Description

【０００１】
【発明の属する技術分野】
本発明は、布基礎及び土台を固定するための連結具に関する。
【０００２】
【従来の技術】
一般の木造住宅においては、布基礎の上に土台を載置し、該土台をアンカーボルト等で布基礎に緊結し、該土台の上に柱を立てるという施工方法が採用されている。ところが、近年、既設の住宅において、土台の緊結部における腐食や強震によって、土台が布基礎に対してずれたり、布基礎からずれ落ちたりして、建物の強度が損なわれるという問題が発生している。
【０００３】
そこで、布基礎及び土台を固定するための連結具が種々提案され、例えば特開平６−５７９６６号公報所載の発明が公知である。図４に示す如く、かかる公報所載の連結具５０は、断面Ｌ字形を有し、Ｌ字の長辺にコンクリートボルト等の挿通孔が、Ｌ字の短辺にネジ釘等の挿通孔がそれぞれ穿設されたものである。そして、二つの連結具５０，５０は、それぞれ長辺の内側面が布基礎５１及び土台５２の側面に、Ｌ字の短辺の内側面が土台５２の上面に当接するように配置され、長辺の挿通孔にコンクリートボルト５３，５３を打ち込むことで長辺が布基礎５１の側面に固定され、短辺の挿通孔にネジ釘５４，５４を打ち込むことで短辺が土台５２の上面に固定され、その結果、二つの連結具５０，５０に挟まれて布基礎及び土台が固定される。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の連結具は、布基礎の幅と土台の幅が全く同一であることを前提として作られたものであるため、両者の幅が異なる場合、即ち布基礎の幅に比べて土台の幅が狭い場合や、布基礎の幅に比べて土台の幅が広い場合、使いものにはならない。
【０００５】
また、上記従来の連結具は、二つ一組をもって土台の横ずれを防止する構成であるため、その分、取付け作業に時間がかかり、該作業が煩雑となる。新築の場合ならそれほど気にならないが、既設住宅の場合、作業者が暗くて狭い床下に潜り込んで作業しなければならず、作業者の負担は大きい。
【０００６】
さらに、上記従来の連結具は、短辺を土台の上面に固定する構成であるため、土台の高さが高くなるほど、コンクリートボルトとネジ釘との間隔が拡がり、横方向の力が弱くなって、曲がりやすくなるという問題がある。また、土台の上面に配置される短辺と柱とが干渉しないようにする必要もあるため、連結具の取付け箇所が制限されるという問題も生じてくる。
【０００７】
そこで、本発明は、上記問題に鑑みてなされたもので、土台の幅に関わらず取付け可能であり、取付け作業を容易に行うことができ、加えて布基礎及び土台への取付け強度を高めることができる連結具を提供することを課題とする。
【０００８】
【課題を解決するための手段】
上記課題を解決するため、本発明は、布基礎１２の側面に当接する第一当接板２と、土台１３の側面に当接する第二当接板３とを備え、第一当接板２及び第二当接板３が相互にスライド自在に連結されると共に、第一当接板２及び第二当接板３に、固定部材用の挿通孔４，５が穿設されてなり、且つ、前記第一当接板２及び前記第二当接板３の連結部２ｂ，３ｂに、緩衝部材８が介装されてなることを特徴とする連結具を提供する。
【０００９】
上記構成からなる連結具によれば、布基礎１２の側面と土台１３の側面との段差に応じて第一当接板２及び第二当接板３の相対位置を変え、かかる状態で取付け、固定部材をもって固定する。さすれば、第一当接板２が布基礎１２の側面に当接し且つ第二当接板３が土台１３の側面に当接した状態となり、布基礎１２及び土台１３は強固に固定されることとなる。
【００１０】
また、本発明は、請求項２記載の如く、前記第一当接板２が、縦長に形成され、且つ、前記第二当接板３が、横長に形成されてなる構成を採用することができる。
【００１２】
【発明の実施の形態】
以下、本発明の一実施形態に係る連結具について図面を参酌しつつ説明する。図１乃至図３に示す如く、本実施形態に係る連結具１は、布基礎１２の側面に当接する第一当接板２と、布基礎１２の上面に載置される土台１３の側面に当接する第二当接板３とを主要構成としている。尚、布基礎１２と土台１３の間には、両者間に所定隙間を設けて通気路を形成することを目的としたスペーサーを介装させる場合もある。
【００１３】
前記第一当接板２は、長方形状の鋼材を折り曲げ、縦面の当接部２ａと水平面の連結部２ｂとが直交して断面Ｌ字形を有している。当接部２ａは、縦長に形成されており、その上縁を布基礎１２の上縁近傍に合わせて該布基礎１２の側面に当接させる。また、当接部２ａには、上下二箇所位置に、固定部材としてのアンカーボルト１０を挿通させるための挿通孔４，４が穿設され、該挿通孔４，４越しに布基礎１２へアンカーボルト１０，１０を打ち込むことで当接部２ａが布基礎１２の側面に固定される。
【００１４】
前記第二当接板３は、Ｔ字状の鋼材を折り曲げ、縦面の当接部３ａと水平面の連結部３ｂとが直交して断面Ｌ字形を有している。当接部３ａは、横長に形成されており、その下縁を土台１３の下縁近傍に合わせて該土台１３の側面に当接させる。また、当接部３ａには、左右二箇所位置に、固定部材としてのネジ釘１１を挿通させるための挿通孔５，５が穿設され、該挿通孔５，５越しに土台１３へネジ釘１１，１１を打ち込むことで当接部３ａが土台１３の側面に固定される。
【００１５】
