Description

本発明は、木造軸組家屋にその建築後に装着することができる補強装置に関する。   The present invention relates to a reinforcing device that can be mounted on a wooden framed house after its construction.

木造軸組家屋は、木材の経年変化に伴う収縮によりハゴ板、ボルト等による締め付け力が弱まり、建築物としての強度が低下するという問題を有する。通常、このように強度が低下した木造軸組家屋は鉛直軸まわりの捩じり力に対して脆くなり、地震、大風等により倒れやすくなる。この弊害を防止するため、上記木材の乾燥による収縮を吸収しうるバネを備えたハゴ板が近年用いられるようになった（例えば、特許文献１参照。）。   A wooden framed house has a problem that the tightening force by a hanger plate, a bolt, etc. is weakened due to shrinkage due to secular change of wood, and the strength as a building is lowered. Normally, a wooden framed house with such a reduced strength becomes fragile with respect to the torsional force around the vertical axis, and easily falls down due to an earthquake, a large wind, or the like. In order to prevent this harmful effect, a hago board provided with a spring capable of absorbing the shrinkage caused by drying of the wood has recently been used (for example, see Patent Document 1).

Collapse / breakdown of a group house It is possible to properly prevent the like. This is especially effective for wooden framed houses that have been reduced in strength over the years. Moreover, even if it is already completed wooden framed house, since it can be constructed from the outside of the house, it can be easily and quickly mounted without performing a large construction such as breaking the ceiling in the house itself.

次に、本発明の実施の形態を図面に基づいて説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図１に示すように、この補強装置は、二階建ての木造軸組家屋の外周に胴差１の上から複数本の形鋼製の横長フレーム部材２が無端状に連なるように当てられ、これらの横長フレーム部材２が相互に連結され、上記各横長フレーム部材２が上記胴差１に所望の箇所で止めネジ３により固定され、上記家屋の梁４が上記胴差１に接続された仕口部では、上記横長フレーム部材２が、上記胴差１を貫通し上記梁４へと螺入する固定ネジ５により固定されたものとして構成される。   As shown in FIG. 1, this reinforcing device is applied to the outer periphery of a two-story wooden framed house so that a plurality of shaped steel horizontal frame members 2 are endlessly connected from above the trunk difference 1. The horizontal frame members 2 are connected to each other, the horizontal frame members 2 are fixed to the trunk difference 1 at a desired position by a set screw 3, and the beam 4 of the house is connected to the trunk difference 1. The horizontal frame member 2 is configured to be fixed by a fixing screw 5 that passes through the trunk difference 1 and is screwed into the beam 4.

この二階建ての木造軸組家屋は、布基礎６、布基礎６上に固定される土台７、土台７上から起立する複数本の柱８、一階と二階との境界において複数本の柱８間を連結する胴差１、胴差間を連結する梁４等を備える。また、この木造軸組家屋はその外周等に図示しない壁を有する。外周の壁の表面は、図２及び図３に示すように、合板等からなる外装材９で覆われる。   This two-story wooden frame house has a cloth foundation 6, a base 7 fixed on the cloth foundation 6, a plurality of pillars 8 standing from the foundation 7, and a plurality of pillars 8 at the boundary between the first floor and the second floor. It is provided with a trunk difference 1 for connecting the gaps, a beam 4 for connecting the gaps, and the like. The wooden framed house has a wall (not shown) on its outer periphery. As shown in FIGS. 2 and 3, the surface of the outer peripheral wall is covered with an exterior material 9 made of plywood or the like.

横長フレーム部材２は、家屋の各壁面ごとに一本の長いものとして形成することもできるが、図１に示すように、望ましくは各種の適当な長さのものが用意され、それらが適宜組み合わされることで長い梁様のものとして用いられる。すなわち、所望の種類及び本数の横長フレーム部材２が長手方向に複数本組み合わされた状態で家屋の四囲に取り付けられる。   The horizontally long frame member 2 can be formed as one long one for each wall surface of the house. However, as shown in FIG. 1, various suitable lengths are preferably prepared, and these are combined appropriately. It is used as a long beam-like thing. That is, a desired type and number of horizontally long frame members 2 are attached to the four surroundings of the house in a state where a plurality of horizontally long frame members 2 are combined in the longitudinal direction.

