Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to an assembled rectangular pool. Background Art

[0002] The traditional full cast-in-place technology is generally used in water pool construction, but there are several problems with the cast-in-place model: the construction quality is difficult to control, and leakage has become a common problem in the industry; the construction work surface requires a large amount of space, which wastes resources and materials and is not conducive to environmental protection; the construction period is long, and it is difficult to meet the urgent need for sewage treatment; the working environment on the construction site is poor, and there is a shortage of labor. Therefore, the prefabricated technology is applied to reinforced concrete water pool structures to solve the above problems.

[0003] The prefabricated components of the existing prefabricated pool technology have many specifications after being disassembled, which does not conform to the principles of modularization and standardization. The pool wall is generally a prefabricated component in the form of a flat plate, and the horizontal joint is set at the most unfavorable position on the top of the bottom plate, resulting in local weakness and not meeting the requirements of the specification to set a horizontal construction joint at a position above 300~500mm on the top of the bottom plate. The bottom plate of the pool is generally prefabricated and cast-in-place. The contact surface between the bottom plate of the prefabricated component and the lower rigid cushion layer is difficult to effectively fit, resulting in gaps and stress concentration; the cast-in-place bottom plate has good integrity and coordination, but it increases a large number of on-site wet operations and reduces the prefabrication rate.

[0004] The existing technical solutions for prefabricated pools generally use wet connection for the joints, that is, the joints are poured with concrete after the steel bars are connected. The specification requires the percentage of steel bar joints in the same connection section. In order to increase the prefabrication rate and reduce the difficulty of formwork, the prefabricated pool has a smaller cavity at the joints, resulting in the steel bar joints being located in the same section, which does not meet the requirements of the specification. The flat end surface of the prefabricated components at the joints has a poor waterproof effect. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present application provides an assembled rectangular pool, which fully considers the force principles of various parts of the pool and tries to merge the prefabricated components in different parts. For example, the horizontal corner bending moment at the corner is large, and the vertical bending moment at the bottom of the pool is large. The forces at these two parts are similar and both are unfavorable parts. The components can be merged into an L-shaped prefabricated component; the upper part of the pool wall and the middle part of the pool bottom are similar in size and simple in form, and can be merged into a flat plate prefabricated component; the present application reasonably divides the rectangular pool into L-shaped prefabricated components and flat plate prefabricated components. The combination of the two can flexibly realize pool structures of various sizes, reduce the types of prefabricated components, unify the same specifications and sizes, and realize larger-scale and more forms of assembled pools with fewer specifications and simple forms of prefabricated components.

[0006] The technical solution adopted by the present invention is:

[0010] The joints of the L-shaped prefabricated components and the flat prefabricated components are integral joints in the form of post-cast strips. In the assembled rectangular pool disclosed in the present application, a plurality of I-beams are arranged below the L-shaped prefabricated components at the four corners of the pool wall, and a plurality of pads are arranged on the lower bottom surface of the pool bottom;

[0011] A casting space is formed between the I-beam, the cushion block and the lower bottom surface of the pool bottom, and concrete is cast in the casting space to form a cushion layer.

[0012] In the assembled rectangular pool disclosed in the present application, when the pool wall height of the rectangular pool needs to be increased, an additional pool wall is arranged above the pool wall;

[0013] The additional pool wall is composed of the L-shaped prefabricated components and the flat plate prefabricated components;

[0014] Among them, the two flat plates of the four L-shaped prefabricated components are arranged vertically to form the four corners of the additional pool wall. The flat plate prefabricated components are arranged vertically and are connected with the four L-shaped prefabricated components through seams to form the additional pool wall.

[0015] In the assembled rectangular pool disclosed in the present application, the L-shaped side surfaces on both sides of the L-shaped prefabricated component are provided with tooth grooves along the length direction of the flat plate;

[0016] Among them, one flat plate is provided with tooth grooves starting from convex teeth, and the other flat plate is provided with tooth grooves starting from concave grooves; when the L-shaped side surfaces of the two L-shaped prefabricated components are connected to each other, the convex teeth correspond to the concave grooves at the joints.

[0017] In the assembled rectangular pool disclosed in the present application, long protruding teeth are arranged at both ends of one end surface of the flat plate prefabricated component, and tooth grooves are arranged on the other three end surfaces;

[0018] The teeth and grooves on the opposite side end surfaces of the flat plate prefabricated components are arranged in a staggered manner, that is, the convex teeth on one side correspond to the concave grooves on the other side; when two flat plate prefabricated components are connected, the convex teeth correspond to the concave grooves at the joint.

