Description

この発明は、閉鎖断面形状を有する鋼製柱およびこの鋼製柱を用いた柱梁接合構造に関する。   The present invention relates to a steel column having a closed cross-sectional shape and a column beam connection structure using the steel column.

特許文献1には、鉄骨の柱の内部にタッププレートを配置し、柱の外面に梁の端部に固定されたエンドプレートを当接させ、このエンドプレートとタッププレートとを柱を介してボルト接合する柱梁接合構造が開示されている。   In Patent Document 1, a tap plate is arranged inside a steel column, an end plate fixed to the end of the beam is brought into contact with the outer surface of the column, and the end plate and the tap plate are bolted through the column. A column beam joint structure to be joined is disclosed.

また、特許文献2には、柱にH形鋼梁を外ダイヤフラムにより接合する柱と梁の接合構造及び方法において、外ダイヤフラムについて溶接を使用することなく柱に取り付け可能とすることが開示されている。   Patent Document 2 discloses that in a column-to-beam joining structure and method for joining an H-shaped steel beam to a column by an outer diaphragm, the outer diaphragm can be attached to the column without using welding. Yes.

しかしながら、上記特許文献1に開示された柱梁接合構造では、パネルゾーンを別部材で構成するために柱を切断しており、このために柱が高コスト化するという欠点がある。また、上記特許文献2に開示された柱梁接合構造では、柱に対してタップ孔の形成や柱切断等の加工をする必要がないものの、分割状態の外ダイヤフラムを相互にボルトで連結するため、部材加工コストや作製コストが割高になる欠点がある。   However, in the column beam connection structure disclosed in Patent Document 1, the column is cut in order to configure the panel zone as a separate member, which has the disadvantage of increasing the cost of the column. In addition, in the column beam connection structure disclosed in Patent Document 2, it is not necessary to form a tapped hole or cut a column on the column, but to connect the divided outer diaphragms with bolts. There is a drawback that the member processing cost and production cost are expensive.

なお、柱自体にタップ孔を形成しておき、梁のエンドプレートに形成した挿通孔に通したボルトを、上記タップ孔に螺合させる柱梁接合構造が知られている。しかし、この構造において、上記タップ孔は上記柱の側面間のアール部からある程度離れて形成されなければならず、このように距離があると、上記ボルトが柱を引っ張る状態および上記エンドプレートが柱を圧縮する状態の両方において、上記アール部に大きな荷重がかかり変形するおそれがある。   A column-beam joining structure is known in which a tapped hole is formed in the column itself, and a bolt passed through an insertion hole formed in the end plate of the beam is screwed into the tapped hole. However, in this structure, the tap hole must be formed to some extent away from the rounded portion between the side surfaces of the column, and when there is such a distance, the bolt pulls the column and the end plate has a column. In both of the states of compressing, there is a possibility that a large load is applied to the rounded portion and it is deformed.

この発明は、上記の事情に鑑み、柱自体を加工する必要がなく、また、柱の側面間にアール部が存在する場合でも、このアール部の変形を抑制できる鋼製柱および柱梁接合構造を提供する。   In view of the above circumstances, the present invention eliminates the need to process the column itself, and even when there is a round portion between the side surfaces of the column, the steel column and the beam-column connecting structure that can suppress deformation of the round portion I will provide a.

この発明の鋼製柱は、上記の課題を解決するために、ボルト締結用のタップ孔が形成された支持鋼材が、閉鎖断面を有する鋼製の柱本体の側面に、ボルトを用いずに接合されていることを特徴とする。   In order to solve the above-described problems, the steel pillar of the present invention is formed by joining a supporting steel material having a bolt fastening tap hole to a side surface of a steel pillar body having a closed cross section without using a bolt. It is characterized by being.

上記の構成であれば、上記支持鋼材は、例えば、溶接や接着によって簡単に柱本体に接合されるので、柱の作製コストを低減することができる。また、柱自体にタップ孔を形成しないため、上記柱本体の側面間にアール部が存在する場合でも、その影響を受けずに、上記タップ孔を上記アール部に近い位置において上記支持鋼材に形成することができる。   If it is said structure, since the said support steel material is easily joined to a column main body by welding or adhesion | attachment, the production cost of a column can be reduced, for example. In addition, since no tapped hole is formed in the column itself, even if a rounded portion exists between the side surfaces of the column main body, the tapped hole is formed in the supporting steel material at a position close to the rounded portion without being affected by it. can do.

