Description

The present invention relates to a construction method for a building in which a foundation packing is provided between a foundation and a foundation, and the building. In particular, the present invention relates to a construction method for a building in which a foundation packing is provided between a cloth foundation and a wooden base, and the building.

As a method of building a structure such as a wooden house, for example, a concrete foundation is made on the outer shell or inner shell of the part where the building is to be built, and then the ink is placed on the upper surface of the foundation for positioning the foundation. There is a method of drawing a line, fixing a timber base on the foundation based on the ink line, setting a pillar on the wooden 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, pouring them into a fluidized metal or wooden formwork, and allowing them to stand for several days to solidify. Since this formwork is installed in the field by combining a plurality of metal or wooden plates, it is difficult to install so that the alignment state of each plate at the time of installation is aligned. Therefore, it is common that waviness is generated at the side edge of the solidified concrete foundation. Therefore, by drawing a summing line on the upper surface of the concrete foundation, the wooden base is arranged at an accurate position with respect to the concrete foundation based on the marking line. In addition, as the inking line drawn on the top surface of the concrete foundation, for example, a heart ink for alignment with the center line of the wooden base, a relief ink drawn in parallel with a predetermined dimension away from the heart ink, etc. are used. It is done.

According to the technique of drawing the ink line and placing the wooden base in this way, even if waviness occurs on the side edge of the concrete foundation, instead of placing the wooden base on the basis of the wavy side edge, A concrete foundation that can accurately place a wooden base on the upper surface of a concrete foundation, based on the ink marking line showing an accurate straight line, while containing a large amount of moisture and discharging moisture in the long term. Due to its own characteristics, the wooden foundation absorbs the moisture of the concrete foundation at the site of contact with the wooden foundation where the concrete foundation comes into direct contact, making it difficult to wet and drying. If the wet foundation inhibits drying, the wooden foundation will decay over time. There was a problem to do.
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, under floors of conventional wooden houses cannot be adequately ventilated and moisture is easily trapped, and the wooden base absorbs moisture under the floor and moisture of the concrete foundation so that it is always moist. there were. For this reason, there has been a problem that the foundation will decay over the years. In addition, moisture and temperature suitable for termite breeding are kept under the floor, and there is also a problem that the base is devoured by termites. In addition, when there is poor ventilation, there is a problem that in addition to termites, decaying fungi propagate on the foundations and pillars, causing the foundations and pillars to decay. Furthermore, when the 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 a conventional basic packing will be described with reference to the drawings.
FIG. 5 is a perspective view schematically showing an example of a conventional 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.

When the protrusions 102 of one base packing 100 are fitted into the recesses 103 of the other base packing 100, the two base packings 100 can be joined in the longitudinal direction. Further, when the protrusions 102 of one foundation packing 100 are fitted into the recesses 101 of the other foundation packing 100, the two foundation packings 100 can be combined into a T-shape. In this way, the foundation packing 100 can be joined in the longitudinal direction or the front-rear direction and arranged on the surface of the concrete foundation.

Such a foundation packing is placed on the upper surface of the concrete foundation at the portion where the anchor bolt is provided. 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 having the through holes for 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. Of course, there is also a part where the foundation packing is simply placed on the upper surface of the concrete foundation.

Usually, 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, and the gap (height of about 20 mm) in the part where the foundation packing is not placed is ventilated. Use as a hole. Therefore, since it is necessary to form a ventilation hole in the concrete foundation by using the foundation packing, the foundation work can be saved, and the strength of the concrete foundation can be sufficiently maintained. Moreover, it is possible to prevent the skid of the wooden base and make a structure having high earthquake resistance. In addition, since the foundation packing is interposed between the concrete foundation containing moisture and the wooden base, moisture does not infiltrate the wooden base. Therefore, the wooden base is less susceptible to decay and termite erosion, and the durability of the wooden base is improved and the life of the wooden house can be extended.

Furthermore, since the foundation packing is placed on the upper surface of the concrete foundation with a certain interval, all of the inking lines drawn on the upper surface of the concrete foundation do not become invisible. Therefore, even if the foundation packing is placed on the upper surface of the foundation, it is possible to accurately align the wooden base with reference to the inking line.

