Description

Technical Field

[0001] This utility model relates to the field of concrete water tank technology, specifically to a support frame for the interior of a prefabricated concrete water tank and a water tank using the same. Background Technology

[0002] Water tanks have applications in various fields, such as fire protection systems, industrial systems, agricultural systems, and other aspects of daily life. Concrete water tanks, constructed primarily of concrete (usually reinforced concrete), are water storage or treatment structures widely used in municipal, industrial, and construction sectors. However, traditional cast-in-place concrete water tanks present several challenges. These include multiple overlapping work areas on construction sites, the use of various trades and equipment, and the tanks' susceptibility to cracking and pit collapse. These issues lead to extensive formwork work, long construction periods, difficult on-site management, and potential safety hazards. As a result, traditional cast-in-place concrete water tanks can no longer meet the demands of today's rapidly evolving market. Therefore, prefabricated concrete water tanks, which offer higher construction efficiency, have become increasingly popular.

[0003] During the construction of prefabricated concrete water tanks, several prefabricated tank side panels are connected by assemblies to form a tank frame. To ensure the overall structural strength of the tank, a support frame is needed inside the tank frame to connect the tank side panels into a single unit, thereby improving the overall structural strength of the prefabricated concrete water tank. Currently, most support frames used inside prefabricated concrete water tanks are metal support frames, which are assembled from components such as columns, tie rods, connecting fasteners, bolts, and nuts. The problem with metal support frames is that metal components are prone to oxidation and corrosion (rust) when immersed in water or in a humid environment for extended periods, especially at joints where loosening or breakage is likely. This necessitates frequent and regular inspection and reinforcement of the support frame, and even then, it is difficult to guarantee that the support frame will have the same lifespan as the tank frame. Therefore, this utility model proposes a support frame for the interior of prefabricated concrete water tanks and a water tank using the same design, aiming to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the deficiencies in the existing technology and provide a support frame for the interior of a prefabricated concrete water tank and a water tank using the same. Several horizontal and vertical support frames are sequentially assembled from several prefabricated frame units connected by a second tensioning mechanism. Several prefabricated frame units located circumferentially on the outer periphery of the support frame are fixedly connected to the corresponding side panels of the water tank via a first tensioning mechanism. Furthermore, every four adjacent prefabricated frame units are fixedly connected together by concrete poured at the cross joints, ensuring that the support frame and the outer periphery of the water tank side panels form a concrete structure with good overall consistency, high structural strength, good stability, and high compressive strength. This ensures the quality of the prefabricated concrete water tank constructed using the support frame of this invention. It features strong tensile and shear strength, as well as good buoyancy resistance. The support frame of this utility model avoids exposing metal components such as steel bars and mounting bolts in water or humid environments. It has good corrosion resistance, the same lifespan as the side plate of the pool, and does not require frequent periodic inspection and maintenance, which helps to save on labor maintenance costs. The precast frame unit of the concrete precast component ensures that the support frame of this utility model has high compressive strength, thereby ensuring that the prefabricated concrete pool assembled using this support frame can effectively bear the water load inside the pool, the self-weight of the structure, and external additional loads (such as the weight of vehicles, equipment, etc.). It is especially suitable for supporting the top plate of the pool, reducing the displacement or cracks of the side plate of the pool caused by the load, and ensuring the overall structural safety of the prefabricated concrete pool.

[0005] One of the objectives of this utility model is to design a support frame for the interior of a prefabricated concrete water tank, comprising several corresponding parallel and spaced transverse support frames and several corresponding parallel and spaced longitudinal support frames, wherein the transverse and longitudinal support frames are vertically and intersectingly fixed together, and the transverse and longitudinal support frames are all formed by sequentially splicing together several prefabricated frame units. Two prefabricated frame units that are connected to each other are fixedly connected together by a tensioning connection mechanism two. Every four adjacent prefabricated frame units are fixedly connected together by concrete poured at the cross joint. Several prefabricated frame units located circumferentially on the outer periphery of the support frame are respectively fixedly connected to the corresponding water tank side plates by a tensioning connection mechanism one.