上記支持鋼材は平板形状を有しており、柱本体の側面に向けて水平方向に上記タップ孔が形成されていてもよい(以下、この項において第1構成という。)。   The support steel material has a flat plate shape, and the tap hole may be formed in the horizontal direction toward the side surface of the column main body (hereinafter referred to as a first configuration in this section).

上記支持鋼材は第1板部と第2板部とを直交させてなり、上記第1板部が鉛直配置で上記柱本体の側面に接合され、上記第2板部が水平に配置され、この第2板部に上記タップ孔が鉛直方向に形成されていてもよい(以下、この項において第2構成という。)。   The supporting steel material is formed by making the first plate portion and the second plate portion orthogonal to each other, the first plate portion is joined to the side surface of the pillar body in a vertical arrangement, and the second plate portion is arranged horizontally. The tap hole may be formed in the second plate portion in the vertical direction (hereinafter referred to as a second configuration in this section).

上記第2構成において、上記第1板部にも上記タップ孔が柱本体の側面に向けて水平方向に形成されているか、または、上記第1板部と第2板部とを有する上記支持鋼材とは別にその下方箇所に接合された第2の支持鋼材に上記タップ孔が柱本体の側面に向けて水平方向に形成されていてもよい(以下、この項において第3構成という。)。   In the second configuration, the tap steel is formed in the first plate portion in the horizontal direction toward the side surface of the column main body, or the support steel material having the first plate portion and the second plate portion. Alternatively, the tap hole may be formed in the second support steel material joined to the lower portion thereof in the horizontal direction toward the side surface of the column main body (hereinafter referred to as the third configuration in this section).

また、この発明の柱梁接合構造は、上記第1構成の鋼製柱のタップ孔に、梁のエンドプレートのボルト挿通孔に挿通されたボルトが螺合されていることを特徴とする。   The column beam connection structure of the present invention is characterized in that a bolt inserted through a bolt insertion hole of an end plate of the beam is screwed into a tap hole of the steel column having the first configuration.

また、この発明の柱梁接合構造は、上記第2構成の鋼製柱の第2板部のタップ孔に、梁のフランジのボルト挿通孔に挿通されたボルトが螺合されていることを特徴とする。   Moreover, the column beam connection structure of this invention is characterized in that a bolt inserted through a bolt insertion hole of a beam flange is screwed into a tap hole of the second plate portion of the steel column having the second configuration. And

また、この発明の柱梁接合構造は、上記第3構成の鋼製柱の第2板部のタップ孔に、梁の上フランジに挿通されたボルトが螺合され、上記水平方向に形成されたタップ孔に、梁の端の下部側に設けられた部分エンドプレートのボルト挿通孔に挿通されたボルトが螺合されていることを特徴とする。   Further, the column beam connection structure of the present invention is formed in the horizontal direction by screwing a bolt inserted into the upper flange of the beam into the tap hole of the second plate portion of the steel column having the third configuration. A bolt inserted into a bolt insertion hole of a partial end plate provided on the lower side of the end of the beam is screwed into the tap hole.

本発明であれば、柱自体にタップ孔を形成する必要がなく、また、支持鋼材を非ボルト接合で簡単に柱に接合することができる。そして、柱自体にタップ孔を形成しないため、上記柱の側面間にアール部が存在する場合でも、その影響を受けずに、上記タップ孔を上記アール部に近い位置において上記支持鋼材に形成し、上記アール部の変形を生じ難くすることができる。   If it is this invention, it is not necessary to form a tap hole in pillar itself, and support steel materials can be easily joined to a pillar by non-bolt joining. And since no tapped hole is formed in the column itself, even if a rounded portion exists between the side surfaces of the column, the tapped hole is formed in the supporting steel material at a position close to the rounded portion without being affected by it. The deformation of the rounded portion can be made difficult to occur.

