Description

この発明は、通し柱と床梁や胴差しなどの梁とを一体に連結する連結金具および連結金具を用いて通し柱と梁とを連結して構築される2階建てあるいは3階建て木造建築部、例えば、木造住宅の軸組構造体に関するものである。   This invention is a two-story or three-story wooden building part constructed by connecting a through column and a beam using a connecting bracket and a connecting bracket that integrally connect a through column and a beam such as a floor beam and a torso, For example, the present invention relates to a frame structure of a wooden house.

一般に、木造住宅の軸組構造体は、基礎にアンカーボルトを介して固定された土台に通し柱を立設し、通し柱にわたって2階の胴差しや床梁を架設するとともに、通し柱の上端にわたって小屋梁を架設して構成されている。また、3階建ての場合には、同様に、基礎にアンカーボルトを介して固定された土台に通し柱を立設するとともに、通し柱の上端に管柱を連結し、通し柱にわたって2階の胴差しや床梁および3階の胴差しや床梁を架設するとともに、3階の管柱の上端にわたって小屋梁を架設して構成されている。   In general, a frame structure of a wooden house has a through column installed on a foundation fixed to a foundation via anchor bolts, and a second floor torso and floor beam are installed over the through column, and a hut beam is installed over the upper end of the through column. Is constructed. In the case of a three-story building, similarly, a through column is erected on a base fixed to the foundation via anchor bolts, and a pipe column is connected to the upper end of the through column. It is constructed by laying floor beams and third-floor trunks and floor beams, and shed beams over the upper ends of the third-floor pipe columns.

このような軸組構造体においては、図12に示すように、通し柱Pに対して胴差しや床梁などの梁Gを連結する場合、梁Gの端面にほぞtを形成するとともに、通し柱Pに梁Gのほぞtに対応するほぞ穴mを形成し、通し柱Pのほぞ穴mに梁Gのほぞtを差し込んで連結するようにしている。このため、通し柱Pは、出隅部においては、隣接する2面にほぞ穴mが形成され、出隅部間の中間部では3面にほぞ穴mが形成され、中央部分では4面にほぞ穴mが形成される。したがって、通し柱Pは、断面積が減少した状態で垂直荷重を支持することになる。   In such a frame structure, as shown in FIG. 12, when connecting a beam G such as a trunk or a floor beam to the through column P, a tenon t is formed on the end face of the beam G, and the through column P A mortise m corresponding to the tenon t of the beam G is formed, and the tenon t of the beam G is inserted into the tenon hole m of the through column P to be connected. For this reason, the through-column P has mortises m formed in two adjacent surfaces at the projecting corners, mortises m formed in three surfaces in the middle portion between the projecting corners, and tenons on the four surfaces in the central portion. A hole m is formed. Therefore, the through column P supports the vertical load in a state where the cross-sectional area is reduced.

例えば、現在、1辺が12cmの角材を通し柱Pとして用いることが一般的であるが、この通し柱Pに図13(a)に示すほぞ穴mを2面に形成した場合、断面積は111.00cm2 となり、ほぞ穴mを形成しない場合の断面積144.00cm2 に比較して、断面積は、111/144≒77.1%に減少する。同様に、ほぞ穴mを3面に形成した場合(図13(b)参照)およびほぞ穴mを4面に形成した場合(図13(c)参照)は、それぞれ断面積は94.50cm2 、78.00cm2 となり、それぞれ94.5/144≒65.6%、78/144≒54.2%に減少する。 For example, at present, it is common to use a square member having a side of 12 cm as a through pillar P. When the ten-holes m shown in FIG. 00cm 2, and the compared to the cross-sectional area 144.00Cm 2 in the case of not forming the mortise m, the cross-sectional area decreases to 111/144 ≒ 77.1%. Similarly, when the mortise m is formed on three surfaces (see FIG. 13B) and when the mortise m is formed on four surfaces (see FIG. 13C), the cross-sectional area is 94.50 cm 2. 78.00 cm 2 , which are reduced to 94.5 / 144≈65.6% and 78 / 144≈54.2%, respectively.

したがって、木材、例えば、桧の場合、引張強度が6.77MPa、圧縮強度が5.30MPa、剪断強度が0.69MPaであることから、ほぞ穴mがない場合には、6.77MPa×144cm2 =97.49×103 Nの引張荷重に耐えることができるのに対し、ほぞ穴mが2面に形成された場合には、6.77MPa×111cm2 =75.15×103 N、ほぞ穴mが3面に形成された場合には、6.77MPa×94.5cm2 =63.98×103 N、ほぞ穴mが4面に形成された場合には、6.77MPa×78cm2 =52.81×103 Nにそれぞれ引張許容荷重が減少する。 Therefore, in the case of wood, for example, cocoons, the tensile strength is 6.77 MPa, the compressive strength is 5.30 MPa, and the shear strength is 0.69 MPa. Therefore, when there is no mortise m, 6.77 MPa × 144 cm 2 = 97.49 × 10 3 N can withstand a tensile load, but when mortise m is formed on two sides, 6.77 MPa × 111 cm 2 = 75.15 × 10 3 N, tenon When the hole m is formed on three surfaces, 6.77 MPa × 94.5 cm 2 = 63.98 × 10 3 N, and when the mortise m is formed on four surfaces, 6.77 MPa × 78 cm 2 Each of the allowable tensile loads decreases to 52.81 × 10 3 N.

