Description

Technical Field

[0001] This invention relates to a modular, quick-assembly, integrated construction and installation system. Background Technology

[0002] In recent years, with the continuous advancement of industrialized construction and green building concepts, modular and prefabricated building systems have gained widespread attention and application due to their advantages in improving project quality, shortening construction periods, and reducing environmental pollution. These building systems aim to transfer a large amount of on-site construction work to factories, improving the overall performance and construction efficiency of buildings through standardized design, factory production, and prefabricated construction.

[0003] Existing modular building technologies typically involve prefabricating structural frames, enclosure panels, and other components into unit modules in a factory, and then transporting them to the site for hoisting and assembly.

[0004] Prefabricated buildings involve the on-site assembly of individual components, and the construction and decoration teams arrive at the site sequentially to carry out construction work, which presents the following technical problems:

[0005] The complex connection nodes of the modules necessitate improvements in installation efficiency and accuracy: Existing systems rely on on-site welding or complex connectors for module connections. On-site welding is highly susceptible to weather and worker skill levels, making quality control difficult, and also poses fire hazards and environmental pollution. Some mechanical connection methods are either difficult to position, requiring extremely high installation precision, resulting in time-consuming and labor-intensive hoisting; or have insufficient connection strength and rigidity, affecting overall structural performance; or have complex structures, hindering later maintenance and modifications.

[0006] Insufficient system integration and numerous overlapping on-site procedures: Some systems only achieved modularization of the main structure, while the roofing, flooring, and exterior wall systems still required multiple on-site splicing, filling, and finishing processes. For example, the flooring system may still require on-site pouring of the subbase and laying of insulation and waterproofing materials; the exterior wall system may require on-site installation of the framework followed by sequential filling of the insulation layer and installation of interior and exterior decorative panels. This phased construction method fails to fully utilize the advantages of factory prefabrication, resulting in a large amount of on-site work, limited timeline reduction, and easy interference between different trades, affecting the final quality and protection of the finished product.

[0007] There are shortcomings in the connectivity of key subsystems:

[0008] Connection between structural frame and foundation: Traditional column base connection often requires precise on-site measurement before welding or pouring, which is not only slow to construct but also difficult to adjust, and has stringent requirements for the accuracy of foundation embedded parts.

[0009] Rapid sealing and waterproofing of roofing systems: Improper handling of the splicing joints of roofing modules can easily become potential leakage points. Furthermore, the insulation, waterproofing, and structural layers of the roof are constructed in layers on site, making it difficult to guarantee their integrity and continuity.

[0010] Multifunctional integration and rapid installation of exterior wall systems: Existing prefabricated exterior wall panels often have only one function (such as load-bearing or only insulation), requiring on-site assembly to achieve multiple functions such as load-bearing, insulation, and decoration. Their connection to the main structure often relies on welding or a large number of bolts, which is inconvenient to install, and the sealing, waterproofing, and thermal bridging of the panel joints are also difficult points in on-site construction.

[0011] Furthermore, existing modular buildings still face challenges in transportation: the overall module size is often limited by roads and transportation vehicles, preventing the full realization of the economies of scale advantages of factory prefabrication. If disassembled components are transported, the on-site assembly workload increases, negating the efficiency advantages of modularity. Particularly in terms of exterior wall systems, if prefabricated wall panels are used, their size and shape are often restricted by transportation, making it difficult to flexibly adapt to diverse building facade designs, and transportation costs are high. Summary of the Invention

[0012] The purpose of this invention is to provide a modular, quick-assembly, integrated construction system that addresses the shortcomings of existing technologies. This system not only allows for the factory processing of node frame structures, roof modules, integrated flooring systems, and composite exterior wall panels, improving processing quality, precision, and reducing defects, but also features pre-set lifting points for each module in the factory for convenient on-site installation. Furthermore, the use of high-strength, adjustable mechanical connection nodes and bolt-fixed components enables rapid positioning and fixing between modules and between modules and the main structure. On-site installation only requires lifting and connection, thus reducing the impact of weather and human factors and significantly shortening on-site operation time.

[0013] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0014] A modular, quick-assembly, integrated construction system, characterized by: comprising...

