The method of setting the foundation on it is taken. In addition, as a conventional underfloor ventilation method, there was a method of installing a notch in the cloth foundation and underfloor ventilation, but a method of installing underfloor ventilation by continuously using a base packing with a ventilation hole ( Cat ventilation system) is taken. In addition, anchor bolts for fixing the foundation are installed on the top end surface of the fabric foundation.However, since it will be a hindrance when laying the foundation packing, a through hole is provided in the foundation packing, and an arrangement plan is made in advance. A base packing has been proposed in which the anchor bolt and the base packing can be installed without interfering with each other by performing marking. (For example, see Patent Document 1)
Japanese Patent Application Laid-Open No. 2002-129662

  However, the work of installing the base packing and the base after the leveling and terrain adjustment of the top end surface of the fabric foundation with the leveling mortar and the leveling mortar hardened was a work requiring a very long time. In addition, the leveling and unevenness adjustment work of the leveling mortar is a work that requires very high accuracy, and in particular, in the method of continuously laying the base packing, accuracy is required for the entire fabric foundation. It took a long time and required skill. In addition, it is necessary to plan the placement of the anchor bolts in advance, and if the placement of the anchor bolts deviates from the position planned at the time of construction, and the anchor bolts and the base packing interfere with each other, the replacement of the base packing, Or it was necessary to provide a notch in the base packing.

  The present invention has been made in view of the above-described circumstances, and provides a method of improving the accuracy of installation and reducing the number of construction days for the installation of the base packing, and can be installed by this method. To provide a foundation packing with a ventilation hole and a foundation structure for ventilating a cat that can be laid without affecting the arrangement position.

In order to solve the above problems, the present invention proposes the following means.
The invention according to claim 1 is a method of laying a base packing interposed between a fabric foundation and a foundation, wherein a leveling mortar is placed on the top end surface of the fabric base, and the leveling mortar is Before the base packing is laid on the leveling mortar, the base packing is laid at a predetermined height by applying an external force to the base packing and sinking the leveling mortar. It is characterized by doing.

  According to the laying method of the base packing according to the present invention, the base packing can be laid in a state where the leveling mortar is not hardened, and the work for adjusting the height and unevenness required for accuracy when the leveling mortar is placed is performed. Since the curing period until it is omitted and hardened can be omitted, the number of construction days can be reduced.

  The invention according to claim 2 is the laying method of the base packing according to claim 1, wherein the base packing is laid at a predetermined height by applying vibration to the base packing and sinking the leveling mortar. It is characterized by that.

  According to the laying method of the base packing according to the present invention, since the height of the base packing is adjusted by sinking the leveled mortar by vibration, it becomes possible to adjust the height of the entire range in which vibration is transmitted, This is particularly effective when adjusting the height of the base packing laid continuously. In addition, the air and moisture inside the leveling mortar are released to the surface by vibration, and the leveling mortar is compacted, so that the density is increased and the degree of shrinkage after the leveling mortar is cured is also reduced. Furthermore, since moisture floats quickly, curing is accelerated. Further, by changing the vibration characteristics, the mortar can be gradually leveled and fine adjustment is possible.

  The invention according to claim 3 is a base packing that is interposed between a fabric foundation and a foundation and can be laid on an uncured leveling mortar on the cloth foundation, and is elongated. The plate has a through hole into which an anchor bolt can be inserted from the lower surface side to the upper surface side, and a groove that penetrates both ends in the width direction perpendicular to the longitudinal direction is long on the lower surface side with a space therebetween. A packing main body formed continuously in a direction and a bottom plate which is in contact with the lower surface of the packing main body and capable of forming a hole through which the anchor bolt is inserted are provided.

  According to the base packing according to the present invention, the groove formed in the packing body functions as a ventilation hole by laying the base packing in the longitudinal direction of the cloth foundation in accordance with the longitudinal direction of the cloth foundation. By continuously laying the base packing, a continuous ventilation hole is formed on the entire surface of the foundation. At this time, the anchor bolt protruding from the fabric foundation interferes with the base packing and hinders the laying. However, a hole is formed in the bottom plate, and the hole may be inserted into the through hole of the packing body. Further, the bottom plate of the base packing can seal the top end surface of the leveling mortar except for the portion where the hole is formed to interfere with the anchor bolt as described above. For this reason, when this foundation packing is laid on the top end surface of the uncured leveling mortar, it is possible to prevent the leveling mortar from flowing out due to rain during or after the laying operation.

