Description

Technical Field

[0001] This invention relates to prefabricated building systems and methods for constructing residential structures using standardized steel component kits manufactured according to a predetermined operational plan, designed to overcome the limitations of traditional concrete / brick, timber housing construction methods, and modern lightweight steel keel modular systems. Specifically, the invention provides a steel-based structural frame consisting of ten precision-machined components, designed for mass production in a dedicated manufacturing facility, optimizing transportation, and enabling rapid on-site assembly.

[0002] This system employs a predetermined sequence of manufacturing steps, such as laser-guided cutting and robotic welding, improving construction tolerances currently available in the market. These components are designed to be readily available, enabling streamlined production cycles, efficient warehousing, and direct delivery to construction sites.

[0003] The "kit-based" approach of this invention allows builders to configure structures with different dimensions, roof slopes, and disaster resistance levels (e.g., in bushfire or cyclone zones) using standardized components, eliminating delays associated with custom manufacturing and ensuring early structural waterproofing for continuous construction of interior works. The components are designed to be compatible with conventional building equipment and can be installed within days of site preparation via simple steel-to-steel bolt connections, eliminating the need for welding. This system facilitates industrialized production for bulk sales and warehouse distribution. Technical Background

[0004] Residential construction has traditionally relied on timber framing and on-site fabrication, processes inherently constrained by the natural variability of timber, weather dependence, and labor-intensive workflows. While timber is widely used, it suffers from dimensional inconsistencies due to warping, shrinkage, and moisture sensitivity, often requiring extensive rework such as shim adjustments, recutting, or refitting to achieve structural alignment. These adjustments consume significant labor time and frequently result in defects such as uneven walls, misaligned pipes, and damaged or failed waterproofing seals.

[0005] Traditional concrete and masonry construction is constrained by sequential on-site workflows, such as bricklaying, formwork erection, and concrete curing. These processes require specialized, labor-intensive techniques and are prone to material waste due to on-site adjustments, hindering project timelines. The variability of manual processes impacts quality control and poses a risk of structural inconsistencies. Weather disruptions can delay curing and scheduling, and design changes during construction can result in substantial rework costs. Masonry systems require regular maintenance, such as grouting, while concrete structures necessitate expensive reinforced concrete foundations. These factors collectively reduce scalability, cost-effectiveness, and long-term viability to meet contemporary building requirements.

[0006] Modular construction emerged to address these inefficiencies, namely the off-site prefabrication of components. However, most modular systems employ rigid, non-reconfigurable designs, limiting architectural creativity to repetitive layouts. Fixed dimensions lead to material waste during manufacturing, as unused portions of components are discarded, and restrict adaptability to specific site requirements. Furthermore, existing precast steel systems often rely on on-site welding or custom manufacturing for non-standard designs, offsetting the time-saving advantages of prefabrication. Builders also face the challenge of a shortage of skilled workers, particularly in specialized areas such as welding.

[0007] Open-air construction exacerbates these challenges. Traditional construction cycles are easily affected by rain, strong winds, or extreme temperatures, which can halt concrete curing, delay roof construction, or damage parts of the completed structure. Even modular systems, while reducing on-site time, often fail to achieve early waterproofing and sealing, leading to delays in interior finishing work. The prefabricated modular system proposed in this invention fills a significant gap in the construction industry market by providing the following advantages:

[0008] Flexibility and scalability: This prefabricated system is both flexible and scalable, allowing for adjustments to building dimensions by using load-bearing corner components and then installing other components, including different floor heights, floor slabs, roof and wall spans, and roof slopes, to accommodate a variety of building designs and layouts.

[0009] Material variability: The system reduces alignment issues by using precision-manufactured steel components, ensuring quality during construction.

[0010] Reduced reliance on skilled workers: Through bolted connections and standardized assembly, the system allows semi-skilled workers to assemble the components, minimizing the need for specialized labor.

[0011] Accelerate construction time: The system can achieve structural closure within days of site preparation, provide waterproof protection for the building envelope, and allow interior finishing work to proceed uninterrupted.

[0012] Minimize waste: Using prefabricated components reduces on-site scraps, thereby minimizing waste.

[0013] Ensuring quality control: Exposed bolt connections facilitate visual inspection, reduce the risk of fasteners loosening, and ensure quality throughout the assembly process. Summary of the Invention

[0059] All precast steel components are coated with appropriate surface anti-corrosion protection according to environmental durability requirements, including but not limited to hot-dip galvanizing, zinc-rich coatings, protective and rust-preventive paints, corrosion-resistant alloys, and sacrificial anodes.

