Description

Technical Field

[0001] The present invention relates to the technical field of bond strength detection, and specifically provides a detection device for the bond strength of grouting material. Background Art

[0002] The bond strength of grouting material refers to the ability of concrete to resist the slippage of steel bars, usually represented by the bond strength of concrete. The bond strength is the shear stress along the contact surface between the steel bar and the concrete, that is, the bonding stress. It varies with the type and appearance of the steel bar and its embedding position in the concrete, and is also related to the self-strength of the concrete.

[0003] However, Patent No.: CN119064128 B discloses a detection device for the bond strength between concrete and steel bars, which relates to the technical field of bond strength detection. The present invention includes a bottom plate, on which four columns are equidistantly fixed; a top plate, fixed on the upper end surfaces of the four columns, and the four columns are located near the four top corners of the top plate; a downward pressing cylinder body, fixed in the middle position of the top plate; a lower pressing plate, fixed on the upper end surface of the bottom plate; a positioning component, configured to be four, all fixed on the upper end surface of the bottom plate, and respectively located in the middle positions of the four sides of the lower pressing plate; a downward pressing component, slidably arranged on the four columns and connected to the output end of the downward pressing cylinder body; wherein, a planted steel bar concrete is placed on the lower pressing plate, and a plurality of steel bars are embedded in the planted steel bar concrete; in the present invention, different steel bars are embedded in one planted steel bar concrete, so that there is only one set of variables during detection, thereby comparing the bond strength between concrete and steel bars in different situations.

[0004] The following problems exist in the process of using the detection device for the bond strength between concrete and steel bars: By embedding one steel bar in one group of concrete, there will be no difference in the bonding force when one group of concrete solidifies.

[0026] Embodiment 1, as Figure 1-2 shown, the present invention provides a technical solution: a grout bond strength detection device, including a detection frame 1, a longitudinal slide rail 2 and a cylinder 3. The longitudinal slide rail 2 is installed on the inner wall of the detection frame 1, and the cylinder 3 is arranged at the top of the detection frame 1. And a pressure frame 4 adapted to the longitudinal slide rail 2 is installed at the output end of the cylinder 3. A fixed slide rail 5 is installed at the bottom end of the pressure frame 4, and a moving frame 11 is arranged inside the fixed slide rail 5. An activity slot 12 is opened inside the moving frame 11, and a contact block 18 is arranged inside the activity slot 12. A sleeve 19 is arranged at the top end of the inner wall of the activity slot 12, and a T-shaped rod 20 connected to the contact block 18 is installed on the outer wall of the sleeve 19. A second spring 27 is sleeved on the outer walls of the sleeve 19 and the T-shaped rod 20. A pressure sensor 21 is arranged on the inner wall of the sleeve 19. A limiting mechanism for fixing the position of the moving frame 11 is arranged inside the activity slot 12. A collection slot 6 is opened inside the detection frame 1, and a collection box 7 is arranged inside the collection slot 6. An observation door panel 26 is hinged on the outer wall of the detection frame 1. A single-chip microcomputer 28 is arranged at the top of the detection frame 1. The limiting mechanism includes a guide rod 13 and an insertion frame 14. The guide rod 13 is arranged inside the activity slot 12, and an insertion frame 14 penetrating through the fixed slide rail 5 is installed on the outer wall of the guide rod 13. A first spring 16 is sleeved on the outer wall of the guide rod 13. A tooth block 15 is installed on the outer wall of the insertion frame 14. A gear 17 is installed inside the activity slot 12 through a bearing, and the outer wall of the gear 17 is meshed with the outer wall of the tooth block 15. By pressing the insertion frame 14 to move inside the guide rod 13 to squeeze the first spring 16, and at the same time the tooth block 15 is meshed with the outer wall of the gear 17, then the two insertion frames 14 are squeezed towards the middle position of the first spring 16, which is convenient for the moving frame 11 to slide left and right to a suitable position inside the fixed slide rail 5. Then release the insertion frame 14, and drive the two insertion frames 14 to insert into the limiting holes penetrating through the fixed slide rail 5 under the action of the self-elastic force of the first spring 16, which is convenient for fixing the position of the moving frame 11 inside the fixed slide rail 5. This structure is simple to operate and convenient to use.