図２及び図３に示すように、各横長フレーム部材２は、例えば形鋼である溝形鋼を所定の長さで切断し、両端に端板２ａを溶接等で固着することにより箱型に形成される。各横長フレーム部材２の底板２ｂには、各横長フレーム部材２を胴差１に固定するための止めネジ３、固定ネジ５等を通す通し孔１０が形成される。また、各端板２ａには、横長フレーム部材２同士を連結するためのボルト１１を通すための貫通孔（図示せず）が形成される。   As shown in FIGS. 2 and 3, each horizontally long frame member 2 is formed into a box shape by cutting, for example, a grooved steel, which is a shaped steel, into a predetermined length and fixing end plates 2a to both ends by welding or the like. It is formed. The bottom plate 2b of each horizontally long frame member 2 is formed with a through hole 10 through which a set screw 3, a fixing screw 5 and the like for fixing each horizontally long frame member 2 to the body difference 1 are passed. Each end plate 2a is formed with a through hole (not shown) through which a bolt 11 for connecting the horizontally long frame members 2 is passed.

各横長フレーム部材２は、図１乃至図３に示すように、胴差１に外装材９の上から当てられ、止めネジ３により胴差１に固定される。止めネジ３は、例えば図４（Ａ）に示すようなコーチボルトであり、このコーチボルトのセルフタッピングネジ部３ａが横長フレーム部材２の底板２ｂの通し孔１０を貫通し、ボルト頭３ｂが底板２ｂに当たるまで胴差１に螺入する。これにより、横長フレーム部材２はその底板２ｂが胴差１の側面に密着するように胴差１に対して固定される。   As shown in FIGS. 1 to 3, each horizontally long frame member 2 is applied to the body difference 1 from above the exterior material 9 and is fixed to the body difference 1 by a set screw 3. The set screw 3 is a coach bolt as shown in FIG. 4A, for example. The self-tapping screw portion 3a of the coach bolt penetrates the through hole 10 of the bottom plate 2b of the horizontally long frame member 2, and the bolt head 3b is the bottom plate. Screw into barrel difference 1 until it hits 2b. Thereby, the horizontally long frame member 2 is fixed to the trunk difference 1 so that the bottom plate 2b is in close contact with the side surface of the trunk difference 1.

梁４が胴差１に接続された仕口部では、横長フレーム部材２は胴差１を貫通し梁４へと螺入する固定ネジ５により固定される。この固定ネジ５としては、図４（Ａ）に示したようなコーチボルトを用いることも可能であるが、望ましくは図４（Ｂ）に示すようなコーチボルトが用いられる。   In the joint where the beam 4 is connected to the trunk difference 1, the horizontally long frame member 2 is fixed by a fixing screw 5 that passes through the trunk difference 1 and is screwed into the beam 4. As the fixing screw 5, a coach bolt as shown in FIG. 4 (A) can be used, but a coach bolt as shown in FIG. 4 (B) is preferably used.

