[0002] A grouting sleeve is an assembly consisting of a specially processed sleeve, matching grouting material, and reinforcing bars. When connecting reinforcing bars, fast-hardening, non-shrink grouting material is injected, and the reinforcing bars and sleeve are connected by the bonding and interlocking action between the materials.

[0003] A testing device and method for testing prefabricated vertical sleeve grouting connection parts is disclosed in CN119198393A. Specifically, it includes a base plate and a sleeve. A side plate is fixedly installed on the top of the base plate. A grout discharge hole is provided on one side of the top end of the sleeve. A grout injection hole is provided on one side of the bottom end of the sleeve. The sleeve is filled with grouting material. Both ends of the sleeve are provided with reinforcing bars, and the opposite ends of the reinforcing bars are located in the grouting material.

[0004] Existing testing devices can only obtain the overall compressive strength data of the specimen, making it difficult to observe and analyze the specific changes of different parts of the specimen during the compression process. They also cannot locate the weak points of the specimen through multi-position testing, which is not conducive to a comprehensive evaluation of the grouting quality of the sleeve. To solve the above problems, we propose a prefabricated building sleeve grouting testing device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-6 The prefabricated building sleeve grouting testing equipment includes a table 1, a frame 2 fixedly installed on the table 1, a testing mechanism 3 installed on the frame 2, and a camera device 4 facing the testing mechanism 3 installed on the table 1. The camera device 4 is used to film the testing process and concrete specimens.

[0026] The testing mechanism 3 includes two templates 5 fixedly installed on the upper end of the frame 2. The two templates 5 are symmetrically distributed. A base plate 6 is provided below the two templates 5. Slide grooves 7 are provided on both sides of the frame 2. A support plate 8 is provided inside the frame 2. The two ends of the support plate 8 are slidably installed in the slide grooves 7 on both sides. A vertical rod 9 is fixed at the bottom of the base plate 6. The vertical rod 9 passes through the support plate 8 and is slidably installed on the support plate 8. A spring 10 is provided on the outer sleeve of the vertical rod 9. The two ends of the spring 10 are fixedly connected to the support plate 8 and the base plate 6 respectively. A sealing element 11 is provided at the gap between the two templates 5. The sealing elements 11 on both sides, the two templates 5 and the base plate 6 together form a columnar mold cavity. Two sets of driving components are provided on the frame 2. The driving components are connected to the sealing elements 11 and drive the sealing elements 11 to squeeze the test specimen in the mold cavity.

[0027] The compressive strength of the specimen is tested and evaluated by having staff examine the compressed area of ​​the specimen after it is squeezed.

[0028] The drive assembly includes a hydraulic rod 12 fixedly mounted on the frame 2, a block 13 fixedly mounted on the output end of the hydraulic rod 12, an eccentric shaft 14 rotatably mounted on the block 13, the upper end of the eccentric shaft 14 fixedly connected to the bottom eccentric part of the sealing component 11, a gear 15 fixedly mounted on the eccentric shaft 14, an electric telescopic rod 16 fixedly mounted on the frame 2, a rack 17 fixedly mounted on the output end of the electric telescopic rod 16, and the rack 17 meshing with the gear 15.

[0029] Elastic plates 18 are fixedly connected to both sides of the eccentric shaft 14, and the lower ends of the elastic plates 18 are fixedly connected to the block 13. Pressure rods 23 are fixedly installed on the upper ends of the sealing components 11, and the pressure rods 23 are located above the mold cavity. Limiting grooves 19 are provided on both sides of the frame 2, extending into the tray 8. Limiting blocks 20 are provided on both sides of the frame 2, inserting into the limiting grooves 19 and limiting the tray 8. Limiting holes 21 are provided on the frame 2, and a limiting rod 22 passes through the lower end of the vertical rod 9. One end of the limiting rod 22 passes through the limiting hole 21 and limits the vertical rod 9.

[0030] Insert the limiting block 20 into the limiting groove 19 to keep the support plate 8 fixed. The limiting rod 22 passes through the vertical rod 9 and the limiting hole 21 and limits the vertical rod 9, thereby keeping the bottom plate 6 above the vertical rod 9 in a state of sealing the bottom surface of the mold cavity. Add an appropriate amount of concrete into the mold cavity and wait for it to solidify before conducting the test.

[0031] The electric telescopic rod 16 drives the rack 17, giving it a tendency to move horizontally. Within a certain range, the driving force of the electric telescopic rod 16 causes the rack 17 to mesh with the gear 15, which in turn causes the eccentric shaft 14 to rotate. The sealing member 11 rotates eccentrically around the eccentric shaft 14, and one side corner of the sealing member 11 rotates into the mold cavity and squeezes the side of the concrete specimen. By setting the elastic plate 18, the eccentric shaft 14 and the gear 15 can automatically reset after the angle deflection.

[0032] Then the hydraulic rod 12 is driven downward, with the driving force within a certain range, and the block 13 tends to move downward. The block 13, eccentric shaft 14, sealing part 11, gear 15 and pressure rod 23 move downward with it. The pressure rod 23 presses down on the top of the specimen and performs compressive performance testing on the top of the specimen.

[0033] Afterwards, the limiting rod 22 is removed, allowing the vertical rod 9 and the base plate 6 to move up and down. The hydraulic rod 12 is driven downwards, and the pressure rod 23 presses down on the specimen, causing it to detach from the mold cavity. The base plate 6 moves down along with the specimen, and the spring 10 contracts. After demolding, the limiting blocks 20 on both sides are removed, allowing the sliding support plate 8 to slide down. The vertical rod 9, the base plate 6, and the specimen on the support plate 8 all move down a certain distance, allowing the specimen to be removed. The specimen is then observed and its compressive strength is evaluated.

[0034] The camera device 4 records the entire testing process and the condition of the specimen (such as crack formation and deformation), providing visual evidence for subsequent compressive performance evaluation.

[0035] By setting up the detection mechanism 3, the electric telescopic rod 16 drives the rack 17 to move horizontally, and the gear 15 drives the eccentric shaft 14 to rotate, so that the sealing part 11 rotates eccentrically to squeeze the side of the specimen, thereby realizing the lateral pressure resistance test; the hydraulic rod 12 presses down to drive the block 13, the eccentric shaft 14, the sealing part 11 and the pressure rod 23 to move down synchronously, and the pressure rod 23 directly presses down on the top of the specimen, thereby realizing the vertical pressure resistance test, and the specimen can be tested from multiple directions.

[0036] The dual limiting design of limiting block 20 and limiting rod 22 ensures the stability of the mold cavity structure during the testing process; the limiting is released sequentially during demolding, and combined with the sliding function of tray 8, the specimen can be efficiently removed, improving testing efficiency and ease of operation.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
