Abstract

PURPOSE:To enhance the workability and the durability of an outer wall by positively allowing peel-off of tiles without preventing peel-off thereof. CONSTITUTION:In an outer wall in which tiles 3 are laid on the outer surface of a wall base, a net 9 laid on the outer surfaces of the tiles 3 is retained by means of pins 14 each having a head part 14 formed therearound with a wide flange so that the peel-off of the tiles is allowed, but the net 9 prevents the tiles from dropping. With the outer wall obtained by this construction method, having tiles 3 which are laid on the outer surface of the wall base, the net 9 laid on the outer surface of the tiles 3 is retained at several positions by the pins 14 each having a head part 14a formed therearound with a width flange, and the, pins 14 are secured to the wall base. Since the net 9 is fixed by the pins while the tiles are held by the net 9, thereby it is possible to allow peel-off of the tiles.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing an outer wall for a building which is easy to construct and has excellent durability, and an outer wall.

[0002]

2. Description of the Related Art For example, in a building where the outer wall is tiled or mortar finished, the outer wall may rise from the inside and the tile or mortar may peel off as the years of use pass. When the outer wall is peeled off in this way, the peeled mortar or tile may fall, which is dangerous, and rainwater or the like may enter the inside of the wall to cause various problems, and the appearance is also impaired. Therefore, it is desirable for this type of wall to have a structure that does not fall off even if peeling is inevitable. Further, it is uneconomical to replace the entire wall with a little peeling, so the peeled portion is partially repaired.

As an example of a conventional wall structure, an example is shown in FIG. 5, and the wall at the time of new construction is a concrete wall 1 serving as an outer wall of a foundation coated with a base mortar 2 and a tile 3 on the surface thereof.
Was bonded and solidified with joints 4 to form a plurality of tiles 3 into a single plate. However, as time passes, a floating 5 is generated on this wall, and if it is left as it is, the tile 3 will eventually fall off.

That is, when water is contained in the base mortar 2, the water freezes or the mortar melts, so that between the concrete wall 1 and the base mortar 2,
As shown in the figure, the float 5 is generated. When such a float 5 occurs, the tile 3 finally peels off together with the base mortar 2 and falls off. This peeling and dropping occur as a natural phenomenon and are generally inevitable. Therefore, in order to prevent the tile 3 from falling off, it is necessary to repair the wall of the tile 3 at the time when the float 5 occurs.

In the prior art, when a float 5 is generated on a tile 3, two tiles 3a, 3b, 3c, 3d are formed by a head 6a of a pin 6 formed in a T shape as shown in FIGS. ， 3e,
3f ... so that the pin 6 is pressed into the concrete wall 1 from the joint 4 and fixed with an adhesive, and the head 6a of the T-shaped pin 6 is formed in each tile 3 7 so that, for example, 2
The tiles 3e and 3f are held by one pin 6, and each of the tiles 3 is fixed to the concrete wall 1.

Then, as shown in FIG. 8, the surface of the tile 3 wall fixed to the concrete wall 1 with the pin 6 is coated with an adhesive 8 to attach a net 9 to improve the bite of the mortar, and then the net. The finishing mortar 10 is applied on 9 and the finishing mortar 10 presses the net 9 together. Finally, as shown in FIG. 9, the surface of the finishing mortar 10 is formed into a smooth surface 11 for the final finishing.

[0007]

In the conventional technique described above, when the float 5 is generated on the wall of the tile 3, the tile 3 is pressed and fixed by the head 3a of the pin 6, and the head 3a of the pin 6 is fixed. Since the net 9 is attached to the surface of the tile 3 so as to cover it, the net 9 itself does not have a supporting force against the falling of the tile 3, and the peeled tile 3 is integrated by the net 9 into a large mass. There was a problem of falling out.

In order to stabilize the pressing of the tile 3 with the T-shaped head 6a, it is necessary to form a single groove 7 on the tile 3 at the portion where the pin 6 is driven in and stopped. There was a construction problem that required a great number of man-hours. Further, the pin 5 needs to be finely driven so that each tile 3 is fixed, so that, for example, 2c
When the pin 5 is driven into a tile having a small size of about m square, the tile may be cracked. In such a small tile, it is necessary to pay close attention to the driving of the pin. There was a problem in construction that it could not be adopted.

The present invention solves the above-mentioned conventional problems by positively permitting the peeling of tiles, rather than preventing the tiles from peeling as in the conventional case, and improves the workability and durability of the building outer wall. It provides a construction method and an outer wall.

