Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a prefabricated, formwork-free, all-concrete anti-seismic wall structure. Background Technology

[0002] In the construction field, the construction of all-concrete shear wall structures has always been a critical step, as its performance directly affects the safety and durability of buildings. However, traditional shear wall construction methods still have the following problems: Traditional cast-in-place concrete shear walls require on-site formwork erection, concrete pouring, and formwork removal only after the concrete has reached its strength. This method is cumbersome, has low formwork turnover efficiency, and the removal process easily leads to material waste and wall surface damage. Furthermore, existing wall structures are of a single composition, resulting in insufficient structural load-bearing capacity, lateral force resistance, and robustness.

[0003] To address the aforementioned issues, this utility model document proposes a prefabricated, formwork-free, all-concrete anti-seismic wall structure. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as cumbersome concrete casting process, low formwork turnover efficiency, and simple structural composition, and to propose a prefabricated, formwork-free, all-concrete structure for anti-seismic walls.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A prefabricated, formwork-free, all-concrete shear wall structure includes: Shear walls and concrete infill walls are provided, and the shear walls and concrete infill walls can be arranged sequentially and at intervals as needed. The top of the shear walls and concrete infill walls is provided with the same top beam to complete the composition of the building wall structure. It also includes multiple sets of non-removable template units, which are used to complete the composition of the wall structure.

[0006] In one possible design, the shear wall consists of two sets of removable formwork units, with a steel frame structure inside and filled with poured concrete.

[0007] In one possible design, the concrete infill wall also consists of two sets of formwork units that do not require removal, with concrete directly poured inside.

[0008] In one possible design, an elastic material is fixedly installed between the shear wall and the adjacent concrete infill wall.

[0009] In one possible design, the steel frame structure includes a plurality of first reinforcing bars and a plurality of second reinforcing bars, the plurality of first reinforcing bars being vertically fixed to the foundation, and the plurality of second reinforcing bars being horizontally arranged on both sides of the plurality of first reinforcing bars and tied and fixed to adjacent first reinforcing bars to form a frame.

[0010] In one possible design, the removable formwork unit is a prefabricated reinforced concrete formwork.

[0011] In this application, during construction, shear walls and concrete infill walls can be set up individually or sequentially at intervals according to actual needs, and the two adjacent walls are connected by elastic materials.

[0012] When constructing a shear wall, multiple first reinforcing bars are first vertically fixed to the foundation in pairs, and multiple sets of second reinforcing bars are arranged on both sides, evenly distributed from bottom to top. The first and second reinforcing bars are then tied together to form a stable support frame.

[0013] When constructing shear walls and infill walls, the wall frame is formed by the cooperation of two side-by-side formwork units that do not require removal. After all formwork is installed and connected, concrete is poured into the casting cavity. The concrete fills the gaps between the formwork units and covers the corresponding supporting frame, forming a continuous, integral wall. Once the concrete has hardened, the formwork units do not need to be dismantled and can be embedded into the wall, eliminating the need for formwork removal. Furthermore, depending on the actual situation and requirements, they can also be used directly as a wall finishing layer, eliminating the need for plastering and significantly improving construction quality and efficiency.

[0014] Beneficial effects: In this utility model, the prefabricated formwork-free anti-shear wall is a full concrete structure. The wall structure is a shear wall structure for load bearing and lateral force resistance, and the infill wall is a concrete infill wall. At the same time, by using formwork-free units, the formwork removal process in traditional construction is eliminated, the construction process is simplified, the construction efficiency is significantly improved, and the damage that may be caused to the wall structure during the formwork removal process is avoided. In this utility model, the prefabricated, formwork-free, all-concrete shear wall structure has a support frame in the shear wall formed by binding and fixing the first and second reinforcing bars. The structure is stable, and the reinforcing bars have a good synergistic force-bearing effect, which greatly improves the seismic performance of the wall. The infill wall is directly filled with concrete, which can ensure that the wall has good strength and load-bearing capacity. In this utility model, the structure uses two types of wall panels to be spliced ​​together, and with the addition of a non-removable formwork, the demolding process can be eliminated, improving efficiency and avoiding damage to the wall structure. The combination of the steel frame and the dense concrete wall improves the overall structural stability, enhances the earthquake resistance and load-bearing capacity of the building, simplifies the assembly process, and ensures that the wall is not easily damaged during construction and has a long service life.

The top of the shear wall 19 and the concrete infill wall 20 are provided with the same top beam 23 to complete the composition of the house wall structure. In this embodiment, the two sides of the non-removable template unit 4 are combined to form a wall, and a casting cavity is formed between the two sides of the non-removable template unit 4. In this embodiment, the shear wall 19 is composed of two sets of template-free units 4, which are equipped with steel frame structure 22 and filled with concrete. The concrete infill wall 20 is also composed of two sets of template-free units 4, which are directly filled with concrete. The steel frame structure 22 includes multiple first reinforcing bars and multiple second reinforcing bars. The first reinforcing bars are vertically fixed to the foundation, and the second reinforcing bars are horizontally arranged on both sides of the first reinforcing bars. The multiple first reinforcing bars and multiple second reinforcing bars are fixed together by binding with steel wires, thereby forming a stable support frame, providing basic support for the subsequent construction of the shear wall 19.

[0024] When installing shear wall 19, multiple first reinforcing bars are first vertically fixed to the foundation in pairs, and multiple sets of second reinforcing bars are arranged on both sides, with the second reinforcing bars evenly distributed from bottom to top. Then, the first and second reinforcing bars are tied together to form a stable support frame.

[0025] During the installation of shear wall 19 and infill wall 20, the wall frame is formed by the cooperation of the two side-by-side non-removable formwork units 4. After all the formwork is installed and connected, concrete is poured into the casting cavity. The concrete fills the gaps between the formwork and covers the corresponding supporting frame, forming a continuous integral wall. After the concrete hardens, the non-removable formwork units 4 do not need to be disassembled and can be embedded into the wall, eliminating the corresponding formwork removal steps. At the same time, depending on the actual situation and corresponding needs, they can also be directly used as the wall finishing layer, eliminating the need for wall plastering and significantly improving construction quality and efficiency.
