Description

Technical Field

[0001] This utility model relates to the field of prefabricated water tank technology, specifically to a prefabricated side panel module for a water tank and an ultra-high prefabricated water tank using the same. Background Technology

[0002] A water tank is a water storage facility with seepage prevention capabilities, and it is used in various fields such as fire protection systems, industrial systems, and agricultural systems. Due to the disadvantages of cast-in-place concrete water tank construction, such as large consumption of formwork, long on-site operation time, significant influence from weather, and unstable concrete quality, various structural styles of prefabricated water tanks have emerged on the market, among which prefabricated concrete water tanks are more widely used.

[0003] Prefabricated concrete water tanks (hereinafter referred to as prefabricated water tanks) are constructed as follows: a base is poured, several precast slab units are assembled into the sidewalls of the tank within pre-reserved mounting slots on the base, and then a top slab is laid on the upper end of the sidewalls. The sidewall height of ordinary prefabricated water tanks does not exceed 3 meters, resulting in limited volume. Therefore, ordinary prefabricated water tanks have a certain problem with insufficient water storage capacity when supplying water for large-scale fire fighting. To meet the large water supply demands of urban fire-fighting water supply systems, ultra-high prefabricated water tanks (sidewall height > 3 meters) are gradually becoming popular.

[0004] Precast side panel units used for assembling ordinary prefabricated water tank side panels are mostly precast panels with an integrated structural design. These are manufactured in the factory and then transported to the construction site for assembly into water tank side panels. Because the side wall height of ultra-high prefabricated water tanks is significantly increased compared to ordinary prefabricated water tanks, if the precast side panel units used for assembling ultra-high prefabricated water tank side panels are designed as integrated precast panels, their weight will increase significantly, consequently increasing the difficulty of hoisting and transportation. Furthermore, due to the excessive weight of the precast side panel units assembled into ultra-high prefabricated water tank side panels, they are prone to breakage or cracking during transportation due to bumps, thus significantly increasing the probability of scrapping. This utility model aims to propose a precast side panel module for water tanks and an ultra-high prefabricated water tank using it, in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a prefabricated side panel module for a water tank and an ultra-high prefabricated water tank using it. It adopts a split structural design, and the inner and outer side panels have a casting cavity for casting and connecting them into one unit. Compared with a prefabricated side panel unit with an integrated structure of the same area, the weight is significantly reduced, thereby significantly reducing the difficulty of lifting and transporting the prefabricated side panel module. At the same time, it effectively reduces or eliminates pressure damage or cracking caused by the excessive weight and bumps of the prefabricated side panel module during transportation, thus reducing the probability of transportation failure. When the prefabricated side panel module of this invention is assembled into a side panel of an ultra-high prefabricated water tank on the construction site, the casting cavity between the inner and outer side panels of the prefabricated side panel module is filled with concrete to connect them into one unit. This ensures that the prefabricated side panel module has good sealing and leak-proof performance, anti-buoyancy, and high strength when assembled into a side panel, which helps to extend the overall service life of the ultra-high prefabricated water tank.

[0006] One of the objectives of this utility model is to design a prefabricated side panel module for a water tank, comprising an inner side panel and an outer side panel that are stacked in parallel. The inner side panel and the outer side panel are connected together by a number of detachable tensioning connection components disposed between them, and a casting cavity is provided between the inner side panel and the outer side panel for casting and connecting them into one piece.

[0007] This utility model discloses a prefabricated side panel module for a water tank. It features a split structural design with a casting cavity between the inner and outer side panels for seamlessly connecting them. Compared to a prefabricated side panel unit with the same area and size, this significantly reduces weight, thereby greatly simplifying lifting and transportation. Simultaneously, it effectively reduces or eliminates pressure damage or cracking caused by excessive weight and bumps during transportation, thus lowering the likelihood of transport failure. When the prefabricated side panel module is assembled into a side panel for an ultra-high prefabricated water tank on the construction site, the casting cavity between the inner and outer side panels is filled with concrete to connect them, ensuring good sealing and leak-proof performance, buoyancy resistance, and high strength, which helps extend the overall service life of the ultra-high prefabricated water tank.

