Abstract

The invention relates to a force transmission device for an anti-pulling test and a detection method of the device. The force transmission device comprises a base arranged on the ground and located below an anchoring part, a guide mechanism arranged in the base, an inhaul cable wound on the guide mechanism, a limiting piece arranged at the top of the base and corresponding to the second end of theinhaul cable; and a reinforcing steel bar vertically connected to the limiting piece; the first end of the inhaul cable vertically and upwards protrudes out of the base and is vertically connected with the bottom end of the anchoring part, and the second end of the inhaul cable vertically and upwards protrudes out of the base; and the bottom end of the reinforcing steel bar is vertically connected with the second end of the inhaul cable, and the top end of the reinforcing steel bar forms a detection end. The pulling resistance of the anchoring part can be known by detecting the pulling resistance of the reinforcing steel bar through the detection end.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a force transmission device for a pullout test and a detection method thereof. Background technique [0002] In the post-concrete anchoring project, in order to ensure the construction quality of post-concrete anchors and the safe use of related buildings, it is necessary to carry out on-site sampling testing of the pull-out bearing capacity of post-concrete anchors. [0003] However, the testing equipment is erected on the ground, so it can only test the pull-out bearing capacity of the rear anchors close to the ground, and it is difficult to test the pull-out bearing capacity of the concrete rear anchors at high places, resulting in uneven sampling on site. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, provide a force transmission device and its detection method for the pull-out test, and solve the pro...
