Description

[Detailed Description of the Invention] This invention relates to a device for preventing flaking of external wall mortar finishing material in concrete external walls.

Traditionally, when applying mortar to concrete exterior walls, many accidents have occurred where the mortar has come off, but this is caused by poor adhesion at the interface between the underlying concrete and the mortar, or at the interface between the mortar coating layer. It was something.

Various improved construction methods have been developed to prevent these flaking accidents, but no definitive solution has yet been found.

There are also cases where surface finishing materials are installed using insert metal fittings, but this cannot be applied to walls with multiple layers of paint.

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

FIGS. 1 to 3 show a device for preventing peeling of external wall mortar.

That is, a metal wire 1 such as a stainless steel wire is folded in two and the base end, that is, the bent part is buried in the base concrete 2,
The two metal wires are separated from one point and 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, as shown in FIG. If you set the metal wire 1 and pour the concrete 2,
is buried integrally in concrete 2.

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 5 applied to the surface of the concrete 2.

Furthermore, the remaining end 1b of the metal wire 1 is coated with undercoating mortar 5.
The finishing mortar 6 is coated on the surface of the mortar.

In addition, if the mortar has a three-layer finish, the metal wire 1
An additional one is buried (not shown).

Note that this metal wire is installed at multiple locations on the surface of the concrete 2.

FIG. 4 shows another embodiment of fixing the metal wire 1 to the concrete 2.

In this case, the metal wire 1 is tightly tied to the head of a concrete nail 11, and the concrete nail 11 is driven into concrete 2 to fix the metal wire 1.

This invention consists of the above-mentioned structure, and the base end is fixed by nailing into the concrete at the time of pouring into the base concrete or after pouring, and the metal wire is separated into multiple pieces from one place and is inserted from the base concrete surface. When finishing the mortar, a metal wire is applied to each coating layer of mortar to prevent peeling and peeling between each layer, and physically integrate the concrete and coating layers such as mortar using the strength of the metal wire. It is possible to completely prevent finishing materials such as mortar from peeling off.
