Description

Support components, thermal insulation support structure and membrane container

[0001] Related applications

[0002] This application claims priority to Chinese patent application No. 202411635355.8, filed on November 15, 2024, and incorporates the disclosure of the aforementioned patent application as part of this application. Technical Field

[0003] This disclosure relates to the field of cryogenic medium storage container technology, and in particular, to a support component, an insulating support structure, and a thin-film container. Background Technology

[0004] A membrane tank is a storage container that isolates the cryogenic medium inside the tank from the external atmospheric environment. It can hold cryogenic liquid hydrogen, cryogenic liquid oxygen, cryogenic LNG, cryogenic ethylene, cryogenic ethane, cryogenic liquid ammonia, cryogenic propane, cryogenic propylene, cryogenic butane and other liquids at near-normal pressure. Therefore, membrane tanks must ensure that the cryogenic medium does not leak (i.e., ensure liquid tightness and air tightness) while minimizing the loss of cold energy of the medium inside the tank.

[0005] Membrane tanks generally consist of three core structures: a strong and rigid outer tank, a flexible inner tank made of a metal membrane, and an insulating support structure located between the flexible inner and outer tanks. The outer tank is primarily responsible for supporting the tank body and ensuring its strength and rigidity; the inner tank is responsible for the liquid and gas tightness of the membrane tank; and the insulating support structure is responsible for transferring the load of the stored medium from the inner tank membrane to the outer tank, while also isolating the low-temperature medium from heat transfer from the external environment.

[0006] Existing thermal insulation support structures are mainly divided into the following two categories:

[0007] One type uses load-bearing insulation materials to directly form the insulation support layer, such as high-density reinforced polyurethane foam and fiber-reinforced polyurethane foam, thus combining the functions of support and insulation. However, because the insulation material is required to have both a low insulation coefficient and high compressive strength, it is difficult to improve the upper limit of the load-bearing capacity and insulation performance of this type of insulation support structure. Furthermore, the temperature difference between the inner and outer areas of the insulation support layer is large, which can easily cause uneven bending due to temperature stress, resulting in gaps of varying sizes between the insulation support layer and the support surface, and ultimately causing support failure.

[0008] Another type is a rigid support structure formed by connecting two rigid plates with multiple rigid pillars, combined with a filled insulation layer formed by non-load-bearing insulation material (such as expanded perlite, low-density polyurethane foam, etc.) between the two rigid plates. Although insulation performance can be improved by using non-load-bearing but low thermal conductivity insulation materials, and by increasing the number of rigid pillars and structural strength, the thermal conductivity of rigid pillars is much greater than that of insulation materials. This will increase the area of ​​cold bridges and reduce the filling space of insulation materials, thereby weakening the insulation area of ​​the filled insulation layer and limiting the improvement of insulation performance. Summary of the Invention

[0009] The purpose of this disclosure is to provide a support component, an insulating support structure, and a thin-film container to solve the technical problem that it is difficult to simultaneously improve the insulating performance and load-bearing capacity of current insulating support structures.

[0010] The above-mentioned objectives of this disclosure can be achieved by the following technical solutions:

[0011] This disclosure provides a support assembly, including a thermally insulated support structure and two support members. A thermally insulated gap exists between the two support members. One support member is positioned near the load application side, and the other support member is positioned near the load-bearing side. The support member positioned near the load application side is supported by the thermally insulated support structure on the support member positioned near the load-bearing side. The cross-sectional area of ​​the thermally insulated support structure is smaller than the cross-sectional area of ​​each support member, thereby reducing the heat transfer area between the two support members; and / or the length of the thermally insulated support structure is greater than the direct connection length between the two support members, thereby increasing the heat transfer path between the two support members. In other words, by introducing the thermally insulated support structure, the total length of the two support members and the thermally insulated support structure is greater than the direct connection length between the two support members, thereby increasing the heat transfer path between the two support members.

