The state which became longer than the state shown to 9 (a) is shown.

  Hereinafter, the building structure 100 in which the connecting member 20 according to an embodiment of the present invention is used will be described with reference to FIG.

  As shown in FIG. 1, the building structure 100 according to this embodiment includes a long foundation 1 (for example, a cloth foundation), a plurality of foundation packings 10, a wooden base 2, and a connecting member that connects the foundation packings 10. 20. In the present embodiment, as shown in FIG. 1, the right front side of the foundation 1 is outdoors, the left back side of the foundation 1 is indoors, and is also an underfloor space S. The plurality of foundation packings 10 extend along the longitudinal direction A (one direction) of the foundation 1 and are arranged on the foundation 1 in a state of being connected in series in the longitudinal direction A by the connecting member 20. Yes. The base 2 is arranged on these foundation packings 10 so as to sandwich the plurality of foundation packings 10 with the foundation 1 and is formed in a long shape in the longitudinal direction A.

  The foundation 1 is composed of a footing 1a and a rising portion 1b that stands upward from the footing 1a. The base 2 and the plurality of foundation packings 10 are fixed on the rising portion 1b by anchor bolts, square washers and nuts (both not shown) implanted in the foundation 1.

  Next, the basic packing 10 will be described below with reference to FIGS. The base packing 10 usually has a thickness in the vertical direction C of 10 to 30 mm. The width is 70 to 200 mm, and is determined according to the width of the base 2. The length in the longitudinal direction A is as long as about 500 to 2000 mm, and these are connected in series, and depending on the case, they are appropriately cut and used. The material is made of synthetic resin. In the present embodiment, a polypropylene resin containing a filler is used. However, the present invention is not particularly limited, and may be made of another synthetic resin.

  As shown in FIGS. 2 and 3, the side packings 10 a and 10 b along the longitudinal direction A of the base packing 10 have a large number for underfloor ventilation that passes through in the width direction B (direction perpendicular to the longitudinal direction A and the vertical direction C). The vent hole 12 is formed. Each vent hole 12 constitutes a recess that is recessed inward from both side surfaces 10 a, 10 b of the foundation packing 10. Since the foundation packing 10 receives a compressive load in the vertical direction C when in use, the foundation packing 10 is designed to ensure the necessary compressive strength when forming the air holes 12. The cross-sectional shape of the vent holes 12 in the present embodiment is a quadrangular shape, and is arranged in the longitudinal direction A so as to be adjacent to each other. Furthermore, each vent 12 has open portions 13a and 13b formed on either the upper or lower wall surface. The open portion 13a is formed by partially cutting the upper wall 15a, and the open portion 13b is formed by partially cutting the lower wall 15b. Each vent hole 12 has a three-sided enclosure shape with two side walls 14 adjacent to each other in the longitudinal direction A and either the upper wall 15a or the lower wall 15b, and the open portions 13a and 13b can be freely ventilated. is there. Thereby, a ventilation area increases, ventilation performance can be improved, and the contact surface of the foundation 1 and the base 2 which touches up and down can be dried. Further, as shown in FIG. 2, the open portions 13 a and 13 b are alternately formed in the vertical direction along the longitudinal direction A and the width direction B. Thereby, the fall of the bending strength of the foundation packing 10 accompanying formation of the open parts 13a and 13b can be suppressed.

  As shown in FIG. 5, the open portion 13b is formed to have a length in the width direction B longer than the open portion 13a formed in the upper wall 13a shown in FIG. Thereby, moisture etc. are easily dissipated from the upper surface of the foundation 1.

  As shown in FIG. 4, the base packing 10 is formed with a plurality of holes 16 penetrating in the vertical direction C for passing anchor bolts. A plurality of holes 16 are formed along the longitudinal direction A. Moreover, the convex part 17 and the recessed part 18 for positioning at the time of connecting the base packings 10 are formed in the both ends of the longitudinal direction A of the base packing 10, respectively, and the base packings 10 are connected in series and used. It is easy to do.

