A tower crane attachment device for super high-rise building core tube construction

Abstract

This invention aims to improve the adaptability of tower crane attachment devices for the construction of core tubes in super high-rise buildings. It provides a tower crane attachment device for core tube construction in super high-rise buildings, including a pre-embedded component connected to the core tube. The pre-embedded component is connected to an adjustable-length wall-mounted member via a ball joint assembly. The wall-mounted member is connected to the tower crane body via a flange assembly. The wall-mounted member is a hydraulic push rod. As the construction of the core tube of a super high-rise building progresses, traditional tower crane attachment devices are time-consuming to adjust. This device, by connecting the wall-mounted member through the pre-embedded component and flange assembly, facilitates assembly and adjustment, resulting in high construction efficiency and low construction cost. Furthermore, as the cross-section of the core tube changes during construction, traditional tower crane attachment devices cannot adapt to changes in spacing. The wall-mounted member in this device is not only adjustable in length but also allows the ball joint assembly to adapt to changes in tilt angle, thus having a wide range of applications and reliable connection.

Description

Technical Field

[0001] This utility model relates to the technical field of tower crane attachment devices, and in particular to a tower crane attachment device used for the construction of the core tube of a super high-rise building. Background Technology

[0002] During the construction of the core tube of a high-rise building, the tower crane, as a key vertical transportation device, needs to be connected to the core tube wall through attachment supports to ensure the stability and safety of the tower crane during high-altitude operations. As high-rise buildings develop towards super high-rise and complex structures, the core tube design often adopts a variable cross-section form (the cross-sectional dimensions become thicker or thinner or eccentric offset during construction), and traditional tower crane attachment supports can no longer meet the construction requirements.

[0003] Existing tower crane attachment supports are mostly rigid structures with fixed lengths and angles. Their dimensions and installation angles are determined at the factory and cannot be flexibly adjusted according to changes in the core tube cross-section. When the core tube construction reaches a section where the cross-section becomes thicker, thinner, or eccentric, the original attachment supports must be removed, and new supports adapted to the current cross-section dimensions must be fabricated and installed at height. This process not only consumes a large amount of manpower and material resources, but also poses safety risks such as falls and falling objects due to frequent high-altitude dismantling and assembly operations. Furthermore, dismantling and assembly operations cause tower crane downtime, seriously affecting the construction progress.

[0004] Furthermore, during the actual construction of the core tube, the actual distance between the tower crane and the core tube wall often deviates from the design value due to factors such as concrete pouring errors, formwork installation deviations, or temporary adjustments to the design scheme. This can easily cause the tower crane's suspension height to exceed the safe range stipulated in the "Safety Regulations for Tower Cranes." If the tower crane is suspended too high, the stress state of the tower crane boom will deteriorate, making it prone to bending and deformation under lifting loads. In severe cases, it may even lead to boom breakage, causing a major safety accident. If the suspension height is forcibly adjusted, it is necessary to rely on manual on-site measurement and calculation, and to achieve fine-tuning through repeated disassembly and assembly of support components. A single adjustment process usually takes 2-3 days, resulting in extremely low adjustment efficiency and further exacerbating the problem of construction delays.

[0005] In summary, current traditional fixed tower crane attachment supports suffer from problems such as difficulty in adapting to changes in the core tube cross-section, significant risks in height control, and low efficiency of manual adjustments. These issues severely restrict the safety, efficiency, and economy of core tube construction in high-rise buildings, necessitating a tower crane attachment support technology solution that can address these problems.

[0006] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of this utility model, and should not be regarded as an admission or in any form implying that the above technical information constitutes prior art known to those skilled in the art.

[0014] Based on the above technical solutions, as a preferred technical solution for the tower crane attachment device used in the construction of the core tube of a super high-rise building, the pre-embedded component includes a double-ended bolt that interlocks with the outer wall of the core tube of the super high-rise building. The two ends of the double-ended bolt are respectively inserted with an inner steel plate and an outer steel plate for clamping the outer wall. The inner steel plate and the outer steel plate are fixed by a locking nut that is compatible with the double-ended bolt.

[0015] Based on the above technical solutions, as a preferred technical solution for the tower crane attachment device used in the construction of the core tube of super high-rise buildings, rubber shock-absorbing pads are provided between the inner steel plate and the inner wall of the outer wall, and between the outer steel plate and the outer wall of the outer wall.

