Description

本発明は、ホゾ穴に柱のホゾを嵌め込んだときにホゾの先端面とその先端面と対向する基礎などの対向部との間の隙間を埋めるために配置するホゾ穴用調整体に関する。 The present invention relates to a mortise adjustment body arranged to fill a gap between a tip surface of a mortise and a facing portion such as a foundation facing the tip surface when a mortise of a pillar is fitted into the mortise hole. .

従来の木造住宅の軸組工法は、コンクリート製の基礎の上に、木製の土台を載せ、この土台の上に柱を立てる。柱の下端にはホゾが設けられ、土台にはホゾ穴が形成され、当該ホゾがホゾ穴に嵌め込まれて、柱と土台との結合が行われる。 In the conventional framework construction method for wooden houses, a wooden foundation is placed on a concrete foundation, and pillars are erected on this foundation. A tenon is provided at the lower end of the column, and a tenon hole is formed in the base, and the tenon is fitted into the tenon hole to connect the column and the base.

このような従来の軸組工法では、柱からの荷重を土台のホゾ穴周辺の上面で受ける構造になっているため、土台のホゾ穴周辺がその荷重によりめり込むように変形することがある。そこで、特許文献１には、基礎の上にベースプレートを敷きその上に、ホゾ穴が形成された土台を載せ、このホゾ穴に支柱を挿入し、土台上のホゾ穴周辺に耐圧板を敷き、この耐圧板上から下端にホゾが形成された柱を挿し込んで固定する技術が記載されている。これにより、耐圧板にかかる柱からの荷重を、支柱でベースプレートに伝えて土台を介さずに基礎に伝えることが可能となり、ホゾ穴周辺のめり込みを抑制することが可能となる。 In such a conventional framing method, the load from the pillar is received by the upper surface of the base around the mortise hole, so the base mortise hole may be deformed by the load. Therefore, in Patent Document 1, a base plate is laid on the foundation, a base with a mortise hole is placed on it, a support is inserted into the mortise hole, a pressure plate is laid around the mortise hole on the base, A technique of inserting and fixing a column having a tenon formed on the lower end of the pressure plate is described. As a result, the load applied to the pressure plate from the pillar can be transmitted to the base plate by the pillar and transmitted to the foundation without going through the foundation, making it possible to suppress the embedding around the mortise hole.

しかしながら、上記特許文献１に記載の技術においては、例えば、ホゾ穴の長さが誤差などにより支柱よりも長い場合、耐圧板が支柱により支持されずに単に土台上に載置された状態となる。さらにホゾの長さがホゾ穴よりも短い場合、ホゾの先端面とベースプレートとの間には隙間が生じる。これらの場合、柱からの荷重が耐圧板から土台にかかり、土台のホゾ穴周辺がめり込むという問題が生じる。 However, in the technique described in Patent Document 1, for example, when the length of the mortise hole is longer than the support due to an error, the pressure plate is simply placed on the base without being supported by the support. . Furthermore, if the length of the tenon is shorter than the tenon hole, a gap is generated between the tip surface of the tenon and the base plate. In these cases, the load from the pillar is applied to the base from the pressure plate, and there arises a problem that the periphery of the mortise hole of the base sinks.

そこで、本発明の目的は、柱がホゾ穴の周囲にめり込むのを抑制することが可能なホゾ穴用調整体を提供することである。 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a mortise adjuster that can prevent a post from becoming embedded around a mortise hole.

以下、本発明の一実施形態に係るホゾ穴用調整体１０が用いられた建物構造１００について、図１及び図２を参照しつつ以下に説明する。 A building structure 100 using a mortise adjusting body 10 according to an embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

本実施形態における建物構造１００は、図１及び図２に示すように、長尺な基礎１（例えば、布基礎）と、基礎パッキン２と、木製の土台３と、木製の柱４と、ホゾ穴用調整体１０とを含んでなる。基礎パッキン２は、基礎１の長手方向Ａに沿って長尺に延在した平板形状を有しており、基礎１上に配置されている。土台３は、長手方向Ａに沿って長尺に形成されており、基礎１とで基礎パッキン２を挟むように基礎パッキン２上に配置されている。また、土台３には、図２に示すように、ホゾ穴３ａが形成されている。ホゾ穴３ａは、上下方向Ｂに貫通している。なお、基礎パッキン２及び土台３は、基礎１に植設されたアンカーボルト、角座金及びナット（ともに図示せず）によって基礎１上に固定されている。 As shown in FIGS. 1 and 2, the building structure 100 in this embodiment includes a long foundation 1 (for example, a continuous foundation), a foundation packing 2, a wooden base 3, a wooden pillar 4, and a tenon. and a hole adjuster 10 . The base packing 2 has a flat plate shape elongated along the longitudinal direction A of the base 1 and is arranged on the base 1 . The base 3 is formed long along the longitudinal direction A and is arranged on the base packing 2 so as to sandwich the base packing 2 with the base 1 . Further, the base 3 is formed with a mortise hole 3a as shown in FIG. The mortise hole 3a penetrates in the vertical direction B. The foundation packing 2 and the base 3 are fixed on the foundation 1 by anchor bolts, square washers and nuts (none of which are shown) planted in the foundation 1 .

