[0002] During the construction of precast beams, there are gaps at the joint where the bottom formwork and the side formwork are joined, which are prone to slurry leakage, thus making it difficult to ensure the quality of the precast beam concrete. To solve this problem, the traditional method often uses a slurry stop tape pasted with glue along the length direction of the beam on both sides of the bottom formwork, which can effectively prevent slurry leakage. However, the traditional slurry stop tape is time-consuming to paste and is easily damaged during use. When re-pasting, it is difficult to remove the old slurry stop tape. Therefore, a new slurry stop method is proposed. Summary of the Utility Model

[0021] Refer to Figure 1 , the present utility model provides a formwork structure for precast beams with anti-slurry leakage, solving the problems that the existing use of traditional slurry-stop tapes is time-consuming for pasting, and it is easy to be damaged during use, and it is difficult to remove the old slurry-stop tapes when re-pasting. By providing the keyway and the sealing strip, the sealing strip is filled between the keyway and the side mold, thereby blocking the gap, achieving the purpose of preventing slurry leakage, and having convenient operation, and the used sealing strip is also convenient to remove. By providing the first fixing member and the second fixing member, the two side molds are mutually close and fixed, ensuring the stability of the mold.

[0022] Refer to Figure 1 , showing a cross-sectional view of the formwork structure for precast beams with anti-slurry leakage of the present utility model.

Refer to Figure 3, showing a cross-sectional view after the second fixing member of the precast beam formwork structure for preventing slurry leakage of the present utility model is tightened. The following will be combined with Figures 1 to 3 , the precast beam formwork structure for preventing slurry leakage of the present utility model will be described.

[0023] As Figures 1 to 3 shown, a precast beam formwork structure for preventing slurry leakage of the present utility model includes: a bottom form 1; side forms 3 provided on both sides of the bottom form 1; key grooves 2 provided at the bottom of the bottom form 1 and close to the corresponding side forms 3, the notch of the key groove 2 facing the corresponding side form 3; a sealing strip 4 provided in the key groove 2, and a part of the sealing strip 4 extends out of the notch of the key groove 2 to seal the gap between the side form 3 and the bottom form 1.

[0024] In a preferred embodiment, the key groove 2 is a channel steel.

[0025] In a specific embodiment, a support 8 is fixedly provided at the lower end of the bottom form 1.

[0026] In a preferred embodiment, the support 8 is formed by concrete pouring.

[0027] In a specific embodiment, a support 5 is further included and is provided outside the side form 3, and the lower end of the support 5 is closely attached to the side surface of the support 8.

[0028] In a preferred embodiment, the side form 3 is fixed to the support 5.

[0029] In a preferred embodiment, the side form 3 is fixed to the support 5 by bolts.

[0030] In a specific embodiment, the height of the support 5 is higher than the height of the side form 3.

[0031] In a specific embodiment, a first fixing member 6 is provided at the upper end of the support 5, and the first fixing member 6 is located above the side form 3. Placing the first fixing member 6 above the side form 3 can prevent the concrete from solidifying the first fixing member 6 and causing inconvenience in disassembly.

[0033] In a preferred embodiment, the first fixing member 6 and the second fixing member are tension bolts.

[0034] In a preferred embodiment, nuts are provided at both ends of the first fixing member 6 and the second fixing member 7.

[0035] In a specific embodiment, the sealing strip 4 is made of rubber. Setting the sealing strip 4 to be a soft rubber material enables the sealing strip 4 to deform when the side mold 3 is in close contact with the sealing strip 4, thereby filling the gap between the side mold 3 and the keyway 2, and thus preventing the concrete in the mold from leaking.

[0036] In a specific embodiment, the sealing strip 4 is a cylinder, and its diameter is the same as the size of the keyway 2. By setting the sealing strip 4 with the same size as the notch of the keyway 2, the sealing strip 4 can completely fill the notch of the keyway 2, thereby achieving the purpose of preventing slurry leakage.

[0037] In a specific embodiment, an extrusion member is provided on the outer side of the side mold 3 near the connection with the bottom mold 1, and the part of the extrusion member corresponding to the sealing strip 4 is in close contact, so that the sealing strip 4 deforms and thus closely adheres to the gap between the side mold 3 and the bottom mold 1.

[0038] The following is a detailed description of the use process of the precast beam formwork structure for preventing slurry leakage of the present invention.

[0039] The operator fixes and assembles the side mold 3 and the corresponding bracket 5 with bolts, installs the assembled mold on both sides of the bottom mold 1, passes the first fixing member 6 and the second fixing member 7 through the two molds, and by tightening the nuts, the first fixing member 6 and the second fixing member 7 pull the two side molds 3 closer to each other and gradually close to the bottom mold 1.

[0040] The side mold 3 compresses the sealing strip 4, causing the sealing strip 4 to deform to completely block the notch of the keyway 2 and the gap between the side mold 3 and the keyway 2, thereby achieving the purpose of preventing slurry leakage.

[0041] The present invention has been described in detail above in combination with the embodiments with the accompanying drawings. Those of ordinary skill in the art can make various variations of the present invention according to the above description. Therefore, some details in the embodiments should not constitute a limitation to the present invention, and the protection scope of the present invention will be defined by the scope of the appended claims.
