Description
本発明は、橋梁及びその施工時に用いる上部工に関するものであり、特に橋梁の強度を高めるものに関するものである。 The present invention relates to a bridge and a superstructure used at the time of construction thereof , and particularly relates to a bridge that increases the strength of the bridge.
従来の上部工を用いる橋梁の施工方法である杭式桟橋の施工方法について図18を用いて説明する。杭頭固定用管4が予め設置された桟橋未完成部分の主桁1を桟橋完成部分から片持ち状に張り出し、当該桟橋未完成部分の主桁1に沿って当該主桁1の張り出し先端部と桟橋完成部分との間にかけ渡された線材2を、当該主桁1と平行になるように張力調整することによって当該主桁1の方向や角度、あるいは歪み状態を完成状態に近づくように調整保持する。これにより、当該主桁1に取り付けられている杭頭固定用管4の位置を完成状態に近づけて、その杭頭固定用管4を介して管状杭5を杭打ちする。また、杭頭固定用管4が取り付けられている横桁3と主桁1とを周方向に回転可能な二重管構造で接続する。これにより、主桁1と杭頭固定用管との角度変化に対応して部品の種類を低減し、コストダウンを図ることができる。 The construction method of the pile type pier which is the construction method of the bridge using the conventional superstructure is demonstrated using FIG. The main girder 1 of the unfinished pier where the pile head fixing pipe 4 has been installed in advance is cantilevered from the completed part of the pier, and the projecting tip of the main girder 1 extends along the main girder 1 of the unfinished pier By adjusting the tension of the wire 2 passed between the bridge and the completed part of the jetty so that it is parallel to the main girder 1, the direction, angle, or distortion state of the main girder 1 is adjusted to approach the completed state. Hold. Thereby, the position of the pipe head fixing pipe 4 attached to the main girder 1 is brought close to the completed state, and the tubular pile 5 is driven through the pile head fixing pipe 4. Moreover, the cross beam 3 to which the pile head fixing pipe 4 is attached and the main beam 1 are connected by a double pipe structure that can rotate in the circumferential direction. Thereby, the kind of components can be reduced corresponding to the angle change with the main girder 1 and the pile head fixing pipe, and cost reduction can be aimed at.
しかしながら、前述の従来の杭式桟橋の施工方法には、以下に示すような改善すべき点がある。従来の杭式桟橋の施工方法では、図18(b)に示すように、杭頭固定用管4の上面P4と覆工板6との間に間隔が生じている。このため、杭頭固定用管4上に配置される天蓋(図示せず)によってのみ、管状杭5からの突き上げと上部工自身の荷重とを保持しなければならない。このため、杭式桟橋の強度をさらに高めることが難しいという改善すべき点がある。 However, the above-described conventional method for constructing a pile jetty has the following points to be improved. In the conventional method for constructing a pile-type pier, as shown in FIG. 18 (b), an interval is generated between the upper surface P 4 of the pile head fixing pipe 4 and the lining plate 6. For this reason, only the canopy (not shown) arrange | positioned on the pipe 4 for pipe head fixing must hold | maintain the thrust from the tubular pile 5, and the load of superstructure itself. For this reason, there is a point to be improved that it is difficult to further increase the strength of the pile-type jetty.

The upper work 201 is placed at a predetermined position by the crane truck CT, and the main beam 111b of the upper work 201 and the main beam 111a of the upper work SS are connected. As a result, the upper work 201 is cantilevered with respect to the upper work SS. When the upper work 201 is cantilevered at a predetermined position, a wire rod (for example, a piano wire) is passed between the main beam 111b of the upper work 201 to be connected and the main beam 111a of the upper work SS. By adjusting the tension of the wire rod so as to be parallel to the main girder 111a of the work SS, the state of the main girder 111b of the upper work 201, the angle, the distortion, and the like may be brought closer to the state at the time of completion ( JP 2000-96582).

