Description

The present invention relates to a mortar stopper that plays a role as a mortar stopper when forming a basic decorative mortar on the outer surface of the foundation, and a method for constructing a building using the mortar stopper.

As a method of building a structure such as a wooden house, for example, after making a concrete foundation on the outer shell or inner shell of the part where the building is to be built, a base of wood is fixed on the upper surface of this foundation, There is a method of standing a pillar on the base and placing a beam on the pillar. Such a technique is a traditional Japanese architecture technique and is widely used in the construction of wooden houses.

Concrete foundations (cloth foundations) are made by mixing cement, sand, and water into a fluid or pre-assembled metal or wooden formwork and allowing them to solidify for a few days. Due to the characteristics of the concrete itself that contains and drains moisture in the long term, the wooden foundation absorbs moisture from the concrete foundation and makes it difficult to wet and dry at the contact area with the wooden foundation where the concrete foundation directly contacts. If the drying is inhibited, there is a problem that the wooden base is decayed over time.

Also, since there is no gap between the concrete foundation and the wooden base, it is not possible to ventilate between the two, but in wooden houses it is necessary to ventilate under the floor, For example, a ventilation hole having a length of about 200 mm and a width of about 400 mm has been formed in an appropriate portion of a concrete foundation. However, concrete foundations need to be strong enough to withstand the load of a wooden house, so it is difficult to form many such large ventilation holes. There were restrictions. For this reason, there is a problem that moisture tends to stay in a corner portion far from the ventilation hole in the underfloor space.

For this reason, there have been problems that the foundations and pillars have decayed over the years, and the foundations have been eaten by the termites. In addition, when a ventilation hole is formed in the concrete foundation, there is a problem that the concrete foundation is cracked from the corner of the ventilation hole due to the load of the wooden house.

The basic packing has been created to solve such problems. Foundation packing is provided between the foundation and the foundation, and has a long track record and is still used for the construction of wooden houses. In addition, the shape and material of the basic packing are described in detail in Patent Documents 1 to 3, which are the prior applications of the present applicant.

An example of the basic packing will be described with reference to the drawings.
FIG. 6 is a perspective view schematically showing an example of the basic packing.
The base packing 100 has three recesses 101 on the front and rear sides, and has a protrusion 102 and a recess 103 on the end in the longitudinal direction. The protrusion 102 and the recess 103 have a shape that allows male and female fitting. A groove 104 extending in the longitudinal direction for ventilation is formed on the surface of the base packing 100 that contacts the base. Further, the base packing 100 is formed with a hole 105 penetrating in the vertical direction. The hole 105 is for inserting an anchor bolt protruding upward from the concrete foundation. The base packing 100 has a length L of 200 mm, a width W of 100 mm, and a height H of about 20 mm.

Such a foundation packing is placed on the upper surface of a concrete foundation provided with anchor bolts. At the right corner of the concrete foundation, two foundation packings are placed in combination in a T-shape or L-shape. In the straight part of the concrete foundation, the foundation packing may be placed one by one, but the two foundation packings may be placed in the longitudinal direction as described above. Then, the base wood with the through holes of the anchor bolts is placed on the upper surface of the foundation packing, and the concrete foundation, the foundation packing, and the wooden base are fixed by screwing and tightening the nuts to the anchor bolts. be able to.

Conventionally, the foundation packing is not placed on the entire circumference of the upper surface of the concrete foundation, but is placed at a certain interval. As a result, the gap (height of about 20 mm) in the portion where the foundation packing is not placed can be used as a ventilation hole, so it is necessary to form a ventilation hole in the concrete foundation. Further, by interposing the foundation packing between the foundation and the wooden base, it is possible to prevent the wooden base from slipping and to have a highly earthquake-resistant structure.

According to this basic packing method, the ventilation of the building can be improved, the wooden base can be prevented from decaying, and termite erosion can be prevented, and the building can be solid and can be improved in earthquake resistance. Further, there is an advantage that the construction is simple and can be omitted.

FIG. 7 is a cross-sectional view showing an example of a building constructed using the above-mentioned basic packing method.
A foundation packing 100 is placed on the upper surface of the concrete foundation 200, and a wooden base 110 is placed thereon, and is fastened by screwing a nut onto an anchor bolt (not shown).
Further, since the foundation packing 100 is placed with a certain interval, the ventilation performance is improved. However, if it remains as it is, small animals such as sharks may come and go through this gap and eat the wooden base 110 and the like.