[0015] Node-based framework structure;

[0016] Roofing modules are connected to the top of the node frame structure;

[0017] An integrated ground system is connected to the bottom of the node frame structure;

[0018] Composite exterior wall panels are connected to the node frame structure and located between the roof module and the integrated floor system;

[0019] The node frame structure, roof modules, composite exterior wall panels, and integrated flooring system are assembled on-site through detachable mechanical connections to form a building system.

[0020] Through the above structural design, not only can the node frame structure, roof modules, integrated flooring system, and composite exterior wall panels be processed in the factory, improving processing quality, precision, and reducing defects, but also each module has pre-set lifting points in the factory for convenient on-site hoisting. At the same time, the use of high-strength, adjustable mechanical connection nodes and plug-in bolt-fixed component connection methods enables rapid positioning and fixing between modules and between modules and the main structure. On-site installation only requires hoisting and connection, thereby reducing the impact of weather and human factors, significantly shortening on-site operation time. The standardized height is set to accommodate container transportation, and the length can be flexibly adjusted according to the building facade requirements, improving transportation convenience and economy while ensuring functional integration.

[0021] Furthermore, the node frame structure includes a roof triangular truss, roof beams, and structural columns. The roof triangular truss is inserted into and fixed to the roof beams, the top of the structural columns is inserted into and fixed to the roof beams, and the bottom of the structural columns is inserted into and fixed to the integrated floor system. This enables rapid installation between the roof triangular truss, roof beams, structural columns, and integrated floor system. This not only reduces on-site welding and speeds up installation but also improves installation accuracy. It also meets the requirements for secondary dismantling and modification, making construction flexible and convenient, and facilitating the splicing of roof modules and composite exterior wall panels.

[0022] Furthermore, the roof beams include top beams and transition pieces. Adjacent top beams are spliced ​​and fixed together by transition pieces, which facilitates the splicing and installation of roof beams.

[0023] Furthermore, the top beam and / or adapter are fixedly connected with the first set of plugs, and the roof triangular truss is provided with the first plug rod. The first plug rod is inserted into and fixed to the first set of plugs to realize the quick installation between the roof triangular truss and the roof beam. After the first plug rod is inserted into the first set of plugs, the first plug rod and the first set of plugs are connected by the first fastener, which can improve the connection stability between the roof triangular truss and the roof beam.

[0024] Furthermore, the adapter includes at least one U-shaped snap-fit ​​component welded to the side of the top beam for connection between the end of the top beam and the side of the top beam, or two snap-fit ​​components welded to adjacent sides of the fixed column for connection between the ends of the two top beams. The ends of the top beams can be connected by the snap-fit ​​components and fixed by a third fastener, thereby improving the overall stability of the roof beam installation.

[0025] Furthermore, both the top beam and the transition piece are welded with a second insert rod through a steel plate. The second insert rod is inserted into and fixed to the structural column. It is connected to the structural column and the second insert rod by a second fastener, which can improve the stability and reliability of the connection between the structural column and the roof beam.

[0026] Furthermore, it also includes a roof chord support structure. The roof triangular truss is equipped with support ear plates. The roof chord support structure is placed on the support ear plates and fixedly connected to the support ear plates by fasteners passing through the support ear plates. This is used to achieve horizontal support for the roof triangular truss and improve the stability and reliability of the roof triangular truss.

[0027] Furthermore, the roof module includes a roof structural layer, a leveling layer, and a roof insulation layer. The roof structural layer is laid on the roof chord support structure, and a V-shaped strip is laid between two opposite roof structural layers. The roof insulation layer is connected to the top of the roof structural layer through the leveling layer, and a pressure strip is laid between two opposite roof insulation layers, with the pressure strip located above the V-shaped strip. Through the above structural design, not only is the connection strength and stability between the roof modules improved, but it also has a good waterproof effect.

[0028] Furthermore, the integrated ground system includes a chassis composite structure and column bases. The chassis composite structure includes a frame with a chassis sleeve, and the column bases include concrete foundations. The chassis sleeve and positioning components set on the concrete foundation are aligned through a mutually cooperating positioning structure and fixedly connected by bolts. This reduces on-site welding, enables fully dry operation, improves installation speed, reduces reliance on manual labor, and eliminates welding pollution and safety hazards, meeting the green and environmentally friendly requirements of building industrialization.

