Description

Technical Field

[0001] This invention belongs to the field of civil engineering construction technology, specifically relating to a climbing scaffold support for a fourth-generation building with staggered cantilevered terraces and its installation method. Background Technology

[0002] To create a green, ecological, and three-dimensional space, the fourth-generation architecture widely adopts a staggered cantilevered terrace structure. This structure cantilevered outside the main structure, resulting in a lack of reliable load-bearing points for the traditional climbing scaffold system attached to the main wall. Therefore, it is necessary to install dedicated climbing scaffold support brackets on the staggered cantilevered terraces to provide the necessary attachment and load-bearing foundation for the climbing scaffold. This is a necessary prerequisite for ensuring the safety and progress of the fourth-generation architecture construction.

[0003] Currently, the common technical solution adopted in the industry for this scenario is to erect a custom-made large steel column on the terrace, and then install wall-attached connecting components such as support plates and through-wall bolts between the steel column and the structural wall to connect the steel column to the main structural wall.

[0004] During construction, if the climbing scaffold tilts slightly due to installation issues or uneven load distribution, the wall supports need to be fine-tuned to restore its original position. However, the rigid connection system in existing technology, consisting of support plates, through-wall bolts, and steel columns, has fixed connection points and force transmission angles, lacking the ability to be adjusted on-site. Therefore, if the climbing scaffold tilts, it is impossible to promptly eliminate the additional bending moment and lateral force caused by the initial tilt accumulation. This not only significantly increases the local stress at the support connection nodes and the staggered terrace structure itself but also poses potential structural safety risks. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a fourth-generation building staggered cantilever terrace climbing frame support and its installation method, addressing the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a fourth-generation building staggered cantilever terrace climbing scaffold support, comprising: The main load-bearing steel section is equipped with a pose detection module for acquiring its spatial pose information. The pose detection module is connected to the controller signal, and one side of the main load-bearing steel section is connected to the climbing frame. Horizontal tie rods are installed horizontally between the load-bearing main steel structure and the structural wall. Diagonal tie rods are installed diagonally between the load-bearing main steel structure and the structural wall; The diagonal support rod is installed diagonally between the main load-bearing steel structure and the terrace. The horizontal tie rods, diagonal tie rods, and diagonal support rods are all hydraulic telescopic rods. The hydraulic drive units that control the extension and retraction of the horizontal tie rods, diagonal tie rods, and diagonal support rods are all connected to the controller. The controller controls the hydraulic drive units based on the feedback signal from the posture detection module.

[0007] Preferably, the main load-bearing steel is an H-shaped steel with a web offset. The posture detection module includes a first tilt sensor and a second tilt sensor. Both the first tilt sensor and the second tilt sensor are set on a flange away from the structural wall. The first tilt sensor is set on the upper end of the wide flange of the flange and the second tilt sensor is set on the lower end of the wide flange of the flange.

[0008] Preferably, multiple horizontal first round steel bars are arranged vertically on the outer sides of the wide flanges of the main load-bearing steel section, and second round steel bars are arranged diagonally between two adjacent first round steel bars.

[0009] Preferably, the two wide flanges of the load-bearing main steel section are provided with multiple mounting holes for installing through-wall bolts in the vertical direction.

[0010] Preferably, the horizontal tie rod, the diagonal tie rod, and the diagonal support rod all include a fixed pipe section and a telescopic pipe section coaxially sleeved together. A hydraulic cylinder is installed inside the fixed pipe section. The cylinder body of the hydraulic cylinder is connected to the fixed pipe section, and the piston rod of the hydraulic cylinder is connected to the telescopic pipe section. A miniature hydraulic pump station is installed outside the fixed pipe section. The miniature hydraulic pump station is connected to the hydraulic cylinder through a hydraulic circuit. A pressure sensor and a two-way hydraulic lock are sequentially installed at the oil outlet of the hydraulic circuit. Both the pressure sensor and the two-way hydraulic lock are connected to the controller. The pressure sensor is used to detect its working pressure.

[0011] Preferably, each telescopic pipe section is also equipped with a displacement sensor for detecting its elongation, and the displacement sensor is connected to the controller.

