Description

本発明は、建造物の基礎とその上に載置される土台との間に介在する土台用スペーサに関するものである。   The present invention relates to a foundation spacer interposed between a foundation of a building and a foundation placed on the foundation.

従来、建造物の床下を換気するために、予め床下換気用の通気路が形成された土台用スペーサを基礎と土台との間に介在させることで、当該基礎と土台との間に床下換気用の通気路を確保することが知られている。   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.

例えば特許文献1には、上記のような土台用スペーサとして、当該土台用スペーサを幅方向に横切って通風可能な通気路が複数形成されたものが開示されている。この通気路は、土台用スペーサの長手方向に複数並んで設けられた幅方向に貫通する貫通孔によって、または土台用スペーサの下面に等間隔で形成された幅方向に延びる溝によって構成されている。   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. .

また、この土台用スペーサを載置する基礎上に土台を固定するためのアンカーボルトが突設されている場合にこのアンカーボルトを回避すべく、このアンカーボルトを挿通することが可能な貫通孔が予め設けられた土台用スペーサも知られている。   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.

例えば、特許文献2には、上記通気路を複数跨る大きさで土台用スペーサの長手方向に延びる略長方形状の貫通孔がその長手方向に複数並んで設けられ、その貫通孔にアンカーボルトが挿通可能な土台用スペーサが開示されている。   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.

この土台用スペーサによれば、その貫通孔によってアンカーボルトの位置に対応できるだけでなく、その貫通孔の容積分材料費を安く抑えることができる。
実開昭57−172810号 特開2002−70187号公報
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.
Japanese Utility Model Publication No.57-172810 JP 2002-70187 A

しかしながら、上記通気路及び貫通孔が設けられた土台用スペーサでは、その通気路及び貫通孔の分だけ土台用スペーサの横断面の断面積が小さくなっており、その断面部分に集中して土台からの荷重がかかる構造となっているため、その荷重の作用方向(すなわち上下方向)について圧縮荷重に対する強度を十分に確保することが難しい。   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).

しかも、アンカーボルトと土台用スペーサとの相対位置は必ずしも決まっていないので、その相対位置にかかわらずアンカーボルトを避けて土台用スペーサを設置できるようにするには、基礎長手方向に貫通孔を延長させたり、1つのスペーサに複数の貫通孔を設けていずれかの貫通孔に選択的にアンカーボルトを挿通できるようにしたりする必要があり、このようにして貫通孔の占有面積が増える分土台用スペーサ全体としてますます強度的に不利になる。   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.

特に、建造物の柱の直下に位置する部分では、土台用スペーサに付加される圧縮荷重が大きく、これに対応するには高い強度が求められる。   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.

このような強度を確保するには、土台用スペーサにおける通気路面積を削減してその肉厚部分を増やさざるを得ず、その分通気性能は低下することになる。   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.

本発明は、このような事情に鑑み、上記通気路が設けられた土台用スペーサにおいて、アンカーボルトの位置に柔軟に対応できるように基礎長手方向に延びる貫通孔または複数の貫通孔を設けるようにしながらも、通気路面積を抑えずに十分な強度を確保することができる土台用スペーサ及びその土台用スペーサを用いた土台構造を提供することを目的とする。   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.

It is a feature.

請求項6に係る発明は、建造物の基礎とその上に載置される土台との間に請求項1〜5のいずれか1項に記載の土台用スペーサが介在しており、その土台用スペーサにおけるスペーサ本体の貫通孔のうち上記土台に立設される柱の下に位置する貫通孔にのみ上記補強部材が嵌め込まれて、この補強部材によって少なくとも上記貫通孔における上記柱の直下に当たる部分が塞がれていることを特徴とする土台構造である。   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.

請求項7に係る発明は、請求項6に記載の土台構造において、上記スペーサ本体の貫通孔は、上記柱の直下の領域とその外側の領域とを跨るように位置しており、その柱の直下の領域にのみ部分的に補強部材が嵌め込まれていることを特徴とするものである。   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.

