During the assembly of lightweight steel metal roof, clamps or anchor bolts are often used for fixed connection to form support nodes. However, after installation, it is often necessary to test the pull-out bearing capacity of the support nodes formed by the clamps or anchor bolts.

[0003] In the prior art, the pull rod on the pull-out bearing capacity detection device of the light steel roof clamp or anchor bolt is in an integral shape, which can fix the height limit position of the clamp, but the clamp or anchor bolt at some positions cannot be directly clamped, and the application range is poor. In order to solve the above problems, patent CN211453163U discloses a light steel roof clamp or anchor bolt pull-out bearing capacity detection device, including a placement frame, the upper end of the placement frame is fixedly connected to the gantry bracket, a puller is movably arranged in the gantry bracket, the piston rod of the puller passes through the gantry bracket and is fixedly connected to the pull rod, and the lower end of the pull rod is provided with A hollow rod is placed and extends into the hollow rod and the hollow rod is fixed at the upper end of the puller. A number of adjustment holes are equidistantly provided on the pull rod. A fastening bolt is provided at the upper edge of the right end of the hollow rod. The fastening bolt passes through the hollow rod and the adjustment holes on the pull rod and is threadedly connected with the first nut. This design can move the hollow rod up and down along the pull rod, thereby moving the puller and the clamping assembly up and down to a suitable height, and then use the fastening bolt and the first nut to fasten the pull rod and the hollow rod to adjust the upper and lower positions of the clamping assembly, facilitate the clamping work of the clamping assembly, and improve the scope of application.
