Description

【0001】
【発明の属する技術分野】
本発明は、例えば、鋼構造建築物を構築する際に、H形断面柱または箱形断面柱とH形断面梁の高力ボルト摩擦接合構造、またはH形断面梁とH形断面梁との高力ボルト摩擦接合構造において適用される、高力ボルト摩擦接合構造に関するものである。
【0002】
【従来の技術】
近年、箱形断面柱とH形断面梁を用いた両方向ラーメン構造が多用されており、接合構造としては図9(a)〜(c)で示すような通しダイアフラム形式の接合構造が用いられている。この形式の接合構造では、箱形断面柱1と上下のダイアフラム2a、2bとコラムコア2cの接合、ダイアフラム2と梁取付部3の接合は溶接wによって行われ、梁取付部3とH形断面梁4は、双方のフランジ3a、3bと4a、4b間では外側と内側の添板5aと5b、5cを介して、また、双方のウエブ3uと4u間では左右一対の添板6aと6bを介して、それぞれ高力ボルト7によって接合されていた。
【0003】
また、最近では、図10(a)〜(c)で示すように、ダイアフラムや梁取付部を用いずに箱形断面柱1に上下一対のスプリットティ8a、8bのフランジ8fを高力ボルト9で接合し、この上下一対のスプリットティ8a、8bの水平ウエブ8uにH形断面梁4の上下フランジ4a、4bを高力ボルト10で接合することにより、溶接負担を軽減する接合構造が採用されるようになってきている。
【0004】
このような接合構造において、例えば中小規模の地震から大地震に至るまでの広範囲に対応可能な耐力を確保するために、エネルギー吸収機能を有する摩擦ダンパーの使用が試みられている。摩擦ダンパーは、剛塑性変形の履歴特性を示す履歴減衰ダンパーであり、荷重変形曲線がループを描くことを利用して振動の減衰を図ろうとするもので、そのヒステリシスループの面積が一周期の間に吸収するエネルギーに相当する。
このような摩擦ダンパーの一例として、摩擦板材と滑り板材とを高力ボルトで挟圧し、両板間に発生する摩擦力によりダンパー機能を発揮させるようにした、比較的廉価に製造できるとともに保守点検も簡便な摩擦接合式エネルギー吸収構造が知られている。
【0005】
この摩擦接合式エネルギー吸収構造は、例えば、特開平11−190147号公報に示すように、2枚の摩擦板とそれらに挟まれた1枚の滑り板材とからなっており、摩擦板は、一方の接合部材に高力ボルト接合され、相対的に変位することができない板材で、通常のボルト孔を有するものである。
一方、滑り板は、他方の接合部材側に通常のボルト孔を有し通常の高力ボルト接合されており、一方の接合部材側に高力ボルトを挿通した状態で、高力ボルトに対して変位可能とするための長手方向に延びるスロットホール(ボルト孔)を有するものである。
【0006】
この摩擦接合式エネルギー吸収構造に引張力が作用した場合、摩擦板と滑り板に生じる摩擦力を超えた場合には、滑り板は高力ボルトの軸部がスロットホールの一方の壁に突き当たるまで移動することができる。また、圧縮力が作用した場合には、高力ボルトの軸部がスロットホールの他方の壁に突き当たるまで移動することができる。
したがって、滑り板は、摩擦板との間に引張力、圧縮力が摩擦力を超えて作用した場合、スロットホールの長さから高力ボルトの軸径を差し引いた長さを最大として伸縮移動が可能であることから、スロットホールの寸法選定によっては、中小の地震から大地震までのエネルギーを吸収させることが可能になる利点がある。
【0007】
このような、摩擦接合式エネルギー吸収構造を、例えば、前記した箱形断面柱とH形断面梁の高力ボルト摩擦接合構造や、H形断面材とH形断面材の高力ボルト摩擦接合構造に適用できるが、必要な接合構造の耐力を確保するためには、摩擦面を増やさなければならないため、摩擦板材と滑り板材の枚数増加が余儀なくされ、接合構造が複雑となり施工負担の増大に加え材料コストが増大するという問題がある。
【0008】
【発明が解決しようとする課題】
本発明は、上記した問題に鑑みてなされたもので、接合対象の相対するH形断面材の高力ボルト摩擦接合構造、箱形断面柱とH形断面梁の高力ボルト摩擦接合構造において、摩擦板材や滑り板材を少なくしても摩擦面を多く確保でき、これによって小型かつ安価なダンパーでありながら中小規模の地震から大地震に至るまでの広範囲に対応可能な耐力を備えることができるエネルギー吸収機能を有する摩擦ダンパーを備えたH形断面材または箱形断面柱とH形断面梁の高力ボルト摩擦接合構造を提供するものである。

【0013】
【発明の実施の形態】
