[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] The prefabricated bathroom structure with adjacent walls provided in the embodiments of this application will now be described. Please refer to... Figure 1 The prefabricated toilet structure with adjacent walls includes at least two prefabricated toilets 1. Each prefabricated toilet 1 includes a base plate 102 and a side plate 101. The side plate 101 is arranged around the base plate 102 to enclose the internal space of the toilet. A casting space 20 is formed at the common wall of two adjacent prefabricated toilets 1. A casting component 2 is provided in the casting space 20 so that the casting component 2 connects the two adjacent prefabricated toilets 1.

[0024] In this prefabricated bathroom structure with adjacent walls, the arrangement of at least two prefabricated bathrooms 1, along with their respective base slabs 102 and side panels 101, forms a more integrated layout. The side panels 101 of each prefabricated bathroom 1 are arranged around the base slab 102 to enclose the internal space, which not only ensures the independent functional area of ​​each bathroom but also provides a basic structure for connecting adjacent bathrooms.

[0025] The casting space 20 formed between two adjacent prefabricated toilets 1 is located on the side of the side panel 101 away from the interior space. The side panel 101, as the side boundary of the casting space 20, can provide a stable molding environment for the casting component 2, ensuring that the casting component 2 maintains the preset shape during the solidification process, thereby accurately realizing the connection between adjacent prefabricated toilets 1.

[0026] Once the casting material within the casting space 20 forms the casting component 2, the casting component 2 will tightly connect with the side panels 101 of the prefabricated toilets 1 on both sides, forming a robust connection structure. This connection method not only transfers the force between the two toilets and enhances the stability of the overall structure, but more importantly, the interconnection of two adjacent prefabricated toilets 1 through the casting component 2 allows for the completion of on-site work on at least two toilets at once during construction. This greatly simplifies the construction process, reduces repetitive operations when constructing each toilet individually, and significantly improves construction efficiency. Simultaneously, the adjacent placement of toilets facilitates the centralized layout and construction of pipes. Various water supply, drainage, and ventilation pipes can be centrally planned and laid in adjacent areas, reducing the complexity of pipe installation and minimizing interference from cross-operations, thereby further improving the overall construction efficiency of the toilets.

[0027] Please see Figure 2In some embodiments of this application, the side panel 101 is provided with an exposed first reserved part 11 on the side away from the internal space, and the first reserved parts 11 of two adjacent prefabricated toilets 1 extend into the pouring space 20 so that the pouring part 2 covers the first reserved parts 11 of the two adjacent prefabricated toilets 1.

[0028] An exposed first reserved component 11 is provided on the side of the side panel 101 facing away from the internal space, and the first reserved component 11 of the adjacent prefabricated toilet 1 extends into the casting space 20. This design has a significant strengthening effect on the connection structure. The first reserved component 11 is exposed and extends into the casting space 20, so that the casting component 2 can fully wrap the reserved component, forming a mechanical interlocking structure. This interlocking is different from simple surface bonding. The embedded relationship improves the pull-out resistance and shear resistance between the two. When the adjacent prefabricated toilet 1 is subjected to lateral thrust or tension, the first reserved component 11 can transfer the force to the casting component 2. The integrity of the casting component 2 is used to distribute the load, avoiding the loosening of the connection caused by the force relying solely on the contact surface between the side panel 101 and the casting component 2. At the same time, the casting component 2 wrapping the first reserved component 11 can reduce the contact between the reserved component and the outside, reduce the risk of corrosion, and extend the service life of the connection structure. Furthermore, the first reserved part 11 fills part of the gap in the pouring space 20, making the pouring part 2 and the side plate 101 more tightly connected, further improving the sealing of the bathroom and reducing water leakage and seepage problems.

[0029] Please see Figure 2 In some embodiments of this application, the first reserved component 11 includes an annular sleeve, and the annular sleeves of two adjacent prefabricated toilets 1 partially overlap.

