between the panel and the inner and outer corners 4 caused by the expansion of the foaming material.

[0040] An inner connecting rod 11 is provided between the inner corner 1 and the inner connecting part 2. The width of the inner connecting part 2 is the same as the width of the board gap, and the width of the inner connecting rod 11 is smaller than the width of the board gap. The function of this design is the same as that of the outer connecting rod 10 mentioned above. Specifically, the dimensions of the outer connecting rod 10 and the inner connecting rod 11 can be adjusted and adapted according to the thickness of the first panel 100 and the second panel 200.

[0041] In one embodiment of the present invention, the outer snap-fit ​​part 703, the intermediate connecting rod 701 and the inner snap-fit ​​part 702 are integrally formed, the outer corner 4, the outer connecting rod 10 and the outer connecting part 5 are integrally formed, and the inner corner 1, the inner connecting rod 11 and the inner connecting part 2 are integrally formed, thereby enhancing the connection strength.

[0042] The corner connection structure of the cold storage insulation panel provided by the present invention uses an intermediate connecting group to connect the inner corner 1 and the outer corner 4, and uses foaming material for fixation. The structure is simple, the connection strength is high, no cold bridge is generated, and the fit is tight without gaps, thereby avoiding the problem of cold leakage.

[0043] A cold storage insulation panel assembly includes several panels spliced ​​together in pairs. The splicing surfaces of two adjacent panels are wedge-shaped and form a panel seam. The two adjacent panels are connected by the corner connection structure described above. The wedge-shaped connection structure is more stable and has higher connection strength.

[0044] Specifically, the extension direction of the intermediate connector 7 is parallel to the wedge surface.

[0045] A method for connecting the corner of a cold storage insulation panel, utilizing the aforementioned panel corner connection structure, includes the following steps:

[0046] S1. Cut the ends of the two panels into wedges, and cut grooves 8 on the two wedges.

[0047] S2. The inner corner 1 and outer corner 4 are attached to one of the panels and spliced ​​together. The other panel is spliced ​​together with the wedge surface of the first panel at an angle and then fixed.

[0048] S3. Insert intermediate connectors 7 and spacers 9 sequentially into the inner slot 3 and the outer slot 6 along the direction of the plate seam, wherein the intermediate connectors 7 and spacers 9 are spaced apart.

[0049] S4. Foaming material is poured into the groove 8.

[0050] As a preferred embodiment of the above connection method, the ends of the two panels are wedge-cut at 45°, thereby achieving better force distribution uniformity and applicability.

[0051] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0052] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