同様に、桧の圧縮強度が5.30MPa、剪断強度が0.69MPaであることから、ほぞ穴mがない場合には、76.32×103 Nの圧縮荷重、9.94×103 Nの剪断荷重に耐えることができるのに対し、ほぞ穴mが2面に形成された場合には、58.83×103 Nの圧縮許容荷重および7.66×103 Nの剪断許容荷重に減少し、ほぞ穴mが3面に形成された場合には、50.09×103 Nの圧縮許容荷重および6.52×103 Nの剪断許容荷重に減少し、ほぞ穴mが4面に形成された場合には、41.34×103 Nの圧縮許容荷重および5.38×103 Nの剪断許容荷重に減少する。 Similarly, since the compressive strength of the ridge is 5.30 MPa and the shear strength is 0.69 MPa, when there is no mortise m, a compressive load of 76.32 × 10 3 N, 9.94 × 10 3 N In the case where the mortise m is formed on two surfaces, the compressive load of 58.83 × 10 3 N and the shear load of 7.66 × 10 3 N can be obtained. When the mortise m is formed on 3 sides, the mortise m is reduced to 50.09 × 10 3 N compression allowable load and 6.52 × 10 3 N shear allowable load. In this case, the compression allowable load is reduced to 41.34 × 10 3 N and the shear allowable load is 5.38 × 10 3 N.

この結果、地震などにより梁Gを介して大きな水平力が通し柱Pに作用すると、通し柱Pがほぞ穴m部分で破断し、家屋が倒壊することになる。   As a result, when a large horizontal force acts on the through column P via the beam G due to an earthquake or the like, the through column P breaks at the mortise m portion, and the house collapses.

このような強度減少に対応して、通し柱Pに羽子板ボルトRを貫通して固定するとともに、通し柱Pにほぞ接ぎされた梁Gに羽子板ボルトRを配置し、梁Gと羽子板ボルトRとをボルトおよびナットを介して連結したり(図14参照)、特許文献1に示すように、柱に断面コ字状の補強金具を固定する一方、梁に補強金具を差し込み可能な溝を形成し、梁の溝を補強金具に差し込んでボルトおよびナットもしくはドリフトピンを介して固定することが提案されている。
特開平11−310961号公報
Corresponding to such a decrease in strength, the wing plate bolt R is passed through and fixed to the through-column P, and the wing plate bolt R is arranged on the beam G tenoned to the through-column P, and the beam G and the wing plate bolt R are bolted together. And connecting via a nut (see FIG. 14), as shown in Patent Document 1, a U-shaped reinforcing bracket is fixed to a column, while a groove into which the reinforcing bracket can be inserted is formed in the beam. It has been proposed to insert the groove into a reinforcing bracket and fix it through a bolt and nut or a drift pin.
JP-A-11-310961

ところで、前述した羽子板ボルトを介して通し柱と梁とを連結する構造では、通し柱に対する梁の連結強度を向上させることができるものの、通し柱にほぞ穴を形成する点では同じであり、通し柱の断面積の減少による強度の減少を避けることはできない。このため、地震などによって大きな水平力が作用した場合に、通し柱の破断を防止することは困難である。   By the way, in the structure in which the through-column and the beam are connected via the above-described wing plate bolt, although the connection strength of the beam to the through-column can be improved, it is the same in that a mortise is formed in the through-column, and the cross-sectional area of the through-column is the same. It is inevitable that the strength will decrease due to the decrease in strength. For this reason, it is difficult to prevent the through column from being broken when a large horizontal force is applied due to an earthquake or the like.

また、特許文献1に示す補強金具では、通し柱にほぞ穴などの断面欠落がないため、通し柱の強度を確保することができる。しかしながら、通し柱の直交する2方向に梁を架設するため、柱の各面に補強金具を固定する場合、一面の補強金具を固定するボルトと他面の補強金具を固定するボルトとが干渉しないように、直交する2方向にそれぞれ複数個のボルト穴を形成する必要がある他、梁の端面にも補強金具を挿通するための溝を形成したり、補強金具に懸架するための金具を取り付けなければならず、前作業に多くの時間が必要になるとともに、煩雑な作業を必要とするという欠点がある。しかも、このような補強金具を別注して製作しなければならず、コストがかさむものとなる。   Moreover, in the reinforcement metal fitting shown in patent document 1, since there is no cross-sectional omission, such as a mortise, in the through pillar, the strength of the through pillar can be secured. However, since the beams are installed in two directions perpendicular to the through-column, when the reinforcing bracket is fixed to each surface of the column, the bolt that fixes the reinforcing bracket on one surface and the bolt that fixes the reinforcing bracket on the other surface do not interfere with each other. In addition, it is necessary to form a plurality of bolt holes in each of two orthogonal directions, and to form a groove for inserting the reinforcing bracket on the end face of the beam, or to attach a bracket for hanging on the reinforcing bracket. In addition, there are disadvantages that a lot of time is required for the previous work and a complicated work is required. In addition, such a reinforcing metal fitting must be manufactured separately, which increases the cost.

