Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a building outer wall for repairing a tiled outer wall and the outer wall.

[0002]

2. Description of the Related Art For example, in a building in which 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 tiles or mortar may fall, which is dangerous, and rainwater or the like may enter the inside of the wall to cause various problems, and also the appearance may be impaired. Therefore, a structure of this type of wall is desired that does not fall off even if peeling is unavoidable. Moreover, since it is uneconomical to replace the entire wall with a little peeling, 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 as an outer wall of a foundation coated with a base mortar 2, and a tile 3 is adhered to the surface of the concrete wall 1 for joints. The plurality of tiles 3 were solidified by 4 to form a single plate. However, as time passes, floating 5 occurs on this wall, and if it is left as it is, the tile 3 may eventually fall off.

That is, when the base mortar 2 contains water, the water freezes or the base mortar 2 melts, so that the concrete wall 1 and the base mortar 2 are melted.
As shown in the figure, a float 5 is generated between and. When such a float 5 occurs, the tile 3 finally peels off together with the base mortar 2 and falls off. Since the peeling and dropping occur as a natural phenomenon, they 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.

When a float 5 is generated on the wall of the tile 3 in the prior art, as shown in FIGS. 6 and 7, the flange 6a at the head of the pin 6 formed in a T shape forms two tiles 3.
a, 3b, 3c, 3d, 3e, 3f, etc. are pressed, that is, the pin 6 is driven into the concrete wall 1 from the joint 4 and fixed with an adhesive, and the pin 6 formed in a T shape is pressed. The flange 6a is fitted into the one-character groove 7 formed in each tile 3, whereby two tiles 3
The pins e and 3f are pressed by one pin 6 so that each of the tiles 3 is fixed to the concrete wall 1.

Then, as shown in FIG. 8, an adhesive 8 is applied to the surface of the wall of the tile 3 which is fixed to the concrete wall 1 with pins 6, and a net 9 is attached to improve the bite of the mortar. Therefore, the finishing mortar 10 is applied onto the net 9 so that 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 prior art described above, when the float 5 is generated on the wall of the tile 3, the tile 3 is pressed and fixed by the flange 6a of the head of the pin 6, and further the pin 6 is fixed. Since the net 9 is attached to the surface of the tile 3 so as to cover the flange 6a, the net 9 itself has no holding force against the falling of the tile 3, and the peeled tile 3 is integrated by the net 9 instead. There was a problem that it became a large lump and fell out.

Further, when the lifted tile 3 is forcibly pressed by the pin 6, the extension due to the lift of the base mortar 2 pushes against the part around the pin 6 which is not pressed by the pin 6, and the part is pushed. The floating of the
When this floating limit is exceeded, that part will crack,
There is a problem that the useful life is shortened by peeling off, and in some cases, the urging of the extension due to the above-mentioned rise spreads to the normal tile 3 where it is not lifted and raises it.

Further, in order to stabilize the pressing of the tile 3 by the T-shaped flange 6a of the pin 6, it is necessary to form the one-character groove 7 on the tile 3 where the pin 6 is driven and fixed.
Since the number of pins 6 is large, there is a problem in construction that the work requires a great number of steps. Further, since the pins 6 need to be finely hammered so as to fix the tiles one by one, for example, when the pins 6 are hammered into a small tile 3 of about 2 cm square, the tile 3 may be cracked. In the case of a very small tile 3, there is a problem in construction that the pin 6 needs to be driven in with great care, and the construction method using the pin 6 cannot be adopted in some cases.

Further, since the portion of the wall surface of the tile 3 that is forcibly pressed by the pin 6 is hollow, and the other portion is raised, the surface of the tile 3 wall is swelled (landing). The net 9 is stretched along the swell even when the adhesive 9 is applied to the wall of the tile 3 having the swell and the net 9 is stretched, and the finishing mortar 10 is applied on the wall to finish the wall. If so, similar undulations appear on the surface of the finishing mortar 10.

Therefore, in order to eliminate this waviness, the layer of the finishing mortar 10 must be thickened,
A considerable skill is required to thicken the layer of the finishing mortar 10 to eliminate the undulation, which causes a problem in workability.
Further, if the layer of the finishing mortar 10 is thickened, there is also a problem that the mortar 10 easily drops.

