Description

  The present invention relates to a foundation packing device that is interposed between foundation concrete and a base and enables underfloor ventilation of, for example, a wooden building.

  This type of basic packing device includes a long rectangular packing body, and this packing body has a number of ventilation openings that open on both side surfaces thereof (see, for example, FIG. 2 of Patent Document 1). These ventilation openings are arranged at intervals in the longitudinal direction of the base packing, and the under floor ventilation is possible by connecting the under floor of the building to the outside air through the inside of the packing main body.

  According to such a foundation packing device, since it is not necessary to provide a ventilation opening in the foundation concrete itself, not only can the strength of the foundation concrete be ensured, but direct contact of the foundation with the foundation concrete is avoided, It is possible to prevent the decay of the foundation due to moisture.

JP 2009-221813

  By the way, in the case of the above-mentioned basic packing apparatus, since the original purpose is underfloor ventilation, the ventilation opening of the packing main body is secured relatively large. For this reason, although a ventilation port can prevent underfloor invasion of small animals, such as a rabbit, it cannot prevent underfloor invasion about insects, such as a smaller bee.

  In addition, the packing body has a bolt insertion slot that allows loose insertion of the anchor bolt protruding from the foundation concrete. This bolt insertion slot is larger than the diameter of the anchor bolt, so The packing body cannot be firmly fixed.

  The first object of the present invention is to provide a basic packing device that is excellent not only in its original underfloor ventilation but also in anti-insect measures, and the second object is to an anchor bolt. An object of the present invention is to provide a basic packing device that can also fix the packing body of the above.

  The above-mentioned first object is achieved by the basic packing device of the present invention, which has a longitudinal axis and has a rectangular packing body having a top wall and a peripheral wall extending along the outer periphery of the top wall. The outer wall of the packing body is formed on each of the side walls along the longitudinal axis of the packing body, and communicates with the outside air through the inside of the packing body, while maintaining a predetermined distance along the direction of the longitudinal axis. A large number of vents arranged side by side, and the vents open on the outer surface of the side wall with an opening width along the longitudinal axis of the insect-proof specification (claim 1), specifically, the opening width is 5 mm. (Claim 2)

  According to the basic packing apparatus of the present invention, since the opening width of the ventilation opening in the packing body is an insect-proof size, that is, 5 mm or less, insects such as bees pass through the packing body from the ventilation opening. There is no entry under the floor.

  The second object described above is a long shape that is formed on the upper wall of the packing body at intervals along the longitudinal axis, allows loose insertion of anchor bolts protruding from the foundation concrete, and extends along the longitudinal axis. It can be installed at any position along the longitudinal direction of the bolt loose insertion opening and at least one bolt loose insertion opening selected from these bolt loose insertion openings. This is achieved by a basic packing device (Claim 3) further comprising a cylindrical anchor adjuster having a bolt insertion hole allowing insertion of the anchor bolt.

  According to the basic packing device of the third aspect, the anchor body is connected to the anchor bolt by simply inserting the anchor bolt into the bolt insertion hole of the anchor adjuster and then mounting the anchor adjuster on the bolt loose insertion port of the packing body. That is, it is fixed.

Specifically, the anchor adjuster can have two bolt insertion holes having different inner diameters. In this case, the basic packing device of the present invention can be applied to anchor bolts having different diameters.
Furthermore, the packing body of the present invention can further include an elastic tongue piece, which is formed on the upper wall of the packing body and protrudes from the upper wall, while being elastically deformable to be immersed in the packing body. (Claim 5).

When the packing body is interposed between the foundation concrete and the base, the elastic tongue piece is elastically deformed and is immersed in the packing body. For example, even if the base is made of wood and the base is thin, the elastic tongue protrudes from the upper wall of the packing body by elastic restoring force following the thinness. Therefore, the frictional engagement between the base and the packing body is maintained by the elastic tongue regardless of the thinness of the base.
Furthermore, the basic packing device of the present invention may further comprise a coupling means for allowing the packing bodies to be coupled along the longitudinal axis or in a direction perpendicular to the longitudinal axis (Claim 6). Enables laying of the packing body according to the layout of the foundation concrete.
Further objects and advantages of the present invention will become apparent from the accompanying drawings and the following description.