[0029] Furthermore, the positioning component is a column base connector. The positioning structure includes the column base connector and a through hole that runs vertically through the chassis sleeve. When the column base connector corresponds to the structural column, the column base connector has an inner core component, which is inserted into and fixed in the through hole. When the column base connector corresponds to the door, the column base connector has a connecting part, and a third fixing plate is fixed in the through hole. The connecting part supports and fixes the third fixing plate. Through the mutually cooperating positioning structure, the chassis composite structure can achieve automatic and primary accurate alignment when in place, thus solving the technical problem of difficult positioning.

[0030] Furthermore, the column base also includes a base plate, on which embedded steel bars are fixed. The embedded steel bars are embedded and fixed in the concrete foundation. The base plate and the column base connector are fixedly connected. The base plate is fixed with a positioning plate, and the column base connector is fixed on the positioning plate. A threaded column is fixed on the positioning plate, and the column base connector is sleeved on the threaded column and locked and fixed by a nut.

[0031] Furthermore, the column base connector is fixed with a support plate, which is used to support the frame, or the support plate is used to support the third fixing plate and is fixed to the third fixing plate by bolts.

[0032] Furthermore, the chassis composite structure also includes plate and frame base plate. The frame includes a first type of steel, which is fixedly connected to the chassis sleeve to form a cavity that runs vertically through the structure. The plate is fixed to the upper surface of the first type of steel to seal the upper part of the cavity, and the frame base plate is fixed to the lower surface of the first type of steel to seal the lower part of the cavity. A second type of steel is fixed between two parallel first type of steel. A steel pipe is fixed in the first type of steel. The first type of steel has a circular hole, and the steel pipe has a lifting hole, which is located below the circular hole.

[0033] Furthermore, the composite exterior wall panel includes interior decorative panels, exterior decorative panels, pipelines, junction boxes, and through-beams. The interior decorative panels and exterior decorative panels are sequentially connected by an interior baseboard, a wall structure frame, OSB boards, and extruded polystyrene insulation boards. The pipelines, junction boxes, through-beams, interior decorative panels, interior baseboard, wall structure frame, OSB boards, extruded polystyrene insulation boards, and exterior decorative panels are combined to form the exterior wall panel. This allows for modular assembly and integration of the exterior wall panel in the factory, facilitating rapid on-site installation and fixing, avoiding on-site welding work, and achieving integrated functions of load-bearing, thermal insulation, sound insulation, waterproofing, pipelines, and decoration. It is also suitable for rapid industrial installation (production assembly), fully realizing the integration of walls and pipelines.

[0034] Furthermore, it also includes connecting ear plates, through which the exterior wall panels are connected to the structural columns, improving the stability and reliability of the connection between the exterior wall panels and the structural columns; both ends of the interior base plate are provided with opening grooves to avoid the connecting ear plates.

[0035] Furthermore, the wall structure framework includes a vertical frame, a first and second set of joists, with the vertical frame distributed between them. Reinforcing blocks connect the vertical frame and the first set of joists, and these reinforcing blocks have concealed hanging points. Through holes are located on the first set of joists near these concealed hanging points. This design of the vertical frame, first and second set of joists improves the installation stability of the fireproof and soundproof panels and thermal insulation cotton, enabling modular installation and improving construction efficiency. The concealed hanging points meet the requirements for overall hoisting of the exterior wall panels. The wall structure framework ensures high strength and rigidity, and the use of a special-shaped steel frame structure to embed fireproof and soundproof panels and thermal insulation cotton internally gives the exterior wall panels excellent thermal insulation and sound insulation performance. Grooves are provided at both the top and bottom of the vertical frame to facilitate the overall push-in installation of the exterior wall, preventing collisions with the nuts at the top and bottom of the frame columns during installation and facilitating bolt adjustment.

[0036] Furthermore, X-shaped support frames are provided on the outdoor side of the vertical frame, the first and second keels, which can further improve the overall strength of the wall structure frame.

[0037] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0038] 1. This invention not only allows the node frame structure, roof modules, integrated ground system, and composite exterior wall panels to be processed in the factory, improving processing quality, precision, and reducing defects, but also allows each module to have pre-set lifting points in the factory for convenient on-site hoisting. At the same time, it utilizes high-strength, adjustable mechanical connection nodes and a component connection method with plug-in structural bolts to achieve rapid positioning and fixing between modules and between modules and the main structure. On-site installation only requires hoisting and connection, thereby reducing the impact of weather and human factors and significantly shortening on-site operation time.

