Description

Technical Field

[0001] This utility model belongs to the field of building assembly technology, specifically a vertical grouting sleeve connection structure for shear walls. Background Technology

[0002] In modern prefabricated wall structures, reinforcing bars are placed at the top of the wall, and sleeves are located at the bottom of the wall with the sleeve opening facing downwards. After the sleeve is connected to the reinforcing bar, grout is injected into the sleeve. The grouting method is as follows: use a grouting machine to inject grout from the grouting pipe at the bottom of the side of the sleeve. When grout flows out of the grout outlet pipe at the top, it indicates that the grout has been filled, and grouting is stopped.

[0003] It was learned that during actual grouting, manual use of rubber plugs and hammers is required to block the discharge holes to prevent grout from flowing out. However, in practice, multiple holes may discharge grout at the same time, which requires workers to spend a long time sealing them, resulting in a large amount of grout leakage and waste, and making the grouting process troublesome.

[0004] For example, in the case of CN209163232U, the sleeve is grouted before the sleeve is inserted and connected. Whether the sleeve is full can be visually observed, which avoids the problem of insufficient grouting of the sleeve, ensures the construction quality, and simplifies the operation process compared to the original method.

[0005] The aforementioned patent discharges excess grout when the reinforcing bar is inserted into the sleeve. Although sealing is not required, it still wastes grout. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a vertical grouting sleeve connection structure for shear walls, which has the advantages of quickly sealing multiple holes and avoiding grout waste.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vertical grouting sleeve connection structure for shear walls, including a wall body and a grouting sleeve embedded inside the wall body, wherein the injection end and the discharge end of the grouting sleeve both penetrate the wall body and extend to the outside;

[0008] The adjustment mechanism includes a connecting sleeve that is threadedly fixed to the injection end and the discharge end of the grouting sleeve. A partition is fixed inside the connecting sleeve at one end away from the grouting sleeve. A notch communicating with the grouting sleeve is opened on one side of the surface of the partition, and the notch is always located at the upper position.

[0009] A T-shaped cylinder is rotatably disposed in the middle of the partition. A sector-shaped baffle and a bushing are slidably fitted on the surface of the T-shaped cylinder from left to right. The sector-shaped baffle is used to seal the gap.

[0010] The end of the T-shaped cylinder away from the bushing is threadedly connected to a nut plate that limits the bushing.

[0011] Preferably, the adjustment mechanism further includes a T-shaped groove in the middle of the partition, wherein the end of the T-shaped cylinder away from the bushing is located in the T-shaped groove and rotates to achieve a limiting position.

[0012] Preferably, the T-shaped cylinder has external threads on one end surface of the bushing, and symmetrical limit grooves are formed on both sides of the surface of the T-shaped cylinder.

[0026] 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 protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides a vertical grouting sleeve connection structure for shear walls, including a wall 2, which is configured as a prefabricated wall 2 and a grouting sleeve 3 embedded inside the wall 2. It should be noted that the connection method between the grouting sleeve 3 and the wall 2 is existing and conventional; the specific assembly method will not be detailed here. The final state (as shown) Figure 1 As shown, the adjustment mechanism 100 can be pre-installed at the factory or assembled on-site by construction personnel during grouting. Construction personnel can rotate the injection end of the grouting sleeve 3 to determine whether to install the adjustment mechanism 100. Both the injection end and the discharge end of the grouting sleeve 3 penetrate the wall 2 and extend to the outside. Both the injection end and the discharge end of the grouting sleeve 3 are existing structures. Reinforcing bars can be inserted into the longitudinal sleeve of the grouting sleeve 3 to achieve connection and fixation of different walls 2.

[0028] The adjusting mechanism 100 includes a connecting sleeve 101 threadedly fixed to the injection end and the discharge end of the grouting sleeve 3. The inner walls of both the injection end and the discharge end of the grouting sleeve 3 are threaded, thus securing them to the external threads of the connecting sleeve 101 and achieving a seal. Figure 2 As shown), a partition plate 102 is fixed at the end of the connecting sleeve 101 away from the grouting sleeve 3. A space for placing a fan-shaped baffle 103 is reserved between the partition plate 102 and the outer end face of the connecting sleeve 101. This space can accommodate the bushing 104 and store multiple structures to achieve a neat device. A notch 109 is opened on one side of the surface of the partition plate 102. The notch 109 is connected to the grouting sleeve 3. The notch 109 is always located at the upper position. The size of the notch 109 can be set according to actual needs, as long as the filled grout can flow out smoothly.