  According to the basic packing device of the present invention according to claims 1 to 6, since the ventilation opening of the packing body has an opening width of insect-proof specification, insects such as bees are prevented from entering under the floor of the building. In addition, the anchor bolt can be coupled to the anchor bolt via the anchor adjuster.

  Referring to FIG. 1, an application example of a foundation packing apparatus 10 according to the present invention is shown, and this foundation packing apparatus 10 is interposed between a foundation concrete Bc and a wooden base Wd of a wooden building, for example. . An anchor bolt Ba protrudes upward from the foundation concrete Bc. The anchor bolt Ba penetrates the foundation packing device 10 and the wooden base Wd, and the wooden base via the washer Z and the nut N on the upper surface of the wooden base Wd. It is fastened to Wd.

  In FIG. 1, two foundation packing devices 10 are shown. These foundation packing devices 10 are arranged adjacent to each other in the longitudinal direction of the wooden base Wd and are coupled to each other. In addition, the basic packing apparatus 10 can perform not only the cascade connection shown in the figure but also the T-shaped connection, and the column connection and the T-shaped connection will be apparent from the following description.

  The foundation packing device 10 includes a packing body 12 sandwiched between the foundation concrete Bc and the wooden base Wd as a main part, and FIG. 2 is a plan view of a part of the packing body 12 in one embodiment.

The packing body 12 is integrally molded from a synthetic resin such as polypropylene, and has a long rectangular shape with a longitudinal axis A. In the case of this embodiment, the packing body 12 has a length of 900 mm and a width of 100 mm. In FIG. 2, the portion on the left side from the breaking line indicates the upper surface 12 _U of the packing body 12, while the portion on the right side from the breaking line indicates the lower surface 12 _L of the packing body 12.

Specifically, the packing body 12 includes an upper wall 14 that forms an upper surface 12 _U , and a peripheral wall that protrudes downward from the outer periphery of the upper wall 14 and extends along the outer periphery, and the peripheral wall extends along the longitudinal axis A. And a pair of end walls 18a and 18b orthogonal to the longitudinal axis A. The upper wall 14, the side wall 16, and the end walls 18 a and 18 b define a cavity 20 in the packing body 12, and the cavity 20 opens at the lower surface 12 _L of the packing body 12. Note that the end walls 18 a and 18 b have a width larger than the width of the side wall 16.

A large number of ventilation holes 22 are formed in each side wall 16, and these ventilation holes 22 are arranged along the longitudinal axis A with a predetermined pitch P as shown in FIG. 3. Specifically, the ventilation ports 22 open on the inner and outer side surfaces of the corresponding side wall 16, and alternately open on the upper surface 12 _U of the packing body 12 and the lower surface of the side wall 16 along the longitudinal axis A. Further, the ventilation port 22 opened at the upper surface 12 _U extends beyond the width of the side wall 16 (see FIG. 2).

Further, the upper wall 14 of the packing body 12 is formed with a number of grooves 24 at both side edges. These grooves 24 are arranged along the longitudinal axis A at a predetermined interval, open at the side edge of the upper wall 14, and extend in the width direction of the packing body 12.
The ventilation port 22 described above allows the underfloor of the wooden building to communicate with the outside air through the cavity 20 of the packing body 12 to realize underfloor ventilation.

The ventilation port 22 also exhibits an insect-proof function in addition to the underfloor ventilation function. Specifically, the width of the ventilation port 22 that opens on the inner and outer side surfaces of the side wall 16, that is, the opening width W _V of the ventilation port 22 along the longitudinal axis A is limited to the size of the insect-proof specification that prevents intrusion of bees and the like. ing. Specifically, the opening width W _V is preferably as narrow as possible from the viewpoint of insect prevention, but is preferably 5 mm or less in consideration of the moldability of the ventilation port 22. In the case of this embodiment, the opening width W _V is set to 3 mm.