[0008] A preferred technical solution is that several truss reinforcement bars are pre-embedded on the opposing sides of the inner and outer side plates, respectively, and exposed into the casting cavity between them. The reinforcement bars pre-embedded in the inner or outer side plates extend out of their left and right sides and top surface to form exposed reinforcement joints. When the prefabricated side plate modules of this utility model are assembled into prefabricated water tank side plates on the construction site, two adjacent prefabricated side plate modules are welded and fixed together by the reinforcement joints exposed on the vertical surfaces of the opposing sides. Similarly, the reinforcement joints exposed on the top surface of the prefabricated side plate modules can be welded and fixed together with the reinforcement joints exposed on the outer periphery of the top plate of the water tank. This ensures good overall structural strength of the prefabricated water tank and helps to reduce the construction difficulty and extend the service life of the prefabricated water tank.

[0009] A further preferred technical solution includes several downward-facing, corresponding notches and slots at intervals on the lower ends of the inner and outer side plates. Reinforcing bars pre-embedded inside the lower ends of the inner or outer side plates extend or pass through the corresponding notches and slots. When assembling a prefabricated water tank using the prefabricated side plate modules of this invention, connecting reinforcing bars can be threaded through the notches and slots. These connecting reinforcing bars are then welded and fixed together with the pre-embedded reinforcing cages inside the side plate mounting grooves on the upper surface of the water tank bottom plate. The lower end of the prefabricated side plate module is then cast into the side plate mounting groove on the upper surface of the water tank bottom plate, ensuring high installation stability of the lower end of the water tank side plate within the side plate mounting groove on the upper surface of the water tank bottom plate.

[0010] A preferred technical solution also includes an auxiliary reinforcing cage filled inside the casting cavity between the inner and outer side panels, with the reinforcing bars on the auxiliary cage extending out to the left and right ends and the top end of the casting cavity to form exposed reinforcing bar joints. When the prefabricated side panel module of this utility model is assembled into a water tank side panel using poured concrete, the auxiliary reinforcing cage located inside the casting cavity helps to further improve the overall structural stability and buoyancy resistance of the water tank side panel, and extend its overall service life.

[0011] A preferred technical solution is that the detachable tensioning connection assembly is a locking bolt assembly, which includes a pre-embedded screw section, a detachable screw section, an internal threaded sleeve, and a locking nut. One end of the pre-embedded screw section is pre-embedded inside the inner side plate, and the other end is exposed outside the side of the inner side plate with truss reinforcement. The outer side plate has several through-hole mounting holes. When the inner side plate and the outer side plate are connected together by the corresponding overlapping of the detachable tensioning connection assembly, the internal threaded sleeve on the locking bolt assembly passes through the mounting hole on the outer side plate. One end of the detachable screw section is screwed to the outer end of the internal threaded sleeve that passes through the mounting hole on the outer side plate. The other end of the detachable screw section is exposed outside the side of the outer side plate away from the inner side plate and screwed with the locking nut. The end of the pre-embedded screw section exposed outside the side of the inner side plate with truss reinforcement is screwed to the inner end of the corresponding internal threaded sleeve. The locking bolt assembly has a clever and reasonable structural design. The pre-embedded screw section is embedded in the inner side plate. The detachable screw section can be removed and reused after the prefabricated side plate module of the water tank is assembled into the side plate of the water tank. This helps to improve the reusability of the tool and is economical and practical.