請求項1に係る発明によれば、基礎の長手方向に沿って延びるスペーサ本体に、アンカーボルトが挿通可能な貫通孔が当該スペーサ本体の長手方向に複数並んで設けられているので、そのうちの適当な貫通孔にアンカーボルトを通すことによってアンカーボルトの位置に柔軟に対応しながらスペーサ本体を設置することができる。しかも、アンカーボルトを通さない貫通孔、すなわち結果的に不要となる貫通孔には適宜補強部材を嵌め込んで、この補強部材とスペーサ本体の双方で荷重を受けるようにすることにより、スペーサ本体の強度的負担を軽減できる。従って、複数の貫通孔によってスペーサ本体を設置する際の良好な作業性を保ちながら、土台用スペーサの強度を向上させることができる。   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.

また、上記補強部材には、上記嵌め込み状態で上記スペーサ本体の貫通孔に臨む通気路とつながる補助通気路が設けられているので、当該補強部材を上記貫通孔内に嵌め込んでも通気路を塞ぐことがない。従って、良好な通気性能を確保しながら土台用スペーサの強度を向上させることができる。   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.

なお、上記補強部材を嵌め込む貫通孔は、仕様に応じて適宜選定可能であり、例えば土台に立設される柱の下に位置する貫通孔のように特に大きな荷重がかかる部分に位置する貫通孔にのみ補強部材を嵌め込むようにしてもよいし、アンカーボルトを通さない全ての貫通孔に嵌め込むようにしてもよい。   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.

請求項2に係る発明によれば、上記補強部材は、上記貫通孔内に嵌め込まれたときに当該貫通孔の略全体を塞ぐように、上記貫通孔と略同一形状に形成されているので、その貫通孔の略全域に亘ってスペーサ強度を復元することができる。   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.

請求項3に係る発明によれば、スペーサ本体に設けられたアンカーボルトが挿通可能な貫通孔は、当該スペーサ本体の長手方向に延びているので、アンカーボルトの位置のばらつきにも柔軟に対応することができる。そして、この貫通孔のうちアンカーボルトから外れる部分すなわち余る部分に補強部材を装着して、この補強部材でも荷重を受けるようにすることにより、スペーサ本体の強度的負担を軽減できる。従って、土台用スペーサの長手方向に延びる貫通孔によってスペーサ本体を設置する際の作業性を保ちながら、土台用スペーサの強度を向上させることができる。   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.

また、上記補強部材は当該補助通気路と上記貫通孔に臨む通気路とがつながる複数の位置に選択的に装着できるようになっているので、これらの位置のうちいずれの位置に上記補強部材を装着しても通気路を塞ぐことがなく、良好な通気性能を確保しながら土台用スペーサの強度を向上させることができる。さらに、アンカーボルトとスペーサ本体との相対位置によって補強部材を装着する位置を変更して、アンカーボルトを通す位置を変えることができる。   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.

請求項4に係る発明によれば、上記貫通孔の周縁部及び上記補強部材の外周縁部には、互いに嵌合可能な凹凸が形成されており、この凹凸同士を嵌合させることによって上記補強部材の補助通気路と上記スペーサ本体の貫通孔に臨む通気路とがつながる位置に上記補強部材が装着されるように構成されているので、補強部材の補助通気路の位置とスペーサ本体の貫通孔に臨む通気路の位置とを目視で確認しながらそれらの位置合わせを行うといった煩わしい位置決め作業を別段要せず、上記凹凸同士を嵌合させるだけの簡単な作業で当該位置決めを行うことができる。従って、補強部材を装着する際の作業性を向上させることができる。また、補強部材の装着後は、上記凹凸同士の嵌合によって、補強部材とスペーサ本体との相互の位置ずれを防止することもできる。   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.

請求項5に係る発明によれば、複数の貫通孔のうちからアンカーボルトを通すのに適当な貫通孔を選択することができ、かつ、上記貫通孔は上記スペーサ本体の長手方向に延びているので、アンカーボルトの位置にさらに柔軟に対応することができる。しかも、使用しない貫通孔には長い補強部材を嵌め込むとともに、使用する貫通孔のうちアンカーボルトが存在しない部分に短い補強部材を嵌め込むことにより、いずれの貫通孔についても補強することができる。   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.

