Description

Support device for rebar explorer for safety diagnosis {SUPPORTING APPARATUS FOR REBAR EXPLORATION DEVICE FOR SAFETY DIAGNOSIS}

The present invention relates to a support device for a rebar explorer for safety diagnosis of a reinforced concrete structure.

In general, in order to estimate the location, direction, and thickness of the cover of the reinforcing bars placed inside the reinforced concrete structure, the electromagnetic wave transmitted to the inside of the reinforced concrete structure causes a reflected wave at the boundary of the reinforcing bar, which is a material with different electrical characteristics. The measuring instrument used is a rebar explorer.

This rebar explorer is a non-destructive inspection device based on the principle of magnetic induction, and detects the reinforcement state of the reinforcement by conducting it on slabs and walls of reinforced concrete structures.

On the other hand, steel probes of reinforced concrete structures are applied in various ways such as radar survey, magnetic survey, radiation survey, and ultrasonic survey. proceeds in a way

In this way, the reinforced concrete probe, in which signals are sent and received at the center of the bottom, travels along the surface of the reinforced concrete structure for non-destructive exploration of the reinforced concrete structure.

(eg, rebar exploration) is performed. When the surface of the reinforced concrete structure is smooth, non-destructive exploration (eg, rebar exploration) of the reinforced concrete structure is performed while the rebar explorer stably runs.

However, even if the reinforced concrete structure is flat, if the surface has many curves, the center of the lower surface of the reinforcing bar explorer is in contact with the surface of the reinforced concrete structure, causing malfunction of the distance measurement sensor and reinforcing bars because the wheels of the reinforcing bar finder do not rotate properly. There is a problem in that stable driving of the rebar explorer and transmission/reception of signals are impossible due to damage caused by abrasion of the lower surface of the explorer.

To solve this problem, a support device for a rebar explorer is used. For example, a support device for rebar explorer is a device disposed between a reinforced concrete structure and a rebar explorer to guide the stable driving of the rebar explorer.

However, the conventional support device for a reinforcing bar explorer can search for reinforcing bars only in a reinforced concrete structure of which size has already been determined, and when the size of the reinforced concrete structure is large or small, several supporting devices are installed in the reinforced concrete structure or small There was a problem in that the installation work and cost of the supporting device accordingly increased because a support device of the size should be provided separately and installed on the reinforced concrete structure.