前記第一当接板２の連結部２ｂと前記第二当接板３の連結部３ｂとは、略同一の大きさを有し、互いに水平対向するように配置される。連結部２ｂには、板長方向に沿って長孔（図示しない）が穿設される一方、連結部３ｂには、円孔（図示しない）が穿設されている。そこで、この二つの孔に締結部材としてのボルト６を挿通し、締結部材としてのナット７を螺合させることにより、第一当接板２及び第二当接板３は、相互に（布基礎１２あるいは土台１３との接離方向に）スライド自在に連結され、適切な相対位置にして固定される。
【００１６】
より詳細に言及すると、前記第一当接板２の連結部２ｂと前記第二当接板３の連結部３ｂとの間には、板状のゴム製の緩衝部材８が介装され、該緩衝部材８の下面に形成された溝に第一当接板２の連結部２ｂが嵌まり込んでおり、バネ座金９を挿通させたボルト６を第一当接板２の連結部２ｂの下面から挿通させている。そして、第二当接板３の連結部３ｂの上面には、一のナット７が溶接により固着されており、ボルト６がこのナット７に螺合した状態で、別のナット７を上からボルト６に螺合させ、ダブルナットをもって第一当接板２及び第二当接板３をしっかりと締結する。
【００１７】
以上の如く、本実施形態に係る連結具は、布基礎１２の側面の上端部に当接固定される第一当接板２と、土台１３の側面の下端部に当接固定される第二当接板３とが、布基礎１２あるいは土台１３との接離方向にスライド自在に構成され、且つ、締結部材によって連結固定されるため、布基礎１２と土台１３とが同一幅（布基礎１２の側面と土台１３の側面とが面一）でなくとも、第一当接板２及び第二当接板３の相対位置を変位させることにより、第一当接板２の当接部２ａが布基礎１２の側面と当接し且つ第二当接板３の当接部３ａが土台１３の側面と当接する状態が得られ、従って、布基礎１２と土台１３とを確実に固定することができる。
【００１８】
尚、本発明は上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲にて種々の変更が可能である。例えば第一当接板２及び第二当接板３の具体的な形状は上記あるいは図面のものに限定されず、挿通孔４，５の数、穿設箇所も限定されない。ボルト６は上から下に向けて挿通させ、ナット７は第一当接板２の連結部２ｂの下面に固着させるものであってもよい。
【００１９】
また、防錆効果の観点から、第一当接板２及び第二当接板３の表面にメッキ処理（例えば亜鉛メッキ）を施すのがより好ましく、さらに、緩衝部材８は、第一当接板２及び第二当接板３の摺接による表面の傷付きを防止し、且つボルト６やナット７に瞬間的に掛かる荷重を吸収する機能を有して有効であるから、設けるのがより好ましい。
【００２０】
また、第一当接板２及び第二当接板３の固定手段、及び締結手段は、上記のものに限定されず、公知のもの全てを採用することができるのは言うまでもない。
【００２１】
さらに、例えば緩衝部材８を無くし、第一当接板２の連結部２ｂ又は第二当接板３の連結部３ｂの何れか一方の対向面に、波状の凹凸部を形成する一方、他方の対向面に、該凹凸部に係合する突起部を形成すれば、第一当接板２及び第二当接板３の位置ずれを確実に防止することができ、取付け強度を増すことができる。緩衝部材８を設ける場合、該緩衝部材８と第一当接板２及び緩衝部材８と第二当接板３との間に、かかる位置ずれ防止策を講じることとなる。
【００２２】
また、第二当接板３上の結露が土台１３に直接長時間接することによって、土台１３が腐朽する可能性があるため、第二当接板３の当接部２ａの内面にスペーサーを付設する（即ち、第二当接板３と土台１３との間にスペーサーを介装する）のがより好ましい。スペーサーの材質としては、板状ゴム、プラスチック等が考えられるが、ネジ釘１１に掛かる荷重を吸収することができる板状ゴムがより好ましい。
【００２３】
【発明の効果】
以上の如く、本発明は、布基礎の側面に当接する第一当接板と、土台の側面に当接する第二当接板とを備え、第一当接板及び第二当接板が相互にスライド自在に連結される構成を採用しているため、布基礎及び土台の幅が異なる場合であっても、第一当接板が布基礎の側面に当接し且つ第二当接板が土台の側面に当接した状態が得られ、布基礎及び土台を強固に固定することができる。
【００２４】
また、布基礎及び土台に対して固定部材を打ち込むことにより、第二当接板に対する土台の左右方向の移動を規制する構成であるため、従来のように二つ一組で施工する必要が無くなり、その分、取付けるべき連結具の数が半分になり、取付け作業を楽に行うことができる。
【００２５】
さらに、布基礎及び土台の側面同士を連結する構成であるため、土台の高さに関わらず、第一当接板における固定部材と第二当接板における固定部材との間隔を狭めることができ、その分、第一当接板の長さを短くできて、取付け強度の維持を図ることができ、また、連結具の一部が土台の上面に位置する構成でもないため、柱との干渉が生じる余地は無く、取付け箇所の制限を受けることもない。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connector for fixing a cloth foundation and a base.
[0002]
[Prior art]
