Description

  The present invention relates to a foundation spacer interposed between a foundation of a building and a foundation placed on the foundation.

  Conventionally, in order to ventilate the underfloor of a building, a base spacer, in which an air passage for underfloor ventilation is previously formed, is interposed between the foundation and the base, so that the underfloor ventilation is provided between the foundation and the base. It is known to secure a ventilation path.

  For example, Patent Document 1 discloses a base spacer as described above in which a plurality of air passages that allow air to flow across the base spacer in the width direction are formed. This air passage is constituted by a through-hole penetrating in the width direction provided side by side in the longitudinal direction of the base spacer, or by a groove extending in the width direction formed at equal intervals on the lower surface of the base spacer. .

  In addition, when an anchor bolt for fixing the base is projected on the foundation on which the base spacer is placed, a through hole through which the anchor bolt can be inserted is provided to avoid the anchor bolt. A base spacer provided in advance is also known.

  For example, in Patent Document 2, a plurality of substantially rectangular through holes extending in the longitudinal direction of the base spacer and extending in the longitudinal direction so as to span a plurality of the air passages are provided in the longitudinal direction, and anchor bolts are inserted into the through holes. Possible foundation spacers are disclosed.

According to the base spacer, not only can the position of the anchor bolt be accommodated by the through hole, but also the material cost for the volume of the through hole can be reduced.

  However, in the foundation spacer provided with the air passage and the through-hole, the cross-sectional area of the cross-section of the base spacer is reduced by the amount of the air passage and the through-hole. Therefore, it is difficult to sufficiently secure the strength against the compressive load in the direction of action of the load (that is, the vertical direction).

  Moreover, since the relative position of the anchor bolt and the base spacer is not necessarily determined, the through hole is extended in the longitudinal direction of the foundation in order to be able to install the base spacer while avoiding the anchor bolt regardless of the relative position. It is necessary to provide a plurality of through-holes in one spacer so that anchor bolts can be selectively inserted into any of the through-holes, thus increasing the occupied area of the through-holes. The spacer as a whole becomes increasingly disadvantageous in strength.

  In particular, in the portion located immediately below the pillar of the building, the compressive load applied to the base spacer is large, and high strength is required to cope with this.

  In order to ensure such strength, it is necessary to reduce the area of the ventilation path in the base spacer and increase the thickness thereof, and the ventilation performance is reduced accordingly.

  In view of such circumstances, in the present invention, in the base spacer provided with the air passage, a through hole or a plurality of through holes extending in the longitudinal direction of the base is provided so as to flexibly correspond to the position of the anchor bolt. However, it is an object of the present invention to provide a foundation spacer that can secure sufficient strength without reducing the air passage area and a foundation structure using the foundation spacer.

  The invention according to claim 1 is a foundation spacer interposed between a foundation of a building and a foundation placed on the foundation, and a lower surface that can be placed on the upper surface of the foundation and the foundation placed thereon A spacer body having a top surface that extends along the longitudinal direction of the foundation and a reinforcing member thereof.

It is characterized by having a road.

  Here, “the reinforcing member has an upper surface located on the substantially same plane as the upper surface of the spacer body in the fitted state” means that both upper surfaces are located on the same plane or Both upper surfaces are close enough that the load acting on the entire spacer can be distributed to both upper surfaces.

  According to a second aspect of the present invention, in the foundation spacer according to the first aspect, the reinforcing member is substantially the same as the through hole so that the reinforcing member closes substantially the entire through hole when fitted into the through hole. It is characterized by being formed in the same shape.