[0012] Preferably, both the fixed pipe section and the telescopic pipe section are hinged to end plates, and both the fixed pipe section and the telescopic pipe section are connected to the load-bearing main steel, structural wall or terrace through the end plates.

[0013] Another technical solution adopted in this invention is a method for installing a wall support for a climbing scaffold on a staggered cantilever terrace in a fourth-generation building, which specifically includes the following steps: When supporting the structural wall formwork, a tapered tube is pre-embedded at the designed position as a sleeve. After the concrete is poured and initially set, the tapered tube is pulled out to form a through reserved hole. After the concrete strength of the terrace slab reaches C15, the main load-bearing steel structure will be hoisted to the designated position and connected to the terrace slab. The horizontal tie rods, diagonal tie rods, and diagonal support rods should be installed in sequence. During installation, the fixed pipe sections corresponding to the horizontal tie rods and diagonal tie rods should be connected to the main structural steel first, then the expansion pipe sections corresponding to the horizontal tie rods and diagonal tie rods should be connected to the structural wall, and finally the fixed pipe sections corresponding to the diagonal support rods should be connected to the cast-in-place slab of the terrace, and the expansion pipe sections corresponding to the diagonal support rods should be connected to the main structural steel. Connect the two ends of the through-wall bolt to the main load-bearing steel section and the pre-drilled holes in the structure, respectively.

[0014] Preferably, when installing horizontal tie rods, diagonal tie rods, or diagonal support rods, first install connecting end plates at the corresponding positions of the load-bearing main steel profile, the terrace cast-in-place slab, or the structural wall, and then hinge the installation end plates to the corresponding fixed pipe section and telescopic pipe section respectively.

[0015] Preferably, when installing the tie rod, the fixed section of the tie rod is connected to the lower side of the load-bearing main steel section, and the telescopic tube of the tie rod is inclined upward and connected to the structural wall.

[0016] Compared with the prior art, the present invention has the following advantages: 1. This invention relates to a fourth-generation staggered cantilever terrace climbing frame support for buildings. The main load-bearing steel section is fixed to the cast-in-place terrace slab, connected to the climbing frame, and then connected to the structural wall via horizontal and diagonal tie rods 3. Finally, the main load-bearing steel section is connected to the terrace via diagonal support rods, thus constructing a three-dimensional spatial support system between the climbing frame and the structural wall. Furthermore, this support system can sense the tilt of the climbing frame; that is, when the tilt sensor installed on the main load-bearing steel section detects that the tilt of the climbing frame causes abnormal posture of the main steel section, the tilt can be corrected by adjusting the extension and retraction of the corresponding rods, eliminating additional bending moments. This fundamentally solves the problems of existing fixed supports being unable to dynamically adapt and difficult to adjust. 2. This invention relates to a fourth-generation staggered cantilever terrace climbing scaffold support for buildings. Displacement sensors are installed on each telescopic pipe section, enabling the system to acquire the absolute length and length change of each support member in real time and with high precision. When the climbing scaffold tilts, the length combination of each tie rod will inevitably change to adapt to the new geometry. The precise length data provided by the displacement sensors, along with the attitude data acquired by the tilt sensor and the force data acquired by the pressure sensor, are cross-checked and fused, allowing the controller to construct a more reliable structural state model. 3. The present invention provides a fourth-generation staggered cantilever terrace climbing scaffold support, which uses hydraulic telescopic tie rods to directly transfer most of the load of the climbing scaffold position to the main structural wall, and only a small portion of the load to the terrace. This keeps the local load on the terrace within the design limit, eliminating the need for additional reinforcement of the terrace and fundamentally avoiding the safety hazards of terrace structural damage and overturning.

