Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an integrated sound insulation and earthquake-resistant partition wall structure for ultra-high-rise buildings. Background Technology

[0002] In traditional high-rise buildings, the commonly used partition wall structures are mostly block walls (such as aerated concrete blocks) or 200mm thick reinforced concrete shear walls. These structural systems have two significant problems: First, insufficient seismic performance. Block walls lack flexible connections and energy-dissipating structures, and are often rigidly connected to the main structure (such as steel bars directly anchored into beams and slabs). Under earthquake action, they cannot release energy through slippage or controllable cracks, resulting in wall cracks exceeding 0.5mm in width, making them difficult to repair after structural damage, and causing additional destructive effects on the main structure. Second, poor sound insulation. Due to their high porosity, lightweight blocks only provide about 40dB of sound insulation. Furthermore, problems such as unfilled gaps between walls and beams and slabs and improper hole treatment during construction further weaken the sound insulation performance, failing to meet the stringent sound insulation requirements of highly sensitive places such as residences, conference rooms, and equipment rooms. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated sound insulation and earthquake resistance partition wall structure for ultra-high-rise buildings. It can flexibly connect the double-layer bidirectional steel reinforcement inside the partition wall with the X-shaped steel reinforcement skeleton on the top and sides, and construct a stiffness reduction zone and a controllable crack induction zone by embedding staggered extruded polystyrene boards in segments along the horizontal direction. It utilizes the interface cracks of the extruded polystyrene board and the plastic deformation of the X-shaped steel reinforcement skeleton to form a dual energy dissipation path, so that the partition wall is destroyed first and the main structure is protected. The dual sound insulation barrier of extruded polystyrene board and high-density concrete partition wall significantly improves the sound insulation performance, and achieves synergistic optimization of earthquake resistance and sound insulation performance.

[0004] To achieve the above objectives, this utility model provides an integrated sound insulation and earthquake resistance partition wall structure for super high-rise buildings, comprising:

[0005] The partition wall between households is equipped with double-layer, bidirectional steel reinforcement.

[0006] An X-shaped steel reinforcement cage is installed at the connection between the partition wall and the main structure on its top and sides. One end of the X-shaped steel reinforcement cage is anchored in the main structure, and the other end of the X-shaped steel reinforcement cage is welded to the steel reinforcement in the partition wall.

[0007] Multiple sets of extruded polystyrene (XPS) boards are embedded in the partition wall at intervals along the horizontal direction. Each set of XPS boards includes two XPS boards that are staggered and embedded on both sides of the partition wall.

[0008] Optionally, the partition wall is a reinforced concrete wall, and the overall thickness of the partition wall is 130mm-170mm.

[0009] Optionally, the thickness of the thinnest part of the partition wall after the extruded polystyrene board is embedded shall not be less than 100mm.

[0010] Optionally, the extruded polystyrene board is provided in three sets, respectively located at both ends of the partition wall and in the center, and all three sets of the extruded polystyrene board are located at the top of the partition wall.

[0011] Optionally, a horizontal displacement gap of 25mm-35mm is reserved between the partition wall and the main structure.

[0012] Optionally, the X-shaped steel reinforcement cage is provided with a reinforcing member at the intersection, which is a metal reinforcing plate or steel sleeve covering or sleeved on the outside of the intersection.

[0013] Optionally, the steel reinforcement includes vertical main bars and horizontal main bars.

[0014] The beneficial effects of this utility model are as follows: By setting double-layer bidirectional steel reinforcement inside the partition wall and setting an X-shaped steel skeleton between the partition wall and the main structure on the top and sides to achieve flexible connection; at the same time, multiple sets of staggered extruded polystyrene boards are embedded in sections along the horizontal direction to form a stiffness weakening zone and a controllable crack induction zone. During an earthquake, energy can be released through the cracks at the interface of the extruded polystyrene board, and the plastic deformation of the X-shaped steel skeleton can cause horizontal displacement between the partition wall and the main structure, forming a dual energy dissipation path. This makes the partition wall the priority failure unit, avoiding damage to the main structure, thereby significantly improving the overall seismic performance of the building; in addition, the double sound barrier formed by the extruded polystyrene board and the high-density concrete partition wall can effectively improve the sound insulation of the wall, meet the sound insulation requirements of highly sensitive places, and achieve synergistic optimization of seismic resistance and sound insulation performance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see Figure 1 and Figure 2 A preferred embodiment of this application shows an integrated sound insulation and seismic resistance partition wall structure for a high-rise building, comprising a partition wall 1, an X-shaped steel reinforcement frame 2, and extruded polystyrene (XPS) boards 3. The partition wall 1 is equipped with double-layered, bidirectional steel reinforcement 4. The X-shaped steel reinforcement frame 2 is located at the connection points between the partition wall 1 and the main structure 5 on its top and sides. One end of the X-shaped steel reinforcement frame 2 is anchored within the main structure 5, and the other end is welded to the steel reinforcement 4 within the partition wall 1. Multiple sets of XPS boards 3 are horizontally spaced within the partition wall 1, with each set comprising two XPS boards 3 staggered and embedded on both sides of the partition wall 1.