本発明は、このような問題点に鑑みてなされたもので、安価に製作することができるとともに、通し柱に断面欠落を発生させることなく通し柱と梁とを簡単に連結することができる連結金具を提供するものである。また、本発明は、連結金具を用いて通し柱と梁とを簡単に連結することができるとともに、工期を短縮して構築することができる木造建築物の軸組構造体を提供するものである。   The present invention has been made in view of such problems, and can be manufactured at a low cost, and a connecting bracket that can easily connect a through column and a beam without causing a cross-sectional defect in the through column. It is to provide. In addition, the present invention provides a frame structure of a wooden building that can easily connect a through column and a beam using a connecting fitting and can be constructed with a shortened construction period.

本発明の連結金具は、通し柱の外形形状に相当する内面形状に形成された設定長さの鋼製角筒と、角筒の隣接する2辺の各外面または3辺の各外面もしくは全ての辺の各外面に梁の幅に相当する内面間隔をおいてそれぞれ全周溶接された一対の鋼板製側板とからなり、角筒の対向する一対の辺に複数個のボルト穴が形成されるとともに、各一対の側板に複数個のボルト穴が形成されることを特徴とするものである。   The connecting bracket of the present invention includes a steel square tube having a set length formed in an inner surface shape corresponding to the outer shape of the through pillar, and two adjacent outer surfaces or three outer surfaces or all sides of the rectangular tube. A pair of steel plate side plates welded all around the inner surface corresponding to the width of the beam on each outer surface, and a plurality of bolt holes are formed on a pair of opposite sides of the square tube, A plurality of bolt holes are formed in each pair of side plates.

本発明によれば、角筒として市販品の軽角形鋼を、側板として市販品の鋼板をそれぞれ使用することができ、安価に製作することができるとともに、木材に比較して強度を大幅に向上させることが可能となる。しかも、角筒に通し柱を挿通し、ボルトおよびナットを介して簡単に固定することができるとともに、胴差しなどの梁を一対の側板間に落とし込み、ボルトおよびナットを介して簡単に固定することができ、熟練を要することなく短時間に連結作業を行うことができる。   According to the present invention, it is possible to use a commercially available light square steel as a square tube and a commercially available steel plate as a side plate, respectively, which can be manufactured at low cost and greatly improved in strength compared to wood. It becomes possible to make it. Moreover, it is possible to insert a through column into a square tube and easily fix it via bolts and nuts, and to drop a beam such as a torso between a pair of side plates and easily fix it via bolts and nuts. The connection work can be performed in a short time without skill.

本発明において、前記角筒が通し柱に連結される管柱の下端部を挿通可能な長さを有すると、角筒に管柱の下端部を挿通してボルトおよびナットを介して簡単に連結することができるとともに、通し柱と管柱の連結部分の強度を大幅に向上させることができる。   In the present invention, when the square tube has a length that allows the lower end portion of the tube column connected to the through column to be inserted, the lower end portion of the tube column is inserted into the square tube and is easily connected via a bolt and a nut. In addition, the strength of the connecting portion between the through column and the tube column can be greatly improved.

本発明の木造建築物の軸組構造体は、土台に立設されて1階から2階までを貫く長さの複数本の通し柱と、これらの通し柱にわたって架設される複数本の2階の梁と、通し柱の上端にわたって架設される複数本の小屋梁と、からなり、通し柱の略中間部に請求項1記載の連結金具の角筒が挿通されてボルトおよびナットを介して固定され、その各一対の側板に2階の各梁が挟み込まれてボルトおよびナットを介して固定されることを特徴とするものである。   A frame structure of a wooden building according to the present invention includes a plurality of through pillars that are erected on a base and extend from the first floor to the second floor, and a plurality of second-floor beams that are installed across the through pillars. And a plurality of shed beams laid over the upper end of the through pillar, and the square tube of the connecting metal fitting according to claim 1 is inserted in a substantially middle portion of the through pillar and fixed through bolts and nuts, Each beam on the second floor is sandwiched between a pair of side plates and fixed through bolts and nuts.

After dropping, the pair of side plates and the beam are fixed via bolts and nuts. Next, a frame structure of a two-story wooden building is constructed by installing a shed beam between the upper ends of the through pillars.

この結果、角筒に側板が溶着されて一体化された連結金具を通し柱の略中間部に固定することにより、2階の梁との連結位置となる通し柱の略中間部の周囲が角筒によって包囲され、通し柱を補強してその破断を防止することができるとともに、通し柱に対する梁の連結強度を向上させることができる。また、建築現場において、ボルト穴が形成された通し柱およびボルト穴が形成された梁をそれぞれ配置し、ボルトを挿通してナットを締結するだけの簡単な作業で2階建て木造建築物の軸組構造体を構築することができるとともに、工期を短縮することができる。   As a result, by fixing the connecting metal fitting in which the side plate is welded to the square tube and fixing it to the substantially middle part of the through column, the square tube surrounds the substantially middle part of the through column which becomes the connection position with the beam on the second floor. While being surrounded, the through pillar can be reinforced to prevent its breakage, and the connection strength of the beam to the through pillar can be improved. In addition, in a construction site, a through-column with bolt holes and a beam with bolt holes are arranged, and a framework of a two-story wooden building is simply constructed by inserting bolts and fastening nuts.

And a third floor beam, a plurality of pipe columns erected on the upper end of the through pillar, and a plurality of shed beams erected across the upper end of the pipe pillar.

