法、片持ち式1法、引出し式1法等が知られている。[Prior art and problems to be solved by the invention] Conventionally, construction methods for constructing bridges on heavily trafficked roads, railway lines, waterways, etc., where shoring cannot be installed between the supports, include the erection girder construction method, the cantilever type 1 method, Drawer type 1 method and the like are known.
しかしながら上記従来の工法は、工事のための仮設工事
費用が多額になったり、隣接してかなり広い工事用地を

徴としている。In order to achieve the above object, the present invention installs column rows consisting of mutually opposing columns on both sides of the site at sites where shoring cannot be installed in the middle, and uses girder beams in the girder direction between the columns on each side. a step of connecting, a step of mounting a horizontal member with an extended hand rolling machine on top of the column head along the − side column row, and a step of mounting the horizontal member with a raised hand rolling machine on top of the column head along the column on the negative side; As a result, the raising hand rolling machine side is turned in the direction of the supporting column on the other side facing the raising hand rolling machine, and the side of the horizontal member opposite to the raising hand rolling machine is rotated to take a reaction force with a wire. The process involves removing the second-half manual rolling machine that has been pulled out in the direction of the columns and supporting both ends of the horizontal beams, and sending the horizontal beams in the direction of the girder, and sequentially applying the horizontal beams to each of the opposing columns in the rows of columns on both sides. It is characterized by a method of constructing horizontal members using a combination of turning and raw potato rolling, which is constructed through a process of erection.
架設する横架材は、当初支柱列に沿った状態で支柱頭部
に上架し、その後架設方向に旋回するから、狭い工事用
地で横架材の組立て上架を行うことができ、かつ上架旋
回後横架材は空中にあるため支柱高さ以下の地上物件に
何ら制約を与えない。The horizontal members to be erected are initially placed on top of the column heads along the column rows, and then rotated in the direction of erection, making it possible to assemble and erect the horizontal members in a narrow construction site, and to make the installation easier after the upper structure is rotated. Since the horizontal members are in the air, they do not impose any restrictions on objects on the ground that are below the height of the pillars.

、横架材の引出しによってその重心点が横架材の支点か
ら移動し、横架材に転倒モーメントが生じるが、この転
倒モーメントは惜みワイヤの反力によって平衡される。If the horizontal member is pulled out in the direction of the opposite pillar on the other side, and the tip of the hand-raising machine is supported by the pillar on the other side, the horizontal member will be stabilized by the pillars on both sides in the same state as when it is supported at both ends. Supported. Until the tip of the raising hand rolling machine reaches the support on the other side, the center of gravity moves from the fulcrum of the horizontal member as the horizontal member is pulled out, and an overturning moment is generated in the horizontal member. is balanced by the reaction force of the wire.
横架材は挙手延機によって長さが延長されているため惜
みワイヤによって反力をとる必要がある距離は僅かです
む。Since the length of the horizontal member is extended by the raising hand stretching machine, the distance over which it is necessary to take up the reaction force with the cutting wire is small.
挙手延機の先端が対向他側の支柱に達した後、さらに横
架材の引出しを続け、横架材の両端が両側の支柱に支持

架材を架設していく。After the tip of the hand-raising machine reaches the column on the other side, continue to pull out the horizontal member, and when both ends of the horizontal member are supported by the pillars on both sides, remove the hand-raising machine and remove the horizontal member. The horizontal members are sent in the girder direction, and the above steps are repeated to sequentially erect the horizontal members on the opposing columns of the column rows on both sides.

で行うため、横架材の組立て上架、旋回、惜みワイヤの
設置、横架材の引出し等の作業は一個所ですみ、用地の
節約と工事の合理化を果すことができる。In the above construction method, the horizontal members are moved at fixed support points, so work such as assembling the horizontal members, raising them, turning them, installing loose wires, and pulling out the horizontal members can be done at one place. It can save money and streamline construction work.

1 is lowered, the horizontal member 3 of the extension of the raising hand rolling machine 4 is a temporary pedestal 6.
It is supported in a horizontally balanced state with ′ as the fulcrum. Therefore, use a dragnet or the like to turn the horizontal member 3, which is an extension of the raised hand rolling machine 4, by 90', and direct the raised hand rolling machine 4 in the direction of the supporting column 1'' on the other side.
Wire wire 13 tied to the opposite side of the horizontal member 3 from the hand stretching machine
The earth anchor 14 has been driven into a predetermined position in advance.
At the same time, the wire 15 of the winch 10 for drawing out the horizontal member 3 is tied to the tip of the raising hand rolling machine 4 (Figs. 4 and 5).

At this time, the upper surface of the temporary pedestal 6# of the supporting column l'' on the opposite side and the jack 9 of the temporary supporting column 8 on which the tip of the raised hand stretching machine 4 rests is raised to the same level as the temporary pedestal 6' on the supporting column 1' side. When the drawer is drawn out, the center of gravity G of the horizontal member 3 extending from the hand-raising machine 4 moves toward the drawer side, and an overturning moment is generated in the horizontal member 3 extending from the hand-raising machine 4 . The tension wire 13 is balanced by the force.An auto-reel 13a is interposed in the middle of the tension wire 13 to accommodate changes in the length of the tension wire 13 as the horizontal member 3 is pulled out.

られるものである。As described above, in a site where no shoring can be installed in the middle, the present invention installs column rows consisting of mutually opposing columns on both sides of the site, and connects the columns on each side with girder beams in the girder direction. a step of placing a horizontal member with a raised hand rolling machine on top of the column head along the - side column row; The step of rotating the raw sweet potato rolling machine side toward the supporting column on the other side opposite to it, and taking a reaction force with a sparing wire on the side of the horizontal member opposite to the raised hand rolling machine; The process involves removing the second-half manual rolling machine that has been pulled out in the direction of the columns and supporting both ends of the horizontal beams, and sending the horizontal beams in the direction of the girder, and sequentially applying the horizontal beams to each of the opposing columns in the rows of columns on both sides. It is erected through a process of erection, and the horizontal members to be erected are in a state along the column of columns when assembled, and when swiveled or pulled out, they are in the air and attached to the ground object below the height of the column. It is extremely useful for construction in urban areas where it is difficult to secure construction land without conflict. In addition, the construction work is streamlined because the bridges are moved at fixed support locations. Furthermore, since the cross-member frames are moved by extending the length of the cross-members using a hand-stretching machine and by supporting the reaction force using loose wires, it is difficult to install intermediate supports on roads or railways with heavy traffic. This provides many benefits, such as making it possible to erect large-span horizontal members even on sites such as railroads and waterways.