[0039] 2. The node frame structure of the present invention can not only reduce on-site welding construction and speed up installation, but also improve installation accuracy. At the same time, it can meet the requirements of secondary dismantling and modification, making construction flexible and convenient, and is conducive to the splicing of roof modules and composite exterior wall panels.

[0040] 3. The integrated ground system of the present invention reduces on-site welding, realizes all-dry operation, improves installation speed, reduces reliance on manual labor, and eliminates welding pollution and safety hazards, which meets the green and environmentally friendly requirements of building industrialization.

[0041] 4. The composite exterior wall panel of the present invention can not only be modularly assembled and integrated in the factory, but also facilitates quick on-site installation and fixing, avoiding on-site welding work, and realizing the integration of load-bearing, heat insulation, sound insulation, waterproofing, pipeline and decoration functions. It is also suitable for industrialized rapid installation (production assembly) and fully realizes the integration of wall and pipeline.

[0042] 5. A standardized height is adopted to accommodate container transportation, while the length can be flexibly adjusted according to the needs of the building facade, thereby improving transportation convenience and economy while ensuring functional integration. Attached Figure Description

[0081] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0082] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0083] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0084] like Figures 1 to 2 As shown, this invention provides a modular, quick-assembly, integrated building system, comprising a node frame structure, a roof module 7, an integrated flooring system, and composite exterior wall panels 8. The node frame structure, roof module 7, composite exterior wall panels 8, and integrated flooring system are assembled on-site to form a building system via detachable mechanical connections.

[0085] like Figures 2 to 6 As shown, the node frame structure includes a roof triangular truss 1, a roof beam 4, and structural columns 2. The roof triangular truss 1, roof beam 4, and structural columns 2 are arranged sequentially from top to bottom.

[0086] The building system also includes a roof chord support structure 6. The roof triangular truss 1 is provided with support lugs 102. The roof chord support structure 6 is placed on the support lugs 102 and fixedly connected to the support lugs 102 by fasteners passing through them. This connection provides horizontal support for the roof triangular truss 1 and improves its stability and reliability. Bolts can be used as fasteners.

[0087] The roof triangular truss 1 is inserted into and fixed to the roof beam 4. The roof beam 4 includes a top beam 401 and a transition piece 402. Adjacent top beams 401 are spliced ​​and fixed together by the transition piece 402, which facilitates the splicing and installation of the roof beam 4. In this application, nine roof triangular trusses 1 are used as an example. The roof beam 4 has an overall rectangular structure. The inner side of the roof beam 4 can be connected and supported by the top beams 401 to improve the overall strength and stability of the roof beam 4.

[0088] The top beam 401 and / or the adapter 402 are fixedly connected with the first set of plug-in 403. For the installation positions of the roof triangular truss 1 on both sides, the first set of plug-in 403 is fixed to the top beam 401 and the adapter 402 by welding. For the installation position of the roof triangular truss 1 on the inner side, the first set of plug-in 403 is fixed to the top surface of the top beam 401 by welding.

[0089] The roof triangular truss 1 is equipped with a first insert rod 101. To improve the stability and reliability of the connection between the roof triangular truss 1 and the roof beam 4, the first insert rod 101 can be set along both ends and the center of the bottom of the roof triangular truss 1. By inserting and fixing the first insert rod 101 to the first set of plug-in 403, the roof triangular truss 1 and the roof beam 4 can be quickly installed. After the first insert rod 101 is inserted into the first set of plug-in 403, the first fastener 404 connects the first insert rod 101 and the first set of plug-in 403, which can improve the connection stability between the roof triangular truss 1 and the roof beam 4.

[0090] The adapter 402 includes at least one U-shaped snap-fit ​​member 407, which is welded to the side of the top beam 401 for connecting the end of the top beam 401 to the side of the top beam 401. In actual assembly, the snap-fit ​​member 407 can be welded to the inner side of the top beam 401 of the rectangular roof beam 4, and then the top beam 401 can be placed between two opposing snap-fit ​​members 407. The end of the top beam 401 is then fixed to the snap-fit ​​member 407 using a third fastener 408.

[0091] When the ends of the two roof beams 401 are connected, two snap-fit ​​pieces 407 are welded to the adjacent sides of the fixed column 406 for connection between the ends of the two roof beams 401. The snap-fit ​​pieces 407 connect the ends of the roof beams 401 and are fixedly connected by the third fastener 408, improving the overall stability of the roof beam 4 installation. After the ends of the roof beams 401 are inserted into the snap-fit ​​pieces 407, the ends of the roof beams 401 are fixed to the snap-fit ​​pieces 407 by the third fastener 408.

