[0014] In the joint structure of the assembled integral water pool of the laminated plate structure disclosed in the present application, the bottom end of the prefabricated wall panel expands toward both sides of the groove to form an enlarged end;

[0015] The expanded thickness of the enlarged end is not less than the thickness of the prefabricated wall panel;

[0016] A third cavity is formed between the enlarged ends on both sides of the groove, and the width of the third cavity is equal to the groove width of the groove.

[0017] In the joint structure of the assembled integral water pool of the laminated plate structure disclosed in the present application, the horizontal joint structure includes bidirectional stress-bearing steel bars arranged in the prefabricated wall panels;

[0018] The horizontal stressed steel bars are provided with reinforcements on both sides, and the vertical stressed steel bars are provided with reinforcements on the bottom side, extending through the third cavity to the bottom of the groove and bending toward the middle of the groove.

[0019] In the joint structure of the assembled integral pool of the composite plate structure disclosed in the present application, the side of the prefabricated wall plate close to the groove is a rough surface, and the side away from the groove is a smooth plane;

[0020] The rough surface is provided with ribs at equal intervals, the ribs are arranged horizontally or / and vertically, and the vertical edges of both sides of the prefabricated wall panel are non-rib plate portions;

[0058] See also Figures 1 to 7 As shown, the embodiment of the present application provides a joint structure of an assembled integral water pool with a superimposed plate structure, the main purpose of which is to solve the problems that there are too many joints in the wall of the existing water pool, the construction at the joints is inconvenient, the joints often have a small amount of cast-in-place, and are weak areas for stress and waterproofing of the assembled water pool, and the construction quality is difficult to guarantee.

[0059] The present application discloses a joint structure of an assembled integral pool of a laminated plate structure, comprising a bottom plate 1 and a laminated wall plate 2. The bottom plate 1 is used to form the bottom of the pool, and can be a cast-in-place or prefabricated bottom plate. The laminated wall plate 2 is used to form the pool wall of the pool, and is formed by laminating prefabricated pool wall components.

[0060] See also Figure 1As shown, a plurality of superimposed wall panels 2 are arranged on the bottom plate 1, and the superimposed wall panels 2 are connected to each other to form a "I"-shaped structure, an "L"-shaped structure, and a "T"-shaped structure, and the "I"-shaped structure, "L"-shaped structure, and "T"-shaped structure are connected to each other to form the pool wall. Pools of different shapes can be assembled with the "I"-shaped structure, "L"-shaped structure, "T"-shaped structure and the bottom plate 1. Figure 1 As shown, the "I"-shaped structure, the "L"-shaped structure, and the "T"-shaped structure are interconnected and form a "double-grid water pool" with the bottom plate 1.

[0061] The composite wall panel 2 is formed by stacking two prefabricated wall panels 21. The prefabricated wall panel 21 is a prefabricated pool wall component. At present, the prefabricated pool wall components similar to double-skin walls (only used as casting templates, not involved in force) are in the form of "two pieces in one", that is, the wall panels on both sides of the same pool wall are fixed into a whole by rack steel bars or truss angle steels in the factory to form the composite wall panel 2. It is heavy and inconvenient to transport, resulting in heavy lifting of the physical assembled components.

[0062] Taking into account the existing component production level and the important hoisting factors in prefabricated construction, the present application produces the composite wall panel 2 as two prefabricated wall panels 21, which are not fixed with truss angles. The two prefabricated wall panels 21 are separately hoisted and fixed on site to form the composite wall panel 2. The fixing process of the two prefabricated wall panels 21 is moved from the production stage to the construction stage, which is convenient for production, transportation and installation.

[0063] The production specifications of the prefabricated wall panels 21 are consistent, in line with the principle of modularization, low in cost and high in efficiency. The prefabricated wall panels 21 are simple in form, feasible to manufacture, and have a high prefabrication ratio, which can give full play to the advantages of standardized mass production. The weight of the single-piece prefabricated wall panels 21 is at least half that of the composite wall panels 2, and for prefabricated components of the same weight, the single-piece prefabricated wall panels 21 can be larger and thicker, which can break through the hoisting restrictions or reduce the number of joints. As an important component of the pool wall, the composite wall panels 2 give full play to their bearing capacity.

