The extended support plate 32 and the guide plate 33 that rises from the support plate 32 and extends along the base plate 31 intersect with each other in an orthogonal direction to form a cast product.

梁受け金物30は、サポートプレート32の中央部前側から立上がるロケットピンとしてのガイドピン34がガイドプレート33の両側面に沿って固着される。梁受け金物30のガイドプレート33には、後述するドリフトピン35を挿通させる通し孔36が複数形成されており、ベースプレート31にも複数の通し孔の開口37が形成される。梁受け金物30は、構造用鉄骨柱12の建物各階の側面に溶接にて固定される例を例示するが、梁受け金物30はベースプレート31の開口37を利用してボルト等で構造用鉄骨柱12の側面に固定させてもよい。   A guide pin 34 as a rocket pin rising from the front side of the center portion of the support plate 32 is fixed along the both side surfaces of the guide plate 33. A plurality of through holes 36 through which drift pins 35 (described later) are inserted are formed in the guide plate 33 of the beam receiver 30, and a plurality of through holes openings 37 are also formed in the base plate 31. The beam receiving metal 30 is exemplified by an example of being fixed to the side surface of each floor of the building of the structural steel column 12 by welding. However, the beam receiving metal 30 is structured with a bolt or the like using the opening 37 of the base plate 31. You may fix to 12 side surfaces.

さらに、木造建築物10では、図1に示すように、対向する構造用鉄骨柱12,12間に木製構造梁であるメイン梁40が横架される。メイン梁40は、桧ムク材や大断面の木材の構造用集成材、または不燃材と木材の複合材等で構成される。構造用集成材は、桧、杉、米松、唐松等の樹種材(天然木材)のひき板を、含水率15%以下まで乾燥させ、複数枚(3枚以上)のひき板をエポキシ樹脂等の接着材を用いて重ね合せ、接着したものである。メイン梁40は、梁幅(W)×梁高さ(H)が、例えば、大断面の構造用集成材が用いられる。構造用集成材は、幅寸法(W)×高さ寸法(H)が105mm(〜240mm)×240mm(〜600mm)で、W<Hの寸法関係を保って製作される。梁幅(W)×梁高さ(H)が、例えば、120mm×300mm,120mm×380mm,120mm×450mm(あるいは105mm×300mm,105mm×380mm,105mm×450mm)の大断面のメイン梁40が用いられる。メイン梁40の両側に、防火対策として1時間耐火用では、板厚45mmの集成材または板厚60mmの無垢材の耐防火被覆材(図示省略)が接着され、設けられる。   Furthermore, in the wooden building 10, as shown in FIG. 1, a main beam 40, which is a wooden structural beam, is horizontally mounted between the structural steel columns 12 and 12 facing each other. The main beam 40 is composed of a firewood material, a structural laminated material of wood having a large cross section, or a composite material of non-combustible material and wood. For structural laminated timber, dry wood (natural wood) such as firewood, cedar, rice pine, karamatsu, etc., and dry it to a moisture content of 15% or less. It is the one that is overlapped and bonded using an adhesive. For the main beam 40, a structural laminated material having a beam width (W) × beam height (H) having a large cross section, for example, is used. The structural laminated material has a width dimension (W) × height dimension (H) of 105 mm (˜240 mm) × 240 mm (˜600 mm), and is manufactured while maintaining a dimensional relationship of W <H. For example, a main beam 40 having a large cross section with a beam width (W) × beam height (H) of 120 mm × 300 mm, 120 mm × 380 mm, 120 mm × 450 mm (or 105 mm × 300 mm, 105 mm × 380 mm, 105 mm × 450 mm) is used. It is done. A fireproof covering material (not shown) made of a laminated material having a plate thickness of 45 mm or a solid material having a plate thickness of 60 mm is provided on both sides of the main beam 40 for fireproofing for 1 hour.

メイン梁40は構造梁としてのラーメン梁であり、メイン梁40が大断面の構造用集成材あるいは複合材を用いると、万一の火災時に集成材あるいは複合材は表面が焦げると、焦げた表面に炭化層ができ、この炭化層が酸素の供給を遮断し、それ以上の燃焼を食い止める役目を果す。メイン梁40は表面が焦げるだけなので、構造材としての強度を保つことができ、建物の崩壊を遅延させ、防ぐことができる。   The main beam 40 is a ramen beam as a structural beam. If the main beam 40 is made of structural laminated material or composite material having a large cross section, the surface of the laminated material or composite material will be burnt in the event of a fire. A carbonized layer is formed, and this carbonized layer serves to cut off the supply of oxygen and stop further combustion. Since the surface of the main beam 40 is only burned, the strength as a structural material can be maintained, and the collapse of the building can be delayed and prevented.

