Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated walls, and specifically relates to a slurry outlet plug for a prefabricated wall. Background Art

[0002] The grouting process of prefabricated walls is to inject grout through the grouting holes, and then flow out through the grouting holes, so as to judge whether the grouting in the prefabricated wall is completed. In order to ensure that the slurry is not wasted too much, it is generally required for multiple people to carry out the operation. One of them injects grout through the grouting holes, and the other operators need to pay attention to the grouting holes at all times to observe whether there is slurry flowing out of the grouting holes. When it is found that the slurry starts to flow out of the grouting holes, it proves that the slurry filling in the prefabricated wall is complete, and the operator needs to use the grouting hole plug to plug the grouting hole in time to prevent the waste of slurry.

[0003] The slurry hole plugs used in the prior art are generally ordinary rubber plugs, which are removed after the slurry in the prefabricated wall solidifies. Usually, operators are required to pay attention to the slurry holes at all times, and judge whether the slurry filling in the prefabricated wall is completed by whether there is slurry flowing out of the slurry holes. This requires operators to pay attention at all times and there is no way to avoid slurry waste. Utility Model Content

[0004] The purpose of the utility model is to provide a prefabricated wall slurry outlet plug to solve the problems in the prior art that the prefabricated wall slurry outlet cannot intuitively judge whether the slurry is filled without wasting slurry, and requires operators to pay attention all the time, resulting in waste of human resources and reduced efficiency.

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0025] Embodiment 1:

[0026] See attached Figures 1 to 5. A prefabricated wall slurry hole plug, used for blocking slurry and judging whether the slurry is filled, comprises a fixing part, a pressing part and a blocking part; the fixing part is fixed at the slurry hole; the blocking part is installed in the pressing part; the pressing part is used to squeeze the fixing part so that the fixing part is pressed against the wall of the slurry hole; the blocking part is used to block the slurry; the blocking part can move in the pressing part due to the squeezing of the slurry. As can be seen from the above structure, a prefabricated wall slurry hole plug of the utility model comprises three parts, namely a fixing part, a pressing part and a blocking part. The three parts are processed separately and used in combination when in use to achieve the effect of sealing the slurry hole and judging whether the slurry is filled. Specifically, the fixing part is made of a tough rubber material, and includes two cylindrical sections of different diameters. The first cylindrical section has a smaller diameter, which is adapted to the diameter of the slurry outlet hole and can be directly inserted into the slurry outlet hole. The second cylindrical section has a larger diameter and is larger than the diameter of the slurry outlet hole to complete the limiting function. The two cylindrical sections of the fixing part are integrally arranged, and the interiors are all integrally arranged with through holes. The clamping part specifically includes a third cylindrical section with a threaded structure on the outside and a fourth cylindrical section integrally connected to the third cylindrical section. The diameter of the third cylindrical section is slightly larger than the diameter of the through hole in the fixing part, and the diameter of the fourth cylindrical section is larger than the diameter of the through hole of the fixing part. The third cylindrical section of the clamping part cooperates with the through hole of the fixing part through the threaded mechanism of the outer wall, and the third cylindrical section is inserted into the through hole of the fixing part by screwing. Because the fixing part is made of a tough rubber material, the third cylindrical section can apply force to make the fixing part tightly fit against the wall of the slurry outlet hole. Close contact increases sealing and stability. The setting of the fourth cylindrical segment plays a limiting role to prevent the clamping part from being completely inserted into the through hole of the fixing part. A through hole that runs through the third cylindrical segment and the fourth cylindrical segment is also provided in the clamping part. A hollow structure is provided inside the fourth cylindrical segment, and an opening is formed by the through hole at one end away from the third cylindrical segment, and the diameter of the opening is smaller than the diameter of the fourth cylindrical segment. The blocking part specifically includes a connecting rod and two discs, a large disc and a small disc. The two ends of the connecting rod are respectively connected to the centers of the two discs. The diameter of the small disc is equivalent to the diameter of the through hole in the third cylindrical segment in the clamping part, and the diameter of the large disc is equivalent to the diameter of the fourth cylindrical segment, and can move inside the fourth cylindrical segment. The diameter of the large disc limits the large disc to move only inside the fourth cylindrical segment. The small disc is provided in the through hole of the third cylindrical segment, and cooperates with the through hole to form a closure, which can prevent the slurry from flowing out through the through hole.The utility model provides a prefabricated wall slurry outlet plug. First, a fixing part is inserted into the inner wall of the slurry outlet hole until the second cylindrical section is tightly connected with the outside of the slurry outlet hole. The blocking part is installed in advance in the pressing part during the processing. After the fixing part is installed, the third cylindrical section of the pressing part is screwed into the through hole of the fixing part, so that there is no gap between the fixing part and the inner wall of the slurry outlet hole, forming a good seal. The large disk at the initial position is set in the fourth cylindrical section away from the opening. When the slurry starts to fill the slurry outlet hole, the slurry will contact the small disk that contacts first and generate extrusion force on the small disk. The small disk is driven by the force to drive the connecting rod and the large disk to move to the outside of the slurry outlet hole until the large disk is tightly contacted with the opening of the fourth cylindrical section. It can be judged that the slurry filling has been completed, and the continued filling of the slurry can be stopped. After the slurry is cooled and solidified, the slurry outlet plug of the utility model is removed to complete the installation of the prefabricated wall. The utility model can intuitively judge whether the slurry is filled completely without wasting the slurry, and does not require operators to pay attention all the time to cause waste of human resources and reduce efficiency.

