Abstract

PURPOSE:To shorten a construction period by constructing a main girder column capital section, and at the same time constructing the main tower as a fixed section of a diagonal material in a projecting construction method of the PC cable-stayed bridge. CONSTITUTION:Blocks C1-C5 of a corbel section and blocks T1 and T2 of the main tower are constructed. Then prefabricated scaffoldings 2 are re-shored, a plurality of main tower blocks are constructed on the block T2, at the same time, a lower stage horizontal beam is constructed, and a main girder column capital section is constructed. Then, a plurality of main tower blocks are also constructed on the main tower blocks, and the highest block is used for a fixed section on the main tower side. Wagons W1 and W2 are built up, fixed sections K1 and K2 of first diagonal cables B1 and B2 of a main girder are constructed, and the cables B1 and B2 are tensioned. While repeating the construction of both main tower and main girder at the same time, the diagonal cables are tensioned to construct a diagonal tensiole bridge. Since the main girder column capital section and main tower as the fixed section of the diagonal are not separately constructed as in a conventional construction, a construction period can be shortened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for a main tower and a main girder of a PC cable-stayed bridge.

[0002]

2. Description of the Related Art Conventionally, (1) as shown in FIG. 5, a block of corbel parts C1 to C4 is first constructed.

(2) Next, as shown in FIG. 6, a corbel portion C5 and main girder column heads H1 and H2 are installed. The main girder column heads H1 and H2 serve as a space for assembling a wagon (work erection vehicle).

(3) Next, as shown in FIG. 7, a frame scaffold 2 is erected on the main girder heads H1 and H2, and main towers T1 and T
Build block 2.

(4) Next, as shown in FIG. 8, the frame scaffold 2
And the blocks of the main towers T3 to T6 and the lower horizontal beams are constructed.

(5) Next, as shown in FIG.
Build a block of T9. In the case of this example, the main tower T9 serves as a fixing block for the first diagonal cables B1 and B2. Generally, the fixing position of the first diagonal cables B1 and B2 is usually located considerably above the main tower. Further, the wagens W1 and W2 are assembled and the blocks of the main girders K1 and K2 are constructed. Here, the main girders K1 and K2 are fixing blocks on the girder side of the first-stage diagonal cables B1 and B2.

(6) As shown in FIG. 10 below, the construction of the main tower and the construction of the main girder block by the movement of the wages W1 and W2 are carried out in parallel and the tensions of the diagonal cables B3 and B4 are repeated to construct the cable-stayed bridge. Was building.

[0008]

As described above, in the erection erection method for the PC cable-stayed bridge, the main girder is erected while the diagonal cable is erected, so the construction is not completed up to the anchoring block of the main tower. And I could not start the main girder construction.

It is an object of the present invention to provide a method of constructing a slant cable of a main tower block in advance by fixing it to a fixing portion to shorten the construction period.

[0010]

[Means for Solving the Problem] In a PC cable-stayed bridge, a part of the block of the corbel part and a block of the lower main tower part are constructed, and the frame scaffolding is re-established so that the upper main tower block and the lower horizontal beam are installed. At the same time as the construction, construct the main girder head, and also construct up to the upper main tower which will be the anchoring block on the main tower side,
Assembling the wagon on the main girder column head, constructing the fixing part that will be the first diagonal cable of the main girder, tensioning the first diagonal cable, and tensioning the diagonal cable while repeating the construction of the main tower and the main girder at the same time. Build a cable-stayed bridge.

[0011]

EXAMPLES Examples will be described below with reference to FIGS.

First, (1) in FIG. 1, the block C of the corbel portion
1 to C5 and blocks T1 and T2 of the main tower are constructed.

(2) Next, in FIG. 2, the frame scaffolding is refilled and blocks T3 to T6 of the main tower and the lower horizontal beams are constructed.
At the same time, the main girder stigmas H1 and H2 are constructed.

(3) Next, the main towers T7 to T9 are constructed in FIG. 3, and the block T9 in the main tower portion is used as the fixing portion on the main tower side. Further, the wagens W1 and W2 are assembled, the fixing portions K1 and K2 of the first diagonal cables B1 and B2 of the main girder are installed, and the diagonal cables are tensioned.

(4) A cable-stayed bridge is constructed by tensioning a diagonal cable while repeating construction of a main tower and a main girder at the same time.

[0016]

According to the present invention, since the main tower, which is the anchoring portion for the cable-stayed material, is constructed at the same time as the construction of the main girder column head, the construction period is shortened by the number of construction days of the main girder column head separately constructed as in the conventional case. To be done. Table 1 shows the average shortened days.