[0060] The assembly station is configured to use open-end locking fasteners (such as nuts and bolts) and screw connections to bolt sub-components together as finished products.

[0061] In one implementation, the system delivers components of a defined size to an assembly station in a pre-arranged sequence to achieve error-free assembly.

[0096] Detailed description of the implementation example:

[0097] This invention discloses a prefabricated steel structure system for building construction, comprising ten precision-machined, standardized components with dimensional accuracy exceeding that of traditional timber frame structures. The system integrates a modular component system optimized for automated mass production, efficient logistics, and rapid on-site assembly. Components can be packaged into flat-pack modules compatible with ISO container shipping, with a maximum width of 2.4 meters, simplifying global logistics. On-site assembly employs a bolted connection sequence method, where pre-drilled connection points and slots enable rapid structural integration.

[0098] This disclosure provides a detailed description of the structural and functional configurations of individual components, assemblies, and the overall building structure. In one embodiment, the modular system is configured to form foundation assemblies, floor assemblies, wall assemblies, or roof assemblies according to the desired building layout. In a further embodiment, the system includes two or more interconnected building assemblies that combine to form a complete building assembly, offering flexibility to adapt to various design requirements and spatial configurations. The system enables both isomorphic and heterogeneous configurations to meet diverse architectural and environmental needs. Isomorphic configurations utilize uniform modules (such as solid wall panels) to accelerate repetitive assembly in standardized layouts. Conversely, heterogeneous configurations integrate hybrid modules—such as alternating solid wall units and perforated units with prefabricated doors and windows—to accommodate customized architectural features. This modular system allows for customization and reconfiguration to meet a wide range of architectural needs.

[0099] Basic system components

[0100] The foundation system is designed as a steel frame structure, providing a robust and adaptable base for construction. It comprises 200×100×3mm thick rectangular hollow tubular profiles as the main frame components, and 100×50×3mm C-shaped channel steel. These components are precision-machined with chamfered slots (100mm long × 50mm wide) to allow concrete flow, ensuring a void-free and honeycomb-free composite concrete foundation slab. This innovative design eliminates the need for traditional formwork or strip foundations, simplifying the construction process. The secondary frame is achieved through C-shaped lightweight steel keel beams, which interconnect with right-angle braces to ensure precise 90-degree alignment during assembly. The system also integrates leveling components for fine-tuning the foundation's levelness, and incorporates a steel mesh and distribution reinforcement underneath to enhance load distribution and improve overall structural stability.

[0101] The assembly process begins with site preparation, followed by the installation of the steel frame system on deep foundation supports such as helical piles or cast-in-place piles. Horizontal right-angle platform supports and vertical / horizontal adjustment components are used to level the ground and ensure accurate alignment during assembly. A waterproof membrane is laid on compacted soil or ground. Steel components are connected using a simple bolt and self-tapping screw method, eliminating the need for on-site welding and significantly reducing construction time and costs. Once the steel frame platform is fully assembled, a reinforcing mesh is installed on top, with additional distribution reinforcement placed below. Concrete is then poured directly into the frame, filling the chamfered slots to solidify the structure and ensure seamless integration of the steel and concrete elements.

[0102] This foundation system offers several key advantages. By integrating the steel frame and concrete pouring into a single step, it eliminates the need for traditional formwork and strip foundations, simplifying the construction process. The chamfered holes in the steel tubes facilitate concrete pouring and spreading, improving structural integrity while maintaining efficiency. The use of C-beams, rectangular tubular profiles, and bolted connections ensures rapid and accurate assembly without on-site welding, further reducing labor requirements and shortening project cycles. Furthermore, the system is compatible with a variety of deep foundation solutions, including helical piles and cast-in-place piles, making it suitable for diverse soil conditions. Features of precision construction, such as right-angle bracing and three-dimensional leveling, ensure accurate alignment and provide a stable working surface for subsequent construction phases.

[0103] This advanced framed steel foundation system represents a versatile and efficient solution for modern construction. It provides a robust, level base that can be custom-designed to suit various building layouts while minimizing on-site scrap, avoiding material waste, reducing labor costs, and eliminating environmental impact. Its adaptability, precision, and ease of assembly make it ideal for rapidly constructing structurally reliable projects.

