Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a detachable support system and its construction method. Background Technology

[0002] Nuclear power projects are large in scale, have long cycles, and contain many heavy structural components. The plant structures are mostly thick beams and slabs, and the room layouts and dimensions are special. This directly leads to the need for traditional scaffolding support systems to use dense uprights or custom-made diagonal braces to meet the load-bearing requirements.

[0003] Against this backdrop, in structurally complex areas (such as floor slabs spanning multiple floors, rooms where equipment is introduced in advance, confined spaces, and staggered structures), traditional scaffolding support systems, namely full-span scaffolding or four-column ground-based support methods, have become the mainstream choice. However, these support methods have an "exclusivity" in occupying the space below: full-span scaffolding must distribute the load by setting up dense uprights, and the connecting components such as horizontal bars and base bars in the longitudinal and transverse directions intertwine to form a three-dimensional grid structure, occupying most of the space below.

[0004] The encroachment on most of the lower level space will directly hinder the early introduction of equipment, forcing subsequent installation procedures to be postponed. At the same time, parallel construction of other trades such as decoration work and pipeline laying will also be completely blocked, forcing each process to proceed sequentially, which will undoubtedly greatly extend the construction period. Summary of the Invention

[0005] One of the objectives of this invention is to address the problem that existing scaffolding support systems in nuclear power reactor construction, due to their "exclusive" occupation of lower-level space, hinder the early introduction of equipment, disrupt parallel construction by multiple trades, and thus affect construction efficiency.

[0006] The second objective of this invention is to provide a construction method for a detachable support system.

[0007] To achieve one of the above objectives, the present invention adopts the following technical solution: a detachable support system comprising an anchoring component and a support component, wherein the anchoring component, which is pre-embedded in the wall, is provided with a locking hole, the locking hole comprising a wide-diameter region and a narrow-diameter region.

[0008] The support component is provided with a mating part, the size of which is larger than the narrow diameter region and smaller than the wide diameter region. After the mating part passes through the wide diameter region, it can move to the narrow diameter region to form a mechanical lock.

[0009] The anchoring assembly and the support assembly are assembled and disassembled through the coordinated action of the locking hole and the mating part.

[0010] In the above technical solution, the operation of the detachable support system of this invention begins with the pre-embedding stage of the anchoring components. During wall construction, the anchoring components are pre-embedded in the wall to form a stable connection with the wall structure. At this time, the locking holes (including wide-diameter and narrow-diameter areas) on the anchoring components are exposed on the outside of the wall as the connection base. After the wall is formed and reaches a certain strength, the installation stage of the support components can begin.

[0011] During installation, the mating part of the support assembly must be aligned with the wide-diameter area of ​​the locking hole of the anchor assembly. Since the size of the mating part is smaller than the wide-diameter area, it can easily pass into the locking hole. Then, the mating part of the support assembly is moved from the wide-diameter area to the narrow-diameter area along the extension direction of the locking hole. Because the size of the mating part is larger than the narrow-diameter area, a tight mechanical engagement is formed between the mating part and the inner wall of the locking hole of the anchor assembly, restricting the axial and radial movement of the support assembly along the locking hole. This achieves a secure lock between the support assembly and the anchor assembly, enabling the support assembly to stably bear the load transmitted from above.

[0012] After the support system has fulfilled its supporting function (such as the floor slab being poured and reaching its design strength), the dismantling phase begins. Dismantling requires a reverse operation: the mating parts of the support components are moved from the narrow-diameter area back to the wide-diameter area. At this point, the mating parts are no longer restricted by the narrow-diameter area and can be easily removed from the wide-diameter area, achieving separation of the support components and anchoring components. After separation, the support components can be recycled for future use, while the anchoring components remain embedded in the wall, not affecting the integrity of the wall structure and reserving space for possible secondary use or other construction steps. The entire process requires no complex tools; assembly and dismantling are completed simply by moving the mating parts within the locking holes, making the operation convenient and efficient.