[0017] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 as well as Figure 5 As shown, this invention discloses a fourth-generation staggered cantilever terrace climbing scaffold support, comprising: a load-bearing main steel profile 1, a horizontal tie rod 2, an inclined tie rod 3, and an inclined support rod 4. The upper end of the load-bearing main steel profile 1 is equipped with a first tilt sensor for detecting the upper end's posture, and the lower end is equipped with a second tilt sensor for detecting the lower end's posture. Both the first and second tilt sensors are connected to a controller. The controller controls the hydraulic drive unit based on the feedback signals from the first and second tilt sensors. The horizontal tie rod 2 is horizontally positioned between the load-bearing main steel profile 1 and the structural wall 9; the inclined tie rod 3 is obliquely positioned between the load-bearing main steel profile 1 and the structural wall 9; and the inclined support rod 4 is obliquely positioned between the load-bearing main steel profile 1 and the terrace. Furthermore, to facilitate adjustment when the climbing scaffold tilts, the horizontal tie rod 2, the inclined tie rod 3, and the inclined support rod 4 are all hydraulic telescopic rods, and the hydraulic drive unit controlling the extension and retraction of the horizontal tie rod 2, the inclined tie rod 3, and the inclined support rod 4 is connected to the controller.

[0022] This invention discloses a fourth-generation staggered cantilever terrace climbing frame support for buildings. The main load-bearing steel section 1 is fixed to the cast-in-place slab of the terrace. The main load-bearing steel section 1 is connected to the climbing frame, and then connected to the structural wall 9 via horizontal tie rods 2 and diagonal tie rods 3. Finally, the main load-bearing steel section 1 is connected to the terrace via diagonal support rods 4. This creates a three-dimensional spatial support system between the climbing frame and the structural wall 9. Furthermore, this support system can sense the tilt of the climbing frame. Specifically, the tilt sensor installed on the main load-bearing steel section 1 can detect when the tilt causes abnormal posture of the main steel section. By adjusting the extension and retraction of the corresponding rods, the tilt of the climbing frame can be corrected, eliminating additional bending moments. This fundamentally solves the problems of existing fixed supports being unable to dynamically adapt and difficult to adjust.

[0023] Furthermore, such as Figure 4 As shown, the load-bearing main steel section 1 disclosed in this embodiment is an H-shaped steel section with a centrally offset web. The load-bearing main steel section 1 includes two flanges 1-1 on both sides and a web 1-2 located between the two flanges 1-1. The first tilt sensor and the second tilt sensor are both set on one flange away from the structural wall 9, with the first tilt sensor set at the upper end of the wide flange of the flange and the second tilt sensor set at the lower end of the wide flange of the flange. Steel plates for connecting with the terrace concrete are also provided at the bottom of the two flanges. In this embodiment, the load-bearing main steel section 1 adopts an H-shaped steel section with a centrally offset web, which is intended to improve the stability of the support and the reliability of the connection through this asymmetrical structural optimization. The web of the H-shaped steel section with its web offset to one side provides a wider arrangement space when connecting the main load-bearing steel section 1 to the climbing frame of the structural wall 9. This creates a more stable and direct force transmission path, effectively avoiding the connection difficulties or stress concentration problems caused by the flange position limitations of standard symmetrical H-shaped steel sections. Simultaneously, this eccentric structure more specifically optimizes the bending performance of the section, efficiently resisting the main bending moment and reducing the generation of unfavorable torques, ensuring the overall mechanical stability and safety of the support under complex construction loads. Furthermore, by arranging two tilt sensors at the upper and lower ends of the same wide flange of the H-shaped steel section with its web offset away from the structural wall 9, the overall tilt and local bending deformation of this key load-bearing flange plane can be directly monitored. This arrangement effectively distinguishes the overall rigid displacement of the support, providing reliable attitude feedback signals for intelligent leveling based on hydraulic telescopic rods, thus improving the structural safety early warning capability for tilting under complex working conditions.

[0024] Furthermore, in this embodiment, multiple horizontal first round steel bars 6-1 are vertically arranged on the outer sides of the wide flanges of the main load-bearing steel section 1. A second round steel bar 6-2 is diagonally arranged between adjacent round steel bars 6-1, forming a Z-shaped structure. This Z-shaped round steel bar support structure welded to the outer sides of the wide flanges not only forms a highly efficient triangular lattice reinforcement system with the flanges and webs, improving the overall torsional stiffness and lateral stability of the main load-bearing steel section, but also effectively suppresses local buckling and instability deformation under complex loads. Simultaneously, it provides a stable and reliable mounting base and protective frame for the tilt sensor, ensuring the stability of the reference surface and the accuracy of measurement data under construction vibration and impact environments.