[0027] Embodiment 2, as Figure 1-6As shown in the figure, the present invention provides a technical solution: a grouting material bond strength detection device, which includes a plurality of bond boxes 8 arranged inside a detection frame 1, and limiting grooves 9 are opened on both sides of the bond box 8. Insertion plates 10 are arranged inside the limiting grooves 9. A long groove 22 is opened inside the detection frame 1, and a cleaning mechanism for impurities is arranged inside the long groove 22. The cleaning mechanism includes a lead screw 24 and a motor 25. The motor 25 is installed on the outer wall of the detection frame 1, and the output end of the motor 25 is installed with a lead screw 24 passing through the long groove 22 through a coupling. A fixing frame 23 passing through the long groove 22 is arranged inside the long groove 22 through a slideway, and the inner wall of the fixing frame 23 is engaged with the outer wall of the lead screw 24. A transverse cleaning groove communicating with the collection groove 6 is opened on one side of the long groove 22. By starting the motor 25 to drive the lead screw 24 to move in the slideway of the long groove 22, the fixing frame 23 cleans the impurities and smaller debris inside the detection frame 1 and falls into the collection box 7 through the transverse cleaning groove for collection.

[0028] Working principle: First, connect to the external power supply. The operator can insert the insertion plate 10 into the limiting groove 9 to fix it at the bond box 8, then pour concrete slurry and place steel bars in the middle position, and then place multiple groups of bond boxes 8 inside the detection frame 1. Then start the cylinder 3 to push the contact block 18 downward to insert it into the steel frame position, and continue to start the cylinder 3 to push the contact block 18 to insert it into the steel bar position. The contact block 18 drives the T-shaped rod 20 to squeeze the pressure sensor 21, causing the second spring 27 to contract. Then the position of the T-shaped rod 20 squeezes the position of the pressure sensor 21. The pressure sensor 21 records the pressure value and sends it to the single-chip microcomputer 28. By connecting the external display to the single-chip microcomputer 28, it is convenient for the operator to observe the data in real time. The operator can continue to check if the steel bar position slips, indicating that the steel bar and the concrete are loosened. At this time, the cylinder 3 can be turned off, and the pressure value of the pressure sensor 21 is recorded to complete the bond strength detection. When debris appears when pressing the bond box 8, and the operator opens the observation door panel 26 and takes out the bond box 8 one by one, the motor 25 can be started to drive the lead screw 24 to move in the slideway of the long groove 22, so that the fixing frame 23 cleans the impurities and smaller debris inside the detection frame 1;

[0029] This structure can detect multiple groups of wrapping boxes 8. Due to the different sizes and volumes, the interference can be reduced by adjusting the distance between the wrapping boxes 8, or the number of wrapping boxes 8 in the fixed slide rail 5 can be adjusted to correspond to the number of multiple groups or a single group of wrapping boxes 8. The specific operation is as follows: By pressing the insertion frame 14 to move in the guide rod 13 and squeeze the first spring 16, at the same time, the tooth block 15 meshes with the outer wall of the gear 17. Then, the two insertion frames 14 are squeezed towards the middle position of the first spring 16, facilitating the sliding of the moving frame 11 to the appropriate position left and right in the fixed slide rail 5. Then, release the insertion frame 14. Under the action of the self-elastic force of the first spring 16, the two insertion frames 14 are driven to insert into the limiting holes penetrating the fixed slide rail 5, facilitating the fixation of the position of the moving frame 11 in the fixed slide rail 5. This structure is simple to operate and convenient to use.

[0030] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present invention shall not depart from the essence and scope of the technical solution of the present invention.