[0013] The beneficial effects of this invention are: Traditional support systems, due to their "exclusivity," occupy lower-level space, hindering the early introduction of equipment and disrupting parallel construction by multiple trades. This invention, however, achieves rapid assembly and disassembly through a mechanically locked, detachable connection between the anchoring and support components. The mating part of the support component inserts into the wide-diameter area of ​​the anchoring component, while the mating part is larger than the narrow-diameter area. After the mating part moves to the narrow-diameter area, a mechanical engagement and locking occurs. Thus, rapid assembly and disassembly can be completed simply by moving the mating part between the two areas. After the support system completes its support function, it does not occupy lower-level space, fundamentally eliminating the "exclusivity" of lower-level space occupation. This allows for the early introduction of equipment and supports simultaneous work by multiple trades, effectively shortening the construction cycle.

[0014] Furthermore, in this embodiment of the invention, the anchoring assembly includes a plate and an embedded part that are connected and fixed together, the embedded part being configured to be embedded in the wall to fix the anchoring assembly.

[0015] Furthermore, in this embodiment of the invention, the wide diameter region of the locking hole is a circular hole, the narrow diameter region is an elongated hole, and the elongated hole communicates with the circular hole.

[0016] Furthermore, in this embodiment of the invention, the support component is a rigid structure, the mating part is fixed to one end of the support component, the mating part has a connected rod and a radial protrusion, and the radial protrusion protrudes from the end of the rod.

[0017] Furthermore, in this embodiment of the invention, the anchoring assembly further includes a sealing unit, which is used to seal the locking hole when the anchoring assembly is pre-embedded, so as to prevent wall material from intruding.

[0018] Furthermore, in this embodiment of the invention, the detachable support system further includes a load-bearing adjustment component connected to the support component and configured to adjust the height to adapt to different elevation requirements, while bearing the upper load.

[0019] Furthermore, in this embodiment of the invention, the load-bearing adjustment assembly includes a steel pipe, a top support rod, a nut, and a support. The steel pipe is fixedly connected to the support assembly by a plug-in connection. The support is installed on the top support rod, and the top support rod is threadedly connected to the nut. The inner buckle of the nut directly locks and fixes the steel pipe. The nut is rotated to raise and lower the top support rod along the axial direction of the steel pipe to adjust the support height, so as to support the I-beam or engineered wood.

[0020] To achieve the second objective mentioned above, the present invention adopts the following technical solution: a construction method for a detachable support system, comprising the following steps: (1) Embed the pre-embedded parts of the anchoring component in the wall, and clean the locking holes of the anchoring component after the wall is formed.

[0021] (2) The mating part of the support component passes through the wide diameter area of ​​the locking hole and moves to the narrow diameter area to form a mechanical lock to fix the support component.

[0022] (3) Adjust the load-bearing adjustment component connected to the support component. By adjusting the height and verticality of the load-bearing adjustment component, the load-bearing surface of the load-bearing adjustment component is kept flat.

[0023] (4) Based on the floor slab type, lay templates or precast layers on the load-bearing surface of the load-bearing adjustment components and pour concrete.

[0024] (5) After the floor slab reaches the preset strength, lower the load-bearing adjustment component so that the load-bearing surface of the load-bearing adjustment component is separated from the floor slab. Move the mating part of the support component back to the wide diameter area to remove the support component and recycle it for reuse.

[0025] Furthermore, in this embodiment of the invention, in step (1), the locking hole is sealed by a sealing unit when the anchoring component is pre-embedded, and the sealing unit is removed after the wall is formed.

[0026] Furthermore, in this embodiment of the invention, in step (3), the load-bearing adjustment component adjusts the height of the support bearing surface on the top support rod by means of the threaded connection between the nut and the top support rod, and the flatness of the bearing surface is achieved by the synchronous adjustment of multiple sets of load-bearing adjustment components.

In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, construction methods and structures of well-known detachable support systems have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other. Example

[0035] It should be noted that the accompanying drawings are part of the content of the instruction manual. The structural shapes, connections, fits, and positional relationships that can be clearly seen in the accompanying drawings should all be understood as part of the content of the instruction manual.