Thus, if the opening width W _V of the ventilation port 22 is narrow, insects such as bees will not enter the floor of the wooden building through the inside of the packing body 12, and the wooden building will be damaged by insects such as bees. There is no.

  On the other hand, a pair of coupling claws 26a project from the end wall 18a of the packing body 12, and these coupling claws 26a are separated from each other by a predetermined distance L in the width direction of the packing body 12 as shown in FIG. doing. A pair of fitting grooves 28 b are also formed in the end wall 18 a, and these fitting grooves 28 b are also separated from each other by a distance L in the width direction of the packing body 12. On the other hand, as shown in FIG. 4B, the end wall 18b of the packing body 12 has a pair of fitting grooves 26b corresponding to the pair of coupling claws 26a and a pair corresponding to the pair of fitting grooves 28b. The coupling claws 28a are respectively formed.

  Therefore, with respect to the two basic packing devices 10 shown in FIG. 1, the packing bodies 12 of these devices 10 abut the end wall 18 a of one packing body 12 and the end wall 18 b of the other packing body 12. At this time, the pair of coupling claws 26a of the end wall 18a are fitted into the fitting grooves 26b of the end wall 18b, and at the same time, the pair of coupling claws 28a of the end wall 18b are fitted into the fitting grooves 28b of the end wall 18a. By doing so, they are integrally connected in cascade.

  Further, the end walls 18a and 18b of the packing body 12 are formed with a pair of communication ports 30a and 30b on both sides of the longitudinal axis A, respectively. When the packing bodies 12 are abutted with each other as described above, The communication ports 30a respectively match the pair of communication ports 30b, whereby the cavities 20 between the packing bodies 12 communicate with each other through the communication ports 30a and 30b.

Thus, if the cavities 20 of the adjacent packing bodies 12 communicate with each other, the ventilation paths can be overlapped.
Further, with regard to the coupling claws 26a and 28a, the aforementioned interval L is set to an integral multiple of the pitch P at the ventilation port 22, while the coupling claws 26a and 28a have a size that can be inserted into the ventilation port 22. Therefore, when the end wall 18a (or 18b) of the other packing body 12 is abutted against the side wall 16 of the one packing body 12, the coupling claw 26a (or 28a) is inserted into the ventilation port 22 of the side wall 16 to thereby seal the packing. The main bodies 12 can be integrally T-coupled.

  Even in such a T-shaped connection, the communication port 30a of the end wall 18a (or the communication port 30b of the end wall 18b) matches the corresponding ventilation port 22. Therefore, the cavities 20 of the packing body 12 that are T-coupled also communicate with each other, and the ventilation paths can be overlapped. In addition to the communication ports 30a and 30b, two more communication ports 30c can be formed on the end walls 18a and 18b of the packing body 12 as shown in FIG. Moreover, it corresponds to the corresponding ventilation port 22 at the time of T-shaped coupling.

  Further, since the ventilation port 22 of the side wall 16 and the communication ports 30a, 30b, and 30c of the end walls 18a and 18b give the packing body 12 flexibility and compressibility, even if the upper surface of the foundation concrete Bc is not flat. The packing body 12 is allowed to warp, twist, bend or compress following the upper surface of the foundation concrete Bc, and can adhere well to both the foundation concrete Bc and the wooden base Wd.

  On the other hand, as shown in FIG. 2, a large number of bolt insertion holes 32 are formed in the upper wall 14 of the packing body 12, and these bolt loose insertion holes 32 communicate with the cavity 20, while having a predetermined length along the longitudinal axis A. Arranged at intervals. Specifically, the adjacent bolt insertion holes 32 are arranged so as to be displaced in the opposite directions from the longitudinal axis A when viewed in the width direction of the packing body 12.

