[0041] like Figure 1-13 As shown, the first aspect of this application provides a water tank structure with anti-cracking composite wall panels. This anti-cracking composite wall panel water tank structure includes multiple composite slab base plates 1, multiple permanent formworks 3, and a reinforced concrete layer 4. The multiple composite slab base plates 1 are connected by bolts 2. Each composite slab base plate 1 includes an ultra-high toughness concrete slab 11, located on one side of the composite slab base plate 1 along its thickness direction. The multiple permanent formworks 3 are connected one-to-one with the multiple composite slab base plates 1. Each permanent formwork 3 includes a steel formwork 31 and an insulation layer 30, located on the side of the steel formwork 31 away from the ultra-high toughness concrete slab 11. A cavity exists between the steel formwork 31 and the ultra-high toughness concrete slab 11. The reinforced concrete layer 4 is at least partially disposed within the cavity between the steel formwork 31 and the ultra-high toughness concrete slab 11.

[0042] In this embodiment, the water tank structure with anti-cracking composite wall panel forms the first anti-cracking defense line through ultra-high toughness concrete slab 11. Ultra-high toughness concrete can fully utilize the tensile strength and energy absorption capacity of the concrete. The reinforced concrete layer 4 is set between the steel formwork 31 and the ultra-high toughness concrete slab 11 to form the second anti-cracking defense line. The steel formwork 31 of the permanent formwork 3 and the insulation layer 30 are arranged on the outside to form the third anti-cracking defense line. The steel formwork 31 can bring greater rigidity and load-bearing capacity to the structure, and the insulation board can effectively provide insulation for the water tank. Thus, the water tank structure with anti-cracking composite wall panel has a better anti-cracking effect, thereby improving the usability, safety and durability of the water tank.

[0043] like Figure 2-6As shown, in one specific embodiment, the composite plate base plate 1 further includes a first flange plate 12 and a first web plate 13. The first flange plate 12 is located on opposite sides of the composite plate base plate 1 along the length direction, and the first web plate 13 is located on opposite sides of the composite plate base plate 1 along the width direction. The first flange plate 12 has a first connecting portion, and the first web plate 13 has a second connecting portion. Specifically, the first connecting portion includes a first through groove 14 and a plurality of first through holes 15, the first through groove 14 and the first through holes 15 being respectively disposed on opposite sides of the first flange plate 12; the second connecting portion includes a second through groove 16 and a plurality of second through holes 17, the second through groove 16 being disposed on at least one side of the first web plate 13, and / or the second through holes 17 being disposed on at least one side of the first web plate 13.

[0044] In this embodiment, the first flange plate 12 and the first web plate 13 of the composite slab bottom plate 1 are made of steel plates. The first through slot 14, the second through slot 16, the first through hole 15 and the second through hole 17 can all serve one or more of the following functions during assembly: bolts 2 pass through for fixing, steel mesh 41 in the reinforced concrete layer 4 passes through, connect with the permanent formwork 3, and serve as a flow channel for cast-in-place concrete. The specific function depends on the position of the first through slot 14, the second through slot 16, the first through hole 15 and the second through hole 17. For example, the first through slot 14 can simultaneously serve three functions: allowing steel mesh 41 to pass through, connecting with the permanent formwork 3 and serving as a flow channel for cast-in-place concrete. This is not specifically limited in this article.

[0045] The ultra-high toughness concrete slab 11 is cast from ultra-high toughness cement-based composite material and fixedly installed within the composite slab base plate 1. Ultra-high toughness cement-based composite material possesses excellent toughness and energy absorption capacity. The ultimate tensile strain of ultra-high toughness concrete can reach 3%~6%, far exceeding the 0.01% of ordinary concrete and even surpassing the 0.15% of ultra-high performance concrete. Using ultra-high toughness concrete for the base plate of the composite wall panel can significantly improve the crack resistance of the wall panel, and ultra-high toughness concrete can also absorb some of the energy generated during water sloshing.

