Description

Technical Field

[0001] This invention relates to the field of prefabricated buildings, and in particular to a bathroom mold, module, and its construction method. Background Technology

[0002] Prefabricated modular bathrooms, due to their significant advantages in construction speed, energy conservation and environmental protection, cost-effectiveness, functional integration, space utilization, and health and safety, have become one of the components that best exemplify the advantages of prefabricated construction. A prefabricated modular bathroom consists of a waterproof tray, wall panels, ceiling panels, and supporting joists as the main frame, combined with various sanitary ware and functional accessories, and is assembled as a single, independent bathroom module on-site through hoisting.

[0003] However, existing modular bathrooms are mainly designed for prefabricated concrete structures. When designed for prefabricated steel structures, they still suffer from defects such as unreasonable connection structures, low stability, low space utilization, and poor comfort.

[0004] like Figure 1 As shown, this is a prefabricated bathroom module widely used in current prefabricated buildings. This module employs a non-load-bearing design concept, meaning its structural system is independent of the main building and does not participate in the overall structural load transfer. During construction, it can be installed using either on-site assembly or overall hoisting. The module uses lightweight composite materials, significantly reducing its weight compared to traditional cast-in-place bathrooms. However, its bottom support system exhibits a "structure-surface decoupling" phenomenon. When the vertical load is large, the bathroom floor deflection is significant, exceeding the human comfort threshold. Specific problems with this prefabricated bathroom module are as follows: Weak interface connection: The bottom support system adopts a point support design, which results in discontinuous force transmission path and obvious local stress concentration; in addition, there is a gap between the bathroom chassis and the building structure's base plate, resulting in a poor user experience when walking in the bathroom; Low space utilization: There are non-standard gaps between the side panels of the module and the wall panels of the main structure, which reduces the space utilization of the bathroom itself. Summary of the Invention

[0005] The problem solved by this invention is to provide a bathroom mold shell, module, and construction method thereof.

[0006] In a first aspect, the present invention discloses a bathroom formwork, comprising an integrally formed base plate, a top plate, and several side wall panels. The top plate is disposed opposite to the base plate, the bottom ends of the several side wall panels are connected to the base plate, and the top ends of the several side wall panels are connected to the top plate. Several crisscrossing ribs are fixed to the bottom end of the base plate, and the ribs are used to support the steel beams of the building structure. Embedded angle steel protruding from the outer wall surface of the side wall panels is fixed to the side wall panels, and the embedded angle steel is used to fix and connect to the steel beams of the building structure. The base plate serves as the structural plate of the building structure, and the side wall panels serve as the wall panels of the building structure.

[0007] In some embodiments, a plurality of vertically arranged stiffening plates are fixed on the outer wall surface of the side wall panel, and the stiffening plates protrude outward from the outer wall surface of the side wall panel. The stiffening plates are used to support the upper flange of the steel beam, and the bottom end of the stiffening plate is spaced from the bottom end of the side wall panel, so that when the stiffening plate is supported on the upper flange of the steel beam, the rib beam at the bottom end of the side wall panel is located below the upper flange.

[0008] In some embodiments, the embedded angle steel is fixedly connected to the side wall plate and also fixedly connected to the bottom end of the stiffening plate. When the bottom end of the stiffening plate rests on the upper flange of the steel beam, the embedded angle steel is welded to the upper flange of the steel beam.

[0009] In some embodiments, the lower flange of the steel beam is longer than the upper flange, and the rib beam is mounted on the lower flange.

[0010] In some embodiments, a rib beam support plate is fixedly connected to the web of the steel beam. The rib beam support plate is located below the upper flange, and the length of the rib beam support plate is greater than the length of the upper flange. The rib beam rests on the rib beam support plate.

[0011] In some embodiments, a first electromechanical conduit is laid in the space between adjacent stiffeners.

[0012] In some embodiments, the base plate, the top plate, the side wall plate, the rib beam, and the stiffening plate are made of ultra-high performance concrete.

[0013] In some embodiments, the top plate is provided with a second electromechanical pipeline.

[0014] In a second aspect, the present invention discloses a toilet module, including an interior system and the toilet mold shell described in the first aspect; the interior system is fixed in the space inside the toilet mold shell.

[0015] Thirdly, the present invention discloses a construction method for a bathroom module, used for constructing the bathroom module as described in the second aspect, the construction method comprising: After the steel beams of this floor are installed in the main building structure, the bathroom module of this floor is hoisted onto the steel beams of this floor; wherein, the rib beam overlaps the steel beams of this floor; Weld the embedded angle steel to the steel beam of this layer; Install the steel beams for the next floor.