  The bolt loose insertion port 32 has a rounded rectangular shape extending along the longitudinal axis A, and the anchor bolt Ba described above is anchored with sufficient play in the longitudinal direction (the direction of the longitudinal axis A) and the width direction of the packing body 12. It has a size that allows the insertion of the bolt Ba. As shown in FIG. 5, the opening edge of the bolt loose insertion opening 32 is formed as an inclined surface facing upward, that is, a receiving seat 34, and an anchor adjuster described later can be seated on the receiving seat 34.

  Further, a pair of elastic tongues 36 are integrally provided from the upper wall 14 of the packing body 12 between the adjacent bolt insertion holes 32. These elastic tongue pieces 36 are arranged so as to be equidistant from the longitudinal axis A and to have their tips directed outward in the width direction of the packing body 12.

Specifically, the elastic tongue 36 is obtained by forming a U-shaped through-hole in the upper wall 14 and protrudes upward from the upper wall 14 as shown in FIG. 6 when in a free state. A cut groove is formed in the inner surface of the base of the elastic tongue piece 36, and the cut groove forms the root of the elastic tongue piece 36 in the self hinge 37. Therefore, when the wooden base Wd is placed on the packing body 12, the elastic tongue 36 is elastically deformed so as to rotate around the self hinge 37 as shown by a two-dot chain line in FIG. 12, that is, the upper wall 14 is immersed.
However, when the wood base Wd is thinned, the elastic tongue piece 36 projects from the upper wall 14 of the packing body 12 by an elastic restoring force following the thinning of the wood. Therefore, the elastic tongue piece 36 maintains the frictional engagement with the wooden base Wd regardless of the thinness of the wooden base Wd, and the packing body 12 does not move undesirably with respect to the foundation concrete Bc and the wooden base Wd. Absent.

7 and 8 show a part of the packing body 12 in perspective views, and the configuration of the packing body 12 described above from these perspective views, that is, the ventilation port 22, the coupling claw 26a, the bolt loose insertion port 32, and the like. The shape and arrangement of the are made clearer.
As shown in FIG. 7, a large number of side ribs 38 are integrally provided in the vicinity of the side walls 16 on the inner surface of the upper wall 14 of the packing body 12, and these side ribs 38 are formed along a longitudinal axis A with a predetermined length. It arrange | positions at intervals and is connected to the lower part of the side wall 16 through the connection part. Therefore, the side ribs 38 reinforce the corresponding side wall 16.

Further, a large number of center ribs 40 are also integrally formed on the inner surface of the upper wall 14, and these center ribs 40 are more clearly shown in FIG. It is positioned in the center when viewed in the width direction and extends in the width direction.
Needless to say, the side ribs 38 and the center ribs 40 have the same height as the side walls 16 and the end walls 18a and 18b.

  Referring to FIG. 9, an anchor adjuster 42 attached to one of the bolt loose insertion openings 32 is shown, and the anchor bolt Ba described above extends through the anchor adjuster 42. The anchor adjuster 42 is molded from polypropylene like the packing body 12 and has a cylindrical shape.

  Such an anchor adjuster 42 has a size that can be fitted into the bolt loose insertion port 32 from above, but its diameter is sufficiently smaller than the length of the bolt loose insertion port 32 along the longitudinal axis A. Therefore, the anchor adjuster 42 can be attached to the bolt loose insertion slot 32 at an arbitrary position as viewed in the length direction of the bolt loose insertion slot 32.

  Specifically, as apparent from FIG. 10, the anchor adjuster 42 has an upper portion 44, an intermediate portion 46, and a lower portion 48, and the outer peripheral surface of the upper portion 44 is formed as a tapered surface 50 that decreases in diameter downward. . The taper surface 50 has a size that matches the seat 34 of the bolt insertion slot 32. Therefore, the anchor adjuster 42 has the taper surface 50 of the upper portion 44 supported by the seat 34 and the bolt play. The upper surface of the anchor adjuster 42, that is, the upper surface of the upper portion 44 is flush with the upper surface of the upper wall 14 of the packing body 12.

