Description

Technical Field

[0001] This invention relates to the field of modular building technology, and specifically to an outdoor terrace structure and assembly method based on modular housing. Background Technology

[0002] Modular buildings are characterized by standardized prefabrication, rapid assembly, and recyclability. To enhance living quality, outdoor terraces are often added to the top of the modular units. The terrace structure must not only allow for rapid assembly but also possess reliable drainage performance and align with the core principles of modular building: disassembly and recyclability.

[0003] Existing modular building terraces typically use welded or bolted steel frames as the supporting skeleton, followed by waterproofing, drainage, and surface layers. For example, patent CN222333129U discloses a modular building integrated organized drainage device, which uses galvanized rectangular tube main beams and secondary beams welded to the top of a container as supports, and galvanized steel plates welded to the main beams to form drainage channels, thus achieving terrace drainage. Patent CN222500893U also discloses a similar solution, using galvanized rectangular tubes welded to the top of the container and support seats to form terrace support, with drainage channels installed on the support seats.

[0004] While the above solution can achieve the basic functions, it has the following technical defects: The supporting frame and drainage components are fixed to the top of the box by welding, which means that the terrace structure cannot be separated from the box module after the building's life cycle ends. The metal parts need to be disassembled by cutting and other methods, making it difficult to achieve high-value recycling and reuse, which is not conducive to the non-destructive disassembly and secondary recycling of modular buildings.

[0005] Most existing conventional terrace structures do not have dedicated concealed integrated lifting points. During construction, lifting lugs must be temporarily welded onto the box body. After hoisting, cutting the lifting lugs damages the anti-corrosion coating on the box surface, leaving weld scars and reducing the reuse value of the box module. Although there are related designs for concealed lifting points in other technical fields, such as the concealed telescopic lifting device disclosed in patent CN216105571U, it uses a manual pulling of the operating rod to expose the lifting point, and requires manual pushing back after hoisting. In the scenario of batch hoisting of modular buildings, such solutions require workers to operate manually at height, affecting assembly efficiency, and cannot achieve automatic locking and resetting of the lifting rings. Summary of the Invention

[0006] This invention proposes an outdoor terrace structure and assembly method based on modular housing to solve the problem that irreversible connections in existing modular terrace structures lead to the inability to disassemble without damage and to cause damage to the main structure during hoisting.

The terrace structure also includes a gutter for collecting rainwater. The anchoring system includes multiple anchoring components arranged in a grid on the structural base layer, and each anchoring component has a snap-fit ​​part at the top. The support system includes a prefabricated support frame, which comprises multiple longitudinal main support pipes running parallel to each other on the top plate and multiple transverse secondary support pipes running left and right. The support frame integrates a modular, prefabricated, fully covered drainage system for rainwater drainage, which is connected to the gutters. The drainage system includes drainage channels laid between adjacent longitudinal main support pipes and running in the same direction as the longitudinal main support pipes. The drainage channels are connected by bent connecting cover plates. The bent connecting cover plates are fixed to the longitudinal main support pipes via connecting clips that are fixed to the bottom of the longitudinal main support pipes and correspond one-to-one with the anchoring components. The longitudinal main support pipes are engaged with the anchoring components via the connecting clips. The enclosure structure integrates a hidden lifting point mechanism, which has an extended state and a retracted state. In the extended state, it can be retracted and returned to its original position by external force.

[0008] As a further improvement of the present invention, the anchoring assembly includes an anchoring seat located at the lower part and installed on the structural base layer, and a connecting assembly located at the upper part for connection with the support frame; the anchoring seat includes a lead screw and an expansion tube slidably connected to the lead screw; the bottom of the lead screw is an enlarged cone head, and the top is provided with a threaded end; the bottom of the expansion tube is provided with an opening; the connecting assembly includes a rotating sleeve and a screw, the inner wall of the rotating sleeve is provided with threads, and it is threadedly engaged with the screw; the rotating sleeve is threadedly connected to the threaded end of the lead screw through an inner nut fixed at its bottom; the locking part includes an anti-lifting baffle and a supporting nut arranged sequentially from bottom to top, the outer diameter of the supporting nut being smaller than the outer diameter of the anti-lifting baffle; the anti-lifting baffle and the supporting nut are relatively fixed in position on the screw; a locking groove is formed at the bottom of the connecting clamp, the width of the opening at the bottom of the locking groove is larger than the outer diameter of the supporting nut, but smaller than the outer diameter of the anti-lifting baffle; the distance between the top surface of the supporting nut and the bottom surface of the anti-lifting baffle is equal to the effective height inside the connecting clamp.