[0016] Beneficial Effects: This invention provides a bathroom formwork, module, and construction method thereof. The bathroom formwork includes an integrally formed base plate, top plate, and several side wall panels. The top plate is positioned opposite to the base plate. The bottom ends of the side wall panels are connected to the base plate, and the top ends of the side wall panels are connected to the top plate. Several crisscrossing ribs are fixed to the bottom end of the base plate, and these ribs are used to support the steel beams of the building structure. Embedded angle steel protruding from the outer surface of the side wall panels is fixed to the side wall panels, and these embedded angle steels are used to fix and connect to the steel beams of the building structure. The base plate serves as the structural plate of the building structure, and the side wall panels serve as the wall panels of the building structure. By setting ribs and embedded angle steels, the structural strength of the bathroom formwork is improved, while a stable connection method for the prefabricated steel structure building structure is provided. This solves the problem that existing bathroom modules are mainly adapted to prefabricated concrete structures, and when adapted to prefabricated steel structures, they suffer from unreasonable connection structures and low stability. Furthermore, the bottom plate and side wall panels of the bathroom module can serve as structural slabs and wall panels of the main building in the bathroom area, reducing the weight of the main building and eliminating the gap between the bathroom module and the main building structure in the prior art, thereby improving space utilization and enhancing user experience.

[0025] like Figures 2 to 6 As shown, Figure 2 This is a horizontal cross-sectional view of the bathroom mold shell provided in an embodiment of the present invention; Figure 3 for Figure 2 The diagram shows a cross-sectional view of the modular bathroom casing along the aa direction. Figure 4 for Figure 2 The diagram shows a cross-sectional view of the modular bathroom casing along the bb direction. Figure 5 for Figure 4 A magnified view of part A of the modular bathroom casing shown; Figure 6 for Figure 4 The enlarged view of part B of the modular bathroom shell shown; see also Figures 2 to 3. Figure 6 This invention discloses a bathroom formwork, applicable to prefabricated steel structure buildings, enabling high integration of functional units and the main building structure. The bathroom formwork includes an integrally formed base plate 1, a top plate 2, and several side wall panels 3. The top plate 2 is positioned opposite to the base plate 1. The bottom ends of the side wall panels 3 are connected to the base plate 1, and the top ends of the side wall panels 3 are connected to the top plate 2. Several intersecting ribs 4 are fixed to the bottom end of the base plate 1, and these ribs 4 are used to support the steel beams 8 of the main building structure. Embedded angle steels 5 protruding from the outer surface of the side wall panels 3 are fixedly attached to the side wall panels 3, and these embedded angle steels 5 are used for fixed connection to the steel beams 8 of the main building structure. The base plate 1 serves as the structural plate of the main building structure, and the side wall panels 3 serve as the wall panels of the main building structure.

[0026] In this embodiment, the bathroom formwork is a hollow, modular structure. This formwork is cast in a factory using ultra-high performance concrete (UHPC) in a single pour, meaning the base plate 1, top plate 2, side wall panels 3, and ribs 4 are integrally formed. The side wall panels 3 can consist of four pieces, which, together with one top plate 2 and one base plate 1, form a rectangular shell. Due to the extremely high strength, excellent durability, and good toughness of ultra-high performance concrete, the weight of the bathroom formwork can be reduced while maintaining the same structural strength requirements. Furthermore, since the base plate 1, top plate 2, and side wall panels 3 are integrally formed, leakage problems in the bathroom can be reduced, and its fire resistance can be improved.

[0027] Rib beams 4 are cast in one piece with the base plate 1 during pouring. They serve two purposes: firstly, to strengthen the structural strength of the base plate 1 and maintain the overall structural strength of the bathroom formwork; secondly, they act as connectors to the main body of the prefabricated steel structure building. Several intersecting rib beams 4 are fixed to the bottom of the base plate 1. Taking a rectangular base plate 1 as an example, the transverse rib beams 4 are parallel to the short side of the base plate 1, and the longitudinal rib beams 4 are parallel to the long side of the base plate 1. In this embodiment, there can be three transverse rib beams 4 and two longitudinal rib beams 4. When connecting to the steel beams 8 of the main building structure, the rib beams 4 are erected on the steel beams 8 of the main building structure, which also include longitudinal and transverse steel beams 8. During erection, the transverse rib beams 4 are parallel to the transverse steel beams 8, and their ends are respectively erected on two longitudinal steel beams 8; similarly, the longitudinal rib beams 4 are parallel to the longitudinal steel beams 8, and their ends are respectively erected on two transverse steel beams 8. This method, which combines longitudinal and lateral support and is supported at both ends, solves the problem of discontinuous force transmission path and significant local stress concentration caused by point supports in existing technologies.

