Description

Technical Field

[0001] This invention relates to the field of cantilever components technology, specifically to a support system for cantilever components in high-rise buildings. Background Technology

[0002] Cantilevered components are commonly used load-bearing parts in high-rise building structures, widely applied in balconies, canopies, eaves, and exterior corridors. During on-site construction and prefabrication, these components require external support systems for positioning, fixation, and load bearing to ensure structural stability during concrete pouring and curing. Currently, the industry primarily uses ground-supported scaffolding, single-sided triangular supports, or steel cantilever frames for supporting cantilevered components. However, these support methods have significant limitations in high-rise building construction.

[0003] Traditional support systems mostly use fixed-size members and direct welding or bolting connections, which cannot be flexibly adjusted according to the cantilever length and on-site installation deviations. During construction, multiple adjustments to member lengths and support angles are required, making the overall assembly process cumbersome and time-consuming. Support structures are often unilateral or unidirectionally stressed, lacking overall containment and constraint on the sides and bottom of the cantilever components. During construction, cantilever components are prone to lateral displacement, torsion, and excessive vertical deflection, affecting the structural accuracy.

[0004] The sliding and guiding structures of commonly used support devices are poorly designed, and problems such as jamming, displacement, or even derailment can easily occur during adjustment. Operators need to use additional tools for correction, which increases the difficulty of construction and safety hazards. The fixing method of the support nodes is simple, relying only on bolts or clips for locking. Under vibration and load, they are prone to loosening and cannot maintain a stable support state for a long time.

[0005] Most support systems lack multi-layered bracing and coordinated load-bearing design, resulting in individual members bearing large loads. Long-term use can easily lead to deformation or fatigue damage, resulting in insufficient overall load-bearing capacity and safety margin. Furthermore, the support devices lack auxiliary positioning structures after installation, making them prone to positional rebound before locking, requiring continuous manual support and fixing, thus reducing construction efficiency.

[0006] Traditional support structures involve complex assembly and disassembly procedures, which can easily damage the surface of components during disassembly. This results in low component utilization rates and increases construction material and labor costs. Some support systems are open structures, allowing debris and waste generated during construction to fall from heights, posing a safety threat to the construction area and pedestrians below, while also affecting the cleanliness of the construction site.

[0007] With the promotion of prefabricated buildings and the increasing requirements for high-rise building construction, the existing cantilever component support system can no longer meet the comprehensive needs of rapid assembly, precise positioning, stable load-bearing and safety and environmental protection. A support structure with stronger adaptability, more convenient assembly and more reasonable stress distribution is needed to improve the current construction status.

[0008] Therefore, a support system for cantilevered components in high-rise buildings is proposed. Summary of the Invention

[0009] One of the technical problems that this application aims to solve is that the existing cantilever component support system is inconvenient to adjust, cumbersome to assemble, has insufficient support stability and load-bearing capacity, is difficult to disassemble and assemble, and is prone to the risk of falling objects from heights, and cannot meet the needs of efficient construction and precise positioning of prefabricated high-rise buildings.

[0010] To address the aforementioned technical problems, this application provides a support system for cantilever components in high-rise buildings, including a main beam, a cantilever beam, and a protective support plate. It also includes an L-shaped plate mounted on the protective support plate. Support rod one and tie rods are symmetrically connected to the bottom and outer sides of the L-shaped plate, respectively. The ends of the tie rods and support rod one are provided with rod ends, and the other ends of the tie rods and support rod one are connected to support one and support two, respectively. Support one and support two are connected to the main beam via fasteners. The cantilever beam extends beyond the main beam, and the protective support plate covers the bottom and horizontal sides of the cantilever beam. A horizontal tie rod 1 and a horizontal tie rod 2 are provided between the support rods 1. A vertical tie rod 1 is provided on the horizontal tie rod 1, and a vertical tie rod 2 is provided on the horizontal tie rod 2.

[0011] In some embodiments, a sliding groove is provided on the bottom and outer side of the protective support plate near the cantilever end of the cantilever beam, and guide ridges are provided on the inner sidewall and the upper and lower sidewalls of the sliding groove.

