Description

本発明は、木造建物の耐震構造に関する。   The present invention relates to an earthquake resistant structure for a wooden building.

木造の建物を耐震構造とするのに、従来より、骨組のコーナー部に三角形の補強金具を取り付けたり、また前後に対向する一対の柱と梁材等の横材とで枠組みされる壁面側の骨組に筋交いを設ける方法が行なわれているが、このような方法だけでは、例えば震度５以上の大規模地震発生時に、特に横揺れに対して弱く、建物の倒壊を防ぐことができない。そこで、本願発明の発明者は、以前に、特許文献１に記載のような耐震構造を提案した。これは、前後に配置する胴差しと左右に配置する胴差しとが隅部の柱を挟んで水平面に沿って枠組みされた水平面側骨組の四隅部に夫々コーナー補強金具を取り付け、この四隅部の対角線状に対向するコーナー補強金具間に水平面用平筋交いを水平に掛け渡すようにしたものである。この構造によれば、比較的簡単な施工により、大規模地震発生の際の特に横揺れに十分耐えられて、木造建物の倒壊を防止することができる。
特開２００３−３３６３１７号公報 To make a wooden building an earthquake resistant structure, it has traditionally been possible to attach triangular reinforcing brackets to the corners of the frame, or on the wall side that is framed by a pair of pillars facing each other and a cross member such as a beam. A method of providing braces to the frame has been performed. However, such a method alone is particularly vulnerable to rolling when a large-scale earthquake with a seismic intensity of 5 or more occurs, and cannot prevent the collapse of the building. Therefore, the inventors of the present invention have previously proposed an earthquake resistant structure as described in Patent Document 1. This is because corner reinforcement brackets are attached to the four corners of the horizontal plane frame, in which the torso arranged in the front and rear and the torso arranged in the left and right are framed along the horizontal plane with the pillars at the corners sandwiched, respectively. A horizontal plane crossing is horizontally routed between diagonally facing corner reinforcing brackets. According to this structure, a relatively simple construction can sufficiently withstand the rolling especially in the event of a large-scale earthquake, and the collapse of the wooden building can be prevented.

The portion is connected to the side plate extending portion 18 of the corner reinforcing metal fitting 9 through the bolt insertion hole 22 by a bolt 36 and a nut 37 (see FIG. 6), and the other end portion is a stud 2 as shown in FIG. For example, it is fixed by a nail at the corner of the large pull 5. As for the other end portion of the strip-shaped plate member 35, for example, a triangular reinforcing metal member 14 is attached to the inner corner portion of the stud 2 and the large pull 5, and the other end portion of the strip-shaped plate member 35 is bolted to the triangular reinforcing metal member 14. You may stop it.

The right-angle plate piece 38 is composed of a right-angle plate piece 38 that is supported in contact and a triangular plate 39 that reinforces this right-angle plate piece 38. 40 is provided, and the triangular plate 39 is provided with a bolt insertion hole 32 for bolting the belt-like plate material 29 of the wall surface side bracing 12.

上記のように構成される耐震構造の施工にあたっては、先ず、図１に示すような水平面側骨組Ａの各隅部において互いに直交する胴差し６，７の夫々所定位置にボルト挿通孔３４（図５及び図６参照）を穿設する。そして、各隅部にコーナー補強金具９を嵌め込むと共に、図６に示すように、コーナー補強金具９の上部三角形補強板１６側に設けてある補強金具仮止め用突片２４を胴差し６，７の夫々上端面に支持させ、各突片２４の釘孔２３より胴差し６，７に釘４１を打ち込むことによって、コーナー補強金具９を仮止めする。尚、釘４１は、後から抜き取るため、その一部分だけ打ち込むようにする。   In the construction of the seismic structure constructed as described above, first, bolt insertion holes 34 (see FIG. 1) are respectively provided at predetermined positions of the body inserts 6 and 7 orthogonal to each other at each corner of the horizontal plane side frame A as shown in FIG. 5 and FIG. 6). Then, the corner reinforcing metal fittings 9 are fitted into the respective corners, and as shown in FIG. 6, the reinforcing metal fitting temporary fixing protrusions 24 provided on the upper triangular reinforcing plate 16 side of the corner reinforcing metal fittings 9 are inserted into the body 6, 7 is supported by the upper end surface of each of the projections 24, and nails 41 are driven into the barrels 6 and 7 from the nail holes 23 of the projecting pieces 24, thereby temporarily fixing the corner reinforcing metal fittings 9. In addition, since the nail 41 is extracted later, only a part of the nail 41 is driven.