  The invention according to claim 4 is characterized in that, in the base packing according to claim 3, the length in the width direction of the bottom plate is set larger than the length in the width direction of the packing body. Yes.

  According to the base packing according to the present invention, when the height is adjusted by laying on the uncured leveling mortar, even if the leveling mortar leaks from the side of the base plate of the base packing, the width of the bottom plate Since the length of the direction is long, there is no possibility that the ventilation hole formed by the groove of the packing body on the bottom plate is blocked by the leaked leveling mortar.

  The invention according to claim 5 is the base packing according to claim 3 or claim 4, wherein a plurality of through holes of the packing body are formed in the longitudinal direction, and the arrangement of the through holes is at the center in the longitudinal direction. It is characterized by being asymmetrical.

  According to the foundation packing according to the present invention, when the plurality of foundation packings are continuously laid in the longitudinal direction of the cloth foundation, the anchor bolt that interferes with the foundation packing has a hole formed in the bottom plate of the foundation packing. What is necessary is just to insert in the through-hole of this packing main body. In addition, when the anchor bolt is located between adjacent through holes in the packing body, the position of the through hole is shifted in the longitudinal direction of the fabric foundation by rotating the base packing by 180 °, so there is no need to move horizontally. The through hole can be adjusted to the position of the anchor bolt. Thereby, whatever the position of the anchor bolt is, a plurality of foundation packings can be continuously laid in the longitudinal direction of the fabric foundation without any gaps.

  The invention according to claim 6 is the foundation packing according to any one of claims 3 to 5, wherein the bottom plate is formed of a transparent member, and passes through the through hole of the packing body from above the foundation packing. It is possible to see through below the base packing.

  According to the base packing according to the present invention, when the base packing is laid on the leveling mortar, it is necessary to drill the bottom plate of the base packing at a position where the anchor bolt and the base packing interfere with each other. Since it is transparent, it can be drilled by checking the position where the anchor bolt is easily inserted at the actual work position. Also, when laying the base packing on the uncured leveling mortar and adjusting the height, the leveling mortar at the bottom of the base packing can be visually checked, so the leveling of the leveling mortar can be easily confirmed .

  According to a seventh aspect of the present invention, the foundation packing according to any one of the third to sixth aspects is laid continuously on the top end surface of the fabric foundation via the leveling mortar, and the top of the foundation packing. It is characterized in that the base is installed.

  According to the foundation structure according to the present invention, the foundation can be constructed with less construction days than before. Moreover, the under-floor ventilation of the cat ventilation system which installed the ventilation hole in the base packing part is realizable. In addition, since the foundation packing with continuous ventilation holes can be laid continuously and accurately, the load applied to the foundation is uniformly transmitted to the fabric foundation as a whole, and uniform underfloor ventilation is possible over the entire foundation. . Moreover, since load sharing and underfloor ventilation are possible on the entire surface of the fabric foundation, load calculation and ventilation flow rate calculation based on the layout plan of the base packing are not required.

  According to the present invention, since the base packing can be laid on the uncured leveling mortar, the number of working days can be reduced. Moreover, the base packing can be laid continuously with high accuracy by the laying method using vibration. Moreover, by using the foundation packing with a ventilation hole corresponding to this, the load concerning a foundation can be uniformly transmitted to a cloth foundation, and the uniform under-floor ventilation of a cat ventilation system can be implement | achieved.

