Description

鋼コンクリートの重ね梁は架け橋工事の中に多用される組み合わせ構造形式であり、それはせん断力コネクタにより鉄骨梁とコンクリート板を一体に接続し共同的に働かせる抗折部材である。鋼コンクリートの重ね梁はせん断力コネクタにより鋼とコンクリートを一体にさせて共同的に働かせ、せん断力コネクタが鋼とコンクリートとの界面に位置し、鋼コンクリートの重ね梁の肝心な部品として、鉄骨梁とコンクリートスラブとの間の縦向きせん断力を受けまた伝送し、鋼とコンクリートのスリップを防止する；その同時、せん断力コネクタがコンクリートスラブと鉄骨梁との間の持ち上げ作用を抵抗する。目下多用されるせん断力コネクタがそのせん断強度により下記のように区分されることができる：柔軟性コネクタと、弾性コネクタと剛性コネクタである；構造の形式により下記のように区分されることができる：スタッドコネクタと、形鋼コネクタと、鉄筋コネクタなどである。この同時、近年以来、我が国が工事構造の振動抑制と振動コントロールの面で大量な研究活動を行い、豊かな実りをいっぱい取り、エネルギ消費と振動抑制が受動コントロール措置であり、構造に輸入される振動エネルギーを特別に設置される機構と部品のほうに引きつけて吸収とエネルギ消費を行い、そこから主体構造の安全を保護することができる。但し現有な鋼コンクリートの重ね梁の整合性が悪く、ダンピング効果が不如意である。 The steel-concrete combination structure employs a combination of steel and concrete or steel and reinforced concrete and connects it to the overall member by reliable connecting measures. The combination structure of steel and concrete has been widely applied in structural construction since recent years because it can fully demonstrate the characteristics of reinforcing bars and concrete. The advantages of the steel-concrete combination structure are: high bearing capacity, high rigidity, good ductility, saving steel materials, reducing construction cost, convenient for construction, etc., with good technical and economic effects. it can.
Steel-concrete lap beams are a combination structure type that is often used in bridge construction, and are anti-folding members that integrally connect steel beams and concrete plates with shear force connectors and work jointly. Steel-concrete lap beams work together by integrating steel and concrete with shear force connectors, and the shear force connector is located at the interface between steel and concrete, and steel beams are an essential part of steel-concrete lap beams. It receives and transmits the longitudinal shear force between the and the concrete slab to prevent the steel and concrete from slipping; at the same time, the shear force connector resists the lifting action between the concrete slab and the steel beam. Currently frequently used shear force connectors can be classified according to their shear strength as follows: flexible connectors, elastic connectors and rigid connectors; depending on the type of structure, they can be classified as follows. : Stud connector, shaped steel connector, reinforced connector, etc. At the same time, since recent years, Japan has conducted a large amount of research activities in terms of vibration suppression and vibration control of construction structures, and has gained a lot of fruit. Energy consumption and vibration suppression are passive control measures and are imported into the structure. Vibration energy can be attracted to specially installed mechanisms and components to absorb and consume energy, from which the safety of the main structure can be protected. However, the consistency of the existing steel-concrete lap beams is poor, and the damping effect is unexpected.

図１と図２の示しているように、重ね梁の性能を上げる構造はビームと工字型の鉄骨梁を含む。ビームの長度方向が横向き方向で、鉄骨梁の上部が横向き方向に沿ってビームの内部に嵌入し、ビームが鉄筋コンクリート製である。ビームの下端面と鉄骨梁にはいずれも複数のダンパが設置される；ダンパが二つのボータルフレームとダンピング部品を含み、ダンピング部品の一端が一つのボータルフレームに接続され、ダンピング部品の他端がもう一つのボータルフレームに接続される。 As shown in FIGS. 1 and 2, the structure that enhances the performance of the lap beam includes a beam and a work-shaped steel beam.

The end is connected to another fireal frame.