[0016] In embodiments of this disclosure, the suspension support structure further includes a suspension support seat, and the second tension portion of the suspension support member is connected to a support member through the suspension support seat.

[0017] In the embodiments of this disclosure, a support member and a suspension support seat are provided with a matching ball socket and a ball head, one of which is provided at one end of the support member and the other is provided at the suspension support seat.

[0018] In embodiments of this disclosure, at least one support member has a threaded connection structure at the end away from the thermal insulation support structure.

[0019] In the embodiments of this disclosure, when the load transfer direction of the two support members is horizontal, the support member closer to the load application side is connected to a fixed structure above through a suspension positioning member, so that the support member closer to the load application side is supported horizontally on the support member closer to the load bearing side through the suspension support structure.

[0020] In the embodiments of this disclosure, an insulating intermediate layer is formed by filling the insulating gap with insulating material, and the insulating intermediate layer can adaptably deform by utilizing its resilience during the relative translation of the two supports.

[0021] In the embodiments of this disclosure, one end of a support member is provided with a mounting groove, and one end of another support member extends into the mounting groove and forms a heat insulation gap with the inner wall surface of the mounting groove. The heat insulation support structure is installed in the mounting groove and connects the two support members; or the ends of the two support members that are close to each other are provided with mounting grooves, and the ends of the two support members that are close to each other are inserted into each other's mounting grooves so that the mounting grooves of the two support members are connected to form a heat insulation gap. The heat insulation support structure is installed in the heat insulation gap and connects the two support members.

[0022] In the embodiments of this disclosure, the support member near the load application side is provided with at least one first spare support part, and the support member near the load bearing side is provided with at least one second spare support part.

[0027] This disclosure also provides a membrane container, including the above-mentioned heat-insulating support structure. The membrane container also includes an inner membrane tank and an outer membrane tank, with the heat-insulating support structure disposed between the inner membrane tank and the outer membrane tank.

[0028] The features and advantages of this disclosure are:

[0029] The support assembly disclosed herein includes one support member supported by a thermally insulated support structure on another support member. By setting a thermally insulated gap between the two support members, the load-bearing capacity is ensured while the thermally insulated gap prevents direct heat transfer between the two support members. The thermally insulated support structure also increases the heat transfer path between the two support members and / or reduces the heat transfer area between them, thereby reducing heat transfer between the two support members and reducing the area of ​​cold bridges.

[0030] The support assembly disclosed herein improves the adaptability and adjustability of the support assembly by setting the thermal insulation support structure as a suspended support structure to suspend one support member on another support member, so that the two support members can translate relative to each other in the direction perpendicular to the load transmission direction.

[0031] The disclosed support assembly utilizes tension cables as suspension supports. Compared to other types of suspension supports, tension cables are lightweight and provide sufficient load-bearing capacity under the tension of the two supports. This sufficient axial tension completely eliminates the interaction between the supports and the surrounding insulation structure, preventing mutual damage under external loads. Furthermore, the shape of the tension cables can adaptively change during load transfer, further enhancing the adaptability of the support assembly. Since the two supports can translate relative to each other, when a horizontal seismic force forces relative movement between them, the tension cables can reduce the effect of the horizontal seismic load through deformation, achieving seismic isolation and damping effects.

[0032] The thermal insulation support structure and membrane container disclosed herein enhance the load-bearing capacity by utilizing the support components of this disclosure, while ensuring that the structural design and material selection of the thermal insulation structure are not limited by the support components, thereby not limiting the improvement of thermal insulation performance.

[0033] The thermal insulation support structure and membrane container disclosed herein utilize the adaptability of the support components to prevent mutual damage between the thermal insulation structure and the support components under load, thereby simultaneously improving load-bearing capacity and thermal insulation performance. Furthermore, when the membrane plate of the membrane container experiences relative displacement between the two support components due to uneven thermal shrinkage, the tension cable can also enhance the displacement compensation capability of the membrane plate through deformation.