図1に示される木造3階建ての建物では、例えば建物1階のメイン梁40に120mm×450mm断面の構造用集成材が用いられ、建物2階および建物3階には120mm×390mm,120mm×300mm断面の構造用集成材が用いられる。3階建ての建物では、建物1階のメイン梁40から上層階に向うに従って、メイン梁40の梁高さ(H)が漸次低くなるように構成される。建物各階のメイン梁40には、例えば大断面の構造用集成材がラーメン梁として用いられる。   In the wooden three-story building shown in FIG. 1, for example, the main beam 40 on the first floor of the building uses a 120 mm × 450 mm cross-section structural laminate, and the second and third floors of the building are 120 mm × 390 mm, 120 mm × A structural laminate with a 300 mm cross section is used. The three-story building is configured such that the beam height (H) of the main beam 40 gradually decreases from the main beam 40 on the first floor of the building toward the upper floor. For the main beam 40 on each floor of the building, for example, a structural laminated material having a large cross section is used as a ramen beam.

メイン梁40に用いられる木製の構造用集成材は、天然のムク材より高い剛性強度を有し、内部は常に乾燥した状態に保たれるため、水分や湿度の影響を受けにくく、反りや歪み、割れの殆ど無い、安定した品質の構造梁が長期に亘り保持される。   The wooden structural laminated material used for the main beam 40 has higher rigidity and strength than natural mukwood, and the interior is always kept dry, so it is less susceptible to moisture and humidity, and warps and distortions. Stable quality structural beams with little cracking are retained for a long time.

天然木材の構造用集成材で構成されたメイン梁40は、図1,図2および図6ないし図8に示すように、ラーメン梁の構造梁を構成している。メイン梁40の構造梁は、梁長さが3600mmあるいは5400mmのラーメン梁が標準使用材として用いられる。   As shown in FIGS. 1, 2, and 6 to 8, the main beam 40 made of structural lumber made of natural wood constitutes a structural beam of a ramen beam. As the structural beam of the main beam 40, a rigid beam having a beam length of 3600 mm or 5400 mm is used as a standard material.

メイン梁40構造用鉄骨柱12(12a,12b,12c)の接合構造は、図7(A),(B)および(C)に示すように組み付けられる。 The joint structure of the main beam 40 and the structural steel column 12 (12a, 12b, 12c) is assembled as shown in FIGS. 7 (A), (B) and (C).

初めに、構造用鉄骨柱12(12a,12b,12c)の建物各階上部側面に、梁受け金物30が溶接等の締着手段で、図7(A)に示すように固定される。実際には、梁受け金物30を固定した鉄骨柱エレメント12a,12b,12cは、予め工場にて精度よく製作される。構造用鉄骨柱12(12a,12b,12c)に固定された梁受け金物30に構造用ラーメン梁であるメイン梁40が図7(B)に示すように側部上方から押し当てられ、落とされて接合される。   First, as shown in FIG. 7 (A), the beam support 30 is fixed to the upper side of each floor of the building of the structural steel column 12 (12a, 12b, 12c) by fastening means such as welding. Actually, the steel column elements 12a, 12b, and 12c to which the beam receiver 30 is fixed are manufactured in advance at a factory with high accuracy. As shown in FIG. 7B, the main beam 40, which is a structural ramen beam, is pressed against the beam support 30 fixed to the structural steel column 12 (12a, 12b, 12c) and dropped. Are joined.

メイン梁40の端部は、梁受け金物30に接合される際、図8(A)および(B)に示すように、予め工場のプレカットマシンで成形されたスリット溝43がガイドプレート33の上部に沿ってベースプレート31側に導かれつつ押し当てられ、メイン梁40の係合ガイド孔44が梁受け金物30のガイドピン(ロケットピン)34の先端側に係合し、この係合状態を保ってメイン梁40がガイドピン34に案内されて落されることで、メイン梁40の端部は、梁受け金物30のベースプレート31側に引き寄せられて押圧移動されつつ、サポートプレート32上にスライド移動して安定的に保持される。   When the end portion of the main beam 40 is joined to the beam receiver 30, as shown in FIGS. 8A and 8B, a slit groove 43 formed in advance by a pre-cut machine in a factory is formed above the guide plate 33. The engagement guide hole 44 of the main beam 40 is engaged with the distal end side of the guide pin (rocket pin) 34 of the beam receiver 30 and is maintained in this engagement state. As the main beam 40 is guided and dropped by the guide pin 34, the end of the main beam 40 is slid onto the support plate 32 while being pulled toward and pressed against the base plate 31 side of the beam receiver 30. And is held stably.

