Description
Technical Field
[0001] The utility model relates to the technical field of steel structure strength detection, in particular to strength detection equipment for steel structure building reinforcement. Background Art
[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. At present, during the bending test of steel structures, two clamps are usually required to clamp and fix the two ends of the steel structure. However, the existing clamps are fixed. When the detection device applies pressure to the center of the steel structure, the two ends of the steel structure will flip inward and shrink. The clamp will be subjected to great pressure when the steel structure shrinks, thereby reducing the use of the clamp.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-5 , the utility model provides an embodiment: a strength detection device for steel structure building reinforcement, including a detection device 1;
[0025] Two groups of fixing plates 2 are symmetrically installed on the front and rear sides of the detection device 1. Through holes 3 are opened in the four groups of fixing plates 2. The lower sides of the four groups of fixing plates 2 are flush with the lower side of the detection device 1. A control component 4 is installed on the upper end of the detection device 1. A first hydraulic rod 5 is installed on the upper end of the detection device 1. A detection head 6 is installed on the lower end of the first hydraulic rod 5. A fixing frame 8 is symmetrically installed in the front and rear of the detection device 1. Clamping components are installed on both the left and right ends of the two groups of fixing frames 8. The device clamps and fixes the steel frame or steel plate through the clamping component, and then the first hydraulic rod 5 drives the detection head 6 to press the center of the steel frame or steel plate, so as to detect the strength of the steel frame or steel plate;
[0026] Furthermore, the clamping assembly includes two groups of slide grooves 9, which are symmetrically arranged in two groups of fixed frames 8. Slide blocks 10 are installed in both groups of slide grooves 9, and rotating shafts 11 are rotatably installed in both groups of slide blocks 10. A clamp 12 is fixedly installed between the two groups of rotating shafts 11. Two groups of second hydraulic rods 13 are installed on the upper end of the clamp 12, and pressure plates 14 are installed on the lower ends of the two groups of second hydraulic rods 13. This structure drives the pressure plates 14 to fix the steel frame or steel plate in the clamp 12 through the two groups of second hydraulic rods 13. When the first hydraulic rod 5 drives the detection head 6 to press the steel frame or steel plate, the two ends of the steel frame or steel plate are tilted and drive the clamp 12 to rotate on the two groups of slide blocks 10 through the two groups of rotating shafts 11, so that the clamp 12 changes with the bending and tilting of the two ends of the steel frame or steel plate.
[0027] Furthermore, the inner wall of the slide groove 9 and the slider 10 are both T-shaped, and the rotating shaft 11 and the clamp 12 are both made of titanium alloy. This structure, based on the shape of the interior of the slide groove 9 and the slider 10, ensures that the slider 10 will not fall off when sliding in the slide groove 9, and based on the material of the rotating shaft 11 and the clamp 12, the rotating shaft 11 and the clamp 12 have a certain strength to prevent the clamp 12 and the rotating shaft 11 from breaking.
[0028] Furthermore, an observation window 7 is provided on the front side of the detection device 1. The observation window 7 is transparent and is located in front of the detection head 6. This structure checks the bending condition of the steel frame or steel plate in the detection device 1 through the observation window 7 to avoid excessive pressure on the steel frame or steel plate.
[0029] Furthermore, anti-skid pads 15 are glued to the upper inner wall of the clamp 12 and the lower side of the pressing plate 14. This structure increases the tightness of clamping the two ends of the steel frame or steel plate through the anti-skid pads 15 on the upper inner wall of the clamp 12 and the lower side of the pressing plate 14.
[0030] Furthermore, strong springs 17 are installed in the four groups of slide grooves 9, and the four groups of strong springs 17 are fitted with the four groups of sliders 10. This structure resets the sliders 10 when they slide through the strong springs 17 and increases the resistance of the sliders 10 when they slide.
[0031] Furthermore, the two groups of anti-skid pads 15 are both made of rubber material, and the two groups of anti-skid pads 15 are arranged opposite to each other. This structure is low-cost and easy to replace due to long-term wear based on the material of the anti-skid pads 15.
[0032] Furthermore, torsion springs 16 are installed in the two sets of sliders 10 , and the two sets of torsion springs 16 are connected to the two sets of rotating shafts 11 .
[0033] Working principle: When testing the strength of steel frames or steel plates, Figure 3 , Figure 4 and Figure 5 As shown, the two ends of the steel frame or steel plate are inserted into the two sets of clamps 12, and the two sets of second hydraulic rods 13 on the two sets of clamps 12 drive the two sets of pressing plates 14 to clamp and fix the steel frame or steel plate. After the steel frame or steel plate is fixed, the first hydraulic rod 5 is started, and the first hydraulic rod 5 drives the detection head 6 to press toward the center of the steel frame or steel plate. When the steel frame or steel plate is pressed and bent, it drives the two sets of tilting. When the two ends of the steel frame or steel plate tilt, it drives the two sets of clamps 12 to rotate on the slider 10 through the rotating shaft 11, so that the two sets of clamps 12 are adapted to the warping of the two ends of the steel frame or steel plate. The tilting of the steel frame or steel plate drives the two sets of clamps 12, the four sets of rotating shafts 11 and the four sets of sliders 10 to slide close to each other in the slide groove 9, so as to avoid damage to the two sets of clamps 12 caused by the tilting of the steel frame or steel plate. When the steel frame or steel plate is removed, the four sets of sliders 10 and the two sets of clamps 12 are slid and reset under the action of the restoring force of the strong spring 17, and the two sets of clamps 12 and the four sets of rotating shafts 11 are reset under the torsion of the four sets of torsion springs 16, which is convenient for use on the lower side. The above is the entire working principle of the utility model.