[0092] The top of structural column 2 is inserted into and fixed to roof beam 4. Structural column 2 can be a hollow structure.

[0093] Both the top beam 401 and the adapter 402 are welded with a second insert rod 405 via a steel plate 409. Both the first insert rod 101 and the second insert rod 405 are hollow structures.

[0094] The second insert rod 405 is inserted into and fixed to the structural column 2. The second fastener 201 connects the structural column 2 and the second insert rod 405, which can improve the connection stability and reliability between the structural column 2 and the roof beam 4.

[0095] The bottom of structural column 2 is inserted into and fixed to the integrated ground system, enabling rapid installation between the roof triangular truss 1, roof beam 4, structural column 2 and integrated ground system. This not only reduces on-site welding and speeds up installation, but also improves installation accuracy. It also meets the requirements for secondary dismantling and modification, making construction flexible and convenient, and facilitating the splicing of roof module 7 and composite exterior wall panel 8.

[0096] Roof module 7 is connected to the top of the node frame structure. Roof module 7 includes a roof structural layer 701, a leveling layer 702, and a roof insulation layer 703. The roof structural layer 701 is laid on the roof chord support structure 6. A V-shaped strip 704 is laid between two opposite roof structural layers 701. The roof insulation layer 703 is connected to the top of the roof structural layer 701 through the leveling layer 702. A pressure strip 705 is laid between two opposite roof insulation layers 703, and the pressure strip 705 is located above the V-shaped strip 704. Through the above structural design, not only is the connection strength and stability between the roof modules 7 improved, but it also has a good waterproof effect.

[0097] like Figures 7 to 17 As shown, the integrated ground system is connected to the bottom of the node frame structure. The integrated ground system includes a prefabricated chassis composite structure 55 in the factory and column bases 3 constructed on site. Through the assembly method of positioning, alignment and fastening between the two, rapid, precise and green construction is achieved.

[0098] The column base 3 mainly includes a concrete foundation 31 and a positioning component. In this embodiment, the positioning component is specifically a column base connector 32. The column base connector 32 has two implementation methods depending on the object to be connected to its upper part:

[0099] In the first embodiment, the column base connector 32 is a single plate, and the column base connector 32 has an integrally formed or welded inner core 33. The inner core 33 is usually a hollow steel pipe 5201, and its cross-sectional shape matches the through hole 5101 on the chassis sleeve 51, for example, square or circular.

[0100] Example 2: A connecting portion 34 is formed at the top of the column base connector 32. The connecting portion 34 can be a platform or a plate with connecting holes.

[0101] The column base connector 32 needs to be anchored to the concrete foundation 31 via a reliable system. Specifically, the column base 3 also includes a base plate 3101, the bottom of which is welded with multiple pre-embedded steel bars 3102. When the concrete foundation 31 is poured on site, the pre-embedded steel bars 3102 are embedded therein, thereby firmly anchoring the base plate 3101 to the concrete foundation 31.

[0102] In order to accurately install the column base connector 32, the positioning plate 3103 can be fixed on the base plate 3101 by welding, and the column base connector 32 is fixed on the positioning plate 3103 by bolts or welding.

[0103] As a preferred, finely adjustable connection solution, a vertical threaded post 3104 can be welded onto the positioning plate 3103, while a first mounting hole 36 is opened at the bottom of the post base connector 32. During installation, the first mounting hole 36 of the post base connector 32 is inserted into the threaded post 3104, and then the nut 3105 is tightened on the threaded post 3104 to achieve a firm connection and initial leveling of the post base connector 32.

[0104] To enhance support for the upper chassis composite structure 55, a support plate 35 is welded onto the column base connector 32 (or between the inner core 33 and the column base connector 32). This support plate 35 can extend horizontally to support the upper frame or the third fixing plate 5102.

[0105] The chassis composite structure 55 is the core module of the entire system. It is manufactured and integrated in the factory, ensuring consistency and high quality. The chassis composite structure 55 includes a steel frame on which the chassis sleeve 51 is fixed.

[0106] The frame is specifically constructed as follows: The frame is composed of the main load-bearing component, the first type of steel 52. The first type of steel 52 can be C-shaped steel or rectangular tubing. When C-shaped steel is used, in order to enhance its connection strength, a connecting plate 58 can be welded to the bent part of the C-shaped steel (i.e., at the groove 8304).