[0009] As a further improvement of the present invention, a connecting core tube corresponding to the transverse support secondary tube is welded to the side wall of the longitudinal support main tube; the bottom end of the transverse support secondary tube is provided with an opening, and the connecting core tube is sleeved through the opening; the transverse support secondary tube is provided with a through hole, and the corresponding side wall of the connecting core tube is provided with a waist hole; the transverse support secondary tube and the connecting core tube are connected by bolts.

[0010] As a further improvement of the present invention, the guide channel is a groove with an open top, and the top of the guide channel side plate is bent towards the center of the guide channel to form a folded edge; the bent connecting cover plate is fixed to the bottom of the longitudinal support main pipe; the side plates of adjacent guide channels and the corresponding side edges of the bent connecting cover plate are fixedly connected by riveting; both the guide channel and the bent connecting cover plate are formed by bending stainless steel plates, and a receiving slot is provided on the side wall of the gutter, and the ends of the guide channel and the bent connecting cover plate extend outward to be inserted into the receiving slot, and a gutter cover plate is provided on the top of the gutter.

[0011] As a further improvement of the present invention, the connecting clip is fixed to the bottom of the longitudinal support main tube by screws; the bottom of the connecting clip is provided with a snap-fit ​​connector for engaging with the bottom surface of the anti-pinch baffle to constrain the connecting clip, and the lower end of the snap-fit ​​connector is an inwardly bent edge; the bent connecting cover plate is provided with a downward protrusion, and the top of the connecting clip is provided with a groove that engages with the protrusion.

[0012] As a further improvement of the present invention, the enclosure structure includes columns fixed to the edge of the top plate of the box body, and crossbeams are fixedly installed between the columns. The enclosure structure also includes a hoisting module for assisting hoisting, and the hidden hoisting point mechanism includes a hoisting ring assembly that is telescopically arranged in the hoisting module.

[0013] As a further improvement of the present invention, a sealing plate and a limiting plate located below the sealing plate are fixed on the hoisting module. The hoisting ring assembly includes a U-shaped rod, on which a counterweight is fixed. The counterweight is disposed in the accommodating cavity between the sealing plate and the limiting plate. A through hole for the U-shaped rod to pass through is provided on the limiting plate. A strip hole for the U-shaped rod to pass through is provided on the sealing plate. A limiting block is fixed on the inner wall of the hoisting module. The limiting block is perpendicular to the long axis of the strip hole. The limiting block includes two blocks, which are fixed on both sides of the strip hole respectively. They are used to bear the weight during hoisting and also to limit the extreme position of the counterweight's rise.

[0014] As a further improvement of the present invention, the counterweight is a spindle-shaped structure with a central outward protrusion, including a horizontally arranged upper base and a lower base.