[0036] A detachable support system, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes an anchoring component 10 and a support component 20. The anchoring component 10 can be made of steel and typically includes a plate and a steel bar embedded part 14. The plate is a rectangular or square metal plate, and the embedded part 14 is a steel bar or steel claw welded to the back end of the plate for fixing to the wall concrete. The steel bar embedded part 14 is used to be embedded in the wall for fixing.

[0037] like Figure 2As shown, the plate of the anchoring assembly 10 is provided with a locking hole that runs through the front and back. The locking hole includes a wide diameter region 11 and a narrow diameter region 12.

[0038] like Figure 4 As shown, the support component 20 can also be made of steel, and is mostly a triangular welded structure, which is made of horizontal and diagonal bars welded together, and has rigid load-bearing capacity.

[0039] The support component 20 can be a triangular rigid structure welded from angle steel. The mating part 21 welded to the back end of the triangular rigid structure has a size that matches the wide and narrow diameter regions 12 of the locking hole. That is, the size of the mating part 21 is larger than the narrow diameter region 12 and smaller than the wide diameter region 11. After the mating part 21 passes through the wide diameter region 11, it can move to the narrow diameter region 12 to form a mechanical lock.

[0040] The anchoring assembly 10 and the support assembly 20 are assembled and disassembled through the coordinated action of the locking hole and the mating part 21.

[0041] Detailed Implementation: The operation of the detachable support system begins with the pre-embedding stage of the anchoring component 10. During wall construction, the anchoring component 10 is pre-embedded in the wall to form a stable connection with the wall structure. At this time, the locking holes (including the wide-diameter region 11 and the narrow-diameter region 12) on the anchoring component 10 are exposed on the outside of the wall as the connection base. After the wall is formed and reaches a certain strength, the installation of the support component 20 can begin.

[0042] During installation, the mating part 21 of the support assembly 20 must be aligned with the wide-diameter region 11 of the locking hole of the anchor assembly 10. Since the size of the mating part 21 is smaller than that of the wide-diameter region 11, it can be smoothly inserted into the locking hole. Subsequently, the mating part 21 of the support assembly 20 is moved from the wide-diameter region 11 to the narrow-diameter region 12 along the extension direction of the locking hole. Since the size of the mating part 21 is larger than that of the narrow-diameter region 12, the mating part 21 forms a tight mechanical engagement with the inner wall of the locking hole of the anchor assembly 10, restricting the axial and radial movement of the support assembly 20 along the locking hole, thereby achieving a firm lock between the support assembly 20 and the anchor assembly 10, enabling the support assembly 20 to stably bear the load transmitted from above.

[0043] After the support system has completed its supporting function (such as the floor slab being poured and reaching its design strength), the dismantling process begins. Dismantling requires a reverse operation: the mating part 21 of the support component 20 is moved from the narrow-diameter area 12 back to the wide-diameter area 11. At this point, the mating part 21 is no longer restricted by the narrow-diameter area 12 and can be easily removed from the wide-diameter area 11, achieving separation of the support component 20 from the anchoring component 10. After separation, the support component 20 can be recycled for later use, while the anchoring component 10 remains embedded in the wall, without affecting the integrity of the wall structure, reserving space for possible secondary use or other construction steps. The entire process requires no complex tools; assembly and dismantling can be completed simply by moving the mating part 21 within the locking hole, making the operation convenient and efficient.

[0044] The advantage of this invention lies in the fact that traditional support systems, due to their "exclusivity," occupy lower-level space, hindering the early introduction of equipment and disrupting parallel construction by multiple trades. In contrast, this invention achieves rapid assembly and disassembly through a mechanically locked, detachable connection between the anchoring component 10 and the support component 20. The mating part 21 of the support component 20 inserts into the wide-diameter region 11 of the anchoring component 10, while the mating part 21 is larger than the narrow-diameter region 12. After the mating part 21 moves to the narrow-diameter region 12, a mechanical engagement lock is formed. Thus, rapid assembly and disassembly can be completed simply by moving the mating part 21 between the two regions. After the support system completes its support function, it does not need to occupy lower-level space, fundamentally eliminating the "exclusivity" of lower-level space occupation. This allows for the early introduction of equipment and supports simultaneous work by multiple trades, effectively shortening the construction cycle.