After dropping so as to be sandwiched between the pair of side plates of the coupling metal fixed to the intermediate portion, the pair of side plates and the beam are fixed via bolts and nuts. Next, after lifting the beam on the third floor and dropping it so as to be sandwiched between the pair of side plates of the connecting metal fitting fixed to the upper end of the through column, the pair of side plates and the beam are fixed via bolts and nuts.

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

図1乃至図3には、本発明の連結金具1の一実施形態が示されている。   1 to 3 show an embodiment of the connection fitting 1 of the present invention.

この連結金具1は、設定長さの鋼製角筒2と、角筒2の隣接する3辺の各外面に設定された内面間隔をおいてそれぞれ全周溶接された一対の鋼板製側板3,3と、から構成されている。   This connecting metal fitting 1 includes a steel square tube 2 having a set length, and a pair of steel plate side plates 3 that are welded all around the inner surface with a space between inner surfaces set on the outer surfaces of three adjacent sides of the square tube 2. 3.

角筒2は、1辺が120mm角の通し柱Pの外面形状に対応する内面形状を有する設定長さの軽角形鋼から形成され、図3において、左右方向に対向する2辺には、上下方向に間隔をおいて同一軸線上に位置する複数個のボルト穴2a(図1参照)、具体的には、3個のボルト穴2aがそれぞれ形成されている。   The square tube 2 is formed from a light-angle steel with a set length having an inner surface shape corresponding to the outer surface shape of a through pillar P having a side of 120 mm square, and in FIG. A plurality of bolt holes 2a (see FIG. 1), specifically three bolt holes 2a, which are positioned on the same axis with a space therebetween are formed.

一対の側板3,3は、鋼板からなり、各上端縁が角筒2の上端縁と面一に連続するように、かつ、胴差しGの幅に対応する内面間隔をおいて角筒2の3辺の各外面にそれぞれ溶接されている。そして、各一対の側板3には、上下方向および左右方向に設定間隔をおいて同一軸線上に位置する複数個のボルト穴3aが形成されている。例えば、図3において、角筒2の右辺にそれぞれ一側端縁が溶着されて右方向に延びる各側板3は、幅120mm×高さ240mmの胴差しGに対応するように、120mmの内面間隔をおいて配設されており、左右方向および上下方向にそれぞれ設定間隔をおいて2個ずつ計4個のボルト穴3aが形成されている。また、図3において、角筒2の上辺および下辺にそれぞれ一側端縁が溶着されて上方向および下方向に延びるた各側板3は、幅105mm×高さ180mmの胴差しGに対応するように、105mmの内面間隔をおいて配設されており、左右方向および上下方向にそれぞれ設定間隔をおいて2個ずつ計4個のボルト穴3aが形成されている。   The pair of side plates 3 and 3 are made of a steel plate, and the upper end edges of the square tube 2 are arranged so as to be flush with the upper end edge of the square tube 2 and at an inner surface interval corresponding to the width of the body G. It is welded to each of the three outer surfaces. Each pair of side plates 3 is formed with a plurality of bolt holes 3a positioned on the same axis at set intervals in the vertical direction and the horizontal direction. For example, in FIG. 3, each side plate 3 whose one side edge is welded to the right side of the square tube 2 and extends in the right direction has an inner surface interval of 120 mm so as to correspond to the body insertion G having a width of 120 mm × a height of 240 mm. A total of four bolt holes 3a are formed, two each at set intervals in the left-right direction and the up-down direction. Further, in FIG. 3, each side plate 3 having one side edge welded to the upper side and the lower side of the square tube 2 and extending upward and downward corresponds to the body G having a width of 105 mm and a height of 180 mm. In addition, a total of four bolt holes 3a are formed, two at a set interval in the left-right direction and the up-down direction.

このように、連結金具1は、軽角形鋼からなる角筒2と、角筒2の3辺にそれぞれ溶着された一対の鋼板製側板3と、から構成されることにより、いずれも市販品を利用することができ、安価に製作することができる。しかも、鋼製であるため、強度を大幅に向上させることが可能となる。   Thus, the connecting metal fitting 1 is composed of the square tube 2 made of light square steel and the pair of steel plate side plates 3 welded to the three sides of the square tube 2, respectively. It can be used and can be manufactured at low cost. Moreover, since it is made of steel, the strength can be greatly improved.

ちなみに、120mm角の通し柱Pに対応する125mm×125mm×厚み3.2mmの角筒2の場合、断面積が15.33cm2 となるとともに、引張強度および圧縮強度とも156.91MPaであり、剪断強度が90.61MPaであることから、156.91MPa×15.33cm2 =240.54×103 Nの引張荷重および圧縮荷重に耐えることができるとともに、90.61MPa×15.33cm2 /2=69.45×103 Nの剪断荷重に耐えることができ、木材をほぞ接ぎする場合に比較して強度を大幅に向上させることができる。 Incidentally, in the case of the square tube 2 of 125 mm × 125 mm × 3.2 mm thickness corresponding to the 120 mm square through-pillar P, the cross-sectional area is 15.33 cm 2, and both the tensile strength and the compressive strength are 156.91 MPa, and the shear strength since There is 90.61MPa, it is possible to withstand the tensile load and compression load 156.91MPa × 15.33cm 2 = 240.54 × 10 3 N, 90.61MPa × 15.33cm 2/2 = 69 It can withstand a shear load of .45 × 10 3 N, and the strength can be greatly improved as compared with the case where timbers are tenoned together.

