Description

Anchor Assembly and Wall Reinforcement Apparatus having the same}

The present invention relates to an anchor assembly and a wall reinforcement device having the same.

In general, the outer wall of a building not only supports the load of the building, but also serves to protect the inside of the building against the outside air. The most representative example of such a protective role is insulation, ventilation, and awning.

The outer wall of the building is configured to include a load-bearing wall and a stucco brick wall formed by stacking bricks so as to be spaced apart from the heat-insulating material by applying an insulating material to the load-bearing wall.

A stucco brick wall is made by stacking individual bricks to form a wall. In some cases, parts are damaged by wear or load over a long period of time. Bleaching occurs and this part causes visual disgust. If left unattended for a long time, cracks easily occur in this part due to the contraction and expansion of the brick wall.

As such, in reinforced concrete structures, stucco bricks or stucco tiles fall off when an earthquake load is applied, which is a major cause of human life and property damage.

To reduce such damage, the proposed technology for seismic reinforcement of the decorative masonry of an existing building is very limited, and it is about inserting bolts (generally 13 mm in diameter or less) after coring at 400-600 mm intervals from the external masonry surface. This technology prevents partial fall-off and fall-off of the decorative masonry only by the bolt’s pull-out strength. When the bolt’s pull-out strength is weak and extensive brick peeling and detachment occurs, it is limited in preventing the targeted drop-off and fall-off. there is