  The invention according to claim 3 is a foundation spacer interposed between a foundation of a building and a foundation placed on the foundation, and a lower surface that can be placed on the upper surface of the foundation and the foundation placed thereon A spacer body having a top surface that extends along the longitudinal direction of the foundation and a reinforcing member thereof. The spacer body can be ventilated across the spacer body in a width direction perpendicular to the longitudinal direction. A plurality of air passages are provided at predetermined intervals in the longitudinal direction of the spacer main body, anchor bolts protruding on the foundation can be inserted, and the air passages of the spacer main body are connected to the spacer main body. A through hole is provided in the longitudinal direction of the main body, extending in the longitudinal direction and penetrating the spacer body in the vertical direction, and the reinforcing member is arranged in the longitudinal direction of the spacer body. The spacer body is shorter than the through hole of the spacer body, can be fitted into the through hole, and has an upper surface located in the same plane as the upper surface of the spacer body in the fitted state, and in the fitted state. It has an auxiliary air passage connected to the air passage facing the through hole, and can be selectively attached to a plurality of positions where the auxiliary air passage and the air passage facing the through hole are connected, and this reinforcing member is attached Thus, the anchor bolt can be inserted into a part of the through hole remaining without being blocked by the reinforcing member.

  According to a fourth aspect of the present invention, in the foundation spacer according to the third aspect, irregularities that can be fitted to each other are formed on the peripheral edge portion of the through hole and the outer peripheral edge portion of the reinforcing member in the spacer body. In addition, the reinforcing member is configured to be mounted at a position where the auxiliary air passage of the reinforcing member and the air passage facing the through hole of the spacer main body are connected by fitting the irregularities. It is what.

  The invention according to claim 5 is the foundation spacer according to claim 3 or 4, wherein the through holes of the spacer body are provided at a plurality of positions aligned in the longitudinal direction of the spacer body, and the reinforcing member is used as the reinforcing member. A part of the through hole that is shorter than the through hole of the spacer body in the longitudinal direction of the spacer body and remains without being blocked by the reinforcing member when the reinforcing member is mounted in the through hole of the spacer body. In addition to what the anchor bolt can be inserted into, it is provided with what is formed in substantially the same shape as the through hole so as to close substantially the entire through hole when fitted into the through hole. It is a feature.

  In the invention according to claim 6, the foundation spacer according to any one of claims 1 to 5 is interposed between the foundation of the building and the foundation placed thereon, and for the foundation. The reinforcing member is fitted only into the through hole of the spacer main body in the spacer that is located under the pillar standing on the base, and at least a portion of the through hole that directly contacts the pillar is formed by the reinforcing member. It is a foundation structure characterized by being blocked.

  The invention according to claim 7 is the foundation structure according to claim 6, wherein the through hole of the spacer main body is located so as to straddle the region directly below the column and the region outside the column, The reinforcing member is partially fitted only in the region immediately below.

  According to the first aspect of the present invention, the spacer main body extending along the longitudinal direction of the foundation is provided with a plurality of through holes into which the anchor bolts can be inserted side by side in the longitudinal direction of the spacer main body. By passing the anchor bolt through the through hole, the spacer body can be installed while flexibly corresponding to the position of the anchor bolt. In addition, by inserting a reinforcing member into a through hole that does not allow anchor bolts to pass through, that is, a through hole that is unnecessary as a result, and receiving a load on both the reinforcing member and the spacer main body, The burden on strength can be reduced. Therefore, the strength of the base spacer can be improved while maintaining good workability when the spacer body is installed by the plurality of through holes.

  Further, since the reinforcing member is provided with an auxiliary air passage connected to the air passage that faces the through hole of the spacer body in the fitted state, the air passage is blocked even if the reinforcing member is fitted into the through hole. There is nothing. Therefore, the strength of the base spacer can be improved while ensuring good ventilation performance.

  The through-hole into which the reinforcing member is fitted can be appropriately selected according to the specification. For example, a through-hole located in a portion where a particularly large load is applied, such as a through-hole located under a pillar standing on a base. The reinforcing member may be fitted only in the hole, or may be fitted in all through holes that do not pass the anchor bolt.

  According to the invention of claim 2, the reinforcing member is formed in substantially the same shape as the through hole so as to close substantially the entire through hole when fitted into the through hole. The spacer strength can be restored over substantially the entire area of the through hole.