[0027] Embodiment 2:

[0028] See attached Figures 1 to 5 . On the basis of the first embodiment, the fixing part includes a first limiting end 1 and a plunger segment 2; the plunger segment 2 is fixedly connected to the first limiting end 1; a first through hole 3 is provided in the center of the plunger segment 2, and the first through hole 3 extends to the first limiting end 1; the diameter of the first limiting end 1 is larger than the cross-sectional diameter of the plunger segment 2. It can be seen from the above structure that, specifically, the fixing part is composed of the first limiting end 1 and the plunger segment 2, the first limiting end 1 and the plunger segment 2 are integrally arranged, and the first through hole 3 of the first limiting end 1 and the plunger segment 2 is penetrated inside, wherein the plunger segment 2 matches the shape of the slurry outlet hole, is cylindrical, and is used to contact the inner wall of the slurry outlet hole, the cross-section of the first limiting end 1 is circular, and the diameter is larger than the diameter of the slurry outlet hole, and is used to limit the plunger segment 2 on the slurry outlet hole to prevent the plunger segment 2 from directly passing through the slurry outlet hole.

[0029] The clamping part is a cylindrical section 4 with an external threaded structure; a second through hole 5 is provided at the center of the cylindrical section 4; the cross-sectional diameter of the cylindrical section 4 is slightly larger than the diameter of the first through hole 3; a second limiting end 6 is provided at one end of the cylindrical section 4; the diameter of the second limiting end 6 is larger than the diameter of the first through hole 3, and is used to limit the second limiting end 6 on the first limiting end 1. It can be seen from the above structure that the specific clamping part is composed of a second limiting end 6 and a cylindrical section 4, and the second limiting end 6 and the cylindrical section 4 are integrally arranged. A second through hole 5 penetrating the cylindrical section 4 and the second limiting end 6 is provided in the clamping part. The cross-sectional diameter of the cylindrical section 4 is slightly larger than the diameter of the first through hole 3, ensuring that pressure can be applied when the cylindrical section 4 contacts the plunger section 2 to ensure the overall sealing. The diameter of the second limiting end 6 is larger than the diameter of the first through hole 3, and can limit the insertion length of the cylindrical section 4. The setting of the threaded structure can make the cylindrical section 4 be inserted into the first through hole 3 faster by screwing during installation, and the plunger section 2 is made of tough plastic material, which has a certain toughness and can cooperate with the threaded structure outside the cylindrical section 4. When a perfect match is achieved, a force can be applied to the plunger section 2 toward the inner wall of the slurry outlet hole, so that the plunger section 2 is in close contact with the slurry outlet hole to ensure sealing.

[0030] Embodiment three:

[0031] See attached Figures 1 to 5 . On the basis of the second embodiment, the second limiting end 6 includes an upper connecting part and a lower connecting part; one end of the lower connecting part is provided with an external thread; the end of the upper connecting part corresponding to the lower connecting part is provided with an internal thread, and the upper connecting part and the lower connecting part are detachably connected by threaded cooperation; the lower connecting part is integrally arranged with the cylindrical section 4. It can be seen from the above structure that the second limiting end 6 is composed of an upper connecting part and a lower connecting part, and the lower connecting part is integrally arranged with the cylindrical section 4, and the outer side surface of the end of the lower connecting part away from the cylindrical section 4 is provided with an external thread, and the inner side surface at the corresponding position of the upper connecting part and the lower connecting part is provided with an internal thread. The detachable connection is achieved by threaded cooperation between the upper connecting part and the lower connecting part, and the detachability of the second limiting end 6 can facilitate the installation and replacement of the blocking part.