この固定ネジ５であるコーチボルトは、セルフタッピングネジ部５ａと、ボルト頭５ｂと、ボルト頭５ｂからセルフタッピングネジ部５ａとは反対側に突出するネジ棒５ｃと、ネジ棒５ｃに螺合するナット５ｄとを具備する。図３に示すように、この固定ネジ５は、セルフタッピングネジ部５ａが胴差１に形成された貫通孔１２を通って梁４と螺合し、ボルト頭５ｂが外装材９の下孔１３を貫通して胴差１に当たり、ナット５ｄがネジ棒５ｃ上を螺進して横長フレーム部材２に当たることにより、胴差１に対し装着される。また、セルフタッピングネジ部５ａが通る貫通孔１２は胴差１のほぞ孔１４に挿入された柱８のほぞ１５をも貫通する。このように、固定ネジ５により横長フレーム部材２、胴差１、柱８のほぞ１５、梁４の四者が一体的に締め付けられることから、家屋はより強固に補強される。   The coach bolt as the fixing screw 5 is screwed into the self-tapping screw portion 5a, the bolt head 5b, the screw rod 5c protruding from the bolt head 5b to the side opposite to the self-tapping screw portion 5a, and the screw rod 5c. And a nut 5d. As shown in FIG. 3, the fixing screw 5 has a self-tapping screw portion 5 a screwed into the beam 4 through a through hole 12 formed in the trunk difference 1, and a bolt head 5 b being a lower hole 13 of the exterior material 9. The nut 5d is screwed on the screw rod 5c and hits the horizontally long frame member 2 by hitting the barrel difference 1, and is attached to the barrel difference 1. Further, the through hole 12 through which the self-tapping screw portion 5a passes also penetrates the tenon 15 of the column 8 inserted into the tenon hole 14 of the trunk difference 1. As described above, since the four members of the horizontally long frame member 2, the trunk difference 1, the tenon 15 of the column 8, and the beam 4 are integrally tightened by the fixing screw 5, the house is reinforced more firmly.

また、胴差１上で横長フレーム部材２の隣り合うもの同士は、端板２ａの通し孔（図示せず）に通されるボルト１１とナット１１ａにより強固に連結され一体化される。その場合、図２及び図３に示すように、端板２ａ，２ａ間に多少隙間を設けておき、締め付け力を加減することができるようにするのが望ましい。   Adjacent ones of the horizontally long frame members 2 on the body difference 1 are firmly connected and integrated by bolts 11 and nuts 11a that are passed through through holes (not shown) of the end plate 2a. In that case, as shown in FIGS. 2 and 3, it is desirable to provide a slight gap between the end plates 2a and 2a so that the tightening force can be adjusted.

横長フレーム部材２，２同士が家屋の角において隣接する箇所では、例えば横長フレーム部材２同士を直に連結し、或いは、端板２ａ，２ａ間にＬ形鋼等の適宜の連結材を介在させ、溶接、ボルト・ナット等により連結することができるが、この実施の形態では、図１に示すように、上記横長フレーム部材２とは異なる構造の縦長フレーム部材１６が用いられる。   In the place where the horizontally long frame members 2 and 2 are adjacent to each other at the corner of the house, for example, the horizontally long frame members 2 are directly connected to each other, or an appropriate connecting material such as L-shaped steel is interposed between the end plates 2a and 2a. However, in this embodiment, as shown in FIG. 1, a vertically long frame member 16 having a structure different from that of the horizontally long frame member 2 is used.

縦長フレーム部材１６は、図２及び図３に示すように、所定の長さで切断した形鋼である溝形鋼を二本用意し、それらの底板１６ａが９０度で交差するように溶接等により接合することにより作られる。溝形鋼の底板１６ａにはその長手方向すなわち柱８の縦方向の複数箇所に止めネジ３の通し孔１０が形成される。縦長フレーム部材１６の直交する二つの底板１６ａが柱８の直交する二面に当てられ、止めネジ３が各通し孔１０から柱８に向かって通されることにより、縦長フレーム部材１６が柱８の胴差１と交差する箇所に固定される。縦長フレーム部材１６は柱８が折れないように長めに形成される。   As shown in FIGS. 2 and 3, the vertically long frame member 16 is prepared by preparing two grooved steels, which are shaped steels cut to a predetermined length, and welding so that their bottom plates 16a intersect at 90 degrees. It is made by joining. Through holes 10 for the set screws 3 are formed in the bottom plate 16a of the channel steel at a plurality of locations in the longitudinal direction, that is, in the longitudinal direction of the column 8. Two orthogonal bottom plates 16a of the vertically long frame member 16 are brought into contact with two orthogonal surfaces of the pillar 8, and the set screws 3 are passed from the respective through holes 10 toward the pillar 8 so that the vertically long frame member 16 becomes the pillar 8. It is fixed at a location where it intersects with the body difference 1 of. The vertically long frame member 16 is formed long so that the pillar 8 does not break.