メイン梁40は、その係合ガイド孔44が梁受け金物30のガイドピン34に係合して案内されつつ、構造用鉄骨柱12(ベースプレート31)側に引き寄せられて落されることで、梁受け金物30のサポートプレート32上に当接して支持される。その際、メイン梁40の端部底部にプレート受け溝45が形成されており、メイン梁40が梁受け金物30上に当接して支持されるとき、メイン梁40の底面が梁受け金物30のサポートプレート32の底面と面一となるように構成され、梁受け金物30とメイン梁40との接合構造の美感が保たれている。 The main beam 40 is pulled and dropped toward the structural steel column 12 (base plate 31) side while the engagement guide hole 44 is engaged and guided by the guide pin 34 of the beam receiving member 30 , thereby the beam. The support 30 is in contact with and supported on the support plate 32 of the receiving piece 30. At that time, a plate receiving groove 45 is formed at the bottom of the end portion of the main beam 40, and when the main beam 40 is supported on and supported on the beam receiving metal 30, the bottom surface of the main beam 40 is the surface of the beam receiving metal 30. The support plate 32 is configured to be flush with the bottom surface of the support plate 32, and the aesthetic feeling of the joint structure between the beam receiving metal 30 and the main beam 40 is maintained.

メイン梁40の端部が構造用鉄骨柱12に、梁受け金物30のサポートプレート32上に載置され、ガイドピン34で抜止めされた状態で、図7(C)に示すように複数のドリフトピン35が打たれて一体的に結合され、メイン梁40は角筒状の構造用鉄骨柱12に強固に安定的に接合されて構造梁を構成したラーメン梁となる。   The end of the main beam 40 is placed on the structural steel column 12 on the support plate 32 of the beam support 30 and is secured by the guide pins 34, as shown in FIG. The drift pin 35 is struck and joined together, and the main beam 40 is firmly and stably joined to the rectangular tubular structural steel column 12 to form a rigid beam constituting the structural beam.

メイン梁40の端部には(梁受け金物30の)ガイドプレート33の各通し孔36にそれぞれ対応した位置に各ピン孔46が形成される。構造用鉄骨柱12の梁受け金物30にメイン梁40が支持された状態で、各ピン孔46の一方側から複数のドリフトピン35(図8参照)が打たれてメイン梁40の抜止めが行なわれ、メイン梁40は角筒状の構造用鉄骨柱12(12a,12b,12c)に強固に結合される。   At the end of the main beam 40, pin holes 46 are formed at positions corresponding to the through holes 36 of the guide plate 33 (of the beam receiver 30). In a state where the main beam 40 is supported by the beam receiver 30 of the structural steel column 12, a plurality of drift pins 35 (see FIG. 8) are hit from one side of each pin hole 46 to prevent the main beam 40 from being removed. In practice, the main beam 40 is firmly coupled to the rectangular steel structural steel column 12 (12a, 12b, 12c).

また、メイン梁40に直交するように、図示しない床梁が梁受け金具(不図示)を介して接合される建物各階のメイン梁40と床梁の上面が面一に構成され、メイン梁40と床梁上に図9に示される構造用の床パネル48が敷設される。構造用の床パネル48の敷設により木造建築物10は、建物2階以上の床面が構成される。   Further, the main beam 40 on each floor of the building and the upper surface of the floor beam are joined to each other so that the floor beam (not shown) is joined via a beam receiving bracket (not shown) so as to be orthogonal to the main beam 40. A structural floor panel 48 shown in FIG. 9 is laid on the floor beam. By laying the structural floor panel 48, the wooden building 10 has a floor surface of the second floor or more of the building.