[0046] like Figure 7-13As shown, in one specific embodiment, the permanent template 3 further includes a second flange plate 32 and a second web plate 33. The second flange plate 32 is located on at least one side of the permanent template 3 along its length, and the second web plate 33 is located on opposite sides of the permanent template 3 along its width. The second flange plate 32 has a third connecting portion, and the second web plate 33 has a fourth connecting portion. At least one of the third and fourth connecting portions can be connected to at least one of the first and second connecting portions. Specifically, the third connecting portion includes a U-groove clip and a plurality of third through holes 35. The U-groove clip can be connected or snapped into the first connecting portion. The fourth connecting portion includes a flange clip 36, or the fourth connecting portion includes a flange clip 36 and a plurality of fourth through holes 37. The flange clip 36 can be connected or snapped into the second connecting portion. This splicing method enables rapid assembly and connection and fixation of the composite slab base plate 1 and the permanent template 3. The composite slab base plate 1 and the permanent template 3 can be assembled and constructed. Even if concrete is poured on site, there is no need for additional formwork on site, truly realizing green construction.

[0047] In this embodiment, the second flange plate 32 and the second web plate 33 of the permanent template 3 correspond to the first flange plate 12 and the first web plate 13 of the composite plate base plate 1, respectively. The second flange plate 32 and the second web plate 33 can also be steel plates. The third through hole 35 and the fourth through hole 37 on the second flange plate 32 can be used for bolts 2 to pass through. The U-groove clip is embedded in the first flange plate 12 of the composite plate base plate 1. In addition, the second web plate 33 is provided with a cover plate web plate on the side to ensure the sealing. The flange clip 36 is embedded in the first web plate 13 of the composite plate base plate 1, and alternately engages with the second web plate 33 of the adjacent permanent template 3.

[0048] In this embodiment, the steel formwork 31 and the insulation board are used to form a permanent formwork 3. Connecting clips are installed on the permanent formwork 3. After the composite slab base plate 1 is assembled and the reinforcing bars are drilled, the permanent formwork 3 is fixed to the composite slab base plate 1 using the connecting clips, which avoids the on-site formwork construction procedure for concrete pouring. The insulation board is placed on the outside of the permanent formwork 3, which can also prevent excessive temperature difference and provide insulation for the water tank structure.

[0049] In this embodiment, the composite slab base plate 1 is made of ultra-high toughness concrete, and the permanent formwork 3 includes a steel formwork 31 with insulation board. Both are equipped with flanges and webs around their perimeter, and the flanges and webs have quick-assembly features. Bolts 2 and reinforcing bars pass through channels for easy and rapid installation and fixing. The composite slab, the permanent formwork 3, and the intermediate cavity formed by the two constitute three lines of defense against cracking, ensuring the crack resistance of the pool structure.

[0050] like Figure 1As shown, in one specific embodiment, the reinforced concrete layer 4 includes a steel mesh 41 and concrete. The steel mesh 41 is arranged in a crisscross pattern and passes through multiple composite slab bottom plates 1. The concrete is poured into the cavity between the steel formwork 31 and the ultra-high toughness concrete slab 11.

[0051] The second aspect of this application provides a construction method for a crack-resistant composite wall panel water tank structure, which mainly includes the following steps:

[0052] Assembling the composite plate base plate 1: Align the first flange plate 12 and the first web plate 13 of the multiple composite plate base plates 1 respectively, and splice the multiple composite plate base plates 1 with bolts 2;

[0053] Arrangement of steel mesh 41: Horizontal steel bars are passed through the first web 13 and vertical steel bars are passed through the first flange 12. The horizontal and vertical steel bars are fixed at the intersection by binding or welding.

[0054] Erection of permanent template 3: Align and embed the U-groove clips on permanent template 3 into the first flange plate 12 of the composite plate base plate 1, and align and embed the flange clips 36 on permanent template 3 into the first web plate 13 of the composite plate base plate 1.

[0055] Concrete pouring: Concrete is poured between the composite slab base plate 1 and the permanent formwork 3 to form a complete anti-cracking composite wall panel water tank structure.

[0056] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