[0107] The first type of steel 52 and the chassis sleeve 51 are spliced ​​together to form a grid-like stable structure. Between the two parallel first type of steel 52, a second type of steel 53, which serves as a secondary beam, can be fixedly connected. The second type of steel 53 can be made of C-shaped steel or rectangular tube to enhance the overall rigidity.

[0108] Within the same frame, the chassis sleeve 51 employs two methods: one where the chassis sleeve 51 has a through hole 5101 extending vertically, and another where a third fixing plate 5102 is welded to both ends of the through hole 5101. When the column base connector 32 corresponds to the structural column 2, the inner core 33 of the column base connector 32 is inserted into the through hole 5101, and the inner core 33 and the chassis sleeve 51 are fixed together with bolts. When the column base connector 32 corresponds to the door, the column base connector 32 has a connecting part 34, which supports the third fixing plate 5102, and the third fixing plate 5102 and the connecting part 34 are fixed together with bolts. Together, these constitute the mutually cooperating positioning structure of this application.

[0109] To further enhance structural strength, several reinforcing components are incorporated: a first reinforcing member 54, made of angle steel, is fixed between the second steel section 53 and the first steel section 52. The first reinforcing member 54 and the first steel section 52 are welded together, and the first reinforcing member 54 and the second steel section 53 are secured with bolts. A second reinforcing member 55 is fixed between two adjacent first steel sections 52, and is also secured to the first steel section 52 with bolts. A splicing member 56 is fixed between the first steel section 52 and the chassis sleeve 51, and is secured to the first steel section 52 with bolts, ensuring a secure connection.

[0110] The first type of steel 52, the second type of steel 53, and various reinforcing components together form a through cavity. The lower part of this cavity is sealed by a frame base plate 5704, preferably galvanized color steel sheet 409, which serves a sealing, moisture-proof, and decorative function. The upper part of the cavity is sealed by a structural plate, consisting of an interlocking base layer 5702 and a decorative surface layer 5703. This plate is a load-bearing structure. Insulation cotton 5701 can be filled into the cavity to achieve the thermal insulation function of the ground system, integrating structure, insulation, and sealing.

[0111] The chassis composite structure 55 requires overall hoisting at the construction site. Therefore, a steel pipe 5201 is welded into the first steel section 52. The first steel section 52 has a circular hole, and the steel pipe 5201 has a hoisting hole 5202. The hoisting hole 5202 is located below the circular hole and serves as a hoisting point for the chassis composite structure 55. Its inner wall is threaded, and threaded parts on the hoisting equipment pass through the circular hole and are threaded into the hoisting hole 5202, enabling the hoisting of the chassis composite structure 55. The steel pipe 5201 is hidden within the first steel section 52, resulting in a concealed hoisting point design that does not affect the subsequent installation operation of the chassis composite structure 55.

[0112] In one of the chassis composite structures 55, the second steel 53 is shortened and connected to the first steel 52, so that a reserved hole is formed in the chassis composite structure 55. A steel component 59 is then installed in the reserved hole and welded to the first steel 52 to form a bathroom chassis, which is used for bathroom installation later.

[0113] It reduces on-site welding, enables fully dry operation, increases installation speed, reduces reliance on manual labor, and eliminates welding pollution and safety hazards, meeting the green and environmentally friendly requirements of industrialized construction.

[0114] like Figures 18 to 26 As shown, the composite exterior wall panel 8 is connected to the node frame structure and is located between the roof module 7 and the integrated floor system.

[0115] The composite exterior wall panel 8 includes an interior decorative panel 81, an exterior decorative panel 88, pipes 811, a junction box 810, and a through-beam 812. An interior baseboard 82, a wall structure frame 83, an OSB board 85 (oriented strand board), and an extruded polystyrene insulation board 87 are sequentially connected between the interior decorative panel 81 and the exterior decorative panel 88. The pipes 811, junction box 810, through-beam 812, interior decorative panel 81, interior baseboard 82, wall structure frame 83, OSB board 85, extruded polystyrene insulation board 87, and exterior decorative panel 88 are combined to form the exterior wall panel 8. This allows for modular assembly and integration of the exterior wall panel 8 in the factory, facilitating rapid on-site installation and avoiding on-site welding. It integrates load-bearing, thermal insulation, sound insulation, waterproofing, pipework, and decorative functions, and is suitable for rapid industrial installation (production assembly), fully realizing the integration of the cavity and pipework. The through-beam 812 has pipe perforations for easy pipe laying.

