Intelligent anchor bolt and steel plate support structure having same

Abstract

The invention discloses an intelligent anchor bolt. The anchor bolt comprises an anchor bolt seat, a screw, a nut and a gasket, wherein the gasket is sleeved on the screw and located between the anchor bolt seat and the nut; an axial pre-tightening force pre-warning mechanism is arranged on the intelligent anchor bolt; the pre-tightening force pre-warning mechanism comprises a signal acquisition unit, a control unit and a prompt unit; the signal acquisition unit comprises a stress sensor on the gasket; the stress sensor is used for acquiring deformation of the gasket and transmitting a signalto the control unit; and the control unit is used for judging and analyzing whether axial pre-tightening force of the anchor bolt is in a normal range or not according to information of the stress sensor, and sending a judging result to the prompt unit. The pre-tightening force of the anchor bolt can be monitored in real time and prompt information can be sent, so that the engineers can conveniently, rapidly and efficiently discover abnormal bolts and carry out inspect in time so as to eliminate hidden dangers and avoid dangers.

Description

technical field [0001] The invention relates to the field of construction engineering anchor components, in particular to an intelligent anchor bolt and a steel plate support structure with the intelligent anchor bolt. Background technique [0002] The anchor bolt is a component that tightly fixes the structure and the base. One end of the anchor bolt goes deep into the base to integrate, and the other end is tightly connected to the structure through a gasket and a nut. It is often used in the installation and fixing of equipment in places such as road bridges, dams, billboards, curtain walls, industrial plants, etc., to achieve the purpose of ensuring firm installation. [0003] In practical applications, due to irregular installation, changes in the environment, and natural aging, the pre-tightening force of the anchor bolts exceeds the bearing range or becomes loose, so that the effective bearing of the anchor bolts cannot be realized, and in severe cases, the anchors ma...

AI Technical Summary

Problems solved by technology

[0003] In practical applications, due to irregular installation, changes in the environment, and natural aging, the pre-tightening force of the anchor bolts exceeds the bearing range or becomes loose, so that the effective bearing of the anchor bolts cannot be realized, and in severe cases, the anchors may fall off. resulting in an accident

In order to avoid such accidents, it usually takes a lot of manpower to visually monitor the anchor bolts to check the anchor bolts in abnormal states such as looseness. This kind of check not only requires a lot of manpower and takes a long time, but also visual inspection is not reliable. Anchor bolts found to be a safety hazard

What is even more unfavorable is that the monitoring window time is limited in some occasions but the amount of anchor bolts to be monitored is huge, so manual monitoring is basically impossible
