Description

Technical Field

[0001] This utility model relates to the field of prefabricated water tank technology, specifically to a lightweight prefabricated side panel of a water tank, a side panel connection structure, and a cylindrical prefabricated water tank. Background Technology

[0002] In construction engineering, cylindrical concrete water tanks are widely used in water storage, sewage treatment, and other fields. Traditional cylindrical concrete water tanks are usually constructed by on-site casting, which has problems such as long construction period, large amount of on-site work, and great susceptibility to weather. Therefore, various types of prefabricated cylindrical water tanks with different structural styles have also appeared on the market.

[0003] Currently, most widely used cylindrical prefabricated water tanks are constructed by splicing together precast curved side panels with a solid structure and a certain curvature using joint components. The problems with this type of cylindrical prefabricated water tank are: (1) the structural strength at the joints of the circular water tank sidewalls, formed by splicing together several precast curved side panels using joint components, is poor, making them prone to water seepage and even cracking during later use, requiring frequent maintenance and repair; (2) the overall consistency and durability of the circular water tank sidewalls are poor, severely limiting the service life of the cylindrical concrete water tank; (3) the precast curved side panels are manufactured in the factory, resulting in a large overall weight, making transportation to the water tank construction site difficult and costly. Therefore, this utility model proposes a lightweight precast water tank side panel, a side panel connection structure, and a cylindrical prefabricated water tank to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a lightweight prefabricated side panel for a water tank, a side panel connection structure, and a cylindrical assembled water tank. The lightweight prefabricated side panel has a casting cavity inside, which significantly reduces the weight compared to an arc-shaped prefabricated side panel with an integral solid structure of the same area, thereby significantly reducing the lifting difficulty, transportation difficulty, and transportation cost of the prefabricated side panel. The cylindrical assembled water tank assembled from the lightweight prefabricated side panels of this invention has an annular casting cavity inside the side wall, which is spliced ​​from the casting cavities inside several lightweight prefabricated side panels. After the concrete is poured and cured inside the annular casting cavity, a water tank side wall with good overall consistency, long service life, good sealing and leak-proof performance, good buoyancy resistance, and high self-strength is formed. This significantly improves the structural strength of the joints of the water tank side wall, reduces or eliminates the risk of cracking or water seepage at the joints of the water tank side wall, effectively reduces the frequency of later maintenance and repair, and has good economic benefits and strong practicality.

[0005] One objective of this utility model is to design a lightweight precast side panel for a water tank, comprising an inner arc-shaped metal plate, an inner arc-shaped steel cage, an outer arc-shaped metal plate, an outer arc-shaped steel cage, and a precast concrete layer poured onto the outer arc-shaped steel cage, arranged sequentially. The concave arc surfaces of all five components face the same side. The panel also includes several tensioning connectors that tighten and connect the inner arc-shaped metal plate, the inner arc-shaped steel cage, the outer arc-shaped metal plate, and the outer arc-shaped steel cage together. The inner arc-shaped metal plate, the inner arc-shaped steel cage, and the outer arc-shaped metal plate enclose a casting cavity for pouring and connecting the three components into a single unit.

[0006] This utility model discloses a lightweight prefabricated side panel for a water tank, which has an internal casting cavity. Compared with an integral solid structure arc-shaped prefabricated side panel of the same area, the weight is significantly reduced, thereby significantly reducing the lifting difficulty, transportation difficulty, and transportation cost of the prefabricated side panel for the water tank. The cylindrical prefabricated water tank side wall assembled by the lightweight prefabricated side panel of this utility model has an annular casting cavity formed by splicing several casting cavities inside the lightweight prefabricated side panel. After concrete is poured and cured inside the annular casting cavity, a water tank side wall with good overall consistency, long service life, good sealing and leakage prevention performance, good buoyancy resistance, and high self-strength is formed. This significantly improves the structural strength of the joints of the water tank side wall, reduces or eliminates the risk of cracking or water leakage at the joints of the water tank side wall, effectively reduces the frequency of later maintenance and repair, and has good economic benefits and strong practicality.

[0007] The preferred technical solution is that the tensioning connectors are a plurality of radial reinforcing bars extending radially from the concave arc side of the outer arc-shaped reinforcing cage. The free ends of the radial reinforcing bars pass sequentially through corresponding mounting holes on the outer arc-shaped metal plate, the inner arc-shaped reinforcing cage, and are welded and fixedly connected to the convex arc side of the inner arc-shaped metal plate. The radial reinforcing bars are also tied and fixedly connected to the inner arc-shaped reinforcing cage. The tensioning connectors are a plurality of radial reinforcing bars extending radially from the concave arc side of the outer arc-shaped reinforcing cage. The structural design is ingenious and reasonable, ensuring that the outer arc-shaped reinforcing cage, the outer arc-shaped metal plate, the inner arc-shaped reinforcing cage, and the inner arc-shaped metal plate can be well connected together, thereby ensuring that the lightweight precast side plate of this utility model has good overall structural strength after concrete is poured inside the casting cavity.

[0008] A preferred technical solution also includes several raised ribs spaced apart on both the inner and outer arc-shaped metal plates, with the ribs being integrally bent from either the inner or outer arc-shaped metal plate. These raised ribs effectively improve the overall structural strength of the inner or outer arc-shaped metal plate. When pouring concrete into the casting cavity, the ribs also help increase the interlocking force between the concrete and the inner or outer arc-shaped metal plate, resulting in excellent adhesion and firmness between the inner or outer arc-shaped metal plate and the cured concrete layer. This further ensures that the sidewall of the pool formed after pouring concrete into the casting cavity has good structural strength and anti-buoyancy performance.

