Description

Technical Field

[0001] The utility model belongs to the technical field of grouting sleeves, and specifically relates to a sealing mechanism for grouting sleeves of prefabricated components of assembled bridges. Background Technique

[0002] In the construction of assembled bridges, the grouting sleeve connection technology of prefabricated components is a crucial link, which is directly related to the overall strength, stability and durability of the bridge structure. As a key component for connecting prefabricated components, the sealing performance of the grouting sleeve directly affects the grouting effect of the grouting material and the reliability of the subsequent structure.

[0003] During the use of traditional grouting sleeves, the problem of poor sealing often occurs. This is mainly because the liquid outlet pipe (grout outlet) and the liquid inlet pipe (grouting port) of the grouting sleeve fail to effectively prevent the grouting material from flowing out through unexpected paths during the grouting process, resulting in defects such as incomplete grouting and air bubbles inside the grouting sleeve. These defects will not only reduce the connection strength of the grouting sleeve, but may also pose a threat to the overall structural safety of the bridge.

[0004] Therefore, in view of the above problems, a sealing mechanism for grouting sleeves of prefabricated components of assembled bridges is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problem that the liquid outlet pipe (grout outlet) and the liquid inlet pipe (grouting port) of the grouting sleeve fail to effectively prevent the grouting material from flowing out through unexpected paths during the grouting process, resulting in defects such as incomplete grouting and air bubbles inside the grouting sleeve, a sealing mechanism for grouting sleeves of prefabricated components of assembled bridges is proposed.

[0008] The sealing mechanism is respectively arranged on the outer walls of the liquid outlet pipe and the liquid inlet pipe. The sealing mechanism includes a sealing plug and a sealing member. The sealing plug is embedded in the inner wall of the liquid outlet pipe. The sealing member includes a sealing bead arranged on the outer wall of the liquid outlet pipe. One end of the sealing bead is placed on the outer wall of the liquid outlet pipe, and the other end of the sealing bead is placed inside the liquid outlet pipe.

A control mechanism is arranged on the outer wall of the liquid outlet pipe; to ensure the smooth progress of the grouting process and the sealing of the inside of the grouting sleeve.

[0009] Preferably, the connecting mechanism includes a connecting block provided on the side wall of the sealing bead. The connecting block is fixedly connected to the sealing bead. The connecting block is embedded in the inner wall of the second chute. The second chute is opened on the inner wall of the liquid outlet pipe. The connecting block and the second chute are connected by a tension spring, which makes the sealing effect between the liquid outlet pipe and the sealing plug better.

[0010] Preferably, the control mechanism includes a rotating ring and a fixed ring provided on the outer wall of the liquid outlet pipe. The fixed ring is fixedly connected to the liquid outlet pipe. The rotating ring is rotatably connected to the liquid outlet pipe. The inner wall of the rotating ring is in contact with the sealing bead.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 - 4 , the present utility model provides a grouting sleeve sealing mechanism for prefabricated bridge components, including a grouting sleeve body 1, a liquid outlet pipe 2, a liquid inlet pipe 3 and a sealing mechanism;

[0027] The liquid outlet pipe 2 and the liquid inlet pipe 3 are arranged on one side of the grouting sleeve body 1;

[0028] The sealing mechanisms are respectively arranged on the outer walls of the liquid outlet pipe 2 and the liquid inlet pipe 3. The sealing mechanism includes a sealing plug 5 and a sealing member. The sealing plug 5 is embedded in the inner wall of the liquid outlet pipe 2. The sealing member includes a sealing bead 8 arranged on the outer wall of the liquid outlet pipe 2. One end of the sealing bead 8 is placed on the outer wall of the liquid outlet pipe 2, and the other end of the sealing bead 8 is placed inside the liquid outlet pipe 2. The sealing bead 8 is in contact with the outer wall of the sealing plug 5. The sealing bead 8 is connected to the liquid outlet pipe 2 through a connecting mechanism. A control mechanism is arranged on the outer wall of the liquid outlet pipe 2.

[0029] After pouring non-shrinkage grouting material, the sealing plug 5 can be timely embedded in the inner walls of the liquid outlet pipe 2 and the liquid inlet pipe 3, and at the same time, the sealing member is used to fix the sealing plug 5 inside the liquid outlet pipe 2, avoiding the non-shrinkage grouting material flowing out from the inside of the liquid outlet pipe 2, resulting in problems such as incomplete grouting or air bubbles in the grouting sleeve body 1, ensuring the smooth progress of the grouting process and the sealing performance inside the grouting sleeve. This not only improves the connection strength of the grouting sleeve but also ensures the tight connection between precast components, laying a solid foundation for the overall stability and durability of the bridge structure.

[0030] The connecting mechanism includes a connecting block 13 arranged on the side wall of the sealing bead 8. The connecting block 13 is fixedly connected to the sealing bead 8. The connecting block 13 is embedded in the inner wall of the second chute 12. The second chute 12 is opened on the inner wall of the liquid outlet pipe 2. The connecting block 13 is connected to the second chute 12 through a tension spring 14.

