In this embodiment, the fixing fixture 200 mainly includes a chuck 210 and at least three jaws 220, the jaws 220 are uniformly distributed circumferentially around the axis of the chuck 210, and the jaws 220 are in linkage fit with each other, so that the jaws 220 can synchronously move along the radial direction of the chuck 210 to coaxially fix and clamp the concrete test block 600, so as to ensure that the axis of the concrete test block 600 coincides with the axis of the chuck 210.
The fixing clamp 200 further comprises a driving handle 230, the clamping jaw 220 can be controlled to move radially on the chuck 210 by rotating the driving handle 230, and the clamping force is convenient to control by manually adjusting the driving handle 230 to clamp the concrete test block 600, so that damage to the concrete test block 600 due to overlarge clamping force is avoided. Of course, the claw 220 may be driven by a motor (not shown), preferably a torque motor, as a driving source, so that effective fixing and clamping of the concrete test block 600 can be effectively ensured.
Further, the mounting frame 400 includes an annular bottom plate 410 and a side plate 430 extending vertically, the annular bottom plate 410 is coaxially disposed above the fixing clamp 200, the side plate 430 is fixedly disposed on the circumference of the annular bottom plate 410, and the annular bottom plate 410 and the side plate 430 together enclose the avoidance space. The annular bottom plate 410 has a center hole 420, and the concrete test block 600 held on the fixing jig 200 passes upward through the center hole 420 and protrudes into the avoidance space.
In the present embodiment, the side plates 430 are in a split arrangement, two side plates 430 are uniformly arranged at intervals in the circumferential direction of the annular bottom plate 410, and the side plates 430 are provided with long mating holes 440 penetrating in the radial direction of the annular bottom plate 410, and the long mating holes 440 extend in the vertical direction. The guide frame 450 mainly comprises an annular frame 460 and a matching protrusion 470, the annular frame 460 and the annular bottom plate 410 are coaxially arranged, the two matching protrusions 470 are uniformly arranged on the annular frame 460 at intervals, the matching protrusion 470 on the guide frame 450 is vertically guided and matched with the matching long hole 440 on the side plate 430, and therefore the guide frame 450 can vertically guide and move along the matching long hole 440 on the installation frame 400.

Further, two resiliometers 500 are also provided, guide holes (not shown in the figure) are provided on the fitting protrusions 470, the axes of the guide holes extend along the radial direction of the mounting frame 400, the resiliometers 500 are correspondingly guided and assembled in the guide holes one by one, and the axes of the resiliometers 500 are vertically directed to the axes of the mounting frame 400. Because the axis of the mounting frame 400 coincides with the axis of the fixing clamp 200, and the fixing clamp 200 coaxially clamps the concrete test block 600, the axis of the mounting frame 400 coincides with the axis of the concrete test block 600, so that the axis of the resiliometer 500 which is vertically directed to the axis of the mounting frame 400 also vertically directs to the axis of the concrete test block 600, that is, the resiliometer 500 is always vertical to the surface of the concrete test block 600, thereby effectively ensuring the detection precision of the resiliometer 500 to the concrete test block 600.
And when carrying out the rebound test to concrete test block 600, a plurality of resiliometers 500 of evenly distributed in circumference are in step roof pressure concrete test block 600, can make concrete test block 600 be in the stress balance state, avoid concrete test block 600 to produce moment of flexure and influence rebound testing result, can also survey the multiunit data in different positions simultaneously, improved detection efficiency, convenient to use has further improved the accuracy nature of rebound testing result.

In addition, at least three moving wheels 110 are uniformly arranged at the bottom of the base 100, so that the base 100 can drive the positioning mechanism to move freely synchronously, thereby facilitating the use of the device. If the force applied by the resiliometer 500 to the concrete test block 600 cannot make the concrete test block 600 in a balanced state, the base 100 will move, which indicates that the rebound detection result is inaccurate, and adjustment is needed, so that the detection accuracy is guaranteed.
The construction subject concrete structure inspection system of the present application is further described with reference to fig. 1 and 2 in conjunction with a specific use procedure.
In a first step, a cylindrical concrete test block 600 is drilled from a concrete member for rebound testing by the resiliometer 500.
And secondly, placing the concrete test block 600 in the center of the chuck 210, and driving the claw 220 to radially move by the driving handle 230 to coaxially and fixedly clamp the concrete test block 600. At this time, the upper end of the concrete block 600 passes through the center hole 420 of the annular bottom plate 410 and protrudes into the avoidance space on the mounting frame 400.
Third, the detection position is marked on the concrete test block 600, and the guide frame 450 is moved up and down to drive the resiliometer 500 to move up and down synchronously, so that the resiliometer 500 is aligned to the detection position of the concrete test block 600.
Fourth, the resiliometer 500 on the guide frame 450 is pushed to move along the radial synchronous guide of the mounting frame 400, and the rebound detection is performed on the concrete test block 600. The plurality of resiliometers 500 uniformly distributed around the axial line of the concrete test block 600 simultaneously apply a pushing force to the concrete test block 600, so that the stress of the concrete test block 600 in the circumferential direction is balanced, the occurrence of bending moment of the concrete test block 600 is avoided, and the accuracy of a rebound test result is ensured.
In the above process, since the positioning mechanism is disposed on the base 100, and the bottom of the base 100 is uniformly provided with at least three moving wheels 110, the positioning mechanism can move freely. If the resiliometer 500 around the concrete test block 600 cannot synchronously push the concrete test block 600 with the same force, the concrete test block 600 is unbalanced in stress and then drives the base 100 to move, so that the test personnel is prompted to detect that the result is inaccurate, the rebound test stroke of the resiliometer 500 is asynchronous, and the stroke of the resiliometer 500 needs to be adjusted and detected again.
