Description

Technical Field

[0001] The present application relates to the technical field of storage tank containers, and in particular to a membrane storage tank and a leveling component and an installation method thereof. Background Art

[0002] During the storage and transportation of liquefied natural gas (LNG), the thermal insulation performance of LNG storage tanks is crucial. Since LNG needs to be stored at extremely low temperatures (about -162°C), any heat infiltration may cause the LNG to vaporize, resulting in increased pressure and safety risks. Therefore, LNG storage tanks usually adopt a double-layer structure, with an inner tank for storing LNG and an outer tank as a protective layer, and an insulation module installed between the two to maintain a low-temperature environment.

[0003] The installation quality of the insulation module directly affects the thermal insulation effect and safety of the tank. However, whether it is a ship LNG tank or a land LNG tank, the installation base (such as the metal wall of the cabin or the inner wall of the concrete outer tank) often has the problem of uneven surface. In ship applications, the metal bulkhead may become uneven due to welding deformation, processing errors or long-term stress; in land tanks, the concrete pouring process may cause roughness or local protrusions due to formwork deformation, shrinkage or construction errors.

[0004] This unevenness will cause the insulation module to not fit tightly against the base surface, resulting in gaps, reducing the insulation effect, and even causing the module to break or fall off due to local stress concentration. In addition, during ship transportation, if the insulation module is not installed firmly, it may also shift due to the shaking or vibration of the ship, further exacerbating the decline in insulation performance and safety risks.

[0005] At present, the traditional method of installing thermal insulation modules usually relies on manual adjustment or gasket filling, but this method is inefficient, has poor precision, and is difficult to adapt to the irregular shapes of different base surfaces. Therefore, there is an urgent need for a membrane storage tank and its leveling assembly and installation method to ensure that the thermal insulation module can be installed firmly and tightly on various base surfaces, thereby improving the safety and thermal insulation performance of LNG storage tanks. Summary of the invention

[0006] The present application provides a membrane storage tank and a leveling component and an installation method thereof, so as to solve the current problems of uneven concrete and low installation efficiency.

[0007] In the first aspect, the present application provides a leveling assembly for a membrane storage tank, comprising: at least two first connecting structures embedded in a mounting layer; a bracket body, the bracket body having a first surface facing the mounting layer and a second surface away from the mounting layer, the second surface facing the insulation module; a plurality of second connecting structures on the first surface, the number of the second connecting structures being at least greater than the number of the first connecting structures, and the second connecting structures being capable of being connected in coordination with the first connecting structures; when the first connecting structure and the second connecting structure are connected, the relative distance between the first connecting structure and the second connecting structure can be adjusted.

[0008] Through the above scheme, the precise connection between the bracket body and the mounting layer is achieved through the first connection structure embedded in the mounting layer and the second connection structure on the bracket body. The number of the second connection structure is more than the first connection structure, which can provide more connection points, thereby improving the installation accuracy of the storage tank. The relative distance between the first connection structure and the second connection structure can be adjusted, which enables the leveling component to adapt to the inner wall surfaces of various flatnesses, and can be fine-tuned according to actual conditions during the construction process to ensure the flatness and stability of the bracket body. By embedding the connection structure inside the mounting layer, the connection strength between the storage tank and the wall is enhanced, avoiding tilting or damage after the insulation module is fixed due to external force or uneven settlement. The design of the leveling component simplifies the construction process, reduces the complex leveling operations in traditional construction, reduces the construction difficulty and time cost, and can achieve a stable and tight installation, thereby improving the safety and insulation performance of the LNG storage tank.

[0009] In a possible design, the area of ​​the second surface is smaller than the area of ​​the installation surface of the thermal insulation module, and the first surface is parallel to the second surface.