  Next, the base packing connecting member 20 for connecting the base packings 10 to each other will be described with reference to FIGS. 2, 6, and 7. As shown in FIG. 6, the connecting member 20 includes a substrate 21 and eight convex portions 22 a to 22 d and 23 a to 23 d that are formed to protrude from the one surface 21 a of the substrate 21 in the thickness direction (width direction B). The substrate 21 is a plate-like member that extends in the longitudinal direction A and has a rectangular planar shape. Among the eight convex portions 22a to 22d and 23a to 23d, the four convex portions 22a to 22d are arranged on one end side (left side in FIG. 6: one side) from the center in the longitudinal direction A of the substrate 21, Four convex portions 23 a to 23 d are arranged on the other end side (right side in FIG. 6: the other side) of the center of the substrate 21 in the longitudinal direction A. Further, the width dimension (width dimension in the vertical direction C) of the substrate 21 is preferably equal to or slightly smaller than the height (thickness) dimension of the base packing 10 (see FIG. 7).

  The connecting member 20 is formed symmetrically with respect to the center line D along the vertical direction C passing through the center in the longitudinal direction A of the substrate 21. That is, since the four convex portions 22a to 22d on one end side and the four convex portions 23a to 23d on the other end side have the same shape, the four convex portions 22a to 22d will be described. The description of ˜23d is omitted.

  Of the four convex portions 22a to 22d, the convex portion 22a and the convex portion 22b are arranged side by side in the vertical direction C, and are arranged closer to the center in the longitudinal direction A of the substrate 21 than the convex portions 22c and 22d. The convex portion 22a is disposed above the convex portion 22b. As shown in FIG. 2 and FIG. 7A, the convex portion 22a has a size that fits exactly into the open portion 13a. As shown in FIG. 6, the convex portion 22 a is formed so that the thickness in the vertical direction C is thicker than the convex portions 22 b and 22 c. The protrusion length from the one surface 21a of the convex part 22a and the convex part 22b is substantially the same length as shown in FIG.

  As shown in FIG. 6, the convex portion 22b (first convex portion) is arranged to be spaced downward from the convex portion 22a. As shown in FIG. 7A, the convex portion 22 b is configured to be insertable into the vent hole 12 opened at the upper portion by the opening portion 13 a of the basic packing 10. A locking claw 22b1 protruding downward is formed at the tip of the convex portion 22b. When the protrusion 22b is inserted into the vent hole 12 opened at the upper part by the opening part 13a, the locking claw 22b1 is formed on the lower wall 15b of the base packing 10 and notched by the opening part 13b. It can be locked. For this reason, the convex portion 22b is inserted by inserting the convex portion 22b into the vent hole 12. Specifically, the locking claw 22b1 is locked to the foundation packing 10 so that the connecting member 20 can be firmly fixed to the foundation packing 10, and the connecting member 20 is prevented from falling off the foundation packing 10. be able to.

  In addition, as shown in FIG. 6, the latching claw 23b1 is similarly formed in the convex part 23b (1st convex part) corresponding to the convex part 22b. For this reason, it becomes possible to fix the connection member 20 to the foundation packing 10 more firmly, and it is possible to prevent the connection member 20 from falling off the foundation packing 10. Further, since the thickness of the convex portion 22b in the vertical direction C is relatively thin, the locking claw 22b1 defines a part of the vent hole 12 in the process of inserting the convex portion 22b into the vent hole 12. It is easy to elastically deform upward when it comes into contact with.

