Description

本発明は、柱材、柱材と部材の仕口、柱材又は仕口を備える建築物、柱材の製法及び建築物の工法に関する。 The present invention relates to a pillar, a joint between a pillar and a member, a building provided with the pillar or a joint, a method for manufacturing the pillar, and a construction method for the building.

例えば、下記特許文献１は、柱と梁の仕口を開示している。この文献には、梁を柱に接合するために、角形鋼管からなる柱材の側面にブラケットを溶接すること、及びブラケットと梁がプレートを介してボルトで固定されることが記載されている。 For example, Patent Literature 1 below discloses a joint between a column and a beam. This document describes that, in order to join the beam to the column, a bracket is welded to the side surface of a column material made of square steel pipe, and the bracket and the beam are fixed with bolts via a plate.

しかしながら、この文献に記載された技術では、梁を柱に直接接合することができず、ブラケットやプレートを多用しなければならないという不具合がある。また、この技術では、柱材の側面に突起物（ブラケット）があるため、柱材をガイドとして部材を移動させることができない。 However, with the technique described in this document, the beam cannot be directly joined to the column, and there is a problem that many brackets and plates must be used. Moreover, in this technique, since there is a protrusion (bracket) on the side surface of the pillar, the member cannot be moved using the pillar as a guide.

以下、図面を参照しながら本発明の実施形態を具体的に説明するが、本発明の技術的範囲は以下の説明の内容に限定されるものではない。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings, but the technical scope of the present invention is not limited to the contents of the following description.

図１に示したように、本発明の柱材１０は、角形鋼管２０、プレート３０及び溶接ナット４０を備えている。 As shown in FIG. 1, the post material 10 of the present invention comprises a square steel pipe 20, a plate 30 and a weld nut 40. As shown in FIG.

角形鋼管２０は、第１孔部２１を有する。第１孔部２１は、角形鋼管２０の少なくとも１つの側面に形成される。第１孔部２１は、建築物の構造に対応して、例えば、図２に示したように、角形鋼管２０の４つの側面に形成されてもよいし、図３に示したように、角形鋼管２０の互いに平行な２つの側面に形成されてもよい。また、第１孔部２１は、角形鋼管２０の１つの側面に対して、直列に複数形成されてもよいし、並列に複数形成されてもよい。第１孔部２１は、溶接ナット４０と螺合するボルト５０を通すための貫通孔である。 The square steel pipe 20 has a first hole 21 . The first hole 21 is formed in at least one side surface of the square steel pipe 20 . The first holes 21 may be formed on four sides of the square steel pipe 20 as shown in FIG. 2, or may be formed in a square shape as shown in FIG. It may be formed on two sides parallel to each other of the steel pipe 20 . Also, the first holes 21 may be formed in series or in parallel on one side surface of the square steel pipe 20 . The first hole portion 21 is a through hole for passing a bolt 50 that is screwed with the weld nut 40 .

プレート３０は、第１孔部２１が形成された角形鋼管２０の側面の内面に密着している。プレート３０は、第１孔部２１と同軸上に位置する第２孔部３１を有する。第２孔部３１は、溶接ナット４０と螺合するボルト５０を通すための貫通孔である。 The plate 30 is in close contact with the inner surface of the side surface of the rectangular steel pipe 20 in which the first holes 21 are formed. The plate 30 has a second hole 31 positioned coaxially with the first hole 21 . The second hole portion 31 is a through hole for passing a bolt 50 that is screwed with the weld nut 40 .

溶接ナット４０は、プレート３０に溶接されている。溶接ナット４０のねじ穴４１は、第２孔部３１と同軸上に位置している。 A weld nut 40 is welded to the plate 30 . The threaded hole 41 of the weld nut 40 is positioned coaxially with the second hole portion 31 .

本発明の柱材は、以下の方法で製造される。 The pillar material of the present invention is manufactured by the following method.