In a general wooden house, a construction method is employed in which a base is placed on a cloth foundation, the base is tied to the cloth foundation with anchor bolts or the like, and columns are erected on the foundation. However, in recent years, in existing houses, there has been a problem that corrosion and strong earthquakes at the joints of the base cause the base to be displaced with respect to the fabric foundation, or to fall off from the fabric foundation, resulting in a problem that the strength of the building is impaired. I have.
[0003]
Therefore, various connecting tools for fixing the cloth foundation and the base have been proposed, and for example, the invention described in Japanese Patent Application Laid-Open No. 6-57966 is known. As shown in FIG. 4, the connecting device 50 described in the official gazette has an L-shaped cross section, and a long side of the L-shape has an insertion hole such as a concrete bolt, and a short side of the L-shape has an insertion hole such as a screw nail or the like. Each is perforated. The two connectors 50 and 50 are arranged such that the inner surface of the long side is in contact with the side surfaces of the cloth foundation 51 and the base 52 and the inner surface of the short side of the L is in contact with the upper surface of the base 52, respectively. The long side is fixed to the side surface of the cloth foundation 51 by driving the concrete bolts 53, 53 into the insertion holes on the sides, and the short side is fixed to the upper surface of the base 52 by driving the nails 54, 54 into the insertion holes on the short sides. As a result, the cloth base and the base are fixed by being sandwiched between the two connecting members 50, 50.
[0004]
[Problems to be solved by the invention]
However, since the above-mentioned conventional connecting tool is made on the assumption that the width of the cloth foundation and the width of the base are exactly the same, when the widths of both are different, that is, the base is smaller than the width of the cloth base. If the width of the base is narrow or the width of the base is wider than the width of the cloth foundation, it cannot be used.
[0005]
In addition, since the above-mentioned conventional connecting tool has a configuration in which the base is prevented from laterally displacing by a pair, the mounting work takes a corresponding amount of time and the work becomes complicated. In the case of a new building, this is not a concern, but in the case of an existing house, the worker must work under dark and narrow floors, and the burden on the worker is large.