[0064] See also Figure 6 As shown, a first cavity 25 is formed between the two prefabricated wall panels 21, and a groove 3 is provided on the bottom plate 1 below the first cavity 25. Considering the actual construction operation effect and the requirements of the process design for the complex shape of the bottom plate 1, the bottom plate 1 of the present application adopts a cast-in-place mode, and is partially thickened and provided with a groove 3 according to an adapted shape. A water stop strip (plate) 31 is provided at the bottom of the groove 3 to enhance the water stopping ability of this position.

[0065] The composite wall panels 2 are connected to the bottom plate 1 through a horizontal joint structure, and the composite wall panels 2 are connected to each other through a vertical joint structure. Concrete is poured between the prefabricated wall panels 21 and the grooves 3. Considering that the corner of the pool is a key part, the post-casting belt type integral joint is used at the joint position to ensure its integrity and reliably and continuously transmit force. The post-casting belt type joint is open, which is convenient for operating steel bars, etc., and avoids the problem of inconvenient operation of the close-fitting type.

[0066] A groove 3 is provided on the bottom plate 1, and the groove 3 moves the construction joint of the pool wall downward, and moves the bonding surface of the new and old concrete downward to the bottom of the groove 3, avoiding the most unfavorable stress position, and having a certain embedding effect on the pool wall.

[0067] The present application effectively eliminates weak links in stress or waterproofing through the "prefabricated + cast-in-place" assembled integral form. Through the assembly of single-piece prefabricated wall panels 21, it is convenient to replace the single-piece prefabricated wall panels 21 with cast-in-place templates at individual positions of the pool wall, thereby realizing the complex structural modeling required by the treatment process. The local shape and form of the pool can be flexibly adjusted, and the post-poured concrete can ensure its integrity, and can reliably and continuously transmit force, ensuring that the waterproofing and stress-bearing effects during the operation period can be well achieved.

[0068] This application comprehensively considers various factors and selects a composite wall panel 2 that is more suitable for the pool wall according to the characteristics of the pool project. A single-piece prefabricated wall panel 21 with a suitable shape is designed, which is combined into a double wall on site to form a first cavity 25. Concrete is then poured to form the pool wall. The prefabrication rate of the pool wall is above 50%, which is a high prefabrication rate component (prefabrication ratio 50%~70%).

[0069] In one embodiment, the vertical joint structure has an "I"-shaped additional steel cage 41, an "L"-shaped additional steel cage 42, and a "T"-shaped additional steel cage 43. Figure 2 As shown, the "L"-shaped additional steel cage 42 is arranged at the corner connection of the "L"-shaped structure, the "I"-shaped additional steel cage 41 is arranged at the connection of two superimposed wall panels 2 of the "I"-shaped structure, and the "T"-shaped additional steel cage 43 is arranged at the connection of three superimposed wall panels 2 of the "T"-shaped structure. The "L"-shaped additional steel cage 42, the "I"-shaped additional steel cage 41, and the "T"-shaped additional steel cage 43 are all prefabricated components, which are adapted to the joint nodes of the "I"-shaped structure, the "L"-shaped structure, and the "T"-shaped structure formed by the superimposed wall panels 2 connected to each other, which can reduce the types and specifications of components and conform to the principle of modular assembly.

[0070] According to the principle of fewer specifications and more combinations, the present application combines the prefabricated wall panels 21 and three additional steel cages 4 into one specification, or even into one size, and then combines them with cast-in-place to form different parts of the pool. This is conducive to factory modular production and avoids the frequent mold changes of the diversified composite wall panels 2, which reduces production efficiency and increases production costs.

[0071] In one embodiment, see Figures 2~5 As shown, the "L"-shaped additional steel cage 42, the "I"-shaped additional steel cage 41, and the "T"-shaped additional steel cage 43 are all provided with a second cavity 44, and the second cavity 44 is used to pour concrete to form a hidden column of the pool. The additional steel cage 4 mainly plays a reinforcing role. The shape of the steel bars is adapted to the connection shape of the composite wall panel 2. The additional steel cage 4 is designed to be shape-adaptive, further enhancing the bearing capacity of this area and ensuring reliable connection at the joint.

[0072] In one embodiment, see Figure 6 As shown, the bottom end of the prefabricated wall panel 21 expands toward both sides of the groove 3 to form an enlarged end 26. A gasket is used between the lower end of the enlarged end 26 and the bottom plate 1 for leveling. The gasket can be made of steel or even paper to level the elevation and adjust the linearity of the wall. The enlarged end 26 is in the shape of a flat folded plate or an oblique axillar angle to form a form of a larger bottom and a smaller top, which enhances the ability of the pool wall to resist the out-of-plane bending moment at the most unfavorable part of the force, so that the center of gravity of the composite wall panel 2 is biased toward the center of the internal pool wall, which is conducive to fixing and installation during the construction process and is conducive to maintaining stability under unfavorable working conditions such as pouring concrete.