すなわち、まず、図４に示したように、第１孔部２１及び第３孔部２２を角形鋼管２０の少なくとも１つの側面に形成する。第３孔部２２は、栓溶接に利用される丸穴である。 That is, first, as shown in FIG. 4, the first hole 21 and the third hole 22 are formed in at least one side surface of the rectangular steel pipe 20 . The third hole portion 22 is a round hole used for plug welding.

次に、図５に示したように、第２孔部３１をプレート３０に形成する。なお、第１孔部２１及び第３孔部２２を角形鋼管２０に形成する前に、第２孔部３１をプレート３０に形成してもよい。 Next, as shown in FIG. 5, second holes 31 are formed in the plate 30 . The second hole 31 may be formed in the plate 30 before forming the first hole 21 and the third hole 22 in the rectangular steel pipe 20 .

次に、図６に示したように、溶接ナット４０をプレート３０の表面３０ａに溶接する。この際、溶接ナット４０は、ねじ穴４１が第２孔部３１と同軸上に位置するように配置される。 Next, a weld nut 40 is welded to the surface 30a of the plate 30, as shown in FIG. At this time, the weld nut 40 is arranged so that the screw hole 41 is positioned coaxially with the second hole portion 31 .

次に、図７に示したように、位置決め用ボルト６０を溶接ナット４０に取り付ける。この例では、位置決め用ボルト６０として全ねじボルトを使用している。位置決め用ボルト６０は、プレート３０の裏面３０ｂから突出するように、溶接ナット４０に取り付けられる。 Next, the positioning bolt 60 is attached to the weld nut 40 as shown in FIG. In this example, a fully threaded bolt is used as the positioning bolt 60 . The positioning bolt 60 is attached to the weld nut 40 so as to protrude from the rear surface 30b of the plate 30. As shown in FIG.

次に、図８に示したように、プレート３０を角形鋼管２０の内部に挿入し、位置決め用ボルト６０を第１孔部２１に挿入する。 Next, as shown in FIG. 8 , the plate 30 is inserted into the square steel pipe 20 and the positioning bolt 60 is inserted into the first hole 21 .

次に、図９に示したように、ナットを角形鋼管２０から突出する位置決め用ボルト６０に取り付ける。この例では、位置決め用ボルト６０の取り外しを容易にするために、１つの位置決め用ボルト６０に対して２つのナット（上ナット７１及び下ナット７２）を取り付けている。 Next, as shown in FIG. 9, a nut is attached to the positioning bolt 60 protruding from the square steel pipe 20 . In this example, two nuts (upper nut 71 and lower nut 72) are attached to one positioning bolt 60 in order to facilitate removal of the positioning bolt 60. As shown in FIG.

次に、プレート３０の裏面３０ｂを角形鋼管２０の側面の内面に密着させるために、下ナット７２を締め付ける。これにより、プレート３０は、裏面３０ｂが角形鋼管２０の内面に密着した状態で角形鋼管２０に仮固定される。 Next, the lower nut 72 is tightened so that the back surface 30b of the plate 30 is brought into close contact with the inner surface of the side surface of the rectangular steel pipe 20. As shown in FIG. As a result, the plate 30 is temporarily fixed to the rectangular steel pipe 20 with the back surface 30 b in close contact with the inner surface of the rectangular steel pipe 20 .

次に、第３孔部２２を利用してプレート３０を角形鋼管２０に栓溶接する。 Next, the plate 30 is plug-welded to the rectangular steel pipe 20 using the third hole 22 .

最後に、図１０に示したように、下ナット７２を上ナット７１に接触させた状態で下ナット７２を緩めることにより、ナット（上ナット７１及び下ナット７２）及び位置決め用ボルト６０を取り除いて柱材１０が完成する。 Finally, as shown in FIG. 10, the nuts (upper nut 71 and lower nut 72) and the positioning bolt 60 are removed by loosening the lower nut 72 while keeping the lower nut 72 in contact with the upper nut 71. The pillar material 10 is completed.