なお、前述した実施形態においては、出隅部間の中間部に立設される通し柱Pの3辺に胴差しGを連結する場合の連結金具1を例示したが、出隅部に立設される通し柱Pの隣接する2辺に2階の胴差しGを連結する場合の連結金具1は、図4に示すように、角筒2の隣接する2辺にそれぞれ一対の側板3が溶接されたものである。   In addition, in embodiment mentioned above, although the connection metal fitting 1 in the case of connecting the body insertion G to the three sides of the through pillar P standingly arranged in the intermediate part between the protruding corner parts was illustrated, it is erected on the protruding corner part. As shown in FIG. 4, the connecting fitting 1 in the case of connecting the second-floor body G to two adjacent sides of the through pillar P has a pair of side plates 3 welded to the two adjacent sides of the square tube 2. Is.

この連結金具1の角筒2も、通し柱Pの外面形状に対応する内面形状を有し、また、各一対の側板3の内面間隔も、胴差しGの幅に対応して設定されている。   The square tube 2 of the connection fitting 1 also has an inner surface shape corresponding to the outer surface shape of the through column P, and the inner surface distance between each pair of side plates 3 is also set corresponding to the width of the body G.

ところで、図5には、本発明の連結金具の他の実施形態が示されている。   By the way, FIG. 5 shows another embodiment of the connecting metal fitting of the present invention.

この実施形態の連結金具4は、3階建ての木造住宅において、3階の床を形成する胴差しGを通し柱Pの3辺に連結するとともに、通し柱Pに管柱P’を連結する場合に使用される。すなわち、3階建ての木造住宅においては、通常、1階から2階までを貫く長さの通し柱Pの上端に管柱P’の下端をほぞ接ぎして使用される。このため、連結金具4における角筒5の長さは、図1に示した連結金具1の角筒2の上端に、管柱P’の下端部を支持するに十分な長さを加えた長さに設定されている。そして、連結金具4の角筒5には、その下半部に挿通された通し柱Pの上端部および上半部に挿通された管柱P’の下端部をそれぞれ複数本のボルトナットによって固定できるように、複数個のボルト穴5a、具体的には、上半部および下半部にそれぞれ2個ずつの計4個のボルト穴5aが設定間隔をおいて形成されている。   The connecting bracket 4 of this embodiment is used in a three-story wooden house to connect the body G forming the floor of the third floor to the three sides of the through pillar P and to connect the pipe pillar P ′ to the through pillar P. used. That is, in a three-story wooden house, usually, the lower end of the pipe pillar P 'is used on the upper end of the through pillar P having a length extending from the first floor to the second floor. For this reason, the length of the square tube 5 in the connection fitting 4 is a length obtained by adding a length sufficient to support the lower end portion of the tube column P ′ to the upper end of the square tube 2 of the connection fitting 1 shown in FIG. Is set. And in the square tube 5 of the connection metal fitting 4, the upper end part of the through pillar P inserted in the lower half part and the lower end part of the pipe pillar P 'inserted in the upper half part can be fixed by a plurality of bolt nuts, respectively. As described above, a plurality of bolt holes 5a, specifically, four bolt holes 5a, two each in the upper half and the lower half, are formed at set intervals.

なお、胴差しGを連結するための一対の側板3については、図1に示した側板3と相違しないため、同一の符号を付して詳細な説明を省略する。   Note that the pair of side plates 3 for connecting the body insert G is not different from the side plate 3 shown in FIG.

この実施形態の連結金具4の変形例として、例えば、出隅部に立設される通し柱Pの隣接する2辺に3階の胴差しGを連結する場合の連結金具1を図6に示す。この連部金具4においても、角筒4の長さは、図4に示した連結金具1の角筒2の上端に,管柱P’の下端部を支持するに足る長さを加えた長さに設定されている。   As a modification of the connection fitting 4 of this embodiment, for example, FIG. 6 shows a connection fitting 1 in the case of connecting a third-floor trunk G to two adjacent sides of a through column P standing upright at a protruding corner. Also in this continuous metal fitting 4, the length of the square tube 4 is a length obtained by adding a length sufficient to support the lower end portion of the tube column P ′ to the upper end of the square tube 2 of the connection metal fitting 1 shown in FIG. 4.

なお、前述した実施形態においては、角筒2,4の隣接する2辺または3辺にそれぞれ一対の側板3を溶着する場合を例示したが、詳細には図示しないが、角筒2,4の4辺全てに一対の側板3を溶着した連結金具1,4であってもよいことはもちろんである。   In the above-described embodiment, the case where the pair of side plates 3 are welded to the adjacent two or three sides of the rectangular tubes 2 and 4 is illustrated, but although not illustrated in detail, Of course, the connecting fittings 1 and 4 in which a pair of side plates 3 are welded to all four sides may be used.

次に、このように構成された連結金具1を用いて3階建て木造住宅の軸組構造体を構築する場合について図7に基づいて説明する。   Next, the case where the frame structure of a three-story wooden house is constructed | assembled using the connection metal fitting 1 comprised in this way is demonstrated based on FIG.

