Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a layered anchored composite exterior wall structure. Background Technology

[0002] While the widely used pure reinforced concrete walls have high structural strength, their heavy weight and high thermal conductivity make them difficult to meet the thermal insulation requirements of modern buildings and increase structural load. On the other hand, pure block walls are lightweight and easy to construct, but they have poor waterproof performance, insufficient crack resistance, and are prone to leakage problems after long-term use.

[0003] In exterior wall applications, walls need to fulfill multiple functions, including space partitioning, waterproofing, sound insulation, and heat insulation. A single material cannot achieve a balance of these requirements. Furthermore, in traditional construction processes, the joints between dissimilar materials are often weak points, resulting in insufficient overall wall integrity. Especially with the demands of waterproofing, heat insulation, and sound insulation, the comprehensive performance of traditional walls falls far short of the requirements of modern architecture. Utility Model Content

[0004] The purpose of this utility model is to provide a layered anchored composite exterior wall structure that can form a double-layered partition wall by combining concrete walls and masonry walls, effectively solving the problems of strong water absorption and easy leakage of traditional masonry walls and the heavy weight of pure concrete walls.

[0005] To achieve the above objectives, this utility model provides a layered anchored composite exterior wall structure, comprising: The partition wall consists of an outer concrete wall and an inner masonry wall, with tie bars for connection and fixation between the concrete wall and the masonry wall. Structural columns are embedded at intervals within the partition walls; The vertical reinforcement bars of the wall panel are spaced out within the concrete wall, and the two ends of the vertical reinforcement bars of the wall panel are not anchored to the main structure. The horizontal reinforcement of the wall panel includes a first horizontal reinforcement anchored at both ends into the main structure or structural column and set in the concrete wall and the masonry wall, and a second horizontal reinforcement not anchored at both ends into the main structure or structural column and set in the concrete wall. The first horizontal reinforcement and the second horizontal reinforcement are set vertically at intervals in the partition wall.

[0006] Optionally, the vertical reinforcement bars of the wall panel are set as follows: When both sides of the partition wall are structural columns or shear walls, the two ends of the vertical reinforcement bars of the wall panel are not anchored to the main structure. When one side of the partition wall is a structural column or shear wall, the two ends of the vertical reinforcement bars of the wall panel are anchored to the main structure.

[0007] Optionally, the thickness of both concrete walls and masonry walls is 80mm-120mm.

[0008] Optionally, the vertical spacing between two adjacent first horizontal reinforcing bars is 550mm-650mm.

[0009] Optionally, the horizontal spacing between two adjacent structural columns is 3.5m-4.5m.

[0010] Optionally, the structural column is provided with vertical steel bars anchored into the main structure at both ends and stirrups spaced at intervals along the vertical direction.

[0011] The beneficial effects of this utility model are as follows: by combining concrete walls and block walls to form a double-layer partition wall, the problems of strong water absorption, easy leakage, and heavy self-weight of traditional block walls are effectively solved; the outer waterproof concrete wall can effectively block external moisture penetration and improve the waterproof performance of the wall; by completely separating the upper and lower ends of the block wall from the main structure and connecting them only through tie bars embedded in the concrete wall, the block wall does not participate in the force transmission, thereby completely isolating the load of the main structure, improving the stability of the wall, and avoiding the stress concentration and cracking problems that may be caused by traditional rigid connections. At the same time, by replacing half of the traditional concrete wall with a block wall, the self-weight of the wall can be greatly reduced.

[0012] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. 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.

[0017] Please see Figure 1 and Figure 2 A preferred embodiment of this application shows a layered anchored composite exterior wall structure including a partition wall 1, structural columns 2, vertical reinforcing bars 13 and horizontal reinforcing bars 14. The partition wall 1 includes an outer concrete wall 11 and an inner masonry wall 12, with tie bars 15 for connection and fixation between the concrete wall 11 and the masonry wall 12. The structural columns 2 are embedded in the partition wall 1 at intervals. The vertical reinforcing bars 13 are spaced apart in the concrete wall 11, and the two ends of the vertical reinforcing bars 13 are not anchored to the main structure 3. The horizontal reinforcing bars 14 include a first horizontal reinforcing bar 141 anchored at both ends into the main structure 3 or the structural columns 2 and disposed in the concrete wall 11 and the masonry wall 12, and a second horizontal reinforcing bar 142 not anchored at both ends into the main structure 3 or the structural columns 2 and disposed in the concrete wall 11. The first horizontal reinforcing bars 141 and the second horizontal reinforcing bars 142 are spaced apart vertically in the partition wall 1.

