Description

本発明は、一方の形鋼の端部と他方の形鋼の端部とを接合する方法に関する。   The present invention relates to a method of joining an end of one section and an end of the other section.

従来、一方のＨ形鋼の端部と他方のＨ形鋼の端部とを接合する方法としては、添え板と高力ボルトとを用いた周知の接合方法や、一方のＨ形鋼の端部と他方のＨ形鋼の端部とが挿入される貫通孔とねじ溝付ボルト孔とを備えた接続金具を用いて貫通孔に挿入されたＨ形鋼の端部をねじ溝付ボルト孔に螺着されるボルトで固定する接合方法（特許文献１参照）等が知られている。   Conventionally, as a method of joining the end of one H-section steel and the end of the other H-section steel, a well-known joining method using a splicing plate and a high-strength bolt, or the end of one H-section steel The end portion of the H-shaped steel inserted into the through-hole using the connection fitting provided with the through-hole into which the end portion and the other H-shaped steel end portion are inserted and a threaded groove bolt hole is used as the screw grooved bolt hole. There is known a joining method (see Patent Document 1) for fixing with a bolt that is screwed onto the joint.

しかしながら、形鋼としてのＨ形鋼同士を上述した接合方法により接合した場合、ボルトによる接合であるため、滑動面がなく、滑動面の摩擦によって振動エネルギーを吸収できる構成とはなっていないので、Ｈ形鋼の振動を抑制できないという課題があった。例えば梁として使用されるＨ形鋼同士を上述した接合方法により接合した場合、人の歩行時の床振動を抑制できない。
本発明は、形鋼の振動を抑制できる形鋼の接合方法を提供する。 However, when the H-shaped steels as the shape steel are joined together by the joining method described above, there is no sliding surface because it is a joining by bolt, and it is not configured to absorb vibration energy by friction of the sliding surface. There was a problem that the vibration of the H-shaped steel could not be suppressed. For example, when H-shaped steels used as beams are joined together by the joining method described above, floor vibrations during human walking cannot be suppressed.
The present invention provides a method for joining shaped steels that can suppress vibrations of the shaped steels.

