Description

Technical Field

[0001] This invention application relates to the field of thermal insulation storage equipment technology, specifically to a profile combination frame, columns, insulation boards, and modular thermal insulation warehouse. Background Technology

[0002] Existing insulated warehouses suffer from several pain points in their structural design and use: First, the warehouse frames are mostly connected by welding or complex bolts, resulting in cumbersome assembly processes that require professional personnel and tools, leading to high after-sales costs. Furthermore, disassembly is difficult, hindering relocation or partial repairs. Second, the sealing design at the joints between the panels and the frame, and between the frame and the columns, is inadequate, easily creating gaps that cause cold bridging, resulting in severe cold leakage, poor insulation, and high energy consumption. Third, the insulation panels often use a single core material, making it difficult to balance compressive strength and lightweight requirements. Additionally, their surface corrosion resistance is insufficient, leading to a short service life in humid, dusty, and other complex environments. Fourth, the warehouse dimensions are fixed, preventing flexible adjustments based on different scenario requirements, and the functional zoning is unclear, limiting adaptability.

[0003] While existing technologies have made some improvements to address the aforementioned problems, they have not yet formed an integrated modular solution encompassing the "frame-column-insulation board" structure. This makes it difficult to simultaneously meet the multiple requirements of sealing and insulation, convenient assembly, robust durability, and flexible adaptability. Therefore, there is an urgent need for a modular insulated warehouse component and structure with a reasonable structural design and comprehensive performance. As one technical solution proposed in this application, Summary of the Invention

[0004] To address the aforementioned issues, this paper provides a composite frame, columns, insulation panels, and modular insulated warehouse, which solves the problems of cumbersome assembly, poor sealing and insulation, insufficient structural stability, and limited adaptability of existing insulated warehouses. This achieves the goals of autonomous and rapid assembly of the warehouse, efficient insulation, sturdiness and durability, and flexible adaptation to multiple scenarios.

[0005] To address the problems of the prior art, this invention application provides a profile composite frame, which is composed of multiple wall panel frames, floor frames and ceiling frames spliced ​​together, wherein each of the wall panel frames, floor frames and ceiling frames includes a mother extruded part and a daughter extruded part;

[0006] The mother extruded part and the daughter extruded part are spliced ​​together by connectors to form a wall panel frame, a floor frame and a ceiling frame.

[0007] The mother extruder is provided with a first groove that adapts to the daughter extruder, the daughter extruder is provided with a first protrusion that matches the first groove, and the contact surface between the mother extruder and the daughter extruder is provided with a first sealing sponge strip mounting position.

[0008] As one technical solution of this application, the mother extruded part and the daughter extruded part are PVC extruded parts with customizable colors, and the sealing sponge strip mounting position is a slot structure extending along the length direction of the inner wall of the first groove or the outer surface of the first protrusion, with a depth of 2-5mm.

[0009] As one technical solution of this application, the connector is a snap-fit ​​connector.

[0010] The present invention also provides a column, wherein both sides of the column are provided with plug-in structures adapted to the mother extrusion part or the daughter extrusion part, for positioning and connecting with the wall panel frame;

[0011] The column is equipped with a second sealing sponge strip installation position at both the top and bottom ends.

[0012] As one technical solution of this application, the plug-in structure is a second groove or a second protrusion extending along the height direction of the column. The groove width and groove depth of the second groove match the size of the first protrusion of the mother extrusion, and the width and height of the second protrusion match the size of the first groove of the daughter extrusion.

[0013] The present invention also provides an insulation board, applied to the aforementioned profile assembly frame, comprising:

[0014] Two panels are inserted at intervals into the inner and outer sides of the profile assembly frame, and the gap between the two panels forms an insulation cavity.

[0015] The insulation core material is filled into the insulation cavity.

[0016] As one technical solution of this application, the insulation core material is polyurethane foam material, and the profile assembly frame is provided with a slot for fitting the edge of the panel, and the edge of the panel is interference-fitted with the slot.

[0017] As one technical solution of this application, the surface of the panel is provided with an anti-corrosion coating.