FIG. 1 is a side view showing the whole foundation structure, FIG. 2 is a cross-sectional view showing the foundation structure, and FIG. 2 is an enlarged perspective view of a base packing laying portion. As shown in FIGS. 1 to 3, the foundation structure 1 includes a fabric foundation 3 installed on the ground 2, a leveling mortar 4 placed on the top end surface 3 a of the fabric foundation 3, and a leveling mortar 4. A base packing 5 having a ventilation hole 6 laid horizontally on the top end surface 4a of the base packing 5 and a base 7 made of wood on the top end surface 5a of the base packing 5 are provided. A pillar 8 is assembled on the base 7 to construct a building. A plurality of anchor bolts 9 projecting in the vertical direction are arranged in the longitudinal direction A of the fabric foundation 3 on the top end surface 3 a of the fabric foundation 3. The anchor bolt 9 penetrates the leveling mortar 4, the base packing 5, and the base 7, and protrudes on the top end surface 7 a of the base 7. The nut 10 and the washer 11 are fitted to the anchor bolt 9, the washer 11 is brought into contact with the top end surface 7 a of the base 7, and the nut 10 is tightened, whereby the base 7 passes through the base packing 5 and the leveling mortar 4. The cloth base 3 is fixed horizontally. Further, ventilation between the outside and the inside located in the width direction B of the fabric foundation 3 can be performed through the ventilation hole 6 of the base packing 5.

  Next, the details of the base packing 5 will be described. The details of the base packing 5 are shown in FIGS. 4 is a plan view, FIG. 5 is a side view, FIG. 6 is a front view, and FIG. 7 is a bottom view. 8 and 9 are perspective views of the base packing. FIG. 8 is a partial perspective view from above, and FIG. 9 is a partial perspective view from below. As shown in FIGS. 4 to 9, the base packing 5 is formed of a packing body 12 and a bottom plate 13. The packing main body 12 is an elongated substantially plate-like shape, and has a through hole 14 penetrating from the upper surface 12a to the lower surface 12b. A plurality of through-holes 14 are formed at regular intervals S continuously in the longitudinal direction C of the base packing 5. Further, the packing body 12 is formed with grooves 15 penetrating both ends in the width direction D perpendicular to the longitudinal direction C of the base packing 5 on the lower surface 12b side. A plurality of grooves 15 are formed continuously at a constant interval T in the longitudinal direction C, and a reinforcing member 16 is formed as a reinforcing means. Further, the upper surface 12a is roughened. The bottom plate 13 is an elongated, substantially plate-like shape similar to the packing body 12, and is formed of a transparent member. The upper surface 13a of the bottom plate 13 is in contact with the lower surface 12b of the packing body. With this bottom plate 13, the opening of the groove 15 of the packing body 12 is closed and the ventilation hole 6 is formed. Further, the length W13 of the bottom plate 13 in the width direction D is set to be larger than the length W12 of the packing body 12 in the width direction D. Further, the packing main body 12 and the bottom plate 13 are bonded or welded together, and are integrated as a base packing 5.

  As described above, a plurality of through-holes 14 penetrating the packing main body 12 are formed at a constant interval S in the longitudinal direction C, and the arrangement thereof is relative to the center of the base packing 5 in the longitudinal direction C. It is formed asymmetrically. Moreover, the convex part 17 and the recessed part 18 are formed in the both ends 5b of the longitudinal direction C of the base packing 5 so that the base packing 5 can be mutually fitted. The positional relationship between the convex portion 17 and the concave portion 18 is formed symmetrically with respect to the center in the longitudinal direction C of the base packing 5.

  Next, the laying method using this base packing 5 is demonstrated. 10 to 14 show a state where the mortar 4 and the base packing 5 are laid on the top end surface 3a of the fabric foundation 3. FIG. 15 to 17 show the positional relationship between the base packing 5 laid on the leveling mortar 4 and the anchor bolts 9 protruding from the fabric foundation 3 to the base packing 5. FIG.

  First, as shown in FIG. 10, the fabric foundation 3 is placed with anchor bolts 9 placed in advance, and after curing, the leveling mortar 4 is placed on the top end surface 3a of the fabric foundation 3 from which the mold has been removed. Put. At this time, the top end surface 4a of the leveling mortar 4 is placed higher than the reference line G having a predetermined height. Further, the flatness of the top end face 4a of the leveling mortar 4 is not so required at this point, and may be such that it does not fall over when the base packing 5 is laid.