[0012] In some embodiments, reinforcing ribs are provided on both the outer and bottom sides of the L-shaped plate, and the reinforcing ribs are hinged to the end of the rod.

[0013] In some embodiments, the horizontal tie rod 1 is provided with connector 3 at both ends, the connector 3 is provided on the support rod 1, and the middle part of the horizontal tie rod 1 is provided with several connector 2. The vertical tie rod 1 is rotatably connected to the horizontal tie rod 1 through the connector 2.

[0014] In some embodiments, the horizontal tie rod 2 is provided with a connector 1 at one end, the connector 1 is provided on the support rod 1, the position of the connector 1 is higher than the position of the connector 3, the horizontal tie rod 2 is provided with a plurality of connectors 4, the connectors 4 are connected to the vertical tie rod 2, and the vertical tie rod 1 and the horizontal tie rod 1, and the vertical tie rod 2 and the horizontal tie rod 2 form an inverted T-shaped support structure.

[0015] In some embodiments, the other end of the vertical tie rod one and the vertical tie rod two is provided with an end head, the end head is rotatably mounted on the connecting shaft, the connecting shaft is fixedly mounted between the side plates, and the side plates are fixedly mounted on the bottom horizontal plate one and the bottom horizontal plate two.

[0016] In some embodiments, bottom horizontal plate one is connected to vertical tie rod one, bottom horizontal plate two is connected to vertical tie rod two, bottom horizontal plate one and bottom horizontal plate two are slidably disposed at the bottom of the protective support plate, bottom horizontal plate one and bottom horizontal plate two are provided with through groove two, and a matching guide strip is provided in through groove two. The guide strip is fixed to the bottom of the protective support plate, and a limiting plate is provided at the front of bottom horizontal plate two. Magnets with opposite magnetic properties are provided on the contact parts of the limiting plate and the inner side of the L-shaped plate on both sides.

[0017] In some embodiments, sliders are fixedly provided on the inner side and bottom side of the L-shaped plate near the protective support plate, and the sliders are provided with a second groove, which matches the guide ridge.

[0018] In some embodiments, a connecting groove is provided on the L-shaped plate, the connecting groove passes through the L-shaped plate, the slider enters the outer side and bottom side of the protective support plate, and a bolt is provided in the connecting groove.

[0019] In some embodiments, the tie rod, support rod one, vertical tie rod one, and vertical tie rod two are telescopic rods.

[0020] This invention has at least the following beneficial effects: 1. This support system is applied to the construction of cantilever components in high-rise buildings. It provides bottom and horizontal support for the cantilever beam, improving its overall rigidity during installation and pouring, and reducing lateral deformation and vertical deflection under stress. The sliding groove and guide ridge on the support plate cooperate with the slider and sliding groove on the L-shaped plate to ensure smooth sliding of the L-shaped plate along a preset path, reducing the probability of jamming during sliding and improving the smoothness of assembly operations.

[0021] 2. By designing the tie rod and support rod one as a telescopic structure, their lengths can automatically adjust with changes in the support angle during the sliding of the L-shaped plate, adapting to different cantilever lengths and installation deviations, thus improving the versatility and adaptability of the components. Horizontal tie rod one and horizontal tie rod two, together with vertical tie rod one and vertical tie rod two, form a stable support structure that can distribute the support force, avoid local stress concentration, and improve the overall stability of the support system.

[0022] 3. Vertical tie rod one and vertical tie rod two are rotatably connected to the connecting shaft at their ends. This allows for synchronized adjustment of the support posture as the bottom horizontal plate slides, ensuring that the direction of force applied to the support always aligns with the stress requirements of the protective support plate, thus enhancing the effectiveness of the support. The bottom horizontal plate slides in conjunction with the guide strip through slot two, ensuring a stable movement path for the vertical tie rods and preventing offset or misalignment of the support members during extension and rotation.