まず、建築現場において、基礎Fを形成した後、基礎Fに土台Sを載置してアンカーボルト(図示せず)を介して固定する。この際、基礎Fには、後述するように、通し柱Pを立設する位置に合わせて補強金具6を構成するアンカーボルト62が埋設されており、その上端部が土台Sを貫通して上方に導出されている。   First, at the construction site, after the foundation F is formed, the base S is placed on the foundation F and fixed through anchor bolts (not shown). At this time, as will be described later, anchor bolts 62 constituting the reinforcing metal fitting 6 are embedded in the foundation F in accordance with the position where the through pillar P is erected, and the upper end of the anchor bolt 62 penetrates the base S and extends upward. Has been derived.

一方、工場などの建築現場以外の場所において、通し柱Pの下端部には、補強金具6を構成する引き寄せ金物61に形成されたボルト穴61aに対応して複数個のボルト穴Paが形成されるとともに、略中間部、具体的には、2階の胴差しGの天端面に対応する位置に連結金具1の上端縁が位置するように、その角筒2に形成されたボルト穴2aに対応して複数個のボルト穴Paが形成される。また、必要ならば、通し柱Pの上端部にも、3階の胴差しGの天端面に対応する位置に連結金具4の側板3の上端縁が位置するように、その角筒5に形成されたボルト穴5aのうち、下半部に形成された複数個のボルト穴5aに対応して複数個のボルト穴Paが形成される。その際、通し柱Pの上端にはほぞ穴mが合わせて形成され、後述するように、管柱P’の下端に形成されるほぞtとほぞ接ぎされるように設定されている(図10参照)。同様に、通し柱Pの下端にはほぞ(図示せず)が形成され、通し柱Pの立設位置に合わせて土台Sに形成されたほぞ穴とほぞ接ぎされるように設定されている。   On the other hand, in a place other than the construction site such as a factory, a plurality of bolt holes Pa are formed at the lower end portion of the through pillar P corresponding to the bolt holes 61a formed in the drawing metal 61 constituting the reinforcing bracket 6. In addition, it corresponds to the bolt hole 2a formed in the square tube 2 so that the upper end edge of the connecting metal fitting 1 is positioned at a position substantially corresponding to the top end surface of the second-stage trunk G on the second floor. Thus, a plurality of bolt holes Pa are formed. Further, if necessary, the square cylinder 5 is also formed at the upper end portion of the through pillar P so that the upper end edge of the side plate 3 of the connection fitting 4 is located at a position corresponding to the top end face of the third-floor trunk G. Among the bolt holes 5a, a plurality of bolt holes Pa are formed corresponding to the plurality of bolt holes 5a formed in the lower half. At that time, a mortise m is formed at the upper end of the through pillar P, and is set so as to be in contact with the mortise t formed at the lower end of the pipe pillar P ′ (see FIG. 10). ). Similarly, a tenon (not shown) is formed at the lower end of the through pillar P, and is set so as to be in contact with the tenon formed in the base S in accordance with the standing position of the through pillar P.

一方、管柱P’の下端には、通し柱Pのほぞ穴mに対応してほぞtが形成される他、その下端部には、連結金具4の角筒5に形成されたボルト穴5aのうち、上半部に形成された複数個のボルト穴5aに対応して複数個のボルト穴P’aが形成される。すなわち、通し柱Pの上端部に連結金具4がボルト7およびナット8を介して固定された状態で、該連結金具4の角筒5に管柱P’を挿通してそのほぞtを通し柱Pのほぞ穴mに差し込んでほぞ接ぎした際、連結金具4における角筒5のボルト穴5aが、管柱P’のボルト穴P’aとが合致するように、ボルト穴P’aが形成される。   On the other hand, a mortise t is formed at the lower end of the tube pillar P ′ corresponding to the mortise hole m of the through pillar P, and a bolt hole 5a formed in the square tube 5 of the connecting fitting 4 is formed at the lower end portion thereof. Among them, a plurality of bolt holes P′a are formed corresponding to the plurality of bolt holes 5 a formed in the upper half. That is, in a state where the connecting fitting 4 is fixed to the upper end portion of the through pillar P via the bolt 7 and the nut 8, the tube pillar P ′ is inserted into the rectangular tube 5 of the connecting fitting 4 and the tenon t is passed through the tenon t. The bolt hole P′a is formed so that the bolt hole 5a of the square tube 5 in the connecting metal fitting 4 matches the bolt hole P′a of the tube column P ′ when the mortise is inserted into the mortise m. .

さらに、胴差しGの両端部には、連結金具1,4の一対の側板3に形成されたボルト穴3aに対応して複数個のボルト穴がGaが形成される。   Furthermore, a plurality of bolt holes Ga are formed at both ends of the barrel G corresponding to the bolt holes 3 a formed in the pair of side plates 3 of the connecting fittings 1, 4.

この後、通し柱Pの略中間部まで連結金具1を強制的に打ち込んで挿通した後、連結金具1における角筒2の一辺に形成された各ボルト穴2a、通し柱Pの略中間部に形成された各ボルト穴Paおよび該角筒2の対向する他辺に形成された各ボルト穴2aにわたってボルト7をそれぞれ挿通した後、各ボルト7にそれぞれナット8を締結し、通し柱Pに連結金具1を固定する。この際、通し柱Pの立設位置に合わせて必要な連結金具1を選択するとともに、その取付位置および側板3の向きを合わせる。   Thereafter, the connecting fitting 1 is forcibly driven into and inserted through a substantially middle portion of the through pillar P, and then is formed in each bolt hole 2a formed on one side of the rectangular tube 2 in the connecting fitting 1 and in a substantially middle portion of the through pillar P. After the bolts 7 are inserted through the bolt holes Pa and the bolt holes 2a formed on the opposite sides of the square tube 2, the nuts 8 are fastened to the bolts 7, and the connecting fitting 1 is attached to the through pillar P. Fix it. At this time, the necessary connecting fitting 1 is selected in accordance with the standing position of the through pillar P, and the mounting position and the direction of the side plate 3 are matched.

