Problems solved by technology
The experiment failed, and the anchorage could no longer be used due to the addition of adhesive, and the tendon body was damaged to a certain extent because of the tension of the tendon body.
Such ribs cannot be used in the study of material properties
Therefore, the failure test of pulling out the ribs caused by the traditional anchorage will cause a relatively large waste of materials.

The present invention discloses an assembled elastic anchorage device which comprises an anchorage device upper portion, an anchorage device lower portion and a rib body, a first through hole and a second through hole are formed in the anchorage device upper portion in the axial direction, and the diameter of the first through hole is smaller than that of the second through hole; a third through hole is formed in the lower portion of the anchorage device in the axial direction, the end of the lower portion of the anchorage device is inserted into the second through hole, internal threads are arranged in the second through hole, and external threads matched with the internal threads are arranged on the lower portion of the anchorage device; and the rib body penetrates through the second through hole to be inserted into the first through hole, a spring and an elastic metal piece are arranged between the second through hole and the rib body, and the anchorage device can effectively solve the problem that the rib body is pulled out of the anchorage device in a tensile test.
Description
technical field [0001] The invention belongs to the technical field of anchors, and relates to an assembled elastic anchor. Background technique [0002] In the study of material properties, tensile tests and axial compression test pieces are inseparable from the use of anchorage. Take the tensile test as an example. In the tensile test, there are many reasons for the failure of the test, but the most common one is that the tendon is pulled out from the anchor. The reason is that the traditional way of anchoring the tendons is mostly by adding colloid, which acts as a medium for force transmission between the anchorage and the tendons. However, when the joint force between the colloids is less than the external force loaded by the testing machine, and the tendons have not yet completed the tensile test of the tendons at this time. At this time, the bonding stress between the colloids disappears, and the tendons are pulled out from the anchorage. The experiment failed, and...