[0017] Based on the above technical solutions, as a preferred technical solution for the tower crane attachment device used in the construction of the core tube of super high-rise buildings, one end of the double-headed bolt located on the inner side of the outer wall is connected to a locking nut, and the other end pressed against the outer side of the ball head hinge seat is connected to three locking nuts.

[0019] Compared with the prior art, the tower crane attachment device for the construction of the core tube of a super high-rise building provided by this utility model has the following beneficial effects:

[0020] 1. As the construction of the core tube of super high-rise buildings progresses, the adjustment of traditional tower crane attachment devices is time-consuming. This device connects the wall-mounted members through pre-embedded components and flange components, which facilitates assembly and adjustment, thus resulting in high construction efficiency.

[0021] 2. As the construction of the core tube of a super high-rise building progresses, its cross-section changes. Traditional tower crane attachment devices cannot adapt to the changes in spacing.

Therefore, it has a wide range of applications and reliable connection.

[0022] 3. As the construction of the core tube of the super high-rise building progresses, its cross-section changes. Traditional tower crane attachment devices require additional reinforcement structures, while this device only requires adjusting the length of the wall-mounted members.

[0023] 4. As the construction of the core tube of a super high-rise building progresses, its cross-section changes. Traditional tower crane attachment devices require more manpower and equipment, resulting in high costs for each adjustment. In contrast, the application cost of this device is low.

[0051] To clearly present the application and optimization direction of the tower crane attachment device in different scenarios, five implementation examples will be designed from the dimensions of basic application, structural optimization, and adaptation to special working conditions. Each implementation example focuses on 1-2 core technical points, combined with specific structural parameters, assembly methods and working principles, to demonstrate the adaptability of the device to the construction of ultra-high-rise core tubes.

[0052] Example 1: Horizontal Layout Tower Crane Attachment Device

[0053] Applicable scenarios: Super high-rise projects with regular core tube cross-sections, no obvious eccentricity, and small changes in the spacing between construction stages, such as residential core tubes with a height of 100-200m.

[0054] Structural composition

[0055] Embedded component 2: M36 double-ended bolts 21 are used, along with a 20mm thick Q345 inner steel plate 22 and an outer steel plate 23. The inner and outer steel plates are both 300mm×300mm in size. An 8mm thick nitrile rubber shock-absorbing pad 25 is attached between the inner steel plate and the inner wall of the core tube outer wall 11, and between the outer steel plate and the outer wall. The steel plate is fixed to the wall by two M36 locking nuts 24.

[0056] Ball joint assembly 3: The ball joint seat 31 is made of cast steel ZG270-500 with a ball radius of 50mm; the hinge ball head 32 is welded and fixed to the hydraulic push rod, i.e. the wall-mounted rod 4, with a clearance of 0.5-1mm between the ball surface and the hinge seat, so as to achieve an angle adjustment of 0-30°.

[0057] Wall-mounted rod 4: Select a single-stage hydraulic push rod with a stroke of 500mm and a rated thrust of 100kN, a cylinder diameter of 120mm, a rod diameter of 80mm, and a material of 20# seamless steel pipe with chrome plating for rust prevention.

[0058] Flange assembly 5: Flange plate 1 51 is welded to the end of the hydraulic push rod, and flange plate 2 52 is welded to the tower crane body 6. Both flange plates are 20mm thick Q345 steel plates with dimensions of 250mm×250mm. They are connected by 6 sets of M24 high-strength bolts 53 with a preload torque of 450N・m.

[0059] Assembly and working principle

[0060] Double-ended bolts 21 are pre-embedded during the pouring of the outer wall 11 of the core tube. After the concrete strength reaches C30, inner and outer steel plates and rubber shock-absorbing pads are installed and tightened with lock nuts 24.

[0061] Slide the ball head hinge seat 31 onto the outer end of the double-ended bolt and press it in place with three locking nuts 24 to prevent loosening. Assemble the hinge ball head 32 with the ball head hinge seat.

[0062] The hydraulic push rod is connected to the hinged ball head 32 and the flange plate 51 at both ends. After the flange plate 52 is fixed to the tower body 6, the length is adjusted by the hydraulic push rod with an adjustment accuracy of ±2mm, so that the distance between the tower body and the core tube meets the design value, such as 3.5m.