[0016] This invention also discloses an assembly method for an outdoor terrace structure based on modular housing, comprising the following steps: S1. Assembly stage in the workshop: S101. The enclosure structure with integrated concealed suspension mechanism is fixedly installed on the edge of the top plate of the box module; S102. On the structural base layer at the top of the box module, multiple anchoring components are installed in a grid arrangement; each anchoring component is adjusted to set the installation slope of the support system; the prefabricated support frame is connected and fixed to the anchoring components, and a full-coverage flow guiding system is integrated and installed on the support frame; S103. Connect the end of the flow guiding system to the gutter; S104. Install the floor layer on the support frame and install the corresponding trench cover on the gutter; S2. On-site hoisting and assembly stage: S201. Operate the concealed lifting point mechanism to change it from a retracted and locked state to an extended and locked working state; S202. The assembled box module with the outdoor terrace structure is hoisted into place using hoisting equipment, and then the hoisting is released to put the box module into place. During the process, the hidden hoisting mechanism is in the extended state. S203. After hoisting is completed, the hidden hoisting point mechanism is pressed by external force to return it to the retracted and locked state; when other modules are being stacked and hoisted, the self-weight of the modules or components that are being stacked and assembled above is used to achieve linkage reset during the assembly process.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The terrace structure described in this invention uses a grid-arranged, adjustable-height anchoring assembly to fix a prefabricated support frame with an integrated full-coverage drainage system to the top of the box-like structure. The anchoring, support, drainage, and enclosure components throughout the entire structural system are all connected mechanically using bolts, snap-fit ​​connections, rivets, and plug-in joints. This makes the terrace structure an independent functional module that can be prefabricated in the factory, hoisted on-site as a whole, and disassembled without damage. After the building's lifespan ends, all components can be reverse-engineered, truly achieving resource recycling.

[0018] 2. The terrace structure described in this invention integrates a fully covered drainage channel system beneath the floor layer, which can instantly collect seepage and runoff and quickly guide them into the gutters via a preset slope. The drainage channel and the gutters are connected by a plug-in reverse edge, ensuring reliable sealing and convenient installation and disassembly. The bottom of the gutters is designed with a bidirectional drainage slope, higher in the middle and lower on both sides, and is equipped with a dirt-blocking net, effectively accelerating drainage, preventing water accumulation and blockage, forming a highly efficient, low-maintenance three-dimensional drainage system.

[0019] 3. The terrace structure described in this invention integrates a telescopic hidden lifting point mechanism within the enclosure structure. When extended, this mechanism can be retracted and returned to its original position by external force. During hoisting, the lifting ring is unlocked to extend and lock; after completion, the lifting ring is pressed back into the hoisting module and locked. This completely replaces the temporary lifting lug process that requires welding, cutting, and repair, fundamentally eliminating permanent damage to the box structure and anti-corrosion layer during hoisting, and protecting the integrity and reuse value of the module.

[0020] 4. The terrace structure described in this invention, through the use of a grid-arranged adjustable-height anchoring assembly (lead screw, rotating sleeve, threaded rod), allows for precise adjustment of the height of each support point during installation, thereby easily and accurately forming the required overall drainage slope. Simultaneously, the upper part of the anchoring assembly is equipped with a support nut and an anti-tipping baffle, which cooperate with the connecting clips fixed to the bottom of the longitudinal support main pipe; the connecting core tube fixed on the side wall of the longitudinal support main pipe cooperates with the transverse support secondary pipe with a groove at the bottom, enabling rapid assembly of the support frame and significantly improving assembly efficiency. Furthermore, the guide channel and the bent connecting cover plate are flexibly connected by riveting, providing space for the expansion and contraction of metal components due to temperature changes, effectively suppressing the risk of structural deformation, loosening, or tearing of the waterproof layer.

[0021] 5. The terrace structure described in this invention, by setting up a floor layer and a drainage system, and combining it with a flexible waterproof layer set on the structural base layer, unifies the runoff generated by the floor layer, the water flow that seeps into the drainage channel through the floor layer, and the water flow formed on the flexible waterproof layer into the gutter and discharged through the downpipe, significantly improving drainage efficiency.

[0024] The technical solutions and effects of the present invention will be described in detail below with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] like Figure 1As shown, an embodiment of an outdoor terrace structure based on a modular house is provided, wherein the terrace structure is installed on the top plate 101 of the box module 100. A rigid insulation layer 102 and a flexible waterproof layer 103 are laid on the top plate 101 from bottom to top, together forming the structural base layer for installing the terrace structure. To provide a solid foundation for the connection of the superstructure, the top plate 101 of the box module 100 is preferably a fiber-reinforced autoclaved aerated concrete (AAC) panel.