[0104] Wall components

[0105] The wall component system utilizes a linear grid frame composed of individual panel wall components arranged in a vertical configuration to ensure uniform load distribution and lateral stability. Each panel contains longitudinal and transverse members that are discretely manufactured and assembled, rather than relying on continuous members. These members are designed to adapt to architectural features, such as window sills or lintels, through precise segmentation, allowing for functional and aesthetic flexibility while ensuring structural integrity. Openings or openings are strategically integrated into the panels, their perimeters defined by reinforcing members to maintain load-bearing capacity. Load-bearing corner wall components play a crucial role in securing all corners of the building, providing lateral and vertical support to stabilize the structure and ensure alignment. This modular approach enables seamless integration of windows, doors, utilities, or decorative elements, offering a highly adaptable and precise solution to meet diverse design needs.

[0106] Load-bearing corner wall components

[0107] The load-bearing corner wall assembly is a key structural element designed to secure building corners while providing lateral and vertical support. Ensuring structural stability and alignment, the assembly, with standard dimensions of 600mm wide and 2700mm high, features integrated diagonal bracing for enhanced rigidity. Height can be customized to meet specific project requirements. Manufactured from 100×100×3mm thick square and rectangular tubular profiles as vertical members, 100×100×3mm thick C-channel steel (laid flat) as top and bottom horizontal members, and 100×50×3mm thick rectangular hollow profiles as diagonal bracing members, this assembly is designed for durability and precision.

[0108] Prefabricated and welded in the workshop to ensure consistent quality, the component is bolted to the top slab, bottom slab, or foundation system. The ring beam modules connect all load-bearing corner wall components, fixing the building's dimensions. Both vertical and diagonal members are pre-drilled with through holes for seamless integration of service piping, such as conduits and electrical wiring, during installation. A key advantage of this component is its ability to define and stabilize the overall dimensions of the structure, providing flexibility and scalability to meet diverse design requirements.

[0109] Rectangular wall load-bearing components

[0110] The rectangular wall load-bearing component serves as the primary vertical support element within the wall structure, ensuring the structural integrity of the building envelope. The standard dimensions are 600mm wide and 2700mm high, but the component height can be adjusted to meet customer specifications. It utilizes 100×100×3mm thick square and rectangular tubular profiles as vertical members and 100×100×3mm thick C-shaped channel steel (laid flat) as top and bottom horizontal members. The component is bolted to the top slab, bottom slab, or foundation frame.

[0111] To achieve additional lateral stability, diagonal bracing similar to that used in load-bearing corner wall assemblies can be incorporated when needed. Prefabricated and welded in the workshop, this assembly ensures precise alignment and ease of on-site installation. Vertical members are pre-drilled to accommodate service piping, including conduits and electrical wiring, ensuring compatibility with building services. These assemblies are installed at standard intervals of approximately 1400mm after the load-bearing corner wall assemblies and top slab are placed to ensure uniform load distribution and structural continuity.

[0112] Door and window load-bearing components

[0113] The door and window load-bearing components are specially designed to provide vertical support while allowing openings for windows and doors. The standard height of the component is 2700mm, and the width can be customized to fit the dimensions of the door or window. The height can also be adjusted to meet specific customer requirements.

[0114] The structure is constructed using 100×100×3mm thick square and rectangular tubular profiles as vertical members (for door and window frames), 100×100×3mm thick square and rectangular tubular profiles as horizontal members for lintels and sills, and 100×100×3mm thick C-shaped channel steel (laid flat) as top and bottom horizontal members. This assembly is bolted to the top plate, bottom plate, or foundation frame. Vertical intermediate members are installed to support the sill members, depending on the width of the opening.

[0115] Prefabricated and welded in the workshop to ensure precision, the components are ensured to align accurately during installation. Vertical members are pre-drilled to allow for the integration of service piping, such as conduits and electrical wiring. In areas subject to high wind loads, such as cyclone zones, vertical members can be upgraded to 200×100×3mm thick square and rectangular tubular profiles to enhance structural resilience. These components are installed in designated locations within the wall components after the load-bearing corner wall components and roof slab are secured, ensuring seamless integration into the overall structural frame.

[0116] The installation process begins with securing the load-bearing corner wall components to the main steel frame using anchor bolts. These components form the structural anchor points at the building corners, laying the foundation for subsequent assembly steps. The top plate is then installed, connecting all the load-bearing corner wall components to ensure proper alignment and continuity of the structure.

[0117] After the top slab is in place, the rectangular wall load-bearing components and door and window load-bearing components are installed in their respective positions. These components are positioned at standard intervals of approximately 1400mm to ensure uniform load distribution and structural stability.