[0010] Through the above scheme, the area of ​​the second surface is smaller than the area of ​​the insulation module installation surface, which means that the size of the bracket body is relatively small, which can save materials and installation space. This compact design makes the entire leveling assembly lighter, easier to transport and install, and reduces the difficulty and cost of construction. Since the first surface is parallel to the second surface and the second surface area is small, the leveling assembly can be more conveniently adjusted in the horizontal or vertical direction during the installation process to ensure the tight connection between the insulation module and the storage tank. The area of ​​the second surface of the bracket body is smaller than the area of ​​the insulation module installation surface, but through the cooperation of multiple second connection structures with the first connection structure, the force can be evenly distributed to the installation layer to avoid local stress concentration, thereby enhancing the stability of the entire tank system. This design makes the installation of the bracket body simpler, and the construction personnel can quickly complete the connection between the bracket and the installation layer, while reducing the error caused by improper installation. Since the first surface is parallel to the second surface and the second surface area is small, the leveling assembly can be quickly calibrated in the horizontal or vertical direction by simple tools or manual adjustment during the installation process, thereby improving construction efficiency.

[0011] In a possible design, the bracket body is composed of crisscross reinforcing ribs to form a plurality of intersections, and a second connection structure is formed at each intersection.

[0012] Through the above scheme, the criss-cross reinforcement rib design can effectively disperse and bear the weight of the storage tank and the insulation module, improve the bearing capacity of the bracket, and the second connection structure at the intersection provides multiple connection points, which can be flexibly coordinated with the pre-buried first connection structure to ensure that the storage tank can be accurately leveled during installation. The criss-cross reinforcement rib structure reduces material waste and manufacturing costs while ensuring strength. The cross structure of the reinforcement ribs can effectively resist external forces, such as earthquake loads or wind, and improve the overall seismic performance of the storage tank. The bracket body design composed of criss-cross reinforcement ribs not only improves the structural stability and connection accuracy of the tank leveling assembly, but also optimizes material usage and construction efficiency, and has high practicality and economy.

[0013] In a possible design, the second connection structure is a threaded hole; the first connection structure includes an embedded mounting member and a connection bolt fixed on the embedded mounting member.

[0014] Through the above scheme, the threaded holes are directly processed at the intersection of the bracket body, which can be matched with the connecting bolts. The embedded mounting parts are pre-embedded inside the mounting layer to ensure close connection with the concrete. The connecting bolts are fixed on the embedded mounting parts and are used to match and connect with the threaded holes of the bracket body. Through the cooperation of the bolts and the threaded holes, high-precision connection and fine-tuning can be achieved. During the installation process, the position of the bracket body can be adjusted as needed to ensure the horizontality and verticality of the tank. The threaded connection has high strength and stability, can effectively bear the weight of the tank and the insulation module, and reduce deformation caused by external force or uneven settlement.

[0015] In one possible design, the connecting bolt is a universal joint bolt.

[0016] Through the above scheme, the universal joint bolt can adapt to the angular offset between the axes, ensuring the stability and reliability of the connection even if there is a certain angular deviation during the installation process. This is especially important for the installation of membrane tanks, because there may be slight angular errors between the tank and the bracket, and the universal joint bolt can effectively compensate for these errors.

[0017] In a possible design, at least one end of the connecting bolt is provided with a spherical washer.

[0018] Through the above scheme, the spherical washer can create a precise parallel contact surface between the bolt head and the nut, and automatically adjust to compensate for the angular deviation between the planes. This feature is particularly suitable for the installation scenario of membrane tanks, because there may be slight angular errors between the tank and the bracket, and the spherical washer can effectively compensate for these errors and prevent the bolts from bending. The spherical washer can evenly distribute the clamping force of the bolt over the entire contact surface, thereby reducing local stress concentration. This not only improves the reliability of the connection, but also reduces the fatigue of the bolts caused by uneven force. The design of the spherical washer can prevent the bolts from bending, thereby reducing the possibility of bolt loosening. In this embodiment, the spherical washer is made of high-grade alloy steel and is specially surface treated to provide better protection in humid or corrosive environments.

[0019] In one possible design, the second connection structure is a snap-on interface; the first connection structure includes a pre-embedded snap-on base and a snap-on connector; the pre-embedded snap-on base includes a spherical or universal joint structure that can rotate freely within a certain angle range; the snap-on interface is connected to the pre-embedded snap-on base via a spherical snap or a universal joint snap.