Thus, the construction method using a foundation packing is called a foundation packing construction method. According to the foundation 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.

In recent years, various contrivances have been made for the basic packing, and one of them is a long basic packing. The long foundation packing has a longer length than the foundation packing 100 shown in FIG. 5 (hereinafter also referred to as a short foundation packing). For example, the length L is about 900 mm. According to the long foundation packing, 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.

Also, when placing a long foundation packing so as to cover the entire circumference of the top surface of the concrete foundation, compared to placing a short foundation packing at a certain interval on the top surface of the concrete foundation, It is not necessary to align the packing. Therefore, the construction becomes simpler and further labor saving can be achieved.
In addition, when placing short foundation packings with a certain interval on the top surface of the concrete foundation, there is a risk that the accuracy of alignment may vary depending on the technical ability of the contractor. When a long foundation packing is placed so as to cover the peripheral area, alignment work is not required, and the construction quality can be made uniform.
Furthermore, if a long foundation packing is placed so as to cover the entire circumference of the top surface of the concrete foundation, the load on the wooden foundation will be applied evenly over the entire area of the long foundation packing, so the wooden foundation will bend. There is also no risk of occurrence.

As described above, the construction method in which the long foundation packing is placed so as to cover the entire circumference of the upper surface of the concrete foundation has many advantages, and has been widely used in recent years.
FIG. 6 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. 6, 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. A solid foundation packing (hereinafter also referred to as a shield-type foundation packing) 300 having no through-holes for ventilation is placed on the upper surface of the concrete foundation 200 that surrounds the entrance region 203. 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. 6, 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 the concrete foundation, usually a shielded foundation packing and a ventilation foundation packing are 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.

However, as described above, the following problems may occur when using a construction method in which a long foundation packing is placed almost without any gap so as to cover the entire circumference of the upper surface of the concrete foundation. .

7A to 7C are perspective views schematically illustrating an example of a conventional construction method for a building.
First, inking line (running ink) 413 is drawn on the upper surface 411 of the concrete foundation 410 having a width of 120 mm (see FIG. 7A). The inking line 413 is separated from the wall surface 412 of the concrete foundation 10 by about 3 mm.

Next, the foundation packing 420 is placed on the upper surface 411 of the concrete foundation 410. The base packing 420 includes a base body 421 in which a plurality of bolt insertion holes 424 for inserting anchor bolts (not shown) are formed, and has a length of 910 mm, a width of 120 mm, and a height of 20 mm. When the foundation packing 420 is placed on the upper surface 411 of the concrete foundation 410 having a width of 120 mm, the ink marking line 413 is covered by the foundation packing 420, and the ink marking line 413 cannot be visually recognized (FIG. 7B). reference).

Thereafter, the wooden base 430 is placed on the foundation packing 420, and the concrete foundation 410 and the wooden base 430 are fixed by anchor bolts (not shown). Then, a mortar 440 is applied to the wall surface 412 of the concrete foundation 410 and the side surface 422 of the foundation packing 420 and cured, and a plate-like body (for example, plywood) that becomes a part of the exterior plate so as to be positioned above the mortar 440. Etc.) 450 is attached to the wooden base 430 (see FIG. 7C).

In this way, in the construction method shown in FIG. 7, the foundation packing 420 is placed so as to cover the entire circumference of the upper surface 411 of the concrete foundation 410. When placing 430, the inking line 413 cannot be visually recognized. Therefore, there is a problem that it is difficult to accurately position the wooden base 430 with reference to the ink marking line 413, and smooth construction cannot be performed.

It is considered that such a problem can be solved by arranging a plurality of narrow foundation packings on the upper surface 411 of the concrete foundation 410 with a predetermined interval, since the ink drawing line can be seen from between the foundation packings. However, when a narrow base packing is used, another problem as described below may occur.