[0030] When the first reserved component 11 is an annular sleeve, and the annular sleeves of two adjacent precast toilets 1 partially overlap, the connection strength and cooperative stress-bearing capacity between the cast-in-place component 2 and the two precast toilets 1 on both sides can be further improved. The annular sleeve itself has a closed ring structure, and its contact area with the cast-in-place component 2 is larger, which can form a multi-directional mechanical engagement with the cast-in-place component 2 through the annular contour. The partial overlap of adjacent annular sleeves makes the first reserved components 11 of the two precast toilets 1 form a cross-connected stress node in the casting space 20. This overlapping design allows the cast-in-place component 2 to firmly lock the overlapping annular sleeves on both sides when wrapping the annular sleeve, so that the force borne by a single annular sleeve can be transferred to the annular sleeve on the other side through the overlapping area, avoiding stress concentration, improving the shear and tensile resistance of the connection structure, and enabling a stable connection between the precast toilets 1.

[0031] Please see Figure 2 In some embodiments of this application, the prefabricated bathroom structure with adjacent walls includes a pin 13, which is disposed within the cast-in-place component 2. Overlapping annular hoops form an overlapping space, and the pin 13 is disposed within the overlapping space.

[0032] The overlapping annular sleeves are connected by the cast-in-place component 2, and their stress mainly depends on the bond strength between the cast-in-place component 2 and the annular sleeves. Under the action of large external forces, such as strong winds or seismic loads, the annular sleeves are prone to relative displacement, which will reduce the integrity of the connection node and even affect the structural stability.

[0033] After the pin 13 is set in the overlapping space, it can restrict the relative displacement of the ring sleeve in multiple directions such as horizontal and vertical, so that the originally independent overlapping ring sleeves can form a whole that works together to bear force, thus enhancing the integrity between the ring sleeves.

[0034] This improvement in integration directly enhances the connection strength. When the adjacent precast toilet 1 is subjected to tension, the pin 13 can transfer part of the tension through its own stiffness, reducing the bearing pressure of the interface bonding force between the annular sleeve and the cast part 2, and reducing the risk of interface separation; when subjected to shear force, the pin 13 is in close contact with the inner wall of the annular sleeve, and directly resists the shear force with its own shear resistance, sharing the load on the annular sleeve and preventing the annular sleeve from deforming due to excessive shear force.

[0035] Please see Figure 3 In some embodiments of this application, the side plate 101 includes a steel reinforcement skeleton, which includes transverse steel bars 12, and the first reserved part 11 is connected to the transverse steel bars 12.

[0036] The transverse reinforcing bar 12, as an important component of the reinforcing steel cage, connects with other reinforcing bars in the cage to form an integrated load-bearing frame. When the first pre-installed part 11 is connected to the transverse reinforcing bar 12, it establishes a direct connection with this integrated frame. Compared to simply embedding the first pre-installed part 11 in the surface of the prefabricated bathroom 1, this connection method allows the first pre-installed part 11 to be more firmly fixed to the prefabricated bathroom 1. Under stress, the force borne by the first pre-installed part 11 can be directly transferred to the transverse reinforcing bar 12, and then to the entire reinforcing steel cage through the transverse reinforcing bar 12. This avoids loosening or detachment of the first pre-installed part 11 and the prefabricated bathroom 1 due to weak connection, significantly improving the connection strength between the first pre-installed part 11 and the prefabricated bathroom 1.

[0037] If the first reserved part 11 is a ring sleeve, it is connected to the transverse steel bar 12. Therefore, the ring sleeve is usually arranged vertically. Of course, in special cases, the ring sleeve can also be arranged at a certain angle.

[0038] The prefabricated bathroom 1 includes multiple horizontal steel bars 12 and multiple annular hoops. For this situation, such as... Figure 2 and Figure 3 As shown, a ring-shaped sleeve can be fitted onto a transverse reinforcing bar 12, or it can be as follows: Figure 4 As shown, a ring-shaped sleeve is fitted onto multiple transverse reinforcing bars 12, for example... Figure 4 In the illustrated embodiment, one annular sleeve is fitted onto two transverse reinforcing bars 12. In addition, one annular sleeve can be fitted onto more transverse reinforcing bars 12. Generally, the annular sleeve fitted onto one transverse reinforcing bar 12 is smaller in size and can be called a small sleeve, while the annular sleeve fitted onto multiple transverse reinforcing bars 12 is larger in size and can be called a large sleeve.