本発明の柱材は、溶接ナット４０が溶接されたプレート３０を角形鋼管２０の側面の内面に密着させることにより、作業者の手が届かず、また、特殊な工具を用いてもナットの回転を抑えることが困難な位置に、部材の取り付けに用いられるボルト５０と螺合するナット（溶接ナット４０）を配置することができる。プレート３０は、角形鋼管２０に密着しているため、角形鋼管２０の補強材として機能し得る。また、プレート３０は、座金の役割を果たすこともできる。 In the post material of the present invention, the plate 30 to which the welding nut 40 is welded is brought into close contact with the inner surface of the side surface of the square steel pipe 20, so that the operator cannot reach it, and even if a special tool is used, the rotation of the nut can be prevented. A nut (welding nut 40) that screws together with a bolt 50 used for attaching the member can be arranged at a position where it is difficult to hold down. Since the plate 30 is in close contact with the square steel pipe 20 , it can function as a reinforcing material for the square steel pipe 20 . Plate 30 can also act as a washer.

本発明の柱材によれば、梁などの部材を柱材１０に直接接合することができる。すなわち、本発明の柱材と部材の仕口は、図１１及び図１２に示したように、柱材１０を構成する角形鋼管２０の少なくとも１つの側面に形成される第１孔部２１と、第１孔部２１と同軸上に位置するように第１孔部２１が形成された角形鋼管２０の側面の内面に密着するプレート３０に形成される第２孔部３１と、ねじ穴４１が第２孔部３１と同軸上に位置するようにプレート３０に溶接される溶接ナット４０と、柱材１０に接合される部材８０に形成される第４孔部８１と、第４孔部８１、第１孔部２１及び第２孔部３１に挿入され、かつ溶接ナット４０と螺合するボルト５０を備えて構成される。したがって、従来、柱材と部材の間に介在していたブラケットやプレートが不要である。 According to the pillar material of the present invention, members such as beams can be directly joined to the pillar material 10 . That is, as shown in FIGS. 11 and 12, the connection between the column material and the member of the present invention includes a first hole 21 formed in at least one side surface of the square steel pipe 20 constituting the column material 10, A second hole 31 formed in a plate 30 that is in close contact with the inner surface of the side surface of the square steel pipe 20 in which the first hole 21 is formed so as to be coaxial with the first hole 21, and a screw hole 41 A weld nut 40 welded to the plate 30 so as to be coaxial with the second hole 31, a fourth hole 81 formed in a member 80 joined to the column material 10, a fourth hole 81, a second The bolt 50 is inserted into the first hole 21 and the second hole 31 and screwed with the weld nut 40 . Therefore, there is no need for brackets or plates that have conventionally been interposed between the pillars and members.

本発明の柱材によれば、部材８０の接合に用いられるボルト５０と螺合する溶接ナット４０が角形鋼管２０の内部に配置されるため、柱材１０の側面から突出する突起物をなくすことができる。したがって、本発明の柱材を建築物に適用した場合には、以下の工法を実現することが可能になる。 According to the post material of the present invention, since the weld nut 40 screwed with the bolt 50 used for joining the member 80 is arranged inside the square steel pipe 20, the projection protruding from the side surface of the post material 10 is eliminated. can be done. Therefore, when the pillar material of the present invention is applied to a building, it becomes possible to realize the following construction method.