[0020] Through the above scheme, the snap-on interface is designed to quickly connect and separate with the snap-on connector, and the operation is simple. The embedded snap-on base is embedded in the installation layer, and adopts a spherical or universal joint structure, which can rotate freely within a certain angle range and provide angle compensation capability. Snap-on connector: fixed on the embedded snap-on base, used to cooperate with the second connection structure (snap-on interface) to achieve quick connection. The snap-on interface and the embedded snap-on base are connected by a spherical snap or a universal joint snap. This connection method allows angle adjustment during installation to ensure precise alignment between the tank and the bracket. The embedded snap-on base with a spherical or universal joint structure can rotate freely within a certain angle range to adapt to the angle deviation that may occur during the installation process, ensuring precise alignment between the tank and the bracket. This design combines the snap-on interface with the embedded snap-on base with a spherical or universal joint structure to achieve flexibility in angle adjustment, convenience in rapid installation and disassembly, reliability in structural strength and stability, and convenience in maintenance and replacement. It is used for the installation of membrane tank systems, which can significantly improve the overall performance and construction efficiency of the system.

[0021] In a possible design, a plurality of snap positions are designed inside the snap interface or on the snap connector, and the snap interface and the snap connector can be fixed in different gears to achieve height or angle adjustment.

[0022] Through the above solution, multiple snap-in positions are designed inside the snap-in interface to achieve adjustment at different heights or angles. Combined with the embedded snap-in base of the spherical or universal joint structure, the overall performance and construction efficiency of the system can be significantly improved.

[0023] In a possible design, an end portion of the first connection structure can pass through the bracket body and form a fixed connection with the thermal insulation module.

[0024] Through the above solution, the end of the first connecting structure is designed to be able to pass through the bracket body and form a fixed connection with the insulation module, which can ensure the stability of the insulation module.

[0025] In a possible design, it further includes at least one gasket, which is sleeved on the first connecting structure and / or the second connecting structure; the gasket is arranged between the bracket body and the mounting layer and / or between the insulation modules.

[0026] Through the above solution, the gasket can be used to adjust the gap between the first connection structure and the second connection structure to ensure the tightness of the connection and prevent loosening. It can make the force of the connection structure more uniform, reduce local stress concentration, and improve the stability of the connection; the gasket is arranged between the bracket body and the mounting layer and / or between the insulation modules to better achieve leveling.

[0027] In a possible design, a resin mastic layer is also included, and the resin mastic layer wraps the bracket body.

[0028] Through the above solution, the resin mastic layer can tightly bond the various parts of the bracket body together to form a whole, thereby improving the structural strength and stability of the bracket. The wrapping of the resin mastic layer can reduce the loosening and deformation of the bracket body caused by vibration or external force during use. The resin mastic layer can fill the tiny gaps and unevenness on the surface of the bracket body to form a smooth surface, providing a better foundation for the installation of the insulation module.

[0029] In a second aspect, the present application provides a membrane storage tank, comprising a mounting layer, an insulation module, and a leveling assembly of any of the above items, wherein the leveling assembly is fixed to the mounting layer, and the insulation module is fixed to the leveling assembly.

[0030] The beneficial effects of the membrane storage tank provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation method of the first aspect, and will not be repeated here.

[0031] In a third aspect, the present application provides a method for installing a membrane storage tank, comprising the steps of: installing a first connecting structure on a mounting layer; providing any of the above-mentioned leveling components, connecting a second connecting structure and a first connecting structure, and adjusting a distance between the second connecting structure and the first connecting structure according to a surface condition of the mounting layer so that surfaces between bracket bodies are parallel; covering a thermal insulation module on the bracket body, and fixing the thermal insulation module via the first connecting structure.

[0032] In the installation method of the membrane storage tank provided in the second aspect and each possible design of the second aspect, the bracket body is installed according to the surface condition of the installation layer, and the distance between the second connection structure and the first connection structure is adjusted so that the bracket body meets the flatness requirement for the installation of the thermal insulation module. The installation bracket body can be quickly leveled, so that the thermal insulation module can be quickly installed, thereby improving the installation efficiency of the membrane storage tank.

[0033] In a possible design, before covering the thermal insulation module on the support body, the method further includes the step of pouring resin mastic inside the support body to form a resin mastic layer.