  As shown in FIG. 6, the convex portion 22 c and the convex portion 22 d are arranged side by side in the vertical direction C, and are arranged on the outer side (one end side) in the longitudinal direction A of the substrate 21 than the convex portions 22 a and 22 b. . The convex portion 22c (second convex portion) is disposed above the convex portion 22d. As shown in FIG. 7B, the protruding length of the convex portion 22c and the convex portion 22d from the one surface 21a is substantially the same, but longer than the convex portions 22a and 22b. The convex portion 22 c is configured to be insertable into the vent hole 12 opened at the lower portion by the opening portion 13 b of the basic packing 10. A locking claw 22c1 protruding upward is formed at the tip of the convex portion 22c. In the present embodiment, as shown in FIG. 7B, the locking claw 22c1 is formed on the top of the basic packing 10 when the convex portion 22c is inserted into the lower vent hole 12 by the opening portion 13b. The wall 15a is disposed on the inner side in the width direction B (left side in FIG. 7) than the portion cut out by the opening 13a. Therefore, when the connecting member 20 is attached to the foundation packing having a width larger than the width of the foundation packing 10, the locking claw 22c1 is the upper wall 15a of the foundation packing and is notched by the opening portion 13a. It becomes possible to just lock the part. That is, the convex portion 22 c is configured to be insertable when inserted into the vent 12 of the basic packing having a width wider than that of the basic packing 10. Thereby, it becomes possible to correspond to the vent holes (recesses) 12 having different depths in the width direction B according to the size of the base packing, and the connecting member 20 can be firmly fixed to the large size base packing. It is possible to prevent the connecting member 20 from falling off the base packing. Since the size of the base packing in the width direction B increases, the locking claw 22b1 comes into contact with the front lower wall 15b portion that reaches the portion cut out by the opening 13b of the lower wall 15b. It is in the state which is not locked.

  Similarly, a locking claw 23c1 is formed on the protrusion 23c (second protrusion) corresponding to the protrusion 22c. For this reason, it becomes possible to fix the connection member 20 to the foundation packing with the large size of the width direction B more firmly, and it can prevent that the connection member 20 falls off from the foundation packing. Further, since the thickness of the convex portion 22c in the vertical direction C is relatively thin like the convex portion 22b, the locking claw 22c1 is one of the vent holes 12 in the process of inserting the convex portion 22c into the vent hole 12. When it comes into contact with the upper wall 15a defining the portion, it is easily elastically deformed downward.

  As shown in FIG. 6, the convex portion 22d is arranged to be spaced downward from the convex portion 22c. As shown in FIG. 7B, the convex portion 22d has a size that fits exactly into the open portion 13b. Similarly to the convex portion 22a, the convex portion 22d is formed so that the thickness in the vertical direction C is thicker than the convex portions 22b and 22c.

  As shown in FIG. 6, the substrate 21 has six through holes 24 a to 24 c and 25 a to 25 c that penetrate in the thickness direction (width direction B). Of the six through holes 24 a to 24 c and 25 a to 25 c, the through holes 24 a to 24 c are formed on one end side of the substrate 21, and the through holes 25 a to 25 c are formed on the other end side of the substrate 21. These through holes 24 a to 24 c and 25 a to 25 c are also arranged symmetrically with respect to the center line D. For this reason, three through-holes 24a-24c are demonstrated and description of the three through-holes 25a-25c is abbreviate | omitted.

  The three through holes 24a to 24c are arranged side by side along the longitudinal direction A, the through hole 24a is disposed at a position closest to the center of the substrate 21 in the longitudinal direction A, and the through hole 24b includes the convex portions 22a, It arrange | positions between 22b and the through-hole 24c is arrange | positioned between convex part 22c, 22d. All of these three through holes 24a to 24c are formed at positions facing the vent hole 12 in the width direction B when the two basic packings 10 are connected by the connecting member 20. For this reason, in the state which connected the two foundation packings 10 with the connection member 20, it becomes possible to suppress that the board | substrate 21 does not block | close the ventilation hole 12, and the ventilation performance of the foundation packing 10 falls.

  As shown in FIG. 2, the connecting member 20 includes two protrusions 22 b and 22 c out of the four protrusions 22 a to 22 d on one end side, which are close to the end in the longitudinal direction A of the base packing 10 </ b> A. It is inserted into the vent hole 12 from the side surface 10a side (indoor side), and in this embodiment, the convex portion 22b is engaged with and attached to the basic packing 10A. Further, the connecting member 20 has the convex portions 23b and 23c among the four convex portions 23a to 23d on the other end side, on the side surface 10a side with the two vent holes 12 close to the end portion in the longitudinal direction A of the base packing 10B. It is inserted from the (indoor side), and in this embodiment, the convex portion 23b is engaged with and inserted into the foundation packing 10B. The foundation packing 10A is the foundation packing 10 arranged on the left side in FIG. 2, and the foundation packing 10B is the foundation packing 10 arranged on the right side in FIG.

