Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a non-destructive detection device for reinforced concrete structures. Background Art

[0002] Non-destructive testing of concrete plays a key role in ensuring the quality and safety of construction projects. It can accurately detect internal defects of concrete without destroying the structure, provide a scientific basis for construction and maintenance, effectively prevent safety accidents, and improve the scientificity and effectiveness of project quality management. Specifically, non-destructive testing technology can directly detect the strength, defect type and location inside the concrete. It is fast, accurate and highly sensitive. Compared with traditional testing methods, non-destructive testing can more comprehensively reflect the true condition of the concrete structure.

[0003] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: a common detection method is to use a rebound hammer for detection. There are two types of rebound hammers, one is manual calculation, and the other is an intelligent rebound hammer, which can automatically calculate and obtain rebound data. Although the detection is convenient, when testing components such as concrete columns, workers need to use climbing tools to climb up and test at different positions and heights, which may also lead to problems of incomplete and cumbersome detection.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4As shown, a nondestructive testing device for reinforced concrete structure includes a column 1, a slide rail mechanism 2 is provided at the top and bottom of the column 1, a plurality of support components 3 are provided at both ends of the slide rail mechanism 2, and a detection component 4 is provided between the support components 3 on both sides. The slide rail mechanism 2 includes two groups of components, and the two groups of components are respectively composed of two symmetrical semicircular slide rails 21. The interior of one of the semicircular slide rails 21 of the lower component is slidably connected to two lower double slider members 24, and the top of the lower double slider member 24 is fixed with a screw 241, and a handle 242 is fixed between the lower double slider members 24. The interior of one of the semicircular slide rails 21 of the upper component is slidably connected to two upper double slider members 23, and the bottom of the upper double slider member 23 is fixed with a screw 241. Screw holes 231 are drilled on the parts, and a ring 232 is fixed between the upper double slider members 23. The support assembly 3 includes an internal threaded tube 31, and a screw 2 32 is fixed on the top of the internal threaded tube 31. The detection assembly 4 includes an outer plate 41, and slides 43 are provided at both ends of the outer plate 41 close to the column 1. Two support rods 42 are fixed on the end of the slide 43 close to the outer plate 41, and the ends of the support rods 42 away from the slide 43 are respectively fixed to the side walls close to the outer plate 41. An electric telescopic rod 44 is fixed to the side wall of the outer plate 41 between the slides 43, and an intelligent rebound tester 45 is provided at the telescopic end of the electric telescopic rod 44. A ring 2 46 is fixed on the side of the outer plate 41 away from the electric telescopic rod 44, and a pull rope 5 is provided on the ring 2 46.

[0022] Specifically, bolt assemblies 22 are provided at both ends of the bottom between the two adjacent semicircular slide rails 21 , and the two semicircular slide rails 21 are detachably connected by the bolt assemblies 22 , so as to facilitate the installation of the slide rail mechanism 2 on the column 1 .

[0023] Specifically, the slide cylinders 43 are respectively sleeved on the outer walls of the internally threaded tubes 31 and slidably connected thereto, so that the detection assembly 4 has verticality when being raised or lowered.

[0024] Specifically, the second screw rod 32 of the lower support assembly 3 is inserted into the bottom of the internal threaded tube 31 of the upper support assembly 3 and is threadedly connected thereto, so that the adjacent support assemblies 3 are assembled.

[0025] Specifically, screw 1 241 is inserted into the internal threaded tube 31 at the matching position and threadedly connected thereto, and screw 2 32 of the upper support assembly 3 is inserted into the screw hole 231 and threadedly connected thereto, so that the support assembly 3 and the slide rail mechanism 2 can be assembled.

[0026] Specifically, the end of the pull rope 5 away from the ring 2 46 is connected to the ring 1 232. When the end of the pull rope 5 away from the ring 2 46 is pulled down, the support rod 42 slides upward on the internal threaded tube 31, and the smart rebound instrument 45 rises. After the pull rope 5 is slowly paid out, the smart rebound instrument 45 descends.

[0027] Working principle: The semicircular slide rail 21 is sleeved on the top and bottom ends of the column 1 and fixed by the bolt assembly 22. The adjacent support assemblies 3 are assembled by threading the screw rod 2 32 with the internal threaded tube 31. The threaded connection between the screw rod 1 241 and the internal threaded tube 31 and the threaded connection between the screw rod 2 32 and the screw hole 231 enable the support assembly 3 to be assembled with the slide rail mechanism 2. During the inspection, the electric telescopic rod 44 drives the intelligent rebound tester 45 to move toward one end close to the column 1, and makes the intelligent rebound tester 45 press against the column 1 and perform a rebound test. After the test, the electric telescopic rod 44 is recovered, and the data is stored in the smart rebound tester 45. The smart rebound tester 45 is a public and mature existing technology. Its internal components and principles will not be described in detail in this application. When adjusting the detection height, the pull rope 5 is pulled down away from one end of the ring 2 46, so that the support rod 42 slides upward on the internal threaded tube 31, and the smart rebound tester 45 rises. After slowly paying out the pull rope 5, the smart rebound tester 45 descends, holding the handle 242 and moving it left and right, so that the lower double slider 24 can slide in the semicircular slide rail 21, so that the smart rebound tester 45 can rotate around the column 1, thereby achieving a comprehensive detection effect.