[0045] The most significant feature of this invention is its "fastener-free mechanical locking": rigid engagement is achieved by using size adaptation, which avoids the cumbersome connection methods of traditional support systems that rely on bolts, welding and other complex methods. Furthermore, the locking or unlocking state is switched by the movement of a purely mechanical structure. The operation only requires simple insertion and translation, which greatly simplifies the assembly and disassembly process.

[0046] Specifically, such as Figure 3 As shown, the anchoring assembly 10 also includes a sealing unit 13, which is used to seal the locking hole when the anchoring assembly 10 is pre-embedded to prevent wall material from intruding.

[0047] In practical applications, pre-embedded components with holes will inevitably fail during construction due to the intrusion of debris. Therefore, the design of such locking holes is easily rejected in conventional thinking, and its application has significant non-obviousness.

[0048] Specifically, during construction, especially in the pouring of thick walls in nuclear power projects, cement slurry, sand, and other debris are highly fluid and permeable. Traditionally, setting through-holes like locking holes in embedded components presents two critical problems: first, debris intrudes into the hole during pouring, solidifying and completely blocking the channel, preventing subsequent support components from being inserted or locked; second, even if cleaning is attempted, the hardened debris damages the precision of the hole's inner wall, affecting the stability of the mechanical locking and ultimately causing the connection structure to fail. Therefore, the industry typically avoids setting such functional holes in embedded components, opting instead for hole-free connection methods such as welding and embedded bolts. However, these methods either lack detachability or have extremely low assembly / disassembly efficiency, failing to meet the rapid turnover and space release requirements of nuclear power projects.

[0049] The design of the locking hole in the detachable support system of this invention challenges this traditional understanding: by equipping it with a sealing unit 13, the risk of debris intrusion is first isolated during the construction phase, and then the floating debris is cleaned after the wall is formed or reaches a certain strength, ensuring the integrity of the hole's function. This combination of "pre-set hole + sealing protection + post-cleaning" not only retains the core function of the locking hole to achieve rapid mechanical locking, but also solves the problem of blockage that is most likely to cause hole failure during construction, breaking the mindset that "pre-embedded holes will inevitably fail".

[0050] The "unexpected" aspect of this design lies in its recognition of the potential blockage risk of the locking holes during construction. However, it does not abandon the hole design due to this risk. Instead, through simple and effective sealing and cleaning steps, it transforms the traditionally perceived "risk point" into an "innovation point." This not only enables the rapid assembly and disassembly of the support component 20 and the anchoring component 10 (through the wide-diameter area 11 and locking through the narrow-diameter area 12), but also avoids the cumbersome operation and space occupation problems of traditional holeless connection methods (such as welding and bolts). Especially in the complex spaces of nuclear power engineering (spanning multiple floors and narrow areas), this design, which balances stability, disassembly, and construction feasibility, far exceeds the expectations of conventional support systems, fully demonstrating the non-obviousness and technological breakthrough of the locking hole setting.

[0051] Specifically, such as Figure 2 As shown, the wide diameter region 11 of the locking hole is a round hole, and the narrow diameter region 12 is an elongated hole, which is connected to the round hole.

[0052] Specifically, the wide-diameter region 11 (circular hole) of the locking hole provides an initial insertion channel for the mating part 21. Due to its circular design, the mating part 21 can be easily aligned and inserted from any angle. The narrow-diameter region 12 (elongated hole) communicates with the circular hole and extends in a straight line. After the support assembly 20 is inserted, it translates along the direction of the elongated hole, causing the radial protrusion of the mating part 21 to engage with the edge of the elongated hole. This structure ensures that the mating part 21 can only move along the direction of the elongated hole in the locked state (limited by the size of the protrusion), thus improving locking stability.