[0023] 4. Magnets with opposite magnetic properties are installed on the inner sides of the limiting plate and the L-shaped plate. After the L-shaped plate slides into place, it achieves magnetic positioning, helping to maintain the stability of the support frame and reducing component displacement before the bolts are tightened. Once the bolts pass through the connecting groove, they fix the L-shaped plate, the slider, and the protective support plate as a whole, keeping the support structure in a fixed state after sliding adjustment and ensuring the reliability of the support during construction.

[0024] 5. The tie rods provide continuous horizontal ties to the protective support plate, limiting its outward displacement and improving the fit between the cladding structure and the cantilever beam. Support rod one, vertical tie rod one, and vertical tie rod two jointly bear the vertical load, sharing the self-weight of the cantilever beam and additional construction loads, reducing the stress on individual members and enhancing the load-bearing capacity of the support system.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0028] Example 1, see Figures 1-10 This invention provides a technical solution: a support system for cantilever components of high-rise buildings, including a main beam 100, a cantilever beam 200, and a protective support plate 300, and also including an L-shaped plate 307 disposed on the protective support plate 300. The bottom side and the outer side of the L-shaped plate 307 are symmetrically connected to a first support rod 302 and a tie rod 301, respectively. The ends of the tie rod 301 and the first support rod 302 are provided with rod ends 308. The other ends of the tie rod 301 and the first support rod 302 are respectively connected to a first support 303 and a second support 304. The first support 303 and the second support 304 are connected to the main beam 100 by fasteners. The cantilever beam 200 extends beyond the main beam 100, and the protective support plate 300 covers the bottom and horizontal sides of the cantilever beam 200. A horizontal tie rod 312 and a horizontal tie rod 316 are installed between support rods 302. A vertical tie rod 313 is installed on the horizontal tie rod 312, and a vertical tie rod 318 is installed on the horizontal tie rod 316. The tie rods 301, support rods 302, vertical tie rods 313 and 318 are telescopic rods.

[0029] Specifically, with the main beam 100 as the load-bearing foundation and the cantilever beam 200 as the protected and supported object, the cantilever beam 200 is constrained at the bottom and sides by the protective support plate 300, ensuring that the cantilever beam 200 maintains a stable spatial posture during installation and pouring. The L-shaped plate 307, as the core transmission and connection component, can simultaneously drive the tie rod 301 and the first support rod 302 to move synchronously, ensuring consistent support action at the sides and bottom, and avoiding stress imbalance caused by asynchronous movement of different members. The rod end 308 forms a reliable hinge with the reinforcing rib plate 309, ensuring smooth rotation of the tie rod 301 and the first support rod 302 when their length and angle change, making the load transfer path continuous and clear. Support 1 303 and support 2 304 are fixed to the main beam 100, directly transferring the load borne by the tie rod 301 and the first support rod 302 to the main structure, improving the overall load-bearing reliability of the support system.

[0030] The protective support plate 300 covers the bottom and horizontal sides of the cantilever beam 200, which can limit the vertical sinking and lateral displacement of the cantilever beam 200, and at the same time provide a stable installation foundation for subsequent support components, preventing the cantilever beam 200 from torsional deformation under construction loads. The horizontal tie rods 312 and 316 installed between the support rods 302 can constrain the spacing between the two support rods 302, preventing the support rods 302 from buckling outwards and becoming unstable under compression. The horizontal tie rods 312 and 313, and the horizontal tie rods 316 and 318 work together to form a continuous support structure in the bottom support area, allowing the vertical load to be evenly distributed across multiple members, reducing the risk of structural damage caused by localized stress concentration.

[0031] The tie rod 301, support rod 302, vertical tie rod 313, and vertical tie rod 318 are designed as telescopic rods, which can adapt to the construction needs of different cantilever lengths. Simultaneously, they automatically adjust to changes in the support angle and distance during the movement of the L-shaped plate 307, eliminating the need for on-site cutting or replacement of rods. The telescopic structural design can compensate for dimensional deviations caused by construction and installation, ensuring a tight fit between the support system and the cantilever beam 200 and main beam 100, improving support accuracy and structural integrity. Vertical tie rod 313 and vertical tie rod 318, used in conjunction with horizontal tie rods, can form multiple layers of vertical support, further reducing the deflection deformation of the cantilever beam 200 and improving the quality of construction.