[0073] The expanded thickness of the enlarged end 26 is not less than the thickness of the prefabricated wall panel 21, and a third cavity 27 is formed between the enlarged ends 26 on both sides of the groove 3, and the width of the third cavity 27 is equal to the groove width of the groove 3. The prefabricated wall panel 21 is a tall template with a large deadweight, which is more advantageous in resisting overturning. The lower part is the enlarged end 26, and the center of gravity of the composite panels on both sides is biased toward the center of the internal pool wall, which is conducive to maintaining stability under adverse working conditions such as pouring concrete.

[0074] In one embodiment, a top plate (not shown in the figure) is provided above the water pool. The horizontal joint between the top of the water pool and the top plate can be set in the form of a conventional shear wall top. Prefabricated wall panels 21 are arranged according to the upper beam and slab layout. An additional steel cage 4 in the form of a hidden beam can be arranged in the top cavity to strengthen the node structure.

[0075] In one embodiment, see Figure 6 , 7As shown, the horizontal joint structure includes bidirectional stress-bearing steel bars 5 arranged on the prefabricated wall panels 21. The stress-bearing steel bars 51 in the horizontal direction have bars on both sides, so that the composite wall panels 2 can be connected to each other by mechanical connection or the like. The stress-bearing steel bars 52 in the vertical direction have bars on the bottom side, pass through the third cavity 27, extend to the bottom of the groove 3, and bend toward the middle of the groove 3.

[0076] Specifically, at the position of the enlarged end 26, the vertical stress-bearing steel bars 52, as the main stress-bearing steel bars, are exposed inside the third cavity 27, and are later combined with the post-cast concrete in the third cavity 27 to form a whole, achieving the effect of integral casting without leaving construction joints.

[0077] Specifically, the prefabricated wall panel 21 is provided with a single layer of bidirectional stress-bearing steel bars 5, and the spacing of the steel bars in each part is uniform, and the diameter of the steel bars can be modified according to the actual stress. Unlike the conventional pool component in which the vertical stress-bearing steel bars 52 are arranged on the outside of the horizontal stress-bearing steel bars 51 (away from the side of the groove 3), the horizontal stress-bearing steel bars 51 of the prefabricated wall panel 21 are arranged on the outside.

[0078] In one embodiment, see Figure 7 As shown, the side of the prefabricated wall panel 21 close to the groove 3 is a rough surface 22, and the side away from the groove 3 is a smooth plane 23. Two prefabricated wall panels 21 are hoisted and fixed on site to form a composite wall panel 2, and the rough surface 22 is the bonding surface of the two prefabricated wall panels 21, and the rough surface 22 can increase the bite effect. The outer side of the prefabricated wall panel 21 is a smooth plane 23, and the inner side is a rough surface 22, which is conducive to the joint bearing of the prefabricated part and the cast-in-place part and coordinated force.

[0079] Among them, a waterproof layer is arranged on the smooth plane 23. The outer side of the composite wall panel 2 is a smooth plane 23. When the prefabricated wall panel 21 is produced, its smooth plane 23 is used as a waterproof layer, which can improve the waterproof quality and save the on-site construction period.

[0080] Specifically, see Figure 7 As shown, ribs 24 are arranged at equal intervals on the rough surface 22, and the ribs 24 are arranged horizontally or / and vertically. The ribs 24 can be arranged horizontally, vertically, or bidirectionally, and the ribs 24 enhance the bite and bonding effect of the bonding surface.

[0081] In order to simplify the production of the prefabricated wall panel 21, no ribs 24 are provided at the expanded end 26, and the inner side is in a flat form with only a rough surface 22 provided.

[0082] The vertical edges of the prefabricated wall panels 21 are flat plate portions without ribs 24, that is, the vertical edges of the prefabricated wall panels 21 are not provided with ribs 24. The vertical edges of the prefabricated wall panels 21 are the joints of the composite wall panels 2, and the joints are flat plate portions, which can form a casting cavity with a larger plane size, ensuring the effective cross-sectional height of the cast-in-place pool wall in the joint area. After casting, the pool wall is firmly combined, and the integrity of the component is stronger.