[0053] The wide-diameter region 11 can also be elliptical, with its major axis aligned with the extension direction of the narrow-diameter region 12. This design allows the mating part 21 (such as a radial protrusion) to enter through the major axis of the ellipse during insertion, while the minor axis of the ellipse remains larger than the narrow-diameter region 12, ensuring locking reliability. For example, in bone plates used in the medical field, elliptical holes have been used to eccentrically place screws for dynamic pressure application; a similar principle can be applied to building support systems to improve insertion flexibility.

[0054] The wide-diameter region 11 can also be a polygonal structure such as a square or hexagon. Insertion is achieved by adjusting the fit between the side length and the size of the narrow-diameter region 12. For example, a square hole can restrict the rotational freedom of the mating part 21, enhance locking stability, and reduce the difficulty of insertion through a chamfer design.

[0055] The wide-diameter region 11 can also be a frustum-shaped structure, wider at the top and narrower at the bottom, similar to a funnel. The radial protrusion of the mating part 21 is slightly smaller than the diameter of the large end of the frustum. During insertion, the mating part 21 is guided in along the taper. The narrow-diameter region 12 can be designed as a circle or other shape that connects to the small end of the frustum. Multi-angle locking is achieved through the taper, which can improve the efficiency of assembly and disassembly.

[0056] The narrow-diameter region 12 can also be an arc-shaped groove, the radius of curvature of which matches the radial protrusion of the mating part 21. For example, an arc-shaped hole allows the mating part 21 to swing within a certain angle range, while locking is achieved through the engagement of the protrusion and the arc-shaped edge. This structure is generally used in impeller locking devices to avoid jamming, and the combination of arc-shaped and flat surfaces improves fault tolerance.

[0057] The narrow-diameter region 12 can also be a wavy or sawtooth structure, and the radial protrusions of the mating part 21 need to be adapted to the shape of the crests / troughs. This design can increase the contact area during locking and improve shear resistance, making it particularly suitable for high-frequency vibration environments. For example, in stage lighting locking devices, the wide and narrow sides of the cam are designed to achieve dynamic locking through arc-shaped grooves; a similar principle can be used for the locking mechanism of wavy holes.

[0058] The present invention does not restrict the shape and structure of the wide diameter region 11 and the narrow diameter region 12, as long as they can meet the core functions: the size of the wide diameter region 11 must be larger than the size of the mating part 21 to allow the mating part 21 to pass smoothly; the size of the narrow diameter region 12 must be smaller than the size of the mating part 21 and connected to the wide diameter region 11 to form a mechanical lock when the mating part 21 moves from the wide diameter region 11 to the narrow diameter region 12; at the same time, the two regions must work together to realize the insertion, locking and removal operations of the mating part 21 to ensure the detachable connection between the anchoring component 10 and the support component 20.

[0059] Specifically, such as Figure 4 As shown, the support assembly 20 is a rigid structure, and the mating part 21 is fixed to one end of the support assembly 20. The mating part 21 has a connected rod and a radial protrusion, and the radial protrusion protrudes from the end of the rod.

[0060] The radial protrusion is provided at the end of the rod, precisely matching the wide and narrow diameter areas 12 of the locking hole, ensuring smooth locking and disassembly.

[0061] Specifically, such as Figure 1 As shown, the detachable support system also includes a load-bearing adjustment component 30, which is connected to the support component 20 and configured to adjust the height to adapt to different elevation requirements, while bearing the upper load.