[0028] Pre-embedded angle steel 5 is embedded in the formwork of the side wall panel 3 before it is cast. Multiple pre-embedded angle steel 5s are spaced apart along the circumference of the side wall panel 3. Each pre-embedded angle steel 5 includes a first steel plate and a second steel plate that are perpendicular to each other. The vertical first steel plate is embedded in the side wall panel 3, while the horizontal second steel plate protrudes from the outer wall surface of the side wall panel 3 to facilitate welding of the second steel plate to the steel beams 8 of the main building structure. Because the pre-embedded angle steel 5 is arranged along the circumference of the side wall panel 3, it can be welded to both the longitudinally and transversely arranged steel beams 8, thereby strengthening the connection stability of the bathroom formwork and further solving the problem of weak interface connections in the prior art.

[0029] In this embodiment, the base plate 1 of the bathroom formwork directly serves as the structural slab of the main building in the bathroom area, and the side wall panels 3 directly serve as the wall panels of the main building in the bathroom area. Therefore, in this bathroom area, The main building structure does not require additional structural slabs and wall panels, which reduces the overall weight of the building. Furthermore, unlike the prior art solutions, there is no gap between the bathroom base and the building structure's base slab 1, thus avoiding the discomfort of a hollow base slab when users step on it. Also, unlike the prior art solutions, there are no non-standard gaps between the module's side panels and the main structure's wall panels, thereby improving the bathroom's space utilization.

[0030] In summary, the embodiments of the present invention utilize ultra-high performance concrete to integrally mold the bathroom formwork in a factory. Compared to traditional cast-in-place concrete, this approach saves on-site wet work and improves construction efficiency. Furthermore, it enhances the structural strength of the bathroom formwork, addressing the problem in existing technologies where lightweight design leads to low overall bending stiffness, resulting in significant vibration under dynamic loads and impacting user comfort. This reduces concrete usage, thus decreasing the weight of the bathroom formwork. Additionally, the high strength of ultra-high performance concrete and the integral molding method minimize seams in the formwork, improving its waterproof, thermal insulation, and fireproofing properties.

[0031] Furthermore, by setting rib beams 4 and embedded angle steel 5, this embodiment of the invention not only improves the structural strength of the bathroom module itself, but also provides a stable connection method for the main body of the prefabricated steel structure building, achieving a high degree of integration between functional units and the main structure of the building. This solves the problem that in the prior art, bathroom modules are mainly adapted to prefabricated concrete structures, but when adapted to prefabricated steel structures, there are still problems such as unreasonable connection structures and low stability.

[0032] Furthermore, the bathroom formwork using ultra-high performance concrete has a base plate 1 and side wall plates 3 that can serve as structural plates and wall panels for the main building in the bathroom area, reducing the weight of the main building and eliminating the gap between the bathroom module and the main building structure in the prior art, thereby improving space utilization and enhancing the user experience.

[0033] In one embodiment, a plurality of vertically arranged stiffening plates 6 are fixed on the outer wall surface of the side wall panel 3, and the stiffening plates 6 protrude outward from the outer wall surface of the side wall panel 3. The stiffening plates 6 are used to support the upper flange 81 of the steel beam 8. The bottom end of the stiffening plate 6 is spaced from the bottom end of the side wall panel 3, so that when the stiffening plate 6 is supported on the upper flange 81 of the steel beam 8, the rib beam 4 on the bottom end of the side wall panel 3 is located below the upper flange 81.

[0034] In this embodiment, the stiffening plate 6 can improve the structural strength of the side wall panel 3 without increasing its thickness, thereby reducing the amount of concrete used and the weight of the bathroom module. Furthermore, the bottom of the stiffening plate 6 is spaced from the bottom of the side wall panel 3, allowing it to overlap the upper flange 81 of the main steel beam 8, thus improving the compatibility of the bathroom formwork with the prefabricated steel structure. The stiffening plates 6 are spaced circumferentially along the outer wall surface of the side wall panel 3 and perpendicular to it, avoiding any pre-drilled door or window openings on the side wall panel 3.