[0083] In one embodiment, see Figure 6 As shown, bidirectional structural steel bars 6 are arranged on the ribs 24. Among them, the horizontal structural steel bars 61 are exposed in the non-rib 24 part, and the two ends thereof are connected to the vertical joint structure. The vertical structural steel bars 62 are provided at the bottom and extend into the third cavity 27. The horizontal structural steel bars 61 of the prefabricated wall panel 21 are located on the outside of the vertical structural steel bars 62 (away from the side of the groove 3). The structural steel bars play a role in strengthening the rigidity of the component during transportation and installation, and play a role in pin shear resistance after pouring concrete, thereby enhancing the integrity of the component. The structural steel bars can be provided on the side for anchoring according to the stress performance requirements of the component, and can also serve as stress-bearing steel bars.

[0084] See also Figure 6 , 7 As shown, the spacing between the bidirectional force-bearing steel bars 5 and the bidirectional structural steel bars 6 is the same, the ribs 24 are vertically arranged on the rough surface 22, the horizontal structural steel bars 61 are exposed outside the non-rib 24 part, and the vertical structural steel bars 62 are arranged inside the ribs 24, with the bottom side of the steel bars extending into the third cavity 27. The bidirectional force-bearing steel bars 5 are prestressed steel bars or prestressed steel strands, and the bidirectional structural steel bars 6 are truss steel bars. If the single-piece prefabricated wall panel 21 is considered for the purpose of saving materials and reducing weight, and if it is desired to achieve a larger bearing capacity with a smaller component size, it can be considered to be made into a prefabricated prestressed reinforced concrete component.

[0085] In one embodiment, see Figure 6 As shown, the bottom of the groove 3 is pre-buried with vertical additional steel bars 32. The vertical additional steel bars 32 are rectangular ring-shaped, with the lower end buried in the bottom of the groove 3, and the upper end is staggered with the vertical force steel bars 52 and the vertical structural steel bars 62. A rectangular ring-shaped vertical additional steel bar 32 is reserved inside the groove 3, and the bearing capacity of this area is improved by adding local steel bars.

[0086] Specifically, see Figure 6 As shown, the height of the space formed by the third cavity and the groove is greater than the height of the weak area of ​​force and waterproofing at the bottom of the pool wall. The height of the vertical additional steel bars is adapted to the height of the space to enhance the connection strength between the bottom plate 1 and the composite wall plate 2. According to the cast-in-place specification, the distance 300-500 above the top elevation of the bottom plate is not allowed to leave a construction joint, which is a weak area of ​​force and waterproofing.

[0087] In one embodiment, see Figures 3-5 As shown, the additional steel cage 4 has vertical steel bars 46 and horizontal steel bars 45, and the additional steel cage 4 is used to strengthen the horizontal force-bearing steel bars 51 and the horizontal structural steel bars 61 of the prefabricated wall panel 21. The vertical steel bars 46 serve as the steel cage skeleton, and the horizontal steel bars 45 are enclosed on the vertical steel bars 46 to form a second cavity 44. Specifically, the horizontal steel bars 45 of the "I"-shaped additional steel cage 41 are changed from the conventional ring shape to an "8-shaped" shape, the horizontal steel bars 45 of the "L"-shaped additional steel cage 42 are "L-shaped", and the horizontal steel bars 45 of the "T"-shaped additional steel cage 43 are "T-shaped", which are respectively adapted to the "I"-shaped structure, the "L"-shaped structure, and the "T"-shaped structure.

[0088] When assembling the assembled integral pool of the present application, the prefabricated wall panels 21 on the inner side of the pool wall are first installed, and the additional steel cage 4 is added during the process, and then the outer prefabricated wall panels 21 are installed for sealing, and finally concrete is poured to eliminate the weak area. Alternatively, the additional steel cage 4 is added first, and then the prefabricated wall panels 21 on both sides are installed.

[0089] In a specific implementation scenario, take the "double-grid water pool" as an example, see Figure 1 , 2 As shown, the main body of the pool wall adopts the form of "superimposed wall panels on both sides + cast-in-place in the middle cavity". The joints are weak areas, and the form of "cast-in-place nodes + reinforced steel structure" is adopted. A series of structural measures are taken to enhance the integrity of the components and eliminate weak areas. The bottom plate 1 is prefabricated or cast-in-place, and is partially thickened and provided with grooves 3 according to the adapted shape. The prefabricated wall panel 21 is a prefabricated pool wall component. The inner prefabricated wall panel 21 is installed on site first, and the steel cage 4 is attached, and then the outer prefabricated wall panel 21 is installed to form a prefabricated partial system.