柱４は、図１に示すように、上下方向Ｂに沿って長尺に延在している。また、柱４には、図２に示すように、その下端面４ｂの中央から下方に突出した角柱状のホゾ４ａが形成されている。ホゾ４ａは、土台３のホゾ穴３ａに嵌合可能に形成されている。そして、柱４は、ホゾ４ａを土台３のホゾ穴３ａに嵌め込まれて土台３上に立設される。 The pillar 4 extends long in the vertical direction B, as shown in FIG. As shown in FIG. 2, the column 4 has a prism-shaped tenon 4a projecting downward from the center of its lower end surface 4b. The tenon 4a is formed so as to be fittable in the tenon hole 3a of the base 3. As shown in FIG. The pillar 4 is erected on the base 3 by fitting the tenon 4a into the tenon hole 3a of the base 3. - 特許庁

ホゾ穴用調整体１０は、図３に示すように、２枚のホゾ穴用調整板１１，１２と、ホゾ穴用ブロック１３とを有し、これらが上から順に分離可能に積層されて直方体形状に構成されている。これらホゾ穴用調整板１１，１２及びホゾ穴用ブロック１３は、いずれも同じ材質（例えば、ポリエチレン樹脂、ポリプロピレン樹脂、ポリスチレン樹脂などのポリオレフィン系樹脂、ＡＢＳなどのエンジニアリングプラスチックなどの合成樹脂、アルミニウム、ステンレスなどの金属、硬質ゴムなどを広く使用することができ、要するにホゾの先端面からかかる荷重によって圧し潰されない（ホゾの先端が減り込まない）程度の硬質を有するものであればよい。）から構成されているが、互いに異なる材料から構成されていてもよい。なお、ホゾ穴用調整板１１，１２及びホゾ穴用ブロック１３の材質としては、加工や取り扱いなどの面から、ポリプロピレン樹脂などのポリオレフィン系樹脂を用いるのがより好ましく、ポリオレフィン系樹脂などの合成樹脂を用いる場合には、炭酸カルシウムなどの充填材を適宜添加してもよい。 As shown in FIG. 3, the mortise adjustment body 10 has two mortise adjustment plates 11 and 12 and a mortise block 13, which are separably laminated in order from the top to form a rectangular parallelepiped. configured in shape. These mortise adjustment plates 11 and 12 and mortise block 13 are made of the same material (for example, polyolefin resin such as polyethylene resin, polypropylene resin, and polystyrene resin, synthetic resin such as engineering plastic such as ABS, aluminum, etc.). Metal such as stainless steel, hard rubber, etc. can be widely used, and in short, it is sufficient if it has a degree of hardness that is not crushed by the load applied from the tip surface of the tenon (the tip of the tenon is not reduced). Although constructed, they may be constructed from different materials. As the material of the mortise adjustment plates 11 and 12 and the mortise block 13, it is more preferable to use a polyolefin resin such as a polypropylene resin from the viewpoint of processing and handling, and a synthetic resin such as a polyolefin resin. When using, a filler such as calcium carbonate may be added as appropriate.

ホゾ穴用調整板１１，１２は、ホゾ穴３ａの平面形状及び平面サイズに対応しており、図３に示すように、いずれも同じ平面サイズの長方形平面形状を有する薄板部材からなる。ホゾ穴用調整板１１は、ホゾ穴用調整板１２よりも厚みが小さい。本実施形態におけるホゾ穴用調整板１１の厚みは１ｍｍとなっており、ホゾ穴用調整板１２の厚みは２ｍｍとなっているが、特に限定するものではない。つまり、これらホゾ穴用調整板１１，１２は互いに同じ厚みであってもよいし、ホゾ穴用調整板１１がホゾ穴用調整板１２よりも厚みが大きくてもよい。 The mortise adjusting plates 11 and 12 correspond to the plane shape and plane size of the mortise hole 3a, and as shown in FIG. The mortise adjustment plate 11 is thinner than the mortise adjustment plate 12 . The thickness of the mortise adjustment plate 11 in this embodiment is 1 mm, and the thickness of the mortise adjustment plate 12 is 2 mm, but the thickness is not particularly limited. That is, the mortise adjustment plates 11 and 12 may have the same thickness, or the mortise adjustment plate 11 may be thicker than the mortise adjustment plate 12 .