[0019] In the assembled rectangular pool disclosed in the present application, the L-shaped prefabricated components and the flat prefabricated components are provided with steel bars inside, and the four end faces thereof are all provided with steel bars, wherein the reinforcement point of one end face of the tooth groove is the middle position of the convex teeth and the concave groove.

[0020] In the assembled rectangular water pool disclosed in the present application, when the flat prefabricated component is arranged vertically, one end face of its long protruding teeth is arranged downward, and the long protruding teeth on the end face are connected to the reinforcement of the L-shaped prefabricated component by sleeve grouting.

[0021] In the assembled rectangular pool disclosed in the present application, the thickness of the flat prefabricated component is not greater than the thickness of the L-shaped prefabricated component.

[0022] In the assembled rectangular pool disclosed in the present application, the end faces of the L-shaped prefabricated components and the flat prefabricated components are set as rough surfaces, and the concave-convex depth of the rough surface is not less than 4 mm.

[0023] In the assembled rectangular water pool disclosed in the present application, the assembled rectangular water pool also has a top cover, which includes a top plate formed by connecting a plurality of one-way multi-rib plates to each other, and a laminated layer formed by post-casting concrete on the upper side of the top plate;

[0024] The rib beams of the one-way dense-rib plate are matched with the grooves of the tooth grooves, and during assembly, the rib beams are placed in the grooves.

[0025] The beneficial effects of the present invention are:

[0026] (1) This application combines different types of prefabricated components into the same form to the greatest extent possible, and adjusts the factors affecting bearing capacity into the same size, thereby reducing the types of prefabricated components and unifying the same specifications and sizes. This application can use fewer specifications and simple forms of prefabricated components to achieve larger scale and more forms of prefabricated pools. Only L-shaped prefabricated components and flat prefabricated components are combined to assemble the main body of the pool. The prefabrication rate is high, and the joints avoid the parts that are unfavorable to the force. It not only conforms to the principles of prefabricated standardization and modularization, but also conforms to the force characteristics of the pool.

[0027] (2) The joints of this application are in the form of tooth grooves with stronger bite and waterproofing effects, which meets the relevant requirements of the pool specification and is adjusted to a staggered assembly method, providing conditions for the staggered splicing of steel bar joints with the smallest joint cavity size, and achieving staggered joints by adjusting the form and position of the components without increasing the specifications of the components. This joint structure can solve the problem that the joint position is a traditional waterproof and force-bearing weak area.

[0028] (3) This application incorporates the pool roof into the pool assembly system. Considering the large span in the width direction of the pool, a prestressed roof in the form of a one-way dense rib plate is selected to form a comprehensive and complete set of pool assembly technology.

[0029] (4) The present application enhances its integrity and ensures its connection performance and waterproof effect by specially designing the joint position and joint structure. In addition, the present application achieves a good combination of the prefabricated base plate and the rigid cushion layer through the post-casting process of the cushion layer.

[0051] See also Figures 1 to 9 As shown, an embodiment of the present application provides a prefabricated rectangular pool, the main purpose of which is to solve the problems of the existing prefabricated components of the pool being of multiple specifications and types and unreasonable joint settings.

[0052] The present application discloses an assembled rectangular pool, comprising:

[0053] L-shaped prefabricated component 3, see Figure 2, 3 As shown, they are connected to each other through joints and enclose the pool wall 1 and part of the pool bottom 2 of the rectangular pool. Among them, the L-shaped prefabricated components 3 at the four corners of the pool wall 1 have two flat plates arranged vertically to form the corners of the pool wall 1, and the remaining L-shaped prefabricated components 3 have one flat plate arranged horizontally to form part of the pool bottom 2, and one flat plate arranged vertically to form part of the pool wall 1. This application takes into account the force principles of various parts of the pool and tries to merge the prefabricated components in different parts. For example, the horizontal corner bending moment at the corner is large, and the vertical bending moment at the bottom of the pool is large. The forces on these two parts are similar and both are unfavorable parts. The components can be merged into an L-shaped prefabricated component 3. By adjusting the spatial arrangement of the L-shaped prefabricated components 3 at different parts, the joints can be avoided in the unfavorable force areas.