[0034] Through the above scheme, resin putty is poured inside the bracket body, so that the bracket body is buried inside the resin putty layer. The resin putty layer can further play a leveling and stabilizing effect, and also provide a better attachment basis for the insulation module, thereby enhancing the bonding force between the insulation module and the bracket body.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0053] From the background technology, it can be known that in the current membrane storage tank manufacturing process, the stability and insulation effect of the insulation module 300 are very important to the quality of the storage tank. However, the installation of the insulation module 300 usually requires a flat inner wall surface, otherwise it will lead to installation difficulties, poor insulation effect, and even falling off.

[0054] In view of this, the embodiment of the present application provides a membrane storage tank and its leveling component and installation method. In the leveling component of the membrane storage tank, the first connection structure 120 pre-buried in the installation layer 100 and the second connection structure 210 on the bracket body 200 are used to achieve accurate connection between the bracket body 200 and the installation layer 100. The number of the second connection structure 210 is greater than the first connection structure 120, which can provide more connection points, thereby improving the installation accuracy of the storage tank. The second connection structure 210 can be selected according to the actual situation of the concrete wall to connect with the corresponding first connection structure 120, so as to achieve a better leveling effect. The relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted, so that the leveling component can adapt to the inner wall surface of various flatness, and can be fine-tuned according to the actual situation during the construction process to ensure the flatness and stability of the bracket body 200. The design of the leveling component simplifies the construction process, reduces the complex leveling operation in traditional construction, reduces the construction difficulty and time cost, and improves the manufacturing efficiency.

[0055] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0056] Figure 1 This is a schematic diagram of the thermal insulation module 300 provided in this embodiment installed on the inner wall. Figure 1 The leveling assembly of the membrane storage tank in this embodiment includes: at least two first connection structures 120 embedded in the mounting layer 100 and a bracket body 200. The bracket body 200 has a first surface facing the mounting layer 100 and a second surface facing away from the mounting layer 100, and the second surface faces the insulation module 300; the first surface has a plurality of second connection structures 210, the number of the second connection structures 210 is at least greater than the first connection structure 120, and the second connection structure 210 can be connected with the first connection structure 120; when the first connection structure 120 and the second connection structure 210 are connected, the relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted.

[0057] The installation layer can be the concrete layer of a land storage tank or the metal wall of a LNG ship's cabin.

[0058] The support body 200 is fixed on the installation layer 100 , and by adjusting the relative positions of the support body 200 and the installation layer 100 , the insulation module 300 has a flat surface for attachment and fixing.

[0059] In some embodiments, the outline of the bracket body 200 can be any shape, for example, it can be square or circular. It can be understood that the shape of the first surface and / or the second surface is square or circular.

[0060] The insulation module 300 is made of insulation materials such as polystyrene foam, enhanced polyurethane foam, and plywood on both sides of the insulation materials, and the structure is similar to a "sandwich" structure. The plywood can play the role of connection, fixing, and supporting, thereby improving the strength of the insulation module 300 and preventing it from breaking.

[0061] Figure 2 This is a schematic diagram of fixing the first connection structure 120 on the mounting layer 100 provided in this embodiment. Figure 2 The number and position of the first connection structures 120 should be flexibly determined according to the condition of the concrete inner wall, and can be set to 2, 3 or 4. The more the number of first connection structures 120, the tighter the connection between the bracket body 200 and the mounting layer 100. However, too many first connection structures 120 will affect the thermal insulation performance of the membrane storage tank and reduce the subsequent installation speed. Therefore, in this embodiment, the number of first connection structures 120 does not exceed 4.

[0062] Through the above scheme, the first connection structure 120 embedded in the installation layer 100 and the second connection structure 210 on the bracket body 200 realize the precise connection between the bracket body 200 and the installation layer 100. The number of the second connection structure 210 is greater than the first connection structure 120, which can provide more connection points, thereby improving the installation accuracy of the storage tank. The relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted, which enables the leveling component to adapt to the inner wall surface of various flatnesses, and can be fine-tuned according to actual conditions during the construction process to ensure the flatness and stability of the bracket body 200. By embedding the connection structure inside the installation layer 100, the connection strength between the storage tank and the wall is enhanced, and the tilting or damage of the fixed insulation module 300 due to external force or uneven settlement is avoided. The design of the leveling component simplifies the construction process, reduces the complex leveling operation in traditional construction, reduces the construction difficulty and time cost, and can achieve a stable and tight installation, thereby improving the safety and insulation performance of the LNG storage tank.