このようにして、図1に示すように、建物各階のメイン梁40は、その両端部が対向する角筒状の構造用鉄骨柱12(12a,12b,12c)に、梁受け金物30を用いて一体的に結合され、強固な接合構造となり、構造梁のラーメン梁を構成している。メイン梁40は、大断面の天然木材の構造用集成材を使用し、構造用鉄骨柱12に梁受け金物30を用いてメイン梁40を構造用鉄骨柱12に固定させ、門型ラーメン構造の木造建築物10とすることで、接合強度を向上させ、耐震性、耐久性を向上させることができる。   In this way, as shown in FIG. 1, the main beam 40 on each floor of the building uses the beam receiving hardware 30 on the rectangular tubular structural steel column 12 (12a, 12b, 12c) whose both ends are opposed to each other. Are combined together to form a rigid joint structure, which constitutes a structural beam. The main beam 40 is made of a structural laminate of natural wood having a large cross section, and the main beam 40 is fixed to the structural steel column 12 by using the beam receiving metal 30 on the structural steel column 12 to form a portal ramen structure. By setting it as the wooden building 10, joint strength can be improved and an earthquake resistance and durability can be improved.

また、第1実施形態に用いられる軸組み構造の木造建築物10では、柱脚金物14、柱脚柱頭金物22および梁受け金物30に球状黒鉛鋳鉄(ダクタイル)等の鋳物材料製作された鋳物製品や鉄鋼製品が使用される。 Furthermore, the wooden structure 10 of Jikukumi structure used in the first embodiment, the column base hardware 14 was fabricated by casting the material of the spherical graphite cast iron (ductile) or the like column base stigma hardware 22 and the beam receiving hardware 30 castings Products and steel products are used.

さらに、図1に示される木造建築物10は、角筒状の構造用鉄骨柱12に固定の梁受け金物30に大断面の木製構造梁のメイン梁40を一体接合させた軸組みを、床パネル48、壁パネル49および屋根パネル26で支えるパネル組立構造で構成した建物である。特に、建物基部13の柱脚金物14に堅固に立設された構造用鉄骨柱12に固定の梁受け金物30に、大断面のメイン梁40を一体接合させた軸組みに、床パネル(48)および壁パネル(49)で支えるボックス組立構造を建物内に構成したものである。   Further, the wooden building 10 shown in FIG. 1 has a shaft structure in which a main beam 40 of a large-sized wooden structural beam is integrally joined to a beam receiving fixture 30 fixed to a square steel tubular structural column 12. It is a building composed of a panel assembly structure supported by the panel 48, the wall panel 49 and the roof panel 26. In particular, a floor panel (48) is constructed in such a manner that a main beam 40 having a large cross section is integrally joined to a beam receiving bracket 30 fixed to a structural steel column 12 firmly erected on a column base metal 14 of a building base 13. ) And a box assembly structure supported by the wall panel (49) is constructed in the building.

床パネル48は、図9に示すように、在来軸組立法の約10倍の強度を有する厚さ数10mm(例えば28mm)の構造用床パネルが採用され、構造梁のメイン梁40や床梁(不図示)上に設置される。床パネル48のパネル寸法は、一例として厚さ数10(28)mmで縦・横が3000(3600,2720,2000,1820)mm×1220(1000,910)mmである。床パネル48は、ピアノ等の重量物に耐える強度を有する構造用床パネルである。   As the floor panel 48, as shown in FIG. 9, a structural floor panel having a thickness of about 10 mm (for example, 28 mm) having a strength about 10 times that of the conventional shaft assembling method is adopted. It is installed on a beam (not shown). The panel dimensions of the floor panel 48 are, for example, a thickness of several tens (28) mm and length and width of 3000 (3600, 2720, 2000, 1820) mm × 1220 (1000, 910) mm. The floor panel 48 is a structural floor panel having strength to withstand heavy objects such as a piano.

また、壁パネル49と屋根パネル26は、硬質ウレタン、発泡スチロール等の断熱材50を一体化し、木質系ボード52で覆った断熱パネルである。符号53は材木あるいは管柱である。壁パネル49は窓等の開口部、床パネル48は柱位置に合せてプレカットされる。   Further, the wall panel 49 and the roof panel 26 are heat insulating panels in which a heat insulating material 50 such as hard urethane or polystyrene foam is integrated and covered with a wooden board 52. Reference numeral 53 denotes a timber or a pipe column. The wall panel 49 is pre-cut according to the opening of a window or the like, and the floor panel 48 according to the column position.