すなわち、この工法では、まず、図１３に示したように、柱材１０を基礎９０の上に設置し、柱材１０に接合される部材であるトラス梁８２を基礎９０の上で組み立てる。この例では、建築物が軽量鉄骨造であるが、本発明の柱材は、重量鉄骨造の建築物にも適用可能である。また、この例では、トラス梁８２とトラス桁８３が基礎９０の上で矩形に組み合わされている。トラス梁８２及びトラス桁８３は、それぞれ、軽量形鋼からなる弦材８２ａ，８３ａ及び斜材８２ｂ，８３ｂで構成されている。この例では、トラス梁８２及びトラス桁８３の組み立てを基礎９０の上で行えるので、これらを高所で組み立てる場合と比較して、組み立てが非常に容易であり、工数も大幅に削減できる。また、資材の運搬も効率的に実施できる。さらに、基礎９０以外の場所でこれらを組み立てる場合と比較して、作業スペースを大幅に削減できる。 That is, in this construction method, first, as shown in FIG. In this example, the building is of light steel construction, but the pillar material of the present invention can also be applied to heavy steel construction. Also, in this example, the truss beam 82 and the truss girder 83 are combined on the foundation 90 in a rectangular shape. The truss beam 82 and the truss girder 83 are respectively composed of chord members 82a, 83a and diagonal members 82b, 83b made of lightweight shaped steel. In this example, since the truss beam 82 and the truss girder 83 can be assembled on the foundation 90, compared to assembling them at a high place, the assembly is very easy and the man-hours can be greatly reduced. In addition, materials can be efficiently transported. Furthermore, compared to assembling them at a location other than the foundation 90, the working space can be greatly reduced.

次に、図１４に示したように、柱材１０をガイドとしてトラス梁８２を所定の高さまで上昇させる。本発明の柱材は、柱材１０の側面から突出する突起物がないため、トラス梁８２の弦材８２ａを柱材１０に接触させながらトラス梁８２の取り付け位置までトラス梁８２を移動させることができる。この例では、柱材１０がガイドとして機能し、それにより、柱材１０とトラス梁８２との衝突を回避でき、また、移動中のトラス梁８２を水平に維持し易いため、トラス梁８２の吊り作業が格段に容易となる。また、昇降機を用いてトラス梁８２を安全に上昇させることも可能になる。 Next, as shown in FIG. 14, the truss beam 82 is raised to a predetermined height using the column material 10 as a guide. Since the post material of the present invention does not have a protrusion protruding from the side surface of the post material 10, the truss beam 82 can be moved to the mounting position of the truss beam 82 while keeping the chord material 82a of the truss beam 82 in contact with the post material 10. can be done. In this example, the column material 10 functions as a guide, thereby avoiding a collision between the column material 10 and the truss beam 82, and also because the truss beam 82 can be easily maintained horizontally during movement. Suspension work becomes much easier. It also becomes possible to safely lift the truss beam 82 using an elevator.

次に、ボルト５０と溶接ナット４０を螺合してトラス梁８２を柱材１０に接合する。ボルト５０は、トラス梁８２の弦材８２ａに形成される第４孔部８１、第２孔部３１及び第１孔部２１に挿入され、溶接ナット４０と螺合する（図１２参照）。 Next, the bolt 50 and the weld nut 40 are screwed together to join the truss beam 82 to the column material 10 . The bolt 50 is inserted into the fourth hole 81, the second hole 31 and the first hole 21 formed in the chord member 82a of the truss beam 82, and screwed with the weld nut 40 (see FIG. 12).

比較例Comparative example

比較例１の仕口は、図１５に示したように、角形鋼管２０’の互いに平行な２つの側面に第１孔部２１’が形成される柱材１０’と、第４孔部８１’を有し、柱材１０’に接合される部材８０’と、第４孔部８１’及び第１孔部２１’に挿入されるボルト５０’と、ボルト５０’と螺合し、角形鋼管２０’の側面の外面に密着するナット１００を備えている。 As shown in FIG. 15, the connection of Comparative Example 1 includes a column material 10' in which first hole portions 21' are formed in two parallel side surfaces of a rectangular steel pipe 20', and a fourth hole portion 81'. A member 80 ' joined to the column material 10 ', a bolt 50 ' inserted into the fourth hole 81 ' and the first hole 21 ', and the bolt 50 ' are screwed together, and the square steel pipe 20 ' is equipped with a nut 100 which is closely attached to the outer surface of the side surface of '.

