[0049] Embodiment 1

[0050] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in one embodiment, a cast-in-situ window lower wall formwork structure, supported outside the outer side surface of the window hole 5 of the window lower wall 1, is used to form a V-shaped expansion joint at the window hole 5 of the window lower wall 1, comprising a formwork 2 and an expansion groove reserved assembly 3 installed on the side of the formwork 2 close to the window lower wall 1, the expansion groove reserved assembly 3 is a V-shaped structure, used to form a V-shaped expansion joint on the surface of the window hole 5 of the window lower wall 1 during pouring.

[0051] It should be noted that in order to facilitate the construction of the V-shaped expansion joint on the outer surface of the window lower wall 1, the expansion groove reserved assembly 3 is designed to be welded or mechanically installed on the side of the formwork 2 close to the window lower wall 1, and V-shaped steel can be used to make the expansion groove reserved assembly 3 during on-site construction, and wing plates are welded on both sides of the opening of the V-shaped steel, and the expansion groove reserved assembly 3 is connected with the formwork 2 by using the wing plates during use.

[0052] As Figure 4 shown is a structural diagram of the expansion groove reserved assembly 3, in specific use, the formwork 2 preferably uses an aluminum formwork with small deformation.

[0053] In use, first, according to the design width and depth of the deformation joint, the stretch groove reservation assembly 3 of corresponding depth or width is welded or mechanically connected on the surface of the template 2, then the template 2 is supported on the inner and outer surfaces of the under-window wall 1, so that the stretch groove reservation assembly 3 faces the concrete side, after pouring, a once-formed V-shaped stretch joint is left on the concrete surface of the under-window wall, and the pulling joint 6 is obtained under the window hole 5, so that the working efficiency of workers is effectively improved, and the reservation accuracy of the stretch joint is ensured.
