Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated water tanks, in particular to a connection structure between a precast roof slab and a precast side slab of a water tank and a prefabricated water tank. Background Technique

[0002] Water tanks can be applied in various fields. For example, water tanks are used in various fields of life such as fire protection systems, industrial systems, and agricultural systems. The traditional concrete water tank is made of cast-in-place concrete at the construction site, which has problems such as multiple operation surfaces crossing at the construction site, a large number of types of work and construction machinery and equipment used, and the water tank is prone to cracking, and the pool pit is prone to collapse, resulting in a large amount of construction formwork work, a long construction period, great difficulty in on-site management, and potential safety hazards. At the same time, it is difficult to ensure that it will not affect the surrounding environment. These series of exposed problems make the traditional cast-in-place concrete water tank unable to meet the current high-efficiency and rapid development pace.

[0003] In a prefabricated concrete water tank (referred to as a prefabricated water tank), the precast side slab unit and the precast roof slab unit involved can be mass-produced and processed in a factory. The process of constructing a prefabricated water tank on-site is relatively simple, involves less tools, and has a short construction period. It not only helps to greatly reduce the pollution to the environment caused by on-site construction, but also helps to improve the overall quality of the water tank and eliminate or reduce the hidden danger of water tank cracking, bringing about a revolution in the field of concrete water tank construction.

[0004] At present, the construction process of a prefabricated concrete water tank with an assembled structure is generally as follows: pour the bottom plate, and a side plate installation groove is reserved on the outer peripheral side of the upper end surface of the bottom plate. Hoist a number of prefabricated side plate units and install them in sequence inside the side plate installation groove on the upper end surface of the bottom plate. The vertical side surfaces of two adjacent side plate units are fixedly connected by welding exposed steel bar joints, and a sealing component is laid or concrete is poured at the joint position between the two to form the water tank side plate. The upper end surface of the water tank side plate and the outer peripheral side surface of the water tank top plate are fixedly connected by welding exposed steel bar joints, and after formwork is supported at the joint position between the two, concrete is poured. After the concrete solidifies, the upper end surface of the water tank side plate is connected to the outer peripheral side surface of the water tank top plate. The problems existing in the construction method of the prefabricated concrete water tank with an assembled structure are as follows: (1) It is difficult to support the formwork between the upper end surface of the water tank side plate and the outer peripheral side surface of the water tank top plate, and there is a large joint between two adjacent formworks at the corner position of the water tank. A large amount of concrete slurry is likely to overflow during concrete pouring, resulting in waste of concrete resources and poor economic benefits; (2) The amount of concrete slurry that can be filled at the joint position between the upper end surface of the water tank side plate and the outer peripheral side surface of the water tank top plate is small, resulting in leakage, water seepage and other phenomena likely to occur at the joint position between the side plate and the top plate during the later use of the water tank; (3) The amount of concrete slurry that can be filled at the joint position between the upper end surface of the water tank side plate and the outer peripheral side surface of the water tank top plate is small, resulting in local corner peeling of the solidified concrete, making it difficult to ensure the long-term use sealing of the water tank, and frequent maintenance and leakage repair of the water tank are required, which will inevitably increase the later maintenance cost. Therefore, the present utility model proposes a connection structure between a prefabricated top plate and a prefabricated side plate of a water tank in order to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present utility model is to overcome the defects existing in the prior art and provide a connection structure between a precast top plate and a precast side plate of a water tank and an assembled water tank. By arranging a bent metal plate on the outer side of the joint position between the upper end face of the precast side plate and the outer peripheral side face of the precast top plate, a cavity with an upward opening is formed by enclosing the upper end face of the precast side plate, the outer peripheral side face of the precast top plate and the bent metal plate. Then, concrete is poured into the cavity to achieve the sealed connection of the joint between the upper end face of the precast side plate and the outer peripheral side face of the precast top plate, without the need for additional formwork at the joint between the upper end face of the precast side plate and the outer peripheral side face of the precast top plate, reducing the pouring construction difficulty at the joint position of the two; since the bent metal plate is provided with an expansion part extending outward to the outer side of the joint position between the upper end face of the precast side plate and the corresponding side face of the precast top plate, compared with the concrete cured by formwork pouring at the joint between the upper end face of the precast side plate and the outer peripheral side face of the precast top plate in the traditional construction method, the cross-sectional area of the concrete cured by pouring in the cavity is significantly increased, thereby greatly improving the connection firmness, anti-seepage performance and anti-leakage performance at the joint position between the upper end face of the precast side plate and the outer peripheral side face of the precast top plate. Moreover, the metal bent plate plays a binding role on the concrete cured inside the cavity, effectively avoiding the phenomenon of local corner peeling of the concrete cured inside the cavity, ensuring that the water tank still has good sealing performance during long-term use, thereby extending the maintenance period of the water tank and reducing the operation and maintenance cost, with good economic benefits; the overall structure design is simple, the implementation feasibility is high, and the practicability is strong.