The present invention solves the above-mentioned conventional problems by positively allowing the peeling of tiles rather than forcibly suppressing the peeling of tiles as in the conventional case. It is an object of the present invention to provide a method for constructing an outer wall for a building, which is improved and which can easily obtain a smooth finished surface without waviness and the outer wall.

That is, on the surface of the part where peeling has occurred due to the floating of the building outer wall where tiles are arranged on the surface of the foundation outer wall, latex mortar as a base material is thinly applied, a net is placed on the surface, and the latex of the base material is placed. Using a mortar, a net is attached to the surface of the mortar so that the net is in close contact with the mortar without wrinkles.

Then, a pin is driven into the outer wall of the foundation from above the net, and the net is pressed by a single flange spreading around the head of the net, and the net adhered in a tightly attached state is further strengthened. It is stretched to make the surface of the net smooth so that no waviness occurs, and the tiles that have been peeled off are pressed by the net to hold the outer wall in a state where peeling is allowed.

Also, when the pin for pressing the net is driven into the outer wall of the foundation from the surface of the tile, the head of the pin does not protrude from the surface of the stretched net, that is, the surface of the net and the head of the pin. Submerge the pin in the latex mortar so that it is approximately flush and pull the net with the flange of the pin.

Then, with the surface of the head of the pin not protruding from the net in this way, and latex mortar is applied to the surface of the net stretched so as to prevent waviness, and this latex mortar is applied to the net. Permeate through the eyes to permeate the back side of the net, and then stick and fix the net on the latex mortar, and apply the latex mortar to the surface of the net using this smooth net without waviness as a reference surface.

In this way, a thin layer of latex mortar is formed on the surface of the tile, and a net is arranged on the upper surface of the latex mortar. It is pressed by a pin having a flange, the pin is fixed to the outer wall of the foundation, and the head of the pin and the surface of the net are substantially flush with each other to form an outer wall for a building in which a layer of latex mortar is formed on the net. .

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 FIGS. 5 to 9 are designated by the same reference numerals in the following description. As for the wall at the time of new construction, a concrete wall 1 as a foundation outer wall is coated with a base mortar 2 and a tile 3 is adhered to the surface thereof and solidified with joints 4 to make the tile 3 into a single plate.

When a float 5 as shown in FIG. 5 is generated between the concrete wall 2 and the base mortar 2 of the outer wall 1, the construction method is the tile provided on the surface of the concrete wall 1. The aqueous solution 12 of ethylene vinyl acetate is applied to the surfaces of the three walls, and further the latex mortar 13 in which the latex made of water-soluble rubber is mixed in the mortar is applied, and the net 9 is provided on the surface thereof. The net 9 is fixed to the concrete wall 1 by pressing the net 9 on the head with a pin 14 having a single flange 14a extending around the head.

At this time, the net 9 is pulled in so that the pin 14 is submerged in the latex mortar 13, and the net 9 is pulled with a strong force to form a smooth surface of the net 9 with no undulation and the head of the pin 14 And the surface of the net 9 are flush with each other. By fixing the net 9 to the concrete wall 2 with the pins 14 in this manner, the tile 3 peeled from the concrete wall 2 is held by the net 9 while the peeling is allowed.

Pin 1 used to hold the net 9 down
4 is made of iron or plastic, and the head of the pin is hit with a hammer so that it is pushed into the hole 15 made in the concrete wall 2 from the joint 4. Then, by pushing the ball (not shown) mounted in the leg portion 14c through the hole 14b (see FIG. 3) of the head when pushed,
The portion of the cut 14d formed on the tip side of the leg portion 14c opens outward and serves as a stopper.

The intervals at which the pins 14 are driven are set to allow the peeling of the tiles 3 which are hardened by the base mortar 2 and formed into a single plate. In this way, the pins 14 can be driven into the space allowing the separation of the single plate-shaped tile 3 because the tile 3 is held by the net 9, and the tile 3 is held by the net 9. Therefore, even if the tile 3 is peeled off, it is held by the net 9 and does not fall off.