[0063] In this embodiment, the area of ​​the second surface is smaller than the area of ​​the installation surface of the insulation module 300, which means that the size of the bracket body 200 is relatively small, which can save materials and installation space. This compact design makes the entire leveling assembly lighter, easier to transport and install, and reduces construction difficulty and cost.

[0064] In this embodiment, the first surface is parallel to the second surface, that is, the bracket body 200 is a flat structure. In this way, the bracket body 200 can be adjusted in the horizontal or vertical direction by adjusting the relative distance between the first connecting structure 120 and the second connecting structure 210, so as to ensure the tight connection of the insulation module 300.

[0065] By cooperating with the first connection structure 120, the force can be evenly distributed to the installation layer 100 to avoid local stress concentration, thereby enhancing the stability of the entire tank system. This design makes the installation of the bracket body 200 easier, and the construction personnel can quickly complete the connection between the bracket and the installation layer 100, while reducing the error caused by improper installation. Since the first surface is parallel to the second surface and the second surface is smaller in area, the leveling assembly can be quickly calibrated in the horizontal or vertical direction through simple tools or manual adjustment during the installation process, thereby improving construction efficiency.

[0066] Figure 3 It is a schematic structural diagram of a bracket body 200 provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the structure of the support body 200 provided in another embodiment of the present application. Figure 3 and Figure 4 The bracket body 200 is composed of crisscross reinforcing ribs to form a plurality of intersections, and a second connection structure 210 is formed at each intersection.

[0067] like Figure 3 The crisscross reinforcement bars can be square bars or Figure 4 The crisscross reinforcement bars are round bars. The diameter of the round bar reinforcement bar or the width of the square bar reinforcement bar shall not exceed 1 cm.

[0068] Through the above scheme, the criss-cross reinforcement rib design can effectively disperse and bear the weight of the storage tank and the insulation module 300, improve the bearing capacity of the bracket, and the second connection structure 210 at the intersection provides multiple connection points, which can be flexibly matched with the pre-buried first connection structure 120 to ensure that the storage tank can be accurately leveled during installation. The criss-cross reinforcement rib structure reduces material waste and manufacturing costs while ensuring strength. The cross structure of the reinforcement ribs can effectively resist external forces, such as earthquake loads or wind, and improve the overall seismic performance of the storage tank. The design of the bracket body 200 composed of criss-cross reinforcement ribs not only improves the structural stability and connection accuracy of the tank leveling assembly, but also optimizes the use of materials and construction efficiency, and has high practicality and economy. In addition, since the first surface and the second surface are parallel, the second connection structure 210 is formed inside each intersection position. When the insulation module 300 directly contacts the bracket body 200, the insulation module 300 has a relatively flat attachment surface, which can improve the installation stability of the insulation module 300.

[0069] The relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted by providing a spacer 130 and different connection structures.

[0070] Figure 5It is a schematic diagram that the gaskets are respectively arranged between the bracket body and the mounting layer and between the bracket body and the insulation module. Figure 6 This is a schematic diagram showing that the gasket is only set between the bracket body and the mounting layer. Figure 5 and Figure 6 In this embodiment, at least one gasket 130 is included, and the gasket 130 is sleeved on the first connection structure 120 and / or the second connection structure 210; the gasket 130 is arranged between the bracket body 200 and the mounting layer 100 and / or between the insulation modules 300.

[0071] The material of the gasket 130 can be a non-metallic gasket, such as rubber, polytetrafluoroethylene, etc. The non-metallic gasket has good corrosion resistance, can protect the connection structure from chemical erosion, and prolong the service life.

[0072] Through the above solution, the gasket 130 can be used to adjust or assist in adjusting the distance between the first connection structure 120 and the second connection structure 210, that is, it can be used to adjust the gap between the first connection structure 120 and the second connection structure 210, and can ensure the tightness of the connection and prevent loosening. It can make the force of the connection structure more uniform, reduce local stress concentration, and improve the stability of the connection. When needed, the gasket 130 is simple and convenient to use, and construction personnel can quickly complete the installation without complicated tools or operations.