本発明に係る形鋼の接合方法は、一方の形鋼の端部及び他方の形鋼の端部を、当該形鋼の断面形状に対応した断面形状の筒状内面を有した管体の当該筒状内面に嵌合させて、当該管体の筒状内面と一方の形鋼の端部との摩擦力及び当該管体の筒状内面と他方の形鋼の端部との摩擦力によって、一方の形鋼と他方の形鋼とを接合したことを特徴とするので、形鋼と管体の筒状内面とが嵌合された滑動面同士が滑動する際の摩擦によって一方の形鋼及び他方の形鋼の振動エネルギーが吸収され、一方の形鋼と他方の形鋼との接合部の減衰性能が増すので、形鋼の振動を抑制できる。
また、形鋼がＨ形鋼であり、当該Ｈ形鋼は、Ｈ形鋼の長手方向の端部における一対のフランジの外表面がＨ形鋼の長手方向の延長端に近付くほど互いに近づく傾斜面に形成されており、管体は、両端開口側に、Ｈ形鋼の長手方向の端部におけるフランジの傾斜面に嵌合する筒状内面を有しており、一方のＨ形鋼の長手方向の端部におけるフランジの傾斜面と管体の一方の開口側の筒状内面とを嵌合させるとともに、他方のＨ形鋼の長手方向の端部におけるフランジの傾斜面と管体の他方の開口側の筒状内面とを嵌合させることによって、一方のＨ形鋼と他方のＨ形鋼とを接合したことを特徴とするので、Ｈ形鋼の長手方向の端部を管体の筒状内面に挿入しやすくなって、Ｈ形鋼の長手方向の端部と管体の筒状内面とを簡単に嵌合させることができるようになるとともに、Ｈ形鋼と管体の筒状内面とが嵌合された滑動面同士が滑動する際の摩擦によって一方のＨ形鋼及び他方のＨ形鋼の振動エネルギーが吸収され、一方のＨ形鋼と他方のＨ形鋼との接合部の減衰性能が増すので、Ｈ形鋼の振動を抑制できる。
また、形鋼がＨ形鋼であり、当該Ｈ形鋼は、Ｈ形鋼の長手方向の端部におけるウェブの少なくとも一方の表面がＨ形鋼の延長端に近付くほどウェブの他方の表面に近づく傾斜面に形成されており、管体は、両端開口側に、Ｈ形鋼の長手方向の端部におけるウェブの傾斜面に嵌合する筒状内面を有しており、一方のＨ形鋼の長手方向の端部におけるウェブの傾斜面と管体の一方の開口側の筒状内面とを嵌合させるとともに、他方のＨ形鋼の長手方向の端部におけるウェブの傾斜面と管体の他方の開口側の筒状内面とを嵌合させることによって、一方のＨ形鋼と他方のＨ形鋼とを接合したことを特徴とするので、Ｈ形鋼の長手方向の端部を管体の筒状内面に挿入しやすくなって、Ｈ形鋼の長手方向の端部と管体の筒状内面とを簡単に嵌合させることができるようになるとともに、Ｈ形鋼と管体の筒状内面とが嵌合された滑動面同士が滑動する際の摩擦によって一方のＨ形鋼及び他方のＨ形鋼の振動エネルギーが吸収され、一方のＨ形鋼と他方のＨ形鋼との接合部の減衰性能が増すので、Ｈ形鋼の振動を抑制できる。
また、形鋼がＨ形鋼であり、管体は、Ｈ形鋼の長手方向の端部における一対のフランジの外表面の半分及びＨ形鋼の長手方向の端部におけるウェブの外表面の半分に嵌合する内面を有した一対の半割ピースを組み合わせることにより構成され、一方の半割ピースの内面を、一方のＨ形鋼の長手方向の端部における外表面の一方の半分及び他方のＨ形鋼の長手方向の端部における外表面の一方の半分に嵌合させるとともに、他方の半割ピースの内面を、一方のＨ形鋼の長手方向の端部における外表面の他方の半分及び他方のＨ形鋼の長手方向の端部における外表面の他方の半分に嵌合させた状態で、一方の半割ピースと他方の半割ピースとを接続することにより、一方のＨ形鋼と他方のＨ形鋼とを接合したことを特徴とするので、一方のＨ形鋼及び他方のＨ形鋼における長手方向と直交する方向における一方側及び他方側からそれぞれ半割ピースを一方のＨ形鋼の端部及び他方のＨ形鋼の端部に簡単に嵌合させることができるようになるとともに、Ｈ形鋼と半割ピースとが嵌合された滑動面同士が滑動する際の摩擦によって一方のＨ形鋼及び他方のＨ形鋼の振動エネルギーが吸収され、一方のＨ形鋼と他方のＨ形鋼との接合部の減衰性能が増すので、Ｈ形鋼の振動を抑制できる。
また、Ｈ形鋼は、フランジの外表面が傾斜面に形成されており、当該傾斜面は、フランジの外表面におけるＨ形鋼の長手方向と直交する方向における中央側から端側に向けて互いに近づくように傾斜する傾斜面に形成されており、半割ピースは、傾斜面に形成されたフランジの外表面に嵌合する傾斜内面を備えており、傾斜面に形成されたフランジの外表面と半割ピースの傾斜内面とを嵌合させたことを特徴とするので、一方のＨ形鋼及び他方のＨ形鋼における長手方向と直交する方向における一方側及び他方側からそれぞれ半割ピースを一方のＨ形鋼の端部及び他方のＨ形鋼の端部により簡単に嵌合させることができるようになるとともに、Ｈ形鋼と半割ピースとが嵌合された滑動面同士が滑動する際の摩擦によって一方のＨ形鋼及び他方のＨ形鋼の振動エネルギーが吸収され、一方のＨ形鋼と他方のＨ形鋼との接合部の減衰性能が増すので、Ｈ形鋼の振動を抑制できる。 In the method for joining shaped steels according to the present invention, the end of one shaped steel and the edge of the other shaped steel are connected to the tubular body having a cylindrical inner surface having a cross-sectional shape corresponding to the cross-sectional shape of the shaped steel. By fitting to the cylindrical inner surface, the frictional force between the cylindrical inner surface of the tubular body and the end of one shape steel and the frictional force between the cylindrical inner surface of the tubular body and the end of the other structural steel, Since one shape steel and the other shape steel are joined, the shape steel and the tubular inner surface of the tubular body are fitted to each other. The vibration energy of the other structural steel is absorbed and the damping performance of the joint between one structural steel and the other structural steel increases, so that the vibration of the structural steel can be suppressed.
Further, the section steel is an H-section steel, and the H-section steel is inclined surfaces that approach each other as the outer surfaces of a pair of flanges at the end portions in the longitudinal direction of the H-section steel approach the extension ends in the longitudinal direction of the H-section steel. The tubular body has a cylindrical inner surface that is fitted to the inclined surface of the flange at the end in the longitudinal direction of the H-shaped steel on both end opening sides, and the longitudinal direction of one H-shaped steel The inclined surface of the flange at the end of the tube and the cylindrical inner surface on the one opening side of the tubular body are fitted together, and the inclined surface of the flange and the other opening of the tubular body at the longitudinal end of the other H-shaped steel Since one H-section steel and the other H-section steel are joined by fitting the cylindrical inner surface on the side, the end in the longitudinal direction of the H-section steel is the tubular shape of the tubular body. It becomes easy to insert into the inner surface, and the end in the longitudinal direction of the H-section steel and the tubular inner surface of the tube can be easily fitted The vibration energy of one H-section steel and the other H-section steel is absorbed by the friction generated when the sliding surfaces fitted with the H-section steel and the tubular inner surface of the tubular body slide. Since the damping performance of the joint between one H-section steel and the other H-section steel increases, vibration of the H-section steel can be suppressed.
Further, the section steel is an H-section steel, and the H-section steel approaches the other surface of the web so that at least one surface of the web at the end portion in the longitudinal direction of the H-section steel approaches the extension end of the H-section steel. The tubular body has a cylindrical inner surface that fits the inclined surface of the web at the longitudinal end portion of the H-shaped steel on both end opening sides, The inclined surface of the web at the end portion in the longitudinal direction and the cylindrical inner surface on the one opening side of the tubular body are fitted, and the inclined surface of the web at the longitudinal end portion of the other H-section steel and the other of the tubular body Since one H-section steel and the other H-section steel are joined by fitting the cylindrical inner surface on the opening side of the tube, the longitudinal end of the H-section steel is connected to the tube body. It is easy to insert into the cylindrical inner surface, and the end in the longitudinal direction of the H-section steel and the cylindrical inner surface of the tube can be easily fitted. In addition, the vibration energy of one H-section steel and the other H-section steel is absorbed by the friction generated when the sliding surfaces in which the H-section steel and the cylindrical inner surface of the tubular body are slid. Since the damping performance of the joint between one H-section steel and the other H-section steel increases, vibration of the H-section steel can be suppressed.
Further, the shape steel is H-section steel, and the pipe body is half of the outer surface of the pair of flanges at the longitudinal end of the H-section steel and half of the outer surface of the web at the longitudinal end of the H-section steel. A pair of half pieces having an inner surface that fits into the inner surface, and the inner surface of one half piece is connected to one half of the outer surface at the longitudinal end of one H-section steel and the other Fitting one half of the outer surface at the longitudinal end of the H-section steel and the other half piece with the other half of the outer surface at the longitudinal end of one H-section and By connecting one half piece and the other half piece in a state of being fitted to the other half of the outer surface at the longitudinal end of the other H shape steel, Because it is characterized by joining the other H-section steel, one H-section steel In addition, the half piece can be easily fitted to the end of one H-section steel and the end of the other H-section steel from one side and the other side in the direction perpendicular to the longitudinal direction of the other H-section steel. The vibration energy of one H-section steel and the other H-section steel is absorbed by the friction generated when the sliding surfaces into which the H-section steel and the half piece are fitted slide. Since the damping performance of the joint between the shape steel and the other H-shape steel is increased, the vibration of the H-shape steel can be suppressed.
Moreover, the outer surface of a flange is formed in the inclined surface as for the H-section steel, and the said inclined surface mutually is toward the end side from the center side in the direction orthogonal to the longitudinal direction of the H-section steel in the outer surface of a flange. The halved piece is provided with an inclined inner surface that fits to the outer surface of the flange formed on the inclined surface, and has an outer surface of the flange formed on the inclined surface. Since the inclined inner surface of the half piece is fitted, one half piece from one side and the other side in the direction orthogonal to the longitudinal direction of one H-section steel and the other H-section steel When the H-section steel end and the other H-section end can be easily fitted together, and the sliding surfaces fitted with the H-section steel and the half piece slide together. One H-section steel and the other by friction Is vibration energy absorption of H-shaped steel, since damping performance of the joint portion between one H-section steel and the other H-shaped steel is increased, it is possible to suppress the vibration of the H-shaped steel.