[0012] A further preferred technical solution is that the locking bolt assembly one also includes a water-stop plate with a through hole, which passes through the shoulder of the pre-embedded bolt section exposed to the outer end of the side of the inner side plate with the truss reinforcement. The water-stop plate, located inside the casting cavity, passes through the pre-embedded bolt section of the locking bolt assembly one. When the prefabricated side plate module of the water tank is assembled into a water tank side plate, the water-stop plate improves the casting firmness of the pre-embedded bolt section inside the water tank side plate and also helps to improve the sealing and leak-proof performance of the water tank side plate at the location of the locking bolt assembly one.

[0013] A further preferred technical solution is that a waterproof and corrosion-resistant metal plate is pre-embedded and fixed on the side of the inner side plate facing away from the truss reinforcement. The pre-embedded waterproof and corrosion-resistant metal plate on the side of the inner side plate facing the interior of the pool helps to improve the sealing and leak-proof performance of the prefabricated pool assembled using the prefabricated side plate modules of this invention.

[0014] The second objective of this utility model is to design an ultra-high prefabricated water tank, including a water tank side panel, wherein the water tank side panel is formed by connecting and sealing several of the above-mentioned prefabricated water tank side panel modules through a joint connection structure.

[0015] This utility model discloses an ultra-high prefabricated water tank. The side panels of the water tank are formed by connecting and sealing several prefabricated side panel modules as described above through a joint connection structure. The prefabricated side panel modules are lightweight and easy to install, which helps to reduce the overall construction difficulty of the ultra-high prefabricated water tank and improve construction efficiency. The inner and outer side panels of the prefabricated side panel modules are connected as one unit by secondary pouring of concrete in the pouring cavity, ensuring that the side panels of the ultra-high prefabricated water tank have good overall structural stability, good buoyancy resistance, good sealing and leakage prevention, and durability.

[0016] A preferred technical solution is that the inner side plate and the outer side plate are respectively pre-embedded with steel bars, and the steel bars pre-embedded in the inner side plate or the outer side plate extend out of their left and right sides and the top end to form an exposed steel bar joint.

[0017] It also includes an auxiliary steel cage that fills the casting cavity between the inner and outer side plates, and the steel bars on the auxiliary steel cage extend out of the left and right ports and the upper port of the casting cavity to form an exposed steel bar joint.

[0018] When several prefabricated side panel modules of the water tank are spliced ​​together to form a water tank side panel, two adjacent prefabricated side panel modules are fixedly connected together by welding corresponding steel bar joints 1 and 2 on their opposite side surfaces. A set of U-shaped channel steel is laid on both the inner and outer sides of the joint between two adjacent prefabricated side panel modules. The set of U-shaped channel steel is fixedly connected together by locking bolt assemblies 2 that pass through corresponding mounting holes 2 on both. Concrete is poured into the longitudinal cavity formed by the splicing of the two adjacent prefabricated side panel modules and the set of U-shaped channel steel, as well as into the casting cavity on the prefabricated side panel module. The set of U-shaped channel steel, the locking bolt assemblies 2 used to connect the set of U-shaped channel steel, and the concrete poured into the longitudinal cavity constitute the joint connection structure. The joint connection structure is ingeniously and reasonably designed, ensuring the smooth construction and application of this utility model's ultra-high prefabricated water tank.

[0019] A further preferred technical solution includes a pool bottom plate, wherein the lower end of the pool side plate is cast and fixed inside a pre-reserved side plate installation groove on the outer periphery of the upper surface of the pool bottom plate, and the reinforcing bars located inside the notch groove at the lower end of the prefabricated pool side plate module are welded and fixedly connected to the circumferential reinforcing cages pre-embedded in the side walls of the side plate installation groove by connecting reinforcing bars perpendicularly passing through the notch groove; a diagonal brace is also fixed between the upper surface of the pool bottom plate and the U-shaped channel steel. The reinforcing bars inside the notch groove at the lower end of the prefabricated pool side plate module are welded and fixedly connected to the circumferential reinforcing cages pre-embedded in the side walls of the side plate installation groove by connecting reinforcing bars perpendicularly passing through the notch groove, thereby further ensuring the installation firmness and usage stability of the prefabricated pool side plate module on the upper surface of the pool bottom plate, and helping to extend the overall service life of the ultra-high prefabricated pool; the diagonal brace helps to improve the installation stability of the pool side plate on the pool bottom plate in the ultra-high prefabricated pool.

