Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and in particular relates to an anchor bolt performance detection device. Background Art

[0002] The utility model patent with the patent authorization announcement number CN219625252U discloses a test device for testing the shear resistance of building anchor bolts. The device includes two right-angle loading plates, a screw and an annular force sensor or a through-hole jack. The two right-angle loading plates are arranged at intervals, and the horizontal plates of the two right-angle loading plates are provided with through holes for inserting building anchor bolts. The screw connects the vertical plates of the two right-angle loading plates. The annular force sensor penetrates the screw and is located outside the vertical plate of any right-angle loading plate. Nuts are screwed into the two ends of the screw; or the through-hole jack is placed between the vertical plates of the two right-angle loading plates. By tightening the nut on the screw or starting the through-hole jack to apply the test load, the shear resistance of the anchor bolt can be tested. The device has a simple structure, low manufacturing cost, and flexible application scenarios. It is particularly suitable for shear resistance test of anchor bolts arranged adjacent to each other on large-scale planes such as the ground, wall, and ceiling bottom surface to ensure the anchoring quality of the anchor bolts. However, when the device is in use, it is not convenient to adjust the device to perform shear detection on any position of the anchor bolt. At the same time, when the anchor bolt breaks due to excessive force, the anchor bolt waste will fly away, which will pose a safety hazard. Summary of the invention

By rotating the support and the screw rod to make a threaded motion, the position of the bolt in the support sleeve can be adjusted, so that the device can perform shearing detection on any position of the anchor bolt.

[0011] Furthermore, a slide groove is provided inside the bottom plate, and the slide groove is slidably connected to the slide rod. The slide groove is provided to guide the movement of the slide rod.