  According to the invention of claim 3, since the through-hole through which the anchor bolt provided in the spacer body can be inserted extends in the longitudinal direction of the spacer body, it can flexibly cope with variations in the position of the anchor bolt. be able to. Then, by attaching a reinforcing member to a portion of the through hole that is detached from the anchor bolt, that is, a surplus portion so that the reinforcing member can receive a load, the load on the strength of the spacer body can be reduced. Therefore, the strength of the base spacer can be improved while maintaining workability when the spacer main body is installed by the through hole extending in the longitudinal direction of the base spacer.

  Further, since the reinforcing member can be selectively mounted at a plurality of positions where the auxiliary air passage and the air passage facing the through hole are connected, the reinforcing member is placed at any of these positions. Even if it is attached, the air passage is not blocked, and the strength of the base spacer can be improved while ensuring good air permeability. Furthermore, the position where the anchor bolt is passed can be changed by changing the position where the reinforcing member is mounted according to the relative position between the anchor bolt and the spacer body.

  According to the invention which concerns on Claim 4, the unevenness | corrugation which can be mutually fitted is formed in the peripheral part of the said through-hole, and the outer peripheral part of the said reinforcement member, The said reinforcement is carried out by making this unevenness fit. Since the reinforcing member is mounted at a position where the auxiliary air passage of the member and the air passage facing the through hole of the spacer main body are connected, the position of the auxiliary air passage of the reinforcing member and the through hole of the spacer main body Therefore, the positioning can be performed by a simple operation of fitting the concaves and convexes without requiring a troublesome positioning operation such as performing alignment while visually confirming the position of the air passage that faces the surface. Therefore, the workability at the time of mounting the reinforcing member can be improved. Moreover, after mounting | wearing with a reinforcement member, the mutual displacement of a reinforcement member and a spacer main body can also be prevented by fitting of the said unevenness | corrugations.

  According to the fifth aspect of the present invention, it is possible to select an appropriate through hole for passing the anchor bolt from the plurality of through holes, and the through hole extends in the longitudinal direction of the spacer body. Therefore, the position of the anchor bolt can be dealt with more flexibly. Moreover, it is possible to reinforce any through hole by fitting a long reinforcing member into a through hole that is not used and fitting a short reinforcing member into a portion of the through hole that is used where no anchor bolt is present.

  As in the invention according to claim 6, the reinforcing member is fitted only into the through hole located under the column where a large load is applied, and at least a portion of the through hole that is directly below the column is blocked by the reinforcing member. As a result, material costs can be saved while securing sufficient strength in the portion directly below the column where the load is severe.

  In particular, as in the invention according to claim 7, when the through hole is located so as to straddle the region directly below the column and the region outside the column, the reinforcing member is partially provided only in the region immediately below the column. By fitting, the material cost can be further reduced.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the base spacer 10 </ b> A is interposed between the foundation 40 of the building and the base 50 placed thereon. The base spacer 10A includes a spacer main body 20A extending along the longitudinal direction of the foundation 40 and a reinforcing member 30A.

  The spacer body 20A is formed in a substantially long plate shape with synthetic resin or the like, and has a lower surface that can be placed on the upper surface of the foundation 40 and an upper surface 20a on which the foundation 50 can be placed. Further, the spacer body 20A is provided with a plurality of air passages 22 for ventilating the floor under the building and a plurality of through holes 24 for inserting anchor bolts 45 protruding from the foundation 40. It has been.

  The air passage 22 extends in the width direction perpendicular to the longitudinal direction of the spacer body 20A, and a plurality of the air passages 22 are provided at predetermined intervals in the longitudinal direction of the spacer body 20A.

  The through hole 24 extends in the longitudinal direction of the plurality of air passages 22 of the spacer body 20A across the longitudinal direction of the spacer body 20A and penetrates the spacer body 20A in the vertical direction. A plurality of 20A are provided side by side in the longitudinal direction.

  Specifically, as shown in FIG. 3, the spacer main body 20A includes a plurality of partition walls 26 arranged side by side at a predetermined interval in the longitudinal direction of the spacer main body 20A, and upper end portions of the partition walls 26. It has a top plate 28 that connects them in the arrangement direction.

