Buildings that have passed for a long time are at risk of collapse due to the elimination and conduction of some parts due to aging.
Accordingly, the need for safety accident prevention measures is being highlighted, and fundamental measures are needed.

The purpose is to prevent the risk of collapse due to building aging or earthquakes by conducting a safety inspection of the building and requesting an expert to repair and reinforce bricks in dangerous sections.

After punching the outer clay brick and inner wall, insert the CA20 anchor and use a dedicated tool to extend the anchor cartridge up to 6.75 mm
An anchor used in a construction method that expands and integrates the shared load of the two walls.

A high-strength plastic cartridge including stainless steel and brass cutouts, protrusions and expansion fixing parts, an insertion member that controls the movement of the cartridge, and a connection rod that aligns the cartridge through the cutout parts.

Ø10mm stainless steel and brass are the main components of the alloy 
The following structural performance has been verified.

1)Tensile load: 13 kN
2)Pulling load: Inner wall concrete 4.35 kN / Inner wall cement brick 3.33 kN
3)Shear load: Inner wall concrete 5.90 kN / Inner wall cement brick 5.44 kN