  Next, the base packing 5 is laid on the top end face 4a of the uncured leveling mortar 4. 11, 12, and 15 to 17 show the laying state of the base packing 5. The base packing 5 is laid so that the longitudinal direction C of the base packing 5 coincides with the longitudinal direction A of the fabric foundation 3. When laying the base packing 5, as shown in FIG. 3, the anchor bolt 9 protruding from the fabric foundation 3 is inserted into the through hole 14 that penetrates the packing body 12, but the bottom plate 13 is provided with a through hole. Therefore, the tip 9a of the anchor bolt 9 is brought into contact with the lower surface 13b of the bottom plate 13 as shown in FIG. Since the bottom plate 13 is formed of a transparent member, in this state, the position of the anchor bolt 9 is confirmed through the through hole 14 from above the base packing 5, and a hole 19 is formed as shown in FIG. . From this hole 19, the anchor bolt 9 is inserted into the base packing 5, and the base packing 5 is laid as shown in FIG.

  In addition, when the position of the anchor bolt 9 is located between two adjacent through holes 14 as shown in FIG. 16, the base packing is laid as shown below. As shown in FIG. 17, the arrangement of the through holes 14 is asymmetric with respect to the center in the longitudinal direction C, and the arrangement of the convex portions 17 and the concave portions 18 that fit the base packings 5 is symmetrical. For this reason, the position of the through-hole 14 can be shifted by rotating 180 degrees, without moving the base packing 5 horizontally. As a result, the anchor bolt 9 can be inserted through the base packing 5 and laid. Moreover, since the position of the convex part 17 and the recessed part 18 does not change, the adjacent base packings 5 can be fitted. Thereby, the base packing 5 in which the continuous ventilation hole 6 is formed can be continuously laid regardless of the position of the anchor bolt 9. At this time, since the top end surface 4a of the leveling mortar 4 is higher than the reference line G, which is a predetermined height of the top end surface 4a, the top end surface 5a of the base packing 5 is also a predetermined height of the top end surface 5a. It is set higher than the reference line H.

  Next, as shown in FIG. 12, the vibration P is applied to the top end surface 5 a of the base packing 5 in a state where the base packing 5 is laid and the leveling mortar 4 is not cured. The vibration P is transmitted to the leveling mortar 4 through the base packing 5. By this vibration P, the leveling mortar 4 is compacted and spreads on the top end surface 3a of the fabric foundation 3 as shown in FIG. Due to this action, the leveling mortar 4 interposed between the base packing 5 and the fabric foundation 3 is filled between the base packing 5 and the fabric foundation 3 and subsidence occurs. As shown in FIG. The top end surface 5a of the packing 5 is lowered to the position of the reference line H having a predetermined height. Thereby, the base packing 5 can be laid at a predetermined position and height. At this time, as shown in FIGS. 2 and 3, the leveling mortar 4 spreads in the width direction B of the fabric foundation 3 on the top end surface 3 a of the fabric foundation 3, and the side portion 13 c of the bottom plate 13 and the side surface of the fabric foundation 3. There is a case where it starts out from 3b. In this case, since the width W13 of the bottom plate 13 is set to be larger than the width W12 of the packing body 12, there is no possibility of closing the ventilation hole 6 formed in the packing body 12. Further, the protruding mortar can be scraped off by using the side portion 13c as a ruler, and the side surface 4b of the leveling mortar 4 can be finished with a heel. Conversely, if the leveling mortar 4 does not sufficiently expand in the width direction B of the fabric foundation 3 and a gap is formed between the bottom plate 13 and the fabric foundation 3, the leveling mortar 4 is filled from the side surface 4b. The side surface 4b can be finished with the side portion 13c of the bottom plate 13 as a ruler. Alternatively, when the side surface 3b of the fabric base 3 is finished with the decorative mortar 20 as shown in FIGS. 2 and 3, if the base packing 5 is laid so that the side portion 13c of the bottom plate 13 protrudes from the side surface 3b of the fabric base 3, A decorative mortar 20 can be applied to the side surface 3b of the fabric base 3 using the side portion 13c of the bottom plate 13 as a ruler. For the reference line G of the leveling mortar 4 and the reference line H of the base packing 5, specifically, water thread, laser level, or the like is used.