[0018] The present invention also provides a modular insulated warehouse, which is assembled from the aforementioned profile frame, the aforementioned columns, the aforementioned insulation board, the door frame warehouse panel, and the door warehouse panel frame;

[0019] The profile assembly frame forms the walls, floor and ceiling of the warehouse through the interlocking of the mother extrusion part and the daughter extrusion part. The columns are set at the corners of the profile assembly frame for support and positioning. The insulation board is fixed to the inside of the profile assembly frame to form a closed insulation space.

[0020] The outer sides and top of the door frame panel are spliced ​​together by a mother extruded part and a daughter extruded part. The bottom and inner side of the door frame panel are spliced ​​together by profiles to form an entrance and exit. Insulation panels are installed inside the door frame panel.

[0021] The bottom of the door frame panel is provided with an opening, and the opening of the door frame panel is provided with a long strip-shaped protrusion that can be inserted into the mother extrusion of the floor frame. The two ends of the long strip-shaped protrusion are fixed to the bottom sides of the door frame panel by screws.

[0022] The door panel frame is formed by four profiles, and an insulation board is installed inside the door panel frame. It is hinged to the insulation board on the door frame panel by hinges.

[0023] As one technical solution of this application, a door lock assembly is provided on the insulation plate at the free end of the door panel frame. After the door lock assembly is closed, the contact surface between the door panel frame and the door frame panel is airtightly sealed by a magnetic rubber insulation strip.

[0024] As one technical solution of this application, the external dimensions of the modular insulated warehouse can be selected from various standard specifications; the profile combination frame and the columns are all independent modular structures that can be disassembled and replaced individually.

[0025] The advantages of this invention compared to the prior art are:

[0046] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0047] Reference Figures 1 to 12 As shown: A profile composite frame is formed by splicing multiple wall panel frames 11, floor frames 12 and ceiling frames 13. Each of the wall panel frames 11, floor frames 12 and ceiling frames 13 includes a mother extruded part 15 and a daughter extruded part 16.

[0048] The mother extruded part 15 and the daughter extruded part 16 are spliced ​​together by connectors 17 to form a wall panel frame 11, a floor frame 12 and a ceiling frame 13.

[0049] The mother extrusion part 15 is provided with a first groove 151 adapted to the daughter extrusion part 16, the daughter extrusion part 16 is provided with a first protrusion 161 matching the first groove 151, and the contact surface between the mother extrusion part 15 and the daughter extrusion part 16 is provided with a first sealing sponge strip mounting position 152.

[0050] Profile-based composite frame 1 achieves complete framework construction of the warehouse through differentiated component design:

[0051] The wall panel frame 11, floor frame 12, and ceiling frame 13 are connected by the mother extruded part 15 and the daughter extruded part 16 as the core splicing units.

[0052] Adjacent mother extruded parts 15 or daughter extruded parts 16 are spliced ​​together by connectors 17 to form independent wall panel frames 11, floor frames 12 and ceiling frames 13.

[0053] The wall panel frame 11, floor frame 12, and ceiling frame 13 are positioned by the precise fit between the first groove 151 and the first protrusion 161.

[0054] The ceiling frame 13 is divided into a middle ceiling frame and a side ceiling frame according to the splicing and installation position.

[0055] The ceiling frame 13 in the middle position is connected to the wall panel frame 11 through the mother extrusion part 15 or the daughter extrusion part 16 in the length direction.

[0056] The mother extruded part 15 or the daughter extruded part 16 in the width direction realizes the lateral splicing with the adjacent ceiling frame 13;

[0057] The side ceiling frame 13 is connected to the middle ceiling frame 13 and the wall panel frame 11 by the corresponding mother extrusion part 15 or daughter extrusion part 16, ensuring the overall sealing and structural integrity of the ceiling splicing.

