The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments.

[0026] Embodiment 1

This embodiment provides a construction device for preventing slurry leakage in the post-cast strip with advanced water stop at the bottom plate, including a cushion layer 1, characterized in that: a formwork assembly 2 is arranged on the upper side of the cushion layer 1, a post-cast strip area 3 is arranged between the formwork assemblies 2, and a pouring area 4 is arranged outside the formwork assembly 2;

[0028] Among them, the formwork assembly 2 includes an L-shaped plate 21 arranged at the upper end of the cushion layer 1, sealing plates 22 arranged on both sides of the L-shaped plate 21, and a baffle member 5 arranged at the upper end of the L-shaped plate 21.

[0029] Specifically, a central boss 11 is arranged at the upper end of the cushion layer 1, a first boss 12 and a second boss 13 are arranged on both sides of the upper end of the cushion layer 1, an outer boss 14 is arranged on the side of the upper end of the cushion layer 1 away from the second boss 13, and a fixing boss 15 is arranged at the outer end of the cushion layer 1.

[0030] Furthermore, the fixing boss 15 is in contact with the lower end of the sealing plate 22, thereby forming an integral whole of the entire device, playing a supporting role for the sealing plate 22 and preventing the sealing plate 22 from sagging.

[0031] Furthermore, the L-shaped plate 21 is located between the first boss 12 and the second boss 13, and the clamping stability of the L-shaped plate 21 is improved by the clamping of the first boss 12 and the second boss 13.

[0032] Furthermore, the arrangement of the sealing plate 22 can seal both sides of the post-cast strip area 3 and the pouring area 4, improving the airtightness of the device.

[0033] Embodiment 2

[0034] Referring to Figure 3-4 , which is the second embodiment of the present utility model. Different from the previous embodiment, the baffle member 5 includes a card slot 51 arranged at the upper end of the L-shaped plate 21, a card plate 52 arranged on the upper side of the L-shaped plate 21, and a card lift 53 arranged at the lower end of the card plate 52. A triangular plate 54 is arranged at the outer end of the card plate 52.

[0035] Specifically, a first steel bar 23 is arranged on the upper side between the L-shaped plates 21, a second steel bar 24 is arranged on the lower side between the L-shaped plates 21, and a first mesh steel bar 25 is arranged at the lower end inside the L-shaped plates 21.

[0036] Further, the clip 51 and the card slot 53 are engaged with each other, so as to connect the card board 52 and the L-shaped plate 21. By virtue of the height of the triangular plate 54 being greater than that of the casting area 4, the anti-leakage effect on the post-cast strip area 3 can be improved.

[0037] Further, the diameter of the first steel bar 23 is greater than that of the second steel bar 24. The second steel bar 24 is welded to the first mesh steel bars 25 to improve the connection firmness between the first mesh steel bars 25. The second steel bar 24 is fixedly connected to both sides of the L-shaped plate 21 to play a role in fixedly supporting the L-shaped plates 21 on both sides.

[0038] Further, the first mesh steel bars 25 are arranged in the inner concave area of the L-shaped plate 21. Through the densely arranged mesh structure, the supporting effect on the device is improved, and deformation is avoided.

[0039] Embodiment 3

[0040] Refer to Figure 5-6 , which is the third embodiment of the present utility model. Different from the previous embodiment, it includes that a third steel bar 26 is arranged between the sealing plates 22, and second mesh steel bars 27 are arranged on the upper and lower sides between the sealing plates 22.

[0041] Specifically, a first cushion plate area 16 is arranged between the central boss 11 and the first boss 12, and a second cushion area 17 is arranged between the second boss 13 and the outer boss 14.

[0042] Further, the arrangement of the third steel bar 26 can improve the connection firmness of the sealing plates 22 and the stable supporting force. The second mesh steel bars 27 are arranged on the upper and lower sides of the third steel bar 26 to improve the stability of the casting area 4, prevent it from flowing into the post-cast strip area 3, and improve the anti-leakage effect of the device.

[0043] Further, since the concrete cushion provides a stable foundation to support the above structure and disperse the load, a first cushion plate area 16 is arranged between the central boss 11 and the first boss 12, and a second cushion area 17 is arranged between the second boss 13 and the outer boss 14. Among them, the materials of the first cushion plate area 16 and the second cushion area 17 can add high-strength and high-ductility fibers or penetration enhancers to the traditional concrete to improve the tensile strength and crack resistance of the concrete, effectively prevent cracks and breakages, and improve the overall stability of the cushion layer 1.

[0044] Principle, start. After the staff place the device in the post-cast strip area 3, high-ductility fiber concrete or concrete penetration enhancer is filled in the second cushion layer area 17 to improve the long-term stability of the cushion layer 1 and reduce the occurrence of slurry leakage from the casting area 4 to the post-cast strip area 3 in the future. Through the setting of the sealing plates 22 on both sides, the sealing performance of the formwork can be enhanced, and the slurry leakage problem caused by the insecure fixation of the formwork can be reduced. The third steel bars 26 arranged between the sealing plates 22 can improve the rigidity of the formwork and avoid the deformation of the formwork caused by the lateral pressure of the concrete during pouring, thereby preventing the concrete from flowing into the post-cast strip area 3. When the height of pouring concrete in the casting area 4 is about to reach the bottom horizontal line of the clamping plate 52, stop pouring concrete into the casting area 4. Through the triangular plate 54 fixedly connected to the outside of the clamping plate 52, with the help of the vertical surface of the triangular plate 54, it can play a role in resisting the slurry leakage from the casting area 4 to the post-cast strip area 3. After pouring the post-cast strip area 3, after taking the triangular plate 54 upward, then fill and level the concrete in the card slot 53 at the upper end of the L-shaped plate 21. Then pour the post-cast strip area 3 again. First, fill the ductility fiber concrete or concrete penetration enhancer in the first cushion plate area 16, and with the help of the first mesh steel bars 25 arranged at the lower end inside the L-shaped plate 21, the second steel bars 24 of the first steel bars 23 between the L-shaped plate 21, the stability of the device can be improved, thereby improving the anti-slurry leakage function of the device.