さらに、屋根パネル26は、2枚の構造用合板54,54間に断熱材50を挟み込んだものである。屋根パネル26は、屋根27の取合いに合せてプレカットされる。特に屋根パネル26のプレカットマシン(不図示)は三次元形状のカットが可能で、複雑な屋根形状に対応することができる。符号55は桟材である。   Further, the roof panel 26 is obtained by sandwiching a heat insulating material 50 between two structural plywoods 54 and 54. The roof panel 26 is precut according to the engagement of the roof 27. In particular, a precut machine (not shown) for the roof panel 26 can cut a three-dimensional shape and can cope with a complicated roof shape. Reference numeral 55 denotes a crosspiece.

このように、床パネル48、壁パネル49および屋根パネル26は、プレカットマシンにより複雑な形状に予めプレカットされる。   Thus, the floor panel 48, the wall panel 49, and the roof panel 26 are precut in advance into a complicated shape by the precut machine.

そして、図1に示される木造3階建ての木造建築物10は、前述したように建物基部13の柱脚金物14上で堅固に立設された角筒状の構造用鉄骨柱12に、梁受け金物30が予め固定され、この梁受け金物30に、構造梁(ラーメン梁)である大断面のメイン梁40を一体に接合される軸組みを、床パネル48および壁パネル49あるいは屋根パネル26で支えるボックス構造に構成される。現在まで数多くの破壊試験や国立研究開発法人防災科学技術研究所での公開大耐震試験では、阪神淡路大震災の2倍(1600ガル)以上の激震や、伊勢湾台風クラス(60m/sec)の暴風に耐えることがわかっている。壁パネル49に、例えば厚さ9mmの構造用合板51と厚さ50mmの硬質ウレタン製の断熱材50を用いたものでは、壁倍率2.9倍の強度を有することが知られている。   Then, the wooden three-story wooden building 10 shown in FIG. 1 is attached to the rectangular tubular structural steel column 12 firmly standing on the column base 14 of the building base 13 as described above. A receiving bracket 30 is fixed in advance, and a shaft assembly in which a main beam 40 having a large cross section, which is a structural beam (ramen beam), is integrally joined to the beam receiving bracket 30 is used as a floor panel 48 and a wall panel 49 or a roof panel 26. The box structure is supported by To date, in many destructive tests and public large earthquake resistance tests at the National Research Institute for Earth Science and Disaster Prevention, there were more than twice as many earthquakes (1600 gal) as the Great Hanshin-Awaji Earthquake and storms in the Isewan typhoon class (60 m / sec) Is known to withstand For example, a structural panel 51 having a thickness of 9 mm and a heat insulating material 50 made of hard urethane having a thickness of 50 mm are used as the wall panel 49 and have a wall magnification of 2.9 times.

また、メイン梁40は、梁受け金物30により構造用鉄骨柱12に一体的に接合される。梁受け金物30に一体のサポートプレート32は、メイン梁40の端部下部の位置決めを確実にして、メイン梁40を安定的に保持するので、構造用鉄骨柱12とメイン梁40との接合部の剪断力を高め、梁受け金物30周囲のメイン梁40の割れを防止したり、軸組みの初期剛性と地震後の復元力を高める機能を有する。   Further, the main beam 40 is integrally joined to the structural steel column 12 by the beam receiver 30. The support plate 32 integrated with the beam receiving member 30 ensures the positioning of the lower end portion of the main beam 40 and stably holds the main beam 40, so that the joint between the structural steel column 12 and the main beam 40 is provided. The shearing force is increased, the main beam 40 around the beam receiver 30 is prevented from cracking, and the initial rigidity of the shaft assembly and the restoring force after the earthquake are increased.

さらに、梁受け金物30のサポートプレート32は、メイン梁40のスリット溝43の下部を塞ぎファイヤストップ対策を施すことができるので、火災時の炎の拡散を防ぐことができ、ファイヤストップ効果で木造建築物10の倒壊を防ぐことができることが確認されている。構造用鉄骨柱12と構造梁のメイン梁40とを梁受け金物30を用いて一体的に接合した木造建築物10は、耐震性、耐久性に優れ、火災や地震の災害に強い建物となる。   Furthermore, since the support plate 32 of the beam receiver 30 can close the lower portion of the slit groove 43 of the main beam 40 and take a fire-stop measure, it can prevent the spread of flames in the event of a fire, and the fire-stop effect makes the wooden structure It has been confirmed that the building 10 can be prevented from collapsing. The wooden building 10 in which the structural steel column 12 and the main beam 40 of the structural beam are integrally joined using the beam receiving metal 30 is excellent in earthquake resistance and durability, and becomes a building resistant to fire and earthquake disasters. .

