[0028] like Figure 2 As shown, the width of the second cover plate 4 in this embodiment is not greater than 1 / 2 of the width of the first cover plate 3 .

[0029] like Figure 1 and Figure 2 As shown, the top of the window sill cover in this embodiment is provided with a first wooden square 6 arranged transversely, and the first wooden square 6 is flush with the top of the inner bottom template 1 of the window sill and the top of the outer bottom template 2 of the window sill;

[0030] The outer side of the window sill inner bottom template 1 and the outer side of the window sill outer bottom template 2 are both provided with a vertically arranged second wooden square 7, and the bottom tensioning assembly 5 tightens and fixes the window sill inner bottom template 1, the window sill outer bottom template 2 and the second wooden square 7.

[0031] like Figure 1 and Figure 2 As shown, the bottom tensioning assembly 5 of this embodiment includes bottom tensioning bolts. The bottom tensioning bolts tighten and secure the formwork assembly through tensioning tubes 17. The bottom tensioning bolts, in conjunction with the tensioning tubes, along with mountain clamps and nuts, secure the inner and outer formwork of the exterior window wall.

[0032] like Figure 1 and Figure 2 As shown, an external window wall anti-seepage template structure of this embodiment further includes a window sill inner top template 8, a window sill outer top template 9 and a top tensioning assembly 11. The window sill inner top template 8 and the window sill outer top template 9 are arranged parallel to each other. A supporting template 10 is provided between the bottom of the window sill inner top template 8 and the bottom of the window sill outer top template 9. The window sill inner top template 8 and the window sill outer top template 9 are tightened and fixed by the top tensioning assembly 11.

[0033] A supporting structure is provided between the windowsill inner top template 8, the windowsill outer top template 9 and the windowsill inner bottom template 1, the windowsill outer bottom template 2.

[0034] like Figure 1 and Figure 2As shown, the support structure of this embodiment includes an oil tray 14 and supporting steel pipes 19. The oil tray 14 is vertically arranged between the window sill inner top formwork 8, the window sill outer top formwork 9, and the window sill inner bottom formwork 1, and the window sill outer bottom formwork 2. Two supporting steel pipes 19 are installed in the upper tray of the oil tray 14, and two supporting steel pipes 19 are installed in the lower tray of the oil tray 14. The supporting steel pipes 19 are arranged horizontally and perpendicular to the window sill inner top formwork 8, the window sill outer top formwork 9, the window sill inner bottom formwork 1, and the window sill outer bottom formwork 2. The oil tray is used in conjunction with the supporting steel pipes to effectively support the window sill bottom formwork and the window sill upper formwork, providing stable and effective support.

[0035] like Figure 2 As shown, a transversely arranged third wooden square 12 is provided below the supporting formwork 10 of this embodiment, and the third wooden square 12 is flush with the bottom of the top formwork 8 on the inner side of the windowsill and the bottom of the top formwork 9 on the outer side of the windowsill.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the outer side of the inner top template 8 of the windowsill and the outer side of the outer top template 9 of the windowsill are both provided with a vertically arranged fourth wooden square 13, and the top tensioning assembly 11 tightens and fixes the inner top template 8 of the windowsill, the outer top template 9 of the windowsill and the fourth wooden square 13.

[0037] Specifically, the top tensioning assembly 11 includes top tensioning bolts. The top tensioning bolts tighten and secure the formwork assembly through tensioning tubes 17. The top tensioning bolts, in conjunction with the tensioning tubes, are used in conjunction with mountain clamps and nuts to secure the inner and outer formwork of the exterior window wall.

[0038] In this embodiment, an anti-leakage groove 16 is formed on the outer side of the outer window wall 15 , and a water retaining platform 18 is formed on the inner side of the outer window wall 15 .

[0039] In this embodiment, the wooden planks serve as secondary keels during the formwork reinforcement process, while the formwork serves as the side formwork for the wall and the cover for the window sill. The supporting steel pipes serve as the primary keel and vertical rods. The supporting steel pipes, when used in conjunction with the oil support, can adjust the height of the oil support to suit different construction requirements.

[0040] In this embodiment, the first cover plate 3 and the second cover plate 4 are nailed together, with the first cover plate 3 superimposed on the upper surface of the second cover plate 4. This forms a stepped structure, i.e., a tongue-and-groove structure, which serves as a cover plate during the window formwork reinforcement process. After the concrete is poured, the window sill forms a water retaining platform 18, which is higher inside and lower outside, to prevent leakage from the window.

[0041] During the construction of the anti-seepage formwork structure of the exterior window wall of this embodiment, the construction layout is carried out according to the design drawings, and the formwork of the window opening is matched. The opening formwork is installed according to the on-site construction layout to ensure the verticality and flatness of the formwork; the formwork is firmly fixed using materials such as braces and tension screws. Braces are set every 500mm along the height direction of the window opening. The spacing of the tension screws should not be greater than 500mm, and the distance from the bottom and top should not be greater than 200mm. Exhaust holes are set on the window cover to discharge bubbles generated during vibration to ensure the quality of concrete pouring. When pouring concrete, it should be poured from both sides of the window opening at the same time to avoid formwork deviation. Pay attention to uniform vibration during the pouring process to ensure that the concrete is poured densely. After the concrete pouring is completed, it should be maintained in time. After reaching a certain strength, the formwork is removed.

[0042] The anti-leakage template structure of the exterior window wall of this embodiment is simple in structure, and the window sill can be made into a tongue-and-groove structure, which can form a natural water retaining platform structure, effectively blocking the intrusion of rainwater and other moisture, not only improving the waterproof performance of the building, but also reducing the maintenance cost and inconvenience caused by leakage problems, with good practical effect and strong application ability.