実施形態１
実施形態１に係る形鋼の接合方法は、図２，図３に示すように、形鋼としてのＨ形鋼１の断面形状に対応した断面形状の筒状内面２を有した管体３を用い、一方のＨ形鋼１Ａ（１）の端部１０Ａと管体３の一方の開口３０Ａ側の筒状内面２とを嵌合させるとともに、他方のＨ形鋼１Ｂ（１）の端部１０Ｂと管体３の他方の開口３０Ｂ側の筒状内面２とを嵌合させて、当該管体３と一方のＨ形鋼１Ａの端部１０Ａとの摩擦力及び当該管体３と他方のＨ形鋼１Ｂの端部１０Ｂとの摩擦力によって、一方のＨ形鋼１Ａと他方のＨ形鋼１Ｂとを接合する方法である。 Embodiment 1
As shown in FIGS. 2 and 3, the method for joining section steels according to Embodiment 1 includes a tubular body 3 having a cylindrical inner surface 2 having a cross-sectional shape corresponding to the cross-sectional shape of H-section steel 1 as a section steel. Used, the end 10A of one H-section steel 1A (1) and the cylindrical inner surface 2 on the one opening 30A side of the tube 3 are fitted together, and the end 10B of the other H-section steel 1B (1) is used. And the tubular inner surface 2 on the other opening 30B side of the tubular body 3 are fitted, and the frictional force between the tubular body 3 and the end portion 10A of one H-shaped steel 1A and the tubular body 3 and the other H This is a method of joining one H-section steel 1A and the other H-section steel 1B by frictional force with the end 10B of the section steel 1B.