By pressing the net 9 with the single flange 14a extending around the head of the pin 14 as described above, a smooth surface of the net 9 having no undulation is formed as shown in FIG. , On top of which latex mortar 16
When you apply, the latex mortar 16 penetrates the eyes of the net 9 and wraps around to the back side of the net 9, and the net 9 is further attached and fixed with the latex mortar 13. By reference, the latex mortar 16 can be applied and a smooth layer of latex mortar 16 can be easily applied. Also, using the smooth surface of the net 9 as a reference surface, latex mortar 1
Since 6 is applied, the latex mortar 16 can be applied thinly (the latex mortar 16 layer in FIG. 1 is an enlarged view of the one in FIG. 2), and the construction period can be shortened.

Further, as shown in FIGS. 1 and 2, since the head of the pin 14 and the surface of the net 9 are substantially flush with each other, when the latex mortar 16 is applied again, the coating iron is moved. Alternatively, the spraying work can be carried out smoothly, and even if applied thinly, there is an effect that no uneven surface is generated on the surface. Thereby, the construction work can be easily performed. In FIG. 2, the reference numeral 17 is a finishing material.

By this construction method, the tile 3 is arranged on the surface of the concrete wall 1, a thin layer of the latex mortar 13 is formed on the surface of the tile 3, and the net 9 is arranged on the upper surface of the latex mortar 13. , The plurality of places of the arranged net 9 are pressed to the head by a pin 14 having a single flange 14a extending around the head, and the pin 14 is fixed to the concrete wall 2
The head of No. 4 and the surface of the net 9 are substantially flush with each other.
A building outer wall having a structure in which a thin layer of latex mortar 16 is formed on the above is constructed.

[0028]

According to the method of constructing an outer wall for a building according to the present invention, in the outer wall for a building in which tiles are arranged on the surface of the foundation outer wall, the base material is applied to the surface of the portion where peeling occurs due to the floating of the tile. As a thin coat of latex mortar,
Since the net is arranged on the surface of the tile, the net is adhered to the surface of the tile in close contact with no wrinkles by the latex mortar as the base material. As a result, the work of attaching the net can be easily performed.

After that, a pin is driven into the outer wall of the foundation from above this net, and the net is pressed by a single flange that spreads around the head of the net, and the net adhered in a tight state is further stretched. To make the surface of the net smooth with no undulations, and allow the separated tiles to be pressed by the net. Since the net holds the outer wall in a state in which the peeling due to the floating of the tiles is allowed, an excessive force is not applied to the lifted outer wall, and the durability of the outer wall can be maintained.

When the pin for pressing the net is driven into the outer wall of the foundation from the surface of the tile, the head of the pin does not come out from the surface of the stretched net, that is, the surface of the net and the head of the pin. It is possible to form a smooth net surface without undulations by sinking the head of the pin in the layer of latex mortar of the base material and pulling the net with the flange of the pin so that and become substantially flush. .

Then, by applying latex mortar to the surface of the net stretched so that no undulation occurs, with the head of the pin not protruding from the net, the net is exposed through the eyes of the net. Latex mortar also penetrates to the back side to further attach and fix the net to the latex mortar, so if you use this smooth net without waviness as a reference surface and apply latex mortar to the surface of the net, the latex mortar on the net The coating work is facilitated, the workability of the outer wall is improved, and the outer wall having an excellent appearance can be obtained.

Further, since the wall surface is held by allowing the separation by floating by the net, the strength of the latex mortar for supporting the wall surface is not required and the layer of the latex mortar can be thinned. Thereby, the construction period of the wall surface can be shortened to improve the construction workability, the load applied to the net can be reduced, and the durability of the wall surface can be improved.

As described above, a thin layer of latex mortar is formed on the surface of the tile, a net is arranged on the upper surface of the latex mortar, and a plurality of places of this arranged net are provided with wide flanges on the head. Workability, durability and undulation by holding the pin with the pin, fixing the pin to the outer wall of the foundation, making the head of the pin substantially flush with the surface of the net, and forming a thin latex mortar layer on the net. It is possible to obtain a clean exterior wall with a clean appearance.