Are used for structural laminates with large cross-sections of 120 mm × 450 mm, 120 mm × 380 mm and 120 mm × 300 mm, respectively. The four-story wooden building 60 is configured such that the beam height (H) of the main beam 81 gradually decreases from the main beam 81, which is a structural beam on the first floor of the building, toward the upper floor. For the main beam 81 on each floor of the building, a structural glulam with a large cross section is used as a structural beam (ramen beam).

また、建物各階のメイン梁81には、図14に示すように、床梁82が梁受け金物(不図示)を経て直交するように接合され、メイン梁81と床梁82の上面が面一(平面)となるように配設される。建物各階のメイン梁81および床梁82上に図9に示される構造用の床パネル48が敷設される。建物4階(最上階)のメイン梁81および床梁82上には、構造用の床パネル48より肉薄で、例えば、肉厚20mm程度の床パネル83が敷設され、天井裏部屋84が構成される。   Further, as shown in FIG. 14, a floor beam 82 is joined to the main beam 81 on each floor of the building so as to be orthogonal to each other through a beam receiver (not shown), and the upper surfaces of the main beam 81 and the floor beam 82 are flush with each other. (Planar). A structural floor panel 48 shown in FIG. 9 is laid on the main beam 81 and the floor beam 82 of each floor of the building. On the main beam 81 and the floor beam 82 on the fourth floor (top floor) of the building, a floor panel 83 that is thinner than the structural floor panel 48 and has a thickness of, for example, about 20 mm is laid to form a ceiling back room 84. The

A box assembly structure supported by a structural floor panel (48) and a wall panel 49 is constructed in the building.

また、構造用の床パネル48、屋根裏の床パネル83、壁パネル49および屋根パネル26は、三次元のプレカットマシン(不図示)で三次元形状にプレカットされる。構造用の床パネル48は、構造用鉄骨柱61の各柱位置に、壁パネル49は、窓等の開口部に合せてそれぞれプレカットされる。このように、構造用の床パネル48、床パネル83、壁パネル49および屋根パネル26等はプレカットマシンにより複雑な形状に、品質管理された工場で精度高くプレカットされる。   The structural floor panel 48, the attic floor panel 83, the wall panel 49, and the roof panel 26 are pre-cut into a three-dimensional shape by a three-dimensional pre-cut machine (not shown). The structural floor panel 48 is pre-cut at each column position of the structural steel column 61, and the wall panel 49 is pre-cut according to an opening such as a window. In this way, the structural floor panel 48, the floor panel 83, the wall panel 49, the roof panel 26, and the like are pre-cut into a complicated shape by a pre-cut machine with high accuracy in a quality-controlled factory.

さらに、木造建築物60の4階建て建物は、建物外壁周りに立設される角筒状の構造用鉄骨柱61は、少なくとも建物室内側に防耐火被覆材85あるいは化粧板がアクリル樹脂等の接着剤で接着され、被覆される。さらに、4階建ての建物内部に立設される構造用鉄骨柱61には、全周面に亘り外側から防耐火被覆材85あるいは化粧板が接着剤で接着され、被覆される。防耐火被覆材85は、化粧板を兼ねている。   Further, in the four-story building of the wooden building 60, the square cylindrical structural steel column 61 standing around the outer wall of the building has at least a fireproof covering material 85 or a decorative board made of acrylic resin or the like on the building interior side. Glued with an adhesive and coated. Furthermore, the structural steel column 61 erected inside the four-story building is covered with a fire-proof covering material 85 or a decorative board with an adhesive from the outside over the entire peripheral surface. The fireproof covering material 85 also serves as a decorative board.

また、防耐火被覆材85は、市販品で構成され、構造用鉄骨柱61や木製のメイン梁等に接着剤で接着され、被覆状態で使用される。市販品の耐火1時間用の被覆材として、構造用鉄骨柱61には、例えばクリオン株式会社製のクリオンエースボード(FD060CN−9405)、旭化成建材株式会社製のヘーベルライト(FP060CN−945)、住友金属鉱山シボレックス株式会社製のシボレックス(FP060CN−9405)等の防耐火被覆材85がある。   Moreover, the fireproof covering material 85 is comprised by a commercial item, and is adhere | attached with the adhesive agent on the structural steel pillar 61, a wooden main beam, etc., and is used in a covering state. As a commercially available one hour fireproof covering material, structural steel column 61 includes, for example, CLION ACE BOARD (FD060CN-9405) manufactured by Clion Co., Ltd., Heberlite (FP060CN-945) manufactured by Asahi Kasei Construction Materials Co., Ltd., Sumitomo There is a fire-proof coating material 85 such as Siborex (FP060CN-9405) manufactured by Metal Mining Cibolex.