[0049] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0050] Implementation Method 1

[0051] As shown in Figure 1, this disclosure provides a support assembly 1, including a thermal insulation support structure 14 and two support members 10. The two support members 10 (i.e., the first support member 11 and the second support member 12) have a thermal insulation gap 13 between them. One support member 10 is disposed near the load application side, and the other support member 10 is disposed near the load bearing side. The support member 10 disposed near the load application side is supported on the support member 10 disposed near the load bearing side by the thermal insulation support structure 14. The thermal insulation support structure 14 is configured to reduce the heat transfer area between the two support members 10 and / or increase the heat transfer path between the two support members 10.

[0052] Specifically, the heat transfer area between the two support members 10 can be reduced by decreasing its cross-sectional area, i.e., the cross-sectional area of ​​the heat transfer support structure 14 is smaller than the cross-sectional area of ​​each support member 10; and / or the heat transfer path between the two support members 10 can be increased by increasing its length, i.e., the length of the heat transfer support structure 14 is greater than the length of the direct connection between the two support members 10. In other words, by introducing the heat transfer support structure 14, the total length of the two support members 10 and the heat transfer support structure 14 is greater than the length of the direct connection between the two support members 10, thereby increasing the heat transfer path between the two support members 10.

[0053] Furthermore, it should be noted that, for ease of description, the support member 10 positioned near the load application side is defined as the first support member 11, and the support member 10 positioned near the load-bearing side is defined as the second support member 12. The first support member 11 is supported on the second support member 12 by a thermal insulation support structure 14. That is, the first support member 11 and the second support member 12 are arranged along the load transfer direction F. The load on the load application side is first transferred to the first support member 11, then transferred to the second support member 12 through the thermal insulation support structure 14, and finally transferred to the load-bearing side by the second support member 12. In this disclosure, the structural shapes of the two support members 10 can be the same or different, but any support member 10 is not limited to being the first support member 11 or the second support member 12. Rather, it can be selectively positioned near the load application side as the first support member 11, or selectively positioned near the load-bearing side as the second support member 12.

[0054] The support assembly 1 disclosed herein includes one support member 10 supported by another support member 10 via a thermally insulated support structure 14. A thermally insulated gap 13 is provided between the two support members 10. This ensures load-bearing capacity while preventing direct heat transfer between the two support members 10. Furthermore, the thermally insulated support structure 14 increases the heat transfer path between the two support members 10 and / or reduces the heat transfer area, thereby reducing heat transfer between the two support members 10 and minimizing the area of ​​cold bridges. In addition, compared to the integrated support rods or columns in the prior art, the two separate support members 10 in this disclosure have a shorter stress length in the load transfer direction F, thus reducing the risk of instability.

[0055] Therefore, the support component 1 disclosed herein is particularly suitable for use in equipment requiring insulation, including but not limited to cryogenic medium storage containers such as thin-film containers. Referring to Figures 1, 12, and 13, in this embodiment, the support component 1 provides support between the inner film tank 200 and the outer tank 300 of the thin-film container, allowing the load of the stored medium in the inner film tank 200 to be transferred to the outer tank 300 via the support component 1, and reducing heat transfer via the support component 1. Specifically, the end of the first support member 11 near the load application side supports the inner film tank 200 of the thin-film container via the support plate structure 3, and the end of the second support member 12 near the load bearing side is fixed to the outer tank 300 of the thin-film container. An insulating space is formed between the support plate structure 3 and the outer tank 300. By filling the insulating space with insulating material, an insulating structure 2 is formed, and the support component 1 passes through the insulating structure 2.

[0056] As shown in Figures 1 to 3, in the embodiments of this disclosure, the shape and size of the two support members 10 are not specifically limited, and can be set according to the requirements; the ends of the two support members 10 that are close to each other (i.e. the end of the first support member 11 away from the load application side and the end of the second support member 12 away from the load bearing side) do not contact each other, thereby forming a heat insulation gap 13.