  Each partition wall portion 26 extends in the width direction of the spacer body 20A, and an air passage 22 that opens on both sides in the width direction of the spacer body 20A is formed between the partition wall portions 26. Therefore, the spacer body 20 </ b> A can be ventilated across the width direction of the spacer body 20 </ b> A through the air passages 22.

  The bottom surfaces of the partition walls 26 are located on substantially the same plane, and these bottom surfaces constitute the lower surface of the spacer main body 20A that can be placed on the upper surface of the foundation 20 described above. Further, the upper end portion of each partition wall portion 26 is connected to the lower surface of the top plate 28 so as to hang down from the lower surface.

  The top plate 28 has a long plate shape extending in the longitudinal direction of the spacer body 20A. The top surface of the top plate 28 is a plane substantially parallel to the plane formed by the bottom surface of the partition wall portion 26, and this top surface constitutes the top surface 20a of the spacer body 20A on which the base 50 described above can be placed. Yes.

  The through hole 24 for inserting the anchor bolt is composed of a portion that penetrates the top plate 28 and a portion that divides the partition wall portion 26.

  The portion of the through hole 24 that penetrates the top plate 28 is formed of a through hole 28a that penetrates the top plate 28 in the thickness direction. The through hole 28a has a size that allows the anchor bolt 45 to be inserted, has a rectangular shape that extends in the longitudinal direction of the spacer body 20A so as to straddle the plurality of partition walls 26, and extends in the longitudinal direction of the spacer body 20A. It is formed at a plurality of positions.

  In the portion where the partition wall portion 26 of the through hole 24 is divided, the width direction of the spacer body 20A is such that the partition wall portion 26 is hollowed out at substantially the same size as the width direction of the spacer body 20A in the through hole 28a. It is divided into two.

  Further, in the through hole 24, the air passage 22 is opened in the longitudinal direction of the spacer main body 20 </ b> A by the divided partition wall portion 26, and communicates with the adjacent air passage 22.

  On the other hand, the reinforcing member 30A is formed in a shape that can be fitted into the through hole 24 of the spacer body 20A with synthetic resin or the like, like the spacer body 20A. In the present embodiment, as shown in FIGS. 1 and 2, when the reinforcing member 30A is fitted into the through-hole 24, the through-hole 24 can be closed substantially entirely. It is formed in substantially the same shape as the hole 24.

  In addition, the reinforcing member 30A is connected to the upper surface 30a positioned substantially on the same plane as the upper surface 20a of the spacer body 20A in the fitted state, and the air passage 22 facing the through hole 24 of the spacer body 20A in the fitted state. And an auxiliary air passage 32.

  Specifically, as shown in FIG. 4, the reinforcing member 30 </ b> A includes a plurality of auxiliary partition walls 34 arranged side by side in the longitudinal direction of the spacer body 20 </ b> A at substantially equal intervals to the partition walls 26 of the spacer body 20 </ b> A. And an auxiliary top plate 36 that can be fitted into a through hole 28a formed in the top plate 28 of the spacer body 20A.

  The auxiliary top plate 36 has a rectangular shape substantially the same as the through hole 28a of the top plate 28 of the spacer body 20A, and the auxiliary top plate 36 is fitted into the through hole 28a of the top plate 28. The through hole 28a is closed.

  The distance between the bottom surface of each auxiliary partition wall 34 and the upper surface of the auxiliary top plate 36 is set to be substantially the same as the distance between the lower surface of the spacer main body 20A and the upper surface 20a. In a state where the member 30A is fitted in the through hole 24 of the spacer body 20A, the upper surface of the auxiliary top plate 36 and the upper surface 20a of the spacer body 20A are positioned on substantially the same plane. The upper surface of the auxiliary top plate 36 constitutes the upper surface 30a of the reinforcing member 30A described above. The auxiliary partition wall 34 is connected to the lower surface of the auxiliary top plate 36.