図１と、図２と、図３と図４の示しているように、工字型の鉄骨梁が一体で形成した上鋼板と、接続鋼板と下鋼板を含む；接続鋼板の上端が上鋼板の中心部と接続され、接続鋼板の下端が下鋼板の中心部と接続され、接続鋼板の上部と上鋼板がビームの内部に嵌入し、即ち上鋼板がビームの内部に位置し、縦向きに設置される接続鋼板の上部もビームの内部に位置する。ビームと鉄骨梁を作るには、ビームが打設方式で作られ、打設している時には、鉄骨梁の上部がちょうどまだできていないビームの内部に置き、このように打設が完了した後、鉄骨梁の上部がビームの内部に位置する。鉄骨梁の上部がビームの内部に位置する方式でボームと鉄骨梁の整合性を上げることができる。伝統的ではビームと鉄骨梁との間がせん断力コネクタにより接続され、伝統的なビームと鉄骨梁とが相互固定する関係であり、但し伝統的なビームと鉄骨梁との間にはせん断力コネクタがあることで、伝統的なビームと鉄骨梁の整合性が悪くなる。 As shown in FIGS. 1, 2, 3, and 4, the upper steel plate formed by integrally forming the work-shaped steel beam, the connecting steel plate, and the lower steel plate are included; the upper end of the connecting steel plate is the upper steel plate. The lower end of the connecting steel plate is connected to the center of the lower steel plate, and the upper part of the connecting steel plate and the upper steel plate are fitted inside the beam, that is, the upper steel plate is located inside the beam and is oriented vertically. The upper part of the connecting steel plate to be installed is also located inside the beam. To make the beam and the steel beam, the beam is made by the casting method, and when casting, the upper part of the steel beam is placed inside the beam that has not been made yet, and after the casting is completed in this way. , The upper part of the steel beam is located inside the beam. The consistency between the Baume and the steel beam can be improved by locating the upper part of the steel beam inside the beam. Traditionally, the beam and the steel beam are connected by a shear force connector, and the traditional beam and the steel beam are mutually fixed, except that the traditional beam and the steel beam are connected by a shear force connector. The presence makes the traditional beam inconsistent with the steel beam.

上鋼板の上表面には複数の縦向きスタッドが設置され、複数の縦向きスタッドが矩形のように配列分布され、即ち複数の縦向きスタッドが横向き方向と縦向き方向に沿って均一分布され、接続鋼板の上部には複数の水平スタッドが設置され、複数の水平スタッドが横向き方向に沿って均一分布されている。縦向きスタッドと水平スタッドのいすれもビームの中に位置し、縦向きスタッドと水平スタッドがビームと鉄骨梁の整合性を強める。 A plurality of vertical studs are installed on the upper surface of the upper steel plate, and the plurality of vertical studs are arranged and distributed like a rectangle, that is, the plurality of vertical studs are uniformly distributed along the horizontal direction and the vertical direction. A plurality of horizontal studs are installed on the upper part of the connecting steel plate, and the plurality of horizontal studs are uniformly distributed along the lateral direction. Both the vertical and horizontal studs are located in the beam, and the vertical and horizontal studs enhance the alignment of the beam and the steel beam.

図５と、図６と、図７と、図８と図９の示しているように、ダンピング部品が第一弧形板と、第二弧形板と、ダンパマスと、固定板と固定ボルトを含む。第一弧形板の両端には第一接続板が設置され、第二弧形板の両端には第二接続板が設置され、第一弧形板と第二弧形板とが上下相対で設置され、下鋼板に装着されるダンパに対しては、第一弧形板が上方に位置し、第二弧形板が下方に位置し、固定板と第一接続板とがへばり付き、第一接続板と第二接続板とがへばり付き、第二接続板とボータルフレームの鉛直ブロックとがへばり付き、それから固定ボルトが順に接される固定板と、第一接続板と、第二接続板と、ボータルフレームを通り抜ける。第一弧形板から第二弧形板までの距離が中間から両端まで段々短くなり、即ち上方に位置する弧形板が上へ曲がり、下方に位置する弧形板が下へ曲がり、ダンパマスの上弧形表面が上へ凸起し、ダンパマスの下弧形表面が下へ凸起し、ダンパマスが第一弧形板と第二弧形板との間に位置し、即ちダンパマスが第一弧形板と第二弧形板から形成された空間の中に置かれ、且つダンパマスと第一弧形板及び第二弧形板とは固定されている。固定板の高度が第一接続板と第二接続板よりも高く、高度方向は上下方向であり、こうして二つのボータルフレームが相対変位する時に、固定板の作用により、変形を第一弧形板と第二弧形板に伝送することができ、仮に固定板の高度がより小さければ、変形が第一接続板と第二接続板に発生する可能性があり、第一接続板と第二接続板が断絶するほどまで至る。 As shown in FIGS. 5, 6, 7, 8, and 9, the damping parts are the first arc plate, the second arc plate, the damper mass, the fixing plate, and the fixing bolt. Including.