8A to 8B are perspective views schematically showing another example of a conventional construction method for a building.
First, after drawing the ink marking line 413 on the upper surface 411 of the concrete foundation 410 having a width of 120 mm, the foundation packing 520 having a narrower width than the foundation packing 420 shown in FIG. (See FIG. 8A). The foundation packing 520 has the same shape as the foundation packing 420 shown in FIG. 7 except that the width of the base 521 is 102 mm. Since the foundation packing 520 has a narrow base 521, the foundation packing 420 can prevent the marking line 413 from being covered when the base packing 520 is placed on the upper surface of the concrete foundation 410 having a width of 120 mm.

Thereafter, the wooden base 430 is placed on the foundation packing 520, and the concrete foundation 410 and the wooden base 430 are fixed by anchor bolts (not shown). And the mortar 440 is apply | coated and hardened to the wall surface 412 of the concrete foundation 410, and the side surface 522 of the foundation packing 520, and the plate-shaped object 450 is attached to the wooden base 430 so that it may be located above the mortar 440 (FIG.8 (b). )reference).

In the construction method shown in FIG. 8, since the state where the inking line 413 can be visually recognized is maintained even when the foundation packing 520 is placed, accurate alignment of the wooden base 430 with respect to the inking line 413 is performed. It can be carried out.
However, in the case of the construction method using the narrow foundation packing 520, the upper surface 411 of the concrete foundation 410 is predetermined on the upper surface 411 of the concrete foundation 410 so that the foundation packing 520 can withstand the load of the house received from the wooden base 430 placed thereon. It is necessary to place the base packing 520 at a predetermined position with a gap. As for the precautions such as the mounting position and interval of the narrow foundation packing 520, manuals of construction methods and the like are distributed to the installers who provide the narrow foundation packing 520, and training is conducted. Although it encourages them to become familiar with the construction method, the problem of the influence of the skill level of the installer is undeniable.
Therefore, it has been proposed that the safety packing can be secured regardless of the skill level of the installer by placing the foundation packing on the entire circumference of the upper surface 411 of the concrete foundation 410 as described above. There is a problem that a new ink line cannot be visually recognized.

Further, it is difficult to accurately flatten the upper surface 441 of the mortar 440, and some unevenness is generated on the upper surface 441. Therefore, a plate based on the upper surface 441 of the mortar 440 is attached when the plate-like body 450 is attached. When the alignment of the state body 450 is performed, there is a problem that it is difficult to perform alignment accurately and smooth construction cannot be performed.

The present invention has been made in view of the above-described problems, and the object thereof is a method for constructing a building using a base packing that can easily perform accurate positioning of a base with reference to the ink marking line. And to provide buildings. Moreover, the objective of this invention is providing the construction method and building of a building using the foundation packing which can perform the exact position alignment of the exterior board or the plate-shaped body used as a part of an exterior board easily.

Here, the basic packing 20 will be described. The base packing 20 is composed of a rectangular plate-like base body 21 and the base body width _Wp is 120 mm. Although not shown, the base 21 has a length of 910 mm and a height of 20 mm. Further, a plurality of grooves 25 (depth D: 6 mm) penetrating in the vertical direction are formed on the long side outer surface 22 of the base body 21 (see FIG. 2).
In the figure, 23 is a bottom surface of the groove 25, and 24 is a bolt insertion hole for inserting an anchor bolt (not shown) suspended from the concrete foundation 10.

In the step (ii), the foundation packing 20 is placed on the upper surface 11 of the concrete foundation 10 so that the inking line 21 can be visually recognized from above via the groove 25 (FIGS. 1B and 2). reference). At this time, as shown in FIGS. 1B and 2, if the base packing 20 is placed so that the bottom surface 23 of the groove 25 is positioned above the marking line 21, the position of the base packing 20 is set. Matching becomes easy and construction can be made smoother.

Moreover, in 1st Embodiment, as shown in FIG.1 (b) and FIG. 2, the long side outer side surface 22 of the foundation packing 20 and the side surface 12 of the concrete foundation 10 are located on substantially the same plane. A foundation packing 20 is placed on the upper surface 11 of the concrete foundation 10. Such a construction method is generally referred to as outer surface construction. In addition, as a construction method for placing the foundation packing 20 on the upper surface 11 of the concrete foundation 10, there is, for example, a core construction in which the center line of the concrete foundation 10 and the center line of the foundation packing are aligned.