[0118] Once the load-bearing components and the first-floor ribbed beams are installed, the internal molded ceramic panels are mechanically secured to the wall modules using structural adhesive. After the interior rough finishing is completed, the external molded ceramic panels are then secured to the wall modules in a similar manner.

[0119] This wall component system combines prefabrication, modular design, and precision construction, providing a versatile and reliable solution. By integrating a linear grid structure with customizable openings and perforations, the system meets the needs of modern building projects while ensuring compliance with structural and performance standards.

[0120] Floor slab components

[0121] The floor system is designed to provide a robust and adaptable framework supporting the single-story structure, ensuring compatibility with various load requirements and building configurations. At its core are the first-floor ribbed beams, precision-constructed from 400×100×3mm thick C-shaped steel. These steel beams serve as the primary load-bearing elements of the floor components, with pre-drilled through-holes in the web to seal through equipment ducts, mechanical air ducts, and other building pipelines. Mounted to the upper surface of the floor using self-tapping screws, the ribbed beams are spaced 700mm apart at the centerline, a spacing that can be adjusted—reduced to 450mm or increased to 750mm—to accommodate specific design floor loads. Standard beam lengths of 6m, 9m, and 12m are available, and custom cuts can also be made to fit unique floor plans. For areas subjected to higher concentrated loads, such as heavy fixtures or equipment, double beams—a reinforcement method achieved by pairing two beams together—can be implemented to enhance load-bearing capacity. Extra-long joists can be specially ordered to meet specific project requirements. Furthermore, it directly anchors the ceiling—an 8mm thick aluminum honeycomb panel—eliminating the need for a suspended ceiling.

[0122] Supporting the ribbed floor slabs are ring beam modules, consisting of a top and bottom slab made of 100×100×3mm thick rectangular tubular profiles. The top slab is supported by load-bearing components below, while the bottom slab is securely mounted to the ribbed floor slabs. These slabs play a crucial role in stabilizing the overall structure, providing lateral restraint to reduce instability in the walls and floor slab supports. For areas with cantilever requirements, such as roofs or balconies, the cross-sectional dimensions of the top and bottom slabs can be upgraded to 200×100×3mm thick rectangular tubular profiles, ensuring enhanced load-bearing capacity and structural stiffness.

[0123] The installation process begins by positioning the first layer of ribbed floor slab beams on the upper surface of the top slab and securing them with self-tapping screws at specified intervals. The spacing is adjusted according to the anticipated floor load to ensure optimal performance and safety. Subsequently, the base plate is installed on top of the ribbed floor slab beams, paying particular attention to alignment and connection to ensure stability and support for subsequent construction phases. For the first-floor walls, the installation process is the same as the construction steps outlined in the wall component system overview, including placing the load-bearing corner wall components, top slab, and other wall components.

[0124] Structural waterproofing in damp areas (e.g., balconies) is achieved by creating a height difference between the interior and exterior floors by varying the material thickness of the interior dry areas, damp areas, and exterior floor slabs. The interior floor slab thickness in damp areas such as bathrooms and balconies is 50mm, while other interior floor slabs are 75mm. A 1mm thick Z-shaped metal strip covers the floor slab at the height difference to ensure waterproofing. This low-risk technique protects steps from water intrusion because it does not overly rely on easily aging and failing flexible waterproofing materials.

[0125] The floor system integrates seamlessly with the wall component system, providing a flexible and scalable solution for single-story construction that can be easily adjusted to accommodate different floor plan dimensions.

[0126] Roof components

[0127] The ceiling and roof system is meticulously designed to provide a robust and adaptable framework for supporting ceiling panels, roofing materials, and exterior finishes, while accommodating diverse architectural and functional requirements. At the heart of the system are the ribbed ceiling beams, constructed from 100×100×3mm thick C-shaped steel sections, serving as the primary structural members supporting the ceiling panels. Each beam is mounted to the ceiling plate using self-tapping screws, with a standard center-to-center spacing of 700mm, ensuring uniform load distribution and structural stability.

[0128] The enclosed roof structure is the eaves beam, also known as the three-in-one waterproof pipe beam, which is made of 200×100×3mm rectangular hollow profiles and supported by the roof slab.

[0129] The eaves beam fulfills several key functions, serving as the finishing point for the externally molded ceramic 2700×600mm wall panels and providing crucial support for the roof drainage system. Furthermore, it plays a key role in the innovative roof waterproofing system, enhancing the overall structure's durability and weather resistance.

