Description

[Detailed Description of the Invention] This invention relates to a device for preventing flaking of concrete exterior walls when applying an exterior wall finishing layer over mortar coating.

Conventionally, when tiles are pasted on top of a mortar coating on concrete exterior walls, accidents often occur in which the mortar and tiles come off. This was due to poor adhesion.

Various improved construction methods have been developed to prevent this peeling accident, but no definitive solution has yet been found.

This invention was devised in view of the above circumstances, and its details will be explained below based on illustrated embodiments.

The metal wire 1 is folded in half and the base end, that is, the bent part is buried in the base concrete 2, and the metal wires separated into two from one point protrude from the surface of the base concrete 2 by a required length.

When burying the base end of the metal wire in the concrete 2, for example, before concrete pouring, a hole is drilled in the formwork,
If a metal wire folded in half is set in this hole and concrete is poured, the metal wire will be buried integrally in the concrete.

Then, one end 1a of the metal wire 1, which has been folded back to have two protruding parts, is applied into the undercoat mortar 3 applied to the surface of the concrete 2.

Furthermore, the remaining end 1b of the metal wire 1 is coated with undercoating mortar 3.
Leave it protruding from the surface.

On the other hand, the end of the trigger 6 on the wire fixed in the hole 5 drilled on the back side of the tile 4 is tightly tied to one end 1b of the metal wire 1,
Attach the tiles to the surface of concrete 2.

FIG. 2 shows another embodiment of fixing the metal wire 1 to the concrete 2.

In this case, a metal wire is tied to the head of a concrete nail 7, and the concrete nail 7 is driven into concrete 2 to fix the metal wire 1.

This idea consists of the above-mentioned structure, and uses metal wires that are cast into the base concrete at the time of pouring or are fixed to the concrete by nailing after pouring, one metal wire is applied to the mortar coating layer, and the tiles are It is attached to the trigger and the other metal wire is tightly connected, and it can be physically integrated with the concrete by utilizing the strength of the metal wire, completely preventing the peeling of mortar and tile finishing material. can be prevented.