[0006] This utility model discloses a support frame for the interior of a prefabricated concrete water tank. Several horizontal and vertical support frames are sequentially assembled from prefabricated frame units connected by a second tensioning mechanism. Several prefabricated frame units located circumferentially on the outer periphery of the support frame are fixedly connected to the corresponding side panels of the water tank via a first tensioning mechanism. Furthermore, every four adjacent prefabricated frame units are fixedly connected together by concrete poured at the cross joints. This ensures that the support frame and the outer periphery of the water tank side panels form a concrete structure with good overall consistency, high structural strength, good stability, and high compressive strength. Therefore, the prefabricated concrete water tank constructed using this utility model's support frame possesses strong tensile and shear resistance, and high compressive strength. The support frame of this invention features excellent buoyancy and avoids exposing metal components such as reinforcing bars and mounting bolts to water or humid environments. It exhibits good corrosion resistance, has the same lifespan as the side panels of the pool, and does not require frequent periodic inspections and maintenance, thus saving on labor costs. The precast frame unit of the concrete precast component ensures that the support frame of this invention has high compressive strength, thereby ensuring that the prefabricated concrete pool assembled using this support frame can effectively withstand the water load inside the pool, the structural self-weight, and external additional loads (such as the weight of vehicles and equipment). It is particularly suitable for supporting the top slab of the pool, reducing displacement or cracks in the side panels caused by loads, and ensuring the overall structural safety of the prefabricated concrete pool.

[0007] A preferred technical solution is that a reinforcing cage is pre-embedded inside the prefabricated frame unit, and several upwardly extending reinforcing bar ends are spaced at intervals along the length of the top of the prefabricated frame unit. The height of the prefabricated frame unit is equal to that of the side plate of the water tank. When assembling and building a prefabricated concrete water tank using the support frame of this utility model, the reinforcing bar ends at the top of the prefabricated frame unit extend into the joint between two adjacent water tank top plates and are welded and fixed together with the reinforcing bar ends exposed on the outer periphery of the water tank top plate. Then, concrete is poured at the joint to ensure the convenience and firmness of the fixed connection between the support frame and the water tank top plate.

[0008] A further preferred technical solution is that each of the prefabricated frame units constituting the horizontal support frame or the vertical support frame includes two frame unit 1 and several frame unit 2, wherein the several frame unit 2 are sequentially connected and spliced ​​on the inner side of the horizontal support frame or the vertical support frame, and the two frame unit 1 are correspondingly spliced ​​on the two ends of the horizontal support frame or the vertical support frame. Both the frame unit 1 and the frame unit 2 are "n"-shaped structures with downward openings. Both include a horizontal top arm at the top and longitudinal support arms at the two ends of the lower side of the horizontal top arm. The longitudinal support arms are provided with several longitudinal waist holes at longitudinal intervals. The two prefabricated frame units that are connected to each other are fixedly connected together by bolt assemblies 2 that pass through the two longitudinal support arms and correspond to the two longitudinal waist holes. The two corresponding longitudinal waist holes and the bolt assemblies 2 that pass through them constitute the tensioning connection mechanism 2.

[0009] The frame unit 1, facing the corresponding side panel of the pool, has a longitudinal support arm that is fixedly connected to the two corresponding side panels via a bolt assembly 1 inside the side panel connecting assembly at the joint between the longitudinal waist hole and the two corresponding side panels. The longitudinal waist hole, the side panel connecting assembly, and the bolt assembly 1 inside both constitute the tensioning connection mechanism 1. The prefabricated frame unit, tensioning connection mechanism 1, and tensioning connection mechanism 2 have a clever and reasonable structural design. Furthermore, the prefabricated frame unit has longitudinal waist holes on its two longitudinal support arms, so that when four adjacent prefabricated frame units are connected, the bolt assembly 2 passing through one set of opposite longitudinal support arms avoids contact with the bolt assembly 2 passing through another set of opposite longitudinal support arms, thus ensuring the smooth assembly of the support frame of this utility model.