[0130] The roof rafters are constructed from 100×100×3mm square and rectangular tubular profiles, installed at standard 800mm intervals and connected to the eaves beams, effectively acting as roof trusses. These rafters are designed with an adjustable slope ranging from 5 to 11 degrees, allowing for customization to meet specific roof design requirements. Installed using self-tapping screws, the rafters provide a stable framework for securing roofing materials, including the waterproofing underlay and insulation, ensuring thermal efficiency and effective weatherproofing.

[0131] The installation process begins with securely attaching the ceiling ribbed beams to the roof slab, ensuring precise alignment and consistent spacing. Subsequently, the perimeter fascia beams are installed using specialized connectors, securing them in place as structural and aesthetic elements. The ceiling ribbed beams are fixed to the fascia beams using 70×100×1.5mm steel brackets. Additionally, 300×100×1.5mm steel brackets are fixed to the fascia beams to connect the roof rafters. These are positioned and secured in place with self-tapping screws, maintaining the specified spacing and slope. Roofing materials, including a waterproofing underlay and insulation layer, are applied to the rafter frame to complete the roof assembly.

[0132] Once the structural framework is finalized, the system is completed by installing interior wall panels, exterior molded ceramic panels, and floor panels. The seamless integration of the ceiling, roof, and wall systems ensures a coherent solution tailored to the needs of modern architecture.

[0133] Molded ceramic panel system

[0134] This kit integrates non-load-bearing molded ceramic panels as components of load-bearing walls, interior walls, and floors, providing a lightweight, durable, and versatile solution for modern architecture. These molded ceramic panels are designed to be non-combustible, waterproof, and insulating, making them ideal for residential applications. Available in rigid panel thicknesses of 50mm, 75mm, and 100mm, the panels are designed to achieve a standardized 300mm finished wall thickness when installed on load-bearing components. The panels incorporate non-combustibility, waterproofing, and insulation, ensuring performance and safety under various environmental conditions.

[0135] For ease of maintenance and redecoration, the molded ceramic panels are secured to load-bearing components using mechanical fasteners, enabling tool-free removal and reinstallation without compromising structural integrity. This feature enhances the system's adaptability, allowing for efficient updates or repairs throughout the building's lifespan.

[0136] In interior wall applications, molded ceramic panels are vertically fixed between floor ribs and ceiling panels to form wall components with standard dimensions of 600mm wide and 2700mm high. These panels are fixed to the bottom of the floor slab and the top of the ceiling or floor ribs, providing a seamless and rigid interior wall finish. For floor applications, molded ceramic panels are installed directly onto the floor ribs, forming a strong, waterproof, and thermally insulated surface, ideal for residential use.

[0137] The standard panel size is 600mm × 1400mm, ensuring compatibility with the grid framework of wall and floor slab component systems. When used as an exterior or interior veneer, the molded ceramic panels are fixed to load-bearing components, serving as a durable and aesthetically pleasing wall finish. Their versatility, combined with their compliance with key Australian standards, makes these molded ceramic panels a reliable and high-performance solution for contemporary building projects.

[0138] Construction method and process:

[0139] 1. Site preparation and foundation

[0140] This includes leveling the ground, compacting the soil, and marking out the lines. Based on the marked locations, install helical piles with diamond-shaped elongated holes, ensuring that the elevation accuracy of all pile heads is within a tolerance of + / - 10mm.

[0141] The basic frame assembly begins by installing 200×100mm rectangular hollow tube profiles into the helical piles, using a horizontal right-angle platform to support the brackets and tightening them with screws to align the tubes.

[0142] The distributed reinforcing bars are placed through the through holes in the steel web, followed by the laying of the top reinforcing mesh to control cracking, and then concrete is poured, laid flat, compacted and smoothed.

[0143] 2. Installation of the underlying structural walls

[0144] First, install all 600×600mm load-bearing corner components and bolt them to the foundation. Next, install the ring beam module—a 100×100mm top plate—to secure all load-bearing corner components, ensuring proper alignment and continuity of the entire structure. Following this, install the rectangular load-bearing wall components and door / window load-bearing components in their respective positions. Once the structural components are installed and secured, install the internal molded ceramic panels, followed by the external molded ceramic panels.

[0145] 3. Assembly of the first-floor ribbed beams

[0146] Secure the 400×100mm C-beams with pre-drilled holes for equipment piping to the previously installed top plate at 700mm intervals. Next, install the secondary 100×100mm top plates and bolt them to the C-beams. Figure 9 This demonstrates the relationship between the ribbed floor beams and the ring beam modules.

