Description

Technical Field

[0001] The utility model relates to the technical field of ribbed steel bars, and particularly relates to a ribbed steel bar convenient for measuring bending. Background Art

[0002] Ribbed steel bars are the common name for hot-rolled ribbed steel bars and are essential materials in the construction industry. Therefore, their performance needs to be qualified before they can be put into use. When testing the performance of ribbed steel bars, it is usually necessary to test the bending performance of the ribbed steel bars.

[0003] In order to facilitate the bending detection of ribbed steel bars, many improvements have been made to ribbed steel bars in the prior art. For example, the patent with the publication number CN216560085U discloses a ribbed steel bar convenient for measuring bending. To solve the problem that when measuring the bending of existing ribbed steel bars, the suspension ropes are prone to deviation and the positions are not uniformly fixed, resulting in inconvenient measurement, a ribbed steel bar center body is arranged on one side of the ribbed steel bar body. Threads are arranged on the surfaces of both the ribbed steel bar center body and the ribbed steel bar body, and the threads, the ribbed steel bar center body, and the ribbed steel bar body are all of one-piece structure. A connecting cylinder is arranged between the ribbed steel bar center body and the ribbed steel bar body, and the ribbed steel bar center body, the connecting cylinder, and the ribbed steel bar body are all of one-piece structure. A limiting rope is arranged outside the connecting cylinder, a suspension rope is arranged at the upper end of the limiting rope, a limiting hole cylinder is arranged on one side of the connecting cylinder, and a fixing hole cylinder is arranged on the other side of the connecting cylinder. The limiting hole cylinder and the fixing hole cylinder are of one-piece structure with the ribbed steel bar body.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In the above comparative document, the limiting rope is sleeved in the measuring groove, and the ribbed steel bar during bending is limited by the limiting rope. In actual operation, when testing the bending of ribbed steel bars, a hydraulic press is usually used to press down the middle position of the ribbed steel bar to be tested. When the quality of the ribbed steel bar is unqualified, the ribbed steel bar to be tested will be bent to a certain extent and then break. When breaking, a large force will be generated, and the broken ribbed steel bar will break away from the limiting rope, which may accidentally injure the testing personnel and there are certain safety hazards. Therefore, it is urgent in this field to improve the ribbed steel bar convenient for measuring bending to solve the defects of the prior art. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a ribbed steel bar convenient for measuring bending, which improves the safety when testing the bending of the ribbed steel bar body and facilitates the connection between the connecting thread cap and the ribbed steel bar body by the testing personnel.

One end of the push rod abuts against the side surface of the clamping platform. A baffle is fixedly connected to the end of the push rod away from the clamping platform. A spring sleeved on the side surface of the push rod is fixedly connected between the baffle and one side of the fixing plate.

[0010] Preferably, an elastic sheet is provided between the opposite side walls in the clamping frame, and the elastic sheet is elastic.

[0011] Preferably, plug-in blocks are fixedly connected to both ends of the elastic sheet, and plug-in grooves adapted to the plug-in blocks are provided on the opposite side walls in the clamping frame.

[0014] Aiming at the deficiencies of the prior art, the present utility model provides a deformed steel bar facilitating bending measurement, overcoming the deficiencies of the prior art. The beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, a connecting rope is tied to the connecting ring, and the other end of the connecting rope is tied to the frame of the hydraulic device. The connecting threaded cap is threadedly connected to the thread position.

[0027] Example 1

[0028] Please refer to Figures 1-5 , a deformed steel bar that is convenient for measuring bending, including a deformed steel bar body 1. Connecting threaded nuts 2 are provided at both ends of the deformed steel bar body 1. Threaded teeth 3 adapted to the connecting threaded nuts 2 are provided at both ends of the deformed steel bar body 1. Connecting seats 4 are provided at one end of each of the two connecting threaded nuts 2. Connecting rings 5 are provided on the side of each of the two connecting seats 4 away from the connecting threaded nuts 2.

[0029] Specific implementation method in this embodiment: When it is necessary to perform a bending test on the deformed steel bar body 1, a connecting rope is tied to the connecting ring 5, and the other end of the connecting rope is tied to the frame of the hydraulic device. Thread tapping is performed on the outer sides of both ends of the deformed steel bar body 1 to be measured. The connecting threaded nut 2 is threadedly connected to the position of the threaded teeth 3. The deformed steel bar body 1 is horizontally placed on the detection table. The hydraulic device is started to press down on the middle part of the horizontally placed deformed steel bar body 1. If the deformed steel bar body 1 is of unqualified quality and is broken by the hydraulic device, the two broken sections of the deformed steel bar body 1 will not fly out of the detection device to cause harm to the detection personnel due to the restriction of the connecting rope, improving the safety during the bending test of the deformed steel bar body 1. At the same time, the connecting threaded nut 2 is threadedly connected to the threaded teeth 3, which is also convenient for the detection personnel to connect the connecting threaded nut 2 and the deformed steel bar body 1, and the connecting threaded nut 2 can be reused.

[0030] Example 2

[0031] Please refer to Figures 2-5 , this embodiment includes the above embodiment, and further includes: A U-shaped clamping frame 6 is fixedly connected to the side of each connecting ring 5. Both sides of the clamping frame 6 are elastic. A clamping groove 7 adapted to the clamping frame 6 is provided on the connecting seat 4. Clamping platforms 8 are fixedly connected to the side surfaces of both ends of the clamping frame 6. Clamping ports 9 adapted to the clamping platforms 8 are provided on the opposite side walls in the clamping groove 7. Through holes 10 communicating with the clamping groove 7 are provided on the opposite side surfaces of the connecting seats 4. Two symmetric fixing plates 11 are fixedly connected to one side of each of the two connecting seats 4. A push rod 12 passes through the fixing plate 11.

[0032] Specific implementation method in this embodiment: When performing a bending test on the deformed steel bar body 1, multiple connecting threaded nuts 2 can be prepared. The connecting threaded nuts 2 are connected to the deformed steel bar body 1 to be detected in advance. When it is necessary to detect the deformed steel bar body 1, the connecting ring 5 is inserted into the clamping groove 7 through the clamping frame 6. Since both ends of the clamping frame 6 are elastic, when the clamping table 8 moves to the clamping port 9, the clamping table 8 is clamped at the clamping port 9, which is convenient for the connecting ring 5 to be connected to the connecting seat 4. Since the connecting threaded nuts 2 are installed in advance and are connected to the connecting ring 5 during detection, the installation time of the connecting ring 5 during detection is reduced, thereby improving the efficiency of the bending test on the deformed steel bar body 1. After the bending test of the deformed steel bar body 1 is completed, by pressing the two baffles 13 in the opposite direction, the two push rods 12 move towards each other and squeeze the clamping table 8. When the clamping table 8 is separated from the clamping port 9, the connecting ring 5 can be separated from the connecting seat 4. Then, the deformed steel bar body 1 to be detected is connected to the connecting seat 4 through the clamping frame 6 again. When detecting, the connecting threaded nuts 2 at both ends of the deformed steel bar body 1 that has been detected are removed, saving time, and thereby improving the efficiency of the bending test on the deformed steel bar body 1.