[0035] In one embodiment, the embedded angle steel 5 is fixedly connected to the side wall plate 3 and also fixedly connected to the bottom end of the stiffening plate 6. When the bottom end of the stiffening plate 6 rests on the upper flange 81 of the steel beam 8, the embedded angle steel 5 is welded to the upper flange 81 of the steel beam 8.

[0036] In this embodiment, the first vertical steel plate of the pre-embedded angle steel 5 is embedded in the side wall plate 3, and the second horizontal steel plate protrudes from the outer wall surface of the side wall plate 3. The lower end face of the second steel plate is in the same plane as the lower end face of the stiffening plate 6. Before the concrete pouring of the bathroom formwork in the factory, the pre-embedded angle steel 5 is pre-installed in the template of the bathroom formwork. After the concrete of the bathroom formwork hardens, the pre-embedded angle steel 5 forms a fixed connection with the stiffening plate 6 and the side wall plate 3. The number of pre-embedded angle steel 5 is the same as the number of stiffening plates 6, and they correspond one-to-one. Besides serving to weld with the upper flange 81 of the steel beam 8 of the main building structure, the pre-embedded angle steel 5 also strengthens the stiffening plate 6 and the side wall plate 3, preventing cracking. Specifically, since the stiffening plate 6 overlaps the upper flange 81 of the steel beam 8, without the pre-embedded angle steel 5, the joint connecting the bottom of the stiffening plate 6 and the side wall plate 3 will experience significant stress under vertical loads, potentially leading to cracking.

[0037] In one embodiment, the lower flange 82 of the steel beam 8 is longer than the upper flange 81, and the rib beam 4 is mounted on the lower flange 82.

[0038] In this embodiment, a specific method is provided for the connection between the rib beam 4 and the steel beam 8 of the building structure: the lower flange 82 of the steel beam 8 is extended to be longer than the upper flange 81. Therefore, the bathroom formwork can be hoisted onto the steel beam 8 from top to bottom between adjacent steel beams 8. The two ends of the rib beam 4 overlap the upper end surfaces of the adjacent lower flanges 82 of the two steel beams 8. The adjacent ends of the upper flanges 81 of the two steel beams 8 can play a certain role in horizontally limiting the side wall panel 3 of the bathroom formwork. At the same time, the stiffening plate 6 with the embedded angle steel 5 is overlapped onto the upper flange 81 of the steel beam 8, and the embedded angle steel 5 and the upper flange 81 of the steel beam 8 are welded together. If the height of the steel beam 8 cannot meet the requirement that the rib beam 4 overlaps the lower flange 82, the stiffening plate 6 can just overlap the upper flange 81. In this case, a heightening pad 10 can be welded onto the upper end surface of the lower flange 82 of the steel beam 8 before hoisting the bathroom formwork.

[0039] In one embodiment, a rib beam 4 support plate is fixedly connected to the web plate 83 of the steel beam 8. The rib beam 4 support plate is located below the upper flange 81, and the length of the rib beam 4 support plate is greater than the length of the upper flange 81. The rib beam 4 rests on the rib beam 4 support plate.

[0040] In this embodiment, another specific method is provided for the connection between the rib beam 4 and the steel beam 8 of the main building: a rib beam 4 support plate is welded to the web plate 83 of the steel beam 8. The length of the rib beam 4 support plate is greater than the length of the upper flange 81, where the length of the upper flange 81 refers to the distance from the end of the upper flange 81 to the web plate 83. Therefore, the bathroom formwork can be hoisted onto the steel beam 8 from top to bottom between adjacent steel beams 8. The two ends of the rib beam 4 overlap the upper end surface of the rib beam 4 support plate of the two steel beams 8, and the close ends of the upper flanges 81 of the two steel beams 8 can play a certain role in horizontally limiting the side wall panel 3 of the bathroom formwork. At the same time, the stiffening plate 6 with the embedded angle steel 5 is overlapped on the upper flange 81 of the steel beam 8, and the embedded angle steel 5 and the upper flange 81 of the steel beam 8 are welded together.

[0041] In one embodiment, such as Figure 3 and Figure 4 As shown, alternatively, the length of the lower flange 82 of the steel beam 8 at one end of the rib beam 4 can be greater than the length of the upper flange 81, and a rib beam 4 support plate with a length greater than the upper flange 81 can be welded to the web plate 83 of the steel beam 8 at the other end of the rib beam 4. The upper end face of the rib beam 4 support plate is in the same plane as the upper end face of the lower flange 82 of the steel beam 8 at the other end of the rib beam 4, or the upper end face of the rib beam 4 support plate is in the same plane as the upper end face of the raising pad 10 on the lower flange 82 of the steel beam 8 at the other end of the rib beam 4, so that the rib beam 4 can be horizontally overlapped on the steel beam 8.

