Description
Technical Field
[0001] The present application relates to the field of building steel structures, and in particular to a device for detecting the bearing strength of steel structures. Background Art
[0002] Steel structures are made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses, constructed from sections and plates. Rust removal and prevention processes include silanization, pure manganese phosphating, water washing and drying, and galvanizing. Components are typically connected using welds, bolts, or rivets. Architectural steel structures require strength testing before construction and use.
[0003] When conducting strength testing on existing building steel structures, it is impossible to accurately measure the load-bearing and compressive strength values of each point of the steel structure, which affects the accuracy of the testing structure.
[0004] For example, a device for testing the strength of a building steel structure. The main technical principle of this patent is to design a device for testing the strength of a building steel structure, use a pressure cone and a hydraulic cylinder to perform strength tests on multiple points on the steel structure, so that the pressure cone contacts the building steel structure on the electronic scale and applies pressure. The value of the pressure applied will be displayed on the scale display, thereby achieving accurate measurement. In addition, when the building steel structure is deformed, the movement of the hydraulic cylinder is stopped, and the value on the scale display at this time is recorded. The recorded value is the maximum range of pressure strength that the steel structure can withstand. The deformation process is intuitively displayed, which makes it convenient for staff to record the value in a timely manner.
[0005] The above-mentioned detection device cannot clamp and fix the steel structure to be detected, and is prone to sliding on the surface of the steel structure due to the small point of action, resulting in an unstable detection process. Summary of the Invention
[0006] In order to improve the stability of steel structure bearing strength testing, the present application provides a steel structure bearing strength testing device.
[0007] The present application provides a steel structure bearing strength detection device that adopts the following technical solution: A steel structure bearing strength detection device, comprising A box body, wherein a movable pressing platform is provided in the middle of the box body, and the movable pressing platform is driven to move vertically by a first driving member provided on the top of the box body, and a pressure hammer is provided at the bottom of the movable pressing platform, and the pressure hammer abuts against the steel structure and applies pressure to the steel structure; Support platforms are provided at the bottom of the box body, and two opposite platforms are provided along the inner side of the box body. The support platforms are provided on both sides of the upper surface of the base and avoid the movable pressing platform, and support the two ends of the steel structure through the support platforms; The positioning device is provided in two pieces and is respectively provided above the two support platforms for positioning the steel structure, including a first positioning member for positioning the side of the steel structure, the first positioning member is provided on both sides of the steel structure, including a limit plate fixedly connected to the support platform, a slider is provided at the bottom of the limit plate, a slide groove for the support platform to move the slider is provided, a bidirectional screw rod is provided inside the slide groove, and a hole is provided on the slider for the bidirectional screw rod to rotate, and the rotation of the bidirectional screw rod drives the two limit plates relative to each other to move closer to or away from each other; The sensing display device includes a pressure sensor arranged at the bottom of the pressure hammer and a display screen arranged outside the box, and the pressure sensor and the display screen are electrically connected.
[0008] By adopting the above technical solution, when testing the bearing strength of the steel structure, the steel structure is first placed on the support platform, and the two limit plates are driven closer to each other by rotating the bidirectional screw, the steel structure is clamped between the two limit plates, and the two sides of the steel structure are fixed. After the steel structure is fixed, the movable press plate is driven downward by the first driving member arranged on the top of the box, and the pressure hammer arranged under the movable press plate acts on the top of the steel structure. The pressure sensor processes the pressure information through the relevant controller and processor and displays it on the display screen, which is convenient for the experimental test personnel to record and observe the pressure information. By setting the positioning device to fix the steel structure, steel structures of different sizes can be fixed to prevent inaccurate measurement results due to sliding of the steel structure surface, thereby improving the stability of the steel structure bearing strength test.
[0009] Preferably, a buffer member is provided on the opposite side of the limiting plate, and the buffer member includes a buffer plate provided parallel to the limiting plate and a buffer spring provided between the buffer plate and the limiting plate.
[0010] By adopting the above technical solution, a buffer plate is set between the limit plates when the steel structure is clamped and fixed, and the buffer plate is directly in contact with the steel structure to avoid the limit plate from squeezing and deforming the steel structure when the steel structure is fixed. Through the set buffer plate, the buffer spring will remove excess force when the steel structure is clamped and fixed, avoiding inaccurate measurement results when measuring the steel structure, and further improving the stability of the steel structure during bearing strength testing.
[0011] Preferably, the positioning device also includes a second positioning member for fixing the top of the steel structure, the second positioning member includes a fixing plate connected to the inner wall of the box, a pressure plate arranged below the fixing plate, and a driving rod penetrating the fixing plate and connected to the pressure plate, the driving rod is a threaded rod, and a threaded hole is provided in the middle of the fixing plate for the driving rod to rotate, and the rotation of the driving rod can drive the pressure plate to move toward or away from the fixing plate.
[0012] By adopting the above technical solution, when the top of the steel structure is fixed by the second positioning member, the second positioning member needs to be adjusted due to the different sizes of the steel structures to be tested. By connecting the fixing plate to the inside of the box and adjusting the height of the pressure plate through the driving rod, the pressure plate is pressed on top of the steel structure to fix the steel structure. Steel structures of different sizes can be positioned, further improving the stability of the steel structure during bearing strength testing.
