Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and particularly relates to an anti-overturning reinforcement structure for inclined wall construction. Background Technique
[0002] As Figure 1 shown, during the construction of super high-rise buildings, the core tube structure plays a crucial role in the stability of the overall building. The core tube usually includes elevator shafts, stairwells, equipment pipe shafts, etc., and is the "spine" of the building. In super high-rise buildings, the core tube not only bears vertical loads but also needs to share and resist horizontal loads such as wind loads and seismic loads. Therefore, the design and construction quality of the core tube directly affect the safety and durability of the building.
[0003] When the core tube reaches a certain height, the construction of the inclined wall becomes particularly critical. The inclined wall design is widely used in the core tube, mainly aiming to share part of the vertical load and horizontal load through the inclined structural form, enhancing the overall stiffness and lateral force resistance performance of the building. However, the inclined wall faces a series of special challenges during the construction stage, especially when the wall inclination angle is relatively large, the construction difficulty and risk increase significantly.
[0004] During the construction process of the inclined wall, the initial steel bar binding and the later concrete pouring are two key stages. During the steel bar binding stage, due to the inclination of the wall, the steel bar skeleton is prone to losing stability, with the risk of overturning or deformation. This risk not only affects the accuracy and efficiency of steel bar binding but may also lead to the deviation of the steel bar position, thus affecting the quality of concrete pouring and the overall performance of the structure.
[0005] During the concrete pouring stage, the inclined angle of the inclined wall causes the gravity of the concrete to generate a horizontal component force on the inclined surface, increasing the risk of wall overturning. During the pouring process, the fluidity and weight of the concrete will generate a large lateral pressure on the inclined wall structure. Without effective support and reinforcement measures, the inclined wall is very likely to overturn or shift before the concrete is completely solidified. This will not only cause delays in the construction progress but may also bring serious safety hazards such as casualties and equipment damage.
[0006] In the prior art, the construction reinforcement measures for straight walls are relatively mature, such as scaffolding support systems, formwork support systems, etc. However, these traditional reinforcement methods are not entirely applicable to the construction of inclined walls. The particularity of the inclined wall lies in its inclined geometric shape, making it difficult for traditional vertical support and reinforcement methods to provide effective support and stability. In order to prevent the inclined wall from overturning during construction, a specially designed reinforcement structure is required, which can provide sufficient support force and anti-overturning ability on the inclined wall.
[0007] In addition, as the building height increases, the construction environment of the core tube becomes more complex and harsh. Factors such as high-altitude operations, wind impact, and temperature changes will bring additional challenges to the construction of inclined walls. These external environmental factors require that the reinforced structure not only have sufficient strength and stability, but also have a certain degree of flexibility and adaptability to cope with various unforeseen changes in the construction environment.
[0008] In summary, during the construction of the inclined wall of the core tube of a super high-rise building, due to the inclination of the wall and the particularity of high-altitude operations, the existing reinforcement measures are difficult to fully meet the construction needs. This not only increases the risk of overturning of the inclined wall during the initial reinforcement binding and later concrete pouring, but also poses a serious threat to the construction progress and safety. Therefore, there is an urgent need for a reinforcement structure specifically for the construction of inclined walls that can provide multi-level stability guarantees, effectively support and fix the inclined walls, and ensure the safety and quality of the construction process. This is a technical problem that needs to be solved in the construction of the inclined wall of the core tube of a super high-rise building. Utility Model Content

[0015] By combining the internal reinforcement structure and the external reinforcement structure, multi-level stability guarantee is achieved. The internal reinforcement structure utilizes the combination of anchor bolts, head plates, and steel H-beams to effectively support and fix the inclined wall, while the external reinforcement structure provides additional anti-overturning support through diagonal braces.

[0027] Among them, the steel section bars 21 are I-beams. The I-beams are selected in 16# or 18# specifications that meet the national standards to ensure sufficient load-bearing capacity.
[0028] The steel section bars 21 are arranged at intervals of 1.4 to 1.5 m. The specific spacing is optimized according to the load condition of the inclined wall, and preferably 1.5 m.

Existing technologies are difficult to meet the reinforcement requirements of such inclined structures. Especially during the initial steel bar binding and the later concrete pouring process, the inclined walls are prone to overturning, bringing construction safety hazards and quality problems.