Therefore, usually, a large number of small rectangular holes that do not allow wrinkles to pass through the central part of the horizontally long steel plate are formed so as to be aligned in the longitudinal direction, and the steel plate is bent so that its cross section is in the shape of Z, A construction method is adopted in which a fender 240 is provided on the entire outer surface of a portion where a plurality of foundation packings 100 are placed, and a drainer 230 is disposed on the outer side thereof. When such a construction method is adopted, as shown in FIG. 7, mortar is applied to the entire outer side of the concrete foundation 200 with the same thickness (15 to 20 mm) as the lower part of the fender 240 and cured. A cosmetic mortar 220 was formed.
The fender 240 and the drainer 230 are fixed to the wooden base 110 by hitting them with nails, and the exterior material 210 is disposed thereon.

Thus, when the fender 240 is provided, the width of the lower part of the fender 240 serves as a reference for the thickness of the mortar layer and the upper end is regulated by the fender 240 when mortar is applied. The mortar may be formed with the lower part of the fender 240 as the upper end, and the basic decorative mortar 220 could be easily formed.

However, in recent years, the length of the basic packing is longer than that of the basic packing 100 shown in FIG. 6 (hereinafter also referred to as a short basic packing). For example, a long basic packing having a length L of about 900 mm is used. It has become. The reason is as follows.

That is, when such a long foundation packing is used, the number of parts does not increase even if it is placed so as to cover the entire circumference of the upper surface of the concrete foundation, and a short interval is provided at a certain interval on the upper surface of the concrete foundation. Compared with the case of mounting the basic packing, the positioning of the basic packing is not required, the construction becomes simpler, and further labor saving can be achieved.
If long foundation packing is used, alignment work is not required, so that the quality of construction can be made uniform, and the load of the wooden foundation is applied evenly over the entire area of the long foundation packing. Therefore, there is no possibility that the wooden base will be bent.

FIG. 8 is a perspective view schematically showing a state in which a long foundation packing is placed so as to cover the entire peripheral area of the upper surface of the concrete foundation. In the figure, 200 is a concrete foundation, 201 and 202 are rooms, 203 is an entrance area, and 302 is an anchor bolt.

As shown in FIG. 8, long foundation packings 300 and 301 are placed on the upper surface of the concrete foundation 200 so as to cover the entire circumference thereof. On the upper surface of the concrete foundation 200 that surrounds the entrance region 203, a solid foundation packing (hereinafter also referred to as a shielding-type foundation packing) 300 having no through-holes for ventilation is placed. Yes.
On the upper surface of the concrete foundation 200 that surrounds the areas 201 and 202 to be rooms, a foundation packing 301 (hereinafter also referred to as a ventilation-type foundation packing) 301 with a through-hole for ventilation formed on the side surface is placed. .

As shown in FIG. 8, when using a construction method in which a long foundation packing is placed so as to cover the entire circumference of the upper surface of a concrete foundation, a shielded foundation packing and a ventilation foundation packing are usually used. And both. This is due to the following reasons. In other words, in places where there is no underfloor and the indoor space and the external space are in contact on both sides via the base (for example, the entrance, the doorway, the soil part, etc.), it is not necessary to ventilate from the basic packing. Since the airtightness of the space is deteriorated and the cooling and heating efficiency is lowered, the shield-type basic packing is used. On the other hand, in other places, the foundation packing itself has a function as a ventilation hole by using a ventilation type foundation packing.

Japanese Utility Model Publication No. 54-181721 Japanese Utility Model Publication No. 54-181708 Japanese Patent Publication No. 55-40734

As described above, when using a construction method that places a long foundation packing so as to cover the entire circumference of the upper surface of the concrete foundation without any gaps, the through hole of the ventilation-type foundation packing can be Since the size is set so as not to pass, it is not necessary to provide the fender 240 (see FIG. 7).
However, in the construction method described above, since the fender 240 is not provided, when the foundation decorative mortar 220 is formed on the outer surface of the concrete foundation 200 as shown in FIG. The problem that it was difficult to apply mortar occurred.

FIG. 3 is a cross-sectional view for explaining the construction method of the building of the present invention using the decorative mortar fixing member of the present invention. In addition, since this construction method can be demonstrated comparatively easily, it shall be demonstrated using one drawing.

A cosmetic mortar stopper 10 according to the present invention is a cosmetic mortar stopper that plays a role as a cosmetic mortar stopper that regulates the height of a basic cosmetic mortar, and is a so-called long cosmetic mortar stopper. It is said to be.

