Anchoring strength testing device

Abstract

The invention discloses an anchoring strength testing device including a base, two parallelly arranged bearing seats are arranged on the base, the opposite sides of the two bearing seats are provided with a jack and a load sensor respectively, a protection net is arranged between the two bearing seats, the sides where the jack and the load sensor are arranged are slidably provided with protection devices, each of the protection devices includes a slide seat axially slipping along the jack, the slide seat is provided with a swing mechanism and a cover body connected with the swing mechanism, one end of the cover body is opened, the cover body forms a protection state or a discharging state through the swing of the swing mechanism, when in the protection state, the opening of the cover body abuts against the end face of the jack or the end face of the load sensor to form a protection bin, and when in the discharging state, the opening of the cover body faces upwards, and the inner side wall of the cover body is provided with an inclined surface for guiding the dropped anchoring component to slip to the bottom of the cover body when in the protection state. The anchoring strength testing device improves the safety in the testing process.

Description

technical field [0001] The invention relates to the technical field of engineering detection, and more specifically relates to an anchorage strength test device. Background technique [0002] The key to the use of prestressed tendons in concrete engineering is the anchoring component. The anchoring performance of the anchoring component is an important indicator of engineering safety performance. Therefore, the anchoring component needs to have strong bearing capacity and good adaptability. [0003] In the prior art, the Chinese patent document with the authorized announcement number CN203132856U discloses a static load anchoring experimental device, which consists of a frame, and jacks and load sensors are respectively installed at both ends of the frame; during the test, the steel strands are passed through the jack , frame, load sensor, and then connect the anchor component at both ends of the steel strand, push the anchor component through the jack to cause the steel cab...

AI Technical Summary

Problems solved by technology

[0004] In the existing engineering inspection, more and more attention is paid to the safety of the equipment. For example, the above-mentioned test equipment has safety measures such as setting a protective net on the frame, but there is no good safety guarantee when the anchor components are removed at both ends of the equipment. Because the anchoring component is tensioned by the pressure of the jack, when the anchoring effect between the steel strand and the anchoring component collapses, the anchoring component often falls directly; although this form has no effect on the anchoring test, it is not taken seriously , but it often damages the ground where the equipment is installed, resulting in pits, and there is a potential safety hazard of hitting people
