[0003] During the construction of the concrete chimney cylindrical wall 2, slurry leakage is likely to occur at the joints between the concrete chimney cylindrical wall 1, the steel formwork 2 for chimney cylindrical wall construction and the tension rod 3. Dark stains are likely to form at the slurry leakage part of the cylindrical wall, resulting in a decline in the appearance quality of the chimney. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a slurry leakage plugging device, aiming to at least solve the technical problems existing in the above-mentioned prior art. To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A slurry leakage plugging device includes:
[0006] A rubber frustum, the rubber frustum has an inclined outer peripheral surface, and a circular cavity one is axially opened in the rubber frustum;
[0007] A metal cylinder, a circular cavity two is axially opened in the metal cylinder, and an inclined cavity which can be fitted with the inclined outer peripheral surface of the rubber frustum is also opened on one side of the metal cylinder, and the inclined cavity is communicated with the circular cavity two;
[0008] A metal threaded column, a circular cavity three is axially opened in the metal threaded column;
[0009] Wherein, the metal cylinder is rotatably sleeved on the outer periphery of the metal threaded column through the circular cavity two.

[0011] As a further scheme of the utility model: external threads are arranged on the outer periphery of the metal threaded column, and the metal cylinder is rotatably sleeved on the outer periphery of the metal threaded column through the external threads.
[0012] As a further scheme of the utility model: the axial depth of the inclined cavity is less than the axial length of the rubber frustum.
[0013] As a further solution of the present utility model: the maximum longitudinal length of the inclined cavity is less than the longitudinal length of the rubber frustum.
[0014] The present utility model has the following beneficial effects:
[0015] The present utility model is provided with a slurry leakage plugging device, which at least includes three components: a rubber frustum, a metal cylinder and a metal threaded column. The metal threaded column is rotatably sleeved on the tie rod, the metal cylinder is rotatably sleeved on the metal threaded column, and the rubber frustum is also movably sleeved on the tie rod. The rubber frustum is located between the metal cylinder and the steel formwork. During the concrete construction of the chimney wall, by rotating the metal threaded column, the metal cylinder is driven to move along the tie rod towards the steel formwork, so that the rubber frustum is closely attached to the steel formwork. At the same time, under the extrusion of the metal cylinder, the rubber frustum shrinks.

[0024] In addition, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0025] Please refer to Figure 1 As shown, during the construction process of the concrete chimney wall 2, leakage of mortar is likely to occur at the joints between the concrete chimney wall 1, the steel formwork 2 for chimney wall construction, and the tension bolts 3. Dark stains are likely to form at the mortar leakage areas on the wall, resulting in a decline in the appearance quality of the chimney.
[0026] To solve the problem of mortar leakage existing in the prior art, please refer to Figures 2 - 4 As shown, the present utility model provides a mortar leakage plugging device that can prevent mortar leakage at the joints between the tension bolts 3 and the chimney wall 2. The mortar leakage plugging device at least includes three components: a rubber frustum 4, a metal cylinder 5, and a metal threaded post 6. Among them, the metal threaded post 6 is rotatably sleeved on the tension bolt 3, the metal cylinder 5 is rotatably sleeved on the metal threaded post 6, and the rubber frustum 4 is also movably sleeved on the tension bolt 3, and the rubber frustum 4 is located between the metal cylinder 5 and the formwork 2. As Figure 4 As shown, during the concrete construction process of the chimney wall 1, by rotating the metal threaded post 6, the metal cylinder 5 is driven to move along the tension bolt 3 towards the formwork 2, so that the rubber frustum 4 closely fits onto the formwork 2. At the same time, under the extrusion of the metal cylinder 5, the rubber frustum 4 shrinks. While the rubber frustum 4 closely fits onto the formwork 2, it also tightly wraps around the tension bolt 3, so that the concrete slurry no longer flows out from the joint between the tension bolt 3 and the chimney wall 1, thereby avoiding the formation of dark stains at the mortar leakage areas on the wall and improving the appearance quality of the chimney.