[0026] Combination Figures 2 to 7 As shown, the outdoor terrace structure based on modular housing includes an anchoring system connected to the structural base layer. A support system is connected to the anchoring system, and the support system includes a support frame 300 and a split-assembly, fully covered drainage system 400 integrated on the support frame 300. A floor layer 200 is installed on the support frame 300. The terrace structure also includes an enclosure structure 700 fixedly installed along the edge of the roof slab 101, and the enclosure structure 700 integrates a retractable, concealed suspension mechanism. The terrace structure also includes a gutter 600 installed on one side of the slope bottom of the support frame 300, and a socket for communicating with the drainage system 400 is provided on the side wall of the gutter 600.

[0027] The anchoring system includes multiple anchoring components 500 arranged in a grid on the structural base layer. For example... Figure 8 and Figure 9 As shown, the anchoring assembly 500 includes an anchoring seat 510 located at the lower part and installed on the structural base layer, and a connecting assembly 520 located at the upper part for connection with the support frame 300. The anchoring seat 510 includes a lead screw 512 and an expansion tube 511 slidably connected to the lead screw 512. The lead screw 512 has an enlarged cone at the bottom, a smooth rod in the middle that slidably engages with the expansion tube 511, and a threaded end at the top. The expansion tube 511 has an opening at the bottom. The connecting assembly 520 includes a rotating sleeve 521 and a screw 522. The inner wall of the rotating sleeve 521 is threaded and threadedly engages with the screw 522. The rotating sleeve 521 is connected to the threaded end of the lead screw 512 by an inner nut fixed at its bottom. The top of the screw 522 has an anti-tipping baffle 523 and a support nut 524 arranged sequentially from bottom to top. The outer diameter of the support nut 524 is smaller than the outer diameter of the anti-tipping baffle 523. The anti-pinch baffle 523 and the supporting nut 524 are fixed in position on the screw 522. Preferably, the anti-pinch baffle 523 and the supporting nut 524 are integrally formed with the screw 522.

[0028] Combination Figures 1 to 5As shown, the support frame 300 includes multiple longitudinal support main pipes 310 arranged parallel to the top plate 101 of the box body and multiple transverse support secondary pipes 330 arranged horizontally. Both the longitudinal support main pipes 310 and the transverse support secondary pipes 330 are square steel pipes. A connecting core pipe 320 corresponding to the transverse support secondary pipe 330 is welded to the side wall of the longitudinal support main pipe 310. The transverse support secondary pipe 330 is fitted onto the connecting core pipe 320 through an opening at its bottom. To achieve a fixed connection, a through hole is provided on the transverse support secondary pipe 330, and a waist hole for adjusting installation errors is provided on the corresponding side wall of the connecting core pipe 320. Bolts pass through the through hole and the waist hole to lock the two together.

[0029] Combination Figures 2 to 7 As shown, the flow guiding system 400 includes a flow guiding groove 410, which is laid between two adjacent longitudinal support main pipes 310 and runs in the same direction as the longitudinal support main pipes 310. The flow guiding groove 410 is a groove with an open top, and the top of the side plate of the flow guiding groove 410 is bent towards the center of the flow guiding groove 410 to form a folded edge. The bottom of the longitudinal support main pipe 310 is connected to a bent connecting cover plate 420 for connecting with the flow guiding groove 410. The side plates of adjacent flow guiding grooves 410 and the corresponding side edges of the bent connecting cover plate 420 are fixedly connected by riveting. Both the flow guiding groove 410 and the bent connecting cover plate 420 are formed by bending stainless steel plates, and in order to facilitate insertion and fixation with the socket on the side wall of the gutter 600, their ends are bent outward to form an edge 430.