以下、この発明の実施の形態を添付図面に基づいて説明する。
図1に示すように、この実施形態にかかる鋼製柱1は、閉鎖断面を有する例えば角形鋼管からなる柱本体2と、平板状の支持鋼材3とを備えている。上記柱本体2は4つの側面を有しており、側面間にはアール部2aが存在している。また、この例では、上記柱本体2の隣り合う2面が仕口面とされ、この仕口面にのみ上記支持鋼材3が設けられる。上記支持鋼材3は各仕口面において上下に2枚設けられており、各支持鋼材3には、4個のボルト締結用のタップ孔3aが、柱本体2の側面に直交するように水平方向に形成されている。一例として、上記支持鋼材3の厚さおよび上記タップ孔3aの深さは28mmとされ、このタップ孔3aの深さの略全体を使ってボルトの螺子部が入り込むようにしている。また、上記支持鋼材3の幅は上記柱本体2の幅と同程度とされる。
Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the steel pillar 1 concerning this embodiment is provided with the pillar main body 2 which consists of a square steel pipe which has a closed cross section, and the flat support steel material 3, for example. The column body 2 has four side surfaces, and a rounded portion 2a exists between the side surfaces. Further, in this example, two adjacent surfaces of the column main body 2 are used as a joint surface, and the support steel material 3 is provided only on the joint surface. The support steel material 3 is provided in two on the top and bottom of each joint surface, and each support steel material 3 has four tap holes 3a for fastening bolts in the horizontal direction so as to be orthogonal to the side surface of the column body 2. Is formed. As an example, the thickness of the support steel material 3 and the depth of the tap hole 3a are 28 mm, and the screw portion of the bolt is inserted by using substantially the entire depth of the tap hole 3a. The width of the support steel material 3 is approximately the same as the width of the column main body 2.

また、上記支持鋼材3はボルトを用いずに上記仕口面に接合される。このボルトを用いない接合には、接着剤による接着および溶接がある。この例では、溶接による接合を行っている。一例として、図2(A)に示すように、上記支持鋼材3は上記柱本体2の側面に隅肉溶接される。また、上記柱本体2の隣り合う2側面が仕口面とされる場合、図2(B)に示すように、1つの仕口面においては隅肉溶接が行われ、他の仕口面においては、開先を形成した溶接が行われる。もちろん、1つの仕口面にのみ上記支持鋼材3が溶接される場合でも、開先溶接が行われてもよいし、また、開先溶接と隅肉溶接を適宜に混在させることもできる。これらの溶接により、上記アール部2aの箇所で力の伝達が的確に行われるようになる。上記鋼製柱1は、工場で作製されて施工現場に搬送される。   Moreover, the said support steel material 3 is joined to the said joint surface, without using a volt | bolt. Bonding without using bolts includes bonding with an adhesive and welding. In this example, welding is performed. As an example, as shown in FIG. 2A, the support steel material 3 is fillet welded to the side surface of the column main body 2. In addition, when two adjacent side surfaces of the column main body 2 are used as a joint surface, as shown in FIG. 2B, fillet welding is performed on one joint surface, and on the other joint surface, The welding which formed the groove | channel is performed. Of course, even when the support steel material 3 is welded to only one joint surface, groove welding may be performed, and groove welding and fillet welding can be mixed appropriately. By these weldings, the force is accurately transmitted at the rounded portion 2a. The said steel pillar 1 is produced in a factory, and is conveyed to a construction site.

施工現場では、図3(A)、図3(B)および図4に示すように、上記支持鋼材3に梁4におけるエンドプレート41が固定されることで、一実施形態となる柱梁接合構造が構築される。上記エンドプレート41には、例えば8個のボルト挿通孔41aが形成されており、このボルト挿通孔41aにボルト5が挿通され、このボルト5の螺子部が上記支持鋼材3のタップ孔3aに螺合される。上記ボルト5としては、例えば、ピンテール付き両ネジボルトが用いられる。上記ピンテールは、規定トルクによる上記ボルト5の締め付け時に、自動切断される。   At the construction site, as shown in FIG. 3 (A), FIG. 3 (B) and FIG. 4, the end plate 41 in the beam 4 is fixed to the support steel material 3, so that the column beam connection structure which is an embodiment. Is built. For example, eight bolt insertion holes 41 a are formed in the end plate 41, and bolts 5 are inserted into the bolt insertion holes 41 a, and screw portions of the bolts 5 are screwed into the tap holes 3 a of the support steel material 3. Combined. As the bolt 5, for example, a double screw bolt with a pin tail is used. The pin tail is automatically cut when the bolt 5 is tightened with a specified torque.

