[0008] A detection component is disposed at the front end of the reinforcing bar body; wherein, the pushing component is used to push the tail end of the reinforcing bar body; and the detection component is used to perform strength detection on the head end of the reinforcing bar body.

[0009] Preferably, the pushing component includes a sliding track, a sliding block, and an adjusting plate.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the steel reinforcement detector for civil engineering is equipped with:

[0016] 1. Pushing structure: When the strength of the steel bar body needs to be tested, the steel bar body is first inserted through the inside of the through groove and the tail end of the steel bar body is placed inside the first clamping block. Then, the fastening bolt is rotated to fix the second clamping block on the upper end of the first clamping block and fix the tail end of the steel bar body. After the steel bar body is fixed, the servo motor is run and the output end of the servo motor rotates 180°, thereby driving the gear to rotate and causing the rack connected on the outside to move forward, thereby pushing the steel bar body connected at the upper end forward along the inside of the through groove for a certain distance.

[0017] 2. Testing Structure: After the first end of the rebar is pushed to the outside of the channel, the hydraulic rod is activated, causing the output end of the hydraulic rod to drive the extrusion plate downward. The downward movement of the extrusion plate will extrude the first end of the rebar at the lower end. When the hardness of the rebar is insufficient, its first end will bend, which will then extrude into the pressure sensor at the lower end. When the pressure sensor senses the pressure, it can be determined that the hardness of the rebar is insufficient. After the testing of the foremost part of the rebar is completed, the pushing component is activated again, which can push the rebar forward a certain distance again, thereby achieving the effect of testing the overall strength of the rebar.

[0018] Furthermore, when the hydraulic rod drives the extrusion plate downward, the auxiliary rods on the left and right sides of the extrusion plate will provide auxiliary support for the extrusion plate, thereby improving the stability of the extrusion plate in extruding the steel bar body.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a steel reinforcement detector for civil engineering, comprising:

[0027] Example 1: As Figures 1-4 The present invention provides a technical solution: a rebar detector for civil engineering, comprising: a base 1, with a positioning frame 2 fixedly installed on the upper end of the base 1; a through groove 3, which is formed inside the positioning frame 2; a rebar body 4, which penetrates the inside of the through groove 3; a pad 7, which is fixedly installed inside the through groove 3; a pushing component 5, which is disposed at the tail end of the rebar body 4; and a detection component 6, which is disposed at the front end of the rebar body 4.

[0028] The pushing component 5 includes a sliding rail 501, a sliding block 502, and an adjusting plate 503. The sliding rail 501 is fixedly installed on the left and right sides of the positioning frame 2, and the sliding block 502 is slidably connected to the inner side of the sliding rail 501. The two ends of the adjusting plate 503 are respectively connected to the sliding block 502. The pushing component 5 also includes a first clamping block 504, a second clamping block 502, and a fastening bolt 506. The first clamping block 504 is fixedly installed on the upper end of the adjusting plate 503, and the upper end of the first clamping block 504 is connected to the second clamping block 502 by the fastening bolt 506. Two clamping blocks 505, and the first clamping block 504 and the second clamping block 505 are viewed from the front as an arc-shaped structure; the pushing component 5 also includes a servo motor 507, a gear 508 and a rack 509. The servo motor 507 is fixedly mounted on the upper end of the base 1, and the output end of the servo motor 507 is fixedly connected to the gear 508. The gear 508 is meshed with the rack 509 on the outside, and the rack 509 is fixedly mounted on the bottom of the adjusting plate 503; the output end of the servo motor 507 is configured to perform a precise 180° rotational motion each time it is driven;

[0029] When the strength of the steel bar body 4 needs to be tested, the steel bar body 4 is first inserted through the inside of the through groove 3 and the tail end of the steel bar body 4 is placed inside the first clamping block 504. Then, the fastening bolt 506 is rotated to fix the second clamping block 505 on the upper end of the first clamping block 504, thus fixing the tail end of the steel bar body 4. After the steel bar body 4 is fixed, the servo motor 507 is run. The output end of the servo motor 507 rotates 180°, thereby driving the gear 508 to rotate. This causes the rack 509, which is meshed with the outer side of the gear 508, to move forward, thereby pushing the steel bar body 4 connected at the upper end forward a certain distance along the inside of the through groove 3.

[0030] Example 2: Figures 1-3 , Figure 5 The present invention provides a technical solution: a rebar detector for civil engineering, which discloses that: the detection component 6 includes a positioning frame 601, a pressure sensor 602, and a battery 603. The positioning frame 601 is fixedly installed on the upper end of the base 1, and the pressure sensor 602 is fixedly installed on the top of the positioning frame 601. The battery 603 is fixedly installed on the upper end of the positioning frame 2, and the battery 603 is electrically connected to the pressure sensor 602; the detection component 6 also includes a support frame 604 and a hydraulic rod 60 5.

Auxiliary spring 608 is connected between auxiliary rod 607 and support frame 604.

[0031] When the first end of the reinforcing bar body 4 is pushed to the outside of the through groove 3, the hydraulic rod 605 is activated, causing the output end of the hydraulic rod 605 to drive the extrusion plate 606 downward. The downward movement of the extrusion plate 606 will extrude the first end of the reinforcing bar body 4 at the lower end. When the hardness of the reinforcing bar body 4 is insufficient, its first end will bend, which will extrude the pressure sensor 602 at the lower end. When the pressure sensor 602 senses the pressure, it can be determined that the hardness of the reinforcing bar body 4 is insufficient. After the front part of the reinforcing bar body 4 has been tested, the pushing component 5 is activated again, which can push the reinforcing bar body 4 forward again, thereby achieving the effect of testing the overall strength of the reinforcing bar body 4. When the hydraulic rod 605 drives the extrusion plate 606 downward, the auxiliary rods 607 on the left and right sides of the extrusion plate 606 will provide auxiliary support for the extrusion plate 606, thereby improving the stability of the extrusion plate 606 in extruding the reinforcing bar body 4.