この縦長フレーム部材１６の側板１６ｂに対して上記横長フレーム部材２の端板２ａを直に連結することも可能であるが、この実施の形態では、図２及び図３に示すように、補助部材１７が縦長フレーム部材１６に連結され、縦長フレーム部材１６と一体化される。補助部材１７は上記横長フレーム部材２を短くしたものの一端の端板１７ａを側板の外側へと突出させ、この端板１７ａの突出した部分と側板との角に補強板１７ｂを溶接等により固定してなるもので、端板１７ａを縦長フレーム部材１６の側板１６ｂにボルト１１等で固定することにより縦長フレーム部材１６と一体化される。端板１７ａと側板１６ｂとの間にも多少隙間を設けておき、締め付け力を加減することができるようにしておくのが望ましい。   Although it is possible to directly connect the end plate 2a of the horizontally long frame member 2 to the side plate 16b of the vertically long frame member 16, in this embodiment, as shown in FIGS. 17 is connected to the vertically long frame member 16 and integrated with the vertically long frame member 16. Although the auxiliary member 17 has the horizontally long frame member 2 shortened, the end plate 17a at one end protrudes to the outside of the side plate, and the reinforcing plate 17b is fixed to the corner between the protruding portion of the end plate 17a and the side plate by welding or the like. Thus, the end plate 17a is integrated with the vertically long frame member 16 by fixing the end plate 17a to the side plate 16b of the vertically long frame member 16 with bolts 11 or the like. It is desirable to provide a slight gap between the end plate 17a and the side plate 16b so that the tightening force can be adjusted.

縦長フレーム部材１６は、補助部材１７と一体化された後で、あるいは別々に柱８と胴差１に止めネジ３で固定される。また、補助部材１７の他の端板１７ｃに対して上記横長フレーム部材２の端板２ａがボルト１１等で連結される。   The vertically long frame member 16 is fixed to the column 8 and the trunk difference 1 with the set screw 3 after being integrated with the auxiliary member 17 or separately. Further, the end plate 2a of the horizontally long frame member 2 is connected to the other end plate 17c of the auxiliary member 17 by a bolt 11 or the like.

このように、家屋の例えば四隅の柱８に胴差１と交差する箇所において縦長フレーム部材１６が取り付けられ、上記胴差１に沿って並べられ固定された横長フレーム部材２の端板２ａが縦長フレーム部材１６の端板１７ｃに連結されることにより、家屋の全外周が鋼製の無端状のフレームにより囲まれ補強されることとなる。   Thus, the vertically long frame member 16 is attached to the pillar 8 at the four corners of the house, for example, at the position intersecting the trunk difference 1, and the end plate 2a of the horizontally long frame member 2 arranged and fixed along the trunk difference 1 is vertically long. By being connected to the end plate 17c of the frame member 16, the entire outer periphery of the house is surrounded and reinforced by an endless frame made of steel.

図１に示すように、上記横長フレーム部材２と上記家屋の土台７又は布基礎６との間に、必要に応じて鋼製の筋交い部材１８が設けられる。筋交い部材１８は、例えばＬ形鋼の枠材１８ａを溶接等により四角形の枠型に連結し、対角同士を棒鋼等の筋交い材１８ｂで連結することにより形成される。図示例では、この筋交い部材１８が上記横長フレーム部材２と、土台７と、左右の柱８，８とで囲まれる箇所にあてがわれ、横長フレーム部材２と、土台７と、左右の柱８，８にそれぞれ止めネジ３で固定される。図１では筋交い部材１８が一箇所のみに取り付けられるが、望ましくは家屋の四囲の壁にそれぞれ取り付けられる。   As shown in FIG. 1, a steel bracing member 18 is provided between the horizontally long frame member 2 and the base 7 or cloth foundation 6 of the house as necessary. The bracing member 18 is formed, for example, by connecting an L-shaped steel frame member 18a to a quadrangular frame shape by welding or the like and connecting diagonals to each other with a bracing member 18b such as a bar steel. In the illustrated example, the bracing member 18 is applied to a portion surrounded by the horizontally long frame member 2, the base 7, and the left and right columns 8, 8, and the horizontally long frame member 2, the base 7, and the left and right columns 8. , 8 are fixed with set screws 3 respectively. In FIG. 1, the bracing members 18 are attached to only one place, but are preferably attached to the four walls of the house.