[0062] Specifically, during the support system installation phase, once the support component 20 is mechanically locked to the anchoring component 10 via the mating part 21 and the locking hole, the load-bearing adjustment component 30 can be connected to the support component 20. The connection can be achieved through plug-in (e.g., a pre-drilled hole at the top of the support component 20, into which the bottom steel pipe 31 of the load-bearing adjustment component 30 is inserted) or bolt fixing, ensuring a stable connection. Subsequently, according to the elevation requirements of the floor slab to be constructed, the height of the load-bearing adjustment component 30 is adjusted: the height of its top bearing surface is changed by rotating the adjusting component (e.g., nut 33), while simultaneously using tools such as a level to calibrate the verticality, ensuring that the load-bearing adjustment component 30 is both perpendicular to the ground and precisely aligned with the bottom of the floor slab. During the load-bearing phase, the top of the load-bearing adjustment component 30 directly bears the upper load, including the floor slab formwork, precast layer, and the self-weight of the concrete, and sequentially transfers the load to the support component 20, the anchoring component 10, and finally distributes it to the wall, forming a complete load chain. When the floor slab construction is completed and the conditions for demolition are met, the height of the load-bearing adjustment component 30 is first lowered to detach it from the floor slab, and then the support component 20 is removed. At this time, the load-bearing adjustment component 30 can be removed together with the support component 20, inspected, and reused. Throughout the process, the load-bearing adjustment component 30 always acts as an "adaptive bridge" between the support component 20 and the floor slab, meeting different elevation requirements while ensuring stable load transfer.

[0063] The load-bearing adjustment component 30 obtains stable support through a rigid connection with the support component 20. Its built-in height adjustment structure (such as threaded drive and telescopic rod) can change its own length to adapt to the elevation difference of different floor slabs. At the same time, the structural design of its load-bearing surface (such as the support 34 and the slot) can directly bear the upper load and transmit the force to the support component 20 through rigid transmission. Finally, the force is transmitted to the wall by the anchoring component 10, taking into account both adaptability and load-bearing reliability.

[0064] Another advantage of this invention is that it solves the problem of insufficient precision caused by the reliance on crude methods such as cutting and raising of uprights for height adjustment in traditional scaffolding support systems. Through adjustable design, it can accurately adapt to different floor slab elevations. At the same time, its synergistic effect with the support component 20 avoids the occupation of lower space by traditional support uprights, reserving space for the early introduction of equipment and parallel construction by multiple trades, and significantly improving construction flexibility.

[0065] More specifically, the load-bearing adjustment assembly 30 includes a steel pipe 31, a top support rod 32, a nut 33, and a support 34. The steel pipe 31 is fixedly connected to the support assembly 20 by a plug-in connection. The support 34 is installed on the top support rod 32. The top support rod 32 is threadedly connected to the nut 33. The inner buckle of the nut 33 directly locks and fixes the steel pipe 31. The nut 33 can be rotated to make the top support rod 32 rise and fall along the axial direction of the steel pipe 31 to adjust the height of the support 34 so as to support the I-beam or engineered wood.

[0066] Specifically, the installation of the load-bearing adjustment component 30 begins with its connection to the support component 20: the bottom of the steel pipe 31 is inserted into the pre-drilled hole at the top of the support component 20, with the steel pipe 31 fitting tightly against the hole wall to form a fixed insertion, ensuring a stable connection without the need for additional fasteners. Subsequently, the top support rod 32 is inserted through the top of the steel pipe 31. A support 34 (such as a steel plate support or a U-shaped groove) is installed at the top of the top support rod 32, and its bottom is threadedly connected to the nut 33. The nut 33 has an inner clip on its inner side to lock the outer wall of the steel pipe 31, preventing the nut 33 from rotating. When height adjustment is required, the nut 33 is rotated. Because the nut 33 is fixed by the inner clip and cannot rotate, its threaded engagement with the top support rod 32 forces the top support rod 32 to rise and fall axially along the steel pipe 31, thereby causing the support 34 to move synchronously until the height of the support 34 matches the floor slab elevation. After adjustment, place I-beams or engineered wood on the support 34 to form a load-bearing transition structure, evenly transferring the floor load to the top support rod 32 and steel pipe 31, and then to the wall via the support assembly 20. During removal, rotate the nut 33 in the opposite direction to lower the top support rod 32, disengaging the support 34 from the I-beams or engineered wood, allowing the load-bearing adjustment assembly 30 to be removed.