[0042] In one embodiment, a first electromechanical pipeline is laid in the space between adjacent stiffening plates 6, and an interface for the first electromechanical pipeline is reserved. The electromechanical system can be used on-site after only connection. Rock wool and decorative panels are laid on the outside of the first electromechanical pipeline, and the rock wool and decorative panels form the wall insulation system 7, thereby filling the space between adjacent stiffening plates 6 to ensure the flatness of the outer wall surface of the bathroom formwork. This process is carried out in the factory. Thus, during on-site construction, it is only necessary to connect the electromechanical system according to the reserved interface, without having to make holes in the wall panels of the bathroom formwork to install internal pipelines, reducing on-site construction procedures. That is, in this embodiment, the stiffening plates 6 can not only improve the strength of the side wall panels 3 and provide the connection point with the steel beams 8 of the main building, but also provide space for the pre-installation of electromechanical pipelines without opening pipeline layout channels in the walls of the bathroom formwork, reducing construction procedures while improving the integrity and waterproof performance of the bathroom formwork.

[0043] In one embodiment, the top plate 2 is provided with a second electromechanical pipeline, for example, the second electromechanical pipeline is fixed to the top plate 2 by a back bolt.

[0044] This invention also provides a bathroom module, including an interior system and the bathroom mold shell described in the above embodiments; the interior system is fixed in the space inside the bathroom mold shell.

[0045] In this embodiment, the built-in system refers to non-movable bathroom fixtures, such as toilets and washbasins, which can be integrated into the bathroom mold shell during factory prefabrication to form a complete bathroom module.

[0046] This invention also provides a construction method for a bathroom module, used for constructing the bathroom module described in the above embodiments. The construction method includes: After the steel beams of this floor are installed in the main building structure, the bathroom module of this floor is hoisted onto the steel beams of this floor; wherein the rib beam overlaps the steel beams of this floor.

[0047] In this embodiment, after the steel beams of this floor in the main building are installed, the hoisting stability and installation can be ensured by using a combination of jigs and jacks. According to the positional and connection relationships described in the above embodiment, the ribs, stiffening plates and embedded angle steel of the bathroom module are hoisted onto the steel beams of this floor. For example, the ribs are lapped on the lower flange and / or rib support plate of the steel beams of this floor, and the stiffening plates and embedded angle steel are lapped on the flanges of the steel beams of this floor.

[0048] The embedded angle steel is welded to the steel beam of this layer.

[0049] In this embodiment, after the bathroom module on this floor is hoisted onto the steel beam on this floor, the pre-embedded angle steel of the bathroom module is welded to the upper flange of the steel beam on this floor to stably connect the bathroom module and the main building.

[0050] Install the steel beams for the next floor.

[0051] In this embodiment, after the toilet modules on this floor are hoisted and connected, the steel beams on the floor above are installed. This avoids the pre-installation of the steel beams on the previous floor affecting the hoisting path of the toilet modules on this floor. This process is repeated upwards in a cyclical manner to complete the installation of the toilets in the entire building structure.

[0052] In summary, the bathroom formwork, modules, and construction method provided in the embodiments of the present invention have at least the following advantages: 1. High construction efficiency: The prefabricated bathroom modules only require assembly and connection to the steel structure on site, which greatly reduces on-site construction procedures and shortens the construction period; 2. Good adaptability: Through standardized and refined connection design, it can be perfectly combined with prefabricated steel structures, ensuring the stability and reliability of the connection; III. Significantly Improved Performance: The use of high-performance materials in a single molding process greatly reduces leakage problems and improves fire resistance. IV. Significant life-cycle benefits: Reduced maintenance costs such as waterproofing measures result in significant economic benefits throughout the entire life cycle; V. Rational Space Utilization: The structure and layout of the bathroom modules are optimized by combining the characteristics of prefabricated steel structures, fully integrating with the building envelope system, reducing space waste, and improving the comfort of bathroom use.

[0053] VI. Significantly Reduced Module Weight: By using high-performance materials, the size of components is greatly reduced, resulting in a lower weight for the same module, which reduces the difficulty and cost of hoisting.

[0054] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