[0073] In some embodiments, if the bracket body 200 is fixed on the installation layer 100 for leveling, and then the insulation module 300 is installed, it is found that the bracket body 200 does not meet the surface flatness requirements for the installation of the insulation module 300, a gasket 130 (such as Figure 5 As shown in the figure, the tank is further leveled to meet the installation requirements of the insulation module 300. This can improve the installation effect of the storage tank and ensure the stability of the storage tank.

[0074] In some embodiments, a plurality of second connection structures 210 are correspondingly designed on the main structure.

[0075] In this embodiment, the second connection structure 210 can be a threaded hole. The threaded hole is directly processed at the intersection of the bracket body 200, which can be matched with the connecting bolt, and can reasonably utilize the space area, so that the number of second connection structures 210 is as large as possible, so that the second connection structure 210 and the first connection structure 120 can be selected to be connected at a suitable position according to the surface conditions of the inner wall of the concrete. Since the number of the second connection structures 210 is sufficient, the accuracy requirements for the pre-embedded installation of the first connection structure 120 are reduced (any first connection structure 120 can find a suitable second connection structure 210 for corresponding connection), so that the installation position of the first connection structure 120 is more flexible, which can reduce the calibration time, thereby improving the installation efficiency.

[0076] In some embodiments, the first connection structure 120 includes an embedded installation component 110 and a connection bolt fixed to the embedded installation component 110 .

[0077] Through the above scheme, the embedded mounting part 110 can be pre-buried in the mounting layer 100 by anchoring to ensure close connection with the concrete. The connecting bolt is fixed on the embedded mounting part 110, and is used to cooperate with the threaded hole of the bracket body 200. Through the cooperation of the bolt and the threaded hole, high-precision connection and fine-tuning can be achieved. During the installation process, the position of the bracket body 200 can be adjusted as needed to ensure the horizontality and verticality of the storage tank. The threaded connection has high strength and stability, can effectively bear the weight of the storage tank and the insulation module 300, and reduce deformation caused by external force or uneven settlement.

[0078] In this embodiment, the connecting bolt is a universal joint bolt.

[0079] Through the above scheme, the universal joint bolt can adapt to the angular offset between the axes, ensuring the stability and reliability of the connection even if there is a certain angular deviation during the installation process. This is especially important for the installation of membrane tanks, because there may be slight angular errors between the tank and the bracket, and the universal joint bolt can effectively compensate for these errors.

[0080] In this embodiment, a spherical washer is provided at at least one end of the connecting bolt.

[0081] Through the above scheme, the spherical washer can create a precise parallel contact surface between the bolt head and the nut, and automatically adjust to compensate for the angular deviation between the planes. This feature is particularly suitable for the installation scenario of membrane tanks, because there may be slight angular errors between the tank and the bracket, and the spherical washer can effectively compensate for these errors and prevent the bolts from bending. The spherical washer can evenly distribute the clamping force of the bolt over the entire contact surface, thereby reducing local stress concentration. This not only improves the reliability of the connection, but also reduces the fatigue of the bolts caused by uneven force. The design of the spherical washer can prevent the bolts from bending, thereby reducing the possibility of bolt loosening. In this embodiment, the spherical washer is made of high-grade alloy steel and is specially surface treated to provide better protection in humid or corrosive environments.

[0082] The process of installing the bracket body 200 through the above-mentioned embedded mounting frame can be as follows: first, place the bracket body 200 at the corresponding position, then select the threaded holes and connecting bolts at the appropriate positions for pre-connection, and then adjust the distance between the threaded holes and the universal joint bolts according to the needs of flatness. When adjusting the distance between the threaded holes and the connecting bolts, the angle of the universal joint bolts can be appropriately adjusted according to the situation, thereby ensuring the flatness of the bracket body 200 through fine-tuning, and finally fix the universal joint bolts to ensure the stability of the installation bracket.

[0083] In this embodiment, the second connection structure 210 is a snap-on interface; the first connection structure 120 includes a pre-embedded snap-on base and a snap-on connector; the pre-embedded snap-on base includes a spherical or universal joint structure, which can rotate freely within a certain angle range; the snap-on interface is connected to the pre-embedded snap-on base via a spherical snap or a universal joint snap.