本発明は、例えば、箱型断面柱に取り付けたH形断面材またはスプリットティに、H形断面梁を突き合わせるように配置して、H形断面材またはスプリットティとH形断面梁に跨がって当接された添板やジョイントアングルを介してH形断面梁を高力ボルト摩擦接合する場合、あるいはH形断面材とH形断面材を添板または添板とジョイントアングルを介して高力ボルト摩擦接合する場合において、主に適用されるものであり、添板やジョイントアングルのボルト孔をスロットホールとするとともに、この添板やジョイントアングルの外側に摩擦板を当接して、H形断面材と添板やジョイントアングルと摩擦板を高力ボルトで締結することにより、H形断面材と添板やジョイントアングルと摩擦板間で滑り摩擦を発生させるようにした履歴減衰型の摩擦ダンパーを備えたものであり、中小規模の地震から大地震に至るまでの広範囲な荷重に対して摩擦力によるエネルギー吸収機能を有するH形断面材または箱形断面柱とH形断面梁の高力ボルト摩擦接合構造である。
【0014】
本発明でいう、ジョイントアングルは、垂直板と水平板からなり断面が山形のものであり、基本形としては以下の4種がある。
(1)一方の部材に当接される側では垂直板にボルト孔を有し、他方の部材に当接される側では水平板にボルト孔を有するもの。
(2)一方の部材に当接される側も、他方の部材に当接される側も水平板にボルト孔を有するもの。
(3)一方の部材に当接される側も、他方の部材に当接される側も水平板と垂直板にボルト孔を有するもの。
(4)一方の部材に当接される側も、他方の部材に当接される側も水平板にボルト孔を有し、いずれか一方の側の垂直板にのみボルト孔を有するもの。
【0015】
本発明の高力ボルト摩擦接合構造においては、履歴減衰型の摩擦ダンパーを備えているので、荷重変形曲線がループを描くことを利用して振動を減衰させ、柱・梁などの主材に対する応力と変形を小さくさせることができ、結果として相対的な接合部構造の耐力を向上させることができる。
例えば、添板を用いた場合については、添板のボルト孔をスロットホール(ここでは、H形断面材の軸方向の径を長径にした長孔を意味する。以下「スロットホール」という。)にして、H形断面材に荷重が作用して添板と摩擦板間と添板とH形断面材間に発生した最大摩擦力に克って滑りを生じた場合に、高力ボルトの軸部がスロットホール内を一定の距離移動する過程で、特に摩擦板付加による滑り摩擦で、最大摩擦力に近い応力を安定して接合部で伝達させることができる。
【0016】
この種の高力ボルト摩擦接合においては、各ボルト孔に高力ボルトを円滑に挿入できるように、ボルト孔を真円とし、その孔径を高力ボルトの軸径より2〜3mm程度大きく設定しているが、本発明では、添板の外側に摩擦板を当接して高力ボルトで締結することを前提として、摩擦板のボルト孔、H形断面材のボルト孔はボルト挿入が可能なレベルで従来の孔径によりも極力小さくして、添板の摩擦板を当接する領域のボルト孔をスロットホールにするものである。このスロットホールは、添板やジョイントアングルのボルト孔に適用するが、全部のボルト孔をスロットホールにすることは必要条件ではなく、例えば一方のH形断面材側のみをスロットホールにしてもよい。構造性能の明確化、加工コスト、施工性などを考慮した場合には、一方のH形断面材側のボルト孔のみをスロットホールにすることが有利であることが多い。
【0017】
このスロットホールになるボルト孔の長径は、高力ボルトの径に対して1.5〜2.5倍程度に設定することが望ましい。長径が高力ボルト軸径の1.5未満では、滑り摩擦による減衰効果が十分ではない。また、滑り摩擦による減衰効果には限界があり、長径が高力ボルト軸径の2.5倍超にしても、接合部構造全体としての耐力向上につながらないことから、断面減少や加工のコストアップのことを考えれば、高力ボルト軸径の2.5倍超にすることは得策ではない。ただし、この条件は、各部材の強度、各摩擦面での摩擦力、荷重、減衰の目標値等を考慮して設定することができる。
【0018】
添板やジョイントアングルの外側に当接する摩擦板は、添板やジョイントアングルの各スロットホールに挿通した各高力ボルト単位で独立させて摩擦増設座金(通常の座金より摩擦面を大きくした摩擦板機能を兼備した座金、以下「摩擦増設座金」という。)として配置することが、材料コストを節減し滑り摩擦を効率的に確保する観点でより有効である。この摩擦板の形状は、正方形または円形が主体である。ボルト孔はボルトが挿入できる範囲内で極力小さい径に設定することが好ましい。
複数の高力ボルトに対して摩擦板を一枚で共用することは、ボルト挿入の面から、施工的に非常に難しく、コスト増となることから不利である。
本発明で使用する高力ボルトとしては、ナット螺合側の先端にトルクコントロール機構を備えたトルシア形高力ボルトや高力六角ボルトなどの周知の高力ボルトを用いることができる。なお、各接合面での滑り現象を制御するために、接合面に0.6以上のすべり係数が得られる高摩擦処理を施すことも有効である。