[0067] The steel pipe 31 is quickly connected to the support component 20 by plugging it in. The rotational motion is converted into axial lifting by the threaded transmission of the nut 33 and the top support rod 32, so as to achieve precise height adjustment. The inner buckle limits the nut 33 to ensure the stability of the adjustment process. The cooperation between the support 34 and the I-beam / engineering wood realizes the uniform transfer of load. The overall structure takes into account the convenience of connection, adjustment accuracy and load-bearing stability.

[0068] The structural advantages of the load-bearing adjustment component 30 are as follows: First, the hidden locking design of the internal snap-fit ​​nut 33 eliminates the need for traditional external fasteners. The elastic snap-fit ​​inside the nut 33 directly clamps the steel pipe 31, achieving "adjustment by rotation and locking by release," avoiding failure caused by dust contamination and improving reliability in complex construction environments. Second, the synergy between the plug-in and threaded transmission allows for quick connection between the steel pipe 31 and the support component 20 via an interference fit. The threaded engagement between the top support rod 32 and the nut 33 penetrates the interior of the steel pipe 31, increasing the thread force and ensuring a tighter plug-in connection during adjustment. Third, the top support rod 32 serves as both an adjusting screw and a load-bearing member. The rigid connection between the support 34 and the top support rod 32 forms a linear force transmission, eliminating the break in force transmission between the support component 20 and the load-bearing adjustment component 30, thus improving shear strength compared to a split structure.

[0069] A construction method for a detachable support system, based on the detachable support system of Example 1, includes the following steps: (1) Embed the pre-embedded part 14 of the anchoring component 10 into the wall, and clean the locking hole of the anchoring component 10 after the wall is formed.

[0070] (2) The mating part 21 of the support assembly 20 passes through the wide diameter region 11 of the locking hole and moves to the narrow diameter region 12 to form a mechanical lock to fix the support assembly 20.

[0071] (3) Adjust the load-bearing adjustment component 30 connected to the support component 20. By adjusting the height and verticality of the load-bearing adjustment component 30, the load-bearing surface of the load-bearing adjustment component 30 is kept flat.

[0072] (4) Based on the floor slab type, lay templates or precast layers on the bearing surface of the bearing adjustment component 30 and pour concrete.

[0073] (5) After the floor slab reaches the preset strength, the load-bearing adjustment component 30 is lowered so that the load-bearing surface of the load-bearing adjustment component 30 is removed from the floor slab. The mating part 21 of the support component 20 is moved back to the wide diameter area 11 to remove the support component 20 and recycle it for reuse.

[0074] Specifically, in the initial stage of construction, the anchoring component 10 is pre-embedded: after the wall reinforcement is tied, the pre-embedded part 14 of the anchoring component 10 is aligned with the preset position and placed into the reinforcement cage, ensuring that the plate faces outward and the locking hole is unobstructed. Then, concrete is poured to solidify the pre-embedded part 14 with the concrete. After the wall concrete reaches the required strength, the wall formwork is removed, and the concrete slag and debris in the locking hole of the anchoring component 10 are cleaned to ensure that there is no blockage in the hole.

[0075] Next, install the support assembly 20: align the radial protrusion of its mating part 21 with the wide diameter area 11 of the locking hole, smoothly insert it, and move it along the inner channel of the hole to the narrow diameter area 12. At this time, the radial protrusion engages with the hole wall, completing the fixation of the support assembly 20.

[0076] Next, connect and adjust the load-bearing adjustment component 30: plug it into and fix it to the support component 20, adjust the height by rotating the adjustment component, calibrate the verticality with a level, so that the top load-bearing surfaces of multiple load-bearing adjustment components 30 are on the same horizontal plane, ensuring uniform force distribution.

[0077] Construction then proceeds according to the floor slab type: for cast-in-place slabs, a bottom formwork is laid and fixed on the bearing surface before pouring concrete; for precast composite slabs, the precast layer of the composite slab is laid first, followed by pouring the composite layer concrete. Once the concrete reaches its design strength (meeting the demolding requirements), dismantling begins: first, the bearing adjustment component 30 is lowered to detach the bearing surface from the floor slab, and the I-beams or engineered wood are removed; then, the mating part 21 of the support component 20 is moved from the narrow-diameter area 12 back to the wide-diameter area 11, and the support component 20 is removed. Finally, components such as the load-bearing adjustment component 30 and the support component 20 are recovered, inspected for damage, and then used in other construction areas.

