Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a constant temperature and humidity cold storage structure. Background Art

[0002] As a refrigeration equipment, cold storage uses artificial means to create an environment with different temperature or humidity from the outdoor environment. It is a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items. Compared with refrigerators, the two have the same refrigeration principle, but the former has a larger refrigeration area.

[0003] Existing cold storage facilities often use polyurethane panels as insulation panels. These panels are used as side walls and ceiling panels, and the ceiling is treated as a suspended ceiling. When the insulation panels are spliced ​​and fixed to the floor, many gaps form. To fill these gaps and prevent cold air from escaping and hot air from entering, polyurethane foam is often used. This utilizes the low thermal conductivity of polyurethane foam to ensure effective insulation.

[0004] However, the existing polyurethane foaming agent used as a filler for cold storage gaps can achieve a certain insulation effect. However, it is difficult for the foaming agent to completely fill the gaps, so there will always be small gaps, affecting the airtightness of the cold storage, causing cold air to leak inside the cold storage, and affecting the insulation effect of the cold storage. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that after the existing cold storage is installed, there are small gaps, which leads to poor air tightness of the cold storage, cold air leakage in the cold storage, and affects the thermal insulation effect of the cold storage.

The upper part of the partition wall is in contact with the top plate, and a third corner piece is provided at each corner between the top plate and the partition wall. A fourth sealing piece is provided between the third corner piece and the top plate and between the partition wall.

[0013] Furthermore, the constant temperature and humidity cold storage structure also includes a plurality of support columns supported between the top plate and the base, a plurality of support column insulation plates are circumferentially arranged on the outer side surfaces of the support columns, the connection between two adjacent support column insulation plates is covered with a corner plate, and the corner plate is fixedly connected to the two adjacent support column insulation plates, and a fifth seal is arranged between the corner plate and the support column insulation plate.

[0014] Furthermore, a sixth sealing member is provided on both sides of the width direction of each insulation board at the joint of each of the top insulation board and the side wall insulation board that are spliced ​​to each other.

[0015] Furthermore, a first through hole is provided between the two top plate insulation boards spliced ​​together, which passes through the thickness direction of the insulation board.

The other end of the second screw rod is fixed on the roof or purlin, and the top plate insulation board is lifted up under the support of the ceiling mushroom head.

[0017] Furthermore, the first screw rod and the second screw rod are located outside the cold storage, and a sleeve is provided at one end close to the top insulation board, and the sleeve is filled with insulation material.

[0018] Furthermore, a portion of the second screw rod located outside the cold storage structure is provided with a partition in the length direction of the second screw rod, and the second screw rod is then connected through an intermediate piece, and the partition and the intermediate piece are confined within the sleeve.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0035] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] The constant temperature and humidity cold storage structure of the present invention includes: base 1, side wall 2, top plate 3. Figure 1As shown, the base 1 includes a leveling layer 11, a first vapor and moisture barrier 12, an insulation layer 13, a cement mortar cushion 14, a reinforced concrete layer 15, and a self-leveling layer 16, which are arranged in order from bottom to top. The side wall 2 is made up of multiple side wall insulation panels. The side wall 2 is arranged along the circumference of the base 1 and the base 1 is located on one side of the side wall 2 in the thickness direction. The joint between the side wall 2 and the ground is sealed by a first seal 4. Figure 2 As shown, two adjacent side wall insulation boards arranged at an angle are fixedly connected by a first corner piece 5 provided at the inner corner between the two, and a second sealing member 6 is provided between the edge of the first corner piece 5 and the side wall insulation board. Figure 3 As shown, the top plate 3 and the side wall insulation board are fixedly connected by a second corner piece 34 arranged at the inner corner of the two, and a third sealing member 7 is arranged between the second corner piece 34 and the top plate 3 and between the side wall 2.

[0037] In one embodiment, the first seal 4 is made of polyurethane foam; the second and third seals 6 and 7 are cold storage sealant; the first and second corner members 5 and 34 are made of rounded aluminum. The total thickness of the base 1 is 470 mm. The insulation layer 13 comprises six layers laid with staggered joints, with a total thickness of 300 mm. The cement mortar cushion layer 14 is 20 mm thick. The reinforced concrete layer 15 is 150 mm thick and uses C30 concrete. The steel bars are φ10 mm in diameter and arranged at 200 mm intervals in both directions. Epoxy resin is used for self-leveling.

