Hereinafter, the construction error correction principle according to the shape of the coupling hole and the back hole will be described in detail with reference to FIGS. 7 to 10. FIG.

Fig. 7 is an exemplary view showing an example in which a girder bridge having a lateral support unit according to a specific embodiment of the present invention is installed. Fig. 8A and Fig. 8B are views showing a girder bridge having a lateral support unit according to a specific embodiment of the present invention. And FIGS. 9A and 9B illustrate an example of correcting a horizontal construction error of a girder bridge having a lateral support unit according to a specific embodiment of the present invention. FIGS. 10A and 10B are views illustrating an example of correcting a forward and backward construction error of a girder bridge having a lateral support unit according to a specific embodiment of the present invention. FIG.

First, considering the cause of occurrence of an installation position error of the lateral support unit 400 due to a construction error of the girder 200, when the girder 200 is pre-fabricated, the fixing means 210 This is because if the girder 200 is not accurately positioned at the designed position, a distance between the fixing means 210 is generated.

When the girder 200 is erroneously installed, the installation position of the transverse support unit 400 is changed.

At this time, an installation position error of the lateral support unit 400 generated is an error caused by a difference in mounting height of the girder 200, an error caused by a difference in the distance between the girders 200, and Can be distinguished by an error caused by a difference between a mounting point and an end point of the girder 200. [

That is, a coupling error of the transverse support unit 400 generated by the difference in embedding height between the girders 200 is referred to as a vertical error, and a vertical error is generated between the transverse support unit 400 generated by the difference in distance between the girders 200. [ The combined error of the transverse support unit 400 generated by the difference between the mount point and the end point of the girder 200 is referred to as an anteroposterior error.

At this time, in order to correct the vertical error, the back hole 423 of the first engaging member 420 and the back hole 433 of the second engaging member 430 or the coupling of the first engaging member 420 The hole 425 and the coupling hole 435 of the second coupling member 430 may be formed in the vertical direction.

8A and 8B, when a vertical error is generated due to a difference in embedment height between the girders 200, the vertical holes of the back hole and the coupling hole formed in the vertical length direction The installation position of the first engagement member 420 and the second engagement member 430 can be moved to correct the vertical error.

In order to correct the horizontal error, the coupling hole 425 of the first coupling member 420 and the coupling hole 435 of the second coupling member 430 may be formed in the horizontal direction.

9A and 9B, when a horizontal error is generated due to a difference in separation distance between the girders 200, The installation position of the member 410 can be moved to correct the horizontal error.

The back hole 423 of the first engaging member 420 and the back hole 433 of the second engaging member 430 may be formed in the horizontal length direction to correct the forward and backward errors.

10A and 10B, when a front-to-back error is generated due to a difference between a mount point and an end point of the girder 200, The installation position of the first coupling member 420 and the second coupling member 430 can be moved to correct the forward and backward errors.

When the back hole 423 of the first coupling member 420 and the back hole 433 of the second coupling member 430 are formed in the vertical length direction, When the second coupling member 430 and the girder 200 are coupled, the coupling position of the coupling surface can be moved by the vertical load. Therefore, in order to prevent the vertical coupling, It is preferable that the back hole 423 of the member 420 and the back hole 433 of the second coupling member 430 are formed in a horizontal lengthwise direction or a circular shape.

In the lateral support unit 400 having the rear hole and the coupling hole as described above, the rear hole 423 of the first coupling member 420 is formed in a horizontal lengthwise or circular shape, And the rear hole 433 of the second coupling member 430 is formed in the horizontal length direction and the coupling hole 425 of the second coupling member 430 is formed in the vertical direction. The coupling hole 435 may be formed in the horizontal length direction.

The first engaging member 420 and the second engaging member 430 may be coupled to the girder 200 such that the transverse supporting unit 400 is coupled to the girder 200. In the first engaging member 420, The second hole 423 is formed in the horizontal length direction, the coupling hole 425 is formed in the horizontal length direction, the back hole 433 is formed in the horizontal length direction or circular shape in the second coupling member 430, And the second electrode 435 may be formed in the vertical direction.

The first engaging member 420 and the second engaging member 430 are formed of the same material as the engaging hole 423 and the back hole 425 of the first engaging member 420, Various examples may be applied to allow correction of a vertical installation error, a horizontal installation error, and a backward installation error by organically combining the shapes of the coupling hole 433 and the back hole 435 of the coupling member 430 have.

In the meantime, when the coupling hole 423 and the back hole 425 are formed, the transverse support unit 400 can support the horizontal support unit 400 in the horizontal and vertical directions, The horizontal support unit 400 can be moved in the horizontal and vertical directions at the coupled position.

Hereinafter, with reference to FIGS. 4 and 6, a detailed description will be given of a structure for preventing the engagement position of the lateral support unit 400 from being shifted in a girder bridge having a lateral support unit according to a specific embodiment of the present invention I want to.