[0054] The flat plate prefabricated component 4 is adapted to the filling part of the pool bottom 2 formed by the L-shaped prefabricated component 3, and is connected to the L-shaped prefabricated component 3 through joints to form a complete pool bottom 2. The middle part of the pool bottom 2 can be filled with the flat plate prefabricated component 4 to complete the area outside the partial pool bottom 2 formed by the L-shaped prefabricated component 3.

[0055] The joints of the L-shaped prefabricated components 3 and the flat prefabricated components 4 are integral joints in the form of post-cast strips, and the assembled rectangular pool is formed after the joints are connected. After the prefabricated components are installed, joint cavities are left between adjacent components. The joints of the pool structure are integral joints in the form of post-cast strips, which are wet connections. The size of the cavity at the joint position can meet the requirements of the process to set up components such as cast-in-place diversion pool walls and water weirs. Specifically, the minimum size of the cavity at the joint position meets the requirements of steel bar connection and is not less than 200mm.

[0056] The present application rationally divides the rectangular pool into L-shaped prefabricated components 3 and flat prefabricated components 4. The combination of the two can flexibly realize pool structures of various sizes, reduce the types of prefabricated components, unify the same specifications and sizes, and realize larger-scale and more forms of assembled pools with fewer specifications and simple forms of prefabricated components. Under the premise of meeting the production mold platform and hoisting capabilities, the minimum joints are achieved.

[0057] In order to ensure the modularization of production and standardization of connections for prefabricated water pools, the shape, size and spacing of steel bars of the same type of components remain unchanged, and different bearing capacities can be achieved by adjusting parameters such as concrete grade and steel bar diameter.

[0058] In one embodiment, see Figure 2 , 4 As shown, a plurality of I-beams 21 are arranged below the L-shaped prefabricated components 3 at the four corners of the pool wall 1, and a plurality of cushion blocks 22 are arranged on the lower surface of the pool bottom 2. Figure 4As shown, pads 22 are provided at the four corners of the lower side of the L-shaped prefabricated component 3 and the flat prefabricated component 4 constituting the pool bottom 2. A casting space is formed between the I-beam 21, the pad 22 and the lower bottom surface of the pool bottom 2, and concrete is cast in the casting space to form a cushion layer 23.

[0059] Specifically, the L-shaped prefabricated component 3 is located at the four corners of the pool, and a plurality of I-beams 21 are provided at the lower part of the L-shaped side surface 31 as temporary supports. The distance between the end face of the component and the cushion layer 23 can be changed by changing the web height of the I-beam 21, and the distance can be adjusted within a reasonable range according to assembly needs.

[0060] Specifically, the pool bottom cushion layer 23 is poured after the prefabricated components are installed and positioned at the bottom of the pool. The prefabricated components are supported by cushion blocks 22 to form a cushion layer space. The cushion layer concrete uses self-leveling concrete. Concrete with self-flowing properties such as self-compacting concrete is poured in the pouring space to form a cushion layer. The post-casting cushion layer process ensures the bonding effect between the cushion layer and the bottom plate.

[0061] The assembled water pool of the present application first assembles the pool bottom 2 and the pool wall 1 through L-shaped prefabricated components 3 and flat prefabricated components 4, and then designs the surrounding of the cushion layer 23 to form an enclosure template, and pours cushion layer concrete in the joint cavity. The cushion layer concrete adopts self-leveling concrete, which can achieve the leveling and bonding of the bottom of the pool, and also fix the water pool as a whole to a certain extent.

[0062] The present application adjusts the cushioning process to after the installation of the prefabricated components, selects a suitable type of cushioning concrete, and sets a number of temporary pads 22 under the prefabricated components of the pool bottom 2. The height of the pads 22 is determined by the thickness of the cushioning layer 23. After the prefabricated components are installed and fixed, the four sides of the pool bottom are sealed, and self-leveling concrete is poured at the joints of the pool bottom to level the foundation to form the cushioning layer 23. In this way, a cast-in-place effect is achieved, and the cushioning layer concrete has a certain bonding and fixing ability after solidification, which plays a role in temporarily fixing the prefabricated components.

[0063] Alternatively, to further ensure that the precast components are in a fixed state during pouring, only the concrete joints at the two positions of the pool bottom can be poured first. The concrete for the joints should be micro-expansive concrete, which should be one level higher than the concrete strength of the precast components.