[0039] Please see Figure 2 For the former, each annular sleeve corresponds to a transverse reinforcing bar 12, allowing for more precise positioning of the annular sleeve on the transverse reinforcing bar 12 during the fabrication of the precast toilet 1. During the assembly of the precast toilet 1 on the construction site, the clear positioning of the annular sleeves and transverse reinforcing bars 12 makes it easier for the annular sleeves of adjacent precast toilet 1 to achieve precise overlap, ensuring that the size and shape of the pouring space 20 meet design requirements. This facilitates the subsequent pouring of the casting component 2 and further improves construction quality. When the connecting structure is subjected to external forces, each annular sleeve is fitted onto a transverse reinforcing bar 12, resulting in a relatively clear force transmission path. The external force is directly transmitted through the annular sleeve to the connected transverse reinforcing bar 12, which then distributes the force to other parts of the precast toilet 1. When subjected to shear or tensile forces, each combination of annular sleeve and transverse reinforcing bar 12 can function independently with minimal interference between them. However, when using a ring sleeve to enclose a transverse steel bar 12, the number of ring sleeves needs to be increased, especially when the transverse steel bars 12 are relatively dense. The number of steel bars will increase dramatically, which will not only lead to an increase in material consumption and thus increase project costs, but also increase the difficulty of construction.

[0040] Please see Figure 4 For the latter, a single annular sleeve accommodates multiple transverse reinforcing bars 12, connecting them together to form a single unit. When subjected to external forces, the multiple transverse reinforcing bars 12 can share the load, distributing the force more evenly throughout the prefabricated bathroom 1, significantly enhancing the load-bearing capacity and deformation resistance of the connection points. Compared to using a single annular sleeve for each transverse reinforcing bar 12, using a single annular sleeve for multiple transverse reinforcing bars 12 reduces the number of annular sleeves required. This reduces material costs while still meeting connection strength requirements. Furthermore, reducing the number of annular sleeves simplifies the construction process and improves efficiency. Construction workers no longer need to install an annular sleeve for each transverse reinforcing bar 12, reducing installation time and labor intensity.

[0041] Small and large hoops can be used in different application scenarios. For example, in some embodiments, the prefabricated bathroom 1 includes a wall section, on which multiple annular reinforcing bars and multiple annular hoops are provided; in the wall section, one annular hoop is fitted onto one transverse reinforcing bar 12. Typically, the wall can be divided into a wall section and an edge component section. The transverse reinforcing bars 12 in the wall section are usually sparser, while the transverse reinforcing bars 12 in the edge component section are usually denser. If one annular hoop is fitted onto multiple transverse reinforcing bars 12 in the wall section, it is easy to cause the size of the annular hoop to be too large, reducing the stability of the structure. However, if one annular hoop is fitted onto one transverse reinforcing bar 12, the problem of excessively dense reinforcing bars will not occur because the transverse reinforcing bars 12 are relatively sparse.

[0042] For example, in other embodiments, the prefabricated toilet 1 includes an edge component portion, on which a plurality of annular steel bars and a plurality of annular hoops are provided; in the edge component portion, an annular hoop is fitted onto a plurality of transverse steel bars 12.

[0043] The transverse reinforcing bars 12 in the edge component section are often more densely packed. If a ring-shaped sleeve is used to enclose each transverse reinforcing bar 12 in the edge component section, the number of ring-shaped sleeves will increase significantly due to the dense distribution of transverse reinforcing bars 12 in the edge component section itself. Too many ring-shaped sleeves concentrated in the limited space of the edge component section can easily lead to a crowded layout and mutual interference. This will not only hinder the filling of the cast-in-place component 2, resulting in insufficient pouring and voids, but may also cause the ring-shaped sleeves to be too close together, resulting in mutual restraint under stress and inability to evenly transfer the load, thus affecting the stability of the entire edge component section connection structure.

