When the detection piece is deformed, the base can be moved closer to the middle position through the sliding component, and the bracket can be rotated following the deformation direction of the detection piece through the rotating component, thereby avoiding affecting the detection result of the detection piece and improving the accuracy of steel structure strength detection.

[0030] Working principle: A device for detecting the connection strength of a steel structure of a house. The detection piece is placed in the rectangular holes 603 of the two fixing mechanisms 6, and the electric push rod 609 is started to extend, so that the upper pressure plates 607 on both sides are driven to descend through the two U-shaped rods 606. The upper pressure plate 607 and the lower pressure plate 604 on the same side are brought close to each other to realize the fixing column of the detection piece. The hydraulic cylinder 4 is started to descend. When the two triangular plates 11 are close to the detection piece, under the action of the triangular plates 11, the two L-shaped card plates 10 are moved away from each other and the spring 901 is compressed until the first pressure sensors 16 of the two L-shaped card plates 10 descend to the bottom of the detection piece. When the hydraulic cylinder 4 is started to shrink, the two L-shaped card plates 10 are pressed against the bottom of the detection piece. To realize pulling of the detection piece, the pressure is detected by the first pressure sensor 16. When the detection piece bends, since both the upper pressure plate 607 and the lower pressure plate 604 can rotate, the two sliding plates 602 can approach each other, thereby driving the two U-shaped rods 606 to approach each other, so that the detection piece will not fall off from the fixing mechanism 6 when it is deformed. When the hydraulic cylinder 4 is started to extend, the detection piece is squeezed by the second pressure sensor 17 at the bottom of the strip plate 8. The strength of the detection piece can be detected by the second pressure sensor 17, and the pull rod 15 is pulled. Under the action of the triangular hole 14 and the cylindrical protrusion 12, the two L-shaped clamping plates 10 move away from each other, so that the detection piece is taken away.