ホゾ穴用ブロック１３は、図３に示すように、ホゾ穴用調整板１１，１２と同じ平面形状及び平面サイズを有している。また、ホゾ穴用ブロック１３は、これらホゾ穴用調整板１１、１２よりも厚みが大きいブロック状部材からなる。本実施形態におけるホゾ穴用ブロック１３は、厚みが４０ｍｍ～８０ｍｍ程度であるが、ホゾ穴用調整板１１、１２よりも厚みが大きければどのような厚みであってもよい。 As shown in FIG. 3, the mortise block 13 has the same plane shape and plane size as those of the mortise hole adjustment plates 11 and 12 . The mortise hole block 13 is made of a block-shaped member having a greater thickness than the mortise hole adjustment plates 11 and 12 . The mortise block 13 in this embodiment has a thickness of about 40 mm to 80 mm, but may have any thickness as long as it is thicker than the mortise adjustment plates 11 and 12 .

本実施形態においては、図２に示すように、柱４のホゾ４ａがホゾ穴３ａに嵌め込まれたときのホゾ４ａの先端面４ａ１と基礎パッキン２（対向部）の上面２ａとの間の高さとホゾ穴用調整体１０の厚みとがほぼ同じになっており、ホゾ穴用調整体１０が先端面４ａ１と上面２ａとの間の隙間３ｂを埋めることが可能となっている。つまり、本実施形態におけるホゾ穴用調整体１０は、柱４のホゾ４ａを土台３のホゾ穴３ａに嵌め込む前に、２枚のホゾ穴用調整板１１，１２とホゾ穴用ブロック１３とが積層された状態でホゾ穴３ａに挿入される。その後に、ホゾ４ａがホゾ穴３ａに嵌め込まれて柱４が土台３上に立設される。このとき、ホゾ４ａの先端面４ａ１がホゾ穴用調整体１０（ホゾ穴用調整板１１の上面）と当接し、柱４からの荷重の一部がホゾ穴用調整体１０を介して基礎パッキン２に伝達される。つまり、柱４は土台３のみならず、ホゾ穴用調整体１０を介して基礎パッキン２によっても支持される。 In this embodiment, as shown in FIG. 2, when the tenon 4a of the column 4 is fitted into the tenon hole 3a, the height between the tip surface 4a1 of the tenon 4a and the upper surface 2a of the base packing 2 (opposing portion) is The thickness of the mortise hole adjusting body 10 is substantially the same as that of the mortise hole adjusting body 10, so that the mortise hole adjusting body 10 can fill the gap 3b between the tip surface 4a1 and the upper surface 2a. That is, the mortise adjusting body 10 in the present embodiment includes the two mortise adjustment plates 11 and 12 and the mortise block 13 before the mortise 4a of the post 4 is fitted into the mortise 3a of the base 3. are stacked and inserted into the mortise hole 3a. After that, the tenon 4a is fitted into the tenon hole 3a, and the column 4 is erected on the base 3. At this time, the tip surface 4a1 of the tenon 4a abuts on the mortise adjustment body 10 (the upper surface of the mortise adjustment plate 11), and part of the load from the column 4 is transmitted through the mortise adjustment body 10 to the foundation packing. 2. In other words, the column 4 is supported not only by the base 3 but also by the base packing 2 via the mortise adjusting body 10 .

以上に述べたように、本実施形態のホゾ穴用調整体１０によると、ホゾ４ａの長さとホゾ穴３ａの深さの少なくとも一方に誤差が生じていても、ホゾ穴３ａに嵌め込まれたホゾ４ａの先端面４ａ１と基礎パッキン２の上面２ａとの間の隙間３ｂを、ホゾ穴用調整体１０で埋めることが可能となる。このため、ホゾ穴用調整体１０を介してホゾ４ａの先端面４ａ１を基礎パッキン２で支持することが可能となる。したがって、柱４からの荷重をホゾ４ａの先端面４ａ１でも受けることが可能となって、柱４がホゾ穴３ａの周囲（土台３の上面であって柱４の下端面４ｂと対向する部分）にめり込むのを抑制することが可能となる。 As described above, according to the tenon adjustment body 10 of the present embodiment, even if there is an error in at least one of the length of the tenon 4a and the depth of the tenon hole 3a, the tenon fitted in the tenon hole 3a The gap 3b between the tip surface 4a1 of the base packing 2 and the upper surface 2a of the base packing 2 can be filled with the mortise hole adjusting body 10. - 特許庁Therefore, it is possible to support the tip surface 4a1 of the tenon 4a with the basic packing 2 via the adjusting body 10 for the tenon hole. Therefore, the load from the column 4 can be received by the tip surface 4a1 of the tenon 4a, and the column 4 is around the tenon hole 3a (the upper surface of the base 3 and the portion facing the lower end surface 4b of the column 4). It becomes possible to suppress sinking.