[0018] According to the embodiment of this utility model, by combining concrete wall 11 and block wall 12 to form a double-layer partition wall 1, the problems of strong water absorption and easy leakage of traditional block wall 12 and heavy self-weight of pure concrete wall 11 are effectively solved. The outer waterproof concrete wall 11 can effectively block external water penetration and improve the waterproof performance of the wall. By completely separating the upper and lower ends of the block wall 12 from the main structure 3 and connecting them only through the tie bars 15 pre-embedded in the concrete wall 11, the block wall 12 does not participate in the force transmission, thereby completely isolating the load of the main structure 3, improving the stability of the wall, and avoiding the stress concentration and cracking problems that may be caused by traditional rigid connection. At the same time, by replacing half of the traditional concrete wall with block wall 12, the self-weight of the wall can be greatly reduced.

[0019] The following detailed description uses specific examples: Furthermore, the vertical reinforcement 13 of the wall panel is configured such that: when both sides of the partition wall 1 are structural columns 2 or shear walls, the two ends of the vertical reinforcement 13 are not anchored to the main structure 3; when one side of the partition wall 1 is a structural column 2 or shear wall, the two ends of the vertical reinforcement 13 are anchored to the main structure 3. This configuration can adapt to different structural forms and, while ensuring structural stability, avoids excessive rigid connections, reducing the risk of cracking due to stress concentration.

[0020] Specifically, the thickness of both the concrete wall 11 and the masonry wall 12 is 80mm-120mm. In this embodiment, the thickness of both the concrete wall 11 and the masonry wall 12 is 100mm. This thickness setting ensures that the wall has sufficient strength while avoiding the problem of excessive weight due to excessive thickness, further optimizing the waterproof, heat insulation, and sound insulation effects of the wall.

[0021] Specifically, the vertical spacing between two adjacent first horizontal reinforcing bars 141 is 550mm-650mm. In this embodiment, the vertical spacing between two adjacent first horizontal reinforcing bars 141 is 600mm. This arrangement can reasonably distribute the horizontal reinforcing bars in the wall, ensuring that the reinforcing bars can evenly bear the stress of the wall, improving the overall stability and crack resistance of the wall, and avoiding potential risks caused by uneven distribution of reinforcing bars.

[0022] Specifically, the horizontal spacing between two adjacent structural columns 2 is 3.5m-4.5m. In this embodiment, the horizontal spacing between two adjacent structural columns 2 is 4m. This arrangement ensures the stability of the wall and, through the design of structural columns 2 with reasonable spacing, enhances the seismic resistance and durability of the wall, avoiding material waste caused by excessively dense structural columns 2.

[0023] Please see Figure 3The structural column 2 is equipped with vertical steel bars 21 anchored at both ends into the main structure 3, as well as stirrups 22 spaced vertically. This design can enhance the structural performance of the structural column 2, improve the seismic resistance and stability of the wall, and avoid the instability of the wall caused by insufficient structural columns 2.

[0024] During the construction of this composite exterior wall, the first step is construction preparation, including cleaning the ground and accurately positioning and laying out the lines according to the drawings. Next, the reinforced concrete wall on one side is constructed first, with reinforcing bars to be pre-installed in layers within the concrete wall 11 to prepare for the subsequent construction of the masonry wall. If window openings or other openings are required, they can be pre-installed during construction to avoid later excavation. Finally, the masonry wall 12 is constructed and connected to the concrete wall 11 via pre-embedded tie bars 15 to ensure the overall stability and impermeability of the wall.

[0025] 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.

[0026] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but 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.