[0031] Through the arranged connecting mechanism, the sliding of the sealing bead 8 on the inner wall of the liquid outlet pipe 2 can be controlled, so that when the sealing bead 8 is embedded in the groove on the inner wall of the rotating ring 6, under the action of the tension spring 14, the part of the sealing bead 8 placed on the inner wall of the liquid outlet pipe 2 will be flush with the inner wall of the liquid outlet pipe 2, facilitating the insertion of the sealing plug 5. When the sealing bead 8 is removed from the groove on the inner wall of the rotating ring 6, at this time, the part of the sealing bead 8 placed on the inner wall of the liquid outlet pipe 2 will squeeze the sealing plug 5, making the sealing bead 8 and the sealing plug 5 in interference fit, thus strengthening the connection between the sealing plug 5 and the liquid outlet pipe 2 and making the sealing effect between the liquid outlet pipe 2 and the sealing plug 5 better.

[0032] The control mechanism includes a rotating ring 6 and a fixed ring 4 arranged on the outer wall of the liquid outlet pipe 2. The fixed ring 4 is fixedly connected to the liquid outlet pipe 2. The rotating ring 6 is rotatably connected to the liquid outlet pipe 2. The inner wall of the rotating ring 6 is in contact with the sealing bead 8. A groove matching the sealing bead 8 is opened on the inner wall of the rotating ring 6. A handle 7 is arranged on the outer wall of the rotating ring 6. The handle 7 is embedded between the fixed rods 10. The fixed rods 10 are fixedly installed on the side wall of the fixed ring 4.

[0033] By controlling the rotation of the handle 7, the rotation ring 6 can be driven to rotate, thereby controlling the position of the sealing bead 8 so that the sealing bead 8 can switch states. When the sealing plug 5 needs to be inserted into the inner part of the liquid outlet pipe 2, the sealing bead 8 can be flush with the inner wall of the liquid outlet pipe 2, thus facilitating the insertion of the sealing plug 5 into the inner part of the liquid outlet pipe 2. After the sealing plug 5 is inserted into the inner part of the liquid outlet pipe 2, it can be switched to another state so that there is an interference fit between the sealing bead 8 and the sealing plug 5, thereby enhancing the sealing effect between the sealing plug 5 and the liquid outlet pipe 2.

[0034] The bottom end of the handle 7 is embedded in the inner wall of the first chute 11. The first chute 11 is opened on the outer wall of the rotation ring 6. The handle 7 is connected to the side wall of the first chute 11 through a spring 9. By pulling the handle 7, the handle 7 can be disengaged from between the fixed rods 10, and then the handle 7 is rotated to drive the rotation ring 6 to rotate. When it rotates to a suitable position, the handle 7 is released. Under the action of the first chute 11, the handle 7 will be embedded between the fixed rods 10, thereby fixing the position of the rotation ring 6, which facilitates the fixing of the positions of the sealing beads 8 in different states.

[0035] There are three fixed rods 10. The minimum distance between every two fixed rods 10 is greater than the distance between the two sides of the handle 7. The length between the two ends of the fixed rod 10 is equal to the minimum distance from the side wall of the fixed ring 4 to the side wall of the handle 7 away from the fixed ring 4. The spacing between the fixed rods 10 is greater than or equal to the diameter of the sealing bead 8, and the spacing between the fixed rods 10 is less than the spacing between two sealing beads 8. The handle 7 can be embedded between the fixed rods 10, thereby fixing the rotation ring 6.

[0036] The sealing beads 8 are evenly distributed in a circumferential array with the axis of the liquid outlet pipe 2 as the array center, which can fix the sealing plug 5 more evenly and make the sealing effect better.

[0037] The outer diameter of the sealing plug 5 is equal to the inner diameter of the liquid outlet pipe 2, which facilitates the insertion of the sealing plug 5 into the inner part of the liquid outlet pipe 2. At the same time, one end of the sealing plug 5 close to the liquid outlet pipe 2 can be set to be conical to play a guiding role and facilitate the alignment of the sealing plug 5 with the port of the liquid outlet pipe 2. The length of the sealing plug 5 is greater than the length from the end of the liquid outlet pipe 2 to the side wall of the fixed ring 4, which can ensure that the sealing member plays a role.

[0038] Working principle: Before grouting, the sealing bead 8 is placed in the groove on the inner wall of the rotating ring 6. At this time, the sealing bead 8 is flush with the inner wall of the liquid outlet pipe 2. After grouting is completed, the sealing plug 5 is inserted into the inside of the liquid outlet pipe 2 until the end of the sealing plug 5 is completely inserted into the inside of the liquid outlet pipe 2. Then, the handle 7 is pulled, so that the handle 7 slides inside the first chute 11 until the handle 7 disengages from between the fixed rods 10. Then, the handle 7 is rotated, so that the handle 7 drives the rotating ring 6 to rotate. At this time, the rotating ring 6 will squeeze the sealing bead 8, causing the sealing bead 8 to slide towards the inner wall of the liquid outlet pipe 2 and squeeze the outer wall of the sealing plug 5, thereby fixing the sealing plug 5 and the liquid outlet pipe 2, improving the sealing effect between the liquid outlet pipe 2 and the sealing plug 5. When the handle 7 rotates between the other two fixed rods 10, the handle 7 is released. Under the action of the spring 9, the handle 7 is driven to slide on the inner wall of the first chute 11 until the handle 7 is inserted between the fixed rods 10, thereby fixing the sealing plug 5 inside the liquid outlet pipe 2. Repeat the above operation to insert the sealing plug 5 into the inside of the liquid inlet pipe 3.

[0039] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