また、ホゾ穴用調整体１０が２枚のホゾ穴用調整板１１，１２を含む。このため、ホゾ４ａの先端面４ａ１と基礎パッキン２との間の隙間３ｂが若干小さくなってもホゾ穴用調整板１１、１２の枚数を減らすなどして、当該隙間３ｂに応じて調整することが可能となる。なお、ホゾ穴用調整体１０は、１又は３枚以上のホゾ穴用調整板を有していてもよい。これにおいても同様の効果を得ることが可能となる。 Further, the mortise adjustment body 10 includes two mortise adjustment plates 11 and 12 . Therefore, even if the gap 3b between the tip surface 4a1 of the tenon 4a and the basic packing 2 becomes slightly smaller, it is possible to adjust according to the gap 3b by, for example, reducing the number of the adjusting plates 11 and 12 for the tenon hole. becomes possible. The mortise adjustment body 10 may have one or more than three mortise adjustment plates. Also in this case, it is possible to obtain the same effect.

上述の実施形態においては、土台３のホゾ穴３ａに柱４のホゾ４ａが嵌め込まれたときの、ホゾ４ａの先端面４ａ１と基礎パッキン２の上面２ａとの間の隙間３ｂと、ホゾ穴用調整体１０の厚みとがちょうど対応しているが、当該隙間３ｂが大幅に小さくてもよい。このような場合、図４に示すように、第１変形例として、２枚のホゾ穴用調整板１１，１２からなるホゾ穴用調整体２１０を採用してもよい。つまり、上述のホゾ穴用調整体１０において、ホゾ穴用ブロック１３を有していないものと同様であってもよい。このようなホゾ穴用調整体２１０により、上下方向Ｂの高さが小さくなった隙間においても隙間を埋めることが可能となる。 In the above-described embodiment, the gap 3b between the tip surface 4a1 of the tenon 4a and the upper surface 2a of the basic packing 2 when the tenon 4a of the pillar 4 is fitted into the tenon hole 3a of the base 3, and the tenon hole Although the thickness of the adjusting body 10 corresponds exactly, the gap 3b may be significantly smaller. In such a case, as shown in FIG. 4, as a first modified example, a mortise adjustment body 210 comprising two mortise adjustment plates 11 and 12 may be employed. That is, it may be the same as the above-described mortise adjusting body 10 that does not have the mortise block 13 . With such a mortise adjusting body 210, it is possible to fill a gap even when the height in the vertical direction B is reduced.

これにより、上述の実施形態と同様に、ホゾ穴用調整体２１０を介してホゾ４ａの先端面４ａ１を基礎パッキン２の上面２ａで支持することが可能となる。したがって、柱４からの荷重をホゾ４ａの先端面４ａ１でも受けることが可能となって、柱４が土台３のホゾ穴３ａの周囲にめり込むのを抑制することが可能となる。 As a result, it becomes possible to support the front end surface 4a1 of the tenon 4a on the upper surface 2a of the basic packing 2 via the mortise hole adjuster 210, as in the above-described embodiment. Therefore, the tip surface 4a1 of the tenon 4a can also receive the load from the column 4, and it is possible to prevent the column 4 from sinking into the periphery of the tenon hole 3a of the base 3.

また、ホゾ穴用調整体２１０が厚みの異なる第１のホゾ穴調整板１１と第２のホゾ穴調整板１２とを含むため、ホゾ穴用調整体２１０の厚みを、ホゾ４ａの先端面４ａ１と基礎パッキン２の上面２ａとの間の隙間に応じて調整することが可能となる。なお、本変形例におけるホゾ穴用調整体２１０は、互いに同じ厚みのホゾ穴用調整板から構成されていてもよい。また、ホゾ穴用調整体は、３以上のホゾ穴用調整板から構成されていてもよい。このときのホゾ穴用調整板の厚みは互いに異なっていてもよいし、少なくとも２以上のホゾ穴用調整板の厚みが同じであってもよい。 Further, since the mortise adjustment body 210 includes the first mortise adjustment plate 11 and the second mortise adjustment plate 12 having different thicknesses, the thickness of the mortise adjustment body 210 can be adjusted to the tip surface 4a1 of the tenon 4a. and the upper surface 2 a of the base packing 2 . Note that the mortise adjustment body 210 in this modification may be composed of mortise adjustment plates having the same thickness. Further, the mortise adjustment body may be composed of three or more mortise adjustment plates. At this time, the thicknesses of the mortise adjusting plates may be different from each other, or at least two or more mortise adjusting plates may have the same thickness.