  Note that the upper surface 30a of the reinforcing member 30A and the upper surface 30a of the spacer body 20A do not have to be located on the same plane, and are close enough to disperse the load from the base 50 placed thereon. Just do it.

  Each auxiliary partition wall 34 extends in the width direction of the spacer main body 20A, and the above-described auxiliary air passage 32 is configured by a space sandwiched between the auxiliary partition walls 34 and opened on both sides in the width direction of the spacer main body 20A. Has been.

  In addition, each auxiliary partition wall 34 is separated from each partition wall portion 26 of the above-described spacer body 20A facing the through hole 24 when the reinforcing member 30A is fitted into the through hole 24 of the spacer body 20A. It is arranged at the matching position. Therefore, the auxiliary ventilation path 32 matches the ventilation path 22 facing the through hole 24 of the spacer body 20A in the fitted state, and crosses the spacer body 20A in the width direction through the auxiliary ventilation path 32 and the ventilation path 22. Can be inserted.

  Next, the installation procedure and operation of the base spacer 10A configured as described above will be described with reference to FIGS.

  First, the spacer body 20 </ b> A is placed on the upper surface of the foundation 40. At this time, the anchor bolt 45 protruding from the foundation 40 is passed through an appropriate through hole 24 among the plurality of through holes 24 of the spacer body 20A.

  Since the plurality of through holes 24 are provided and extend in the longitudinal direction of the spacer main body 20A, the spacer main body 20A can be installed while flexibly responding to the position of the anchor bolt 45 and its variation. .

  Next, the reinforcing member 30 </ b> A is fitted into the through hole 24 other than the through hole 24 through which the anchor bolt 45 is passed. The through hole 24 into which the reinforcing member 30A is fitted can be selected as appropriate. However, in the present embodiment, the through hole 24 located under the column 52 standing on the base 50 that is a portion to which a particularly large load is applied. Only the reinforcing member 30A is fitted.

  Then, the base 40 is placed on the upper surface 20a of the spacer body 20A.

  Since the reinforcing member 30A has an upper surface 30a located on the substantially same plane as the upper surface 20a of the spacer body 20A in the fitted state, the load from the base 50 is distributed to the reinforcing member 30A and the spacer body 20A. The

  In this way, by receiving the load on both the reinforcing member 30A and the spacer main body 20A, the load on the strength of the spacer main body 20A can be reduced. Even if the through-hole 24 for anchor bolt insertion is located, the load can be sufficiently tolerated. Therefore, the strength of the base spacer 10A can be improved while maintaining good workability when the spacer body 20A is installed by the plurality of through holes 24 extending in the longitudinal direction of the spacer body 20A.

  In the present embodiment, since the reinforcing member 30A is fitted only in the through hole 24 located below the column 52, the material cost can be saved while ensuring sufficient strength in the portion directly under the column 52 where the load is severe. Can do. Further, by limiting the positions where the reinforcing members 30A are fitted in this way, the work for reinforcement on site can be reduced as much as possible.

  Further, as described above, the auxiliary air passage 32 of the reinforcing member 30A is configured to match the air passage 22 facing the through hole 24 of the spacer main body 20A in the fitted state as described above. Even if fitted into the through-hole 24, the air passage 22 is not blocked, and the strength of the base spacer 10A can be improved while ensuring good air permeability.

  Further, since the reinforcing member 30A is formed in substantially the same shape as the through hole 24 so as to close substantially the entire through hole 24 when fitted into the through hole 24, the through hole 24 The spacer strength can be restored over substantially the entire area.

  In the above-described embodiment, the reinforcing member 30 </ b> A is fitted into the through hole 24 positioned below the column 52. However, the reinforcing member 30 </ b> A may be fitted into all the through holes 24 that do not pass the anchor bolt 45.

  Further, in the illustrated example, the auxiliary partition walls 34 positioned at both ends in the arrangement direction of the auxiliary top plates 36 of the reinforcing member 30A are disposed above the air passages 22 positioned at both ends in the longitudinal direction of the spacer body 20A in the through hole 24. Although the form which covers and protrudes from the side surface is shown, the auxiliary top plate 36 of the reinforcing member 30A is cut at the side surfaces of the auxiliary partition wall portions 34 located at both ends in the arrangement direction as shown in FIG. The plate 28 may be protruded from the side surface of the partition wall portion 26 located at both ends of the through hole 24.