[0058] The floor frame 12 adopts the same splicing logic as the ceiling frame 13, only adjusting the orientation of the mother extruded part 15 or the daughter extruded part 16 that connects with the wall panel frame 11 to face upwards, so as to achieve a precise reverse fit with the wall panel frame 11. Finally, it works together with the wall panel frame 11 and the ceiling frame 13 to form the basic frame structure of the warehouse. At the same time, the first sealing sponge strip installation position 152 is pre-installed with a sponge strip to provide a structural foundation for subsequent overall sealing.

[0059] The first groove 151 and the first protrusion 161 are interlocked to simplify the frame splicing process and improve assembly efficiency; the sealing sponge strip installation position provides a foundation for the subsequent sealing structure and reduces cold bridging; the split frame design adapts to the needs of different warehouse parts and enhances the versatility of the structure.

[0060] Reference Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figures 9-12 As shown: The mother extruded part 15 and the daughter extruded part 16 are PVC extruded parts with customizable colors. The sealing sponge strip mounting position is a slot structure extending along the length direction of the inner wall of the first groove 151 or the outer surface of the first protrusion 161, with a depth of 2-5mm.

[0061] The PVC extruded material combines lightweight and low-temperature resistance, and the color can be customized according to the functional zoning requirements; the slot structure extends along the inner wall of the first groove 151 or the outer surface of the first protrusion 161, providing a precise installation space for the sealing sponge strip. The 2-5mm slot structure depth ensures that the sponge strip is not easy to fall off after installation and can be fully compressed.

[0062] Customizable colors enable visual identification of functional zones, enhancing ease of use; standardized slot structure ensures consistent installation of sealing sponge strips, strengthening the sealing effect; PVC material reduces the overall weight of the frame, facilitating transportation and assembly, while also improving the frame's weather resistance.

[0063] Reference Figure 3 and Figure 5 As shown: The connector 17 is a snap-fit ​​connector 17.

[0064] The snap-fit ​​connector 17 quickly secures the female extruded part 15 and the daughter extruded part 16 by snapping them together, allowing assembly to be completed without additional tools.

[0065] The snap-fit ​​connection simplifies assembly and lowers the barrier to self-installation for users. The detachable design facilitates later maintenance and reduces after-sales costs.

[0066] Reference Figure 1 , Figure 2 , Figure 7 and Figure 13 As shown: The present invention also provides a column, wherein both sides of the column 2 are provided with plug-in structures 21 adapted to the mother extrusion part 15 or the daughter extrusion part 16, for positioning and connecting with the wall panel frame 11.

[0067] The column 2 is provided with a second sealing sponge strip mounting position 22 at both the upper and lower ends.

[0068] The column 2, integrally formed from aluminum profile 141, has high-strength support performance. The plug-in structures 21 on both sides are precisely matched with the mother extrusion part 15 and the daughter extrusion part 16 of the profile combination frame 1 to achieve the positioning connection between the profile combination frame 1 and the column 2. The second sealing sponge strip installation positions 22 at the upper and lower ends of the column 2 are pre-installed with sponge strips to fill the contact gaps between the column 2 and the floor frame 12 and the ceiling frame 13.

[0069] The upright 2 is made of the same material as the mother extruded part 15 and the daughter extruded part 16. The upright 2 improves the reliability of the warehouse support and ensures the stability of the structure. The second sealing sponge strip installation position 22 strengthens the sealing of the upper and lower ends of the warehouse and reduces cold leakage. The positioning connection design ensures that the wall panel frame 11 and the upright 2 are accurately spliced ​​and improves the assembly efficiency.

[0070] Reference Figure 8 and Figure 13 As shown: The plug-in structure 21 is a second groove 211 or a second protrusion 212 extending along the height direction of the column 2. The groove width and groove depth of the second groove 211 match the size of the first protrusion 161 of the mother extrusion 15, and the width and height of the second protrusion 212 match the size of the first groove 151 of the daughter extrusion 16.

[0071] The second groove 211 is precisely matched with the first protrusion 161 of the mother extruded part 15 and the second protrusion 212 is matched with the first groove 151 of the child extruded part 16. Through the interlocking fit, the column 2 and the profile assembly frame 1 are tightly connected, restricting the relative displacement between the two.

