Description

Technical Field

[0001] The utility model belongs to the technical field of anchoring force detection, and in particular relates to a building anchoring force detection device. Background Art

[0002] The anchoring force is the bonding force between the anchoring part of the anchor rod and the rock mass. It is the most important performance parameter of the anchor rod and also the maximum bearing capacity of the anchor rod. The greater the anchoring force, the more reliable the anchor rod and the better the anchoring effect. Its size is tested by a pull-out test. The maximum pull-out force measured for the same anchor rod is the anchoring force. After the pouring is completed at the construction site, the anchoring force of the building reinforcement needs to be tested to determine the bearing capacity of the building structure.

[0003] The public document (publication number CN216718041U) discloses a device for detecting the anchoring force of building rebars, comprising: a load meter for applying load and displaying measurement values; a cylinder, through which the load meter applies load to the rebars; an anchor for clamping the rebars to be tested; and a reaction force support ring.

The embedded steel bars and the wall are perpendicular to each other. However, in special building environments, the angle between the installed embedded steel bars and the wall is not a right angle, which causes a certain error in the detection of the anchoring force.