  Furthermore, in the above-described embodiment, the reinforcing member 30A has a plurality of auxiliary partition walls 34 arranged in the longitudinal direction of the spacer body 20A at substantially equal intervals to the respective partition walls 26 of the spacer body 20A. Although the auxiliary air passage 32 formed by being sandwiched between the portions 34 is shown to match the air passage 22 facing the through hole 24 of the spacer body 20A one by one, it is not always necessary to have such a form.

  For example, when reinforcing a portion of the spacer body 20A to which a relatively small load is applied, the interval between the auxiliary partition walls 34 of the reinforcing member 30A is twice or more than the interval between the partition walls 26 of the spacer body 20A. As an integral multiple, the auxiliary ventilation path 32 of the reinforcing member 30A may be connected to a plurality of ventilation paths 22 facing the through hole 24 of the spacer body 20A.

  Further, the shape of the through hole 28a formed in the top plate 28 of the spacer body 20A is not necessarily rectangular, and both ends in the longitudinal direction may be arcuate. Or it does not necessarily extend in the longitudinal direction of the spacer main body 20A, and may be square or circular. Thus, even if the through hole 28a does not extend in the longitudinal direction of the spacer body 20A, if a plurality of the through holes 28a are provided in the longitudinal direction, the position of the anchor bolt 45 can be flexibly supported.

  On the other hand, when the through hole 24 of the spacer body 20A is formed in a shape extending in the longitudinal direction of the spacer body 20A as in the above embodiment, the spacer body 20A is used as a reinforcing member as shown in FIG. It is also possible to employ a reinforcing member 30B in which the dimension in the longitudinal direction is shorter than the dimension in the longitudinal direction of the through hole 24 of the spacer body 20A.

  The length of the reinforcing member 30B is such that the reinforcing member 30B is mounted at a position where the auxiliary air passage 34 of the reinforcing member 30B and the air passage 22 facing the through hole 24 in the through hole 24 of the spacer body 20A match. In this state, the anchor bolt 45 is set to be able to be inserted into a part of the through hole 24 remaining without being blocked by the reinforcing member 30B.

  This reinforcing member 30B has a shorter dimension in the longitudinal direction of the spacer main body 20A than a reinforcing member 30A (hereinafter referred to as a closing type reinforcing member 30A) capable of closing the substantially entire through-hole 24 described above. Specifically, it has a rectangular auxiliary top plate 36 ′ shorter in length than the auxiliary top plate 36 of the closing type reinforcing member 30 </ b> A, and has the same auxiliary partition wall 34 as described above. have.

  The number of the auxiliary partition walls 34 is shorter than the number of the auxiliary partition walls 34 of the closing reinforcing member 30A, that is, the number of the partition walls 26 facing the through holes 24 of the spacer body 20A. The number of auxiliary ventilation paths 32 formed by being sandwiched between the auxiliary partition walls 34 is also smaller than the number of ventilation paths 22 facing the through holes 24 of the spacer body 20A.

  Since the auxiliary top plate 36 'has a rectangular shape shorter than the length of the through hole 28a of the top plate 28 of the spacer main body 20A into which the auxiliary top plate 36' is fitted, the reinforcing member 30B is disposed in the through hole 28a. Thus, the spacer main body 20A can be moved in the longitudinal direction, and can be mounted at a plurality of positions where the auxiliary air passage 32 and the air passage 22 facing the through hole 24 coincide.

  If the reinforcing member 30B configured as described above is used, the reinforcing member 30B is attached to a portion of the through hole 24 through which the anchor bolt 45 passes in the spacer main body 20A, that is, a portion that is disengaged from the anchor bolt, that is, a surplus portion. By receiving the load, the through-hole 24 through the anchor bolt 45 is secured while ensuring the advantage that the through-hole 24 extending in the longitudinal direction of the spacer body 20A can flexibly cope with variations in the position of the anchor bolt 45. Can also be reinforced.