[0072] Size adaptability ensures minimal splicing gaps, further improving sealing performance and structural stability; standardized size design facilitates mass production and reduces manufacturing costs; the plug-in mating method eliminates the need for complex fixing structures, simplifying the assembly process.

[0073] Reference Figure 9 and Figure 12 As shown: The present invention also provides an insulation board, applied to the aforementioned profile assembly frame 1, comprising:

[0074] Two panels 31 are inserted at intervals into the inner and outer sides of the profile assembly frame 1, and the gap between the two panels 31 forms an insulation cavity 33.

[0075] The insulation core material is filled into the insulation cavity 33.

[0076] Two panels 31 are spaced apart to form an insulation cavity 33, which improves the insulation effect by utilizing the principle of air insulation. The composite core material has the advantage of being lightweight. The panel 31 is made of color steel, and the color steel panel 31 is attached to the outside of the core material to enhance the structural strength and corrosion resistance of the insulation board 3.

[0077] The composite core material balances compressive strength and lightweight requirements, making it easy to handle and install; the insulation cavity 33 design improves insulation efficiency and reduces energy consumption; the color steel panel 31 extends the service life of the insulation board 3 and is suitable for various application scenarios.

[0078] Reference Figure 9 As shown: the insulation core material is polyurethane foam, and the profile frame 1 is provided with a slot 153 for fitting the edge of the panel 31. The edge of the panel 31 is interference-fitted with the slot 153.

[0079] Polyurethane foam material fills the insulation cavity 33 to further block the heat conduction path; the edge of the panel 31 is interference-fitted with the slot 153 of the profile assembly frame 1 to achieve tight fixation between the panel 31 and the profile assembly frame 1 and avoid gaps.

[0080] Polyurethane foam material enhances the thermal insulation effect of the insulation cavity 33 and strengthens the overall thermal insulation performance; the interference fit design prevents cold leakage at the connection between the panel 31 and the profile frame 1, while also enhancing the installation stability of the panel 31 and preventing it from falling off.

[0081] Reference Figure 15 As shown: The surface of the panel 31 is provided with an anti-corrosion coating 35.

[0082] The anti-corrosion coating 35 covers the surface of panel 31, forming a protective barrier to prevent external corrosive media (such as moisture and chemicals) from contacting panel 31.

[0083] Improve the corrosion resistance of panel 31, extend its service life, and adapt it to complex environments such as humid and dusty environments; reduce the decline in thermal insulation performance of panel 31 due to corrosion damage, and reduce the frequency of maintenance and replacement.

[0084] Reference Figures 1 to 8 , Figure 14 and Figure 16 As shown: The present invention also provides a modular insulated warehouse, which is assembled from the profile 141 combined frame 1, the column 2, the insulation board 3, the door frame warehouse panel 18 and the door warehouse panel frame 14;

[0085] The profile 141 combined frame 1 forms the walls, floor and ceiling of the warehouse body through the insertion and cooperation of the mother extrusion part 15 and the daughter extrusion part 16. The column 2 is set at the corner of the profile 141 combined frame 1 to achieve support and positioning. The insulation board 3 is fixed to the inside of the profile 141 combined frame 1 to form a closed insulation space.

[0086] The outer sides and top of the door frame panel 18 are spliced ​​together by a mother extruded part 15 and a daughter extruded part 16. The bottom and inner side of the door frame panel 18 are spliced ​​together by profiles 141 to form an entrance and exit. The insulation board 3 is installed inside the door frame panel 18.

[0087] The bottom of the door frame panel 18 is provided with an opening, and the opening of the door frame panel 18 is provided with a long strip protrusion 181 that can be inserted into the mother extruded part 15 of the floor frame 12. The two ends of the long strip protrusion 181 are fixed to the bottom sides of the door frame panel 18 by screws.

[0088] The door panel frame 14 is formed by four profiles 141. An insulation board 3 is installed inside the door panel frame 14 and is hinged to the insulation board 3 on the door frame panel 18 via a hinge 142.