[0032] The overall layout forms a spatial force-bearing system combining horizontal ties and vertical supports. Tie rod 301 bears the horizontal tensile force, restricting the outward movement of the protective support plate 300. Support rod 302, vertical tie rod 313, and vertical tie rod 318 jointly bear the vertical compressive force, supporting the self-weight of the cantilever beam 200 and the construction load. The mutual constraints and coordinated force-bearing among the components significantly improve the stiffness and stability of the support system, reducing structural displacement during installation and pouring. The entire support system relies on the mechanical cooperation between components for assembly and adjustment, simplifying the operation and increasing construction efficiency. It also facilitates disassembly and reuse, effectively reducing the cost and safety risks of constructing cantilever components in high-rise buildings.

[0033] Example 2, see Figure 1-10 The protective support plate 300 has a sliding groove 305 at its bottom and outer side near the cantilever end of the cantilever beam 200. The inner side wall and upper and lower side walls of the sliding groove 305 have guide ribs 306. The outer side and bottom side of the L-shaped plate 307 are provided with reinforcing ribs 309, which are hinged to the rod end 308. The horizontal tie rod 312 has connectors 315 at both ends, which are mounted on the support rod 302. The middle part of the horizontal tie rod 312 has several connectors 314. The vertical tie rod 313 is rotatably connected to the horizontal tie rod 312 through the connectors 314. A connector 311 is provided at the end of the second horizontal tie rod 316. The connector 311 is mounted on the first support rod 302 and is positioned higher than the third connector 315. Several fourth connectors 317 are provided on the second horizontal tie rod 316. The fourth connectors 317 are connected to the second vertical tie rod 318. The first vertical tie rod 313 and the first horizontal tie rod 312, and the second vertical tie rod 318 and the second horizontal tie rod 316 form an inverted T-shaped support structure. The other end of the first vertical tie rod 313 and the second vertical tie rod 318 is provided with an end cap 329. The end cap 329 is rotatably mounted on the connecting shaft 330. The connecting shaft 330 is fixedly mounted between the side plates 328. The side plates 328 are fixedly mounted on the first bottom horizontal plate 319 and the second bottom horizontal plate 320.

[0034] Specifically, the bottom and outer side of the protective support plate 300 near the cantilever end of the cantilever beam 200 are provided with a sliding groove 305, which provides a limited movement path for the L-shaped plate 307, ensuring that the L-shaped plate 307 can only slide along the extension direction of the cantilever beam 200, thus preventing deviation or swaying during adjustment. Guide ribs 306 are provided on the inner and upper / lower side walls of the sliding groove 305, which reduces the contact area of ​​the L-shaped plate 307 during sliding, lowers sliding resistance, and further constrains the movement direction of the L-shaped plate 307, maintaining the smoothness of the sliding process and preventing jamming or derailment.

[0035] Reinforcing ribs 309 are provided on both the outer and bottom sides of the L-shaped plate 307, which can improve the structural strength of the connection between the L-shaped plate 307 and the rod end 308, and prevent local deformation or tearing during long-term stress or adjustment. The reinforcing ribs 309 and the rod end 308 are connected by hinges, which allows the tie rod 301 and the support rod 302 to freely adjust their angles when moving with the L-shaped plate 307, ensuring smooth force transmission and preventing additional stress due to angle changes, so that the support system is always in a reasonable stress state.

[0036] Horizontal tie rod 312 is fixed to support rod 302 via connector 315, connecting the two support rods 302 into a whole, preventing them from separating outwards under pressure, and improving the overall stability of the bottom support. Multiple connectors 314 are provided in the middle of the horizontal tie rod 312 to connect to the vertical tie rod 313 and achieve rotational engagement, allowing the vertical tie rod 313 to rotate flexibly during extension and angle adjustment, adapting to changes in the support posture and ensuring the continuous effectiveness of the vertical support.