上記の構成であれば、上記支持鋼材3はボルトを用いずに溶接によって柱本体2に設けられるので、作製コスト等を低減することができる。また、柱自体にタップ孔を形成しないため、上記柱本体2の側面間にアール部2aが存在する場合でも、その影響を受けずに、上記タップ孔3aを上記アール部に近い位置において上記支持鋼材3に形成することができる。もちろん、鋼製柱1は、柱本体にアール部が形成されない構造にも用いることができる。   If it is said structure, since the said supporting steel material 3 is provided in the column main body 2 by welding, without using a volt | bolt, production costs etc. can be reduced. In addition, since the tap hole is not formed in the column itself, even if the rounded portion 2a exists between the side surfaces of the column main body 2, the tap hole 3a is supported at a position close to the rounded portion without being affected by the rounded portion 2a. The steel material 3 can be formed. Of course, the steel pillar 1 can also be used in a structure in which the rounded portion is not formed on the pillar body.

また、上記支持鋼材3を上下に2枚設けると、図5(A)および図5(B)に示すように、上記鋼製柱1に対して高さ(梁せい)の異なる2本の梁4が段違いで接続される場合でも、上記2枚の支持鋼材3の配置間隔を異ならせるだけで簡単に対応することができる。また、このように上記支持鋼材3を2枚に分割して設けると、溶接個所が増えるため、上記柱本体2に対する支持鋼材3の固定強度を高めることができる。   When two support steel materials 3 are provided on the upper and lower sides, as shown in FIGS. 5 (A) and 5 (B), two beams having different heights (beams) from the steel column 1 are provided. Even when 4 are connected in different steps, it is possible to easily cope with this by simply changing the arrangement interval of the two support steel materials 3. In addition, when the support steel material 3 is divided and provided in this way, the number of welding points increases, so that the fixing strength of the support steel material 3 with respect to the column main body 2 can be increased.

なお、上記支持鋼材3を2枚分割としない1枚構成を採用する場合には、上記利点は得られないものの、タップ孔3aの形成位置の精度を高めることができる等の利点が得られることになる。   In addition, when adopting a one-piece configuration in which the support steel material 3 is not divided into two pieces, the above advantage cannot be obtained, but the advantage that the accuracy of the formation position of the tap hole 3a can be increased. become.

次に、他の実施形態について説明していく。図6に示すように、この実施形態の鋼製柱1Aでは、仕口面となる側面に支持鋼材3Aが上下に2個設けられている。各支持鋼材3Aは、第1板部31と第2板部32とが直交するL字形状を有している。各支持鋼材3Aの上記第1板部31は、鉛直配置で上記柱本体2の側面に溶接により接合されている。また、上側の支持鋼材3Aはその第2板部32を上側に水平に位置させており、下側の支持鋼材3Aはその第2板部32を下側に水平に位置させている。上下の第2板部32の間隔は梁4の高さ(梁せい)に合致している。各第2板部32には、上記タップ孔3aが鉛直方向に形成されている。   Next, other embodiments will be described. As shown in FIG. 6, in the steel column 1 </ b> A of this embodiment, two support steel materials 3 </ b> A are provided on the upper and lower sides on the side surface serving as the joint surface. Each supporting steel material 3A has an L shape in which the first plate portion 31 and the second plate portion 32 are orthogonal to each other. The first plate portion 31 of each supporting steel material 3A is joined to the side surface of the column main body 2 by welding in a vertical arrangement. Further, the upper support steel material 3A has the second plate portion 32 horizontally positioned on the upper side, and the lower support steel material 3A has the second plate portion 32 horizontally positioned on the lower side. The distance between the upper and lower second plate portions 32 matches the height of the beam 4 (beam beam). Each of the second plate portions 32 has the tap hole 3a formed in the vertical direction.

上記鋼製柱1Aを用いた梁柱接合構造においては、上記梁4においては、エンドプレート41は設けられておらず、上下のフランジ42の端側にボルト挿通孔42aが鉛直方向に形成されている。そして、上記支持鋼材3Aの第2板部32のタップ孔3aに、上記フランジ42のボルト挿通孔42aに挿通されたボルト5が螺合される。   In the beam-column connection structure using the steel column 1A, the beam 4 is not provided with the end plate 41, and the bolt insertion hole 42a is formed in the vertical direction on the end side of the upper and lower flanges 42. Yes. Then, the bolt 5 inserted through the bolt insertion hole 42a of the flange 42 is screwed into the tap hole 3a of the second plate portion 32 of the support steel material 3A.