[0020] The advantages and beneficial effects of this utility model are as follows:

[0021] 1. This utility model discloses a prefabricated side panel module for a water tank, which adopts a split structural design. The inner and outer side panels have a casting cavity for connecting them into a single unit. Compared to a prefabricated side panel unit with an integrated structure of the same size, the weight is significantly reduced, thereby significantly reducing the difficulty of lifting and transporting the prefabricated side panel module. Simultaneously, it effectively reduces or eliminates pressure damage or cracking caused by excessive weight and bumps during transportation, thus reducing the probability of transport failure. When the prefabricated side panel module is assembled into a side panel for an ultra-high prefabricated water tank on the construction site, the casting cavity between the inner and outer side panels of the module is filled with concrete to connect them, ensuring good sealing and leak-proof performance, anti-buoyancy, and high strength when the module is assembled into a side panel, thus helping to extend the overall service life of the ultra-high prefabricated water tank.

[0022] 2. When the prefabricated side panel modules of this utility model are assembled into prefabricated side panels of a prefabricated water tank on the construction site, two adjacent prefabricated side panel modules are welded and fixed together by steel bar joints exposed on the outside of the vertical surfaces on both sides. Similarly, steel bar joints exposed on the outside of the upper surface of the prefabricated side panel modules can be welded and fixed together with steel bar joints exposed on the outside of the outer periphery of the top plate of the water tank. This ensures the overall structural strength of the prefabricated water tank and helps to reduce the construction difficulty and extend the service life of the prefabricated water tank.

[0023] 3. When assembling a prefabricated side panel module for a prefabricated water tank using this utility model, connecting steel bars can be threaded through the notch groove. The steel bars embedded in the lower end of the inner side panel and the lower end of the outer side panel and extending or threading through the notch groove are welded and fixed together with the pre-embedded steel cages inside the side panel mounting groove on the upper surface of the water tank bottom plate. Then, the lower end of the prefabricated side panel module is poured into the side panel mounting groove on the upper surface of the water tank bottom plate, thereby ensuring that the lower end of the water tank side panel is firmly installed inside the side panel mounting groove on the upper surface of the water tank bottom plate.

[0024] 4. It also includes an auxiliary reinforcing cage filled inside the casting cavity between the inner and outer side panels, with the reinforcing bars on the auxiliary cage extending out to the left and right ends and the top end of the casting cavity to form exposed reinforcing bar joints. When the prefabricated side panel module of this utility model is assembled into a water tank side panel using poured concrete, the auxiliary reinforcing cage located inside the casting cavity helps to further improve the overall structural stability and buoyancy resistance of the water tank side panel, and extend its overall service life.

[0025] 5. The locking bolt assembly has a clever and reasonable structural design. The pre-embedded screw section is embedded in the inner side plate. The detachable screw section can be removed and reused after the prefabricated side plate module of the water tank is assembled into the side plate of the water tank. This helps to improve the reusability of the tool and is economical and practical.

[0026] 6. A water-stop plate located inside the casting cavity is connected to the pre-embedded screw section of the locking bolt assembly 1. When the prefabricated side panel module of the water tank is assembled into a water tank side panel, the water-stop plate improves the casting firmness of the pre-embedded screw section inside the water tank side panel on the one hand, and helps to improve the sealing and leak-proof performance of the water tank side panel at the location of the locking bolt assembly 1 on the other hand.

[0027] 7. A waterproof and corrosion-resistant metal plate is pre-embedded on the side of the inner side panel facing the inside of the pool, which helps to improve the sealing and leak-proof performance of the prefabricated pool assembled using the prefabricated side panel modules of this utility model.