[0038] First, by setting a first moisture-proof vapor barrier layer and a thermal insulation layer 13 on the base 1, moisture from the ground is prevented from entering the cold storage. Secondly, the base 1 is set on one side of the side wall 2 in the thickness direction, and the gap between the side wall 2 and the ground is sealed by the first seal 4 to prevent cold air from overflowing from the gap between the side wall 2 and the ground. Secondly, second seals 6 are set at both ends of the first corner piece 5, so that the cold air in the cold storage is not easy to overflow from the gap between the first corner piece 5 and the side wall 2. Finally, by setting a third seal 7, cold air is prevented from overflowing from the gap between the second corner piece 34 and the top plate 3, and the second corner piece 34 and the side wall 2. The comprehensive use of the above measures enhances the overall airtightness of the cold storage.

[0039] Regarding the connection method of the side wall insulation board at the corner, in one embodiment, as Figure 2As shown, the two side wall insulation panels at the corners are cut at 45° and then spliced, and PU foam is sprayed at the seams. The inner corners of the two side wall insulation panels are connected by the first corner piece 5 as mentioned above. The first corner piece 5 is fixedly connected to the side wall insulation panels by rivets 33 with a model number of φ4mm*13mm. A first outer corner 8 is set at the outer corners of the two side wall insulation panels and the first outer corner 8 is fixed to the outer corner of the side wall insulation panels by rivets 33 with a model number of φ4mm*13mm. In the above manner, while achieving a firm connection of the side wall insulation panels at the corners, the corners of the side wall insulation panels can also maintain good airtightness.

[0040] Regarding the connection between the side wall insulation board and the top plate 3, in one embodiment, as shown in FIG. Figure 3 As shown, an L-shaped groove is provided at the upper end of the side wall insulation board. The height of the L-shaped groove is the same as the thickness of the top plate insulation, and the top plate insulation board is mounted on the L-shaped groove. The top plate insulation board and the side wall insulation board are fixedly connected at the inner corner by the aforementioned second corner piece 34. The second corner piece 34 is fixed by a rivet 33 with a model number of φ4mm*13mm. A second outer corner 9 is provided at the outer corner of the top plate insulation board and the side wall insulation board, and the second outer corner 9 is fixed at the outer corner of the top plate insulation board and the side wall insulation board by a rivet 33 with a model number of φ4mm*13mm. PU foaming is performed at the joint between the top plate insulation board and the L-shaped groove. In this way, the top plate insulation board and the side wall insulation board are firmly connected while maintaining good airtightness.

[0041] In one embodiment, L-shaped positioning angles are set on the ground and fixed to the ground using M6 internal expansion bolts. The positioning angles are pre-arranged on the ground according to the predetermined layout of the side wall insulation panels on the ground, and the side wall insulation panels are laid along the L-shaped positioning angles. The L-shaped positioning angles enhance the stability of the side wall 2 after installation and facilitate the one-time installation of the side wall 2 in the predetermined position, eliminating the need for repeated adjustments to the installation position after installation, thereby improving construction efficiency and ensuring construction quality.

[0042] In order to further prevent the water vapor from the ground from rising and entering the cold storage, in one embodiment, the first vapor and moisture-proof layer 12 is inserted into and fixed to the bottom of the side wall 2, and then the first vapor and moisture-proof layer 12 is bonded to the bottom of the side wall 2 by tape. When the water vapor from the ground rises and reaches the first vapor and moisture-proof layer 12, it moves to the bottom of the side wall 2 under the obstruction of the first vapor and moisture-proof layer 12, and then flows to the outside of the cold storage, preventing the water vapor from entering the cold storage, thereby enhancing the air tightness of the cold storage. In one embodiment, a second vapor and moisture-proof layer 17 is further provided between the thermal insulation layer 13 and the cement mortar cushion layer 14. When a small amount of water vapor passes through the first vapor and moisture-proof layer 12, it is again blocked by the second vapor and moisture-proof layer 17 to prevent the water vapor from entering the cold storage, thereby maximizing the air tightness of the cold storage.

[0043] The constant temperature and humidity cold storage structure of the present invention further includes a partition wall 10, which is used to divide the cold storage structure into multiple independent cold storage units. The temperature of each cold storage unit can be adjusted individually to meet the storage needs of different storage items. Regarding the fixing method of the partition wall 10, in one embodiment, Figure 4 As shown, the upper part of the partition wall 10 is in contact with the top plate 3 and is located at the joint of the two top plate insulation boards. The lower part of the partition wall 10 is positioned by an L-shaped positioning angle to ensure that the partition wall 10 is arranged according to the preset position. A third corner piece 18 is provided at the corner between each top plate 3 and the partition wall 10, and the top plate 3 and the partition wall 10 are connected by the third corner piece 18. In one embodiment, the third corner piece 18 is arc aluminum, and the arc aluminum is fixed by a rivet 33 with a model of φ4mm*13mm. While polyurethane foam is injected into the joint between the partition wall 10 and the top plate 3, a fourth seal 19 is provided between the third corner piece 18 and the top plate 3 and between the partition wall 10. Since the storage items of different cold storage units may be different, the fourth seal 19 is provided to prevent the cold air of different cold storage units from exchanging and affecting each other. In one embodiment, the fourth seal 19 is a cold storage sealant.

