Description

Technical Field

[0001] This utility model belongs to the field of anchorage force testing technology, specifically a rebar anchorage force testing device. Background Technology

[0002] Reinforcing bar anchorage refers to the process of encasing reinforcing bars in concrete to enhance the connection between the concrete and the reinforcing bars, making the building more robust. The purpose is to enable both to work together to withstand various stresses. This is achieved by drilling a hole in a specific direction through a weak surface into intact rock mass, inserting a prestressed anchor cable (reinforcing bar), and then cementing the hole to form a structure with a certain tensile strength. An anchorage force testing equipment is then used to clamp and pull the anchor cable (reinforcing bar) to test its strength. However, traditional anchorage force testing equipment, after clamping and fixing one end of the anchor cable (reinforcing bar), can experience significant pull-out force, causing the clamping structure to separate from the anchor cable (reinforcing bar), thus affecting normal testing. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a rebar anchorage force testing device, including a mounting base. Four inclined support legs are fixedly installed at equal intervals in a ring at the bottom of the mounting base. Support seats are fixedly installed at the bottom of each of the four support legs. Four vertical rods are fixedly installed at the top of the mounting base. A top plate is fixedly installed between the tops of the four vertical rods. A reversible motor is installed at the top of the top plate. The output end of the reversible motor is connected to a threaded shaft that movably passes through the top plate. A threaded tube is threadedly connected to the lower part of the threaded shaft. A tensile testing instrument is installed at the bottom of the threaded tube. A sling is connected to the bottom of the tensile testing instrument. A clamping component is connected to the bottom of the sling. The rebar body is clamped in the middle of the clamping component.

[0004] Preferably, the clamping component includes a cylindrical block with two symmetrically opened inclined slots at the bottom of the cylindrical block. A spring is fixedly connected to the top of each of the two inclined slots, and a movable block that is movably inserted into the inclined slot is fixedly connected to the bottom of each of the two springs. A guide groove is opened in the middle of each of the two movable blocks, and a fixing pin located inside the guide groove is fixedly installed inside each of the two inclined slots. Clamping blocks are symmetrically fixedly installed at the bottom of the two movable blocks, and the upper part of the rebar body is clamped between the two clamping blocks.

[0005] Preferably, the bottom of the cylindrical block has two symmetrical vertical sliding grooves, which are respectively connected to the middle of the opposite sides of the two inclined slots. The opposite sides of the two moving blocks are fixedly installed with extrusion slide plates, which are respectively located inside the two vertical sliding grooves. The surface of the cylindrical block is threaded with a threaded sleeve. The bottom of the threaded sleeve extrudes the two extrusion slide plates, causing the moving blocks to move. The movement of the two moving blocks will stretch the two springs.

[0015] 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.

[0016] Depend on Figures 1 to 4 The present invention includes a mounting base 1, on which four inclined support legs 2 are fixedly installed at equal intervals in a ring at the bottom. A reinforcing rod is fixedly connected between any two adjacent support legs 2. Support seats 3 are fixedly installed at the bottom of each of the four support legs 2. Four vertical rods 4 are fixedly installed at the top of the mounting base 1. A top plate 5 is fixedly installed between the tops of the four vertical rods 4. A forward and reverse motor 6 is installed at the top of the top plate 5. A threaded shaft 7 that movably passes through the top plate 5 is connected to the output end of the forward and reverse motor 6. A threaded tube 8 is threadedly connected to the lower part of the threaded shaft 7. A tensile testing instrument 9 is installed at the bottom of the threaded tube 8. A sling 10 is connected to the bottom end of the tensile testing instrument 9. A clamping component 11 is connected to the bottom of the sling 10. A rebar body 12 is clamped in the middle of the clamping component 11. The rebar body 12 is embedded in the reinforced concrete floor slab.