[0010] A further preferred technical solution is that the end of the longitudinal waist hole facing the inner side of frame unit one or frame unit two is set as a countersunk groove structure. When the two prefabricated frame units are fixedly connected by bolt assemblies two passing through the corresponding longitudinal waist holes on the two opposing longitudinal support arms, the nut end or bolt end of bolt assembly two is located inside the countersunk groove. Similarly, when the longitudinal support leg on frame unit one is connected to the corresponding water tank side plate through bolt assembly one, the nut end or bolt end of bolt assembly one is located inside the countersunk groove. When constructing and assembling the prefabricated concrete water tank, the longitudinal waist hole is filled with concrete so that the nut end of bolt assembly one or bolt assembly two is pre-embedded in the corresponding countersunk groove, avoiding corrosion caused by contact between the nut end of bolt assembly one or bolt assembly two and water or a humid environment during later use.

[0011] A further preferred technical solution is that the longitudinal waist hole is filled with concrete to fix the bolt assembly one or bolt assembly two passing through it to the corresponding longitudinal support arm as a whole. On the one hand, this ensures that the bolt assembly and the corresponding longitudinal support leg are cast and connected as a whole, ensuring the overall structural stability of the support frame; on the other hand, it ensures that the nut ends of bolt assembly one or bolt assembly two are pre-embedded in the corresponding countersunk grooves, preventing corrosion of the nut ends of bolt assembly one or bolt assembly two due to contact with water or a humid environment during later use.

[0012] A further preferred technical solution includes a longitudinal groove on one longitudinal support arm of the frame unit facing the corresponding pool side panel, for accommodating the corresponding side panel connecting assembly. This longitudinal groove, together with the inner surfaces of the two corresponding pool side panels, forms a second longitudinal casting cavity for casting and connecting the longitudinal support arm of the frame unit facing the corresponding pool side panel to the joint of the two corresponding pool side panels. The frame unit located on the outer periphery of the support frame is connected to the corresponding side panel connecting assembly and the joint of the two pool side panels by concrete poured into the second longitudinal casting cavity. This further ensures the connection strength and integrity between the support frame and the outer periphery of the pool side panels, while also improving the sealing and leak-proof performance of the pool side panel joint.

[0013] A further preferred technical solution includes that each of the two opposing outer vertical surfaces of the two longitudinal supports on frame unit two and the outer vertical surface of one longitudinal support facing frame unit two on frame unit one are provided with inclined surfaces located at their two vertical edges. Each group of four adjacent prefabricated frame units is joined together by the corresponding inclined surfaces on the four opposing longitudinal supports, and a longitudinal casting cavity is formed at the cross joint between each group of four adjacent prefabricated frame units for casting and connecting the four opposing longitudinal supports together. The fact that each group of four adjacent prefabricated frame units is joined together by the corresponding inclined surfaces on the four opposing longitudinal supports improves the ease of positioning during assembly and ensures that the joint naturally forms the longitudinal casting cavity, guaranteeing the convenience and efficiency of the support frame assembly.

[0014] A further preferred technical solution is that a horizontal groove along its length is formed in the middle of the upper end face of the horizontal top arm, and the end of the reinforcing bar is located at the bottom of the horizontal groove. The horizontal groove helps to improve the casting stability of the joint between the top of the precast frame unit and the corresponding water tank top slab.

[0015] A further preferred technical solution is that a number of support beams are spaced apart between the two longitudinal arms of the prefabricated frame unit to connect them. These support beams improve the connection strength between the two longitudinal arms, ensuring that the prefabricated frame unit as a whole has excellent structural rigidity.