  Further, since the reinforcing member 30B can be mounted at a plurality of positions where the auxiliary air passage 32 and the air passage 22 facing the through hole 24 are matched, the reinforcement member 30B can be attached to any of these positions. Even if the member 30B is mounted, the air passage 22 is not blocked, and the strength of the base spacer 10A can be improved while ensuring good air permeability.

  Furthermore, the position where the anchor bolt 45 is passed can be changed by changing the position where the reinforcing member 30B is mounted depending on the relative position between the anchor bolt 45 and the spacer body 20A.

  In the reinforcing member 30B, as in the above-described modified example of the closed type reinforcing member 30A, the interval between the auxiliary partition walls 34 forming the auxiliary air passage 32 is set to 2 as the interval between the partition walls 26 of the spacer body 20A. The auxiliary air passage 32 of the reinforcing member 30A may be connected to a plurality of air passages 22 facing the through holes 24 of the spacer main body 20A as a double or an integer multiple thereof.

  Further, if this reinforcing member 30B and the above-described closed type reinforcing member 30A are used in combination, the remaining portions of the plurality of through holes 24 extending in the longitudinal direction of the spacer body 20A are left except for the position where the anchor bolt 45 is passed. All can be closed, and the spacer strength can be effectively restored over the entire length of the base spacer 10A.

  Alternatively, when the through hole 24 is located under the pillar 52 as in the above embodiment and only a part of the through hole 24 is located directly under the pillar 52, the reinforcing member is provided only in the through hole 24. 30B may be fitted to close a portion of the through hole 24 that is directly below the pillar. At that time, if the reinforcing member 30B having a length substantially coincident with a part of the through hole 24 is used so that the reinforcing member 30B is partially fitted only in the region immediately below the column, the column with severe load While securing sufficient strength in the portion immediately below 52, material costs can be reduced and cost reduction can be achieved compared to closing substantially the entire through-hole 24.

  The reinforcing member 30B may be manufactured in a plurality of lengths, but the closed reinforcing member 30A is cut to a desired length according to the position of the anchor bolt 45. You may make it obtain.

  Further, as shown in FIG. 7, a slit 36a is provided in a portion of the auxiliary top plate 36 of the closed type reinforcing member 30A located between the partition walls 26, and the auxiliary ceiling plate is formed at a desired position along the slit 36a. The plate 36 can also be divided.

  By providing the slit 36a in this way, it is not necessary to manufacture the reinforcing members 30B having various lengths, and the same shape can be mass-produced, and can be divided and used depending on the case. it can.

  In the above embodiment, the plurality of through holes 24 of the spacer main body 20A are provided. However, when the position of the anchor bolt 45 is known in advance, the through hole 24 extending in the longitudinal direction of the spacer main body 20A. One reinforcing member 30B may be fitted into the through hole 24.

For this purpose, it is only necessary to form irregularities that can be fitted to each other on the outer peripheral edge of the reinforcing member 30 </ b> B and the peripheral edge of the through hole 24.

  FIG. 8 shows the base spacer 10B in the form in which the irregularities are formed.

  In the spacer main body 20B in the base spacer 10B, the width in the width direction of the spacer main body 20B in the top plate 28 is smaller than that in the spacer main body 20A described above, and the spacers in the through holes 28a formed in the top plate 28 The dimension of the main body 20B in the width direction is large.

  Therefore, the end of each partition wall portion 26 on the outer side in the width direction of the spacer body 20B protrudes to the outside of the top plate 28, and the inside of each partitioned partition wall portion 26 in the region where the through hole 28a is provided. This end protrudes from the peripheral edge of the through hole 28a into the through hole 28a.

  In addition, the upper surface of each partition wall portion 26 is positioned on substantially the same plane as the upper surface of the top plate 28, and constitutes the upper surface 20a of the spacer body 20B together with the top plate 28. For this reason, the unevenness | corrugation 28b which repeats protrusion in the said through-hole 28a is formed in the peripheral part of the width direction of the spacer main body 20B in the said through-hole 28a.