[0013] Preferably, the fixed plate can move along the height direction of the inner side of the box body, and a movable plate is provided on the side of the fixed plate close to the box body. A movable groove for the movable plate to move is started on the box body, and the width of the movable groove is equal to the width of the movable plate. A fixed groove connected to the movable groove is opened on one side of the movable groove, and multiple fixed grooves are provided along the length direction of the movable groove. The width of the fixed groove is equal to the width of the movable groove, and the height is the same as the thickness of the movable plate.
[0014] By adopting the above technical solution, in order to facilitate operation when rotating the driving rod, the length of the driving rod is limited. When the height of the pressure plate is adjusted by the driving rod, the adjusted height is less than the length of the driving rod, and an overly large steel structure cannot be fixed well. By setting a movable plate at the fixed plate, when fixing the height direction of the steel structure, the movable plate is first moved to a suitable height in the movable groove, and then the movable plate is placed in the fixed groove to fix the height of the fixed plate. After that, the pressure plate is adjusted by adjusting the driving rod, and steel structures of different sizes can be fixed in a wider range, thereby improving the stability of the steel structure during the bearing strength test.
[0015] Preferably, two movable plates are provided along the side of the fixed plate, and two groups of corresponding movable grooves and fixed grooves are provided.
[0016] By adopting the above technical solution, two groups of movable plates and corresponding movable grooves and fixed grooves are set. When the height of the fixed plate is adjusted by the movable plate, the fixed plate is more stable, thereby improving the stability of the top of the steel structure when it is fixed, and further improving the stability of the steel structure during bearing strength testing.
[0017] Preferably, a plurality of pressure hammers are provided, and a pressure sensor is provided at each pressure hammer.
[0018] By adopting the above technical solution, multiple pressure hammers are set to apply pressure to the steel structure, and strength tests can be performed on multiple points on the steel structure at the same time. The test data is transmitted to the display screen through the pressure sensor, thereby achieving the purpose of accurate measurement, overcoming the problem that the existing building steel structure cannot accurately measure the load-bearing and compressive resistance values of each point of the steel structure during strength testing.
[0019] Preferably, it further comprises a deformation measuring instrument, which is arranged inside the box and electrically connected to the display screen to monitor the deformation of the steel structure.
[0020] By adopting the above technical solution, when testing the bearing strength of the steel structure, the pressure hammer stops moving when the steel structure is deformed, and the pressure value at this time is recorded. The recorded value is the maximum range of pressure strength that the steel structure can withstand. There is a certain error in the deformation of the steel structure observed intuitively by the observer. By setting up a deformation measuring instrument to observe the deformation of the steel structure in real time, the observation result is more accurate and the measured bearing strength of the steel structure is more precise.
[0021] Preferably, the deformation measuring instrument is fixedly mounted on a mounting plate, and the height of the mounting plate is adjustable.
[0022] By adopting the above technical solution, the steel structure has different sizes and the pressure hammer presses at different heights. By adjusting the height of the mounting plate and then adjusting the height of the deformation measuring instrument, the deformation of the steel structure can be better measured.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When testing the bearing strength of a steel structure, first place the steel structure on the support platform, and drive the two limit plates closer to each other by rotating the bidirectional screw, clamp the steel structure between the two limit plates, and fix both sides of the steel structure. After the steel structure is fixed, the first driving member arranged on the top of the box drives the movable press plate to move downward, and the pressure hammer arranged under the movable press plate acts on the top of the steel structure. The pressure sensor processes the pressure information through the relevant controller and processor and displays it on the display screen, which is convenient for the experimental test personnel to record and observe the pressure information. By setting a positioning device to fix the steel structure, steel structures of different sizes can be fixed to prevent inaccurate measurement results due to sliding of the steel structure surface, thereby improving the stability of the steel structure during bearing strength testing. 2. When clamping and fixing the steel structure, a buffer plate is set between the limit plates, and the buffer plate is in direct contact with the steel structure to avoid the limit plates from squeezing and deforming the steel structure when fixing the steel structure. Through the provided buffer plate, the buffer spring will remove the excess force when clamping and fixing the steel structure, avoiding the phenomenon of inaccurate measurement results when measuring the steel structure, and further improving the stability of the steel structure during bearing strength testing; 3. When fixing the upper surface of the steel structure with the second positioning piece, the second positioning piece needs to be adjusted due to the different sizes of the steel structures to be tested. By connecting the fixing plate to the inside of the box and adjusting the height of the pressure plate through the driving rod, the pressure plate is pressed on the steel structure to fix the steel structure. Steel structures of different sizes can be positioned, further improving the stability of the steel structure during the bearing strength test; 4. By setting up multiple pressure hammers to apply pressure to the steel structure, strength tests can be performed on multiple points on the steel structure at the same time. The test data is transmitted to the display screen through the pressure sensor, thereby achieving the purpose of accurate measurement. This overcomes the problem that the existing building steel structure cannot accurately measure the load-bearing and compressive resistance values of each point of the steel structure during strength testing.