比較例１の仕口では、ナット１００が角形鋼管２０’の外部に設けられているため、ボルト５０’を締めることによって、角形鋼管２０’に歪みが発生するという欠点がある。この点、本発明の仕口は、溶接ナット４０が角形鋼管２０の内部に設けられているため、ボルト５０を強く締めても角形鋼管２０に歪みが発生しないという利点がある（図１２参照）。 In the connection of Comparative Example 1, since the nut 100 is provided outside the rectangular steel pipe 20', tightening the bolt 50' causes distortion in the rectangular steel pipe 20'. In this respect, the joint of the present invention has the advantage that the weld nut 40 is provided inside the square steel pipe 20, so that even if the bolt 50 is strongly tightened, the square steel pipe 20 is not distorted (see FIG. 12). .

比較例２の柱材は、図１６に示したように、２本のリップ溝形鋼１０１，１０２を溶接して形成される管材１０３、リップ溝形鋼１０１のウェブ１０１ａに形成される第１孔部２１”、及びねじ穴４１”が第１孔部２１”と同軸上に位置するようにリップ溝形鋼１０１のウェブ１０１ａに溶接される溶接ナット４０”を備えている。 As shown in FIG. 16, the column material of Comparative Example 2 includes a pipe material 103 formed by welding two lip channel steels 101 and 102, and a first joint formed on the web 101a of the lip channel steel 101. It has a hole 21'' and a weld nut 40'' which is welded to the web 101a of the lip channel steel 101 so that the threaded hole 41'' is coaxial with the first hole 21''.

比較例２の柱材では、図１７に示したように、２本のリップ溝形鋼１０１，１０２を溶接する前に、溶接ナット４０”をリップ溝形鋼１０１のウェブ１０１ａに溶接することができるため、本発明の柱材のようにプレート３０がなくても、溶接ナット４０”を任意の位置に配置することができる。 In the column material of Comparative Example 2, as shown in FIG. 17, before welding the two lip channel steels 101 and 102, the weld nut 40″ can be welded to the web 101a of the lip channel steel 101. Therefore, even if there is no plate 30 as in the post material of the present invention, the weld nut 40″ can be arranged at any position.

しかしながら、リップ溝形鋼１０１，１０２は、フランジ１０１ｂ，１０２ｂやリップ１０１ｃ，１０２ｃの肉厚が薄いため、これらが変形し易く、断面形状が安定しないという問題がある。その結果、例えば、図１８及び図１９に示したように、柱材１０”の断面形状が不均一となるという欠点がある。この点、本発明の柱材は、管材が角形鋼管２０であるため、柱材１０の断面形状が均一であるという利点がある。 However, since the flanges 101b, 102b and the lips 101c, 102c of the lip channel steels 101, 102 are thin, they are easily deformed and the cross-sectional shape is unstable. As a result, for example, as shown in FIGS. 18 and 19, there is a drawback that the cross-sectional shape of the column material 10″ becomes uneven. In this respect, the column material of the present invention is a square steel pipe 20. Therefore, there is an advantage that the cross-sectional shape of the pillar material 10 is uniform.

また、比較例２の柱材は、管材１０３が２本のリップ溝形鋼１０１，１０２を溶接して形成されるため、概して、角形鋼管と比較して、管材１０３の断面性能が低いという欠点がある。この点、本発明の柱材は、管材が角形鋼管２０であるため、２つの部材を溶接して形成される管材と比較して、断面性能が高いという利点がある。 In addition, in the column material of Comparative Example 2, since the pipe material 103 is formed by welding the two lip channel steels 101 and 102, the cross-sectional performance of the pipe material 103 is generally lower than that of the square steel pipe. There is In this respect, the column material of the present invention has the advantage that the cross-sectional performance is high compared to the pipe material formed by welding two members because the pipe material is the rectangular steel pipe 20 .