[0044] In one embodiment, the cold storage structure further includes a plurality of support columns 20 supported between the top plate 3 and the base 1 to enhance the stability of the cold storage structure. Figure 5 As shown, the outer side of the support column 20 is circumferentially provided with multiple support column insulation panels 21. The junctions between two adjacent support column insulation panels 21 are covered with angled panels 22, which are fixed to the adjacent support column insulation panels 21 using φ4*13 rivets 33. Furthermore, the joints between the support column insulation panels 21 are filled with polyurethane foam, and a fifth sealant 23 is installed between the angled panels 22 and the support column insulation panels 21 to prevent cold air from escaping through the joints between the support column insulation panels 21. In one embodiment, the fifth sealant 23 is made of silicone.

[0045] like Figure 6 As shown, at the joints between adjacent roof insulation boards and at the joints between adjacent side wall insulation boards at non-corner locations, sixth seals 24 are provided on both sides of the insulation boards in the thickness direction to prevent cold air from leaking from the joints. In one embodiment, the sixth seal 24 is a cold storage sealant.

[0046] For the ceiling method of the cold storage top plate 3, such as Figure 7As shown, a first through hole is provided between the two top plate insulation boards that are spliced ​​together, which passes through in the thickness direction of the insulation boards. A first screw rod 25 is provided at one end through the first through hole and partially extends into the interior of the cold storage structure and is connected to an aluminum beam profile 26 located inside the cold storage structure. Since the aluminum beam profile 26 has a strong load-bearing capacity, it can be used as the main load-bearing component of the top plate 3 in this cold storage structure. The other end of the first screw rod 25 is fixed to the roof 27 or the purlin 28, and the top plate insulation board is lifted up under the support of the aluminum beam profile 26. Since the aluminum beam profile 26 includes two wing plates 261 parallel to the top plate insulation board, and the top plate insulation board is supported by the wing plates 261, the top plate insulation board is subjected to more uniform force after being lifted, and the top plate 3 is more stable after being lifted.

[0047] In one embodiment, Figure 7 As shown, the same top plate insulation board is provided with a second through hole that runs through the thickness direction of the insulation board. A second screw rod 29 is provided with one end through the second through hole and partially extends into the interior of the cold storage structure and is connected to a ceiling mushroom head 30 located inside the cold storage structure. The other end of the second screw rod 29 is fixed to the roof 27 or the purlin 28, and the top plate insulation board is lifted under the support of the ceiling mushroom head 30. By lifting the same top plate insulation board through multiple ceiling mushroom heads 30 on the same top plate insulation board, when the top plate insulation board is long, by adding multiple force points in the length direction of the top plate insulation board, the lifting of the top plate insulation board is made more stable. Compared with the aluminum suspension beam profile 26, the ceiling mushroom head 30 is cheaper, which reduces the construction cost of the cold storage structure. At the same time, it avoids the second screw rod 29 from being directly exposed in the cold storage, effectively avoiding the occurrence of cold bridge phenomenon.

[0048] Since the first screw rod 25 and the second screw rod 29 partially extend into the cold storage, when the low temperature is transferred to the part of the screw rod outside the cold storage, a cold bridge will be formed on the screw rod outside the cold storage due to the higher temperature outside the cold storage. At the same time, a large amount of water vapor will liquefy and adhere to the screw rod outside the cold storage, causing the screw rod to rust. In one embodiment, Figure 7 As shown, the first and second screw rods 25, 29 are located outside the cold storage. A sleeve 31 is provided near one end of the top insulation board. Sleeve 31 is filled with insulation material. In one embodiment, the insulation material is polyurethane foam. The sleeve 31 and insulation material isolate the first and second screw rods 25, 29 from the external environment, preventing the occurrence of cold bridges.

[0049] To further reduce the occurrence of cold bridge phenomenon, in one embodiment, Figure 7As shown, the portion of the second screw rod 29 located outside the cold storage structure is provided with a partition in the length direction of the second screw rod 29, and then the second screw rod 29 is connected by an intermediate piece 32, and the partition and the intermediate piece 32 are confined within the sleeve 31. By providing the partition and connecting with the intermediate piece 32, since it is impossible for the screw rod and the intermediate piece 32 to fit smoothly and tightly, there will be a tiny gap on the contact surface between the screw rod and the intermediate piece 32. These gaps will form contact thermal resistance, resulting in energy loss during low temperature transmission, further avoiding the phenomenon of cold bridge on the second screw rod 29.

[0050] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
