法が広く採用されている。
Cable-stayed bridges have been developed in which diagonal members are extended to the left and right from an erected tower, and the bridge girder is lifted up by these diagonal members. In order to extend the stay members in this cable-stayed bridge, a method is widely adopted in which the ends of the stay members are passed through the tower and fixed on the opposite side.
このような方法であると第６図に示すように、
塔ａ内にて左右に張出した斜材ｂ，ｂがぶつかり
合わぬように上下にズラして通す必要が生じ、斜
張橋全体の外観としては、塔ａから斜材ｂが左右
に対称に張り出ないことになる。つまり斜張橋は
塔ａの左右がアンバランスな印象を与え外観が良
くないものとなつていた。 With this method, as shown in Figure 6,
It becomes necessary to shift the stay members b and b that extend left and right inside tower a vertically so that they do not collide with each other, and the overall appearance of the cable-stayed bridge is that the stay members b are symmetrical from tower a to left and right. It will not stick out. In other words, the cable-stayed bridge gave the impression that the left and right sides of tower a were unbalanced, and the appearance was not good.
この発明は外観体裁の良好な斜張橋の斜材配設

The method for installing cable members in a cable-stayed bridge according to the present invention is to divide a plurality of PC members of the cable members extending from one side of the tower into two parts within the tower, penetrate the tower to the opposite side, and fix the cable members.
A plurality of PC materials of the diagonal members extending to the other side of the tower are passed between the two divided PC materials and penetrated to the opposite side to be fixed.

る。 The ends of the diagonal members 2 pass through the inside of the tower 1 and are fixed on the opposite side, but the plurality of PC materials 4 of the diagonal members 2 on one side of the diagonal members 2 extending left and right are divided into two. It is fixed on the opposite side. Inside the tower 1, as shown in FIG. 4, an insertion pipe 5 divided into two forks is provided, and a socket 6 is attached to each end of the insertion pipe 5. The PC material 4, which is divided into two parts, is fixed to the anchor head 8 by a wedge 7 through this insertion pipe 5. Insertion pipe 5
Two steel plates 10, 10 are slidably connected to the inner wall of the PC member 4 with an anti-friction material 9 such as Teflon material in between, and the steel plate 10 ensures the sliding of the PC material 4.
(FIG. 5) The insertion pipe 5 and the socket 6 are filled with oil or a filler having a rust-preventing effect.

されている。 The diagonal member 2 penetrating the tower 1 from the other side passes between the PC members 4 of the diagonal member 2 divided into two parts and penetrates to the opposite side. That is, a cylindrical insertion pipe 1
1 are disposed so as to pass through between the forked insertion pipes 5 and intersect diagonally. The PC material 4 of the diagonal member 2 passed through the insertion pipe 11 passes through to the opposite side and is fixed to the anchor head 8 by a wedge 7.

This invention has the above-mentioned configuration, and the diagonal material extending to one side of the tower is divided into two pieces of PC material in the tower, penetrated to the opposite side of the tower and fixed, and then attached to the other side of the tower. Since the multiple PC materials of the overhanging diagonal members were passed between the two divided PC materials and penetrated to the opposite side and fixed, the PC materials could be crossed at the same height without colliding in the tower, and the tower Diagonals can be extended from both sides at the same height. Therefore, the overall appearance of the cable-stayed bridge is such that the cable members protrude symmetrically to the left and right sides of the tower, resulting in a good external appearance.
