Abstract

PURPOSE:To prevent peeling of tiles by arranging a concrete wall, a bed mortar layer, and a tile layer, and planting the anchor material, which is coated with aluminium and epoxy resin, in the concrete wall. CONSTITUTION:Anchor members 4 made of a U-shape steel material are planted in the concrete wall 1, and the surface of this anchor member 4 is coated with aluminium and epoxy resin in order from the surface. One side part of the concrete wall 1, where the anchor member 4 is projected, is coated with mortar to form the bed mortar layer 2, and tiles 3 are attached onto the mortar layer 2. Consequently, the adhesive force of the wall 1 and the bed mortar layer 2 is strengthened to prevent peeling of the tiles 3.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the structure of a tiled exterior wall that prevents tiles from falling off.

0002

[Means for solving the problem] Falling off of exterior wall tiles can be life-threatening, and there is a strong need for countermeasures. When looking at the cross section of the exterior wall where the tiles have fallen off, it is found that the tiles have peeled off between the concrete wall and the base mortar layer, and the base mortar layer often has an uneven thickness of 30 mm to 50 mm. It is thought that this peeling is caused by repeated drying of the mortar layer, cracking due to shrinkage, and repeated infiltration of rainwater through cracked areas.

[0003] This invention was made in view of the above circumstances. The purpose of this is to create strong adhesion between the concrete frame surface and the underlying mortar layer, making it difficult to peel off due to rainwater infiltration.
To propose a tiled exterior wall structure that can prevent tiles from falling off.

0004

[Means for solving the problem] The structure of this tiled exterior wall consists of a concrete frame wall, a base mortar layer, and a tile layer arranged in this order, and the concrete frame wall has anchor materials that protrude into the base mortar layer. This anchor material is made of steel, and its surface is coated with aluminum and epoxy resin in order from the bottom.

[0005]

[Example] Fig. 1 shows a tiled external wall having the structure of the present invention, which is composed of a concrete frame wall 1, a base mortar layer 2, and a tile layer 3. One side thereof protrudes into the base mortar layer 2. The anchor material 4 is made of steel, and its surface is coated with layers of aluminum and epoxy resin in order from the bottom.To construct the tiled exterior wall of this structure, the construction flow diagram shown in FIG. 2 is followed.

[0006] That is, a formwork for pouring a concrete frame is assembled, and holes are drilled at positions in the formwork where anchor materials are to be planted. Concrete is poured into the formwork and L-shaped anchors are inserted through the holes. After allowing the concrete to harden, dismantle the formwork and scrub the wall surface of the structure with a wire brush, etc. to remove the release agent that has migrated from the formwork surface. If necessary, perform sanding, etc. to ensure that the wall surface of the frame has a high level of flatness and that no release agent remains.

[0007] After bending the anchor material into a U-shape and applying an adhesive (for example, Hylex #1000) to the wall surface, a base mortar coating (comb pattern) (1:2.5 mortar) is performed.

[0008] A base mortar coating (1:3 mortar) is further applied on top of this, and tiles are pasted on top of that.

[0009]

[Function] The structure of this tiled exterior wall consists of the above-mentioned structure. An anchor material that protrudes into the base mortar layer is planted in the concrete frame wall, and a strong bond between the frame wall and the base mortar layer is established through this anchor material. Adhesion is attempted. The surface of this anchor material is coated with a layer of aluminum and epoxy resin, and it has excellent corrosion resistance, so even if rainwater penetrates into the underlying mortar layer, it will not rust and promote cracking of the mortar layer, and its strength will increase. It maintains strong adhesion between the concrete wall and the underlying mortar layer over a long period of time without causing any risk of deterioration, and prevents tiles from falling off.

0010

[Effects of the Invention] This structure of the tiled exterior wall maintains the adhesion between the concrete frame wall and the base mortar layer over a long period of time, and has the effect of preventing tiles from falling off.