[0030] The bent connecting cover plate 420 is fixedly connected to the longitudinal support main pipe 310 via connecting clips 340. Each connecting clip 340 corresponds to one of the anchoring components 500, meaning the bent connecting cover plate 420 is sandwiched between the connecting clips 340 and the longitudinal support main pipe 310. The bottom of the connecting clip 340 has a groove, the width of which is greater than the outer diameter of the supporting nut 524 but smaller than the outer diameter of the anti-pinch baffle 523. Simultaneously, the distance between the top surface of the supporting nut 524 and the bottom surface of the anti-pinch baffle 523 is equal to the effective height inside the connecting clip 340. When the connecting clip 340 is engaged with the connecting assembly 520, the supporting nut 524 enters the connecting clip 340 from bottom to top and contacts the inner top surface of the clip to provide support. Simultaneously, the anti-pinch baffle 523 pushes open the elastic fold at the lower end of the connecting clip 340 and enters the clip's interior. The elastic fold then returns to its original shape, its inner side abutting against the bottom surface of the anti-pinch baffle 523, thus simultaneously providing vertical support and upward anti-pinch constraint for the support frame 300. The connecting clip 340 is fixed to the bottom of the longitudinal support main tube 310 with screws. The bottom of the connecting clip 340 has a snap-fit ​​connector for engaging with the bottom surface of the anti-pinch baffle 523 to constrain the connecting clip 340; the lower end of the snap-fit ​​connector is an inwardly bent fold. For easy positioning during installation, the bent connecting cover plate 420 has a downward protrusion, and the top of the connecting clip 340 has a groove that mates with the protrusion.

[0031] like Figure 4 As shown, the gutter 600 includes a U-shaped channel 610, which is made of stainless steel. A socket is formed on the side wall of the U-shaped channel 610 where it intersects with the guide channel 410. The inner bottom wall of the U-shaped channel 610 slopes to the left and right sides, with a drain outlet at the lowest elevation. A downpipe 640 connects to the downpipe, facilitating the flow of rainwater from the guide channel 410 into the stainless steel gutter 600, which then flows into the downpipe along the slope of the gutter 600 and is finally discharged through the downpipe. A screen 630 is installed on the downpipe to prevent silt from entering and clogging the downpipe 640. The top of the U-shaped channel 610 has a groove flange 611, on which a gutter cover 620 is supported.

[0032] The specific material of the floor layer 200 can be selected according to the decoration requirements, such as anti-slip and weather-resistant paving materials, like anti-slip floor tiles or anti-corrosion wood paving.

[0033] Combination Figure 8 As shown, in one embodiment of the present invention, the enclosure structure 700 includes columns 710 fixed to the edge of the top plate 101, and crossbeams 720 are fixedly installed between the columns 710. While fulfilling its support and protection functions, the style of the enclosure structure 700 can be varied according to the building facade design.

[0034] After calculating the center of gravity of the housing module 100 based on its internal functional layout, lifting points are symmetrically arranged along the edge of the housing. Lifting modules 730 for auxiliary lifting are set at the predetermined lifting points. The lifting module 730 is equipped with a lifting ring assembly that can extend out of the top surface of the lifting module 730.

[0035] As an embodiment of the present invention, combined with Figures 11 to 13 As shown, the hoisting module 730 is fixed with a sealing plate 735 and a limiting plate 731 located below the sealing plate 735. The lifting ring assembly includes a U-shaped rod 734, on which a counterweight 733 is fixed. The counterweight 733 is disposed in the accommodating cavity between the sealing plate 735 and the limiting plate 731. The limiting plate 731 has a through hole for the U-shaped rod 734 to pass through. The sealing plate 735 has a strip-shaped hole for the U-shaped rod 734 to pass through. The inner wall of the hoisting module 730 is fixed with limiting blocks 736. The limiting blocks 736 are perpendicular to the long axis of the strip-shaped hole. The limiting blocks 736 include two blocks, which are fixed on both sides of the strip-shaped hole respectively, for bearing the weight during hoisting and for limiting the extreme position of the counterweight 733. The hammer 733 is a spindle-shaped structure that protrudes outward from the center. It includes a horizontally arranged upper base and a lower base. Between the upper base and the lower base is a protrusion formed by the intersection of two inclined surfaces. The first inclined surface at the lower part extends downward from the intersection line and gradually approaches the axis of the hammer 733. The second inclined surface at the upper part extends upward from the intersection line and gradually approaches the axis of the hammer 733.

