Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a testing device for reinforced concrete frame columns. Background Technology

[0002] As an important load-bearing component in building structure, the stability and reliability of reinforced concrete frame columns are crucial to the safety of the entire building. Therefore, conducting experimental research on reinforced concrete frame columns to evaluate their mechanical properties, durability, and seismic performance is an important part of building structural design and construction.

[0003] Especially when conducting seismic tests on reinforced concrete columns, traditional reinforced concrete column tests are not convenient for visually comparing reinforced concrete columns cast with different mix proportions. In addition, the test personnel often need to stay away from the test equipment to prevent injury. This also makes it difficult for the test personnel to observe the details of the test up close.

[0004] To address the aforementioned issues, this utility model document proposes a test device for reinforced concrete frame columns. Utility Model Content

[0005] This utility model provides a test device for reinforced concrete frame columns, which solves the shortcomings of the prior art, especially when conducting seismic tests on reinforced concrete columns. Traditional reinforced concrete column tests are not convenient for direct comparison of reinforced concrete columns with different mix proportions, and the test personnel often need to stay away from the test device to prevent injury. This also makes it inconvenient for test personnel to observe the details of the test at close range.

[0006] This utility model provides the following technical solution:

[0007] A test device for reinforced concrete frame columns includes a base, a swaying seat is provided on the top of the base, a first pit and a second pit are provided on the top of the swaying seat, and reinforced concrete columns are provided inside the first pit and the second pit.

[0008] A swaying mechanism, located at the top of the base, is used to simulate the swaying caused by an earthquake;

[0009] The protective mechanism, located on one side of the base, is used to protect test personnel who are observing at close range.

[0010] In one possible design, the wobbling mechanism includes a mounting plate, hydraulic cylinders, rolling grooves, mounting slots, and rollers. The bottom of the mounting plate is fixedly connected to the top of the base. The output ends of the plurality of hydraulic cylinders are fixedly connected to one side of the wobbling seat, and the other ends of the plurality of hydraulic cylinders are fixedly connected to one side of the mounting plate. Two rolling grooves are formed on the top of the base, and two mounting slots are formed on the bottom of the wobbling seat. Rotating shafts are fixedly connected inside the plurality of rollers, and the two ends of the plurality of rotating shafts are respectively rotatably connected to the inner walls of the two mounting slots.

[0011] In one possible design, the multiple rollers are divided into two groups, and the two groups of rollers are respectively arranged inside two rolling grooves for rolling inside the two rolling grooves. A partition is fixedly connected to the top of the rocking seat, and triangular seats are fixedly connected to both sides of the partition. The bottom of the two triangular seats is fixedly connected to the top of the rocking seat.

[0012] In one possible design, the protective mechanism includes a fixed plate, a connecting plate, an extension plate, a controller, an observation frame, and an observation window. One side of the fixed plate is fixedly connected to one side of the base. The bottom of the connecting plate is fixedly connected to the top of the fixed plate. The bottom of the extension plate is fixedly connected to the bottom inner wall of the observation frame. The bottom of the observation frame is fixedly connected to the top of the connecting plate. The controller is fixedly connected to one side of the extension plate. The observation window is opened on one side of the observation frame.

[0013] In one possible design, two recording frames are fixedly connected to one side of the connecting plate, and each of the two recording frames has a label slot on one side for placing detailed information of the corresponding reinforced concrete column.

[0014] In one possible design, the controller is electrically connected to multiple hydraulic cylinders to facilitate the control of the operation of the multiple hydraulic cylinders.

[0015] In this application, before conducting the test, the test personnel need to scale up or down the reinforced concrete column proportionally and install it in the first and second foundation pits of the swaying seat, respectively, ensuring that it is firmly fixed. Then, the test personnel start the hydraulic cylinder through the controller. When the controller issues a command, the hydraulic cylinder starts working, and its piston rod extends or retracts, thereby pushing or pulling the swaying seat to produce a swaying effect simulating an earthquake. To ensure that the swaying seat can sway smoothly and steadily, a rolling groove is opened at the top of the base, and rollers are installed at the bottom of the swaying seat. The rollers are rotatably connected to the inner walls of the mounting groove on both sides via a rotating shaft. When the swaying seat sways, the rollers roll in the rolling groove, which helps to reduce frictional resistance and improve the smoothness and stability of the swaying. A partition is fixedly connected to the top of the swaying seat, and triangular seats are fixedly connected to both sides of the partition, thereby preventing the swaying seat from being penetrated. When one reinforced concrete column collapses, it affects another. During the test, an observation frame is fixed to the top of the connecting plate, and an observation window is opened on one side of the observation frame, providing the test personnel with a window to observe the test process of the reinforced concrete column. This allows the test personnel to safely observe the test process within the test area. Two recording frames are fixedly connected to one side of the connecting plate to store detailed information about the corresponding reinforced concrete column, such as the specimen's dimensions, material, and reinforcement details. This information helps the test personnel better understand the specimen and conduct analysis. The controller is electrically connected to multiple hydraulic cylinders, allowing the test personnel to easily control the working status of the hydraulic cylinders, such as starting, stopping, and adjusting the amplitude and frequency of the shaking. This ensures that the test process can be carried out according to the predetermined plan and improves the accuracy and controllability of the test.