こうしてコーナー補強金具９を水平面側骨組Ａの隅部所定位置に仮止めした後、図６に示すように胴差し６，７のボルト挿通孔３４から、直角側板１５の各側板部１５ａに設けてあるボルト挿通孔１９にボルト４２を挿通して、その突出端部にナット４３を螺合し、締め付けることにより、コーナー補強金具９を水平面側骨組Ａの各隅部に取り付け固定する。その後、前記各突片２４の釘孔２３より打ち込んだ仮止め用の釘４１を抜き取る。   After the corner reinforcing bracket 9 is temporarily fixed at a predetermined position on the corner of the horizontal plane side frame A, it is provided on each side plate 15a of the right side plate 15 from the bolt insertion holes 34 of the barrels 6 and 7, as shown in FIG. The bolt 42 is inserted into a certain bolt insertion hole 19, the nut 43 is screwed into the protruding end portion, and the corner reinforcing metal fitting 9 is attached and fixed to each corner of the horizontal plane side frame A by tightening. Thereafter, the temporary fixing nail 41 driven out from the nail hole 23 of each protruding piece 24 is extracted.

上記のように水平面側骨組Ａの四隅部に夫々コーナー補強金具９を取り付けたならば、これら４つのコーナー補強金具９…の対角線方向に対向するものどうし間に水平面側筋交い１０を水平に掛け渡す。この水平面側筋交い１０の掛け渡しにあたっては、対角線方向に対向して位置する２つのコーナー補強金具９，９の一方のコーナー補強金具９の下部三角形補強板１７の下面側に、水平面側筋交い１０の一端側の取付プレート２６を当て付けて、その三角形補強板１７のボルト挿通孔２０から取付プレート２６のボルト挿通孔にボルト２７を通してナット２８で締め付けることにより、水平面側筋交い１０の一端部を一方のコーナー補強金具９に取り付け、またこの水平面側筋交い１０の他端側の取付プレート２６も同様にして他方のコーナー補強金具９の下部三角形補強板１７にボルト２７・ナット２８で取り付ける。   If the corner reinforcing brackets 9 are attached to the four corners of the horizontal plane side frame A as described above, the horizontal plane side braces 10 are horizontally spanned between the diagonally facing portions of the four corner reinforcing brackets 9. . When this horizontal plane side brace 10 is passed over, the horizontal plane side brace 10 is placed on the lower surface side of the lower triangular reinforcing plate 17 of one corner reinforcing bracket 9 of the two corner reinforcing brackets 9, 9 positioned opposite to each other in the diagonal direction. A mounting plate 26 on one end side is applied, and a bolt 27 is passed from the bolt insertion hole 20 of the triangular reinforcing plate 17 to the bolt insertion hole of the mounting plate 26 with a nut 28 to tighten one end of the horizontal plane bracing 10 on one side. The mounting plate 26 is attached to the corner reinforcing bracket 9, and the mounting plate 26 on the other end side of the horizontal plane bracing 10 is similarly attached to the lower triangular reinforcing plate 17 of the other corner reinforcing bracket 9 with bolts 27 and nuts 28.

こうして水平面側骨組Ａの四隅部にある４つのコーナー補強金具９…の対角線方向に対向するものどうし間に夫々水平面側筋交い１０を水平に掛け渡した後、各水平面側筋交い１０のターンバックル１１を回して、丸棒材２５を緊張させる。   In this way, after horizontally laying the horizontal plane side braces 10 between the diagonally facing portions of the four corner reinforcing brackets 9 at the four corners of the horizontal plane side frame A, the turnbuckles 11 of the horizontal plane side braces 10 are arranged. Turn to tension the round bar 25.

次に、図２に示すように、水平面側骨組Ａの胴差し６，７、柱１及び間柱２を含む壁面に沿って枠組み形成されている壁面側骨組Ｂの、前記コーナー補強金具９と対角線状に対向する隅部に三角補強金物１４を取り付け、この三角補強金物１４とコーナー補強金具９とに亘って壁面側筋交い１２を掛け渡す。即ち、三角補強金物１４は柱１と大引き５との内隅部に嵌め込んでボルト止めし、壁面側筋交い１２は、その帯状板材２９の一端部をコーナー補強金具９の側板延設部１８にボルト３０止めし、他端部を三角補強金物１４にボルト３３止めした後、ターンバックル１１を回して帯状板材２９を緊張させる。また、壁面側筋交い１３の一端部をコーナー補強金具９の側板延設部１８にボルト３６止めし、その他端部を間柱２と大引き５との隅部に例えば釘止め等によって取り付ける。   Next, as shown in FIG. 2, the corner reinforcing bracket 9 and the diagonal line of the wall surface side frame B formed in a frame along the wall surface including the trunks 6 and 7 of the horizontal surface side frame A, the columns 1 and the intercolumns 2. A triangular reinforcing metal member 14 is attached to the corners facing each other in a shape, and the wall surface side braces 12 are bridged over the triangular reinforcing metal member 14 and the corner reinforcing metal fitting 9. That is, the triangular reinforcing metal fitting 14 is fitted into the inner corner of the pillar 1 and the large pull 5 and bolted, and the wall side bracing 12 is connected to one end of the belt-like plate material 29 at the side plate extending portion 18 of the corner reinforcing bracket 9. The bolt 30 is fastened to the other end, and the other end portion is fastened to the triangular reinforcing metal 14 with the bolt 33, and then the turnbuckle 11 is turned to tension the belt-like plate material 29. Further, one end of the wall side bracing 13 is fixed to the side plate extending portion 18 of the corner reinforcing bracket 9 with a bolt 36, and the other end is attached to the corner between the stud 2 and the large pull 5 by, for example, nailing.