[0090] Considering factors such as production, transportation, and installation, the width of the prefabricated wall panel 21 can be 1.5m, 1.8m, 2.1m, and 2.4m, the height should not be greater than 7m, and the total weight should not be greater than 3.5t. To reduce joints, the width should be larger rather than smaller while meeting various conditions.

[0091] The plate thickness of the prefabricated wall panel 21 should not be less than 100mm, and the thickness of the ribs 24 on the rough surface 22 should not be less than 80mm. The minimum net width of the first cavity 25 formed after the two prefabricated wall panels 21 are installed should not be less than 1.3 times the plate thickness, and should not be less than 150mm. Taking the pool wall thickness of 700mm as an example, the thickness of the flat plate part of the prefabricated wall panel 21 is 150mm, the thickness of the locally protruding ribs 24 is 100mm, and the minimum net width of the first cavity 25 is 200mm. The thickness of the rough surface 22 is not less than 6mm to increase the bite between the composite wall panel 2 and the cast-in-place concrete aggregate.

[0092] The starting point of the vertical stress-bearing steel bar 52 is 300 mm to 500 mm above the bottom of the prefabricated wall panel 21. The distance from the outer side of the vertical stress-bearing steel bar 52 to the smooth plane 23 is not less than 50 mm.

[0093] The vertical structural steel bar 62 is embedded in the rib 24, and the protective layer on the inner surface thereof shall not be less than 15 mm. The diameter of the structural steel bar shall not be less than 8 mm.

[0094] When installing the composite wall panel 2, the bottom plate 1 is used to bolt the connector 7, the oblique support 8 and the limit rod 9. The bottom bolted connector 7 is fixed by the anchor bolts of the bottom plate 1 and the pre-buried expansion bolts on the prefabricated plate. The composite wall panel 2 uses the oblique support 8 to support the pool wall. The tops of the two prefabricated wall panels 21 of the composite wall panel 2 are connected by the limit rod 9. Channel steels 92 are provided at both ends of the limit rod 9. The top of the prefabricated wall panel 21 is provided with a slot in the form of the channel steel 92. The opening of the channel steel 92 is set downward and buckled on the slot to achieve the purpose of limiting the relative displacement of the two prefabricated wall panels 21. The position of the channel steels 92 on both sides of the slot support can be adjusted according to the elevation of the top of the composite panels on both sides.

[0095] Based on the above embodiments, the joint structure of the assembled integral pool of the laminated plate structure according to the embodiment of the present invention has the following advantages:

[0096] The pool wall of the present application is composed of composite wall panels 2, which are composed of two prefabricated wall panels 21. The shape, stress-bearing steel bars and structural steel bars of the composite wall panels 2 are innovated. During the on-site installation of the composite wall panels 2, additional steel cages 4 are set at the connections, and the installed and fixed components form a cavity with a certain space in the middle. Concrete is poured in the cavity, and vertical and horizontal seam connections are made. Then, the cavity is connected with the post-poured concrete to form an integral stress-bearing pool wall to ensure the integrity of the components.

[0097] In this application, two prefabricated wall panels 21 are installed on site as an integrated double-sided laminated wall panel 2. Among the pool walls of the same size, this form has the lightest deadweight, which can break through the hoisting restrictions or reduce the number of joints. The laminated wall panel 2, as an important component of the pool wall, gives full play to its bearing capacity. Moreover, for prefabricated pool wall components of the same weight, a single prefabricated wall panel 21 can be made larger and longer, reducing the number of joints, which is more conducive to production, transportation and installation.

[0098] In this application, weak areas such as horizontal joints and vertical joints of the water pool are adjusted or strengthened through component shape or steel bar structure. The joint position takes into account the characteristics of the water pool, leaving a large cavity to ensure the proportion of cast-in-place concrete. The structure is simple and the force transmission is reliable, which can effectively eliminate weak links in force or waterproofing.

[0099] This application takes into account the characteristics of the pool structure, comprehensively considers all aspects such as design, production, construction and use, selects a reasonable assembly method, and conducts adaptive improvement and optimization. It mainly studies the application of assembly technology in thick-sized pool wall components, and focuses on the innovation of prefabricated parts and joint connection structures to form an assembled integral pool system with reasonable design, feasible production, convenient construction and strong practicality.

[0100] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