“Regulating the height of the basic cosmetic mortar” means that when the basic cosmetic mortar is formed, the height of the basic cosmetic mortar is regulated to be no higher. Therefore, by using the decorative mortar stopper, when applying mortar, the upper end of the basic cosmetic mortar can be used as the lower surface of the decorative mortar stopper. Further, mortar can be applied using the width of the decorative mortar stopper as the reference for the width of the basic cosmetic mortar. That is, when the width of the decorative mortar stopper is the same as the width of the basic cosmetic mortar, the mortar can be applied so that the width (thickness) becomes the width of the decorative mortar stopper. .

The decorative mortar fixing member 10 according to the present invention includes a rectangular plate-like base fixing portion 11 for fixing to the outer surface of the base, a plate-like overhanging portion 12 protruding obliquely forward from the base fixing portion 11, and a tension. A rectangular plate-shaped decorative mortar stopper 13 is provided at the lower end of the protruding portion 12 so as to be substantially perpendicular to the base fixing portion 11. The protruding portion 12 has an opening 12a and a decorative mortar. The lower end of the overhang portion 12 is joined to the central portion of the stop portion 13.

Since this decorative mortar stopper 10 is long, as shown in FIG. 1, each member has a horizontally long shape.

Although the construction method of the building shown in FIG. 3 will be described in detail later, the base fixing part 11 is an outer surface of the base 40 provided on the base 30 shown in FIG. The fixing through holes 11a, which are members for fixing to 40a and are used when nails 41 are driven into the base 40, are provided at predetermined intervals. In addition, the method of fixing the base fixing | fixed part 11 to the base 40 is not restricted to the said method, You may fix by adhesion | attachment etc.

The overhanging portion 12 protrudes obliquely downward and forward from the base fixing portion 11.
This is because if the overhanging portion 12 is too close to the outer side surface 21 a of the foundation packing 20, air circulation through the air holes 25 of the foundation packing 20 may be impaired. That is, when the base fixing part 11 of the decorative mortar fixing member 10 is attached by projecting the overhanging part 12 obliquely forward and downward from the base fixing part 11 provided vertically, the overhanging part 12 and the foundation packing The distance with the outer side surface 21a of 20 is ensured, and the fall of the air permeability of the foundation packing 20 is prevented.
In addition, the lower end of the overhanging portion 12 is joined to substantially the center of the decorative mortar stopper 13 so that the rear end of the decorative mortar stopper 13 is located below the base fixing portion 11.

An opening 12 a is formed in the overhang portion 12. The size of the opening and the opening ratio are set so as not to impair the air flow through the vent hole 25 of the basic packing 20.
In this embodiment, the opening 12a of the overhanging portion 12 is set to be much larger than the opening of each vent hole 25 of the basic packing 20, and the arrangement state of the basic packing 20 is visually confirmed from the outside through this opening 12a. Can be done.

In the decorative mortar fixing member 10 shown in FIGS. 1 and 2, most of the overhanging portion 12 is opened except for a coupling portion 12 b having a slight width for connecting the base fixing portion 11 and the decorative mortar fixing portion 13. 12a is formed, and the air circulation through the vent hole 25 of the basic packing 20 is sufficiently secured.

When the base fixing part 11 is fixed to the base 40, the main surface of the base 40 becomes vertical, but the decorative mortar stopper 13 is provided perpendicular to the base fixing part 11, and the base fixing part 11 is the base. When fixed to 40, the main surface of the decorative mortar stopper 13 is in a horizontal state.

Further, the decorative mortar stopper 13 forms substantially the same plane as the upper surface 30 a of the foundation 30 when the base fixing part 11 is fixed to the base 40. For this reason, when forming the basic makeup mortar 50, the lower surface of the makeup mortar stopper 13 can be used as the upper surface of the foundation makeup mortar 50, and the width of the makeup mortar stopper 13 is defined as a reference for the width of the foundation makeup mortar 50. can do.

Further, since the lower end of the overhanging portion 12 is joined to the substantially central portion of the decorative mortar stopper 13, when the basic cosmetic mortar 50 is formed, the cosmetic mortar stopper 13 absorbs the force of the mortar-painting iron. It is easy, the makeup mortar stopper 13 is not easily inclined, the deformation of the makeup mortar stopper 10 as a whole can be prevented, and the basic makeup mortar 50 can be appropriately formed.

The “center portion of the decorative mortar stopper 13” may be inside if the front and rear ends of the decorative mortar stopper 13 are left, and the strength can be improved by moving closer to the center. This can absorb the power of the mortar and prevent the decorative mortar stopper 13 from being inclined.