[0016] The second objective of this utility model is to design a water tank, which is a prefabricated concrete water tank, including a water tank frame formed by several water tank side plates connected by side plate connecting components, and the aforementioned support frame is provided inside the water tank frame.

[0017] This utility model provides a water tank support frame that prevents metal components such as reinforcing bars and mounting bolts from being exposed in water or humid environments. It has good corrosion resistance, the same lifespan as the side panels of the water tank, and does not require frequent periodic inspections and maintenance, thus saving labor maintenance costs. It features strong tensile and shear resistance and good buoyancy resistance, effectively bearing the water load inside the water tank, the structural self-weight, and external additional loads. It is especially suitable for supporting the top slab of the water tank, reducing displacement or cracks in the side panels caused by loads, and ensuring the overall structural safety of the prefabricated concrete water tank.

[0018] The advantages and beneficial effects of this utility model are as follows:

[0019] 1. This utility model discloses a support frame for the interior of a prefabricated concrete water tank. Several horizontal and vertical support frames are sequentially assembled from several prefabricated frame units connected by a second tensioning mechanism. Several prefabricated frame units located circumferentially on the outer periphery of the support frame are fixedly connected to the corresponding side panels of the water tank via a first tensioning mechanism. Furthermore, every four adjacent prefabricated frame units are fixedly connected by concrete poured at the cross joints. This ensures that the support frame and the outer periphery of the water tank side panels form a concrete structure with good overall consistency, high structural strength, good stability, and high compressive strength. Therefore, the prefabricated concrete water tank constructed using this utility model's support frame possesses strong tensile and shear resistance. The support frame of this invention features excellent anti-buoyancy capabilities. It avoids exposing metal components such as reinforcing bars and mounting bolts to water or humid environments, exhibits good corrosion resistance, has the same lifespan as the pool side panels, and requires no frequent periodic inspections or maintenance, thus saving on labor costs. The precast frame units of the concrete precast components ensure that the support frame has high compressive strength, thereby ensuring that the assembled concrete pool using this support frame can effectively withstand the water load inside the pool, the structural self-weight, and external additional loads (such as the weight of vehicles and equipment). It is particularly suitable for supporting the top slab of the pool, reducing displacement or cracks in the pool side panels caused by loads, and ensuring the overall structural safety of the assembled concrete pool.

[0020] 2. The prefabricated frame unit has a pre-embedded steel cage inside. Several upward-extending steel bars are spaced at intervals along the length of the top of the prefabricated frame unit. The height of the prefabricated frame unit is equal to that of the side panel of the water tank. When assembling a prefabricated concrete water tank using the support frame of this utility model, the steel bars at the top of the prefabricated frame unit extend into the joint between two adjacent water tank top panels and are welded and fixed together with the steel bars exposed on the outer periphery of the water tank top panel. Concrete is then poured at the joint to ensure the convenience and stability of the connection between the support frame and the water tank top panel.

[0021] 3. The prefabricated frame unit, the first tensioning connection mechanism, and the second tensioning connection mechanism are ingeniously and reasonably designed. Furthermore, the two longitudinal support arms of the prefabricated frame unit are provided with longitudinal waist holes. Thus, when four adjacent prefabricated frame units are connected, the bolt assembly 2 passing through one set of relative longitudinal support arms and the bolt assembly 2 passing through another set of relative longitudinal support arms can avoid each other, thereby ensuring the smoothness of the assembly of the support frame of this utility model.

[0022] 4. The end of the longitudinal waist hole facing the inner side of frame unit one or frame unit two is designed as a countersunk groove. When two prefabricated frame units are fixedly connected by bolt assemblies two passing through the corresponding longitudinal waist holes on two opposing longitudinal support arms, the nut end or bolt end of bolt assembly two is located inside the countersunk groove. Similarly, when the longitudinal support leg on frame unit one is connected to the corresponding water tank side plate through bolt assembly one, the nut end or bolt end of bolt assembly one is located inside the countersunk groove. When constructing and assembling a prefabricated concrete water tank, the longitudinal waist hole is filled with concrete so that the nut end of bolt assembly one or bolt assembly two is pre-embedded inside the corresponding countersunk groove, avoiding corrosion caused by contact with water or a humid environment during later use.