[0057] As shown in Figure 1, in some embodiments of this disclosure, one end of a support member 10 is provided with a mounting groove 121, and one end of another support member 10 extends into the mounting groove 121, forming a heat-insulating gap 13 between the support member 10 and the inner wall of the mounting groove 121. A heat-insulating support structure 14 is installed in the mounting groove 121 and connects the two support members 10. In a specific embodiment, both support members 10 are generally rod-shaped structures, wherein one support member 10 (e.g., the second support member 12) is a hollow rod structure, thereby forming a mounting groove 121 using its inner cavity, and one end of the other support member 10 (e.g., the first support member 11) extends into the mounting groove 121, forming a heat-insulating gap 13 between the support member 11 and the inner wall of the mounting groove 121. The heat-insulating support structure 14 is installed in the mounting groove 121 and connects the two support members 10.

[0058] As shown in Figures 2 and 3, in some other embodiments of this disclosure, each of the two support members 10 has a mounting groove 121 at one end close to each other. The two support members 10 are inserted into each other's mounting grooves 121, so that the mounting grooves 121 of the two support members are connected to form a heat insulation gap 13. The heat insulation support structure 14 is installed in the heat insulation gap 13 and connects the two support members. In one specific embodiment, both support members 10 are generally U-shaped plates, and the mounting grooves 121 are formed by the grooves of the U-shaped plates. In another specific embodiment, one support member 10 is equivalent to multiple U-shaped plates spliced ​​along its planar direction, and the other support member 10 is equivalent to multiple U-shaped plates arranged at intervals and connected along its thickness direction. As shown in Figures 1 to 3, in the embodiments of this disclosure, the heat insulation support structure 14 is a suspension support structure, and the first support member 11 is suspended and supported on the second support member 12 through the suspension support structure. By setting the thermal insulation support structure 14 as a suspended support structure, one support member 10 is suspended and supported on another support member 10, so that the two support members 10 can translate relative to each other in the direction perpendicular to the load transmission direction, thereby improving the adaptability and adjustment capability of the support assembly 1.

[0059] Specifically, since the two support members 10 can translate relative to each other, when a horizontal seismic force forces the two support members 10 to move relative to each other, the suspension support structure can reduce the effect of the horizontal seismic load by swinging and / or deforming, thus achieving the effects of seismic isolation and vibration reduction. Furthermore, as shown in Figures 12 and 13, when the support assembly 1 of this disclosure is applied to a membrane tank container, when the membrane plate 201 experiences relative displacement between the two support plates 31 due to uneven thermal shrinkage, the suspension support structure can also improve the displacement compensation capability of the membrane plate 201 by swinging or deforming. In addition, a limiting structure can be set as needed to restrict the relative translational direction of the two support members 10 and guide the two support members 10 to move relative to each other in a preset translational direction, thereby directionally improving the displacement compensation capability.

[0060] As shown in Figure 1, in the embodiments of this disclosure, the insulation gap 13 can be filled with insulation material to form an insulation intermediate layer, thereby further improving the insulation effect and reducing heat transfer. In order to avoid the insulation intermediate layer affecting the relative translation of the two support members 10, the insulation intermediate layer can be filled with a soft, resilient, and low thermal conductivity insulation material (such as high-elasticity polyurethane, expanded perlite foam, flexible glass wool felt, aerogel, etc.), so that the insulation intermediate layer can adaptably deform by utilizing its resilience during the relative translation of the two support members 10.

[0061] As shown in Figures 2 to 4, in embodiments of this disclosure, the suspension support structure includes at least one suspension support member 141. The suspension support member 141 has at least one first tension-bearing portion 1414 and at least one second tension-bearing portion 1415 with opposite tension directions. For example, in the embodiments shown in Figures 2 to 7, the tension force on the first tension-bearing portion 1414 is upward, and the tension force on the second tension-bearing portion 1415 is downward; of course, in other embodiments of this disclosure, the tension force on the first tension-bearing portion 1414 is downward, and the tension force on the second tension-bearing portion 1415 is upward.

