Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for repairing existing external walls of buildings and structures, such as mortar walls, roof decks, wood board walls, steel board walls, and slate walls.

In conventional buildings, when an exterior wall, for example a cement mortar wall, is cracked or peeled over a wide area, it is necessary to remove the exterior wall and then form a new exterior wall. This work required an enormous number of days and man-hours, and had the disadvantage of damaging the pillars and the foundation.

Also, during the construction period, it will be necessary to construct tents and other temporary construction to prevent wind and rain from entering the building.
There were inconveniences such as having to cancel residence at some point. Furthermore, in order to save energy, conventional exterior walls lacked a heat-insulating structure, making them less comfortable to live in, and they also had the disadvantage of increasing heating and cooling costs. For this reason, when applying this type of heat insulation structure to a conventional outer wall, a method is known in which the space between the inner wall and the outer wall is filled with a heat insulating material. However, the disadvantage was that the entire wall had to be demolished, which required considerable cost and man-hours.

The present invention eliminates these drawbacks and inconveniences, and provides an exterior wall repair method that significantly improves livability, heat insulation, design, cost, and construction period.

Hereinafter, one embodiment of the exterior wall repair method according to the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing an example of the repair method according to the present invention, and Fig. 2 is an explanatory diagram showing the foundation part of the repair method according to the present invention. ) and is a prefabricated wall structure. To explain further, the existing wall structure has a wall 2 such as mortar, slate board, metal or ceramic siding board on the outer surface of stud l. Reference numeral 3 denotes a frame for attaching an architectural panel (hereinafter simply referred to as a panel) 6 that forms a repaired wall, which will be described later. It is installed with nails from the top to the bottom end. 4 is a sheet-like material,
It extends over the surface of the wall 2 or the surface of the rim 3, and is made of asphalt felt, terfelt, etc., and mainly functions as a waterproof material. To explain further,
The sheet-like material 4 is used as necessary depending on the condition of the wall 2. Reference numeral 5 denotes a heat insulating material, which is disposed between the rims 3 as necessary, and its material may be, for example, a board made of synthetic resin foam such as phenol foam or isocyanurate foam, gypsum board, or sheathing insulation. Board, wood chip cement board, particle board, calcium silicate board, glass wool, etc., or a composite thereof, which adds heat insulation, soundproofing, and fireproofing properties to the repaired wall. In addition, in the case of a hard board, the shape is a rectangular solid shape (Fig. 5A) with the same thickness as the thickness of the rim 3, as shown in Figs. 5(a) to (el). or cover it with a waterproof surface material 5b (
(b) figure), the surface material 5b covering one side of the board 5a is made to protrude from one side of the boat 5a or two adjacent sides (