[0016] In this utility model, the reinforced concrete frame column test device can simulate earthquake shaking of various degrees through a shaking mechanism, thereby facilitating the comparison of test results of two reinforced concrete columns with different mix ratios, thus enhancing the practicality of the device.

[0017] In this utility model, the reinforced concrete frame column test device, through the protective mechanism, can provide a safe observation space for the test personnel, thereby facilitating the test personnel to observe the subtle changes of the reinforced concrete column during the shaking process;

[0018] In this invention, the swaying mechanism simulates a real earthquake environment to enable testing of reinforced concrete columns with two different mix ratios, while the protective mechanism ensures the safety of the test personnel and facilitates observation and recording, thus ensuring the smooth progress of the test and the accuracy of the results.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please refer to Figures 1-4 A test device includes: a base 1, a swaying seat 2 on the top of the base 1, a first pit 3 and a second pit 4 on the top of the swaying seat 2, and reinforced concrete columns 5 inside the first pit 3 and the second pit 4, so that the test personnel can enlarge or reduce the reinforced concrete column 5 to be tested proportionally and install it in the first pit 3 and the second pit 4 of the swaying seat 2 respectively for testing.

[0028] A swaying mechanism, located on the top of the base 1, is used to simulate the swaying caused by an earthquake. The swaying mechanism includes a mounting plate 8, hydraulic cylinders 9, rolling grooves 10, mounting slots 11, and rollers 12. The bottom of the mounting plate 8 is fixedly connected to the top of the base 1. The output ends of the multiple hydraulic cylinders 9 are fixedly connected to one side of the swaying base 2, and the other ends of the multiple hydraulic cylinders 9 are fixedly connected to one side of the mounting plate 8. Two rolling grooves 10 are formed on the top of the base 1, and two mounting slots 11 are formed on the bottom of the swaying base 2. Rotating shafts 20 are fixedly connected inside the multiple rollers 12, and the two ends of the multiple rotating shafts 20 are rotatably connected to the two mounting slots 11. On the inner walls of both sides of the base 1, when the test personnel start the hydraulic cylinder 9 through the controller 17, the controller 17 issues a command, the hydraulic cylinder 9 starts to work, its piston rod extends or retracts, thereby pushing or pulling the swaying seat 2, so as to produce a shaking effect simulating an earthquake. In order to ensure that the swaying seat 2 can shake smoothly and steadily, the device has a rolling groove 10 on the top of the base 1 and a roller 12 installed at the bottom of the swaying seat 2. The roller 12 is rotatably connected to the inner walls of both sides of the mounting groove 11 through the rotating shaft 20. When the swaying seat 2 shakes, the roller 12 will roll in the rolling groove 10, which helps to reduce frictional resistance and improve the smoothness and stability of the shaking.

[0029] A protective mechanism, located on one side of the base 1, is used to protect test personnel observing at close range. The protective mechanism includes a fixing plate 13, a connecting plate 14, an extension plate 16, a controller 17, an observation frame 18, and an observation window 19. One side of the fixing plate 13 is fixedly connected to one side of the base 1. The bottom of the connecting plate 14 is fixedly connected to the top of the fixing plate 13. The bottom of the extension plate 16 is fixedly connected to the inner wall of the bottom side of the observation frame 18, and the bottom of the observation frame 18 is fixedly connected to the top of the connecting plate 14. The controller 17 is fixedly connected to one side of the extension plate 16. The observation window 19... 9 is opened on one side of the observation frame 18, so that when the observation frame 18 is fixed to the top of the connecting plate 14, the observation window 19 is opened on one side of the observation frame 18, thus providing the test personnel with a window to observe the test process of the reinforced concrete column 5. This allows the test personnel to safely observe the test process in the test area. Two recording frames 15 are fixedly connected to one side of the connecting plate 14 for storing detailed information of the corresponding reinforced concrete column 5, such as the size, material, and reinforcement of the specimen. This information helps the test personnel to better understand the specimen and conduct analysis.

A partition 6 is fixedly connected to the top of the shaking seat 2, and triangular seats 7 are fixedly connected to both sides of the partition 6. The bottom of the two triangular seats 7 is fixedly connected to the top of the shaking seat 2, thereby preventing the collapse of one reinforced concrete column 5 from affecting the other reinforced concrete column 5.

[0035] Two recording frames 15 are fixedly connected to one side of the connecting plate 14. Each of the two recording frames 15 has a label slot on one side for placing detailed information of the corresponding reinforced concrete column 5, thereby enhancing the practicality of the device.

[0036] The controller 17 is electrically connected to multiple hydraulic cylinders 9 to facilitate the control of the operation of multiple hydraulic cylinders 9. This allows the test personnel to conveniently control the working state of the hydraulic cylinders 9 through the controller 17, such as starting, stopping, adjusting the amplitude and frequency of shaking, etc. This ensures that the test process can be carried out according to the predetermined plan and improves the accuracy and controllability of the test.