After placing the mortar on the pile head, the pile head canopy TC is fixed to the upper surface of the pile head fixing member 115. The pile head fixing member 115 and the pile head canopy TC are fixed to a hole 115g formed in the flange portion 115f (see FIG. 2) of the pile head fixing member 115 and a hole formed in the pile head canopy TC. Insert the bolt and fix it with a nut.
そして、図14(b)に示すように、設置した上部工201の上にクローラ用足場を敷設する。その後、図14(c)に示すように、鋼管杭SP(3)の施工と同様にして、鋼管杭SP(4)を施工し、クローラ用足場を敷設する。これにより、クレーン車CTによる床版の敷設のための領域を確保する。そして、既に敷設したクローラ用足場を除去した後、除去した領域に床版を敷設する。これにより、橋梁施工における標準部の施工を完了する。 Then, as shown in FIG. 14B, a crawler scaffold is laid on the installed superstructure 201. Then, as shown in FIG.14 (c), steel pipe pile SP (4) is constructed similarly to construction of steel pipe pile SP (3), and the crawler scaffold is laid. Thereby, the area | region for laying the floor slab by the crane vehicle CT is ensured. Then, after removing the already laid crawler scaffold, a floor slab is laid in the removed area. Thereby, the construction of the standard part in the bridge construction is completed.

First Superstructure Configuration The superstructure 301 used in the bridge construction method according to the present invention will be described with reference to FIG. The superstructure 301 is used when constructing a bridge having an inclination. 15A is a top view of the upper work 301, FIG. 15B is a front view of the upper work 301, and FIG. 15C is a right side view of the upper work 301. In FIGS. 15A to 15C, the same components as those in FIGS. 1A to 1C are denoted by the same reference numerals, and detailed description thereof is omitted.
上部工301は、主桁311、横桁113及び杭頭固定部材115を有している。主桁311及び横桁113は、梯子状に配置されている。また、主桁311及び横桁113は、H型鋼により形成されている。 The superstructure 301 includes a main beam 311, a horizontal beam 113, and a pile head fixing member 115. The main beam 311 and the horizontal beam 113 are arranged in a ladder shape. The main beam 311 and the horizontal beam 113 are made of H-shaped steel.
主桁311は、相対的に短い主桁311a、311c及び相対的に長い主桁311bにより構成されている。図15(c)に示すように、主桁311a及び主桁311cは、それぞれ一端が杭頭固定部材115の側面部115a(図2参照)に溶接され、固定されている。また、図1(a)、(c)に示すように、主桁311bの両端は、主桁311の杭頭固定部材115に固定されていない一端と、所定の固定板、及びボルト、ナットを用いて互いに突き合わされ、直線上に接合されている。 The main girder 311 is composed of relatively short main girders 311a and 311c and a relatively long main girder 311b. As shown in FIG. 15C, one end of each of the main girder 311a and the main girder 311c is welded and fixed to the side surface portion 115a (see FIG. 2) of the pile head fixing member 115.