[0006] One of the purposes of the present utility model is to design a connection structure between a precast top plate and a precast side plate of a water tank, which includes a precast top plate and a precast side plate. The side plate steel bar connecting head exposed outside the upper end face of the precast side plate is welded and fixedly connected to the top plate steel bar connecting head exposed outside the corresponding side face of the precast top plate. It also includes a bent metal plate corresponding to the outer side of the joint position between the upper end face of the precast side plate and the corresponding side face of the precast top plate. The bent metal plate includes a vertical edge, an expansion part and a horizontal edge. The vertical edge is fixedly arranged at the lower edge position of the expansion part, and the horizontal edge is fixedly arranged at the upper edge position of the expansion part. The horizontal edge is fixedly installed on the outer side upper end of the precast side plate through a plurality of connecting pieces spaced along its length direction. The expansion part extends outward to the outer side of the joint position between the upper end face of the precast side plate and the corresponding side face of the precast top plate. The horizontal edge extends towards the precast top plate side, and the top plate steel bar connecting head or the side plate steel bar connecting head at the joint position between the upper end face of the precast side plate and the corresponding side face of the precast top plate is fixedly connected to the horizontal edge through a plurality of steel bar connecting sections spaced along the length direction of the horizontal edge. Concrete is poured into the cavity formed by enclosing the upper end face of the precast side plate, the outer peripheral side face of the precast top plate and the bent metal plate.

[0007] A connecting structure between a precast roof slab and a precast side slab of a pool of the present utility model is provided. By arranging a bent metal plate outside the indirect seam position between the upper end face of the precast side slab and the outer peripheral side face of the precast roof slab, a cavity with an upward opening is formed by enclosing the upper end face of the precast side slab, the outer peripheral side face of the precast roof slab, and the bent metal plate. Then, concrete is poured into the cavity to achieve the sealed connection of the seam between the upper end face of the precast side slab and the outer peripheral side face of the precast roof slab, eliminating the need for additional formwork at the seam between the upper end face of the precast side slab and the outer peripheral side face of the precast roof slab, reducing the pouring construction difficulty at the seam position between the two; due to the expansion part provided on the bent metal plate extending outward to the outside of the seam position between the upper end face of the precast side slab and the corresponding side face of the precast roof slab, compared with the concrete solidified by formwork pouring at the seam between the upper end face of the precast side slab and the outer peripheral side face of the precast roof slab in the traditional construction method, the cross-sectional area of the concrete solidified by pouring in the cavity is significantly increased, thus greatly improving the connection firmness, anti-seepage performance, and anti-leakage performance at the seam position between the upper end face of the precast side slab and the outer peripheral side face of the precast roof slab. Moreover, the metal bent plate restricts the concrete solidified inside the cavity, effectively preventing local corner peeling of the concrete solidified inside the cavity, ensuring good sealing performance of the pool during long-term use, thereby extending the maintenance period of the pool and reducing the operation and maintenance cost, with good economic benefits; the overall structure design is simple, the implementation feasibility is high, and the practicability is strong.

[0008] The preferred technical solution is that the expansion part includes an inclined plate section and a vertical plate section. The lower side edge of the vertical plate section is butt-joint fixedly connected to the upper side edge of the inclined plate section, the upper side edge of the vertical side is butt-joint fixedly connected to the lower side edge of the inclined plate section, and the horizontal side is fixedly arranged on the upper side edge of the vertical plate section. The structure design of the expansion part is ingenious and reasonable, effectively increasing the cross-sectional area of the concrete solidified by pouring at the seam between the upper end face of the precast side slab and the outer peripheral side face of the precast roof slab, ensuring the smooth preparation and implementation of the connecting structure of the present utility model.

[0009] A further preferred technical solution is also that the bent metal plate is bent from the same metal plate body. The bent metal plate has good overall consistency and is simple to manufacture and process.

[0010] A further preferred technical solution is also that the butt-jointed ends of the two bent metal plates located at the corner position of the precast roof slab are butt-jointed and welded fixedly together, and the upper end face of the horizontal side is flush with the upper end face of the precast roof slab. Ensuring a cavity with good circumferential sealing performance is formed at the seam position between the outer peripheral side face of the precast roof slab and the upper end faces of the four precast side slabs, thereby effectively avoiding a large amount of concrete overflow when pouring concrete into the cavity, with good economic benefits.

[0011] Preferably, in another technical solution, one end of the steel bar connecting section is fixedly connected to the corresponding top plate steel bar connector or side plate steel bar connector by welding, and the other end of the steel bar connecting section is fixedly connected to the lower side surface of the horizontal edge by welding. The horizontal edge is fixedly connected to the corresponding top plate steel bar connector or side plate steel bar connector through the steel bar connecting section by welding.

