Description

TECHNICAL FIELD

[0001] The utility model belongs to engineering quality detection technical field, concretely relates to a bearing plate for anchor rod locking force detection. BACKGROUND

[0002] As a reinforcing component widely used in many fields such as geotechnical engineering and underground structure support, the main function of anchor rod is to transmit tension to stable rock-soil body or structure, and to exert anchoring force on the reinforced object, so as to enhance the stability of rock-soil body or structure;

[0003] The appropriate anchor rod locking force can ensure that the anchor rod fully plays its reinforcing role, so that the rock-soil body or structure maintains a stable stress state, meeting the design requirements and safety standards of the corresponding project;

[0004] According to the search, the public (announcement) number: CN217897919U discloses a bearing plate for anchor rod locking force detection, which discloses "a bearing plate body, a mounting hole is formed at the top end of the bearing plate body, a mounting slot is formed at the top end of the mounting hole, and an annular iron plate is arranged inside the mounting slot. The utility model rotates the handle to drive the first screw rod to rotate, and the first screw rod moves the two threaded plates when rotating, so that the insert blocks on the two threaded plates move towards the annular iron plate, the insert blocks are inserted into the insert holes of the annular iron plate, and the annular iron plate is limited by the insert blocks. Then the bearing plate body can be used to bear the anchor rod, etc. Technical scheme has the technical effects of convenient detection of anchor rod by workers, convenient disassembly and assembly, etc. When disassembly is needed, workers only need to rotate the handle and the first screw rod in reverse direction to drive the insert blocks on the two threaded plates to move out of the insert holes, and then the annular iron plate can be taken out of the bearing plate body;

[0005] However, in the above-mentioned comparison file, the position of the anchor rod is not fixed, which may be on the ground, on the wall or on the rock wall. At this time, the bearing plate and the wall lack effective and adaptive fixing mode, which may cause the bearing plate and the wall to be unable to be closely and stably connected during use, so that the bearing plate is easy to shake and displace during detection. The shaking of the bearing plate will cause the force value obtained by the measuring equipment to fluctuate, which cannot truly reflect the locking force of the anchor rod, resulting in deviation of the detection result. This not only may cause the engineering personnel to make mistakes in judging the performance of the anchor rod, but also may threaten the safety of the building structure based on the wrong data for subsequent construction decision. Moreover, the unstable fixing mode will prolong the detection time and reduce the detection efficiency. During the detection process, the position of the bearing plate needs to be adjusted repeatedly to ensure its relative stability, which increases the labor and time cost, reduces the overall work efficiency and affects the engineering progress;

[0006] To solve the above problems, the anchor rod locking force detection bearing plate is provided in the application. Utility model content