さらに、木造建築物60の木造柱、梁、床、壁用に耐火1時間用被覆材として、防耐火被覆材がある。この防耐火被覆材は、強化石膏ボード2枚以上で厚さ計42mm以上を両面に重ねて構成される。   Furthermore, there is a fireproof and fireproof covering material as a fireproof 1 hour covering material for wooden pillars, beams, floors and walls of the wooden building 60. The fireproof covering material is composed of two or more reinforced gypsum boards and a thickness of 42 mm or more stacked on both sides.

ところで、建築基準法では、「1時間耐火」が認められた木材は4階建て迄で、「2時間耐火」は14階建て迄の建物に木材を使用することができる。(高層建物の)一般の木造建築物における建築基準法上の耐火仕様は、建物の適用階に応じて用いられ、図17に示すように適合する耐火時間が定められている。   By the way, according to the Building Standard Law, timber approved for “1 hour fire resistance” can be used for buildings up to 4 stories, and “2 hour fire resistance” can be used for buildings up to 14 stories. The fireproof specifications in the building standard law for general wooden buildings (of high-rise buildings) are used according to the floor of application of the building, and a suitable fireproof time is defined as shown in FIG.

また、準耐火建築物や一般の木造建築物の柱や梁の燃えしろ深さは、図18に示すように規定されている(S62建告第1902号、改正 H16国告第333号)。   Further, the burn-in depth of pillars and beams of semi-refractory buildings and general wooden buildings is defined as shown in FIG. 18 (S62 Building No. 1902, Revision H16 National Notification No. 333).

集成材や積層材を使用した場合、準耐火建築物の柱や梁の燃えしろは、1時間耐火で45mm、45分耐火で35mmである。一般の木造建築物の柱や梁の燃えしろは、30分耐火で25mmである。   When laminated or laminated materials are used, the column and beam burnout of the semi-refractory building is 45 mm for 1 hour fire resistance and 35 mm for 45 minutes fire resistance. The pillars and beams of ordinary wooden buildings have a fire resistance of 30 minutes and 25 mm.

ところで、第2実施形態に示された4階建ての木造建築物60は、建物基部63上に立設される各構造用鉄骨柱61を、柱脚金物64に柱脚ベースパック67および複数本(4本)のアンカーボルト66、締結ナット68を用いて緊締し、立設される。立設された構造用鉄骨柱61には固定の梁受け金物80に構造梁のメイン梁81が、第1実施形態に示された木造建築物10と同様接合され、一体化される。   By the way, in the four-story wooden building 60 shown in the second embodiment, each structural steel column 61 erected on the building base 63 is connected to the column base hardware 64 and the column base pack 67 and a plurality ( The four bolts are fastened using the anchor bolts 66 and the fastening nuts 68, and are erected. In the standing structural steel column 61, the main beam 81 of the structural beam is joined to and integrated with the fixed beam receiving member 80 in the same manner as the wooden building 10 shown in the first embodiment.

各構造用鉄骨柱61は、建物基部63の土台部分で、地震や台風等の自然災害による引抜き力を受けても、建物基部63に柱脚金物64、柱脚ベースパック67および複数(4本)のアンカーボルト66等で緊締され、堅固に固定される。   Each structural steel column 61 is a base portion of the building base 63, and even if it receives a pulling force due to a natural disaster such as an earthquake or a typhoon, the building base 63 has a column base 64, a column base pack 67, and a plurality (four). The bolts are tightened with an anchor bolt 66 or the like, and firmly fixed.