[0012]

As a means for solving the above problems, the present invention provides an outer wall in which tiles are arranged on the surface of a foundation outer wall, and after the net is provided on the surface of the tile, the net is placed on the head. It is a construction method characterized by allowing the tile to peel off by holding it with a pin having a wide area flange, and retaining the fall of the tile with a net. The outer wall obtained by this construction method is the surface of the foundation outer wall. In the outer wall on which the tile is arranged, a net is provided on the surface of the tile, and a plurality of points of the net are pressed by a pin having a wide area flange on the head and the pin is fixed to the foundation outer wall. To do.

[0013]

Since the present invention is constructed as described above, in the outer wall in which the tile is arranged on the surface of the foundation outer wall, after the net is provided on the surface of the tile, the net is pressed by the pin having the wide area flange on the head. By doing so, the net is fixed by the pins and the tiles are held by the net. By holding the tiles with the net in this manner, peeling of the tiles is allowed.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The same members as those in FIG. 9 will be described with the same reference numerals. As for the wall at the time of new construction, a concrete wall 1 as an outer wall of a foundation is coated with a base mortar 2, a tile 3 is adhered to the surface thereof, and the tiles 3 are solidified with joints 4 to form a single plate.

A float 5 as shown in FIG. 5 is provided between the concrete wall 1 and the base mortar 2 on the outer wall.
If any of the above occurs, the construction method is to apply the aqueous solution 12 of ethylene vinyl acetate to the surface of the tile 3 provided on the surface of the concrete wall 1 and further mix the latex made of water-soluble rubber into the mortar material. The latex mortar material 13 is applied, the net 9 is arranged on the surface thereof, and the net 9 is fixed to the concrete wall 1 by pressing the net 9 with the pin 14 having the wide flange on the head 14a. As a result, the net 9 is fixed to the concrete wall 1 via the pin 14, and the tile 3 is held by the net 9.

The pin 14 used to hold down the net 9
Is made of iron or plastic and the head 14a of pin 14
I hit it with a hammer and push it from the joint 4 into the hole 15 made in the concrete wall 1. Then, when pushed in, a ball (not shown) mounted in the leg 14c is pushed through the hole 14b (see FIG. 3) of the head 14a, so that the cut 14d formed at the tip side of the leg 14c The part opens outward to prevent it from slipping out.

The intervals at which the pins 14 are hit are such that the peeling between the base mortar 2 and the tile 3 in the form of a single plate, which is solidified by the joints 4, is allowed. In this way, the pins 14 can be struck at an interval that allows separation of the single plate-shaped tile 3 because the tile 3 is held by the net 9. The tile 3 is held by the net 9 so that the tile 3
Even if peeled off, the tile 3 is held by the net 9 and does not fall off.

By pressing the net 9 on the head 14a with the pin 14 having a wide area flange, the upper end of the flange can be flush with the net 9 as shown in FIG. As a result, as shown in FIGS. 1 and 2, even when the upper surface of the pin 14 is coated with the latex mortar material 16 again (see FIGS. 1 and 2), the movement or spraying work of the coating iron is smoothly performed. This makes the construction work easier. Therefore, the latex mortar material 16 to be applied again can be thinly applied, and even if thinly applied, there is an effect that no uneven surface is generated on the surface. Figure 2
Among them, the reference numeral 17 is a finishing material.

With this construction method, in the outer wall in which the tiles 3 are arranged on the surface of the concrete wall 1, a plurality of places of the net 9 provided on the surface of the tiles 3 are held by the heads 14a with the pins 14 having wide flanges. In addition, the building outer wall having a structure in which the pin 14 is fixed to the concrete wall 1 is constructed.

[0020]

As described above, according to the present invention, in the outer wall in which the tile is arranged on the surface of the foundation outer wall, the net covered on the surface of the tile is pressed by the pin having the wide area flange so that the net is formed by the pin. The tiles are fixed and held by the net. In this way, since the tiles are held by the net to allow the peeling of the tiles, the tiles are lifted, and even if the tiles are peeled off, the tiles are held by the net and do not fall off. This improves the durability of the outer wall. Moreover, since the nets are held by the pins by driving the pins at an interval that allows the peeling of the tiles and the nets are held by the pins, one tile
Repair work is easy because there is no need to form grooves in the sheet and to drive a large number of pins.