Using each other and joined on a straight line.
図15(a)に示すように、杭頭固定部材115は、中心C5が主桁311の中心軸J1上に配置されている。また、杭頭固定部材115は、中心C5が横桁113の中心軸J3の中心軸J3上に配置されている、つまり、杭頭固定部材115は、中心C5が主桁311の中心軸J1と横桁113の中心軸J3との交点上に存在するように配置されている。また、図15(b)に示すように、杭頭固定部材115は、上面P5が杭頭固定部材115を貫通する鋼管杭の中心軸J5に対して垂直となるように配置される。さらに、図15(c)に示すように、杭頭固定部材115を挟んで配置される主桁311a、311cは、直線上に配置される。一方、主桁311a及び主桁311cの間に接続される主桁311bは、斜めに配置される。つまり、図15(c)に示すように、上部工301は、杭頭固定部材115周辺の平坦な部分と主桁311bに沿う斜めの部分とが交互に配置される傾斜面を有している。 As shown in FIG. 15A, the pile head fixing member 115 has the center C <b> 5 disposed on the central axis J <b> 1 of the main girder 311. In addition, the pile head fixing member 115 is arranged on the center axis J3 of the center axis J3 of the cross beam 113, that is, the pile head fixing member 115 has the center C5 and the center axis J1 of the main girder 311. It arrange | positions so that it may exist on the intersection with the central axis J3 of the cross beam 113. FIG. 15B, the pile head fixing member 115 is disposed so that the upper surface P5 is perpendicular to the central axis J5 of the steel pipe pile passing through the pile head fixing member 115. Furthermore, as shown in FIG.15 (c), the main girders 311a and 311c arrange | positioned on both sides of the pile head fixing member 115 are arrange | positioned on a straight line. On the other hand, the main beam 311b connected between the main beam 311a and the main beam 311c is arranged obliquely. That is, as shown in FIG. 15C, the superstructure 301 has an inclined surface in which flat portions around the pile head fixing member 115 and oblique portions along the main beam 311b are alternately arranged. .
第2 上部工301を用いた施工
上部工301を用いた乗り込み部施工時における橋梁の施工については、実施例1と同様である。また、標準部施工時における施工においては、実施例2と同様に、コの字状(図10参照)で、主桁311の主桁311bが斜めに配置される上部工を用いて施工する。標準部施工時における橋梁の施工については、実施例2と同様である。
Construction using the second superstructure 301 The construction of the bridge at the time of entry work construction using the superstructure 301 is the same as in the first embodiment. Moreover, in the construction at the time of construction of the standard part, similarly to the second embodiment, construction is performed using an upper work in which the main girder 311b of the main girder 311 is obliquely arranged in a U-shape (see FIG. 10). The construction of the bridge at the time of construction of the standard part is the same as in Example 2.
ここで、床版FS及び調整用コンクリートASが施工された状態の上部工301の側面図を図16に示す。なお、図16においては、一部の杭頭固定部材115及び一部の鋼管杭SPを断面にて表示している。 Here, FIG. 16 shows a side view of the superstructure 301 in a state in which the floor slab FS and the adjustment concrete AS are applied. In addition, in FIG. 16, some pile head fixing members 115 and some steel pipe piles SP are displayed by the cross section.
実施例1における上部工101を用いた施工と同様に、上部工301を用いた施工においても、鋼管杭SPが杭頭固定部材115の上面P5に対して垂直に杭頭固定部材115に挿通され、天蓋TCによって杭頭固定部材115の上面P5が閉じられた後、天蓋TC上に床版FSが施工される。したがって、杭頭固定部材115の上面P5は、天蓋TCを介して、間接的に床版FSの下面PFに接している。これにより、床版FSからの過重F1を、鋼管杭SPによる突き上げの力F2に対抗させることができる。よって、高い強度を有する橋梁の施工が可能となる。なお、上部工301を用いて所定の傾斜面を形成するために、調整用コンクリートAC2を施工する。 Similarly to the construction using the superstructure 101 in the first embodiment, also in the construction using the superstructure 301, the steel pipe pile SP is inserted into the pile head fixing member 115 perpendicularly to the upper surface P5 of the pile head fixing member 115. After the top surface P5 of the pile head fixing member 115 is closed by the canopy TC, the floor slab FS is constructed on the canopy TC. Therefore, the upper surface P5 of the pile head fixing member 115 is in contact with the lower surface PF of the floor slab FS indirectly through the canopy TC. Thereby, the excess weight F1 from the floor slab FS can be made to oppose the pushing force F2 by the steel pipe pile SP. Therefore, it is possible to construct a bridge having high strength. In addition, in order to form a predetermined inclined surface using the superstructure 301, the adjustment concrete AC2 is applied.

For example, as in the superstructure 102 shown in FIGS. 17A and 17B, three main beams 112a, main beams 112b, and main beams 112c are combined to form the main beam 112. Furthermore, you may make it form the main beam arrange | positioned between the pile head fixing members 115 by one main beam, without couple | bonding a several main beam. In this case, pile head fixing members 115 are coupled to both ends of the main beam.