[0006]
Furthermore, since the above-mentioned conventional connector has a configuration in which the short side is fixed to the upper surface of the base, as the height of the base increases, the distance between the concrete bolt and the screw nail increases, and the lateral force decreases. There is a problem that it is easy to bend. In addition, since it is necessary to prevent the short side and the column arranged on the upper surface of the base from interfering with each other, a problem arises in that the attachment location of the coupling tool is limited.
[0007]
In view of the above, the present invention has been made in view of the above-described problem, and can be mounted regardless of the width of the base, so that the mounting operation can be easily performed, and in addition, the mounting strength to the cloth foundation and the base can be increased. It is an object of the present invention to provide a connecting tool capable of performing the following.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention includes a first contact plate 2 contacting the side surface of the cloth base 12 and a second contact plate 3 contacting the side surface of the base 13. and second Totomoni contact plate 3 is coupled slidably to each other, the first contact plate 2 and the second contact plate 3, Ri through Ana 4,5 for the fixing member the name is drilled, and, wherein the first contact plate 2 and the second connecting portion 2b of the contact plate 3, the 3b, to provide a connector in which the buffer member 8, characterized in Rukoto such is interposed.
[0009]
According to the connecting tool having the above-described configuration, the relative positions of the first contact plate 2 and the second contact plate 3 are changed according to the level difference between the side surface of the cloth base 12 and the side surface of the base 13, and attached in such a state. Fix with a fixing member. Then, the first contact plate 2 comes into contact with the side surface of the cloth base 12 and the second contact plate 3 comes into contact with the side surface of the base 13, and the cloth base 12 and the base 13 are firmly fixed. It will be.
[0010]
Further, the present invention may adopt a configuration in which the first contact plate 2 is formed to be vertically long and the second contact plate 3 is formed to be horizontally long. it can.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a connector according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the connecting tool 1 according to the present embodiment includes a first abutting plate 2 abutting on a side surface of a cloth foundation 12 and a side surface of a base 13 placed on the upper surface of the cloth foundation 12. The main structure is a second contact plate 3 that comes into contact with the second contact plate. In some cases, a spacer may be interposed between the cloth base 12 and the base 13 so as to form a ventilation path with a predetermined gap therebetween.
[0013]
The first contact plate 2 is formed by bending a rectangular steel material, and has an L-shaped cross section in which a vertical contact portion 2a and a horizontal connection portion 2b are orthogonal to each other. The contact portion 2 a is formed in a vertically long shape, and an upper edge thereof is brought into contact with a side surface of the cloth base 12 with the upper edge being aligned with a vicinity of an upper edge of the cloth base 12. In the abutment portion 2a, insertion holes 4 and 4 for inserting an anchor bolt 10 as a fixing member are formed at two upper and lower positions, and anchors are attached to the cloth base 12 through the insertion holes 4 and 4. By driving in the bolts 10, 10, the contact portion 2 a is fixed to the side surface of the cloth foundation 12.
[0014]
The second contact plate 3 is formed by bending a T-shaped steel material, and has an L-shaped cross section in which a vertical contact portion 3a and a horizontal connecting portion 3b are orthogonal to each other. The contact portion 3 a is formed in a horizontally long shape, and its lower edge is brought into contact with the side surface of the base 13 so as to match the vicinity of the lower edge of the base 13. In the abutment portion 3a, insertion holes 5 and 5 for inserting screw nails 11 as fixing members are formed at two positions on the left and right, and screw nails are inserted into the base 13 through the insertion holes 5 and 5. The contact portions 3 a are fixed to the side surfaces of the base 13 by driving the bases 11 and 11.
[0015]
The connecting portion 2b of the first contact plate 2 and the connecting portion 3b of the second contact plate 3 have substantially the same size and are arranged so as to be horizontally opposed to each other. A long hole (not shown) is formed in the connecting portion 2b along the plate length direction, while a circular hole (not shown) is formed in the connecting portion 3b. Therefore, the first contact plate 2 and the second contact plate 3 are mutually connected (by the cloth base) by inserting a bolt 6 as a fastening member into these two holes and screwing a nut 7 as a fastening member. 12 or the base 13 so as to be slidably connected to each other and fixed at an appropriate relative position.
