[0035] The working principle of the plate strength detection device for construction engineering of the present invention is as follows:

[0036] Step 1: During placement testing, the construction project board is first cut, and then placed on the testing position on the upper surface of the bottom plate 8, and the bottom plate 8 is used to support the construction project board.

[0037] Step 2: During the top cross detection, the sleeve plate 1 is supported by the support block 6, and the controller 7 starts the electric cylinder 2, which pushes the sleeve plate 3 downward, and the sleeve plate 3 slides down along the outer wall of the plurality of guide columns 5. At the same time, the sleeve plate 3 drives the cross bar 4 downward, and the cross bar 4 is pressed on the upper surface of the plate used for construction engineering. At the same time, the bottom plate 8 supports the plurality of guide columns 5, and the guide columns 5 support the support block 6 to provide support force, thereby increasing the stability of the support block 6. At the same time, the sleeve plate 3 enables the cross bar 4 to perform pressure detection operation on the upper surface of the plate used for construction engineering.

[0038] Step 3: When performing synchronous detection of the front and rear, the controller 7 starts the reduction motor 11, and the reduction motor 11 drives the screw 10 to rotate inside the slide frame 9. The screw 10 drives the two sleeves 13 to approach each other under the action of the thread. The two sleeves 13 respectively drive the two linkage bars 14 to approach each other. The linkage bar 14 drives the connection block 15 to move backward, and the other connection block 15 moves forward, so that the connection block 15 drives the pressure bar 16 to move backward, and the pressure bar 16 drives multiple pressure columns 17 to squeeze in front of the board used for the construction project, and the pressure bar 16 drives the support block 18 to move backward. At the same time, the support block 18 drives the corner pressure bar 19 to squeeze at the front corner position of the board used for the construction project, and the multiple pressure columns 17 on the other pressure bar 16 can squeeze at the back position of the board used for the construction project, so that the pressure detection of the front and back and corner positions of the board used for the construction project is realized. When the torque sensor 12 senses the torque of the screw 10, when the torque value sensed by the torque sensor 12 is the same as the value set by the controller 7, the reduction motor 11 is turned off by the controller 7.

[0039] Step 4: During the left and right synchronous detection, the sleeve plate 3 provides support force to the support bar 21, the support bar 21 provides support force to the support frame 20, the support frame 20 supports the slide bar 22, and the pressure cylinder 25 pushes the sliding sleeve block 23 to move up, and the sliding sleeve block 23 slides up along the outer wall of the slide bar 22. At the same time, the sliding sleeve block 23 slides up along the inner wall of the support frame 20, and the sliding sleeve block 23 makes the two hinge blocks 26 move up synchronously, the hinge block 26 drives the hinge shaft 27 to move up, and the hinge shaft 27 makes the top of the sleeve shaft 28 move up.

[0040] At the same time, the sleeve shaft 28 drives the connecting shaft 29 to move to the left, and the other connecting shaft 29 moves to the right. The connecting shaft 29 drives the concave sleeve block 30 to move to the left. The concave sleeve block 30 moves to the left along the inner wall of the guide frame 32. At the same time, the concave sleeve block 30 moves to the left along the outer wall of the sliding column 31. The concave sleeve block 30 drives the pressing strip 33 to move to the left. The pressing strip 33 drives multiple test strips 34 to move to the left. The test strips 34 are pressed on the right side of the plate used for the construction project, and the multiple test strips 34 on the other pressing strip 33 can be pressed on the left side of the plate used for the construction project. In this way, the left and right sides of the plate used for the construction project are synchronously detected. When the pressure value sensed by the pressure sensor 24 is the same as the detection value set by the controller 7, the pressure cylinder 25 is closed by the controller 7. It can be checked whether the plate used for the construction project has a disconnection problem.