[0147] 4. Installation of the first-floor structural walls

[0148] The installation follows the same method as the underlying structural walls: first install the load-bearing corner components, then the roof slab, followed by the load-bearing wall components and door / window load-bearing components. Similarly, once the structural components are installed and secured, the internal molded ceramic panels can be installed, followed by the external molded ceramic panels.

[0149] 5. Installation of ceiling ribbed beams, eaves beams, and drainage ditches

[0150] This includes a 100×100mm C-shaped ribbed ceiling beam, bolted to the ceiling slab, and then fixed to a 200×100mm rectangular steel fascia beam via a 70×100×1.5mm steel bracket. The eaves drain is then fixed to the fascia beam.

[0151] 6. Roof rafter installation

[0152] This involves fixing 100×100×3mm square and rectangular steel tubes spaced 800mm apart to the eaves beam (a three-in-one waterproof pipe beam integrated with the eaves slab drainage ditch) using 300×100×1.5mm steel brackets, with an adjustable slope range of 5 to 11 degrees. A 300mm wide and 1.5mm thick adjustable ridge cap is used to fix the roof rafters, followed by the installation of the waterproof layer, insulation layer, and metal roofing panel.

[0153] Innovation Summary:

[0154] The modular system introduces a revolutionary approach to building construction, combining precision-machined steel components with design principles derived from traditional timber framing. The system comprises ten standardized modules, enabling large-scale storage, rapid assembly, and reconfigurability of the building / structure from single-story to multi-story structures. Components are bolted together instead of welded on-site, reducing labor and enabling rapid installation, thus shortening the time to achieve a fully enclosed, weatherproof system. This also allows for simultaneous work by internal and external trades. This innovation combines traditional craftsmanship with modern efficiency, providing a scalable and sustainable solution for building construction.

[0155] The component flat-panel packaging into modules compatible with ISO containers (maximum width 2.4m) simplifies global logistics. The system's ten standardized modules enable rapid on-site assembly, reducing delivery time compared to conventional methods.

[0156] Compared to traditional timber framing, light steel keel framing, and modular structures, the wall system's assembly sequence is innovative. It allows for minimal on-site work by a small number of workers. The wall assembly sequence begins with corner components at the building's corners, extending to the outer perimeter walls of the entire building as the upper floors are installed, followed by the infill of rectangular and door / window modules. This innovative wall assembly method reduces installation time and minimizes on-site risks, waste, and debris compared to traditional framing methods.

[0157] The foundation system replaces traditional formwork and strip foundations with rectangular tubular steel sections (200×100×3mm RHS) and C-shaped steel beams (100×50×3mm C-channel steel), along with chamfered slots on the components, allowing concrete to be poured directly through the openings. The frame integrates a reinforcing mesh and leveling components for alignment with deep foundation systems (e.g., helical piles, cast-in-place piles), simplifying site preparation.

[0158] Structural waterproofing in damp areas, such as balconies, is achieved by creating a height difference through variations in the material thickness of the internal floor slabs, the damp areas, and the external floor slabs. The thickness of the internal floor slabs and those in damp areas like bathrooms and balconies is 50mm, while other internal floor slabs are 75mm thick. A 1mm thick Z-shaped metal strip covers the floor slabs at the height difference to ensure waterproofing. This low-risk approach protects the steps from water intrusion by avoiding over-reliance on easily aging and failing flexible waterproofing materials.

[0159] The roof system uses rectangular hollow steel sections (200×100×3mm RHS) as perimeter beams to secure the drainage gutters and prevent water accumulation and overflow. Adjustable rafters (100×100×3mm SHS, 5°–11° slope) ensure compatibility with different architectural styles.

[0160] The open-plan structure has no internal load-bearing walls, relying entirely on external wall support, coupled with long-span C-shaped floor slabs and closely spaced ribbed beams. This design allows for unrestricted layout of rooms, kitchens, and bathrooms. Precast wall components (600×2700mm) integrate molded ceramic panels (non-combustible, waterproof, and weatherproof) and a central 100mm steel pipe, matching the width of standard brick-finished walls. The molded ceramic panels act as a waterproof barrier, with a 100mm wide cavity between the outer and inner panels, eliminating the need for a waterproofing layer and allowing for quick installation using structural adhesive and screws.

[0161] Aluminum alloy doors and windows are anchored to a 140mm wide subframe, employing structural waterproofing technology to ensure compliance with wind load requirements. Pre-drilled through holes in the steel beams and walls ensure the airtight passage of equipment pipelines.