[0023] 5. The frame unit one located on the outer periphery of the support frame is connected to the corresponding side plate connecting components and the joint of the two water tank side plates by pouring concrete inside the longitudinal pouring cavity two. This further ensures the connection between the support frame and the outer periphery of the water tank side plates and improves the sealing and anti-leakage performance of the joint of the water tank side plates.

[0024] 6. Each set of four adjacent precast frame units is joined together by corresponding bevels on four opposing longitudinal support arms. This improves the ease of positioning when the four units are joined and spliced, and also allows the joints of the four units to naturally form a longitudinal casting cavity, ensuring the convenience and efficiency of the support frame assembly.

[0025] 7. The water tank of this utility model has a support frame that avoids exposing metal components such as steel bars and mounting bolts in water or humid environments. It has good corrosion resistance, the same lifespan as the side plate of the water tank, and does not require frequent periodic inspection and maintenance, which helps to save labor maintenance costs. It has the characteristics of strong tensile and shear resistance and good buoyancy resistance, and can effectively bear the water load inside the water tank, the self-weight of the structure, and external additional loads. It is especially suitable for supporting the top plate of the water tank, reducing the displacement or cracks of the side plate of the water tank caused by the load, and ensuring the overall structural safety of the prefabricated concrete water tank.

Detailed Implementation

[0040] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0041] Example 1

[0042] like Figures 1-11 As shown, this utility model is a support frame for the interior of a prefabricated concrete water tank, including several corresponding parallel and spaced transverse support frames I and several corresponding parallel and spaced longitudinal support frames II. The transverse support frames I and the longitudinal support frames II are vertically and intersectingly fixed together. The transverse support frames I and the longitudinal support frames II are all formed by sequentially splicing together several prefabricated frame units. Two prefabricated frame units that are connected to each other are fixedly connected together by a tensioning connection mechanism II. Every four adjacent prefabricated frame units are fixedly connected together by concrete poured at the cross joint. Several prefabricated frame units located circumferentially on the outer periphery of the support frame are fixedly connected to the corresponding water tank side plate 5 by a tensioning connection mechanism I.

[0043] Preferably, a steel cage is pre-embedded inside the prefabricated frame unit, and a number of upwardly extending steel bar heads C are spaced at intervals along the length direction at the top of the prefabricated frame unit. The height of the prefabricated frame unit is equal to that of the side plate 5 of the water tank.

[0044] More preferably, each of the prefabricated frame units constituting the horizontal support frame I or the vertical support frame II includes two frame units 1 and several frame units 2. The several frame units 2 are sequentially connected and spliced ​​on the inner side of the horizontal support frame I or the vertical support frame II. The two frame units 1 are correspondingly spliced ​​at both ends of the horizontal support frame I or the vertical support frame II. The frame units 1 and 2 are both "n"-shaped structures with downward openings. Both include a horizontal top arm A at the top and longitudinal support arms B at the lower ends of the horizontal top arm A. The longitudinal support arms B are provided with several longitudinal waist holes E at longitudinal intervals. The two prefabricated frame units that are connected to each other are fixedly connected together by bolt assemblies 2 7 that pass through the two longitudinal waist holes E on the two longitudinal support arms B. The two longitudinal waist holes E and the bolt assemblies 2 7 that pass through them constitute the tensioning connection mechanism 2.

[0045] The frame unit 1 has a longitudinal support arm B facing the corresponding water tank side plate 5. The bolt assembly 3 inside the side plate connecting assembly 6 at the joint between the longitudinal waist hole E and the corresponding two water tank side plates 5 is fixedly connected to the two water tank side plates 5. The longitudinal waist hole E, the side plate connecting assembly 6 and the bolt assembly 3 inside the two constitute the tensioning connection mechanism 1.