  The intermediate portion 46 has a tube shape slightly smaller in diameter than the upper portion 44, and the lower portion 48 has a tapered tube shape whose diameter decreases from the lower end of the intermediate portion 46 downward. Further, notches 52 and 54 are formed at the lower end of the lower portion 48, and these notches 52 and 54 extend from the lower end of the lower portion 48 to the lower end of the intermediate portion 46. The notches 52 and 54 are separated from each other in the radial direction of the anchor adjuster 42, and the width of the notch 54 is wider than the width of the notch 52 in the circumferential direction.

  As shown in FIG. 12, two circular bolt insertion holes 56 and 58 are formed on the upper surface of the upper portion 44, and the bolt insertion hole 56 is positioned on the notch 52 side, while the bolt insertion hole 58 is on the notch 54 side. It is positioned. That is, the bolt insertion holes 56 and 58 are positioned eccentric from the center of the anchor adjuster 42. The bolt insertion hole 58 has a larger diameter than the bolt insertion hole 56, and the inner diameters of these bolt insertion holes 56, 58 are generally set according to the shaft diameter of the anchor bolt Ba having a different diameter.

The bolt insertion hole 58 has an inner diameter corresponding to, for example, a thick anchor bolt Ba having a shaft diameter of 16 mm, and a shaft portion of the anchor bolt Ba can be fitted therein. On the other hand, the bolt insertion hole 56 has a shape and an inner diameter corresponding to, for example, a thin anchor bolt Ba having a shaft diameter of 12 mm. As is apparent from FIG. 12, the bolt insertion hole 56 has, for example, a shape in which large and small insertion holes are partially overlapped, and has a large diameter portion 56a and a small diameter portion 56b. The small diameter portion 56b has an inner diameter for fitting the shaft portion of the thin shaft anchor bolt Ba, while the large diameter portion 56a has an inner diameter that allows the thread portion to be inserted into the thin shaft anchor bolt Ba.
Accordingly, when the anchor adjuster 42 is attached to the thin anchor bolt Ba, the anchor bolt Ba is first inserted into the large diameter portion 56a of the bolt insertion hole 56, and then fitted to the small diameter portion 56b.

In the intermediate portion 46, the bolt insertion hole 56 is continuous with the insertion pipe 60, while the bolt insertion hole 58 is continuous with the insertion pipe 62. The inner diameters of these insertion pipes 60, 62 are the inner diameters of the bolt insertion holes 56, 58. Is equal to Further, a pair of biting studs 64 is formed on the upper surface of the upper portion 44. These biting studs 64 have a conical shape and are spaced from each other in the radial direction of the upper portion 44 between the bolt insertion holes 56 and 58.
FIG. 13 shows a part of the anchor adjuster 42 in a perspective view, and the internal configuration of the anchor adjuster 42 becomes clearer from this perspective view.

As shown in FIG. 9, in the case of the present embodiment, the thick anchor bolt Ba passes through the large-diameter bolt insertion hole 58 and the insertion tube 60 of the anchor adjuster 42, whereby the packing body 12 moves the anchor adjuster 42. Via the anchor bolt Ba.
Here, as shown in FIG. 10, the upper surface of the anchor adjuster 42 is flush with the upper surface of the packing main body 12, so that when the wooden base Wd is placed on the packing main body 12, the pair of anchor adjusters 42 The biting stud 64 bites into the lower surface of the wooden base Wd. Therefore, the wooden base Wd is also coupled to the packing body 12 via the anchor adjuster 42.

  As described above, the anchor adjuster 42 can be mounted on the bolt loose insertion port 32 at an arbitrary position as viewed in the longitudinal direction of the bolt loose insertion port 32 (in the direction of the longitudinal axis A), while the bolt insertion hole of the anchor adjuster 42 is provided. 58 (insertion tube 62) is eccentrically positioned, and if the anchor adjuster 42 is rotated relative to the bolt loose insertion port 32, the position of the bolt insertion hole 58 (insertion tube 62) is the bolt loose insertion port. It can be displaced in 32 width directions (direction orthogonal to the longitudinal axis A).

