Description

Technical Field

[0001] The utility model relates to the technical field of rear anchor performance testing, in particular to a rear anchor shear performance testing device. Background Art

[0002] Anchoring involves embedding rebar in concrete, creating a reliable connection with the concrete. The concrete effectively grips the rebar, creating a shared force between the two. Post-anchors are components that anchor the connected component to a base material like concrete. They differ from traditional pre-embedded anchoring methods primarily in that the rebar is anchored after the concrete has been poured. Compared to pre-embedded anchoring, post-anchors offer the advantages of ease of construction and flexibility.

[0003] Announcement No. (CN217688355U) discloses a shear test device for rear anchors. After the rear anchor shear test device and the rear anchor to be tested are installed, the left vertical plane of the second through hole is used as the zero point, and the reading S1 on the distance numerical scale of the clamping rod B is recorded; when the jack finishes working, the reading S2 on the distance numerical scale of the clamping rod B and the force F1 applied on the jack are recorded; the displacement S0 when the rear anchor is subjected to the maximum shear test load is S2-S1, and F1 is the maximum shear test load of the rear anchor. The above device cannot simulate real scenes for testing, and the test results may be affected, which needs to be improved. Utility Model Content