[0046] In a further preferred embodiment, one end of the longitudinal waist hole E facing the inner side of frame unit 1 or frame unit 2 is provided as a countersunk groove structure.

[0047] Furthermore, preferably, the longitudinal waist hole E is filled with concrete for fixing the bolt assembly 3 or bolt assembly 7 passing through it to the corresponding longitudinal support arm E as a whole.

[0048] Furthermore, preferably, the frame unit 1 has a longitudinal support arm B facing the corresponding side plate 5 with a longitudinal groove D for accommodating the corresponding side plate connecting assembly 6, and the longitudinal groove D and the inner surfaces of the two corresponding side plates 5 form a longitudinal casting cavity 8 for casting and connecting the longitudinal support arm B of the frame unit 1 facing the corresponding side plate 5 with the joint of the two corresponding side plates 5.

[0049] Furthermore, preferably, a set of oppositely opposed outer vertical surfaces of the two longitudinal arms B on the frame unit 2 and an outer vertical surface of the longitudinal arm B facing the frame unit 1 on the frame unit 2 are provided with inclined surfaces G located at the vertical edges on both sides. Each set of four adjacent prefabricated frame units are fitted together by the inclined surfaces G on the four opposing longitudinal arms B, and a longitudinal casting cavity 4 is formed at the cross joint between each set of four adjacent prefabricated frame units for casting and connecting the four opposing longitudinal arms B together.

[0050] Furthermore, in a more preferred embodiment, a horizontal groove H is formed in the middle of the upper end face of the horizontal top arm A, extending along its length, and the reinforcing bar head C is located at the bottom of the horizontal groove H.

[0051] Furthermore, in a more preferred embodiment, a plurality of support beams F are provided at intervals between the two longitudinal arms B of the prefabricated frame unit to connect the two. Specifically, when the height of the longitudinal arm B is 3 meters, a support beam F is provided in the middle between the two longitudinal arms B of the prefabricated frame unit. If the height of the longitudinal arm B increases by 1 meter, another support beam F is added between the two longitudinal arms B, and so on, to ensure that the prefabricated frame unit as a whole has good structural strength and rigidity.

[0052] This utility model discloses a support frame for the interior of a prefabricated concrete water tank. Several horizontal and vertical support frames are sequentially assembled from prefabricated frame units connected by a second tensioning mechanism. Several prefabricated frame units located circumferentially on the outer periphery of the support frame are fixedly connected to the corresponding side panels of the water tank via a first tensioning mechanism. Furthermore, every four adjacent prefabricated frame units are fixedly connected together by concrete poured at the cross joints. This ensures that the support frame and the outer periphery of the water tank side panels form a concrete structure with good overall consistency, high structural strength, good stability, and high compressive strength. Therefore, the prefabricated concrete water tank constructed using this utility model's support frame possesses strong tensile and shear resistance, and high compressive strength. The support frame of this invention features excellent buoyancy and avoids exposing metal components such as reinforcing bars and mounting bolts to water or humid environments. It exhibits good corrosion resistance, has the same lifespan as the side panels of the pool, and does not require frequent periodic inspections and maintenance, thus saving on labor costs. The precast frame unit of the concrete precast component ensures that the support frame of this invention has high compressive strength, thereby ensuring that the prefabricated concrete pool assembled using this support frame can effectively withstand the water load inside the pool, the structural self-weight, and external additional loads (such as the weight of vehicles and equipment). It is particularly suitable for supporting the top slab of the pool, reducing displacement or cracks in the side panels caused by loads, and ensuring the overall structural safety of the prefabricated concrete pool.