[0017] The clamping component 11 includes a cylindrical block 13. Two inclined slots 14 are symmetrically opened at the bottom of the cylindrical block 13. A spring 15 is fixedly connected to the top of each of the two inclined slots 14. A movable block 16 is movably inserted into the inclined slot 14 at the bottom of each of the two springs 15. A guide groove 17 is opened in the middle of each of the two movable blocks 16. A fixing pin 18 located inside the guide groove 17 is fixedly installed inside each of the two inclined slots 14. Clamping blocks 19 are symmetrically fixedly installed at the bottom of each of the two movable blocks 16. The upper part of the rebar body 12 is clamped between the two clamping blocks 19. Clamping protrusions are opened on the opposite sides of the clamping blocks 19.

[0018] Two vertical sliding grooves 20 are symmetrically opened at the bottom of the cylindrical block 13. The two vertical sliding grooves 20 are respectively connected to the middle of the opposite side of the two inclined slots 14. The opposite side of the two moving blocks 16 are fixedly installed with extrusion slide plates 21. The two extrusion slide plates 21 are respectively located inside the two vertical sliding grooves 20. The surface of the cylindrical block 13 is threadedly connected with a threaded sleeve 22. The bottom of the threaded sleeve 22 extrudes the two extrusion slide plates 21, causing the moving blocks 16 to move. The movement of the two moving blocks 16 will stretch the two springs 15, thereby effectively clamping and fixing the upper part of the anchor body 12.

[0019] Specifically, the upper part of the rebar body 12 is positioned between the two clamping blocks 19. Then, by rotating the threaded sleeve 22 on the surface of the cylindrical block 13, the threaded sleeve 22 is moved downward, causing the two extrusion slides 21 to be extruded downward. The downward movement of the two extrusion slides 21 will cause the two moving blocks 16 to tilt downward inside the two inclined slots 14 and stretch the spring 15. The tilting downward movement of the two moving blocks 16 will cause the two clamping blocks 19 to move relative to each other and clamp and fix the upper part of the rebar body 12. At the same time, the clamping protrusions on the clamping blocks 19 can firmly clamp and fix the rebar body 12.

[0020] A through hole 23 is provided in the middle of the mounting base 1. The sling 10 passes through the through hole 23. A fixing block 24 is fixedly installed at the lower part of the threaded tube 8. The surfaces of the four vertical rods 4 are movably fitted with sleeves 25. All four sleeves 25 are fixedly connected to the fixing block 24, so that the anchoring force can be effectively tested.

[0021] Specifically, after the upper part of the rebar body 12 is fixedly clamped between the two clamping blocks 19, the threaded shaft 7 is rotated by starting the forward and reverse motor 6 (the forward and reverse motor 6 is connected to an external power source). The rotation of the threaded shaft 7 causes the threaded tube 8 to move stably upward through the fixing block 24 and the sleeve 25. The threaded tube 8 will drive the tensile testing instrument 9, the sling 10 and the cylindrical block 13 to move upward. At this time, the tensile data can be obtained through the tensile testing instrument 9 (the model of the tensile testing instrument 9 is: GALOCE-GWD200).

[0022] Since the two clamping blocks 19 firmly clamp and fix the rebar body 12 through the clamping protrusion, the two clamping blocks 19 cannot be pulled upward. The upward movement of the cylindrical block 13 will cause the two clamping blocks 19 to pull the two moving blocks 16 to tilt downward and stretch the spring 15. The two moving blocks 16 that tilt relative to each other will drive the two clamping blocks 19 to move relative to each other, thereby strengthening the clamping force on the rebar body 12 and ensuring the stability of the anchoring force test.

[0023] This anchoring force testing equipment features a pull-out self-locking structure. This structure tightens the clamping of the anchor cable during the pull-out process, ensuring a secure and stable connection between the anchor cable and the clamping structure. This effectively guarantees the reliability and stability of the anchoring force testing. Furthermore, the equipment boasts a simple structural design, convenient and easy connection operation, and stable and reliable connection fixation. Its performance meets the requirements for anchoring force testing.