請求項6に係る発明のように、大きな荷重のかかる柱の下に位置する貫通孔にのみ補強部材を嵌め込み、この補強部材によって少なくとも上記貫通孔における上記柱の直下に当たる部分を塞ぐようにすることにより、荷重の厳しい柱直下部分では十分な強度を確保しながら材料費を節約することができる。   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.

特に、請求項7に係る発明のように、上記貫通孔が柱直下の領域とその外側の領域とを跨るように位置している場合には、柱直下の領域にのみ部分的に補強部材を嵌め込むことにより、さらに材料費を抑えることができる。   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.

上記スペーサ本体20Aは、具体的には、図3に示すように、スペーサ本体20Aの長手方向に所定間隔をおいて並んで配列される複数の隔壁部26と、これらの隔壁部26の上端部同士をその配列方向に連結する天板28とを有している。   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.

上記各隔壁部26は、上記スペーサ本体20Aの幅方向に延びており、これらの各隔壁部26同士の間に、スペーサ本体20Aの幅方向両側に開口する通気路22が形成されている。そのため、スペーサ本体20Aは、その各通気路22を通じて当該スペーサ本体20Aの幅方向に横切って通風可能となっている。   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.

上記各隔壁部26の底面は、略同一平面上に位置しており、これらの底面が上述した基礎20の上面に載置可能なスペーサ本体20Aの下面を構成している。また、各隔壁部26の上端部は、上記天板28の下面に当該下面から垂れ下がるようにつながっている。   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.

上記天板28は、スペーサ本体20Aの長手方向に延びる長尺板状をなしている。この天板28の上面は、上記隔壁部26の底面が構成する平面と略平行な平面となっており、この上面が上述した土台50が載置可能なスペーサ本体20Aの上面20aを構成している。   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.

上記アンカーボルト挿通用の貫通孔24は、上記天板28を貫通する部分と、上記隔壁部26を分断する部分とから構成されている。   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.

上記貫通孔24の天板28を貫通する部分は、当該天板28を板厚方向に貫通する貫通孔28aからなっている。この貫通孔28aは、上記アンカーボルト45を挿通可能な大きさで、上記複数の隔壁部26を跨るように上記スペーサ本体20Aの長手方向に延びる長方形状であり、上記スペーサ本体20Aの長手方向に並ぶ複数の位置に形成されている。   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.

上記貫通孔24の隔壁部26を分断する部分では、上記隔壁部26が上記貫通孔28aにおけるスペーサ本体20Aの幅方向の寸法と略同寸法で中抜きされたように上記スペーサ本体20Aの幅方向に分断されている。   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.

また、上記貫通孔24内では、上記分断された隔壁部26によって通気路22がスペーサ本体20Aの長手方向に開放されて、隣接する通気路22と連通するようになっている。   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.

一方、上記補強部材30Aは、上記スペーサ本体20Aと同様に合成樹脂等で上記スペーサ本体20Aの貫通孔24内に嵌め込み可能な形状に形成されている。なお、本実施形態では、図1及び図2に示すように、上記補強部材30Aが上記貫通孔24内に嵌め込まれたときに当該貫通孔24の略全体を塞ぐことができるように、上記貫通孔24と略同一形状に形成されている。   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.

また、この補強部材30Aは、上記嵌め込み状態で上記スペーサ本体20Aの上面20aと略同一平面上に位置する上面30aと、上記嵌め込み状態で上記スペーサ本体20Aの貫通孔24に臨む通気路22とつながる補助通気路32とを有している。   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.

具体的には、図4に示すように、上記補強部材30Aは、上記スペーサ本体20Aの各隔壁部26と略等間隔でスペーサ本体20Aの長手方向に並んで配列される複数の補助隔壁部34と、上記スペーサ本体20Aの天板28に形成された貫通孔28aに嵌り込み可能な補助天板36とを有している。   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.

上記補助天板36は、上記スペーサ本体20Aの天板28の貫通孔28aと略同一形状の長方形状をなしており、この補助天板36が上記天板28の貫通孔28aに嵌り込むことにより、当該貫通孔28aが塞がれるようになっている。   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.