[0062] In some embodiments of this disclosure, the first tension portion 1414 of the suspension support 141 is connected to a support 10, and the second tension portion 1415 of the suspension support 141 is connected to another support 10. As shown in Figures 1 and 4, the first tension portion 1414 or the second tension portion 1415 can be directly connected to the corresponding support 10, or, as shown in Figure 7, can be connected to the corresponding support 10 via a suspension support seat 142. As shown in Figures 2 and 3, in other embodiments of this disclosure, there are multiple suspension supports 141, including at least one first suspension support 141 and at least one second suspension support 141'. The first tension portion 1414 of the first suspension support 141 is connected to a support 10, the second tension portion 1415 of the first suspension support 141 is connected to the first tension portion 1414 of the second suspension support 141', and the second tension portion 1415 of the second suspension support 141' is connected to another support 10. Both the support member 10 and the suspension support seat 142 are provided with a connection structure 123 for connecting with the suspension support member 141. The connection structure 123 includes, but is not limited to, hooks, buckles, rings, and holes.

[0063] As shown in Figures 2 to 5, in some embodiments of this disclosure, the suspension support 141 includes at least one tension cable 1411, that is, the tension cable 1411 forms a suspension structure to suspend the first support 11 on the second support 12. The tension cable 1411 provides sufficient load-bearing capacity under the tension of the two support members 10. It provides sufficient load-bearing capacity through sufficient axial tension, and can also eliminate the interaction between the support member 10 and the surrounding thermal insulation structure 2, avoiding mutual destruction of the support member 10 and the surrounding thermal insulation structure 2 under load. In addition, the tension cable 1411 has a certain deformation capacity so that its shape can adaptably change during load transmission, thereby further improving the adaptability and adjustment capability of the support assembly 1. The tension cable 1411 can be made of at least one of the following high-strength, low-thermal-conductivity materials: carbon fiber, aramid fiber, ultra-high molecular weight polyethylene fiber, basalt fiber, and glass fiber. This ensures that the tension cable 1411 meets the required load-bearing capacity under tension and that its thermal conductivity is significantly lower than that of direct heat conduction between the two support members 10, thereby further reducing heat transfer. Alternatively, other materials, such as metal rope or chain structures, can be selected based on the load-bearing requirements.

[0064] As shown in Figures 5 to 7, in some optional embodiments of this disclosure, the suspension support structure is provided with only one suspension support member 141, which is provided with only one tension cable 1411, and the tension cable 1411 is a ring-shaped tension cable 1412, thereby ensuring that the tension cable 1411 is subjected to uniform force at all points and can be adaptively adjusted to the optimal force state. In one specific embodiment, the ring-shaped tension cable 1412 can form a plurality of first tension portions 1414 and a plurality of second tension portions 1415 arranged in an alternating manner in its circumferential direction; wherein, the number of first tension portions 1414 and second tension portions 1415 can both be selected as three or more. In another specific embodiment, the ring-shaped tension cable 1412 is woven to form a cable net structure.

[0065] As shown in Figures 2 and 3, in some other embodiments of this disclosure, the suspension support structure may be provided with multiple suspension support members 141, and each suspension support member 141 may be provided with one or more tension cables 1411. Alternatively, as shown in Figure 4, the suspension support structure may be provided with only one suspension support member 141, and this suspension support member 141 has multiple tension cables 1411, so that the number of tension cables 1411 in the suspension support structure is multiple. As shown in Figures 2 to 4, in some specific embodiments, the multiple tension cables 1411 are woven to form a cable net structure 1413. In another specific embodiment, the multiple tension cables 1411 are evenly arranged around the center of gravity of the first support member 11, and the two ends of the tension cables 1411 form a first tension portion 1414 and a second tension portion 1415.