図２は胴差し７の下方側に形成される壁面側骨組Ｂの補強構造を図示しているが、この図２に示す胴差し７の上方側に形成されるの補強構造も、この図２に示す補強構造と同様に構成される。即ち、図２の上部側及び図３に一部示すように胴差し７と柱１との内隅部に三角補強金物１４をボルトで取り付け、この三角補強金物１４と対角線状に位置する壁面側骨組Ｂの隅部に取り付けられているコーナー補強金具９の側板延設部１８と、前記三角補強金物１４との間に壁面側筋交い１２，１３を取り付ければよい。また、胴差し７の下方側に形成されていて前後又は左右に隣り合う各壁面側骨組Ｂの補強構造も上記同様に構成される。   FIG. 2 shows a reinforcing structure of the wall surface side frame B formed on the lower side of the trunk 7, but the reinforcing structure formed on the upper side of the trunk 7 shown in FIG. It is comprised similarly to the reinforcement structure shown in FIG. That is, as shown in part in FIG. 2 and part of FIG. 3, a triangular reinforcing metal 14 is attached to the inner corners of the barrel 7 and the pillar 1 with bolts, and the side of the wall located diagonally to the triangular reinforcing metal 14 What is necessary is just to attach the wall surface side bracings 12 and 13 between the side plate extending part 18 of the corner reinforcement metal fitting 9 attached to the corner of the frame B and the triangular reinforcing metal piece 14. Further, the reinforcing structure of each wall surface side frame B formed on the lower side of the trunk 7 and adjacent to the front and rear or the left and right is also configured in the same manner as described above.

上記のような耐震構造によれば、前後に配置する胴差し６と左右に配置する胴差し７とが隅部の柱１を挟んで水平面に沿って枠組みされた水平面側骨組Ａの四隅部に夫々コーナー補強金具９を取り付け、この四隅部の対角線状に対向するコーナー補強金具９，９間に水平面側筋交い１０を水平に掛け渡して、各水平面側筋交い１０にターンバックル１１を設けたものであるから、水平面側骨組Ａは、四隅部に夫々取り付けたコーナー補強金具１２による補強作用と、これら４つのコーナー補強金具１２に対角線状に掛け渡してターンバックル１４で緊張させた１対の水平面側筋交い１０，１０による補強作用との相乗効果によって、きわめて堅固な剛体構造となる。   According to the seismic structure as described above, the body insert 6 arranged at the front and the back and the body insert 7 arranged at the left and right are arranged at the four corners of the horizontal plane frame A in which the pillar 1 at the corner is sandwiched along the horizontal plane. Each corner reinforcing bracket 9 is attached, and a horizontal plane side brace 10 is horizontally placed between the corner reinforcing brackets 9 and 9 facing diagonally at the four corners, and a turn buckle 11 is provided on each horizontal plane side brace 10. Therefore, the horizontal plane side frame A has a reinforcing action by the corner reinforcing brackets 12 attached to the four corners, and a pair of horizontal plane sides that are diagonally stretched over the four corner reinforcing brackets 12 and are tensioned by the turnbuckles 14. Due to the synergistic effect of the reinforcement by the braces 10, 10, a very rigid structure is obtained.

また、前記胴差し６，７及び柱１を含む壁面に沿って枠組みされた壁面側骨組Ｂの柱１，１間に壁面側筋交い１２，１３を掛張し、これら壁面側筋交い１２，１３の夫々一端部を前記コーナー補強金具９に取り付けるているから、壁面側骨組Ｂは壁面側筋交い１２，１３により補強されて、水平面側骨組Ｂと同様に剛体構造となる。従って、このような水平面側骨組Ａ及び壁面側骨組Ｂによって構成される建物躯体は、例えば震度５以上の大規模地震の発生により、地盤が横揺れして躯体Ｋに大きな水平荷重がかかっても、損壊したり倒壊する可能性がきわめて少なくなる。   Further, the wall surface side bracings 12 and 13 are stretched between the columns 1 and 1 of the wall surface side frame B framed along the wall surface including the torso 6, 7 and the column 1, and the wall surface side bracings 12 and 13 are Since one end of each is attached to the corner reinforcing bracket 9, the wall surface side frame B is reinforced by the wall surface side bracings 12, 13 and has a rigid structure like the horizontal surface side frame B. Therefore, the building frame constituted by such a horizontal plane side frame A and the wall side frame B, even if a large horizontal load is applied to the frame K due to the ground rolling due to the occurrence of a large-scale earthquake having a seismic intensity of 5 or more, for example. , The possibility of breaking or collapsing is very low.