[0116] The composite exterior wall panel 8 adopts a frame-type design, which can further improve transportation convenience and reduce logistics costs. Specifically, the wall structure frame 83 is prefabricated in the factory into frame units that conform to the height of standard shipping containers, facilitating stacking and transportation. The frame height can be standardized according to common container specifications, and its length can be flexibly adjusted according to the building facade division, taking into account both transportation economy and facade design freedom.

[0117] Interior decorative panels 81 and exterior decorative panels 88 can be assembled with the frame at the factory to form complete wall panel modules for overall transportation, or the frame and panels can be transported separately and installed on-site. The latter method is suitable for long-distance transportation or structures with complex facade designs, effectively avoiding damage during transportation and reducing the amount of transport capacity required.

[0118] The exterior wall panel 8 also includes a breathable paper 86, which is connected between the OSB board 85 and the extruded polystyrene insulation board 87. The breathable paper 86 can improve the waterproof and breathable function of the exterior wall panel 8 and effectively prevent condensation and structural corrosion.

[0119] The exterior wall panel 8 also includes a fireproof and soundproof panel 84 and thermal insulation cotton 5701. The fireproof and soundproof panel 84 and thermal insulation cotton 5701 are embedded in the wall structure frame 83 to improve the fireproof, soundproof and thermal insulation effect of the exterior wall panel 8. The thermal insulation cotton 5701 is located on both sides of the fireproof and soundproof panel 84.

[0120] The wall structure frame 83 includes a vertical frame 8301, a first ground joist 8302, and a second ground joist 8303. The first ground joist 8302 and the second ground joist 8303 are arranged parallel to each other. Several vertical frames 8301 are distributed between the first ground joist 8302 and the second ground joist 8303. Fireproof and soundproof board 84 and thermal insulation cotton 5701 are connected to the vertical frames 8301, the first ground joist 8302, and the second ground joist 8303.

[0121] The vertical frame 8301 is distributed between the first ground keel 8302 and the second ground keel 8303. A reinforcing block 8307 connects the vertical frame 8301 and the first ground keel 8302. The reinforcing block 8307 is provided with a hidden suspension point 8308. The first ground keel 8302 is provided with a through hole 8306 near the hidden suspension point 8308.

[0122] The design of the vertical frame 8301, the first ground keel 8302, and the second ground keel 8303 improves the installation stability of the fireproof and soundproof board 84 and the thermal insulation cotton 5701, enabling modular installation, improving construction efficiency, and the concealed suspension points 8308 can meet the requirements for overall hoisting of the exterior wall panel 8. The wall structure frame 83 ensures high strength and rigidity, and the fireproof and soundproof board 84 and thermal insulation cotton 5701 are embedded inside using a special-shaped steel frame structure, giving the exterior wall panel 8 good thermal insulation and sound insulation performance.

[0123] The vertical frame 8301 has slots 8304 at both the top and bottom, which facilitates the overall push-in installation of the exterior wall, avoids collision with the nuts at the top and bottom of the frame column during wall installation, and makes it easy to adjust the bolts.

[0124] The vertical frame 8301, the first ground keel 8302, and the second ground keel 8303 are equipped with an X-shaped support frame 8305 on the side closest to the outside, which can further improve the overall strength of the wall structure frame 83.

[0125] The exterior wall panels are assembled in the factory, and the water and electricity pipes and junction boxes are also installed in the factory.

[0126] When the exterior wall panel 8 is connected to the structural column 2, the two sides of the exterior wall panel 8 (with pre-reserved openings at the factory) are connected to the structural column 2 through connecting ear plates 9, which improves the stability and reliability of the connection between the exterior wall panel 8 and the structural column 2.

[0127] The connecting lug 9 has an X-shaped or T-shaped structure. The connecting lug 9 can be welded to the structural column 2 in the factory and quickly connected with bolts, facilitating rapid on-site installation and fixing, and avoiding on-site welding work.