[0066] The cable net structure 1413 in the above embodiment has multiple first tension portions 1414 in its edge region and at least one second tension portion 1415 in its internal region. The number of first tension portions 1414 can be three or more, while only one second tension portion 1415 can be provided, optionally located at the center of the cable net structure 1413. Furthermore, the cable net structure 1413 can optionally be net-shaped, providing good load-bearing capacity, and the tension cables 1411 can be longer, thereby more effectively increasing the heat transfer path between the two support members 10.

[0067] In some other embodiments of this disclosure, the suspension support 141 may also be a suspension support rod or a hook, etc.

[0068] As shown in Figure 1, in the embodiments of this disclosure, when the load transfer direction of the first support member 11 and the second support member 12 is vertical, since the load transfer direction is the same as the gravity direction of each structure, the first support member 11 can maintain a vertical state and be supported on the second support member 12 by the heat insulation support structure 14. However, as shown in Figure 8, when the load transfer direction of the first support member 11 and the second support member 12 is horizontal, in order to avoid the first support member 11 and its connected support plate structure 3 from deviating from the support position due to the influence of gravity, the first support member 11 is suspended on the fixed structure above by the suspension positioning member 16, so that the first support member 11 is supported horizontally on the second support member 12 by the suspension support structure. The fixed structure is not specifically limited, as long as it is a fixedly installed structure. For example, it can be the second support member 12' fixed on the bearing plate structure 301 in another support component 1, or other support members fixedly installed on the bearing plate structure 301 in the prior art, such as support rods, support blocks, etc., or it can be the bearing plate structure 301 itself.

[0069] As shown in Figure 1, in the embodiments of this disclosure, the first support member 11 and / or the second support member 12 are rotatably arranged relative to the suspension support structure, thereby further improving the adaptability and adjustability of the support assembly 1. Referring to Figures 7 and 9, in some embodiments of this disclosure, a support member 10 and a suspension support seat 142 are provided with a matching ball socket 1421 and a ball head 111, one of which is located at one end of the support member 10 (e.g., the end of the first support member 11 away from the load application side or the end of the second support member 12 close to the load application side), and the other is located at the suspension support seat 142. Referring to Figures 1 and 9, in some embodiments of this disclosure, a support member 10 is provided with a ball head 111 at one end near another support member 10 (for example, the end of the first support member 11 away from the load application side or the end of the second support member 12 near the load application side). The ball head 111 contacts the cable net structure 1413, so that the support member 10 can rotate relative to the cable net structure 1413, and can also prevent the support member 10 from damaging the cable net structure 1413.

[0070] As shown in Figure 9, in the embodiments of this disclosure, at least one support member 10 has a threaded connection structure 15 at its end away from the heat insulation support structure 14. Specifically, referring to Figures 10 and 11, the first support member 11 is connected to a support plate structure 3 via the threaded connection structure 15, and / or the second support member 12 is connected to a load-bearing plate structure 301 via the threaded connection structure 15. The position of the support plate structure 3 in the load transmission direction F can be adjusted by rotating the first support member 11 and / or the second support member 12. Furthermore, by connecting the support plate structure 3 and the load-bearing plate structure 301 with at least three support components 1, the angle of inclination of the support plate structure 3 relative to the vertical direction of the load transmission direction can be adjusted.

[0071] As shown in Figures 9 and 10, in some embodiments of this disclosure, the threaded connection structure 15 includes a matching external threaded surface 151 and an internal threaded hole 152. The external threaded surface 151 is disposed on the first support member 11. The internal threaded hole 152 can be directly formed on the support structure or formed on a threaded sleeve 154, which is embedded and fixed to the support plate structure 3. Furthermore, one end of the first support member 11 passes through the support plate structure 3 and is provided with a leveling connector 153 for connecting a rotating tool (such as a wrench), so that the position of the support plate structure 3 can be adjusted by rotating the first support member 11. Referring to Figure 11, in other embodiments of this disclosure, the external threaded surface 151 can be disposed on the second support member 12. The internal threaded hole 152 can be directly formed on the bearing plate structure 301 or formed on a threaded sleeve 154, which is embedded and fixed to the bearing plate structure 301.