  Thus, the two foundation packings 10 (the foundation packing 10A and the foundation packing 10B) arranged between the foundation 1 and the base 2 are connected in series in the longitudinal direction A by the connecting member 20. At this time, since the convex portions 22a, 22d, 23a, and 23d are fitted into the open portions 13a and 13b, the two basic packings 10 that are connected are not easily displaced in the longitudinal direction A.

  As described above, according to the connecting member 20 of the present embodiment, the convex portions 22b and 23b of the connecting member 20 are formed in the vent holes (recessed portions) 12 of the two base packings 10 arranged adjacent to each other on the base 1. It is possible to connect the two foundation packings 10 in series in the longitudinal direction A by inserting them from the side surface 10a side of the foundation packing 10 and attaching them. For this reason, it is possible to connect the base packings 10 without causing the connecting member 20 to interfere with the base 2 and the adjustment plate (not shown). Further, since the connecting member 20 is inserted from the side surface 10 a side of the foundation packing 10, the base 2 is placed on the foundation packing 10 before the foundation 2 is arranged on the foundation packing 10, and after the foundation 2 is arranged on the foundation packing 10. It is possible to connect the foundation packings 10 with the connecting member 20 in various situations such as a state where the foundation packings 10 are arranged (for example, the foundation packing 10 of an existing building). That is, the connecting member 20 can connect the base packings 10 in the longitudinal direction A even after retrofitting. Furthermore, by connecting the foundation packings 10 from the side surface 10a side, it is possible to effectively prevent the ends of the foundation packing 10 from being displaced in the horizontal direction due to the vibration of the earthquake, and to improve the earthquake resistance of the building. . Moreover, also in the building structure 100 in which the connecting member 20 is adopted, the same effect as described above can be obtained, and the foundation packings 10 are connected to each other without causing the connecting member 20 to interfere with the base 2 and the adjustment plate (not shown). Even if the base 2 is disposed on the foundation packing 10 (for example, the foundation packing 10 of an existing building), the building structure 100 in which the foundation packings 10 are connected by the connecting member 20 can be obtained. . Furthermore, it is possible to effectively prevent the ends of the foundation packing from being displaced in the horizontal direction due to the earthquake vibration, and to obtain a building structure with improved earthquake resistance.

  Although not shown, when a known draining material is not provided on the foundation or the like, the protrusions 22b and 23b of the connecting member 20 are connected to the vent holes (recesses) 12 of the two foundation packings 10 in the foundation packing. 10 may be inserted from the side surface 10b side (outdoor side). Also in this case, the same effect as described above can be obtained.

  In addition, the foundation packing 10 is formed with a plurality of ventilation holes 12 that form recesses, and the projections 22b and 23b can be inserted into the ventilation holes 12, so that a foundation for underfloor ventilation is provided. It is possible to connect the packings 10 in the longitudinal direction A.

  Then, the 1st modification of a connection member is demonstrated below, referring FIG. In addition, about the thing similar to the above-mentioned embodiment, it attaches | subjects a same sign and abbreviate | omits description. The connecting member 220 in the first modification is formed such that the length in the longitudinal direction A is longer than that of the connecting member 20 of the above-described embodiment. More specifically, the base plate 221 of the connecting member 220 has the same length as the entire length of the two base packings 10 arranged and connected on the base 1. Further, the through holes 24 a to 24 c and 25 a to 25 c described above are not formed in the substrate 221 of the connecting member 220. That is, the substrate 221 is configured to be able to block all the air holes 12 formed in the side surface 10a of the foundation packing 10 in a state where the two foundation packings 10 are connected by the connecting member 220. Further, the connecting member 220 has a larger number of convex portions 22a to 22d and 23a to 23d than the case of the above-described embodiment because the substrate 221 is elongated in the longitudinal direction A. For this reason, the connecting member 220 becomes more difficult to drop off from the basic packing 10.

  In the building structure in which the connecting member 220 according to this modification is employed in the above-described building structure, the connecting member 220 blocks all the vent holes 12 on the side surface 10a side of the foundation packing 10 with the substrate 221. Even if the foundation packing 10 for ventilation is used, the building structure can be an airtight type. In addition, also when the above-mentioned through-holes 24a-24c and 25a-25c are not formed in the board | substrate 21 of the connection member 20 in the above-mentioned embodiment, the two basic packings 10 connected using two or more said connection members 20 are used. All the air holes 12 on the side surface 10a side may be closed. Even in this case, the same effect as described above can be obtained.