[0089] Modular insulated warehouses complete their structural construction through the coordinated operation of multiple components:

[0090] The profile assembly frame 1 is based on the core of the "first groove 151-first protrusion 161" of the "mother extruded part 15-child extruded part 16", and is spliced ​​with connectors 17 to form the walls, floors and ceilings of the modular insulated warehouse, which constitute the basic support structure.

[0091] The uprights 2 are deployed at the corner of the frame and are positioned and connected to the profile combination frame 1 through the plug-in structure 21 on both sides, providing stable support for the warehouse and ensuring overall rigidity; the insulation board 3 is fixed inside the profile combination frame 1 to form a closed insulation space.

[0092] The door frame panel 18 is a differentiated structure of the wall panel. Its outer sides and top are spliced ​​with the mother extrusion part 15 and the daughter extrusion part 16 to ensure compatibility with the wall frame and ceiling frame 13. The bottom and inner side of the door frame panel 18 are spliced ​​with profiles 141 to form an entrance. The profiles 141 have the same structure as the profiles 141 of the door panel frame 14, but their lengths are different according to requirements.

[0093] After the elongated protrusion 181 is fixed to both sides of the bottom of the door frame panel 18 with screws, it is inserted into the mother extruded part 15 of the floor frame 12 to achieve precise positioning and fixation of the door frame panel 18. The combination of the door frame panel 18, the elongated protrusion 181 and the insulation board 3 constitutes the door frame of the modular insulation warehouse.

[0094] The door panel frame 14 is formed by four profiles 141. The door frame panel 18 and the door panel frame 14 are respectively provided with slots 153 for fixing the panel 31. The slots 153 on the door frame panel 18 and the door panel frame 14 have the same structure as the slots 153 on the mother extrusion part 15 and the daughter extrusion part 16, and are all used to fix the insulation board 3. The door panel frame 14 and the insulation board 3 are combined to form the door of the modular insulated warehouse.

[0095] The door panel frame 14 is hinged to the insulation board 3 on the door frame panel 18 via hinge 142, thus completing the movable connection between the door and the modular insulated warehouse body, ultimately forming a modular insulated warehouse.

[0096] Reference Figure 1 , Figure 14 and Figure 16 As shown: A door lock assembly 143 is provided on the insulation board 3 at the free end of the door panel frame 14. After the door lock assembly 143 is closed, the contact surface between the door panel frame 14 and the door frame panel 18 is airtightly sealed by the magnetic rubber insulation strip.

[0097] The door lock assembly 143 is installed on the insulation plate 3 at the free end of the door panel frame 14. When closed, the locking structure of the door lock assembly 143 makes the door panel frame 14 and the door frame panel 18 fit tightly together. At the same time, magnetic rubber insulation strips are provided on the contact surfaces of the door panel frame 14 and the door frame panel 18. The magnetic attraction force enhances the tightness of the fit between the two, and the elastic properties of the rubber material can fully fill the tiny gaps on the contact surfaces, block the cold leakage channels, and achieve an airtight seal in the door area.

[0098] The hinge 142 works in conjunction with the door lock assembly 143 to ensure that the door is easy to open and close and securely shut; the airtight sealing design reduces cold leakage in the door parts and improves the overall thermal insulation performance; the simple and reliable structure reduces the probability of door failure and maintenance costs.

[0099] Reference Figures 1 to 8 and Figure 13 and Figure 14 As shown: the external dimensions of the modular insulated warehouse can be selected from various standard specifications; the profile combination frame 1 and the column 2 are both independent modular structures that can be disassembled and replaced individually.

[0100] Multiple standard sizes are available to meet common storage needs, while customized sizes meet the needs of special scenarios. The standard specifications mentioned above are, for example, starting from 1.36 meters + 136 meters, with each increment of 0.3 meters in length or width constituting a standard size product.

[0101] Multiple size options enhance the adaptability of the warehouse to various scenarios and expand its application scope; the modular disassembly design facilitates warehouse relocation and partial maintenance, reduces usage costs, and increases flexibility.

[0102] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention. Therefore, the protection scope of this invention should be determined by the appended claims.