[0044] In the edge component section, a single annular sleeve is fitted onto multiple transverse reinforcing bars 12, which effectively accommodates the dense arrangement of these bars. This prevents the annular sleeve from becoming cluttered and disorganized due to the large number of reinforcing bars; instead, it consolidates the force distribution across multiple transverse reinforcing bars 12 through a single annular sleeve, making force transmission more concentrated and efficient, and enhancing the overall integrity of the connection points in the edge component section. Simultaneously, it avoids construction inconveniences caused by an excessive number of annular sleeves.

[0045] In some embodiments, an annular sleeve (first reserved part 11) can be fitted onto two adjacent transverse reinforcing bars 12. However, the number of transverse reinforcing bars 12 may be even or odd. For an even number of transverse reinforcing bars 12, an annular sleeve can be fitted onto every two adjacent transverse reinforcing bars 12, and they will be perfectly matched. However, for an odd number of transverse reinforcing bars 12, if an annular sleeve is fitted onto every two adjacent transverse reinforcing bars 12, one transverse reinforcing bar 12 will be left unfit. In this case, as follows... Figure 11 As shown, a ring sleeve can be separately fitted on one of the transverse steel bars 12, that is, the method of using a large sleeve and a small sleeve is adopted.

[0046] Please see Figure 3 In some embodiments of this application, the pin 13 is located on the first side 111 of the annular sleeve, which is the side of the annular sleeve away from the prefabricated toilet 1 where it is located.

[0047] When the two prefabricated toilets 1 tend to separate, the annular clamp will tend to move away from the other prefabricated toilet 1. Since the pin 13 is located on the first side 111 of the annular clamp, it is exactly on the path of possible movement of the annular clamp and can directly block the annular clamp. This blocking does not rely solely on the friction between the pin 13 and the annular clamp, but rather on the structural strength of the pin 13 itself, which directly bears the thrust generated by the annular clamp due to the separation tendency.

[0048] Specifically, when the precast toilet 1 is subjected to a tensile force that causes separation, the annular sleeve makes close contact with the surface of the pin 13 on its first side 111, transmitting the force through the pin 13 to the cast-in-place 2 and the annular sleeve on the other side, thus directly counteracting the separation tendency. This direct resistance method, compared to relying solely on the adhesive force between the annular sleeve and the cast-in-place 2 to resist separation, can more efficiently disperse and transmit the tensile force, reducing the risk of the annular sleeve separating from the cast-in-place 2 due to excessive tensile force, significantly enhancing the connection reliability in the separation direction, and further improving the overall anti-separation capability of the connection structure.

[0049] Please see Figure 4 and Figure 5 In some embodiments of this application, the pin 13 is located on the second side 112 of the annular sleeve, which is the overlapping side of the overlapping annular sleeves. In the height direction, if the two prefabricated toilets 1 tend to misalign, the overlapping annular sleeves will slide relative to each other in the height direction. Since the pin 13 is located on the overlapping side of the annular sleeves and is disposed within the overlapping space, it will simultaneously contact both overlapping annular sleeves. When the annular sleeves slide relative to each other due to misalignment, the pin 13 will exert a reverse restraining force on the annular sleeves on both sides, hindering this sliding and thus reducing the amount of misalignment of the prefabricated toilet 1 in the height direction.

[0050] When the two prefabricated toilets 1 tend to separate in the height direction, the overlapping annular sleeves will tend to move away from each other. The pin 13, located on the overlapping side, can transmit the force generated by the separation tendency between the two annular sleeves through close contact, keeping them overlapping. This directly enhances the tightness of the connection of the annular sleeves in the height direction, thereby reducing the risk of separation of the prefabricated toilets 1 in this direction and improving the stability of the connection structure in the height direction.

[0051] In summary, the two arrangements of the above-mentioned pins 13 are more effective in resisting separation forces in the horizontal direction perpendicular to the prefabricated bathroom 1, while the latter is more effective in resisting separation forces in the vertical direction. The specific use of these two methods can be determined according to the stress conditions of the prefabricated bathroom 1. One arrangement of pins 13 can be used alone, or both arrangements of pins 13 can be used simultaneously.