For the damper installed and mounted on the lower steel plate, the first arc-shaped plate is located above, the second arc-shaped plate is located below, and the fixing plate and the first connecting plate stick to each other. The first connection plate and the second connection plate stick to each other, the second connection plate and the vertical block of the firefly frame stick to each other, and then the fixing bolts are contacted in order. Go through the second connection plate and the firefly frame. The distance from the first arc plate to the second arc plate gradually shortens from the middle to both ends, that is, the arc plate located above bends upward, the arc plate located below bends downward, and the damper mass The upper arc-shaped surface protrudes upward, the lower arc-shaped surface of the damper mass protrudes downward, and the damper mass is located between the first arc-shaped plate and the second arc-shaped plate, that is, the damper mass is the first arc. It is placed in a space formed by a shape plate and a second arc shape plate, and the damper mass and the first arc shape plate and the second arc shape plate are fixed to each other. The altitude of the fixing plate is higher than that of the first connecting plate and the second connecting plate, and the altitude direction is the vertical direction. Thus, when the two firefly frames are displaced relative to each other, the deformation is caused by the action of the fixing plate. It can be transmitted to the plate and the second arcuate plate, and if the height of the fixing plate is lower, deformation can occur in the first connection plate and the second connection plate, and the first connection plate and the second It reaches the point where the connection plate is cut off.

図１０の示しているように、ボータルフレームが一体で形成した鉛直ブロックと水平ブロックを含む；水平ブロックがボルトにより鉄骨梁あるいはビームに固定され、固定ボルトが固定板と、第一接続板と第二接続板を鉛直ブロックに固定する。 As shown in FIG. 10, it includes a vertical block and a horizontal block integrally formed by the fireal frame; the horizontal block is fixed to the steel beam or beam by bolts, and the fixing bolts are the fixing plate and the first connecting plate. Fix the second connection plate to the vertical block.

複数のダンパが下鋼板に均一で分布装着され、複数のダンパがビームの下端面に均一で分布装着され、即ち下鋼板にある複数のダンパが均一分布され、ビームの下端面にある複数のダンパも均一分布されている。 A plurality of dampers are uniformly distributed and mounted on the lower steel plate, and a plurality of dampers are uniformly distributed and mounted on the lower end surface of the beam, that is, a plurality of dampers on the lower steel plate are uniformly distributed and a plurality of dampers on the lower end surface of the beam. Is evenly distributed.

第一弧形板と第一接続板が一体となって成型し、第二弧形板と第二接続板が一体となって成型し、第一弧形板と、第一接続板と、第二弧形板と、第二接続板がいずれも金属板である。 The first arc-shaped plate and the first connecting plate are integrally molded, the second arc-shaped plate and the second connecting plate are integrally molded, and the first arc-shaped plate, the first connecting plate, and the first Both the two-arc plate and the second connection plate are metal plates.

本発明の原理は：鉄骨梁の上部をビームの内部に嵌入することによって鉄骨梁とビームの整合性を上げる。その同時にビームと鉄骨梁には複数のダンパを装着されることを通じて本発明にダンピングのエネルギー消費の効果を備えさせ、ビームと鉄骨梁に曲げ変形が発生する時、ダンパの二つのボータルフレームが相対変位し、二つのボータルフレールが相互近づく場合、ダンパが圧されて、上方の弧形板が上へ曲げ、下方の弧形板が下へ曲げ、それによりダンピングのエネルギー消費の効果ができる；二つのボータルフレームが相互離れる場合、ダンパマスが牽引力を受け、上方の弧形板が下へ歪み、下方の弧形板が上へ歪み、それによりダンピングのエネルギー消費の効果ができる；二つのボータルフレームは上下に相対変位する時にまたは二つのボータルフレームが相対回転する時に、ダンパマスに曲げ変形が発生し、ダンピングのエネルギー消費の効果ができる。 The principle of the present invention is to improve the consistency between the steel beam and the beam by fitting the upper part of the steel beam inside the beam. At the same time, the beam and the steel beam are equipped with a plurality of dampers to provide the present invention with the effect of damping energy consumption. When the two firefly flares approach each other due to relative displacement, the damper is compressed and the upper arc plate bends upwards and the lower arc plate bends downwards, which can have the effect of damping energy consumption. When the two fireal frames are separated from each other, the damper mass receives traction force, the upper arc plate is distorted downward, the lower arc plate is distorted upward, which has the effect of energy consumption of damping; When the firefly frame is relatively displaced up and down or when the two firefly frames rotate relative to each other, bending deformation occurs in the damper mass, and the energy consumption effect of damping can be obtained.
