Description

[0001] The present invention relates to a method of constructing a wind cable,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wind cable construction method, and more particularly, to a wind cable construction method in which a wind cable installed to prevent a left- The present invention relates to a method of constructing a wind cable.

A bridge is a structure that is installed to naturally induce a flow of a vehicle or a walk by crossing a natural valley or a river, or crossing a road or a railroad. Generally, long bridges are preferred where bridges are to be installed, possibly reducing the number of bridges, and this tendency is especially true when bridges are installed in an environment where natural degradation needs to be minimized.

On the other hand, as the quality of life of the people is increasingly emphasized, suspension bridges that have aesthetically superior functions are emphasized as the best if bridges between long bridges should be installed. Furthermore, since the suspension bridge is very friendly to the natural environment due to its structural characteristics, if the island is connected to an island or installed in a valley or a river, and it is necessary to develop it as a tourist product, the suspension bridge system is actively used.

As shown in FIG. 6, a typical suspension bridge includes a main tower 3 facing each other at regular intervals, an anchor block 6 spaced apart from the main tower 3 by a predetermined distance, A pair of left and right main cables 4 fixed to the upper end of the main tower 3 by being fixedly coupled to the upper plate 2 and fixed at one end to the main cable 4, (5).

In the case where the area where the suspension bridge is installed is adjacent to a sea with a strong sea breeze or in a mountainous region with strong winds, it is a means for preventing the top plate from rocking due to wind, A wind cable is additionally installed. The wind cable and the top plate are connected as a plurality of auxiliary cables similar to the hanger cable.

When installing a wind cable additionally, both ends of each wind cable are spaced apart from the anchor block by a certain distance and fixedly connected directly to the ground or rock, as shown in the figure, or separated by a considerable distance from the anchor block A fixed block is provided and fixedly coupled. This is because the conventional method of fixing the wind cable in this manner follows the curvature of the wind cable. However, such a fixing method of the wind cable has various problems.

One of them is the deterioration of the natural environment. In order to fix the wind cable, an anchor bolt or the like is used to fix the wind cable to the natural rock or a separate support block should be laid on the ground. Anchor bolts are installed on the natural rock, In the process of digging the ground to a certain depth, the natural environment is inevitably damaged.

The other is that it is difficult to guarantee the structural stability of the bridge itself by the existing wind cable fixing method. This is because the pair of left and right main cables are fixedly coupled to a single support member called an anchor block, while the pair of right and left wind cables connected to the upper plate are fixedly coupled to each other so that the tension of the wind cable is adjusted to a constant value This is because it is practically very difficult to fix it.

In addition, when the suspension bridge is constructed, the ground on which the both ends of the suspension bridge are installed is not completely the same, and rather than providing a symmetrical environment as the ideal condition for the installation, in most cases, Structure. It is very obvious that each wind cable can not properly cope with winds blowing more than a certain strength to the upper plate in a state where each wind cable is fixedly connected to the asymmetric structure ground. If such a phenomenon is repeated, There is seriousness.

This can be done by using bolts or bolts.

When the first and second mounting frames 32 and 36 are installed on the upper surfaces of the first and second main tower bases 12 and 16 and the first and second main tower bases 14 and 16, , 18) are installed. Thus, each of the first and second mounting frames 32 and 36 is integrated with each of the primary first and second pivot bases 12 and 16 by the secondary first and second pivot base 14 and 18 . When this step is completed, the base of the pylon is completed.

When the first and second stationary frames 32 and 36 are integrated with the base of the main tower, as shown in FIG. 1D, the first and second stationary frames 32 and 36 are disposed on the upper surfaces of the first and second main tower bases 14 and 18, Two main towers 42, 46 and third and fourth main towers 44, 48 are installed. Each pylon is made of steel, but may be made of reinforced concrete or concrete depending on the design. Reference numerals 1 and 3 denote connecting girder bridges for connection, and connect each tower block and each anchor block.

When the main tower is installed, the first and second main cables 52 and 56, which are a pair of left and right main cables 52 and 56, are spaced apart from each other by a predetermined distance. Each of the first and second main cables 52 and 56 supports the upper plate and each of the first and second main cables 52 and 56 is fixed to the upper surfaces of the first and second anchor blocks 22 and 26. The first and second main towers 42 and 46 And the third and fourth main towers 44 and 48, respectively. Both ends of each of the first and second main cables 52 and 56 can be fixed to each of the first and second anchor blocks 22 and 26 via tension adjusting means although not clearly shown in the drawing.

When the first and second main cables 52 and 56 are installed, the hanger cables 54 and 58 are laid as shown in FIG. 1F. The hanger cables 54 and 58 are directly connected to the upper plate to be described later, and are formed of a plurality of hanger cables 54 and 58 which are spaced apart from each other by a predetermined distance. Each of the hanger cables 54 and 58 is fixedly connected to the first and second main cables 52 and 56, do. Reference numeral 5 denotes a lower cable.

When the hanger cables 54 and 58 are installed, an upper plate composed of a plurality of treads 55 is installed as shown in FIG. In the case of installing the upper plate, a plurality of cross beams (not shown) are disposed at the lower portion of the lower cable, both ends of each of the cross beams are fixedly connected to the hanger cables 54 and 58, . ≪ / RTI > This is well known in the related art and will not be described in detail.

When the upper plate is installed, the first and second wind cables 62 and 66 are laid as shown in Fig. 1H. The first and second wind cables 62 and 66 serve as means for absorbing the left and right swings of the upper plate. The first and second wind cables 322 and 362 and the second and fourth cradles 326 and 326 366 and 366. Each end portion of each of the first and second loading platforms 322 and 362 and the second and fourth loading platforms 326 and 366 are connected to the first and second loading platforms 322 and 366, The auxiliary anchor blocks 222 and 226, and the third and fourth auxiliary anchor blocks 262 and 266, respectively.
