Abstract

PURPOSE:To enhance the workability and the durability of an outer wall by positively allowing peel-off of mortar without preventing peel-off thereof. CONSTITUTION:In an outer wall in which mortar 4 is laid on the outer surface of a wall base, a net 9 laid on the outer surfaces of the mortar 4 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 mortar 4 is allowed, but the net 9 prevents the mortar from dropping. With the outer wall obtained by this construction method, having the mortar 4 which is laid on the outer surface of the wall base, the net 9 laid on the outer surface of the mortar 4 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 mortar is held by the net 9, thereby it is possible to obtain a building outer wall which allow peel-off of the mortar 4 and which may be easily constructed while its durability is excellent.

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 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 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.

An example of a conventional wall structure is shown in FIG. 5, and an outer wall 1 at the time of new construction is constructed by applying a base mortar 3 on a concrete wall 2 serving as a foundation outer wall, and applying mortar 4 on the surface thereof to solidify the outer wall 1. Was in the form of one plate. However, with the passage of time, the outer wall 1 has floats 5, and if left as it is, the mortar 4 will eventually fall off.

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

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

Then, as shown in FIG. 7, an adhesive 8 is applied to the surface of the mortar 4 wall fixed to the concrete wall 1 with the pin 6.
Is applied to improve the bite of the mortar, and the finishing mortar 10 is applied on the net 9 so that the finishing mortar 10 presses the net 9 together. 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 the float 5 is generated on the wall of the mortar 4, the mortar 4 is pressed and fixed by the head 6a of the pin 6, and the head 6a of the pin 6 is fixed. Since the net 9 is attached to the surface of the mortar 4 so as to cover it, the net 9 itself has no holding force for the mortar 4 to fall off, and the peeled mortar 4 is instead integrated by the net 9 and falls off as a large lump. There was a problem.

Further, in order to stabilize the pressing of the mortar 4 by the T-shaped head 6a, it is necessary to form a groove 7 of one letter in the portion of the mortar 4 where the pin 6 is driven in and stopped, and the number of pins 6 is large. There was a construction problem that the work required a great number of man-hours.

The present invention solves the above-mentioned conventional problems by positively allowing the peeling of mortar instead of preventing the peeling of mortar as in the conventional case, and is for a building having improved workability and durability. An outer wall construction method and an outer wall are provided.

[0010]

As a means for solving the above problems, the present invention provides an outer wall in which mortar is provided on the surface of a foundation outer wall, in which a net is provided on the head after the net is provided on the surface of the mortar. It is a construction method characterized by allowing the mortar to peel off by pressing it with a pin having a wide area flange, and retaining the mortar falling off by a net, and the outer wall obtained by this construction method is the surface of the foundation outer wall. On the outer wall where the mortar is placed,
It is characterized in that a net is provided on the surface of the mortar, a plurality of portions of the net are pressed by a pin having a flange having a large area on the head, and the pins are fixed to the outer wall of the foundation.

[0011]

Since the present invention is constructed in this way, in the outer wall where the mortar is arranged on the surface of the foundation outer wall, after the net is provided on the surface of the mortar, the net is formed by the pin having the large area flange on the head. By pressing, the net is fixed by the pin and the mortar is held by the net. By holding the mortar with the net in this way, exfoliation of the mortar is allowed.

[0012]

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. 8 will be described with the same reference numerals. As the outer wall 1 at the time of new construction, a concrete wall 2 serving as a foundation outer wall was coated with a base mortar 3 and the surface thereof was coated with mortar 4 to solidify the outer wall 1 into a single plate.

When a float 5 as shown in FIG. 5 is generated between the outer wall 1 and the concrete wall 2 and the base mortar 3, for example, the method of construction is to use the mortar 4 provided on the surface of the concrete wall 2. An aqueous solution 12 of ethylene vinyl acetate is applied to the surface, a latex mortar material 13 in which a latex made of a water-soluble rubber is mixed with a mortar material is applied to the surface of the solution, and a net 9 is provided on the surface of the mortar material. The net 9 is fixed to the concrete wall 2 by pressing the head 14a with a pin 14 having a large area flange. As a result, the net 9 is fixed to the concrete wall 2 via the pin 14, and the mortar 4 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 into the hole 15 made in the concrete wall 2. And when pushed in, the head 14a
By pushing a ball (not shown) mounted in the leg 14c through the hole 14b of the leg 14c (see FIG. 4), the portion of the cut 14d formed at the tip side of the leg 14c is opened to the outside to prevent slipping out. It will be.

The intervals at which the pins 14 are driven are set to allow the peeling of the mortar 4 in the form of a single plate which is solidified with the base mortar 3. In this way, the pins 14 can be driven into the space allowing the separation of the mortar 4 in the form of a single plate because the mortar 4 is held by the net 9, and the mortar 4 is held by the net 9. Even if the mortar 4 peels off, it 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 large 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 again with the latex mortar material 16, the coating iron can be moved or sprayed smoothly, and the construction work can be facilitated. Become. Therefore, the latex mortar material 16 to be applied again can be thinly applied, and even if it is thinly applied, an uneven surface is not generated. In FIG. 2, reference numeral 17 is a finishing material.

By this construction method, the mortar 4 is arranged on the surface of the concrete wall 2, and a plurality of portions of the net 9 provided on the surface of the mortar 4 are held by the head 14a with the pin 14 having a wide flange, and The building outer wall having a structure in which the pin 14 is fixed to the concrete wall 2 is constructed.

[0018]

As described above in detail, according to the present invention, in the outer wall in which the mortar is arranged on the surface of the foundation outer wall, the net provided on the surface of the mortar is pressed by the pin having the wide area flange on the head. The net is fixed by pins and the mortar is held by the net. Since the mortar is held by the net to allow the mortar to be peeled off in this manner, even if the mortar is lifted up and the mortar is peeled off, the mortar is held on the net and does not fall off. This improves the durability of the outer wall. Also, since pins were driven in at an interval where peeling of the mortar was allowed and the net was stopped by the pins and the mortar was held by the net, it is also necessary to form a groove for stopping the pins in the mortar.
There is no need to drive many pins, and repair work becomes easy and easy.