[0028] 8. The present invention relates to an ultra-high prefabricated water tank, wherein the side panels of the water tank are formed by connecting and sealing several of the above-mentioned prefabricated side panel modules through a joint connection structure. The prefabricated side panel modules are lightweight and easy to install, thereby helping to reduce the overall construction difficulty of the ultra-high prefabricated water tank and improve construction efficiency. The inner and outer side panels of the prefabricated side panel modules are connected as one unit by secondary pouring of concrete in the pouring cavity, ensuring that the side panels of the ultra-high prefabricated water tank have good overall structural stability, good buoyancy resistance, good sealing and leakage prevention, and durability.

[0029] 9. The reinforcing bars inside the notch groove at the lower end of the prefabricated side panel module of the water tank are welded and fixed together with the circumferential reinforcing bar cages embedded in the side wall of the side panel installation groove by connecting reinforcing bars that are vertically inserted into the notch groove. This further ensures the installation firmness and usage stability of the prefabricated side panel module of the water tank on the upper surface of the water tank bottom plate, and helps to extend the overall service life of the ultra-high prefabricated water tank. The diagonal bracing helps to improve the installation stability of the water tank side panel on the water tank bottom plate in the ultra-high prefabricated water tank. Attached Figure Description

[0042] 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.

The outer side plate 2 has several through-hole mounting holes 2-1. When the inner side plate 1 and the outer side plate 2 are correspondingly overlapped and connected together by the detachable tensioning connection assembly, the... The internal threaded sleeve 3-3 on the locking bolt assembly 3 passes through the mounting hole 2-1 on the outer side plate 2. One end of the detachable screw section 3-2 is screwed to the outer end of the internal threaded sleeve 3-3 passing through the mounting hole 2-1 on the outer side plate 2. The other end of the detachable screw section 3-2 is exposed to the outer side of the outer side plate 2 away from the inner side plate 1 and is screwed with the locking nut 3-4.

[0052] This utility model discloses a prefabricated side panel module for a water tank. It features a split structural design with a casting cavity between the inner and outer side panels for seamlessly connecting them. Compared to a prefabricated side panel unit with the same area and size, this significantly reduces weight, thereby greatly simplifying lifting and transportation. Simultaneously, it effectively reduces or eliminates pressure damage or cracking caused by excessive weight and bumps during transportation, thus lowering the likelihood of transport failure. When the prefabricated side panel module is assembled into a side panel for an ultra-high prefabricated water tank on the construction site, the casting cavity between the inner and outer side panels is filled with concrete to connect them, ensuring good sealing and leak-proof performance, buoyancy resistance, and high strength, which helps extend the overall service life of the ultra-high prefabricated water tank.

A set of U-shaped channel steel 6 is laid on the inner and outer sides of the joint position of two adjacent prefabricated side panel modules A. The set of U-shaped channel steel 6 is fixedly connected together by locking bolt assembly 7 that passes through the corresponding mounting holes 2 on both. Concrete is poured together inside the longitudinal cavity D formed by splicing and enclosing the two adjacent prefabricated side panel modules A and the set of U-shaped channel steel 6, as well as inside the casting cavity C on the prefabricated side panel module A. The set of U-shaped channel steel 6, the locking bolt assembly 7 used to connect the set of U-shaped channel steel 6, and the concrete poured inside the longitudinal cavity D constitute the joint connection structure.

After the concrete has cured, several precast side panel modules A are poured a second time to form an integrated side panel 9. Several side panels 9 are then used to form the water tank frame structure (see Appendix). Figure 10 ).

[0064] A water tank top plate can also be laid on the port of the water tank frame structure; in addition, the detachable screw section 3-2, internal thread sleeve 3-3 and locking nut 3-4 on the locking bolt assembly 3 can be disassembled and reused, and the mounting hole 2-1 on the side plate 9 of the water tank can be filled and smoothed with cement mortar.