[0037] Horizontal tie rod 2 316 is fixed to support rod 1 302 via connector 1 311, and its installation position is higher than connector 3 315, which can form a layered tie in the vertical direction, further enhancing the overall rigidity of support rod 1 302. Multiple connectors 4 317 are provided on horizontal tie rod 2 316 for connecting vertical tie rod 2 318, allowing vertical tie rod 2 318 to rotate and adjust according to the support state, maintaining a stable support angle. Vertical tie rod 1 313 and horizontal tie rod 1 312, and vertical tie rod 2 318 and horizontal tie rod 2 316 form an inverted T-shaped support structure, which can expand the effective range of the vertical support, evenly distribute the load over a larger area, reduce local load concentration, and improve the overall load-bearing capacity of the support.

[0038] The ends of vertical tie rod 1 313 and vertical tie rod 2 318 are provided with end caps 329, which are installed between side plates 328 via connecting shafts 330. This allows vertical tie rod 1 313 and vertical tie rod 2 318 to rotate smoothly during adjustment, maintaining a reasonable support angle. The side plates 328 are fixed to the bottom horizontal plates 1 319 and 2 320, providing a stable support base for vertical tie rod 1 313 and vertical tie rod 2 318. This ensures that the vertical support force can be smoothly transmitted to the protective support plate 300, while preventing lateral displacement of the vertical tie rods during movement and extension, maintaining the structural stability and force balance of the entire support system.

[0039] Example 3, see Figure 1-10The bottom horizontal plate 319 is connected to the vertical tie rod 313, and the bottom horizontal plate 320 is connected to the vertical tie rod 318. Both the bottom horizontal plate 319 and the bottom horizontal plate 320 are slidably mounted on the bottom of the protective support plate 300. Both the bottom horizontal plate 319 and the bottom horizontal plate 320 are provided with a through groove 327, and a matching guide strip 321 is provided in the through groove 327. The guide strip 321 is fixed to the bottom of the protective support plate 300. The bottom horizontal plate 320 has a limiting plate 322 at the front. Magnets with opposite magnetic properties are provided on both sides of the limiting plate 322 in contact with the inner side of the L-shaped plate 307. The inner side and bottom side of the L-shaped plate 307 near the protective support plate 300 are fixedly provided with sliders 325. The sliders 325 are provided with a sliding groove 324, which matches the guide rib 306. The L-shaped plate 307 is provided with a connecting groove 323, which passes through the L-shaped plate 307 and the slider 325 and enters the outer side and bottom side of the protective support plate 300. A bolt 310 is provided in the connecting groove 323.

[0040] Specifically, bottom horizontal plate 319 is connected to vertical tie rod 313, and bottom horizontal plate 320 is connected to vertical tie rod 318. This allows the supporting force of the vertical tie rods to be smoothly transferred to the bottom area of ​​the protective support plate 300, resulting in a more uniform distribution of the supporting force. Bottom horizontal plate 319 and bottom horizontal plate 320 are slidably installed at the bottom of the protective support plate 300, allowing them to move synchronously with the L-shaped plate 307, ensuring that the vertical tie rods maintain the same motion state as the overall support system.

[0041] Through groove 326 and through groove 327 are respectively opened on bottom horizontal plate 319 and bottom horizontal plate 320. Guide strip 321, which is fixed to the bottom of protective support plate 300, is installed inside through groove 327. This can limit the sliding path of bottom horizontal plate 319 and bottom horizontal plate 320, avoid lateral deviation or jamming during movement, and ensure smooth completion of sliding adjustment.

[0042] A limiting plate 322 is provided at the front of the bottom horizontal plate 320. Magnets with opposite magnetic properties are provided at the contact positions between the limiting plate 322 and the inner side of the L-shaped plate 307. After the L-shaped plate 307 slides into place, a magnetic attraction is formed, so that the L-shaped plate 307 and the limiting plate 322 maintain a stable fit, reducing the possibility of springback or displacement of components before bolt tightening, and improving the positioning accuracy during assembly.