上記各補助隔壁部34の底面と、上記補助天板36の上面との間の距離は、上述したスペーサ本体20Aの下面と上面20aとの間の距離と略同一に設定されており、上記補強部材30Aが上記スペーサ本体20Aの貫通孔24に嵌め込まれた状態で、補助天板36の上面と上記スペーサ本体20Aの上面20aとが略同一平面上に位置するようになっている。そして、この補助天板36の上面が上述した補強部材30Aの上面30aを構成している。また、この補助天板36の下面に上記補助隔壁部34が連設されている。   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.

なお、上記補強部材30Aの上面30aとスペーサ本体20Aの上面30aとは完全な同一平面上に位置する必要はなく、その上に載置される土台50からの荷重を分散できる程度に近接していればよい。   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.

上記各補助隔壁部34は、上記スペーサ本体20Aの幅方向に延びており、この補助隔壁部34で挟まれてスペーサ本体20Aの幅方向両側に開口する空間によって、上述した補助通気路32が構成されている。   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.

また、上記各補助隔壁部34は、上記補強部材30Aが上記スペーサ本体20Aの貫通孔24に嵌め込まれたときに、当該貫通孔24に臨む上述したスペーサ本体20Aの分断された各隔壁部26と合致する位置に配置されている。そのため、上記補助通気路32は上記嵌め込み状態で上記スペーサ本体20Aの貫通孔24に臨む通気路22と合致して、当該補助通気路32及び上記通気路22を通じてスペーサ本体20Aをその幅方向に横切って挿通可能となっている。   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.

次に、上述した構成の土台用スペーサ10Aの設置要領及び作用を、図1及び図2を参照して説明する。   Next, the installation procedure and operation of the base spacer 10A configured as described above will be described with reference to FIGS.

まず、スペーサ本体20Aを基礎40の上面に載置する。この際、基礎40上に突設されたアンカーボルト45を、スペーサ本体20Aの複数の貫通孔24のうち適当な貫通孔24に通すようにする。   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.

上記貫通孔24は、複数設けられており、しかも上記スペーサ本体20Aの長手方向に延びているので、上記アンカーボルト45の位置及びそのばらつきに柔軟に対応しながらスペーサ本体20Aを設置することができる。   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. .

次に、上記アンカーボルト45を通した貫通孔24以外の貫通孔24に補強部材30Aを嵌め込む。この補強部材30Aを嵌め込む貫通孔24は、適宜選定可能であるが、本実施形態では、特に大きな荷重がかかる部分である土台50に立設される柱52の下に位置する貫通孔24にのみ補強部材30Aを嵌め込む。   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.

そして、スペーサ本体20Aの上面20aに土台40を載置する。   Then, the base 40 is placed on the upper surface 20a of the spacer body 20A.

上記補強部材30Aは、上記嵌め込み状態でスペーサ本体20Aの上面20aと略同一平面上に位置する上面30aを有しているので、土台50からの荷重は補強部材30Aとスペーサ本体20Aとに分散される。   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

このように、補強部材30Aとスペーサ本体20Aの双方で荷重を受けるようにすることにより、スペーサ本体20Aの強度的負担を軽減できるため、上記のような柱52の下の大きな荷重がかかる部分にアンカーボルト挿通用の貫通孔24が位置していてもその荷重に十分耐えられるようになる。従って、スペーサ本体20Aの長手方向に延びる複数の貫通孔24によってスペーサ本体20Aを設置する際の良好な作業性を保ちながら、土台用スペーサ10Aの強度を向上させることができる。   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.

なお、本実施形態では、柱52の下に位置する貫通孔24にのみ補強部材30Aを嵌め込んでいるので、荷重の厳しい柱52直下部分では十分な強度を確保しながら材料費を節約することができる。また、このように補強部材30Aを嵌め込む位置を限定することによって、現場での補強のための作業を極力少なくすることができる。   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.

また、上記補強部材30Aの補助通気路32は、上述したように上記嵌め込み状態でスペーサ本体20Aの貫通孔24に臨む通気路22と合致するように構成されているので、当該補強部材30Aを上記貫通孔24に嵌め込んでも通気路22を塞ぐことがなく、良好な通気性能を確保しながら土台用スペーサ10Aの強度を向上させることができる。   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.