[0064] Alternatively, in order to save steps and construction time, the cushion layer and the pool bottom joints can be cast together.

[0065] In one embodiment, see Figure 1 As shown, when the height of the pool wall 1 of the rectangular pool needs to be increased, an additional pool wall 11 is arranged above the pool wall 1. The additional pool wall 11 is composed of an L-shaped prefabricated component 3 and a flat prefabricated component 4.

[0066] Among them, the two flat plates of the four L-shaped prefabricated components 3 are arranged vertically to form the four corners of the additional pool wall 11, and the flat plate prefabricated components 4 are arranged vertically and connected with the four L-shaped prefabricated components 3 through joints to form the additional pool wall 11.

[0067] This application takes into account the stress principles of various parts of the pool, and tries to merge prefabricated components in different parts. The thickness of the prefabricated components of the pool wall 1 is divided according to the stress analysis. The stress on the upper part of the pool wall 1 is less than that on the lower part of the pool wall 1, and the stress in the middle of the bottom plate is less than that on the bottom plate at the edge of the pool wall 1. These two parts are similar in size and simple in form, and can be merged into a flat prefabricated component 4.

[0068] The above division idea not only takes into account the structural force, but also utilizes the spatial proportional relationship between the height of the pool and the short length of the plane during process design, so that the component division has the same proportional consistency in size. Through reasonable splitting and combination, pool structures of various sizes can be flexibly realized.

[0069] In one embodiment, see Figure 5 As shown, the L-shaped side surfaces 31 on both sides of the L-shaped prefabricated component 3 are provided with teeth grooves 5 along the length direction of the flat plate. Among them, one flat plate is provided with the teeth grooves 5 starting from the convex teeth 51, and the other flat plate is provided with the teeth grooves 5 starting from the grooves 52. When the L-shaped side surfaces 31 of the two L-shaped prefabricated components 3 are connected to each other, the convex teeth 51 correspond to the grooves 52 at the joints. The joints are designed to be in the shape of teeth grooves, and the integrity can be enhanced through bite and other effects. The tooth groove shape is a very reasonable stress form, and the integrity of this area can be enhanced through bite and other effects. In addition, according to relevant specifications, the tooth groove 5 is equivalent to "flat end face + water stop" in terms of joint waterproofing effect. Specifically, the corners of the L-shaped prefabricated component 3 are armpit angle structures, and the L-shaped prefabricated component 3 can be locally thickened according to the stress.

[0070] In order to realize the staggered connection of the steel bar joints at the joint position, the spatial position and the tooth groove arrangement of the L-shaped prefabricated component 3 are adjusted, and the tooth grooves 5 between the adjacent prefabricated components are spliced ​​in a staggered manner, that is, the protruding teeth 51 on one side correspond to the grooves 52 on the other side. The post-cast concrete at the tooth groove 5 is an integral joint in the form of a post-cast belt. The cast-in-place form in this area can better achieve integrity and impermeability.

[0071] In an implementation scenario, in order to simplify the component production process, the straight end face of the L-shaped prefabricated component 3 may not be provided with a tooth groove 5, and only a rough surface may be provided. The length (height) of the L-shaped prefabricated component 3 can be considered as 1 / 3~1 / 2 of the full height of the pool wall 1. The specific value is calculated based on the force analysis and the bending moment as the main factor. The thickness dimension is determined according to the most unfavorable stress position at the end. The board width is limited by the factory mold platform size and hoisting capacity, and can be based on the conventional board module size, such as 1.8m, 2.1m and 2.4m.

[0072] In one embodiment, see Figure 6 As shown, long protruding teeth 41 are provided at both ends of one end face of the flat plate prefabricated component 4, and the conditions for grouting connection of the pre-embedded sleeve in the long protruding teeth 41 are provided, and tooth grooves 5 are provided on the other three end faces. Among them, the tooth grooves 5 on the opposite two end faces of the flat plate prefabricated component 4 are staggered, that is, the protruding teeth 51 on one side correspond to the grooves 52 on the other side. When two flat plate prefabricated components 4 are connected, the protruding teeth 51 correspond to the grooves 52 at the joint. Designing the joint into a tooth groove shape can enhance the integrity through bite and other effects.