[0027] Please refer to Figure 2As shown, in one embodiment, the rubber frustum 4 has an inclined outer peripheral surface 41, and a circular cavity 42 is axially formed inside the rubber frustum 4. The diameter of the circular cavity 42 is slightly larger than the diameter of the tension screw rod 3. The rubber frustum 4 is movably sleeved on the tension screw rod 3 through the circular cavity 42, and the rubber frustum 4 itself has shrinkability. Under external extrusion, the rubber frustum 4 can shrink. While closely fitting to the steel formwork 2, the rubber frustum 4 also tightly wraps around the outer periphery of the tension screw rod 3.
[0028] Please refer to Figure 2 As shown, in one embodiment, a circular cavity 51 is axially formed inside the metal cylinder 5. The metal cylinder 5 is rotatably sleeved on the outer periphery of the metal threaded column 6 through the circular cavity 51. Rotating the metal cylinder 5 can cause the metal cylinder 5 to axially move on the outer periphery of the metal threaded column 6. And an inclined cavity 52 that can fit with the inclined outer peripheral surface 41 of the rubber frustum 4 is formed on one side of the metal cylinder 5. The inclined cavity 52 communicates with the circular cavity 51. When the metal cylinder 5 axially moves towards the steel formwork 2 on the outer periphery of the metal threaded column 6, the inclined cavity 52 fits with the inclined outer peripheral surface 41 of the rubber frustum 4 to push the rubber frustum 4 towards the steel formwork 2.
[0029] Furthermore, the axial depth of the inclined cavity 52 is less than the axial length of the rubber frustum 4, and the maximum longitudinal length of the inclined cavity 52 is less than the longitudinal length of the rubber frustum 4. After the metal cylinder 5 pushes the rubber frustum 4 to closely fit to the surface of the steel formwork 2, as the metal cylinder 5 continues to advance, the inclined cavity 52 squeezes the rubber frustum 4, causing the rubber frustum 4 to shrink and tightly wrap around the tension screw rod 3.
[0030] Please refer to Figure 2 As shown, in one embodiment, a circular cavity 61 is axially formed inside the metal threaded column 6. The inner wall of the circular cavity 61 is provided with internal threads. The metal threaded column 6 is rotatably sleeved on the outer periphery of the tension screw rod 3 through the internal threads. By rotating the metal threaded column 6, the metal threaded column 6 can axially move on the outer periphery of the tension screw rod 3. External threads are provided on the outer periphery of the metal threaded column 6. The metal cylinder 5 is rotatably sleeved on the outer periphery of the metal threaded column 6 through the external threads. By rotating the metal cylinder 5, the metal cylinder 5 can axially move on the outer periphery of the metal threaded column 6.
[0031] It should be noted that in reality, a full-length PVC casing may be added to the outer periphery of the tension screw rod 3. At this time, the metal threaded column 6 cannot rotate forward using the internal threads. The structure of the metal threaded column 6 can be improved to enable the metal threaded column 6 to tightly wrap around the smooth PVC casing, and then rotate the metal cylinder 5 to push the rubber frustum 4.
[0032] In summary, a slurry leakage plugging device provided by the present utility model advances the rubber frustum 4 to closely fit the steel formwork 2 by rotating the metal threaded column 6 and / or the metal cylinder 5. At the same time, as the metal cylinder 5 advances, the inclined cavity 52 of the metal cylinder 5 squeezes the rubber frustum 4 to cause the rubber frustum 4 to contract and tightly wrap around the tension rod 3. Therefore, during the construction of the concrete chimney wall 1, the concrete slurry no longer flows out from the joint between the tension rod 3 and the chimney wall 1.
[0033] The above has described the preferred embodiments of the present utility model in detail, and it should not be considered as limiting the scope of implementation of the present utility model. Any equal changes and improvements made according to the scope of the application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