また、さらに、土台３のホゾ穴３ａに柱４のホゾ４ａが嵌め込まれたときの、ホゾ４ａの先端面４ａ１と基礎パッキン２の上面２ａとの間の隙間が小さくてもよい。このような場合、図５に示すように、第２変形例として、上述の１枚のホゾ穴用調整板１１だけを採用してもよい。このようなホゾ穴用調整板１１により、上下方向Ｂの高さが小さくなった隙間においても隙間を埋めることが可能となる。これにより、上述の実施形態と同様に、ホゾ穴用調整板１１を介してホゾ４ａの先端面４ａ１を基礎パッキン２の上面２ａで支持することが可能となる。したがって、柱４からの荷重をホゾ４ａの先端面４ａ１でも受けることが可能となって、柱４が土台３のホゾ穴３ａの周囲にめり込むのを抑制することが可能となる。 Furthermore, when the tenon 4a of the pillar 4 is fitted into the tenon hole 3a of the base 3, the gap between the tip surface 4a1 of the tenon 4a and the upper surface 2a of the basic packing 2 may be small. In such a case, as shown in FIG. 5, as a second modified example, only one mortise adjustment plate 11 may be employed. With such a mortise adjusting plate 11, it is possible to fill a gap even when the height in the vertical direction B is reduced. As a result, it becomes possible to support the front end surface 4a1 of the tenon 4a on the upper surface 2a of the basic packing 2 via the mortise adjustment plate 11, as in the above-described embodiment. Therefore, the tip surface 4a1 of the tenon 4a can also receive the load from the column 4, and it is possible to prevent the column 4 from sinking into the periphery of the tenon hole 3a of the base 3.

以上、本発明の好適な実施形態について説明したが、本発明は上述の実施形態に限られるものではなく、特許請求の範囲に記載した限りにおいて様々な変更が可能なものである。例えば、上述の実施形態及び各変形例においては、ホゾ穴用調整体１０，２１０及びホゾ穴用調整板１１は、土台３のホゾ穴３ａに柱４のホゾ４ａが嵌め込まれたときに形成される隙間に配置させていたが、胴差し、床梁及び小屋梁などの梁の貫通したホゾ穴に柱のホゾが上下から嵌め込まれた場合の一方（上方又は下方）のホゾの先端面と他方（下方又は上方）のホゾの先端面（対向部）との間の隙間に配置してもよいし、貫通していない有底形状のホゾ穴に柱のホゾを嵌め込んだ場合のホゾの先端面とホゾ穴の底部（対向部）との間の隙間に配置してもよいし、基礎パッキン２の上面２ａにホゾ穴に嵌合する突起が形成されている場合、ホゾと突起（対向部）との間の隙間に配置してもよいし、基礎パッキンが設けられていない場合、ホゾと基礎との間の隙間などに配置してもよい。要するに、ホゾ穴用調整体１０，２１０及びホゾ穴用調整板１１は、ホゾ穴に嵌め込まれたホゾの先端面と当該先端面と対向する対向部との間の隙間を埋めるために配置されるものであればよい。 Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, in the above-described embodiments and modifications, the mortise adjustment bodies 10 and 210 and the mortise adjustment plate 11 are formed when the mortise 4a of the pillar 4 is fitted into the mortise 3a of the base 3. However, when the mortise of the pillar is inserted from above and below into the mortise hole that penetrates the beam such as the dorsal, floor beam, and shed beam, the tip surface of one (upper or lower) tenon and the other It may be placed in the gap between the tip surface (opposing part) of the tenon (lower or upper), or the tip of the tenon when the tenon of the pillar is fitted into a bottomed tenon hole that does not penetrate It may be arranged in the gap between the surface and the bottom (opposing portion) of the tenon hole, or if a projection that fits into the tenon hole is formed on the upper surface 2a of the basic packing 2, the tenon and the projection (opposing portion ), or if the foundation packing is not provided, it may be placed in the clearance between the tenon and the foundation. In short, the mortise adjustment bodies 10 and 210 and the mortise adjustment plate 11 are arranged to fill the gap between the tip end surface of the tenon fitted in the mortise hole and the opposing portion facing the tip end surface. Anything is fine.