[0052] Please see Figure 2 In some embodiments of this application, the adjacent shared wall prefabricated bathroom structure further includes a first component located above the side plate 101 of the prefabricated bathroom 1 and a second component located below the side plate 101 of the prefabricated bathroom 1; the steel reinforcement frame further includes a first vertical steel bar 14, the first component includes a second vertical steel bar 31, the second component includes a third vertical steel bar 41, the upper end of the first vertical steel bar 14 is connected to the second vertical steel bar 31, and the lower end of the first vertical steel bar 14 is connected to the third vertical steel bar 41.

[0053] The first and second structural members are typically wall structures located above and below the prefabricated bathroom. The upper end of the first vertical reinforcing bar 14 on the prefabricated bathroom 1 is connected to the second vertical reinforcing bar 31 of the first structural member, and the lower end is connected to the third vertical reinforcing bar 41 of the second structural member. This connection method tightly connects the prefabricated bathroom 1 with the upper and lower structural members. When the structure is subjected to vertical loads, such as its own weight or pressure transmitted from above, the load can be transferred through the second vertical reinforcing bar 31 to the first vertical reinforcing bar 14, and then from the first vertical reinforcing bar 14 to the third vertical reinforcing bar 41, ultimately distributing it to the lower structure. This avoids load concentration at the connection point between the prefabricated bathroom 1 and the upper and lower structural members, reducing deformation or damage caused by excessive local pressure. Simultaneously, this vertical reinforcing bar connection design effectively resists relative displacement in the vertical direction. For example, when subjected to horizontal forces such as earthquakes that induce vertical vibrations, the connection between the first vertical steel bar 14 and the second and third vertical steel bars 41 can limit the vertical displacement between the prefabricated bathroom 1 and the first and second components, ensuring the coordinated deformation of the three components in the vertical direction and improving the stability of the entire bathroom structure under dynamic loads.

[0054] Furthermore, this connection method complements the lateral connection of the ring sleeve. The horizontal connection strength is ensured by the overlap of the ring sleeve and the wrapping of the cast-in-place component 2, while the vertical connection is strengthened by the connection of the steel bars. This allows the prefabricated toilet 1 to form a stable whole with the surrounding structure in three-dimensional space, further improving the reliability and durability of the toilet structure.

[0055] like Figure 2 and Figure 6 As shown, the side panel 101 is usually divided according to the wall structure, and can be divided into the wall body part and the edge component part, among which... Figure 2 This is a schematic diagram of the edge component section. Figure 6 This is a schematic diagram of the wall body. The horizontal reinforcing bars 12 in the wall body are usually sparser, while the horizontal reinforcing bars 12 in the edge members are usually denser. The first vertical reinforcing bar 14 in the edge members is also relatively thicker, and it can be connected using the sleeve 51, the second vertical reinforcing bar 31, and the third vertical reinforcing bar 41, while the first vertical reinforcing bar 14 in the wall body is relatively thinner and is not suitable for connection using the sleeve 51.

[0056] like Figure 7 and Figure 8 As shown, in some embodiments of this application, the prefabricated bathroom structure with adjacent walls includes lapped steel bars 5, which extend from the first component through the prefabricated bathroom 1 to the second component, and the lapped steel bars 5 are sequentially lapped with the second vertical steel bar 31, the first vertical steel bar and the third vertical steel bar 41.

[0057] The lapped reinforcement 5, sequentially lapped with each vertical reinforcement, constructs an interwoven reinforcement network. This network structure does not allow each reinforcement to bear the load independently; instead, the force is transferred through the lap joints, enabling all related reinforcements to share the load. When a vertical force is applied, the force can be quickly distributed to multiple reinforcements through the lap joints, preventing damage to individual reinforcements due to concentrated stress and significantly increasing the structure's load-bearing capacity. Because the lapped reinforcement 5 penetrates multiple sections and laps with different vertical reinforcements, the force transfer is smoother. For example, when the first component is subjected to downward pressure, the pressure can be transferred to the lapped reinforcement 5 via the second vertical reinforcement 31, and then from the lapped reinforcement 5 to the first vertical reinforcement 14 and the third vertical reinforcement 41, ultimately reaching the second component. The entire process involves no significant interruption or abrupt change in force, reducing local structural damage caused by poor force transfer. This lapping method is relatively flexible in operation. When the prefabricated bathroom 1 is installed with the first and second components, the lapped steel bars 5 and the lapped vertical steel bars can compensate for the positioning deviation during the installation process to a certain extent, ensure the reliability of the steel bar connection, and provide a stable steel bar skeleton for the subsequent pouring operation. This is conducive to the formation of the cast component 2 and the steel bars into a whole, further enhancing the stability of the structure.