【0019】
【実施例】
[実施例1]
以下に、本発明の実施例1を図1〜図4に基づいて詳細に説明する。
この実施例1は、箱形断面柱1とH形断面梁4を用いた両方向ラーメン構造において、接合構造として図9に示したような通しダイアフラム形式の接合構造を採用し、箱形断面柱1に取り付けられたダイアフラム2に溶接されたH形断面を有する梁取付部3の上下フランジ3a、3bと、H形断面梁の上下フランジ4a、4bを、それぞれ外側の添板51と内側の添板52、53を介して高力ボルト接合し、梁取付部3のウエブ3uとH形断面梁4のウエブ4uを、左右一対の添板61と62を介して高力ボルト7で接合する箱形断面柱1とH形断面梁4の高力ボルト摩擦接合構造として適用したものである。

BACKGROUND OF THE INVENTION
For example, when a steel structure building is constructed, the present invention provides a high-strength bolt friction joint structure of an H-shaped cross-section column or box-shaped cross-section column and an H-shaped cross-section beam, or an H-shaped cross-section beam and an H-shaped cross-section beam. The present invention relates to a high-strength bolt friction joint structure applied in a high-strength bolt friction joint structure.
[0002]
[Prior art]
In recent years, a bi-directional frame structure using a box-shaped cross-section column and an H-shaped cross-section beam has been widely used. As the joint structure, a through-diaphragm-type joint structure as shown in FIGS. 9A to 9C is used. Yes. In this type of joint structure, the box-shaped cross-section column 1 and the upper and lower diaphragms 2a and 2b and the column core 2c are joined together, and the diaphragm 2 and the beam attachment part 3 are joined by welding w. The beam 4 is connected between the flanges 3a, 3b and 4a, 4b via outer and inner accessory plates 5a, 5b, 5c, and between the webs 3u and 4u, a pair of left and right accessory plates 6a and 6b. Respectively, and were joined by high-strength bolts 7.
[0003]
Recently, as shown in FIGS. 10A to 10C, the flange 8f of the pair of upper and lower split tees 8a and 8b is attached to the box-shaped cross-section column 1 without using a diaphragm or a beam mounting portion. The joint structure that reduces the welding burden by joining the upper and lower flanges 4a, 4b of the H-shaped cross-section beam 4 to the horizontal web 8u of the pair of upper and lower split tees 8a, 8b with a high-strength bolt 10 is adopted. It is becoming.
