[0002] A shear force detection device is a device used to detect how much shear force an object can withstand. It is often used in the construction industry. For shear force detection of beams, the existing technology uses a shear force detection device to test the shear force of building load-bearing beams so as to effectively detect unqualified materials used in building beams.

[0003] The existing building beam shear force detection device requires manual placement of the beam into the detection device when performing shear force detection on the beam, and can only detect beams of fixed sizes, but cannot detect beams of different sizes, and thus cannot measure the shear force of beams of different sizes. Therefore, we propose a building load-bearing beam shear force detection device. Utility Model Content

[0011] Furthermore, an inclined plate is fixed to the top of the bottom plate near one end of the push plate.

[0012] The beneficial effects of the present utility model are as follows: by arranging support rods, base plates, pushing devices, detection devices, clamping devices, etc., when in use, the beam is placed on the inclined plate, the hydraulic rod is started, and the hydraulic rod drives the second connecting plate to move, so that the rack drives the gear to rotate, and the U-shaped plate rotates 90 degrees clockwise.