  Then, the 2nd modification of a connection member is demonstrated below, referring FIG. The connecting member 320 in the second modified example is configured in such a manner that the length in the longitudinal direction A of the substrate 321 can be changed, and the other configuration is substantially the same as that of the connecting member 20 in the above-described embodiment. In addition, about the thing similar to the above-mentioned embodiment, it attaches | subjects a same sign and abbreviate | omits description.

  The substrate 321 has two divided bodies 322 and 323 which are divided so as to be slidable in the longitudinal direction A. The divided body 323 includes a divided main body 323a in which four convex portions 23a to 23d (only convex portions 23b and 23d are shown in FIG. 9) and through holes 25b and 25c are formed, and a slide half whose thickness is half that of the divided main body 323a. Part 323b. A plurality of holes 323c penetrating in the thickness direction (width direction B) are formed along the longitudinal direction A in the slide half 323b. The plurality of holes 323 c are arranged at equal intervals along the longitudinal direction A.

  The divided body 322 includes a divided main body 322a in which convex portions 22b and 22d and through holes 24b and 24c are formed, and a slide half 322b whose thickness is half that of the divided main body 322a. A plurality of protrusions 322 c protruding in the thickness direction (width direction B) are formed along the longitudinal direction A on the slide half 322 b. The plurality of protrusions 322c are arranged at equal intervals along the longitudinal direction A, and are configured to be fitted into the holes 323c.

  The slide half 322b of the split main body 322 and the slide half 323b of the split main body 323 constitute a change mechanism 325 that can change the length of the substrate 321 in the longitudinal direction A. That is, the divided bodies 322 and 323 are moved away from each other along the longitudinal direction A, and the slide halves 322b and 323b are changed from the position shown in FIG. 9A to the position shown in FIG. 9B. By fitting the protrusion 322c into the hole 323c, the length of the connecting member 320 in the longitudinal direction A can be changed. That is, the separation distance in the longitudinal direction A between the convex portions 22b and 22d of the connecting member 320 and the convex portions 23b and 23d can be changed.

  In such a connecting member 320, the ventilation hole 12 formed in the side surface 10a of one foundation packing 10A of the two adjacent foundation packings 10 and the ventilation hole 12 formed in the side surface 10a of the other foundation packing 10B. It is possible to change the separation distance of the convex portions 22b, 22c, 23b, and 23c formed on one side and the other side of the connecting member 320 according to the separation distance. For this reason, it becomes possible to connect corresponding to the various foundation packing arrange | positioned adjacently on the foundation 1. FIG.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims. For example, the connecting member 20 in the above-described embodiment has the protrusions 22b, 22c, 23b, and 23c having different protrusion lengths, but the two protrusions 22b and 23b or the protrusions 22c having the same protrusion length are formed. , 23c may be formed. In addition, the number of convex parts should just be insertable in one or more recessed parts (vent hole 12) of each foundation packing connected, and should just be two or more.

  Moreover, the convex parts 22b and 23b of the connecting member 20 may be configured to be insertable into a concave part formed on one side surface of the basic packing. In short, the protrusions 22b and 23b are not limited to be inserted into the vent hole 12, and may be configured to be insertable into a recess formed on one side of the airtight basic packing. .

  Further, the projections 22b and 23b are not particularly required to have the locking claws 22b1 and 23b1 as long as they can be inserted into the recesses of the basic packing, and may have any shape. . That is, the shape which can just be fitted in a recessed part may be sufficient. If it carries out like this, it will become possible to insert a connection member in a foundation packing by fitting a convex part to a crevice. Further, the opening shape of the recess may be any shape such as a triangle, a quadrangle, a polygon, and a circle, and the protrusion may be configured to be insertable by being inserted into the recess.

  Further, the locking claws 22b1 and 23b1 may be formed not at the tips of the convex portions 22b and 23b but at midway portions. In short, it is only necessary that the base packing 10 can be locked. In this case, the step part which the said latching claw latches in the recessed part should just be formed.