[0004]
In such a joint structure, for example, use of a friction damper having an energy absorbing function has been attempted in order to ensure a proof strength that can be applied over a wide range from a small-scale earthquake to a large earthquake. The friction damper is a hysteresis damping damper that shows the hysteresis characteristics of rigid plastic deformation. It attempts to damp vibrations by drawing the loop of the load deformation curve, and the area of the hysteresis loop is for one period. It corresponds to the energy absorbed in
As an example of such a friction damper, a friction plate material and a sliding plate material are clamped with high-strength bolts, and the damper function is exhibited by the friction force generated between both plates. In addition, a simple friction welding type energy absorption structure is known.
[0005]
For example, as shown in Japanese Patent Application Laid-Open No. 11-190147, this friction bonding energy absorbing structure is composed of two friction plates and one sliding plate member sandwiched between them, The plate member is a high-strength bolt-bonded member and cannot be displaced relatively, and has a normal bolt hole.
On the other hand, the sliding plate has a normal bolt hole on the other joining member side and is joined to a normal high strength bolt, and the high strength bolt is inserted into the one joining member side with respect to the high strength bolt. It has a slot hole (bolt hole) extending in the longitudinal direction so as to be displaceable.
[0006]
When a tensile force is applied to this friction-bonding type energy absorbing structure, if the frictional force generated between the friction plate and the sliding plate is exceeded, the sliding plate will move until the shaft of the high-strength bolt hits one wall of the slot hole. Can move. Further, when a compressive force is applied, the shaft portion of the high-strength bolt can move until it abuts against the other wall of the slot hole.
Therefore, when the tensile force or compressive force acts between the sliding plate and the friction plate exceeding the frictional force, the sliding plate can be expanded and contracted up to the length obtained by subtracting the shaft diameter of the high strength bolt from the length of the slot hole. Since it is possible, there is an advantage that energy from a small to large earthquake can be absorbed depending on the size selection of the slot hole.
[0007]
Such a friction bonding type energy absorbing structure is, for example, a high-strength bolt friction bonding structure of the box-shaped cross-section column and the H-shaped cross-section beam, or a high-strength bolt friction bonding structure of the H-shaped cross-section material and the H-shaped cross-section material. However, in order to ensure the required strength of the joint structure, the number of friction surfaces must be increased, which necessitates an increase in the number of friction plates and sliding plates, resulting in a complicated joint structure and an increase in construction burden. There is a problem that the material cost increases.
[0008]
[Problems to be solved by the invention]

The present invention provides a high-strength bolt friction joint structure of an H-shaped cross-section material or box-shaped cross-section column and an H-shaped cross-section beam provided with a friction damper having an absorbing function.

DETAILED DESCRIPTION OF THE INVENTION
In the present invention, for example, an H-shaped cross-section member or split tee attached to a box-shaped cross-section column is arranged so that the H-shaped cross-section beam is abutted, and the H-shaped cross-section material or split tee straddles the H-shaped cross-section beam. When high-strength bolt friction welding is performed on H-shaped cross-section beams via joint plates or joint angles that are in contact with each other, or H-shaped cross-section materials and H-shaped cross-sectional materials are This is mainly applied in the case of force bolt friction welding. The bolt hole of the accessory plate or joint angle is used as a slot hole, and the friction plate is brought into contact with the outside of the accessory plate or joint angle to form an H shape. The hysteresis is reduced by generating sliding friction between the H-shaped cross-section material, accessory plate, joint angle, and friction plate by fastening the cross-section material, accessory plate, joint angle, and friction plate with high-strength bolts. H-shaped cross-section material or box-shaped column and H-shaped cross-section beam with energy absorbing function by friction force for a wide range of loads from small to medium-scale earthquakes to large earthquakes This is a high strength bolt friction joint structure.
[0014]
The joint angle referred to in the present invention is composed of a vertical plate and a horizontal plate, and the cross section is a mountain shape, and there are the following four types of basic shapes.
(1) The vertical plate has a bolt hole on the side abutting on one member, and the horizontal plate has a bolt hole on the side abutted on the other member.
(2) Both the side abutted against one member and the side abutted against the other member have bolt holes in the horizontal plate.
(3) Both the side that is in contact with one member and the side that is in contact with the other member have bolt holes in the horizontal and vertical plates.