同様に、管柱P’が接合される通し柱Pの上端部に連結金具4を強制的に打ち込んで挿通した後、連結金具4における角筒5の下半部に形成された各ボルト穴5aおよび通し柱Pの上端部に形成された各ボルト穴Paにわたってボルト7をそれぞれ挿通した後、各ボルト7にそれぞれナット8を締結し、通し柱Pに連結金具4を固定する。   Similarly, after the connecting bracket 4 is forcibly driven into and inserted through the upper end portion of the through column P to which the tube column P ′ is joined, each bolt hole 5a formed in the lower half of the rectangular tube 5 in the connecting bracket 4 and After the bolts 7 are inserted through the respective bolt holes Pa formed in the upper end portion of the through pillar P, nuts 8 are fastened to the respective bolts 7, and the connection fitting 4 is fixed to the through pillar P.

このような準備作業が終了したならば、連結金具1および連結金具1,4が固定された通し柱P、胴差しGを建築現場に輸送した後、各通し柱Pを対応する位置の土台Sのほぞ穴に下端のほぞを差し込んで立設する。次いで、図11に示すように、補強金具6を構成する引き寄せ金物61を予め土台Sから導出されたアンカーボルト62に挿通して土台S上に配置するとともに、引き寄せ金物61を通し柱Pの下端部の一面に添わせる。次いで、アンカーボルト62にナット8を締結して引き寄せ金物61を土台Sに固定した後、引き寄せ金物61の各ボルト穴61aおよび通し柱Pの下端部に形成された各ボルト穴Paにボルト7をそれぞれ挿通し、各ボルト7にナット8をそれぞれ締結して固定する。   When such a preparatory work is completed, after transporting the through pillar P and the torso G to which the connecting fitting 1 and the connecting fittings 1 and 4 are fixed to the construction site, the tenons of the base S at the corresponding positions of the through pillars P Insert the bottom tenon into the hole and stand upright. Next, as shown in FIG. 11, the drawing metal 61 constituting the reinforcing metal fitting 6 is inserted into the anchor bolt 62 previously derived from the base S and arranged on the base S, and the lower end of the column P is passed through the drawing metal 61. Attaching to one side. Next, the nut 8 is fastened to the anchor bolt 62 to fix the attracting metal 61 to the base S, and then the bolt 7 is respectively inserted into each bolt hole 61a of the attracting metal 61 and each bolt hole Pa formed at the lower end of the through pillar P. The nuts 8 are fastened and fixed to the bolts 7 respectively.

通し柱Pを立設すれば、クレーンなどを利用して2階の各胴差しGを対応する通し柱P,P間に吊り上げた後、胴差しGの両端部を通し柱Pの略中間部に固定された対向する連結金具1の一対の側板3,3間に落とし込む。そして、一方の側板3の各ボルト穴3a、胴差しGの一端部に形成された各ボルト穴Ga、他方の側板3の各ボルト穴3aにわたってボルト7をそれぞれ挿通した後、各ボルト7にナット8をそれぞれ締結する。対向する他方の連結金具1の側板3,3についても、同様に、一方の側板3の各ボルト穴3a、胴差しGの他端部の各ボルト穴Ga、他方の側板3の各ボルト穴3aにわたってボルト7をそれぞれ挿通した後、各ボルト7にナット8をそれぞれ締結する。   If the through pillars P are erected, each of the second-floor torso G is lifted between the corresponding through-pillars P and P using a crane or the like, and then both ends of the torso G are fixed to substantially the middle part of the through-pillar P. It is dropped between the pair of side plates 3 and 3 of the connecting metal fitting 1 facing each other. And after inserting bolt 7 over each bolt hole 3a of one side plate 3, each bolt hole Ga formed in one end part of body insertion G, and each bolt hole 3a of the other side plate 3, it is nut to each bolt 7 8 is concluded. Similarly, for the side plates 3 and 3 of the other coupling metal 1 facing each other, each bolt hole 3a of one side plate 3, each bolt hole Ga of the other end of the body insertion G, and each bolt hole 3a of the other side plate 3 After the bolts 7 are inserted, the nuts 8 are fastened to the bolts 7 respectively.

以下、同様に、2階の胴差しGを順に吊り上げて、対応する一対の通し柱P,P間において、連結金具1,1にボルト7およびナット8を介して固定する。   In the same manner, similarly, the second-floor torso G is lifted in order, and is fixed to the connecting fittings 1 and 1 via bolts 7 and nuts 8 between a pair of corresponding through pillars P and P.