このような構成においても、柱自体の加工を必要とせず、上記支持鋼材3Aはボルトを用いずに溶接によって柱本体2に設けられるので、上記鋼製柱1Aの作製コスト等を低減することができる。   Even in such a configuration, it is not necessary to process the column itself, and the support steel material 3A is provided on the column main body 2 by welding without using a bolt, so that the manufacturing cost and the like of the steel column 1A can be reduced. it can.

次に、他の実施形態について説明していく。図7に示すように、この実施形態の鋼製柱1Bでは、仕口面となる側面に上記支持鋼材3Aと第2の支持鋼材30が上下に1個ずつ設けられている。上記第2の支持鋼材30は、上記支持鋼材3と同一の構成としているが、これに限らない。上記第2の支持鋼材30および上記支持鋼材3Aの上記第1板部31は、鉛直配置で上記柱本体2の側面に溶接により接合されている。また、上記支持鋼材3Aの第2板部32は上側において水平に位置されている。   Next, other embodiments will be described. As shown in FIG. 7, in the steel column 1 </ b> B of this embodiment, the support steel material 3 </ b> A and the second support steel material 30 are provided one above the other on the side surface serving as the joint surface. Although the said 2nd support steel material 30 is taken as the same structure as the said support steel material 3, it is not restricted to this. The second support steel material 30 and the first plate portion 31 of the support steel material 3A are joined to the side surface of the column body 2 by welding in a vertical arrangement. The second plate portion 32 of the support steel material 3A is positioned horizontally on the upper side.

上記鋼製柱1Bを用いた梁柱接合構造においては、上記梁4には、下側半分において部分エンドプレート41Aが設けられている。そして、この部分エンドプレート41Aに設けられたボルト挿通孔41aに通されたボルト5が上記支持鋼材3のタップ孔3aに螺合される。また、上側のフランジ42の端側にボルト挿通孔42aが鉛直方向に形成されており、上記支持鋼材3Aの第2板部32のタップ孔3aに、上記ボルト挿通孔42aから挿通されたボルト5が螺合される。   In the beam-column connection structure using the steel column 1B, the beam 4 is provided with a partial end plate 41A in the lower half. Then, the bolt 5 passed through the bolt insertion hole 41 a provided in the partial end plate 41 A is screwed into the tap hole 3 a of the support steel material 3.

Cost and the like can be reduced. Further, regarding the joining of the second supporting steel material 30, since the tap hole is not formed in the column itself, even if the round portion 2 a exists between the side surfaces of the column main body 2, the tap is not affected by the tap portion. The hole 3a can be formed in the support steel material 3 at a position close to the rounded portion.

また、上記支持鋼材3Aの第2板部32が上側で水平配置されると、例えば、ALC等の床版を配置するときに、この床版の側面を柱本体2の側面に接するように配置することが容易になる。なお、上記ボルト5については、その先端が上記第2板部32の上面から突出しないようにしている。また、上記第2の支持鋼材30を省略する一方で上記支持鋼材3Aの第1板部31の長さを長くし、この長くされた第1板部31にタップ孔3aを形成するようにしてもよい。   Further, when the second plate portion 32 of the support steel material 3A is horizontally disposed on the upper side, for example, when a floor slab such as ALC is disposed, the side surface of the floor slab is disposed so as to contact the side surface of the column body 2 Easy to do. It should be noted that the front end of the bolt 5 does not protrude from the upper surface of the second plate portion 32. Further, while omitting the second support steel material 30, the length of the first plate portion 31 of the support steel material 3 </ b> A is lengthened, and the tap hole 3 a is formed in the lengthened first plate portion 31. Also good.

次に、他の実施形態について説明していく。図8に示すように、この実施形態の鋼製柱1Cでは、仕口面となる側面に支持鋼材3Bが上下に2個設けられている。各支持鋼材3Bは、第1板部31と第2板部32とが直交するT字形状を有している。各支持鋼材3Bの上記第1板部31は、鉛直配置で上記柱本体2の側面に溶接により接合されており、上記第2板部32は水平に位置されている。上下の第2板部32の間隔は梁4の高さ(梁せい)に合致する。上記第2板部32には、上記タップ孔3aが鉛直方向に形成されている。   Next, other embodiments will be described.