[0063] When the core tube cross-section becomes thinner, such as when the spacing increases to 3.8m, it can be adapted without disassembly, simply by extending the hydraulic push rod. The adjustment process takes ≤1 hour.

[0064] Beneficial effects

[0065] The horizontally arranged hydraulic push rods can quickly adapt to changes in the horizontal spacing of the core tube, avoiding the need for disassembly and assembly of traditional supports.

[0066] Rubber shock absorbers reduce the transmission of tower crane vibrations to the core tube wall, protecting the wall structure.

[0067] Example 2: Inclined-Horizontal Combined Arrangement Tower Crane Attachment Device

[0068] Applicable scenarios: Super high-rise projects with a small eccentricity in the core tube section, with an eccentricity of ≤500mm, and requiring improved resistance to lateral displacement, such as the core tube of an office building with a height of 200-300m.

[0069] Structural optimization compared to Example 1

[0070] Wall-mounted member arrangement: A total of 4 sets of wall-mounted members are provided, of which 2 sets are arranged horizontally at the middle height of the tower body with a spacing of 3.6m, and 2 sets are arranged at an angle, located at the upper and lower parts of the tower body respectively, at an angle of 45° with the horizontal direction, and the angle direction is pointing towards the eccentric side of the core tube.

[0071] Hydraulic actuator parameters: The rated thrust of the inclined hydraulic actuator is increased to 120kN and the stroke is 600mm to balance the eccentric load.

[0072] Flange assembly reinforcement: Three 16mm thick triangular ribs made of Q345 material are added between flange plate 1 (51) and flange plate 2 (52) to improve the shear resistance of the flange connection.

[0073] Working principle

[0074] Horizontal members bear the horizontal load of the tower body, while inclined members bear the torque and vertical component of the force caused by eccentricity.

[0075] When the core tube is eccentrically offset, the length of the inclined members is adjusted. For example, when the eccentricity increases to 600mm, the inclined members on the eccentric side are extended by 50mm and the members on the other side are shortened by 50mm. The verticality of the tower body is corrected in real time to ensure that the tower crane suspension height meets the requirements of GB5144-2021 "Safety Regulations for Tower Cranes" (suspension height ≤ 2m).

[0076] Beneficial effects

[0077] The combined arrangement of the lifting device enhances its resistance to lateral displacement and torsion, making it suitable for core tube eccentricity conditions.

[0078] No additional structural reinforcement is required; eccentric loads can be balanced simply by adjusting the length of the members.

[0079] Example 3: Long-stroke vibration-damping tower crane attachment device

[0080] Applicable scenarios: Super high-rise projects with large variations in core tube cross-section and spacing variation ≥800mm, and high requirements for vibration control, such as hotel core tubes with transfer layers.

[0081] Structural optimization compared to Example 1

[0082] Embedded components: The double-ended bolt 21 specification has been upgraded to M40, the inner and outer steel plate dimensions have been increased to 400mm×400mm, and the thickness is 25mm. The rubber shock-absorbing pad 25 adopts a multi-layer composite structure, nitrile rubber + metal mesh, with a total thickness of 12mm, which improves shock absorption and load-bearing capacity.

[0083] Wall-mounted rods: adopt a two-stage hydraulic push rod with a stroke of 1000mm, a rated thrust of 150kN, a cylinder diameter of 150mm, a rod diameter of 100mm, and a built-in displacement sensor with an accuracy of ±0.5mm, providing real-time feedback on the length adjustment.

[0084] Ball joint assembly: The ball radius of the ball joint seat 31 is increased to 80mm, and the surface of the ball joint 32 is coated with polytetrafluoroethylene to reduce the coefficient of friction and expand the angle adjustment range to 0-60°.

[0085] Working principle

[0086] When the core tube was constructed to the transfer layer, the cross-section suddenly changed from 4m×4m to 6m×6m, and the distance between the tower and the wall increased from 3m to 4.2m. The large stroke characteristics of the double-stage hydraulic push rod were used to complete the 1.2m length adjustment in one go without the need for segmented disassembly and assembly.

[0087] Displacement sensors transmit member length data in real time, which, combined with the tower crane verticality monitoring system, enables closed-loop control of "length adjustment - verticality correction," avoiding repeated manual measurements.