通し柱Pに対して2階の胴差しGの固定が終了すれば、同様に、クレーンなどを利用して3階の各胴差しGを対応する通し柱P,P間に吊り上げた後、胴差しGの両端部を通し柱Pの上端部に固定された対向する連結金具4の一対の側板3,3間に落とし込み、各一対の側板3,3と胴差しGの各端部とをボルト7およびナット8を介して固定する。   When the fixation of the second-floor torso G with respect to the through pillar P is completed, similarly, the third-floor torso G is lifted between the corresponding through-pillars P and P using a crane or the like, and then the torso G Are dropped between a pair of side plates 3 and 3 of the opposing connecting metal fitting 4 fixed to the upper end of the column P, and the bolts 7 and nuts are connected between the pair of side plates 3 and 3 and the ends of the body G. 8 to fix.

通し柱Pに対して2階の胴差しGおよび3階の胴差しGを順に固定したならば、通し柱Pの上端部に固定された連結金具4の角筒5に対応する各管柱P’を挿通し、通し柱Pの上端に形成されたほぞ穴mに管柱P’のほぞtを差し込んでほぞ接ぎする。次いで、連結金具4の角筒5の一辺側の各ボルト穴5a、管柱P’の各ボルト穴P’a、角筒5の他辺側の各ボルト穴5aにわたってボルト7をそれぞれ挿通した後、各ボルト7にナット8をそれぞれ締結し、管柱P’を連結金具4に固定する。   If the second-floor case G and the third-floor case G are fixed in order to the through column P, each tube column P ′ corresponding to the square tube 5 of the connecting fitting 4 fixed to the upper end of the through column P is attached. The tenon t of the tube column P ′ is inserted into the tenon hole m formed at the upper end of the through column P, and is connected to the tenon. Next, after the bolts 7 are inserted through the bolt holes 5a on one side of the square tube 5 of the connecting fitting 4, the bolt holes P'a on the tube pillar P ', and the bolt holes 5a on the other side of the square tube 5, respectively. The nut 8 is fastened to each bolt 7, and the tube pillar P ′ is fixed to the connection fitting 4.

管柱P’を固定したならば、対向する管柱P’,P’の上端部間にわたって対応する小屋梁G’を架け渡した後、小屋梁G’を利用して小屋組みを形成すればよい。   If the pipe column P ′ is fixed, the corresponding shed beam G ′ is bridged over the upper end portions of the opposite tube columns P ′ and P ′, and then the shed assembly is formed using the shed beam G ′. .

この結果、予めボルト穴Paを形成するとともに、連結金具1,4を固定した通し柱Pおよびボルト穴Gaを形成した胴差しGを建築現場に持ち込み、土台Sに通し柱Pを立設した後、胴差しGを通し柱Pに固定した連結金具1,4にボルト7およびナット8を介して順に連結することによって木造住宅の軸組構造体を構築することができることから、作業が簡単になり、熟練を要することなく簡単に作業することができるとともに、短納期で施工することができる。しかも、通し柱Pに欠落部分がないため、通し柱Pの強度低下が発生することがない上に、連結金具1,4によって補強されるため、強度を大幅に向上させることができ、大きな地震などによっても通し柱Pの破断に伴う家屋の倒壊を確実に防止することができる。   As a result, the bolt hole Pa is formed in advance, and the through column P in which the connecting metal fittings 1 and 4 are fixed and the torso G in which the bolt hole Ga is formed are brought to the construction site, and the through column P is erected on the base S. Since the frame structure of the wooden house can be constructed by sequentially connecting the connecting fittings 1 and 4 fixed to the pillar P through the insert G via the bolts 7 and the nuts 8, the work is simplified and the skill is improved. It can be easily done without needing, and can be constructed with a short delivery time. In addition, since there is no missing portion in the through pillar P, the strength of the through pillar P is not reduced, and it is reinforced by the connecting metal fittings 1 and 4, so that the strength can be greatly improved. In addition, the collapse of the house due to the breakage of the through pillar P can be reliably prevented.

この場合、大きな地震などによって縦揺れした場合、通し柱Pが土台Sから引き抜かれるおそれがあるが、基礎Fに固定された補強金具6と通し柱Pがボルト7およびナット8を介して固定されることにより、通し柱Pの引き抜きにも十分に抗することができる。   In this case, there is a possibility that the through pillar P is pulled out from the base S when it is pitched by a large earthquake or the like. However, the reinforcing bracket 6 fixed to the foundation F and the through pillar P are fixed through the bolt 7 and the nut 8. Thus, it is possible to sufficiently resist the pulling of the through pillar P.

なお、前述した実施形態においては、3階建て木造住宅の軸組構造体を例示したが、2階建て木造住宅においても適用できることはいうまでもない。この場合は、略中間部のみに連結金具1を固定した通し柱Pを用いればよい他、その上端部に小屋梁を架設すればよい。   In the above-described embodiment, the frame structure of a three-story wooden house is exemplified, but it goes without saying that the present invention can also be applied to a two-story wooden house. In this case, it is only necessary to use the through pillar P in which the connecting metal fitting 1 is fixed only in the substantially middle portion, and a shed beam may be installed on the upper end portion.

以上のように本発明によれば、地震などによって大きな水平力が通し柱に作用したとしても、その破断を防止することができることから、家屋などの建築物の耐震性を向上させることができる。   As described above, according to the present invention, even if a large horizontal force is applied to the through column due to an earthquake or the like, the breakage can be prevented, so that the earthquake resistance of a building such as a house can be improved.