[0058] Please see Figure 9 and Figure 10 In some embodiments of this application, the second vertical steel bar 31 is lapped with the first vertical steel bar 14, and the third vertical steel bar 41 is welded to the first vertical steel bar 14.

[0059] The second vertical reinforcing bar 31 is welded to the first vertical reinforcing bar 14, and the third vertical reinforcing bar 41 is lapped to the first vertical reinforcing bar 14. The upper welded connection provides strong rigidity for the connection between the first component and the prefabricated toilet 1, which is suitable for scenarios where the first component needs to withstand large lateral forces, resulting in complex vertical stress, and ensures stable force transmission. The lower lapped connection can accommodate possible installation errors in the second component, and at the same time plays an auxiliary role in dispersing vertical loads, making the overall stress more balanced.

[0060] Combining the two connection methods utilizes the flexibility of lap joints to accommodate construction errors, while leveraging the rigidity of welding to enhance the connection strength of critical components. Under vertical loads, the welded joints can bear the main load transfer task, while the lap joints assist in distributing the load, avoiding the limitations that may exist with a single connection method. This combination makes the vertical connection between the first component, prefabricated toilet 1, and the second component more adaptable. Whether under static or dynamic loads, it ensures the coordinated stress distribution of the overall structure, improving the safety and durability of the toilet structure.

[0061] Because the first vertical steel bar 14 in the wall body is relatively thin, the connection method of the first vertical steel bar 14 in the above two embodiments is more suitable for the wall body.

[0062] Please see Figure 2 In some embodiments of this application, the bottom plate 102 is provided with an exposed second reserved part 15 on the side away from the internal space. The second reserved part 15 extends into the casting space 20 so that the casting part 2 covers the second reserved parts 15 of two adjacent prefabricated toilets 1.

[0063] The base slab 102 serves as the foundation load-bearing structure of the precast toilet 1, and its connection stability with adjacent precast toilets 1 directly affects the stress balance of the overall structure. The second reserved component 15 protrudes from the outside of the base slab 102 and extends into the pouring space 20, allowing the poured component 2 to fully integrate with the second reserved components 15 of the base slabs 102 on both sides during the filling process. The second reserved component 15 can adopt various structures, such as frame-shaped, ring-shaped, L-shaped, etc. Figure 2 In the illustrated embodiment, the second reserved component 15 is a bent L-shaped structure. After the cast-in-place component 2 solidifies, it firmly wraps around the second reserved components 15 on both sides, forming a mechanical interlocking node at the bottom. This allows the base plates 102 of adjacent prefabricated toilets 1 to form a cooperative load-bearing structure through the cast-in-place component 2 and the second reserved component 15. This connection method effectively resists the relative horizontal displacement of adjacent prefabricated toilets 1. For example, when a prefabricated toilet 1 is subjected to lateral thrust, the second reserved component 15 of the base plate 102 transmits the force through the cast-in-place component 2, causing the base plates 102 on both sides to restrain each other, preventing the overall structure from tilting due to loose bottom connections.

[0064] Furthermore, the second reserved component 15 and the first reserved component 11 on the previously mentioned side plate 101 form a vertically corresponding connection system. The first reserved component 11 on the side plate 101 mainly bears the lateral force transmission, while the second reserved component 15 on the bottom plate 102 focuses on the stable connection at the bottom. The combination of the two makes the connection between adjacent prefabricated toilets 1 more reliable in both vertical and horizontal directions, providing double protection for the stability of the overall structure.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
