Description

A prevent reinforced structure that overturns for inclined wall construction

Technical Field

The utility model belongs to the technical field of building construction, and particularly relates to an anti-overturning reinforcing structure for inclined wall construction.

Background

As shown in fig. 1, in the construction process of the super high-rise building, the core tube structure plays a crucial role in the stability of the whole building. The core barrel typically contains an elevator hoistway, a stairway hoistway, an equipment plumbing hoistway, etc., and is the "spine" of the building. In super high-rise buildings, the core tube not only bears vertical load, but also needs to share and resist horizontal load such as wind load and earthquake load. Therefore, the design and construction quality of the core tube directly affects the safety and durability of the building.

When the core tube reaches a certain height, the construction of the inclined wall becomes particularly critical. The inclined wall design is widely applied in the core tube, and the main purpose is to share part of vertical load and horizontal load through an inclined structural form, so that the overall rigidity and lateral force resistance of the building are enhanced. However, the inclined wall faces a series of special challenges in the construction stage, especially when the inclination angle of the wall is large, the difficulty and risk of construction are significantly increased.

In the construction process of the inclined wall, the initial steel bar binding and the later concrete pouring are two key stages. In the reinforcement stage, the reinforcement cage is easy to lose stability due to the inclination of the wall body, and the risk of overturning or deformation is generated. This risk not only affects the accuracy and efficiency of the reinforcement, but also may lead to deviations in the position of the reinforcement, and thus affects the quality of the concrete casting and the overall performance of the structure.

In the concrete pouring stage, the inclined angle of the inclined wall enables the gravity of the concrete to act on the inclined surface to generate horizontal component force, and the risk of wall overturning is increased. In the pouring process, the fluidity and the weight of the concrete can generate larger lateral pressure on the inclined wall structure. Without effective support and reinforcement, the tilt wall is prone to toppling or shifting before the concrete is not fully set. This not only can cause delays in construction progress, but also can present serious safety hazards, such as casualties and equipment damage.

In the prior art, construction strengthening measures for the straight wall are relatively mature, such as a scaffold support system, a template support system and the like. However, these conventional reinforcement methods are not entirely suitable for construction of the inclined wall. The specificity of the tilt wall is its angled geometry, making it difficult for conventional vertical support and reinforcement methods to provide effective support and stability. In order to prevent the inclined wall from overturning during the construction process, a specially designed reinforcing structure is required, and can provide enough supporting force and anti-overturning capability on the inclined wall body.

In addition, as the building height increases, the construction environment of the core tube becomes more complex and severe. Factors such as high-altitude operation, wind influence, temperature change and the like all bring additional challenges to the construction of the inclined wall. These external environmental factors require the reinforcement structure to have not only sufficient strength and stability, but also a certain flexibility and adaptability to cope with various unpredictable construction environment changes.

In summary, in the construction process of the inclined wall of the super high-rise building core tube, due to the inclination of the wall body and the specificity of the high-altitude operation, the existing reinforcement measures are difficult to completely meet the construction requirements. The method not only increases the overturning risk of the inclined wall in the initial reinforcing steel bar binding and later concrete pouring processes, but also forms a serious threat to the construction progress and safety. Therefore, a reinforced structure specially aiming at the construction of the inclined wall is needed, multi-level stability guarantee can be provided, the inclined wall is effectively supported and fixed, and the safety and quality of the construction process are ensured. The method is a technical problem to be solved in the prior art in the construction of the core tube inclined wall of the super high-rise building.