[0025] Multiple mounting holes 5 for installing through-wall bolts 8 are vertically arranged on both sides of the wide flanges of the main load-bearing steel section 1. This embodiment, by setting a series of standardized mounting holes on the wide flanges of the main load-bearing steel section, allows the through-wall bolts of the climbing scaffold wall support to pass through the mounting holes and connect directly to the steel section, thus constructing an efficient force transmission path from the climbing scaffold load to the main steel section and avoiding stress concentration caused by connections in the web or narrow areas. Simultaneously, this standardized hole spacing module allows the support to flexibly select the installation position according to different floor heights and climbing scaffold heights, greatly enhancing the versatility and on-site adaptability of the entire support system. This achieves rapid and standardized installation and disassembly of the support while ensuring structural safety.

[0026] The main load-bearing steel section 1 is made of 10mm thick Q235B steel welded into an H-shape with a slightly off-center web (web thickness 10mm, flange dimensions 200mm×10mm, web height 300mm). D33 through holes are opened in the middle of the flanges, with a spacing of 300mm (matching the common through-wall bolt spacing module for climbing scaffold supports). This allows for adjustments based on different floor heights (2.8m, 3.0m, 3.3m). The installation position of the climbing scaffold wall supports is adjusted to suit the floor height requirements of different projects (common floor heights such as 3.6m, etc.). Multiple horizontal first round steel bars 6-1 are welded vertically to the outer sides of the wide flanges of the main load-bearing steel section 1. A second round steel bar 6-2 is diagonally positioned between adjacent round steel bars 6-1, forming a Z-shaped structure. Both the first and second round steel bars 6-1 are φ20 round steel bars, and the distance between adjacent first round steel bars 6-1 is 500mm. This Z-shaped structure increases the overall load-bearing capacity of the H-beam. During the welding of the round steel bars, the welding current is strictly controlled to ensure that the weld is free of defects such as porosity and slag inclusions. After welding, sandblasting and rust removal are performed, followed by spraying with anti-rust primer and chlorinated rubber topcoat. CNC drilling machines are used to machine the through holes in the flanges to ensure the hole diameter and position.

[0027] Furthermore, in this embodiment, the horizontal tie rod 2, the diagonal tie rod 3, and the diagonal support rod 4 all include a fixed pipe section and a telescopic pipe section coaxially sleeved together. A hydraulic cylinder is installed inside the fixed pipe section. The cylinder body of the hydraulic cylinder is connected to the fixed pipe section, and the piston rod of the hydraulic cylinder is connected to the telescopic pipe section. A miniature hydraulic pump station is installed outside the fixed pipe section. The miniature hydraulic pump station is connected to the drive hydraulic cylinder through a hydraulic circuit. A pressure sensor and a two-way hydraulic lock are sequentially installed at the oil outlet of the hydraulic circuit. Both the pressure sensor and the two-way hydraulic lock are connected to the controller. The pressure sensor is used to detect its working pressure. This embodiment integrates a pressure sensor and a two-way hydraulic lock into the drive hydraulic circuit of each hydraulic telescopic rod, enabling the system to monitor the actual axial load of each rod in real time and accurately. When the climbing frame tilts, the load is redistributed unevenly to each tie rod, causing a significant change in its stress state. The pressure sensor can immediately capture this abnormal force distribution by detecting pressure. At the same time, the two-way hydraulic lock can reliably lock the rod length at any adjustment position, ensuring that the stiffness and geometry of the support system remain stable during diagnosis and adjustment. This achieves an intelligent improvement from sensing tilt phenomena to diagnosing the root cause of stress and stabilizing the system.