即ち、一方のＨ形鋼１Ａの端部１０Ａ及び他方のＨ形鋼１Ｂの端部１０Ｂを、当該Ｈ形鋼１の断面形状に対応した断面形状の筒状内面２を有した管体３の当該筒状内面２に嵌合させて、当該管体３の筒状内面２と一方のＨ形鋼１Ａの端部１０Ａとの摩擦力及び当該管体３の筒状内面２と他方のＨ形鋼１Ｂの端部１０Ｂとの摩擦力によって、一方のＨ形鋼１Ａと他方のＨ形鋼１Ｂとを接合する。つまり、当該Ｈ形鋼の接合方法によって接合されたＨ形鋼の接合構造は、一方のＨ形鋼１Ａの端部１０Ａと管体３の一方の開口３０Ａ側の筒状内面２とが嵌合状態となり、かつ、他方のＨ形鋼１Ｂの端部１０Ｂと管体３の他方の開口３０Ｂ側の筒状内面２とが嵌合状態となっている。   That is, the end portion 10A of one H-section steel 1A and the end portion 10B of the other H-section steel 1B are formed of a tubular body 3 having a cylindrical inner surface 2 having a cross-sectional shape corresponding to the cross-sectional shape of the H-section steel 1. Fitting between the tubular inner surface 2 and the frictional force between the tubular inner surface 2 of the tubular body 3 and the end portion 10A of one H-shaped steel 1A, and the tubular inner surface 2 of the tubular body 3 and the other H-shape. One H-section steel 1A and the other H-section steel 1B are joined by a frictional force with the end portion 10B of the steel 1B. In other words, in the H-section steel joined structure joined by the H-section steel joining method, the end 10A of one H-section steel 1A and the cylindrical inner surface 2 on the one opening 30A side of the tube 3 are fitted. The end portion 10B of the other H-section steel 1B and the tubular inner surface 2 on the other opening 30B side of the tube body 3 are in a fitted state.

Ｈ形鋼１は、長尺鋼材を圧延機で圧延することにより断面Ｈ形状に製造されたものであり、「Ｈ」の縦板部である一対のフランジ１２，１３と「Ｈ」の横板部であるウェブ１４とを備えた構成である。尚、Ｈ形鋼１を梁として使用する場合、フランジ１２，１３が上下に位置される状態に取付けられるので、以後、梁として使用される場合に、上側に位置されるフランジを上フランジ１２、下側に位置されるフランジを下フランジ１３という。
そして、管体３の筒状内面２は、上下のフランジ１２，１３の表面に嵌合されるフランジ対応内面２２，２３と、ウェブ１４の表面に嵌合されるウェブ対応内面２４とを有した断面Ｈ形状の筒状内面である。
管体３は、例えば成形型により製造された金属製の管体により構成される。 The H-section steel 1 is manufactured by rolling a long steel material with a rolling mill into an H-shaped cross section, and a pair of flanges 12 and 13 which are vertical plate portions of “H” and a horizontal plate of “H”. It is the structure provided with the web 14 which is a part. When the H-shaped steel 1 is used as a beam, the flanges 12 and 13 are mounted in a vertically positioned state. Therefore, when used as a beam, the upper flange 12 The flange located on the lower side is referred to as a lower flange 13.
The tubular inner surface 2 of the tubular body 3 has flange-corresponding inner surfaces 22 and 23 fitted to the surfaces of the upper and lower flanges 12 and 13 and a web-corresponding inner surface 24 fitted to the surface of the web 14. It is a cylindrical inner surface having an H-shaped cross section.
The tubular body 3 is constituted by a metallic tubular body manufactured by a mold, for example.