[0128] When the connecting ear plate 9 adopts an X-shaped structure, it includes a first fixing plate 901 and a second fixing plate 902. The first fixing plate 901 is provided with a second mounting hole 903. The two adjacent first fixing plates 901, the two adjacent second fixing plates 902, and the two adjacent first fixing plates 901 and second fixing plates 902 are all perpendicularly connected to each other. This not only enables the fixed installation between the exterior wall panel 8 and the structural column 2, but also connects two adjacent exterior wall panels 8, improving the overall connection stability. The length of the first fixing plate 901 is greater than the length of the second fixing plate 902.

[0129] When the connecting ear plate 9 adopts a T-shaped structure, it includes a first fixing plate 901 and a second fixing plate 902. The second fixing plate 902 is vertically fixed to one side center line of the first fixing plate 901. The first fixing plate 901 is provided with two sets of second mounting holes 903, and the two sets of mounting holes are located on both sides of the second fixing plate 902.

[0130] Both ends of the indoor baseboard 82 are provided with opening grooves 8201 to avoid the connecting ear plate 9. The extruded insulation board 87 is vertically divided, and a keel 89 is provided between two adjacent extruded insulation boards 87. The keel 89 connects the OSB board 85 and the exterior decorative panel 88 respectively, improving the stability and reliability of the installation of the exterior decorative panel 88.

[0131] When installing exterior wall decorative panels on site, sealing strips can be used to fill the gaps at the bottom and top of the exterior wall panels. Self-adhesive expansion sealing strips can be used for these sealing strips.

[0132] Through the above structural design, not only can the node frame structure, roof module 7, integrated ground system and composite exterior wall panel 8 be processed in the factory, improving processing quality, precision and fewer defects, but also each module has pre-set lifting points in the factory, facilitating on-site hoisting. At the same time, by using high-strength, adjustable mechanical connection nodes and component connection methods with plug-in structural bolts, rapid positioning and fixing between modules and between modules and the main structure can be achieved. On-site, only hoisting and connection are required, thereby reducing the impact of weather and human factors and significantly shortening on-site operation time.

[0133] The installation process of this invention is as follows:

[0134] 1. On-site construction of column base 3: Concrete foundation 31 is poured on-site according to the design position, and column base connector 32 is precisely installed and leveled by pre-embedded steel bars 3102, base plate 3101, positioning plate 3103 and nuts 3105 and other components.

[0135] 2. Factory-prefabricated chassis composite structure 55: The entire chassis composite structure 55 is manufactured in the factory, including installing the frame, installing the chassis sleeve 51, laying the frame base plate 5704, filling the insulation cotton 5701, sealing the plate, and reserving the lifting points for the frame.

[0136] 3. Transport the prefabricated chassis composite structure 55 to the site and lift it using hoisting equipment. Insert it into the inner core 33 of the column base 3 through the through hole 5101 on the chassis sleeve 51. At the same time, the connecting part 34 on another chassis sleeve 51 supports the third fixing plate 5102 in the through hole 5101. At this time, the positioning structure automatically completes precise alignment, and the chassis composite structure 55 is supported by the support plate 35.

[0137] 4. Final tightening: Use bolts to pass through the chassis sleeve 51 and the inner core 33 and fix them. At the same time, use bolts to fix the connecting part 34 and the third fixing plate 5102. The support plate 35 can also be further fixed to the third fixing plate 5102 with bolts.

[0138] 5. In the factory, the first set of plug-in 403 and the second plug rod 405 are pre-welded to the upper and lower ends of the roof beam 4. The structural column 2 is vertically installed above the chassis sleeve 51, so that the bottom end of the structural column 2 is inserted into the inner core 33. The chassis sleeve 51 and the structural column 2 are fixedly connected to the inner core 33 by bolts.

[0139] 6. Insert the second insert rod 405 at the lower end of the roof beam 4 into the top of the structural column 2 and fix it in place using the second fastener 201.

[0140] 7. Insert the roof triangular truss 1 onto the first set of plug-in 403 at the upper end of the roof beam 4 in sequence, and fix it with the first fastener 404 to achieve rapid installation of the node frame structure.

[0141] 8. Install the roof upper chord support structure 6 between the roof triangular trusses 1, so that the top surface of the roof upper chord support structure 6 is flush with the top surface of the roof triangular trusses 1, and then lay the roof modules 7 on each roof upper chord support structure 6 to complete the overall assembly of the building system.

[0142] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to achieve substantially the same technical effect are all covered within the protection scope of the present invention.