また、構造梁である大断面のメイン梁81は、構造用鉄骨柱61に固定の梁受け金物80を用いて堅固に接合され、一体化される。しかも、梁受け金物80は構造梁であるメイン梁81の端部をサポートプレート上に載置して支持する。梁受け金物80のサポートプレートは、梁受け金物80のガイドプレートに案内されるメイン梁81のスリット溝の下部を塞いでいる。したがって、万一の火災時には、梁受け金物80のサポートプレートが、メイン梁81のスリット溝を塞ぎ、ファイヤストップ効果が作用するので、メイン梁81の落下を防ぐことができ、建物の倒壊を防止することができる。さらに、角筒状の構造用鉄骨柱61は建物各階の隣接する鉄骨柱エレメント61a〜61d同士が拡開防止板で一体に固定されるので、構造用鉄骨柱61は建物各階毎に節部ができ、開き止めされるので、剛性や強度を向上させることができる。   The main beam 81 having a large cross section, which is a structural beam, is firmly joined to the structural steel column 61 using a fixed beam receiving member 80 and integrated. Moreover, the beam receiver 80 supports the end of the main beam 81, which is a structural beam, by placing it on the support plate. The support plate of the beam receiver 80 closes the lower part of the slit groove of the main beam 81 guided by the guide plate of the beam receiver 80. Therefore, in the unlikely event of a fire, the support plate of the beam receiver 80 blocks the slit groove of the main beam 81, and the fire stop effect acts, so that the main beam 81 can be prevented from falling and the building can be prevented from collapsing. can do. Furthermore, since the steel column elements 61a to 61d adjacent to each other on each floor of the building are fixed integrally with the spread prevention plate, the structural steel column 61 has a node portion on each floor of the building. Since it is prevented from opening, rigidity and strength can be improved.

さらに、角筒状の構造用鉄骨柱61と構造梁のメイン梁81とを梁受け金物80を介して強固に接合しており、梁受け金物80は構造用鉄骨柱61とメイン梁81との接合部分の剪断力を高めることができる。梁受け金物80によりメイン梁81の割れを防止でき、軸組み構造の初期剛性と地震後の復元力を高めることができる。   Further, the structural steel column 61 in the form of a square tube and the main beam 81 of the structural beam are firmly joined via a beam receiving fixture 80, and the beam receiving fixture 80 is connected to the structural steel column 61 and the main beam 81. The shearing force of the joint portion can be increased. The beam receiver 80 can prevent the main beam 81 from cracking, and can increase the initial rigidity of the frame structure and the restoring force after the earthquake.

加えて、図13および図14に示される4階建ての木造建築物60は、建物基部63の柱脚金物64上にアンカーボルト66、締結ナット68で緊締された角筒状の構造用鉄骨柱61が立設され、この構造用鉄骨柱61に固定された梁受け金物80に大断面のメイン梁81が接合される。したがって、建物基部63の柱脚金物64上に緊締された構造用鉄骨柱61やこの構造用鉄骨柱61に梁受け金物80により接合されたメイン梁81を備えた木造建築物60は、激震にもびくつかない耐震性と耐久性とを備えた木造建築物の建物を提供することができる。   In addition, the four-story wooden building 60 shown in FIG. 13 and FIG. 14 is a rectangular tubular structural steel column fastened with anchor bolts 66 and fastening nuts 68 on the column base metal 64 of the building base 63. 61 is erected, and a main beam 81 having a large cross section is joined to a beam receiver 80 fixed to the structural steel column 61. Therefore, the structural steel column 61 fastened on the column base metal 64 of the building base 63 and the wooden building 60 including the main beam 81 joined to the structural steel column 61 by the beam receiving member 80 are subjected to a strong earthquake. It is possible to provide a wooden building with anti-vibration resistance and durability.

したがって、4階建ての建物を木造建築物60としても、第1実施形態に示された3階建ての木造建築物10と同様に、耐久性、耐震性のある建物を提供することができる。加えて、公共建築物木材利用促進法が2010年に施行されたのに伴い、木造の公共施設が増えており、一般住宅においても、木造建築物60に3階建ての建物のみならず、4階建ての建物が増加している。   Therefore, even if the four-story building is used as the wooden building 60, a building having durability and earthquake resistance can be provided in the same manner as the three-story wooden building 10 shown in the first embodiment. In addition, as the Public Building Timber Utilization Promotion Law came into effect in 2010, the number of wooden public facilities has increased, and not only three-story buildings in wooden buildings 60 but also 4 The number of floor buildings is increasing.

[第2実施形態の変形例]

A small beam 86 that is not a structural beam is joined to the other side of the steel column 61 by a beam receiving hardware 87 that does not include a support plate. The beam height of the small beam 86 is lower than the beam height of the main beam 81 which is a structural beam, for example, 240 mm. The small beam 86 forms a floor beam or the like. The small beam 86 is supported by a pipe column or small column 88 standing on the base 76.