次に、上記構成の補強装置の作用について説明する。   Next, the operation of the reinforcing device configured as described above will be described.

各種の横長フレーム部材２と、縦長フレーム部材１６とを用意する。これらは家屋の胴差１に沿った全周を囲むことができるような本数分用意する。   Various horizontal frame members 2 and vertical frame members 16 are prepared. These are prepared in a number that can surround the entire circumference along the trunk difference 1 of the house.

縦長フレーム部材１６は図２に示すような補助部材１７を予め連結したものとして準備してもよいし、別々に用意してもよい。   The vertically long frame member 16 may be prepared as an auxiliary member 17 as shown in FIG. 2 connected in advance, or may be prepared separately.

図１に示すように、例えば横長フレーム部材２と縦長フレーム部材１６を家屋の回りに配置し、図２及び図３に示すように、縦長フレーム部材１６を各柱８における胴差１が交差する箇所に外装材９の上から当て、それぞれ止めネジ３で固定する。外装材９には必要に応じて予め止めネジ３を通す下孔１３をあけておく。   As shown in FIG. 1, for example, the horizontally long frame member 2 and the vertically long frame member 16 are arranged around the house. As shown in FIGS. 2 and 3, the vertically long frame member 16 intersects with the trunk difference 1 in each column 8. The parts are applied from above the exterior material 9 and fixed with set screws 3 respectively. In the exterior material 9, a pilot hole 13 through which the set screw 3 is passed is formed in advance as necessary.

続けて、横長フレーム部材２を外装材９の上から当ててそれぞれ止めネジ３で胴差１に対して固定する。外装材９には必要に応じて予め止めネジ３を通す下孔１３をあけておく。縦長フレーム部材１６，１６間に、横長フレーム部材２を一列で望ましくは全横長フレーム部材２間又は所望の全横長フレーム部材２間に多少隙間をあけるようにして配置し、縦長フレーム部材１６と横長フレーム部材２との端板１７ｃ，２ａ同士、隣接する横長フレーム部材２，２の端板２ａ，２ａ同士をボルト１１・ナット１１ａにより連結する。   Subsequently, the horizontally long frame member 2 is applied from above the exterior material 9 and fixed to the trunk difference 1 with the set screws 3. In the exterior material 9, a pilot hole 13 through which the set screw 3 is passed is formed in advance as necessary. Between the vertically long frame members 16, 16, the horizontally long frame members 2 are arranged in a line, preferably between all the horizontally long frame members 2 or between all the horizontally long frame members 2. The end plates 17c and 2a with the frame member 2 and the end plates 2a and 2a of the adjacent horizontally long frame members 2 and 2 are connected by bolts 11 and nuts 11a.