  The method of sinking the base packing 5 by the vibration P can sink the entire range where vibration is transmitted, compared to the method of adjusting the height adjustment point by hitting, pressing, or the like one by one. Thus, the present embodiment is suitable for the present embodiment in which it is laid uniformly. Further, since the air and moisture inside the leveling mortar 4 are released to the surface by the vibration P, and the leveling mortar 4 is compacted, the density is increased, and the degree of shrinkage after the leveling mortar 4 is cured is also reduced. Furthermore, since moisture floats quickly, curing is accelerated. Therefore, by adjusting the height by the vibration P, the quality of the leveling mortar 4 can be improved and the work period until curing can be shortened. Moreover, since the speed of sinking can be easily adjusted by changing the characteristics of the vibration P, the height of the base packing 5 can be adjusted with high accuracy.

  Further, the bottom plate 13 of the base packing 5 is transparent, and the lower part of the base packing 5 can be visually observed through the through hole 14 of the packing body 12. For this reason, as shown in FIG. 14, when the height of the base packing 5 is adjusted by the vibration P, the filling state of the leveling mortar 4 can be confirmed, so that the quality of the leveling mortar 4 can be ensured. Further, the bottom plate 13 of the base packing 5 can seal the top end surface 4a of the leveling mortar 4 except for the portion where the hole 19 is formed to interfere with the anchor bolt 9 as described above. For this reason, when this foundation packing 5 is laid on the top end surface 4a of the uncured leveling mortar 4, it is possible to prevent the leveling mortar 4 from flowing out due to rain during or after the laying operation.

  In this way, the above-described method of laying the base packing 5 and the base packing 5 in which the corresponding continuous ventilation holes 6 are formed are used, and the base packing 5 is continuously laid, thereby reducing the number of conventional packings. In the construction days, the load applied to the base 7 is uniformly transmitted to the cloth foundation 3, and the cat-ventilation-type foundation structure capable of uniform ventilation over the entire foundation is accurately realized.

In addition, although the convex part 17 and the recessed part 18 were provided in the both ends 5b of the longitudinal direction C of the base packing 5 so that the base packing 5 may mutually be fitted, it is not restricted to this but also by the method of connecting with a clip etc. As long as it does not have to be misaligned, a through hole may be provided in the base packing and nailed to the fabric foundation.
Further, the lower surface 13b of the bottom plate 13 is provided with protrusions or irregularities, so that the adhesion with the leveling mortar 4 becomes good, and the lateral displacement of the base packing can be prevented.
In addition, the base packing 5 is formed by bonding the packing main body 12 and the bottom plate 13 together, but may be separated.

  Next, FIGS. 18 to 20 show a second embodiment according to the present invention. This embodiment shows a conventional method for laying a base packing. As shown in FIG. 18, the leveling mortar 4 is placed at each position where the base packing 21 is laid on the top end surface 3 a of the fabric foundation 3. At this time, similarly to the first embodiment, the top end surface 4a of the leveling mortar 4 is placed higher than the reference line G having a predetermined height.

  Next, as shown in FIG. 19, the base packing 21 is laid on the top end face 4 a of the uncured leveling mortar 4. In this state, vibration P is applied to the top end face 21 a of each base packing 21. As in the first embodiment, the vibration P is transmitted to the leveling mortar 4 via the base packing 21, and the leveling mortar 4 sinks. Then, as shown in FIG. 20, the top end surface 21a of the base packing 21 is lowered to the position of the reference line H having a predetermined height. Thereby, the base packing 21 can be laid at a predetermined position and height.

  In this way, the method of laying the base packing on leveling mortar that has not yet hardened and adjusting the height can reduce the number of work days and improve the laying accuracy even if it is used in the base packing of various shapes. Can be planned.

  In the first and second embodiments, vibration is applied as a method for adjusting the height of the base packing. However, the present invention is not limited to this, and the height may be adjusted by a method such as striking or pressing. good.