[0023] According to the embodiment of this utility model, double-layer bidirectional steel reinforcement 4 is installed inside the partition wall 1, and an X-shaped steel skeleton 2 is installed between the partition wall 1 and the main structure 5 on the top and sides to achieve flexible connection. At the same time, multiple sets of staggered extruded polystyrene boards 3 are embedded in segments along the horizontal direction to form a stiffness weakening area and a controllable crack induction area. During an earthquake, energy can be released through the interface cracks of the extruded polystyrene board 3, and horizontal displacement can be generated between the partition wall 1 and the main structure 5 through the plastic deformation of the X-shaped steel skeleton 2, forming a dual energy dissipation path. This makes the partition wall 1 the priority failure unit, avoiding damage to the main structure 5, thereby significantly improving the overall seismic performance of the building. In addition, the double sound barrier formed by the extruded polystyrene board 3 and the high-density concrete partition wall 1 can effectively improve the sound insulation of the wall to more than 50dB, meeting the sound insulation requirements for highly sensitive places in GB55038-2025 "Residential Project Code", achieving synergistic optimization of seismic resistance and sound insulation performance. It is particularly suitable for super high-rise residential buildings and commercial complexes with seismic fortification intensity ≤8 degrees.

[0024] The following detailed description uses specific examples:

[0025] Please see Figure 1 and Figure 2 The partition wall 1 is a reinforced concrete wall with an overall thickness of 130mm-170mm. After embedding extruded polystyrene (XPS) boards 3, the thinnest part of the partition wall 1 is no less than 100mm. Compared to the traditional 200mm thick wall design, the thickness design of the partition wall 1 significantly reduces its weight and improves construction efficiency. Simultaneously, multiple sets of staggered XPS boards 3 are embedded in segments within the partition wall 1, ensuring that the thinnest part of the partition wall 1 after embedding the XPS boards 3 is no less than 100mm. While actively weakening the stiffness of the partition wall 1 to 530%-40% of the main structure, it still maintains necessary structural stiffness and stability, forming a "weakened energy dissipation zone." This effectively releases seismic energy, ensures the safety and crack control of the partition wall 1 under non-seismic conditions, and improves overall sound insulation performance. Specifically, in this embodiment, the overall thickness of the partition wall 1 is 150mm.

[0026] Specifically, in this embodiment, the extruded polystyrene board 3 is an XPS extruded polystyrene board with a cross-sectional size of 40×40mm. Three sets are arranged, one at each of the two ends and the other centrally located inside the partition wall 1. All three sets of extruded polystyrene boards 3 are located at the top of the partition wall 1. This arrangement forms a continuous crack guiding zone and a stress buffer zone, making the crack distribution in the partition wall 1 more uniform and controllable during vibration, effectively delaying and weakening the propagation of damage, and improving the gradual nature of earthquake resistance and the residual bearing capacity of the partition wall 1 after failure.

[0027] A horizontal displacement gap of 25mm-35mm is reserved between the partition wall 1 and the main structure 5. Under seismic loading, the partition wall 1 can allow the weakest part to displace preferentially through this gap; when the displacement exceeds the limit, the X-shaped steel reinforcement skeleton at the top and sides enters the plastic deformation stage, causing the partition wall 1 to fail before the main structure 5, thereby effectively releasing seismic energy, ensuring the safety of the main structure 5, and improving the overall seismic performance of the building. In this embodiment, the horizontal displacement gap is 30mm.

[0028] Furthermore, the X-shaped steel reinforcement cage is equipped with reinforcing members at the intersections. These reinforcing members are metal reinforcing plates or steel sleeves that cover or cover the outside of the intersections. The reinforcing members are securely connected to the X-shaped steel reinforcement cage by welding, bolting, or snap-fit ​​fixing to enhance the structural stability of the intersections, prevent misalignment or loosening of the X-shaped steel reinforcement cage, and thus improve the overall robustness and seismic reliability of the X-shaped steel reinforcement cage.

[0029] Specifically, the steel reinforcement 4 includes vertical main bars 41 and horizontal main bars 42. The Φ10×250mm vertical main bars 41 and the Φ6×200mm horizontal main bars 42 form a double-layer, two-way reinforcement skeleton, which not only enhances the load-bearing capacity of the partition wall 1 in the vertical and horizontal directions, but also ensures crack control under multi-point stress conditions. At the same time, it facilitates the welding connection of the X-shaped steel reinforcement skeleton 2, providing a good structural skeleton support for the partition wall 1.

[0030] The construction of the partition wall structure includes the following steps: First, positioning and layout are carried out to determine the position of the wall according to the drawings; second, the steel reinforcement is tied, during which three sets of XPS extruded polystyrene boards 3 with a size of 40×40mm are pre-embedded in sections (including the two ends and the central area of ​​the partition wall 1). The extruded polystyrene board 3 adopts a groove design to induce crack interfaces; in areas with embedded parts or pipelines, grooves can be left in the extruded polystyrene board 3; after the steel reinforcement is tied, the formwork is sealed, and the partition wall 1 is poured with C35 concrete as a whole. After the formwork is removed, curing is carried out.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