[0053] Example 2

[0054] like Figures 12-13 As shown, a water tank is a prefabricated concrete water tank, comprising a water tank frame formed by several water tank side plates 5 connected by side plate connecting components 6. The water tank frame is provided with the support frame described in Embodiment 1. It also includes several water tank top plates 9 laid on the upper edge of the water tank frame and the top of the support frame. The steel bar head C at the top of each prefabricated frame unit is inserted into the joint between two adjacent water tank top plates 9. The steel bar head 2 9-1 extending outside the outer periphery of the water tank top plate 9 is welded to the steel bar head C, or to the steel bar head 3 extending above the upper edge of the water tank side plate 5. Concrete is poured into the joint between two adjacent water tank top plates 9 and the joint between the outer periphery of the water tank top plate 9 and the upper edge of the water tank frame.

[0055] The construction principle of a water tank in Example 2:

[0056] Step 1: Lay the bottom plate of the pool, hoist several pool side plates 5 onto the bottom plate of the pool, and enclose them to form the pool frame. Two adjacent pool side plates 5 are sealed and connected by a side plate connecting assembly 6. The side plate connecting assembly 6 can be a clamp bolt assembly, including two channel steel clamp plates 6-1 and several bolt assemblies 6-2. Several mounting holes are spaced apart along the length of the two channel steel clamp plates 6-1. A pair of channel steel clamp plates 6-1 are laid on the inner and outer sides of the joint of two adjacent pool side plates 5. The bolt assemblies 6-2 are inserted into the mounting holes on the two channel steel clamp plates 6-1 and clamp the two ends of the two channel steel clamp plates 6-1 and the two pool side plates 5 together. A sealing gasket can also be laid on the side of the channel steel clamp plate 6-1 facing the pool side plate 5.

[0057] Step 2: Hoist several frame units 1 and several frame units 2 into the pool frame, and splice the frame units 1 and several frame units 2 into several corresponding parallel-spaced transverse support frames I and several corresponding parallel-spaced longitudinal support frames II. The several transverse support frames I and several longitudinal support frames II are vertically and intersectingly fixed together. Two prefabricated frame units that are connected to each other are fixed together by bolt assemblies 2 7 that pass through the two longitudinal waist holes E on the two longitudinal support arms B. The longitudinal support arm B of frame unit 1 facing the corresponding pool side plate 5 is fixed together with the two corresponding pool side plates 5 by bolt assemblies 1 3 that pass through the longitudinal waist hole E and the joint position between the two pool side plates 5.

[0058] Step 3: Pour concrete mortar into the interior of longitudinal pouring cavity 1 4, the interior of longitudinal pouring cavity 2 8, and the interior of the longitudinal waist hole E of each longitudinal support arm B. After curing, the support frame of this utility model is formed.

[0059] Step 4: Hoist and lay several pool top slabs 9 onto the top of the pool frame and support frame, ensuring that each pool top slab 9 is positioned on top of a corresponding compartment of the support frame. The steel bar head C at the top of each precast frame unit is inserted into the butt joint between two adjacent pool top slabs 9. The steel bar head 9-1 extending beyond the outer perimeter of the pool top slab 9 is welded to steel bar head C or to steel bar head 3 extending above the upper edge of the pool side panel 5 (see Appendix). Figure 13 );

[0060] Step 5: Finally, pour concrete mortar into the joints between two adjacent top slabs 9 of the pool, as well as into the joints between the outer perimeter of the top slab 9 and the upper edge of the pool frame. After curing, a prefabricated concrete pool is formed (see appendix). Figure 12 ).

[0061] This utility model provides a water tank support frame that prevents metal components such as reinforcing bars and mounting bolts from being exposed in water or humid environments. It has good corrosion resistance, the same lifespan as the side panels of the water tank, and does not require frequent periodic inspections and maintenance, thus saving labor maintenance costs. It features strong tensile and shear resistance and good buoyancy resistance, effectively bearing the water load inside the water tank, the structural self-weight, and external additional loads. It is especially suitable for supporting the top slab of the water tank, reducing displacement or cracks in the side panels caused by loads, and ensuring the overall structural safety of the prefabricated concrete water tank.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