[0073] The height of the flat plate prefabricated component 4 is the full height of the pool wall 1 minus the height of the L-shaped prefabricated component 3, and the width is the same as the L-shaped prefabricated component 3. The flat plate prefabricated component 4 has three end faces in the form of tooth grooves, and the other end face only has a long protruding tooth 41 at each end, which is a "three-side tooth groove, single-side support" form. The long protruding tooth 41 is used as a temporary support, and the steel bars at this position can be connected by sleeve grouting. The tooth grooves 5 of the two end faces perpendicular to the end face of the long protruding tooth 41 are staggered to achieve the purpose of staggered assembly of the end face tooth grooves 5 of adjacent components.

[0074] The prefabricated components of the present application are connected by wet method, and post-cast strip joints are used at the pool wall 1 and the pool bottom 2. The joints are designed in the form of tooth grooves, which can enhance the bite effect and overall performance, and the tooth grooves 5 are staggered and assembled, and the protruding teeth 51 correspond to the grooves 52 of the adjacent components, so that the steel bar joints can be arranged at intervals and staggered. The staggered assembly can be achieved by adjusting the form and spatial position of the prefabricated components and the tooth groove arrangement. The size of the cavity at the joint is determined according to the requirements of the steel bar connection and the pouring of cast-in-place concrete, and the width of the narrowest part of the space shall not be less than 200mm. Alternatively, if the size of the cavity of the post-cast strip at the joint is large, the tooth grooves 5 can be assembled in pairs.

[0075] In one embodiment, the L-shaped prefabricated component 3 and the flat prefabricated component 4 are both provided with steel bars, and the four end faces thereof are all provided with steel bars, wherein the place where the steel bars are provided at one end face of the tooth groove 5 is the middle position of the convex tooth 51 and the groove 52. For prefabricated components of the same specification, considering the modularization of the factory formwork production and the standardization of the joint steel bar connection, the concrete strength and the steel bar diameter are adjusted as variable factors to meet the bearing capacity requirements of different parts. The reinforcement ratio of the stressed steel bars is generally 0.3% to 0.8%, which can achieve different bearing capacities in a wide range.

[0076] The L-shaped prefabricated component 3 and the flat prefabricated component 4 are both reinforced at the middle of the convex teeth 51 or the concave grooves 52. The length of the steel bars is determined according to the size of the cavity at the joint and the need for steel bar connection. The joints refer to the specification that "the form of the construction joint of the pool wall 1 should be made into a convex-concave type, a stepped type or an embedded water stop belt", that is, the tooth joints do not need to be provided with an embedded water stop belt (plate).

[0077] In one embodiment, see Figure 1As shown, when the flat prefabricated component 4 constitutes the additional pool wall 11, it is arranged vertically, and one end face of its long protruding teeth 41 is arranged downward, and the long protruding rulers of the end face are connected to the reinforcement of the L-shaped prefabricated component 3 by sleeve grouting. The long protruding teeth 41 serve as temporary supports for the additional pool wall 11 on the lower L-shaped prefabricated component 3. After support, a cavity is formed with the upper end of the lower L-shaped prefabricated component 3, and the vertical reinforcement at the position of the long protruding teeth 41 is connected by sleeve grouting. The long protruding teeth play a role in supporting the formation of the cavity. Since it is impossible to produce reinforcement, the sleeve grouting connection method is adopted. Other reinforcement connection methods can be adopted at the rest of this end face.

[0078] In one embodiment, the thickness of the flat prefabricated component 4 is not greater than the thickness of the L-shaped prefabricated component 3. The corners of the pool bottom 2 and the corners of the pool wall 1 are both parts with greater stress, and the component thickness is larger, while the upper part of the pool wall 1 and the middle part of the pool bottom 2 are parts with less stress, and the component thickness is smaller. Therefore, the thickness of the flat prefabricated component 4 can be less than the thickness of the L-shaped prefabricated component 3. However, when the wall thickness difference is not large or to simplify the production process, it is preferred that the components of the two specifications have the same thickness size. The thickness of the flat prefabricated component 4 is not greater than the thickness of the L-shaped prefabricated component 3, which saves building materials and reduces the hoisting weight according to the force law.

[0079] Specifically, the L-shaped prefabricated component 3 can be made into a partially thickened form, with a thicker thickness at the corner and a thickness change section near the end transitioning to the thickness of a flat prefabricated component, that is, the cross-sectional thickness of the two prefabricated components at the end surface position is consistent.