[0013] Preferably, in another technical solution, the precast top plate is formed by splicing a plurality of precast top plate units, and the precast side plate is formed by splicing a plurality of precast side plate units.

[0014] For the second object of the present utility model, a prefabricated water tank is designed, including a precast top plate, a precast side plate and a bottom plate. The lower end of the precast side plate is poured into a side plate installation groove reserved on the upper end surface of the bottom plate, and the outer peripheral side surface of the precast top plate and the upper end surface of the precast side plate are fixedly connected together through the connection structure between the precast top plate and the precast side plate of the water tank described above.

[0015] In a prefabricated water tank of the present utility model, a cavity with an upward opening is formed by enclosing a bent metal plate at the joint position between the outer peripheral side surface of the precast top plate and the upper end surface of the precast side plate, and concrete is poured into the cavity and sealed together after curing. Compared with the traditional method of pouring concrete with formwork, the cross-sectional area of the cured concrete at the joint position is significantly increased, thereby greatly improving the connection firmness, anti-seepage performance and anti-leakage performance at the joint position between the upper end surface of the precast side plate and the outer peripheral side surface of the precast top plate. Moreover, the bent metal plate plays a binding role on the concrete cured inside the cavity, effectively preventing the local corner peeling of the concrete cured inside the cavity, ensuring that the water tank still has good sealing performance during long-term use, thereby extending the maintenance period of the water tank and reducing the operation and maintenance cost, with good economic benefits.

By arranging a bent metal plate on the outer side of the joint position between the upper end face of the precast side wall and the outer peripheral side face of the precast roof slab, a cavity with an upward opening is formed by enclosing the upper end face of the precast side wall, the outer peripheral side face of the precast roof slab and the bent metal plate. Then, concrete is poured into the cavity to achieve the sealed connection of the joint between the upper end face of the precast side wall and the outer peripheral side face of the precast roof slab, without the need for additional formwork at the joint between the upper end face of the precast side wall and the outer peripheral side face of the precast roof slab, reducing the pouring construction difficulty at the joint position of the two; since the bent metal plate is provided with an expansion part extending outward from the joint position between the upper end face of the precast side wall and the side face corresponding to the precast roof slab, compared with the concrete cured by formwork pouring at the joint between the upper end face of the precast side wall and the outer peripheral side face of the precast roof slab in the traditional construction method, the cross-sectional area of the concrete cured by pouring in the cavity is significantly increased, thus greatly improving the connection firmness, anti-seepage performance and anti-leakage performance at the joint position between the upper end face of the precast side wall and the outer peripheral side face of the precast roof slab, and the metal bent plate plays a binding role on the concrete cured inside the cavity, effectively avoiding the phenomenon of local corner peeling of the concrete cured inside the cavity, ensuring that the pool still has good sealing performance during long-term use, thereby extending the maintenance period of the pool and reducing the operation and maintenance cost, with good economic benefits; the overall structure design is simple, the implementation feasibility is high, and the practicability is strong.

[0040] Construction principle of an assembled water tank in Embodiment 2:

[0041] Step 1: Excavate the foundation, confirm the elevation and flatness of the foundation surface, pour the bottom plate 6, and reserve a side slab installation groove on the outer peripheral side of the upper end surface of the bottom plate 6;

[0042] Step 2: After the bottom plate 6 is cured, hoist a plurality of side slab units into the side slab installation groove on the upper end surface of the bottom plate 6 in sequence. The vertical surfaces between two adjacent side slab units are fixedly connected by butt welding of exposed steel bar connectors. Then, the joints between the vertical surfaces of the two precast side slab units are sealed and connected by a sealing component, or sealed and connected by pouring cement mortar to form the precast side slab 2. Finally, pour concrete into the side slab installation groove to fix the lower end of the precast side slab 2 in the side slab installation groove on the upper end surface of the bottom plate 6;

[0043] Step 3: Lay a tension bar assembly and support columns inside the frame structure formed by the precast side slab 2 and the bottom plate 6.

Then, the joints between the vertical surfaces of the two precast roof slab units are sealed and connected by a sealing component, or sealed and connected by pouring cement mortar to form the precast roof slab 1;

[0044] Step 4: Fix the four bent metal plates 3 to the upper ends of the outer sides of the four precast side plates 2 of the pool respectively by self-tapping screws passing through the vertical sides 3-1 at several intervals. The bent metal plates 3 are located outside the seam positions on the corresponding sides between the upper end faces of the precast side plates 2 and the precast top plate 1. The butt ends of the two bent metal plates 3 at the corner positions of the precast top plate 1 are butted and spliced and then welded and fixedly connected together.