そして、この耐震構造では、壁面側骨組Ｂの柱１，１間に掛張される壁面側筋交い１２，１３の一端部を前記コーナー補強金具９に取り付けることによって、１個のコーナー補強金具９で水平面側筋交い１０と壁面側筋交い１２，１３が取り付けできるから、部材点数が少なくなり、構造の簡素化が図られることになる。   In this seismic structure, one end of the wall-side bracings 12 and 13 stretched between the columns 1 and 1 of the wall-side frame B is attached to the corner reinforcing bracket 9, thereby Since the horizontal side bracing 10 and the wall side bracings 12 and 13 can be attached, the number of members is reduced and the structure is simplified.

また、この耐震構造に使用するコーナー補強金具９は、水平面側骨組Ａの各隅部で互いに直交する胴差し６，７の内側面に当接する直角側板１５と、この直角側板１５の上下両端部に夫々水平に配設される上下一対の三角形補強板１６，１７と、直角側板１５の夫々側板部１５ａ，１５ａの下端から延設した側板延設部１８，１８とからなるもので、直角側板１５を胴差し６，７にボルト４２止めし、上下何れかの三角形補強板１６，１７に水平面側筋交い１０の一端部をボルト２７止めし、側板延設部１８に壁面側筋交い１２，１３の一端部をボルト３０，３６止めするようにしているから、構造的にきわめて頑強で、大きな外力に十分に耐えることができ、しかも水平面側骨組Ａの隅部に対する取付け、水平面側筋交い１０の取付け、及び壁面側筋交い１２，１３の取付けが夫々簡単容易となって、耐震構造の施工能率の向上を図ることができる。   In addition, the corner reinforcing bracket 9 used in this seismic structure includes a right-angle side plate 15 that abuts against the inner surfaces of the barrels 6 and 7 orthogonal to each other at each corner of the horizontal plane side frame A, and upper and lower end portions of the right-angle side plate 15. The pair of upper and lower triangular reinforcing plates 16 and 17 disposed horizontally, and the side plate extending portions 18 and 18 extending from the lower ends of the side plate portions 15a and 15a of the right side plate 15, respectively. 15 is fixed to the barrels 6 and 7 with bolts 42, one end of the horizontal plane bracing 10 is bolted to one of the upper and lower triangular reinforcing plates 16 and 17, and the wall side bracings 12 and 13 are connected to the side plate extension 18. Since the bolts 30 and 36 are fixed to one end, the structure is extremely robust, can sufficiently withstand a large external force, and is attached to the corner of the horizontal plane side frame A, the horizontal plane brace 10 is attached, And Mounting wall side braces 12 and 13 become respectively simple and easy, it is possible to improve the construction efficiency of seismic structures.

また、コーナー補強金具９には、上部三角形補強板１６の直角側板１５側端部に、先端部に釘孔２３を有し且つ互いに直交する胴差し６，７の上端面で支持される補強金具仮止め用突片２４を複数個取り付けているから、このコーナー補強金具９を水平面側骨組Ａの四隅部に取り付けるにあたり、補強金具仮止め用突片２４を胴差し６，７の夫々上端面に支持させ、各突片２４の釘孔２３より胴差し６，７に釘４１を打ち込んで、コーナー補強金具９を仮止めすることによって、胴差し６，７に対する直角側板１５のボルト４２止め作業を容易にして且つ安全に行うことができる。   Further, the corner reinforcing bracket 9 has a reinforcing bracket which is supported by the upper end surfaces of the body inserts 6 and 7 which have a nail hole 23 at the tip and are orthogonal to each other at the end of the upper triangular reinforcing plate 16 on the right side plate 15 side. Since a plurality of temporarily fixing protrusions 24 are attached, when attaching the corner reinforcing metal fittings 9 to the four corners of the horizontal plane side frame A, the reinforcing metal fitting temporary fixing protrusions 24 are respectively attached to the upper end surfaces of the barrels 6 and 7. The nail 41 is driven into the barrels 6 and 7 from the nail holes 23 of the projecting pieces 24 and the corner reinforcing metal fittings 9 are temporarily fixed, so that the bolt 42 of the right side plate 15 is fixed to the barrels 6 and 7. It can be done easily and safely.