[0036] Let H be the distance between the sealing plate 735 and the limiting plate 731, h1 be the distance between the top of the U-shaped rod 734 and the top of the counterweight 733, h2 be the distance between the top and bottom of the counterweight 733, h3 be the distance between the bottom of the counterweight 733 and the bottom of the U-shaped rod 734, h4 be the distance between the bottom of the locking tongue 738 and the bottom of the sealing plate 735, and h5 be the thickness of the limiting block 736. To ensure that the lifting ring assembly can fully retract into the receiving chamber and has sufficient travel within the receiving chamber, and will not be jammed by the sealing plate 735 and the limiting plate 731, the following conditions must be met: H is less than the sum of h2, h3 and h5, and h4 is greater than or equal to h1.

[0037] like Figures 11 to 13 As shown, a first spring 732 is sleeved on the rod body between the counterweight 733 and the limiting plate 731 on the U-shaped rod 734. The arc-shaped rod body at the top of the U-shaped rod 734 passes upward through a strip hole opened on the sealing plate 735. The sealing plate 735 has a strip hole for the top of the U-shaped rod 734 to pass through, but the counterweight 733 cannot pass through the strip hole. The side wall of the hoisting module 730 is provided with symmetrically arranged locking tongues 738. A stop block is provided on the outside of the locking tongue 738, and a second spring 737 is connected between the stop block and the side wall of the corresponding side hoisting module 730.

[0038] The following is an assembly process according to a specific embodiment of the present invention. The process mainly includes two stages: structural assembly in the workshop and hoisting on site: S1. Assembly steps in the workshop: S101. Assemble the enclosure: Holes are drilled in the limiting plate 731. Two first springs 732 are aligned with the pre-drilled holes and fixed to the limiting plate 731. The limiting plate 731 with the first springs 732 fixed to it is then horizontally welded inside the lifting module 730. A U-shaped rod 734 is passed through the counterweight 733 and welded in place, with both ends of the rod passing downwards through the springs and the limiting plate 731 respectively. The upper end of the first spring 732 is welded to the bottom of the counterweight 733. At this point, the counterweight 733 remains extended under the action of the first spring 732. The stop block is then welded to the locking tongue 738. A second spring 737 is fitted onto the locking tongue 738, and the locking tongue 738 is inserted through and into the side wall of the lifting module 730. The two ends of the second spring 737 are welded to the stop block and the corresponding side wall of the lifting module 730, respectively. Finally, the limiting block 736 is welded to the inner wall of the lifting module 730, ensuring that the limiting block 736 is perpendicular to the long axis of the strip hole. Next, align the strip hole on the sealing plate 735 with the top of the U-shaped rod 734, so that the U-shaped rod 734 passes through the strip hole. At this time, the limiting block 736 contacts the top surface of the counterweight 733. Then, press the sealing plate 735 down to push the counterweight 733 downward to compress the first spring 732 until the sealing plate 735 contacts the top of the lifting module 730. Then, weld the sealing plate 735 to the top of the lifting module 730 firmly. The assembly of the lifting module 730 is completed. Next, fix the column 710, the crossbeam 720 and the lifting module 730 to the corresponding positions of the box module 100, and install the enclosure.