[0088] Multi-layer composite rubber shock absorbers reduce tower crane vibration amplitude from 5mm to below 2mm using traditional devices, protecting pipelines and decorative structures within the core tube.

[0089] Beneficial effects

[0090] The long stroke design adapts to large cross-sectional changes, improving adjustment efficiency by 80%.

[0091] Closed-loop control and vibration reduction structures balance safety and construction quality.

[0092] Example 4: Multi-node symmetrical tower crane attachment device

[0093] Applicable scenarios: Super high-rise projects with a polygonal core section, such as a regular hexagon, and where tower cranes need to rotate 360°, such as super high-rise commercial complexes.

[0094] Structural composition

[0095] Embedded nodes: One embedded component 2 is set at the midpoint of each side of the hexagonal outer wall 11 of the core tube, for a total of 6 nodes, with an included angle of 60° between the nodes.

[0096] Wall-mounted members: 6 sets of hydraulic push rods, i.e., wall-mounted members 4, are symmetrically arranged. Each set makes an angle of 30° with the tangent direction of the tower body 6, forming a "hexagonal-circular" transition support structure.

[0097] Flange assembly: An annular flange is welded to the outside of the tower body. Flange plate 252 has a diameter of 1.2m and a thickness of 25mm. Six flange plates 151 are evenly distributed on the annular flange to ensure uniform stress distribution.

[0098] Working principle

[0099] When the tower crane is in full rotation operation, the lifting loads in different directions are transferred to the core tube through symmetrically arranged hydraulic push rods, avoiding local stress concentration.

[0100] When the polygonal cross-sectional dimensions of the core tube change, such as when the side length increases from 5m to 6m, the length of the 6 sets of hydraulic push rods is adjusted synchronously. When the length increases from 4m to 4.8m, the symmetrical support is maintained to ensure that the verticality deviation of the tower body is ≤1‰.

[0101] Each pre-embedded node is fixed by two M36 double-headed bolts in parallel to improve the node's pull-out bearing capacity, with a single node pull-out force ≥200kN.

[0102] Beneficial effects

[0103] The multi-node symmetrical arrangement adapts to polygonal cross sections, meeting the requirements for full-rotation operation.

[0104] Synchronous adjustment ensures balanced stress and avoids localized damage to the core tube.

[0105] Example 5: Eccentric Compensation Tower Crane Attachment Device

[0106] Applicable scenarios: When the core tube is severely eccentric, with an eccentricity greater than 800mm, or when the construction environment is limited, such as super high-rise projects adjacent to existing buildings.

[0107] Structural optimization compared to Example 2

[0108] Wall-mounted member arrangement: 5 sets of wall-mounted members are provided, of which 3 sets are located on the eccentric side with a spacing of 2.5m and an inclination angle of 60°, and 2 sets are located on the non-eccentric side, arranged horizontally with a spacing of 3m, forming an "eccentric support" structure.

[0109] Differentiated design of hydraulic actuators: The eccentric side hydraulic actuator is made of high-strength alloy steel 40CrNiMoA with a rated thrust of 180kN, while the non-eccentric side is made of conventional Q345 material with a rated thrust of 100kN.

[0110] Ball joint assembly reinforcement: An annular reinforcing rib with a thickness of 10mm is added to the eccentric ball joint seat 31. The ball joint 32 and the hydraulic push rod are welded with a bevel and the weld leg height is 15mm to improve the torsional strength.

[0111] Working principle

[0112] When the eccentricity of the core tube causes the tower body to tend to tilt towards the non-eccentric side, the three sets of hydraulic push rods on the eccentric side extend synchronously, such as by 80mm, generating a pulling force towards the core tube to balance the tilting moment.

[0113] The non-eccentric horizontal members help limit the horizontal displacement of the tower body, forming a "tension-compression synergy" force system.

[0114] Regularly monitor the force deviation of each group of rods using the pressure sensor of the hydraulic push rod, ensuring it is ≤5%, and adjust the length in a timely manner to avoid local overload.

[0115] Beneficial effects

[0116] Differentiated support and eccentric compensation design solve the stability problem under severe eccentric working conditions.

[0117] High-strength structure and stress monitoring ensure safety under extreme working conditions.