  On the other hand, as the reinforcing member for the base spacer 10B, a closed reinforcing member 30C and a reinforcing member 30D having a shorter length are provided.

  On the outer peripheral edge of the spacer main body 20B in the width direction of the auxiliary top plates 36 and 36 'of these reinforcing members 30C and 30D, there are irregularities 28b formed on the peripheral edge of the through hole 28a of the top plate 28 of the spacer main body 20B. The fitting uneven part 36b is formed.

  Then, by fitting the unevenness 36b of the reinforcing members 30C and 30D and the unevenness 28b of the spacer body 20B, the position of the auxiliary air passage 32 of the reinforcing members 20C and 30D and the through hole 24 of the spacer body 20B are formed. The position of the facing air passage 22 matches.

  In the reinforcing member 30D having a short length, a plurality of positions where the auxiliary air passage 32 of the reinforcing member 30D and the air passage 32 facing the through hole 24 are matched by fitting the concaves and convexes 28b and 36b to each other. It can be selectively attached to.

  Since the unevenness 28b, 36b is formed in the main base spacer 10B, the position of the auxiliary ventilation path 32 of the short-length reinforcing member 30D and the position of the ventilation path 22 facing the through hole 24 of the spacer body 20B. It is possible to perform the positioning by a simple operation of simply fitting the concave and convex portions 28b and 36b without requiring a troublesome positioning operation of matching both positions while visually confirming. Therefore, workability when mounting the short reinforcing member 30D can be improved. Further, after the reinforcement member 30D is mounted, the mutual displacement between the reinforcement member 30D and the spacer main body 20B can be prevented by fitting the concaves and convexes 28b and 36b.

  In the embodiment shown in FIG. 8, the concave and convex portions 28b and 36b that can be fitted to each other are formed on the peripheral edge of the through hole 28a of the top plate 28 of the spacer body 20B and the auxiliary top plates 36 and 36 'of the reinforcing members 30C and 30D. Although the formed form is shown, it need not be such a form.

  For example, the width of the auxiliary top plates 36 and 36 ′ of the reinforcing members 30 C and 30 D is made shorter than the auxiliary partition wall portion 34 so that both ends of the auxiliary partition wall portion 34 protrude from the auxiliary top plates 36 and 36 ′, and the protrusion You may form in a concave shape so that the both ends of the made auxiliary partition part 34 may pinch | interpose the edge part of the partition part 26 which protrudes in the through-hole 28a of the top plate 28 of the said spacer main body 20B.

  Alternatively, without using the end portion of the partition wall portion 24 of the spacer body 20B to form the unevenness 28b, as shown in FIG. 2, without protruding the end portion of the partition wall portion 24 from the peripheral portion of the through hole 28a. Further, unevenness may be provided by forming a concave groove recessed in the width direction of the spacer body 20B in a portion where the partition wall portion 24 does not exist in the peripheral portion of the through hole 28a.

  In addition, the spacer main body and the reinforcing member in the base spacer of the present invention are not limited to the shapes shown in the above-described embodiments, and various modifications can be made.

  For example, as the spacer body, as shown in FIG. 9, the width in the width direction of the spacer body 20C on the top plate 28 is shortened so that both outer ends of each partition wall 24 protrude in the width direction, and the protrusion A bottom plate 29 that connects the lower ends of the partition walls 24 may be provided in the region.

  Further, as shown in FIG. 10, the upper end portions or the lower end portions of the adjacent partition wall portions 26 among the partition wall portions 26 of the spacer main body 20 </ b> D are alternately connected by the top plate 28 and the bottom plate 29. May be.

  In this case, the reinforcing member 30 </ b> F may also be configured such that the upper end portions or the lower end portions of the adjacent auxiliary partition walls 34 among the auxiliary partition walls 34 are connected by the auxiliary top plate 36 or the auxiliary bottom plate 37. preferable.