[0028] The aforementioned hydraulic telescopic poles have a rated tensile and compressive load of 20KN, capable of handling the vertical weight, horizontal wind force, and lateral constraint requirements of the climbing scaffold. The telescopic stroke is 1.5 meters, and the working length can be adjusted between 1.5 and 3 meters, covering various distances between staggered terraces and the main wall, without needing to distinguish between different pole types. Equipped with a 12V electric hydraulic pump station (350W, working pressure 20MPa), installed on the outside of the fixed pipe, it supports 5-10 meter remote control operation for convenient construction. A two-way hydraulic lock is used, which can lock the cylinder after the pole length is adjusted to the correct position, preventing displacement of the telescopic pipe section under load and ensuring stable pole force. Furthermore, each telescopic pipe section is equipped with a displacement sensor to detect its elongation, and the displacement sensor is connected to the controller. By installing displacement sensors on each telescopic pipe section, the system can accurately acquire the absolute length and length change of each support member in real time. When the climbing frame tilts, the length combination of each tie rod will inevitably change to adapt to the new geometry. The precise length data provided by the displacement sensors, along with the attitude data acquired by the tilt sensor and the force data acquired by the pressure sensor, are cross-verified and fused, enabling the controller to construct a more reliable structural state model. This achieves cross-verification of the accuracy of tilt diagnosis, reduces misjudgments, and provides the hydraulic adjustment system with precise length adjustment targets and closed-loop feedback.

[0029] Furthermore, the radial gap between the fixed pipe section and the telescopic pipe section is 0.5-1mm. The inner wall of the fixed pipe section has a groove along its axial direction, and the telescopic pipe section has a protrusion corresponding to the groove. This embodiment precisely controls the radial gap between the fixed and telescopic pipe sections within the range of 0.5-1mm, and provides a guide structure with grooves and protrusions between them. This ensures smooth and unobstructed movement of the telescopic pipe section under hydraulic drive, while suppressing potential radial sway and torsion under pressure or complex loads. This high-precision fit enhances the overall rigidity and movement stability of the telescopic rod as a load-bearing component, and makes length measurements based on displacement sensor feedback more accurate and reliable. Furthermore, for convenient operation, the hydraulic pump station is connected to a wireless remote control module.

[0030] To achieve effective connection between the horizontal tie rod 2, the diagonal tie rod 3, and the diagonal support rod 4 and the load-bearing main steel profile 1, the structural wall 9, and the terrace, this embodiment discloses that the ends of the fixed and telescopic pipe sections of the horizontal tie rod 2, the diagonal tie rod 3, and the diagonal support rod 4 are all hinged with connecting end plates 7. Both the fixed and telescopic pipe sections are connected to the load-bearing main steel profile 1, the structural wall 9, or the terrace through the connecting end plates 7. The connecting end plates are 12mm thick and 120mm × 120mm in size. The end plates have bolt holes (33mm in diameter) matching the through holes of the load-bearing main steel profile and pin holes (31mm in diameter) connecting to both ends of the hydraulic rods. The connecting end plates are detachably connected to the reserved through holes on the flanges of the load-bearing main steel profile and the reserved holes in the fourth-generation building main structural wall 9 (or beam) using M30 high-strength bolts.