[0009] A further preferred technical solution is that several of the aforementioned ribs are arranged along the transverse direction on the inner or outer arc-shaped metal plate. The length direction of the ribs is consistent with the length direction of the inner or outer arc-shaped metal plate in the left-right horizontal direction, which to a certain extent improves the stiffness of the inner or outer arc-shaped metal plate along the curved surface, thereby helping to ensure that the sidewalls of the cylindrical prefabricated water tank assembled from the lightweight prefabricated side panels of this utility model remain basically on the same circumference.

[0010] A further preferred technical solution includes: both ends of the inner arc-shaped reinforcing cage have reinforcing bar heads extending outwards to the left and right sides of the casting cavity; both ends of the inner arc-shaped reinforcing cage have reinforcing bar heads extending outwards to the upper and lower sides of the casting cavity; both ends of the outer arc-shaped reinforcing cage have reinforcing bar heads extending outwards to the left and right sides of the precast concrete layer; and both ends of the inner arc-shaped metal plate have plate joints extending outwards to the left and right sides of the casting cavity. When the lightweight precast side panels of this utility model are assembled into prefabricated side walls of a water tank on the construction site, the reinforcing bar heads (first, third, and plate joints) on the two vertically aligned sides of two adjacent arc-shaped precast side panels are fixedly connected; the reinforcing bar heads (third, fourth, and plate joints) are fixedly connected; and the reinforcing bar heads (second, fourth, and fifth) on the two horizontally aligned sides of two adjacent arc-shaped precast side panels are fixedly connected, ensuring high structural strength and durability at the joints of the water tank side wall.

[0011] The second objective of this utility model is to design a side plate connection structure for connecting adjacent arc-shaped prefabricated side plates on the side wall of a cylindrical prefabricated water tank. The arc-shaped prefabricated side plates are the aforementioned lightweight prefabricated side plates for water tanks. The steel bars on the two vertical sides of two adjacent arc-shaped prefabricated side plates are fixedly connected in a corresponding manner: steel bar head 1, steel bar head 3, and plate joint are fixedly connected in a corresponding manner. The steel bars on the two horizontal arc-shaped surfaces of two adjacent arc-shaped prefabricated side plates are fixedly connected in a corresponding manner. Furthermore, concrete is poured into the joint of the two adjacent arc-shaped prefabricated side plates and into the casting cavity of the arc-shaped prefabricated side plates.

[0012] This utility model provides a side plate connection structure with ingenious and reasonable structural design, simple construction operation steps, low requirements for the quality of construction personnel, and high overall construction efficiency. It ensures the smooth construction of cylindrical prefabricated water tanks and ensures that the joint of the two arc-shaped prefabricated side plates has good structural strength, thereby helping to reduce the frequency of later maintenance of cylindrical prefabricated water tanks and extend their service life.

[0013] The preferred technical solution is that the reinforcing bars on the two vertically opposite sides of two adjacent curved precast side panels are welded and fixed together, and the plate joints are overlapped and fixed together. Similarly, the reinforcing bars on the two horizontally opposite sides of two adjacent curved precast side panels are welded and fixed together. The reinforcing bars on the butt joint surfaces of adjacent curved precast side panels are welded and fixed together, and the plate joints are overlapped and fixed together. This fixing method is simple, has good stability, ensures good sealing and waterproofing performance at the joints of the pool side walls, and achieves high construction efficiency.

[0014] A further preferred technical solution is that two adjacent curved prefabricated side panels are fixedly connected by a clamping assembly, and two adjacent curved prefabricated side panels are fixedly connected by a clamping assembly. The fixed connection of adjacent curved prefabricated side panels by clamping assemblies further improves the structural strength of the joints in the pool sidewalls and the overall consistency of the pool sidewalls.

[0015] A further preferred technical solution is that the clamping assembly includes a channel steel and several bolt assemblies. The bolts of the bolt assemblies are inserted longitudinally at intervals into the joint between two adjacent arc-shaped prefabricated side plates. The inner end of the bolt is welded and fixedly connected to the inner arc-shaped reinforcing cage. The channel steel is laid outside the joint between the two adjacent arc-shaped prefabricated side plates. The outer end of the bolt extends to the outside of the joint between the two adjacent arc-shaped prefabricated side plates and passes through the corresponding mounting hole on the channel steel. The outer end of the bolt is also screwed with a locking nut for pressing the channel steel against the outer surface of the corresponding two adjacent arc-shaped prefabricated side plates.

[0016] The clamping assembly two includes a flat steel plate and several bolt assemblies two. The bolts of these bolt assemblies two are radially inserted at intervals along a horizontal direction into the joint between two adjacent curved precast side plates. The inner ends of the bolts are welded and fixedly connected to the inner curved reinforcing cage. The flat steel plate is laid outside the joint between the two adjacent curved precast side plates. The outer ends of the bolts extend outside the joint between the two adjacent curved precast side plates and pass through corresponding mounting holes on the flat steel plate. A locking nut is also screwed onto the outer end of the bolt to secure the flat steel plate against the outer surfaces of the corresponding two adjacent curved precast side plates. The clamping assemblies one and two have ingenious and reasonable structural designs, good adaptability to the joint positions of adjacent curved precast side plates, high feasibility for application, and strong practicality.

[0017] The third objective of this utility model is to design a cylindrical prefabricated water tank, wherein the sidewall of the cylindrical prefabricated water tank is formed by connecting the aforementioned lightweight prefabricated side panels via the aforementioned side panel connection structure.

[0018] This utility model discloses a cylindrical prefabricated water tank.