[0016]
More specifically, between the connecting portion 2b of the first contact plate 2 and the connecting portion 3b of the second contact plate 3, a plate-like rubber cushioning member 8 is interposed. The connecting portion 2b of the first contact plate 2 is fitted in a groove formed on the lower surface of the buffer member 8, and the bolt 6 into which the spring washer 9 is inserted is inserted into the lower surface of the connecting portion 2b of the first contact plate 2. Has been inserted from. One nut 7 is fixed to the upper surface of the connecting portion 3b of the second contact plate 3 by welding. With the bolt 6 screwed to the nut 7, another nut 7 is bolted from above. 6 and the first contact plate 2 and the second contact plate 3 are securely fastened with a double nut.
[0017]
As described above, the connector according to the present embodiment includes the first contact plate 2 that is fixed to the upper end of the side surface of the cloth foundation 12 and the second contact plate that is fixed to the lower end of the side surface of the base 13. The abutment plate 3 is configured to be slidable in the direction of contact and separation with the cloth base 12 or the base 13 and is connected and fixed by a fastening member, so that the cloth base 12 and the base 13 have the same width (the cloth base 12). Is not flush with the side surface of the base 13, by displacing the relative positions of the first contact plate 2 and the second contact plate 3, the contact portion 2 a of the first contact plate 2 becomes A state in which the side surface of the fabric base 12 is abutted and the contact portion 3a of the second abutment plate 3 abuts the side surface of the base 13 is obtained, and therefore, the cloth base 12 and the base 13 can be securely fixed. .
[0018]
Note that the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the present invention. For example, the specific shapes of the first contact plate 2 and the second contact plate 3 are not limited to those described above or those in the drawings, and the number of the insertion holes 4 and 5 and the location of the perforations are not limited. The bolt 6 may be inserted downward from above, and the nut 7 may be fixed to the lower surface of the connecting portion 2 b of the first contact plate 2.
[0019]
Further, from the viewpoint of the rust prevention effect, it is more preferable that the surfaces of the first contact plate 2 and the second contact plate 3 are plated (for example, galvanized). It is effective to prevent damage to the surface due to sliding contact between the plate 2 and the second contact plate 3 and to absorb the load instantaneously applied to the bolts 6 and the nuts 7. preferable.
[0020]
Further, the fixing means and the fastening means of the first contact plate 2 and the second contact plate 3 are not limited to those described above, and it goes without saying that any known means can be adopted.
[0021]
Furthermore, for example, the buffer member 8 is eliminated, and a corrugated uneven portion is formed on one of the opposing surfaces of the connecting portion 2b of the first contact plate 2 and the connecting portion 3b of the second contact plate 3, while the other is formed. By forming a projection on the opposing surface to be engaged with the uneven portion, it is possible to reliably prevent the first contact plate 2 and the second contact plate 3 from being displaced, and to increase the mounting strength. . In the case where the buffer member 8 is provided, a measure for preventing such displacement is taken between the buffer member 8 and the first contact plate 2 and between the buffer member 8 and the second contact plate 3.
[0022]
In addition, since the base 13 may rot due to the dew condensation on the second contact plate 3 coming into direct contact with the base 13 for a long time, a spacer is provided on the inner surface of the contact portion 2a of the second contact plate 3. (That is, a spacer is interposed between the second contact plate 3 and the base 13). As the material of the spacer, plate rubber, plastic, or the like can be considered, but plate rubber capable of absorbing the load applied to the screw nail 11 is more preferable.
[0023]
【The invention's effect】
As described above, the present invention includes the first contact plate that contacts the side surface of the cloth foundation and the second contact plate that contacts the side surface of the base, and the first contact plate and the second contact plate are The first contact plate abuts on the side surface of the cloth base and the second contact plate is mounted on the base even if the width of the cloth base and the base is different, since the structure is slidably connected to the base. And the cloth base and the base can be firmly fixed.
[0024]
In addition, since the fixing member is driven into the cloth base and the base to restrict the movement of the base in the left-right direction with respect to the second contact plate, it is not necessary to construct the base in pairs as in the related art. Accordingly, the number of connecting tools to be mounted is reduced by half, and the mounting operation can be performed easily.
[0025]
Furthermore, since the configuration is such that the side surfaces of the cloth foundation and the base are connected to each other, the distance between the fixing member in the first contact plate and the fixing member in the second contact plate can be reduced regardless of the height of the base. Therefore, the length of the first abutment plate can be shortened, and the mounting strength can be maintained. In addition, since there is no configuration in which a part of the connecting tool is located on the upper surface of the base, interference with the column can be achieved. There is no room for the occurrence of the problem, and there is no restriction on the mounting position.
