Description

Technical Field

[0001] The utility model relates to the technical field of shear wall structures, in particular to a T-shaped shear wall formwork for modular buildings. Background Art

[0002] Prefabricated shear walls are a new type of shear wall that is manufactured in a factory using advanced processes and technologies, then transported to the site for installation. Compared to traditional cast-in-place concrete shear walls, prefabricated shear walls offer advantages such as shorter manufacturing cycles, controlled quality, faster construction, and energy conservation and environmental protection.

[0003] Existing prefabricated shear walls used in concrete modular buildings typically utilize prefabricated wall forms integrated into concrete modules as formwork for pouring concrete. These forms suffer from the following disadvantages: 1. The shear wall reinforcement requires extensive on-site tying, limiting production efficiency; 2. The prefabricated wall formwork serves only as a formwork and does not participate in the structural stress of the shear wall, resulting in a waste of material and making the shear wall thicker, encroaching on the usable indoor area.

[0004] The prefabricated shear walls used in concrete modular buildings include T-shaped shear walls, which are set at the connection between adjacent modular buildings and serve as structural supports to connect adjacent modular buildings to ensure that the connection between modules has sufficient stability and safety under the action of external forces.

[0005] For this reason, there is an urgent need for an improved T-shaped shear wall formwork for modular buildings. Utility Model Content

[0044] Example 1

[0045] like Figures 1 to 7 As shown, this embodiment provides a T-shaped shear wall formwork for modular buildings. The T-shaped shear wall formwork is described in detail below.

[0046] like Figure 1 As shown, the T-shaped shear wall formwork includes a first formwork 11 and a second formwork 21 arranged opposite to each other. The first formwork 11 and the second formwork 21 are respectively located on two adjacent modular buildings, and a flat cavity is formed between the first formwork 11 and the second formwork 21. The flat cavity contains a steel cage, which includes a steel bar group and an internal steel bar group for connecting two adjacent steel bar groups. The steel bar group refers to a cage-shaped structure made of steel bars used to construct edge hidden columns, edge end columns, and edge corner walls in a concrete structure.

[0047] The reinforcement group includes a first reinforcement group 14 and a second reinforcement group 15. The internal reinforcement group includes a truss 12, and a first reinforcement mesh 13 and a second reinforcement mesh 23 arranged in sequence along the direction from the first formwork 11 to the second formwork 21. The truss 12 extends along the height of the shear wall and has a first end and a second end opposite each other in the direction from the first formwork 11 to the second formwork 21. The first reinforcement group 14 is fixedly mounted at the first end of the first formwork 11, and the second reinforcement group 15 is fixedly mounted at the second end of the first formwork 11. The first reinforcement mesh 13 is fixedly connected to the first reinforcement group 14 and the second reinforcement group 15, respectively.

The first end of the truss 12 is fixedly connected to the first reinforcement mesh 13, and the first end of the truss 12 is embedded in the first formwork 11, so that the first reinforcement mesh 13 is laid flat on the first formwork 11, forming a first prefabricated component. The second formwork 21 itself forms a second prefabricated component.

[0048] The T-shaped shear wall formwork set up above is suitable for automated binding or welding of the steel bars in the internal structure, thereby improving production efficiency. By pre-embedding the internal structure in the first formwork 11 to form a first prefabricated component, the steel bar connection of the internal structure is generated in the wall formwork prefabrication link, which greatly reduces the amount of steel bar binding and welding in on-site construction, thereby greatly improving production efficiency.

In addition, since the first steel bar group 14, the second steel bar group 15 and the internal structure are pre-embedded in the first formwork 11, the inner surface of the second formwork 12 is smooth and free of pre-embedded steel bars. During construction, when the T-shaped shear wall formwork is assembled according to the prefabricated components, there is no problem of collision and obstruction of assembly between the steel bars on the first formwork 11 and the steel bars on the second formwork 12, thereby improving construction efficiency.