[0080] In one embodiment, the end faces of the L-shaped prefabricated component 3 and the flat prefabricated component 4 are set to be rough surfaces, and the concave-convex depth of the rough surface is not less than 4 mm. The end face is the bonding surface of the prefabricated component, and the rough surface can increase the bite effect, which is conducive to the joint bearing of the prefabricated part and the cast-in-place part and the coordinated force.

[0081] In one embodiment, see Figure 7 As shown, the assembled rectangular pool also has a top cover 6, which includes a top plate composed of a plurality of one-way dense rib plates 61 connected to each other, and a laminated layer arranged on the upper side of the top plate.

[0082] Specifically, the one-way dense rib plate 61 is a prefabricated component, and the rib beams 62 of the one-way dense rib plate 61 are arranged at intervals along the width direction and are arranged along the length direction. The rib beams 62 of the one-way dense rib plate 61 are matched with the grooves 52 of the tooth grooves 5, and the rib beams 62 fall into the grooves 52 during assembly.

[0083] Specifically, see Figure 8 , 9As shown, the one-way dense rib plate 61 is provided with reserved holes 64 at both ends in its length direction, and a double-layer structural steel bar is arranged inside the flat prefabricated component 4. The steel bars close to the inner side of the water pool extend upward through the reserved holes 64, are bent toward the inner side of the water pool, and are anchored through the overlapping layer. The steel bars close to the outer side of the water pool extend upward, are bent toward the inner side of the water pool, and are connected to the additional steel bars 63 in the overlapping layer.

[0084] This application takes into account the top shape of the prefabricated component of the pool wall 1 and the span of the pool structure exceeding the span of the conventional column grid, and adopts a one-way dense rib plate 61. The rib beam 62 falls in the top joint groove 52 of the prefabricated component of the pool wall 1, and the upper cast-in-place composite layer ensures the integrity of the top cover 6.

[0085] The assembly method of the assembled rectangular pool of the embodiment of the present invention is as follows:

[0086] In the first stage, the prefabricated components at the bottom of the rectangular pool are installed in place. In the second stage, the pool bottom cushion 23 is poured, and the joint cavity at the bottom of the pool is poured. In the third stage, the prefabricated components of the top cover 6 are installed, the steel bars are connected, and the concrete of the superimposed layer on the top of the pool is poured.

[0087] Conventional solutions first cast the lower plain concrete cushion 23 before the pool is constructed. In order to solve the problem of unequal contact between the rigid cushion 23 and the rigid pool bottom 2, the present application places the process of casting the cushion 23 after the prefabricated components of the bottom pool are installed and positioned.

[0088] Based on the above embodiments, the assembled rectangular pool in the embodiment of the present invention has the following advantages:

[0089] (1) This application combines different types of prefabricated components into the same form to the greatest extent possible, and adjusts the factors affecting the bearing capacity into the same size, thereby reducing the types of prefabricated components and unifying the same specifications and sizes. This application can use fewer specifications and simple forms of prefabricated components to achieve larger scales and more forms of prefabricated pools. Only L-shaped prefabricated components 3 and flat prefabricated components 4 are combined to assemble the main body of the pool. The prefabrication rate is high, and the joints avoid the parts that are unfavorable to the force. It not only meets the principles of assembly standardization and modularization, but also meets the force characteristics of the pool.

[0090] (2) The joints of this application are in the form of tooth grooves with stronger bite and waterproofing effects, which meets the relevant requirements of the pool specification and is adjusted to a staggered assembly method, providing conditions for the staggered splicing of steel bar joints with the smallest joint cavity size, and achieving staggered joints by adjusting the form and position of the components without increasing the specifications of the components. This joint structure can solve the problem that the joint position is a traditional waterproof and force-bearing weak area.

[0091] (3) The present application incorporates the pool roof 6 into the pool assembly system. Considering the large span in the width direction of the pool, a prestressed top plate in the form of a one-way dense rib plate 61 is selected to form a comprehensive and complete set of pool assembly technology.

[0092] (4) The present application enhances its integrity and ensures its connection performance and waterproof effect by specially designing the joint position and joint structure. In addition, the present application achieves a good combination of the prefabricated base plate and the rigid cushion layer through the post-casting process of the cushion layer.

[0093] 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.