さらに、上記補強部材30Aは、上記貫通孔24に嵌め込まれたときに当該貫通孔24の略全体を塞ぐように、上記貫通孔24と略同一形状に形成されているので、その貫通孔24の略全域に亘ってスペーサ強度を復元することができる。   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.

なお、上述した実施形態では、柱52の下に位置する貫通孔24に補強部材30Aを嵌め込んだ形態を示したが、アンカーボルト45を通さない全ての貫通孔24に嵌め込むようにしてもよい。   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.

また、図例では、上記貫通孔24におけるスペーサ本体20Aの長手方向両端部に位置する通気路22の上方を、補強部材30Aの補助天板36をその配列方向両端に位置する補助隔壁部34の側面から突出させて覆う形態を示したが、補強部材30Aの補助天板36を図5に示すように上記配列方向両端に位置する補助隔壁部34の側面で切断して、スペーサ本体20Aの天板28を上記貫通孔24の両端部に位置する隔壁部26の側面から突出させてもよい。   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.

さらには、上記実施形態では、補強部材30Aがスペーサ本体20Aの各隔壁部26と略等間隔でスペーサ本体20Aの長手方向に並んで配列される複数の補助隔壁部34を有し、この補助隔壁部34で挟まれて形成される補助通気路32がスペーサ本体20Aの貫通孔24に臨む通気路22に1つずつ合致する形態を示したが、必ずしもこのような形態である必要はない。   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.

例えば、スペーサ本体20Aの比較的に小さい荷重がかかる部分を補強する場合には、補強部材30Aの補助隔壁部34が並ぶ間隔をスペーサ本体20Aの隔壁部26が並ぶ間隔の2倍またはそれ以上の整数倍として、補強部材30Aの補助通気路32がスペーサ本体20Aの貫通孔24に臨む複数の通気路22につながるようにしてもよい。   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.

また、スペーサ本体20Aの天板28に形成される貫通孔28aの形状は、必ずしも長方形状である必要はなく、長手方向の両端が円弧状になっていてもよい。または、必ずしもスペーサ本体20Aの長手方向に延びている必要もなく、正方形状あるいは円形状であってもよい。このように貫通孔28aがスペーサ本体20Aの長手方向に延びていなくてもその長手方向に複数設けられていれば、アンカーボルト45の位置に柔軟に対応することができる。   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.

一方、スペーサ本体20Aの貫通孔24を、上記実施形態のように、当該スペーサ本体20Aの長手方向に延びる形状に形成した場合には、補強部材として、図6に示すように、上記スペーサ本体20Aの長手方向の寸法を上記スペーサ本体20Aの貫通孔24の長手方向の寸法よりも短くした補強部材30Bを採用することもできる。   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.

この補強部材30Bの長さは、当該補強部材30Bを上記スペーサ本体20Aの貫通孔24内における当該補強部材30Bの補助通気路34と上記貫通孔24に臨む通気路22とが合致する位置に装着した状態で、当該補強部材30Bに塞がれずに残った上記貫通孔24の一部に上記アンカーボルト45が挿通可能となるように設定されている。   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.

この補強部材30Bは、上述した貫通孔24の略全体を塞ぐことが可能な補強部材30A(以下、閉塞型補強部材30Aと呼ぶ)と比べ、スペーサ本体20Aの長手方向の寸法が短くなっただけであり、具体的には、上記閉塞型補強部材30Aの補助天板36よりも長さの短い長方形状の補助天板36´を有しているとともに、上述したのと同様の補助隔壁部34を有している。   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.

上記補助隔壁部34の数は、上記閉塞型補強部材30Aの補助隔壁部34の数すなわち上記スペーサ本体20Aの貫通孔24に臨む隔壁部26の数よりも補助天板36´の長さが短くなった分少なくなっており、この補助隔壁部34で挟まれて形成される補助通気路32の数も、上記スペーサ本体20Aの貫通孔24に臨む通気路22の数よりも少なくなっている。   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.