(4) Both the side abutting on one member and the side abutting on the other member have bolt holes in the horizontal plate, and only one of the vertical plates has the bolt hole.
[0015]
The high-strength bolt friction joint structure of the present invention is equipped with a hysteresis damping friction damper, so that the load deformation curve draws a loop to dampen vibration and stress on the main material such as columns and beams. As a result, the relative strength of the joint structure can be improved.
For example, in the case of using the accessory plate, the bolt hole of the accessory plate is a slot hole (in this case, it means a long hole in which the diameter in the axial direction of the H-shaped cross-sectional material is the longer diameter, hereinafter referred to as “slot hole”). When a load is applied to the H-shaped cross-section material and slippage occurs over the maximum friction force generated between the accessory plate and the friction plate and between the accessory plate and the H-shaped cross-section material, the shaft of the high-strength bolt In the process in which the portion moves in the slot hole by a certain distance, stress close to the maximum friction force can be stably transmitted at the joint portion, particularly by sliding friction due to addition of a friction plate.
[0016]
In this type of high-strength bolt friction welding, the bolt hole is made into a perfect circle so that the high-strength bolt can be smoothly inserted into each bolt hole, and the hole diameter is set to be about 2 to 3 mm larger than the shaft diameter of the high-strength bolt. However, in the present invention, the bolt hole of the friction plate and the bolt hole of the H-shaped cross-section material can be inserted into the bolt on the premise that the friction plate is brought into contact with the outside of the accessory plate and fastened with a high-strength bolt. The bolt hole in the region where the friction plate of the accessory plate abuts is made into a slot hole by making it as small as possible compared with the conventional hole diameter. This slot hole is applied to an accessory plate or a joint angle bolt hole. However, it is not a necessary condition that all the bolt holes are slot holes. For example, only one H-shaped cross-section side may be a slot hole. . In consideration of clarification of structural performance, processing cost, workability, etc., it is often advantageous to use only the bolt hole on one H-shaped cross-section side as a slot hole.
[0017]
The major axis of the bolt hole that becomes the slot hole is desirably set to about 1.5 to 2.5 times the diameter of the high-strength bolt. When the major axis is less than 1.5 of the high-strength bolt shaft diameter, the damping effect due to sliding friction is not sufficient. In addition, there is a limit to the damping effect due to sliding friction, and even if the major axis exceeds 2.5 times the diameter of the high-strength bolt shaft, it does not lead to an improvement in the yield strength of the entire joint structure. In view of the above, it is not a good idea to make it more than 2.5 times the diameter of the high-strength bolt shaft. However, this condition can be set in consideration of the strength of each member, the frictional force on each friction surface, the load, the target value of attenuation, and the like.
[0018]
The friction plate that contacts the outside of the accessory plate or joint angle is a friction plate with a friction surface larger than that of a normal washer, with each high-strength bolt inserted through each slot hole of the accessory plate or joint angle. It is more effective to arrange as a washer having a function (hereinafter referred to as a “friction expansion washer”) from the viewpoint of saving material costs and efficiently ensuring sliding friction. The shape of the friction plate is mainly square or circular. The bolt hole is preferably set to a diameter as small as possible within a range in which the bolt can be inserted.
Sharing a single friction plate for a plurality of high-strength bolts is disadvantageous because it is very difficult in terms of construction and increases the cost in terms of bolt insertion.
As the high-strength bolt used in the present invention, a well-known high-strength bolt such as a torcia-type high-strength bolt or a high-strength hexagon bolt having a torque control mechanism at the tip end of the nut screwing side can be used. In addition, in order to control the slip phenomenon at each joint surface, it is also effective to perform a high friction process that can obtain a slip coefficient of 0.6 or more on the joint surface.

When the force is overcome and slip occurs, the shaft of the high-strength bolt moves in the slot hole of each accessory plate for a certain distance, especially by sliding friction due to the addition of an additional friction washer. Near stress can be stably transmitted at the joint. As a result, it is possible to prevent damage to main materials such as a box-shaped cross-section column and an H-shaped cross-section beam during an earthquake, etc., and improve the safety of the entire structure.