[0029] The adjusting mechanism 100 also includes a T-groove 110 located at the center of the partition 102. The end of the T-shaped cylinder 108 away from the bushing 104 is located within the T-groove 110 and rotates to achieve a limited position. The surface of the T-shaped cylinder 108 at the end located on the bushing 104 is provided with external threads (e.g., ...). Figure 5 As shown, it should be noted that the limiting groove 115 does not have external threads and its surface is a smooth plane. The T-shaped cylinder 108 has symmetrically formed limiting grooves 115 on both sides, extending to the large round head of the T-shaped cylinder 108. A through hole is formed in the center of the fan-shaped baffle 103, and symmetrical limiting strips 114 that slide inside the limiting groove 115 are fixed to both sides of the inner wall of the through hole. A through hole is formed in the center of the bushing 104, and symmetrical limiting strips 113 that slide inside the limiting groove 115 are fixed to both sides of the inner wall of the through hole. The surface of the second limiting strip 114 is flush with the inner wall of the bushing 104. The surface of the limiting strip 113 abuts against the surface of the limiting groove 115 and can slide. The surface of the T-shaped cylinder 108 is slidably fitted with a fan-shaped baffle 103 and a bushing 104 from left to right. The diameter of the fan-shaped baffle 103 is smaller than the diameter of the connecting sleeve 101 and larger than the diameter of the notch 109. The fan-shaped baffle 103 is used to seal the notch 109. The side of the fan-shaped baffle 103 facing the partition 102 can also be fixed with plastic material, thereby increasing the sealing performance of the notch 109 through the deformation of the plastic. Both sides of the end of the fan-shaped baffle 103 facing the partition 102 are provided with chamfers to facilitate the rotation and movement of the fan-shaped baffle 103.

[0030] A nut plate 107 is threadedly connected to the end of the T-shaped cylinder 108 away from the bushing 104. The nut plate 107 limits the bushing 104 and thus pushes the bushing 104 to slide on the surface of the T-shaped cylinder 108.

[0031] A limiting rod 111 is fixedly mounted on one side of the sleeve 104 to the fan-shaped baffle 103. The limiting rod 111 is circular, and a spring 112 is sleeved on the outside of the limiting rod 111. One end of the spring 112 is fixed to the surface of the fan-shaped baffle 103, and the other end of the spring 112 abuts against the surface of the side plate 105. The elastic force of the spring 112 needs to be set high enough to make the fan-shaped baffle 103 tightly abut against the surface of the partition 102, thereby increasing the sealing of the notch 109. The side plate 105 is symmetrically fixed on the surface of the sleeve 104. The side plate 105 has a movable hole on the side facing the limiting rod 111. Under normal conditions, the limiting rod 111 moves through the movable hole to achieve the effect of limiting and guiding.

[0032] An L-shaped handle 106 for easy gripping is fixed on one side of the plate 105 and the limiting rod 111, and the length of the lower end of the L-shaped handle 106 does not exceed the length of the connecting sleeve 101.

[0033] The principle and process of this utility model:

[0034] Before grouting, the user can install multiple adjustment mechanisms 100 at the grout outlet and allow the notch 109 to leak out, thereby achieving the effect of venting.

[0035] The user fixes the pipe of the grouting device to the injection end of the grouting sleeve 3. Then, the grouting device works to inject grout into the grouting sleeve 3. When grout leaks out of the notches 109 at the discharge ends of multiple grouting sleeves 3 in sequence, the specific operation is as follows:

[0036] The user holds the L-shaped handle 106 and rotates it clockwise or counterclockwise. The L-shaped handle 106 will drive the side plate 105 to rotate, which in turn will drive the bushing 104 to rotate. Since the limiting strip 113 is set in the limiting groove 115, the T-shaped cylinder 108 will rotate in the T-shaped groove 110 of the partition 102 through the limiting strip 113. The T-shaped cylinder 108 will drive the limiting strip 114 to rotate through the limiting groove 115, which will drive the fan-shaped baffle 103 to rotate. The fan-shaped baffle 103 will gradually close the notch 109 and block one of the discharge ends of the grouting sleeve 3.

[0037] The sealing operation of the discharge end of the other grouting sleeves 3 is as described above. By rotating the fan-shaped baffle 103, rapid sealing can be achieved, which has the advantages of quickly sealing multiple holes and avoiding grout waste.

[0038] When the seal between the sector baffle 103 and the notch 109 is not tight, the user can rotate the nut plate 107 with a tool. The nut plate 107 rotates on the T-shaped cylinder 108 and squeezes the bushing 104 through the thread action. When the bushing 104 moves, it pushes the side plate 105 to slide on the limiting rod 111 and squeezes the spring 112. Under the force of the spring 112, the sector baffle 103 is pushed. During the pushing process, the first limiting strip 113 and the second limiting strip 114 slide in the limiting groove 115, thereby increasing the sealing between the sector baffle 103 and the notch 109. Therefore, the problem of reduced sealing due to wear after repeated use is avoided. The improved sealing avoids slurry leakage and thus saves slurry.

[0039] It should be noted that if the grouting sleeve 3 is also equipped with the adjustment mechanism 100, it will not affect the grouting fluid. After the pipeline of the grouting device is removed, the L-shaped handle 106 needs to be rotated in time to seal the gap 109.
