Description

Inspection system for chemical anchors using conductive materials The present invention relates to an inspection system for a chemical anchor using a conductive member, and more specifically, to an inspection system for a chemical anchor using a conductive member that allows the fixing status of the anchor bolt to be checked by injecting and positioning the conductive member together with the chemical anchor in a bore hole of a structure, thereby enabling the detection of poor fixing of the anchor bolt due to vibration and external environment, and thus preventing accidents in advance. Generally, for reinforcing structures made of concrete or stone, various types of chemical anchors are used in which a hole is drilled in the base material, such as stone, concrete, or rock, filled with a resin-based adhesive, and then an anchor bolt is inserted and fixed by allowing the adhesive to solidify. Polymer concrete compositions are used as the resin-based adhesives applied to these chemical anchors. Specifically, the composition used in chemical anchors consists of a main component in which calcium carbonate, sand, and silica fillers are mixed with unsaturated polyester resin, epoxy resin, polyurethane resin, phenolic resin, etc., and a curing agent such as benzoyl peroxide (BPO) that can rapidly cure the main component. A construction method using a chemical anchor according to the prior art is constructed by injecting a chemical anchor (4) containing a main component and a hardener into a fastening hole (2a) drilled in a concrete structure or a reinforced concrete foundation (2) as shown in FIG. 1, and then inserting an anchor bolt (5). Since the chemical anchor is in a liquid state at the time of injection, it has a hardening time of approximately 12 to 24 hours. However, the aforementioned conventional technology had a problem in that it lacked a means to inspect the fixing status of the anchor bolts after construction. Specifically, the anchor bolts were subjected to impact due to vibration and the external environment, causing their fixing strength to decrease compared to the initial state. Consequently, when the fixing strength of the anchor bolts decreased, the structure fixed to the anchor bolts detached, leading to accidents.
