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 excellent in durability and an outer wall thereof.

[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 tiles 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,
It is desirable for this type of wall to have a structure that does not fall off even if peeling is inevitable. Further, 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 of which is shown in FIG. 5, the outer wall 1 at the time of new construction is a concrete wall 2 serving as a foundation outer wall, a base mortar 3 is applied to the surface thereof, and a mortar 4 is applied to the surface of the concrete wall 2 to solidify the outer wall. 1 was in the form of a plate. However, with the passage of time, the outer wall 1 has floats 5, and if left as it is, finally the mortar 4
Comes off.

That is, when the base mortar 3 contains water, the water freezes or the base mortar 3 melts, so that the concrete wall 2 and the base mortar 3 are melted.
As shown in the figure, a float 5 is generated between and. When such a float 5 is generated, the mortar 4 finally peels off together with the base mortar 3 and falls off. Since the peeling and dropping occur as a natural phenomenon, they are generally inevitable. Therefore, in order to prevent the mortar 4 from falling off, it is necessary to repair the wall of the mortar 4 at the time when the float 5 occurs.

When a float 5 is generated on the mortar 4 in the related art, the mortar 4 is pressed by the flange 6a of the head of the pin 6 formed in a T shape as shown in FIG. Flange 6 of pin 6 formed in a letter shape
While a is fitted in the one-character groove 7 formed in the mortar 3,
Drive the pin 6 into the concrete wall 1 and fix it with an adhesive,
The mortar 4 is fixed to the concrete wall 2.

Then, as shown in FIG. 7, the surface of the mortar 4 wall fixed to the concrete wall 1 with the pins 6 is coated with an adhesive 8 and a net 9 is attached to improve the bite of the mortar 4 and the net 9 The finishing mortar 10 is applied to the top of the above, and the finishing mortar 10 presses the net 9 integrally. Finally, as shown in FIG. 8, the surface of the finishing mortar 10 is formed into a smooth surface 11 for final finishing.

[0007]

In the prior art described above, when a float 5 is formed on the wall of the mortar 4, the mortar 4 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 mortar 4 so as to cover the flange 6a, the net 9 itself has no holding force against the mortar 4 coming off,
On the contrary, there is a problem that the separated mortar 4 is integrated by the net 9 and becomes a large lump and falls off.

Further, when the lifted mortar 4 is forcibly pressed by the pin 6, the extension due to the lift of the mortar 4 is pressed to the portion around the pin 6 which is not pressed by the pin 6, and There is a problem that the floating of the part becomes even larger, and when the floating limit is exceeded, the part cracks or peels off and the service life is shortened.In some cases, the amount of extension due to the above lifting does not rise There is also a problem that it spreads to normal mortar 4 and raises it.

In order to forcibly press the floating mortar 4 with the pin 6, it is necessary to drive a large number of pins 6, and the T-shaped flange 6a is used to stabilize the pressing of the mortar 4. There was a problem in construction that the mortar 4 at the portion where the 6 was driven in had to be machined with a groove 7 of one character, and the number of pins 6 was large, which required a great number of man-hours for the work.

Further, since the portion of the wall surface of the mortar 4 which is forcibly pressed by the pin 6 is hollow and the other portion is raised, the wall surface of the mortar 4 has a swell (landing). It has occurred and this undulating mortar 4
Even if the net is stretched along the swell, the mortar can be applied to the surface of the A similar swell appears on the surface of.

Therefore, in order to eliminate this undulation, it is necessary to thicken the mortar layer, and in order to eliminate the undulation by thickening the mortar layer, considerable skill is required. There is a problem in terms of sex. Further, if the mortar layer is thickened, there is a problem that the mortar easily falls.

The present invention solves the above-mentioned conventional problems by positively allowing the peeling of mortar instead of forcibly suppressing the peeling of the mortar 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.

[0015]

The construction method of the outer wall for a building according to the present invention is configured as described above, and thus has the following effects. That is, on the surface of the part where peeling occurred due to the floating of the outer wall of the building where the mortar was arranged on the surface of the foundation outer wall, latex mortar as a base material was thinly applied, and a net was placed on that surface, and the latex of the base material was 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. The surface of the net is stretched to be a smooth surface in which no waviness occurs, and the separated mortar is pressed by the net to hold the outer wall in a state where the separation is allowed.

When the pin for pressing the net is driven into the outer wall of the foundation from the surface of the mortar, 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 mortar, 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 8 will be described with the same reference numerals. The outer wall 1 at the time of new construction applies concrete mortar 3 to the concrete wall 2 as the foundation outer wall,
Mortar 4 is applied to the surface and hardened to form the outer wall 1 into a single plate.

When a float 5 as shown in FIG. 5 is generated between the concrete wall 2 and the base mortar 3 of the outer wall 1, the method of construction is to set the mortar on the surface of the concrete wall 2. 4 is coated with an aqueous solution 12 of ethylene vinyl acetate, and then a latex mortar 13 in which a latex made of a water-soluble rubber is mixed in mortar is coated thereon, and a net 9 is arranged on the surface thereof. The net 9 is fixed to the concrete wall 2 by pressing 9 on the head and 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 way, the mortar 4 separated from the concrete wall 2 is held by the net 9 while the separation is allowed.

Pin 1 used to hold the net 9 down
Reference numeral 4 is made of iron or plastic, and the head of the pin is hit with a hammer to push it into the hole 15 formed in the concrete wall 2. Then, when pushed, a ball (not shown) mounted in the leg portion 14c is pushed through the hole 14b (see FIG. 4) in the head portion, so that the leg portion 14c
The portion of the cut 14d formed on the tip side of the is opened to the outside to prevent it from coming off.

The intervals at which the pins 14 are driven are set to allow the peeling of the mortar 4 which is hardened by the base mortar 3 and has a single plate shape. In this way, the pins 14 can be driven at intervals allowing the separation of the single plate-shaped mortar 4 because the mortar 4 is held by the net 9, and the mortar 4 is held by the net 9. Therefore, even if the mortar 4 peels 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 mortar 4 is provided on the surface of the concrete wall 2, a thin layer of the latex mortar 13 is formed on the surface of the mortar 4, and the net 9 is provided on the upper surface of the latex mortar 13. , A plurality of places of the arranged net 9 are held by the head 14 by a pin 14 having a single flange 14a extending around the head,
Also, for the construction of a structure in which the pin 14 is fixed to the concrete wall 2, the head of the pin 14 and the surface of the net 9 are substantially flush with each other, and a thin layer of latex mortar 16 is formed on the net 9. The outer wall is built.

[0028]

According to the method for constructing an outer wall for a building according to the present invention, in the outer wall for a building in which mortar is arranged on the surface of the foundation outer wall, the base material is applied to the surface of the portion where the mortar is separated due to the floating. Since the latex mortar as is used as a thin coat and the net is arranged on the surface thereof, the net is adhered to the surface of the mortar by the base material latex mortar without wrinkling or the like. 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 the net, and the net is pressed tightly with one francie spread around the head of the net, and the net attached in a tight state is further stretched. To make the surface of the net smooth with no undulations and allow the separated mortar to be pressed by the net. The net holds the outer wall in a state that allows the mortar to separate due to floating, so
Unreasonable force is not applied to the raised 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 mortar, the head of the pin should 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 mortar, and a net is placed on the upper surface of the latex mortar. 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.