実施形態１に係るＨ形鋼の接合方法によって接合されたＨ形鋼の接合構造によれば、一方のＨ形鋼１Ａの端部１０Ａと管体３の一方の開口３０Ａ側の筒状内面２との接触界面の摩擦力及び他方のＨ形鋼１Ｂの端部１０Ｂと管体３の他方の開口３０Ｂ側の筒状内面２との接触界面の摩擦力、即ち、Ｈ形鋼１Ａ，１Ｂと管体３の筒状内面２とが嵌合された滑動面同士が滑動する際の摩擦によってＨ形鋼１Ａ，１Ｂの振動エネルギーが吸収され、一方のＨ形鋼１Ａと他方のＨ形鋼１Ｂとの接合部の減衰性能が増すので、Ｈ形鋼１Ａ，１Ｂの振動を抑制できるようになる。   According to the joining structure of the H-section steel joined by the joining method of the H-section steel according to the first embodiment, the cylindrical inner surface 2 on the one opening 30A side of the end portion 10A of the one H-section steel 1A and the tubular body 3. And the friction force at the contact interface between the end portion 10B of the other H-shaped steel 1B and the cylindrical inner surface 2 on the other opening 30B side of the tubular body 3, that is, the H-shaped steels 1A and 1B The vibration energy of the H-section steels 1A and 1B is absorbed by the friction generated when the sliding surfaces fitted with the cylindrical inner surface 2 of the tube body 3 slide, so that one H-section steel 1A and the other H-section steel 1B. Therefore, the vibration of the H-section steels 1A and 1B can be suppressed.

そして、上述したＨ形鋼の接合方法により、例えば、図１に示すように、２本以上のＨ形鋼１，１…が接合された大梁１００を形成し、当該大梁１００を鉄骨柱１０１に接合した大スパン鉄骨造架構２００を構築した場合、Ｈ形鋼１Ａ，１Ｂの振動を抑制できて、人の歩行時の床振動を低減できる大スパン鉄骨造架構２００を得ることができるようになる。
この場合、例えば、工場にて、一方のＨ形鋼１Ａ（１）の端部１０Ａを管体３の一方の開口３０Ａ側から筒状内面２に圧入するとともに、他方のＨ形鋼１Ｂ（１）の端部１０Ｂを管体３の他方の開口３１側から筒状内面２に圧入することによって、大スパン鉄骨造架構２００を形成し、当該大スパン鉄骨造架構２００を建築現場に搬入して当該大スパン鉄骨造架構２００の両端を鉄骨柱１０１に溶接等で接合したり、予め鉄骨柱１０１に溶接等で接合しておいた図外の梁と当該大スパン鉄骨造架構２００の両端とを従来のような添え板と高力ボルトとを用いて接合する。 Then, by the above-described H-section steel joining method, for example, as shown in FIG. 1, a large beam 100 in which two or more H-section steels 1, 1... Are joined is formed. When the joined large-span steel frame 200 is constructed, it is possible to obtain the large-span steel frame 200 that can suppress the vibrations of the H-shaped steels 1A and 1B and reduce the floor vibration during walking of a person. .
In this case, for example, at the factory, the end portion 10A of one H-section steel 1A (1) is press-fitted into the cylindrical inner surface 2 from the one opening 30A side of the tubular body 3, and the other H-section steel 1B (1 ) Is pressed into the cylindrical inner surface 2 from the other opening 31 side of the tubular body 3 to form a large span steel frame structure 200, and the large span steel frame structure 200 is carried into the construction site. Both ends of the large-span steel frame structure 200 are joined to the steel column 101 by welding or the like, and the unillustrated beam and the both ends of the large-span steel frame structure 200 previously joined to the steel column 101 by welding or the like. It joins using a conventional attachment plate and a high strength bolt.