[0072] Referring to Figures 2 and 3, in the embodiments of this disclosure, the support member 10 near the load application side is provided with at least one first spare support portion 112, and the support member 10 near the load bearing side is provided with at least one second spare support portion 122. The first spare support portion 112 and the second spare support portion 122 are separately arranged in the load transmission direction F of the two support components 1, that is, separated by a certain distance. In the state of failure of the thermal insulation support structure 14, the first spare support portion 112 can be supported on the second spare support portion 122, so that after the thermal insulation support structure 14 fails, for example, if the tension cable 1411 breaks, the support component 1 can still be connected to the first support member 11 and the second support member 12 through the first spare support portion 112 and the second spare support portion 122, thereby still having a certain load-bearing capacity. Specifically, one of the first spare support portion 112 and the second spare support portion 122 can be generally in the form of a rod-shaped structure, and the other can be generally in the form of a groove structure.

[0073] Implementation Method 2

[0074] Referring to Figures 1 and 11 to 13, this disclosure also provides a thermal insulation support structure 100, including at least one support component 1; the thermal insulation support structure 100 further includes a thermal insulation structure 2, and the support component 1 passes through the thermal insulation structure 2. In this embodiment, the support component 1 has the same specific structure, working principle, and beneficial effects as the support component 1 in Embodiment 1, and will not be described again here.

[0075] The thermal insulation support structure 100 disclosed herein enhances the load-bearing capacity using the support component 1, while ensuring that the structural design and material selection of the thermal insulation structure 2 are not limited by the support component 1, thus not restricting the improvement of thermal insulation performance. Furthermore, by utilizing the adaptability of the support component 1, mutual damage between the thermal insulation structure 2 and the support component 1 under load can be avoided, thereby contributing to the simultaneous improvement of both load-bearing capacity and thermal insulation performance.

[0076] As shown in Figure 11, in the embodiments of this disclosure, the thermal insulation support structure 100 further includes a support plate structure 3, which is connected to a support member 10 of the support assembly 1. Furthermore, another support member 10 of the support assembly 1 is connected to a load-bearing plate structure 301, forming an thermal insulation space between the support plate structure 3 and the load-bearing plate structure 301. Thermal insulation structure 2 is formed by filling the thermal insulation space with thermal insulation material. The thermal insulation material is not specifically limited; it can be a thermal insulation material with no load-bearing capacity but good thermal insulation performance, such as expanded perlite, low-density PUF, polystyrene, aerogel, vacuum insulation board, etc. Alternatively, it can be a thermal insulation material that simultaneously possesses load-bearing capacity and thermal insulation capacity, such as high-density PUF, or a combination of different thermal insulation materials. Furthermore, the support plate structure 3 and the load-bearing plate structure 301 can be connected only by multiple support assemblies 1, or, as needed, the load transfer between the support plate structure 3 and the load-bearing plate structure 301 can be achieved through multiple support assemblies 1 of this disclosure and one or more support members of the prior art.

