[0002] A precast beam is a concrete beam component that is prefabricated according to design requirements. During the casting process of a precast beam, in order to prevent grout from flowing out from both ends of the bottom formwork and to ensure that the precast beam is formed completely and dimensionally accurate, a grout-stopping device for the bottom plate of the precast beam is required.

[0003] Chinese patent application number CN202122960677.8 provides a grout-stopping device for the bottom plate of a precast beam. This solution prevents grout leakage at the joint between the side of the precast beam and the bottom mold of the precast beam by setting a grout-stopping strip at the bottom of the precast beam, thus improving the appearance quality of the precast beam concrete.

[0004] Most precast beam bottom slab grout-stopping devices use filling to block the grout leakage path. If the size of the filling material is not suitable, the ease of operation of the grout-stopping device for precast beam bottom slabs will be reduced and its adaptability will be low. Therefore, a new grout-stopping device for precast beam bottom slabs is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a grout-stopping device for the bottom slab of a precast beam. (Refer to...) Figures 1-5A precast beam bottom slab grout-stopping device includes a precast beam side mold 1; the precast beam side molds 1 are symmetrically distributed, and a precast platform 3 is movably connected to the inner end of the precast beam side mold 1. A beam-making platform 2 is provided at the bottom end of the precast platform 3. The inner end of the precast platform 3 has symmetrically distributed operating grooves 5, and a sealing strip 6 is slidably connected to the inner end of each operating groove 5. An adjusting plate 10 is slidably connected to the outer end of the sealing strip 6, and multiple snap-fit ​​joints 11 are fixedly connected to the outer end of the adjusting plate 10. By installing the sealing strip 6 and the adjusting plate 10... When the grout-stopping strip 7 fills and moves the sealing strip 6, the screw 14 will be rotated by the throttle 15 to engage with the threaded cylinder 13, thereby allowing the adjustment plate 10 connected to the front end of the screw 14 to be adjusted in position. The moving adjustment plate 10 can form a connection and sealing structure again at the outer end of the sealing strip 6, thus enabling the device to achieve a more precise seal and ensuring that there is no grout leakage at the connection between the precast beam side mold 1 and the beam casting platform 2. This gives the precast beam bottom plate grout-stopping device multiple sealing structures, increasing its adaptability.

[0026] Reference Figure 2 and Figure 5 Multiple slots 12 are provided at the inner end of the sealing strip 6. The slots 12 and the connectors 11 are movably connected. By installing the slots 12 and the connectors 11, the connectors 11 can be adjusted simultaneously with the movement of the adjusting plate 10. The multiple connectors 11 are engaged with the slots 12 provided in the sealing strip 6 under the action of force, thereby further increasing the sealing and grout-stopping effect between the precast beam side mold 1 and the precast platform 3.

[0027] Reference Figures 2-4 The inner end of the precast beam side mold 1 is fixedly connected with a threaded cylinder 13. The inner end of the threaded cylinder 13 is threadedly connected with a screw 14. The outer end of the screw 14 is fixedly connected with a handle 15. By installing the threaded cylinder 13, the threaded cylinder 13 is located inside the precast beam side mold 1. When the screw 14 rotates, it can perform threaded action with the threaded cylinder 13, thereby making it easier for the screw 14 to adjust its position and drive the adjustment plate 10 to shrink and extend.

[0028] Reference Figure 4 and Figure 5 Both ends of the adjusting plate 10 are fixedly connected to limit blocks 16. The inner end of the limit block 16 is slidably connected to a slide rod 17. By installing the slide rod 17, when the adjusting plate 10 is adjusted, a pair of limit blocks 16 can be adjusted simultaneously with the movement of the adjusting plate 10. The moving limit block 16 slides on the outer end of the slide rod 17. The slide rod 17 restricts the limit block 16 and the adjusting plate 10, so that the adjusting plate 10 is more stable when it is adjusted and sealed, and will not flip over.

[0029] Reference Figure 3-5The two ends of the slide rod 17 are fixedly connected to the limiting head 18. The slide rod 17 passes through to the outer end of the precast beam side mold 1, and one limiting head 18 extends to the outside of the precast beam side mold 1. By installing the limiting head 18, the limiting head 18 can connect one end of the slide rod 17 to the precast beam side mold 1, so that the section of the slide rod 17 that passes through the interior of the precast beam side mold 1 is more stable when used with the limiting block 16.

[0030] Reference Figure 1 and Figure 5 The outer end of the precast beam side mold 1 is fixedly connected with a reinforcing platform 4, and the inner end of the precast beam side mold 1 is provided with an adjustment groove 19. By installing the reinforcing platform 4, the reinforcing platform 4 can form a reinforced structure at the outer end of the precast beam side mold 1, making the precast beam side mold 1 structure more stable during casting.

[0031] Reference Figure 2 The operating groove 5 is internally connected to a grout-stopping strip 7, and the inner end of the precast platform 3 is threadedly connected to a threaded component 8. The inner end of the sealing strip 6 is fixedly connected to a slider 9. By installing the grout-stopping strip 7 and the threaded component 8, when the grout-stopping device is in use, the threaded component 8 is rotated and adjusted, which can drive the upper sealing strip 6 to move in position. In conjunction with the grout-stopping strip 7, it can fit against the end of the beam bottom mold, so that the gap between the precast beam side mold 1 and the precast platform 3 can be initially filled, forming a continuous closed interface, preventing grout leakage, and improving the effectiveness of the grout-stopping device for the precast beam bottom plate.

[0032] Working principle: When using this device, first place the sealing strip 6 and the grout-stopping strip 7 inside a pair of operating grooves 5. Then rotate the threaded part 8, which moves to adjust the position of the sealing strip 6 above. Together with the grout-stopping strip 7, it can fit against the end of the beam bottom mold, allowing the gap between the precast beam side mold 1 and the precast platform 3 to be initially filled, forming a continuous closed interface to prevent grout leakage. Then rotate a pair of handles 15. The threaded cylinder 13 is located inside the precast beam side mold 1. When the screw 14 rotates, it can engage with the threaded cylinder 13, thereby... The screw 14 is adjusted to drive the adjustment plate 10. The moving adjustment plate 10 can form a connection and sealing structure again at the outer end of the sealing strip 6, thereby enabling the device to achieve a more precise seal and ensuring that there is no grout leakage at the connection between the precast beam side mold 1 and the beam casting platform 2. The snap-fit ​​connector 11 can be adjusted simultaneously with the movement of the adjustment plate 10. Multiple snap-fit ​​connectors 11 are engaged with the snap-fit ​​groove 12 set in the sealing strip 6 under the action of force, thereby further increasing the sealing and grout-stopping effect between the precast beam side mold 1 and the precast platform 3, so that the grout-stopping work of the device can be carried out smoothly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