上記補助天板36´は、当該補助天板36´が嵌り込むスペーサ本体20Aの天板28の貫通孔28aの長さよりも短い長方形状であるため、上記補強部材30Bは、上記貫通孔28a内でスペーサ本体20Aの長手方向に移動可能であり、その補助通気路32と上記貫通孔24に臨む通気路22とが合致する複数の位置に装着できるようになっている。   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.

このように構成された補強部材30Bを用いれば、スペーサ本体20Aにおけるアンカーボルト45を通した貫通孔24のうちアンカーボルトから外れる部分すなわち余る部分に補強部材30Bを装着して、この補強部材30Bでも荷重を受けるようにすることにより、スペーサ本体20Aの長手方向に延びる貫通孔24によってアンカーボルト45の位置のばらつきに柔軟に対応できるという利点を確保しながら、このアンカーボルト45を通した貫通孔24についても補強することができる。   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.

また、上記補強部材30Bは上記補助通気路32と上記貫通孔24に臨む通気路22とが合致する複数の位置に装着できるようになっているので、これらの位置のうちいずれの位置に上記補強部材30Bを装着しても通気路22を塞ぐことがなく、良好な通気性能を確保しながら土台用スペーサ10Aの強度を向上させることができる。   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.

さらに、アンカーボルト45とスペーサ本体20Aとの相対位置によって補強部材30Bを装着する位置を変更して、アンカーボルト45を通す位置を変えることができる。   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.

なお、この補強部材30Bにおいても、上述した閉塞型補強部材30Aの変形例と同様に、補助通気路32を形成する補助隔壁部34が並ぶ間隔をスペーサ本体20Aの隔壁部26が並ぶ間隔の2倍またはそれ以上の整数倍として、補強部材30Aの補助通気路32がスペーサ本体20Aの貫通孔24に臨む複数の通気路22につながるようにしてもよい。   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.

また、この補強部材30Bと、上述した閉塞型補強部材30Aとを併用すれば、スペーサ本体20Aの長手方向に延びる複数の貫通孔24のうちアンカーボルト45を通す位置のみを残して他の部分を全て塞ぐことができ、土台用スペーサ10Aの全長に亘って有効にスペーサ強度を復元することができる。   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.

または、上記実施形態のように柱52の下に貫通孔24が位置しており、しかも貫通孔24の一部しか柱52の直下に位置しない場合には、この貫通孔24にのみ上記補強部材30Bを嵌め込んで上記貫通孔24における柱の直下に当たる部分を塞ぐようにしてもよい。その際に、その貫通孔24の一部と略一致する長さの補強部材30Bを用いて、柱の直下の領域にのみ部分的に補強部材30Bを嵌め込むようにすれば、荷重の厳しい柱52直下部分では十分な強度を確保しながら、その貫通孔24の略全体を塞ぐよりも材料費を抑えてコストダウンを図ることができる。   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.

なお、上記補強部材30Bとしては、複数種類の長さのもの製作しておくことも可能であるが、上記閉塞型補強部材30Aを、アンカーボルト45の位置に応じて所望の長さに切断して得るようにしてもよい。   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.

また、図7に示すように、上記閉塞型補強部材30Aの補助天板36における各隔壁部26の間に位置する部分にスリット36aを設けて、このスリット36aに沿って所望の位置で補助天板36を分割できるようにすることもできる。   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.

このようにスリット36aを設けることによって、種々の長さの補強部材30Bを製作しておく必要がなく、同一形状のものを量産することができるとともに、ケースに応じて分割して使用することができる。   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.

なお、上記実施形態では、スペーサ本体20Aの貫通孔24が複数設けられた形態を示したが、予めアンカーボルト45の位置が分かっている場合には、スペーサ本体20Aの長手方向に延びる貫通孔24を1つだけ設け、その貫通孔24に上述した補強部材30Bを嵌め込むようにしてもよい。   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.

また、上記補強部材30Bは、上記貫通孔24内における当該補強部材30Bの補助通気路32と上記スペーサ本体20Aの貫通孔24に臨む通気路22とが合致する位置に選択的に装着できることが好ましく、そのためには、補強部材30Bの外周縁部と上記貫通孔24の周縁部に互いに嵌合可能な凹凸を形成しておけばよい。   Further, it is preferable that the reinforcing member 30B can be selectively mounted at a position in the through hole 24 where the auxiliary air passage 32 of the reinforcing member 30B and the air passage 22 facing the through hole 24 of the spacer body 20A coincide. 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.