  Therefore, the anchor bolt Ba is inserted into the bolt insertion hole 58 (insertion tube 62) by adjusting the mounting position of the anchor adjuster 42 with respect to the bolt loose insertion port 32 and the rotation posture thereof according to the protruding position of the anchor bolt Ba. In this state, the anchor adjuster 42 can be easily attached to the bolt insertion slot 32. The same applies to the case where a thin anchor bolt is inserted into the bolt insertion hole 56 (insertion tube 60) of the anchor adjuster 42.

Furthermore, even if the protruding position of the anchor bolt Ba is greatly deviated from the normal position so that it cannot be dealt with only by the eccentricity of the anchor adjuster 42, in this case, if the packing main body 12 is reversed and installed on the foundation concrete Bc. As described above, the bolt loose insertion holes 32 arranged in the longitudinal direction of the packing body 12 are arranged in a staggered manner, so that it is possible to cope with them.
As a result, according to the foundation packing apparatus 10 of this embodiment, the foundation packing apparatus 10 can be easily interposed between the foundation concrete Bc and the wooden base Wd.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, the opening width of the ventilation port 22 may be narrower than 3 mm, and the insect-proof ventilation port may be provided at least on the outer side wall 16 of the packing body 12.
In addition, the anchor adjuster 42 may have either one of the bolt insertion holes 56, 58, or another bolt insertion hole having a different inner diameter in addition to the bolt insertion holes 56, 58, and the like. These specific configurations and materials can be modified as appropriate.

Furthermore, in the embodiment, the elastic tongue piece 36 described above has a rectangular shape, but is not limited to this rectangular shape, and may have a triangular shape as shown in FIG.
On the other hand, as shown in FIG. 14, the basic packing device 10 can be used even in combination with a pair of seal plates 70. These seal plates 70 are removably attached to the inner and outer side walls 16 of the packing body 12 in order to hermetically close the ventilation ports 22 of the side walls 16.

  Specifically, as shown in FIGS. 15 and 16, the seal plate 70 includes an elongated plate body 72, and the plate body 72 has the same length and height as the side wall 16. A plurality of insertion pins 74 project from the inner surface of the plate body 72, and these insertion pins 74 are arranged at intervals in the longitudinal direction of the plate body 72. Therefore, it is possible to easily attach the plate body 72 to the side wall 16 by inserting the insertion pins 74 into the ventilation ports 22 of the side wall 16 so that the plate body 72 is attached to the side wall 16 of the packing body 12. The ventilation port 22 of the side wall 16 is covered by the plate body 72 in a lump.

Further, as shown in FIG. 17, seal pads 76 are attached to the upper and lower edges of the plate body 72, respectively. These seal pads 76 extend in the longitudinal direction of the plate main body 72, and when the plate main body 72 is attached to the side wall 16, the seal pads 76 are in close contact with the side wall 16, respectively, thereby improving the closing property of the ventilation port 22, that is, the sealing property.
The foundation packing device 10 combined with the pair of seal plates 70 described above is installed on the foundation concrete Bc that divides the bathroom, prevents moisture in the bathroom from leaking to the outside, and cool air from the outside under the bathroom floor. Demonstrate the function to penetrate.

On the other hand, as shown in FIG. 18, the foundation packing device 10 of the present invention can include a construction auxiliary tool 78, which not only lays the packing body 12 but also mortar finishes of the basic concrete Bc. Useful for ease.
Specifically, the construction aid 78 includes a plate body 80. The plate body 80 has a length similar to that of the side wall 16 of the packing body 12, but its height is lower than that of the side wall 16.

An outer rib 82 and an inner rib 84 project from the lower surface of the plate main body 80, and the outer rib 82 and the inner rib 84 extend along the entire length of the plate main body 80 and extend in parallel to the longitudinal direction of the plate main body 80. Form.
As apparent from FIG. 18, the outer rib 82 is positioned at one side edge of the plate body 80, while the inner rib 84 is positioned at the center of the plate body 80 when viewed in the width direction of the plate body 80.