また、梁４が胴差１に接続された仕口部の箇所では、固定ネジ５を用いて横長フレーム部材２を胴差１に固定する。これには、まず外装材９、胴差１、柱８のほぞ１５に連通するように孔１３，１２をあけたうえで、固定ネジ５を孔１３，１２内に挿入し、ボルト頭５ｂに図示しない工具を掛けて固定ネジ５を回し、図３のごとくセルフタッピングネジ部５ａを梁内に螺進させる。ボルト頭５ｂが外装材９の下孔１３を貫通して胴差１に当たったところでねじ込みを停止する。ただし、ここまでの作業は横長フレーム部材２を胴差１に当てる前に行っておく必要がある。そして、ナット５ｄをネジ棒５ｃ上で螺進させ、横長フレーム部材２に押し付ける。かくて、固定ネジ５が胴差１に対し装着され、これにより横長フレーム部材２、胴差１、柱８のほぞ１５、梁４の四者が一体的に締め付けられる。   In addition, at the position of the joint where the beam 4 is connected to the trunk difference 1, the horizontally long frame member 2 is fixed to the trunk difference 1 using a fixing screw 5. In order to do this, first, holes 13 and 12 are opened so as to communicate with the exterior material 9, the trunk difference 1, and the tenon 15 of the column 8, and then the fixing screw 5 is inserted into the holes 13 and 12 to the bolt head 5b. A tool (not shown) is hung and the fixing screw 5 is rotated to screw the self-tapping screw portion 5a into the beam as shown in FIG. When the bolt head 5b passes through the lower hole 13 of the exterior material 9 and hits the trunk difference 1, the screwing is stopped. However, it is necessary to perform the operations up to this point before the horizontally long frame member 2 is brought into contact with the trunk difference 1. Then, the nut 5 d is screwed on the screw rod 5 c and pressed against the horizontally long frame member 2. Thus, the fixing screw 5 is attached to the trunk difference 1, whereby the horizontal frame member 2, the trunk difference 1, the tenon 15 of the column 8 and the beam 4 are integrally tightened.

また、上記横長フレーム部材２の胴差１上で隣り合うもの同士は、端板２ａの通し孔に通されるボルト１１とナット１１ａにより強固に締め付けられ連結される。   Further, the horizontally long frame members 2 adjacent to each other on the body difference 1 are firmly tightened and connected by bolts 11 and nuts 11a that are passed through the through holes of the end plate 2a.

かくて木造軸組家屋の四囲が無端の枠状に連結された各種フレーム部材２，１６で囲まれることにより、柱８、胴差１、梁４等の接合で脆弱化した箇所が補強される。このため、地震、台風等によりこの家屋に図１に示す如く鉛直軸ａの回りに捩じり力Ａ等が加わったとしても、横長フレーム部材２、縦長フレーム部材１６等による大きな抵抗力が生じ、家屋の倒壊、破壊等が防止される。   Thus, the four surroundings of the wooden framed house are surrounded by the various frame members 2 and 16 connected in an endless frame shape, so that the weakened part by joining the column 8, the trunk difference 1, the beam 4, etc. is reinforced. . Therefore, even if a torsional force A or the like is applied to the house around the vertical axis a as shown in FIG. 1 due to an earthquake, a typhoon or the like, a large resistance force is generated by the horizontally long frame member 2 and the vertically long frame member 16. , House collapse or destruction is prevented.

なお、本発明は上記実施の形態に限定されるものではなく、本発明の要旨の範囲内で種々変更可能である。例えば、上記実施の形態では、補強装置を二階建ての家屋について施したが、三階建て等についても適用可能である。また、上記実施の形態では柱を外装材で隠した大壁造りとして説明したが、柱を壁外に現した真壁造りの家屋に対しても本発明を適用可能である。また、上記実施の形態では横長フレーム部材を露出状態のままとしたが、横長フレーム部材を適当なカバーで覆うことも可能である。さらに、実施の形態では各種フレーム部材を形鋼で形成したが、その他の材料で形成してもよいし、箱型に限らずその他の形状に変更することも可能である。   In addition, this invention is not limited to the said embodiment, A various change is possible within the range of the summary of this invention. For example, in the above embodiment, the reinforcing device is applied to a two-storied house, but the present invention is also applicable to a three-story house. Moreover, although the said embodiment demonstrated as a large wall structure which concealed the pillar with the exterior material, this invention is applicable also to the true-walled house which showed the pillar outside the wall. In the above embodiment, the horizontally long frame member is left exposed, but it is also possible to cover the horizontally long frame member with an appropriate cover. Furthermore, in the embodiment, the various frame members are formed of the shape steel, but they may be formed of other materials, and can be changed to other shapes as well as the box shape.