[0039] S102. Assemble the support system: The span is determined based on the bearing capacity of the supporting system pipes, and a positioning baseline for the longitudinal support main pipe 310 is set on the base layer. Along the positioning baseline of the longitudinal support main pipe 310, holes are drilled in the structural base layer at 0.6-meter intervals. Anchor seats 510 are installed, and after tightening the rotating sleeve 521 and the threaded rod 512, the sleeve 521 is rotated further to compress the expansion tube 511, causing its bottom to open and tightly integrate with the structural base layer, ensuring a stable connection. The top elevation of the screw rod 522 is determined one by one according to the design slope, and then the screw rod 522 is screwed into the rotating sleeve 521 sequentially. Guide channels 410 are placed on both sides of the same positioning baseline along its direction. According to the installation spacing of the transverse support pipes, the connecting core pipe 320 is pre-welded to the side wall of the longitudinal support pipe. Then, the bent connecting cover plate 420 and the connecting clip 340 are fixed to the bottom wall of the longitudinal support main pipe 310 with self-tapping screws. The bent connecting cover plate 420 is installed between the connecting clip 340 and the longitudinal support main pipe 310. The connecting clip 340 corresponds one-to-one with the anchoring component 500, completing the assembly of the longitudinal support pipe. The side of the longitudinal support main pipe with the bent cover plate and connecting clip 340 facing downwards is then positioned, keeping the positioning groove in the center of the connecting clip 340 aligned with the support nut 524. The support nut 524 passes through the connecting clip 340 and engages with the anti-pinch baffle 523, thereby achieving a stable connection between the anchoring system and the longitudinal support main pipe 310. Then, the bent connecting cover plate 420 is fixed to the side plate of the corresponding side guide groove 410 by riveting. The transverse support secondary pipe 330 is then snapped downwards onto the connecting core pipe 320 and fixed with bolts, completing the assembly of the support system.

[0040] S103. Install a drainage system: Install a gutter 600 near the inside of the enclosure at the lower end of the terrace slope, and pass the guide channel 410 through the slot of the gutter 600 side wall.

[0041] S104. Install floor layer 200 and trench cover 620.

[0042] Following the steps above, complete the assembly of the terrace structure and the box module 100.

[0043] S2. On-site hoisting and assembly process: S201. Pull the locking tongue 738 outward to disengage the bottom surface of the locking tongue 738 from the top surface of the counterweight 733, releasing the constraint of the locking tongue 738 on the counterweight 733. Under the restoring force of the first spring 732, the counterweight 733 moves upward, and the upper inclined surface of the counterweight 733 pushes the locking tongue 738 outward. After the widest part of the counterweight 733 passes the locking tongue 738, the lower inclined surface of the counterweight 733 contacts the arc surface of the locking tongue 738. Under the pull of the second spring 737, the locking tongue 738 retracts until the top surface of the counterweight 733 abuts against the limiting block 736, thereby stabilizing the U-shaped rod 734 in the extended state, preparing for hoisting.

[0044] S202. The assembled box module 100 with the outdoor terrace structure is hoisted into place using hoisting equipment, and then the hoisting is released. At this time, the U-shaped rod 734 is still in the extended state.

[0045] S203. After hoisting, the concealed lifting point mechanism is pressed by external force to return to its retracted and locked state. When other modules are being stacked and hoisted, the weight of the modules or components being stacked and assembled above presses down on the U-shaped rod 734, causing the counterweight 733 to move downwards. The inclined surface of the lower part of the counterweight 733 contacts the arc surface of the upper part of the locking tongue 738, pushing the locking tongue 738 outwards and stretching the second spring 737. When the widest part of the counterweight 733 passes the bottom surface of the locking tongue 738, the second spring 737 deforms to its maximum state. Subsequently, the counterweight 733 continues to move downwards. Under the restoring force of the second spring 737, the end of the locking tongue 738 gradually retracts along the inclined surface of the upper part of the counterweight 733 until the upper bottom of the counterweight 733 coincides with the lower bottom of the locking tongue 738. The two opposing locking tongues 738 pass through the U-shaped rod 734 and abut against each other to form a stable constraint surface. Under the restoring force of the first spring 732, the counterweight 733 pushes upwards against the constraint surface, thereby achieving locking. The U-shaped rod 734 is concealed within the hoisting module 730, enabling linkage and reset during the assembly process without affecting subsequent surface decoration.

[0046] The assembled box module 100 with the terrace structure and other box modules 100 are hoisted into place and connected in sequence to complete the house construction.

[0047] The terrace structure described in this invention can be assembled with the standard box module 100 to form a box module 100 that fully covers the terrace or a box module 100 that partially covers it. Then, it can be combined with the standard box module 100 and the roof module as needed to meet the diverse needs of users.

[0048] It should be noted that, as will be apparent to those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics thereof. The scope of the present invention is defined by the claims rather than the foregoing description.