この凹凸が形成された形態の土台用スペーサ10Bを図8に示す。   FIG. 8 shows the base spacer 10B in the form in which the irregularities are formed.

この土台用スペーサ10Bにおけるスペーサ本体20Bでは、上述したスペーサ本体20Aに比べ、天板28におけるスペーサ本体20Bの幅方向の寸法が小さくなっているとともに、天板28に形成される貫通孔28aにおけるスペーサ本体20Bの幅方向の寸法が大きくなっている。   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.

そのため、各隔壁部26におけるスペーサ本体20Bの幅方向外側の端部が、上記天板28の外側に突出しているとともに、上記貫通孔28aが設けられた領域における分断された各隔壁部26の内側の端部は、上記貫通孔28aの周縁部から当該貫通孔28a内に突出している。   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.

また、上記各隔壁部26の上面は、上記天板28の上面と略同一平面上に位置して、上記天板28とともにスペーサ本体20Bの上面20aを構成している。このため、上記貫通孔28aにおけるスペーサ本体20Bの幅方向の周縁部には、当該貫通孔28a内に突出を繰り返す凹凸28bが形成されている。   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.

一方、上記土台用スペーサ10Bの補強部材としては、閉塞型補強部材30Cと、それよりも長さの短い補強部材30Dとを備えている。   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.

これらの補強部材30C,30Dの補助天板36,36´におけるスペーサ本体20Bの幅方向の外周縁部には、上記スペーサ本体20Bの天板28の貫通孔28a周縁部に形成された凹凸28bと嵌合可能な凹凸36bが形成されている。   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.

そして、上記補強部材30C,30Dの凹凸36bと上記スペーサ本体20Bの凹凸28bとを嵌合させることにより、上記補強部材20C,30Dの補助通気路32の位置と上記スペーサ本体20Bの貫通孔24に臨む通気路22の位置とが合致するようになっている。   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.

なお、長さの短い補強部材30Dでは、上記凹凸28b,36b同士を嵌合させることにより、当該補強部材30Dの補助通気路32と上記貫通孔24に臨む通気路32とが合致する複数の位置に選択的に装着できるようになっている。   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.

本土台用スペーサ10Bでは、このような凹凸28b,36bが形成されているので、長さの短い補強部材30Dの補助通気路32の位置とスペーサ本体20Bの貫通孔24に臨む通気路22の位置とを目視で確認しながら両位置を合致させるといった煩わしい位置決め作業を別段要せず、上記凹凸28b,36b同士を嵌合させるだけの簡単な作業で当該位置決めを行うことができる。従って、長さの短い補強部材30Dを装着する際の作業性を向上させることができる。また、補強部材30Dの装着後は、上記凹凸28b,36b同士の嵌合によって、補強部材30Dとスペーサ本体20Bとの相互の位置ずれを防止することもできる。   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.

なお、図8に示す実施形態では、互いに嵌合可能な凹凸28b,36bを、スペーサ本体20Bの天板28の貫通孔28a周縁部と補強部材30C,30Dの補助天板36,36´とに形成した形態を示したが、必ずしもそのような形態である必要はない。   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.

例えば、補強部材30C,30Dの補助天板36,36´の幅寸法を補助隔壁部34よりも短くして補助隔壁部34の両端部を補助天板36,36´から突出させるとともに、その突出させた補助隔壁部34の両端部を上記スペーサ本体20Bの天板28の貫通孔28a内に突出する隔壁部26の端部を挟み込むように凹状に形成してもよい。   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.

あるいは、上記スペーサ本体20Bの隔壁部24の端部を利用して凹凸28bを形成せずに、図2に示したように貫通孔28aの周縁部から隔壁部24の端部を突出させずに、貫通孔28aの周縁部における隔壁部24が存在しない部分にスペーサ本体20Bの幅方向に窪む凹溝を形成する等して凹凸を設けてもよい。   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.