  Further, a plurality of insertion pieces 86 are erected on the upper surface of the plate body 80, and these insertion pieces 86 are formed integrally with the plate body 80. As is apparent from FIGS. 19 and 20, the insertion pieces 86 are spaced from each other in the longitudinal direction of the plate body 80, and extend from the plate body 80 to the other side edge of the plate body 80 in the longitudinal direction of the plate body 80. It extends in the direction orthogonal to.

  The distal end portion 86 a of the insertion piece 86 protruding from the plate main body 80 has a lower edge that is flush with the lower surface of the plate main body 80, and has a height and width that can be inserted into the ventilation port 22 of the packing main body 12. On the other hand, although the base end portion 86b of the insertion piece 86 has the same width as the tip end portion 86a, the height of the base end portion 86b from the lower surface of the plate body 80 is higher than the thickness of the packing body 12. Therefore, the insertion piece 86 can be inserted into the ventilation port 22 only by the tip end portion 86a.

The construction assisting tool 78 described above is used as follows.
First, as shown in FIG. 18, the construction auxiliary tool 78 is arranged in a state where the other side edge of the plate body 80 is placed on the upper surface of the foundation concrete Bc and the inner rib 84 is pressed against the outer surface of the foundation concrete Bc. . That is, the construction auxiliary tool 78 is disposed so as to reach the outer corner of the upper surface of the foundation concrete Bc.

In this state, the packing body 12 is disposed on the upper surface of the foundation concrete Bc, and the packing body 12 is directed toward the base end portion 86b of the insertion piece 86 until the distal end portion 86a of the insertion piece 86 is completely received in the insertion opening 22. Pressed. In this case, as shown in FIG. 18, the interval D determined by the construction aid 78 is unambiguously between the inner rib 84 and the packing body 12, that is, between the outer surface of the foundation concrete Bc and the packing body 12. Secured.
Therefore, if the construction auxiliary tool 78 described above is used, it is possible to easily and simply lay a large number of packing main bodies 12 in parallel while securing the gap D on the upper surface of the foundation concrete Bc.

On the other hand, a mortar finish M is subsequently applied to the outer surface of the foundation concrete Bc as shown by a two-dot chain line in FIG. 18. At this time, a construction aid 78 is installed on the foundation concrete Bc. For example, the mortar of the mortar finish M is not accidentally applied to the upper surface of the foundation concrete Bc, and the mortar does not block the ventilation port 22 of the packing body 12.
Moreover, since the mortar of the mortar finish M is also filled in the groove 85 formed on the lower surface of the plate body 80, the mortar finish M is difficult to peel off from the foundation concrete Bc.
18 to 20, the plate main body 80 and the insertion piece 86 are integrally formed. However, the plate main body 80 and the insertion piece 86 are separated as shown in FIG. It may be.

  In this case, wings 88 projecting on both sides in the width direction of the insertion piece 86 are formed on the lower edge of the proximal end portion 86b of the insertion piece 86, and a hook 90 is formed. On the other hand, a ridge 92 extending in the longitudinal direction of the plate body 80 is integrally formed on the upper surface of the plate body 80, and a rail groove 94 with which the hook 90 can engage is formed on the ridge 92. Therefore, the insertion piece 86 can be attached to the plate body 80 at an arbitrary position as viewed in the longitudinal direction of the plate body 80.

As described above, in the case of the construction auxiliary tool 78 composed of the plate body 80 and the insertion piece 86 which are separate from each other, the construction auxiliary tool 78 is arranged at the corner of the upper surface of the foundation concrete Bc at the lower edge of the insertion piece 86 and It arrange | positions so that the back surface of the hook 90 may each address, and exhibits a function similarly to the above-mentioned integrated construction auxiliary tool.
In this case, if the insertion pieces 86 having different intervals D are prepared in advance, even if the required intervals D are different, it is easy to combine the insertion pieces 86 corresponding to the intervals D and the plate body 80. It becomes possible to cope with.
Finally, the foundation packing apparatus of the present invention is not limited to a wooden foundation, but can be similarly applied to a combination of a metal foundation and foundation concrete.