The width of the decorative mortar stopper 13 is, for example, 15 to 20 mm. This is because when the basic cosmetic mortar 50 is formed on the outer surface of the foundation 30, the thickness is 15 to 20 mm, which is a reference when the mortar is set to this thickness.

The decorative mortar stopper 10 according to the embodiment is plate-shaped for easy weight reduction and easy carrying. Moreover, the opening part 12a of the overhang | projection part 12 is formed large for further weight reduction. Although the overall thickness of the decorative mortar retaining member 10 of the present invention is thin, the base fixing portion 11 and the overhanging portion 12 are bent at a predetermined angle α, and at the center of the decorative mortar retaining portion 13. Since the lower end of the overhanging portion 12 is joined, it is hardly deformed as a whole and has excellent mechanical strength.

The length of the decorative mortar stopper 10 is not particularly limited, but is preferably 500 to 2000 mm, for example. If the length of the decorative mortar fixing member 10 is made long, the width can be shortened by cutting it at the time of construction on site, so a longer one is desirable.

The material of the decorative mortar stopper 10 of the present invention is not particularly limited, and examples thereof include metal materials and resin materials. Although it does not specifically limit as a metal material, For example, stainless steel, cast iron, etc. can be mentioned. Ceramic may be used. The resin material is not particularly limited, and examples thereof include polypropylene, polyethylene, acrylonitrile / butadiene / styrene resin (ABS), polyvinyl chloride, and nylon. Examples of the resin material include rubber materials such as natural rubber (NR), styrene / butadiene rubber (SBR), and chloroprene rubber (CR). These materials may be used alone or in combination of two or more.

.
When using a resin material as a material for the decorative mortar stopper, it is desirable to add an inorganic material. This is because the rigidity becomes high and the hardness can be made suitable as a building material, the brittleness of the resin material due to light can be prevented, and the water resistance and heat resistance can be improved. The inorganic material is not particularly limited, and examples thereof include calcium carbonate, hydrous magnesium silicate, stone powder, concrete powder, blast furnace slag, fly ash and the like. The blending weight ratio between the resin material and the inorganic material is preferably 1: 0.1 to 1: 3. Further, for example, a plasticizer such as phthalate ester or dibutyl phthalate may be added. Moreover, a cheaper cosmetic mortar stopper can be provided by using waste materials or the like.

Next, the construction method of the building of the present invention using the decorative mortar fixing member of the present invention will be described.
The construction method according to the present invention is a construction method for a building in which a foundation packing and a base are sequentially provided on a foundation, and a decorative mortar stopper is provided on the foundation.

If a long foundation packing is used, the number of parts does not increase even if it is placed so as to cover the entire circumference of the upper surface of the concrete foundation, and a short foundation packing is placed on the upper surface of the concrete foundation with a certain interval. This is because the positioning of the foundation packing is not necessary as compared with the case of placing it, the construction becomes simpler, and further labor saving can be achieved. Moreover, it is because ventilation can be aimed at by using ventilation type basic packing, and the opening 12a formed in the overhang | projection part 12 of the decorative mortar stopper 10 can be utilized effectively.

FIG. 4 is a perspective view schematically showing an example of a long ventilation type basic packing, but the basic packing used in the present invention is not limited to the shape of the basic packing shown in FIG.
The basic packing 20 has a substantially rectangular plate shape having a predetermined thickness, and a pair of base bodies 21 and 22 extending in the long side direction and four places connecting the pair of base bodies 21 and 22 in the short side direction. Are formed integrally with each other. In addition, the connection part 23 is not restricted to four places, Three places or five places or more may be sufficient.

Use to fix.

After the above steps, mortar is applied to form the basic cosmetic mortar 50. At this time, the makeup mortar stopper 13 protrudes from the upper end of the foundation 30 and the width thereof is substantially the same as the thickness of the mortar, for example, 15 to 20 mm. Therefore, the surface of the foundation makeup mortar 50 is the tip of the makeup mortar stopper 13. What is necessary is just to form mortar so that it may become substantially the same as a part and the upper end may become the lower surface of the makeup | decoration mortar stop part 13. FIG. Therefore, the basic cosmetic mortar 50 can be easily formed.

Thereafter, a drainer 60 is usually provided so that water that has fallen due to rain or the like does not enter under the floor. At this time, the boundary between the base fixing part 11 and the overhanging part 12 of the decorative mortar stopper 10 is used as a mark when the drainer 60 is provided, and the part bent largely outward of the drainer 60 is connected to the base fixing part 11 and the overhanging part. The drainer 60 can be provided at an appropriate position by setting it to be the same as or slightly above the boundary with the portion 12.