[0032] The second limiting end 6 has a hollow structure inside; an opening 7 is provided on the side of the second limiting end 6 away from the cylindrical section 4; the diameter of the opening 7 is smaller than the diameter of the second limiting end 6. As can be seen from the above structure, the second limiting end 6 is a hollow structure formed by an upper connecting part and a lower connecting part, the upper connecting part is in the shape of an end cap, and an opening 7 is provided on the end away from the cylindrical section 4, and the diameter of the opening 7 is smaller than the diameter of the entire end cap. The setting of the opening is used to observe the displacement of the internal blocking part and prevent the blocking part from falling from the opening 7.

[0033] The blocking portion includes a first disc 8, a connecting rod 9 and a second disc 10; the two ends of the connecting rod 9 are respectively connected to the centers of the first disc 8 and the second disc 10; the diameter of the first disc 8 is equivalent to the diameter of the second through hole 5; the diameter of the second disc 10 is larger than the diameters of the opening 7 and the second through hole 5. As can be seen from the above structure, the specific blocking portion is composed of the first disc 8, the second disc 10 and the connecting rod 9 connecting the centers of the first disc 8 and the second disc 10. The diameter of the first disc 8 is equivalent to the diameter of the second through hole 5, and is used to cooperate with the second through hole 5 to form a closure to block the slurry from passing through the second through hole 5. The diameter of the second disc 10 is larger than the diameter of the second through hole 5, and is installed inside the second limiting end 6. Its diameter is also larger than the diameter of the opening 7 on the second limiting end 6. During assembly, the upper connecting part is detached from the lower connecting part by rotating the upper connecting part, and then the first disc 8 of the blocking part is first inserted into the second through hole 5 until the second disc 10 is stuck in the second limiting end 6. , and then the upper connecting part is connected with the lower connecting part through threaded cooperation. At this time, the second disc 10 is inside the second limit end 6, and in the initial state, the second disc 10 is at a position away from the opening 7. When the grouting machine starts to fill the slurry, until the slurry begins to squeeze the first disc 8 and drives the first disc 8 to move outward along the axial direction of the second through hole 5, the first disc 8 also moves the second disc 10 outward along the axial direction of the second through hole 5 through the connecting rod 9. When the second disc 10 moves to close the opening 7, it can be judged that the slurry filling in the prefabricated wall is basically completed, the grouting machine is stopped, and the slurry inside the prefabricated wall is waited for to solidify, and then the slurry hole plug can be removed.

[0034] The first disc 8 moves in the second through hole 5; the second disc 10 moves in the second limit end 6. As can be seen from the above structure, the first disc 8 is limited in the second through hole 5 and cooperates with the second through hole 5 to form a closed state, blocking the slurry from flowing out through the second through hole 5; the second disc 10 is limited in the second limit end 6, and the movement of the second disc 10 is observed to determine whether the slurry is filled.

[0035] Embodiment 4:

[0036] See attached Figures 1 to 5 . On the basis of the third embodiment, the first disc 8 is provided with a rubber sleeve. As can be seen from the above structure, the rubber sleeve is provided on the outer surface of the first disc 8, which can increase the friction between the first disc 8 and the plunger section 2, and avoid the first disc 8 from loosening and driving the second disc 10 to move due to vibrations generated at the construction site, resulting in misjudgment. Moreover, the detachable second limit end 6 can better assemble the blocking part and facilitate the replacement of the rubber sleeve.

[0037] The plunger section 2 is made of rubber material. As can be seen from the above structure, the plunger section 2 is made of a rubber material with toughness, and cooperates with the threaded structure on the outside of the cylindrical section 4. The cylindrical section 4 can be inserted into the plunger section 2, and the threaded structure squeezes the plunger section 2, so that the plunger section 2 is in close contact with the inner wall of the grouting hole, thereby improving stability and sealing.

[0038] The first stopper 1 is made of rubber material. As can be seen from the above structure, the first stopper 1 is also made of a rubber material with toughness. Similarly, the cylindrical section 4 first contacts the first stopper 1 during installation. Only with a certain toughness can the cylindrical section 4 be installed smoothly and avoid the problem of being unable to be inserted.

[0039] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