[0043] A slider 325 is fixedly installed on the inner and bottom sides of the L-shaped plate 307 near the protective support plate 300. A second groove 324 is opened on the slider 325. The second groove 324 matches the guide rib 306 in the first groove 305, which allows the L-shaped plate 307 to slide smoothly along the preset direction, while restricting the up-down and left-right movement of the L-shaped plate 307 during sliding, thereby improving the stability and reliability of the overall adjustment process.

[0044] A connecting groove 323 is provided on the L-shaped plate 307. The connecting groove 323 passes through the L-shaped plate 307 and the slider 325 and extends to the outer side and the inner bottom side of the protective support plate 300. A bolt 310 is installed in the connecting groove 323. After the L-shaped plate 307 is adjusted into place, it can be firmly locked to the protective support plate 300, so that the entire support system maintains a fixed working state and avoids loosening or displacement under load.

[0045] The combination of sliding fit and magnetic positioning simplifies the on-site assembly of the support system, reduces the need for manual positioning, and improves construction efficiency. Multiple guiding and locking structures work together to enhance the structural stability and load-bearing capacity of the support system during use, reducing the probability of component failure or positioning deviations during construction. The dual positioning method, combining magnetic-assisted positioning and rigid bolt fixing, balances ease of adjustment with reliability, ensuring the support system maintains sufficient structural strength while allowing for rapid assembly.

[0046] The following is combined with Figures 1-10 Explain its working process: First, install fixed supports 303 and 304 at the preset positions of the main beam 100, and then cover and install the protective support plate 300 on the bottom and horizontal sides of the cantilever beam 200 to complete the three-sided protection and stiffness enhancement of the cantilever beam 200. The ends of the tie rod 301 and the support rod 302 away from the cantilever end are respectively hinged to the support 303 and the support 304. The rod ends 308 of the tie rod 301 and the support rod 302 near the cantilever end are hinged to the reinforcing rib plate 309 on the L-shaped plate 307. The L-shaped plate 307 is pushed along the first slide groove 305 on the protective support plate 300, and slides from the side near the main beam 100 toward the cantilever end of the cantilever beam 200. The slider 325 on the L-shaped plate 307 cooperates with the guide rib 306 in the first slide groove 305 through the second slide groove 324 to achieve directional and smooth sliding until the L-shaped plate 307 slides to the tail end of the first slide groove 305. During this sliding process, the angle between tie rod 301, support rod 1 302 and main beam 100 increases from small to large. Tie rod 301 and support rod 1 302 extend synchronously with the traction of L-shaped plate 307. At the same time, vertical tie rod 1 313 is connected to bottom horizontal plate 1 319 and vertical tie rod 2 318 is connected to bottom horizontal plate 2 320. The sliding of L-shaped plate 307 causes bottom horizontal plate 1 319 and bottom horizontal plate 2 320 to slide synchronously towards the cantilever end of cantilever beam 200 through through slot 2 327 and guide strip 321. This causes vertical tie rod 1 313 and vertical tie rod 2 318 to extend synchronously and rotate clockwise around connecting shaft 330 through end 329, thus completing the adaptive adjustment of support angle and length. After the L-shaped plate 307 has slid into place, insert the bolt 310 into the connecting groove 323 on the L-shaped plate 307, and screw it through the slider 325 into the protective support plate 300. The L-shaped plate 307 and the protective support plate 300 are rigidly fixed by the threaded locking. At this time, the magnets on both sides of the limiting plate 322 at the front of the bottom horizontal plate 320 attract each other to the magnets on the inner side of the L-shaped plate 307, so that the L-shaped plate 307, the limiting plate 322 and the tie rod 301 form an overall horizontal tie frame. The support rod 302, the vertical tie rod 313 and the vertical tie rod 318 form a vertical overall support frame. The tie rod 301 provides horizontal tie force to both sides of the protective support plate 300. The support rod 302, the vertical tie rod 313 and the vertical tie rod 318 together provide vertical support force to the protective support plate 300 and the cantilever beam 200. The multi-directional coordinated force completes the assembly and working lock of the high-rise building cantilever component support system.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