[0078] By using pre-embedded anchoring components 10, fixed support components 20, and load-bearing adjustment components 30 for targeted construction, and a streamlined process for dismantling and recycling, the coordinated operation of each component is achieved: the anchoring components 10 provide the basic connection point, the support components 20 transmit the load, the load-bearing adjustment components 30 adapt to the elevation, and the construction steps ensure that each link is connected in an orderly manner, ultimately achieving a full-cycle function of stable installation, efficient construction, and convenient dismantling.

[0079] Specifically, in step (1), the anchoring component 10 is pre-embedded by sealing the locking hole through the sealing unit 13, and the sealing unit 13 is removed after the wall is formed.

[0080] Specifically, before embedding the anchoring component 10, the locking hole must be sealed: a sealing unit 13 (such as a rubber plug, plastic cap, or foam filler block) matching the size of the locking hole is selected and embedded into the locking hole to ensure that the opening is completely sealed, preventing cement slurry, sand, and other debris from entering during concrete pouring. Then, the embedded part 14 of the anchoring component 10 is placed into the wall reinforcement skeleton and fixed in the preset position. During concrete pouring, the sealing unit 13 will block all flowing concrete material from entering the locking hole. After the wall concrete has solidified and reached the design strength, the wall formwork is removed, and the sealing unit 13 is taken out with tools (such as a screwdriver or pliers). At this point, only a small amount of fine dust may remain in the locking hole. Finally, the locking hole is cleaned with a brush or compressed air to ensure it is unobstructed and free of debris, providing a clean passage for the subsequent insertion and locking of the mating part 21 of the support component 20.

[0081] By physically isolating debris from the locking hole during the concrete pouring stage using the sealing unit 13, blockage within the hole is prevented from the outset. This solves the problem of functional failure caused by concrete clogging of holes in traditional pre-embedded connecting components, avoiding the need to discard the anchoring component 10 later due to cleaning difficulties, and reducing construction costs. At the same time, it ensures the integrity of the locking hole, ensuring smooth installation and removal of the support component 20 and improving construction efficiency.

[0082] Specifically, in step (3), the load-bearing adjustment component 30 adjusts the height of the bearing surface of the support 34 on the top support rod 32 by threaded connection between the nut 33 (wing nut 33) and the top support rod 32. The flatness of the bearing surface is achieved by synchronous adjustment of multiple sets of load-bearing adjustment components 30.

[0083] Specifically, after the load-bearing adjustment component 30 is connected to the support component 20, height and flatness adjustments begin. When adjusting the height, the threaded connection between the nut 33 and the top support rod 32 in the load-bearing adjustment component 30 is utilized: holding the nut 33 and rotating it, since the nut 33 is fixed to the steel pipe 31 by an internal clip and cannot move axially, its rotational motion is converted into the axial lifting and lowering of the top support rod 32 through threaded transmission, driving the top support 34 to move synchronously until the height of the support 34 reaches the floor slab design elevation. When adjusting the flatness, for multiple sets of load-bearing adjustment components 30, synchronized operation is required: using the same level to measure the height of each support 34 sequentially, adjusting the support 34 that is lower or higher than the reference plane upwards or downwards respectively, and verifying again after each adjustment until the load-bearing surfaces of all supports 34 are at the same horizontal plane. During this process, the self-locking property of the threaded connection ensures that the height does not spring back after adjustment, and synchronous adjustment avoids uneven floor slab stress caused by localized excessively high or low load-bearing surfaces.

[0084] It solves the problems of poor precision and uneven force caused by adjusting the height of traditional support systems by padding and cutting uprights. The threaded fit controls the height adjustment error to the millimeter level, and synchronous adjustment ensures that the surface of the floor slab is flat after pouring.