[0084] Through the above scheme, the buckle interface is designed to quickly connect and separate with the buckle connector, and the operation is simple. The embedded buckle base is embedded in the installation layer 100, and adopts a spherical or universal joint structure, which can rotate freely within a certain angle range and provide angle compensation capability. Buckle connector: fixed on the embedded buckle base, used to cooperate with the second connection structure 210 (snap-up interface) to achieve quick connection. The buckle interface and the embedded buckle base are connected by a spherical buckle or a universal joint buckle. This connection method allows angle adjustment during installation to ensure accurate alignment between the tank and the bracket. The embedded buckle base of the spherical or universal joint structure can rotate freely within a certain angle range to adapt to the angle deviation that may occur during the installation process, and ensure accurate alignment between the tank and the bracket. This design combines the buckle interface with the embedded buckle base of the spherical or universal joint structure to achieve flexibility in angle adjustment, convenience of rapid installation and disassembly, reliability of structural strength and stability, and convenience of maintenance and replacement. It is used for the installation of the membrane tank system, which can significantly improve the overall performance and construction efficiency of the system.

[0085] In this embodiment, a plurality of snap-in positions are designed inside the snap-in interface or on the snap-in connector, and the snap-in interface and the snap-in connector can achieve fixation at different gears and achieve adjustment of height or angle.

[0086] The snap-on interface and the snap-on connector are locked when used to fix any gear position and will not rotate or move any further.

[0087] Through the above solution, multiple snap-in positions are designed inside the snap-in interface to achieve adjustment at different heights or angles. Combined with the embedded snap-in base of the spherical or universal joint structure, the overall performance and construction efficiency of the system can be significantly improved.

[0088] The process of installing the bracket body 200 through the above-mentioned embedded mounting frame can be as follows: first, place the bracket body 200 at the corresponding position, then select the snap interface and the snap connector at the appropriate position for pre-connection, and then adjust the distance between the snap interface and the snap connector according to the flatness requirements, or you can also adjust the angle of the spherical snap or the universal joint snap to achieve fine-tuning. When adjusting the distance between the snap interface and the snap connector, you can appropriately adjust the snap position inside the snap interface according to the situation to ensure the flatness of the bracket body 200 and ensure the stability of the installed bracket.

[0089] Please continue to refer to Figure 5 and Figure 6 In this embodiment, the end of the first connection structure 120 can pass through the bracket body 200 and form a fixed connection with the insulation module 300.

[0090] Through the above solution, the end of the first connection structure 120 is designed to be able to pass through the bracket body 200 and form a fixed connection with the insulation module 300, which can ensure the stability of the fixation of the insulation module 300.

[0092] After the bracket body 200 is installed, a resin mastic layer 400 may be formed inside and on the surface of the bracket body 200 by pouring, spraying or brushing.

[0093] Through the above scheme, the resin cement layer 400 can tightly bond the various parts of the bracket body 200 together to form a whole, thereby improving the structural strength and stability of the bracket. The wrapping of the resin cement layer 400 can reduce the loosening and deformation of the bracket body 200 caused by vibration or external force during use. The resin cement layer 400 can fill the small gaps and unevenness on the surface of the bracket body 200 to form a smooth surface, providing a better foundation for the installation of the insulation module 300 and making the installation of the insulation module 300 more stable.

[0094] Based on the above embodiments, the present application also provides a membrane storage tank, including a mounting layer 100, an insulation module 300 and a leveling assembly of any of the above items, wherein the leveling assembly is fixed on the mounting layer 100, and the insulation module 300 is fixed on the leveling assembly.

The installation bracket body 200 can be quickly leveled, so that the insulation module 300 can be quickly installed, thereby improving the installation efficiency of the membrane storage tank.

[0098] In a possible design, before covering the insulation module 300 on the support body 200 , a step is further included: pouring resin mastic in the support body 200 to form a resin mastic layer 400 .

[0099] Through the above scheme, resin putty is poured into the bracket body 200, so that the bracket body 200 is buried inside the resin putty layer 400. The resin putty layer 400 can further play a leveling and stabilizing effect, and also provide a better attachment basis for the insulation module 300, thereby enhancing the bonding force between the insulation module 300 and the bracket body 200.