[0031] A method for installing a wall support for a cantilevered terrace climbing scaffold in a fourth-generation building, characterized by the following steps: Step 1: When supporting the formwork of structural wall 9, a φ40mm PVC tapered pipe is pre-embedded at the design position. The pre-embedded pipe is fixed and tied firmly with additional steel bars. When pouring concrete, a special person is assigned to watch over the pipe to prevent it from shifting due to the impact of the concrete. Step 2: After the concrete strength of the terrace slab reaches C15, hoist the main load-bearing steel to the designated position and connect the main load-bearing steel to the terrace slab. Before connection, use a level to adjust the verticality of the main load-bearing steel. Then, connect the 10mm thick steel plate at the bottom of the steel to the terrace slab using anchor bolts. Step 3.1: Connect the connecting end plate corresponding to the fixed pipe section of the horizontal tie rod 2 to the top wing plate of the main steel structure using M30 high-strength bolts. Hinge the fixed pipe section of the horizontal tie rod 2 to the connecting end plate using a pin. Then connect the connecting end plate corresponding to the telescopic pipe section of the horizontal tie rod 2 to the structural wall 9. After connection, start the micro hydraulic pump station to control the extension of the telescopic pipe section. Finally, hinge the telescopic pipe section of the horizontal tie rod 2 to the corresponding connecting end plate. Step 3.2: Connect the connecting end plate corresponding to the fixed pipe section of the diagonal tie rod 3 to the lower side of the steel wing plate of the main body with M30 high-strength bolts. Hinge the fixed pipe section of the diagonal tie rod 3 to the corresponding connecting end plate with a pin. Then connect the connecting end plate corresponding to the telescopic pipe section of the diagonal tie rod 3 to the structural wall 9. After connection, start the micro hydraulic pump station to control the extension of the telescopic pipe section. Finally, hinge the telescopic pipe section of the diagonal tie rod 3 to the corresponding connecting end plate. Step 3.3: First, connect the connecting end plate corresponding to the fixed pipe section of the inclined support rod 4 to the cast-in-place slab of the terrace using through bolts. Then, hinge the fixed pipe section to the connecting end plate through a pin. Connect the connecting end plate corresponding to the telescopic pipe section of the inclined support rod 4 to the main structural steel. Then, start the micro hydraulic pump station to control the extension of the telescopic pipe section of the inclined support rod 4, so that the pin hole of the telescopic pipe section end plate is aligned with the pin hole of the connecting end plate on the main structural steel, insert the Φ30mm tie rod pin, and install the cotter pin to achieve the connection. Step 4: Connect the two ends of the through-wall bolt to the mounting holes on the main structural steel 1 and the reserved holes on the structural wall (9), respectively. The two ends of the through-wall bolt are fixed with double nuts. After installation, check the fit between the climbing frame and the support to ensure that the load of the climbing frame can be evenly transferred to the main structural steel.

[0032] When dismantling the aforementioned four-generation building's staggered cantilevered terrace climbing scaffold support, the dismantling should be carried out according to the following method. Preparations before dismantling: After the climbing frame is lowered to the ground, disconnect the power supply to the miniature hydraulic pump station, release the hydraulic system pressure, clean up debris around the supports, and check whether there is rust or jamming at the connection nodes. If there is rust, soak it in rust remover before dismantling. Dismantling sequence: First, remove the through-wall bolts of the climbing scaffold wall support, then remove the diagonal support rods, then remove the top horizontal tie rod 2 and the bottom diagonal tie rod 3 in sequence, and finally remove the anchor bolts at the bottom of the main load-bearing steel section and hoist the steel section to the designated site; Component recycling and maintenance: After dismantling, the components are sorted and cleaned. The cylinders and seals of the hydraulic telescopic rods are thoroughly inspected (if the seals are aged, they are replaced with new ones), and hydraulic oil is added. The main load-bearing steel and connecting components are derusted and repainted to ensure mechanical performance for the next use. All components are stored in a dry and ventilated warehouse with wooden blocks at the bottom to prevent moisture and corrosion.

[0033] In summary, this invention provides a climbing scaffold support for a fourth-generation building's staggered cantilevered terrace. Through hydraulically telescopic tie rods 3, most of the load from the climbing scaffold location is directly transferred to the main structural wall 9, with only a small portion transferred to the terrace. This keeps the local load on the terrace within design limits, eliminating the need for additional terrace reinforcement and fundamentally avoiding the safety hazards of terrace structural damage and overturning. Furthermore, the length adjustment range of the hydraulically telescopic horizontal and diagonal tie rods covers common dimensions of staggered terraces in fourth-generation buildings, eliminating the need for customized processing based on the project. The main load-bearing steel structure adapts to different floor heights through through-holes, and all components are detachably connected via bolts and pins, facilitating transportation and storage. Simultaneously, the support system comprising the climbing scaffold support is a modular structure; individual components are lightweight and compact, requiring no complex installation procedures, and subsequent dismantling only requires manual operation, eliminating the need for large lifting equipment such as tower cranes or hoists, reducing construction costs and improving construction efficiency. Most importantly, the hydraulic system of the hydraulic telescopic tie rod can serve as a temporary adjustment device in emergency situations (such as slight tilting of the climbing frame) to fine-tune the stress state of the support, improve construction safety, and fully adapt to the complex construction needs of the staggered cantilever terraces of fourth-generation buildings.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