[0077] As shown in Figure 11, in the embodiments of this disclosure, the thermal insulation structure 2 includes multiple thermal insulation layers 21, which are stacked along the load transfer direction of the support component 1. In some embodiments of this disclosure, the thermal insulation layer 21 closest to the load application side has a higher resilience than other thermal insulation layers 21, and the thermal insulation performance of the thermal insulation layer 21 closest to the load bearing side is higher than other thermal insulation layers 21. That is, the thermal insulation layer 21 with the best resilience among the multiple thermal insulation layers 21 is bonded to the support plate structure 3, thereby making better use of the thermal insulation layer 21 with the highest resilience to adapt to compression or rebound, so as to avoid gaps between the support plate structure 3 and the thermal insulation structure 2; the thermal insulation layer 21 with the best thermal insulation performance among the multiple thermal insulation layers 21 is bonded to the bearing plate structure 301 to reduce the transfer of external heat to the interior. In other embodiments of this disclosure, along the load transfer direction, the resilience of the multiple thermal insulation layers 21 is progressively reduced, and the thermal insulation performance of the multiple thermal insulation layers 21 is progressively increased. In some embodiments of this disclosure, the resilience of the insulation layer 21 disposed closest to the load application side is higher than that of the other insulation layers 21, and the insulation properties and resilience of the other insulation layers 21 are not limited. For example, the resilience properties of the other insulation layers 21 can be set the same, and the insulation performance can also be set the same.

[0078] In one specific embodiment of this disclosure, there are two insulation layers 21, defined as a first insulation layer 211 and a second insulation layer 212. The first insulation layer 211 is disposed near the load application side, and the second insulation layer 212 is disposed near the load-bearing side. The resilience of the first insulation layer 211 is better than that of the second insulation layer 212, and the insulation performance of the second insulation layer 212 is better than that of the first insulation layer 211. In another specific embodiment, the first insulation layer 212 may be disposed near the load application side, and the second insulation layer 211 may be disposed near the load-bearing side, with the resilience of the first insulation layer 212 being better than that of the second insulation layer 211.

[0079] Referring to Figures 9 to 11, in the embodiments of this disclosure, one support member 10 is connected to the support plate structure 3 via a threaded connection structure 15, and / or another support member 10 is connected to a bearing plate structure 301 via another threaded connection structure 15, allowing the position of the support plate structure 3 to be adjusted by rotating any support member 10. Optionally, the number of support components 1 is at least three, and the at least three support components 1 can cooperate to adjust the angle of inclination of the support plate structure 3 relative to the vertical direction of the load transmission direction. For example, when the load transmission direction is vertical, the levelness of the support plate structure 3 can be adjusted by rotating and adjusting the first support member 11 and / or the second support member 12 of the at least three support components 1; when the load transmission direction is horizontal, the verticality of the support plate structure 3 can be adjusted by rotating and adjusting the first support member 11 and / or the second support member 12 of the at least three support components 1. This helps to reduce construction difficulty, speed up the construction period, and ensure that the support plate structure 3 is subjected to uniform force.

[0080] Specifically, the support plate structure 3 includes multiple support plates 31 that are spliced ​​together, and a support member 10 (i.e., the first support member 11) of the support assembly 1 can connect one or more support plates 31. Specifically, the support member 10 can be positioned below the splice of multiple plates to connect multiple support plates 31. Similarly, the load-bearing plate structure 301 includes multiple load-bearing plates 3011 that are spliced ​​together, and another support member 10 (i.e., the second support member 12) of the support assembly 1 can connect one or more load-bearing plates 3011. Among them, the load-bearing plates 3011 include, but are not limited to, concrete slabs made of cast concrete.

[0082] As shown in Figures 12 and 13, this disclosure also provides a membrane container, including a heat-insulating support structure 100. The membrane container also includes an inner membrane tank 200 and an outer membrane tank 300, with the heat-insulating support structure 100 disposed between the inner membrane tank 200 and the outer membrane tank 300. The heat-insulating support structure 100 in this embodiment is the same as the heat-insulating support structure 100 in Embodiment 1 in terms of specific structure, working principle, and beneficial effects, and will not be described again here.

[0083] Specifically, the inner membrane tank 200 is attached and supported on the support plate structure 3 of the thermal insulation support structure 100, and the second support member 12 of the support component 1 of the thermal insulation support structure 100 is connected to the outer tank 300. The inner membrane tank 200 is composed of multiple membrane plates 201 spliced ​​together.

Those skilled in the art can make various modifications or variations to the embodiments of this disclosure based on the content disclosed in the application documents without departing from the spirit and scope of this disclosure.
